Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle display, in particular to a curved mirror assembly, a vehicle display system and a vehicle BACKGROUND

[0002] At present, in the vehicle display system, the curved mirror needs to be fixed on the support, and then fixed in the vehicle or other vehicles. Since the stress points of the connection position between the curved mirror and the support are concentrated, the current connection mode of the curved mirror and the support is easy to cause slight deformation of the curved mirror, and then cause deviation of the reflected light path of the curved mirror, resulting in unclear image of the vehicle display system, and bringing bad user experience. CONTENT OF THE UTILITY MODEL

[0003] The embodiments of the present application provide a curved mirror assembly, a vehicle display system and a vehicle, which can avoid excessive stress during the connection of the curved mirror and the shell, thereby avoiding deviation of the reflected light path of the curved mirror.

[0004] In the first aspect, the present application provides a curved mirror assembly, comprising a shell and a curved mirror. The shell comprises a shell body and a first welding part, the shell body is provided with a cavity and a mounting opening, the mounting opening penetrates the shell and is in communication with the cavity, and the first welding part is connected to the edge of the mounting opening. The curved mirror comprises a curved mirror body and a second welding part, the second welding part is connected to the edge of the curved mirror body, and the second welding part is connected with the first welding part through a welding process, so that the curved mirror body covers the mounting opening.

[0005] In the present embodiment, the shell and the curved mirror are connected by welding. For example, under the high temperature of laser welding, the first welding part of the shell and the second welding part of the curved mirror are melted under the high temperature, the melted first welding part and the melted second welding part are in contact (direct contact or indirect contact) and re-solidified into one body.

[0006] The laser welding technology has extremely high heating and cooling speed, which means that the first welding part and the second welding part can quickly reach the required temperature for welding during the welding process, and quickly cool down after the welding is completed. This rapid heating and cooling process greatly reduces the thermal stress generated in the welding process of the curved mirror. The reduction of thermal stress helps to maintain the shape stability and structural integrity of the curved mirror, avoids the change of the surface shape of the curved mirror, and the stable surface shape of the curved mirror can reduce the frequency of replacement due to breakage, thereby reducing the maintenance cost. The stable curved mirror can ensure the clarity and accuracy of the projected information, provide more intuitive and easy-to-read information for the user, and improve the riding experience.

[0007] In addition, laser welding is a non-contact processing method, which means that during the welding process, the laser beam directly acts on the welding area (the first welding part and the second welding part) without the need for direct contact with the mirror body. This non-contact processing method reduces the vibration stress caused by mechanical contact. The reduction of vibration stress helps to prevent the mirror body from deforming or being damaged during welding, and ensures the quality and strength of the mirror and the shell.

[0008] In one possible implementation, along the thickness direction of the curved mirror, the projection of the second welding part on the shell body is misaligned with the first opening.

[0009] Wherein, misaligned means that the projection of the second welding part on the shell body is completely misaligned with the first opening.

[0010] In this embodiment, the second welding part does not occupy the light transmission position of the first opening, thereby avoiding the second welding part from blocking the reflecting surface of the mirror body.

[0011] In one possible implementation, the curved mirror is further provided with a light transmission piece. The first welding part and the second welding part are adjacently arranged, and the light transmission piece is located on the side of the first welding part and the second welding part away from the cavity and covers at least part of the first welding part and at least part of the second welding part. The light transmission piece is connected with the first welding part and the second welding part through a welding process.

[0012] In this embodiment, when the first welding part and the second welding part are welded, the required welding position can also be covered by the light transmission piece. The laser beam can pass through the light transmission piece to reach the surface of the first welding part and the second welding part. Under the action of the laser beam, the first welding part and the second welding part melt, and the melted first welding part and the second welding part can be in contact with the light transmission piece and connected with the light transmission piece after cooling and solidification.

[0013] By adding an additional light transmission piece, additional support and protection are provided for the entire welding area, improving the stability and safety of the overall structure of the curved mirror assembly. The light transmission piece can disperse the stress borne by the welding position and reduce the risk of damage to the welding position due to stress concentration. The light transmission piece can effectively isolate air, moisture and other corrosive media, preventing the welding position from being corroded, thereby prolonging the service life of the curved mirror assembly. In some application scenarios, the welding position may be subject to wear and tear. The addition of the light transmission piece can significantly reduce wear and tear and maintain the integrity of the curved mirror assembly. Maintaining the shape stability and structural integrity of the curved mirror avoids changes in the surface shape of the curved mirror, and the stable curved mirror can ensure the clarity and accuracy of the projected information, providing users with more intuitive and easy-to-read information and improving the ride experience.

