Description

Technical Field

[0001] This application relates to the field of vehicle interior technology, and more particularly to a projection device and a vehicle. Background Technology

[0002] With the increasing diversification of modern automotive functions, ambient lighting has become an important feature for enhancing the overall vehicle experience. It not only creates a comfortable atmosphere tailored to the driving scenario, adding to the driving pleasure, but also provides necessary auxiliary lighting when the vehicle is parked in dark or poorly lit environments, assisting the driver and passengers in getting in and out of the vehicle more safely, effectively improving the vehicle's practicality and safety. At the same time, ambient lighting also gives the vehicle a more distinctive personalized character, satisfying consumers' pursuit of a high-quality automotive interior.

[0003] However, the mainstream automotive ambient lighting on the market today still primarily consists of light strips mounted on the dashboard. Installing these light strips requires specially reserved mounting slots along the width of the vehicle on the dashboard, or a dedicated area for adhesive attachment. This installation method leads to layout conflicts in vehicles with compact dashboard layouts; for example, in small cars or some new energy vehicles, the usable area of ​​the dashboard is already limited due to overall vehicle space planning. If space is reserved for the installation of light strips, it will compress the layout of other core functional components on the dashboard (such as air conditioning vents, storage compartments, control button modules, etc.), potentially reducing the usable size of these components and disrupting the original logical layout of the dashboard, ultimately affecting the user experience. Utility Model Content

[0004] This application provides a projection device and a vehicle, the purpose of which is to enable the projection of different styles of lights and personalized patterns onto the dashboard and surrounding areas by placing the projection device in the passenger blind spot in front of the display, thereby significantly improving the atmosphere; and to solve the problem that traditional light strip ambient lights squeeze the layout of core components such as air conditioning vents on the dashboard due to the need to reserve installation space.

[0005] To achieve the above objectives, this application adopts the following technical solution: This application provides a projection device disposed between a dashboard and a vehicle display; the projection device includes a projection lamp and a protective housing; the projection lamp is disposed on the dashboard and inside the protective housing; The protective shell is detachably connected to the dashboard via a plug-in structure, and the protective shell is detachably connected to the side of the vehicle display facing the front of the vehicle via a snap-fit ​​structure.

[0006] In the above embodiments, this application places the projection device in the space between the dashboard and the in-vehicle display, i.e., in the blind spot in front of the in-vehicle display, improving space utilization, avoiding the projection device being too obtrusive in the vehicle, and enhancing the overall quality of the vehicle. Furthermore, by connecting the protective shell to both the dashboard and the in-vehicle display, and using a dual detachable structure of plug-in and snap-fit ​​connections for multi-point fixation, this collaborative design significantly improves the overall stability of the device connection, effectively preventing friction noise caused by component shaking during vehicle operation, and significantly improving in-vehicle comfort. Simultaneously, the detachable connection method means that if the protective shell is damaged, the entire projection device does not need to be replaced; only the protective shell needs to be removed and replaced, greatly reducing subsequent maintenance costs and meeting the needs of efficient maintenance of vehicle components. In some embodiments, the protective shell includes a bottom frame, two support arms, a first frame and a second frame, wherein both the first frame and the second frame are arched structures; The two support arms are respectively disposed at both ends of the bottom frame. The two ends of the first frame are respectively connected to the ends of the two support arms away from the bottom frame, and the first frame arches toward the top of the vehicle. The two ends of the second frame are respectively connected to the middle of the bottom frame and the middle of the first frame, and the second frame arches toward the top of the vehicle.

[0007] In the above embodiments, this application clarifies that the protective shell is composed of a bottom frame, two support arms, and a first and a second frame. Each frame is connected at its end and in the middle to form an integrated support structure. This frame design not only provides a stable space for the projection lamp, but also enhances the structural strength of the protective shell itself through the coordinated cooperation of multiple components, laying the foundation for a reliable connection with the dashboard and vehicle display. In some embodiments, the plug-in structure includes a first fixing hole, a second fixing hole, a first plug rod, and a second plug rod; both the first fixing hole and the second fixing hole are disposed on the instrument panel; The first insertion rod is disposed on the bottom frame and matches the first fixing hole; the second insertion rod is disposed on the support arm and matches the second fixing hole.

