Description

Technical Field

[0001] The present invention relates to automotive parts, and particularly to an externally-opening and light-emitting handle for vehicles. Background Art

[0002] An externally-opening and light-emitting handle for vehicles is applicable to vehicles and other devices with independent externally-opening door handles, and can be used in the external environment of the vehicle body. Its feature is that on the basis of the basic function of providing a hand-held grip for opening and closing the door, it adds a function of the handle emitting light, which can play roles such as position reminder, human-computer interaction, and lighting decoration, endowing the handle with more functions and connotations.

[0003] CN215108033U discloses a light-emitting door handle, including a light-transmitting plate, a housing, and a light-emitting element. The interior of the housing is hollow and one end is provided with an opening communicating with the interior. The light-emitting element is arranged in the opening, and the light-transmitting plate covers the opening on the housing.

[0004] CN103273875B discloses an external door handle for a vehicle with a light-emitting device, including upper and lower housings. A through hole is provided on the upper housing, and a transparent upper housing insert is arranged in the through hole. A light-emitting module is installed between the upper and lower housings, and a layer of light-impermeable electroplated layer is plated on the surface of the upper housing.

[0005] In the above two patent documents, the light-emitting element or the light-emitting module is installed in the cavity formed between the light-transmitting plate and the housing, or between the lower housing and the upper housing. Since the problem of sealing the cavity is not solved, dust and water are likely to enter the cavity from the tiny gaps between the light-transmitting plate and the housing, or between the lower housing and the upper housing, forming water stains and dirt on the surface of the light-emitting element or the light-emitting module, thereby affecting the brightness of the light emitted from the door handle, and it is also easy to damage the circuit board of the light-emitting element or the light-emitting module, without forming reliable protection for the light-emitting element or the light-emitting module. Summary of the Invention

[0006] The purpose of the present invention is to provide an externally-opening and light-emitting handle for vehicles, which can effectively prevent dust and water from entering the handle and affecting the brightness of the light emitted by the LED lamp, and effectively protect the circuit board of the LED lamp.

[0007] The vehicle exterior-opening luminous handle described in the present invention includes a handle base, an LED lamp installed in the handle base, and a handle cover with a light-transmitting area and fixed to the port of the handle base. The LED lamp includes a lamp base, a light-transmitting plate, and a light source integrated circuit board. The light source integrated circuit board is located inside the lamp base. The light-transmitting plate is fixed to the port of the lamp base to encapsulate the light source integrated circuit board inside the lamp base. A sealing strip is provided along the edge of the upper surface of the light-transmitting plate. The handle cover presses against the sealing strip. On both sides and one end of the port of the handle base, bosses are provided along the inner edge of the port. There is no such boss at the other end of the port of the handle base. A second clamping platform is provided outside the boss. A third clamping platform is provided at a position corresponding to the second clamping platform on the inner side of the port of the handle cover. The handle cover is clamped and fastened to the port of the handle base through the third clamping platform and the second clamping platform.

[0008] Elastic clamping feet are provided at the lower parts on both outer sides of the lamp base. First clamping platforms are provided at positions corresponding to the elastic clamping feet on both inner sides of the handle base. The elastic clamping feet are clamped and hooked on the first clamping platforms.

[0009] Elastic clips are provided on the bosses on both sides of the port of the handle base. Wedge-shaped clips are provided at positions corresponding to the elastic clips on the inner side of the port of the handle cover. The wedge-shaped clips are clamped with the elastic clips.

[0010] During assembly, first place the LED lamp into the handle base, and make the wire harness of the LED lamp pass through the wire harness hole at the bottom surface of the handle base. Press down the LED lamp to make the elastic clamping feet on both sides of the lamp base of the LED lamp be clamped on the first clamping platforms on both sides of the handle base. Then place the handle cover on the port of the handle base, and make one end of the handle cover extend out of the corresponding end of the handle base (that is, the two ends of the handle cover and the two ends of the handle base are not aligned first, so that the third clamping platform on the handle cover and the second clamping platform on the handle base are staggered in the vertical direction). Press down and push the handle cover towards the handle base to make the third clamping platform and the second clamping platform be clamped, and at the same time the wedge-shaped clip on the handle cover is also clamped with the elastic clip on the handle base. At this time, the two ends of the handle cover and the two ends of the handle base are aligned, so as to realize the clamping and fastening of the handle cover on the handle base, and then the luminous handle can be assembled with the door handle assembly.