[0014] In a possible implementation, the curved mirror assembly is provided with a welding line, the welding line is located on the side of the first welding portion and the second welding portion away from the cavity, and the light-transmitting member covers the welding line.

[0015] In the embodiment, when the welding line extends from the first welding portion to the second welding portion, the molten part of the first welding portion can be in contact with the molten part of the second welding portion, the molten areas are mixed at the molecular level, and thus the first welding portion and the second welding portion are tightly connected and integrated when cooled and solidified.

[0016] In a possible implementation, the welding line includes a plurality of convex portions and a plurality of concave portions, two adjacent convex portions are connected by a concave portion, the plurality of convex portions are located in one of the first welding portion and the second welding portion, and the plurality of concave portions are located in the other of the first welding portion and the second welding portion.

[0017] In a possible implementation, the light-transmitting member is connected with the housing body to form an integrated structure.

[0018] In the embodiment, the light-transmitting member can be integrally formed with the housing body by, for example, integral injection molding. The integral molding technology integrates the originally dispersed assembly processes of the light-transmitting member and the housing, thereby reducing the production steps.

[0019] In addition, the integral molding of the light-transmitting member and the housing can also increase the connection strength of the light-transmitting member and the housing, so that the connection of the light-transmitting member and the housing is more stable, the impact resistance of the light-transmitting member is improved, and the influence of external force on the welding positions of the first welding portion and the second welding portion is dispersed to a greater extent, thereby improving the stability of the connection of the curved mirror and the housing. The stable curved mirror can ensure the clarity and accuracy of the projected information, provide more intuitive and readable information for the user, and improve the riding experience.

[0020] In a possible implementation, the light-transmitting member is connected with the curved mirror to form an integrated structure.

[0021] In a possible implementation, the first welding portion includes a first connecting surface, the second welding portion includes a second connecting surface, and the first connecting surface is oppositely arranged with the second connecting surface. The first connecting surface is curved, the second connecting surface is curved, and the first connecting surface is arranged in abutment with the second connecting surface.

[0022] In the embodiment, when the first connecting surface and the second connecting surface are curved, the contact surface of the first connecting surface and the second connecting surface is large, the first connecting surface and the second connecting surface are in molten contact, and the welding area connected after cooling and solidification is also large. The large welding area can provide more connection points, thereby increasing the strength and stability of the connection. The increase of the welding area can also disperse stress and reduce the connection failure of the curved mirror and the housing caused by concentrated stress.

[0023] In one possible implementation, both the first weld and the second weld are made of plastic.

[0024] Secondly, this application provides an in-vehicle display system, which includes an imaging device and a projection device as described above. The imaging device is capable of receiving light emitted by the projection device to form an image.

[0025] In one possible implementation, the housing is provided with a light-transmitting hole that penetrates the housing and communicates with the cavity. The light-transmitting hole and the mounting opening are spaced apart. The image light emitted by the optical engine can pass through the light-transmitting hole and be incident on the curved mirror body. The curved mirror body can receive the image light and form an image.

[0026] Thirdly, this application also provides a vehicle, including the in-vehicle display system described above. Attached Figure Description

[0040] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in other ways different from those described herein, and therefore the present application is not limited to the following embodiments.

[0041] For the convenience of understanding, the terms involved in the embodiments of the present application are first explained.

[0042] Multiple: refers to two or more than two.

[0043] Connection: should be understood in a broad sense, for example, A and B are connected, which can be that A and B are directly connected, or A and B are indirectly connected through an intermediate medium.

[0044] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0045] Please refer to Figure 1 , Figure 1 is a structural schematic view of a vehicle 100 provided by the embodiments of the present application. Among them, the vehicle 100 in the embodiments of the present application can be a known vehicle 100 such as a car, an airplane, a ship, a rocket, etc., and can also be a new vehicle 100 that will appear in the future. Among them, the car can be an electric car, a fuel car or a hybrid car, for example, a pure electric car, a range-extended electric car, a hybrid electric car, a fuel cell car, a new energy car, etc., which is not limited by the present application. The following will be described taking the vehicle 100 as a vehicle as an example.

[0046] The vehicle 100 includes a vehicle body 10 and a vehicle display system 20. The vehicle display system 20 is installed in the vehicle body 10.

