Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, specifically to an electric lifting structure and an electric two-wheeled vehicle lifting rack. Background Technology

[0002] Some electric two-wheelers are equipped with electric landing gear to assist with balance while riding. The electric landing gear has auxiliary wheels on both sides that contact the ground. Riders can control the raising or lowering of the landing gear via buttons, adjusting it according to their riding needs. Chinese invention patent CN116118908A discloses an automatic landing gear for a two-wheeled electric vehicle, which mainly uses an electric push rod to drive the landing gear to raise or lower. Specifically, when the landing gear needs to be lowered, the output shaft of the electric push rod extends; when the landing gear needs to be retracted, the output shaft retracts. However, because the electric push rod needs to travel a certain distance during operation, sufficient installation space is required on the landing gear, resulting in a relatively large overall size of the landing gear and a significant space occupation for the electric two-wheeler. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides an electrically operated lifting structure, including a base plate and a lifting mechanism. The lifting mechanism includes a drive motor and a hinge assembly. The drive motor is connected to the base plate, and a cantilever assembly is provided on the motor shaft of the drive motor. The hinge assembly is provided with an auxiliary wheel adapted to contact the ground. One side of the hinge assembly is hinged to the base plate, and the cantilever assembly is connected to the hinge assembly. When the drive motor drives the cantilever assembly to swing, the cantilever assembly is adapted to drive the side of the hinge assembly away from the base plate to rotate, unfold, or fold to drive the auxiliary wheel to rise or fall.

[0004] Optionally, the electric lifting structure also includes a crossbeam frame, with two sets of the base plate and the lifting mechanism symmetrically arranged at both ends of the crossbeam frame, and the base plate being fixedly connected to the crossbeam frame.

[0005] Optionally, the auxiliary wheel is rotatably connected to the hinge assembly.

[0006] Optionally, the cantilever assembly includes a cantilever plate and a shock absorber. One side of the cantilever plate is connected to the motor shaft of the drive motor and rotates synchronously, while the other side is hinged to the shock absorber.

[0007] Optionally, the hinge assembly includes a first hinge rod and a lifting link, with the two sides of the first hinge rod respectively hinged to the base plate and the lifting link, and the side of the shock absorber away from the cantilever plate hinged to the first hinge rod.

[0008] Optionally, the hinge assembly further includes a second hinge rod located below the first hinge rod, with one side of the second hinge rod hinged to the base plate and the other side hinged to the middle of the lifting link.

[0009] Optionally, the lifting link has multiple adjusting threaded holes on the side away from the base plate, and the multiple adjusting threaded holes are arranged at intervals in the vertical direction. The auxiliary wheel is adapted to be connected to any one of the adjusting threaded holes by bolts.

[0010] Optionally, a mounting plate is fixed on the substrate, and the drive motor is mounted on the mounting plate.

[0011] Optionally, a rotation limiting plate is installed on the mounting plate, which is adapted to limit the rotation range of the cantilever plate.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. Compared to electric push rods, drive motors have no travel limitations and occupy less space. After the drive motor drives the cantilever assembly to swing and raise the auxiliary wheel, the hinge assembly can drive the auxiliary wheel to a folded state, further reducing the volume of the entire electric lifting structure. This makes the entire electric lifting structure smaller and occupies less space on the electric two-wheeler when folded up.

[0014] 2. The two lifting mechanisms are directly and independently controlled by two drive motors, so that the auxiliary wheels can respond in a timely manner when they rise or fall;

[0015] 3. The auxiliary wheel is rotatably connected to the articulated assembly. If the landing gear is in the lowered state during the riding of the electric two-wheeler, the auxiliary wheel will also rotate relative to the wheel when turning, making the turning smoother.

[0016] 4. The first hinge rod and the second hinge rod form a double hinge connection structure, which makes the shock absorber drive the lifting link to rise and fall more stably;

[0017] 5. The shock absorber allows the auxiliary wheel to adaptively raise and absorb shocks as it rolls on uneven ground, improving driver comfort.

[0018] In addition, this utility model provides an electric two-wheeled vehicle landing gear, including the electric landing structure as described above.

[0019] Compared with the prior art, the electric two-wheeled vehicle landing gear described in this utility model has the same advantages as the electric landing structure described above, which will not be repeated here. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-3 This application will be described in further detail.

[0025] In a first aspect, this utility model embodiment provides an electrically operated lifting structure, referring to... Figure 1 and Figure 2 The electric lifting structure includes a base plate 1, a lifting mechanism 2, and a crossbeam 3. Two sets of base plates 1 and lifting mechanisms 2 are provided, with each set of lifting mechanisms 2 connected to a corresponding base plate 1. The two base plates 1 are fixedly connected to both ends of the crossbeam 3, which is adapted to be fixedly connected to the frame of the electric vehicle. The lifting mechanism 2 includes a drive motor 21 and a hinge assembly 22. The drive motor 21 is connected to the base plate 1, and a cantilever assembly 23 is provided on the motor shaft of the drive motor 21. The hinge assembly 22 is provided with an auxiliary wheel 24 adapted to contact the ground. One side of the hinge assembly 22 is hinged to the base plate 1, and the cantilever assembly 23 is connected to the hinge assembly 22. When the drive motor 21 drives the cantilever assembly 23 to swing, the cantilever assembly 23 is adapted to drive the side of the hinge assembly 22 away from the base plate 1 to rotate, unfold, or fold, thereby driving the auxiliary wheel 24 to rise or fall.

