Description

Technical Field

[0001] This application belongs to the field of automotive lighting, and particularly relates to an automotive lamp. Background Technology

[0002] When a vehicle is in a high-humidity environment (such as rainy or foggy weather, or after a car wash) or experiences drastic temperature changes (such as a cold start in winter or the transition between day and night), the air inside the headlights drops sharply to the dew point, causing water vapor to condense into a fine mist layer on the inner wall of the transparent cover. This phenomenon not only causes light scattering, significantly reducing illumination brightness and penetration distance, but may also create localized light spot distortion, interfering with the driver's judgment of road conditions.

[0003] Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this application is to provide an automotive lamp to solve the problem of water vapor condensation inside the existing automotive lamp.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide an automotive lamp, comprising:

[0006] Mounting plate;

[0007] A transparent cover is attached to the mounting plate and forms a first receiving cavity in conjunction with the mounting plate;

[0008] A housing is disposed within the first accommodating cavity and connected to the mounting plate, the housing forming a second accommodating cavity and an air inlet and an air outlet respectively connected to the second accommodating cavity;

[0009] A light source is disposed within the first receiving cavity and used for illumination;

[0010] The instant heating component is disposed within the second receiving cavity and has a blower capable of blowing air toward the air outlet and a heating device for generating heat. The heating device is disposed between the blower and the air outlet and is located in the air blowing path of the blower.

[0011] Compared with the prior art, the beneficial effects of the automotive lamp in this application are as follows: In the automotive lamp of this application, the first receiving cavity formed by the transparent cover and the mounting plate is used not only to accommodate the light source, but also to accommodate the housing and the instant heating component disposed in the second receiving cavity on the housing. Since the housing is provided with an air inlet and an air outlet, and since the heating device capable of generating heat is disposed between the air inlet and the air outlet, when the air blower blows air towards the air outlet, the heat generated by the heating device can be effectively transferred to the first receiving cavity. This can not only eliminate the water mist that has already condensed on the transparent cover, but also effectively prevent new water mist from condensing on the transparent cover. Therefore, the automotive lamp provided in this application can eliminate the problem of water mist condensation inside the lamp, which is far superior to the prior art.

[0012] Optionally, the blowing device includes a motor and a rotating blade; the motor forms an output shaft with its axis parallel to the direction of the air outlet, and the rotating blade is coaxially connected to the output shaft and can be driven to rotate by the output shaft. The air inlet and the air outlet are located on both sides of the rotating blade along the axial direction of the output shaft. In this solution, by setting the motor with its output shaft parallel to the direction of the air outlet and the rotating blade coaxially connected to the output shaft, the blowing direction of the blowing device can be made parallel to the direction of the air outlet. In this way, the blowing device can deliver the heat generated by the heating device to the first receiving cavity to the greatest extent, thereby further improving the anti-fog effect of the automotive lights in this application.

[0013] Optionally, at least two heating devices are evenly distributed around the output shaft. This solution, by setting at least two heating devices evenly distributed around the output shaft, can both increase the overall heat generation of the instantaneous heating component and make fuller use of the airflow generated by the blowing device, thus further improving the anti-fog effect of the automotive lights in this application.

[0014] Optionally, the instant heating component further includes a limiting block disposed within the second receiving cavity and connected to the housing; the limiting block abuts against opposite sides of the motor so that the center of gravity of the housing is located on the central axis of the output shaft. In this solution, by providing a limiting block for limiting the motor in the second receiving cavity, the axial direction of the output shaft can pass through the center of gravity of the housing, thus making fuller use of the airflow generated by the blowing device, thereby further improving the anti-fog effect of the automotive lights in this application.

