[0040] Please see Figures 1-8 This embodiment provides a pressing device, including a pressing component 100 and a support component 200. The support component 200 has a receiving groove 2021 for supporting a circuit board 3. More specifically, one end of the circuit board 3 extends into the receiving groove 2021 to realize the support component 200 supporting and pre-fixing the circuit board 3.

[0041] The pressing assembly 100 and the bearing assembly 200 are arranged opposite to each other, such as Figure 1 , Figure 3 As shown, the pressing assembly 100 includes: a pressure plate 101 and a guide member 102. The guide member 102 is fixed to the pressure plate 101 and is disposed on the side of the pressure plate 101 facing the support assembly 200. The guide member 102 abuts against one end of the circuit board 3 for guiding the circuit board 3 during installation. The other end of the circuit board 3 is received in the receiving groove 2021. In this embodiment, both the pressing assembly 100 and the support assembly 200 are integrally formed, as shown... Figure 7 , Figure 8 As shown, after one end of the circuit board 3 is pressed into the receiving groove 2021 to achieve pre-fixation, the other end of the circuit board 3 faces the guide member 102. The user roughly aligns the other end of the circuit board 3 with the guide member 102, and by pressing the pressure plate 101, under the guiding action of the guide member 102, the other end of the circuit board 3 is tightly attached to the pressing assembly 100, thereby completing the secondary fixation of the circuit board 3.

[0042] Please see Figure 5 , Figure 6The supporting component 200 includes a base plate 201 and a side plate 202. The side plate 202 is mounted on the base plate 201. Part of the side plate 202 is hollow to form a receiving groove 2021. The side plate 202 may include an upper clamping plate and a lower clamping plate. A gap is reserved between the upper clamping plate and the lower clamping plate, which forms the receiving groove 2021 to support the circuit board 3.

[0043] In some preferred embodiments, the carrier component 200 further includes: a first fixing component, such as Figure 5 , Figure 6 As shown, the first fixing component includes a limiting plate 203, a first fixing plate 204, and the other end of the circuit board housed in the receiving groove 2041. The limiting plate 203 is fixed to the side plate 202, the first fixing plate 204 is connected to the side plate 202, and the first fixing groove 2041 is formed in the first fixing plate 204. The limiting plate 203 can be a vertical plate fixed to one end of the side plate 202. When one end of the circuit board 3 is pressed into the receiving groove 2021, at least a portion of the circuit board 3 remains outside the receiving groove 2021, near the side of the pressing component 100. At this time, during the process of the user pressing the pressure plate 101, the guide 102 will move towards the limiting plate 203. When the guide 102 contacts the limiting plate 203, under the limiting action of the limiting plate 203, the guide 102 will no longer move, avoiding damage to the circuit board 3 due to excessive pressing of the guide 102, thereby achieving precise secondary fixing of the circuit board 3. Figure 6 As shown, the first fixing plate 204 is U-shaped. The first fixing plate 204 may include a left clamping plate, a base plate and a right clamping plate. The left clamping plate is fixed to the first fixing plate 204. The base plate and the right clamping plate are both fixed to the left clamping plate and extend outward from one side of the left clamping plate. A first fixing groove 2041 is formed between the left clamping plate, the base plate and the right clamping plate. The first fixing groove 2041 can accommodate the second fixing plate 103, thereby realizing the fixing of the bearing component 200 and the pressing component 100.

[0044] In some preferred embodiments, the support component 200 and the pressing component 100 are integrally formed. Users can configure multiple sets of receiving slots 2021 and guide members 102 according to actual needs. Compared with screw-locking installation, multiple circuit boards 3 can be installed by simply guiding and fixing them once through the guide member 102. The support component 200 also includes a second fixing component 205 and a second fixing slot 2051, such as... Figure 6As shown, the second fixing component 205 is fixed to the base plate 201, and the second fixing groove 2051 is formed in the second fixing component 205. Specifically, the second fixing component 205 is located inside the side plate 202. The second fixing component 205 includes a base fixed to the base plate 201. The second fixing groove 2051 extends from the base and faces the side close to the pressing component 100. The second fixing groove 2051 can be a notch opened on the upper surface of the base. The orientation of the second fixing groove 2051 is consistent with the direction of the plane where the receiving groove 2021 is located. During the process of pressing the circuit board 3 into the receiving groove 2021, part of it is fixed to the base plate 201 through the second fixing groove 2051 to further tighten the circuit board 3.

