DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] Figure 1 This is a schematic diagram of an assembly of an electrical box assembly provided by an embodiment of the utility model. Figure 2 Schematic diagram of an exploded structure of an electrical box assembly provided by an embodiment of the utility model, such as Figure 1 and Figure 2 As shown, the battery pack includes:

[0038] A box body and an electrical box assembly arranged inside the box body.

[0039] The electrical component 1 and the connecting assembly 2 , the connecting assembly 2 includes a bracket 21 and an electrical installation component 22 , and the electrical installation component 22 includes at least a movable connecting component 221 and a fixed connecting component 222 .

[0040] One end of the fixed connecting member 222 in the first direction Z is fixed to the bracket 21, and the other end of the fixed connecting member 222 in the first direction Z is detachably connected to the electrical component 1. The first end 2212 of the movable connecting member 221 is movably connected to the bracket 21, and the second end 2213 of the movable connecting member 221 is detachably connected to the electrical component 1, so that the distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X is adjustable.

[0041] The first end 2212 and the second end 2213 are two ends of the movable connecting member 221 in the first direction Z, the second direction X and the first direction Z are two intersecting directions, and the first direction Z intersects with the plane where the bracket 21 is located.

[0042] It can be seen from the above embodiments that in the embodiment of the utility model, since the fixed connecting member 222 is fixed to the bracket 21 at one end in the first direction Z, the other end of the fixed connecting member 222 in the first direction Z is detachably connected to the electrical component 1, the first end 2212 of the movable connecting member 221 is movably connected to the bracket 21, and the second end 2213 of the movable connecting member 221 is detachably connected to the electrical component 1, so that the distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X is adjustable. Therefore, when the specification of the electrical component 1 changes, resulting in a change in the connection position of the electrical component 1 and the bracket 21, the distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X can be adjusted, so that the bracket 21 can adapt to different types of electrical components 1. In this way, even if the specification of the electrical component 1 changes, there is no need to change the bracket 21, so that the bracket 21 can install a variety of electrical components 1 of different specifications, thereby saving the cost of redesigning and making molds for the bracket 21, and improving the production efficiency of the battery pack.

[0043] Among them, the box body is a shell structure for accommodating the battery pack. In some embodiments, the box body may include an upper cover, a lower box body, a sealing structure, etc. The material selection and structural form of the box body mainly depend on the size of the battery pack, the structural form (regular or special-shaped structure), mechanical strength and lightweight goals and other requirements. Exemplarily, the material of the box body can be a low-density lightweight material, such as aluminum alloy, composite material, etc., on the one hand, and it can be high-strength steel on the other hand. The embodiments of the utility model do not limit this.

[0044] The electrical component 1 can be any electrical component such as a fuse, a current sensor, a temperature sensor and a controller, and the embodiments of the present utility model do not limit this. Among them, the fuse is a current protection component that can automatically blow the circuit in the battery pack before the circuit is broken, protecting the circuit in the battery pack from overcurrent damage. Multiple fuses are usually installed in the battery pack to protect the circuit in the battery pack. The current sensor measures the use of electric energy and controls the circuit by detecting the current in the circuit. Current sensors are installed in the battery pack to ensure the safety performance of the battery pack. The temperature sensor monitors the status of the battery and controls related temperature management devices by measuring the temperature of the battery pack. The temperature sensor is usually installed inside the battery pack to monitor the temperature. The controller is used to monitor the status of the battery pack and control the charging and discharging process. The controller can also perform intelligent management of the battery pack to extend the life of the battery pack.

[0045] The bracket 21 connecting the electrical component 1 is usually a plate-like structure, a frame-like structure or other structures, which is not limited in this embodiment of the present invention. The bracket 21 includes at least one mounting surface for mounting a movable connector 221 and a fixed connector 222. Among them, the fixed connector 222 can be a connector such as a screw, a clamping rod, or a connecting rod with a threaded hole. The fixed connector 222 can be fixed to the mounting surface of the bracket 21 by welding, hinged, clamped, etc. The movable connector 221 can also be a connector such as a screw, a clamping rod, or a connecting rod with a threaded hole. The second end 2213 of the movable connector 221 can be connected by sliding connection, plug-in or other connection methods with replaceable connection points, which is not limited in this embodiment of the present invention.

[0046] In addition, it should be noted that, in the embodiment of the utility model, the X-axis direction and the Z-axis direction intersect, the X-axis direction and the Y-axis direction intersect, and the Y-axis direction and the Z-axis direction intersect. For the convenience of explanation, the first direction is defined as the Z-axis direction, the second direction is defined as the X-axis direction, and the third direction is defined as the Y-axis direction. It is further explained that the definition of vertical in the specification should be understood as vertical within a 90-degree fluctuation of 10%, that is, the angle between the first direction and the second direction defined as between 80 degrees and 90 degrees should be understood as vertical.

