Description

Technical Field

[0001] The present application relates to the field of heat dissipation technology, and in particular to a connection structure, a heat dissipation device and a mobile terminal. Background Art

[0002] As the automotive industry grows and develops, headlights, as functional and styling parts of vehicles, play an increasingly important role in the competitiveness of the entire vehicle. In the future, headlights will develop towards a trend of more beautiful shapes, higher performance, and richer functions. With the improvement of headlight performance and power, the heat dissipation problem of headlights has become a major obstacle to product evolution.

[0003] The current full-load power of headlights is as high as 50W, and can even reach more than 60W. However, due to the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light emitter. Therefore, in most usage scenarios, the light output of the headlight has to be reduced, sacrificing the performance of the headlight to ensure the reliability of the headlight.

[0004] Therefore, a feasible solution is urgently needed to improve the heat dissipation efficiency of the headlights while taking into account the requirements of headlight performance and reliability. Utility Model Content

[0005] The embodiments of the present application provide a connection structure, a heat dissipation device and a movable terminal, which can improve the heat dissipation efficiency of the vehicle lamp and take into account the requirements of the performance and reliability of the vehicle lamp.

[0006] In a first aspect, an embodiment of the present application provides a connection structure, the connection member comprising:

[0007] A connecting member, a first component, and a second component;

[0008] The material of the connecting member includes an elastic material; the first member is fixedly connected to the lamp housing, the second member is fixedly connected to the lamp housing, the lamp housing is provided with an opening, the connecting member, the first member and the second member all surround the opening, and in the axial direction of the opening, a first clamping space is provided between the first member and the second member;

[0009] One end of the connecting member is fixed in the first clamping space, the first component, one end of the connecting member and the second component are stacked in sequence along the radial direction of the opening, and the connecting member includes a first surface and a second surface opposite to each other along its thickness direction, the first surface abuts the first component, and the second surface abuts the second component.

[0010] In an embodiment of the present application, a connection structure is provided, which relates to the field of heat dissipation technology and can be specifically applied to vehicle lights for connecting lamp housings and / or lamp groups and / or heat dissipation components to improve the heat dissipation efficiency of the vehicle lights while taking into account the requirements of vehicle light performance and reliability.

[0011] Wherein, the connection structure includes a connector, a first component and a second component, and the material of the connector includes an elastic material, so the connector can be understood as a flexible connection structure. The first component is fixedly connected to the lamp housing, and the second component is fixedly connected to the lamp housing. It can be understood that the first component can specifically be a side wall of the lamp housing, which is integrally formed with the lamp housing, and the second component can specifically be a side pressure plate of the lamp housing, which is fixedly connected to the lamp housing by fasteners such as screws and pins. In addition, the lamp housing is provided with an opening, and the connector, the first component and the second component all surround the opening, and surround the axial direction of the opening. It can be understood that the connector, the first component and the second component are all annular structures that surround the axial direction of the opening, and the annular structure can be a square ring structure, a circular ring structure, an elliptical ring structure, etc., and the embodiments of the present application do not limit this. A first clamping space is provided between the first component and the second component, one end of the connector is fixed in the first clamping space, the first component, one end of the connector and the second component are stacked in sequence along the radial direction of the opening, and the first surface of the connector abuts the first component, and the second surface of the connector abuts the second component. It can be understood that one end of the connector adopts a radial sealing connection, so that the first component, one end of the connector and the second component form a three-layer sealing connection structure with one end of the connector located in the middle, which increases the sealing area and improves the sealing reliability, and the heat dissipation component can be arranged in the annular structure formed by the connector, so that the heat dissipation component is arranged on the outside of the lamp housing, which can realize the externalization of the heat dissipation component and improve the heat dissipation efficiency of the vehicle lamp.

[0012] The sealing width of the current connection structure used to connect the lamp housing and / or lamp assembly and / or heat dissipation components is too narrow. When the connector in the connection structure is twisted and deformed, it will increase the difficulty of installation and the risk of air leakage, and the sealing reliability is low. In addition, the current connection structure adopts a sealing method along the optical axis direction, which requires a full circle of pressure plates for sealing, which occupies a large area of ​​the lamp housing, and the fixing parts must be evenly distributed around the pressure plates to ensure the compression of the sealing position of the connection structure. In some lamp housings with tight space, there is a problem that the connection structure cannot be arranged.

[0013] In the embodiment of the present application, the connector in the connection structure adopts radial sealing connection, which increases the sealing area. Even if the end of the connector is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the lamp and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the sum of the thickness of the first component (the side wall of the lamp housing), one end of the connector, and the second component (the side pressure plate of the lamp housing), and the area occupied by the lamp housing is small. The fixing parts do not need to be arranged evenly, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the lamp, taking into account the performance and reliability requirements of the lamp.

