Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted equipment, and in particular to a sealing device, a light-emitting device, a lamp, a projection device and a terminal. Background Art

[0002] Optical equipment refers to equipment that can emit or receive light beams. It is usually equipped with a light source to generate light beams or a light receiving module to receive light beams. Some optical equipment also has optical elements to transmit or reflect light beams. The light beam transmitted in the optical equipment can reach the object space through the optical component or reach the light receiving module from the object space, playing various roles such as lighting, imaging, projection, detection, imaging, and display. The light source, light receiving module, and optical element can be collectively referred to as an optical component. In optical equipment, the optical path and the space where the optical component is located usually need to be sealed. There are two main reasons: on the one hand, dust, water vapor, etc. attached to the surface of the optical component will greatly reduce the performance of the optical component. On the other hand, when dust, water vapor, etc. in the space enter the vicinity of the optical path, light will scatter, resulting in a decrease in the energy density of the light beam. These negative effects caused by dust, water vapor, etc. affect the service quality and service life of the optical equipment. Therefore, optical equipment usually needs to be equipped with a sealing device to prevent dust and water vapor from entering.

[0003] Optical equipment usually uses a compression gasket as a sealing device. The gasket is set between two parts. The two parts compress the gasket so that the three fit tightly together to achieve the purpose of dust prevention. In order to absorb the gap caused by the assembly tolerance of the parts and avoid dust prevention failure, the compression amount of the gasket is usually designed to be large. Moreover, due to the current trend of miniaturization of equipment, the thickness space left for the dustproof gasket is often very small, which leads to a high compression rate of the gasket. In some common equipment, the compression amount of the gasket is even as high as 50%. Under high compression rates, the gasket will generate great stress, which is very likely to crush the parts on both sides of the gasket, causing damage to the equipment. Summary of the invention

[0004] The present application provides a sealing device, a light-emitting device, a lamp, a projection device and a terminal, which reduce the stress generated by the sealing device when it is compressed, so that the contact interface of the sealing device can fully contact the structural parts on both sides to achieve the sealing effect, and can also extend the service life of each device.

[0005] In a first aspect, the present application provides a sealing device for sealing a gap between a first structural member and a second structural member. The sealing device comprises a main body and a protrusion, both of which are made of elastic material, and the main body is provided with a first opening, and the first opening penetrates the main body along the thickness direction of the main body. The main body also comprises a first end face and a second end face arranged oppositely, and the protrusion is protruding from the second end face and surrounds the first opening. The projection area of ​​the protrusion on the second end face is smaller than the area of ​​the second end face.

[0006] The main body is arranged between the first structural member and the second structural member, the first end surface contacts the first structural member, and the protruding portion contacts the second structural member.

[0007] In the present application, the first structural member and the second structural member apply pressure to the sealing device through the first end face and the protrusion respectively. The sealing device is compressed to produce elastic deformation so as to fit tightly against the first structural member and the second structural member. The first end face and the protrusion can fully contact the structural members on both sides to achieve a sealing effect and prevent dust, water vapor, liquid, etc. from entering, thereby improving the service quality and service life of the overall device.

[0008] Moreover, in the present application, the sealing device made of elastic material is a non-solid structure, and a protrusion is convexly provided on one side end face of the main body, and the protrusion protrudes outward to contact the second structural member, so that the sealing device forms a space outside the protrusion. Since the projection area of ​​the protrusion on the second end face is smaller than the area of ​​the second end face, under the condition of the same amount of compression, the pressure applied to the structural members on both sides by the sealing device in the present application is much smaller than the pressure applied to the structural members on both sides by a solid sealing device (for example, when the second end face directly contacts the second structural member). In other words, the sealing device provided by the present application can reduce the stress generated to the outside when compressed, can reduce the possibility of crushing the parts on both sides when the compression rate of the sealing device is large, and prolong the service life of the first structural member, the second structural member and the sealing device.

