Description

Technical Field

[0001] The present application relates to the field of vehicle lighting technology, and in particular to a lamp and a vehicle. Background Art

[0002] With the development and progress of science and technology and people's higher and higher requirements on the use of cars, in addition to the requirements on car performance and styling, the details of car use are becoming more and more important.

[0003] People often encounter a problem when opening the trunk. After a heavy rain, the moment the trunk is opened, the accumulated water on the trunk lid where the headlights are located may flow into the trunk, causing items to get wet. This is the problem of water accumulation that needs to be avoided in the design of headlights. Therefore, how to avoid the problem of water accumulation on the surface of the headlight structure is also an issue that major car manufacturers pay close attention to.

[0004] On the other hand, in conventional designs, avoiding structures with grooves that are prone to water accumulation is a key step that must be considered during the design process. However, due to the complexity of headlight design, it is inevitable to set up groove structures in certain parts, so a drainage structure must be designed in conjunction. The drainage structure is an open structure and is likely to reduce the sealing performance of the lamp. Therefore, how to drain the water accumulated in this unavoidable groove structure is also a test of the professional level of designers. Utility Model Content

[0005] In order to solve the above problems, the technical solutions adopted in the embodiments of the present application are as follows:

[0006] A lamp, comprising:

[0007] A lamp body, used to accommodate the light-emitting element;

[0008] A light distribution mirror, the light distribution mirror is arranged on the light emitting side of the lamp body, and the outer periphery of the light distribution mirror is sealed and connected to the edge of the lamp body through a sealing structure, and the light distribution mirror is provided with a water passage at a position close to the edge, and the water passage is located at the periphery of the sealing structure;

[0009] The two ends of the water passage are respectively a water inlet end and a water outlet end, the water inlet end is located on the side of the photometric mirror away from the lamp body, and the distance between the water inlet end and the edge of the photometric mirror is smaller than the distance between the sealing structure and the edge of the photometric mirror, so as to allow the liquid gathered at the edge of the photometric mirror away from the lamp body to flow into the water passage;

[0010] The water outlet is located on a side of the light distribution mirror close to the lamp body and is configured to be opposite to a drainage channel of the vehicle, so as to allow the liquid in the water channel to flow to the side close to the lamp body and be discharged through the drainage channel.

[0011] In the present application, by designing a water flow channel on the light distribution mirror, the liquid gathered on the surface of the light distribution mirror away from the lamp body can flow from the periphery of the sealing structure at the edge of the light distribution mirror into the outer water flow channel and flow to the side close to the lamp body, and then be discharged from the drainage channel of the vehicle itself, thereby preventing water accumulation on the surface of the light distribution mirror.

[0012] The periphery of the photometric lens is sealed and connected to the edge of the lamp body through a sealing structure. Since the distance between the water inlet end and the edge of the photometric lens is smaller than the distance between the sealing structure and the edge of the photometric lens, the liquid gathered at the edge of the photometric lens will naturally flow to the water inlet end closer to the edge and will not easily flow to the sealing structure; moreover, the designed water passage is located at the periphery of the sealing structure, which greatly reduces the probability of the liquid flowing in the water passage contacting the sealing structure, so that the liquid cannot flow into the cavity between the lamp body and the photometric lens, so that the lamp can maintain a long-lasting good sealing performance.

[0013] As an optional implementation, in the embodiment of the present application, there are multiple groups of water passages, and the multiple groups of water passages are arranged at intervals and distributed on the periphery of the sealing structure.

[0014] As an optional implementation, in the embodiment of the present application, the six water passages are concentrated into a group.

[0015] As an optional implementation, in the embodiment of the present application, there are multiple water passages, which are sequentially arranged along the extension direction of the edge of the light distribution mirror;

[0016] The cross section of the water passage is an isosceles right triangle, and the adjacent side edges of every two adjacent water passages are parallel to each other, and the lengths of every two adjacent adjacent side edges are the same.

[0017] As an optional implementation, in the embodiment of the present application, the cross-section of the water passage is triangular.

[0018] As an optional implementation, in the embodiment of the present application, the radius R of the inscribed circle of the water passage is 1.5 mm-2.5 mm.

[0019] As an optional implementation, in the embodiment of the present application, the drainage channel of the vehicle is arranged at the periphery of the edge of the lamp body, and the drainage channel is integrally formed with the lamp body.

[0020] As an optional implementation, in the embodiment of the present application, the height of the sealing structure is greater than the height of the water inlet end, and the water inlet end is located at the lowest point of the surface of the light distribution mirror away from the lamp body.

