In the first position, the door body closes an opening in a body of the motor vehicle and blocks access to the charging socket or to the tank inlet. In a second position, the door body releases the opening of the body of the motor vehicle and the access to the charging socket or to the tank inlet. Relative to the first position, the push-push mechanism is arranged on a different side of the axis of rotation than the first portion, supporting the panel body, of the door body. ## Claims ### Claim 1 A charging or tank door assembly of a motor vehicle, the charging or tank door assembly comprising: a base body configured to receive a charging socket or a tank inlet; a door body which is coupled to the base body at a pivot point such that it is pivotable about an axis of rotation defined by the pivot point and supports a panel body on a first portion, wherein, in a first position of the door body, the door body is configured to close an opening in a body of the motor vehicle and to block access to the charging socket or to the tank inlet, and wherein, in a second position of the door body, the door body is configured to release the opening of the body of the motor vehicle and the access to the charging socket or to the tank inlet; and a push-push mechanism configured to lock the door body and to release the door body in the first position thereof, wherein, relative to the first position of the door body, the push-push mechanism is arranged on a different side of the axis of rotation of the door body than the first portion, supporting the panel body, of the door body. ### Claim 2 (depends on 1) The charging or tank door assembly according to claim 1, wherein, relative to the second position of the door body, the push-push mechanism is arranged on a same side of the axis of rotation of the door body as the first portion, supporting the panel body, of the door body. ### Claim 3 (depends on 1) The charging or tank door assembly according to claim 1, wherein in the first position of the door body, a second portion of the door body cooperates with the push-push mechanism such that the second portion of the door body supports or forms a counter-lock cooperating with a lock of the push-push mechanism. ### Claim 4 (depends on 1) The charging or tank door assembly according to claim 1, wherein the first portion, supporting the panel body, of the door body is connected to the pivot point via a third portion of the door body, wherein a first leg of the third portion engages with the pivot point, wherein a second leg of the third portion engages in the first portion, and wherein the first leg and the second leg are connected via a connecting leg. ### Claim 5 (depends on 4) The charging or tank door assembly according to claim 4, wherein the second portion of the door body is formed as an extension of the connecting leg of the third portion of the door body. ### Claim 6 (depends on 4) The charging or tank door assembly according to claim 4, wherein the second portion of the door body extends the connecting leg of the third portion beyond the first leg thereof. ### Claim 7 (depends on 1) The charging or tank door assembly according to claim 1, wherein the push-push mechanism is arranged behind the body of the motor vehicle in a depression limited at least in sections by the base body. ### Claim 8 (depends on 1) The charging or tank door assembly according to claim 1, wherein a spring cooperates with the pivot point, a spring force of the spring displacing the door body to the second position. ### Claim 9 (depends on 1) A motor vehicle having the charging or tank door assembly according to claim 1. ### Claim 10 (depends on 4) The charging or tank door assembly according to claim 4, wherein the third portion is U-shaped. ### Claim 11 (depends on 1) The charging or tank door assembly according to claim 1, wherein the push-push mechanism comprises a push-push device or locking element. ### Claim 12 (depends on 1) The charging or tank door assembly according to claim 1, wherein in the first position of the door body, a second portion of the door body is configured to cooperate with the push-push mechanism such that the second portion of the door body supports or forms a counter-lock cooperating with a lock of the push-push mechanism, wherein the first portion, supporting the panel body, of the door body is connected to pivot point via a third portion of the door body, wherein a first leg of the third portion directly couples to the pivot point, wherein a second leg of the third portion is coupled to the first portion, and wherein the first leg and the second leg are ridgidly connected via a connecting leg, and wherein the second portion of the door body is an extension of the connecting leg of the third portion, the second portion extending beyond the first leg in a direction away from the first portion. ### Claim 13 A charging or tank door assembly of a motor vehicle, the charging or tank door assembly comprising: a base body forming a partial enclosure configured to receive a charging socket or a tank inlet; a door body, which is coupled to the base body at a pivot point such that it is pivotable about an axis of rotation, the door body further comprising a mating extent configured to mate with a panel body along a mating length, the mating length defined by all points of contact between the door body and the panel body, wherein, in a first position of the door body, the door body is configured to close an opening in a body of the motor vehicle and to block access to the charging socket or to the tank inlet by the panel body being positioned to mate with a portion of the body of the motor vehicle to block an opening of the partial enclosure of the base body, and wherein, in a second position of the door body, the door body is configured to release the opening of the body of the motor vehicle and the access to the charging socket or to the tank inlet by positioning the panel body away from the body of the motor vehicle; and a push-push mechanism configured to lock the door body and to release the door body in the first position thereof, wherein, relative to the first position of the door body, the push-push mechanism is arranged on a different side of the axis of rotation than all or most points of contact between the door body and the panel body.