[0047] The installation position of the vehicle display system 20 can be installed on an instrument panel (IP) table of the vehicle 100, or installed on a seat of the vehicle 100. Among them, the seat can include multiple rows, for example, include front-row seats arranged opposite to the front and rear-row seats arranged opposite to the rear.

[0048] It should be noted that, Figure 1 The purpose is only to schematically describe the connection relationship between the vehicle body 10 and the vehicle display system 20, and not to specifically limit the connection position, specific structure and number of each device. The structure schematically shown in the embodiments of the present application does not constitute a specific limitation on the vehicle 100. In other embodiments of the present application, the vehicle 100 can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangements.

[0049] Among them, the vehicle display system 20 can be a light field display screen.

[0050] At present, the vehicle entertainment display presents a large screen and multi-screen trend, but there are still small frame, easy to car sickness and eye pain and other pain points. The light field display screen of the embodiments of the present application can realize large frame, depth of field and long distance experience in a small volume space. The light field display is designed through a spatial optical system, so that the screen is relatively close to the human eye, but the actual imaging distance is relatively far from the human eye, thereby avoiding the influence of external light and maintaining the image clear and sharp.

[0051] Please refer to Figure 2 , Figure 2 is Figure 1 The vehicle display system 20 shown in part of the structure schematic diagram. The vehicle display system 20 includes a light machine 21 and a curved mirror assembly 22, the light machine 21 is used for emitting image light, the image light transmits in the optical path between the light machine 21 and the curved mirror assembly 22, and is reflected on the curved mirror surface of the curved mirror assembly 22.

[0052] At present, in the vehicle display system, the curved mirror needs to be fixed on the support, so as to be fixed in the vehicle and the like. Because the connection position of the curved mirror and the support is relatively concentrated, the curved mirror will be slightly deformed after assembly, and then the reflection light path of the curved mirror to the light will be deviated, so that the image of the vehicle display system is not clear, and the user brings bad use experience.

[0053] Based on this, please refer to Figure 3 , Figure 3 is Figure 2An exploded schematic view of the curved mirror assembly 22 is shown. By adjusting the structure of the curved mirror assembly 22, the present application avoids the occurrence of excessive concentrated stress in the process of connecting the curved mirror of the curved mirror assembly with the housing, thereby avoiding the deviation of the reflection light path of the curved mirror.

[0054] The curved mirror assembly 22 includes a housing 221 and a curved mirror 222. The curved mirror 222 can be fixedly connected with the vehicle body 10 through the housing 221.

[0055] Referring to Figure 3 , Figure 3 is Figure 2 a structural schematic view of the housing 221. The housing 221 includes a housing body 223 and a first welding portion 224. The housing body 223 and the first welding portion 224 are integrally formed. The first welding portion 224 is a portion of the housing 221 that is melted and solidified during welding.

[0056] The housing body 223 is provided with a cavity 2231, a mounting opening 2232, a light engine accommodating groove 2233, and a light output port 2234. The opening of the cavity 2231 on the surface of the housing body 223 facing the Z direction is the mounting opening 2232. The opening of the cavity 2231 on the side of the housing body 223 opposite to the Z direction is the light output port 2234. The light output port 2234 of the housing body 223 penetrates the housing body 223 and communicates with the cavity 2231. The cavity 2231 is used to provide a light path space for the propagation of image light. The mounting opening 2232 can expose the curved mirror 222, so that the image light can be transmitted to the curved mirror 222. The light engine accommodating groove 2233 is used to provide a mounting position for the light engine 21. The light output port 2234 is used to output the image light reflected by the curved mirror 222.

[0057] Specifically, referring to Figure 4 , Figure 4 is Figure 3 a structural schematic view of an angle of the housing 221. The housing body 223 includes a first side shell 2235, a second side shell 2236, a third side shell 2237, and a fourth side shell 2238. The first side shell 2235 and the second side shell 2236 are oppositely and spacedly arranged in the X direction. The third side shell 2237 and the fourth side shell 2238 are oppositely and spacedly arranged in the Y direction.

[0058] The first side shell 2235, the third side shell 2237, the second side shell 2236 and the fourth side shell 2238 are sequentially connected end to end. The enclosed space is the cavity 2231 of the shell body 223. The first side shell 2235, the third side shell 2237, the second side shell 2236 and the fourth side shell 2238 enclose the mounting opening 2232 on the side facing the Z direction. The first side shell 2235, the third side shell 2237, the second side shell 2236 and the fourth side shell 2238 enclose the light exit opening 2234 on the side facing the opposite direction of the Z direction.

