[0033] Please refer toFigure 1 and Figure 2 The utility model provides a kind of shock absorption system 1 of electric balance car, including front wheel shock absorption component 10 and shock absorption component 11.Front wheel shock absorption component 10 includes support frame 12, one end of support frame 12 is connected with vertically arranged support rod, the middle part of support frame 12 is connected with vehicle body 101, support rod is connected with handle.Shock absorption component 11 includes shock absorber 111 and at least one rocker arm 112, shock absorber 111 is horizontally arranged.One end of shock absorber 111 is connected with the middle part of support frame 12, the other end of shock absorber 111 is connected with one end of rocker arm 112, the other end of rocker arm 112 is movably connected with the other end of support frame 12, and the end of the rocker arm away from the support rod is connected to wheel hub.

[0034] Support frame 12 is as the key component of connecting vehicle body 101, provides stable support for entire shock absorption system 1.It can transmit vibration from vehicle body 101 to shock absorption component 11, ensure that shock absorption component 11 can effectively play a role.The material of support frame 12 can be selected from one of aluminum alloy, magnesium alloy, plastic and carbon fiber.For example, the material of support frame 12 is aluminum alloy, which has excellent strength, can withstand certain pressure and impact, and is not easy to deform or damage in daily use.Aluminum alloy also has good corrosion resistance and is not prone to rust, so that it can maintain good appearance and performance even if used in a humid environment.In addition, it is light in weight, facilitating carrying and operation.This makes the overall weight of electric balance car reduce, and facilitates user to carry and use in different occasions.

[0035] Shock absorber 111 is horizontally arranged on front wheel shock absorption component, one end is connected with the middle part of support frame 12, and the other end is connected with rocker arm 112.When vehicle body 101 travels on uneven road section, vibration is transmitted to rocker arm 112 from wheel hub, and then transmitted to shock absorber 111, and shock absorber 111 performs telescopic movement to generate damping effect, slow down the amplitude of vibration of vehicle body 101, and improve the comfort of riding.

[0036] In prior art electric balance car, rocker arm is directly connected on both sides of vehicle body by shaft pin or bolt.Rocker arm one end is connected with wheel hub of vehicle wheel, and the other end is connected with support rod, and connection point is usually at low position on side surface of vehicle body, close to the height of vehicle wheel.This straight connection type rocker arm extends downward along the angle of support rod to connect wheel hub, so that the distance between vehicle wheel and central axis of vehicle body becomes longer, resulting in that the overall length of electric balance car also becomes longer.

[0037] The rocker arm 112 is independently connected to the support frame 12, the shock absorber 111 and the wheel hub, does not depend on the design of the support rod, can connect the rocker arm 112 to one end of the wheel hub close to the vehicle body, realizes the compact layout between the rocker arm 112, the wheel and the damping system, shortens the distance between the wheel and the vehicle body 101, and reduces the overall length of the electric balance car.

[0038] The rocker arm 112 is movably connected to the support frame 12, so that the rocker arm 112 can freely move within a certain range. In some embodiments, the rocker arm 112 is rotatably connected to the support frame 12. When the vehicle body 101 encounters a shock, the rocker arm 112 can rotate according to the direction and amplitude of the shock, so as to transmit the shock to the shock absorber 111. Of course, the above is only exemplary, and the specific movement mode of the rocker arm 112 can be designed according to actual needs, and the utility model does not make any limitation here.

[0039] The damping system 1 provided by the utility model has the advantages that:

[0040] (1) The movable connection of the rocker arm 112 and the support frame 12 makes the damping system 1 more flexible to adapt to shocks in different directions and degrees, thereby greatly reducing the shock amplitude transmitted to the vehicle body 101 and the rider. This makes the rider feel more stable and comfortable during driving, and reduces fatigue and discomfort caused by shocks.

[0041] (2) The shock absorber 111 is horizontally arranged on the vehicle body 101, and the rocker arm 112 is connected to the shock absorber 111, the support frame 12 and the wheel hub, so that the distance of the wheel hub relative to the central axis of the vehicle body 101 is shortened, the length of the electric balance car is shortened as a whole, and the packaging and transportation of the finished product are facilitated.

