Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery, an electrical device, a battery manufacturing method, and manufacturing equipment. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0004] Battery packs typically include busbars and other electrical connectors to facilitate internal electrical connectivity and connection to the overall electrical system of the battery pack. To ensure the safety of the battery pack under various operating conditions, these busbars and other electrical connectors must be securely fixed. Furthermore, with increasingly higher energy density requirements for battery packs and significantly reduced internal space, securing these connectors within a limited operating space has become a critical challenge. Summary of the Invention

[0005] This application provides an installation device, a battery, an electrical device, a battery manufacturing method, and manufacturing equipment to achieve the installation of electrical connectors within a limited space.

[0006] In a first aspect, this application provides an installation device for a battery, the battery including a housing, the installation device including a base and a bracket, the base being configured to be connected to the housing; the bracket being used to assemble electrical connectors of the battery and being configured to be slidably connected to the base.

[0007] In the technical solution of this application, the installation device includes a base and a bracket. The base is connected to the battery casing, and the battery's electrical connectors are mounted on the bracket. The bracket and base are slidably connected, enabling rapid installation of the electrical connectors. The bracket's slidable connection to the base reduces the operating space required for fixing the electrical connectors, allowing installation within a limited space. Furthermore, it reduces the space occupied by the installation device within the battery casing, improving the space utilization of the battery casing and thus contributing to increased battery energy density.

[0008] In some embodiments, the mounting device further includes a sliding assembly disposed on the base and the bracket, and configured to allow the bracket to slide relative to the base along a first direction, the first direction being the height direction of the battery. By allowing the bracket to slide relative to the base along the first direction using the sliding assembly, the layout characteristics of the control space within the battery casing can be fully utilized, facilitating the installation and positioning of electrical connectors.

[0009] In some embodiments, the sliding assembly includes a sliding guide and a slider. The sliding guide extends along a first direction and is disposed on one of the base and the bracket, while the slider is disposed on the other of the base and the bracket. The slider is slidably engaged with the sliding guide. The engagement of the sliding guide and the slider improves the stability of the bracket sliding relative to the base along the height direction of the battery.

[0010] In some embodiments, the sliding guide is a groove, and the slider is a block adapted to the groove, the block slidingly engaging with the groove. By setting the sliding guide as a groove and the slider as a block, the structure is simple and easy to manufacture, reducing the manufacturing difficulty and cost of the installation device.

[0011] In some embodiments, the mounting device further includes a locking assembly disposed on the base and the bracket, the locking assembly being used to lock the bracket onto the base when the bracket moves relative to the base to a preset position. By locking the bracket onto the base using the locking assembly, the wobbling of the bracket relative to the base is reduced, thereby reducing the wobbling of the electrical connectors within the battery casing and improving battery safety.

[0012] In some embodiments, the locking assembly includes a slot disposed on one of the base and the bracket, and an insert disposed on the other of the base and the bracket, wherein the insert is capable of being inserted into the slot when the bracket moves relative to the base to a preset position. When the bracket slides relative to the base, the insert abuts against the other of the base and the bracket, providing guidance and support for the movement of the bracket relative to the base, mitigating wobbling during sliding, and ensuring that the insert is inserted into the slot at the preset position, thereby effectively locking the bracket to the base.

[0013] In some embodiments, the insert is tilted relative to the sliding direction of the bracket. This reduces the distance between the bracket and the base, and also provides a guiding function, further ensuring that the insert is inserted into the slot at the preset position, thereby effectively locking the bracket onto the base.

[0014] In some embodiments, the free end of the insert is higher than the fixed end of the insert. The insert is tilted relative to the sliding direction of the bracket, and the free end of the insert is higher than the fixed end of the insert, which allows the insert to play a better guiding role and further ensures that the insert is inserted into the slot when in the preset position, thereby effectively locking the bracket to the base.

