Description

Technical Field

[0001] The present application relates to the field of battery technology, and more specifically, to a liner assembly tool, an assembly device, and a battery production system. Background Art

[0002] Battery devices are widely used in electronic devices, such as mobile phones, laptop computers, battery cars, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and electric tools, etc.

[0003] In the production process of battery devices, it is necessary to install protective bushings in the mounting holes of the mounting structures such as the upper cover of the battery device. The relevant technology is to manually press the bushings directly into the mounting holes after being coated with glue. It is difficult to control the pressing depth of the bushings and the thickness of the glue layer after pressing by manual operation, which affects the protective performance of the bushings after installation. Therefore, how to better control the pressing depth of the bushings installed into the mounting holes and the thickness of the glue layer after pressing is a research direction in battery technology.

[0071] Below, the embodiments of the present application are described in detail.

[0072] At present, the application of battery devices is becoming more and more extensive. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0073] Metal fasteners such as screws need to be installed on mounting structures such as the upper cover of the battery device. Since the mounting structures are mostly made of composite materials, directly setting screw holes on the mounting structures to connect with fasteners such as screws can easily cause damage to the mounting holes. Therefore, the relevant technology uses bushings to be bonded to the mounting holes, which are connected with fasteners such as screws to protect the mounting holes of the mounting structures.

[0074] The existing method of installing the bushing is usually to manually place the bushing on the mounting structure and then press it. This method cannot control the pressing force and pressing depth, and cannot meet the requirement of raising the bushing to a specific size (for example, 0.6mm) above the surface of the mounting structure. In addition, the pressing depth of the bushing directly affects the thickness of the glue layer between the bushing and the mounting hole. Therefore, this method cannot control the thickness of the glue layer between the bushing and the mounting hole, which easily leads to too little bonding force between the two. In addition, when the manual pressing force is too large, there is a possibility of damaging the mounting structure, and the existing bushing installation method cannot meet the needs of mass production.

[0075] Therefore, how to better control the installation depth of the bushing and the thickness of the glue layer between the bushing and the mounting hole is an important issue in battery production and processing.

[0076] In view of this, the present application provides a technical solution, in which a first pair of locking parts and a second pair of locking parts are arranged on the bushing assembly tooling, and the two are threadedly connected. The downward pressure of the bushing is achieved by rotating the second pair of locking parts. The threaded connection and rotation method can better control the downward pressure of the bushing, the downward pressure depth and the thickness of the rubber layer between the bushing and the mounting hole.

[0077] The following is combined with Figure 1-7 The bushing assembly tool 100 and bushing assembly equipment 1000 provided in the embodiment of the present application are introduced.

[0078] Combined with Figure 1-3 As shown, an embodiment of the present application provides a bushing assembly tool 100 for installing a bushing 2000 in a mounting hole of a mounting structure 3000, including a first pair of locking members 10 and a second pair of locking members 20, the first pair of locking members 10 having opposite first surfaces 11 and second surfaces 12, the first surface 11 being used to support the mounting structure 3000, and being provided with an avoidance groove 111 for accommodating part of the bushing 2000, the first pair of locking members 10 being provided with a first connecting portion 13 for facing the mounting hole; the second pair of locking members 20 including a second connecting portion 21 and a pressing portion 22 connected to each other, the pressing portion 22 being arranged facing the first surface 11, the second connecting portion 21 and the first connecting portion 13 being connected, and being guided and matched along the arrangement direction from the first surface 11 to the second surface 12, the pressing portion 22 being arranged facing the first surface 11, and being used to press down the bushing 2000.

[0079] The first pair of locking members 10 may be plate-shaped or block-shaped, and their cross-sectional shapes may be circular, rectangular, or waist-shaped as shown in the figure, which are not listed one by one in this embodiment.

[0080] The first pair of locking members 10 and the second pair of locking members 20 can both be metal members or non-metal members (such as plastic) with a certain structural strength, as long as they can meet the strength requirements. This embodiment does not impose too many restrictions on this.

[0081] The "locking" in the first pair of locking members 10 and the second pair of locking members 20 of this embodiment means that the two can cooperate with each other to lock the bushing 2000 to the mounting structure 3000. During the locking process, the two drive the second pair of locking members 20 to press down the bushing 2000.

[0082] The connection method between the second connection part 21 and the first connection part 13 can be plug-in, sliding connection, or the following threaded connection. The above method can not only realize the docking of the first pair of locking members 10 and the second pair of locking members 20, but also enable the second connection part 21 and the first connection part 13 to be guided and matched along the direction from the first surface 11 to the second surface 12.