[0014] In a possible implementation manner, the connection structure further includes:

[0015] The third component, the fourth component;

[0017] The other end of the connecting member is fixed in the second clamping space, and the third component, the other end of the connecting member and the fourth component are stacked in sequence along the radial direction of the lamp group. The connecting member includes a third surface and a fourth surface opposite to each other along its thickness direction, and the third surface abuts the third component, and the fourth surface abuts the fourth component.

[0018] In the embodiment of the present application, the connection structure further includes a third component and a fourth component. The third component is fixedly connected to the lamp group, and the fourth component is fixedly connected to the lamp group. It can be understood that the third component can be specifically a side wall of the lamp group, which is integrally formed with the lamp group, and the fourth component can be specifically a side pressure plate of the lamp group, which is fixedly connected to the lamp group by fasteners such as screws and pins. In addition, the connection member, the third component, and the fourth component all surround the axial direction of the lamp group. It can be understood that the connection member, the third component, and the fourth component are all annular structures that surround the axial direction of the lamp group, and the annular structure can be a square ring structure, a circular ring structure, an elliptical ring structure, etc., which is not limited in the embodiment of the present application. There is a second clamping space between the third component and the fourth component, and the other end of the connector is fixed in the second clamping space. The third component, the other end of the connector and the fourth component are stacked in sequence along the radial direction of the lamp group, and the third surface of the connector abuts the third component, and the fourth surface of the connector abuts the fourth component. It can be understood that the other end of the connector adopts a radial sealing connection, so that the third component, the other end of the connector and the fourth component form a three-layer sealing connection structure with the other end of the connector located in the middle, which increases the sealing area and improves the sealing reliability, and the heat dissipation component can be arranged in the annular structure formed by the connector, so that the heat dissipation component is arranged on the outside of the lamp housing, which can realize the externalization of the heat dissipation component and improve the heat dissipation efficiency of the car lamp.

[0019] In the implementation manner of the present application, the connector in the connection structure adopts a radial sealing connection, which increases the sealing area. Even if the end of the connector is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the headlight and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the thickness of the third component (the side wall of the lamp group), the other end of the connector, and the fourth component (the side pressure plate of the lamp group) added together, and the area occupied by the lamp group is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the headlight, taking into account the performance and reliability requirements of the headlight.

[0020] In a possible implementation manner, the third component and the fourth component are arranged on an inner side of the opening, the axial direction of the third component is parallel to the axial direction of the opening, and the axial direction of the fourth component is parallel to the axial direction of the opening.

[0021] In the embodiment of the present application, a possible specific implementation of the position of the third component and the fourth component is provided, specifically, the third component and the fourth component are arranged on the inner side of the lamp housing opening, the axial direction of the third component is parallel to the axial direction of the lamp housing opening, and the axial direction of the fourth component is parallel to the axial direction of the lamp housing opening. It can be understood that at this time, the lamp housing opening and the heat dissipation component of the lamp group are in the same direction, and the tail of the lamp housing is higher than the heat dissipation component of the lamp group, that is, the lamp housing opening, the connecting structure and the heat dissipation component of the lamp group form a notch shape, and the flexible sealing connection of the connecting structure can ensure the sealing of the lamp while achieving heat dissipation of the lamp, and realize the position adjustment of the lamp group, thereby realizing the dimming function of the lamp, taking into account the requirements of the performance and reliability of the lamp. In addition, the heat dissipation component of the lamp group is placed outside the lamp housing, which can make full use of the limited space inside the lamp and improve the utilization rate of space resources.

[0022] In a possible implementation, the axial center axis of the opening coincides with the axial center axis of the heat dissipation component of the lamp group, or the axial center axis of the opening and the axial center axis of the heat dissipation component of the lamp group have a first offset along the radial direction of the opening.

Alternatively, there is a first offset between the axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp group along the radial direction of the lamp housing opening, which can be understood as the lamp housing opening and the heat dissipation component of the lamp group are misaligned in the radial direction of the lamp housing opening. Through the embodiments of the present application, the lamp housing opening and the heat dissipation component of the lamp group can be aligned or misaligned, which improves the flexibility of adaptation.

It can be understood that at this time, the lamp housing opening and the heat dissipation component of the lamp group are in the same direction, and the lamp housing opening, the connecting structure and the heat dissipation component of the lamp group form a convex shape. Through the flexible sealing connection of the connecting structure, the heat dissipation of the lamp can be achieved while ensuring the sealing of the lamp, and the position of the lamp group can be adjusted, thereby realizing the dimming function of the lamp, taking into account the requirements of the performance and reliability of the lamp. In addition, the heat dissipation component of the lamp group is placed outside the lamp housing, which can make full use of the limited space inside the lamp and improve the utilization rate of space resources.

[0028] In a possible implementation, the axial center axis of the opening coincides with the axial center axis of the heat dissipation component of the lamp group, or the axial center axis of the opening and the axial center axis of the heat dissipation component of the lamp group have a second offset along the radial direction of the opening.

