Automobile pickup bed roof

An automobile pickup bed roof (100) with an entrance passage as a door panel or window panel (118), having a hinge fixing unit (120) mounted on a window frame (119) of the automobile pickup bed roof (100) and fixing a hinge (121) attached to the window panel (118) enabling the window panel (118) to be opened and closed, wherein the hinge fixing unit (120) comprising an insertion rod (123), a body (124), a spring (125), and a latch (126), is characterized by:

• the insertion rod (123) is in the form of a pipe that can be slid over its length, wherein the insertion rod (123) has one end being inserted and attached thereto with the spring (125) and other part of the insertion rod (123) is inserted and attached to the hinge (121), the insertion rod (123), the body (124), the spring (125), and the latch (126) are assembled all together as a unit, whereby one part of the body (124) is attached to the window frame (119) of the automobile pickup bed roof (100), on a side of the body (124), there is a through hole extending from one end of the body to the other end, the insertion rod (123) is inserted into the inside of the body (124) from one end of the body, a first end rod fixing part (127) covers one end of the insertion rod (123), a spring fixing slot (128) is for inserting the spring (125) into the spring fixing slot (128), the insertion rod (123) is inserted into the spring fixing slot (128) and abut against the spring (125) so that it is in a fixed position, a latch sliding slot (129), which is parallel to the spring fixing slot (128) is for guiding the latch (126) to move within that slot securely, at the other end of the latch sliding slot (129), there is provided with a groove (130), in which the latch (126) can be locked and cannot be moved by a biasing force of the spring (125), a mid-rod fixing part (131) is a part that covers and holds part of the insertion rod (123), allowing the insertion rod (123) to slide within the mid-rod fixing part back and forth securely, a hinge fixing slot (132) is provided at one end of the hinge (121), which has a hole (122) being aligned such that the hinge can be fitted in the hinge fixing slot (132), allowing the insertion rod (123) to slide into and secure with the hinge (121), a second end-rod fixing part (133) is a part that covers the other end of the insertion rod (123);
• the spring (125) is inserted into the spring fixing slot (128), while having the insertion rod (123) abutted against the spring (125) resulting in the spring staying in a stationary position, whereby one end of the spring (125) abuts against a wall of the spring fixing slot (128) and the other end of the spring (125) attaches or abuts against the insertion rod (123);
• the latch (126) having one end connected with one part of the insertion rod (123), the latch (126) is capable of sliding inside the spring fixing slot (128), the other end of the latch (126) protrudes outward from the latch sliding slot (129), wherein the latch sliding slot (129) is parallel to the spring fixing slot (128), the end part of the latch that protrudes outside is for manipulation the latch by sliding back and forth.
