[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figures 1-9 , the present invention provides a battery energy supply device, which includes a battery pack 1 and a plurality of mounting plates 2 fixedly connected to the outside of the battery pack 1. Both sides of the battery pack 1 are fixedly connected with protection tubes 3. One end between the two protection tubes 3 is fixedly connected with a protection cross tube. The other end between the two protection tubes 3 is provided with a baffle assembly 6 for protecting the battery. A protection plate assembly is fixedly installed at the bottom of the battery pack 1. A heat dissipation mechanism is arranged between the protection plate assembly and the battery pack 1. A filtering and protection mechanism is arranged at one end of the protection plate assembly.

[0030] Refer to Figure 2 and Figure 3 , further, a plurality of connecting plates 7 are fixedly connected to the bottom of the protection tube 3. A sealing plate 4 is fixedly connected to the inside of the protection tube 3. A plurality of buffer air holes 5 are opened at one end of the inner wall of the protection tube 3. The baffle assembly 6 includes two support sliding rods 63, which are respectively slidably connected to the inner walls of the two protection tubes 3. A protection baffle 61 is fixedly connected between the two support sliding rods 63. A plurality of ventilation filter grooves 62 are opened on the surface of the protection baffle 61. Buffer pistons 65 are fixedly connected to one ends of the two support sliding rods 63. Plastic support plates 64 are fixedly connected to both sides of the connection between the two support sliding rods 63 and the protection baffle 61. The plurality of plastic support plates 64 are respectively arranged between the two protection tubes 3 and the protection baffle 61;

[0031] During use, the protective tubes 3 are installed on both sides of the battery pack 1, and a cross tube is fixedly connected to one end between the two protective tubes 3, which can enhance the support and protection effect. Sealing plates 4 are fixedly connected to the inside of the other ends of the two protective tubes 3. A number of buffer air holes 5 of appropriate sizes are opened in the section between the ends of the protective tubes 3 and the sealing plates 4. The baffle assembly 6 is installed inside the two protective tubes 3. Two support sliding rods 63 are fixedly connected to one side of the protective baffle 61. The two support sliding rods 63 are respectively installed inside the two protective tubes 3. A proper length of the support sliding rods 63 is inserted into the protective tubes 3. Plastic support plates 64 are arranged on both sides of the two support sliding rods 63. The plastic support plates 64 have a certain support strength and are fixedly connected to the protective baffle 61 and the ends of the protective tubes 3, so that the baffle assembly 6 and the protective tubes 3 are relatively fixed. If the protective baffle 61 collides slightly with gravel or other objects, the plastic support plates 64 can withstand the impact, and the relatively small impact force acts on the battery pack 1, and the force received is dispersed by other components, so that the battery pack 1 is basically not damaged. A number of ventilation filter grooves 62 are opened on the protective baffle 61, which can not only allow air to pass through for heat dissipation of the subsequent battery pack 1, but also block some larger stone particles, and can also provide protection for the battery pack 1. If a relatively large impact occurs, after the protective baffle 61 is subjected to a relatively large impact, the plastic support plates 64 break directly, and the support sliding rods 63 drive the buffer pistons 65 to move towards the sealing plates 4 inside the protective tubes 3. At this time, the support sliding rods 63 quickly drive the buffer pistons 65 to move, and the air in the section between the sealing plates 4 and the protective tubes 3 is quickly compressed. The compressed air is discharged through the buffer air holes 5 at an appropriate speed, which can achieve a relatively good buffering effect and reduce the impact force received by the battery pack 1.