[0015] Optionally, the automotive lamp further includes a support assembly; the support assembly includes a cylinder and a support plate spaced apart in the first receiving cavity, a sliding plate connected to the power end of the cylinder, and a mounting rod connected to the housing. The output direction of the cylinder is towards the support plate and can drive the sliding plate closer to or away from the support plate. The mounting rod is disposed between the sliding plate and the support plate and can be clamped by the sliding plate and the support plate. In this solution, the cylinder can clamp the mounting rod connected to the housing by driving the sliding plate closer to the support plate, and can also drive the sliding plate away from the support plate to make the mounting rod disengage from the gap between the sliding plate and the support plate. In this way, the housing and the instant heating component inside the housing can be easily and detachably installed in the first receiving cavity and facilitate subsequent maintenance. This also helps to further improve the anti-fog effect of the automotive lamp in this application.

[0016] Optionally, the support assembly further includes a mounting seat connected to the mounting plate; the mounting seat forms a third receiving cavity, within which the cylinder, the sliding plate, and the support plate are disposed, and the mounting rod penetrates the sidewall of the mounting seat that forms the third receiving cavity so that the housing is located outside the third receiving cavity. In this solution, the mounting seat connected to the mounting plate can provide protection for the cylinder, the sliding plate, and the support plate through the third receiving cavity it forms. This allows the sliding plate and the support plate to provide a more stable clamping of the mounting rod, thereby enabling the housing connected to the mounting rod to maintain better installation position stability. This also helps to further improve the anti-fog effect of the automotive lamp in this application.

[0017] Optionally, a groove extending parallel to the cylinder output direction is formed on the mounting base; the end of the sliding plate is movably disposed within the groove and slidably connected to the mounting base through the groove. In this design, the groove formed on the mounting base provides sliding guidance for the sliding plate, thereby improving its sliding stability and further enhancing the anti-fog effect of the automotive lights in this application.

[0018] Optionally, the support assembly further includes a limiting rod connected to the sliding plate; the limiting rod is disposed on the side of the sliding plate opposite to the cylinder and perpendicular to the sliding plate, and the mounting rod has a hole with a shape adapted to the limiting rod for insertion. In this solution, by connecting a limiting rod that can be inserted into the corresponding hole on the mounting rod on the sliding plate, the stability of the housing's installation position can be improved, and the housing can also maintain good installation posture stability, which is also beneficial to further improving the anti-fog effect of the automotive lamp in this application.

[0019] Optionally, the support assembly further includes a support rod disposed in the third cavity; the support rod is vertically connected to the side of the support plate opposite to the cylinder and connected to the mounting base. In this solution, the support rod connected to the mounting base can provide support for the support plate, so that when the support plate cooperates with the sliding plate to clamp the mounting rod, it can form a better stable support effect, which is also conducive to further improving the anti-fog effect of the automotive lights in this application.

[0020] Optionally, at least two sets of the support components and the instant heating components are provided and evenly distributed around the center of the light source. In this solution, the at least two sets of support components and instant heating components effectively improve the efficiency and extent of water mist removal in the first receiving cavity, which also helps to further improve the anti-fog effect of the automotive lamp in this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The present application will now describe an automotive lamp provided in an embodiment. The automotive lamp includes a mounting plate 101, a transparent cover 102, a housing 104, a light source 108, and a heating element.

[0032] in:

[0033] The mounting plate 101 and the transparent cover 102 can adopt existing structures in the art. For example, the mounting plate 101 can be a commonly used plastic plate or metal plate, while the transparent cover 102 can be made of transparent acrylic material or glass. Furthermore, the transparent cover 102, by connecting to the mounting plate 101 and cooperating with the first receiving cavity 103 formed by the mounting plate 101, can be used to accommodate the light source 108 to achieve the illumination function of the automotive lamp. Similarly, the light source 108 used for illumination in this embodiment can also adopt a structure commonly used in automotive lamps in the art, such as an LED lamp, which will not be described in detail here.