[0059] The first side shell 2235 is provided with a light engine accommodating groove 2233. The light engine accommodating groove 2233 is recessed from the surface of the first side shell 2235 facing the second side shell 2236. The groove bottom wall of the light engine accommodating groove 2233 (the groove wall away from the second side shell 2236) is provided with a light transmission hole 2239. The light transmission hole 2239 penetrates the groove bottom wall of the light engine accommodating groove 2233 and the surface of the first side shell 2235 away from the second side shell 2236. The light transmission hole 2239 is used for the light rays of the light engine 21 to pass through and then be incident to the curved mirror 222.

[0060] The width (dimension along the Z direction) of the second side shell 2236 is smaller than the width (dimension along the Z direction) of the first side shell 2235.

[0061] The third side shell 2237 includes a first face 2340 and a second face 2341. The first face 2340 and the second face 2341 are oppositely arranged along the thickness direction (Y direction) of the third side shell 2237, and the first face 2340 is the surface of the third side shell 2237 facing the fourth side shell 2238. The second face 2341 is the surface of the third side shell 2237 away from the fourth side shell 2238.

[0062] The third side shell 2237 is provided with a first welding groove 2342. The first welding groove 2342 is recessed from the first face 2340. The first welding groove 2342 penetrates the surface of the third side shell 2237 facing the Z direction. The first welding groove 2342 is located at the edge of the mounting opening 2232.

[0063] Illustratively, the groove wall of the first welding groove 2342 is provided with a positioning column 2343. The positioning column 2343 is protruded from the groove wall of the first welding groove 2342 facing the Z direction. The positioning column 2343 is used to provide pre-positioning with the curved mirror 222 during installation.

[0064] Please refer to Figure 5 , Figure 5 is Figure 4Another perspective view of the housing 221 is shown. The fourth side housing 2238 includes a third face 2344 and a fourth face 2345. The third face 2344 and the fourth face 2345 are disposed opposite to each other along the thickness direction (Y direction) of the third side housing 2237. The third face 2344 is a surface of the fourth side housing 2238 facing the third side housing 2237. The fourth face 2345 is a surface of the fourth side housing 2238 facing away from the third side housing 2237.

[0065] The fourth side housing 2238 is provided with a second welding groove 2346. The second welding groove 2346 is recessed from the third face 2344. The second welding groove 2346 extends through the surface of the fourth side housing 2238 facing the Z direction. The second welding groove 2346 is located at the edge of the mounting opening 2232. The second welding groove 2346 is disposed opposite to the first welding groove 2342 in the Y direction.

[0066] The second welding groove 2346 is provided with a positioning column 2347. The positioning column 2347 is protruded from the groove wall of the second welding groove 2346 facing the Z direction. The positioning column 2347 is used to provide a predetermined position with the mirror 222 body during installation.

[0067] Please refer to Figure 4 and Figure 5 The number of the first welding portion 224 can be two. One first welding portion 224 can be connected to the groove wall of the first welding groove 2342 facing the Z direction. The other first welding portion 224 can be connected to the groove wall of the second welding groove 2346 facing the Z direction. The first welding portion 224 and the groove wall of the welding groove (the first welding groove 2342 and the second welding groove 2346) can be an integral structure. The first welding portion 224 can be a light-absorbing material. For example, polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), fluororesin (PFA), olefin resin (PE), engineering resin (PBT), super engineering resin (PSF), etc.

[0068] Thermoplastic materials can absorb laser energy and convert light energy into heat energy under the process of laser welding. The contact surface of the material is melted to form a molten zone. The molten zones of the two materials produce intermolecular mixing, and form a weld after cooling, thereby fastening the two materials into one body.

[0069] Exemplarily, the shell 221 can further include reinforcing ribs 235. The reinforcing ribs 235 can be arranged on the outer surface of the shell body 223. The reinforcing ribs 235 can be in a grid shape.

[0070] In the present embodiment, the arrangement of the reinforcing ribs 235 can significantly improve the deformation resistance of the shell 221. When the shell 221 is subjected to external forces, the reinforcing ribs 235 can effectively disperse and resist these external forces, thereby preventing the shell 221 from being excessively bent or deformed. The reinforcing ribs 235 can increase the load bearing capacity of the shell 221. When bearing a load, the reinforcing ribs 235 can share the bearing force and reduce the stress concentration phenomenon of the shell 221, thereby improving the overall strength of the shell 221.

