For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0053] According to one embodiment of the present application, referring to Figure 1 , Figure 3-Figure 8 As shown, the phototherapy device of the present application includes a control box 1, a substrate 2, a light strip 3 and a light-transmitting member 4. The processing method of the phototherapy device provided by the present application includes the following steps S101 to S106.
[0054] S101, assembling the control box 1.
[0055] The control box 1 is the control component of the entire phototherapy device, responsible for power management, control operation and other functions. It needs to be assembled first to ensure that it can be smoothly connected with other components in the subsequent steps.
[0056] S102 , placing the control box 1 in a first injection mold, and injection-molding the substrate 2 in the first injection mold, so as to construct a base 5 on one side of the substrate 2 that is injection-molded and wrapped around the control box 1 , and to construct a receiving groove 6 on the other side of the substrate 2 .
[0057] The substrate 2 is manufactured by injection molding, which can ensure the integration of parts, reduce seams, and thus improve waterproof performance. It not only serves as a basic platform for carrying other components, but also forms different functional areas on both sides. One side is a base 5 for connecting with the control box 1; the other side is a receiving groove 6 for installing the light strip 3. The control box 1 and the light strip 3 are arranged on both sides of the substrate 2, which can ensure that the electronic components inside the control box 1 are away from the heat generated by the light strip 3, thereby improving the stability and life of the device. In addition, the substrate 2 can be a silicone pad to improve the user experience.
[0058] S103, separating the substrate 2 that has been injection-molded to wrap the control box 1 from the first injection mold.
[0059] When the substrate 2 of the control box 1 is cooled and hardened after being injection-molded, it is taken out from the first injection mold to facilitate subsequent operations.
[0060] S104 , installing the light strip 3 in the receiving groove 6 of the substrate 2 , and electrically connecting the light strip 3 to the control box 1 .
[0061] The light strip 3 is a key component for realizing phototherapy and is installed in the receiving groove 6 of the substrate 2. The light strip 3 can be composed of LED lights and can emit light of a specific wavelength for beauty and skin care purposes; and the light strip 3 needs to be electrically connected to the control box 1, which is a key step in realizing the phototherapy function. The control box 1 can control the working state of the light strip 3, such as turning it on, off or adjusting the light intensity.
[0062] S105. Place the substrate 2 with the light strip 3 installed in the second injection mold, control the upper mold of the second injection mold to sink a preset distance into the receiving groove 6, and control the injection molding machine to inject the light-transmitting material into the receiving groove 6 through the injection channel of the upper mold to form the light-transmitting component 4 that fixes and seals the light strip 3, thereby obtaining a phototherapy device.
[0063] The light-transmitting material for preparing the light-transmitting member 4 can be transparent silicone, polymethyl methacrylate, polycarbonate, etc. For example, the light-transmitting member 4 is made of transparent silicone, which is a material with good light transmittance, and also has good flexibility and temperature resistance. In order to prevent the transparent silicone from overflowing during the injection molding process, the upper mold of the second injection mold can be controlled to slightly sink by a preset distance of 0.02mm-0.5mm (for example, 0.1mm) during the injection molding process, so as to enter the receiving groove 6 of the substrate 2, so that the outer surface of the light-transmitting member 4 after molding is 0.02mm-0.5mm lower than the notch of the receiving groove 6. Optionally, the distance can be 0.1mm, 0.2mm or 0.3mm, etc. This method can effectively control the flow range of silicone, ensure that it is only filled in the predetermined space, and avoid excess material overflowing outside the receiving groove 6.
[0064] In this way, it can be ensured that the edge of the light-transmitting member 4 is substantially flush with the surface of the substrate 2 after injection molding, which not only helps to enhance the overall aesthetics of the device, but also reduces the possibility of dust and other impurities accumulating on the edge of the device, thereby improving the user experience.
[0065] It can be understood that the sinking injection molding technology can better control the filling amount and shape of the silicone, so that there is no obvious seam or gap between the light-transmitting member 4 and the groove wall of the receiving groove 6 of the substrate 2, and the product surface is smoother, thereby achieving a better sealing effect, reducing the risk of external pollutants or moisture entering the interior of the device, and also helping to improve the appearance quality of the product.
