Technical Field

[0001] The present application relates to the field of battery technology, and in particular to battery devices and electrical equipment. Background Art

[0002] As the power and range requirements of new energy vehicles continue to increase, the feasibility and reliability of the routing of high-voltage connectors for power batteries are becoming increasingly demanding. However, in traditional routing arrangements, high-voltage connectors must avoid the sheet metal brackets in the battery, affecting the feasibility and fixation reliability of the overall routing. Summary of the Invention

[0003] Based on this, it is necessary to provide a battery device and electrical equipment to improve the feasibility of routing and fixation reliability of connectors.

[0004] In a first aspect, the present application provides a battery device, comprising: a bracket; a connector; a fixing structure, comprising a fixing seat and a first clamping member and a second clamping member connected to the fixing seat, the first clamping member and the second clamping member being spaced apart along a first direction, a portion of the bracket and a portion of the connector being located between the first clamping member and the second clamping member, and at least one of the first clamping member and the second clamping member being movable relative to the fixing seat so that the distance between the first clamping member and the second clamping member along the first direction is adjustable.

[0005] In the aforementioned battery device, when routing the wiring, the first and second clamps are positioned on opposite sides of the bracket, and the connector is placed between the first and second clamps. Because the position of at least one of the first and second clamps can be adjusted toward or away from each other, adjusting at least one of the first and second clamps allows the connector to be clamped to the bracket. This design utilizes the bracket as a fixed interface for routing the connector, reducing the spatial redundancy caused by the connector needing to avoid the bracket, minimizing the bracket's impact on routing, and improving the feasibility and reliability of the connector's routing.

[0006] In some embodiments, one of the fixing base and the first clamping member has an adjustment channel, and the other has a sliding portion that engages with the adjustment channel. The sliding portion can move along the adjustment channel to adjust the distance between the first clamping member and the second clamping member along the first direction. This design, with the introduction of the adjustment channel and the sliding portion, allows for smoother movement of the first clamping member and the second clamping member toward or away from each other, thereby achieving an effective and stable clamping action.

[0007] In some embodiments, the direction in which the adjustment channel extends is angled with the first direction, such that when the first clamping member moves along the adjustment channel, the first clamping member changes position along the first direction and perpendicular to the first direction. This design, with the direction in which the adjustment channel extends being angled with the first direction, facilitates the sliding portion driving the first clamping member to tilt closer to or away from the second clamping member.

[0008] In some embodiments, the fixing base includes a fixed portion and a connecting portion connected to each other, the second clamping member is connected to the connecting portion, and the fixed portion and the second clamping member are spaced apart along a first direction, and the fixed portion and the second clamping member are located on the same side of the connecting portion along a second direction, the second direction being perpendicular to the first direction; the adjustment channel is formed in the fixed portion, and the first clamping member includes a sliding portion for slidingly connecting to the fixed portion. This design allows the first clamping member disposed on the fixed portion to easily form a clamping space with the second clamping member in the first direction, thereby facilitating stable clamping of the connector and the bracket between the first clamping member and the second clamping member.

[0009] In some embodiments, the fixing portion includes a first sub-portion, a second sub-portion, and a connecting sub-portion; the first sub-portion is connected to the connecting portion; one end of the connecting sub-portion along the second direction is connected to the connecting portion, and the other end is connected to the second sub-portion, such that the second sub-portion and the first sub-portion are spaced apart along the second direction; the first sub-portion has a first surface, and the second sub-portion has a second surface, both of which extend along the extension direction of the adjustment channel, and the first and second surfaces are spaced apart to form the adjustment channel, and the sliding portion is slidably sandwiched between the first and second surfaces. This design, with the introduction of the first and second surfaces, facilitates the formation of the adjustment channel between the first and second sub-portions, allowing the sliding portion to better slide and fit within the adjustment channel, thereby facilitating rapid installation of the fixing structure.

[0010] In some embodiments, two first sub-sections are provided, spaced apart along a third direction perpendicular to the first and second directions. Each of the first sub-sections has a first surface, and the orthographic projection of the second sub-section onto the first surface covers at least a portion of each first surface, such that the second surface and the two first surfaces together form an adjustment channel. This design increases the space for the adjustment channel, facilitating the engagement of the sliding portion with the adjustment channel while also allowing for a greater number of sliding portions to engage, thereby improving the stability of the adjustment operation of the first clamping member.

[0011] In some embodiments, the first clamping member further includes an abutting portion; two sliding portions are provided, both of which are connected to the abutting portion and spaced apart along a third direction. Both sliding portions extend along the extension direction of the adjustment channel, and each sliding portion is sandwiched between a first surface and a second surface; the abutting portion and the second clamping member are spaced apart along the first direction, and are used to clamp the bracket and the connecting member together with the second clamping member. This design, in which the two sliding portions are sandwiched between the first surface and the second surface, not only strengthens the connection between the first clamping member and the fixed portion, but also makes the movement and adjustment of the first clamping member smoother.

