Description

Technical Field

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

[0002] Electric bicycles are vehicles that use batteries as auxiliary power sources and are based on ordinary bicycles, with the addition of motors, controllers, batteries, throttles, brake levers, and other control components and display systems. They have pedal-assist functionality, a certain range, and are convenient to ride, so they are widely used as short-distance commuting vehicles.

[0003] According to the announcement number CN217740673U, a battery with shock-absorbing plates for three-wheeled electric vehicles can reduce the vibration of the battery under the action of the shock-absorbing mechanism, which solves the problem that the battery of three-wheeled electric vehicles is easily damaged when subjected to vibration. It can better protect the battery from vibration and improve the service life of the battery.

[0004] The battery boxes used in existing electric vehicles are mostly simple open or semi-closed box structures without any special protective devices inside. However, during the operation of electric vehicles, the vibration and bumps caused by uneven road surfaces will cause the battery placed in the battery box to collide frequently with the inner wall of the box, which can easily cause wear and deformation of the battery shell. In severe cases, it may affect the stability of the electrical connection inside the battery and shorten the battery's service life.

[0005] Therefore, there is an urgent need to provide a frame for electric vehicles to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a frame for an electric vehicle.

[0007] To solve the above-mentioned technical problems, the present invention provides a vehicle frame, including a frame tube, with a front frame fixed to one end of the frame tube and a rear frame fixed to the other end of the frame tube.

[0008] A single support bracket is installed at the bottom end of the frame tube, a shock absorber is rotatably installed on one side of the frame tube, and a shock absorber is rotatably installed between the shock absorber and the rear frame.

[0009] The frame tubes and rear frame are equipped with a buffer mechanism inside that can effectively absorb and disperse bumps from the road surface. The buffer mechanism is equipped with a protective mechanism inside that can prevent the battery from colliding with the housing in all directions.

[0010] Through the above technical solution, the shock absorber frame uses shock absorbers to dampen the frame tubes, reducing the impact of road bumps on electric vehicles.

[0011] The present invention is further configured such that: the buffer mechanism includes a battery housing fixed inside the frame tube and the rear frame, the inner bottom wall of the battery housing is fitted with a first rubber cylinder shell, and the external thread of the first rubber cylinder shell is fitted with a first bolt that passes through and extends into the battery housing.

[0012] The above technical solution allows for the disassembly and assembly of the first rubber cylinder shell and the battery shell via the first bolt, thus facilitating the maintenance of the buffer mechanism.

[0013] The present invention is further configured such that: a first rubber seat rod is fitted inside the first rubber cylinder shell, a first spring is fixed at the bottom end of the first rubber seat rod, and a mounting plate is fixed at the top end of the first rubber seat rod.

[0014] Through the above technical solution, the first spring drives the first rubber seat rod to extend to the outside of the first rubber cylinder shell. When the first rubber seat rod retracts, the first rubber seat rod will rub against the first rubber cylinder shell for buffering.

[0015] The present invention is further configured such that: a mounting pressure plate is fitted on the outside of the mounting plate, a guide rail fixing plate is attached to the top of the mounting pressure plate, and a second bolt is installed on the internal thread of the guide rail fixing plate, one end of which passes through and extends to the outside of the mounting pressure plate.

[0016] The above technical solution allows for the disassembly and assembly of the guide rail fixing plate and the mounting pressure plate via the second bolt, thus facilitating the maintenance of the buffer mechanism.

[0017] The present invention is further configured such that: the protective mechanism includes a guide rail slide plate slidably mounted on the top of the guide rail fixing plate, a sliding box is slidably mounted on the top of the guide rail slide plate, a battery body is fitted inside the sliding box, and a lifting handle is rotatably mounted on the top of the battery body.

[0018] Through the above technical solution, the guide rail slide plate slides through the guide rail fixing plate, and the sliding box slides through the guide rail slide plate, allowing the sliding box to slide in all directions. The battery body can be picked up and put in by hand using the lifting handle. This utility model is further configured such that: a second rubber cylinder shell is attached to all four sides of the sliding box, and a third bolt with one end penetrating and extending into the interior of the sliding box is installed on the external thread of the second rubber cylinder shell.

[0019] Through the above technical solution, the second rubber cylinder shell and the sliding box can be disassembled and assembled using the third bolt, thereby facilitating the maintenance of the protective mechanism. This utility model is further configured such that: a second rubber seat rod is fitted inside the second rubber cylinder shell, a second spring is fixed to one end of the second rubber seat rod, and the other end of the second spring is fitted to one side of the sliding box.

[0020] Through the above technical solution, the second spring drives the second rubber seat rod to extend to the outside of the second rubber cylinder shell. When the second rubber seat rod retracts, the second rubber seat rod will rub against the second rubber cylinder shell for buffering.

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

[0022] 1. This utility model, by incorporating a buffer mechanism, can effectively absorb and disperse the energy from road bumps, significantly reducing the impact force on the battery. Compared with traditional battery boxes without a buffer structure, it has a better buffering effect, reduces damage to the battery caused by vibration and collision, extends the battery's service life, and reduces the user's replacement cost.

[0023] 2. By incorporating a protective mechanism, this utility model forms a complete protective system around the battery, preventing the battery from colliding with the housing in all directions, providing more comprehensive protection, reducing the number of repairs due to malfunctions, lowering safety hazards caused by battery damage, and improving the safety of electric vehicles.