[0032] Refer to Figures 4-9, Further, the guard plate assembly includes a protective bottom plate 8. Connecting pillars 10 are fixedly connected to the four corners at the top of the protective bottom plate 8. A plurality of weight reduction grooves 9 are formed in the middle of the protective bottom plate 8. An installation groove 11 is formed in the middle of the top of the protective bottom plate 8. A baffle chute 19 is formed on one side of the surface of the protective bottom plate 8. The heat dissipation mechanism includes a plurality of load-bearing support plates 12. Connecting bumps 13 and connecting grooves 14 are respectively arranged on both sides of the plurality of load-bearing support plates 12. Screw hole plates are fixedly connected to both ends of the plurality of load-bearing support plates 12. Heat dissipation elements are arranged on the surfaces of the plurality of load-bearing support plates 12. The plurality of load-bearing support plates 12 are fixedly installed inside the installation groove 11. The heat dissipation element includes a glass inclined tube 15. The glass inclined tube 15 is fixedly connected to the load-bearing support plate 12. A soft connection sleeve 16 is arranged at one end of the glass inclined tube 15. Heat-conducting silica gel 17 is filled inside both the glass inclined tube 15 and the soft connection sleeve 16. The material of the soft connection sleeve 16 is silica gel material. The property of the heat-conducting silica gel 17 is soft. The filtering and protection mechanism includes a thin baffle 18. The thin baffle 18 is slidably connected inside the baffle chute 19. Support sliders are fixedly connected to both ends of the thin baffle 18. Support chutes are formed at both ends of the baffle chute 19. The surface of the support slider is slidably connected to the inside of the support chute. A limit hole 23 is formed at the bottom of one side of the thin baffle 18. A plurality of cleaning rods 20 are fixedly connected inside the baffle chute 19. The surface of the cleaning rod 20 is slidably connected to the inside of the thin baffle 18. A limit groove 21 is formed at the connection between the baffle chute 19 and the protective bottom plate 8. A spring groove 22 is formed inside the limit groove 21. A clamping component is slidably connected inside the spring groove 22. The clamping component includes a limit clamping plate 24. The surface of the limit clamping plate 24 is slidably connected to the inner wall of the spring groove 22. A reset spring 25 is fixedly connected to one side of the limit clamping plate 24. One end of the reset spring 25 is fixedly connected to one end of the inner wall of the spring groove 22. Operating rods 26 are fixedly connected to both sides of the connection between the limit clamping plate 24 and the reset spring 25. One end of the limit clamping plate 24 is clamped inside the limit hole 23;

