Description

Technical Field

[0001] This utility model relates to the technical field of battery box fixing devices for electric motorcycles, and in particular to a battery box clamping device for quick loading and unloading. Background Technology

[0002] The battery box of most electric motorcycles is placed in the middle of the frame under the seat. The frame includes a left frame and a right frame, with a cavity for installing the battery box in the middle of the left and right frames. The battery box includes a box body and a box cover. The box body is set in the cavity, and the battery is tightly fitted in the box body. A locking hook is set on the rear of the box body, and a locking clip is set on the rear of the box body, which is hinged to the front of the box body. The locking hook is rotated open and locked onto the locking clip by external force. Although the locking cover of this type of battery box can fix the box cover on the box body, thereby pressing the battery inside tightly from the top of the box body, its mechanism is complex. The positions of the padlock and locking clip need to be accurately defined, otherwise there is a defect that it cannot be pressed tightly. At the same time, it is not possible to quickly open the battery box cover and quickly load and unload the battery inside the battery box. Utility Model Content

[0003] To address the shortcomings of existing battery box clamping devices, which are complex and cannot be quickly installed and removed, the purpose of this invention is to provide a battery box clamping device that can be quickly installed and removed. This device has a simple structure and can quickly clamp and release the battery box.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A quick-release battery box clamping device is disclosed. The battery box includes a box body and a box cover, and mounting seats are provided at both the front and rear ends of the box body. The clamping device includes a screw, a lower shaft pin, an upper shaft pin, and a cam handle. The upper end of the screw is fixedly and laterally connected to the upper shaft pin. The mounting seat is laterally provided with a lateral mounting hole that matches the diameter of the lower shaft pin. The lower end of the screw is provided with an external thread. The middle of the lower shaft pin is provided with an internal thread that matches the external thread in a vertical direction. The cam handle has a lateral mounting hole at the cam shaft that matches the diameter of the upper shaft pin.

[0006] Using the above technical solution, the battery box is fixed to the frame of the electric vehicle. In electric motorcycles, the battery box is mostly placed in the middle of the frame under the seat. The frame includes a left side frame and a right side frame, with a cavity for installing the battery box between them. The battery box includes a body and a cover. The front and rear ends of the body are equipped with mounting seats. First, the cover is pre-placed on the body. Then, the lower axle pin is laterally matched and placed in the lateral mounting hole of the mounting seat. This lower axle pin can also be directly and integrally set in the mounting seat. Then, the lower section of the screw is threaded onto the lower axle pin. The degree of screwing ensures that the cam part of the cam handle is pre-pressed in the small-diameter state (when the handle part of the cam handle is vertical). On the lid, a transverse mounting hole matching the diameter of the upper shaft pin is provided at the cam shaft of the cam handle. The upper shaft pin is hinged at the cam shaft of the cam handle. The cam part has enough space to allow the screw to pass through vertically. Alternatively, the upper shaft pin can be used as the transverse cam shaft of the cam part of the cam handle. The upper shaft pin has an internal thread matching the external thread of the upper section of the screw in the vertical direction. Finally, by rotating the cam handle, the lid is quickly pressed onto the box body. At this time, the cam part of the cam handle is in the large diameter state (the handle of the cam handle is horizontal in this state); conversely, to loosen, simply rotate the cam handle in the opposite direction.

[0007] By adopting the above technical solution, the cam can be rotated by rotating the handle, which can quickly press and release the battery box, making it convenient for battery repair or replacement.

[0008] Further, it also includes a pad, the pad having a vertical mounting hole in the middle that matches the diameter of the screw, the pad being movably fitted onto the upper section of the screw, located below the upper shaft pin.

[0009] The purpose of adding the pad is to better ensure the contact area with the lid and to better transmit the pressure of the cam handle to the box body. When using it, ensure that the pad is in contact with the box body during pre-pressing.

[0010] Furthermore, the upper surface of the pad is provided with a downwardly recessed arc-shaped groove that matches the engagement point of the cam part handle. This structure can better ensure the pressing effect.

[0011] In addition, considering the directional stability of the screw, the front and rear ends of the housing are provided with positioning vertical grooves corresponding to the screw. The positioning vertical grooves extend from the upper edge of the housing to the mounting base. In use, after the lower section of the screw is threaded into the lower shaft pin, the rod is pushed and locked into the positioning vertical groove. In this way, the positioning vertical groove can better ensure the verticality of the screw in the vertical direction and ensure the clamping effect of the cam handle.

[0012] The shape of the cam handle is further defined, specifying that the cam handle includes a handle portion at the left end and a cam portion at the right end, wherein the handle portion is elongated and flat.

[0013] By adopting the above technical solution, the long and flat shape is convenient for hand operation, increases the contact area, and the rounded and smooth tail avoids hand injury.

[0014] The present invention is further provided that a protective sleeve is installed at the bottom of the screw.

[0015] By adopting the above technical solution, the screw can be prevented from retracting and the impact damage caused by the bottom of the screw can be protected when it is placed in the mounting bracket of the battery box.

