[0023] Reference Figures 1 to 5 This utility model proposes a switchable mechanism for use with reversing lights and rear fog lights.

[0024] In this embodiment of the utility model, specifically, the switchable mechanism includes: a functional module 100, a base 12, a heat sink 16, a connecting seat 17, a sealing ring 22, a switching structure 23, and a face shield 28. Preferably, the connecting seat 17 can be made of polyphenylene sulfide, which has high heat resistance, chemical corrosion resistance, flame retardancy, high rigidity, high strength, and is not easily damaged during disassembly and assembly, but is not limited to this. Preferably, the sealing ring 22 can be made of foamed silicone, which has strong resilience, shock absorption and buffering effects, strong sealing performance, protects the functional module 100, is resistant to high and low temperatures, has a long lifespan, and is not easily brittle, but is not limited to this. The heat sink 16 can be made of aluminum, which has high heat dissipation efficiency, is easy to process, lightweight, and has low cost. The base 12 has a mounting groove 12a, and the heat sink 16 is installed in the mounting groove 12a by screws. The face shield 28 is fixed to the base 12 by screws. Preferably, the material of the faceplate 28 can be either PMMA or PC dual-color material. That is, the reversing light faceplate is made of PMMA material, and the inner side is often designed with a light texture to help the light diffuse evenly; the rear fog light is made of PC material with a transmittance of 0.9 or higher, and the inner side is often designed with light-concentrating ribs to enhance the penetration of the light spot, but it is not limited to this. The base 12 is permanently sealed and fixed to the vehicle body by ultrasonic welding.

[0025] Please refer to Figures 1 to 5 The functional module 100 is fixed to the connecting seat 17, and the switching structure 23 passes through the connecting seat 17 and is fixed to the functional module 100. The sealing ring 22 is installed in the base 12 in a groove and is in contact with the connecting seat 17. It can be understood that the connecting seat 17 has a sealing ring groove. The depth of the sealing ring groove is less than the wire diameter of the sealing ring 22, so that it is not easy to be compressed. The width of the sealing ring groove is greater than the wire diameter of the sealing ring 22 and greater than the contact surface with the connecting seat 17, so as to reserve space for the sealing ring 22 to be deformed under pressure.

[0026] The connector 17 includes a fixing plate 21, which is permanently sealed and fixed to the connector 17 by ultrasonic welding. The functional module 100 includes a first unit 10 and a second unit 11. The first unit 10 includes a first lens 10a and a first component 10b, and the second unit 11 includes a second lens 11a and a second component 11b. The first lens 10a or the second lens 11a is fixed to the fixing plate 21 with screws. Figures 3 to 5 This is a schematic diagram of the second unit 11, which is the rear fog light related component. The position of the second unit 11 can be switched to the first unit 10, which is the reversing light related component. Figures 3 to 5(Not shown). It can be understood that the first component 10b can be a reversing light-related component, including an LED light source emitting white light and a corresponding LED driver board electrically connected to the LED light source. The second component 11b can be a rear fog light-related component, including an LED light source emitting red or amber light and a corresponding LED driver board electrically connected to the LED light source. The reversing light driver board and the rear fog light driver board have different resistance values, which can be distinguished using an identification resistor. Preferably, the first lens 10a and the second lens 11a can be colorless and transparent, made of PMMA, but are not limited to this. The heat sink 16 is provided with several positioning grooves 29 and fitting grooves 31. The first component 10b and the second component 11b are each provided with several positioning posts 30, each positioning post 30 fitting into a corresponding positioning groove 29. The fitting groove 31 secures and positions the first component 10b or the second component 11b. Understandably, each positioning post 30 is engaged with the corresponding positioning groove 29, and the first component 10b or the second component 11b is engaged with the fitting groove 31 to prevent the functional module 100 from being misinstalled.