[0009] In a possible implementation of the first aspect, there is a gap between the second end face and the second structural member. In this way, the protrusion is in full contact with the second structural member on one side of the second end face, and compared with using a thicker solid sealing gasket, the present application can reduce the stress generated by the sealing device when it is compressed.

[0010] In another possible implementation of the first aspect, the number of protrusions is multiple. On the one hand, the multiple protrusions can form multiple lines of defense, further improving the sealing performance. On the other hand, the multiple protrusions can also increase the friction coefficient between the sealing device and the second structural member, thereby improving stability. In addition, in some schemes, the cavity formed in the middle of the multiple protrusions can form a negative pressure when compressed, so that the sealing device can fully contact the second structural member, thereby improving the sealing effect.

[0011] In another possible implementation of the first aspect, the protrusion includes a connecting end and a free end, the connecting end is connected to the second end face, and the free end extends in a direction away from the second end face. Further, the free end and the second end face form an angle. In this way, the inclined protrusion generates less stress when subjected to the same amount of compression, which can further reduce the possibility of crushing parts on both sides of the sealing device.

[0012] In another possible implementation of the first aspect, the free end includes a third end surface, and the third end surface is in contact with the second structural member. In this way, the second structural member can be in surface contact with the sealing device, which can balance the force and have better sealing performance.

[0013] In another possible implementation of the first aspect, a wave structure is provided on the main body, and the protrusion is a wave crest of the wave structure on the second end face side. In this way, the protrusion in the form of a wave crest can reduce the stress generated by the sealing device when it is compressed. In addition, the top of the wave crest is usually in an arc shape, so the contact with the structural member is smoother, and the deformation can be more regular and uniform when compressed. In some cases, the wave-shaped contact interface is not easy to generate bubbles when compressed, which can improve the sealing performance.

[0014] In another possible implementation of the first aspect, the main body is provided with a recessed portion on the first end face side, the recessed portion on the first end face side corresponds to the protruding portion on the second end face side, forming a wave structure. The first end face contacting the first structural member includes: a portion of the first end face other than the recessed portion contacts the first structural member.

[0015] By means of the corrugated structure with corresponding concave and convex parts, the elastic material of the main body of the sealing device can be further reduced, thereby further reducing the stress generated externally when subjected to the same amount of compression.

[0016] In another possible implementation of the first aspect, the main body includes a connecting portion and a sealing portion, and the connecting portion and the sealing portion are connected at an angle. The first opening is provided at the connecting portion, and the first end surface and the second end surface are located at opposite sides of the sealing portion.

[0017] The connection part can facilitate the installation and fixation of the sealing device, thereby preventing the sealing device from slipping and improving the sealing performance. Especially for the sealing device installed in the mobile terminal, due to the complex travel environment, it is often subject to vibration and bumps. By setting the connection part, the stability of the structure can be improved and the service life of the whole device can be extended.

[0018] In another possible implementation of the first aspect, a positioning portion is further provided on the main body. The positioning portion can improve the installation efficiency of the sealing device, and can also play a role in fixing the sealing device, reducing the possibility of large displacement due to deformation, preventing the sealing device from slipping, and improving the sealing performance.

[0019] Furthermore, a positioning structure corresponding to the positioning portion is provided on the first structural member and / or the second structural member.

[0020] In yet another possible implementation of the first aspect, the positioning portion is a positioning hole, and the positioning hole penetrates the main body along a thickness direction of the main body.

[0021] In a second aspect, the present application further provides a device comprising a first structural member, a second structural member and the sealing device described in any one of the first aspects, wherein a gap is provided between the first structural member and the second structural member.

[0022] In a possible implementation of the second aspect, the device is a device arranged in a mobile terminal, such as a vehicle-mounted device. Since the mobile terminal travels in a complex environment and is often subjected to vibration and bumps, by setting a method to reduce the stress generated outward by the sealing device, the peak value of the stress generated in scenes such as vibration and bumps can be reduced, thereby extending the service life of the vehicle-mounted device.

