Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and more specifically, to a lighting device, a vehicle lamp, and a vehicle. Background Art

[0002] The support plane connecting the lens module to the lamp body of a traditional headlight is typically not positioned near the lens module's center of mass. Furthermore, due to space constraints within the lamp body, the rearward portion of the center of mass plane (the plane where the center of mass lies) cannot be enlarged, while the forward portion cannot be reduced due to the design requirements of the headlight. This misalignment between the lens module's support plane and the center of mass plane can generate a significant moment of inertia (mass moment of inertia) during vehicle testing or driving, causing the lens module to twist. The combined impact of vibration acceleration and the twisting force of the lens module can further damage the lamp body's mounting structure and dimming mechanism, leading to structural failure.

[0003] Therefore, how to reduce the large moment of inertia caused by the deviation of the center of mass plane from the support plane and improve the reliability of the headlights has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0016] Optionally, in the above-mentioned lighting device, the lens module also includes a decorative frame, which limits a mounting cavity for accommodating the inner lens, and the inner lens is located in the mounting cavity. The inner lens has a light input end and a light output end that are relatively arranged, and the light input end of the inner lens is fixed to the mounting plate of the radiator by a fastener, so that the light emitted by the lamp board is emitted through the light input end and the light output end of the inner lens.

[0030] The core of this application is to provide a lighting device to reduce the large moment of inertia caused by the deviation of the center of mass plane from the support plane, thereby improving the reliability of the vehicle lamp.

[0031] Another core of the present application is to provide a vehicle lamp having the above-mentioned lighting device.

[0032] Another core of the present application is to provide a vehicle having the above-mentioned headlight.

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The support plane connecting the lens module to the lamp body of a traditional headlight is typically not positioned near the lens module's center of mass. Furthermore, due to space constraints within the lamp body, the rearward portion of the center of mass plane (the plane where the center of mass lies) cannot be enlarged, while the forward portion cannot be reduced due to the design requirements of the headlight. This misalignment between the lens module's support plane and the center of mass plane can generate a significant moment of inertia (mass moment of inertia) during vehicle testing or driving, causing the lens module to twist. The combined impact of vibration acceleration and the twisting force of the lens module can further damage the lamp body's mounting structure and dimming mechanism, leading to structural failure.

[0035] For this reason, Figure 1 As shown, the embodiment of the present application discloses a lighting device comprising a lens module 100 and a mass module 200. The time difference created by the buffering effect of the resetting elastic member 203 effectively mitigates the impact force, transforming a rigid impact into a flexible impact. This reduces the impact and damage to the dimming mechanism caused by the impact force of vibration acceleration and the torsional force of the lens module 100, thereby improving the reliability of the vehicle lamp. Furthermore, the effect of the lamp housing vibration on the lens module 100 is weakened or isolated, thereby optimizing the light pattern jitter caused by torsional movement, improving visual perception and safety.

[0036] The following will be combined Figures 1 to 5 The lighting device disclosed in the embodiments of the present application is specifically explained and illustrated.

[0037] like Figure 1 As shown, the mass module 200 includes a connecting frame 201 and a load-bearing member 202, and the difference between the mass of the load-bearing member 202 and the mass of the lens module 100 is greater than a preset value, where the preset value can be determined by those skilled in the art based on actual conditions. At the same time, the connecting frame 201 is rigidly connected to the rear of the lens module 100, and the load-bearing member 202 is connected to the connecting frame 201 via a return spring 203. Multiple return springs 203 can be used, and each return spring 203 is symmetrically distributed on the side of the load-bearing member 202, so that the load-bearing member 202, under the elastic force of the return spring 203, balances the rotational inertia generated by the lens module 100. When acceleration is applied in one direction, the return spring 203 causes the load-bearing member 202 to compress in the opposite direction, acting as an energy storage device. This energy is then released upon the next reverse acceleration to balance the moment of inertia caused by the center of mass deviating from the support plane, creating a time difference between the maximum amplitude point and the maximum force point. This effectively mitigates the impact force, reduces the impact and damage to the dimming mechanism caused by the impact force of the vibration acceleration and the torsional force of the lens module 100, and improves the reliability of the vehicle lamp. At the same time, due to the significant difference between the mass of the load-bearing member 202 and the mass of the lens module 100, their natural frequencies differ significantly. During vibration, their vibration frequencies cancel each other out, thereby weakening or isolating the effect of the lamp housing's vibration on the lens module 100. This, in turn, optimizes the light pattern jitter caused by torsion, improving visual perception and safety. It should be noted that the return spring 203 can be a compression spring, for example.