[0066] The light-transmitting member 4 fixes and seals the light strip 3 through an injection molding process, ensuring that light can be evenly distributed and preventing external moisture from entering, which not only protects the light strip 3 but also improves the sealing performance of the entire device.
[0067] Furthermore, since the control box 1 and the light-transmitting member 4 are connected to the substrate 2 by injection molding, the alignment and fixing steps in the subsequent assembly steps are omitted, the production process is simplified, and the assembly difficulty and cost are reduced. In addition, the control box 1 and the light-transmitting member 4 are tightly combined with the substrate 2 after injection molding, and are not easy to fall off or be damaged, which increases the durability of the device.
[0068] S106, separating the phototherapy device from the second injection mold.
[0069] When the light-transmitting material cools and hardens, the finished product is taken out of the mold to obtain a complete light therapy device.
[0070] Therefore, the processing method of the phototherapy device provided in the embodiment of the present application effectively solves the problems of poor sealing and waterproofing, safety hazards and poor appearance quality of the traditional phototherapy device through two injection molding processes. The phototherapy device produced in this way is more compact, more reliable and more beautiful.
[0071] According to one embodiment of the present application, the bottom of the upper mold of the second injection mold is provided with a boss matched with the receiving groove 6 of the substrate 2 and a crimping edge surrounding the boss, and the boss is provided with an injection channel.
[0072] The steps of placing the substrate 2 with the light strip 3 installed in the second injection mold, controlling the upper mold of the second injection mold to sink a preset distance into the receiving groove 6, and controlling the injection molding machine to inject the light-transmitting material into the receiving groove 6 through the injection channel of the upper mold include:
[0073] Place the substrate 2 on the lower mold of the second injection mold, and then control the upper mold to sink a preset distance so that the boss enters the receiving groove 6, and the crimping edge is pressed on the edge of the receiving groove 6 of the substrate 2, and control the injection molding machine to inject the light-transmitting material into the receiving groove 6 through the injection channel of the boss.
[0074] In this embodiment of the present application, a boss is designed at the bottom of the upper mold of the second injection mold, and the shape of the boss matches the receiving groove 6 on the substrate 2. The boss has a circle of crimping edges around it, which plays a sealing role during the injection molding process. The boss is provided with an injection channel for injecting light-transmitting material into the receiving groove 6.
[0075] Specifically, the substrate 2 with the light strip 3 is first placed on the lower mold of the second injection mold, and the substrate 2 is in an open state. Then, the upper mold is controlled to sink a preset distance until the boss accurately enters the receiving groove 6 of the substrate 2, and the crimping edge is tightly pressed on the edge of the receiving groove 6 of the substrate 2 to form a close contact surface.
[0076] After the upper mold sinks into place, the injection molding machine injects the light-transmitting material into the receiving groove 6 through the injection channel on the boss. Due to the existence of the crimping edge, it can apply a certain pressure to the edge of the substrate 2 during the injection molding process, which helps to maintain the flatness of the edge of the receiving groove 6 and prevent the light-transmitting material from overflowing out of the receiving groove 6 under high pressure.
[0077] In this way, not only is it ensured that the light strip 3 is effectively encapsulated in the light-transmitting material, but also the overflow of excess material is avoided, which is crucial for improving the sealing and waterproof performance of the product.
[0078] Moreover, since there is no excess material overflow, it means that the appearance of the product is neater, without any extra burrs or irregular shapes, which directly improves the appearance quality of the product.
[0079] Therefore, the embodiment of the present application can significantly reduce the product failure rate caused by material overflow through this precisely controlled injection molding method, thereby reducing the cost and time of subsequent processing.
[0080] According to one embodiment of the present application, when the injection molding machine is controlled to inject the light-transmitting material, the injection pressure of the injection molding machine is equal to the pressure applied by the crimping edge of the upper mold on the substrate 2 .
