[0046] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] First embodiment

[0048] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a backlight module, including a backplate 5 and a mainboard assembly. The backplate 5 is provided with a mating shell 1, and the mating shell 1 is provided with a positioning member 11 and a stopper 12. The mating shell 1 has an opening 13 along a first direction. The mainboard assembly includes a mainboard 6 and a mounting member 2 provided on the mainboard 6. The mounting member 2 is provided with a buckle 3 and a stopper 4 on both sides along the first direction. The stopper 4 is movably provided on the mounting member 2. The mainboard assembly also includes a mounting opening 21 that cooperates with the positioning member 11. The two side walls of the mounting opening 21 in the second direction abut against the positioning member 11.

[0049] In the connected state, the buckle 3 extends into the mating shell 1 through the opening 13, and the side of the anti-slip platform 12 away from the opening 13 abuts against the anti-slip part 4, and the mating shell 1 abuts against the anti-slip part 4 and the buckle 3 on both sides of the third direction respectively; the first direction, the second direction and the third direction intersect.

[0050] In the connected state, the mating shell 1 abuts against the buckle 3 and the retaining member 4 on the mounting member 2 on both sides in the first direction to achieve position limitation in the first direction; the positioning member 11 on the mating shell 1 abuts against the mounting opening 21 on the mounting member 2 on both sides in the second direction to achieve position limitation in the second direction; and the mating shell 1 abuts against the buckle 3 and the retaining member 4 on both sides in the third direction to achieve position limitation in the third direction. This connection method achieves a detachable connection between the mounting member 2 and the mating shell 1, and also ensures the tightness and reliability of the connection between the mounting member 2 and the mating shell 1, preventing loosening.

[0051] The buckle 3 on the mounting part 2 extends into the interior of the mating shell 1, and the anti-slip platform 12 cooperates with the anti-slip part 4 to stably connect the back panel 5 and the main board 6, while also effectively preventing the back panel 5 and the main board 6 from loosening.

[0052] Reference Figure 2 and Figure 3In some embodiments, the anti-slip member 4 is movably provided on the mounting member 2, including a driving member provided on the mounting member 2, and the output end of the driving member is connected to the anti-slip member 4 to realize the movement of the anti-slip member 4 on the mounting member 2. Different driving members can be selected according to the movement trajectory of the anti-slip member 4. Exemplarily, the anti-slip member 4 includes movement on the mounting member 2 in a straight line direction, and the driving member may include a cylinder, a hydraulic cylinder or an electric push rod. The anti-slip member 4 includes rotation on the mounting member 2, and the driving member includes a motor. Under the driving force of the driving member, the position of the anti-slip member 4 will not affect the installation during the initial installation process; and in the final installation process, the position of the anti-slip member 4 is moved to achieve a stable connection of the mounting member 2 to the mating shell 1.

[0053] In some application scenarios, the space for connection and mating is small, making it difficult to install the driver. In some optional embodiments, the anti-slip member 4 is an elastic member that uses its own elastic properties to achieve positional movement within a certain range, thereby ensuring the anti-slip effect of the connection. It should be noted that the elastic member described in this embodiment includes structures similar to springs and shrapnel with large elastic deformation, and also includes components similar to metal materials with small elastic deformation.

[0054] Reference Figure 2 and Figure 3 In some embodiments, the retaining member 4 includes a first retaining portion 41 and a second retaining portion 42. One end of the first retaining portion 41 is connected to the mounting member 2, and the other end of the first retaining portion 41 is inclined toward the mating shell 1. In the connected state, the other end of the first retaining portion 41 abuts against the outer wall of the mating shell 1. The second retaining portion 42 is connected to the side of the first retaining portion 41 away from the mounting member 2. The second retaining portion 42 extends along the third direction. The side of the second retaining portion 42 away from the first retaining portion 41 is used to abut against the side wall of the retaining platform 12 away from the opening 13. With the arrangement of the first retaining portion 41 and the second retaining portion 42, in the installed state, the retaining member 4 can simultaneously limit the mating shell 1 on one side in the first direction and on one side in the third direction.

[0055] When disassembly is required, the anti-slip member 4 is moved along the third direction toward the side away from the mating shell 1 to simultaneously release the limitation of the mounting member 2 on the mating shell 1 in the first direction and the third direction, which is also convenient for the technicians to operate and improves the work efficiency of installation and disassembly.

[0056] In some embodiments, in the third direction, the height of the second anti-slip portion 42 is greater than the height of the side wall of the anti-slip platform 12 away from the opening 13, so that in the connected state, at least a portion of the second anti-slip portion 42 can protrude from the anti-slip platform 12, so that technicians can apply force to the protruding portion of the second anti-slip portion 42 to achieve the movement of the anti-slip component 4 in the third direction for easy disassembly.

