Description

Technical Field

[0001] This invention relates to the field of batteries, and more particularly to a battery module and a battery. Background Technology

[0002] In the battery industry, support components are used to support and hold electrical connectors, such as copper busbars, so that the electrical connectors are kept in the right position and to prevent displacement and short circuits.

[0003] The current support assembly includes an end plate and an output pole support mounted on the end plate. After the electrical connector is installed on the output pole support, the output pole support is sandwiched between the end plate and the electrical connector. All sides of the output pole support are surrounded by the end plate, and the electrical connector is fixed relative to the end plate. This means that the output pole support cannot be removed vertically or horizontally without removing the electrical connector. If the output pole support is damaged, the electrical connector must be completely removed before the output pole support can be taken out, which makes the replacement of the output pole support quite troublesome.

[0004] Therefore, it is necessary to design a battery module and battery that makes it easier to replace the output terminal support. Summary of the Invention

[0005] The purpose of this invention is to provide a battery module and battery that makes it easier to replace the output terminal support.

[0009] The end plate has a mounting groove, in which the output electrode support is installed; the front wall of the mounting groove forms a hollow groove, and the output electrode support can slide out of the mounting groove along a first direction, and the front wall forms a limiting protrusion for stopping the limiting shoulder;

[0010] The slider slides into the mounting groove in the opposite direction of the first direction and elevates the output pole support so that the limiting protrusion stops the limiting shoulder; the slider can slide out of the mounting groove from the hollow groove in the first direction.

[0011] Optionally, the output pole support further includes an elastic snap-fit ​​portion;

[0012] The slider is provided with a snap-fit ​​slot for snap-fit ​​connection with the elastic snap-fit ​​part;

[0016] The elastic buckle is pushed and elastically deformed to allow it to enter the through groove.

[0017] Optionally, the groove extends toward the front wall so that the resilient latch portion is exposed to the outside.

[0018] Optionally, two buckle slots are provided, and two elastic buckle portions are provided corresponding to the buckle slots;

[0019] The elastic buckle portion passes through the buckle slot, and the two elastic buckles elastically engage the slider.

[0020] Optionally, the elastic buckle extends into one side of the bottom of the slider, and the front wall is provided with a through groove for the elastic buckle to slide out along the first direction.

[0021] Optionally, the mounting groove includes a slide groove and a receiving groove located on one side of the top of the slide groove for mounting the output pole support, and the width of the slide groove is greater than the width of the receiving groove;

[0028] A battery comprising a battery module as described in any of the preceding claims.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In this embodiment, when it is necessary to remove the output electrode support, the slider can be pushed out of the mounting groove along the first direction first, and then the output electrode support can be moved towards the mounting groove until the limiting shoulder is no longer blocked by the limiting protrusion.

[0044] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0047] This invention provides a battery module for enabling the detachable installation of the output electrode support 1, making the replacement of the output electrode support 1 more convenient.

[0048] Please see Figures 1 to 10 The battery module includes an output electrode support 1, an end plate 2, and a slider 3. Among them:

[0049] The output pole support 1 includes a main body 11, and a limiting shoulder 12 is provided on at least one side of the main body 11. Preferably, as shown in the figure... Figure 1 , Figure 4 As shown, limit shoulders 12 are provided on both sides of the main body 11.

[0050] The end plate 2 has a mounting groove 21, and the output pole support 1 is installed in the mounting groove 21. The front wall of the mounting groove 21 forms a hollow groove 22, and the output pole support 1 can slide out of the mounting groove 21 from the hollow groove 22 along the first direction. The front wall also forms a limiting protrusion 23 for stopping and limiting the shoulder 12.

[0051] The slider 3 slides into the mounting groove 21 in the opposite direction of the first direction and raises the output pole support 1 so that the limiting protrusion 23 stops the limiting shoulder 12; the slider 3 can slide out of the mounting groove 21 from the hollow groove 22 in the first direction.

