Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a vehicle lamp with a shock-absorbing structure. Background Art

[0002] Car lights serve as a display structure for driving signals. The driver of the current vehicle can signal his driving intention through changes in the lights, and the drivers of other vehicles can make timely driving decisions based on the driving intentions signaled by other vehicles through their lights, thereby ensuring driving safety.

[0003] The existing car lamp structure is relatively simple, such as the LED car tail lamp disclosed in patent CN103423688A, which includes a lamp holder, a substrate is provided in the lamp holder, an LED light-emitting body is provided on the substrate, a light-transmitting cover is provided outside the LED light-emitting body, the light-transmitting cover is connected to the lamp holder, and a reflective cup is wrapped on the LED light-emitting body. When the LED light-emitting body is working, it emits light through the light-transmitting cover after being focused by the reflective cup. In addition, during assembly, the substrate is installed in the lamp holder and the light-transmitting cover and the reflective cup are installed on the lamp holder through a number of screws or buckles to form an integral car lamp, and then the assembled integral car lamp is installed on the car body. However, due to the vibration generated when the car is running, especially for some use occasions with complex road conditions, the electronic components inside the car lamp are very likely to be desoldered and damaged under vibration, and there is a problem of short service life. In addition, since the headlights are installed and used as an integral structure, there are many inconveniences in replacing the internal components during later maintenance of the headlights, which results in most cases requiring replacement of the headlights as a whole. Therefore, headlights with structural damage due to vibration will lead to increased later use costs and waste of resources. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 2 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0022] Figure 1FIG. 1 is a structural diagram of an embodiment of a vehicle lamp with a shock absorbing structure of the utility model. Figure 1 As shown, the vehicle lamp with a shock absorbing structure provided in this embodiment includes: a bottom shell 1, a circuit board 2, a reflective bowl 3 and a lampshade 4, and also includes a first shock absorbing pad 5, a combined frame 6 and a second shock absorbing pad 7.

[0023] Specifically, the bottom shell 1 has a concave cavity 11 with a side opening, and the circuit board 2 is installed in the concave cavity 11, that is, the concave cavity 11 provides installation space for electronic components such as the circuit board 2. In addition, a plurality of LED lamps 21 are distributed on the circuit board 2 according to a predetermined rule, and the plurality of LED lamps 21 are arranged toward the side opening of the concave cavity 11, which provides conditions for the subsequent use with the reflector 3 and the lampshade 4. At the same time, the reflector 3 is arranged at the side opening of the concave cavity 11, and the reflector 3 is provided with a plurality of light-gathering cavities 31 corresponding to the LED lamps 21, and the bottom of each light-gathering cavity 31 is provided with a socket, and the light-emitting part of each LED lamp 21 extends from the corresponding socket into the corresponding light-gathering cavity 31, so that the light energy emitted by the LED lamp is gathered through the light-gathering cavity 31, thereby increasing the brightness, ensuring the divergence direction of the light, and improving the performance. In addition, the lampshade 4 is arranged on the side opening of the concave cavity 11 of the bottom shell 1 and the side opening is sealed, so that the bottom shell 1 and the lampshade 4 can form a relatively closed space, thereby protecting the headlight and improving safety. In addition, a first shock-absorbing pad 5 is arranged between the circuit board 2 and the bottom shell 1. The first shock-absorbing pad 5 is used as a shock-absorbing structure after the circuit board 2 is installed to minimize the risk of structural damage caused by driving vibration and extend the service life of the headlight. In addition, a combined frame 6 is also arranged between the reflective bowl 3 and the circuit board 2. The reflective bowl 3 and the circuit board 2 are formed into an integral structure through the combined frame 6, so that the reflective bowl 3 and the circuit board 2 can form a relatively static structure, that is, even if vibration occurs later, the circuit board 2 and the reflective bowl 3 can also vibrate synchronously as a whole, avoiding the problem of collision damage caused by relative movement of the circuit board 2 and the reflective bowl 3, and further extending the service life of the headlight. In addition, when the circuit board 2 and the reflective bowl 3 are combined into a whole through the combined frame 6 and installed in the bottom shell 1, the combined frame 6 abuts against the bottom shell 1, and a second shock-absorbing pad 7 is arranged between the combined frame 6 and the bottom shell 1. The second shock-absorbing pad 7 can absorb energy and reduce shock to the overall structure formed by the circuit board 2 and the reflective bowl 3. Combined with the function of the first shock-absorbing pad 5, the overall shock absorption of the electronic components in the car light is achieved, the influence of driving vibration on them is reduced, the service life is extended, the use cost is reduced, and the waste of resources is avoided.