[0015] In some embodiments, the bracket includes a bracket body and a mounting member. The bracket body is slidably connected to the base, and the mounting member is disposed on the side of the bracket body opposite to the base. The mounting member and the bracket body define an installation space for assembling the electrical connector of the battery. By slidably connecting the bracket body to the base, the bracket can be easily slidably connected to the base as a whole. The mounting member being disposed on the side of the bracket body opposite to the base, and the mounting space defined between the mounting member and the bracket body, facilitates the assembly of the electrical connector on the bracket.

[0016] In some embodiments, the mounting member includes a first portion connected to the side of the bracket body opposite to the base, and a second portion located above and connected to the first portion, wherein the first portion, the second portion, and the bracket body define an installation space for assembling an electrical connector of the battery. By providing the first and second portions to facilitate defining an installation space on the side of the bracket body opposite to the base, the installation of the electrical connector is facilitated.

[0017] In some embodiments, the mounting member further includes a third portion connected to the second portion and extending toward the bracket body. The first portion, the second portion, the third portion, and the bracket body define an installation space for assembling the electrical connector of the battery, and the third portion and the bracket body define an opening through which the electrical connector of the battery passes. By providing the third portion extending toward the bracket body, the displacement of the battery's electrical connector within the installation space along the battery height direction can be limited, reducing the wobbling of the electrical connector in the battery height direction.

[0018] In some embodiments, the free end face of the third portion is an inclined surface, which includes a first edge away from the bottom of the housing and a second edge close to the bottom of the housing. The distance from the first edge to the support body is greater than the distance from the second edge to the support body. With this configuration, when the electrical connector is installed in the installation space, the inclined end face of the free end of the third portion can act as a guide, allowing the electrical connector to slide more smoothly into the installation space through the opening, facilitating the installation and fixation of the electrical connector.

[0019] In some embodiments, a support member is provided on the side of the bracket body opposite to the base, and the support member has a guide surface formed on it for guiding the electrical connector of the battery into the mounting space. The guide surface on the support member can guide the electrical connector of the battery to slide into the bottom of the mounting space, while the support member can abut against the electrical connector of the battery, restricting the movement of the electrical connector of the battery in a direction perpendicular to the height of the battery, so that the electrical connector is more tightly fixed in the mounting space.

[0020] In some embodiments, the support member has a hollow structure that allows the support member to deform so that the electrical connector is secured between the support member and the second portion. This arrangement allows for the installation space to accommodate different types of electrical connectors, thereby improving the applicability of the installation device.

[0021] In some embodiments, the base further includes a support member disposed on the base, the support member being used to support the bracket when the bracket moves relative to the base to a preset position. The support member provides support force while limiting the bracket from continuing to slide along the base, so that the bracket can be stably connected to the base.

[0022] In some embodiments, the base further includes an extension located above and connected to the support member, the extension being used to abut the bracket against the base when the bracket moves relative to the base to a preset position. The extension above the support member restricts movement of the bracket in a direction perpendicular to the battery height, thus securing the bracket completely to the base.

[0023] In some embodiments, the bracket further includes reinforcing ribs disposed between the bracket body and the mounting member to improve the structural strength of the mounting device.

[0024] In a second aspect, this application provides a battery that includes the mounting means described in the first aspect.

[0025] The battery in this embodiment features a mounting device on its casing. The base of the mounting device is connected to the battery casing, and the battery's electrical connectors are mounted on a bracket. The bracket and base are slidably connected, enabling rapid installation of the electrical connectors. The bracket's slidable connection to the base reduces the operating space required for the mounting device to fix the electrical connectors, allowing installation within a limited space. Furthermore, it reduces the space occupied by the mounting device within the battery casing, improving space utilization and thus increasing the battery's energy density.

[0026] Thirdly, this application provides an electrical device that includes the battery described in the second aspect above.

[0027] The electrical device of this application embodiment uses the battery described in the second aspect as a power system. The battery includes a mounting device, which comprises a base and a bracket. The base of the mounting device is connected to the battery casing, and the battery's electrical connectors are mounted on the bracket.