[0008] In the above embodiments, this application clearly defines the plug-in structure as consisting of a fixing hole on the dashboard and a plug rod on the protective shell. By plugging the first plug rod of the bottom frame into the first fixing hole of the dashboard and the second plug rod of the support arm into the second fixing hole of the dashboard, multi-point positioning and fixing of the protective shell and the dashboard are achieved. This multi-point connection method enhances the stability of the installation, effectively resists the vibration and impact during vehicle operation, avoids abnormal noise caused by component shaking and friction, and ensures the quietness and comfort of the vehicle interior environment. On the other hand, the design of the plug-in structure also simplifies the assembly process and improves production efficiency. In some embodiments, the snap-fit ​​structure includes a second protrusion, a third protrusion, a first latch, and a second latch; Both the second protrusion and the third protrusion are disposed on the side of the vehicle display facing the front of the vehicle; second slots are disposed on the side of the vehicle display facing the front of the vehicle and on both sides of the second protrusion. The first buckle is disposed on the support arm and engages with the third protrusion; the second buckle is disposed on the first frame and engages with the second protrusion; a first insert plate is disposed on the first frame and on both sides of the second buckle, and the first insert plate is embedded in the second slot.

[0009] In the above embodiments, this application clarifies that the snap-fit ​​structure is snapped into the third and second protrusions of the vehicle display by the first buckle of the support arm and the second buckle of the first frame, respectively. Combined with the positioning design of the first insert plate being embedded in the second slot, a multi-dimensional snap-fit ​​fixing relationship is formed. This connection method ensures the tightness and stability of the connection between the protective shell and the vehicle display, which can effectively avoid relative shaking and friction noise during driving and improve the comfort inside the vehicle. At the same time, the design of the snap-fit ​​structure takes into account both the ease of assembly and the reliability of connection, meeting the needs of rapid installation of vehicle parts. In some embodiments, the projection device includes a reinforcing cover that is fastened to the second frame.

[0010] In the above embodiments, this application attaches a reinforcing cover to the second frame of the protective shell. Through the structural cooperation between the reinforcing cover and the arched frame, the second frame is structurally strengthened, which can effectively resist external collision impacts, prevent it from deforming or being damaged due to force, and extend the service life of the protective shell. At the same time, the reinforcing cover provides a carrier for appearance decoration. The visual effect of the projection device can be enriched by adding design elements, which can improve the aesthetic coordination between the device and the dashboard area while ensuring structural strength. In some embodiments, the bottom frame is provided with a first socket and a second socket, the first frame is provided with a third socket, and the second frame is provided with a fourth socket; The reinforcing cover is provided with a first insert block, a second insert plate, and several third insert rods. The first insert block is inserted into the fourth insert hole, the second insert plate is inserted into the second insert hole, and the several third insert rods are respectively inserted into the first insert hole and the third insert hole.

[0011] In the above embodiments, this application clarifies that the reinforcing cover, through the first insert block, the second insert plate, and multiple third insert rods, forms a multi-point insertion fit with the insert holes on each frame of the protective shell. This multi-directional connection structure ensures the firmness of the assembly between the reinforcing cover and the protective shell, effectively preventing the reinforcing cover from shaking and causing friction noise during vehicle operation, thus ensuring the comfort of the vehicle interior. At the same time, the insertion method makes the reinforcing cover easy to disassemble and assemble, which is convenient for later maintenance and replacement, and can always maintain the structural compatibility with the protective shell to ensure the reinforcement and protection effect. In some embodiments, the projection device further includes a cover assembly detachably connected to the projection lamp, the cover assembly being used to protect the light-emitting components of the projection lamp.

