Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model provides a steering rod and its vehicle, which aims to improve the bending and torsional strength of the steering rod.

[0031] refer to Figure 1 and Figure 3 This embodiment relates to a steering rod 1, which includes a first rod 11 and a second rod 12 connected to each other. The second rod 12 has a hollow cavity 121 for setting a reinforcing plate 122 inside. The reinforcing plate 122 is arranged in the hollow cavity 121 along the axial direction of the second rod 12. The end of the first rod 11 away from the second rod 12 is used to connect with the vehicle steering wheel 7, and the end of the second rod 12 away from the first rod 11 is used to connect with the locking block that transmits steering torque to the vehicle.

[0032] Among them, the steering rod 1 is an integrally formed structural component. Therefore, when passing through complex road conditions or driving at high speed, the second rod 12 is closer to the front fork of the vehicle than the first rod 11, and will be subjected to stronger impact forces. By opening a hollow cavity 121 inside the second rod 12, the overall weight is reduced, and a reinforcing plate 122 along the axial direction of the second rod 12 is set inside, thereby improving the bending and torsional strength of the second rod 12.

[0033] refer to Figure 2 and Figure 4 In this embodiment, the second rod 12 is provided with a bent section 123, with a bending angle greater than 90 degrees and less than 180 degrees, so that the steering wheel 7 installed on the steering rod conforms to the rider's grip distance, improving maneuverability. The first rod 11 includes an inner tube 111 and an outer tube 112 sleeved on the outer wall of the inner tube, with the outer wall of the inner tube 111 and the inner wall of the outer tube 112 fixedly connected. Based on the above overall design, unlike the prior art which adds welding or thickening treatment to key stress parts, this embodiment adopts different reinforcement methods for the high-force impact section and the low-force impact section of the steering rod 1, thereby achieving the effect of improving the overall structural strength of the steering rod 1.

[0034] refer to Figure 5This embodiment also relates to a vehicle, which includes a vehicle body equipped with the aforementioned steering lever 1. The vehicle body includes a chassis 2, a drive wheel assembly 3, a steering wheel 4, an electronic control unit 5, a battery unit 6, and a steering wheel 7. The drive wheel assembly 3, steering wheel 4, electronic control unit 5, battery unit 6, and steering wheel 7 are all mounted on the chassis 2. The end of the first lever 11 away from the second lever 12 is connected to the steering wheel 7, and the end of the second lever 12 away from the first lever 11 is connected to a locking block, which is connected to the steering wheel 4. The electronic control unit 5 and the drive wheel assembly 3 are both electrically connected to the battery unit 6. The electronic control unit 5 controls the start, stop, acceleration, and deceleration of the drive wheel assembly 3. The battery unit 6 can be selected from lithium-ion batteries, lithium polymer batteries, nickel-metal hydride batteries, solid-state batteries, lead-acid batteries, and hydrogen fuel cells, depending on the power supply method of the drive wheel assembly 3. Since the battery unit 6 and the electronic control unit 5 are set separately, the heat generated by the battery unit 6 is effectively prevented from affecting the electronic control unit 5.

[0035] refer to Figure 6 Further explanation of the chassis 2 structure: Chassis 2 includes a front carrier 21 and a rear carrier 22 detachably connected to the front carrier 21. The front carrier 21 is used to mount the battery unit 6, steering wheel 7, and steering wheel 4. The rear carrier 22 is used to mount the electronic control unit 5 and drive wheel assembly 3. The front carrier 21 includes a horizontal standing platform 211, a lower base 212, and a front mounting bracket 213. The battery unit 6 is mounted between the horizontal standing platform 211 and the lower base 212 and is sealed. The steering wheel 7 and steering wheel 4 are hinged to the front mounting bracket 213. The horizontal standing platform 211 supports the rider's feet and... Furthermore, a sealing structure is arranged between the lower base 212 and the battery unit 6 to enclose and seal the battery unit 6, thereby improving safety and waterproof performance. At the same time, the lower base 212 has a certain shock absorption function to protect the battery unit 6 from mechanical stress during operation. The front carrier 21 also includes a rear mounting bracket 214, and the rear carrier 22 is elastically connected to the rear mounting bracket 214. The rear carrier 22 includes a mounting cavity 221 for mounting the electronic control unit 5 and a shock absorption device 222 for mounting the drive wheel assembly 3. The mounting cavity 221 is equipped with a shock-absorbing pad and a sealing plate to achieve waterproof, sealing and dustproof functions.

[0036] In addition, a suspension system is arranged between the front carrier 21 and the steering wheel 4 to absorb the impacts and vibrations transmitted from the steering wheel 4 during vehicle operation.

[0037] refer to Figure 7Further explanation of the drive wheel assembly 3: The drive wheel assembly 3 includes a drive motor 31, a wheel rim 32, a wheel cover 33, and fixing bolts 34. The drive motor 21 is disposed inside the wheel cover 33, and the wheel rim 32 is detachably connected to the wheel cover 33 by the fixing bolts 34. The geometric center line of the wheel rim 32 coincides with the mass center line of the drive wheel assembly 3, thus forming a symmetrical structure. This effectively reduces the polarization or vibration problems caused by mass imbalance during the operation of the drive wheel assembly 3. At the same time, the width of the drive motor 31 is less than three-quarters of the width of the wheel rim 32, thus ensuring that the drive motor 31 can be compactly integrated within the width range of the wheel rim 32 without protruding outwards, maintaining the structural integrity of the wheel rim 32, thereby achieving a balanced mass distribution around the vertical center line of the drive wheel assembly 3.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