Furthermore, it reduces the space occupied by the mounting device within the battery casing, improving the space utilization of the battery casing, thereby increasing the battery's energy density and extending the device's operating time.

The base of the installation device is connected to the battery casing, and the battery's electrical connectors are mounted on a bracket. The bracket and the base are slidably connected, enabling rapid installation of the electrical connectors.

Furthermore, it reduces the space occupied by the installation device within the battery casing, improving the space utilization of the battery casing and thus contributing to increased battery energy density.

[0030] Fifthly, this application provides a battery manufacturing apparatus, including a first providing device for providing a housing; a second providing device for providing an installation device, the installation device including a base and a bracket; a third providing device for providing electrical connectors; and an assembly device for connecting the base to the housing, the bracket being slidably connected to the base, and the electrical connectors being assembled on the bracket.

[0061] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0066] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0067] The inventors noted that, to achieve circuit connectivity within the battery pack, power battery systems typically use busbars and other electrical connectors as high-voltage connections. These high-voltage busbars are then fixed to the high-voltage connector terminals mounted on the casing to establish the circuit connection between the battery pack and the entire battery system. However, to ensure the safety of the battery pack under various operating conditions, the busbars and other electrical connectors must be secured. Typically, these connectors are fixed inside the battery pack using cable ties, requiring pre-drilling of cable tie holes or the installation of cable tie brackets. This method complicates the battery pack casing or bracket structure and is not a reliable fixation method. On the one hand, loosening may occur under handling, vibration, and impact conditions; on the other hand, the cable ties cause significant wear on the electrical connectors. Furthermore, as the energy density requirements of battery packs increase, the internal space is greatly compressed, making the fixation of electrical connectors within a limited operating space a pressing issue.

[0068] Based on the above problems, the inventors, through in-depth research, designed an installation device comprising a base and a bracket. By connecting the base to the housing and mounting electrical connectors on the bracket, with the bracket slidably connected to the base, the electrical connectors of the battery can be quickly fixed within a limited space.

[0069] The installation device disclosed in this application can be used for batteries including a housing and electrical connectors. It can reduce the operating space required to fix the electrical connectors in the housing, improve the space utilization of the battery housing, and thus improve the energy density of the battery.

[0070] The batteries disclosed in this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. These electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., while spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0071] For ease of explanation, the following embodiments use the electrical device 10 provided in some embodiments of this application as an example.

[0072] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure of a vehicle 10 according to some embodiments of this application. The vehicle 10 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 11, a controller 12, and a motor 13 can be installed inside the vehicle 10. The controller 12 is used to control the power supply from the battery 11 to the motor 13. For example, the battery 11 can be installed at the bottom, front, or rear of the vehicle 10. The battery 11 can be used to power the vehicle 10; for example, the battery 11 can serve as the operating power source for the vehicle 10's electrical system, such as meeting the power requirements for starting, navigation, and operation of the vehicle 10.

[0073] In another embodiment of this application, the battery 11 can not only serve as the operating power source for the vehicle 10, but also as the driving power source for the vehicle 10, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 10.

[0074] Please refer to Figure 2 , Figure 3 , Figure 2 This is a schematic diagram of the battery structure of some embodiments of this application. Figure 3 This is an exploded structural diagram of a battery according to some embodiments of this application. The battery 11 mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells 111 to provide higher voltage and capacity. For example, the battery 11 mentioned in this application may include a battery module or battery pack, etc. The battery 11 may include electrical connectors 200 for electrically connecting battery packs or connecting a battery pack to an electrical device. For example, the battery 11 generally includes a battery case 112 for encapsulating one or more battery cells 111. The battery case 112 can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells 111. Specifically, the battery case 112 may include a cover 1121 and a housing 1122, which are fastened together. The shape of the cover 1121 and the housing 1122 may be determined according to the shape of the combination of multiple battery cells 111.