[0029] In the embodiments of the present application, a possible specific implementation of the relative positional relationship between the lamp housing opening and the heat dissipation component of the lamp group is provided, specifically, the axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp group coincide with each other, which can be understood as the lamp housing opening and the heat dissipation component of the lamp group are aligned in the radial direction of the lamp housing opening, or can be understood as the lamp housing opening and the heat dissipation component of the lamp group are aligned in the axial direction of the lamp housing opening. Alternatively, there is a second offset between the axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp group along the radial direction of the lamp housing opening, which can be understood as the lamp housing opening and the heat dissipation component of the lamp group are misaligned in the radial direction of the lamp housing opening. Optionally, there can also be misalignment between the lamp housing opening and the heat dissipation component of the lamp group in the axial direction of the lamp housing opening. Through the embodiments of the present application, the lamp housing opening and the heat dissipation component of the lamp group can be aligned or misaligned, thereby improving the flexibility of adaptation.

[0030] In a possible implementation, the third component and the fourth component are arranged on the inner side of the opening, the angle between the axial direction of the third component and the axial direction of the opening is a first angle, and the angle between the axial direction of the fourth component and the axial direction of the opening is the first angle.

It can be understood that at this time, the lamp housing opening and the heat dissipation component of the lamp group are not in the same direction and are not aligned, and the lamp housing opening, the connection structure and the heat dissipation component of the lamp group form a special-shaped channel notch shape. Through the flexible sealing connection of the connection structure, the heat dissipation of the lamp can be achieved while ensuring the sealing of the lamp, and the position adjustment of the lamp group can be achieved, thereby achieving the dimming function of the lamp, taking into account the requirements of the performance and reliability of the lamp. In addition, the heat dissipation component of the lamp group is placed outside the lamp housing, which can make full use of the limited space inside the lamp and improve the utilization rate of space resources.

[0032] In a possible implementation, the connecting member includes:

[0033] Connecting part and deformation part;

Among them, the deforming portion includes at least one first fold segment, the extension direction of the first fold segment is parallel to the circumference of the connector, and it can be understood that the first fold segment adopts a transverse spiral pattern of folds, and through the elastic deformation of the deforming portion, the position of the lamp group can be adjusted while ensuring the sealing of the car lamp, thereby realizing the dimming function of the car lamp, taking into account the requirements of the performance and reliability of the car lamp, and the relative position relationship between the lamp housing opening and the heat dissipation component of the lamp group can be flexibly arranged, thereby improving the adaptation flexibility and space resource utilization. In some embodiments, the extension direction of the first fold segment is parallel to the axial direction of the connector, and it can be understood that the first fold segment adopts a vertical stripe fold, which is conducive to the removal of liquid cooling condensed water of the heat dissipation component, and can improve the heat dissipation efficiency of the car lamp.

[0058] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0059] The terms "first" and "second" in the specification, claims and drawings of this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0060] The "embodiment" mentioned in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be explicitly and implicitly understood by those skilled in the art that in the various embodiments of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0061] It should be understood that in the present application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0062] In the description of the present application, the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", "left", "side", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present application. It should be understood that the Z direction, Y direction, etc. mentioned in some embodiments of the present application are based on the XYZ rectangular coordinate system as a reference to facilitate the description of the features in the present solution, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation.

[0063] In the embodiments of the present application, the "end" appearing in the terms "one end", "the other end", "end", "free end", "upper end", "lower end", "connecting end", etc. is not limited to the end head, endpoint or end face, but also includes a portion extending an axial distance and / or radial distance from the end head, endpoint, or end face on the device or element to which the end head, endpoint, or end face belongs.

[0064] As described in the background technology section, the current full-load power of car lamp light sources is as high as 50W, and can even reach more than 60W. However, due to the limitations of the closed space inside the lamp, the air temperature inside the lamp cannot form exchange convection with the outside world, and the heat dissipation efficiency is low, which can easily cause the ambient temperature inside the lamp to rise sharply and burn out the light-emitting body. As a result, in most usage scenarios, it is necessary to reduce the luminous power of the car lamp and sacrifice the performance of the car lamp to ensure the reliability of the car lamp.

[0065] For details, please refer to Figure 1 , Figure 1 A cross-sectional schematic diagram of a heat dissipation device provided in an embodiment of the present application.

[0066] like Figure 1 As shown, the heat dissipation device includes a lampshade, a lamp assembly, a lamp housing and a heat dissipation component. The heat dissipation component is arranged inside the lamp housing, and the heat dissipation efficiency is low. It is necessary to reduce the luminous power of the lamp and sacrifice the performance of the lamp to ensure the reliability of the lamp.

[0067] Currently, with the increase of the luminous power of the lamp group, higher requirements are placed on the heat dissipation capacity. Accordingly, a solution for heat dissipation outside the lamp has been proposed, that is, the heat dissipation components of the lamp group are isolated outside the lamp for heat dissipation. Accordingly, in order to maintain the sealing of the entire lamp and ensure that the lamp group can move up, down, left and right during the dimming process, a soft connection structure is adopted, with one end connected to the lamp group and the other end connected to the lamp housing. This can maintain sealing without restricting the movement of the lamp group.