[0012] In the above embodiments, this application forms a detachable connection between the cover assembly and the projection lamp. The cover assembly protects the light-emitting components of the projection lamp, which can effectively reduce the damage to the light-emitting components caused by bumps and impacts, and ensure the long-term stable operation of the projection device. At the same time, the detachable design allows the cover assembly to be replaced separately when damaged, without disassembling the entire projection lamp, simplifying the maintenance process and reducing maintenance costs. In addition, the cover assembly can also optimize the appearance of the projection device and improve its overall coordination with the dashboard area. In some embodiments, the cover assembly includes a cover plate with a light-transmitting hole for allowing light generated by the light-emitting component to pass through; the cover plate has a first slot on the side facing the projection lamp. The projection lamp has a third locking block on the side facing the cover plate that matches the first locking slot, and the third locking block engages with the first locking slot.

[0013] In the above embodiments, the cover plate of this application is fixed to the third block of the projection lamp through the first slot. This detachable connection method allows the cover plate to be quickly disassembled and replaced when damaged, which is convenient for later maintenance. At the same time, the cover plate is provided with a light-transmitting hole to allow the light of the light-emitting component to pass through. While protecting the light-emitting component, it ensures that the light can pass through smoothly to complete the projection, thus achieving compatibility between the protection function and the projection function. This ensures the safety of the light-emitting component without affecting the projection effect of the ambient light. In some embodiments, a first protrusion is provided on the cover plate; The cover assembly includes a protective cover, which has a through hole that matches the light-transmitting hole, and a third buckle that matches the first protrusion. The third buckle engages with the first protrusion.

[0014] In the above embodiments, this application forms a double protection structure by the snap-fit ​​cooperation between the protective cover and the cover plate. The protective cover can provide additional protection for the cover plate and the internal light-emitting components, further enhancing the impact resistance and improving the protection level of the light-emitting components. At the same time, the through holes on the protective cover correspond to the light-transmitting holes on the cover plate, ensuring that the projected light can pass through normally. The detachable snap-fit ​​design facilitates maintenance and replacement. The appearance of the protective cover can also incorporate design elements, enhancing the aesthetics of the projection device and achieving a unity of protection and decoration. In addition, this application also provides a vehicle, including a vehicle body; The vehicle body is equipped with an instrument panel, which is equipped with an in-vehicle display and the aforementioned projection device; wherein the projection device is connected to the side of the in-vehicle display facing the front of the vehicle.

[0022] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0023] With the increasing diversification of modern automotive functions, ambient lighting has become an important feature for enhancing the overall vehicle experience. It not only creates a comfortable atmosphere tailored to the driving scenario, adding to the driving pleasure, but also provides necessary auxiliary lighting when the vehicle is parked in dark or poorly lit environments, assisting the driver and passengers in getting in and out of the vehicle more safely, effectively improving the vehicle's practicality and safety. At the same time, ambient lighting also gives the vehicle a more distinctive personalized character, satisfying consumers' pursuit of a high-quality automotive interior.

[0024] However, the current mainstream automotive ambient lights on the market are still mainly light strips assembled on the instrument panel. The assembly of such light strips requires specially reserving adaptive installation slots on the instrument panel along the vehicle width direction, or planning an exclusive area available for pasting and fixing. This assembly method leads to prominent layout contradictions in models with relatively compact instrument panel layouts; for example, for small vehicles or some new energy vehicles, limited by the overall vehicle space planning, the available area of the instrument panel is already limited; if installation space is reserved for the light strip, the layout of other core functional components on the instrument panel (such as air conditioning outlets, storage compartments, control key modules, etc.) will be squeezed. This may not only reduce the practical size of these functional components, but also disrupt the original reasonable layout rhythm of the instrument panel, and ultimately affect the user experience.

[0025] Based on this, the present application provides a projection device and a vehicle. By arranging the projection device 100 in the passenger blind area in front of the display, the purpose of projecting different styles of lights and personalized patterns onto the instrument panel 300 and its surrounding area can be achieved, which significantly improves the ambient effect; and it can also solve the problem that traditional strip-type ambient lights squeeze the layout of core components such as the air conditioning outlet on the instrument panel 300 due to the need to reserve installation space.

