Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shock absorption, particularly to a shock absorption platform for a single-person mobility scooter. BACKGROUND

[0002] In the fields of military, fire fighting, search and rescue, and transportation, single-person mobility scooters provide significant support for soldiers, rescue personnel, and law enforcement personnel in high-intensity operating environments due to their electrical assistance systems and lightweight design. It not only improves the marching speed and reduces the load, but also shows irreplaceable advantages in long-distance marching or complex terrain. By reducing the physical exertion of the user, the scooter helps them complete their tasks more efficiently while ensuring that their physical and mental state remains at an optimal level.

[0003] The single-person mobility scooter needs to solve multiple problems such as protecting the load equipment, external impact, and adapting to complex environments and terrain while ensuring that the amount of carried supplies remains unchanged. Therefore, using a high-performance shock absorption device in the design of the single-person mobility scooter is a key link and an important part of the development.

[0004] Currently, the shock absorption devices available for selection mainly include spring shock absorbers, air bag shock absorbers, and shock absorption pads. These devices can handle the transportation of equipment and supplies with a certain load, but they cannot simultaneously meet the conditions of not losing power, not being harsh in use, having excellent buffering effect, and being highly adaptable to terrain environments. For example, in extremely rugged or irregular terrain, especially when quickly passing through large stones or deep holes, the shock absorption effect of the spring shock absorber may not be sufficient, causing vibrations to still be transmitted to the vehicle body, which can easily cause the shock absorber to be excessively compressed or fail, affecting the user experience. In extremely low or high temperature environments, the air bag material of the air bag shock absorber may harden or age, causing the air bag to leak, wear, and other changes, affecting the shock absorption effect. For complex terrain or high-speed driving, the shock absorption effect of the shock absorption pad is relatively poor, and it may not be able to effectively suppress large impacts, and vibrations may still be transmitted to the user. Moreover, the design of the shock absorption pad is usually fixed and cannot be automatically adjusted according to different use environments or loads, and its adaptability in dynamic or complex environments is poor.

[0031] Embodiment 1

[0032] The utility model discloses a damping platform for a follow-up power-assisted vehicle, including bearing platform 100 and symmetry installation in the bearing platform 100 both sides oil pressure spring damper 200, support frame 300 and hub motor 400.

[0033] Specifically, the four corners of the bearing platform 100 are provided with connecting seats 110 respectively.The connecting seat 110 includes a bottom plate 111 and ear seats 112 fixed vertically on both sides of the bottom plate 111.The bottom plate 111 is fixed on the bearing platform 100 by screws.

[0034] The oil pressure spring damper 200 is provided with ring holes 210 at both ends respectively.

[0035] The support frame 300 comprises a support plate 310, a connecting groove 320 and a connecting block 330. One end of the support plate 310 is provided with a through hole 311, and the connecting groove 320 and the connecting block 330 are respectively installed on both sides of the other end of the support plate 310 through screws or rivets, wherein the connecting block 330 is provided with a fixed clamping groove 331 on one side of the support plate 310.

[0036] The support frame 300 is arranged with the side with the connecting block 330 upward, and the end with the through hole 311 is rotationally connected with the lug seat 112 of the corresponding connecting seat 110 on the bearing platform 100 through a pin shaft.

[0037] The ring hole 210 at one end of the oil pressure spring shock absorber 200 is rotationally connected with the lug seat 112 of the corresponding connecting seat 110 on the bearing platform 100 through a pin shaft.

[0038] The ring hole 210 at the other end of the oil pressure spring shock absorber 200 is connected with the connecting groove 320 through a pin shaft, achieving connection with the top end of the support frame 300.

[0039] The hub motor 400 is located on both sides of the bearing platform 100, and the output shaft 410 at the center of the side surface is clamped in the fixed clamping groove 331 of the connecting block 330, achieving connection with the top end of the support frame 300. Specifically, the output shaft 410 is a D-shaped output shaft, and the shape of the fixed clamping groove 331 matches the shape of the output shaft 410.

[0040] The hub of the hub motor 400 is a rubber wheel 420, which has a certain damping effect.

