[0035] Example 1:

[0036] This invention provides a structure for a car pedal backlight, see [link / reference]. Figures 1-7 As shown, it includes: a backlight mounting groove 2 disposed on the upper surface of the pedal body 1, a backlight module 3 disposed in the backlight mounting groove 2, a panel 4 disposed above the backlight module 3, the panel 4 disposed within a frame assembly, the frame assembly including a first rectangular frame 5, the outer wall of the first rectangular frame 5 being fitted with the inner wall of the backlight mounting groove 2, a second rectangular frame 6 disposed inside the first rectangular frame 5, the outer wall of the second rectangular frame 6 being connected to the inner wall of the first rectangular frame 5, the lower surface of the panel 4 being bonded to the upper surface of the second rectangular frame 6, the outer periphery of the panel 4 being bonded to the inner wall of the first rectangular frame 5, the upper surface of the first rectangular frame 5, the upper surface of the panel 4 and the upper surface of the pedal body 1 being on the same plane, and the frame assembly being detachably connected to the backlight mounting groove 2 via a connecting mechanism.

[0037] The working principle and beneficial effects of the above technical solution are as follows: A backlight mounting groove 2 is opened on the upper surface of the pedal body 1. The backlight mounting groove 2 is used to install a backlight module 3. The backlight module 3 can generate luminous patterns and display them through the panel 4, making it easy for users to confirm the position of the car pedal and facilitating user use. The luminous patterns can also enhance the appearance of the vehicle, making it more aesthetically pleasing. After the backlight module 3 is installed, a frame assembly is made. The frame assembly includes a first rectangular frame 5 and a second rectangular frame 6 installed inside the first rectangular frame 5. The lower surface of the second rectangular frame 6 is flush with the lower surface of the first rectangular frame 5. Then, the panel 4 is installed into the frame assembly. The upper surface of the second rectangular frame 6 provides support for the panel 4. The panel 4 and the first rectangular frame 5 and the second rectangular frame 6 are connected. The rectangular frame 6 is bonded at the contact point with sealant. Then, the frame assembly with panel 4 is installed into the backlight mounting slot 2. The frame assembly is connected to the backlight mounting slot 2 through a connecting mechanism. When panel 4 is damaged, the sealant can be melted by heating, allowing panel 4 to be removed and replaced with a new panel 4 without having to remove the frame assembly multiple times. This improves the convenience of replacing panel 4. The replacement process does not require replacing the frame assembly, thus reducing maintenance costs and saving on usage costs. The reduced number of times the frame assembly is disassembled also extends its service life. Furthermore, the frame assembly is detachably connected to the backlight mounting slot 2 through the connecting mechanism, making it less prone to damage during disassembly and further extending its service life.

[0038] Example 2

[0039] Based on the above embodiment 1, see Figure 2 As shown, the backlight module 3 includes a mounting frame 7. The bottom wall of the mounting frame 7 is connected to the bottom inner wall of the backlight mounting groove 2. The mounting frame 7 is sequentially bonded with a reflector 8, a light guide plate 9, a diffusion component 10 and a light shielding film 11 from bottom to top. A groove is opened in the center of the light guide plate 9, and a light source component 12 is set in the groove.

[0040] A pattern plate 13 is provided on the light-blocking film 11. The upper surface of the pattern plate 13 is in contact with the lower surface of the panel 4. A light-transmitting area is provided through the pattern plate 13.

[0041] The diffusion assembly 10 includes a lower diffuser sheet 1001, a lower prism sheet 1002, an upper prism sheet 1003, and an upper diffuser sheet 1004, which are sequentially bonded together from bottom to top.

[0042] The working principle and beneficial effects of the above technical solution are as follows: The backlight module 3 includes an externally mounted mounting frame 7. Within the mounting frame 7, from bottom to top, a reflective sheet 8, a light guide plate 9, a lower diffuser 1001, a lower prism sheet 1002, an upper prism sheet 1003, an upper diffuser 1004, and a light-shielding film 11 are sequentially bonded by optical adhesive. A groove in the center of the light guide plate 9 is used to mount a light source component 12. The light source component 12 is electrically connected to a controller located in the backlight mounting slot 2. The controller is electrically connected to a power supply, which can be a car battery, thereby powering the light source component 12. The light source component 12 can emit light. The reflective sheet 8 can reflect the light emitted by the light source component 12 towards the panel 4. The light guide plate 9 can guide the light to diffuse towards the panel 4. The lower diffuser 1001 and lower prism sheet 1002... The diffusion assembly 10, composed of the upper prism sheet 1003 and the upper diffuser sheet 1004, can diffuse the light guided by the light guide plate 9, so that the light has different emission angles and improves the visual effect. After the light passes through the diffusion, the light shielding film 11 filters out some unwanted light, further improving the light emission effect. The light passing through the light-transmitting area of ​​the pattern plate 13 can display the light-emitting pattern of the preset pattern shape on the panel 4. The pattern plate 13 is in contact with the lower surface of the panel 4, which can provide support for the hollow lower surface of the panel 4, thereby improving the reliability of the panel 4, preventing the panel 4 from breaking, and extending the service life of the panel 4. Furthermore, the pattern plate 13 can be directly replaced by removing the panel 4 or the frame assembly, which makes it convenient for users to change different patterns according to their own needs, making the pedal body 1 more aesthetically pleasing.