[0047] The adjustable distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X can be achieved by sliding connection, plugging or other connection methods with replaceable connection points between the second end 2213 of the movable connecting member 221 and the bracket 21. The sliding connection and plugging between the second end 2213 of the movable connecting member 221 and the bracket 21 will be used as an exemplary embodiment for specific description below:

[0048] In a possible implementation, the second end 2213 of the movable connecting member 221 and the bracket 21 are slidably connected to achieve an adjustable distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X. Specifically, the first end 2212 of the movable connecting member 221 is provided with a slide plate 2211, and the bracket 21 is provided with a slide rail 211 extending toward the second direction X, and the slide plate 2211 is slidably connected to the slide rail 211.

[0049] In this embodiment, the first end 2212 of the movable connection member 221 can be connected to the slide 2211 by welding, threading, gluing, etc. The slide 2211 can be a square sheet structure, a circular sheet structure, or a sheet structure of its nature. The slide rail 211 is a slide groove structure opened on the side of the bracket 21 in the second direction X, that is, the slide rail 211 has a slideway extending along the second direction X. In this way, after the slide 2211 is slidably connected in the slide rail 211, when the specification of the electrical component 1 changes and the connection position of the electrical component 1 and the bracket 21 changes, the slide 2211 slides in the slide rail 211 to adjust the distance between the movable connection member 221 and the fixed connection member 222 in the second direction X, so that the bracket 21 can adapt to different types of electrical components 1. Specifically, when the size of the electrical component 1 in the second direction X is large, the slide 2211 can slide in the slide rail 211 along the second direction X in a manner away from the fixed connection member 222, so that the distance between the movable connection member 221 and the fixed connection member 222 in the second direction X increases. On the contrary, when the size of the electrical component 1 in the second direction X is small, the slide 2211 can slide in the slide rail 211 along the second direction X in a manner away from the fixed connection member 222, so that the distance between the movable connection member 221 and the fixed connection member 222 in the second direction X decreases.

[0050] For the above-mentioned embodiment, in some embodiments, a sliding protrusion is further provided at the bottom of the first end 2212 of the movable connecting member 221; the slide rail 211 includes a sliding groove extending along the second direction X, and the sliding protrusion slides in the sliding groove; wherein the size of the sliding protrusion in the third direction Y is smaller than the size of the movable connecting member 221 in the third direction Y, wherein the third direction Y intersects with the second direction X and the first direction Z at the same time.

[0051] In this embodiment, the sliding protrusion can be a cylindrical block structure, a prismatic block structure or a block structure of other shapes arranged at the bottom of the first end 2212 of the movable connecting member 221. The bottom of the first end 2212 of the movable connecting member 221 and the sliding protrusion can be fixed by welding, threaded connection, etc. Since the size of the sliding protrusion in the third direction Y is smaller than the size of the movable connecting member 221 in the third direction Y, the cross-sectional area of ​​the sliding protrusion in the first plane can also be smaller than the cross-sectional area of ​​the movable connecting member 221 in the first plane, wherein the first plane is a plane formed by the second direction X and the third direction Y. In this way, the part sliding in the slide groove can be the sliding protrusion, and then the movable connecting member 221 can limit the sliding protrusion in the first direction Z to prevent the sliding protrusion and the slide 2211 from falling off in the first direction Z during the sliding process, thereby ensuring the stability of the sliding.

[0052] For the above-mentioned embodiment, in some other embodiments, the slide rail 211 includes a first slide groove 2111 and a second slide groove 2112, the first slide groove 2111 and the second slide groove 2112 are connected, the first slide groove 2111 and the first end 2212 of the movable connecting member 221 are slidably connected, and the first slide groove 2111 and the second slide groove 2112 both extend along the second direction X; wherein, the orthographic projection of the first slide groove 2111 in the first direction Z is located in the second slide groove 2112, and the slide 2211 is slidably connected in the second slide groove 2112.

[0053] In this embodiment, since the slide rail 211 includes a first slide groove 2111 and a second slide groove 2112, the first slide groove 2111 and the second slide groove 2112 are connected, the first slide groove 2111 and the second slide groove 2112 both extend along the second direction X, and the orthographic projection of the first slide groove 2111 in the first direction Z is located in the second slide groove 2112, the first slide groove 2111 and the second slide groove 2112 constitute a two-layer slideway structure. Since the first slide groove 2111 and the first end 2212 of the movable connecting member 221 are slidably connected, and the slide plate 2211 is slidably connected in the second slide groove 2112, the movable connecting member 221 can slide in the first slide groove 2111, and the slide plate 2211 can slide in the second slide groove 2112. In this way, by providing the first slide groove 2111 and the second slide groove 2112 , the slide plate 2211 and the movable connecting member 221 can slide in different slideways, thereby facilitating the sliding of the slide plate 2211 .

