Description

Technical Field

[0001] This utility model relates to the field of vehicle frame technology, and in particular to an electric vehicle frame. Background Technology

[0002] The electric vehicle frame is the core supporting structure of the entire vehicle, equivalent to the vehicle's "skeleton system," and its design directly affects safety, stability, and durability.

[0003] When assembling existing electric vehicles, all components are sequentially installed on the frame. The high strength of the frame is used to support the weight of all components, such as the battery, motor, and controller, and to distribute the impact force during driving.

[0004] However, since existing electric vehicles can generally only adjust the height of the seat and not the distance between the seat and the handlebars laterally, it may cause some people with shorter arms to be too far from the handlebars, resulting in the rider being in a forward or prone position, which affects the rider's normal riding and riding safety. Utility Model Content

[0005] The technical problem this utility model aims to solve is that existing electric vehicles can generally only adjust the height of the seat, but cannot adjust the distance between the seat and the handlebars laterally. This may result in some people with shorter arms being too far from the handlebars, causing them to be in a forward-leaning or prone position while riding, affecting their normal riding and riding safety.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an electric vehicle frame, comprising: a frame body, which serves as a supporting structure for the overall components of the electric vehicle; a seat, which is installed on the frame body to provide a sitting area for a person; and an adjustment device, which is disposed between the frame body and the seat and is used to adjust the distance between the seat and the handlebars and the angle of the seat.

[0007] Preferably, the adjusting device includes: a hole frame fixedly connected to the frame body; a slide block slidably mounted on the hole frame, wherein a spring pin is slidably connected to the inner wall of the slide block, wherein one end of the spring pin is fixedly connected to the slide block, wherein the spring pin is fixed to the slide block by inserting into the hole of the hole frame, wherein the spring pin is made of magnetically attractive metal; an axle bracket fixedly connected to the slide block, wherein the axle bracket has a hole; and a connecting block fixedly connected to the frame body, wherein the connecting block is rotatably mounted on the axle bracket, wherein the connecting block has multiple threaded holes, wherein bolts are threaded into the threaded holes, and wherein the connecting block is placed on the axle bracket and fixed by bolts.

[0008] The effect achieved by the above components is as follows: By setting the adjustment device, firstly, the seat is manually rotated, causing the seat to drive the connecting block to rotate inside the axle frame. When the seat rotates to the specified angle position, the inner wall of any threaded hole on the connecting block coincides with the inner wall of the hole on the axle frame. At this time, the bolt is manually screwed into the axle frame and the connecting block to fix the connecting block and the seat, completing the angle adjustment of the seat. Then, the spring pin is manually pulled out of the hole frame and the seat is moved left and right, causing the seat to drive the slide to move left and right along the hole frame through the connecting block and the axle frame. This causes the slide to drive the spring pin to move. When the seat is moved to the designated position, the spring pin aligns with any hole on the hole frame. Releasing the hand that pulled the spring pin causes it to move closer to the hole frame due to the spring's reaction force. This allows the spring pin to be inserted into the hole frame and the slide block, thus fixing the slide block in place. This achieves lateral adjustment of the seat, reducing the distance between the seat and handlebars for riders with shorter arms, preventing them from being in a forward-leaning or prone position, which affects riding safety and normal function. It also improves the seat's flexibility.

[0009] Preferably, one end of the bolt is fixedly connected to a screw block, wherein the surface of the screw block is provided with multiple protrusions.

[0010] The effect achieved by the above-mentioned components is that by setting the screwing block, the contact area between the hand and the bolt can be increased, thereby improving the convenience and stability of manually turning the bolt.

[0011] Preferably, a limiting rod is fixedly connected to the inner wall of the hole frame, wherein the limiting rod is placed in the groove of the slide to limit its movement, and both the limiting rod and the groove on the slide have a T-shaped cross-section.

[0012] The effect achieved by the above components is that by setting a limiting rod, the limiting rod can be placed inside the groove opened on the slide to limit the slide and reduce the wobbling of the slide during movement or use.

[0013] Preferably, a plurality of magnet blocks are fixedly connected to one side of the hole frame, wherein the magnet blocks correspond to the positions of the holes in the hole frame, and the magnet blocks are further fixed by adsorption spring pins.

[0014] The effect achieved by the above components is as follows: by setting up a magnet, when the pin is fully inserted into the hole frame, the magnet attracts the spring pin to assist in limiting its movement, thereby reducing the possibility of the spring pin shaking.

[0015] Preferably, a support plate is fixedly connected to one side of the hole frame, wherein the support plate is fixedly connected to the vehicle frame body.

