[0039] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be described clearly and completely below by combining with the drawings in the utility model embodiment. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the utility model protection.

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the utility model. In addition, the utility model can refer to the same number and / or letter in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0041] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0042] In related technologies, battery module structure designs, such as those involving components like battery cells and nickel sheets, typically require complex fixing devices, such as screws and nuts. This not only increases structural complexity but also limits design flexibility. To address these technical issues, this invention proposes a fixing bracket that optimizes the mounting bracket to achieve rapid, accurate, and low-cost installation of the battery cell protection board. The battery cell protection board is pushed in through the guide slot of the guide groove, and preliminary positioning and pre-fixation are achieved through the cooperation of the support slot. For product designs with compact space and dense electronic components, the cooperation of the support slot and guide slot ensures stable fixing of the battery cell protection board even in situations with insufficient space, meeting the requirements for product miniaturization.

[0043] In some exemplary embodiments, such as Figures 1-5 As shown, a fixing bracket is used in a battery module to clamp the cell protection board 1, thereby improving the stability and installation efficiency of the cell protection board 1.

[0044] The cell protection board 1 has a first horizontal direction (refer to) Figure 1 The X-axis (as shown) and the second horizontal direction (refer to) Figure 1 The Y-axis shown is perpendicular to the first horizontal direction and the second horizontal direction, and both are perpendicular to the thickness direction of the cell protection board 1 (refer to the Y-axis). Figure 1 (The Z-axis is shown).

[0045] The fixing support comprises a support base 2 and a clamping structure 3 arranged on the support base 2. The support base 2 is made of a plastic material with high strength, good toughness and chemical corrosion resistance, such as ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate) or PA (nylon), to meet the use requirements of the support base 2 in the battery module environment.

[0046] The clamping structure 3 can be integrally formed with the support base 2, eliminating the assembly gap and looseness problems that may be caused by traditional split assembly, thereby significantly improving the reliability of the connection. In the manufacturing process such as injection molding or die casting, the molding of the support base 2 and the clamping structure 3 can be completed at one time, ensuring the close combination between the two. The same material is used between the clamping structure 3 and the support base 2, and they are seamlessly connected, so that the integrally formed fixing support is more solid in overall structure and can withstand greater external force without being easily deformed or damaged.

[0047] Alternatively, in order to meet the clamping requirements of different battery modules or cell protection plates 1, the clamping structure 3 and the support base 2 can also be designed in a split assembly form. This design allows users to select or replace clamping structures 3 of different specifications and shapes according to actual needs, thereby realizing the universality and flexibility of the fixing support. When the clamping structure 3 needs to be replaced or repaired, the entire support base 2 does not need to be replaced, and only the clamping structure 3 part needs to be operated separately, which greatly reduces the cost and time consumption and realizes the convenience in production and maintenance.

[0048] The clamping structure 3 comprises a support fixing part 31 and a guide fixing part 32. The support fixing part 31 is provided with a support groove 311, and a first slot 3111 of the support groove 311 is arranged towards the first horizontal direction. The support groove 311 extends along the second horizontal direction. The design of the support groove 311 should consider the tolerance range of the cell protection plate 1 to ensure that it can be stably embedded and supported, and the first slot 3111 can facilitate the cell protection plate 1 to enter the support groove 311 for support and clamping.

[0049] The guide fixing part 32 is provided with a guide groove 321, and the guide groove 321 has a guide slot 3211 and a support slot 3212. The guide groove 321 extends along the first horizontal direction, the guide slot 3211 is arranged towards the first horizontal direction, and the support slot 3212 is arranged towards the second horizontal direction. The guide slot 3211 and the support slot 3212 are communicated to facilitate the insertion of the cell protection plate 1. The width and depth of the guide groove 321 need to be accurately designed according to the thickness and installation requirements of the cell protection plate 1 to ensure that the cell protection plate 1 can smoothly slide along the groove without jamming or excessive wear.

[0050] The cell protection plate 1 is aligned along the side edge of the second horizontal direction to the guide fixing part 32, enters into the guide groove 321 through the guide notch 3211, and is gently pushed to slide on the guide groove 321 through the support notch 3212. With the sliding of the cell protection plate 1, the other side edge gradually approaches the support fixing part 31, and is embedded into the support groove 311 through the first notch 3111.