[0041] The oil pressure spring shock absorber 200 and the support plate 310 are both arranged in an inclined manner, so that a triangular structure is formed between the support frame 300, the oil pressure spring shock absorber 200 and the bearing platform 100, that is, a triangular structure composite shock absorbing platform. The design of the triangular structure is compact, efficient and stable, which can reduce the volume of the entire shock absorbing platform, and at the same time, the stress of each part is more uniform, which helps to reduce structural fatigue and improve the overall performance of the system.

[0042] When the scooter is subjected to bumps and vibrations, effective buffering and shock absorption of the scooter can be achieved. Among them, the oil pressure spring shock absorber 200 can effectively reduce the impact force and vibration, and realize smooth damping through oil damping, thereby improving the stability and service life of the equipment.

[0043] In addition, the hub motor 400 is connected with the support frame 300 through an output shaft, realizing point contact, so that the vibration is effectively absorbed and isolated through the contact point, reducing the propagation of vibration.

[0044] In addition, the utility model still includes shock pad 500, shock pad 500 is located the support frame 300 below the bearing platform 100. Specifically, shock pad 500 is located the support plate 310 below, and is close to the connecting end of support plate 310 and bearing platform 100. When the support rod 310 exists larger rotation, the secondary shock absorption and spacing function of shock pad 500 are provided.

[0045] The bearing platform 100 is also provided with uniformly distributed holes, which play a role in weight reduction.

[0046] The shock absorption principle of the utility model is:

[0047] When the scooter is carrying heavy objects, subjected to external impact or running in bumpy and complex sections, the shock absorption platform can efficiently relieve the vibration and impact from the outside through the synergistic effect of the oil spring shock absorber 200 and the point contact hub motor 400.

[0048] When the platform encounters changes in the weight of the load or external impact and bumps, the oil spring shock absorber 200 first absorbs the instantaneous impact from the ground through its hydraulic damping effect, converting the vibration energy into heat energy to reduce the amplitude and duration of vibration, providing stable shock absorption effect and ensuring smooth operation of the vehicle body in complex environments. At the same time, in close cooperation with the point contact hub motor 400, the shock absorption platform can still maintain smooth operation on uneven ground. The unique point contact design of the hub motor 400 effectively reduces friction, mechanical loss and vibration transmission and concentration, better disperses the impact force, so that the shock absorption platform can still maintain high efficiency in bumpy environments. The triangular support structure formed by the support frame 300, the oil spring shock absorber 200 and the bearing platform 100 can evenly distribute forces from all directions, while the buffer pad 500 further absorbs sudden impacts to ensure the stability and shock resistance of the platform in complex situations.

[0049] Each shock absorption component of the utility model closely cooperates with the overall system, thereby ensuring that the shock absorption platform can still efficiently disperse and absorb vibration even in extremely complex or extreme terrain conditions, providing a comfortable and stable user experience.

[0050] The utility model has the following advantages:

[0051] 1. Under the condition of loading dozens of kilograms or even hundreds of kilograms of equipment and supplies, while following the user walking in the wild environment, efficient shock absorption can be achieved, effectively protecting the goods and reducing damage caused by vibration.

[0052] 2. The triangular structure design ensures that the stress between each component is uniform, reducing the instability caused by uneven stress, improving the overall stability and seismic capacity of the system.

[0053] 3. The use of more effective oil spring shock absorber can quickly respond to external impact and provide better shock absorption effect, while maintaining relatively stable shock absorption performance at different temperatures and pressures, avoiding the influence of temperature change on shock absorption effect.

[0054] 4. The application of point contact hub motor avoids complex transmission system, so that the vibration is effectively isolated and absorbed in a smaller range, and the shock absorption platform can smoothly run on uneven terrain.

[0055] 5. The application of buffer pad, which is small in size, can play an instant buffering role when the platform is subjected to sudden large impact or collision, enhancing the overall effect of the shock absorption system.

[0056] The utility model discloses a shock absorption platform of motor cycle, which can be applied to the transportation of materials for combat troops and patrol troops, and is used for the shock absorption of emergency rescue equipment and material transport vehicles of armed police, earthquake, forest protection, flood prevention and the like.

[0057] The above-mentioned is only the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion using the content of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