[0026] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0027] As shown in the accompanying Figures 1 to 12 drawing, in an exemplary embodiment of the present application, the projection device 100 is arranged between the instrument panel 300 and the vehicle-mounted display 200; specifically, the projection device 100 is arranged in a region of the vehicle-mounted display 200 facing the front of the vehicle, that is, arranged in the blind area of the vehicle-mounted display 200.

[0028] In some embodiments, the projection device 100 is powered by a battery inside the vehicle.

[0029] In some embodiments, the projection device 100 establishes a communication connection with the vehicle infotainment system of the vehicle, and this connection can realize instruction transmission and data interaction between the two. A user can send control instructions to the projection device 100 through the operation interface of the vehicle infotainment system (such as a touch screen, voice instructions or physical keys), specifically including controlling the turning on and off of the projection device 100, and switching the patterns projected by the projection device 100 (such as light and shadow of different themes, brand logos, etc.) according to the user's own needs. Through this linkage control design between the vehicle infotainment system and the projection device 100, intelligent interaction between the vehicle and the user can be achieved, the way of human-computer interaction inside the vehicle is further enriched, and at the same time, allows the user to customize the projection effect according to the use scenario or personal preference, which greatly improves the personalization of the vehicle functions.

[0030] In some embodiments, the projection device 100 includes a projection lamp 140, and the projection lamp 140 is arranged on the instrument panel 300.

[0031] In some embodiments, the projection lamp 140 includes a light-emitting component and a heat sink. The light-emitting component includes a light source (such as an LED or laser module), a pattern carrier (pattern sheet or chip), and an optical lens group. The pattern carrier carries the pattern or light and shadow data to be projected, and can be a turntable capable of carrying multiple sets of pattern or light and shadow data. The turntable can be rotated by a motor to switch the pattern or light and shadow data currently illuminated by the light source. The lens group is used to converge, focus, and calibrate the projection angle of the light. The heat sink dissipates the heat generated by the light source in a timely manner, preventing overheating from affecting the performance and lifespan of the light source. During operation, the light source is powered on and emits light. The pattern carrier switches to the desired pattern or light and shadow data. The light first illuminates the pattern carrier, picking up the pattern or light and shadow information on the carrier. Subsequently, the light carrying the pattern information enters the lens group, and after convergence, focusing, and angle adjustment, a precise projection beam is formed. Finally, the pattern or light and shadow is clearly projected onto target areas such as the dashboard 300, achieving atmosphere creation or information display to meet the dynamic projection needs in vehicle scenarios.

[0032] It should be noted that the specific structure of the aforementioned projection lamp 140 (including the composition and connection relationship of the light-emitting component and the heat dissipation component) and the operating principle of the projection of the light-emitting component are all prior art, and their technical details are known to those skilled in the art. Therefore, there is no need to elaborate on them in this application.

[0033] In some embodiments, such as Figure 8 As shown, the instrument panel 300 is provided with mounting holes 310.

[0034] In some embodiments, the projection lamp 140 is fixed to the dashboard 300 by a mounting bracket 141, which is located on the side of the dashboard 300 facing the bottom of the vehicle, and the projection lamp 140 extends out of the dashboard 300 through a mounting hole 310.

[0035] In some embodiments, the projection device 100 includes a protective housing 110, a projection lamp 140 disposed within the protective housing 110, and the protective housing 110 covers the mounting holes 310 of the instrument panel 300.

[0036] In some embodiments, the protective housing 110 is detachably connected to the instrument panel 300 via a plug-in structure, and the protective housing 110 is detachably connected to the side of the vehicle display 200 facing the front of the vehicle via a snap-fit ​​structure.