[0081] Specifically, when the pressure of the injection molding machine is equal to the pressure of the crimping edge, it can be ensured that during the injection molding process, the light-transmitting material is evenly filled in the receiving groove 6 without causing problems such as uneven material flow or bubbles due to pressure difference.
[0082] It is understandable that the role of the crimping edge is to prevent the light-transmitting material from overflowing out of the receiving groove 6. If the injection pressure is too high and the pressure of the crimping edge is insufficient, it may cause material extrusion; conversely, if the pressure of the crimping edge is too high and the injection pressure is insufficient, it may cause incomplete material filling. Therefore, the two are equal to achieve the best filling effect and prevent material overflow.
[0083] Furthermore, if the injection pressure is greater than the pressure at the crimping edge, the substrate 2 may be locally overstressed, thereby causing deformation or cracks. By making the two pressures equal, the stress concentration phenomenon caused by uneven pressure can be reduced, and the stability of the finished product can be improved.
[0084] The consistent pressure distribution helps to form a uniform and dense light-transmitting member 4, which not only improves the appearance quality of the product, but also helps the functional performance of the phototherapy device, such as uniform diffusion of light.
[0085] According to one embodiment of the present application, after the injection molding machine is controlled to complete the injection molding of the light-transmitting material, the injection molding of the light-transmitting material is stopped, and the injection molding machine is controlled to continue to maintain the injection pressure for a preset time period.
[0086] Specifically, when the light-transmitting material is completely injected into the receiving groove 6, the injection of new material is stopped. However, the injection molding machine does not release the pressure immediately, but maintains a certain pressure, which can be called the pressure holding stage. The length of the pressure holding time can be determined according to factors such as the characteristics of the material, temperature, and mold design. For example, this time is enough for the material to begin to solidify initially, but still allows the material to have a certain fluidity in order to better fill the space. When the preset time is reached, the injection molding machine will gradually release the pressure, allowing the material to continue to cool and solidify naturally.
[0087] The embodiment of the present application can ensure that all the gaps are filled with material before the material begins to solidify by maintaining a certain injection pressure. Even after the injection molding is completed, the material may continue to flow to fill the possible tiny gaps.
[0088] It is understandable that the light-transmitting material may shrink during the cooling process. If the pressure is released immediately after the injection molding is completed, it may cause uneven shrinkage, thereby affecting the quality and appearance of the product. By maintaining the pressure, the adverse effects of shrinkage can be reduced, and the material molecules can be more closely combined, thereby improving the density of the material and enhancing the mechanical strength and optical properties of the light-transmitting member 4.
[0089] Furthermore, during the injection molding process, air may be mixed into the material, forming bubbles. Maintaining a certain pressure helps squeeze out the air, reducing or even eliminating bubbles and voids, thereby improving the transparency and flatness of the product. During the period of maintaining pressure, the material will fit more closely around the light strip 3, further enhancing the sealing of the phototherapy device.
[0090] Therefore, the embodiment of the present application can ensure that the light-transmitting material reaches the optimal state before curing through the above-mentioned pressure-maintaining measures, thereby improving the sealing and aesthetics of the phototherapy device.
[0091] According to an embodiment of the present application, there are multiple injection channels, and the multiple injection channels are arranged around the center of the boss. For example, there may be four injection channels, and the four injection channels are evenly distributed at the four corners of the boss.
[0092] Specifically, the design of multiple injection channels can reduce bubbles, voids or insufficient filling that may be caused by single-point injection, thereby improving the appearance quality and consistency of the finished product.
[0093] Furthermore, the light-transmitting material is filled uniformly from multiple directions, which can better fill various corners and gaps, reduce the gap between the material and the receiving groove 6 of the substrate 2, and thus improve the overall sealing performance.
[0094] In addition, simultaneous injection at multiple points can optimize the flow path of the material in the receiving groove 6, so that the material can cover the entire receiving groove 6 area more quickly, reduce flow dead corners, and help form a more uniform and dense light-transmitting member 4.
[0095] Therefore, the embodiment of the present application adopts a multi-channel injection molding design, which can not only significantly improve the injection molding efficiency, but also ensure the uniform distribution of the light-transmitting material in the receiving groove 6, thereby improving the sealing and appearance quality of the phototherapy device.