[0038] For ease of understanding, the fixed position of the center of mass of the lens module 100 and the mass module 200 is defined as W1. When the reset elastic member 203 is compressed and released by acceleration, the load-bearing member 202 is displaced. At this time, the center of mass position of the lens module 100 and the mass module 200 changes dynamically. The dynamic position of the center of mass of the lens module 100 and the mass module 200 is defined as W2. When the lens module 100 is accelerated in one direction, the reset elastic member 203 causes the load-bearing member 202 to be compressed in the opposite direction, thereby storing energy. Then, when the next reverse acceleration arrives, the stored energy is released to balance the moment of inertia caused by the center of mass deviating from the support plane. Under actual working conditions, there is a positive and negative switching of acceleration in any vibration impact. When the acceleration is positive, W2 is away from W1; when the acceleration is negative, W2 is close to W1, so that W2 deviates from W1 to varying degrees under the action of different accelerations, and the position of W2 is on the side that is favorable to the impact. At the same time, the action of the resetting elastic member 203 creates a certain time difference between the point of maximum amplitude and the point of maximum force. The combined effects of this center of mass shift and time difference effectively mitigate impact forces, reducing the impact and damage to the dimming mechanism caused by the impact of vibration acceleration and the torsional force of the lens module 100, thereby improving the reliability of the vehicle lamp. Furthermore, due to the significant difference in mass between the load-bearing member 202 and the lens module 100, their natural frequencies differ significantly. During vibration, these frequencies cancel each other out, thereby weakening or isolating the impact of the lamp housing vibration on the lens module 100. This, in turn, optimizes the light pattern jitter caused by torsional forces, improving visual perception and safety.

[0039] like Figure 4 and Figure 5 As shown, the lens module 100 includes an outer lens 101, an inner lens 102 and a light source module 103, wherein the inner lens 102 is located between the outer lens 101 and the light source module 103, so that the light emitted by the light source module 103 can be emitted through the inner lens 102 and the outer lens 101 in sequence.

[0040] In some embodiments, as Figure 5As shown, the light source module 103 may include a heat sink 1031 and a light board 1032 mounted on the heat sink 1031. The heat sink 1031 may include a mounting plate 1033 and a plurality of heat dissipating fins 1034. The light board 1032 may be secured to one side of the mounting plate 1033 via fasteners such as bolts. The heat dissipating fins 1034 may be spaced apart on a side of the mounting plate 1033 facing away from the light board 1032. For ease of understanding, two opposing sides of the mounting plate 1033 are defined as a first side and a second side, respectively. The light board 1032 may be mounted on the first side of the mounting plate 1033, and the heat dissipating fins 1034 may be spaced apart on the second side of the mounting plate 1033. Specifically, a mounting slot for mounting the light board 1032 is defined on the first side of the mounting plate 1033. The light board 1032 is positioned by means of positioning posts within the mounting slot and positioning holes on the light board 1032. The light board 1032 may be secured to the mounting slot of the mounting plate 1033 via fasteners such as bolts. In addition, the inner lens 102 has a light input end and a light output end that are relatively arranged, wherein the light input end of the inner lens 102 can be fixed to the first side surface of the mounting plate 1033 by fasteners such as bolts, so that the light emitted by the lamp board 1032 located in the mounting groove can be injected into the light input end of the inner lens 102 and emitted from the light output end of the inner lens 102.

