[0001] The utility model relates to the technical field of electric bicycles, in particular to an electric bicycle with a battery protection structure. Background Art

[0002] An electric bicycle is a vehicle that uses a battery as an auxiliary energy source and is based on an ordinary bicycle and is equipped with a motor, controller, battery, handlebar, brake handle and other operating components and a display instrument system.

[0003] When riding an electric bicycle, it is inevitable to encounter uneven roads and potholes, which causes the electric bicycle to vibrate during driving. This vibration will be transmitted along the frame of the electric bicycle to the battery, causing the battery to resonate, making the battery placed in the battery compartment easy to loosen under vibration, resulting in poor contact of the battery's electrical connection, affecting the power supply to the hub motor, and thus affecting the normal movement of the electric bicycle. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose an electric bicycle with a battery protection structure.

[0005] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: an electric bicycle with a battery protection structure is designed, comprising a body, a battery compartment is provided on the body, the battery compartment is fixed on a mounting frame, and the mounting frame is fixed on the body;

[0006] There are clamping plates on both sides of the battery compartment. Spline sleeves are rotatably installed on the sides of the two clamping plates that are relatively far away from each other. Threads are opened on the surface of the spline sleeves, and the spline sleeves are threaded with nuts. The nuts are fixed to the inner wall of the battery compartment through a fixing frame.

[0007] A spline shaft is built into the end of the spline sleeve away from the spline plate, and a rotating shaft is installed at the other end of the spline shaft. The other end of the rotating shaft passes through the battery compartment and is connected to a handle, and the rotating shaft is rotatably connected to the side wall of the battery compartment.

[0008] Preferably, each splint is connected to both sides with a strip-shaped connecting plate, and a strip-shaped support plate is vertically installed at the other end of the connecting plate. An inclined pressure plate is provided on the side of the support plate close to the connecting plate, and the pressure plate is connected to the end of the support plate through an arc plate, and the pressure plate and the arc plate are both elastic metal sheets.

[0009] Preferably, a rubber sleeve with a rough surface is sleeved on the pressing plate.

[0010] Preferably, the battery compartment is a box body with an opening at the top, and a sealing cover is hinged on one side of the top of the battery compartment, and the other side of the sealing cover is connected to the battery compartment through a lock.

[0011] Preferably, a pressing block is installed on a side of the sealing cover close to the battery compartment, and the pressing block is an elastic rubber block.

[0012] Preferably, a controller is provided at the bottom of the battery compartment, and an electrical socket is also provided in the battery compartment. The electrical socket is mounted on a fixing plate, and the end of the fixing plate is fixed to the inner wall of the battery compartment.

[0013] Preferably, the vehicle body includes a frame, a drive wheel is rotatably mounted on the bottom of one end of the frame, the drive wheel includes a hub motor and a tire arranged on the hub motor, wherein the hub motor is connected to the controller via a wire, and the mounting frame is fixed to one end of the frame near the drive wheel;

[0014] A driven wheel is provided below the other end of the frame. The driven wheel is rotatably mounted on a connecting frame. The connecting frame is rotatably connected to the frame, and a handlebar is mounted on the top of the connecting frame.

[0015] The design scheme proposed by the utility model has the following beneficial effects during application:

[0016] 1. The electric bicycle with a battery protection structure rotates the spline sleeve on the nut, so that the clamping plate can move linearly in the battery compartment. When the two clamping plates are against the outer wall of the battery, the battery in the battery compartment is clamped and tightened, ensuring the stability of the battery when the electric bicycle is moving.