[0023] In a possible implementation manner of the second aspect, the apparatus may be an optical device or included in an optical device.

[0024] In another possible implementation of the second aspect, the device is a light-emitting device, or a device that can emit light.

[0025] Exemplarily, the first structural member is an optical component, or the second structural member is an optical component. Further exemplary, the second structural member is a fixing member for installing the optical component, or the first structural member is a fixing member for installing the optical element.

[0026] The optical component is used to generate a light beam, and the fixing member is provided with a second opening, and the second opening penetrates the fixing member along the thickness direction of the fixing member. The optical component is used to generate or propagate a light beam, and the light beam passes through the first opening and the second opening on the main body of the sealing device.

[0027] The fixing member may include one or more components such as a mounting bracket, a housing, or a support plate.

[0028] In yet another possible implementation manner of the second aspect, the first structural member and the second structural member apply pressure to the sealing device, and the sealing device is elastically deformed by the pressure and is in close contact with the first structural member and the second structural member.

[0029] In another possible implementation of the second aspect, the optical component includes a first surface, a second surface and a side wall surface, along the thickness direction of the optical component, the first surface and the second surface are arranged opposite to each other, and the side wall surface is connected between the first surface and the second surface. The protrusion of the sealing device is arranged between the first surface and the fixing member.

[0030] The sealing device in the above embodiment can reduce the stress on the first surface of the optical component.

[0031] In another possible implementation of the second aspect, the optical component includes a first surface, a second surface and a side wall surface. Along the thickness direction of the optical component, the first surface and the second surface are arranged back to back, the side wall surface is connected between the first surface and the second surface, and the protrusion of the sealing device is arranged between the first side wall and the fixing member.

[0032] In the above embodiment, the compressed portion of the sealing device may be located between the first side wall and the fixing member. The sealing device of the present application may reduce the stress on the optical component on the first side surface and avoid crushing the optical component in the side wall direction.

[0033] Furthermore, the first surface may not be subjected to stress or the compression amount of the first surface may be designed to be relatively small, thereby reducing the pressure on the first surface. In particular, in the case where a stress-sensitive component may be set in the first surface, the present application transfers the compression part to the side wall, which can significantly reduce the stress on the first surface and avoid the sealing device from crushing the optical component in the direction of the first surface.

[0034] In another possible implementation of the second aspect, the main body of the sealing device includes a connecting portion and a sealing portion, the connecting portion is located between the first surface and the fixing member, the sealing portion is located between the side wall and the fixing member, and the protrusion of the sealing device is arranged on the sealing portion.

[0035] Optionally, the thickness of the connecting portion is smaller than the thickness of the sealing portion, and / or the compression amount of the connecting portion is smaller than the compression amount of the sealing portion.

[0036] In yet another possible implementation of the second aspect, the optical component is an array light source, an optical fiber array, or a spatial light modulator (SLM).

[0037] Exemplarily, the optical component is a light source circuit board. In another exemplary embodiment, the array light source may be a laser array. In another exemplary embodiment, the array light source may be a light-emitting diode (LED) array.

[0038] Exemplarily, the SLM includes a digital micro-mirror device (DMD). Optionally, the DMD may also be replaced by a DMD chip.

[0039] Optionally, the optical component may include one or more optical elements such as a lens or a reflector. In some embodiments, the optical component may include a display element such as a liquid crystal display (LCD) or liquid crystal on silicon (LCOS).

[0070] Most devices are assembled from multiple parts, and there will be gaps between the parts when they are assembled, or there will be installation tolerances between the parts. If there is no sealing device, external dust, water vapor, etc. will enter the device and affect the normal function of the device.

[0071] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a lamp. Figure 2 yes Figure 1 The local structure diagram of the lamp in the dotted box area is shown. The light source circuit board 101 is installed in combination with the structural member 102. The light beam emitted by the light source circuit board 101 passes through the opening in the structural member 102, and optionally passes through other optical elements, such as the transparent window 103, to reach the object space to achieve the lighting effect. As an example of the installation method between the light source circuit board 101 and the structural member 102, the fastener 106 can be inserted into the first connecting hole 1051 on the support plate 105 and the second connecting hole 1021 on the structural member 102, so as to achieve the purpose of fixing and assembling the light source circuit board 101 and the structural member 102.

