Description

Technical Field

[0001] The utility model relates to an electric bicycle lithium battery with a long service life, belonging to the technical field of electric bicycle lithium batteries. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and a non-aqueous electrolyte solution; lithium ion batteries generally use lithium alloy metal oxides as the positive electrode material, graphite as the negative electrode material, and a non-aqueous electrolyte battery. Lithium ion batteries do not contain metallic lithium and are rechargeable.

[0003] The existing lithium batteries of electric bicycles still have some problems during use. The lithium batteries cannot be cooled and dissipated during use. The temperature will have a great impact on the working state of the lithium batteries. When the temperature is high, the service life of the lithium batteries will be shortened. In severe cases, the lithium batteries may explode, which increases the safety hazards during the use of lithium batteries. At the same time, the lithium battery box is installed inside the frame of the electric bicycle, and it will shake during driving, which will cause impact on the top of the lithium battery box, affecting the normal use of the lithium battery box. Utility Model Content

[0004] The purpose of the utility model is to provide an electric bicycle lithium battery with a long service life. The utility model has a simple structure and is easy to use. It can automatically dissipate heat inside the lithium battery box and has a buffering effect on the lithium battery box to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An electric bicycle lithium battery with a long service life comprises a lithium battery box, a cover plate is installed on the top of the lithium battery box, a heat dissipation hole is opened in the inner wall of the lithium battery box, an air pressure box is fixedly connected to the outer side of the lithium battery box, an air intake pipe is fixedly connected to the outer side of the air pressure box, a return spring is fixedly connected to the inner wall of the air pressure box, an air pressure plate is fixedly connected to the outer side of the return spring, a moving rod is fixedly connected to the outer side of the air pressure plate, a connecting block is fixedly connected to the outer side of the moving rod, a sealing plate is fixedly connected to the outer side of the connecting block, a sliding rod is fixedly connected to the outer side of the sealing plate, and a sliding groove is opened in the inner wall of the lithium battery box.

[0007] Furthermore, a nylon rod is fixedly connected to the bottom of the lithium battery box, a base is movably connected to the bottom of the nylon rod, a shock-absorbing spring is fixedly connected to the top of the base, a stabilizing plate is fixedly connected to the outside of the base, a lifting groove is provided inside the stabilizing plate, and a connecting rod is slidably connected to the inside of the lifting groove.

[0008] Furthermore, the heat dissipation holes are evenly distributed in the inner wall of the lithium battery box, and one end of the air intake pipe is located inside the lithium battery box.

[0009] Furthermore, the return spring is symmetrically distributed between the air pressure plate and the inner wall of the air pressure box, and the air pressure plate is slidably connected to the inside of the air pressure box.

[0010] Furthermore, the sealing plate is slidably connected to the outside of the heat dissipation hole, and the sliding rod is slidably connected to the inside of the sliding groove.

[0011] Furthermore, the top of the shock absorbing spring is fixedly connected to the bottom of the lithium battery box, and the shock absorbing spring is located on the outside of the nylon rod.

[0012] Furthermore, the stabilizing plates are symmetrically distributed on the outside of the base, and one end of the connecting rod away from the lifting slot is fixedly connected to the outside of the lithium battery box.

[0013] The beneficial effects of the utility model are:

[0014] (i) The utility model sets a lithium battery box, and the initial position of the sealing plate is on the outside of the heat dissipation hole, thereby blocking the heat dissipation hole and ensuring the sealing of the lithium battery box. When the temperature inside the lithium battery box rises, the hot air will enter the inside of the air pressure box through the air intake pipe, increasing the air pressure inside the air pressure box. At this time, the air pressure plate will move inside the air pressure box, thereby causing the air pressure plate to drive the moving rod to move. Since the sealing plate is slidably connected to the outside of the lithium battery box through the moving rod and the connecting block, the moving rod will stably slide on the outside of the lithium battery box under the action of the sliding rod, so that the heat dissipation holes in the inner wall of the lithium battery box leak out, and the high temperature inside the lithium battery box is dissipated. When the temperature returns to normal, the air pressure plate returns to its original position under the action of the reset spring, so that the sealing plate blocks the heat dissipation holes again, achieving the effect of automatic heat dissipation.

