Description

Technical Field

[0001] This utility model relates to the field of energy storage batteries, and in particular to a combined energy storage battery. Background Technology

[0002] Many electric bicycles use modular energy storage batteries, which typically consist of multiple lithium-ion battery cells to provide enough energy to power the vehicle.

[0003] Patent "202323440065.1" discloses a combined energy storage battery, including an outer shell, separators, inclined rubber, bottom slots, battery bodies, battery connection components, positive terminals, negative terminals, hinges, cover plates, buckles, and latches. The outer shell has three separators inside, each with inclined rubber on both sides, dividing the interior of the outer shell into four placement slots. Each placement slot has a bottom slot at its bottom, where a battery body is secured. Each of the three separators has a sliding groove at one end, where a battery connection component is slidably connected. The four battery bodies are connected by three battery connection components. Each battery connection component includes an insulating shell, a pull rod, a limiting plate, a connecting piece, and a connecting end.

[0004] However, in actual use, energy storage batteries generate a lot of heat during charging and discharging. The outer shell of this patent is relatively sealed. In the sealed space, the heat generated during battery charging and discharging is difficult to dissipate, which may cause the battery temperature to rise, leading to thermal runaway and causing the battery to catch fire or explode.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] When riding an electric bicycle on the road, the battery inside the electric bicycle will vibrate up and down, especially in uneven places such as mountainous areas. As the battery moves up and down, it will drive the upper and lower air inflators at both ends to move. This will change the internal cavity of the upper air inflator and the lower air inflator in the outer box. When the cavity shrinks, air will enter the air guiding component, thereby cooling the surface of the battery and pushing the air to the edge of the outer box. Finally, the air will be discharged from the heat dissipation holes in the front and rear walls of the outer box, thereby reducing the temperature inside the outer box. Attached Figure Description

[0047] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] Given that in current technology, energy storage batteries generate a lot of heat during charging and discharging in actual use, and the outer shell of this patent is relatively sealed, the heat generated during battery charging and discharging is difficult to dissipate within the sealed space, which may lead to an increase in battery temperature, thereby causing thermal runaway and resulting in battery fire or explosion.

[0050] like Figure 1-6 As shown, this utility model embodiment provides a combined energy storage battery, including an outer casing 1, and a battery body 5 installed in the middle of the inner part of the outer casing 1;

[0051] Air blowing assembly 2 is installed at both ends of the battery body 5. Air blowing assembly 2 is used to push the air at the upper and lower ends of the outer casing 1 to the space between the battery body 5. Air blowing assembly 2 is slidably connected to outer casing 1.

[0052] Furthermore, the air-blowing assembly 2 is installed at both ends of the battery body 5. The air-blowing assembly 2 is used to push the air at the upper and lower ends of the outer casing 1 to the space between the battery body 5. The air-blowing assembly 2 is slidably connected to the outer casing 1.

[0053] The air-blowing assembly 2 consists of an upper air-blowing group and a lower air-blowing group. The upper air-blowing group and the lower air-blowing group have the same structure. The upper air-blowing group includes:

[0054] The first mounting plate 201 is slidably connected to the front, rear, left and right side walls of the outer box 1. Multiple return springs 3 are respectively provided between the two first mounting plates 201 and the outer box 1. The surface of the first mounting plate 201 can be reinforced to prevent the first mounting plate 201 from deforming.

[0055] Mounting hole 202 is formed on the outer wall of the first mounting plate 201, and mounting hole 202 is used in conjunction with air blowing assembly 2;

[0056] The second mounting plate 203 is fixedly installed in the middle position of the mounting hole 202;

[0057] Through hole 204 is formed on the outer wall of the first mounting plate 201. Through hole 204 is used in conjunction with the conductive post of the battery body 5.

[0058] Insulating material is pasted at the through hole 204. A sealing rubber ring is fixedly installed on the outer wall of the first mounting plate 201. The first mounting plate 201 of the lower air blower does not have a through hole 204. Insulating material can be pasted on the outer wall of the first mounting plate 201. The insulating material at the through hole 204 can be a wear-resistant insulating rubber material.