[0027] Please refer to Figure 3 and Figure 5The switching structure 23 includes a plurality of first spring members 24, a plurality of second spring members 25, and an adjusting plate 26, the adjusting plate 26 being mounted on the connecting seat 17. Each first spring member 24 includes a first part 24a, a second part 24b, and a third part 24c connecting the first part 24a and the second part 24b. Each second spring member 25 includes a fourth part 25a, a fifth part 25b, and a sixth part 25c connecting the fourth part 25a and the fifth part 25b. Spring screws can be optionally used for the plurality of first spring members 24 and the plurality of second spring members 25. The third part 24c passes through the fixing plate 21 and the first lens 10a or the second lens 11a. The first part 24a limits the first lens 10a or the second lens 11a, and the second part 24b is fixed to the first assembly 10b or the second assembly 11b. The fourth part 25a limits the fixing plate 21, the sixth part 25c passes through the fixing plate 21, and the fifth part 25b is fixed to the adjusting plate 26. Understandably, the third part 24c is identical to the sixth part 25c and includes a spring. The two ends of the spring in the third part 24c abut against the fixing plate 21 and either the first component 10b or the second component 11b, respectively. The two ends of the spring in the sixth part 25c abut against the fixing plate 21 and the adjusting plate 26, respectively. The second part 24b and the fifth part 25b are threaded portions. The first component 10b, the second component 11b, and the adjusting plate 26 each have threaded holes. The threaded portions of the second part 24b and the fifth part 25b are tightened and secured with the corresponding threaded holes of the first component 10b or the second component 11b and the adjusting plate 26. The first part 24a is identical to the fourth part 25a. The fixing plate 21, the first lens 10a, and the second lens 11a each have several through holes. The diameter of these through holes is smaller than the diameter of the first part 24a and the fourth part 25a. The first part 24a can limit the movement of the first lens 10a or the second lens 11a, and the fourth part 25a prevents the displacement of several second spring components 25.

[0028] The switching structure 23 includes several connectors 27, each connector 27 having its two ends fixed to the corresponding first part 24a and the corresponding fourth part 25a with screws. The connecting seat 17 is provided with a receiving groove 17a and several sliding grooves 20. The first lens 10a or the second lens 11a is fixed to the receiving groove 17a by ultrasonic welding. Each second spring member 25 slides in the corresponding sliding grooves 20 and is confined within the corresponding sliding groove 20.

[0029] Please refer to Figures 3 to 5The base 12 has several locking protrusions 14, and the heat sink 16 is mounted on the base 12 and includes several interfaces 15. The connector 17 has several grooves 18 and guide grooves 19. The functional module 100 has a first position and a second position relative to the base 12 and includes several connecting ends 13. When the functional module 100 is in the first position, the locking protrusions 14 pass through the grooves 18, and the connecting ends 13 and interfaces 15 are interleaved but not electrically connected. When the functional module 100 is in the second position, the locking protrusions 14 are secured in the guide grooves 19, and the connecting ends 13 are engaged with the interfaces 15 and electrically connected. Preferably, the interfaces 15 can be selected as conductive contacts, and the connecting ends 13 can be selected as spring pins. The spring pins can withstand tens of thousands or even hundreds of thousands of insertions and removals without loosening and causing power failure under vehicle vibration conditions.

[0030] Each protrusion 14 has a slot 14a, and the guide groove 19 has a plurality of protrusions 19a, each protrusion 19a engaging with the corresponding slot 14a. When the functional module 100 is in the first position, the adjusting plate 26 abuts against the connecting seat 17; when the functional module 100 is in the second position, the adjusting plate 26 abuts against the plurality of protrusions 14, and the plurality of protrusions 19a are secured in the corresponding slots 14a.

[0031] In this invention, when the reversing light or rear fog light functional module 100 of a car malfunctions, it is removed. The connecting seat 17 is pressed to compress the sealing ring 22, causing several protrusions 14 to support the switching structure 23. Several connecting ends 13 disengage from several interfaces 15. The connecting seat 17 is rotated to the first position, and the connecting seat 17 and the malfunctioning reversing light or rear fog light functional module 100 are removed. When the reversing light or rear fog light functional module 100 needs to be installed on the car, several protrusions 14 are aligned and pass through several grooves 18. The connecting seat 17 is pressed, causing several protrusions 14 to support the switching structure 23. The connecting seat 17 is rotated again to the second position and then released. Several connecting ends 13 engage with several interfaces 15, and the switching structure 23 is activated. 3. The flexible release fixing connector 17 and functional module 100 are connected by several connecting ends 13 and several interfaces 15 to complete the installation. It can be seen that the base 12 is fixed to the vehicle body and has a structure for installing the functional module 100. Only the reversing light or rear fog light functional module 100 needs to be replaced. The reversing light and rear fog light can be easily disassembled and switched, which greatly reduces the cost. Rotating and pressing the connector 17 simplifies the installation and disassembly steps of the relevant functional module 100. The connector 17 must be rotated to the second position for several connecting ends 13 of the functional module 100 to be engaged with several interfaces 15 of the radiator 16 and connected, preventing the functional module 100 from being confused and ensuring safety and reliability.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
