The fixing boss 301 is arranged on the upper surface of the fixing base 302, the fixing boss 301 is flat, and the fixing boss 301 is arranged parallel to the upper surface of the fixing base 302, so that an insertion interlayer 303 is formed between the fixing boss 301 and the upper surface of the fixing base 302, and the fixing part 101 can be inserted into the insertion interlayer 303.

[0055] The fixing boss 301 is provided with a through hole 3011, and the fixing base 302 is provided with a fixing groove 3021 with an opening facing upward. The through hole 3011 on the fixing boss 301 is arranged opposite to the opening of the fixing groove 3021, so that the movable pin 2 can pass through the through hole 3011 and the fixing groove 3021 and connect with the inner wall of the fixing groove 3021. When the fixing part 101 is plugged into the plug-in interlayer 303, the opening of the fixing part 101 is opposite to the movable pin 2, so that the fixing part 101 can be plugged into the plug-in interlayer 303, and the part of the movable pin 2 located in the plug-in interlayer 303 can enter the fixing area 102 of the fixing part 101 through the opening, so that the fixing part 101 can be mutually engaged with the movable pin 2.

[0056] Preferably, the upper surface of the fixed boss 301 is also provided with a rotation direction indicator for indicating the operation of the movable pin 2 to rotate it. By rotating the movable pin 2 in the direction indicated by the rotation direction indicator 3012, the movable pin 2 and the fixed seat 3 can be changed from a locked state to an unlocked state.

[0057] Furthermore, the axis of the fixed groove 3021 extends in the vertical direction, and a first slide groove 3021a and a second slide groove 3021b are formed at a local position of the inner wall surface of the fixed groove 3021. The first slide groove 3021a and the second slide groove 3021b are arranged side by side along the circumference of the fixed groove 3021, and the first slide groove 3021a and the second slide groove 3021b are connected to each other in the horizontal direction, and the bottom of the first slide groove 3021a is flush with the bottom of the second slide groove 3021b.

[0058] exist Figure 6From the perspective shown, the height of the first slide groove 3021a is greater than the height of the second slide groove 3021b, the width of the second slide groove 3021b is greater than the width of the first slide groove 3021a, and a first limit block 304a is provided at the top of the first slide groove 3021a. The first limit block 304a is flush with the upper surface of the fixed base 302, the first limit block 304a is located in the first slide groove 3021a, and the first limit block 304a blocks the top port of the first slide groove 3021a.

[0059] Preferably, the second slide groove 3021b has a top surface, a side wall surface of the first slide groove 3021a close to the second slide groove 3021b is vertically arranged to the top surface of the second slide groove 3021b, and a second limit block is arranged on the top surface of the first slide groove 3021a at the intersection with the side wall surface of the first slide groove 3021a, and the second limit block protrudes relative to the top surface of the first slide groove 3021a.

[0060] Further, the movable pin 2 includes: an operating portion 201, a first limiting portion 202, and a second limiting portion 203, and also includes a rod 205. The operating portion 201, the rod 205, the first limiting portion 202, and the second limiting portion 203 are arranged in sequence from top to bottom. Preferably, the operating portion 201, the rod 205, the first limiting portion 202, and the second limiting portion 203 have an integrated structure. The operating portion 201 is cylindrical, and the rod 205 is arranged on the lower surface of the operating portion 201. The diameter of the operating portion 201 is greater than the diameter of the rod 205. When the movable pin 2 is locked or unlocked with the fixed seat 3, the staff can adjust the relative position of the movable pin 2 and the fixed seat 3 by pulling and rotating the operating portion 201, thereby realizing the locking or unlocking of the movable pin 2 and the fixed seat 3. The specific operation process is described in detail below.

[0061] The rod portion 205 is arranged between the operating portion 201 and the first limiting portion 202. The operating portion 201 and the first limiting portion 202 are connected through the rod portion 205. The diameter of the rod portion 205 is smaller than the diameter of the first limiting portion 202. The diameter of the first limiting portion 202 is smaller than the diameter of the through hole 3011 on the fixed boss 301, so that when the operating portion 201 is pulled, the first limiting portion 202 can be inserted into the through hole 3011 and move axially relative to the fixed boss 301.