[0072] Furthermore, by providing the sealing gasket 104, the assembly tolerance between the light source circuit board 101 and the structural member 102 can be absorbed, and dust, water vapor, etc. can be prevented from entering the interior of the lamp, thereby extending the service life of the lamp. In order to absorb the gap caused by the assembly tolerance of the parts and avoid dustproof failure, the compression amount of the sealing gasket is usually designed to be large. At the same time, due to the current trend of miniaturization of equipment, the thickness space left for the dustproof gasket is often very small, which leads to a high compression rate of the sealing gasket.

[0073] like Figure 3 As shown, the thickness of the sealing gasket 104 in the natural state is d 1After the light source circuit board 101 and the structural member 102 are assembled, the thickness is compressed to d due to the extrusion at both ends. 2 In some common devices, the compression of the gasket, i.e. Usually it is relatively large, even up to 50%. Under high compression rate, the sealing gasket 104 will generate great stress on the surface of the light source circuit board 101 and the surface of the structural member 102, and this stress is very likely to crush the parts on both sides of the sealing gasket, causing damage to the equipment.

[0074] Especially for stress-sensitive devices, such as capacitors, waveguides, circuits, liquid crystal elements, microlenses, etc., the stress generated by the sealing gasket, when acting on the stress-sensitive surface, is very likely to cause the stress-sensitive device to malfunction, thereby causing the entire device to malfunction.

[0075] In view of this, the embodiment of the present application provides a sealing device, which can reduce the stress generated by the sealing device when it is compressed, so that the contact interface of the sealing device can fully contact the parts on both sides to achieve the sealing effect, and can also extend the service life of each component. Furthermore, the present application also provides a light-emitting device, a lamp, a projection device and a terminal having the sealing device.

[0076] The sealing device provided in the embodiment of the present application is first introduced below.

[0077] See also Figure 4 and Figure 5 , Figure 4 is a schematic diagram of a three-dimensional structure of a sealing device according to an embodiment of the present application, Figure 5 yes Figure 4 The sealing device 20 is a schematic structural diagram of a section taken along line AA. The sealing device 20 comprises a main body 201 and a protrusion 202. The main body 201 is provided with a first opening 203, along the thickness direction of the main body 201 (e.g. Figure 4 The first opening 203 penetrates the main body 201 . The main body 201 includes a first end surface 204 and a second end surface 205 that are opposite to each other. The protrusion 202 is protruded from the second end surface 205 and surrounds the first opening 203 .

[0078] When the sealing device can be arranged between structural members with a gap, the assembly of the two structural members can compress the sealing device 20, so that the first end face 204 and the protrusion 202 are in close contact with the two structural members, thereby achieving a sealing effect, such as dustproof, water vapor proof and the like.

[0079] Furthermore, the projection area of ​​the protrusion 202 on the second end surface 205 is smaller than the area of ​​the second end surface 205. Figure 6 When the sealing device 20 is squeezed by the structural members on both sides, its thickness is increased from d 3 (Under natural conditions) compressed to d4 However, since the sealing device 20 is a non-solid structure with a protruding portion, under the same compression amount, for example, the compression rate is 50%, the stress applied to the structural members on both sides by the sealing device 20 provided in the embodiment of the present application is much less than that of the solid sealing device ( Figure 3 The sealing gasket 104 shown in FIG. 1 applies stress to the structural members on both sides.

[0080] Combine the following Figures 5 to 10 , two possible designs of some sealing devices provided in the embodiments of the present application are introduced:

[0081] Design 1: The protrusion 202 includes a connecting end 2021 and a free end 2022. Figure 5 The connecting end 2021 is connected to the second end face 205, and the free end 2022 extends in a direction away from the second end face 205. In short, the protrusion protrudes outward, thereby forming a space outside the protrusion, reducing the stress generated by the sealing device when receiving the same amount of compression.