[0012] In some embodiments, the first clamping member further includes a supporting portion and a limiting portion, the supporting portion and the limiting portion being respectively connected to both ends of the sliding portion along the extension direction of the adjustment channel, and both the supporting portion and the limiting portion being located on the side of the sliding portion facing the second clamping member along the first direction; the supporting portion, the limiting portion, and the sliding portion together form a receiving cavity, the first sub-portion and the connecting portion being accommodated in the receiving cavity, the supporting portion being used to abut against the connecting portion, and the limiting portion being used to abut against the first sub-portion. In such a design, the introduction of the supporting portion and the limiting portion limits the sliding travel of the sliding portion, reducing the risk of structural instability caused by slippage; at the same time, the introduction of the receiving cavity allows the first clamping member to be sleeved outside the fixing portion, thereby making the combination between the two tighter.

[0013] In some embodiments, the width of the connecting sub-part along the third direction is smaller than the distance between the two sliding parts along the third direction. This design facilitates the rapid installation of the first clamping member on the fixing seat and improves the assembly efficiency of the fixing structure.

[0014] In some embodiments, a sliding groove is formed on a surface of the fixing portion facing the second clamping member along the first direction. The sliding groove serves as an adjustment channel, and the sliding portion is slidably connected to the sliding groove. The first clamping member includes an abutting portion connected to the sliding portion. The abutting portion and the second clamping member are spaced apart along the first direction to jointly clamp the bracket and the connecting member with the second clamping member. This design allows the abutting portion and the second clamping member to be positioned relative to each other, making it easier to clamp the connecting member and the bracket together with the second clamping member.

[0015] In some embodiments, the first clamping member further includes two mounting portions, each connected to a sliding portion, the two mounting portions being spaced apart along the third direction, and the second sub-portion being slidably disposed between the two mounting portions. This design improves the stability of the first clamping member during sliding relative to the fixed base and also reduces the risk of the connector or bracket being dislodged due to external forces causing the first and second clamping members to deviate along the third direction.

[0016] In some embodiments, the acute angle formed between the extension direction of the adjustment channel and the first direction is α, the static friction coefficient between the adjustment channel and the sliding portion is μ, and tan90°-α≤μ. This design sets the static friction coefficient μ to be greater than or equal to tan(90°-α), preventing the sliding portion from overcoming static friction on its own, effectively achieving a self-locking function and improving the reliability of the cable fixation.

[0017] In some embodiments, the battery device further includes a locking member for locking the sliding portion in the adjustment channel. With this design, effective locking is achieved through the locking member, thereby improving the reliability of the wiring fixation.

[0018] In some embodiments, the sliding portion and the adjustment channel have an interference fit, so that there is a certain friction between the sliding portion and the inner wall of the adjustment channel, so that the first clamping member and the second clamping member can effectively clamp the connector and the bracket, thereby improving the fixing reliability of the wiring.

[0019] In some embodiments, the battery device further includes a restraining assembly disposed on the mounting base, including at least two connectors, some of which are clamped between the first clamping member and the second clamping member, while some of which are fixed to the restraining assembly. This design, by introducing the restraining assembly to restrain some of the connectors, reduces the number of connectors required to be fixed between the first clamping member and the second clamping member, thereby reducing the overall size of the mounting structure.

[0020] In a second aspect, the present application provides an electrical device, which includes any one of the above battery devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0039] As the power and range requirements of new energy vehicles continue to increase, the feasibility and reliability of routing high-voltage connectors for power batteries are becoming increasingly demanding. The battery housing contains sheet metal brackets, so when routing the cables, the high-voltage connectors must be routed away from the brackets to reduce the risk of the brackets cutting the connectors.

[0040] However, to avoid the sheet metal brackets, additional space must be created within the available space of the box, making routing of high-voltage connectors difficult and reducing the feasibility of routing. Furthermore, avoiding the sheet metal brackets leaves less room for fixing them, reducing the reliability of the routing.

[0041] Based on this, in order to address the problem of reduced routing feasibility and fixing reliability in traditional battery devices, the present application provides a battery device, in which the first clamp and the second clamp are distributed on opposite sides of the bracket during routing, and the connector is placed between the first clamp and the second clamp. Since the position of at least one of the first clamp and the second clamp can be adjusted in the direction of moving closer to or away from each other, at least one of the first clamp and the second clamp is adjusted so that the connector is clamped on the bracket. With such a design, the bracket is used as a fixing interface for routing the connector, reducing the space redundancy design caused by the connector needing to avoid the bracket, reducing the influence of the bracket on routing, and improving the routing feasibility and fixing reliability of the connector.

[0042] The battery cells disclosed in the embodiments of the present application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. A power supply system comprising the battery cells and battery devices disclosed in the present application can be used to form the electrical device.

[0043] The present invention provides an electrical device that uses a battery device as a power source. The electrical device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0044] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0045] Please refer to Figure 1 , Figure 1A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery device 100 is provided inside the vehicle 1000. The battery device 100 may be provided at the bottom, head or tail of the vehicle 1000. The battery device 100 may be used to power the vehicle 1000. For example, the battery device 100 may serve as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to power the motor 300, for example, for starting, navigating and operating power requirements of the vehicle 1000 during driving.