[0045] Preferably, the guide member 102 includes a guide plate 1021 and a guide groove 1022. Please refer to [link / reference]. Figure 3 , Figure 4 The guide plate 1021 is fixed to the pressure plate 101, and the guide groove 1022 is formed on the guide plate 1021, located on the inner side of the guide plate 1021 facing the pressure plate 101. There are multiple sets of guide plates 1021, each set of guide plates having one guide groove, and every two sets of guide plates are used to guide and fix one circuit board 3. In this embodiment, there are four sets of guide plates 1021, and correspondingly, there are also four sets of guide grooves 1022. Every two guide grooves 1022 are arranged facing each other. The position of the guide groove 1022 on the guide member 102 corresponds to the position of the receiving groove 2021 on the bearing assembly 200, thereby achieving the purpose of accurate secondary fixing by quickly guiding the other end of the circuit board 3 after the circuit board 3 is pre-fixed.

[0046] In this embodiment, the pressing assembly 100 further includes a second fixing plate 103, which is fixed to the pressure plate 101. The second fixing plate 103 and the guide member 102 are located on the same side of the pressure plate 101. More specifically, the second fixing plate 103 and the guide member 102 are both located on the side of the pressure plate 101 facing the supporting assembly 200. Figure 3 , Figure 5 As shown, there are two second fixing plates 3, which are fixed on the outer side of the pressure plate 101 respectively. The shape of the second fixing plate 3 is adapted to the first fixing groove 2041, ensuring that the second fixing plate 3 can be accurately pressed into the corresponding first fixing groove 2041 to achieve the fixing of the pressing component 100 and the bearing component 200.

[0047] To make more efficient use of the limited space inside the lamp, the number of receiving slots 2021 is at least two, and the number of guide members 102 is at least two. In this embodiment, the number of receiving slots 2021 and the number of guide members 102 are two, which can be used for the installation of two circuit boards 3. Each guide member 102 includes two guide slots 1022 to achieve a correspondence with the number of receiving slots 2021. Those skilled in the art will understand that the number of receiving slots 2021 and guide members 102 can also be three or more, which is not limited here. Since the pressure plate 101 and the base plate 201 are shared, it is only necessary to add a corresponding number of receiving slots 2021 and guide members 102 to the above-mentioned shared plate. The more circuit boards 3 there are, the lower the cost of using the pressing device of the present invention.

[0048] Preferably, the gap between the guide groove 1022 and the circuit board 3 is 0.05 to 0.2 mm. In this embodiment, the gap between the guide groove 1022 and the circuit board 3 is 0.1 mm, which facilitates the precise pressing of the circuit board 3. After the circuit board 3 is installed in the guide groove 1022, it will not easily loosen, thus ensuring the installation accuracy of the pressing device.

[0049] The working principle of the pressing device of the present invention is roughly as follows: First, a gasket 4 is attached to the surface of each circuit board 3 to achieve electrical insulation between each circuit board 3. One end of the circuit board 3 is pressed into the receiving groove 2021 to achieve pre-fixation. During this process, a part of the circuit board 3 will be fixed to the base plate 201 through the second fixing groove 2051 to achieve further tightening of the circuit board 3.

[0050] After pre-fixing, at least a portion of the circuit board 3 is located outside the receiving groove 2021, near the side of the pressing assembly 100. At this time, the user can roughly align the circuit board 3 with the guide groove 1022 and press the pressure plate 101. During this process, the guide 102 will move towards the limiting plate 203. When the guide 102 contacts the limiting plate 203, the guide 102 will no longer move under the limiting action of the limiting plate 203, thereby achieving precise secondary fixing of the circuit board 3.

[0051] This invention utilizes a receiving groove on the supporting component to support the circuit board, achieving pre-fixation at one end of the circuit board. A guide component corresponding to the supporting component guides the circuit board for secondary fixation, eliminating the need for screw tightening and simplifying the installation process. Since the pressing component and the supporting component are integrally molded, multiple sets of receiving grooves and guide components can be configured according to actual needs. Compared to screw-locking installation, users only need to guide and fix the circuit board once using the guide component to install multiple circuit boards, significantly saving time and costs. The first and second fixing plates work together to fix the pressing component and the supporting component, resulting in high stability and good shock resistance of the pressing device.

[0052] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