[0082] In a possible implementation manner, the free end 2022 forms an angle with the second end surface 205. Figure 7 , Figure 7 2 is a schematic diagram of the structure of another sealing device provided in an embodiment of the present application, wherein the angle between the free end 2022 and the second end face 205 is α, α<90°. In one possible case, when the sealing device 20 is squeezed, the direction of the stress can be transmitted along the inclined free end 2022, so that the stress in the direction perpendicular to the second end face 205 is smaller.

[0083] In one possible implementation, combining Figure 7 and Figure 8 The free end 2022 may further include a third end surface 2023. In this way, the structural member on one side of the protrusion 202 may be in surface contact with the sealing device, which can balance the force and have better sealing performance.

[0084] In one possible implementation, combining Figure 8 The end of the free end is a contact platform, and the contact platform includes a third end surface 2023. By providing the contact platform, the area of ​​the third end surface 2023 can be increased, thereby increasing the contact surface, so that it plays a role of balancing the force when compressed, and has better sealing performance.

[0085] Design 2: a wave structure is provided on the main body 201, and the protrusion 202 is the crest of the wave structure on the second end surface 205 side. Fig. 9As shown, the main body 201 includes a plurality of protruding wave crests on the second end face 205 side to form a wave structure. The top of the wave crest can be arc-shaped, so that the contact surface with the structural member is smoother and the deformation can be more regular and uniform when compressed. In some cases, the wave-shaped contact interface is less likely to generate bubbles when compressed, which can improve the sealing performance.

[0086] In a possible implementation manner, the main body 201 is provided with a recessed portion 206 on the side of the first end surface 204. Fig.10 The concave portion 206 on the first end face 204 corresponds to the convex portion 202 on the second end face 205, forming a wave structure. The wave structure with corresponding concave and convex portions can further reduce the elastic material of the main body of the sealing device, thereby further reducing the stress generated to the outside when subjected to the same amount of compression.

[0087] The above two designs are exemplary designs made to facilitate understanding of the scheme, and there may be more possible designs in the specific implementation. In addition, the various possible schemes of the present application may be combined, for example, in a structure where the concave and convex parts correspond to each other, a contact platform may be provided at the end of the protruding part, etc. The combination will not be described one by one here.

[0088] In some possible implementations, there may be multiple protrusions 202. Further, when there are multiple protrusions 202, the shapes and sizes of the multiple protrusions 202 may be the same or different.

[0089] For example, Fig.10 As shown, the sealing device 20 may be provided with two protrusions 202 on the second end surface 205 .

[0090] As another example, the sizes of the multiple protrusions 202 can be different. For example, in the direction perpendicular to the second end face, the height of the protrusion 202 close to the first opening 203 is greater than the height of the protrusion 202 away from the first opening 203. In this way, the multiple protrusions 202 can form multiple lines of defense and reduce the stress of the sealing device 20 under the same compression amount.

[0091] As another example, the shapes of the plurality of protrusions 202 may be different, so that a variety of possible combination designs may be used in the sealing device to improve the sealing performance.

[0092] In some possible implementations, a positioning portion is further provided on the main body 201. Furthermore, a positioning structure corresponding to the positioning is provided on at least one of the structural members on both sides of the sealing device 20. Exemplarily, the positioning portion is a positioning hole, which penetrates the main body along the thickness direction of the main body, and a positioning pin is provided on one side of the structural member, which can be inserted into the positioning hole to fix the sealing device, reduce the possibility of displacement due to deformation, avoid slipping of the sealing device, and improve the sealing performance.