[0057] Combine Figure 8 and Figure 9 Optionally, a handle portion 43 is provided on the second anti-detachment portion 42. The setting of the handle portion 43 provides a position for technicians to apply force, thereby improving the disassembly efficiency. Specifically, the handle portion 43 is provided at the end of the second anti-detachment portion 42 away from the first anti-detachment portion 41. The specific structure of the handle portion 43 is not limited in this embodiment. For example, the middle position of the handle portion 43 is connected to the second anti-detachment portion 42; or the end of the handle portion 43 in the first direction is connected to the second anti-detachment portion 42. In this case, the handle portion 43 can be extended toward the side close to the buckle 3, or the handle portion 43 can be provided toward the side away from the buckle 3.

[0058] See also Figure 2 and Figure 6 In some embodiments, the cross-section of the anti-slip platform 12 perpendicular to the second direction is a right triangle, and the side of the anti-slip platform 12 that fits with the matching shell 1 is one of the right-angled sides of the right triangle, and the side of the anti-slip platform 12 that fits with the second anti-slip portion 42 is the other right-angled side of the right triangle; thereby ensuring a stable connection between the anti-slip platform 12 and the mounting member 2, and maximizing the fitting area between the anti-slip platform 12 and the second anti-slip portion 42, thereby ensuring a limiting effect. In addition, the inclined surface of the right triangle of the anti-slip platform 12 can also guide the anti-slip component 4 during connection. Under the elastic force of the anti-slip component 4, the anti-slip platform 12 and the anti-slip component 4 can automatically fit together during connection to achieve an anti-slip effect after connection.

[0059] Optionally, the back panel 5 is integrally stamped to form a mating shell 1 , the opening 13 of the mating shell 1 is used to engage with the buckle 3 on the main board 6 , and the anti-slip platform 12 on the mating shell 1 is used to cooperate with the anti-slip part 4 on the main board 6 to lock the buckle 3 .

[0060] See also Figure 2 and Figure 4In some optional embodiments, the mounting member 2 is provided with an operating opening 23 in the third direction, and the operating opening 23 extends along the first direction. The operating opening 23 is opened in the middle position of the mounting member 2, and the first anti-slip portion 41 of the anti-slip member 4 is connected to the wall surface of the operating opening 23, and the entire anti-slip member 4 is located in the operating opening 23. Through this arrangement, the compactness and smallness of the overall structure of the device are achieved, and the overall size of the mounting member 2 is reduced.

[0061] Reference Figure 11 and Figure 12 Similarly, the end of the first retaining portion 41 of the retaining member 4, which is away from the second retaining portion 42, can also be connected to the end of the mounting member 2 in the first direction. In this case, the first retaining portion 41 includes an inclined portion, a flat portion, and a connecting portion, wherein the inclined portion is used to connect to the second retaining portion 42, the flat portion is located above the mounting member 2, and the connecting portion is used to connect to the end of the mounting member 2; this connection method ensures the elastic effect of the retaining member 4.

[0062] Combine Figure 1 Optionally, the length of the operating opening 23 in the first direction is greater than the length of the retaining member 4 in the first direction. Due to its own elastic properties, the retaining member 4 can rotate around the connection position between itself and the mounting member 2 as the center of a circle. By setting the operating opening 23 to be longer, the rotation operation of the retaining member 4 is facilitated, thereby facilitating the connection and removal between the mounting member 2 and the mating shell 1.

[0063] Reference Figure 4-Figure 6 In some embodiments, the mounting opening 21 extends along the first direction, and the mounting opening 21 is formed through the mainboard 6 along the third direction, or the mounting opening 21 is formed through the mounting member 2 along the third direction. By configuring the mounting opening 21 as an extended slot, the positioning member 11 can be inserted into the mounting opening 21 during the initial installation phase to limit the mainboard assembly relative to the mating shell 1 in the second direction, thereby improving installation and positioning efficiency. Furthermore, during installation, the clip 3 is inserted into the interior of the mating shell 1 through the opening 13 to achieve connection with the clip 3. Since the mounting opening 21 extends along the first direction, the positioning member 11 can move synchronously within the mounting opening 21 during the extension of the clip 3, thereby avoiding motion interference.

[0064] See also Figure 2 and Figure 4Specifically, when the mounting opening 21 is formed on the mounting member 2, the mounting opening 21 and the operating opening 23 are spaced apart in the first direction, or the mounting opening 21 and the operating opening 23 are spaced apart in the second direction. Optionally, the mounting opening 21 and the operating opening 23 are spaced apart in the first direction. When the size of the mounting member 2 is constant, the length of the operating opening 23 in the second direction is maximized to facilitate operation of the retaining member 4.