[0068] For details, please refer to Figure 2 , Figure 2 A cross-sectional schematic diagram of a heat dissipation device provided in an embodiment of the present application.

[0069] like Figure 2 As shown, the heat dissipation device includes a lampshade 10 , a lamp housing 20 , a connector 30 , a heat dissipation component 40 , and a lamp assembly 50 .

[0070] The connector 30 is provided with a mounting hole, which penetrates the connector 30 along the thickness direction of the connector 30. It can be understood that the position of the mounting hole can be used to place the heat dissipation component 40. The heat dissipation component 40 is arranged outside the lamp housing 20 through the mounting hole, so that the heat dissipation component 40 can be placed outside to improve the heat dissipation efficiency of the lamp. And through the elastic deformation of the connector 30, the position of the lamp group 50 can be adjusted while ensuring the sealing of the lamp, thereby realizing the dimming function of the lamp, taking into account the requirements of the lamp performance and reliability.

[0071] However, the current connectors used to connect the lamp housing and / or the lamp assembly and / or the heat dissipation component still have the following problems:

[0072] (1) The sealing width in the connector is too narrow. When the connector is twisted and deformed, it will increase the difficulty of installation and the risk of air leakage, and the sealing reliability is low.

[0073] (2) The connector adopts a sealing method along the optical axis (such as Figure 2 As shown in the dotted area 60 in the figure, a whole circle of pressure plate sealing is required, which occupies a large area of ​​the lamp housing, and the fixing parts must be evenly distributed around the pressure plate to ensure the compression amount of the sealing position of the connection structure. In some lamp housings with tight space, there is a problem that the connecting parts cannot be arranged.

[0074] Therefore, a feasible solution is urgently needed to improve the heat dissipation efficiency of the headlights while taking into account the requirements of headlight performance and reliability.

[0075] In view of this, the present application provides a connection structure, a heat dissipation device and a movable terminal, which relate to the field of heat dissipation technology and can be specifically applied to vehicle lights to improve the heat dissipation efficiency of the vehicle lights while taking into account the performance and reliability requirements of the vehicle lights.

[0081] By the above Figure 3 and Figure 4It can be seen that the embodiment of the present application provides a connection structure, which relates to the field of heat dissipation technology and can be specifically applied to vehicle lights for connecting lamp housings and / or lamp groups and / or heat dissipation components to improve the heat dissipation efficiency of vehicle lights while taking into account the performance and reliability requirements of vehicle lights.

[0082] Specifically, the connection structure includes:

[0083] Connecting member 101 , first component 102 , second component 103 .

[0084] The material of the connecting member 101 includes elastic material, so the connecting member can be understood as a flexible connecting structure.

[0085] The first component 102 is fixedly connected to the lamp housing, and the second component 103 is fixedly connected to the lamp housing. It can be understood that the first component 102 can be a side wall of the lamp housing, which is integrally formed with the lamp housing, and the second component 103 can be a side pressure plate of the lamp housing, which is fixedly connected to the lamp housing by fasteners such as screws and pins. The specific method of fixing the second component 103 to the lamp housing is not limited in the embodiment of the present application.

[0086] Optionally, the second component 103 (lamp housing side pressure plate) can be fixedly connected to the lamp housing in an L-shape on the outside or inside of the lamp housing, or can be fixedly connected to the lamp housing in other shapes, which is not limited in the embodiment of the present application.

[0087] The lamp housing is provided with an opening, and the connecting member 101, the first component 102, and the second component 103 all surround the opening and surround the axial direction of the opening. It can be understood that the connecting member 101, the first component 102, and the second component 103 are all annular structures surrounding the axial direction of the opening, and the annular structure can be a square ring structure, a circular ring structure, an elliptical ring structure, etc., which is not limited in the embodiment of the present application.

[0088] There is a first clamping space between the first component 102 and the second component 103, one end of the connector 101 is fixed in the first clamping space, the first component 102, one end of the connector 101 and the second component 103 are stacked in sequence along the radial direction of the opening, and the connector 101 includes a first surface 101a and a second surface 101b opposite to each other along the thickness direction thereof, the first surface 101a abuts the first component 102, and the second surface 101b abuts the second component 103. It can be understood that one end of the connector 101 is connected by radial sealing, so that the first component 102, one end of the connector 101 and the second component 103 form a three-layer sealing connection structure with one end of the connector 101 in the middle, which increases the sealing area and improves the sealing reliability, and the heat dissipation component can be arranged in the annular structure formed by the connector 101, so that the heat dissipation component is arranged outside the lamp housing, which can realize the external placement of the heat dissipation component and improve the heat dissipation efficiency of the lamp.