[0037] In the above embodiments, the projection device 100 is positioned in the space between the dashboard 300 and the vehicle display 200, i.e., in the blind spot in front of the vehicle display 200, improving space utilization and preventing the projection device 100 from appearing too obtrusive inside the vehicle, thus enhancing the overall quality of the vehicle. Furthermore, the protective shell 110 is connected to both the dashboard 300 and the vehicle display 200, achieving multi-point fixation through a dual detachable structure of plug-in and snap-fit ​​connections. This collaborative design significantly improves the overall stability of the device connection, effectively preventing friction noise caused by component movement during vehicle operation and significantly improving in-vehicle comfort. Simultaneously, the detachable connection method means that if the protective shell 110 is damaged, it is not necessary to replace the entire projection device 100; only the protective shell 110 needs to be removed and replaced, greatly reducing subsequent maintenance costs and meeting the needs for efficient maintenance of vehicle components.

[0038] In some embodiments, such as Figure 9 , 10 As shown, the protective shell 110 includes a bottom frame 111, two support arms 112, a first frame 113 and a second frame 114, both of which are arched structures.

[0039] In some embodiments, two support arms 112 are respectively disposed at both ends of the bottom frame 111, and the two support arms 112 and the bottom frame 111 form a U-shaped structure; the first frame 113 is an inverted U-shaped structure, and the two ends of the first frame 113 are respectively connected to the ends of the two support arms 112 away from the bottom frame 111, and the first frame 113 arches towards the top of the vehicle; the second frame 114 is an inverted U-shaped structure, and the two ends of the second frame 114 are respectively connected to the middle of the bottom frame 111 and the middle of the first frame 113, and the second frame 114 arches towards the top of the vehicle, and the vertical distance between the middle of the second frame 114 and the bottom of the vehicle is greater than the vertical distance between the middle of the first frame 113 and the bottom of the vehicle.

[0040] In some embodiments, the bottom frame 111, the support arm 112, the first frame 113, and the second frame 114 are integrally injection molded.

[0041] In some embodiments, the protective shell 110 is provided with a plurality of heat dissipation holes to assist in the heat dissipation of the projection lamp 140.

[0042] In the above embodiments, this application clarifies that the protective shell 110 is composed of a bottom frame 111, two support arms 112, and first and second frames 114. Each frame is connected at its end and middle to form an integrated support structure. This frame design not only provides a stable space for the projection lamp 140, but also enhances the structural strength of the protective shell 110 itself through the coordinated cooperation of multiple components, laying the foundation for a reliable connection with the instrument panel 300 and the vehicle display 200.

[0043] In some embodiments, such as Figure 8 As shown, the plug-in structure includes a first fixing hole 320 and a second fixing hole 330 disposed on the instrument panel 300.

[0044] In some embodiments, there are two first fixing holes 320, which are symmetrically arranged on both sides of the mounting hole 310 of the instrument panel 300, and are located on the side of the mounting hole 310 of the instrument panel 300 facing the front of the vehicle.

[0045] In some embodiments, there are two second fixing holes 330, which are symmetrically arranged on both sides of the mounting hole 310 of the instrument panel 300, and are located on the side of the mounting hole 310 of the instrument panel 300 facing the front of the vehicle.

[0046] In some embodiments, such as Figure 9 , 10 As shown, the plug-in structure also includes a first plug rod 111c disposed on the bottom frame 111 and matched with the first fixing hole 320, and a second plug rod 112a disposed on the support arm 112 and matched with the second fixing hole 330; the first plug rod 111c is plugged into the first fixing hole 320, and the second plug rod 112a is plugged into the second fixing hole 330.

[0047] In some embodiments, there are two first insert rods 111c, which are disposed on the side of the bottom frame 111 facing the bottom of the vehicle, and the two first insert rods 111c are respectively disposed on both sides of the bottom frame 111.

[0048] In some embodiments, there are two second insert rods 112a. The second insert rods 112a are located on the side of the support arm 112 facing the bottom of the vehicle, and on the side of the support arm 112 near the bottom frame 111.