[0096] According to one embodiment of the present application, referring to Figure 2-Figure 4 As shown, the control box 1 includes a bottom shell 7, a circuit board 8, an electronic component 9 and a cover assembly 10, and a first opening 11 is provided on the top of the bottom shell 7; the steps of assembling the control box 1 include:
[0097] S201 , assembling the electronic components 9 on the circuit board 8 .
[0098] This step involves welding or otherwise fixing various required electronic functional components (such as rechargeable battery 12, charging interface 13, backlight panel 14, key 15, etc.) on circuit board 8. By completing the assembly of all electronic components in one step, production efficiency can be improved.
[0099] S202 , installing the circuit board 8 equipped with the electronic components 9 into the bottom housing 7 through the first opening 11 .
[0100] A first opening 11 is provided at the top of the bottom case 7, allowing the circuit board 8 with the electronic components 9 installed thereon to be placed into the bottom case 7 through the opening. This is done to facilitate the subsequent assembly steps and to pre-check whether the components on the circuit board 8 are correctly installed, thereby simplifying the subsequent assembly process and avoiding the need to operate multiple independent components in the narrow space of the bottom case 7.
[0101] S203 , cover the cover assembly 10 on the first opening 11 of the bottom shell 7 to close the circuit board 8 .
[0102] The last step is to close the first opening 11 on the bottom shell 7 with a cover assembly 10 to protect the internal circuit board 8 and electronic components 9. This step can be done by screwing or other mechanical fixing methods. By closing the cover assembly 10, the internal components can be effectively protected from the external environment.
[0103] Therefore, the embodiment of the present application can significantly reduce the assembly workload in the bottom shell 7 by completing the assembly of all electronic components 9 on the circuit board 8 in advance, thereby improving the overall production efficiency; and because the bottom shell 7 is sealed after the circuit board 8 is assembled, the sealing effect can be better controlled to reduce the risk of water vapor or dust entering. The present application achieves the purpose of improving processing efficiency and enhancing sealing by optimizing the assembly process of the control box 1.
[0104] According to one embodiment of the present application, referring to Figure 3 , Figure 4 and Fig. 9 As shown, the electronic component 9 includes a rechargeable battery 12 and a charging interface 13 , and the bottom shell 7 is provided with a mounting notch 16 .
[0105] The step of assembling the electronic component 9 on the circuit board 8 includes: electrically connecting the rechargeable battery 12 to the circuit board 8 , and electrically connecting the charging interface 13 to the circuit board 8 .
[0106] Specifically, the rechargeable battery 12 is one of the important components of the phototherapy device, which can power the entire device. The charging interface 13 is the interface for the user to charge the device, and is also the connection point between the circuit board 8 and the external power supply. Directly welding the charging interface 13 to the circuit board 8 can ensure good electrical contact and facilitate user operation.
[0107] The step of installing the circuit board 8 equipped with the electronic components 9 into the bottom shell 7 through the first opening 11 includes: installing the rechargeable battery 12 into the bottom shell 7 through the first opening 11, and then covering the circuit board 8 on the rechargeable battery 12 through the first opening 11, and installing the charging interface 13 on the circuit board 8 into the installation notch 16 of the bottom shell 7.
[0108] Specifically, firstly, the rechargeable battery 12 is placed into the bottom shell 7 through the first opening 11 at the top of the bottom shell 7. This is to ensure that the battery can be safely placed in a predetermined position and will not be affected by the external environment, thereby ensuring accurate positioning of the battery and avoiding accidental damage to the battery in subsequent operations.
[0109] Next, the circuit board 8 with the charging interface 13 and the rechargeable battery 12 installed is placed into the bottom case 7 through the first opening 11, and is covered on the rechargeable battery 12. This ensures a tight physical connection between the circuit board 8 and the battery, facilitates subsequent operations, and helps improve the overall mechanical stability.
