Description

Technical Field

[0001] This application relates to the field of two-wheeled electric vehicle technology, and in particular to a mid-mounted motor rear horizontal fork structure and a two-wheeled electric vehicle. Background Technology

[0002] The rear swingarm, a key component of two-wheeled electric vehicles, is located at the bottom and serves to secure the motor to the rear wheel. Two-wheeled electric vehicles typically use hub motors, integrated within the drive wheel. This design minimizes space requirements, facilitates installation, and offers low cost and direct transmission. However, the weight of the hub motor results in an excessively heavy drive wheel, impacting shock absorption and riding comfort. Furthermore, the hub's direct contact with the ground creates a harsh working environment, affecting the motor's lifespan. Additionally, the lack of a reduction gear mechanism in hub motor-driven systems hinders the achievement of high torque. Therefore, mounting the motor securely to the rear swingarm avoids these drawbacks.

[0003] For example, Chinese utility model patent CN214296318U discloses a motor fixing device for a two-wheeled electric vehicle. By fixing the motor, rear horizontal fork, and rear wheel axle into one unit with a bracket, the distance between the motor and the rear wheel axle can be kept constant. The transmission distance between the motor and the rear wheel axle will not change when the two-wheeled electric vehicle is bumpy, thus overcoming the instability of motor transmission and improving the user experience and service life of the two-wheeled electric vehicle. In addition, the motor is located on both sides of the symmetrical rear horizontal fork, so that the motor is in the middle position of the two-wheeled electric vehicle, which also solves the problem of the center of gravity being off-center in electric motorcycles.

[0004] However, the aforementioned patent requires the disassembly of all components of the rear swingarm during motor disassembly, which is cumbersome, labor-intensive, and affects work efficiency. Utility Model Content

[0026] Reference Figures 1 to 3 The first aspect of this application provides a mid-mounted motor rear swingarm structure, including: a rear swingarm body; a first bracket 200, detachably disposed on one side of the rear swingarm body; a second bracket 300, integrally disposed on the other side of the rear swingarm body, the second bracket 300 and the first bracket 200 cooperating to form a mounting position; a motor 400 disposed at the mounting position, the two ends of the motor 400 being connected to the first bracket 200 and the second bracket 300 respectively; wherein, when the first bracket 200 is separated from the rear swingarm body, one side of the mounting position is open to allow the motor 400 to be inserted or removed.

[0027] By placing the motor 400 between the first bracket 200 and the second bracket 300, the overall structural layout can be simplified and space can be saved. The structure is also highly stable and can better withstand the weight of the motor 400 and vibrations and impacts during operation. By detachably mounting the first bracket 200 to the rear swingarm body, when disassembling the motor 400, it is only necessary to separate the first bracket 200 from the rear swingarm body, opening one side of the mounting position, and the motor 400 can be removed from the mounting position. At this time, it is not necessary to disassemble the rear swingarm body, which makes the disassembly and assembly operation simple, facilitates the later maintenance or replacement of the motor 400, reduces labor intensity, and improves work efficiency.

[0028] The rear swingarm body includes a first support arm 110 and a second support arm 120. The front ends of the first support arm 110 and the second support arm 120 are connected by a connecting arm 130. A first bracket 200 is detachably mounted on either the first support arm 110 or the connecting arm 130, and a second bracket 300 is integrally mounted on the second support arm 120. The first support arm 110 and the second support arm 120 are configured as square tubular structures, while the first bracket 200 and the second bracket 300 are configured as plate-like structures. This simplifies the manufacturing process, improves production efficiency, and reduces production costs.

[0029] Reference Figures 1 to 3 Furthermore, the first bracket 200 is provided with a first extension 210, and the first extension 210 is provided with a first clearance position 220. The first support arm 110 or the connecting arm 130 is embedded in the first clearance position 220, and the first support arm 110 or the connecting arm 130 is detachably connected to the first extension 210. By embedding the first support arm 110 and / or the connecting arm 130 into the first clearance position 220, the contact area between the first bracket 200 and the first support arm 110 and / or the connecting arm 130 can be increased, thereby improving the stability of the connection and also making the structure reasonable and compact. Specifically, the first support arm 110 or the connecting arm 130 is provided with a first connecting part 140, and the first extension 210 and the first connecting part 140 are connected by a first fastener 160. The first fastener 160 is set as a first bolt, which makes the connection more secure and facilitates disassembly and assembly. In this embodiment, an angle iron 150 is provided between the first support arm 110 and the connecting arm 130, and the first connecting part 140 is provided on the angle iron 150. This can improve the strength between the first support arm 110 and the connecting arm 130, making the connection between the two more stable and reliable.

[0030] In some other embodiments of this application, the first connecting part 140 may also be directly disposed on the first support arm 110 or the connecting arm 130, and this application does not limit this.

[0031] Reference Figures 1 to 3 It is conceivable that the second bracket 300 is provided with a second extension 310, the second extension 310 is provided with a second clearance position 320, the second support arm 120 and / or connecting arm 130 are embedded in the second clearance position 320, and the second support arm 120 and / or connecting arm 130 are welded and fixed to the second extension 310. By embedding the second support arm 120 and / or connecting arm 130 into the second clearance position 320, the contact area between the second bracket 300 and the second support arm 120 and / or connecting arm 130 can be increased, making the weld between the second bracket 300 and the second support arm 120 and / or connecting arm 130 more stable.

[0032] In this embodiment, the first bracket 200 has a first hollow portion 230, the second bracket 300 has a second hollow portion 330, the tail end of the motor 400 is located in the first hollow portion 230, and the output end of the motor 400 passes through the second hollow portion 330. This not only makes the overall structure reasonable and compact, but also reduces the weight of the overall structure. The first bracket 200 has a recess 240 on the side of the first hollow portion 230, and the junction box at the end of the motor 400 is located within the recess 240, further improving the rationality and compactness of the structure, reducing the overall space occupied, and providing more installation space for other components.

[0033] Reference Figures 1 to 3 In some embodiments of this application, a connecting pipe 340 is integrally provided on the side of the second bracket 300 away from the rear swingarm body, and the first bracket 200 is detachably connected to the connecting pipe 340. The connecting pipe 340 facilitates the connection between the rear swingarm body and the front of the vehicle, resulting in a simple structure and easy operation. Specifically, the first bracket 200 has a third extension 250, and the connecting pipe 340 has a second connecting portion 350. The third extension 250 and the second connecting portion 350 are connected by a second fastener 360, which is a second bolt. More specifically, the first bracket 200 has a third clearance position 260, and the connecting pipe 340 is embedded within the third clearance position 260. The third extension 250 and the second connecting portion 350 are then connected by the second fastener 360, thereby improving the stability of the connection and reducing the space occupied, resulting in a more rational and compact structure.

[0034] A second aspect of this application provides a two-wheeled electric vehicle, including the mid-mounted motor and rear horizontal fork structure described in the first aspect of this application.

[0035] By applying the mid-mounted motor rear swingarm structure described in the first aspect of this application, the motor 400 is positioned between the first bracket 200 and the second bracket 300, which simplifies the overall structural layout and saves space. Furthermore, the structure boasts high stability and can better withstand the weight of the motor 400 and vibrations and impacts during operation. By detachably mounting the first bracket 200 to the rear swingarm body, disassembling the motor 400 only requires separating the first bracket 200 from the rear swingarm body, opening one side of the mounting position, and then removing the motor 400 from the mounting position. This eliminates the need to disassemble the rear swingarm body, simplifying the disassembly and assembly process, facilitating future maintenance or replacement of the motor 400, reducing labor intensity, and improving work efficiency.

[0036] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments.