[0046] In some embodiments of the present application, the battery device 100 can serve not only as an operating power source for the vehicle 1000 , but also as a driving power source for the vehicle 1000 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000 .

[0047] Please refer to Figure 2 , Figure 2 This is an exploded view of a battery device 100 provided in some embodiments of the present application. The battery device 100 includes a housing 10 and a battery cell 20, with the battery cell 20 housed within the housing 10. The housing 10 is used to provide a storage space for the battery cell 20 and can have various structures. In some embodiments, the housing 10 can include a first portion 11 and a second portion 12, which overlap each other and together define a storage space for the battery cell 20. The second portion 12 can be a hollow structure with one end open. The first portion 11 can be a plate-like structure, with the first portion 11 overlapping the open side of the second portion 12, so that the first portion 11 and the second portion 12 together define a storage space. The first portion 11 and the second portion 12 can also be hollow structures with one end open, with the open side of the first portion 11 overlapping the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0048] In the battery device 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections among the multiple battery cells 20. The multiple battery cells 20 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery device 20 may be housed within the housing 10. Of course, the battery device 100 may also be a battery module formed by first connecting multiple battery cells 20 in series, in parallel, or in a hybrid connection, and then the multiple battery device 100 modules are further connected in series, in parallel, or in a hybrid connection to form an entire battery device 100, which is then housed within the housing 10. The battery device 100 may also include other structures, for example, the battery device 100 may further include a busbar component for electrically connecting the multiple battery cells 20.

[0049] Each battery cell 20 may be a secondary battery or a primary battery, and may also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0050] According to some embodiments of this application, please refer to Figures 3 to 5 The present application provides a battery device 100, which includes: a bracket 30, a connector 40, and a fixing structure 50. The fixing structure 50 includes a fixing seat 51 and a first clamping member 52 and a second clamping member 53 connected to the fixing seat 51. The first clamping member 52 and the second clamping member 53 are spaced apart along a first direction X. Parts of the bracket 30 and the connector 40 are both located between the first clamping member 52 and the second clamping member 53. At least one of the first clamping member 52 and the second clamping member 53 can move relative to the fixing seat 51, so that the distance between the first clamping member 52 and the second clamping member 53 along the first direction X can be adjusted, thereby enabling the first clamping member 52 and the second clamping member 53 to clamp the connector 40 and the bracket 30.

[0051] The connector 40 may be a component within the battery device 100 used to transmit electrical energy or collect signals. It may be electrically connected to the battery cells 20 within the housing 10 or to other components within the housing 10. The connector 40 typically includes a conductor and insulating protective material, such as heat shrink tubing or an insulating mesh tube, surrounding the conductor. For example, the connector 40 may be a high-voltage copper busbar, a high-voltage aluminum busbar, or a sampling wire harness.

[0052] The bracket 30 can refer to a structure within the housing 10 used to secure components, such as a sheet metal structure used to secure a control box or other components. The bracket 30 can also be a beam structure within the housing 10. Because the edges of the bracket 30 are typically sharp, in conventional battery devices 100, the connector 40 typically avoids the bracket 30, requiring additional clearance within the housing 10. This makes the distribution of the connector 40 more difficult within the limited space of the housing 10, reducing the feasibility of its routing. Furthermore, routing within this limited space makes it impossible to effectively secure the connector 40, affecting the reliability of the routing.

[0053] To this end, this embodiment introduces a fixing structure 50, which clamps the connector 40 to the bracket 30. This utilizes the bracket 30 as a fixing interface for the connector 40, ensuring a stable fixation of the connector 40 to the bracket 30 and reducing the risk of injuries caused by relative movement between the connector 40 and the bracket 30. This also reduces the space redundancy caused by the connector 40 needing to avoid the bracket 30, facilitating the fixing of the connector 40 and improving the reliability of the wiring.

[0054] In the fixing structure 50, the fixing base 51 refers to a structure that provides support for the installation of the first clamping member 52 and the second clamping member 53. It can be designed as a plate-shaped structure or an inverted L-shaped structure. One of the first clamping member 52 and the second clamping member 53 can be designed as an adjustable structure, or both can be designed as adjustable structures. For example, when the first clamping member 52 and the second clamping member 53 are both designed as adjustable structures, the first clamping member 52 and the second clamping member 53 can be moved so that the first clamping member 52 and the second clamping member 53 clamp the bracket 30 and the connecting member 40.

[0055] There are many ways to adjust the first clamping member 52 or the second clamping member 53 on the fixed seat 51, for example: the first clamping member 52 or the second clamping member 53 is adjusted in position through a screw slider mechanism; or the first clamping member 52 or the second clamping member 53 is adjusted on the fixed seat 51 through a slider and a slide groove matching structure, and after adjustment, it can be fixed by a pin or a clamping method.

[0056] In addition, to improve the protection of the connecting member 40, an elastic structure such as foam, rubber, etc. can be provided between the first clamping member 52 or the second clamping member 53 and the connecting member 40, and between the bracket 30 and the connecting member 40.