[0052] The steps for removing the output electrode support 1 that needs to be replaced are as follows: push the slider 3 so that the slider 3 slides out of the mounting slot 21 from the hollow groove 22 along the first direction. At this time, the output electrode support 1 will fall downward, thereby causing the limiting shoulder 12 and the limiting protrusion 23 to be misaligned. At this time, the limiting protrusion 23 no longer restricts the limiting shoulder 12, and the output electrode support 1 can slide out of the mounting slot 21 from the hollow groove 22 along the first direction, so that the output electrode support 1 that needs to be replaced can be easily removed.

[0053] The installation steps for installing the new output electrode support 1 are as follows: slide the new output electrode support 1 from the hollow groove 22 into the mounting groove 21 in the opposite direction of the first direction, and then slide the slider 3 between the bottom of the mounting groove 21 and the bottom of the output electrode support 1 in the opposite direction of the first direction. The slider 3 raises the output electrode support 1, so that the limiting protrusion 23 constitutes a limiting effect on the limiting shoulder 12, preventing the output electrode support 1 from sliding out of the mounting groove 21 from the hollow groove 22 in the first direction, thus completing the installation.

[0054] In this embodiment, the battery module can be disassembled and installed without removing the copper busbars and other electrical connectors, which effectively simplifies disassembly and installation and improves maintenance efficiency.

[0055] It should also be noted that the output pole support 1 generally protrudes from the opening of the mounting groove 21 to support the electrical connector. The pressure of the electrical connector is generally vertically downward, so the pressure on the slider 3 is also vertically downward. When the slider 3 has a plate-like structure, the friction between the slider 3 and the bottom of the mounting groove 21 will keep the slider 3 in position and prevent it from sliding out of the mounting groove 21; that is, without external force, the slider 3 will not slide out of the mounting groove 21 in the first direction.

[0056] Optionally, the output pole support 1 further includes an elastic snap-fit ​​part 13; the slider 3 is provided with a snap-fit ​​slot 31 for snap-fit ​​connection with the elastic snap-fit ​​part 13; the elastic snap-fit ​​part 13 can be pushed and elastically deformed to disengage the slider 3 from the output pole support 1.

[0057] Specifically, the elastic latching part 13 and the latching slot 31 further increase the installation stability between the slider 3 and the mounting groove 21, thereby preventing the slider 3 from sliding out of the mounting groove 21 due to excessive vibration. In addition, the latching slot 31 can also effectively position the output pole support 1, preventing the output pole support 1 from being installed in the wrong position, and has a certain degree of foolproof function. After the slider 3 is disconnected from the output pole support 1, the slider 3 can slide out of the mounting groove 21 from the hollow groove 22 along the first direction. During the sliding process, the elastic latching part 13, after elastic deformation, will not constitute an obstacle to the slider 3 sliding along the first direction.

[0058] Optionally, the slider 3 is provided with a groove 32, and the latching slot 31 includes a through groove 33 for the elastic latching part 13 to pass through in a first direction; the groove 32 has a positioning groove wall 321 away from the front wall. When the elastic latching part 13 is inserted into the latching slot 31, the elastic latching part 13 abuts against the positioning groove wall 321, thereby limiting the position of the slider 3. At this time, the output pole support 1, the end plate 2 and the slider 3 are locked together, effectively improving the structural strength of the battery module. When it is necessary to disassemble the slider 3, the elastic latching part 13 is pushed to deform elastically, so that the elastic latching part 13 enters the through groove 33. At this time, the slider 3 can be directly pushed or pulled to slide out of the mounting groove 21 in the first direction.

[0059] Optionally, the groove 32 extends towards the front wall so that the elastic latch 13 is exposed to the outside, that is, the side opening of the groove 32 connects to the hollow groove 22. Specifically, maintenance personnel can push the elastic latch 13 to elastically deform from the outside using an adjusting rod, thereby pushing the elastic latch 13 into the through groove 33, reducing the difficulty of disassembling the slider 3.