[0083] It should be noted that the arrangement direction from the first surface 11 to the second surface 12 (the third direction Z in the figure) has two opposite sub-directions. For example, when the arrangement direction from the first surface 11 to the second surface 12 is the vertical direction in the figure, it can include a top-to-bottom direction and a bottom-to-top direction. The first direction X and the second direction Z described below also have two opposite sub-directions, respectively.

[0084] The first pair of locking elements 10 has a first surface 11 and a second surface 12 opposite to each other. When the bushing 2000 is installed, the first surface 11 may be an upper surface, and the second surface 12 may be a lower surface.

[0085] The first surface 11 is provided with an avoidance groove 111, the shape of which can match the shape of the lower end of the bushing 2000. For example, the cross-sections of the avoidance groove 111 and the bushing 2000 can be annular or circular, etc. The size of the avoidance groove 111 can be larger than the size of the lower end of the bushing 2000, thereby facilitating the entry of the lower end of the bushing 2000.

[0086] The first connection portion 13 is located in the avoidance groove 111 and is disposed facing the mounting hole (not shown in the figure), so that the second connection portion 21 passing through the mounting hole can pass through the mounting hole and connect with the first connection portion 13 .

[0087] In some embodiments, the mounting structure 3000 may be an upper cover of a box of the battery device. Of course, the mounting structure 3000 may also be other structures of the battery device, such as a side wall of the box.

[0088] When the bushing assembly tool 100 of the mounting structure 3000 is used to assemble the bushing 2000, the mounting structure 3000 is placed on the first pair of locking members 10, and then the second pair of locking members 20 are driven to descend, thereby driving the pressing portion 22 to press down the bushing 2000. Compared with the method of directly pressing down the bushing 2000 manually, this method can better control the pressing direction and pressing stroke of the bushing 2000, thereby controlling the depth of the bushing 2000 pressed into the mounting hole and the thickness of the glue layer between the bushing 2000 and the mounting hole, thereby improving the protection performance of the bushing 2000 after installation, and reducing the possibility of damaging the mounting structure 3000 due to excessive downward pressure on the bushing 2000.

[0089] In some examples, optionally, the first connection portion 13 and the second connection portion 21 are threadedly connected.

[0090] The first connection portion 13 and the second connection portion 21 are threadedly connected, which means that one of the first connection portion 13 and the second connection portion 21 is provided with an internal thread, and the other is provided with an external thread.

[0091] Combined with Figure 2 and 3 As shown, in some examples, optionally, the first connection portion 13 includes a screw hole 131 , and the second connection portion 21 includes a screw rod 211 connected to the screw hole 131 .

[0092] The screw hole 131 is directly opened in the avoidance groove 111, the inner wall of the screw hole 131 is provided with an internal thread, and the outer wall of the screw rod 211 is provided with an external thread. When the screw rod 211 rotates into the screw hole 131, the internal thread and the external thread are matched and connected, so that the screw rod 211 can descend or rise during the rotation process.

[0093] When the screw rod 211 descends, the pressing portion 22 presses down the bushing 2000 , so that the glue layer between a part of the outer wall surface of the bushing 2000 and the inner wall surface of the mounting hole can be compressed.

[0094] In this embodiment, the first connection portion 13 is designed to include a screw hole 131, and the second connection portion 21 includes a screw rod 211. The structure is simple, and the second pair of locking members 20 can be pressed down by just rotating the screw rod 211, which is easy to operate.

[0095] In some examples, optionally, a connecting boss 112 is provided on the bottom wall of the avoidance groove 111 . The connecting boss 112 is higher than the first surface 11 or flush with the first surface 11 . The screw hole 131 is opened on the connecting boss 112 .

[0096] The upper end of the connecting boss 112 may be flush with the first surface 11 , or the upper end of the connecting boss 112 may be higher than the first surface 11 in this embodiment.

[0097] The connecting boss 112 may be a cylindrical shape with a cross section approximately similar to a circle, or may be other shapes. The connecting boss 112 may be integrally formed with the avoidance groove 111 during processing.

[0098] The screw hole 131 of the present embodiment is provided on the connecting boss 112 , so that the height of the screw hole 131 can be raised by the connecting boss 112 , thereby facilitating the connection between the screw rod 211 and the screw hole 131 .