[0071] Please refer to Figure 3 , the curved mirror 222 includes a curved mirror body 2221 and a second welding portion 2222. The curved mirror body 2221 and the second welding portion 2222 are integrally formed. The second welding portion 2222 is a portion of the curved mirror body 2221 that is melted and solidified during the welding process.

[0072] The curved mirror body 2221 can adjust the propagation path of the image light by its specific curved shape, ensuring that the light propagates in a predetermined direction. The curved mirror body 2221 can also magnify the image generated by the light machine 21, allowing the user to clearly see the required information at a greater distance.

[0073] The curved mirror body 2221 can be an optical element with a curved reflective surface. The curved surface can be a spherical surface, a non-spherical surface, or a free-form surface, etc. The non-spherical surface generally refers to a quadratic surface with an axis of revolution, such as a parabolic surface, an ellipsoidal surface, a involute surface, a hyperbolic surface, etc., as well as higher-order curved surfaces, and non-rotational non-spherical surfaces, such as off-axis non-spherical surfaces, etc. A free-form surface is an optical structure with a more complex surface shape, where the curvature radius of each point on the surface is different, and the degree of freedom of the surface shape is very high. The free-form surface has a complex surface shape and a high degree of freedom, and is generally considered to have no global rotational symmetry, no uniform optical axis, and multiple curvature radii on the entire surface.

[0074] The second welding portion 2222 is connected to the edge of the curved mirror body 2221. Please refer to Figure 6 , Figure 6 is Figure 3 another angle of the structure of the curved mirror 222. The second welding portion 2222 can also be provided with a positioning groove 2220. The positioning groove 2220 can be recessed from one surface of the second welding portion 2222 in the thickness direction.

[0075] The second welded part 2222 can be made of light-absorbing materials. For example, polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), fluoropolymer (PFA), olefin resin (PE), engineering resin (PBT), super engineering resin (PSF), and other plastic materials.

[0076] For example, please refer to the following: Figure 3 and Figure 4 There can be two second welding parts 2222. One second welding part 2222 is located within the first welding groove 2342. The positioning groove 2220 of the second welding part 2222 accommodates the positioning post 2347 of the first welding groove 2342, and is either in contact with or has a gap from the first welding part 224 located within the first welding groove 2342. The other second welding part 2222 is located within the second welding groove 2346. The positioning post 2347 of the second welding part 2222 accommodates the positioning post 2347 of the second welding groove 2346, and is either in contact with or has a gap from the first welding part 224 located within the second welding groove 2346. During the alignment process between the curved mirror 222 and the housing 221, tooling fixtures, robotic arm rotating parts, and other methods can be used to adjust the spatial position to ensure the relative positional accuracy between the curved mirror 222 and the housing 221.

[0077] The second welding part 2222 is connected to the first welding part 224 by a welding process, so that the curved mirror body 2221 covers the mounting opening 2232. The welding process can be contour welding, synchronous welding, scanning welding, mask welding, etc.

[0078] Contour welding refers to the process of using a laser light source to scan along the contour lines of the parts to be welded. The laser's thermal effect melts the plastic or thermoplastic material, thus achieving welding. This welding method is usually accomplished by moving a worktable or by relative movement of the laser beam to ensure that the laser can precisely weld along a predetermined path.

[0079] Simultaneous welding is based on laser beam guidance, which precisely concentrates energy into the area to be welded. Laser beams from multiple diode lasers are shaped by optical elements and guided along the contour line of the weld layer. These laser beams simultaneously generate heat at the weld joint, causing the entire contour line to melt and bond together at the same time.

[0080] The scanning welding technology realizes the arbitrary deflection of the laser beam by the laser beam being incident on two mirrors of a scanning galvanometer and the angles of the mirrors being controlled by a computer. In this way, the laser with a certain power density can be focused on different positions on the surface of the workpiece to realize the welding function.

[0081] The mask welding technology places a mask between the laser and the workpiece to be welded. The mask has a certain shielding effect on the laser beam. When the laser beam is transmitted to the welding area of the workpiece to be welded, the laser beam only transmits through the area of the mask that is not shielded by the laser to heat and weld the weld. The mask is designed according to the geometry of the weld.

[0082] In the present embodiment, the shell 221 and the curved mirror 222 are connected by welding. For example, at least part of the first welding portion 224 of the shell 221 and at least part of the second welding portion 2222 of the curved mirror 222 melt at high temperature in the process of laser welding, the melted first welding portion 224 and the melted second welding portion 2222 contact (directly or indirectly) and re-solidify into one body.