[0034] The housing 104 is disposed within the first receiving cavity 103 and connected to the mounting plate 101. Additionally, the housing 104 forms a second receiving cavity 105, with an air inlet 106 and an air outlet 107 respectively connected to the second receiving cavity 105. In this embodiment, the housing 104 can independently form the second receiving cavity 105, or it can be combined with the mounting plate 101 and the transparent cover 102 to form the second receiving cavity 105. In specific implementations, it can be flexibly configured according to the shape of the first receiving cavity 103, achieving the same technical effect. Further details are omitted here. Furthermore, the air inlet 106 and the air outlet 107 should maintain a certain distance on the housing 104 to prevent heat discharged from the air outlet 107 from directly entering the second receiving cavity 105 through the air inlet 106.

[0035] The instant heating component is disposed within the second receiving cavity 105 and includes a blower capable of blowing air toward the air outlet 107 and a heating device 109 for generating heat. The heating device 109 is positioned between the blower and the air outlet 107 and is located in the airflow path of the blower. In this embodiment, the blower can be a device commonly used in the art to generate flowing air, such as a small fan, while the heating device 109 can be a structure commonly used in the art for generating heat, such as a resistance wire. Thus, when the heating device 109 generates heat, the flowing air generated by the blower can carry the heat generated by the heating device 109 to the target location.

[0036] According to the structure provided in this embodiment, in the automotive lamp of this embodiment, the first receiving cavity 103 formed by the transparent cover 102 and the mounting plate 101 is used not only to accommodate the light source 108, but also to accommodate the housing 104 and the instant heating component disposed in the second receiving cavity 105 on the housing 104. Since the housing 104 is provided with an air inlet 106 and an air outlet 107, and since the heating device 109 capable of generating heat is disposed between the air inlet 106 and the air outlet 107, when the blower blows air toward the air outlet 107, the heat generated by the heating device 109 can be effectively transferred to the first receiving cavity 103. This can eliminate the water mist that has already condensed on the transparent cover 102 and effectively prevent new water mist from condensing on the transparent cover 102. Therefore, the automotive lamp provided in this embodiment can eliminate the problem of water mist condensation inside the lamp, which is far superior to the prior art.

[0037] It should be noted that, since the purpose of the air inlet 106 and air outlet 107 in this embodiment is to facilitate heat exchange between the first receiving cavity 103 and the second receiving cavity 105, the position and shape of the air inlet 106 and air outlet 107 are not limited. In specific implementation, the position of the air inlet 106 and air outlet 107 can be flexibly set according to the shape of the first receiving cavity 103 and the second receiving cavity 105, and multiple of each can be set. In addition, the air inlet 106 can also be equipped with a dustproof net 110 or other structures to prevent impurities from entering the second receiving cavity 105. In this preferred embodiment, the air inlet 106 and the air outlet 107 are set to be perpendicular to each other, with the air outlet 107 facing the transparent cover 102. This allows the heated air discharged from the air outlet 107 to reach the transparent cover 102 more quickly, and also allows the air to circulate more smoothly, thereby further improving the anti-fog effect of the car lights in this embodiment.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3The blowing device includes a motor 111 and a rotor 113. The motor 111 forms an output shaft 112 with its axis parallel to the direction of the air outlet 107. The rotor 113 is coaxially connected to the output shaft 112 and can be driven to rotate by the output shaft 112. The air inlet 106 and the air outlet 107 are located on both sides of the rotor 113 along the axial direction of the output shaft 112. The motor 111 described in this embodiment can be a small electric motor commonly used in the art. When the motor 111 is energized, it can drive the rotor 113 to rotate and generate airflow along the axial direction of the output shaft 112. In addition, in this embodiment, the power supply method of the motor 111 can be either to connect the motor 111 to a separate battery or to connect the motor 111 to the vehicle's own power supply circuit. These methods are conventional techniques in the art and will not be described in detail here.