[0089] The sealing width of the current connection structure used to connect the lamp housing and / or lamp assembly and / or heat dissipation components is too narrow. When the connector in the connection structure is twisted and deformed, it will increase the difficulty of installation and the risk of air leakage, and the sealing reliability is low. In addition, the current connection structure adopts a sealing method along the optical axis direction, which requires a full circle of pressure plates for sealing, which occupies a large area of ​​the lamp housing, and the fixing parts must be evenly distributed around the pressure plates to ensure the compression of the sealing position of the connection structure. In some lamp housings with tight space, there is a problem that the connection structure cannot be arranged.

[0090] In the embodiment of the present application, the connector 101 in the connection structure adopts a radial sealing connection, which increases the sealing area. Even if the end of the connector 101 is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the lamp and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the sum of the thickness of the first component 102 (the side wall of the lamp housing), one end of the connector 101, and the second component 103 (the side pressure plate of the lamp housing), and the area occupied by the lamp housing is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the lamp, taking into account the performance and reliability requirements of the lamp.

It can be understood that the other end of the connector 101 is radially sealed and connected, so that the third component 104, the other end of the connector 101 and the fourth component 105 form a three-layer sealed connection structure with the other end of the connector 101 located in the middle, which increases the sealing area and improves the sealing reliability, and the heat dissipation component can be arranged in the annular structure formed by the connector 101, so that the heat dissipation component is arranged outside the lamp housing, and the heat dissipation component can be externalized to improve the heat dissipation efficiency of the lamp.

[0098] In the embodiment of the present application, the connector 101 in the connection structure adopts radial sealing connection, which increases the sealing area. Even if the end of the connector 101 is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the headlight and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the thickness of the third component 104 (side wall of the lamp group), the other end of the connector 101, and the fourth component 105 (side pressure plate of the lamp group) added together, and the area occupied by the lamp group is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the headlight, taking into account the requirements of the performance and reliability of the headlight.

[0099] In a possible embodiment, the third component 104 and the fourth component 105 are arranged inside the lamp housing opening, the axial direction of the third component 104 is parallel to the axial direction of the lamp housing opening, and the axial direction of the fourth component 105 is parallel to the axial direction of the lamp housing opening.

[0100] It can be understood that the lamp housing opening and the heat dissipation component of the lamp assembly are in the same direction, and the tail of the lamp housing is higher than the heat dissipation component of the lamp assembly, that is, the lamp housing opening, the connection structure and the heat dissipation component of the lamp assembly form a notch shape. Through the flexible sealing connection of the connection structure, the heat dissipation of the lamp can be achieved while ensuring the sealing of the lamp, and the position of the lamp assembly can be adjusted, thereby achieving the dimming function of the lamp, taking into account the requirements of lamp performance and reliability. In addition, the heat dissipation component of the lamp assembly is placed outside the lamp housing, which can make full use of the limited space inside the lamp and improve the utilization rate of space resources.

[0101] In a possible embodiment, the axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp assembly coincide with each other, or the axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp assembly have a first offset along the radial direction of the lamp housing opening.

[0102] The axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp assembly coincide with each other, which can be understood as the lamp housing opening and the heat dissipation component of the lamp assembly being aligned in the radial direction of the lamp housing opening. Alternatively, the axial center axis of the lamp housing opening and the axial center axis of the heat dissipation component of the lamp assembly have a first offset along the radial direction of the lamp housing opening, which can be understood as the lamp housing opening and the heat dissipation component of the lamp assembly being misaligned in the radial direction of the lamp housing opening.

[0103] It should be noted that Figure 3 and Figure 4 The lamp housing opening shown is aligned with the heat dissipation component of the lamp assembly in the radial direction of the lamp housing opening. Figure 3 and Figure 4This is only described as an example and should not be used to limit the embodiments of the present application.

[0108] The deformable portion is fixedly connected to the connecting portion. It can be understood that both the deformable portion and the connecting portion are annular structures surrounding the lamp housing opening and / or the axial direction of the lamp assembly.

[0109] The deformation portion includes at least one first pleated section, and the extension direction of the first pleated section is parallel to the circumference of the connector 101. It can be understood that the first pleated section adopts pleats with transverse spiral patterns.

Alternatively, the extension direction of the first pleated section can also be parallel to the axial direction of the connector 101. It can be understood that the first pleated section adopts pleats with vertical stripes, which is conducive to the removal of liquid cooling condensed water of the heat dissipation components and can improve the heat dissipation efficiency of the lamp. In a possible embodiment, the deformation portion also includes at least one second pleated section, and the extension direction of the second pleated section is parallel to the circumference of the connector 101, or the extension direction of the second pleated section is parallel to the axial direction of the connector 101.