[0057] With this design, the bracket 30 is used as a fixed interface for the routing of the connector 40, reducing the space redundancy design caused by the connector 40 needing to avoid the bracket 30, reducing the impact of the bracket 30 on the routing, and improving the routing feasibility and fixing reliability of the connector 40.

[0058] According to some embodiments of the present application, optionally, please refer to Figure 6 One of the fixing seat 51 and the first clamping member 52 has an adjustment channel 54, and the other has a sliding portion 55 that cooperates with the adjustment channel 54. The sliding portion 55 can move along the adjustment channel 54 so that the distance between the first clamping member 52 and the second clamping member 53 along the first direction X can be adjusted.

[0059] The adjustment channel 54 refers to a channel structure on the fixed seat 51 or the first clamping member 52 through which the sliding portion 55 can move. When the sliding portion 55 is controlled to move in the adjustment channel 54, the first clamping member 52 moves on the fixed seat 51 toward the side of the second clamping member 53, so that the first clamping member 52 and the second clamping member 53 clamp the connecting member 40 and the bracket 30. The adjustment channel 54 can be designed to be inclined relative to the second clamping member 53, so that when the sliding portion 55 is controlled to move in the adjustment channel 54, the first clamping member 52 can move closer to or farther from the second clamping member 53 to achieve clamping or releasing. Alternatively, the adjustment channel 54 can be parallel or approximately parallel to the surface of the second clamping member 53, but the depth of the adjustment channel 54 gradually changes along its own extension direction L, so that when the sliding portion 55 moves in the adjustment channel 54, it will gradually move closer to or farther from the second clamping member 53.

[0060] Here, "controlled" means that the sliding portion 55 needs to be driven by an external force to move in the adjustment channel 54. This means that after the sliding portion 55 is controlled to move between the first clamping member 52 and the second clamping member 53 to clamp the connecting member 40, the sliding portion 55 can remain stationary in the adjustment channel 54 when not subject to external forces, so that the first clamping member 52 and the second clamping member 53 clamp the connecting member 40. For example, friction between the sliding portion 55 and the adjustment channel 54 can maintain the clamping state between the first clamping member 52 and the second clamping member 53; or, between the sliding portion 55 and the adjustment channel 54, one of the protrusions is provided and the other is provided with a plurality of recesses, and the protrusions are stuck in different recesses as the sliding portion 55 moves, so that the first clamping member 52 and the second clamping member 53 maintain the clamping state; or, a pin structure is introduced, and when the sliding portion 55 moves to the desired position, the sliding portion 55 is locked by a locking structure.

[0061] Furthermore, the adjustment channel 54 can be positioned in various locations on the fixed base 51. For example, the adjustment channel 54 can be located on a surface of the fixed base 51 facing the second clamping member 53, or on a circumferential side surface of the fixed base 51. Furthermore, the number of adjustment channels 54 can be one or more. If there are multiple adjustment channels 54, the adjustment channels 54 can be arranged side by side and spaced apart on the fixed base 51, with the sliding portions 55 fitting one-to-one within the adjustment channels 54.

[0062] Such a design introduces the adjustment channel 54 and the sliding portion 55 , so that the first clamping member 52 and the second clamping member 53 move toward or away from each other more smoothly, thereby achieving an effective and stable clamping action.

[0063] According to some embodiments of the present application, optionally, please refer to Figure 6 and Figure 7 The extension direction L of the adjustment channel 54 forms an angle with the first direction X, so that when the first clamping member 52 moves along the adjustment channel 54, the first clamping member 52 produces a position change along the first direction X and perpendicular to the first direction X.

[0064] When the angle between the extension direction L of the adjustment channel 54 and the first direction X is less than 90°, it means that the adjustment channel 54 is inclined. In this way, when the sliding portion 55 moves along the adjustment channel 54, it will drive the first clamping member 52 to tilt closer to or away from the second clamping member 53, so as to clamp or release the connecting member 40 and the bracket 30. When the angle between the extension direction L of the adjustment channel 54 and the first direction X is equal to 90°, it means that the extension direction L of the adjustment channel 54 is or is approximately horizontal. At this time, in order to achieve the sliding portion 55 driving the first clamping member 52 to tilt closer to or away from the second clamping member 53, the depth of the adjustment channel 54 can be gradually deepened or shallowed along its own extension direction L. For specific examples, please refer to Figure 5 The adjusting channel 54 includes a first end 541 and a second end 542 along its own extension direction L. The adjusting channel 54 is inclined relative to the second clamping member 53, and the first end 541 is closer to the second clamping member 53 than the second end 542.

[0065] As can be seen, when the sliding portion 55 moves toward the first end 541, the sliding portion 55 moves closer to the second clamping member 53, so that the first clamping member 52 and the second clamping member 53 can clamp the bracket 30 and the connecting member 40. When the sliding portion 55 moves toward the second end 542, the sliding portion 55 moves further away from the second clamping member 53, so that the first clamping member 52 and the second clamping member 53 can loosen the bracket 30 and the connecting member 40.