[0093] In the aforementioned Figure 4-Figure 10 The illustrated embodiment is introduced by taking the first end face 204 and the second end face 205 as two opposite sides along the penetration direction of the first opening 203 as an example. In a specific implementation, the positional relationship between the first end face 204 and the second end face 205 can have other designs. For example, the first end face 204 and the second end face 205 are two opposite sides perpendicular to the penetration direction of the first opening 203, and this design is introduced as an example below. It should be noted that some of the aforementioned possible designs, such as one or more possible designs of the shape of the protrusion 202, the number of the protrusions 202, or the design of the positioning portion, etc., can also be applied in the following embodiments.

[0094] See also Fig.11 and Fig.12 , Fig.11 is a schematic diagram of a three-dimensional structure of a sealing device according to an embodiment of the present application, Fig.12 yes Fig.11 The sealing device 20 is a schematic structural diagram of a section taken along line BB. The sealing device 20 comprises a main body 201 and a protrusion 202. The main body 201 is provided with a first opening 203, which is formed along the thickness direction of the main body 201 (e.g. Fig.11 The first opening 203 penetrates the main body 201. The main body 201 includes a first end face 204 and a second end face 205 that are oppositely disposed. The protrusion 202 is protruded from the second end face 205 and surrounds the first opening 203. Fig.11 and Fig.12 In the illustrated embodiment, the first end surface 204 and the second end surface 205 are two end surfaces that are arranged in a direction perpendicular to the penetration direction of the first opening 203 , that is, perpendicular to the z direction, and are opposite to each other.

[0095] In one possible implementation, see Fig.13The main body 201 includes a connecting portion 2011 and a sealing portion 2012, and the connecting portion 2011 and the sealing portion 2012 are connected at an angle. The first opening 203 is provided at the connecting portion 2011, and the first end face 204 and the second end face 205 are located on opposite sides of the sealing portion 2012. The connecting portion 2011 can facilitate the installation and fixation of the sealing device 20, and its thickness (i.e., the thickness in the Z direction) can be set relatively small, thereby further reducing the force on the structural members on both sides in the Z direction (described below), and the connecting portion 2011 may not even contact with the structural members on one side, or even with the structural members on both sides. The sealing portion 2012 can be compressed and in close contact with the structural members on both sides to play a sealing role.

[0096] Optionally, the thickness of the connecting portion 2011 is smaller than the thickness of the sealing portion 2012. Alternatively, when the sealing device is compressed by the structural members on both sides, the compression amount of the connecting portion 2011 is smaller than the compression amount of the sealing portion 2012.

[0097] The aforementioned sealing device 20 can be used to seal the gap between two structural members. The following is an introduction using the two structural members as a first structural member and a second structural member as an example. For the sake of distinction, in the present embodiment, the structural member to which the first end face 204 faces is referred to as the first structural member, and the structural member to which the second end face 205 faces is referred to as the second structural member.

[0098] For some possible implementations, see Fig.14 and Fig.15 , Fig.14 is a schematic diagram of the exploded structure of a device provided in an embodiment of the present application, Fig.15 2 is a schematic diagram of a structure of a device provided in an embodiment of the present application. The main body 201 of the sealing device 20 is disposed between the first structural member 30 and the second structural member 40, the first end face 204 contacts the first structural member 30, and the protrusion 202 contacts the second structural member 40. It can be seen that the first structural member 30 and the second structural member 40 apply pressure to the sealing device through the first end face 204 and the protrusion 202 respectively, and the sealing device is compressed to produce elastic deformation so as to be tightly attached to the first structural member 30 and the second structural member 40. Fig.15 The dark part at the top of the protrusion 202 is used to represent the part that generates elastic deformation when compressed. Since the sealing device 20 generates elastic force outward when compressed, it fully contacts the first structural member 30 and the second structural member 40, which can prevent dust, water vapor, etc. from entering, thereby improving the service quality and service life of the equipment.

[0099] Since the projection area of ​​the protrusion 202 on the second end face 205 is smaller than the area of ​​the second end face 205, the external stress generated when the sealing device 20 is compressed can be reduced, and the possibility of crushing the parts on both sides when the compression rate of the sealing device is large can be reduced, thereby extending the service life of the first structural member 30, the second structural member 40 and the sealing device 20.