[0110] The last step is to align the charging interface 13 on the circuit board 8 with the installation notch 16 on the bottom shell 7 and ensure that it is installed in place. This ensures that the position of the charging interface 13 is accurate, which is convenient for users to perform charging operations and improves the user experience of the product.
[0111] Therefore, the embodiment of the present application greatly simplifies the assembly process and reduces the workload of handling each component separately by directly mounting the rechargeable battery 12 and the charging interface 13 on the circuit board 8 and then mounting them as a whole in the bottom case 7. In addition, by covering the rechargeable battery 12 with the circuit board 8, the safety and stability of the rechargeable battery 12 can be improved.
[0112] According to one embodiment of the present application, referring to Figure 3 and Figure 4 As shown, the electronic component 9 further includes a backlight plate 14, and the cover plate assembly 10 includes a lens 17 having a pattern structure.
[0113] The step of assembling the electronic component 9 on the circuit board 8 also includes: electrically connecting the backlight panel 14 to the side of the circuit board 8 facing away from the rechargeable battery 12 .
[0114] Specifically, the main function of the backlight panel 14 is to provide lighting when needed to highlight the pattern structure on the lens 17. Installing the backlight panel 14 on the side of the circuit board 8 away from the rechargeable battery 12 can ensure that it does not interfere with the installation of the battery and can effectively illuminate the lens 17 when working.
[0115] The step of covering the cover assembly 10 on the first opening 11 of the bottom shell 7 to close the circuit board 8 includes: covering the lens 17 on the first opening 11 of the bottom shell 7 and corresponding to the backlight plate 14 so that the lens 17 displays a pattern structure through the backlight plate 14.
[0116] Specifically, the lens 17 is a part of the cover assembly 10, and has a pattern structure thereon, which can be a brand logo, an operation prompt or other decorative elements. The lens 17 is covered at the first opening 11 of the bottom shell 7, and it is ensured to correspond to the backlight panel 14, so that the pattern structure can be clearly visible when the backlight panel 14 is lit. Such a design not only increases the visual appeal of the device, but also helps users quickly identify the functional area or operation button of the device in low light conditions.
[0117] According to one embodiment of the present application, referring to Figure 4 As shown, the electronic component 9 further includes a button 15 , and the cover assembly 10 further includes a pressing plate 18 arranged side by side with the backlight plate 14 .
[0118] The step of assembling the electronic component 9 on the circuit board 8 also includes: electrically connecting the button 15 to the side of the circuit board 8 facing away from the rechargeable battery 12 .
[0119] Specifically, the button 15 is an important interface part for the user to interact with the device, and it can be used for operations such as starting and shutting down the device. Installing the button 15 on the side of the circuit board 8 away from the rechargeable battery 12 can ensure that the position of the button 15 does not interfere with the installation of the rechargeable battery 12, and can be convenient for the user to press, ensuring the compactness of the layout of the circuit board 8. This layout ensures the response speed and stability of the button 15, and is also conducive to simplifying the design of the circuit board 8 and improving the overall assembly efficiency.
[0120] The step of covering the cover assembly 10 on the first opening 11 of the bottom shell 7 to close the circuit board 8 also includes: covering the pressing plate 18 on the first opening 11 of the bottom shell 7 and corresponding to the button 15 to press the button 15 through the pressing plate 18.
[0121] Specifically, the pressing plate 18, as a part of the cover assembly 10, mainly functions to provide an interface that the user can press, and the pressing plate 18 corresponds to the position of the key 15 to ensure that the key 15 can be accurately triggered when the user presses the pressing plate 18. Through the design of the pressing plate 18, the internal key 15 can be protected from external factors (such as dust, moisture, etc.), and the service life and operational reliability of the key 15 can also be improved.
[0122] According to one embodiment of the present application, referring to Figure 4-Figure 6 , Fig. 9 As shown, a first step portion 19 is provided at the first opening 11 of the bottom shell 7 , a first connecting column 20 and a second connecting column 21 are provided on the inner side wall of the first step portion 19 , and the cover plate assembly 10 further includes a frame cover 22 .