[0066] At the same time, the extension direction L of the adjustment channel 54 determines the movement direction of the sliding portion 55, and this extension direction L can be designed in various ways. For ease of understanding, taking the second clamping member 53 as a quadrilateral structure as an example, the extension direction L of the adjustment channel 54 can maintain the same extension trend as the length direction of the second clamping member 53, but intersect with the length direction; alternatively, the extension direction L of the adjustment channel 54 can maintain the same extension trend as the width direction of the second clamping member 53, but intersect with the width direction; or alternatively, the extension direction L of the adjustment channel 54 can maintain the same extension trend as the diagonal direction of the second clamping member 53. By tilting the adjustment channel 54 relative to the second clamping member 53 in this manner, the sliding portion 55 can effectively achieve the tightening or loosening action between the first clamping member 52 and the second clamping member 53 when moving between the first end 541 and the second end 542.

[0067] With this design, the extending direction L of the adjustment channel 54 forms an angle with the first direction X, so that the sliding portion 55 can drive the first clamping member 52 to tilt closer to or away from the second clamping member 53 .

[0068] According to some embodiments of the present application, optionally, please refer to Figure 6 The fixing seat 51 includes a fixing portion 512 and a connecting portion 511 connected to each other, the second clamping member 53 is connected to the connecting portion 511, and the fixing portion 512 and the second clamping member 53 are spaced apart along the first direction X, the fixing portion 512 and the second clamping member 53 are located on the same side of the connecting portion 511 along the second direction Y, and the second direction Y is perpendicular to the first direction X; the adjustment channel 54 is formed in the fixing portion 512, and the first clamping member 52 includes a sliding portion 55 to slideably connect the fixing portion 512.

[0069] The fixing portion 512 and the second clamping member 53 are located on the same side of the connecting portion 511. This allows the first clamping member 52 disposed on the fixing portion 512 to easily form a clamping space with the second clamping member 53 in the first direction X. Furthermore, the position of the adjustment channel 54 on the fixing portion 512 can be designed in a variety of ways. For example, the adjustment channel 54 can be disposed on the side of the fixing portion 512 facing the second clamping member 53; or on the side of the fixing portion 512 along the second direction Y; or, of course, on the side of the fixing portion 512 along the third direction Z, where the third direction Z, the second direction Y, and the first direction X are perpendicular to each other.

[0070] There can be one or more adjustment channels 54 on the fixing portion 512. When there are more than one adjustment channels 54, there can also be more than one sliding portion 55, which are arranged one-to-one with the adjustment channels 54.

[0071] Such a design makes it easy for the first clamping member 52 provided on the fixing portion 512 to form a clamping space with the second clamping member 53 in the first direction X, thereby facilitating stable clamping of the connecting member 40 and the bracket 30 between the first clamping member 52 and the second clamping member 53 .

[0072] According to some embodiments of the present application, optionally, please refer to Figure 6 The fixing portion 512 includes a first sub-portion 51a, a second sub-portion 51b and a connecting sub-portion 51c; the first sub-portion 51a is connected to the connecting portion 511; one end of the connecting sub-portion 51c along the second direction Y is connected to the connecting portion 511, and the other end is connected to the second sub-portion 51b, so that the second sub-portion 51b and the first sub-portion 51a are spaced apart along the second direction Y; the first sub-portion 51a has a first surface 51d, and the second sub-portion 51b has a second surface 51e. The first surface 51d and the second surface 51e both extend along the extension direction L of the adjustment channel 54. The first surface 51d and the second surface 51e are spaced apart to form the adjustment channel 54, and the sliding portion 55 is slidably clamped between the first surface 51d and the second surface 51e.

[0073] As can be seen, an adjustment channel 54 is formed between the first surface 51d and the second surface 51e. The sliding portion 55, which engages with the adjustment channel 54, is equivalent to being sandwiched between the first surface 51d and the second surface 51e. The first surface 51d and the second surface 51e can both be flat or curved. Of course, to achieve a better angle between the formed adjustment channel 54 and the first direction X, the first surface 51d and the second surface 51e can both be arranged at an angle to the first direction X. For example, the first surface 51d and the second surface 51e are arranged parallel to each other and both form an angle with the first direction X.

[0074] The connection between the connecting sub-section 51c and the connecting portion 511 and the second sub-section 51b can be achieved through various methods, including but not limited to bolting, clamping, welding, and bonding. Alternatively, the connecting sub-section 51c, the connecting portion 511, and the second sub-section 51b can be designed as an integrated structure. Furthermore, the connection between the first sub-section 51a and the connecting portion 511 can be achieved through, but not limited to, bolting, clamping, welding, and bonding. Alternatively, the first sub-section 51a and the connecting portion 511 can be designed as an integrated structure.

[0075] Such a design introduces the first surface 51d and the second surface 51e, so as to form an adjustment channel 54 between the first sub-portion 51a and the second sub-portion 51b, so that the sliding portion 55 can better slide and fit in the adjustment channel 54, which is beneficial for the rapid installation of the fixing structure 50.