[0075] Multiple battery cells 111 can be connected in series and / or in parallel via terminals for various applications. In high-power applications such as electric vehicles, the application of battery 11 involves three levels: battery cells 111, battery modules, and battery packs. Battery modules are formed by electrically connecting a certain number of battery cells 111 together and placing them in a frame to protect the battery cells 111 from external shocks, heat, vibration, etc. Battery packs represent the final state of the battery system installed in an electric vehicle. Currently, most battery packs are made by assembling a battery management system (BMS), thermal management components, and other control and protection systems onto one or more battery modules. With technological advancements, the battery module level can be omitted, meaning that battery packs can be formed directly from battery cells 111. This improvement increases the gravimetric and volumetric energy density of the battery system while significantly reducing the number of components. The battery mentioned in this application includes battery modules or battery packs.

[0076] In this application, the battery cell 111 may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to this. The battery cell 111 may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to this. The battery cell 111 is generally divided into three types according to the packaging method: cylindrical battery cells, cuboid / square battery cells, and pouch battery cells, and the embodiments of this application are not limited to this.

[0077] like Figure 2 , Figures 4 to 8 As shown, an embodiment of the first aspect of this application provides an installation device 100 for a battery 11, the battery 11 including a housing 1122. The installation device 100 includes a base 110 and a bracket 120, the base 110 being configured to be connected to the housing 1122; the bracket 120 being used to mount electrical connectors 200 of the battery 11 and being configured to be slidably connected to the base 110.

[0078] Mounting device 100 refers to the mounting structure that fixes the electrical connector 200 inside the battery 11.

[0079] The enclosure refers to the base structure used to support the battery cell 111. It is hollow inside to accommodate the battery cell 111. For example, for a rectangular battery cell 11 enclosure, it includes a frame formed by longitudinal and transverse beams, a base plate, and four side plates connected to the base plate. The enclosure can be a base made of a metal material with a certain strength (such as iron, copper, steel, or alloys) to provide good structural stability and load-bearing capacity. Understandably, the enclosure can also be made of insulating material.

[0080] The base 110 refers to the base structure that fixes the bracket 120 to the casing 1122 of the battery 11. It can be a block structure or a plate structure, preferably a plate structure. For example, the base 110 can be a sheet metal part. The base can be fixed to the casing by welding or gluing.

[0081] The bracket 120 refers to the electrical connector 200 for assembling the battery 11 in this embodiment, and is slidably connected to the base 110. It can be made of plastic, or, depending on actual needs, partly of metal and partly of plastic. It can be a one-piece molded structure, formed by injection molding or other methods.

[0082] In the technical solution of this application, the mounting device 100 includes a base 110 and a bracket 120. The base 110 is connected to the casing 1122 of the battery 11. The electrical connector 200 of the battery 11 is mounted on the bracket 120. The bracket 120 is slidably connected to the base 110, which enables the rapid installation of the electrical connector 200. The bracket 120's slidable connection to the base 110 reduces the operating space required for the mounting device 100 to fix the electrical connector 200, allowing the installation of the electrical connector 200 within a limited space. Furthermore, it reduces the space occupied by the mounting device 100 in the casing 1122 of the battery 11, improving the space utilization rate of the casing 1122, thereby contributing to increased energy density of the battery 11.

[0083] In some embodiments, the electrical connector 200 can be used for electrical connection between battery packs, or it can be connected to a high-voltage connector terminal to achieve circuit connection between the battery pack and the electrical device. For example... Figure 7 As shown, the electrical connector 200 may include a conductive busbar 201, which may be made of copper or aluminum. An insulating layer 202 covers the outside of the conductive busbar to prevent short circuits in the electrical connector 200. The insulating layer 202 may be made of plastic. A wear-resistant tube 203 may be provided on the outside of the electrical connector 200 to reduce wear on the insulating layer 202, thereby preventing short circuits and improving battery safety. The wear-resistant tube 203 may be a wear-resistant braided mesh tube, or other materials; this embodiment does not impose any special limitations on this.