[0039] According to the structure provided in this embodiment, by setting the output shaft 112 parallel to the direction of the air outlet and the rotating blade 113 coaxially connected to the output shaft 112, the air blowing direction of the air blowing device can be parallel to the direction of the air outlet 107. In this way, the air blowing device can deliver the heat generated by the heating device 109 to the first receiving cavity 103 to the maximum extent, thereby further improving the anti-fog effect of the car lights in this embodiment.

[0040] It should be noted that in this embodiment, the motor 111 can also be located outside the second receiving cavity 105 and connected to the rotating blade 113 via an output shaft 112 extending into the second receiving cavity 105. This also achieves the technical effect of driving the rotating blade 113 to rotate and supplying air to the air outlet 107. Of course, in this embodiment, the motor 111 and the rotating blade 113 can also be replaced with other air supply structures commonly used in the art, such as small axial flow fans, etc. These implementations have the same technical effect. Further details will not be elaborated here. In addition, as a preferred embodiment, in this embodiment, the air inlet 106 and the air outlet 107 are arranged to be distributed along the axial direction of the output shaft 112 on opposite sides of the rotating blade 113. This allows the rotating blade 113 to provide flowing air more efficiently, which is beneficial for further improving the anti-fog effect of the automotive lights in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 At least two heating devices 109 are evenly distributed around the output shaft 112. According to the structure provided in this embodiment, the arrangement of at least two heating devices 109 around the output shaft 112 can effectively improve the hot air supply and supply efficiency of the instantaneous heating component. This not only removes water mist from the first receiving cavity 103 more thoroughly, but also removes water mist from the first receiving cavity 103 more quickly, which is beneficial to further improve the anti-fog effect of the automotive lights in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The heating assembly also includes a limiting block 114 disposed in the second receiving cavity 105 and connected to the housing 104; the limiting block 114 abuts against the opposite sides of the motor 111 so that the center of gravity of the housing 104 is located on the central axis of the output shaft 112.

[0043] According to the structure provided in this embodiment, by setting a limiting block 114 for limiting the motor 111 in the second receiving cavity 105, the axial direction of the output shaft 112 can pass through the center of gravity of the housing 104. In this way, the center of the rotating blade 113 coaxially connected to the output shaft 112 can also be located on the central axis of the housing 104. Thus, the heating component can make fuller use of the wind force generated by the blowing device, which can further improve the anti-fog effect of the car lights in this embodiment.

[0044] It is understood that multiple sets of limiting blocks 114 abutting against the opposite sides of the motor 111 can be respectively provided, which is beneficial to further improve the accuracy of the installation position of the motor 111. In addition, in some other embodiments of this application, the limiting blocks 114 can also be connected to the housing 104 through other connecting structures such as limiting rods 115, which can also significantly improve the accuracy of the installation position of the motor 111, thereby also helping to further improve the anti-fog effect of the automotive lights in this embodiment.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The automotive light also includes a support assembly; the support assembly includes a cylinder 116 and a support plate 117 spaced apart in the first receiving cavity 103, and also includes a sliding plate 118 connected to the power end of the cylinder 116 and a mounting rod 119 connected to the housing 104. The output direction of the cylinder 116 is towards the support plate 117 and can drive the sliding plate 118 to move closer to or away from the support plate 117. The mounting rod 119 is disposed between the sliding plate 118 and the support plate 117 and can be clamped by the sliding plate 118 and the support plate 117.

[0046] According to the structure provided in this embodiment, the cylinder 116 can clamp the mounting rod 119 connected to the housing 104 by driving the sliding plate 118 closer to the support plate 117, and can also drive the sliding plate 118 away from the support plate 117 to make the mounting rod 119 exit the gap between the sliding plate 118 and the support plate 117. In this way, the housing 104 and the instant heating component inside the housing 104 can be conveniently and detachably installed in the first receiving cavity 103 and facilitate subsequent maintenance. That is, when the blowing device or heating device 109 malfunctions, it can be repaired and replaced in time, which is also conducive to further improving the anti-fog effect of the car lights in this application.