[0041] In some embodiments, as Figure 4 and Figure 5 As shown, the lens module 100 may also include a module bracket 104, and the module bracket 104 has a second mounting opening 1041 for mounting the heat sink 1031. The module bracket 104 can be fixed to the mounting plate 1033 of the heat sink 1031 by fasteners such as bolts, so that each heat dissipation fin 1034 can pass through the second mounting opening 1041, thereby achieving a connection and fixation between the module bracket 104 and the heat sink 1031. At the same time, a dimming mechanism 1042 is provided on the module bracket 104, and the distance between the lens module 100 and the lamp housing can be adjusted by the dimming mechanism 1042. It should be noted that the specific structure of the dimming mechanism 1042 in this application is prior art and will not be described in detail herein.

[0042] In some embodiments, as Figure 4 and Figure 5As shown, in order to avoid light diffusion, the lens module 100 may also include a decorative frame 105, and the decorative frame 105 is formed with a mounting cavity 1051 for accommodating the inner lens 102. The inner lens 102 is located in the mounting cavity 1051. For ease of understanding, the two opposite ends of the decorative frame 105 are defined as a first end and a second end, respectively, and the first end of the decorative frame 105 can be fixed to the module bracket 104 by fasteners such as bolts, while the outer lens 101 can be plugged into the second end of the decorative frame 105 so that the light emitted from the light-emitting end of the inner lens 102 is emitted through the outer lens 101. Specifically, the first end of the decorative frame 105 is a large-mouth end, and the second end of the decorative frame 105 is a small-mouth end. Slots are provided on both sides of the second end of the decorative frame 105, and arms that cooperate with the slots are provided on both sides of the outer lens 101. A limit baffle is provided at the bottom of the outer lens 101. During installation, the outer lens 101 can be inserted into the installation cavity 1051 from the first end of the decorative frame 105 and moved to the second end of the decorative frame 105, so that the arms on both sides of the outer lens 101 are inserted into the slots of the decorative frame 105. At the same time, the limit baffle at the bottom of the outer lens 101 abuts against the bottom wall of the first end of the decorative frame 105. At this time, the first end of the decorative frame 105 is fixed to the module bracket 104 by fasteners such as bolts, thereby realizing the assembly of the lens module 100.

[0043] In some embodiments, as Figure 2 and Figure 3 As shown, the connecting frame 201 is formed with a first mounting opening 2011 for mounting a load-bearing member 202. The load-bearing member 202 is located within the first mounting opening 2011 and can be connected to the sidewall of the first mounting opening 2011 via a resilient member 203. The load-bearing member 202 can have a circular cross-section, a square cross-section, or the like. The first mounting opening 2011 of the connecting frame 201 is compatible with the load-bearing member 202 and is larger than the load-bearing member 202. This allows the load-bearing member 202 to be compressed in the opposite direction when the lens module 100 is accelerated in one direction by the resilient member 203, thereby storing energy. This energy is then released when the next reverse acceleration occurs to balance the moment of inertia caused by the center of mass deviating from the support plane. The connecting frame 201 is also secured to the heat dissipation fins 1034 of the heat sink 1031 via fasteners such as bolts to facilitate assembly of the mass module 200 with the lens module 100.

[0044] In some embodiments, as Figure 2 and Figure 3As shown, the load-bearing member 202 can be of a square structure, and the connecting frame 201 and the first mounting opening 2011 formed by the connecting frame 201 both have a square cross-section that matches the load-bearing member 202. Mounting holes for connecting to the heat dissipation fins 1034 of the radiator 1031 are provided at the four corners of the first mounting opening 2011 to facilitate assembly with the lens module 100. Simultaneously, four resetting elastic members 203 can be provided, located at the four positions of the load-bearing member 202, one above, one below, one below, one below, one below, one below, one below, one below, one below, and one below, respectively, and connected to the load-bearing member 202 and the connecting frame 201. This allows the load-bearing member 202 to be compressed in the opposite direction by the resetting elastic members 203 when acceleration is applied to the lens module 100 in any direction, thereby storing energy. This energy is then released when the next reverse acceleration occurs to balance the moment of inertia caused by the center of mass deviating from the support plane. Of course, the number of resetting elastic members 203 can also be 8, 12, or more, i.e., two, three, or more resetting elastic members 203 can be provided at each position of the load-bearing member 202.