[0100] Optionally, there is a gap between the second end surface 205 and the second structural member 40, that is, there is a cavity portion in the middle. Fig.15 The protrusion 202 fully contacts the second structural member 40 on one side of the second end face 205, rather than the solid end face directly contacting the second structural member 40, which can reduce the stress generated by the sealing device when it is compressed.

[0101] In a possible implementation, the second structural member 40 may be a panel 50, the panel 50 includes a first surface 501, a second surface 502 and a side wall surface 503, along the thickness direction of the panel 50, the first surface 501 and the second surface 502 are arranged opposite to each other, and the side wall surface 503 is connected between the first surface 501 and the second surface 502. The protrusion 202 of the sealing device 20 is arranged between the first surface 501 and the first structural member 30.

[0102] In some embodiments, the panel 50 is more sensitive to stress acting on the first surface 501. For example, the length (or width) of the first surface is greater than the thickness of the second structural member. When external force acts on the first surface 501, it may be deformed greatly because it is relatively thin in the thickness direction.

[0103] In some solutions, the panel 50 may be provided with stress-sensitive components, such as one or more components such as circuits, capacitors, resistors, waveguides, and liquid crystal elements. When the force acting on the first surface 501 is large, the panel 50 may be crushed. However, through the embodiment of the present application, the stress generated by the sealing device 20 when compressed can be reduced, so that the stress on the panel 50 is reduced, which is conducive to the normal operation of the components on the panel 50, thereby extending the service life of the panel 50. Similarly, the stress on the first structural member 30 is also reduced, which can reduce the possibility of the first structural member 30 being crushed and extend its service life.

[0104] In some possible cases, the panel 50 is an optical component, including but not limited to one or more of an array light source, a light source circuit board, an optical fiber array, a spatial light modulator (SLM), an optical element, a light receiver, or a display element. Among them, the array light source can be a laser array. In another exemplary embodiment, the array light source can be a light-emitting diode (LED) array. The SLM includes a digital micro-mirror device (DMD). Among them, the DMD can also be replaced by a DMD chip. In another exemplary embodiment, the optical element is such as a lens, a reflector, a composite glass panel, or a window. In another exemplary embodiment, the light receiver is such as an avalanche photodiode array, a single photonavalanche diode (SPAD) array, a complementary metal oxide semiconductor (CMOS, a photosensitive element), or a charge-coupled device (CCD). As another example, the display element is a liquid crystal display (LCD) or liquid crystal on silicon (LCOS).

[0105] Exemplary, combined Fig.15 The panel 50 can generate a light beam, for example, the panel 50 can be a DMD chip or a light source circuit board. The light beam generated by the panel 50 can pass through the first opening 203 on the main body of the sealing device 20. The sealing device 20 can prevent dust, water vapor, etc. from entering the end face of the light beam emitted by the panel 50 and the light beam passing through the optical path, thereby improving the energy density of the emitted light beam. At the same time, the sealing device 20 can also reduce the stress on the panel 50, maintain the normal operation of the panel 50, and extend its service life.

[0106] As another example, the panel 50 can be used to receive a light beam, such as a SPAD array. Accordingly, the light beam can pass through the first opening 203 to reach the panel 50, and the sealing device can seal and reduce the stress on the SPAD array, thereby extending the service life.

[0107] In some other possible cases, the panel 50 may be an integrated circuit board, such as a chip, such as a central processing unit or a microprocessor.

[0108] In a possible implementation, the first structural member 30 is a fixing member 60, and the fixing member 60 can be used to install the panel 50. Optionally, the fixing member 60 can include a second opening 601. In the case where the panel 50 is an optical component, the light beam passing through the panel 50 can pass through the second opening 601, such as Fig.15 shown.

[0109] Optionally, the fixing member 60 may include one or more components such as a mounting bracket, a housing, or a support plate.