[0076] According to some embodiments of the present application, optionally, two first sub-sections 51a are provided, and the two first sub-sections 51a are spaced apart along the third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y; the two first sub-sections 51a each have a first surface 51d, and the positive projection of the second sub-section 51b onto the first surface 51d covers at least part of each first surface 51d, so that the second surface 51e and the two first surfaces 51d together form an adjustment channel 54.

[0077] It can be seen that the orthographic projection of the second surface 51e of the second sub-portion 51b onto the first surface 51d also covers at least a portion of each first surface 51d, thereby forming an adjustment channel 54 between the second surface 51e and the two first surfaces 51d. In this case, the formed adjustment channel 54 can be a continuous through-structure along the third direction Z, or it can be divided by the connecting sub-portion 51c in the third direction Z to form two channel segments, etc.

[0078] At the same time, the formed adjustment channel 54 can be cooperated with one or two sliding parts 55 to drive the first clamping member 52 to move closer to or away from one side of the second clamping member 53.

[0079] Such a design can increase the space of the adjustment channel 54 , which not only facilitates the cooperation between the sliding portion 55 and the adjustment channel 54 , but also allows a greater number of sliding portions 55 to cooperate, thereby improving the stability of the adjustment operation of the first clamping member 52 .

[0080] According to some embodiments of the present application, optionally, please refer to Figure 6 The first clamping member 52 also includes a contact portion 521; two sliding portions 55 are provided, the two sliding portions 55 are both connected to the contact portion 521, and the two sliding portions 55 are spaced apart along the third direction Z, the two sliding portions 55 extend along the extension direction L of the adjustment channel 54, and the two sliding portions 55 are each clamped between a first surface 51d and a second surface 51e; the contact portion 521 and the second clamping member 53 are spaced apart along the first direction X, so as to clamp the bracket 30 and the connecting member 40 together with the second clamping member 53.

[0081] It can be seen that the two sliding parts 55 are respectively clamped between the first surface 51d and the second surface 51e along the third direction Z. When the two sliding parts 55 move along the extension direction L of the adjustment channel 54, the two sliding parts 55 jointly drive the abutting part 521 to change its position along the first direction X and the second direction Y, so that the abutting part 521 and the second clamping part 53 can jointly clamp the connecting part 40 and the bracket 30.

[0082] With this design, the two sliding portions 55 are clamped between the first surface 51d and the second surface 51e, which not only makes the combination between the first clamping member 52 and the fixing portion 512 tighter, but also makes the movement and adjustment of the first clamping member 52 smoother.

[0083] According to some embodiments of the present application, optionally, please refer to Figure 6 The first clamping member 52 also includes a supporting portion 52b and a limiting portion 56, which are respectively connected to the two ends of the sliding portion 55 along the extension direction L of the adjustment channel 54, and the supporting portion 52b and the limiting portion 56 are both located on the side of the sliding portion 55 toward the second clamping member 53 along the first direction X; the supporting portion 52b, the limiting portion 56 and the sliding portion 55 jointly form an accommodating cavity, and the first sub-portion 51a and the connecting portion 511 are accommodated in the accommodating cavity, the supporting portion 52b is used to abut against the connecting portion 511, and the limiting portion 56 is used to abut against the first sub-portion 51a.

[0084] The accommodating cavity refers to the internal space of the first clamping member 52, which can accommodate a part of the fixing portion 512 inside the first clamping member 52, so that the first clamping member 52 can be inserted outside the fixing portion 512, thereby reducing the space occupied by the first clamping member 52 between the fixing portion 512 and the second clamping member 53, leaving more clamping space for the abutting portion 521 and the second clamping member 53.

[0085] At the same time, the gap between the two sliding portions 55 can communicate with the accommodating cavity. Thus, when the first clamping member 52 is inserted outside the fixed portion 512, the two sliding portions 55 can be clamped between the second surface 51e and the corresponding first surface 51d. At this time, when the two sliding portions 55 move along the extension direction L of the adjustment channel 54, the support portion 52b and the limit portion 56 can respectively abut and cooperate with the ends of the fixed portion 512 along the second direction Y to limit the sliding travel of the sliding portions 55. This ensures a stable connection between the first clamping member 52 and the fixed portion 512, reducing the risk of the structure slipping due to over-adjustment.

[0086] There are various ways to connect the support portion 52b, the limiting portion 56 and the sliding portion 55. The support portion 52b, the limiting portion 56 and the sliding portion 55 can also be designed as an integrated structure.

[0087] Such a design introduces the support portion 52b and the limit portion 56 to limit the sliding stroke of the sliding portion 55, thereby reducing the risk of slipping and causing structural instability; at the same time, the accommodating cavity is introduced so that the first clamping member 52 is sleeved outside the fixing portion 512, thereby making the combination between the two tighter.

[0088] According to some embodiments of the present application, optionally, please refer to Figure 5, the width of the connecting sub-portion 51 c along the third direction Z is smaller than the distance between the two sliding portions 55 along the third direction Z.