[0033] When in use, a mounting groove 11 is opened on the surface of one side of the protective bottom plate 8, and a plurality of weight-reducing grooves 9 are opened in the middle of one side of the protective bottom plate 8. The shape of the weight-reducing groove 9 is triangular, and the triangle has stability, so that a part of the weight of the protective bottom plate 8 can be reduced, and the strength of the protective bottom plate 8 will not be greatly affected. The protective bottom plate 8 of the battery pack 1 will have a greater impact on the heat dissipation of the battery pack 1, and may cause the temperature inside the battery pack 1 to be too high. Therefore, a heat dissipation mechanism is added between the protective bottom plate 8 and the battery pack 1. The heat dissipation mechanism is divided into a plurality of small heat dissipation components. The top of the load-bearing support plate 12 is fixedly connected to the glass inclined tube 15, and a soft connecting sleeve 16 is provided at one end of the glass inclined tube 15. The inside of the glass inclined tube 15 and the soft connecting sleeve 16 are filled There is thermal conductive silicone 17, and the glass inclined tube 15 has a certain thickness. Connecting protrusions 13 and connecting grooves 14 are respectively provided on both sides of the load-bearing support plate 12. Multiple load-bearing support plates 12 can be spliced together. Grooves and protrusions are respectively provided on both sides of the mounting groove 11, which can cooperate with the connecting protrusions 13 and connecting grooves 14 of the side load-bearing support plate 12. Threaded holes are provided at both ends of the load-bearing support plate 12. The small heat dissipation component is fixedly installed inside the mounting groove 11 by bolts. The protective bottom plate 8 is installed to the bottom of the battery pack 1 through four connecting pillars 10 arranged on the protective bottom plate 8. The soft connection sleeve 16 has a certain support. After the protective bottom plate 8 is installed, the soft connection sleeve 16 is tightly against the bottom of the battery pack 1. The thermal conductive silicone inside the soft connection sleeve 16 17 can be in good contact with the battery pack 1, can well lead out the temperature of the battery pack 1, and can take away the drawn-out heat by the wind passing through the battery pack 1 and the protective bottom plate 8, which can well solve the problem of the protective bottom plate 8 blocking the heat dissipation. The use of the soft connection sleeve 16 to connect the battery pack 1 is to prevent the glass inclined tube 15 from breaking without collision. Because this battery pack 1 is used to be installed on the vehicle, it is inevitable that it will be deformed due to bumps. If the glass inclined tube 15 is used for connection throughout, it is easy to cause the glass inclined tube 15 to break due to deformation. The use of the soft connection sleeve 16 can effectively reduce the occurrence of this situation. The glass inclined tube is used because, if a collision occurs, the glass inclined tube 15 will break at the first time, reducing the damage to the battery pack 1. If a metal heat sink is used It is very likely to puncture the battery pack 1, and multiple small heat dissipation components are used in order to be able to replace broken heat dissipation components separately, which is beneficial to reduce the cost of use and is more convenient and quick to maintain. Because the heat pipe is made of glass material, and the heat pipe needs to reduce the adhesion of dust as much as possible, a fine baffle 18 is provided inside the baffle slide groove 19 opened on the protective bottom plate 8, and the fine baffle 18 has a fine groove. A cleaning rod 20 corresponding to the fine groove is fixedly connected to the inside of the baffle slide groove 19, and the surface of the cleaning rod 20 is slidably connected to the fine groove. A limiting groove 21 is opened at the bottom of the protective bottom plate 8, and a limiting card plate 24 is provided inside the limiting groove 21, which can be stuck in the limiting hole 23 opened on one side of the fine baffle 18, so as to limit the fine baffle 18.The fine baffle 18 can intercept particles that may break the glass inclined tube 15, and can intercept some dust to reduce the adhesion of dust on the glass inclined tube 15. During regular maintenance, we can pinch the operating rod 26 and pull it to one side. At this time, the reset spring 25 shrinks, and the limit card plate 24 leaves the inside of the limit hole 23. At this time, we can pinch the part of the fine baffle 18 inside the limit groove 21 and pull it up and down so that the dust inside the fine groove is cleaned by the cleaning rod 20. At this time, release the operating rod 26, and the reset spring 25 resets the limit card plate 24 to push the limit card plate 24 into the inside of the limit hole 23 to complete the limit.

[0034] When the embodiment of the present application is in use: a protective tube 3 is provided on the outside of the battery pack 1, and a baffle assembly 6 is provided at one end of the two protective tubes 3, which has a good buffer protection mechanism and can protect the connector circuit and other components provided at the end of the battery energy supply device. If it is subjected to a large impact, the protective baffle 61 is subjected to a large impact, and the plastic support plate 64 is directly broken, and the support slide bar 63 moves with the buffer piston 65 to the sealing plate 4 inside the protective tube 3. At this time, the support slide bar 63 quickly moves with the buffer piston 65, and the air in the section between the sealing plate 4 and the protective tube 3 is quickly squeezed, and the squeezed air is discharged at an appropriate speed through the buffer pores 5, which can play a relatively good buffering effect, reduce the impact force on the battery pack 1, have a certain buffering effect, can reduce the impact force on the battery, and more effectively protect the battery. The bottom of the battery pack 1 is provided with a protective bottom plate 8 with a heat dissipation mechanism. This heat dissipation mechanism is composed of multiple small heat dissipation mechanisms. If some of the small heat dissipation mechanisms are damaged due to bumps in the later stage, the guard plate can be removed for single The heat dissipation device can solve the problem of the protective plate affecting the heat dissipation, and the heat of the battery is drawn out through the heat-conducting material, and the heat is taken away by the wind during driving, which is beneficial to prevent the battery from overheating.