[0083] The laser welding technology has extremely high heating and cooling speed, which means that the first welding portion 224 and the second welding portion 2222 can quickly reach the required temperature for welding during the welding process and quickly cool down after the welding is completed. This rapid heating and cooling process greatly reduces the thermal stress generated by the curved mirror 222 during the welding process. The reduction of thermal stress helps to maintain the shape stability and structural integrity of the curved mirror 222, avoids the change of the face type of the curved mirror 222, and the face type of the curved mirror 222 refers to the shape of the lens surface. The stable face type of the curved mirror 222 can reduce the frequency of replacement due to breakage, thereby reducing the maintenance cost. The stable curved mirror 222 can ensure the clarity and accuracy of the projected information, provide users with more intuitive and easy-to-read information, and improve the ride experience.

[0084] In addition, laser welding is a non-contact processing method, which means that during the welding process, the laser beam directly acts on the welding area (the first welding portion 224 and the second welding portion 2222) without the need for direct contact with the curved mirror body 2221. This non-contact processing method reduces the vibration stress caused by mechanical contact. The reduction of vibration stress helps to prevent the curved mirror body 2221 from being deformed or damaged during the welding process and ensures the quality and strength of the curved mirror 222 and the shell 221.

[0085] In the first possible embodiment, please refer to Figure 7 , Figure 7 is Figure 1Part structure diagram of the first embodiment of the curved mirror assembly 22. The first welding part 224 and the second welding part 2222 can be welded by direct welding method. The welding method can be laser welding.

[0086] Specifically, the two second welding parts 2222 are connected to two edges of the curved mirror body 2221 arranged in opposite directions in the Y direction. The first welding part 224 and the second welding part 2222 located in the same first welding groove 2342 are arranged in opposite directions in the Y direction. The surface of the first welding part 224 facing the second welding part 2222 is the first connecting surface 2223. The surface of the second welding part 2222 facing the first welding part 224 is the second connecting surface 2224. The first connecting surface 2223 and the second connecting surface 2224 are arranged in opposite directions.

[0087] In the state that the first welding part 224 and the second welding part 2222 are not laser welded, the first connecting surface 2223 and the second connecting surface 2224 can be attached. Alternatively, there is a gap between the first connecting surface 2223 and the second connecting surface 2224.

[0088] In the state that the first welding part 224 and the second welding part 2222 are connected by laser welding, the first connecting surface 2223 and the second connecting surface 2224 can be in molten contact and solidified connection to connect the first welding part 224 and the second welding part 2222. For example, the first connecting surface 2223 and the second connecting surface 2224 can be curved. Specifically, the cross-sectional shape of the first connecting surface 2223 can be sawtooth-shaped, S-shaped, wave-shaped, etc. The cross-sectional shape of the second connecting surface 2224 can be adapted to the cross-sectional shape of the first connecting surface 2223.

[0089] For example, please continue to refer to Figure 7 The first connecting surface 2223 is concavely provided with a plurality of grooves 2225, which are arranged at intervals along the extension direction of the first welding part 224. The second connecting surface 2224 is convexly provided with a plurality of protrusions 2226, which are arranged at intervals along the extension direction of the second welding part 2222, and one protrusion 2226 is located in one groove 2225.

[0090] In this embodiment, when the first connecting surface 2223 and the second connecting surface 2224 are curved, the contact surface of the first connecting surface 2223 and the second connecting surface 2224 is larger, the first connecting surface 2223 and the second connecting surface 2224 are in molten contact, and the welding area connected after cooling and solidification is also larger. Larger welding area can provide more connection points, thereby increasing the strength and stability of the connection. The increase of the welding area can also disperse stress and reduce the connection failure of the curved mirror 222 and the shell 221 caused by concentrated stress.

[0091] In some other embodiments, the first connecting surface 2223 and the second connecting surface 2224 can also be linear.

[0092] In a second possible embodiment, referring to Figure 8 and Figure 9 , Figure 8 is Figure 1 a schematic diagram of a part of a second embodiment of the curved mirror assembly 22, wherein, for the convenience of illustration, Figure 8 the light-transmitting member 226 in FIG. 2B is processed in perspective to make the structure under the light-transmitting member 226 presentable. Figure 9 is Figure 8 a schematic diagram of a cross section of the curved mirror assembly 22 at A-A. Different from the welding method of the first embodiment, the second embodiment is provided with a light-transmitting member 226 at the connection between the first welding part 224 and the second welding part 2222.