[0015] (ii) The utility model provides a lithium battery box and a base. When the top of the lithium battery box is hit, the shock-absorbing spring can buffer the lithium battery box. The base and the lithium battery box are movably connected to a nylon rod, so the nylon rod moves inside the base to eliminate the generated potential energy. A stabilizing plate is fixedly connected to the outside of the base, and one end of the connecting rod away from the lifting groove inside the stabilizing plate is fixedly connected to the outside of the lithium battery box. Therefore, the lithium battery box can maintain stability when it is hit and moved, thereby achieving the effect of extending its life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0024] An electric bicycle lithium battery with a long service life comprises a lithium battery box 1, a cover plate 2 is installed on the top of the lithium battery box 1, a heat dissipation hole 3 is opened in the inner wall of the lithium battery box 1, an air pressure box 4 is fixedly connected to the outer side of the lithium battery box 1, an air intake pipe 5 is fixedly connected to the outer side of the air pressure box 4, a return spring 6 is fixedly connected to the inner wall of the air pressure box 4, an air pressure plate 7 is fixedly connected to the outer side of the return spring 6, a moving rod 8 is fixedly connected to the outer side of the air pressure plate 7, a connecting block 9 is fixedly connected to the outer side of the moving rod 8, a sealing plate 10 is fixedly connected to the outer side of the connecting block 9, a sliding rod 11 is fixedly connected to the outer side of the sealing plate 10, and a sliding groove 12 is opened in the inner wall of the lithium battery box 1.

[0025] Specifically, Figure 1 As shown, the heat dissipation holes 3 are evenly distributed in the inner wall of the lithium battery box 1, one end of the air intake pipe 5 is located inside the lithium battery box 1, the return spring 6 is symmetrically distributed between the air pressure plate 7 and the inner wall of the air pressure box 4, and the air pressure plate 7 is slidably connected to the inside of the air pressure box 4, the sealing plate 10 is slidably connected to the outside of the heat dissipation holes 3, and the sliding rod 11 is slidably connected to the inside of the slide groove 12.

[0026] When the temperature inside the lithium battery box 1 increases, the hot air will enter the inside of the air pressure box 4 through the air inlet pipe 5, thereby increasing the air pressure inside the air pressure box 4. At this time, the air pressure plate 7 will move inside the air pressure box 4, thereby causing the air pressure plate 7 to drive the moving rod 8 to move. Since the sealing plate 10 is slidably connected to the outside of the lithium battery box 1 through the moving rod 8 and the connecting block 9, the moving rod 8 will slide stably on the outside of the lithium battery box 1 under the action of the sliding rod 11, so that the heat dissipation holes 3 in the inner wall of the lithium battery box 1 leak out, and the high temperature inside the lithium battery box 1 is dissipated. When the temperature returns to normal, the air pressure plate 7 returns to its original position under the action of the reset spring 6, thereby causing the sealing plate 10 to block the heat dissipation holes 3 again, thereby achieving the effect of automatic heat dissipation.

[0029] In this embodiment: by setting up a lithium battery box 1 and a base 14, when the top of the lithium battery box 1 is hit, the shock-absorbing spring 15 can buffer the lithium battery box 1, and the base 14 and the lithium battery box 1 are movably connected to the nylon rod 13, so the nylon rod 13 will move inside the base 14, thereby eliminating the generated potential energy, and a stabilizing plate 16 is fixedly connected to the outside of the base 14, and the end of the connecting rod 18 away from the lifting groove 17 inside the stabilizing plate 16 is fixedly connected to the outside of the lithium battery box 1, so that the lithium battery box 1 can maintain stability when it is hit and moved, thereby achieving the effect of extending the life.
