Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a combined housing for power batteries. Background Technology

[0002] "Power batteries" refer to rechargeable batteries specifically designed to provide driving energy for electric and hybrid vehicles. They are the "heart" of electric vehicles, directly determining the vehicle's range, performance, cost, and safety.

[0003] As a key load-bearing component of power battery packs, existing modular housings mostly adopt an integrated frame or a fixed-interval partition structure. The distance between the mounting positions for accommodating power batteries is predetermined and cannot be flexibly adjusted according to actual usage needs. This fixed-distance design results in extremely poor adaptability of the housing. When faced with power batteries of different specifications and sizes, it is necessary to specially customize corresponding modular housings, which greatly increases the production and manufacturing costs and design cycle. Therefore, a modular housing for power batteries is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problem that the distance between the mounting positions for accommodating power batteries inside existing modular housings is fixed in advance, making it impossible to flexibly adjust according to actual usage needs. This fixed distance design results in extremely poor adaptability of the housing. When faced with power batteries of different specifications and sizes, it is necessary to specially customize corresponding modular housings, which greatly increases the production and manufacturing costs and design cycle. Therefore, this invention proposes a modular housing for power batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined housing for a power battery includes a housing with rectangular grooves on both inner walls. A rectangular plate is fixedly connected to each rectangular groove. Fixing frames are fixedly connected to the rectangular grooves on both sides. A first mounting plate is provided between the fixing frames. A first movable frame and a second movable frame are respectively provided above and below the fixing frames. A second mounting plate is provided between the first movable frame and the second movable frame. A first bevel gear and a second bevel gear are provided in one of the rectangular grooves. An adjustment mechanism is provided inside the housing to raise and lower the first movable frame and the second movable frame through the first bevel gear and the second bevel gear.

[0007] Preferably, the adjustment mechanism includes a rotating rod rotatably connected to the housing and symmetrically arranged, one end of the rotating rod being fixedly connected to a knob, and the other end of the rotating rod being fixedly connected to a first bevel gear. Symmetrically arranged threaded rods are rotatably connected above and below the rectangular plate, one end of the threaded rod being fixedly connected to a second bevel gear, the second bevel gear meshing with the first bevel gear. A lifting block is threadedly connected to the threaded rod, and the lifting block is fixedly connected to one side of the first moving frame and the second moving frame, respectively.

[0008] Preferably, a sliding rod is fixedly connected to one side of the rectangular groove, and a moving block is fixedly connected to one side of the first moving frame and the second moving frame, and the moving block is slidably connected to the sliding rod.

[0009] Preferably, the fixed frame, the first movable frame, and the second movable block are all provided with limit grooves, and limit rods are fixedly connected in the limit grooves. Movable plates are fixedly connected to both sides of the first mounting plate and the second mounting plate, and the movable plates are slidably connected to the limit rods. A handle is fixedly connected to one side of the first mounting plate and the second mounting plate.

[0010] Preferably, the movable plate is slidably connected to the limiting groove, and the top of both the first mounting plate and the second mounting plate is provided with a mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When using this equipment, the meshing of the first and second bevel gears through the adjustment mechanism allows the rotation of the threaded rod to drive the lifting block to rise and fall. The lifting block then drives the first or second moving frame to rise and fall. The first or second moving frame moves the second mounting plate closer to or further away from the first mounting plate, thereby adjusting the distance between the power batteries in the mounting slot. It can be flexibly adjusted according to actual usage needs. The shell has good adaptability. When facing power batteries of different specifications and sizes, there is no need to specially customize corresponding combination shells, which greatly reduces production and manufacturing costs and design cycle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 A combined housing for a power battery includes a housing 1. Rectangular grooves 2 are formed on the inner walls of both sides of the housing 1. A rectangular plate 3 is fixedly connected in the rectangular grooves 2. Fixing frames 4 are fixedly connected to the rectangular grooves 2 on both sides. A first mounting plate 5 is arranged between the fixing frames 4. A first movable frame 6 and a second movable frame 7 are respectively arranged above and below the fixing frames 4. The distance between the first movable frame 6 and the second movable frame 7 relative to the fixing frames 4 can be adjusted.

[0022] A second mounting plate 8 is provided between the first movable frame 6 and the second movable frame 7. A first bevel gear 9 and a second bevel gear 10 are provided in a rectangular groove 2 on one side. An adjustment mechanism is provided in the housing 1 to raise and lower the first movable frame 6 and the second movable frame 7 through the first bevel gear 9 and the second bevel gear 10. The distance between the second mounting plate 8 and the first mounting plate 5 is adjusted by the movement of the first movable frame 6 and the second movable frame 7 through the adjustment mechanism.