[0089] When the first clamping member 52 is inserted through the accommodating cavity and positioned outside the connecting portion 511 and the first sub-portion 51a, the distance between the two sliding portions 55 is greater than that between the connecting sub-portion 51c. Therefore, the connecting sub-portion 51c can pass through the space between the two sliding portions 55, so that the two sliding portions 55 are located on either side of the connecting sub-portion 51c along the third direction Z. At this time, the first clamping member 52 is pushed along the extension direction L of the adjustment channel 54, so that each sliding portion 55 is clamped between the second surface 51e and the corresponding first surface 51d, thereby quickly completing the installation between the first clamping member 52 and the fixing base 51.

[0090] Such a design facilitates quick installation of the first clamping member 52 on the fixing seat 51 , thereby improving the assembly efficiency of the fixing structure 50 .

[0091] According to some embodiments of the present application, optionally, please refer to Figure 8 and Figure 9 A sliding groove is formed on the surface of the fixing portion 512 toward the second clamping member 53 along the first direction X, the sliding groove serves as an adjustment channel 54, and the sliding portion 55 is slidably connected to the sliding groove; the first clamping member 52 includes an abutting portion 521, the abutting portion 521 is connected to the sliding portion 55, and the abutting portion 521 is spaced apart from the second clamping member 53 along the first direction X, so as to be used to clamp the bracket 30 and the connecting member 40 together with the second clamping member 53.

[0092] The sliding groove is an inward depression formed on the surface of the fixing portion 512 facing the second clamping member 53, forming a groove-like structure. The sliding groove can be distributed in various ways on the surface of the fixing portion 512 facing the second clamping member 53. For example, the sliding groove can extend along the surface of the fixing portion 512 in a direction parallel to the surface of the connecting portion 511 and intersecting the first direction X; or the sliding groove can extend in a direction perpendicular to the surface of the connecting portion 511 and intersecting the first direction X.

[0093] At the same time, one end of the slide groove may extend to the edge of the fixing portion 512, or may not extend to the edge of the fixing portion 512. In some examples, the two ends of the slide groove extend to opposite ends of the fixing portion 512, respectively. In this case, the sliding portion 55 can be inserted from one end of the slide groove, allowing the first clamping member 52 to be quickly installed on the fixing portion 512.

[0094] The first clamping member 52 further includes a mounting portion 52a, which is connected to the abutment portion 521 via a support portion 52b. A sliding portion 55 is connected to the surface of the mounting portion 52a facing away from the support portion 52b. To enhance the structural strength of the first clamping member 52, a plurality of reinforcing ribs 52c may be provided between the mounting portion 52a and the abutment portion 521.

[0095] Such a design allows the abutting portion 521 to be better positioned relative to the second clamping member 53 , making it easier for the abutting portion 521 and the second clamping member 53 to clamp the connecting member 40 and the bracket 30 .

[0096] According to some embodiments of the present application, optionally, the first clamping member 52 further includes two mounting portions 52a, each of the two mounting portions 52a is connected to a sliding portion 55, the two mounting portions 52a are spaced apart along the third direction Z, and the second sub-portion 51b is slidably clamped between the two mounting portions 52a.

[0097] As can be seen, the second sub-portion 51b, clamped between the two mounting portions 52a, serves as a guide, further stabilizing the sliding movement of the first clamping member 52. Furthermore, if the first clamping member 52 or the second clamping member 53 is subjected to an external force in the third direction Z, the second sub-portion 51b can abut against the mounting portion 52a, reducing the displacement of the first clamping member 52 or the second clamping member 53 in the third direction Z, thereby reducing the risk of the connector 40 or the bracket 30 being dislodged from the fixed structure 50.

[0098] The connection between the mounting portion 52a and the sliding portion 55 may be, but is not limited to, bolt connection, clamping, riveting, welding, etc. Of course, the mounting portion 52a and the sliding portion 55 may also be designed as an integrated structure.

[0099] Such a design improves the stability of the sliding process of the first clamping member 52 relative to the fixing seat 51; at the same time, it can also reduce the risk of the first clamping member 52 and the second clamping member 53 being offset along the third direction Z due to external force, causing the connecting member 40 or the bracket 30 to fall out.

[0100] According to some embodiments of this application, please refer to Figure 7 Optionally, the acute angle formed by the extension direction L of the adjustment channel 54 and the first direction X is α, the static friction coefficient between the adjustment channel 54 and the sliding portion 55 is μ, and tan90°-α≤μ.

[0101] It can be seen that when the adjustment channel 54 forms an acute angle α with the first direction X, the static friction force experienced by the sliding portion 55 is: mgμcos(90°-α), and the force experienced along the extension direction L of the adjustment channel 54 is: mgsin(90°-α), where m is the mass of the sliding portion 55 and g is the acceleration due to gravity. If mgμcos(90°-α) < mgsin(90°-α), that is, μ < tan(90°-α), the sliding portion 55 can overcome its own static friction and move along the adjustment channel 54 on its own, failing to achieve a self-locking effect.