[0043] Example 3

[0044] Based on embodiment 1 or 2, the first rectangular frame 5 and the second rectangular frame 6 adopt an integrated molding design.

[0045] The working principle and beneficial effects of the above technical solution are as follows: the first rectangular frame 5 and the second rectangular frame 6 can be integrally molded using casting or injection molding processes according to the material selection, thereby improving the reliability and sealing of the connection between the first rectangular frame 5 and the second rectangular frame 6, achieving the effect of waterproofing and dustproofing, and extending the service life of the frame components.

[0046] Example 4

[0047] Based on any one of Examples 1-3, see Figure 3 , Figure 4 As shown, the inner wall of the first rectangular frame 5 is provided with several vertical glue storage grooves 14, and the upper surface of the second rectangular frame 6 is provided with several horizontal glue storage grooves 15.

[0048] The longitudinal glue storage tank 14 and the transverse glue storage tank 15 have serrated cross sections.

[0049] The working principle and beneficial effects of the above technical solution are as follows: Both the longitudinal glue storage tank 14 and the transverse glue storage tank 15 can store sealant, thereby increasing the amount of glue injected between the frame assembly and the panel 4, improving the sealing and reliability of the connection between the frame assembly and the panel 4, and the serrated longitudinal glue storage tank 14 and transverse glue storage tank 15 can reduce the overflow of sealant, without affecting the display of the luminous pattern on the panel 4, thus improving the installation quality of the panel 4.

[0050] Example 5

[0051] Based on any one of Examples 1-4, see Figure 1 , Figure 5 As shown, the connecting mechanism includes positioning rods 1601 symmetrically arranged on the lower surfaces of the left and right ends of the first rectangular frame 5. The upper ends of the positioning rods 1601 are fixedly connected to the lower surface of the first rectangular frame 5. Several elastic elements 1602 are arranged on the side of the positioning rods 1601 away from the backlight module 3. The end of the elastic element 1602 away from the positioning rods 1601 is connected to the locking rod 1603. A slider 1604 is arranged on the upper end of the locking rod 1603. The slider 1604 is slidably connected to the lower surface of the first rectangular frame 5. A locking block 1605 is arranged on the side of the locking rod 1603 away from the positioning rods 1601. The locking block 1605 is in the shape of a right trapezoid. The lower surface of the locking block 1605 is set as an inclined surface. The inner wall of the backlight mounting groove 2 is provided with a locking groove 1606 that matches the locking block 1605.

[0052] A drain hole 1607 is provided below the locking rod 1603. The drain hole 1607 passes through the pedal body 1. One end of the drain hole 1607 is connected to the inside of the backlight mounting groove 2, and the other end of the drain hole 1607 is connected to the bottom of the pedal body 1.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When installing the frame assembly, the first rectangular frame 5 is placed into the backlight mounting groove 2. The inclined surface of the lower surface of the locking block 1605 contacts the upper edge of the backlight mounting groove 2. The locking block 1605 is squeezed, causing the locking rod 1603 and the slider 1604 to move towards the positioning rod 1601. The elastic element 1602 is compressed. Then, the locking block 1605 enters the backlight mounting groove 2 and slides down along the inner wall of the backlight mounting groove 2 until the lower end of the positioning rod 1601 contacts the bottom wall of the backlight mounting groove 2. The sum of the height of the positioning rod 1601 and the height of the first rectangular frame 5 is equal to the depth of the backlight mounting groove 2. At this time, the locking block 1605 is inserted into the locking groove 1606. At this time, the first rectangular frame 5... Since it cannot move up and down, to improve the sealing of the frame assembly, a flange can be provided on the outer periphery of the first rectangular frame 5, and a sealing groove adapted to the flange is provided on the upper surface of the pedal body 1. To improve the stability of the connection between the frame assembly and the backlight mounting slot 2, a connecting mechanism can also be provided on the front and rear sides of the first rectangular frame 5, so that the front and rear sides of the first rectangular frame 5 are stably connected to the front and rear side walls of the backlight mounting slot 2. A drain hole 1607 is provided below the locking rod 1603. If sewage flows into the backlight mounting slot 2 from the gap between the first rectangular frame 5 and the backlight mounting slot 2, the sewage can be discharged from the drain hole 1607, avoiding water accumulation inside the backlight mounting slot 2, ensuring that the electrical appliances inside the backlight mounting slot 2 are not affected, and further extending the service life of the backlight structure.