[0011] In the present invention, the LED light of the LED lamp emits from the light-transmitting plate. Since a sealing strip is provided along the edge of the upper surface of the light-transmitting plate, after the handle cover is clamped and fastened to the handle base, the handle cover will press against the sealing strip, thus forming a good seal for the light-transmitting plate. The water and dust entering the handle through the gap between the handle cover and the handle base will not adhere to the light-transmitting plate, so it will not affect the brightness of the light emitted by the LED lamp. And because the light source integrated circuit board of the LED lamp is encapsulated between the lamp base and the light-transmitting plate, the water and dust entering the handle will not affect the light source integrated circuit board either, so that the circuit board of the LED lamp can be effectively protected.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 8 As shown, the vehicle-use outward-opening luminous handle comprises a handle seat 2, a handle cover 1 and an LED lamp 3. Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the LED lamp 3 includes a lamp holder 31, a light-transmitting plate 34 and a light source integrated circuit board 35. The lamp holder 31 includes four side plates and a bottom plate, so that the lamp holder 31 forms a port. The light source integrated circuit board 35 is located in the lamp holder 31, and its wiring harness 33 passes through the bottom plate of the lamp holder 31. The light-transmitting plate 34 is fixed to the port of the lamp holder 31 by gluing or welding, and the light source integrated circuit board 35 is encapsulated in the lamp holder 31. A circle of sealing strips 32 are arranged along the edge of the upper surface of the light-transmitting plate 34. The sealing strips 32 are integrated with the light-transmitting plate 34 by a two-color injection molding process. An elastic clamping foot 36 is arranged at each of the lower parts of the two outer sides of the lamp holder 31.

[0022] like Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, on both sides and one end of the port of the handle base 2, there are bosses 22 provided along the inner edge of the port. There is no such boss 22 at the other end of the port of the handle base 2. On the outside of the boss 22, there are multiple second latches 21 provided. On the bosses 22 on both sides of the port of the handle base 2, there is also one elastic clip 23 provided respectively. On the lower parts of both inner sides of the handle base 2, at positions corresponding to the elastic feet 36, there is one first latch 25 provided respectively.

[0023] As Figure 3 and Figure 8 shown, on the inner side of the port of the handle cover 1, at positions corresponding to the second latches 21, there are multiple third latches 12 provided. On the inner side of the port of the handle cover 1, at positions corresponding to the elastic clips 23, there is one wedge-shaped clip 13 provided respectively. The handle cover 1 is injection molded from a light-transmissive plastic material (PC type material). On the handle cover 1, there is a long strip-shaped light-transmissive area 11 provided. Its surface appearance processing technology is as follows: First step, first spray the entire outer surface of the handle cover 1 with the required color (the same as the body color); Second step, use a laser engraving device to etch away the paint on the surface of the long strip-shaped light-transmissive area 11; Third step, after the surface of the handle cover 1 is cleaned, spray a layer of transparent paint to protect the surface of the long strip-shaped light-transmissive area 11 and the etched edge of the corresponding paint on the edge.

[0024] As Figure 7 and Figure 8 shown, the LED lamp 3 is located inside the handle base 2. The two elastic feet 36 on the lamp base 31 are clamped and hooked on the two first latches 25 on the handle base 2, thereby fixing the LED lamp 3 inside the handle base 2. The wire harness 33 of the LED lamp 3 passes through the wire harness hole 24 at the bottom surface of the handle base 2. The multiple third latches 12 on the handle cover 1 are clamped with the multiple second latches 21 on the handle base 2, so that the handle cover 1 is clamped and buckled on the port of the handle base 2. The handle cover 1 presses against the sealing strip 32 of the light-transmissive plate 34, forming extrusion on the sealing strip 32, thereby forming a seal for the light-transmissive plate 34. And the reaction force of the sealing strip 32 on the handle cover 1 can also increase the clamping force between the third latch 12 and the second latch 21, thereby reliably fixing the handle cover 1 on the port of the handle base 2. At the same time, the two wedge-shaped clips 13 on the handle cover 1 are clamped with the two elastic clips 23 on the handle base 2, which can prevent the handle cover 1 from loosening along the length direction of the handle base 2.

[0025] During assembly, first place the LED lamp 3 into the handle base 2, and let the wire harness 33 of the LED lamp 3 pass through the wire harness hole 24 at the bottom surface of the handle base 2. Press down the LED lamp 3 to make the elastic feet 36 on both sides of the lamp socket of the LED lamp 3 snap onto the first clamping platforms 25 on both sides of the handle base 2. Then, snap the handle cover 1 onto the port of the handle base 2, and make one end of the handle cover 1 extend beyond the corresponding end of the handle base 2 (that is, the two ends of the handle cover 1 and the two ends of the handle base 2 are not aligned first, so that the third clamping platform 12 on the handle cover 1 and the second clamping platform 21 on the handle base 2 are staggered in the vertical direction). Press down and push the handle cover 1 towards the handle base 2 to make the third clamping platform 12 and the second clamping platform 21 engage, and at the same time, the wedge-shaped clip 13 on the handle cover 1 also engages with the elastic clip 23 on the handle base 2. At this time, the two ends of the handle cover 1 and the two ends of the handle base 2 are aligned, thus realizing the snap-fastening of the handle cover 1 on the handle base 2, and then the luminous handle can be assembled with the door handle assembly.