[0026] In this embodiment, the base plate 1 is preferably fixedly connected to the crossbeam frame 3 with bolts, making disassembly convenient during maintenance of the electric lifting structure. In another embodiment, the base plate 1 is welded to the crossbeam frame 3. A mounting plate 11 is welded to the side of the base plate 1 facing away from the crossbeam frame 3, and the drive motor 21 is mounted on the mounting plate 11 with bolts. When maintenance of the drive motor 21 is required, it is not necessary to disassemble the base plate 1; instead, the drive motor 21 can be directly removed from the mounting plate 11, further improving the convenience of maintenance and disassembly.

[0027] Reference Figure 1 and Figure 2 The cantilever assembly 23 includes a cantilever plate 231 and a shock absorber 232. Preferably, in this embodiment, the shock absorber 232 is a conventional spring shock absorber 232. One side of the cantilever plate 231 is connected to the motor shaft of the drive motor 21, and the drive motor 21 can drive the cantilever plate 231 to swing. The side of the cantilever plate 231 away from the motor shaft of the drive motor 21 is hinged to the shock absorber 232, while the side of the shock absorber 232 away from the cantilever plate 231 is hinged to the hinge assembly 22. Therefore, after the cantilever plate 231 swings, it can drive the shock absorber 232 to move, and after the shock absorber 232 moves, it can drive the hinge assembly 22 to either an unfolded or folded state.

[0028] When the cantilever plate 231 moves the shock absorber 232 to drive the articulation assembly 22 into the unfolded state, the auxiliary wheel 24 descends and contacts the ground. The vibration experienced by the auxiliary wheel 24 during its rolling on the uneven ground is transmitted to the shock absorber 232 through the articulation assembly 22. As a result, the auxiliary wheel 24 can adaptively lift and absorb shocks under the action of the shock absorber 232, thereby improving the driver's comfort.

[0029] When the cantilever plate 231 moves the shock absorber 232 to drive the hinge assembly 22 into a folded state, the auxiliary wheel 24 rises and does not contact the ground.

[0030] Reference Figure 1 and Figure 2 A rotation limit plate 12 is bolted onto the mounting plate 11. When the auxiliary wheel 24 is in the lowered state and in contact with the ground, the cantilever plate 231 and the shock absorber 232 are on the same straight line. The cantilever plate 231 will abut against the rotation limit plate 12 and will not be able to continue to rotate, thus limiting the rotation range of the cantilever plate 231 and ensuring the accuracy of the cooperation between the cantilever plate 231 and the shock absorber 232.

[0031] The hinge assembly 22 is located on the side of the base plate 1 away from the crossbeam 3. The hinge assembly 22 includes a first hinge rod 221, a lifting link 222, and a second hinge rod 223. One side of the first hinge rod 221 is hinged to the base plate 1, and the other side is hinged to the top of the lifting link 222. The shock absorber 232 is hinged to the first hinge rod 221 on the side near the lifting link 222. In another embodiment, the shock absorber 232 can also be directly hinged to the lifting link 222. The second hinge rod 223 is located below the first hinge rod 221. One side of the second hinge rod 223 is hinged to the base plate 1, and the other side is hinged to the middle of the lifting link 222, thus forming a double hinge connection structure, which makes the lifting link 222 more stable when the shock absorber 232 drives it to rise and fall.

[0032] Reference Figure 2 and Figure 3The auxiliary wheel 24 is located on the side of the bottom of the lifting link 222 facing away from the base plate 1, and moves synchronously with the lifting link 222. A first hinge is provided on the side of the auxiliary wheel 24 near the lifting link 222, and a second hinge is provided on the side of the lifting link 222 near the auxiliary wheel 24. The second hinge is connected to the lifting link 222 by bolts. The hinged connection between the first and second hinges allows the auxiliary wheel 24 to rotate to a certain extent in the horizontal direction relative to the lifting link 222. When the auxiliary wheel 24 is in contact with the ground, it also rotates relative to the ground when the electric two-wheeled vehicle turns, making the turning smoother.

[0033] Reference Figure 2 and Figure 3 The lifting link 222 has multiple threaded holes spaced vertically on the side near the auxiliary wheel 24. The bolt for mounting the second hinge member on the lifting link 222 is threaded into any one of the threaded holes, and the bottom of the lifting link 222 does not contact the ground regardless of which threaded hole the second hinge member is located in through the bolt. In this embodiment, two threaded holes are preferably provided.

[0034] The implementation principle of the electrically operated lifting structure in this application embodiment is as follows: Compared with an electric push rod, the drive motor 21 has no stroke limitation and occupies less space. When the cantilever plate 231 moves the shock absorber 232 to drive the hinge assembly 22 into the unfolded state, the auxiliary wheel 24 descends and contacts the ground. The vibration experienced by the auxiliary wheel 24 during rolling on uneven ground is transmitted to the shock absorber 232 through the hinge assembly 22, thereby enabling the auxiliary wheel 24 to adaptively lift and absorb shock under the action of the shock absorber 232, improving the driver's comfort. When the cantilever plate 231 moves the shock absorber 232 to drive the hinge assembly 22 into the folded state, the auxiliary wheel 24 rises and does not contact the ground.

[0035] Secondly, another embodiment of this utility model provides an electric two-wheeler landing gear, which is equipped with the electric landing structure described in the first aspect. The crossbeam 3 is adapted to be fixedly connected to the electric vehicle's fork. The hinge assembly 22 can drive the auxiliary wheel 24 into a folded state, further reducing the volume of the entire electric landing structure, making the overall electric landing structure smaller and occupying less space on the electric two-wheeler when folded.