[0024] More specifically, the first shock-absorbing pad 5 arranged between the circuit board 2 and the bottom shell 1 and the second shock-absorbing pad 7 arranged between the combined frame 6 and the bottom shell 1 are both shock-absorbing sponges, which have good energy absorption and shock-absorbing effects and are light in weight, which is conducive to vehicle-mounted layout.

[0025] More specifically, the first shock-absorbing pad 5 is arranged in a plate shape, and a plurality of first shock-absorbing pads 5 are provided. At this time, a connecting hole 51 is opened on each first shock-absorbing pad 5, and the number of the connecting holes 51 is consistent with the number of connecting parts on the bottom shell 1. During subsequent installation, the first shock-absorbing pad 5 is laid on the part where the circuit board 2 contacts the bottom shell 1. At the same time, the locking screws for installing the circuit board 2 are passed through the connecting holes 51 and then threadedly locked with the connecting part on the bottom shell 1. That is, the first shock-absorbing pad 5 is used as an energy-absorbing and shock-absorbing structure at the connecting part between the circuit board 2 and the bottom shell 1 to reduce the impact of driving vibration.

[0026] Figure 2 This is a structural diagram of a combined frame of a preferred embodiment of the utility model. Figure 1 , Figure 2 As shown, the combined frame 6 used to connect the circuit board 2 and the reflective bowl 3 into an integral structure further comprises a first clamping plate 61, a second clamping plate 62 and a plurality of connecting columns 63. During installation, the first clamping plate 61 and the second clamping plate 62 are respectively installed on the outer edges of the circuit board 2 and the reflective bowl 3, and at the same time, the first clamping plate 61 and the second clamping plate 62 are respectively abutted against the opposite sides of the circuit board 2 and the reflective bowl 3, so that the circuit board 2 and the reflective bowl 3 can be confined between the first clamping plate 61 and the second clamping plate 62. Since the bottom of the focusing cavity 31 of the reflective bowl 3 abuts against the circuit board 2, the circuit board 2 and the reflective bowl 3 can be clamped by the first clamping plate 61 and the second clamping plate 62. In addition, a plurality of connecting columns 63 are disposed between the first clamping plate 61 and the second clamping plate 62 and the first clamping plate 61 and the second clamping plate 62 are tightened, so that the first clamping plate 61 and the second clamping plate 62 can form an integrated structure through the plurality of connecting columns 63, thereby clamping the circuit board 2 and the reflective bowl 3 to form an integral structure, thereby providing conditions for subsequently maintaining the relative stillness of the circuit board 2 and the reflective bowl 3.

[0027] More specifically, the first clamping plate 61 and the second clamping plate 62 of the combined frame 6 are both annular frame structures, which are convenient for being mounted on the outer edges of the circuit board 2 and the reflective bowl 3, and also avoid the problem that the first clamping plate 61 and the second clamping plate 62 affect the heat dissipation of the circuit board 2 and the divergence of the light on the reflective bowl 3. In addition, a concave embedding groove 611 is provided on the inner side wall of the first clamping plate 61 and the second clamping plate 62. At the same time, when the first clamping plate 61 and the second clamping plate 62 are installed on the corresponding circuit board 2 and the reflective bowl 3, the outer edges of the circuit board 2 and the reflective bowl 3 are respectively inserted into the embedding groove 611 of the first clamping plate 61 and the second clamping plate 62. Through the cooperation between the embedding groove 611 and the circuit board 2 and the embedding groove 611 and the outer edge of the reflective bowl 3, the first clamping plate 61 and the circuit board 2 and the second clamping plate 62 and the reflective bowl 3 are limited, so that the overall structure formed by the combined frame 6 can be more stable.