[0054] For the above-mentioned implementation manner, in some embodiments, the size of the slide 2211 in the third direction Y is larger than the size of the first slide groove 2111 in the third direction Y, wherein the third direction Y intersects the second direction X and the first direction Z. In this way, since the size of the slide 2211 in the third direction Y is larger than the size of the first slide groove 2111 in the third direction Y, the area of ​​the orthographic projection of the slide 2211 on the first plane is larger than the orthographic projection of the first slide groove 2111 on the first plane, and then the slide 2211 can be limited by the parts of the first slide groove 2111 on both sides of the third direction Y, that is, the slide 2211 is limited in the first direction Z, so as to prevent the slide 2211 from falling off in the first direction Z during the sliding process, thereby ensuring the stability of the sliding.

[0055] Furthermore, the dimension of the first slide groove 2111 in the second direction X is smaller than the dimension of the second slide groove 2112 in the second direction X. Thus, since the dimension of the first slide groove 2111 in the second direction X is smaller than the dimension of the second slide groove 2112 in the second direction X, the slide plate 2211 has sufficient space in the second direction X, thereby preventing the slide plate 2211 from being unable to slide in the second direction X before sliding to a predetermined position.

[0056] In some exemplary embodiments, the movable connecting member 221 is a stud, and the diameter of the stud is less than or equal to the size of the first slide groove 2111 in the third direction Y, wherein the third direction Y intersects with the second direction X and the first direction Z. In this way, since the diameter of the stud is less than or equal to the size of the first slide groove 2111 in the third direction Y, it is possible to ensure that the stud slides in the first slide groove 2111. In addition, it should be noted that the stud may be a columnar structure with a consistent size in the third direction Y, or a columnar structure with inconsistent sizes in the third direction Y. For example, the size of the end of the stud away from the bracket 21 in the third direction Y may be smaller than the size of the end of the stud close to the bracket 21 in the third direction Y, or the size of the end of the stud away from the bracket 21 in the third direction Y may be larger than the size of the end of the stud close to the bracket 21 in the third direction Y. When the stud is a columnar structure with inconsistent dimensions in the third direction Y, the solution in the above embodiment can be implemented by simply ensuring that the diameter of the end of the stud close to the bracket 21 is less than or equal to the dimension of the first slide groove 2111 in the third direction Y.

[0057] In some optional embodiments, the electrical box assembly also includes a limit member; a first limit hole is opened on the slide 2211, and a second limit hole is opened on the bracket 21, and the axis of the first limit hole and the axis of the second limit hole are in the same straight line in the first direction Z; the limit member passes through the first limit hole and the second limit hole.

[0058] It should be noted that in the above embodiments, the limiting member may be a screw rod, a clamping rod or other limiting structures, and the structures of the first limiting hole and the second limiting hole are determined according to the type of the limiting member. Exemplarily, when the limiting member is a screw rod, the first limiting hole and the second limiting hole are both threaded holes, and when the limiting member is a clamping rod, the first limiting hole and the second limiting hole are both clamping holes. In some embodiments, when the limiting member is a clamping rod, and the first limiting hole and the second limiting hole are both clamping holes, a clamping protrusion structure may be provided on the clamping rod, and limiting holes may be provided in the first limiting groove and the second limiting groove, so as to further ensure the limiting effect. It should also be noted that the number of the first limiting holes and the second limiting holes are both multiple, and the multiple first limiting holes are arranged at intervals along the second direction X, and the multiple second limiting holes are arranged at intervals along the second direction X. Each first limiting hole has the first and second limiting holes in the same straight line in the first direction Z. In this way, electrical components 1 of different specifications can have first limiting holes and second limiting holes in different positions after connection to cooperate with the limiting component for limiting.

[0059] Thus, in the above embodiment, when the slide 2211 slides in the slide rail 211 so that the distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X reaches a preset distance, the limiting member can pass through the first limiting hole and the second limiting hole to lock the slide 2211 and ensure that the first end 2212 of the movable connecting member 221 maintains the stability of its position.

[0060] With respect to the above-mentioned embodiments, in other embodiments, a lock buckle is provided in the slide rail 211 ; when the slide plate 2211 slides to a preset position along the second direction X, the lock buckle locks the slide plate 2211 .