[0051] When the cell protection plate 1 is completely in place, the support fixing part 31 and the guide fixing part 32 jointly act to stably clamp the cell protection plate 1 in the fixing support, which not only ensures the stability of the cell protection plate 1 in the horizontal direction (X axis and Y axis), but also limits the movement of the cell protection plate 1 in the thickness direction (Z axis). In order to further improve the fixing effect, the support seat 2 is provided with a fastening structure 26 to fix the cell protection plate 1 and ensure that the cell protection plate 1 does not move. Exemplarily, the fastening structure 26 includes a third fastener 261 and a support connecting column 262, the support connecting column 262 is provided with a fastening hole 2621, the cell protection plate 1 is provided with a corresponding through hole 11, the third fastener 261 is fixedly connected through the through hole 11 and the fastening hole 2621, thereby forming a fixation to the cell protection plate 1, and further improving the stability of the cell protection plate 1. The outer side wall of the support connecting column 262 can also be provided with a reinforcing rib 2622 to improve the strength of the support connecting column 262. Among them, the third fastener 261 is a screw, and the fastening hole 2621 is a screw hole. The screw is screwed with the screw hole to improve the convenience of installation and disassembly. The fastening structure 26 can be provided with two, which are arranged on both sides along the second horizontal direction to balance the pressing and supporting of the cell protection plate 1 and improve the stability of the cell protection plate 1.

[0052] The fixing support in the embodiment effectively improves the stability and installation convenience of the cell protection plate 1 in the battery module, and provides a strong guarantee for the safe operation of the battery module.

[0053] In the embodiment, as shown in Figures 1-5 The guide fixing part 32 includes a first guide clamping body 322 and a second guide clamping body 323, and the split design allows the first guide clamping body 322 and the second guide clamping body 323 to be separately arranged on both sides of the support seat 2 along the second horizontal direction, i.e. on both sides of the cell protection plate 1, thereby providing a double-sided guide and clamping function.

[0054] The first guide clamping body 322 and the second guide clamping body 323 can be tightly connected with the support seat 2 by means of integrated injection molding, to ensure the stability of the entire fixing support.

[0055] The first guide clamping body 322 and the second guide clamping body 323 are each provided with a guide groove 321. The guide groove 321 is, for example, C-shaped, facilitating quick installation and disassembly of the battery protection plate 1, providing a clear sliding path for the battery protection plate 1, and automatically correcting the position of the battery protection plate 1 when the battery protection plate 1 is inserted, ensuring that the battery protection plate 1 is accurately positioned.

[0056] The upper edge and the lower edge of the guide groove 321 are each provided with an inwardly inclined guide surface 3213, further correcting the path and position of the battery protection plate 1 to ensure that the battery protection plate 1 is correctly inserted into the guide groove 321. The C-shaped guide groove 321 can have a certain elasticity, which can absorb the impact force and vibration generated during the insertion of the battery protection plate 1 to some extent, thereby protecting the battery protection plate 1 from damage. For example, the groove width of the guide groove 321 can be 0.2 mm wider than the thickness of the battery protection plate 1, with 0.1 mm reserved on one side to achieve an assembly gap. For example, if the thickness of the battery protection plate 1 is 1.6 mm, the groove width of the guide groove 321 is 1.8 mm.

[0057] During installation, the battery protection plate 1 is first guided and gently pushed into the C-shaped guide groove 321 of the first guide clamping body 322 and the C-shaped guide groove 321 of the second guide clamping body 323 until the front edge touches the support seat 2 or the support structure on the other side until it is fully positioned.

[0058] In this embodiment, as shown in Figures 1-5 The first guide clamping body 322 is provided with an avoidance break 3221. The shape and size of the avoidance break 3221 are accurately designed according to the specific structure (such as a protrusion, a terminal post, etc.) that needs to be avoided on the battery protection plate 1 to ensure that these sensitive parts are not pressed or damaged during clamping. For example, if the edge of the battery protection plate 1 has a protruding terminal, the avoidance break 3221 is designed as an opening matching the shape of the terminal to achieve avoidance. The design of the avoidance break 3221 is not limited to a single shape and size, but can be customized and adjusted according to different models and specifications of the battery protection plate 1 to meet various avoidance needs, ensuring the wide applicability and efficiency of the clamping structure 3.