[0016] The effect achieved by the above components is that by setting up a support plate, the side of the hole frame away from the frame body can be supported, thereby improving the stability of the hole frame and reducing the tilting or swaying of the hole frame away from the frame body after being subjected to force.

[0017] Preferably, it further includes: a storage component, the storage component including: a cylinder, the cylinder being fixed to the frame body, wherein the cylinder has a rectangular hole; and rubber blocks, wherein multiple rubber blocks are evenly arranged in a circumferential pattern and fixed inside the cylinder, wherein the surface of the rubber blocks has multiple protrusions.

[0018] The effect achieved by the above-mentioned components is as follows: By setting up a storage component, when a person needs to place a water cup, they can manually insert the water cup into the cylinder. This causes multiple rubber blocks inside the cylinder to deform under pressure, and the elastic restoring action of the rubber blocks compresses the surface of the water cup. At the same time, the multiple protrusions on the surface of the rubber blocks increase the friction with the surface of the water cup, thereby achieving the storage and fixation of the water cup. This reduces the situation where there is nowhere to put the water cup, which leads to the person having to hold the water cup while riding, affecting the riding safety, and improves the convenience of the person riding.

[0019] Preferably, a bracket is fixedly connected to the inner wall of the cylinder, wherein the cross-section of the bracket is T-shaped.

[0020] The effect achieved by the above components is that the bracket can intercept and support the water cup, so that there is a certain gap between the bottom of the water cup and the inner wall of the cylinder, making it convenient for people to take out the shorter water cup from inside the cylinder.

[0021] The beneficial effects of this utility model are:

[0022] The adjustable device allows for adjustment of the lateral distance between the saddle and handlebars, as well as the change of the saddle's vertical angle. This reduces the distance between the saddle and handlebars for riders with shorter arms, preventing them from being in a forward-leaning or prone position while riding, which could affect their riding safety and improve the saddle's usability.

[0032] Figure 1-5 The electric vehicle frame shown includes: a frame body 1, which serves as a supporting structure for the overall components of the electric vehicle; a seat 2, which is mounted on the frame body 1 and provides a seating area for a person; and an adjustment device 3, which is disposed between the frame body 1 and the seat 2 and is used to adjust the distance between the seat 2 and the handlebars and the angle of the seat 2.

[0033] Figure 2 , Figure 3 and Figure 4The adjustment device 3 shown includes: a hole frame 31, which is fixedly connected to the frame body 1; a slide 35, which is slidably mounted on the hole frame 31, wherein a spring pin 36 is slidably connected to the inner wall of the slide 35, wherein one end of the spring in the spring pin 36 is fixedly connected to the slide 35, wherein the spring pin 36 fixes the slide 35 by inserting into the hole in the hole frame 31, wherein the spring pin 36 is made of magnetically attractable metal; an axle bracket 37, which is fixedly connected to the slide 35, wherein the axle bracket 37 has a hole; and a connecting... Connecting block 38 is fixedly connected to the seat 2. Connecting block 38 is rotatably mounted on the axle bracket 37. Connecting block 38 has multiple threaded holes, each with a bolt 39 threaded into it. Connecting block 38 is fixed to the axle bracket 37 by the bolts 39. By setting the adjustment device 3, the seat 2 is first manually rotated, causing the seat 2 to drive the connecting block 38 to rotate along the inside of the axle bracket 37. When the seat 2 rotates to a specified angle position, the inner wall of any threaded hole on the connecting block 38 aligns with the inner wall of a hole on the axle bracket 37. When the positions coincide, manually screw bolt 39 into the shaft bracket 37 and connecting block 38 to fix the connecting block 38 and seat 2, completing the angle adjustment of seat 2. Then, manually pull spring pin 36 out of the hole frame 31 and move seat 2 left and right. This causes seat 2 to drive slide 35 to move left and right along the inside of hole frame 31 via connecting block 38 and shaft bracket 37, causing slide 35 to drive spring pin 36 to move. When seat 2 moves to the designated position, aligning spring pin 36 with any hole in hole frame 31, then release the bolt. The hand that moves the spring pin 36 moves it towards the hole frame 31 under the reaction force of the spring in the spring pin 36. This moves the spring pin 36 to a position where it is inserted into the hole frame 31 and the slide 35 to fix the slide 35. This achieves lateral adjustment of the seat 2, reducing the distance between the rider with shorter arms and the handlebars, which can cause the rider to be in a forward or prone position while riding, affecting the rider's normal riding and riding safety. This improves the usability of the seat 2.

