Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle frame technology, and in particular to an electric vehicle frame shock absorption mechanism. Background Technology
[0002] The frame of an electric vehicle is its skeletal structure. It's the fundamental component that supports and secures all the other parts of the vehicle, much like the skeleton of the human body, playing a crucial role in load-bearing. The frame's main function is to secure numerous components such as the motor, battery, controller, handlebars, and wheels in a rational layout and position, enabling them to work together effectively.
[0003] Existing electric vehicles have some shortcomings in use. When riding on rough roads, electric vehicles are prone to shaking and other dangers to the driver. Existing electric vehicles only rely on shock-absorbing springs above the wheels for cushioning, which is not effective. When encountering steep roads, this not only provides a bad experience for the driver but also easily causes shaking, leading to falls and reducing the lifespan of the electric vehicle. To address these issues, an improved and upgraded shock absorption mechanism for the electric vehicle frame is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a shock absorption mechanism for an electric vehicle frame to solve the problems mentioned in the background art.
[0005] To solve the above problems, the following technical solutions are provided:
[0006] Design an electric vehicle frame shock absorption mechanism, including a main frame, a battery box installed inside the main frame, and a base frame fixedly connected to the bottom of the main frame. Two sets of first hinge seats and second hinge seats are fixedly installed on the outer sides of the main frame and the base frame, respectively. A buffer spring is movably connected between the first hinge seats and the second hinge seats. The buffer spring is sleeved on the outside of the shock absorber and the piston rod. Two fixed rods are fixedly installed inside the base frame, and two guide blocks are fixedly and symmetrically installed on the outer wall of each fixed rod. A shock absorption component is installed below the base frame.
[0007] Furthermore, the shock absorption assembly includes a support frame, a limiting frame, and a connecting plate. The support frame is fixedly installed inside the electric vehicle, and two sets of limiting frames are provided on the upper surface of the support frame. The two sets of limiting frames are of the same size.
[0008] Furthermore, a connecting plate is fixedly connected to the outer wall of the support frame, and a sleeve is fixedly installed at one end of the connecting plate. A damping rod is installed inside the sleeve, and a return spring is sleeved on the outside of the damping rod.
[0009] Furthermore, the sleeve is located below the main frame, the damping rod and the internal groove of the sleeve are matched in size, and the four limiting brackets are all fixedly installed on the upper end of the support frame.
[0010] Furthermore, each of the four limiting frames has a cavity inside, and a guide frame is provided inside the cavity. The upper surface of the limiting frame has an insertion hole, and a guide post is provided inside the insertion hole.
[0011] Furthermore, dampers are provided on both sides inside the guide frame, and shock-absorbing springs are sleeved on the outside of the dampers. The guide post passes through the insertion hole and its extension end is connected to the damper. The internal dimensions of the guide frame are adapted to the diameter of the guide block.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model device includes components such as a first hinge seat, a buffer spring, a support frame, a limit frame, a guide frame, a sleeve, a return spring, and a shock-absorbing spring. The buffer spring between the first and second hinge seats on the electric vehicle frame works in conjunction with the device. Then, the base frame drives the guide blocks on the two fixed rods to apply downward pressure, causing the four guide blocks to press against the guide frame on the limit frame for buffering. The guide frame is then compressed by dampers on both sides, and the shock-absorbing springs work together to disperse the pressure from above. Simultaneously, the pressure on the front of the main frame is compressed downward by the damping rod inside the compression sleeve, and then buffered by the return spring. This provides dual shock absorption and buffering for the electric vehicle frame, protecting it while improving driver comfort and increasing the electric vehicle's lifespan. The structure is simple.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1 - Figure 5 As shown in the figure, this embodiment provides a shock absorption mechanism for an electric vehicle frame, including a main frame 1, a battery box 2 installed inside the main frame 1, and a base frame 3 fixedly connected to the bottom of the main frame 1. Two sets of first hinge seats 4 and second hinge seats 6 are fixedly installed on the outer sides of the main frame 1 and the base frame 3, respectively. A buffer spring 5 is movably connected between the first hinge seat 4 and the second hinge seat 6. The buffer spring 5 is sleeved on the outer side of the shock absorber and the piston rod. Two fixed rods 8 are fixedly installed inside the base frame 3, and two guide blocks 9 are fixedly and symmetrically installed on the outer wall of each fixed rod 8. A shock absorption component 7 is installed below the base frame 3.
[0024] Preferably, the shock absorption assembly 7 includes a support frame 71, a limiting frame 72, and a connecting plate 73. The support frame 71 is fixedly installed inside the electric vehicle, and two sets of limiting frames 72 are provided on the upper surface of the support frame 71. The two sets of limiting frames 72 are the same size. The connecting plate 73 is fixedly connected to the outer wall of the support frame 71, and a sleeve 74 is fixedly installed at one end of the connecting plate 73. A damping rod 741 is provided inside the sleeve 74, and a return spring 742 is sleeved on the outside of the damping rod 741. The sleeve 74 is located below the main frame 1. The internal slot size of the damping rod 741 and the sleeve 74 are compatible to facilitate the stable assembly of the damping rod 741. All four limiting frames 72 are fixedly installed on the upper end of the support frame 71.
[0025] Preferably, each of the four limiting frames 72 has a cavity 75 inside, and a guide frame 76 is installed inside the cavity 75. The upper end face of the limiting frame 72 has an insertion hole, and a guide post 77 is installed inside the insertion hole. Both sides of the guide frame 76 are provided with dampers 79, and shock-absorbing springs 78 are sleeved on the outside of the dampers 79, so as to buffer the guide block 9 when it is pressed down, and to provide buffer protection for the electric vehicle frame. The guide post 77 passes through the insertion hole and its extension end is connected to the damper 79. The internal dimensions of the guide frame 76 are adapted to the diameter of the guide block 9.
[0026] The working principle and process of this utility model are as follows: First, when the electric vehicle encounters a rough road, the wheels of the electric vehicle cause a bumpy ride. The electric vehicle frame 1 is compressed by the shock absorber inside the buffer spring 5 on the first hinge seat 4. The shock absorber then buffers the pressure through the second hinge seat 6, thus cushioning the electric vehicle frame and wheels and reducing shaking. At the same time, the base frame 3 below the main frame 1 drives the guide blocks 9 on the two fixed rods 8 to apply downward pressure. The four guide blocks 9 press against the guide frame 76 on the limit frame 72 for cushioning. Then, the pressure above is dispersed by the compression dampers 79 on both sides of the guide frame 76 and the shock absorber springs 78 working together. Meanwhile, the pressure on the front side of the main frame is compressed downward by the damping rod 741 inside the compression sleeve 74 and then buffered by the return spring 742. The pressure on the main frame 1 is dispersed to the support frame 71, which can provide double shock absorption and cushioning for the electric vehicle frame, thus protecting the frame.