[0110] For some possible implementations, see Fig.16 and Fig.17 , Fig.16 is a schematic diagram of the exploded structure of another device provided in an embodiment of the present application, Fig.17 yes Fig.16 The structural diagram of the device shown in FIG. The main body 201 of the sealing device 20 is disposed between the first structural member 30 and the second structural member 40, the first end face 204 contacts the first structural member 30, and the protrusion 202 contacts the second structural member 40. It can be seen that the second structural member 40 and the first structural member 30 apply pressure to the sealing device 20 through the first end face 204 and the protrusion 202 respectively, and the sealing device 20 is compressed to produce elastic deformation so as to be closely attached to the first structural member 30 and the second structural member 40. Fig.17 The dark part at the top of the protrusion 202 is used to represent the part that generates elastic deformation when compressed. Since the sealing device 20 generates elastic force outward when compressed, it can fully contact the first structural member 30 and the second structural member 40, which can prevent dust, water vapor, etc. from entering, thereby improving service quality and service life.

[0111] Optional, in Fig.16 and Fig.17 In the illustrated embodiment, the first structural member 30 may be a panel 50, the panel 50 comprising a first surface 501, a second surface 502 and a side wall surface 503, along the thickness direction of the panel 50, the first surface 501 and the second surface 502 are disposed opposite to each other, and the side wall surface 503 is connected between the first surface 501 and the second surface 502. The protrusion 202 of the sealing device 20 is disposed between the side wall surface 503 and the first structural member 30.

[0112] In some cases, the panel 50 is more sensitive to the stress acting on the first surface 501, so the side wall surface 503 is used to bear the stress generated when the sealing device 20 is compressed, so as to prevent the first surface 501 from being crushed due to the large stress, thereby achieving the sealing effect and ensuring the normal operation of the panel 50, thereby improving the service life of the panel 50. Similarly, the stress on the second structural member 40 is also reduced, which can reduce the possibility of the second structural member 40 being crushed and extend its service life.

[0113] It should be understood that the possible embodiments of the sealing device 20 described above may be different from those of Figure 14-17 Possible design combinations of the devices shown.

The panel 50 and the fixing member 60 apply pressure to the sealing device 20, and the sealing device 20 is elastically deformed by the pressure and is in close contact with the panel 50 and the fixing member 60 to achieve a dustproof effect. The structure of the sealing device and its possible design are described above and will not be described here one by one.

[0118] The fixing member 60 is provided with a second opening 601, which penetrates the fixing member 60 along the thickness direction of the fixing member 60. The first opening 203 and the second opening 601 overlap in the propagation direction of the light beam, so that the light beam emitted from the panel 50 can pass through the first opening 203 and the second opening 601.

[0119] In the light-emitting device 70 provided in the embodiment of the present application, the structural design of the sealing device 20 can reduce the stress generated to the outside when it is compressed, so that the contact interface of the sealing device 20 can fully contact the panel 50 and the fixing part 60 on both sides of the gap to achieve a sealing effect, and can also extend the service life of each component in the light-emitting device 70.

[0120] Optionally, the panel 50 includes a light-emitting end 504, which is protruding and can be replaced by a light-transmitting surface, a light-transmitting window, etc. The light-emitting end 504 can be embedded in the first opening 203, and the protrusion 202 surrounding the first opening 203 can reduce the adhesion of dust, water vapor, etc. to the light-emitting end 504, and can also reduce the possibility of dust, water vapor, etc. drifting on the light path, thereby improving the energy and quality of the light beam emitted by the light-emitting device 70.

[0124] Optionally, the positioning hole 207 and the mounting hole 208 can be arranged together. For example, the mounting hole 208 not only accommodates the second connection structure 603 to achieve fixed assembly of the first connection structure 505 and the second connection structure 603, but also plays a positioning role to facilitate the installation of the sealing device 20.

By designing the wave structure, the stress generated to the outside when the sealing device 20 is compressed can be reduced, and the possibility of crushing the parts on both sides when the compression rate of the sealing device is large can be reduced, thereby extending the service life of the first structural member, the second structural member and the sealing device.