[0099] In some examples, optionally, the screw hole 131 passes through the second surface 12 .

[0100] The upper end of the screw hole 131 passes through the upper end of the connecting boss 112, and the lower end of the screw hole 131 passes through the second surface 12. Compared with the structure without the connecting boss 112 and the screw hole 131 not passing through the second surface 12, the length of the screw hole 131 located on the connecting boss 112 and passing through the second surface 12 is greater.

[0101] In this embodiment, the screw hole 131 is designed to pass through the second surface 12, with the lower end of the screw hole 131 located on the second surface 12 and the upper end flush with or higher than the first surface 11, so that the overall length of the screw hole 131 is greater than or equal to the thickness of the first pair of locking members 10, thereby extending the matching stroke between the screw rod 211 and the screw hole 131 and improving the stability of the screw rod 211 during rotation.

[0102] Combined with Figure 1-3 As shown, in some examples, optionally, the bushing assembly tool 100 further includes a distance detection member 30 , which is connected to the second pair of locking members 20 and is at least partially located in the avoidance groove 111 , and is used to detect the distance between itself and the bushing 2000 .

[0103] The first pair of locks 10 may be provided with a first mounting hole 14, which may be a through hole, and the distance detection member 30 may be inserted into the first mounting hole 14, and the lower end of the distance detection member 30 may extend out of the second surface 12 of the first pair of locks 10 and the bottom surface of the base 40 described below.

[0104] The detection head of the distance detection member 30 is located in the avoidance groove 111. The distance detection member 30 can be a distance sensor, such as an ultrasonic distance sensor, a laser distance sensor, an infrared distance sensor, a radar sensor, a photoelectric sensor, etc., which are not listed one by one in this embodiment.

[0105] The bushing 2000 may have a preset distance from the distance detection member 30 (e.g., 0.1 mm-10 mm) when installed. Under the premise of meeting the preset value, the bushing 2000 may be higher than a specific dimension (e.g., 0.6 mm) of the surface of the mounting structure 3000. Moreover, under this preset value, the thickness of the adhesive layer between the bushing 2000 and the mounting hole (e.g., ) meets the design requirements.

[0106] The distance detecting member 30 detects the distance between itself and the bushing 2000 . The distance detecting member 30 may be connected to a display component for displaying the above distance or a broadcasting component for broadcasting the distance by sound, and may also be connected to a control component (not shown in the figure).

[0107] In addition, the control component is used to determine whether the distance between the distance detection component 30 and the bushing 2000 is within a preset value. The distance detection component 30 can be connected to the above-mentioned display component or broadcast component through the control component.

[0108] In addition, the distance detecting member 30 can be used to detect the distance between itself and the bushing 2000, so as to obtain the distance of the bushing 2000 being pressed down. Specifically, the control component or the distance detecting member 30 itself may store the distance between the distance detecting member 30 and the bushing 2000 before being pressed down when the bushing 2000 is located on the mounting hole and not pressed down. Then, when the bushing 2000 is pressed down, the distance between the distance detecting member 30 and the bottom end of the bushing 2000 detected in real time by the distance detecting member 30 is compared with the above-mentioned distance before being pressed down, so as to obtain the distance of the bushing 2000 being pressed down.

[0109] By detecting the distance detection part 30, it is possible to know whether the distance between the bushing 2000 and the distance detection part 30 is within the design range, or to know the distance that the bushing 2000 is pressed down, so as to facilitate the operator to know the distance that the bushing 2000 is pressed down, so as to better control the depth of the bushing 2000 pressed down into the mounting hole and the thickness of the glue layer between the bushing 2000 and the mounting hole.

[0110] In some examples, optionally, the bushing assembly tool 100 further includes an alarm component (not shown in the figure), which is communicatively connected to the distance detection component 30 and is used to issue an alarm when the distance detection component 30 detects that the distance to the bushing 2000 exceeds a preset value.

[0111] The alarm device may be a sound alarm that uses sound to alarm, or a light alarm that uses light to alarm, or an audible and visual alarm that uses both sound and light to alarm.

[0112] The distance detection element 30 may have a built-in control circuit, and the alarm element may be connected and opened and closed through the control circuit. Alternatively, the distance detection element 30 and the alarm element may be connected and communicated through an external control component (not shown in the figure).

[0113] The alarm component can be directly installed on the distance detection component 30 through mechanical connection, or can be externally mounted on the distance detection component 30.

