DETAILED DESCRIPTION

[0025] The following is a combination of the appended examples of the present invention Figure 1-3 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example:

[0027] like Figures 1 to 3 As shown, the present invention discloses a fuel tank heating transfer switch with a light-emitting function. The switch comprises a housing, which includes a base 12 and an upper cover 11 rotatably connected to the base 12. In the prior art, the base 12 is internally mounted with a main circuit board assembly 13, a microswitch 131, a push pin 132, and other structures. The main operating principle is that when the upper cover 11 swings, it pushes the push pin 132 to activate the microswitch 131, or cancels the push of the push pin 132, disconnecting it from the microswitch 131, thereby connecting or disconnecting the circuit required for fuel tank heating. The upper cover 11 is provided with a light-transmitting mechanism, and the base 12 is provided with a light-emitting mechanism.

[0028] The light-emitting mechanism includes a backlight circuit board 15 fixedly arranged inside the base 12 and lamp beads 151 electrically connected to the backlight circuit board 15. In addition, in this structure, the main circuit board assembly 13 is not only used in conjunction with the micro switch 131 to connect the circuit required for fuel tank heating, but also serves to power the backlight circuit board 15 assembly so that the lamp beads 151 can continue to light up.

[0029] The light-transmitting mechanism includes a light-transmitting plate 14 inserted in the middle of the upper cover 11. One end of the light-transmitting plate 14 is fixedly connected to the upper cover 11, and the other end extends through the upper cover 11 into the interior of the base 12. At the same time, the backlight circuit board 15 is arranged above the main circuit board assembly 13 and close to the light-transmitting plate 14.

[0030] The working principle of the above structure is: after the car is started, the main circuit board assembly 13 supplies power to the backlight circuit board 15, so that the lamp beads 151 on the backlight circuit board 15 continue to emit light. At this time, the bright light emitted by the lamp beads 151 can be reflected by the light-transmitting plate 14, so that the driver can quickly see the position of the fuel tank heating switch.

[0031] An extension portion 141 extends downward on both sides of the lower end of the light-transmitting plate 14. The extension portion 141 is integrally formed with the light-transmitting plate 14. Two lamp beads 151 are provided and are located directly below the extension portion 141. At the same time, a through groove 152 is opened in the middle of the backlight circuit board 15, and the through groove 152 passes through the upper and lower ends of the backlight circuit board 15.

[0032] The design significance of this structure is that: in most existing fuel tank heating conversion switches, a fixing rod 17 for maintaining the swinging state of the upper cover 11 is provided at the lower middle end of the upper cover 11. The working principle of the fixing rod 17 is the existing technology, and this article only briefly describes it: mainly, a steel ball 171 is retractably provided at the lower end of the fixing rod 17, and a spring is fixedly connected between the steel ball 171 and the fixing rod 17, which is not shown in the figure. At the same time, a multi-fold plate 18 is provided at the lower end of the steel ball 171 of the base 12. When the upper cover 11 swings, the steel ball 171 will be embedded in the groove of the multi-fold plate 18 under the action of the spring, thereby playing the role of fixing the swinging state of the upper cover 11. Since this structure overlaps with the installation position of the light-transmitting plate 14, in order not to hinder the normal operation of the fixing rod 17, the light-transmitting plate 14 will have extensions 141 extending downward on both sides of the fixing rod 17 so that the light-transmitting plate 14 can be as close to the lamp beads 151 as possible. At the same time, when the lamp beads 151 are located directly below the extensions 141, it means that the backlight circuit board 15 is also located exactly below the central area of ​​the upper cover 11. Therefore, a through groove 152 is also required to be opened in the middle of the backlight circuit board 15 to prevent the moving path of the fixing rod 17 from being blocked. In addition, the base 12 is also provided with components such as a top pin 132 for linkage with structures such as the micro switch 131, but these structures are not necessarily concentrated in the central area of ​​the base 12, so this article does not specifically provide other avoidance grooves for these components. However, in specific production and manufacturing, the through-groove 152 is not limited to the groove for the passage of the fixing rod 17. All avoidance grooves on the backlight circuit board 15 that have the same or similar functions as the through-groove 152 can be included in the semantic scope of the through-groove 152.

[0033] Light guide plates 16 are provided on both sides of each extension portion 141 . In this structure, the lamp beads 151 are arranged between the two light guide plates 16 . Furthermore, the light guide plates 16 are located between the backlight circuit board 15 and the upper cover 11 and are fixed inside the base 12 .

[0034] In addition, the light guide plate 16 is made of flexible material and its upper end is fixedly connected to the extension portion 141. At the same time, a holder 161 is provided in the middle of the light guide plate 16 and the holder 161 is fixedly connected to the base 12. Finally, the light guide plate 16 is fixedly attached to the inner side wall of the holder 161.

[0035] This structure is mainly used to further gather the light source onto the extension portion 141 so that the light-transmitting plate 14 can project a light source with higher brightness.

[0036] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