[0093] Specifically, the number of the light-transmitting member 226 is two, one of which is located in the first welding groove 2342, and the other of which is located in the second welding groove 2346. For the convenience of illustration, the first welding part 224, the second welding part 2222 and the light-transmitting member 226 located in the first welding groove 2342 are mainly described below. The first welding part 224, the second welding part 2222 and the light-transmitting member 226 located in the second welding groove 2346 can refer to the description of the structure of the components in the first welding groove 2342. The present application does not repeat the description here.

[0094] The curved mirror assembly 22 further comprises a light-transmitting member 226. The first welding part 224 and the second welding part 2222 are adjacently arranged in the Y direction. The first welding part 224 and the second welding part 2222 have a gap therebetween. Alternatively, the first welding part 224 and the second welding part 2222 are adjacently arranged.

[0095] It should be noted that the structure and positional relationship of the first welding part 224 and the second welding part 2222 of the present embodiment can refer to the description of the first welding part 224 and the second welding part 2222 above. The present application does not repeat the description of the structure and positional relationship of the first welding part 224 and the second welding part 2222 here.

[0096] The light-transmitting member 226 covers at least part of the first welding part 224 and at least part of the second welding part 2222. The light-transmitting member 226 can cover the gap between the first welding part 224 and the second welding part 2222. The shape of the orthographic projection of the light-transmitting member 226 to the first welding part 224 and the second welding part 2222 can be square, circular or other irregular shape. The present application does not limit the shape of the light-transmitting member 226. The shape of the light-transmitting member 226 can be adaptively set according to the gap between the first welding part 224 and the second welding part 2222.

[0097] The material of the light-transmitting member 226 can be transparent plastic. In the process of aligning the gap between the light-transmitting member 226 and the first and second welding portions 224 and 222, a fixture, a mechanical arm, or a rotating part can be used to adjust the spatial position to ensure the relative position accuracy of the gap between the light-transmitting member 226 and the first and second welding portions 224 and 222.

[0098] Referring to Figure 10 , Figure 10 is Figure 9 a schematic view of a welding line 227 formed by welding the first and second welding portions 224 and 222. The light-transmitting member 226 is connected to the first and second welding portions 224 and 222 by welding. A laser beam can form the welding line 227 on the surface of the first and second welding portions 224 and 222. The welding line 227 is located on the side of the first and second welding portions 224 and 222 away from the cavity 2231. The welding line 227 can have a square, a prototype, parallel lines, intersecting lines, irregular curves, multiple lines, or other shapes.

[0099] In this embodiment, when the welding line 227 extends from the first welding portion 224 to the second welding portion 222, the molten part of the first welding portion 224 can contact the molten part of the second welding portion 222. The mixing of the molecules in the molten areas can cause the first and second welding portions 224 and 222 to be tightly connected and integrated when cooled and solidified.

[0100] In one possible implementation, referring to Figure 10 , the welding line 227 includes a plurality of convex portions 2271 and a plurality of concave portions 2272. Two adjacent convex portions 2271 are connected by a concave portion 2272. The plurality of convex portions 2271 are located in one of the first and second welding portions 224 and 222, and the plurality of concave portions 2272 are located in the other of the first and second welding portions 224 and 222.

[0101] For example, a mask can be used to shield part of the light-transmitting member 226, and the position to be welded is exposed to the mask. During welding, the laser can directly weld the position exposed to the mask, thereby improving the welding accuracy.

[0102] In the embodiment, the first welding portion 224 and the second welding portion 2222 are covered by the light-transmitting piece 226 during welding. The laser beam can pass through the light-transmitting piece 226 to the surface of the first welding portion 224 and the second welding portion 2222. Under the action of the laser beam, the first welding portion 224 and the second welding portion 2222 melt, and the welding line 227 formed by the melted first welding portion 224 and the second welding portion 2222 can be in contact with the light-transmitting piece 226 and connected to the light-transmitting piece 226 after cooling and solidification.