[0084] In some embodiments, such as Figure 8 As shown, the mounting device also includes a sliding assembly 150, which is disposed on the base 110 and the bracket 120 and configured to allow the bracket 120 to slide relative to the base 110 in a first direction, the first direction being the height direction of the battery 11.

[0085] The sliding assembly 150 refers to an assembly for allowing the bracket 120 to slide relative to the base 110 along the height direction of the battery 11. The sliding assembly 150 may include a first component and a second component that are slidably engaged with each other. The first component may be connected to one of the base 110 and the bracket 120, and the second component is connected to the other of the base 110 and the bracket 120.

[0086] The height direction of the battery can also be understood as the height direction of the casing 1122.

[0087] Generally, the lateral operating space between the side wall of the battery housing 1122 and the battery cell 111 is small, while the longitudinal operating space (the longitudinal direction is the height direction of the battery) is large. The electrical connector 200 is generally pressed into the gap between the side wall of the battery housing 1122 and the battery cell 111 from top to bottom along the height direction of the battery housing 1122. The sliding component allows the bracket 120 to slide relative to the base 110 in the first direction, which can make full use of the layout characteristics of the operating space inside the battery housing 1122 and facilitate the installation and positioning of the electrical connector 200.

[0088] In some embodiments, such as Figure 9 , Figure 10 As shown, the sliding assembly 150 includes a sliding guide 151 and a slider 152. The sliding guide 151 extends along a first direction and is disposed on one of the base 110 and the bracket 120. The slider 152 is disposed on the other of the base 110 and the bracket 120. The slider 152 is slidably engaged with the sliding guide 151.

[0089] The sliding guide 151 refers to the structure that slides and engages with the sliding member 152 and guides the sliding member 152 to move along the first direction. It can be a track structure or groove structure, such as a slide rail or slide groove, that is disposed on one of the base 110 and the bracket 120 and extends along the first direction.

[0090] The slider 152 refers to a component that cooperates with the sliding guide 151 and can move along the sliding guide 151. It may be a block structure disposed on the other of the base 110 and the bracket 120, the block structure having protrusions adapted to slide rails or grooves, so that the slider 152 is connected to the sliding guide 151 and can slide along the sliding guide 151.

[0091] The cooperation of sliding guide 151 and slider 152 can improve the stability of the bracket 120 sliding relative to the base 110 along the height direction of the battery 11.

[0092] In some embodiments, the sliding guide 151 is a groove, and the slider 152 is a slider adapted to the groove, with the slider slidably engaging with the groove. This design is simple in structure and easy to manufacture, reducing the manufacturing difficulty and cost of the mounting device 100.

[0093] In some embodiments, such as Figure 8 As shown, the mounting device 100 also includes a locking component 140, which is disposed on the base 110 and the bracket 120. The locking component 140 is used to lock the bracket 120 on the base 110 when the bracket 120 moves relative to the base 110 to a preset position.

[0094] Locking component 140 refers to a structural component used to terminate the sliding of bracket 120 relative to base 110 and to lock bracket 120 onto base 110.

[0095] The bracket 120 can be locked onto the base 110 by the locking component 140, reducing the shaking of the bracket 120 relative to the base 110, thereby reducing the shaking of the electrical connectors within the battery housing 1122 and improving the safety of the battery 11.

[0096] In some embodiments, such as Figure 9 , Figure 10 As shown, the locking assembly 140 includes a slot 141 disposed on one of the base 110 and the bracket 120, and an insert 142 disposed on the other of the base 110 and the bracket 120, wherein the insert 142 is capable of being inserted into the slot 141 when the bracket 120 moves relative to the base 110 to a preset position.

[0097] A slot refers to a groove with a certain depth provided on one of the base 110 and the bracket 120, such as a through groove that penetrates the base 110 or the bracket 120, or a recess that does not penetrate the base 110 or the bracket 120.