[0047] It is understood that the shapes of the sliding plate 118 and the support plate 117 are not limited in this embodiment. They can be set to corresponding shapes in specific implementation to form a better clamping effect. Since the mounting rod 119 needs to be stably clamped between the sliding plate 118 and the support plate 117 to enable the housing 104 connected to the mounting rod 119 to have better installation position stability, the sides of the mounting rod 119 that abut against the sliding plate 118 and the support plate 117 can all be set as planes. This is beneficial for the mounting rod 119 to be stably clamped between the sliding plate 118 and the support plate 117, and also beneficial for further improving the anti-fog effect of the automotive lamp in this application. Of course, in some other embodiments of this application, the housing 104 can also be detachably installed in the first receiving cavity 103 by forming a detachable snap-fit ​​with the mounting plate 101. Since these detachable connection methods achieve the same technical effect as the structure provided in this embodiment, they should be regarded as variations of the structure in this embodiment and are within the protection scope of this utility model. They will not be described in detail here.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The support assembly also includes a mounting base 120 connected to the mounting plate 101; the mounting base 120 forms a third receiving cavity 121, and the cylinder 116, the sliding plate 118 and the support plate 117 are disposed in the third receiving cavity 121. The mounting rod 119 passes through the mounting base 120 to form the side wall of the third receiving cavity 121 so that the housing 104 is located outside the third receiving cavity 121.

[0049] According to the structure provided in this embodiment, the mounting base 120 connected to the mounting plate 101 can provide protection for the cylinder 116, the sliding plate 118, and the support plate 117 through its own third accommodating cavity 121. In this way, the sliding plate 118 and the support plate 117 can clamp the mounting rod 119 more stably, and the housing 104 connected to the mounting rod 119 can also maintain better installation position stability, which is also conducive to further improving the anti-fog effect of the car light in this embodiment.

[0050] It is understood that the purpose of the mounting base 120 in this embodiment is, on the one hand, to provide protection for the cylinder 116, the sliding plate 118, and the support plate 117, and on the other hand, to better install and fix the housing 104. Therefore, the shape of the mounting base 120 itself and the third receiving cavity 121 in this embodiment are not limited, but the holes for the mounting rod 119 to pass through must correspond to the mounting rod 119. This ensures that the mounting rod 119 can pass through smoothly and that the housing 104 can achieve better stability in its installation position. For example, in the aforementioned embodiment where the mounting rod 119 has flat surfaces on both sides, the holes on the mounting base 120 for the mounting rod 119 to pass through can also be set to a corresponding shape. Furthermore, the connection method between the mounting base 120 and the mounting plate 101 is not limited. In specific implementation, the mounting base 120 can be fixedly connected to the mounting plate 101 by welding or integral molding. Other commonly used detachable connection methods in the art, such as snap-fit, can also be used to form a detachable connection with the mounting plate 101, which will not be elaborated here.

[0051] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 A groove 122 is formed on the mounting base 120, with its extension direction parallel to the output direction of the cylinder 116; the end of the sliding plate 118 is movably disposed in the groove 122 and forms a sliding connection with the mounting base 120 through the groove 122.

[0052] According to the structure provided in this embodiment, the groove 122 formed on the mounting base 120 can provide sliding guidance for the sliding plate 118, which can improve the sliding stability of the sliding plate 118 and further improve the anti-fog effect of the car light in this embodiment.

[0053] In a preferred embodiment, two parallel grooves 122 are provided at intervals at both ends of the sliding plate 118, allowing both ends of the sliding plate 118 to move within the grooves 122, thus improving the sliding stability of the sliding plate 118. Furthermore, in this embodiment, the ends of the sliding plate 118 are directly disposed within the grooves 122 and slide within them. However, in other embodiments of this application, the ends of the sliding plate 118 can also be connected to sliders 123 whose shapes are adapted to the grooves 122. This allows the grooves 122 and sliders 123 to be more flexibly reshaped while maintaining a stable sliding connection, achieving the same technical effect as the structure provided in this embodiment, which will not be elaborated further here.