[0061] It should be noted that the locking structure may include at least one of a spring, a spring sheet and other snap structures. Exemplarily, the locking structure includes a first snap and a second snap that are arranged opposite to each other in the first direction Z. In other words, the first snap and the second snap are located on two surfaces of the slide 2211 in the first direction Z, and the first snap and the second snap are both elastic claw structures. In this way, after the slide 2211 slides between the first snap and the second snap, the first snap and the second snap are deformed after being subjected to force, so that the first snap and the second snap have elastic force on the slide 2211 in the first direction Z, so that the first snap and the second snap can constitute an elastic limit for the slide 2211. In this way, not only can the slide 2211 be locked, but also the relative position of the slide 2211 in the slide rail 211 can be changed easily.

[0062] In another possible implementation, the second end 2213 of the movable connector 221 and the bracket 21 are plugged together to achieve an adjustable distance between the movable connector 221 and the fixed connector 222 in the second direction X. Specifically, a connecting rod is provided at the first end 2212 of the movable connector 221, and a plurality of connecting holes spaced apart along the second direction X are provided at the top of the bracket 21, and the connecting rods are plugged into the connecting holes.

[0063] It should be noted that, in this embodiment, since the first end 2212 of the movable connector 221 is provided with a connecting rod, and the top of the bracket 21 is provided with a plurality of connecting holes arranged at intervals along the second direction X, when the size of the electrical component 1 in the second direction X is large, the connecting rod can be inserted into the connecting hole close to the fixed connector 222, so that the distance between the movable connector 221 and the fixed connector 222 in the second direction X is increased. On the contrary, when the size of the electrical component 1 in the second direction X is small, the connecting rod can be inserted into the connecting hole far away from the fixed connector 222, so that the distance between the movable connector 221 and the fixed connector 222 in the second direction X is reduced. In this way, the bracket 21 can also adapt to different types of electrical components 1. It should also be noted that the number of connecting holes should be multiple, and the distance between each connecting hole and the fixed connector 222 is determined according to the size of different types of electrical components 1 in the second direction X, and then the connecting rod can be inserted into different connecting holes to achieve the purpose of adjusting the distance between the movable connector 221 and the fixed connector 222 in the second direction X.

[0064] For the above embodiment, further, in the second direction X, the spacing between each two adjacent connection holes is equal. In this way, it is convenient to adjust the distance between the movable connection member 221 and the fixed connection member 222 in the second direction X by inserting the connection rod into different connection holes.

[0065] Regarding the connection method between the fixed connector 222, the movable connector 221 and the electrical component 1, in some embodiments, the side wall of the electrical component 1 is provided with at least a first ear seat 11 and a second ear seat 12 which are in relative positions in the second direction X; the movable connector 221 is detachably connected to the first ear seat 11, and the fixed connector 222 is detachably connected to the second ear seat 12.

[0066] It should be noted that, in this embodiment, the first ear seat 11 and the second ear seat 12 can be a plate-like structure protruding from the side wall of the electrical component 1, and the first ear seat 11 and the second ear seat 12 can also be provided with different structures according to the specific types of the fixed connector 222 and the movable connector 221. Exemplarily, in the case where the fixed connector 222 and the movable connector 221 are both screws, the first ear seat 11 and the second ear seat 12 can be provided with threaded holes, and in the case where the fixed connector 222 and the movable connector 221 are both clamping rods, the first ear seat 11 and the second ear seat 12 can be provided with clamping holes. In this way, since the movable connector 221 is detachably connected to the first ear seat 11 and the fixed connector 222 is detachably connected to the second ear seat 12, it is convenient to disassemble and assemble the electrical component 1 and the bracket 21.

[0067] It can be seen from the above embodiments that in the embodiment of the utility model, since the fixed connecting member 222 is fixed to the bracket 21 at one end in the first direction Z, the other end of the fixed connecting member 222 in the first direction Z is detachably connected to the electrical component 1, the first end 2212 of the movable connecting member 221 is movably connected to the bracket 21, and the second end 2213 of the movable connecting member 221 is detachably connected to the electrical component 1, so that the distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X is adjustable. Therefore, when the specification of the electrical component 1 changes, resulting in a change in the connection position of the electrical component 1 and the bracket 21, the distance between the movable connecting member 221 and the fixed connecting member 222 in the second direction X can be adjusted, so that the bracket 21 can adapt to different types of electrical components 1. In this way, even if the specification of the electrical component 1 changes, there is no need to change the bracket 21, so that the bracket 21 can install a variety of electrical components 1 of different specifications, thereby saving the cost of redesigning and making molds for the bracket 21, and improving the production efficiency of the battery pack.