[0098] Insert 142 refers to a structural component that engages with a slot to lock the bracket 120 onto the base 110. It has a certain degree of rigidity and elasticity, can undergo local elastic deformation, can be integrally molded with the other of the base 110 and the bracket 120, and can be made of plastic.

[0099] When the bracket 120 slides relative to the base 110, the insert 142 can abut against the other of the base 110 and the bracket 120, which can guide and support the movement of the bracket 120 relative to the base 110, reduce the shaking of the bracket 120 when sliding relative to the base 110, and ensure that the insert 142 is inserted into the slot 141 when in the preset position, thereby effectively locking the bracket 120 on the base 110.

[0100] In some embodiments, such as Figure 10 As shown, the insert 142 is tilted relative to the sliding direction of the bracket 120. On the one hand, this can reduce the distance between the bracket 120 and the base 110. On the other hand, the insert 142 can play a certain guiding role, further ensuring that the insert 142 is inserted into the slot 141 when in the preset position, thereby effectively locking the bracket 120 onto the base 110.

[0101] In some embodiments, such as Figure 10 As shown, the free end of the insert 142 is higher than the fixed end of the insert 142.

[0102] The free end of the insert 142 refers to the end opposite to the fixed end of the insert 142.

[0103] The fixed end of the insert 142 refers to the end of the insert 142 that is connected to the other of the base 110 and the bracket 120.

[0104] The insert 142 is tilted relative to the sliding direction of the bracket 120, and the free end of the insert 142 is higher than the fixed end of the insert 142, which allows the insert 142 to play a better guiding role and further ensures that the insert 142 is inserted into the slot 141 when it is in the preset position, thereby effectively locking the bracket 120 to the base 110.

[0105] In some embodiments, such as Figure 10 As shown, the bracket 120 includes a bracket body 121 and a mounting member 122. The bracket body 121 is slidably connected to the base 110. The mounting member 122 is disposed on the side of the bracket body 121 opposite to the base 110. The mounting member 122 and the bracket body 121 define an installation space for the electrical connector 200 of the battery 11.

[0106] The main body 121 refers to the main part of the support, which is used to connect with the base. It can be a block structure with a hollow structure or a plate structure. It can be made of various materials, such as plastic material with a certain degree of elasticity and rigidity, which can reduce the weight of the support 120.

[0107] The mounting component 122 refers to the part of the bracket 120 used to mount the electrical connector 200. The two parts of the bracket 120 can be an integral molding structure formed by casting, injection molding, etc.; or they can be two separate parts connected and combined. The specific method can be flexibly selected according to the actual cost and process difficulty.

[0108] The bracket body 121 is slidably connected to the base 110, which allows the bracket 120 to be slidably connected to the base as a whole. The mounting component 122 is located on the side of the bracket body 121 away from the base 110. The mounting component 122 and the bracket body 121 define an installation space, which allows the bracket 120 to be easily assembled with the electrical connector 200.

[0109] In some embodiments, such as Figure 10 As shown, the mounting component 122 includes a first portion 1221 connected to the side of the bracket body 121 facing away from the base 110, and a second portion 1222 located above and connected to the first portion 1221. The first portion 1221, the second portion 1222, and the bracket body 121 define an installation space for assembling the electrical connector 200 of the battery 11.

[0110] The first part 1221 can be a plate perpendicular to the height direction of the battery, and the second part 1222 can be a plate parallel to the height direction of the battery and connected to the first part 1221.

[0111] The first part 1221 and the second part 1222 are provided to facilitate the definition of an installation space on the side of the bracket body 121 away from the base 110, which facilitates the installation of the electrical connector 200.

[0112] In some embodiments, such as Figure 10 As shown, the mounting component 122 also includes a third part 1223, which is connected to the second part 1222 and extends toward the bracket body 121. The first part 1221, the second part 1222, the third part 1223 and the bracket body 121 define an installation space for the electrical connector 200 of the battery 11, and the third part 1223 and the bracket body 121 define an opening for the electrical connector 200 of the battery 11 to pass through.