[0021] As an optional implementation, in the embodiment of the present application, a clamping rib is provided on one side of the light distribution mirror close to the lamp body, a clamping groove is provided on the edge of the lamp body, the clamping rib is engaged with the clamping groove, and the clamping groove is filled with sealant.

[0022] A means of transport, comprising the lamp described in any one of the above items;

[0023] The lamp is connected between the windshield and the hood of the vehicle, and the front edge height of the lamp is lower than the rear end height of the hood, so as to form a low-lying concave portion where the front of the lamp is connected to the hood; alternatively, the lamp is arranged above the trunk of the vehicle.

[0024] When the lamp of the present application is arranged between the windshield and the hood of a car as a light projection lamp group, or is arranged above the trunk of a car as a taillight, the accumulated water on the surface of the photosensitive mirror can flow from the outer periphery of the sealing structure at the lower edge into the outer water passage, and then be discharged from the vehicle's own drainage channel, thereby avoiding water accumulation on the surface of the light projection lamp group behind the hood, which makes cleaning difficult, or water accumulation at the position of the headlight above the trunk lid of the car. When the hood or trunk is opened, no water will flow into the engine compartment or trunk to cause damage to components.

[0025] The periphery of the light distribution mirror of the lamp is sealed and connected to the edge of the lamp body through a sealing structure. Since the distance between the water inlet end and the lower edge of the light distribution mirror is smaller than the distance between the sealing structure and the lower edge of the light distribution mirror, the liquid gathered at the lower edge of the light distribution mirror under the action of gravity will naturally flow to the water inlet end closer to the edge and will not easily flow to the sealing structure; moreover, the water passage is located at the periphery of the sealing structure, which greatly reduces the probability of the liquid flowing in the water passage contacting the sealing structure, so that the liquid cannot flow into the cavity between the lamp body and the light distribution mirror, so that the lamp maintains a long-lasting good sealing performance.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] As described in the background technology, the emergence of interactive lamps can convey more information to vehicles or pedestrians, but it also brings higher energy consumption. At a time when battery life is emphasized, how to balance the relationship between interactive effects and power consumption is a difficult problem that needs to be solved urgently.

[0051] In order to solve the above problems, the present application provides a lamp, referring to Figure 1 and Figure 7 ,include:

[0052] The lamp body 100 is used to accommodate the light-emitting element;

[0053] A photometric mirror 200, wherein the photometric mirror 200 is disposed on the light-emitting side of the lamp body 100 and the periphery of the photometric mirror 200 is sealed and connected to the edge of the lamp body 100 via a sealing structure 400, and the photometric mirror 200 is provided with a water passage 210 at a peripheral portion near the edge, and the water passage 210 is located at the periphery of the sealing structure;

[0054] The two ends of the water passage 210 are respectively a water inlet end 211 and a water outlet end 212, the water inlet end 211 is located at a side of the photometric lens 200 away from the lamp body 100, and the distance between the water inlet end 211 and the edge of the photometric lens 200 is smaller than the distance between the sealing structure 400 and the edge of the photometric lens 200, so as to allow the liquid gathered at the edge of the photometric lens 200 away from the lamp body to flow into the water passage 210;

[0055] The water outlet 212 is located on a side of the light distribution mirror close to the lamp body 100 and is configured to be opposite to the drainage channel 300 of the vehicle, so as to allow the liquid in the water channel 210 to flow to the side close to the lamp body 100 and be discharged through the drainage channel 300 .

[0056] Specifically, the light-emitting element in the lamp body 100 emits light toward the light distribution mirror 200 on the light-emitting side, and the light distribution mirror 200 faces the outside of the lamp. After being dimmed by the light distribution mirror 200, the light is emitted outward from the side of the light distribution mirror 200 away from the lamp body 100. In the present application, by designing a water passage 210 on the light distribution mirror 200, the liquid gathered on the surface of the side of the light distribution mirror 200 away from the lamp body 100 can flow from the periphery of the sealing structure 400 at the edge of the light distribution mirror 200 into the peripheral water passage 210 and flow to the side close to the lamp body 100, and then be discharged from the drainage channel 300 of the vehicle itself, thereby preventing water from accumulating on the surface of the light distribution mirror 200.