[0123] The step of installing the circuit board 8 equipped with the electronic components 9 in the bottom shell 7 through the first opening 11 also includes: connecting the circuit board 8 to the first connecting column 20 through a first fastener (not shown in the figure).
[0124] Specifically, the first connecting column 20 is located on the inner wall of the first step portion 19 at the first opening 11 of the bottom case 7. By connecting the circuit board 8 to the first connecting column 20 using a first fastener (such as a screw, a buckle, etc.), the circuit board 8 can be ensured to be fixed and stable in the bottom case 7, avoiding displacement or vibration during use, thereby improving the reliability and service life of the device.
[0125] The step of covering the cover assembly 10 on the first opening 11 of the bottom shell 7 to close the circuit board 8 also includes: covering the frame cover 22 on the circuit board 8 and connecting it to the second connecting column 21 through a second fastener (not shown in the figure) so that the frame cover 22 overlaps the first step portion 19, and then covering the lens 17 and the pressing plate 18 on the frame cover 22.
[0126] Specifically, the frame cover 22 is a part of the cover assembly 10, and a connection hole 23 corresponding to the second connection column 21 is provided on the frame cover 22, and the connection hole 23 is connected to the second connection column 21 through a second fastener (such as a screw, a buckle, etc.). In this way, the frame cover 22 can be tightly fitted on the circuit board 8 and overlapped on the first step portion 19. The design of the frame cover 22 can not only protect the circuit board 8 and other electronic components, but also enhance the overall sealing and structural stability by overlapping with the first step portion 19.
[0127] After the frame cover 22 is covered and fixed, the next step is to cover the lens 17 and the pressing plate 18 on the frame cover 22. The positions of the lens 17 and the pressing plate 18 correspond to the backlight plate 14 and the button 15 mentioned above, so as to ensure that the user can trigger the button 15 through the pressing plate 18 and illuminate the pattern structure on the lens 17 through the backlight plate 14.
[0128] The multi-layer covering design of the embodiment of the present application not only improves the aesthetics of the device, but also enhances the overall protection performance, allowing the device to work normally in various environments.
[0129] According to one embodiment of the present application, referring to Figure 4 and Fig.10 As shown, the frame cover 22 is provided with a first through hole 24, a second through hole 25 and an avoidance hole 26, and the bottom of the pressing plate 18 is provided with a pressing portion 27 and a positioning portion 28. These holes are designed to ensure that each component can be correctly aligned and perform its function.
[0130] The step of covering the frame cover 22 on the circuit board 8 includes: covering the frame cover 22 on the circuit board 8, and arranging the backlight plate 14 on the circuit board 8 in the avoidance hole 26, and the button 15 on the circuit board 8 corresponds to the first through hole 24.
[0131] Specifically, the avoidance hole 26 is designed to allow the backlight plate 14 on the circuit board 8 to be exposed, ensuring that the light can smoothly pass through the lens 17 to display the pattern structure. The existence of the avoidance hole 26 ensures that the light of the backlight plate 14 will not be blocked by the frame cover 22, so that the backlight plate 14 can emit light normally and illuminate the pattern structure on the lens 17.
[0132] The position of the first through hole 24 corresponds to the key 15 on the circuit board 8 , so as to ensure that the pressing portion 27 of the pressing plate 18 can be accurately aligned with and pressed onto the key 15 , thereby realizing the function of the key 15 .
[0133] The step of covering the pressing plate 18 on the frame cover 22 includes: aligning the pressing portion 27 of the pressing plate 18 with the first through hole 24 , and connecting the positioning portion 28 of the pressing plate 18 to the second through hole 25 .
[0134] Specifically, the entire pressing plate 18 can be made of TPU (thermoplastic polyurethane elastomer) material, which has good elasticity and wear resistance and is suitable for parts that need to be pressed frequently. When the user applies pressure to the pressing plate 18, the pressing portion 27 passes through the first through hole 24 and then presses the button 15 on the circuit board 8 to trigger the corresponding function.
[0135] The positioning portion 28 is designed to ensure that the pressing plate 18 can be quickly and accurately installed on the frame cover 22. By connecting the positioning portion 28 to the second through hole 25, rapid positioning and assembly can be achieved, ensuring that the position of the pressing plate 18 is accurate and improving assembly efficiency.