[0113] The third part 1223 can be a plate perpendicular to the height direction of the battery and connected to the second part 1222. The length of the third part 1223 is shorter than the length of the first part 1221, so that an opening is defined between the third part 1223 and the bracket body 121 for the electrical connector 200 of the battery to pass through, so that the electrical connector 200 of the battery 11 can be easily slid into the installation space.

[0114] By providing a third part 1223 extending into the bracket body 121, the displacement of the battery electrical connector 200 located in the installation space along the battery height direction can be limited, reducing the swaying of the electrical connector 200 in the battery height direction.

[0115] In some embodiments, such as Figure 10As shown, the free end face of the third part 1223 is an inclined surface. The inclined surface includes a first edge away from the bottom of the housing 1122 and a second edge near the bottom of the housing 1122. The distance from the first edge to the support body 121 is greater than the distance from the second edge to the support body 121. The inclined surface of the free end face of the third part 1223 serves as a guide, allowing the electrical connector 200 to slide more smoothly into the installation space through the opening, facilitating the installation and fixation of the electrical connector 200.

[0116] In some embodiments, such as Figure 10 , Figure 11 As shown, a support member 123 is provided on the side of the bracket body 121 opposite to the base 110, and a guide surface 1231 is formed on the support member 123 for guiding the electrical connector 200 of the battery 11 to slide into the installation space.

[0117] The support member 123 is a protruding structure located on the side of the support body 121 opposite to the base 110.

[0118] The guide surface 1231 on the support member 123 can guide the electrical connector 200 of the battery 11 to slide into the bottom of the installation space. At the same time, the support member 123 can abut against the electrical connector 200 of the battery 11, restricting the electrical connector 200 of the battery 11 from moving in a direction perpendicular to the height of the battery, so that the electrical connector 200 is more tightly fixed in the installation space.

[0119] In some embodiments, such as Figures 8 to 11 As shown, the support member 123 has a hollow structure, which allows the support member 123 to deform so that the electrical connector 200 is snapped between the support member 123 and the second part 1222.

[0120] The hollow structure can be the space defined between the support member 123 and the bracket body 121, or the support member 123 itself can have a hollow cavity.

[0121] This configuration allows for the installation space to accommodate different types of electrical connectors 200, thereby improving the applicability of the installation device 100.

[0122] In some embodiments, such as Figure 10 As shown, the support member 123 is a semi-circular arc protrusion located on the side of the bracket body 121 facing away from the base 110.

[0123] In some embodiments, such as Figure 11 As shown, the support member 123 is a 1 / 4 arc protrusion located on the side of the bracket body 121 facing away from the base 110.

[0124] In some embodiments, such as Figure 9As shown, the base 110 also includes a support member 131, which is disposed on the base 110 and is used to support the bracket 120 when the bracket 120 moves relative to the base 110 to a preset position.

[0125] The support member 131 refers to the component used to support the weight of the bracket 120 and the electrical connector 200 assembled on the bracket 120. It may be a plate-like structure, disposed on the base 110 and extending in a sliding direction perpendicular to the bracket 120, so as to facilitate support for the bracket 120.

[0126] Considering the large volume of the battery pack on the electrical device 10 (e.g., an electric vehicle) and the large weight of the internal busbars and other electrical connectors 200, this application provides a support member 131 on the base 110. When the bracket 120 moves relative to the base 110 to a preset position, the support member 131 supports the weight of the bracket 120 and the electrical connectors 200. In this way, the support member 131 can provide support force while limiting the bracket 120 from continuing to slide along the base 110, so that the bracket 120 can be connected to the base 110 more stably.

[0127] In some embodiments, such as Figure 9 As shown, the base 110 also includes an extension 132, which is located above and connected to the support 131. The extension 132 is used to make the support 120 abut against the base 110 when the bracket 120 moves relative to the base 110 to a preset position.