[0054] Example 6

[0055] Based on Example 5, see Figure 1 , Figure 5As shown, a quick-release assembly is provided inside the pedal body 1. The quick-release assembly is used to disassemble the frame assembly. The quick-release assembly includes a first receiving cavity 1701 and a second receiving cavity 1702 disposed inside the pedal body 1. The first receiving cavity 1701 is horizontally disposed, and one end of the first receiving cavity 1701 is connected to the locking groove 1606 away from the locking block 1605. The second receiving cavity 1702 is cross-connected with the first receiving cavity 1701 and is perpendicular to the first receiving cavity 1701. The lower end of the second receiving cavity 1702 is connected to the lower part of the pedal body 1. A push switch 1703 is slidably disposed near the lower end of the second receiving cavity 1702. The push switch 1703 is slidably connected to the inner wall of the second receiving cavity 1702. A first linear rack 1704 is disposed at the upper end of the push switch 1703. The side of the first linear rack 1704 near the locking groove 1606 is slidably connected to the inner wall of the second receiving cavity 1702. The upper end of the linear rack 1704 extends above the first receiving cavity 1701 and is provided with an elastic element 1705. One end of the elastic element 1705 is connected to the upper end of the first linear rack 1704, and the other end of the elastic element 1705 is connected to the upper inner wall of the second receiving cavity 1702. A transverse rotating shaft 1706 is provided at the intersection of the first receiving cavity 1701 and the second receiving cavity 1702. The transverse rotating shaft 1706 is located on the side of the first linear rack 1704 away from the locking groove 1606. The transverse rotating shaft 1706 is rotatably connected to the inner walls of the front and rear sides of the second receiving cavity 1702. A driven gear 1707 is provided on the transverse rotating shaft 1706. The driven gear 1707 meshes with the side of the first linear rack 1704 away from the locking groove 1606. A second linear rack 1708 is slidably provided on the bottom wall of the first receiving cavity 1701. The upper surface of the second linear rack 1708 meshes with the driven gear 1707.

[0056] The working principle and beneficial effects of the above technical solution are as follows: When removing the frame assembly, press the push switch 1703 upwards. Push switches 1703 in different positions need to be pressed simultaneously. At this time, the push switch 1703 drives the first linear rack 1704 to slide upwards along the second receiving cavity 1702, and the second elastic element 1705 is compressed. The first linear rack 1704 drives the driven gear 1707 to rotate. The rotation of the driven gear 1707 drives the second linear rack 1708 to slide along the inner wall of the first receiving cavity 1701 towards the locking block 1605. The second linear rack 1708 contacts the locking block 1605 and pushes the locking block away from the locking groove 1606. Step 1605 separates the locking block 1605 from the locking groove 1606, allowing the frame assembly to be removed from the backlight mounting slot 2. No special tools are required for disassembly, enabling users to remove the frame assembly themselves, facilitating the replacement of the pattern plate 13 and providing convenience for users. Furthermore, all push-button switches 1703 must be pressed simultaneously during disassembly to prevent accidental contact with a single push-button switch 1703 during vehicle movement, which could cause the frame assembly to fall. The frame assembly can be disassembled without force, improving the efficiency of disassembly and assembly, preventing damage to the frame assembly, and extending its service life.

[0057] Example 7

[0058] Based on Example 5 or 6, see Figure 4 , Figure 6 , Figure 7 As shown, a sealing assembly is provided in the backlight mounting slot 2. The sealing assembly includes outer partition plates 1801 symmetrically arranged on the left and right sides of the backlight module 3. The lower end of the outer partition plate 1801 is fixedly connected to the bottom wall of the backlight mounting slot 2. The front and rear sides of the outer partition plate 1801 are respectively connected to the inner walls of the front and rear sides of the backlight mounting slot 2. The bottom wall of the second rectangular frame 6 is provided with a flow limiting groove 1802 corresponding to the upper end of the outer partition plate 1801.

[0059] The working principle and beneficial effects of the above technical solution are as follows: In order to protect the backlight module 3, a sealing component is also provided in the backlight mounting groove 2. The upper end of the outer partition plate 1801 is inserted into the flow limiting groove 1802. The outer partition plate 1801 is located on the outside of the backlight module 3, which can separate the backlight module 3 from the connecting mechanism, thereby protecting the backlight module 3 and preventing external sewage from flowing into the backlight module 3.

