Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to a shock-absorbing structure of an electric bicycle which is easy to disassemble. Background Art

[0002] The front storage basket of an electric bicycle provides riders with convenient storage space for items needed for daily travel, such as shopping bags, backpacks, and water bottles, avoiding the fatigue of carrying heavy objects. The storage basket is usually located in the front of the bicycle, allowing riders to observe the status of the items in the basket at any time, reducing the risk of falling during driving, thereby improving safety. Structurally, the front storage basket usually consists of a frame, a basket body, fixings, and guardrails. The frame is mostly made of aluminum alloy or steel, providing good strength and durability; the basket body may be woven plastic or metal mesh to carry daily items. The design of the fixing device ensures that the storage basket can be firmly installed on the front of the bicycle to prevent it from loosening or falling off due to vibration or impact. The setting of guardrails or covers not only prevents items from falling, but also enhances the carrying capacity of the basket, allowing it to place higher items. At present, the front storage basket is generally installed on the electric bicycle frame through brackets and bolts. Therefore, when driving on bumpy roads, the items in the storage basket will be subject to frequent up and down vibrations. The continuous vibration will cause fatigue damage to the frame of the electric bicycle. Especially when driving on uneven roads, the connection part between the bracket and the frame will be subjected to repeated impacts, causing the screws to loosen, crack or even break, which not only affects the service life of the vehicle, but may also cause safety hazards during driving.

DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The utility model provides an embodiment of a shock-absorbing structure for an electric bicycle that is easy to disassemble, comprising a frame body 1 and a wide-mouth wheel cover 2 mounted on an outer wall of one side of the frame body 1. A U-shaped connector for mounting and fixing the wide-mouth wheel cover 2 is provided inside the wide-mouth wheel cover 2. Two parallel steel plates 5 extending obliquely upward are hinged to the top of the wide-mouth wheel cover 2. A notch 501 is provided on the surface of the steel plates 5. A basket 6 is fixed to one end of the two steel plates 5 away from the frame body 1. A hydraulic shock absorber 7 is hinged to the bottom end of the basket 6. The bottom end of the hydraulic shock absorber 7 is hinged to the top of the wide-mouth wheel cover 2.

[0019] An upper shaft bracket 3 is fixed to the top of the wide-mouth wheelhouse 2, and a rotating shaft 4 is rotatably mounted on the front and rear outer walls of the upper shaft bracket 3. Two steel plates 5 are fixedly connected to the rotating shaft 4 at one end away from the basket support 6. The two steel plates 5 are respectively fixed to the upper and lower surfaces of the rotating shaft 4. When the hydraulic shock absorber 7 is extended and retracted, the steel plates 5 and the basket support 6 can deflect around the rotating shaft 4 at a certain angle, allowing the hydraulic shock absorber 7 to function, thereby alleviating the vibration from the wide-mouth wheelhouse 2 and further dissipating the vibration energy.

[0020] An inner recess 201 is provided on the outer wall of the wide-mouth wheel housing 2 away from the vehicle frame body 1. The top end of the piston rod of the hydraulic shock absorber 7 is hingedly connected to the bottom end of the basket support 6. The bottom end of the cylinder of the hydraulic shock absorber 7 extends into the interior of the inner recess 201 and is hingedly connected to the wide-mouth wheel housing 2.

[0021] The U-mouth connector includes a U-mouth column sleeve 202 integrally formed on the top wall of the wide-mouth wheel housing 2, a curved wall 203 provided inside the U-mouth column sleeve 202, and a flat wall 204 provided on the outer wall of the U-mouth column sleeve 202. A plurality of positioning bolts 205 for bolting the U-mouth column sleeve 202 and the frame body 1 are mounted on the flat wall 204. An internal threaded cavity for screwing the positioning bolts 205 into is provided on one side of the outer wall of the frame body 1. The provision of the flat wall 204 facilitates screwing and tightening of the positioning bolts 205.

[0022] When the frame body 1 is connected to the wide-mouth wheel cover 2, the wide-mouth wheel cover 2 is docked with the frame body 1 through the U-mouth column sleeve 202. At this time, the U-mouth column sleeve 202 is fitted and fitted with the frame body 1 through the curved wall 203. Then the staff uses the positioning bolt 205 to fix the U-mouth column sleeve 202 and the frame body 1 together. By optimizing the connection method between the frame body 1 and the wide-mouth wheel cover 2 and using standardized positioning bolts 205, the staff can shorten the assembly time and reduce labor costs. During daily inspection and maintenance, damaged components can be quickly disassembled and replaced without tedious operations.

[0023] When the embodiment of the present application is in use, the staff first fixes the wide-mouth wheel cover 2 to the frame body 1 of the electric bicycle through the U-mouth connector and in the form of bolts. At this time, the rotation of the handlebars and front fork of the electric bicycle is not affected and can rotate normally. Then the staff fixes the storage basket on the top of the basket holder 6. During riding, the front wheel of the electric bicycle will encounter different road conditions. These uneven roads will produce vibrations and impacts. The front fork receives the vibrations transmitted by the road through the wheel. These vibrations will gradually be transmitted upward along the front fork to the frame body 1. Since the wide-mouth wheel cover 2 is fixed on the frame body 1, any vibration from the ground will affect the wide-mouth wheel cover 2. When the vibration When the force is transmitted to the wide-mouth wheel arch 2 through the frame body 1, the hydraulic shock absorber 7 begins to work, which uses the flow of hydraulic oil inside the shock absorber to absorb the impact force. The piston of the hydraulic shock absorber 7 will move in the internal hydraulic oil to form a damping effect. At this time, the flow of hydraulic oil will offset part of the vibration energy, thereby reducing the direct impact of the vibration on the steel plate 5, the basket support 6, and the storage basket. The steel plate 5, as a rigid structure, helps to transmit and disperse the impact force, alleviate the vibration from the wide-mouth wheel arch 2, and further disperse the vibration energy. Through the joint action of the hydraulic shock absorber 7 and the steel plate 5, the basket support can remain relatively stable, so that the vibration and impact force on the items in the storage basket are significantly reduced.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