[0102] To this end, in this embodiment, the coefficient of static friction is set to μ greater than or equal to tan(90° - α), preventing the sliding portion 55 from overcoming static friction on its own, thereby achieving an effective self-locking function. Of course, to enhance the self-locking effect, the size of the sliding portion 55 can be slightly larger than the size of the adjustment channel 54, allowing the sliding portion 55 to be in a stretched state within the adjustment channel 54.

[0103] With this design, the static friction coefficient μ is greater than or equal to tan (90°-α), so that the sliding portion 55 cannot overcome the static friction by itself, thus achieving an effective self-locking function and improving the fixing reliability of the wiring.

[0104] According to some embodiments of the present application, optionally, the battery device 100 further includes a locking member, which is used to lock the sliding portion 55 in the adjustment channel 54 .

[0105] Among them, the structure of the locking member can have various designs, for example: the locking member can be but not limited to a bolt, a pin, etc., or it can be a snap-fit ​​structure. When the sliding part 55 moves to a certain position of the adjustment channel 54, the snap-fit ​​structure is snapped into the corresponding concave structure in the adjustment channel 54.

[0106] With this design, effective locking is achieved through the locking piece, thereby improving the fixation reliability of the wiring.

[0107] According to some embodiments of the present application, optionally, the sliding portion 55 is interference fit with the adjustment channel 54 .

[0108] An interference fit should be understood as follows: the size of the sliding portion 55 is larger than the size of the adjustment channel 54, so that there is a certain friction between the sliding portion 55 and the inner wall of the adjustment channel 54. When the sliding portion 55 moves to the desired clamping position, the first clamping member 52 and the second clamping member 53 can clamp the connector 40 and the bracket 30 under the action of the friction force.

[0109] Such a design creates a certain friction between the sliding portion 55 and the inner wall of the adjustment channel 54 , so that the first clamping member 52 and the second clamping member 53 can effectively clamp the connector 40 and the bracket 30 , thereby improving the reliability of the wiring fixation.

[0110] According to some embodiments of the present application, optionally, the battery device 100 also includes a constraint assembly 60 provided on the fixing seat 51, the number of connecting members 40 is at least two, a part of the connecting members 40 are clamped between the first clamping member 52 and the second clamping member 53, and a part of the connecting members 40 are fixed to the constraint assembly 60.

[0111] When the number of connectors 40 between the first clamping member 52 and the second clamping member 53 increases, the space between the first clamping member 52 and the second clamping member 53 increases, which increases the space occupied within the housing 10 of the battery device 100. To this end, the restraining assembly 60 is introduced to fix some of the connectors 40, thereby reducing the number of connectors 40 required to be fixed between the first clamping member 52 and the second clamping member 53. In this case, some of the connectors 40 can be distributed sequentially along the height direction of the fixing structure 50.

[0112] The restraint assembly 60 is a structure that can restrain the connector 40 , and the restraint method can be binding, clamping, etc. At the same time, the connection method of the restraint assembly 60 on the fixing seat 51 can be but not limited to sleeve connection, clamping, bolt connection, etc.

[0113] For some examples, see Figure 6 The restraint assembly 60 includes a mounting member 62 and a restraint member 61 connected to the mounting member 62 . The mounting member 62 is detachably connected to the fixing seat 51 . The restraint member 61 is used to bind part of the connecting member 40 .

[0114] The mounting member 62 is a component that mounts the restraint assembly 60 on the fixing base 51 and can be designed in a circular or square configuration. The restraint member 61 is a component that secures the connector 40 by binding. It can be, but is not limited to, a cable tie, thereby securing the connector 40 to at least one of the first clamping member 52, the second clamping member 53, and the fixing base 51. The mounting member 62 can be connected to the fixing base 51 by, but is not limited to, a snap-on connection, a sleeve connection, or a bolt connection. The number of restraint members 61 can be one or more.

[0115] With this design, the constraint assembly 60 is introduced to constrain some of the connecting members 40 , thereby reducing the number of connecting members 40 that need to be fixed between the first clamping member 52 and the second clamping member 53 , which is beneficial to reducing the overall size of the fixing structure 50 .

[0116] According to some embodiments of the present application, the present application provides an electric device, which includes the battery device 100 according to any one of the above items.

[0117] According to some embodiments of this application, please refer to Figures 3 to 9The present application provides a battery device 100, which includes a housing 10, a connector 40, a bracket 30, a fixing structure 50, and a constraint assembly 60. The fixing structure 50 includes a fixing seat 51 and a first clamping member 52 and a second clamping member 53 provided on the fixing seat 51. The fixing seat 51 is provided with an inclined adjustment channel 54, and the first clamping member 52 is provided with a sliding portion 55. The sliding portion 55 is engaged in the adjustment channel 54. By moving the sliding portion 55, the first clamping member 52 and the second clamping member 53 are brought together, so that the connector 40 is clamped on the bracket 30. The constraint assembly 60 is provided on the fixing seat 51 and is used to constrain part of the connector 40.

[0118] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0119] The above embodiments merely illustrate several implementation methods of the present application.