It can be understood that the first pleat segment adopts transverse spiral pleats. Through the elastic deformation of the deformation part, the position of the lamp group can be adjusted while ensuring the sealing of the lamp, thereby realizing the dimming function of the lamp, and taking into account the requirements of lamp performance and reliability. The deformation part also includes at least one second pleat segment, and the extension direction of the second pleat segment is parallel to the axial direction of the connecting piece 101. It can be understood that the second pleat segment adopts vertical stripes of pleats, which is beneficial to the removal of liquid cooling condensed water of the heat dissipation components and can improve the heat dissipation efficiency of the lamp.

[0116] The heat dissipation component is located outside the lamp housing, and the connection structure is fixedly connected to the lamp housing and the lamp assembly.

[0117] In the heat dissipation device in the embodiment of the present application, the connector in the connection structure adopts radial sealing connection, which increases the sealing area. Even if the end of the connector is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the lamp and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the sum of the thickness of the first component (the side wall of the lamp housing), one end of the connector, and the second component (the side pressure plate of the lamp housing), and the area occupied by the lamp housing is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the lamp, taking into account the performance and reliability requirements of the lamp.

[0118] By the above Figure 5 and Figure 6 It can be seen that the embodiment of the present application provides another connection structure, which relates to the field of heat dissipation technology and can be specifically applied to vehicle lights for connecting lamp housings and / or lamp groups and / or heat dissipation components to improve the heat dissipation efficiency of vehicle lights while taking into account the performance and reliability requirements of vehicle lights.

[0119] Specifically, the connection structure includes:

[0120] Connecting member 201 , first component 202 , second component 203 .

It can be understood that the first pleated section adopts pleats with vertical stripes, which is conducive to the removal of liquid cooling condensed water from the heat dissipation components and can improve the heat dissipation efficiency of the lamp.

[0145] In a possible embodiment, the deformation portion further includes at least one second fold segment, and the extension direction of the second fold segment is parallel to the circumference of the connecting member 201 , or the extension direction of the second fold segment is parallel to the axial direction of the connecting member 201 .

[0146] It can be understood that the deformation part includes at least one first pleat segment, and the extension direction of the first pleat segment is parallel to the circumference of the connecting piece 201. It can be understood that the first pleat segment adopts transverse spiral pleats. Through the elastic deformation of the deformation part, the position of the lamp group can be adjusted while ensuring the sealing of the lamp, thereby realizing the dimming function of the lamp, and taking into account the requirements of lamp performance and reliability. The deformation part also includes at least one second pleat segment, and the extension direction of the second pleat segment is parallel to the axial direction of the connecting piece 201. It can be understood that the second pleat segment adopts vertical stripes of pleats, which is beneficial to the removal of liquid cooling condensed water of the heat dissipation components and can improve the heat dissipation efficiency of the lamp.

[0147] Accordingly, the above Figure 5 and Figure 6 It can be seen that the embodiment of the present application also provides another heat dissipation device, which relates to the field of heat dissipation technology and can be specifically applied to vehicle lights to improve the heat dissipation efficiency of the vehicle lights while taking into account the performance and reliability requirements of the vehicle lights.

[0148] Specifically, the heat dissipation device includes: a lamp group, and Figure 5 and Figure 6 The connection structure shown in .

[0149] Alternatively, the heat dissipation device comprises a lamp housing, and Figure 5 and Figure 6 The connection structure shown in .

[0150] Alternatively, the heat dissipation device includes a lamp housing, a lamp assembly, and Figure 5 and Figure 6 The connection structure shown in .

[0151] Alternatively, the heat dissipation device includes a lamp housing, a lamp assembly, a heat dissipation component, and Figure 5 and Figure 6 The connection structure shown in .

[0152] The heat dissipation component is located outside the lamp housing, and the connection structure is fixedly connected to the lamp housing and the lamp assembly.

[0153] In the heat dissipation device in the embodiment of the present application, the connector in the connection structure adopts radial sealing connection, which increases the sealing area. Even if the end of the connector is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the lamp and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the sum of the thickness of the first component (the side wall of the lamp housing), one end of the connector, and the second component (the side pressure plate of the lamp housing), and the area occupied by the lamp housing is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the lamp, taking into account the performance and reliability requirements of the lamp.

[0154] By the above Figure 7 and Figure 8 It can be seen that the embodiment of the present application provides another connection structure, which relates to the field of heat dissipation technology and can be specifically applied to vehicle lights for connecting lamp housings and / or lamp groups and / or heat dissipation components to improve the heat dissipation efficiency of vehicle lights while taking into account the performance and reliability requirements of vehicle lights.

[0155] Specifically, the connection structure includes:

[0156] Connecting piece 301 , first component 302 , and second component 303 .

[0157] The material of the connecting member 301 includes elastic material, so the connecting member can be understood as a flexible connecting structure.

[0158] The first component 302 is fixedly connected to the lamp housing, and the second component 303 is fixedly connected to the lamp housing. It is understandable that the first component 302 may be a side wall of the lamp housing, which is integrally formed with the lamp housing, and the second component 303 may be a side pressure plate of the lamp housing, which is fixedly connected to the lamp housing by fasteners such as screws and pins. The specific method of fixing the second component 303 to the lamp housing is not limited in the embodiment of the present application.