[0059] The first guide clamping body 322 extends along the first horizontal direction until it extends to the support fixing part 31 and is fixedly connected thereto, forming an L-shaped structure, which not only enhances the overall stability of the clamping structure 3, but also improves the clamping force and uniformity on the battery protection plate 1 by increasing the support area. Alternatively, the support fixing part 31 can also be fixedly connected with the second guide clamping body 323 to form an L-shaped structure, which significantly improves the stability and strength of the clamping structure 3, enabling it to withstand greater external forces and vibrations and ensuring the stable clamping of the battery protection plate 1 under complex working conditions. Alternatively, the support fixing part 31 can be connected with the first guide clamping body 322 and the second guide clamping body 323 at the same time to form a U-shaped structure, which improves the overall strength and clamping force of the clamping structure 3. The construction of the U-shaped structure enables the clamping structure 3 to have high stability and strength in multiple directions, better coping with challenges under complex working conditions.

[0060] Through the design of the double guide clamping body, the force received by the battery protection plate 1 during clamping is more uniform and dispersed, reducing the risk of excessive force on a single point and improving the comfort and safety of clamping.

[0061] In this embodiment, as shown in Figures 1-5 The support seat 2 includes a first support body 21, a second support body 22, and a support frame 23. The first support body 21 and the second support body 22 are arranged opposite to each other along the second horizontal direction, and the first support body 21 is connected with the second support body 22 through the support frame 23, ensuring the stable connection between the two support bodies.

[0062] The first support body 21 is in a plate-shaped structure, which has sufficient rigidity and stability to support the force during clamping. The thickness of the first support body 21 and the second support body 22 can be the same or different, for example, the thickness of the first support body 21 is greater than that of the second support body 22, to achieve increased overall stability of the fixed bracket, optimized weight distribution, or to meet specific clamping requirements.

[0063] The second support body 22 is in a plate-shaped structure and is arranged opposite to the first support body 21, but its thickness is less than that of the first support body 21. This differential thickness design not only reflects the flexibility of the design, but also may help to reduce material costs or meet specific space limitation requirements.

[0064] The first guide clamping body 322 is provided on the first support body 21, and the first guide clamping body 322 is responsible for guiding and clamping one side of the target object, i.e. the battery protection plate 1. Its design should ensure that the contact surface with the battery protection plate 1 is flat and smooth to reduce friction and damage.

[0065] The second guiding and clamping body 323 is arranged on the second support body 22, and the support fixing part 31 is arranged on the support frame 23. The second guiding and clamping body 323 has a function similar to that of the first guiding and clamping body 322, and together realizes stable clamping of the target object.

[0066] The support fixing part 31 is arranged on the support frame 23, and the support fixing part 31 can further reinforce the effect of the clamping structure 3.

[0067] Through the design of the support body with different thicknesses, the clamping structure 3 enhances its stability and load-bearing capacity while maintaining a compact overall structure. Under the premise of not affecting the overall performance, by reducing the material usage of the thinner support body, it helps to reduce the production cost.

[0068] After installation is completed, the position of the battery protection plate 1 is checked to ensure that it is completely embedded and does not shake. If necessary, the fastening force of the support fixing part 31 and the guiding fixing part 32 can be adjusted to achieve the best clamping effect. The support fixing part 31 is also C-shaped, for example, so that the battery protection plate 1 can be embedded into the support fixing part 31 to be clamped and supported.

[0069] In this embodiment, as shown in Figures 1-5 The support frame 23 includes a first frame body 231, a second frame body 232, and a first fastener 233. The first frame body 231 has a certain load-bearing and force-transmitting capacity, and is provided with a first through hole 2311.

[0070] The second frame body 232 is arranged opposite to the first frame body 231 and also bears the task of supporting and transmitting force. The second frame body 232 is provided with a second through hole 2321, for example, and the first through hole 2311 of the first frame body 231 is connected with the second through hole 2321 of the second frame body 232 through the first fastener 233. The first fastener 233 passes through the first through hole 2311 and the second through hole 2321, and is connected with the two frame bodies together through thread locking, bolt and nut cooperation or other fastening methods. The selection and installation of the fastener need to ensure the strength and stability of the connection to meet the use requirements of the support frame 23.

[0071] The first frame body 231 and the second frame body 232 are respectively provided with a support fixing part 31. The support fixing parts 31 are arranged in abutment, that is, their abutment surfaces match each other to ensure that a continuous and stable clamping area can be formed during clamping operation.

[0072] The specific design of the support fixing part 31 should take into account factors such as the shape, size and material of the clamped object to ensure the firmness and reliability of clamping. At the same time, in order to reduce the damage to the clamped object (i.e. the battery protection plate 1), the contact surface of the support fixing part 31 is usually made of soft material or is specially treated.