[0042] Please refer to Figure 3 In order to reduce the shock and impact of the above-mentioned uneven road on the vehicle body 101, the shock absorber 111 comprises a damper 1111 and an elastic member 1112 connected with the damper 1111. The elastic member 1112 can generate elastic force when the support frame 12 is pressed, and drive at least one rocker arm 112 to reset through the elastic force. The damper 1111 can consume part of the elastic force.

[0043] The damper 1111 is one of the core components of the shock absorber 111, and one end of the damper 1111 is connected to the rocker arm 112, and the other end is connected to the support frame 12. When the vehicle body 101 vibrates, the rocker arm 112 moves relative to the support frame 12, and the elastic member 1112 is compressed when the support frame 12 is pressed, thereby storing the above-mentioned energy as elastic force. However, the elastic member 1112 stores too much elastic force, which will affect the ride comfort and handling stability of the electric balance car, and the damper 1111 needs to consume part of the energy through its damping action. The rocker arm 112 applies pressure to the damper 1111 in the direction of the support frame 12, so that the telescopic rod of the damper 1111 retracts. When the elastic member 1112 is reset from the compressed state, the elastic member 1112 drives the telescopic rod of the damper 1111 to extend, at which time the damper 1111 consumes part of the elastic force of the elastic member 1112, which can avoid the impact on the vehicle body 101 caused by excessive elastic force, and can also reduce the transmission of vibration and improve the riding comfort.

[0044] In some embodiments, the damper 1111 is one of a hydraulic damper 1111, an air damper 1111 and an electromagnetic damper 1111. For example, the damper 1111 is a hydraulic damper 1111, and the elastic member 1112 is sleeved on the outer surface thereof. It is a vibration control device that is sensitive to displacement, which can effectively control vibrations and oscillations of various frequencies in cooperation with the elastic member 1112, thereby improving the driving comfort of the driver. It should be noted that the hydraulic damper 1111 is a prior art, and its working principle will not be described here.

[0045] It should be noted that the elastic member 1112 can be a spring. Of course, the above is only exemplary, and the specific can be determined according to actual needs, and the utility model is not limited herein.

[0046] Please refer to Figure 2 In the present embodiment, the rocker arm 112 is V-shaped, wherein the tip of the V-shaped is defined as the first end 1123, and the two ends away from the tip are respectively the second end 1122 and the third end 1121, the first end 1123 is connected to the other end of the support frame 12, the second end 1122 is connected to the shock absorber 111, and the third end 1121 is used to connect the hub.

[0047] The rocker arm 112 of the present embodiment is integrally formed, so that the connection between the first end 1123, the second end 1122 and the third end 1121 is more firm and reliable. During the driving of the electric balance car, the rocker arm 112 will bear various vibrations and stresses from the vehicle body 101. If the connection part is not firm enough, problems such as loosening and breaking are likely to occur, which will affect the normal work of the shock absorbing system 1. The integrally formed structure can effectively avoid these problems and improve the overall strength and stability of the rocker arm 112.

[0048] The rocker arm 112 is arranged in a horizontal V-shape on the front wheel damping assembly 10, which can better adapt to vibrations and stresses in different directions during operation. When the vehicle body 101 encounters bumps, the V-shaped structure allows the rocker arm 112 to swing flexibly in different directions, effectively transmitting and dispersing vibration energy. In addition, the horizontal V-shaped design of the rocker arm 112 makes the connection between the rocker arm 112 and the hub closer to the center axis of the vehicle body 101, thereby making the wheel closer to the vehicle body 101 and reducing the overall length of the vehicle, facilitating packaging and transportation of the finished vehicle.

[0049] Specifically, the first end 1123 is movably connected to the support frame 12, allowing the rocker arm 112 to swing freely on the support frame 12. This type of movable connection usually uses hinges, bearings, or ball joints as connecting components to ensure the flexibility and stability of the rocker arm 112.