[0034] Figure 2 , Figure 3 and Figure 4 One end of the bolt 39 shown is fixedly connected to a screwing block 310. The surface of the screwing block 310 is provided with multiple protrusions. By setting the screwing block 310, the contact area between the hand and the bolt 39 can be increased, improving the convenience and stability of manually turning the bolt 39. The inner wall of the hole frame 31 is fixedly connected to a limiting rod 32. The limiting rod 32 is placed in the groove of the slide 35 to limit its movement. The cross-section of the limiting rod 32 and the groove on the slide 35 are both T-shaped. By setting the limiting rod 32, the limiting rod 32 can be placed inside the groove on the slide 35 to limit the movement of the slide 35 and reduce the shaking of the slide 35 during movement or use.

[0035] Figure 2 , Figure 3 and Figure 4 Multiple magnet blocks 33 are fixedly connected to one side of the hole frame 31 shown. The magnet blocks 33 correspond to the hole positions of the hole frame 31. The magnet blocks 33 are assisted in fixing by adsorbing spring pins 36. By setting the magnet blocks 33, when the pin is fully inserted into the hole frame 31, the magnet blocks 33 are assisted in limiting the spring pins 36 by adsorbing them, reducing the possibility of the spring pins 36 shaking. A support plate 34 is fixedly connected to one side of the hole frame 31. The support plate 34 is fixedly connected to the frame body 1. By setting the support plate 34, the side of the hole frame 31 away from the frame body 1 can be supported, improving the stability of the hole frame 31 and reducing the possibility of the hole frame 31 tilting or shaking when subjected to force on the side away from the frame body 1.

[0036] Figure 5 The system also includes a storage component 4, which comprises a cylinder 41 fixed to the frame body 1, wherein the cylinder 41 has a rectangular hole; and rubber blocks 42, wherein multiple rubber blocks 42 are evenly arranged in a circular pattern and fixed inside the cylinder 41, wherein the surface of the rubber blocks 42 has multiple protrusions. By setting up the storage component 4, when a person needs to place a water cup, they can manually insert the water cup into the cylinder 41, causing the multiple rubber blocks 42 inside the cylinder 41 to deform under pressure, and under the elastic restoring action of the rubber blocks 42, the surface of the water cup is squeezed. At the same time, the multiple protrusions on the surface of the rubber blocks 42 increase the friction with the surface of the water cup, thereby achieving the storage and fixation of the water cup, reducing the situation where there is nowhere to put the water cup, causing the person to have to hold the water cup while riding, which affects the riding safety, and improving the convenience of the person riding.

[0037] Figure 5 The inner wall of the cylinder 41 shown is fixedly connected to a bracket 43, wherein the cross-section of the bracket 43 is T-shaped. By setting the bracket 43, the water cup can be intercepted and supported, so that there is a certain gap between the bottom of the water cup and the inner wall of the cylinder 41, making it convenient for people to take out the shorter water cup from the inside of the cylinder 41.

[0038] Working principle: First, manually rotate the seat 2, causing the connecting block 38 to rotate along the inside of the shaft bracket 37. When the seat 2 rotates to the specified angle position, the inner wall of any threaded hole on the connecting block 38 coincides with the inner wall of the hole on the shaft bracket 37. At this time, manually screw the bolt 39 into the shaft bracket 37 and the connecting block 38 to fix the connecting block 38 and the seat 2, completing the angle adjustment of the seat 2. Then, manually pull the spring pin 36 out of the hole frame 31 and move the seat 2 left and right, so that the seat 2 passes through the connecting block 38 and the shaft... The frame 37 drives the slide 35 to move left and right along the inside of the hole frame 31, causing the slide 35 to move the spring pin 36. When the seat 2 moves to the designated position, the spring pin 36 corresponds to any hole on the hole frame 31. At this time, the hand pulling the spring pin 36 is released. Under the reaction force of the spring in the spring pin 36, the spring pin 36 moves towards the hole frame 31, so that the spring pin 36 moves to the position of inserting into the hole frame 31 and the slide 35 to fix the slide 35, thereby achieving the lateral adjustment of the seat 2.

[0039] When a person needs to place a water cup, they manually insert the water cup into the cylinder 41. This causes the multiple rubber blocks 42 inside the cylinder 41 to deform under pressure. Under the elastic restoring action of the rubber blocks 42, the surface of the water cup is compressed. At the same time, the multiple protrusions on the surface of the rubber blocks 42 increase the friction with the surface of the water cup, thereby achieving the purpose of storing and fixing the water cup.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