[0049] In some embodiments, the first insertion rod 111c is provided with a rectangular hole, and a first locking block 111d is provided inside the rectangular hole. The first locking block 111d is connected to the upper edge of the rectangular hole through an elastic arm. When the first insertion rod 111c is inserted into the first fixing hole 320, the first locking block 111d is squeezed by the edge of the first fixing hole 320 and moves towards the center of the first fixing hole 320. The first insertion rod 111c continues to be inserted downwards, and after the first locking block 111d passes through the first fixing hole 320, it rebounds under the action of the elastic arm and is locked at the outer edge of the first fixing hole 320. Specifically, the side of the first locking block 111d near the top of the vehicle abuts against the side of the dashboard 300 facing the bottom of the vehicle.

[0050] In some embodiments, the first insertion rod 111c corresponds one-to-one with the first fixing hole 320, and the second insertion rod 112a corresponds one-to-one with the second fixing hole 330.

[0051] In some embodiments, the number of the first insertion rod 111c and the second insertion rod 112a may be 3, 4 or 5.

[0052] In the above embodiments, this application clearly defines the plug-in structure as consisting of a fixing hole on the instrument panel 300 and a plug rod on the protective shell 110. By plugging the first plug rod 111c of the bottom frame 111 with the first fixing hole 320 of the instrument panel 300 and the second plug rod 112a of the support arm 112 with the second fixing hole 330 of the instrument panel 300, the multi-point positioning and fixing of the protective shell 110 and the instrument panel 300 is realized. This multi-point connection method enhances the installation stability, effectively resists the vibration and impact during vehicle operation, avoids abnormal noise caused by component shaking and friction, and ensures the quietness and comfort of the vehicle interior environment. On the other hand, the design of the plug-in structure also simplifies the assembly process and improves production efficiency.

[0053] In some embodiments, such as Figure 5 As shown, the snap-fit ​​structure includes a second protrusion 210 and a third protrusion 230 disposed on the side of the vehicle display 200 facing the front of the vehicle, and a second slot 220 is disposed on both sides of the second protrusion 210 on the side of the vehicle display 200 facing the front of the vehicle.

[0054] In some embodiments, there is one second protrusion 210 and two third protrusions 230; the second protrusion 210 is disposed in the middle of the upper half of the vehicle display 200, and the two third protrusions 230 are respectively disposed on both sides of the lower half of the vehicle display 200; the line connecting the second protrusion 210 and the two third protrusions 230 forms a triangle.

[0055] In some embodiments, the vehicle display 200 has two protrusions on the side facing the front of the vehicle, the two protrusions are disposed on both sides of the lower half of the vehicle display 200, and a third protrusion 230 is disposed on the protrusions. The third protrusion 230 extends along the width direction of the vehicle, and the two third protrusions 230 are disposed opposite to each other.

[0056] In some embodiments, such as Figure 9As shown, the snap-fit ​​structure also includes a first snap-fit ​​112b disposed on the support arm 112 and a second snap-fit ​​113b disposed on the first frame 113; a first insert plate 113c is disposed on the first frame 113 and on both sides of the second snap-fit ​​113b. The first snap-fit ​​112b engages with the third protrusion 230; the second snap-fit ​​113b engages with the second protrusion 210; and the first insert plate 113c is embedded in the second slot 220. Specifically, when the first buckle 112b is pressed against the third protrusion 230, the two side walls of the groove on the first buckle 112b undergo elastic deformation outward. As the pressure continues, the third protrusion 230 passes through the narrowest part of the groove on the first buckle 112b, and the two side walls of the groove on the first buckle 112b spring back to lock the third protrusion 230 into the groove of the first buckle 112b. The engagement method between the second buckle 113b and the second protrusion 210 is the same as the engagement method between the first buckle 112b and the third protrusion 230, and will not be described again.

[0057] In some embodiments, the first buckle 112b is disposed on the side of the support arm 112 away from the bottom frame 111, and the first buckle 112b is disposed on the side of the support arm 112 facing the bottom of the vehicle.

[0063] In some embodiments, there are two first sockets 111a, which are respectively located on both sides of the bottom frame 111; and there is one second socket 111b, which is located in the middle of the bottom frame 111.

[0064] In some embodiments, there are two third sockets 113a, which are respectively located on both sides of the first frame 113.

