Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to a shock-absorbing foldable lithium battery electric bicycle. Background Art

[0002] Folding e-bikes are foldable electric bicycles that combine portability with environmental friendliness and energy efficiency, satisfying the modern urban dweller's pursuit of convenience and efficiency. Their unique design allows them to be folded down to a significantly smaller size, making them easy to store and carry. Designed to address the space constraints of urban life, folding e-bikes allow users to easily carry them into their homes, offices, or on public transportation.

[0003] The existing foldable lithium battery electric bicycle is provided with a foldable frame that can be folded and carried, and the fork of the electric bicycle is provided with a shock-absorbing structure to reduce shock during exercise. However, the seat of the electric bicycle is fixed in a hard connection. When the electric bicycle encounters bumps on the road, the seat cannot provide effective shock absorption, causing the rider's buttocks to feel uncomfortable due to bumps and vibrations. Therefore, we propose a shock-absorbing foldable lithium battery electric bicycle. Utility Model Content

[0004] The main purpose of the utility model is to provide a shock-absorbing foldable lithium battery electric bicycle. After a straight-insertion tube is set at the seat tube of the electric bicycle body, the straight-insertion tube is used to install a shock-absorbing mechanism. When the electric bicycle body encounters bumpy road conditions, the insertion tube of the shock-absorbing mechanism under the seat is lowered in a linear friction buffering manner at the straight-insertion tube with the help of a rubber ring pad. Then, the damper cooperates with the spring to form an elastic damping support in the straight-insertion tube, thereby reducing the vibration transmitted from the electric bicycle body to the seat, so that the rider sitting on the seat is less likely to feel discomfort when encountering bumpy and vibrating road conditions, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A shock-absorbing foldable lithium battery electric bicycle comprises an electric bicycle body and a seat tube, wherein the seat tube is fixed to the frame of the electric bicycle body, and the bicycle body further comprises a straight insert tube and a shock-absorbing mechanism, wherein the straight insert tube is inserted and clamped in the seat tube, and the shock-absorbing mechanism comprises an adhesive pad, a damper, a spring, a screw-on hole, a screw, a connecting disk, a plug tube, a rubber ring pad and a seat, wherein the damper is inserted into the inner tube wall of the straight insert tube, and the adhesive pad is bonded between the bottom of the damper and the inner tube wall of the straight insert tube, the telescopic rod of the damper is externally clamped with a spring, and the telescopic rod head of the damper is provided with a screw-on hole for screwing the screw, the screw is welded to the outside of the bottom tube mouth of the plug tube through the connecting disk, and the upper end tube body of the plug tube is fixed to the lower frame of the seat body of the seat, and the outer tube wall of the plug tube is clamped and bonded with a rubber ring pad.

[0007] Furthermore, the outer shell of the damper is annularly bonded with rubber vertical ribs, and the rubber vertical ribs are stuck between the damper and the inner wall of the straight-insertion tube;

[0008] By adopting the above technical solution, the damper is connected by being more tightly snapped into the straight-insert tube with the rubber vertical ribs.

[0009] Furthermore, the rubber ring gaskets are vertically arranged and bonded in three groups on the outer wall of the cannula;

[0010] By adopting the above technical solution, the three groups of rubber ring pads on the outer side of the insertion tube can be inserted into the straight insertion tube to perform friction buffering during vertical insertion.

[0011] Furthermore, the screw-on hole is centrally located on the telescopic rod head of the damper, and the depth of the screw-on hole is the same as the length of the screw rod.

[0012] By adopting the above technical solution, the screw rod can be screwed into the telescopic rod head of the damper better, and the screw rod can be completely accommodated by the screw-on hole.

[0013] Furthermore, the diameter of the connecting disk is larger than the diameter of the spring ring, and the connecting disk is pressed on the spring and the telescopic rod head of the damper;

[0014] By adopting the above technical solution, the connecting plate can be pressed on the telescopic rod head of the spring and the damper to perform linear downward pressure.

[0015] Furthermore, the diameter of the straight-insertion tube is the same as the diameter of the tube cavity of the seat tube, and the depth of the tube cavity of the straight-insertion tube is greater than the length of the damper;

[0016] By adopting the above technical solution, the barrel of the straight-insert barrel can be smoothly inserted into the seat tube, and then the damper and the inserting tube can be accommodated in the straight-insert barrel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model provides a straight-insertion tube at the seat tube of the electric bicycle body, and the straight-insertion tube is equipped with a shock-absorbing mechanism. When the electric bicycle body encounters bumpy road conditions, the insertion tube of the shock-absorbing mechanism below the seat is lowered in a linear friction-buffered manner at the straight-insertion tube with the help of a rubber ring pad. Then, the damper cooperates with the spring to form an elastic damping support in the straight-insertion tube, thereby reducing the vibration transmitted from the electric bicycle body to the seat, so that the rider sitting on the seat is less likely to feel discomfort when encountering bumpy road conditions.

[0019] And after there is a damping support under the seat, when the rider sits on the seat, the seat can provide damping support, so that the structure under the seat no longer contacts the seat tube of the electric bicycle, reducing the wear and tear of the seat tube.

A spring 7 is clamped on the outside of the telescopic rod of the damper 6, and a screw hole 8 for screwing a screw 9 is provided at the head of the telescopic rod of the damper 6. The screw 9 is welded to the outside of the bottom pipe mouth of the insert 11 through a connecting disk 10, and the upper end tube body of the insert 11 is fixed to the lower frame of the seat 13. A rubber ring pad 12 is bonded to the outer tube wall of the insert 11 with a clamp.

[0026] The outer shell of the damper 6 is annularly bonded with rubber vertical ribs 14, and the rubber vertical ribs 14 are stuck between the damper 6 and the inner wall of the straight-insertion tube 3;

[0027] By adopting the above technical solution, the damper 6 is more tightly inserted into the straight plug tube 3 by means of the rubber vertical ribs 14 for connection.

[0028] The rubber ring gaskets 12 are vertically arranged and bonded in three groups on the outer wall of the insert tube 11;

[0029] By adopting the above technical solution, the three groups of rubber ring pads 12 on the outside of the insertion tube 11 can be inserted into the straight insertion tube 3 to perform friction buffering during vertical insertion.

[0030] The screw hole 8 is centrally located at the telescopic rod head of the damper 6, and the depth of the screw hole 8 is the same as the length of the screw rod 9.

[0031] By adopting the above technical solution, the screw rod 9 can be screwed into the telescopic rod head of the damper 6 better, and the screw rod 9 can be completely accommodated by the screw-on hole 8.

[0032] The diameter of the connecting disk 10 is larger than the diameter of the ring of the spring 7, and the connecting disk 10 is pressed on the spring 7 and the telescopic rod head of the damper 6;

[0033] By adopting the above technical solution, the connecting plate 10 can be pressed on the spring 7 and the telescopic rod head of the damper 6 to perform linear downward pressure.

[0034] The diameter of the straight-insertion tube 3 is the same as the diameter of the tube cavity of the seat tube 2, and the depth of the tube cavity of the straight-insertion tube 3 is greater than the length of the damper 6;