[0060] Optionally, there are two latch slots 31, and two elastic latching parts 13 are provided corresponding to the latch slots 31; the elastic latching parts 13 pass through the latch slots 31, and the two elastic latching parts 13 elastically clamp the slider 3.

[0061] On the one hand, the two elastic snap-fit ​​parts 13 can better fulfill the function of positioning the main body part 11; on the other hand, the two elastic snap-fit ​​parts 13 can improve the stability of the snap-fit ​​connection and increase the structural strength.

[0062] Optionally, the elastic latching part 13 extends into one side of the bottom of the slider 3, and the front wall is provided with a through groove 201 for the elastic latching part 13 to slide out in the first direction. The elastic latching part 13 protrudes from one side of the bottom of the slider 3, which makes it convenient for maintenance personnel to adjust the degree of elastic bending and position of the elastic latching part 13, and to observe the specific position of the elastic latching part 13 to confirm whether the elastic latching part 13 is in a latched locked state or a state that can be slid out.

[0063] Of course, it needs to be added that the elastic buckle 13 can extend into the bottom side of the slider 3 or not. If the elastic buckle 13 extends into the bottom side of the slider 3, the structure of the battery module needs to be improved so that maintenance personnel can adjust the elastic deformation state of the elastic buckle 13. For example, an adjustment groove is provided horizontally on the slider 3, and the adjustment rod can be inserted into the adjustment groove to change the buckling state of the elastic buckle 13.

[0064] Optionally, the mounting groove 21 includes a sliding groove 211 and a receiving groove 212 located on one side of the top of the sliding groove 211 for mounting the output pole support 1, and the width of the sliding groove 211 is greater than the width of the receiving groove 212; in a cross-section perpendicular to the first direction, the cross-sectional shape of the slider 3 is consistent with the cross-sectional shape of the sliding groove 211. Specifically, the width here is Figure 3 The values ​​are displayed horizontally from left to right, while the values ​​are displayed vertically from top to bottom.

[0065] The width of the slide groove 211 is greater than the width of the receiving groove 212, so that the slider 3 in the slide groove 211 cannot move up or down in the vertical direction, further limiting the position of the slider 3. Combined with the setting of the elastic buckle part 13, it can further prevent the output pole support 1 from becoming loose.

[0066] Optionally, the hollowed-out groove 22 is inverted T-shaped, including a through horizontal groove 221 and a through vertical groove 222; limiting shoulders 12 are provided on both sides of the main body 11, and the two limiting shoulders 12 are respectively located on the opposite sides of the vertical groove 222; the limiting protrusion 23 is located on the top side of the horizontal groove 221; the height of the limiting shoulder 12 is less than the height of the horizontal groove 221.

[0067] It should be noted that the perforated groove 22 penetrates the front wall, and the vertical groove 222 allows the main body 11 to pass through. The sliding groove 211 refers to the groove located inside the end plate 2; similarly, the mounting groove 21 is also a groove inside the end plate 2. Since the height of the limiting shoulder 12 is less than the height of the horizontal groove 221, after the output electrode support 1 falls to the bottom of the groove, the limiting shoulder 12 can pass through the horizontal groove 221, thereby allowing the output electrode support 1 to slide out along the first direction, and then slide out of the mounting groove 21 through the perforated groove 22.

[0068] Optionally, the output pole support 1 is provided with a threaded connection hole 101; a threaded connector for fixing an electrical connector is installed in the threaded connection hole 101. The threaded connector is used to fix the electrical connector, and when it is necessary to disassemble the output pole support 1, the threaded connector in the threaded connection hole 101 must be removed first. For example, the first electrical connector and the second electrical connector are stacked on one side of the top of the output pole support 1, and the threaded connector fixes the first connector and the second connector to the main body 11.