[0103] The embodiment of the present application adds an additional light-transmitting piece 226 to provide additional support and protection for the entire welding area, improving the stability and safety of the overall structure of the curved mirror assembly 22. The light-transmitting piece 226 can disperse the stress borne by the welding position, reducing the risk of damage to the welding position due to stress concentration. The light-transmitting piece 226 can effectively isolate air, moisture and other corrosive media, preventing the welding position from being corroded, thereby prolonging the service life of the curved mirror assembly 22. In some application scenarios, the welding position may be subject to wear and tear. The addition of the light-transmitting piece 226 can significantly reduce wear and tear, maintaining the integrity of the curved mirror assembly 22. Maintaining the shape stability and structural integrity of the curved mirror 222 avoids changes in the surface shape of the curved mirror 222, and the stable curved mirror 222 can ensure the clarity and accuracy of the projected information, providing users with more intuitive and easy-to-read information, and improving the ride experience.

[0104] In a third possible embodiment, please refer to Figure 11 , Figure 11 is Figure 1 a cross-sectional view of the third embodiment of the curved mirror assembly 22, which is different from the curved mirror assembly 22 of the second embodiment. In the embodiment, the light-transmitting piece 226 and the housing body 223 are a one-piece structure.

[0105] Specifically, the number of light-transmitting pieces 226 is two, one light-transmitting piece 226 is located in the first welding groove 2342, and the other light-transmitting piece 226 is located in the second welding groove 2346. For simplicity of explanation, the first welding portion 224, the second welding portion 2222 and the light-transmitting piece 226 located in the first welding groove 2342 are mainly described below. The first welding portion 224, the second welding portion 2222 and the light-transmitting piece 226 located in the second welding groove 2346 can be referred to the description of the structure of the components in the first welding groove 2342.

[0107] The second welding portion 2222 of the curved mirror 222 is located between the light-transmitting member 226 and the groove wall of the first welding groove 2342. The partial light-transmitting member 226 covers the partial second welding portion 2222 in the Z direction.

[0108] During the welding process, the welding laser can pass through the light-transmitting member 226 and act on the surface of the first welding portion 224 opposite to the second welding portion 2222. And / or, the welding laser can act on the surface of the second welding portion 2222 facing the light-transmitting member 226, so that the second welding portion 2222 is melted and contacted with the light-transmitting member 226, and solidified to fix the light-transmitting member 226 and the second welding portion 2222, so that the second welding portion 2222 is fixedly connected with the first welding portion 224 through the light-transmitting member 226.

[0109] In the embodiment, the light-transmitting member 226 can be integrally formed with the housing body 223 by integral injection molding or the like. The integral molding technology integrates the assembly process of the originally dispersed light-transmitting member 226 and the housing 221, thereby reducing the production steps.

[0110] In addition, the integral molding of the light-transmitting member 226 and the housing 221 can also increase the connection strength of the light-transmitting member 226 and the housing 221, so that the connection of the light-transmitting member 226 and the housing 221 is more stable, and the impact resistance of the light-transmitting member 226 is improved, thereby dispersing the influence of external force on the welding positions of the first welding portion 224 and the second welding portion 2222 to a greater extent, and improving the stability of the connection of the curved mirror 222 and the housing 221. The stable curved mirror 222 can ensure the clarity and accuracy of the projection information, provide more intuitive and easy-to-read information for the user, and improve the riding experience.

[0111] In a fourth possible embodiment, please refer to Figure 12 , Figure 12 is Figure 1 the cross-sectional view of the fourth embodiment of the curved mirror assembly 22, which is different from the third embodiment of the curved mirror assembly 22.

[0113] Specifically, the light-transmitting piece 226 can be connected to the second welding portion 2222. In the Y direction, the light-transmitting piece 226 is protrudingly arranged relative to the second welding portion 2222 to a side away from the curved mirror body 2221. The second welding portion 2222 can be mounted in the first welding groove 2342. The part of the light-transmitting piece 226 protruding relative to the second welding portion 2222 is in abutment with the first welding portion 224. Alternatively, the part of the light-transmitting piece 226 protruding relative to the second welding portion 2222 has a gap with the first welding portion 224. The front projection of the part of the light-transmitting piece 226 in the Z direction covers the part of the first welding portion 224.

[0114] During welding, the welding laser can pass through the light-transmitting piece 226 and act on the surface of the first welding portion 224 opposite the second welding portion 2222. And / or, the welding laser can act on the surface of the first welding portion 224 facing the light-transmitting piece 226, so that the first welding portion 224 melts and contacts the light-transmitting piece 226 and solidifies to fix the light-transmitting piece 226 and the first welding portion 224, so that the first welding portion is fixedly connected to the first welding portion 224 through the light-transmitting piece 226.
