## Abstract

A drive module for a skateboard, the drive module comprising at least one axle with at least one wheel which is or can be driven by an electric motor, and a frame, which is connected to the axle and has a receiving space for an energy storage unit, in particular for a secondary battery, the drive module being replaceably connectible to the skateboard. Also, a set and a skateboard comprising the drive module.

## Claims

### Claim 1

A drive module for a skateboard, the drive module comprising:
an axle with at least one wheel, which is configured to be driven by an electric motor, and
a frame, which is connected with the axle, and has a receiving space for an energy storage unit,
wherein the drive module is configured to be replaceably connectible with the skateboard,
wherein the electric motor is connected with a controller, which is configured to be electrically connected with the energy storage unit,
wherein the frame forms at least one protective bracket,
wherein the frame, in particular the at least one protective bracket, at least partially envelops the controller housing, and
wherein the controller housing has a plug contact for electrically connecting the energy storage unit with the controller.

### Claim 2 (depends on 1)

The drive module according to claim 1, wherein the frame comprises a base plate for the axle, and is detachably connectible with a deck of the skateboard.

### Claim 3 (depends on 2)

The drive module according to claim 2, wherein the frame has a support plate, which is configured to be connected with the deck of the skateboard independently of and spaced apart from the base plate.

### Claim 4 (depends on 3)

The drive module according to claim 3, wherein the frame has a positive-locking element, in particular a keyhole opening, which is formed in the support plate.

### Claim 5 (depends on 3)

The drive module according to claim 3, wherein the at least one protective bracket connects the support plate with the base plate.

### Claim 6 (depends on 1)

The drive module according to claim 1, wherein the frame has a latching mechanism for fixing the replaceable energy storage unit in place.

### Claim 7 (depends on 2)

The drive module according to claim 2, wherein the axle has an axle carrier, which in particular is hinged with the base plate, wherein a cable duct is formed in the axle carrier.

### Claim 8 (depends on 1)

The drive module according to claim 1, wherein the electric motor comprises a wheel hub motor.

### Claim 9 (depends on 1)

A set comprising:
a drive module according to claim 1; and
a retaining bolt,
wherein the retaining bolt is fixedly connectible with a skateboard deck and is connectible with the frame of the drive module so that the drive module is configured to be unlatched from the skateboard deck.

### Claim 10 (depends on 9)

The set according to claim 9, wherein the retaining bolt is configured to be connected with the skateboard deck with screws or adhesive.

### Claim 11 (depends on 9)

The set according to claim 9, further comprising a replaceable energy storage unit, which is configured to be arranged in the receiving space of the frame of the drive module.

### Claim 12 (depends on 1)

A skateboard comprising:
a deck; and
a drive module according to claim 1, which is connected with the deck.

### Claim 13 (depends on 1)

The drive module according to claim 1, wherein the controller housing has a latching mechanism for fixing the replaceable energy storage unit in place.

### Claim 14 (depends on 1)

The drive module according to claim 1, wherein the energy storage unit comprises an accumulator.