[0017] 2. When the electric bicycle with a battery protection structure approaches the battery, the pressure plate is in close contact with the side of the battery, and the elastic deformation of the curved plate allows the pressure plate to have a force acting in the direction of the battery. This can cooperate with the splint to wrap and fix the four sides of the battery, so as to further improve the stability of the battery in the battery compartment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figures 1-4 , an electric bicycle with a battery protection structure, comprising a vehicle body, wherein, as Figure 1 As shown, the vehicle body includes a frame 1, a driving wheel 4 is rotatably mounted at the bottom of one end of the frame 1, and the driving wheel 4 includes a hub motor and a tire arranged on the hub motor. A driven wheel 3 is provided below the other end of the frame 1, and the driven wheel 3 is rotatably mounted on a connecting frame. The connecting frame is rotatably connected to the frame 1, and a handlebar 2 is installed on the top of the connecting frame.

[0025] like Figure 1 As shown, a battery compartment 6 is provided on the vehicle body, and the battery compartment 6 is fixed on the mounting frame 5. In actual use, the battery compartment 6 is fixed to the mounting frame 5 by bolts, and the mounting frame 5 is fixed to the vehicle body, that is, the mounting frame 5 is fixed to one end of the frame 1 close to the driving wheel 4;

[0026] like Figure 3 and Figure 4 As shown, both sides of the interior of the battery compartment 6 are provided with clamping plates 15, and a spline sleeve 12 is rotatably installed on the side of the two clamping plates 15 that is relatively far away. A thread is provided on the surface of the spline sleeve 12, and a nut 13 is threadedly connected to the spline sleeve 12. The nut 13 is fixed to the inner wall of the battery compartment 6 through a fixing frame 14, so that when the spline sleeve 12 rotates, it can push the clamping plates 15 to make a linear motion in the battery compartment 6. In this way, after the battery is placed in the battery compartment 6, the clamping plates 15 can be placed against the side of the battery, so that the battery is tightened under the relative action of the two clamping plates 15;

[0027] During actual use, a spline shaft 11 is built into the end of the spline sleeve 12 away from the spline plate 15, and a rotating shaft 9 is installed at the other end of the spline shaft 11. The other end of the rotating shaft 9 passes through the battery compartment 6 and is connected to the handle 10, and the rotating shaft 9 is rotatably connected to the side wall of the battery compartment 6. Under the mutual limitation of the spline shaft 11 and the spline sleeve 12, the rotation of the rotating shaft 9 can drive the spline sleeve 12 to rotate synchronously, and the rotation of the spline sleeve 12 can enable it to slide on the spline shaft 11 along the axial direction of the spline shaft 11, so that the movement of the spline plate 15 will not drive the synchronous movement of the handle 10, ensuring that the spatial position of the handle 10 will not be too large to affect the surrounding environment, that is, when a person passes by the side of the battery compartment 6, he will not be scratched by the handle 10.

[0028] The two ends of the battery pack 11 are fixedly secured to the battery compartment 6 by means of a strip-shaped connecting plate 16, which is fixed to the battery compartment 6 at the other end.

[0029] In order to further improve the contact effect between the pressing plate 18 and the battery, a rubber sleeve with a rough surface is provided on the pressing plate 18 .

[0030] Specifically, the battery compartment 6 is a box with an opening at the top, and a sealing cover 7 is hinged on one side of the top of the battery compartment 6. The other side of the sealing cover 7 is connected to the battery compartment 6 by a lock, which facilitates the opening and closing of the battery compartment 6 and facilitates the removal, placement and replacement of the battery; a pressure block 8 is installed on the side of the sealing cover 7 close to the battery compartment 6. The pressure block 8 is an elastic rubber block. When the sealing cover 7 is closed on the battery compartment 6, the pressure block 8 will press on the top of the battery, thereby providing the battery compartment 6 with a fastening effect in the vertical direction.

[0031] It should be noted that a controller 22 is provided at the bottom of the battery compartment 6, and a power socket 20 is also provided in the battery compartment 6. The power socket 20 is mounted on a fixing plate 21, and the end of the fixing plate 21 is fixed to the inner wall of the battery compartment 6. The power socket 20 and the hub motor are connected to the controller 22 through wires to provide power for the electric bicycle to move.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