[0054] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The support assembly also includes a limiting rod 124 connected to the sliding plate 118; the limiting rod 124 is disposed on the side of the sliding plate 118 away from the cylinder 116 and perpendicular to the sliding plate 118, and the mounting rod 119 has a hole (not shown in the figure) formed on it, which is adapted to the shape of the limiting rod 124 and allows the limiting rod 124 to be inserted.

[0055] According to the structure provided in this embodiment, by connecting the limiting rod 124 that can be inserted into the corresponding hole on the mounting rod 119 to the sliding plate 118, the installation position stability of the housing 104 can be improved, and the housing 104 can also maintain good installation posture stability, which is also conducive to further improving the anti-fog effect of the car light in this embodiment.

[0056] It is understood that the purpose of the limiting rod 124 in this embodiment is to prevent the mounting rod 119 from rotating. This means that the cross-sectional shape of the limiting rod 124 is not limited and can be set to a circular, rectangular, or polygonal structure commonly used in the art. Correspondingly, the shape of the hole on the mounting rod 119 for the limiting rod 124 to be inserted needs to be matched according to the shape of the limiting rod 124. In addition, in this embodiment, multiple limiting rods 124 connected to the sliding plate 118 can be set at intervals to improve the connection stability between them and the mounting rod 119. For ease of explanation, this embodiment uses two limiting rods set at intervals as an example.

[0057] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 The support assembly also includes a support rod 125 disposed in the third cavity; the support rod 125 is vertically connected to the side of the support plate 117 away from the cylinder 116 and is connected to the mounting base 120.

[0058] According to the structure provided in this embodiment, the support rod 125 connected to the mounting base 120 can support the support plate 117. In this way, when the support plate 117 cooperates with the sliding plate 118 to clamp the mounting rod 119, it can form a better stable support effect, which is also conducive to further improving the anti-fog effect of the car lights in this application.

[0059] It is understood that in this embodiment, the support rod 125 is connected to the support plate 117 in a posture perpendicular to the support plate 117, which can provide better support for the support plate 117. However, in some other embodiments of this application, the support rod 125 can also be arranged at an angle to the support plate 117 to provide support for the support plate 117, which can also provide a stable support effect for the support plate 117 to a certain extent. In addition, one or more support rods 125 can be provided in this embodiment. For ease of explanation, this embodiment uses one support rod 125 as an example for description.

[0060] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 , Figure 2 and Figure 3 At least two sets of support components and instant heating components are provided and evenly distributed around the center of the light source 108. In this embodiment, the at least two sets of support components and instant heating components distributed around the center of the light source 108 can achieve the technical effect of not affecting the illumination of the light source 108.

[0061] According to the structure provided in this embodiment, the efficiency and extent of water mist removal in the first receiving cavity 103 can be effectively improved by the at least two sets of supporting components and instant heating components provided in this embodiment, which is also conducive to further improving the anti-fog effect of the car lights in this embodiment.

[0062] It is understood that the supporting components and instant heating components provided in this embodiment are essentially for providing heat to the target location in the first receiving cavity 103, thereby effectively eliminating the water mist condensed in the first receiving cavity 103. From this perspective, multiple sets of supporting components and instant heating components can be provided. However, the purpose of this embodiment is mainly to provide an automotive lamp, so its primary function is still for automotive lighting. Therefore, if too many supporting components and instant heating components are provided in the first receiving cavity 103, it will affect the lighting effect of the automotive lamp. Therefore, in actual production applications, the supporting components and instant heating components should ultimately be appropriately set according to the size and shape of the first receiving cavity 103 to ensure that the automotive lamp in this embodiment can maintain a good anti-fog effect while ensuring the lighting effect.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