[0016] The present invention is further configured such that the protective sleeve is made of rubber.

[0017] By adopting the above technical solution, the rubber material has good cushioning ability and can effectively protect the bottom of the screw.

[0018] The battery box clamping device using the above technical solution has a simple structure and can quickly clamp and release the battery box. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-3As shown, a quick-release battery box clamping device is disclosed. The battery box includes a box body 10 and a box cover 20. The box body 10 is provided with mounting seats 30 at both the front and rear ends. The clamping device includes a screw 11, a lower shaft pin 12, an upper shaft pin 13, and a cam handle 14. The upper end of the screw 11 is fixedly and laterally connected to the upper shaft pin 13. The mounting seat 30 is laterally provided with a lateral mounting hole that matches the diameter of the lower shaft pin 12. The lower end of the screw 11 is provided with an external thread. The middle of the lower shaft pin 12 is provided with an internal thread that matches the external thread in the vertical direction. The cam handle 14 is laterally provided with a lateral mounting hole that matches the diameter of the upper shaft pin 13 at the cam shaft.

[0024] Using the above technical solution, the battery box is fixed to the frame of the electric vehicle. In electric motorcycles, the battery box is mostly placed in the middle of the frame under the seat. The frame includes a left side frame and a right side frame, with a cavity for installing the battery box between them. The battery box includes a body and a cover. The front and rear ends of the body 10 are each provided with a mounting seat 30. First, the cover 20 is pre-placed on the body. Then, the lower axle pin is laterally matched and placed in the lateral mounting hole of the mounting seat. This lower axle pin 12 can also be directly and integrally set in the mounting seat 30. Then, the lower section of the screw 11 is threaded onto the lower axle pin 12. The degree of screwing ensures that the cam portion 142 of the cam handle 14 is pre-pressed onto the cover 10 in the small-diameter state (when the handle portion 141 of the cam handle is vertical). Then, since the cam shaft of the cam handle 14 is provided with a transverse mounting hole that matches the diameter of the upper shaft pin 13, the upper shaft pin 13 is hinged to the cam shaft of the cam handle 14. The cam part is provided to ensure that the screw can pass through vertically. Of course, the upper shaft pin can also be used as the transverse cam shaft of the cam part of the cam handle. The upper section of the screw is provided with an external thread, and the middle of the upper shaft pin is provided with an internal thread that matches the external thread of the upper section of the screw in a vertical direction. Finally, by rotating the cam handle 14, the box cover 10 is quickly pressed onto the box body 30. At this time, the cam part of the cam handle 14 is in a large diameter state (in this state, the handle of the cam handle 14 is in a horizontal state); conversely, when unloading, simply rotate the cam handle 14 in the opposite direction.

[0025] By adopting the above technical solution, the cam can be rotated by rotating the handle, which can achieve the effect of tightening and loosening, making it convenient for battery repair or replacement.

[0026] Further, it also includes a pad 15, which has a vertical mounting hole in the middle that matches the diameter of the screw 11. The pad 15 is movably sleeved on the upper section of the screw 11 and is located below the upper shaft pin 13.

[0027] The purpose of adding pad 15 is to better ensure the contact area with the lid and to better transmit the pressure of the cam handle to the box body. When using, when the pre-pressure starts, ensure that pad 15 is in pre-pressure contact with the box body.

[0028] Furthermore, the upper surface of the pad 15 is provided with a downwardly recessed arc-shaped groove 151 that matches the engagement point of the cam portion 142 of the cam portion handle. This structure can better ensure the pressing effect.

[0029] In addition, considering the orientation and stability of the screw, the front and rear ends of the housing 20 are provided with positioning vertical grooves 17 corresponding to the screw 11. The positioning vertical grooves 17 extend from the upper edge of the housing to the mounting base. In use, after the lower section of the screw 11 is threaded into the lower shaft pin, the rod is pushed and locked into the positioning vertical groove 17. In this way, the positioning vertical groove 17 can better ensure the verticality of the screw 11 in the vertical direction and ensure the tightening effect of the cam handle 14.

[0030] The shape of the cam handle 14 is further defined, and the cam handle includes a handle portion 141 at the left end and a cam portion 142 at the right end. The handle portion 141 is long and flat. By adopting the above technical solution, the long and flat handle portion 141 is convenient for hand operation and increases the contact area. The arc-shaped tail is smooth and flat, avoiding injury to the hand.

[0031] The present invention is further provided that a protective sleeve 16 is installed at the bottom of the screw 11.

[0032] By adopting the above technical solution, the screw can be prevented from retracting and the impact damage caused by the bottom of the screw can be protected when it is placed in the mounting bracket of the battery box.

[0033] The present invention is further configured such that the protective sleeve 16 is made of rubber.

[0034] By adopting the above technical solution, the rubber material has good cushioning ability and can effectively protect the bottom of the screw.

[0035] The battery box clamping device using the above technical solution has a simple structure and can quickly clamp and release the battery box.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