[0062] The second limiting portion 203 is disposed below the first limiting portion 202. The diameter of the second limiting portion 203 is greater than the diameter of the through hole 3011, so that the second limiting portion 203 is always located below the fixed boss 301. The diameter of the second limiting portion 203 is smaller than the diameter of the fixed groove 3021 of the fixed base 302, so that the second limiting portion 203 can be inserted into the fixed groove 3021 and delay axial movement. The outer wall surface of the second limiting portion 203 is provided with a convex portion 204, which is used to limit to the first slide groove 3021a or the second slide groove 3021b and reciprocate between the two. Preferably, the protrusion 204 is in the shape of an elongated strip, and the length of the protrusion 204 extends along the height direction of the second limiting portion 203, and the height of the protrusion 204 is less than the height of the second limiting portion 203, so that the radial width of the second limiting portion 203 at the position where the protrusion 204 is provided is greater than the width of other positions of the second limiting portion 203, and the protrusion 204 is located in the first slide groove 3021a or the second slide groove 3021b, which limits the axial movement of the second limiting portion 203, and the second limiting portion 203 will not detach from the fixing groove 3021.

[0063] It should be noted that the height of the protrusion 204 is smaller than the height of the second slide groove 3021b, so that the protrusion 204 can be limited in the second slide groove 3021b, and under the blocking action of the second limit block 304b, the protrusion 204 can be prevented from accidentally falling out of the second slide groove 3021b. When the hand-held operating part 201 causes the movable pin 2 to rotate as a whole, the movable pin 2 is first pushed downward to make the protrusion 204 avoid the second limit block 304b and thus shift to the second slide groove 3021b below the second limit block 304b, thereby realizing that the protrusion 204 can switch positions between the second slide groove 3021b and the first slide groove 3021a.

[0064] The second position-limiting portion 203 is hollow inside and has a groove structure with an opening downward. The elastic support member 4 can be a compression spring. The elastic support member 4 is arranged in the fixing groove 3021. The upper end of the elastic support member 4 enters the second position-limiting portion 203 and abuts against the second position-limiting portion 203. Preferably, the elastic support member 4 is fixedly connected to the second position-limiting portion 203. The lower end of the elastic support member 4 abuts against the bottom wall of the fixing groove 3021, so that the elastic support member 4 can support the movable pin 2. When the movable pin 2 is operated, the telescopic state of the elastic support member 4 changes to accumulate or release elastic potential energy.

[0065] Preferably, the number of the protrusions 204 is two or more, and all the protrusions 204 are centrally symmetrically arranged about the axis of the second limiting portion 203. One first slide groove 3021a and one second slide groove 3021b are arranged in groups, and the number of groups of the first slide groove 3021a and the second slide groove 3021b is the same as the number of the protrusions 204 and corresponds one to one.

[0066] Furthermore, a status indicator 2011 is provided on the end face of the operating portion 201 facing away from the rod portion 205, an installation indicator 1011 for cooperating with the status indicator 2011 is provided on the fixing portion 101, and an observation window is provided on the fixing boss 301 opposite to the installation indicator 1011, through which the installation indicator 1011 can be intuitively seen.

[0067] Furthermore, in the present embodiment, the number of fixing seats 3 is multiple, and the number of fixing parts 101 matches the number of fixing seats 3. Preferably, in the present embodiment, the number of fixing parts 101 is four, and the four fixing seats 3 are respectively arranged at the four top corners of the bracket body 1. The bracket body 1 is fixed to the designated position by the four fixing seats 3 to ensure the stability of the bracket body 1 after being installed at the designated position. Of course, the number of fixing seats 3 is not limited to four, and the setting position of the fixing seat 3 relative to the bracket body 1 is not limited to the top corner of the bracket body 1. The number of fixing seats 3 and the setting position relative to the bracket body 1 can be determined according to the actual installation environment and installation conditions of the bracket body 1.