[0065] Optionally, the end of the mounting opening 21 facing the operating opening 23 is connected to the operating opening 23, thereby providing a larger space for the positioning member 11. Although the positioning member 11 is a raised component provided on the outside of the mating shell 1, its influence and interference during the connection process can be reduced. In addition, with this arrangement, the positioning member 11 occupies less area of ​​the mainboard 6 within the mounting member 2, which can reduce the size of the mainboard 6 and save costs.

[0066] Reference Figure 10 and Figure 11 Similarly, when the mounting opening 21 is opened on the main board 6, the mounting opening 21 and the mounting member 2 are spaced apart in the first direction, or the mounting opening 21 and the mounting member 2 are spaced apart in the second direction.

[0067] See also Figure 2 、 Figure 3 and Figure 12 In some embodiments, the buckle 3 includes a first clamping portion 31, a second clamping portion 32, and a third clamping portion 33, wherein the first clamping portion 31 is bent and connected to the mounting member 2, including the first clamping portion 31 connected to one end of the mounting member 2 in the first direction; in addition, the first clamping portion 31 is also connected to the wall surface of the operating port 23. In the connected state, the first clamping portion 31 abuts against the end of the opening 13. The second clamping portion 32 is connected to the side of the first clamping portion 31 away from the mounting member 2, and the second clamping portion 32 is used to extend into the mating shell 1. The third clamping portion 33 is connected to the side of the second clamping portion 32 away from the first clamping portion 31, and the third clamping portion 33 is inclined toward the side away from the mounting member 2. The provision of the third clamping portion 33 facilitates the insertion of the buckle 3 into the opening 13, thereby achieving quick connection and improving connection efficiency.

[0068] See also Figure 3-Figure 7 The first latch portion 31 is connected to the mounting member 2 and is bent so that the side of the first latch portion 31 facing the opening 13 can abut against the end of the opening 13 when installed, thereby limiting the position in the first direction. The second latch portion 32 and the third latch portion 33 are configured to extend into the interior of the mating housing 1 to abut against the inner wall surface of the mating housing 1 in the third direction, thereby limiting the position in the third direction.

[0069] See also Figure 2 Specifically, the opening 13 of the mating shell 1 is formed by extending a certain depth along the third direction from one end of the mating shell 1 in the first direction. Therefore, the opening 13 is L-shaped based on a cross-section perpendicular to the second direction. The remaining portion of the opening 13 in the third direction of the mating shell 1 enhances the connection strength between the mating shell 1 and the positioning member 11.

[0070] Combine Figure 7 Optionally, the first clamping portion 31 is a structure extending along the third direction, so that in the connected state, the side of the first clamping portion 31 facing the opening 13 can be completely fitted with the end face of the opening 13, thereby ensuring the connection effect and avoiding loosening or shaking after connection.

[0071] Optionally, the second latch portion 32 is a structure extending along the first direction, and the end of the second latch portion 32 away from the first latch portion 31 is inclined toward the side closer to the mounting member 2. The third latch portion 33 is connected to the end of the second latch portion 32 away from the first latch portion 31, and the end of the third latch portion 33 away from the second latch portion 32 is inclined toward the side farther from the mounting member 2. The overall bent shape of the second and third latch portions 32 and 33 facilitates the insertion of the third latch portion 33 into the interior of the mating shell 1 through the opening 13.

[0072] In some embodiments, the buckle 3 and the anti-slip member 4 are integrally formed on the mounting member 2 to ensure the overall connection strength of the mounting member 2.

[0073] See also Figure 3 and Figure 4 Optionally, a connection chamfer 34 is provided at the connection between the buckle 3 and the mounting member 2. The connection chamfer 34 can improve the bending strength of the buckle 3 during connection and disassembly, thereby increasing the service life of the mounting member 2.

[0074] See also Figure 1 and Figure 2 In some embodiments, the mainboard 6 is provided with mounting holes 61 extending along the third direction, and the mounting member 2 is provided with pins 22 that plug into and mate with the mounting holes 61. By plugging the pins 22 into the mounting holes 61, the mounting member 2 is connected to the mainboard 6. After the mounting member 2 is connected to the mating housing 1, the mainboard 6 is connected to the backplane 5.

[0075] Optionally, in order to ensure the reliability of the connection, the pin 22 is fixed in the mounting hole 61. Optionally, the pin 22 can be fixed in the mounting hole 61 by welding or bonding to ensure the stability of the connection between the mounting part 2 and the mainboard 6.

[0076] Optionally, the mounting member 2 is provided with pins 22 at each corner, and the mainboard 6 is provided with a plurality of mounting holes 61 corresponding to the pins 22. The dimensions of at least one pin 22 are different from those of the other pins 22, where the dimensions of the pin 22 are the length of the pin 22 in the first direction and / or the second direction. By providing different dimensions for the pins 22, the mounting member 2 can be accurately installed on the mainboard 6, preventing the mounting member 2 from being installed upside down.