[0045] In some embodiments, as Figure 3 As shown, a first blind hole is defined at the center of the side of the load-bearing member 202, and a limiting post 2021 is disposed within the first blind hole. This allows one end of the reset elastic member 203 to be sleeved onto the limiting post 2021 and abut against the bottom wall of the first blind hole in the load-bearing member 202. The other end of the reset elastic member 203 is compressed to a preset position by a spring bracket 204 and secured to the connecting frame 201 via fasteners such as bolts. Specifically, a through hole is defined in the sidewall of the first mounting opening 2011 of the connecting frame 201, and the spring bracket 204 includes a mounting portion and connecting portions disposed on either side of the mounting portion. The mounting portion of the spring bracket 204 defines a second blind hole, within which a mounting post is disposed. During installation, one end of the reset elastic member 203 is sleeved on the limiting column 2021 of the load-bearing member 202 and abuts against the bottom wall of the first blind hole of the load-bearing member 202. The other end of the reset elastic member 203 can be sleeved on the mounting column and abuts against the bottom wall of the second blind hole. At the same time, the mounting portion of the spring bracket 204 can be extended into the through hole of the connecting frame 201 to compress the reset elastic member 203 to a preset position, and the two connecting portions of the spring bracket 204 are respectively fixed to both sides of the through hole of the connecting frame 201 by fasteners such as bolts to realize the assembly of the mass module 200. It should be noted that the reset elastic member 203 being compressed to the preset position in the above embodiment refers to the compressed position of the reset elastic member 203 when the load-bearing member 202 is at the center position of the first mounting opening 2011 of the connecting frame 201.

[0046] The lighting device provided in this application is constructed by rigidly connecting the connecting frame 201 of the mass module 200 to the rear of the lens module 100, and connecting the load-bearing member 202 of the mass module 200 to the connecting frame 201 via a reset elastic member 203. When acceleration is applied in one direction, the reset elastic member 203 compresses the load-bearing member 202 in the opposite direction, acting as an energy storage device. This stored energy is then released upon the next reverse acceleration to balance the moment of inertia caused by the center of mass deviating from the support plane. This creates a certain time difference between the point of maximum amplitude and the point of maximum force, effectively alleviating impact forces, reducing the impact and damage to the dimming mechanism caused by the impact force of vibration acceleration and the torsional force of the lens module 100, and improving the reliability of the vehicle lamp. At the same time, since the mass of the load-bearing member 202 is significantly different from the mass of the lens module 100, the natural frequencies of the two are significantly different. During the vibration process, the vibration frequencies of the two will cancel each other out, thereby weakening or isolating the impact of the vibration of the lamp housing on the lens module 100, and further optimizing the light pattern jitter caused by torsion, thereby improving visual perception and safety.

[0047] As can be seen from the above embodiments, the lighting device provided by this application effectively mitigates impact forces through the time difference created by the buffering effect of the resetting elastic member 203, transforming rigid impacts into flexible impacts. This reduces the impact and damage to the dimming mechanism caused by the impact force of vibration acceleration and the torsional force of the lens module 100, thereby improving the reliability of the vehicle lamp. Furthermore, the device can weaken or isolate the impact of lamp housing vibration on the lens module 100, thereby optimizing the light pattern jitter caused by torsional vibration, improving visual perception and safety.

[0048] The present application also discloses a vehicle lamp comprising a lamp housing and the lighting device described in the above embodiment. Therefore, the lighting device combines all the technical effects of the above lighting devices, which will not be described in detail herein. The lighting device is mounted within the lamp housing and can be connected and fixed to the lamp housing by fasteners such as bolts.

[0049] The embodiment of the present application also discloses a vehicle, including the headlights as described in the above embodiment. Therefore, the headlights have all the technical effects of the above-mentioned headlights, which will not be described in detail herein.