[0114] When the distance detection member 30 detects that the bushing 2000 has descended beyond a preset value, or when the distance detection member 30 detects that the distance to the bushing 2000 exceeds a preset value, the alarm member of this embodiment issues a warning to warn the operator or the control component to remind the operator to stop operating the following driving device to rotate the second pair of locks 20, or the control component directly stops the driving device from driving the second pair of locks 20 to rotate, thereby further reducing the possibility of the bushing 2000 being pressed down too much.

[0115] In some examples, optionally, a third connection portion 23 is provided at one end of the second pair of locking elements 20 away from the first connection portion 13, and the third connection portion 23 is used to connect to an external driving device (not shown in the figure), which is used to drive the second pair of locking elements 20 to rotate.

[0116] The reason for configuring the third connecting portion 23 is that if the second pair of locking members 20 are rotated manually, it not only wastes manpower but also has low rotation efficiency and cannot perform the quick press-down installation of the bushing 2000 .

[0117] Therefore, in this embodiment, a third connection portion 23 is provided at the first end of the second pair of locking members 20 away from the first connection portion 13. The third connection portion 23 can be directly provided at the end of the screw 211 away from the first connection, or a nut 232 having a radial dimension greater than that of the screw 211 can be provided on the screw 211 away from the third connection portion 23, and the third connection portion 23 is provided on the nut 232.

[0118] The third connection portion 23 and the driving device can be connected in a mechanically detachable manner such as plug-in or clip-on connection, so as to facilitate the disassembly and assembly of the two.

[0119] The driving device is a driving structure for providing torque to the screw 211, which may include an electric drill having a connected motor and a rotatable drill bit, wherein the output shaft of the motor drives the drill bit to rotate, and the drill bit is used to connect to the third connecting part 23 and to drive the screw 211 and the pressing part 22 to rotate through the third connecting part 23.

[0120] Of course, the structural form of the driving device is not limited thereto, and any structure that can be connected to the third connecting portion 23 and provide torque can be used as the driving device mentioned in this embodiment.

[0121] The above structure is provided with a third connecting part 23 on the second pair of locking members 20, which is connected to an external driving device through the third connecting part 23. The driving device drives the second pair of locking members 20 to rotate to realize the downward pressing of the pressing part 22, thereby realizing the automation of the downward pressing of the bushing 2000.

[0122] In some examples, optionally, the third connection portion 23 includes a socket 231, and the socket 231 is used for plugging and mating with the driving device.

[0123] The third connection part 23 may include the above-mentioned nut 232, and the nut 232 is provided with a plug hole 231. The third connection part 23 is designed to be plug-in, which has a simple structure and is easy to disassemble and assemble the second pair of locking members 20 and the driving device.

[0124] The socket 231 can be a circular hole, a polygonal hole or a special-shaped hole. The driving device is used to plug and cooperate with the socket 231, so the driving device has a connector that matches the socket 231 (such as the drill bit mentioned above), and the shape and size of the connector match the shape and size of the socket 231.

[0125] Furthermore, in order to enable the second pair of locking elements 20 to rotate after the connector is connected to the insertion hole 231 , the connector and the insertion hole 231 need to be positioned at the upper limit of the circumference of the insertion hole 231 .

[0126] Therefore, when the jack 231 is a circular hole, the side wall of the jack 231 needs to be provided with a keyway (not shown in the figure), and the connector is provided with a key (not shown in the figure) matching the keyway. When the jack 231 is a polygon or anisotropic, the keyway may not be provided, and the connector and the jack 231 can be directly limited and matched along the circumferential direction.

[0127] Combined with Figure 1-3 As shown, in some examples, optionally, the pressing portion 22 includes a pressing plate 221 circumferentially connected to the second connecting portion 21 , and a pressing surface 2211 matching the surface shape of the bushing 2000 is provided on the side of the pressing plate 221 facing the first pair of locking members 10 .

[0128] The material of the lower pressure plate 221 and the screw rod 211 can be the same or similar, for example, both are metal materials or plastics. The lower pressure plate 221 and the screw rod 211 can be connected and fixed by welding, snap connection, etc., or the two can be integrally formed during processing.

[0129] The lower pressure plate 221 has an annular structure, or is approximately annular. The upper surface of the lower pressure surface 2211 may be a plane, and at least a portion of the lower surface is the lower pressure surface 2211 .

[0130] The lower pressing surface 2211 matches the shape of the upper surface of the bushing 2000 , so that the lower pressing plate 221 can better fit the bushing 2000 , reducing the possibility of wear between the bushing 2000 and the lower pressing plate 221 during the pressing process.