[0060] Example 8

[0061] Based on Example 7, see Figure 6 , Figure 7As shown, the sealing assembly also includes an inner partition plate 1803, which is located on the side of the outer partition plate 1801 away from the locking groove 1606. A movable sealing plate 1804 is provided at the lower end of the inner partition plate 1803. The movable sealing plate 1804 is slidably connected to the bottom wall of the backlight mounting groove 2. The movable sealing plate 1804 is made of magnetic material. An electromagnetic chuck 1805 is provided between the movable sealing plate 1804 and the backlight module 3. The electromagnetic chuck 1805 is fixedly connected to the bottom wall of the backlight mounting groove 2. A spring rod 1806 is provided between the inner partition plate 1803 and the outer partition plate 1801. The outer partition plate... A connecting hole 1807 is provided near the upper end of the outer partition plate 1801. A connecting hole 2 1808 is provided at the lower end of the outer partition plate 1801. A connecting hole 3 1809 is provided near the upper end of the inner partition plate 1803. The height of the connecting hole 3 1809 is higher than the height of the connecting hole 1807. A lower sealing plate 1810 and an upper sealing plate 1811 are provided between the connecting hole 1807 and the connecting hole 3 1809. The lower sealing plate 1810 is connected to the side wall of the outer partition plate 1801, and the upper sealing plate 1811 is connected to the side wall of the inner partition plate 1803. The upper surface of the lower sealing plate 1810 is in contact with the lower surface of the upper sealing plate 1811.

[0062] The working principle and beneficial effects of the above technical solution are as follows: The electromagnetic chuck 1805 is electrically connected to the controller. When the backlight module 3 is not working, the electromagnetic chuck 1805 is in a de-energized state. At this time, the lower sealing plate 1810 is in contact with the upper sealing plate 1811, and the outer partition plate 1801 and the inner partition plate 1803 can separate the backlight module 3 from the connecting mechanism, preventing sewage from entering the backlight module 3. When the backlight module 3 is working, the electromagnetic chuck 1805 is energized and generates magnetism. The electromagnetic chuck 1805 attracts the moving sealing plate 1804 to move closer to the backlight module 3, causing the spring rod 1806 to stretch, and the lower sealing plate 1810 and the upper sealing plate 1811 to separate. At this time, the heat generated by the backlight module 3 can flow into the space between the outer partition plate 1801 and the inner partition plate 1803 through the third connecting hole 1809, and flow to the other side through the first connecting hole 1807 and the second connecting hole 1808. The drain hole 1607 discharges wastewater to the outside of the backlight mounting slot 2, improving the heat dissipation performance of the backlight structure, ensuring the working performance of the backlight module 3, and extending the service life of the backlight module 3. The gas discharged during the heat dissipation process can blow away the drain hole 1607, thereby improving the wastewater discharge performance of the drain hole 1607 and reducing the degree of blockage of the drain hole 1607. Since the height of the first connecting hole 1807 is lower than the height of the third connecting hole 1809, when there is a lot of sewage on the side of the outer partition plate 1801 away from the backlight module 3, the sewage flows into the space between the outer partition plate 1801 and the inner partition plate 1803 through the first connecting hole 1807. The sewage will flow out along the second connecting hole 1808 and will not flow into the side of the inner partition plate 1803 near the backlight module 3 from the third connecting hole 1809 due to the obstruction of the upper sealing plate 1811, further protecting the backlight module 3.

[0063] The present invention also provides a method for manufacturing a structure for an automotive pedal backlight, comprising the following steps:

[0064] Step 1: Create a backlight mounting groove 2 on the upper surface of the pedal body 1;

[0065] Step 2: Install the backlight module 3 into the center of the bottom wall of the backlight mounting slot 2;

[0066] Step 3: Create the border components and connecting mechanisms;

[0067] Step 4: Install panel 4 into the frame assembly;

[0068] Step 5: Install the frame assembly with panel 4 installed into the backlight mounting slot 2 using the connecting mechanism.

[0069] The working principle and beneficial effects of the above technical solution are as follows: When manufacturing the backlight structure, a backlight mounting groove 2 is first opened on the upper surface of the pedal body 1. Then, the backlight module 3 is installed in the center of the bottom wall of the backlight mounting groove 2. Next, the frame assembly and connecting mechanism are made. Then, the panel 4 is glued and installed into the frame assembly with sealant. Finally, the frame assembly with the panel 4 installed can be installed into the backlight mounting groove 2 through the connecting mechanism. The sealant is a hot melt adhesive. When removing the panel 4, the edge of the panel 4 is heated and the sealant begins to melt, so the panel 4 can be directly removed, realizing the individual replacement of the panel 4, reducing maintenance costs. The frame assembly is detachably connected to the backlight mounting groove 2 through the connecting mechanism, making the frame assembly less prone to damage during disassembly and further extending the service life of the frame assembly.

[0070] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