[0159] Optionally, the second component 303 (lamp housing side pressure plate) can be fixedly connected to the lamp housing in an L-shape on the outside or inside of the lamp housing, or can be fixedly connected to the lamp housing in other shapes, which is not limited in this embodiment of the present application.

[0160] The lamp housing is provided with an opening, and the connecting member 301, the first component 302 and the second component 303 all surround the opening and surround the axial direction of the opening. It can be understood that the connecting member 301, the first component 302 and the second component 303 are all annular structures surrounding the axial direction of the opening, and the annular structure can be a square ring structure, a circular ring structure, an elliptical ring structure, etc., which is not limited in the embodiment of the present application.

[0161] There is a first clamping space between the first component 302 and the second component 303, one end of the connector 301 is fixed in the first clamping space, the first component 302, one end of the connector 301 and the second component 303 are stacked in sequence along the radial direction of the opening, and the connector 301 includes a first surface 301a and a second surface 301b opposite to each other along the thickness direction thereof, the first surface 301a abuts the first component 302, and the second surface 301b abuts the second component 303. It can be understood that one end of the connector 301 is connected by radial sealing, so that the first component 302, one end of the connector 301 and the second component 303 form a three-layer sealing connection structure with one end of the connector 301 in the middle, which increases the sealing area and improves the sealing reliability, and the heat dissipation component can be arranged in the annular structure formed by the connector 301, so that the heat dissipation component is arranged outside the lamp housing, which can realize the external placement of the heat dissipation component and improve the heat dissipation efficiency of the vehicle lamp.

[0162] The sealing width of the current connection structure used to connect the lamp housing and / or lamp assembly and / or heat dissipation components is too narrow. When the connector in the connection structure is twisted and deformed, it will increase the difficulty of installation and the risk of air leakage, and the sealing reliability is low. In addition, the current connection structure adopts a sealing method along the optical axis direction, which requires a full circle of pressure plates for sealing, which occupies a large area of ​​the lamp housing, and the fixing parts must be evenly distributed around the pressure plates to ensure the compression amount of the sealing position of the connection structure. In some lamp housings with tight space, there is a problem that the connection structure cannot be arranged.

[0163] In the embodiment of the present application, the connector 301 in the connection structure adopts a radial sealing connection, which increases the sealing area. Even if the end of the connector 301 is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the headlight to damage the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the sum of the thickness of the first component 302 (side wall of the lamp housing), one end of the connector 301, and the second component 303 (side pressure plate of the lamp housing), and the area occupied by the lamp housing is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the headlight, taking into account the performance and reliability requirements of the headlight.

[0164] In a possible embodiment, the above connection structure further includes:

[0165] The third component 304 and the fourth component 305 .

[0166] The third component 304 is fixedly connected to the lamp group, and the fourth component 305 is fixedly connected to the lamp group. It can be understood that the third component 304 can be a side wall of the lamp group, which is integrally formed with the lamp group, and the fourth component 305 can be a side pressure plate of the lamp group, which is fixedly connected to the lamp group by fasteners such as screws and pins. The specific method of fixing the fourth component 305 with the lamp group is not limited in the embodiment of the present application.

[0167] Optionally, the lamp group may be a DLP module, which is not limited in the embodiment of the present application.

[0168] Optionally, the fourth component 305 (side pressure plate of the lamp group) can be fixedly connected to the lamp group in an L shape, in which case the lamp group body is larger than the heat dissipation component; or, the fourth component 305 (side pressure plate of the lamp group) can be fixedly connected to the lamp group in an I shape, in which case the lamp group body is the same size as the heat dissipation component; or, the fourth component 305 (side pressure plate of the lamp group) can be fixedly connected to the lamp group in other shapes, which is not limited in the present embodiment of the application. It should be noted that Figure 7 and Figure 8 The fourth component 305 (side pressure plate of the lamp assembly) is L-shaped and fixedly connected to the lamp assembly. The lamp assembly body is larger than the heat dissipation component. Figure 7 and Figure 8 This is only described as an example and should not be used to limit the embodiments of the present application.

[0169] The connecting member 301, the third component 304 and the fourth component 305 all surround the axial direction of the lamp group. It can be understood that the connecting member 301, the third component 304 and the fourth component 305 are all annular structures that surround the axial direction of the lamp group, and the annular structure can be a square ring structure, a circular ring structure, an elliptical ring structure, etc., and the embodiments of the present application do not limit this.