[0068] The quick-insert installation bracket provided in the present application is in a state where, when the protrusion 204 of the movable pin 2 is located in the second slide groove 3021b, the movable pin 2 and the fixed seat 3 are in a mutually unlocked state. At this time, the first limiting portion 202 is located outside the fixed area 102 of the fixed portion 101. Specifically, at this time, the first limiting portion 202 is located below the fixed area 102, and the rod portion 205 of the movable pin 2 is located in the fixed area 102. Since the diameter of the rod portion 205 is relatively small, at this time, the fixed portion 101 can be inserted into the plug-in interlayer 303, or the fixed portion 101 can be separated from the rod portion 205.

[0069] Rotate the movable pin 2 in the direction of the rotation direction indicator 3012, and the protrusion 204 can be shifted from the second slide groove 3021b to the first slide groove 3021a. Since the height of the first slide groove 3021a is greater than the height of the second slide groove 3021b, the movable pin 2 is pulled upward and the elastic support member 4 applies elastic force to the movable pin 2, so that the movable pin 2 moves upward as a whole, and the first limiting portion 202 is simultaneously moved upward to the first limiting portion 202 entering the fixed area 102. The first limiting portion 202 is engaged with the fixed portion 101. Since the diameter of the first limiting portion 202 is larger , the first limiting portion 202 will not detach from the fixed area 102, so that the movable pin 2 and the fixed portion 101 remain fixed, and the movable pin 2 and the fixed seat 3 are transformed into a locked state. Under the support of the elastic support member 4, the movable pin 2 will not move downward. In the absence of external force on the operating portion 201, the movable pin 2 and the fixed seat 3 can remain in the current state, and at this time, the status indicator 2011 on the operating portion 201 is flush with the installation indicator 1011 visible through the observation port 305, and the staff can know that the movable pin 2 and the fixed seat 3 are in a locked state at this time.

[0070] To sum up, the quick-plug mounting bracket provided in the present application can realize the quick disassembly and assembly of the bracket body 1 and the fixing seat 3 without the need for bolt connection, torque setting and other operations. It is simple to operate and does not require special tools. It simplifies the disassembly and assembly steps and the complexity of the quick-plug mounting bracket, thereby significantly improving the assembly efficiency of the equipment using the quick-plug mounting bracket.

[0072] The battery pack further includes: a box body and a BMS. The fixing seat 3 is connected to the box body, so as to fix the above-mentioned quick-insert mounting bracket in the box body. Preferably, the fixing seat 3 is fixedly connected to the box body, and the connection method can be but is not limited to welding.

[0073] The bracket body 1 is provided with a mounting portion 5 , and the BMS is connected to the mounting portion 5 , so that the BMS is fixed on the bracket body 1 , and further the BMS is stably disposed in the box.

[0074] Preferably, there are multiple mounting parts 5, and the BMS and the bracket body 1 are fixed through multiple connection points.

[0075] Preferably, the mounting portion 5 is specifically a mounting hole that passes through the upper and lower surfaces of the bracket body 1. A hole is opened at the position of the BMS corresponding to the mounting hole. The BMS and the mounting portion 5 can be connected by using fasteners to pass through the mounting portion 5 and the BMS. The fasteners can be rivets, bolts with nuts, etc., which are not specifically limited here.

[0076] Furthermore, the battery pack also includes a connecting ear plate 6, which is arranged on the connecting piece 103 on the bracket body 1, and the connecting ear plate 6 is provided with a fixing hole for fixing the wiring harness of the battery pack. Specifically, the wiring harness can be organized and fixed by passing a cable tie through the fixing hole and bundling the wiring harness with the cable tie.

[0077] The battery pack provided in the present application stably installs the BMS in the box through the above-mentioned quick-plug installation bracket, ensuring the stability of the BMS in the box, thereby ensuring smooth charging and discharging of the battery pack, and the bracket body 1 supports the BMS, and the space below the bracket body 1 can also be used to install other necessary parts of the battery pack, making full use of the internal space of the box, which is conducive to controlling the volume of the battery pack.