[0136] According to one embodiment of the present application, referring to Figure 4 As shown, the step of covering the lens 17 and the pressing plate 18 on the frame cover 22 includes: bonding the lens 17 and the pressing plate 18 to the frame cover 22 through the adhesive 29.
[0137] Specifically, the lens 17 is located at the outermost layer of the frame cover 22, with a pattern structure thereon, and is the part that the user directly sees. The lens 17 is bonded to the frame cover 22 using an adhesive (such as glue, double-sided tape or other suitable adhesive materials) to ensure that the lens 17 is firmly fixed in a designated position. The application of the adhesive 29 can ensure a tight bond between the lens 17 and the frame cover 22, preventing the lens 17 from falling off or moving during use, and improving the sealing and aesthetics of the device.
[0138] Similarly, the pressing plate 18 is bonded to the frame cover 22 using an adhesive 29 to ensure the stability and position accuracy of the pressing plate 18. The application of the adhesive 29 can ensure that the pressing plate 18 will not be displaced when pressed by an external force, thereby ensuring the accuracy of user operation and the reliability of the device.
[0139] For example, the adhesive 29 includes a first adhesive body 30 and a second adhesive body 31. The first adhesive body 30 is a ring that matches the frame cover 22. The lens 17 is bonded to the frame cover 22 through the first adhesive body 30. The second adhesive body 31 is connected to the end of the first adhesive body 30. The pressing plate 18 is bonded to the frame cover 22 through the second adhesive body 31.
[0140] According to one embodiment of the present application, referring to Figure 6 and Fig. 9 As shown, the control box 1 includes a bottom shell 7 and a cover assembly 10 . The bottom shell 7 is provided with a first opening 11 . The cover assembly 10 covers the first opening 11 , and a connecting groove is provided between the cover assembly 10 and the end of the bottom shell 7 adjacent to the first opening 11 .
[0141] The step of placing the control box 1 in a first injection mold, and injection molding the substrate 2 in the first injection mold to construct a base 5 on one side of the substrate 2 that is injection molded and wrapped around the control box 1 includes:
[0142] The control box 1 is placed upside down in the first injection mold, and the material of the injection-molded substrate 2 is controlled to flow into the connection groove, so as to form a flange 36 at the end of the base 5 that is embedded in the connection groove and covers the end of the bottom shell 7 adjacent to the first opening 11.
[0143] Specifically, the control box 1 is placed upside down in the first injection mold to ensure that the base 5 can be accurately formed and connected to the control box 1 during the injection molding process. In this way, the connection strength and sealing between the base 5 and the control box 1 can be ensured.
[0144] During the injection molding process, the base 5 is injection molded to match the design of the bottom shell 7, which ensures that the base 5 can be tightly combined with the bottom shell 7 to form a solid overall structure. The base 5 is injection molded with a charging port 33 corresponding to the charging interface 13, which ensures that the position of the charging port 33 is accurate, making it convenient for users to connect the charging cable 34 of the charger to the charging interface 13 through the charging port 33 to achieve charging operation.
[0145] A second step portion 32 is also provided at the first opening 11 of the bottom shell 7. The second step portion 32 is provided on the outer side of the first step portion 19. A second opening 35 is injection molded at one end of the base 5 adjacent to the first opening 11. A flange 36 is molded at the end of the base 5 adjacent to the second opening 35. The flange 36 is embedded in the connecting groove and covers the end of the bottom shell 7 adjacent to the first opening 11, and is connected to the second step portion 32 at the same time.
[0146] The design of the flange 36 can enhance the connection strength between the base 5 and the bottom shell 7 to prevent the two from separating, and since a flange 36 sealing structure is formed in the connection groove, moisture or other external substances can be effectively prevented from entering the interior of the device.
[0147] Therefore, the embodiment of the present application forms a base 5 by inverting the control box 1 in the first injection mold of the injection molding substrate 2, which not only improves the sealing and waterproof properties of the device, but also enhances the structural strength and simplifies the assembly process.