[0057] The periphery of the photometric lens 200 is sealed and connected to the edge of the lamp body 100 through the sealing structure 400. Since the distance between the water inlet end 211 and the edge of the photometric lens 200 is smaller than the distance between the sealing structure 400 and the edge of the photometric lens 200, the liquid gathered at the edge of the photometric lens will naturally flow more easily to the water inlet end 211 closer to the edge and will not easily flow to the sealing structure 400; moreover, the designed water passage 210 is located at the periphery of the sealing structure 400, which greatly reduces the probability of the liquid flowing in the water passage 210 contacting the sealing structure 400, so that the liquid cannot flow into the cavity between the lamp body 100 and the photometric lens 200, so that the lamp can maintain a long-lasting good sealing performance.

[0058] refer to Figure 1 In some embodiments, there are multiple groups of water passages 210 , and the multiple groups of water passages 210 are arranged at intervals and distributed around the periphery of the sealing structure 400 .

[0059] Multiple groups of water channels 210 can increase the drainage volume per unit time and improve the drainage speed; the multiple groups of water channels 210 distributed at intervals have a good drainage effect on different positions of the edge of the lens 200, ensuring the consistency of the drainage effect of various parts of the periphery of the lens 200.

[0060] Preferably, at least six of the water passages 210 form a group, which can ensure that the location has a stronger drainage capacity.

[0061] refer to Figure 2 or Figure 3 In the embodiment, there are a plurality of water passages 210, which are sequentially arranged along the extension direction of the edge of the light distribution lens 200; the cross section of the water passage 210 is an isosceles right triangle, and the adjacent side edges 213 of every two adjacent water passages 210 are parallel to each other. Specifically, the cross section of the water passage 210 is arranged in the form of an isosceles right triangle in the present application, and the adjacent side edges 213 of every two adjacent water passages 210 are designed to be parallel to each other, and the lengths of every two adjacent adjacent side edges 213 are the same. When this arrangement is adopted, the number of water passages can be increased, especially when the adjacent side edges 213 of two adjacent water passages 210 are the hypotenuses of the isosceles right triangle, the projections of the two adjacent water passages 210 in the X direction perpendicular to the edge of the light distribution lens partially overlap, and the arrangement density of the water passages is further increased. Therefore, in this embodiment, when the value of the radius R of the inscribed circle of the water passage 210 is limited and unchanged, the maximum number of water passages 210 can be placed within a unit extension length L along the edge of the light distribution mirror 200, which is beneficial to further increase the drainage volume per unit time and speed up the drainage speed. It is particularly suitable for weather environments with heavy precipitation such as heavy rain, and is of great significance for broadening the usage scenarios.

[0062] refer to Figure 2 In some embodiments, the cross-section of the water passage 210 is triangular.

[0063] Compared with the water passage 210 with arc-shaped edges, the triangular water passage 210 can form multiple acute angles. The space at the corners is sharp and narrow, which can block debris (such as fallen leaves, pine cones, etc.) from entering the water passage 210 from the water inlet end 211, increasing the resistance and difficulty of the flow of debris. According to tests, it can effectively prevent debris from entering through the water inlet end 211 and blocking the water passage 210.

[0064] Of course, in some other embodiments, the cross section of the water passage 210 may also be Figure 4 and Figure 5The square in Figure 6 There is no restriction on other shapes such as hexagon.

[0065] refer to Figure 2 and Figure 3 In some embodiments, the inscribed circle radius R of the water passage 210 is 1.5 mm-2.5 mm. After professional evaluation and design, the inscribed circle radius R of the water passage 210 is selected in the range of 1.5 mm-2.5 mm to achieve the normal flow of accumulated water through the water passage 210. At the same time, the inscribed circle radius R is set to be smaller in size to block debris (such as fallen leaves, pine cones, etc.) and prevent debris from blocking the water passage 210. More preferably, the inscribed circle radius R of the water passage 210 is 2.0 mm. The radius R of 2.0 mm can ensure a high drainage speed and prevent debris from entering the water passage 210.

[0066] refer to Figure 7 In some embodiments, the drainage channel 300 of the vehicle is disposed at the periphery of the edge of the lamp body 100 , and the drainage channel 300 is integrally formed with the lamp body 100 .

[0067] Specifically, the drainage channel 300 of the vehicle is integrally formed with the lamp body 100 to avoid an assembly gap between the two during assembly that would reduce the sealing effect; and, the drainage channel 300 is arranged on the periphery of the edge of the lamp body 100 to prevent water in the drainage channel 300 from entering the cavity between the lamp body 100 and the light distribution lens 200.

[0068] refer to Figure 7 In some embodiments, the height of the sealing structure 400 is greater than the height of the water inlet end 211 , and the water inlet end 211 is located at the lowest point of the surface of the side of the photometric lens 200 away from the lamp body 100 .