[0131] The lower pressure plate 221 and the screw rod 211 may be fixedly connected so that they rotate synchronously, or the lower pressure plate 221 may be connected to the screw rod 211 via a bearing so that when the screw rod 211 rotates and descends, the lower pressure plate 221 does not rotate but only descends due to the friction force of the bushing 2000 .

[0132] In some examples, optionally, a limiting boss 2212 for extending into the bushing 2000 is provided in the middle of the lower pressing surface 2211 , and along the radial direction of the bushing 2000 , the size of the limiting boss 2212 is smaller than the size of the inner wall of the bushing 2000 .

[0133] The shape of the limiting boss 2212 can be a cylinder, a square column, etc. The shape of the limiting boss 2212 can match the shape of the inner wall surface of the bushing 2000. For example, the cross-sections of both are circular as shown in the figure.

[0134] When the pressing surface 2211 presses down the bushing 2000 , the limiting boss 2212 is located in the bushing 2000 . Since the size of the limiting boss 2212 is designed to be smaller than the size of the inner wall of the bushing 2000 , the limiting boss 2212 can be loosely matched with the inner wall of the bushing 2000 .

[0135] When radial displacement occurs when the bushing 2000 is pressed downward, the limiting boss 2212 of this embodiment can limit the bushing 2000 and perform radial limiting cooperation, thereby reducing the possibility of radial displacement during the pressing process of the bushing 2000.

[0136] In addition, the protruding height of the limiting boss 2212 of this embodiment needs to be such that it does not contact the above-mentioned connecting boss 112 during the process of the pressing portion 22 pressing down the bushing 2000, so as to reduce the possibility of the two impacting the pressing down of the bushing 2000 after the two are offset.

[0137] Combined with the attachment again Figure 1-3 As shown, in some examples, optionally, the bushing assembly tool 100 further includes a base 40 , and the first pair of locking elements 10 is mounted on the base 40 .

[0138] The base 40 may be provided with a receiving groove 41 that matches the shape and size of the second pair of locking elements 20 , and a portion of the second pair of locking elements 20 is installed in the receiving groove 41 , thereby achieving fixation of the second pair of locking elements 20 .

[0139] In order to facilitate the installation of the distance detecting member 30 , a second mounting hole 42 may be provided on the base 40 . The second mounting hole 42 may be a through hole penetrating the base 40 , so as to facilitate the insertion and extension of the distance detecting member 30 .

[0140] The base 40 may be made of metal, plastic or other materials with certain structural strength. The base 40 may be in the shape of a block as shown in the figure, or in other shapes such as a plate, which are not listed one by one in this embodiment.

[0141] In addition, an avoidance hole 43 for part of the screw 211 to extend into can be opened on the base 40. The avoidance hole 43 can be a through hole as shown in the figure, or it can be a blind hole. When the downward stroke of the bushing 2000 to be installed is too large, the avoidance hole 43 can allow the screw 211 to enter, so as to drive the lower pressure plate 221 to press down the bushing 2000.

[0142] like Figure 4 As shown, when the bushing assembly tool 100 of this embodiment is actually used, multiple first pairs of locking members 10 are installed one by one on multiple bases 40, and the multiple first pairs of locking members 10 are locked one by one with multiple second pairs of locking members 20 to install multiple bushings 2000 to the mounting structure 3000.

[0143] This embodiment uses the base 40 to place the first pair of locks 10, which improves the stability of the first pair of locks 10 during the rotation of the second pair of locks 20, thereby improving the stability of both during the installation of the bushing 2000 to the overload space.

[0144] In some examples, optionally, the base 40 is provided with a fourth connection portion 44 for docking with an external rack 200 .

[0145] The fourth connection part 44 and the frame 200 can be mechanically connected by bolt connection, plug-in connection, clamping connection or the like. When the base 40 is provided with the fourth connection part 44 to connect with the external frame 200, the frame 200 can be used to provide a working platform for the entire bushing assembly tooling 100.

[0146] The fourth connection portion 44 can be disposed on a side of the base 40 away from the first pair of locking elements 10 , or can be disposed at other positions. The specific location is determined according to the connection relationship between the fourth connection portion 44 and the body of the frame 200 .