[0077] In some embodiments, the cross section of the pin 22 perpendicular to the second direction may be rectangular or other polygonal shapes, such as a step shape, a convex shape, or a triangular shape.

[0078] In some embodiments, the mainboard 6 is provided with a connection position 62 along the third direction, and the connection position 62 is adapted to the mounting member 2. After the pin 22 is inserted into the mounting hole 61, the mounting member 2 is located in the connection position 62, making the overall structure more compact and preventing the mounting member 2 from protruding from the mainboard 6 and interfering with the interaction between the mainboard 6 and other components.

[0079] Specifically, the mounting member 2 and the mainboard 6 are wave soldered or reflow soldered, and the solder cools and solidifies to solder the pins 22 to the mounting holes 61, so that the mainboard 6 can be quickly installed on the backplane 5 through the buckle 3, thereby improving production efficiency and reducing materials on the production end.

[0080] Reference Figure 2-Figure 7 When connection is required, the main board 6 is moved in the positive direction of the first direction (i.e. the right side in the figure) so that the third clamping portion 33 of the buckle 3 extends into the mating shell 1 through the opening 13. At the same time, the positioning member 11 is embedded in the mounting opening 21, and the main board 6 continues to move until the second clamping portion 32 of the buckle 3 is fully extended into the mating shell 1. In this process, the connection between the first locking portion 41 and the second locking portion 42 of the locking member 4 abuts against the upper surface of the mating shell 1, and gradually moves to abut against the oblique edge of the locking platform 12 as the main board 6 moves, until the main board 6 moves to the second locking portion 32 of the buckle 3 is fully extended into the mating shell 1, the connection between the first locking portion 41 and the second locking portion 42 abuts against the upper surface of the mating shell 1, and the second locking portion 42 abuts against the right-angled edge of the locking platform 12, thereby realizing the mutual cooperation between the locking member 4 and the locking platform 12 to ensure the reliability of the connection of the main board 6 to the backplane 5 and prevent the main board 6 from falling off.

[0081] Reference Figure 3 、 Figure 8 、 Figure 9When disassembly is required, the handle portion 43 of the retaining member 4 is pulled upward so that the height of the first retaining portion 41 and the second retaining portion 42 is higher than the height of the retaining platform 12. The retaining member 4 is then pulled in the negative direction of the first direction (i.e., the left side in the figure) until the buckle 3 is withdrawn from the mating shell 1 through the opening 13. This allows the motherboard 6 to be removed from the back plate 5. During both installation and removal, no force is required to be applied to the motherboard 6, which can also prevent damage to the motherboard 6.

[0082] In summary, in this embodiment, the mainboard 6 is fixed and locked to the backboard 5 by the buckle 3. Compared with the screw fixing method used in the prior art, the use of the buckle 3 can improve production and assembly efficiency and reduce production-end materials. The provision of the anti-slip member 4 and the anti-slip platform 12 can effectively prevent the mainboard 6 from falling off. At the same time, the positioning member 11 and the anti-slip platform 12 on the mating shell 1 are compact in structure, making the overall size of the mating shell 1 small, thereby ensuring the production yield of the backboard 5, and also avoiding the problem of interference between the mating shell 1 and the pins 22.

[0083] Reference Figure 13 and Figure 14 In some embodiments, the motherboard 6 is configured as a rectangular parallelepiped. Two mounting members 2 are provided on the motherboard 6. Correspondingly, two mating shells 1 are provided on the backplane 5. The two mating shells 1 correspond to the two mounting members 2 for connection. Optionally, the two mounting members 2 are provided at diagonal positions on the motherboard 6 to ensure stable connection to the motherboard 6.

[0084] To further ensure the connection stability of motherboard 6, the rectangular parallelepiped structure of motherboard 6 has four corners, which can be divided into two groups of diagonal structures. Mounting members 2 are provided at both corners of one group of diagonal structures. The other group of diagonal structures of motherboard 6 is connected to backplate 5 via a connecting assembly 7. Connecting assembly 7 includes a mating connecting shell 74 disposed on backplate 5, with a connecting opening 73 defined therein. The orientation of connecting opening 73 is the same as that of opening 13. Connecting assembly 7 also includes a mounting connector 71 disposed on motherboard 6, with a connecting clip 72 configured to extend into opening 73. Inserting connecting clip 72 into mating connecting shell 74 establishes the connection between motherboard 6 and backplate 5. By aligning opening 73 with opening 13, when clip 3 is moved into opening 13, connecting clip 72 also moves into opening 73, achieving a mating connection and improving installation efficiency.

[0085] Specifically, the installation connector 71 is provided with connecting pins on both sides of the second direction, and the connecting pins are extended along the third direction.