[0148] According to one embodiment of the present application, referring to Figure 6As shown, the outer side of the end portion of the bottom shell of the control box 1 adjacent to the first opening has a chamfered portion 39. With such a design, the connection area of the base 5 at the chamfered portion 39 can be increased, thereby improving the tightness of the connection.
[0149] According to one embodiment of the present application, referring to Figure 4 , Figure 7-Figure 9 As shown, the control box 1 further includes a circuit board 8 disposed in the bottom shell 7 , the circuit board 8 is electrically connected to a wire (not shown in the figure), and a wire hole 37 is provided at the bottom of the bottom shell 7 .
[0150] During the injection molding process of the base 5 , a wire harness hole 38 communicating with the wire passing hole 37 and the accommodating groove 6 is injection molded at the bottom of the base 5 .
[0151] The step of electrically connecting the light strip 3 to the control box 1 includes: passing the wires through the wire holes 37 and the wire harness holes 38 and electrically connecting the wires to the light strip 3 .
[0152] Specifically, the bottom of the bottom shell 7 is provided with a wire hole 37, and during the injection molding process, the bottom of the base 5 is injection molded with a wire hole 38 connected to the wire hole 37 and the receiving groove 6. Through the design of the wire hole 37 and the wire hole 38, the wire can start from the circuit board 8, pass through the wire hole 37 to the wire hole 38 at the bottom of the base 5, and finally be electrically connected to the light strip 3 in the receiving groove 6.
[0153] The embodiment of the present application reasonably designs the wire holes 37 and the wire bundle holes 38 and arranges the wires in an orderly manner inside the device, thereby avoiding the situation where the wires are in a disorderly manner inside the device, which is beneficial to reducing the overall volume of the device, improving the space utilization of the device, and enhancing the reliability of the device.
[0154] According to one embodiment of the present application, referring to Figure 5 As shown, during the injection molding process of the base 5, the cross-sectional area of the base 5 gradually increases along the direction from the end of the base 5 to the substrate 2, that is, from left to right. On the one hand, the thickening design is beneficial to improve the connection strength and stability, and on the other hand, it is convenient to demold during injection molding.
[0155] According to an embodiment of the present application, the bottom shell 7 of the control box 1 is made of hard material.
[0156] Specifically, the bottom shell 7 of the control box 1 is a hard shell having high strength and rigidity, and can effectively protect the internal circuit board 8, rechargeable battery 12 and other components from damage when the device is subjected to external impact or pressure, thereby extending the service life of the device and reducing maintenance costs.

[0160] The frame cover 22 is covered on the circuit board 8 and connected to the second connection column 21 by screws, so that the frame cover 22 is stably overlapped on the first step portion 19 of the bottom shell 7, and then the lens 17 and the pressing plate 18 are bonded and covered on the frame cover 22 by double-sided tape. The positions of the lens 17 and the pressing plate 18 correspond to the backlight plate 14 and the button 15 on the circuit board 8, so as to ensure that the user can trigger the button 15 through the pressing plate 18 and illuminate the pattern structure on the lens 17 through the backlight plate 14.
[0161] 2. A substrate 2 is formed by injection molding at one time.
[0162] Specifically, the control box 1 is inverted in the first injection mold, and the silicone material of the substrate 2 is injection-molded in the first injection mold to form a base 5 compatible with the bottom shell 7 and a receiving groove 6 for installing the light strip 3, and during the injection molding process, the bottom of the base 5 is injection-molded to form a wiring hole 38 connected to the wire hole 37 and the receiving groove 6, the side of the base 5 is injection-molded to form a charging port 33 corresponding to the charging interface 13, and the second opening 35 is injection-molded at one end of the base 5 adjacent to the first opening 11, and the silicone material of the injection-molded substrate 2 is controlled to flow into the connecting groove at the end of the control box 1, so as to form a flange 36 embedded in the connecting groove and covering the end of the bottom shell 7 adjacent to the first opening 11 at the end of the base 5, and the flange 36 is connected to the second step portion 32.