[0059] Through the above technical solution:

[0060] When in use, the battery body 5 inside the electric bicycle will vibrate up and down when riding on the road, especially in uneven places such as mountainous areas. Therefore, the battery body 5 will drive the upper and lower air groups at both ends to move during the up and down movement. As a result, the internal cavity of the upper air group and the upper end of the outer box 1 and the lower air group and the lower end of the outer box 1 will change. When the cavity shrinks, air will enter the air guide component 4, thereby cooling the surface of the battery body 5 through the air guide component 4. At the same time, the air is pushed to the edge of the outer box 1 and finally discharged from the heat dissipation holes in the front and rear walls of the outer box 1, thereby reducing the temperature inside the outer box 1.

[0061] Meanwhile, the first mounting plate 201 can press the connecting wire at the position of the conductive post of the battery body 5 to avoid the problem of poor contact between the connecting wire and the conductive post due to loose connecting wire;

[0062] This device is equipped with a sealing rubber ring, which can effectively seal the outer casing 1 and the air blowing assembly 2.

[0063] Specifically, such as Figure 4-5 As shown;

[0064] The air guiding assembly 4 includes:

[0065] A square guide tube 401 is installed in the mounting hole 202, and air outlet holes 4011 are respectively opened on both sides of the square guide tube 401.

[0066] The mounting slots are installed at the middle positions of the upper and lower ends of the square guide tube 401, and the mounting plate 403 is fixedly installed at the lower end of the mounting slot. The mounting plate 403 is fixed to the inner wall of the square guide tube 401.

[0067] Baffle 402 is rotatably mounted on the inner wall of square guide tube 401, and a tension spring 405 is provided between square guide tube 401 and baffle 402;

[0068] Air guiding component 4 is installed between air blowing components 2. Air guiding components 4 are provided on the side walls of the battery body 5. Air guiding components 4 are used to drive the air flow inside the outer casing 1.

[0069] The fixing plate 403 and the second mounting plate 203 are connected by a second screw. The thickness and width of the fixing plate 403 and the second mounting plate 203 can be increased as needed. The fixing plate 403 and the second mounting plate 203 are made of metal material.

[0070] The square guide tube 401 is made of thermally conductive material. The square guide tube 401 is tightly attached to the battery body 5 and does not contact the inside of the outer casing 1.

[0071] Through the above technical solution:

[0072] In use, when air enters the square guide tube 401 from the upper cavity, the air pushes open the baffle 402 at the upper end of the square guide tube 401, allowing air to enter the square guide tube 401. The air pressure inside the square guide tube 401 increases. However, the baffle 402 at the lower end of the square guide tube 401 is blocked by the fixing plate 403, so the air cannot enter the lower cavity. The air will then be discharged from the vent 4011 and enter the middle of the outer casing 1. It will then blow the heat from the surface of the battery body 5 towards the outer casing 1 and finally be discharged from the heat dissipation holes in the front and rear walls of the outer casing 1, thereby reducing the temperature inside the outer casing 1.

[0073] Specifically, such as Figure 3 As shown;

[0074] Auxiliary component 6 includes:

[0075] Sealing plate 601 is installed at the upper and lower air inlet positions of the outer casing 1;

[0076] The limiting post 602 is slidably installed at the corner of the sealing plate 601 and fixedly installed on the inner wall of the outer box 1.

[0077] The first spring 603 is sleeved on the outer wall of the limiting post 602;

[0078] Auxiliary component 6 is installed at the air intake positions at the upper and lower ends inside the outer casing 1. Auxiliary component 6 is used in conjunction with air blower component 2.

[0079] Through the above technical solution:

[0080] When in use, when the space of one of the cavities at the top and bottom of the outer casing 1 increases, the cavity will form a negative pressure. At this time, the baffle 402 that is close to it will be blocked by the fixed plate 403. Therefore, air can only enter from the air inlet at the sealing plate 601, thereby bringing cold air into the interior of the outer casing 1.

[0081] Specifically, such as Figure 1-3 As shown, the end cap at the top of the outer box 1 is installed by the first screw, and the end cap and the outer wall of the outer box 1 are respectively fixedly installed with protrusions 7;

[0082] Fans 8 are installed at the air outlets at both ends of the outer casing 1, and the fans 8 are offset from the air guide assembly 4;

[0083] Through the above technical solution:

[0084] When in use, the fan 8 blows air out of the outer casing 1, thereby further reducing the temperature inside the outer casing 1. Each fan 8 can be switched on and off individually.

[0085] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