[0128] The extension 132 refers to a component used to restrict the movement of the bracket 120 relative to the base 110 in a direction perpendicular to the battery height. For example, the extension 132 may be a plate-like structure disposed at the free end of the support 131, and a groove structure defined between the extension 132, the support 131 and the bracket body 121, which can be engaged in the groove structure when the bracket 120 moves to a preset position.

[0129] The extension 132 above the support 131 restricts the movement of the bracket 120 in a direction perpendicular to the battery height, so that the bracket 120 is completely fixed on the base 110.

[0130] In some embodiments, such as Figure 10 As shown, the bracket 120 also includes a reinforcing rib 124, which is disposed between the bracket body 121 and the mounting member 122.

[0131] The reinforcing rib 124 can be a plate material that is inclinedly disposed between the support body 121 and the mounting member 122. By providing the reinforcing rib 124, the structural strength of the mounting device 100 can be improved.

[0132] Based on the above-described various embodiments, refer to Figures 8 to 10This application discloses an installation device 100. The installation device 100 includes a base 110 and a bracket 120. The base 110 is configured to be connected to a housing 1122. The bracket 120 is used to assemble the electrical connector 200 of the battery 11 and is configured to be slidably connected to the base 110. The installation device 100 also includes a locking assembly 140 disposed on the base 110 and the bracket 120. The locking assembly 140 includes a slot 141 disposed on one of the base 110 and the bracket 120, and an insert 142 disposed on the other of the base 110 and the bracket 120. The insert 142 is capable of being inserted into the slot 141 when the bracket 120 moves relative to the base 110 to a preset position.

[0133] In this embodiment, the base 110 of the mounting device 100 is connected to the housing 1122 of the battery 11. The electrical connector 200 of the battery 11 is mounted on the bracket 120, which is slidably connected to the base 110. The locking component 140 locks the bracket 120 onto the base 110 when the bracket 120 moves relative to the base 110 to a preset position, thus enabling rapid fixing of the electrical connector 200. The slidable connection of the bracket 120 to the base 110 reduces the operating space required for fixing the electrical connector 200, allowing for installation of the electrical connector 200 within a limited space. Furthermore, it reduces the space occupied by the mounting device 100 on the housing 1122 of the battery 11, improving the space utilization of the housing 1122 and thus contributing to increased energy density of the battery 11.

[0134] like Figures 2 to 6 As shown, an embodiment of the second aspect of this application provides a battery 11, which includes the mounting device 100 in the above embodiments.

[0135] There can be one or more mounting devices 100. The specific number can be flexibly set according to the scale of the battery 11.

The slidable connection of the bracket 120 to the base 110 reduces the operating space required for the installation device 100 to fix the electrical connector 200, allowing installation of the electrical connector 200 within a limited space. Furthermore, it reduces the space occupied by the installation device 100 in the housing 1122 of the battery 11, improving the space utilization of the housing 1122 and thus contributing to increased energy density of the battery 11.

[0137] like Figure 1As shown, an embodiment of the third aspect of this application provides an electrical device that includes the battery 11 in the above embodiments.

The battery 11 includes a mounting device 100, which includes a base 110 and a bracket 120. The base 110 of the mounting device 100 is connected to the housing 1122 of the battery 11. An electrical connector 200 of the battery 11 is mounted on the bracket 120, and the bracket 120 is slidably connected to the base 110, enabling rapid installation of the electrical connector 200. The slidable connection of the bracket 120 to the base 110 reduces the operating space required for fixing the electrical connector 200 in the mounting device 100, allowing for installation of the electrical connector 200 within a limited space. Furthermore, it reduces the space occupied by the mounting device 100 in the housing 1122 of the battery 11, improving the space utilization of the housing 1122, thereby increasing the energy density of the battery 11 and extending the service life of the electrical device.