[0170] There is a second clamping space between the third component 304 and the fourth component 305, the other end of the connector 301 is fixed in the second clamping space, the third component 304, the other end of the connector 301 and the fourth component 305 are sequentially stacked along the radial direction of the lamp assembly, the connector 301 includes a third surface 301c and a fourth surface 301d opposite to each other along the thickness direction thereof, the third surface 301c abuts against the third component 304, and the fourth surface 301d abuts against the fourth component 305. It can be understood that the other end of the connector 301 is connected by radial sealing, so that the third component 304, the other end of the connector 301 and the fourth component 305 form a three-layer sealing connection structure with the other end of the connector 301 located in the middle, which increases the sealing area and improves the sealing reliability, and the heat dissipation component can be arranged in the annular structure formed by the connector 301, so that the heat dissipation component is arranged outside the lamp housing, and the heat dissipation component can be externalized to improve the heat dissipation efficiency of the lamp.

[0171] In the embodiment of the present application, the connector 301 in the connection structure adopts radial sealing connection, which increases the sealing area. Even if the end of the connector 301 is twisted and deformed, it does not increase the difficulty of assembly, and the sealing is guaranteed, which can improve the assembly efficiency and ensure the sealing reliability. It can effectively prevent dust and water vapor from invading the internal space of the headlight and causing damage to the lamp group and the circuit, thereby having a good lighting effect and a long service life. In addition, the occupied area is only the thickness of the third component 304 (side wall of the lamp group), the other end of the connector 301, and the fourth component 305 (side pressure plate of the lamp group) added together, and the area occupied by the lamp group is small. The fixing parts do not need to be evenly arranged, and can be arranged where space allows, which greatly improves the flexibility of adaptation and the sealing reliability. Therefore, the connection structure in the embodiment of the present application can improve the heat dissipation efficiency of the headlight, taking into account the requirements of the performance and reliability of the headlight.

[0172] In a possible embodiment, the third component 304 and the fourth component 305 are arranged on the inner side of the lamp housing opening, and the angle between the axial direction of the third component 304 and the axial direction of the lamp housing opening is a first angle, and the angle between the axial direction of the fourth component 305 and the axial direction of the lamp housing opening is a first angle.

[0173] It is understandable that the lamp housing opening and the heat dissipation component of the lamp assembly are not in the same direction and are not aligned. The lamp housing opening, the connection structure and the heat dissipation component of the lamp assembly form a special-shaped channel notch shape. Through the flexible sealing connection of the connection structure, the heat dissipation of the lamp can be achieved while ensuring the sealing of the lamp, and the position of the lamp assembly can be adjusted, thereby achieving the dimming function of the lamp, taking into account the requirements of lamp performance and reliability. In addition, the heat dissipation component of the lamp assembly is placed outside the lamp housing, which can make full use of the limited space inside the lamp and improve the utilization rate of space resources.

[0174] It should be noted that Figure 7and Figure 8 The axial direction of the third component 304 is perpendicular to the axial direction of the lamp housing opening, and the axial direction of the fourth component 305 is perpendicular to the axial direction of the lamp housing opening, that is, the first angle is 90°. Figure 7 and Figure 8 This is only described as an example and should not be used to limit the embodiments of the present application.

[0175] In a possible embodiment, the connecting member 301 includes: a connecting portion and a deformation portion.

It can be understood that the first pleated section adopts folds with transverse spiral patterns. Through the elastic deformation of the deformation part, the position of the lamp group can be adjusted while ensuring the sealing of the lamp, thereby realizing the dimming function of the lamp, taking into account the requirements of lamp performance and reliability, and the relative position relationship between the lamp housing opening and the heat dissipation components of the lamp group can be flexibly arranged, thereby improving the flexibility of adaptation and the utilization of space resources. Alternatively, the extension direction of the first pleated section can also be parallel to the axial direction of the connector 301. It can be understood that the first pleated section adopts pleats with vertical stripes, which is conducive to the removal of liquid cooling condensed water from the heat dissipation components and can improve the heat dissipation efficiency of the lamp.

[0178] In a possible embodiment, the deformation portion further includes at least one second fold segment, and the extension direction of the second fold segment is parallel to the circumference of the connecting member 301 , or the extension direction of the second fold segment is parallel to the axial direction of the connecting member 301 .

[0179] It can be understood that the deformation part includes at least one first pleat segment, and the extension direction of the first pleat segment is parallel to the circumference of the connecting piece 301. It can be understood that the first pleat segment adopts transverse spiral pleats. Through the elastic deformation of the deformation part, the position of the lamp group can be adjusted while ensuring the sealing of the lamp, thereby realizing the dimming function of the lamp, and taking into account the requirements of lamp performance and reliability. The deformation part also includes at least one second pleat segment, and the extension direction of the second pleat segment is parallel to the axial direction of the connecting piece 301. It can be understood that the second pleat segment adopts vertical stripes of pleats, which is beneficial to the removal of liquid cooling condensed water of the heat dissipation components and can improve the heat dissipation efficiency of the lamp.

[0180] Accordingly, the above Figure 7 and Figure 8 It can be seen that the embodiment of the present application also provides another heat dissipation device, which relates to the field of heat dissipation technology and can be specifically applied to vehicle lights to improve the heat dissipation efficiency of the vehicle lights while taking into account the performance and reliability requirements of the vehicle lights.