[0069] In this embodiment, the water inlet end 211 is arranged at the lowest point of the surface of the side of the light distribution mirror 200 away from the lamp body 100, so that rainwater will directly gather at the water inlet end 211 at the edge of the light distribution mirror, and directly drain the water in the low-lying areas where water is easily accumulated, ensuring that all the water on the upper surface of the light distribution mirror 200 can be cleared; at the same time, it can be seen that Figure 7 The sealing structure 400 on the middle left side has a height greater than that of the water inlet end 211 , and the liquid tends to flow toward the lower water inlet end 211 , thereby preventing the liquid from entering the sealing structure 400 and damaging the seal.

[0070] refer to Figure 7In some embodiments, a clamping rib 410 is provided on a side of the photometric lens 200 close to the lamp body 100, a clamping groove 420 is provided on the edge of the lamp body 100, the clamping rib 410 is engaged with the clamping groove 420, and the clamping groove 420 is filled with sealant. Specifically, after the clamping rib 410 is engaged with the clamping groove 420, the photometric lens 200 and the lamp body 100 can be firmly connected by filling the sealant in the clamping groove 420, and good sealing between the photometric lens 200 and the lamp body 100 can be ensured to prevent water vapor, air, etc. from entering the interior of the lamp to damage electronic components.

[0071] refer to Figure 8 and Fig. 9 The present application also discloses a vehicle, comprising the lamp 10 in any of the aforementioned embodiments.

[0072] The above-mentioned means of transportation may be a car, a train, a high-speed train or other means of transportation that requires headlights.

[0073] For example, a lamp 10 with a light projection function may be connected between the wiper 21 of the front windshield 20 of the vehicle and the hood 30, and the front of the lamp 10 is tilted downward. In order to meet the angle requirement of the projected light, the height of the front edge of the lamp 10 needs to be lower than the rear end height of the hood 30. In this case, a low-lying depression will form where the front of the lamp 10 is connected to the hood and water will accumulate. However, the present application sets a water passage 210 near the front lower edge of the lamp 10, and the water passage 210 is located at the periphery of the lamp sealing structure 400; and at this time, the distance between the water inlet end 211 of the water passage 210 and the front edge of the light distribution mirror 200 is less than the distance between the sealing structure 400 and the front edge of the light distribution mirror 200. After getting caught in the rain, the accumulated water on the surface of the lens 200 can flow from the periphery of the sealing structure 400 at the front edge into the outer water passage 210, and then be discharged from the vehicle's own drainage channel 300, thereby avoiding water accumulation on the surface of the projection lamp 10 behind the hood 30, which makes it difficult to clean. When the hood 30 is opened, no water will enter the engine compartment to cause damage to components.

[0074] In another embodiment, the lamp of the present application can be placed above the trunk of a car and used as a taillight. In this case, a water passage 210 is provided at a position of the lamp close to the trunk lid and close to the lower edge, and the water passage 210 is located outside the sealing structure 400; and in this case, the distance between the water inlet end 211 of the water passage 210 and the lower edge of the photometric mirror is smaller than the distance between the sealing structure 400 and the lower edge of the photometric mirror. After being caught in the rain, the accumulated water on the surface of the photometric mirror 200 can flow from the outer periphery of the sealing structure 400 at the lower edge into the outer water passage 210, and then be discharged from the drainage channel 300 of the vehicle itself, thereby avoiding water accumulation at the position of the headlight above the trunk lid of the car, and when the trunk is opened, no water will flow into the trunk to wet the items, thereby avoiding the problem of water accumulation above the trunk.

[0075] The periphery of the light distribution mirror 200 of the lamp is sealed and connected to the edge of the lamp body 100 through the sealing structure 400. Since the distance between the water inlet end 211 and the lower edge of the light distribution mirror 200 is smaller than the distance between the sealing structure 400 and the lower edge of the light distribution mirror 200, the liquid gathered at the lower edge of the light distribution mirror under the action of gravity will naturally flow to the water inlet end 211 closer to the edge and will not easily flow to the sealing structure 400; moreover, the water passage 210 is located at the periphery of the sealing structure 400, which greatly reduces the probability of the liquid flowing in the water passage 210 contacting the sealing structure 400, so that the liquid cannot flow into the cavity between the lamp body 100 and the light distribution mirror 200, so that the lamp maintains a long-lasting and good sealing performance.

[0076] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0077] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