[0073] In the embodiment, as shown in Figures 1-5 The first support body 21 has sufficient strength and stability to support the load above or around it, and is provided with at least one third through hole 211 for connecting with the second support body 22. Corresponding to the first support body 21, the second support body 22 is also designed to have sufficient support capacity. The second support body 22 is provided with at least one fourth through hole 221, and the third through hole 211 of the first support body 21 is connected with the fourth through hole 221 of the second support body 22 through the second fastener 24.

[0074] In some examples, in order to enhance the stability and distribution of the connection force, the first support body 21 is provided with two first connecting columns 212, which are arranged on both sides in the vertical direction, and the third through hole 211 is arranged in the first connecting column 212. The above arrangement not only facilitates the passage of the second fastener 24, but also effectively disperses the stress at the connection, improving the durability of the overall structure.

[0075] The second support body 22 is provided with two second connecting columns 222, which are arranged on both sides in the vertical direction, and the fourth through hole 221 is arranged in the second connecting column 222. Such a layout ensures accurate alignment with the first connecting column 212 and the third through hole 211 on the first support body 21, providing convenience for subsequent connection operations.

[0076] The second fastener 24 is provided with two, and is arranged one by one with the second connecting column 222 and the first connecting column 212, so as to realize firm connection. For example, the two second fasteners 24 are arranged one by one with the two first connecting columns 212 and the third through holes 211 in the first connecting columns 212 on the first support body 21, and the two second connecting columns 222 and the fourth through holes 221 in the second connecting columns 222 on the second support body 22. During installation, the second fastener 24 is passed through the corresponding third through hole 211 and fourth through hole 221, and the two are tightly connected together through appropriate fastening methods (such as threaded locking, riveting, etc.).

[0077] Among them, the first support body 21 is thick, which can be provided with an avoiding hole 213 to facilitate the passage of the second fastener 24 and to shield the second fastener 24.

[0078] Through the above design, the embodiment successfully realizes the firm connection between the first support body 21 and the second support body 22. The connection structure not only has high bearing capacity and anti-deformation capacity, but also effectively disperses the stress at the connection through reasonable layout and selection of fasteners, prolonging the service life of the overall structure. In addition, the structure also has the advantages of easy installation and maintenance, which provides great convenience for practical application.

[0079] In the embodiment, as shown in Figures 1-6 The support base 2 includes a support bottom plate 25, and one support bottom plate 25 can be arranged on the first support body 21 and the second support body 22, and the two support bottom plates 25 are butted to form a complete flat plate, thereby providing powerful support and fixation for the battery cell protection plate 1. The fastening structure 26 is arranged on the support bottom plate 25 to play a supporting role.

[0080] In the related art, the fixing mode can cause the battery cell protection plate 1 to deform due to stress generated by screw tightening, thereby affecting the performance of the electronic components thereon. In the utility model, the double fixing mode of the support groove 311, the guide groove 321 and the fastening structure 26 effectively disperses the stress, reduces the risk of deformation of the battery cell protection plate 1, and guarantees the long-term stability and reliability of the product. The fixing bracket can be arranged in the box body 4 to realize the flatness of the appearance of the battery module, and the actual situation is specific.

[0081] The utility model also provides a battery module, which comprises a battery cell protection plate and a fixing bracket as in the above embodiment, so as to effectively fix and protect the battery cell protection plate.

[0082] The battery cell protection plate is an important component in the battery module, and is responsible for monitoring and managing key parameters such as voltage, current and temperature of the battery cell, to ensure the safe and stable operation of the battery. The fixing bracket has a specific structure according to the description of the foregoing embodiment, and is used to stably clamp the battery cell protection plate in the fixing bracket to prevent movement or vibration of the battery cell protection plate during operation, thereby guaranteeing the overall performance and reliability of the battery module.

[0083] By adopting the fixing bracket of the embodiment, the battery cell protection plate is effectively fixed and protected. The design of the fixing bracket not only guarantees the stability of the battery cell protection plate in the module, but also provides necessary support and protection for the battery cell protection plate, reduces the risk of damage caused by vibration or impact. At the same time, the structure also simplifies the assembly process of the battery module, and the production operation is simple, which can save the amount of third fasteners (material cost) and reduce labor, improve production efficiency and product quality.

[0084] By integrating the battery cell protection plate and the fixing bracket, the battery cell protection plate is effectively fixed and protected. The module has compact structure, stable performance, easy assembly and maintenance, and provides a powerful guarantee for the safe and stable operation of the battery system.