[0023] The adjustment mechanism includes a rotating rod 11 rotatably connected to the housing 1 and symmetrically arranged. A knob 12 is fixedly connected to one end of the rotating rod 11. The other end of the rotating rod 11 is fixedly connected to the first bevel gear 9. Threaded rods 13 are rotatably connected to the top and bottom of the rectangular plate 3. One end of the threaded rod 13 is fixedly connected to the second bevel gear 10. The second bevel gear 10 meshes with the first bevel gear 9. Through the meshing of the first bevel gear 9 and the second bevel gear 10, when the rotating rod 11 is turned, it can drive the threaded rod 13 to rotate.

[0024] It should be noted that a limit pin is provided at the connection between the rotating rod 11 and the housing 1. After the first moving frame 6 and the second moving frame 7 move to the appropriate position, the limit pin limits the rotating rod 11 to prevent the rotating rod 11 from continuing to rotate.

[0025] The threaded rod 13 is threadedly connected to a lifting block 14. The lifting block 14 is fixedly connected to one side of the first movable frame 6 and the second movable frame 7 respectively. The rotation of the threaded rod 13 allows the lifting block 14 to move the first movable frame 6 or the second movable frame 7 closer to or away from the fixed frame 4.

[0026] A sliding rod 15 is fixedly connected in a rectangular groove 2 on one side. A moving block 16 is fixedly connected to one side of the first moving frame 6 and the second moving frame 7. The moving block 16 is slidably connected to the sliding rod 15. Through the sliding rod 15 and the moving block 16, the first moving frame 6 and the second moving frame 7 can maintain balance on both sides when they are raised and lowered.

[0027] The fixed frame 4, the first movable frame 6, and the second movable block 16 are all provided with limit grooves 17. Limit rods 18 are fixedly connected in the limit grooves 17. Movable plates 19 are fixedly connected to both sides of the first mounting plate 5 and the second mounting plate 8. The movable plates 19 are slidably connected to the limit rods 18. A handle 20 is fixedly connected to one side of the first mounting plate 5 and the second mounting plate 8. By pulling the handle 20, the first mounting plate 5 or the second mounting plate 8 can be pulled out, making it convenient to install the power battery onto the first mounting plate 5 and the second mounting plate 8.

[0028] While the movable plate 19 and the limiting rod 18 limit the first mounting plate 5 and the second mounting plate 8, they do not affect the removal of the first mounting plate 5 and the second mounting plate 8.

[0029] The movable plate 19 is slidably connected to the limiting groove 17. The top of the first mounting plate 5 and the second mounting plate 8 are both provided with mounting grooves for installing the power battery.

[0030] A second rectangular groove 2 is provided on one side of the housing 1. A cover plate 21 is connected inside the second rectangular groove 2. The second rectangular groove 2 and the cover plate 21 are provided with threaded holes. A fixing bolt is threaded into the threaded holes. The cover plate 21 is installed on one side of the housing 1 through the threaded holes and the fixing bolt. When it is necessary to install or repair the internal power battery, the fixing bolt is removed and the cover plate 21 is removed.

[0031] It should be noted that after the cover plate 21 is closed, one side of the first mounting plate 5 and the second mounting plate 8 are attached to the cover plate 21, while the other side is attached to the inner wall of the housing 1, so as to prevent the first mounting plate 5 and the second mounting plate 8 from shaking back and forth inside the housing 1.

[0032] Heat dissipation holes 22 are provided on both sides of the housing 1, and a wiring port is provided on one side of the housing 1. Heat dissipation is provided inside the housing 1 through the heat dissipation holes 22, and the power battery inside can transmit power to the outside of the housing 1 through the wiring port.

[0033] The working principle of this utility model:

[0034] When it is necessary to install the power battery into the housing 1, open the cover 21, pull out the first mounting plate 5 or the second mounting plate 8 through the handle 20, and install the power battery into the mounting slot.

[0035] Meanwhile, when it is necessary to adjust the distance between the first mounting plate 5 and the second mounting plate 8, turn the knob 12. The knob 12 drives the rotating rod 11 to rotate, the rotating rod 11 drives the first bevel gear 9 to rotate, the first bevel gear 9 drives the second bevel gear 10 to rotate, the second bevel gear 10 drives the threaded rod 13 to rotate, the threaded rod 13 drives the lifting block 14 to rise and fall, the lifting block 14 then drives the first moving frame 6 or the second moving frame 7 to rise and fall, the first moving frame 6 or the second moving block 16 drives the second mounting plate 8 to move closer to or further away from the first mounting plate 5;

[0036] Finally, after installing all three power batteries into the second rectangular slot 2 and adjusting the position of the second mounting plate 8, the cover plate 21 is fixed into the second rectangular slot 2 using fixing bolts.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