[0147] In some examples, optionally, the fourth connecting portion 44 includes a connecting ear 441 and a connecting hole 442 opened in the connecting ear 441, and the connecting ear 441 is arranged on the side of the base 40 away from the first pair of locking elements 10, and extends from the base 40 along the first direction X, and the first direction X intersects with the arrangement direction from the first surface 11 to the second surface 12.

[0148] The connecting ears 441 may be located on one side or both sides of the base 40 along the first direction X. When the base 40 is used in a specific application, the first direction X may be a horizontal direction.

[0149] The connecting ear 441 and the base 40 may be integrally formed. The connecting ear 441 is provided with a connecting hole 442 . The connecting hole 442 may penetrate the connecting ear 441 along the arrangement direction from the first surface 11 to the second surface 12 .

[0150] When docking with the rack 200 outside, it can be connected to the rack 200 through the connection hole 442. The connection method can be plug-in, or the connection hole 442 and the rack 200 are docked by connecting parts such as bolts.

[0151] In this embodiment, the fourth connection portion 44 is designed to include a connection ear 441 and a connection hole 442 , and the connection hole 442 is used to connect to the external rack 200 , which has a simple structure and is easy to implement.

[0152] Combined with Figure 5-7 As shown, based on the above-mentioned bushing assembly tool 100, an embodiment of the present application provides a bushing assembly device 1000, including a frame 200, a limiting component 300 and a bushing assembly tool 100 as any one of the above-mentioned technical solutions, the limiting component 300 and the bushing assembly tool 100 are installed on the frame 200, and the limiting component 300 is used to limit the displacement of the mounting structure 3000 along the first direction X and the second direction Y. The first direction X and the second direction Y intersect, and intersect at the arrangement direction from the first surface 11 to the second surface 12 respectively.

[0154] The bottom of the rack 200 may also be provided with a walking structure such as a walking wheel 250 to facilitate operators to move the rack 200 .

[0155] The limiting assembly 300 can be installed on the mounting plate 240 of the second support frame 230. The limiting assembly 300 can be supported by the mounting structure 3000 with the second pair of locks 20. The limiting assembly 300 is also used to limit the displacement of the mounting structure 3000 along the first direction X and the second direction Y.

[0156] In some embodiments, the first direction X and the second direction Y may both be horizontal directions, both intersecting or even perpendicular to the third direction Z, the third direction Z being the arrangement direction from the first surface 11 to the second surface 12, and the third direction Z may be a vertical direction in some embodiments.

[0157] In this embodiment, the frame 200 is used to provide a platform for the bushing 2000 assembly operation, and the position of the mounting structure 3000 is limited by the limiting assembly 300, thereby improving the stability of the mounting structure 3000 during the bushing 2000 assembly process.

[0158] In some examples, optionally, the limiting assembly 300 includes a plurality of limiting members 310 , which are arranged at intervals around the top of the rack 200 and are used to abut against the mounting structure 3000 .

[0160] The mounting structure 3000 abuts against the plurality of limiting members 310 to achieve the bearing of the mounting structure 3000 and the limiting of the mounting structure 3000 along the first direction X2 and the second direction Y.

[0161] In this embodiment, the limiting assembly 300 is designed to include a plurality of limiting members 310 , and the displacement of the mounting structure 3000 is limited by the abutment between the plurality of limiting members 310 and the mounting structure 3000 .

[0162] The limiting member 310 may be in a block shape as shown in the figure, and may also be in a rod shape, a plate shape, etc., which are not listed one by one in this embodiment.

[0163] In addition, the structure of the limiting assembly 300 of this embodiment is not limited to a plurality of limiting members 310, but may also be an integral limiting frame.

[0164] In addition, the position of the position-limiting member 310 of this embodiment on the mounting plate 240 can be adjusted along the first direction X or the second direction Y to match the mounting structures 3000 of different specifications. The specific adjustment method of the position-limiting member 310 on the mounting plate 240 can be to connect the position-limiting member 310 to the connection structure at different positions on the mounting plate 240, and the connection structure can be a hole, a groove or a rod, etc.

[0166] This embodiment utilizes a limiting bottom wall 3111 of a plurality of limiting grooves 311 to support the mounting structure 3000, and the limiting side walls 3112 abut against the side edges of the mounting structure 3000, which not only facilitates the installation and removal of the mounting structure 3000, but also provides a good limiting and fixing effect for the mounting structure 3000.

[0167] The limiting member 310 can be in various forms, combined with the attached Figure 6 The limiting member 310 shown has two limiting side walls 3112 and a limiting bottom wall 3111.