[0050] The second end 1122 is connected to the shock absorber 111, transmitting the swing of the rocker arm 112 to the shock absorber 111 to ensure that the shock absorber 111 can effectively receive and process the vibration energy transmitted by the rocker arm 112. When the rocker arm 112 swings, the second end 1122 pushes the shock absorber 111 to extend and contract, causing the shock absorber 111 to generate damping action to absorb and dissipate vibration energy. The feedback force of the shock absorber 111 is also transmitted to the rocker arm 112 through the second end 1122, allowing the rocker arm 112 to quickly return to its original position after the vibration. This cooperative relationship ensures that the damping system 1 is always in the best working condition, providing a smooth and comfortable riding experience for the rider.

[0051] The third end 1121 is connected to the hub, responsible for transmitting the vibration generated by the impact on the hub to the rocker arm 112. In some embodiments, the third end 1121 is connected to the hub in a detachable manner. When the third end 1121 of the rocker arm 112 or the wheel is damaged or malfunctioning, it can be easily detached from the vehicle body 101 for repair or replacement without the need for extensive disassembly of the entire vehicle body 101. This greatly reduces the difficulty and cost of maintenance and saves maintenance time.

[0052] In some embodiments, the damping assembly 11 includes two rocker arms 112, which are arranged on opposite sides of the shock absorber 111.

[0053] First, the arrangement of two rocker arms 112 can provide more stable support for the shock absorber 111. When the vehicle body 101 encounters bumps or vibrations during operation, the two rocker arms 112 can jointly share forces from different directions, thereby reducing the pressure on a single rocker arm 112 and improving the stability of the entire damping system 1.

[0054] Secondly, two swing arms 112 are arranged on opposite sides of the shock absorber 111, so that the swing arms 112 can more balancedly transmit and disperse the shock energy during work. This symmetrical layout can effectively prevent the shock absorber 111 from tilting or deviating during work, ensuring the consistency and reliability of the damping effect. For example, when the vehicle body 101 is subjected to shock in the horizontal direction, the swing arms 112 on both sides of the shock absorber 111 can simultaneously press the shock absorber 111 in the middle to absorb and disperse the shock energy; when the vehicle body 101 is subjected to shock in the vertical direction, the swing arms 112 can relieve the shock by swinging up and down. This multi-directional damping effect can effectively reduce the sway and jolt of the vehicle body 101, improving the stability and comfort of riding.

[0055] Finally, the design of the two swing arms 112 can improve the reliability of the damping assembly 11. In actual use, if one of the swing arms 112 fails or is damaged, the other swing arm 112 can still continue to work, thereby ensuring the normal operation of the damping system 1. This redundant design can effectively reduce the risk of failure of the entire damping system 1 due to the failure of a single component, improving the reliability and safety of the electric balance car.

[0056] Please refer to Figure 4 In some embodiments, the damping system 1 of the electric balance car further includes a rear wheel damping device 13, which includes the damping assembly 11 described above. It can be understood that the damping assembly 11 is arranged at both ends of the electric balance car to dampen the vehicle body 101.

[0057] Firstly, by arranging the rear wheel damping device 13, the shock energy at the rear end of the electric balance car can be more effectively absorbed and dispersed. When the vehicle body 101 encounters bumps, uneven road surfaces or other impacts during driving, the damping assembly 11 at the front end of the electric balance car and the rear wheel damping device 13 can both play a certain damping role, thereby greatly enhancing the overall damping performance.

[0058] Secondly, two damping assemblies 11 are arranged side by side and spaced apart at both ends of the electric balance car, so that the stress on both ends of the vehicle body 101 is more uniform. Whether in straight driving or turning, each damping assembly 11 can share the weight and shock of the vehicle body 101 according to the actual situation, avoiding damage or instability caused by excessive local stress.

[0059] Finally, for various complex road conditions, the double damping assemblies 11 can better stabilize the vehicle body and reduce the sway and jolt of the vehicle during driving. Whether it is a small amplitude shock or a larger impact, the rider can better control the driving direction and speed of the vehicle and maintain the balance of the vehicle body 101, improving the maneuverability and stability of the vehicle.

[0060] Please refer to Figure 3 and Figure 8 In some embodiments, the second ends 1122 of the two swing arms 112 are connected by a first connecting shaft 113, and the shock absorber 111 is rotationally connected to the first connecting shaft 113.

