Through the arrangement of the first rotating shaft, the damping plate, the connecting end, the damper and other structures, when a rear wheel bumps and moves upwards, the rear portion of the bottom fork can be driven to move upwards, so that the front portion of the bottom fork and the first rotating shaft are driven to rotate, and the second end of the damping plate is driven to press the damper downwards; due to the fact that the internal structure of the shock absorber is provided with the spring and the damping system, the shock absorber can generate counter-acting force when being compressed, the counter-acting force acts on the bottom fork, and therefore the shock absorption effect of the bottom fork and the whole frame is achieved. And the whole shock absorber is hidden between the bottom fork and the frame body, so that the attractiveness is improved.

Description

Technical Field

[0001] This utility model belongs to the field of vehicle frame technology, and specifically relates to a vehicle frame. Background Technology

[0002] Electric vehicles are a convenient means of short-distance transportation. Existing frames on the market generally use a dual-shock system, which increases the overall weight of the frame and does not meet the needs of most users for a lightweight frame. Moreover, dual shock absorbers are mostly located under the seat, which affects the aesthetics. Therefore, we propose a frame design to solve the above problems. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a frame that solves the problems of dual shock absorbers increasing frame weight and affecting aesthetics due to their placement.

[0004] This utility model is achieved through the following solution: a vehicle frame, comprising:

[0005] A swingarm, the swingarm comprising a front portion and a rear portion for mounting a rear wheel;

[0006] The first pivot is fixed to the front part;

[0007] The frame is movably hinged to the front via the first pivot.

[0008] A connecting end fixed to the frame and located at the front of the front part;

[0009] A first end is fixed to a shock-absorbing plate at the front, the shock-absorbing plate being inclined upward relative to the front and facing the connecting end; and

[0010] The shock absorber has its first end hinged to the second end of the shock absorber plate and its second end hinged to the connecting end. The rear of the flat fork moves upward, causing the front and the first rotating shaft to rotate, thereby driving the second end of the shock absorber plate to press down on the shock absorber to achieve shock absorption.

[0011] A further improvement of the frame of this utility model is that the included angle between the shock absorber and the shock absorber plate is maintained at not less than 90 degrees during their relative movement.

[0012] A further improvement of the vehicle frame of this utility model is that the frame includes a main frame rod and two side frame rods respectively fixed on both sides of the main frame rod. The first end of the main frame rod is used to install the front wheel, and the connecting end is fixed to the second end of the main frame rod. The first rotating shaft is rotatably connected between the two side frame rods.

[0013] A further improvement of the frame of this utility model is that each of the side frame rods includes a side rod and a fixing lug, the side rod is fixedly connected to the side of the main frame rod, the fixing lug is fixed to the side rod, and the first rotating shaft is rotatably connected between the two fixing lugs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through its structure including a first rotating shaft, a shock-absorbing plate, a connecting end, and a shock absorber, allows the rear of the swingarm to move upward when the rear wheel encounters a bump. This, in turn, causes the front of the swingarm and the first rotating shaft to rotate, driving the second end of the shock-absorbing plate to press down on the shock absorber. Because the internal structure of the shock absorber includes a spring and a damping system, the shock absorber generates a reaction force when compressed, which acts on the swingarm, thus achieving a shock absorption effect for the swingarm and the entire frame. Furthermore, the entire shock absorber is hidden between the swingarm and the frame, improving aesthetics. Attached Figure Description

Detailed Implementation

[0023] To address the issues of dual shock absorbers increasing frame weight and affecting aesthetics due to their placement, this invention provides a new type of frame. The following description, in conjunction with specific embodiments and accompanying drawings, further illustrates this frame.

[0024] See Figures 1-6As shown, a frame includes:

[0025] The swingarm 2 includes a front section and a rear section for mounting the rear wheel 7;

[0026] The first rotating shaft 3 is fixed at the front.

[0027] The frame 1 is hinged to the front via the first pivot 3;

[0028] The connecting end 4 is fixed to the frame 1 and located at the front of the front part;

[0029] The first end is fixed to the front of the damping plate 6, which is inclined upward relative to the front and faces the connecting end 4; and

[0030] The shock absorber 5 has its first end hinged to the second end of the damping plate 6 and its second end hinged to the connecting end 4. The rear of the flat fork 2 moves upward, causing the front and the first rotating shaft 3 to rotate, thereby driving the second end of the damping plate 6 to press down on the shock absorber 5 to achieve shock absorption.

[0031] Specifically, the second end of the shock absorber 5 is hinged to the connecting end 4 via the second rotating shaft 401, and the first end of the shock absorber 5 is hinged to the second end of the shock absorber plate 6 via the third rotating shaft 601.

[0032] By adopting the above design, when the rear wheel 7 moves upward when encountering a bump, it will drive the rear part of the horizontal fork 2 to move upward along the upward direction 10 of the rear part of the horizontal fork, thereby driving the front part of the horizontal fork 2 and the first pivot 3 to rotate along the rotation direction 9 of the shock absorber plate, so as to drive the second end of the shock absorber plate 6 to press down on the shock absorber 5 along the downward pressing direction 8 of the shock absorber plate. Since the internal structure of the shock absorber 5 has a spring and a damping system, the shock absorber 5 will generate a reaction force when compressed, which acts on the horizontal fork 2, thereby achieving the shock absorption effect of the horizontal fork 2 and the entire frame; and the entire shock absorber 5 is hidden between the horizontal fork 2 and the frame 1, which improves the aesthetics.

[0033] The included angle between the shock absorber 5 and the shock absorber plate 6 is maintained at no less than 90 degrees during their relative movement.

[0034] By adopting the above design, vibration reduction can be better achieved, thus achieving the desired vibration reduction effect.

[0035] The frame 1 includes a main frame rod 102 and two side frame rods 101 fixed on both sides of the main frame rod 102. The first end of the main frame rod 102 is used to install the front wheel (not shown in the figure), the connecting end 4 is fixed to the second end of the main frame rod 102, and the first rotating shaft 3 is rotatably connected between the two side frame rods 101.

[0036] Each side frame rod 101 includes a side rod and a fixing lug 103. The side rod is fixedly connected to the side of the main frame rod 102, and the fixing lug 103 is fixed to the side rod. The first rotating shaft 3 is rotatably connected between the two fixing lugs 103.

[0037] Specifically, the end of the side frame rod 101 away from the main frame rod 102 is bent upward to form a support end, and a pad frame for mounting a seat cushion (not shown in the figure) is installed on the upper part of the support end.

[0038] By adopting the above design, it is beneficial for the horizontal fork 2 and the frame 1 to achieve a movable hinge. Combined with the shock absorber 6, the connecting end 4 and the shock absorber 5, the frame of this application has good shock absorption performance.