[0028] More specifically, the outer side edge of the first splint 61 is fixedly connected to one end of half the number of connecting columns 63, thereby realizing the overall arrangement of some connecting columns 63 and the first splint 61. Similarly, the outer side edge of the second splint 62 is fixedly connected to one end of the other half number of connecting columns 63, thereby realizing the overall arrangement of the remaining connecting columns 63 and the second splint 62. The number of fixed connecting columns 63 on the first splint 61 and the second splint 62 is equal. Preferably, when the first splint 61 and the second splint 62 are arranged relative to each other, the fixed connecting columns 63 on the first splint 61 and the second splint 62 are alternately staggered to ensure uniform force. At the same time, the other end of the connecting column 63 fixedly connected to the first clamping plate 61 is detachably connected to the second clamping plate 62, and the other end of the connecting column 63 fixedly connected to the second clamping plate 62 is detachably connected to the first clamping plate 61, so that the connecting column 63 fixedly connected on the first clamping plate 61 and the second clamping plate 62 can be disassembled, and similarly, the connecting column 63 fixedly connected on the second clamping plate 62 can also be disassembled from the first clamping plate 61, which facilitates the installation of the first clamping plate 61 and the second clamping plate 62 on the circuit board 2 and the reflective bowl 3, and the structural design is more reasonable.

[0029] More specifically, the detachable connection between the connecting column 63 and the first clamp plate 61 and the detachable connection between the connecting column 63 and the second clamp plate 62 are both snap-on connections. At this time, a snap foot 631 is provided at the end of the connecting column 63, and a snap hole 612 corresponding to the snap foot 631 is opened at a corresponding position on the first clamp plate 61 or the second clamp plate 62. The detachable connection between the connecting column 63 and the first clamp plate 61 and the connecting column 63 and the second clamp plate 62 is achieved by snapping the snap foot 631 into or out of the snap hole 612, thereby facilitating the disassembly and assembly of the combined frame 6.

[0030] More specifically, when the second shock-absorbing pad 7 disposed between the combined frame 6 and the bottom shell 1 is installed, the second shock-absorbing pad 7 is sleeved on the outer edges of the first clamping plate 61 and the second clamping plate 62, so that the second shock-absorbing pad 7 is installed on the combined frame 6, so that both ends of the combined frame 6 have energy-absorbing and shock-absorbing structures, and the shock-absorbing effect is better. Preferably, the second shock-absorbing ring is bonded to the combined frame 6, which is more convenient to install.

[0031] More specifically, the combined frame 6 is installed in the inner cavity of the bottom shell 1, and when the combined frame 6 is installed in place in the inner cavity, the outer side of the second shock-absorbing pad 7 abuts against the inner wall of the inner cavity, which can not only achieve the contact between the combined frame 6 and the bottom shell 1 and improve the installation stability, but also weaken the vibration transmitted from the bottom shell 1, further reduce the impact of driving vibration on the electronic components in the car lamp, and make the structural layout more reasonable.

[0032] More specifically, a third shock-absorbing pad is provided between the reflective bowl 3 and the circuit board 2. Preferably, the third shock-absorbing pad is made of rubber. Since the bottom of the focusing cavity 31 of the reflective bowl 3 rests on the circuit board 2, the third shock-absorbing pad can prevent the two from being directly pressed against each other and being damaged. The structural design is more reasonable and the service life is longer.

[0033] The vehicle lamp with a shock-absorbing structure provided in the present embodiment comprises a bottom shell 1, a circuit board 2, a reflective bowl 3, a lampshade 4, a first shock-absorbing pad 5, a combined frame 6 and a second shock-absorbing pad 7. The first shock-absorbing pad 5 is arranged between the circuit board 2 and the bottom shell 1. At the same time, the circuit board 2 and the reflective bowl 3 are first formed into an integral structure through the combined frame 6, and then the second shock-absorbing pad 7 is arranged between the combined frame 6 and the bottom shell 1. The first shock-absorbing pad 5 and the second shock-absorbing pad 7 are used to absorb energy and reduce shock for the integral structure formed by the circuit board 2 and the reflective bowl 3. At the same time, after the circuit board 2 and the reflective bowl 3 are formed into an integral structure through the combined frame 6, the circuit board 2 and the reflective bowl 3 can be in a relatively static state, thereby avoiding the problem of relative movement and collision between the circuit board 2 and the reflective bowl 3 caused by vibration generated during driving, thereby reducing the influence of driving vibration on electronic components in the vehicle lamp, extending the service life of the vehicle lamp, reducing the use cost of the vehicle lamp, and avoiding waste of resources.

[0034] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
