[0024] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:

[0025] See Figures 1-6, A vehicle drive structure includes a motor and a reducer. In this embodiment, the motor and the reducer are installed on the vehicle frame 3. The motor includes a motor housing 1, and the reducer includes a reducer housing 4, both of which are fixedly connected to the vehicle frame 3.

[0026] Specifically, the reducer housing 4 includes a first housing 10 and a second housing 11, and the motor housing 1 includes a third housing 12 and a fourth housing 13. The first housing 10 and the second housing 11 are detachably connected, and they can be connected or disassembled by means of bolts and nuts. Similarly, the third housing 12 and the fourth housing 13 are also detachably connected, that is, the third housing 12 and the fourth housing 13 are also connected or disassembled by means of bolts and nuts.

[0027] Furthermore, in order to connect the reducer housing 4 and the motor housing 1 to the vehicle frame 3, a first extension arm 2 is extended on the motor housing 1, and a second extension arm 6 is provided on the reducer housing 4. Further, the first extension arm 2 and the second extension arm 6 are both fixedly arranged on the vehicle frame 3.

[0028] The vehicle frame 3 is provided with a first mounting hole 7 and a second mounting hole 8, which are concentrically arranged. At the same time, by placing the first extension arm 2 and the second extension arm 6 between the first mounting hole 7 and the second mounting hole 8, a fastener can be used to fixedly arrange them.

[0029] Specifically, the vehicle frame 3 is provided with a number of connecting plates 9, and the corresponding connecting plates 9 are provided with the first mounting hole 7 or the second mounting hole 8, so that they are evenly distributed on both sides of the vehicle frame 3, so that the space between the connecting plates 9 can allow the first extension arm 2 and the second extension arm 6 to enter synchronously.

[0030] The first housing 10 and the second extension arm 6 are integrally formed, and the fourth housing 13 and the first extension arm 2 are integrally formed. At the same time, after the second housing 11 and the third housing 12 are connected into one body, the reducer and the motor are integrated into a whole.

[0031] At the same time, the second extension arm 6 on the first housing 10 and the first mounting hole 7 can be locked by a shorter fastener. Similarly, the first extension arm 2 on the fourth housing 13 and the second mounting hole 8 are also the same. In this way, the reducer and the motor can be fixed on the vehicle frame 3.

[0032] Another way is to pass a longer fastener through the first mounting hole 7, the first extension arm 2, the second mounting hole 8, and the second extension arm 6 to achieve the connection.

[0033] At the same time, the vehicle frame 3 also includes a drive shaft 5 for assembling a drive wheel, wherein the drive shaft 5 is transmission-connected to the reducer, and the drive shaft 5 passes through the reducer housing 4 and is connected to the reducer body 14, so that the reducer can drive the drive shaft 5 to move, and the drive shaft 5 drives the drive wheel to move.

[0034] At the same time, the reducer and the motor are transmission connected. Specifically, an output shaft 15 is provided through the motor housing 1. The output shaft 15 is inserted into the reducer housing 4 and connected to the reducer body 14. When the motor is running, the output shaft 15 drives the reducer and the drive shaft 5 to run.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