[0061] The two swing arms 112 are collectively connected to the first connecting shaft 113, and the stress is evenly distributed at both ends, so that the local stress of one swing arm 112 does not cause damage. Not only does it improve the service life of the shock absorbing assembly 11, but also improves the stability of the shock absorbing assembly 11, ensuring that the electric balance car can run smoothly on various road conditions and improve the comfort of the driver.

[0062] The shock absorber 111 is rotationally connected to the first connecting shaft 113, and when the vehicle body 101 vibrates, the swing arm 112 swings with the lifting of the wheels. The shock absorber 111 connected to the swing arm 112 adjusts its angle by rotating through the first connecting shaft 113 to adapt to the lifting of the wheels. At the same time, the swing arm 112 pushes the damper 1111 and the elastic member 1112 against the support frame 12, and the damper 1111 and the elastic member 1112 are compressed to consume the energy of the vibration and slow down the vibration of the vehicle body 101, so that the driver can drive smoothly.

[0063] Please refer to Figures 4 to 8 In this embodiment, the other end of the support frame 12 is provided with a through hole 1211, and the through hole 1211 is provided with a second connecting shaft 1212, and the swing arm 112 is rotationally connected to the second connecting shaft 1212.

[0064] The second connecting shaft 1212 is provided in the through hole 1211 at the lower end of the support frame 12, and the swing arm 112 is rotationally connected to the support frame 12 through the second connecting shaft 1212. This connection allows the swing arm 112 to rotate freely within a certain range and to adapt to different road conditions and vibration conditions. When the vehicle is driving on uneven road surfaces, the swing arm 112 can rotate around the second connecting shaft 1212, and the shock absorber 111 can absorb and buffer the vibration, improving the comfort of riding.

[0065] Please continue to refer to Figures 4 to 8 In this embodiment, the through hole 1211 is provided with a bearing mounting step 123 and a buffer 124, and the buffer 124 is annularly arranged at the bearing mounting step 123 to absorb the vibration energy generated when the swing arm 112 rotates.

[0066] In one aspect, the buffer 124 is annularly arranged at the bearing mounting step 123, which can effectively absorb the vibration energy generated when the rocker arm 112 rotates. When the rocker arm 112 rotates on the second connecting shaft 1212, certain vibrations will inevitably be generated, and if not controlled, these vibrations will be transmitted to the vehicle body 101, affecting the comfort and stability of riding. The presence of the buffer 124 can absorb and disperse these vibration energies, reducing the impact on the vehicle body 101.

[0067] On the other hand, the buffer 124 can play a role in protecting the connection site. The rotation of the rocker arm 112 will generate certain friction and wear on the second connecting shaft 1212 and the through hole 1211, and the buffer 124 can reduce this friction and wear, prolonging the service life of the connection site.

[0068] Among them, the bearing mounting step 123 provides a stable mounting position for the buffer 124, ensuring that the buffer 124 can be accurately mounted at the through hole. This can ensure that the buffer 124 does not displace or fall off during operation, and always plays its role in absorbing vibration energy. In addition, the design of the bearing mounting step 123 also makes it easier to install and replace the buffer 124. When installing the buffer 124, the second connecting shaft 1212 can be installed first, and then the buffer 124 can be accurately placed on the bearing mounting step 123. When the buffer 124 needs to be replaced, the buffer 124 can also be easily removed from the bearing mounting step 123 for replacement operation.

[0069] It should be noted that the buffer 124 is a rubber shock pad. Of course, the above is only exemplary, and the specific type of buffer 124 can be determined according to actual needs, and the present utility model does not limit it.

[0070] The utility model also proposes a kind of electric balance car, including vehicle body 101 and the shock-absorbing system 1 of electric balance car as described above.

[0071] It should be noted that since the electric balance car adopts all the technical solutions of the above shock-absorbing system 1, the electric scooter of the present utility model also has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0072] The above is only part or preferred embodiment of the present utility model, neither text nor drawings can limit the scope of protection of the present utility model, equivalent structural transformation using the contents of the utility model specification and drawings, or direct / indirect application in other related technical fields are included in the scope of protection of the present utility model under the concept of the whole of the present utility model.