[0065] In some embodiments, there are two fourth sockets 114a, both located in the middle of the second frame 114 and spaced apart along the width direction of the vehicle.

[0066] In some embodiments, such as Figure 11 As shown, the reinforcing cover 130 is provided with a first insert block 131, a second insert plate 134, and several third insert rods 132; the first insert block 131 corresponds one-to-one with the fourth insert hole 114a, and the first insert block 131 is inserted into the fourth insert hole 114a; the second insert plate 134 corresponds one-to-one with the second insert hole 111b, and the second insert plate 134 is inserted into the second insert hole 111b; there are four third insert rods 132 in total, in pairs, one pair corresponds one-to-one with the first insert hole 111a, and the other pair corresponds one-to-one with the third insert hole 113a, and several third insert rods 132 are respectively inserted into the first insert hole 111a and the third insert hole 113a.

[0067] In some embodiments, the second frame 114 is provided with a first through hole 114b, and a first pressing block 114c is provided in the first through hole 114b. The first pressing block 114c is connected to the upper edge of the first through hole 114b through an elastic arm.

[0068] In some embodiments, the reinforcing cover 130 is provided with a second locking block 133 that mates with the first pressing block 114c. When the reinforcing cover 130 is fastened onto the second frame 114, the second locking block 133 presses against the first pressing block 114c, the first pressing block 114c moves away from the second locking block 133, the reinforcing cover 130 continues to press down, the second locking block 133 and the first pressing block 114c are misaligned, and the first pressing block 114c rebounds; at this time, the side of the first pressing block 114c near the bottom of the vehicle abuts against the side of the second locking block 133 near the top of the vehicle.

[0069] In some embodiments, there are four first through holes 114b and four first pressing blocks 114c. The first through holes 114b are arranged in pairs, with one pair located on the side of the second frame 114 near the bottom frame 111 and the other pair located on the side of the second frame 114 near the first frame 113. There are also four second locking blocks 133, which correspond one-to-one with the first pressing blocks 114c.

[0070] In some embodiments, the reinforcing cover 130 is provided with a plurality of heat dissipation holes to assist in the heat dissipation of the projection lamp 140.

[0071] In the above embodiments, this application clarifies that the reinforcing cover 130, through the first insert block 131, the second insert plate 134, and multiple third insert rods 132, forms a multi-point insertion fit with the insertion holes on each frame of the protective shell 110. This multi-directional connection structure ensures the firmness of the assembly between the reinforcing cover 130 and the protective shell 110, effectively preventing the reinforcing cover 130 from shaking and causing friction noise during vehicle operation, thus ensuring the comfort of the vehicle interior. At the same time, the insertion method makes the reinforcing cover 130 easy to disassemble and assemble, which is convenient for later maintenance and replacement, and can always maintain the structural compatibility with the protective shell 110, ensuring the enhanced protection effect.

[0072] In some embodiments, the projection device 100 further includes a cover assembly 120, which is detachably connected to the projection lamp 140 and is used to protect the light-emitting components of the projection lamp 140.

[0073] In the above embodiments, the present application forms a detachable connection between the cover assembly 120 and the projection lamp 140. The cover assembly 120 protects the light-emitting component of the projection lamp 140, which can effectively reduce the damage to the light-emitting component caused by bumps and impacts, and ensure the long-term stable operation of the projection device 100. At the same time, the detachable design allows the cover assembly 120 to be replaced separately when damaged, without disassembling the entire projection lamp 140, simplifying the maintenance process and reducing maintenance costs. In addition, the setting of the cover assembly 120 can also optimize the appearance of the projection device 100 and improve the overall coordination with the dashboard 300 area. In some embodiments, such as Figure 4 , 12As shown, the cover plate assembly 120 includes a cover plate 121, on which a light-transmitting hole 121a is provided, which is used to allow light generated by the light-emitting component to pass through; a first slot 121b is provided on the side of the cover plate 121 facing the projection lamp 140.

[0074] In some embodiments, the projection lamp 140 is provided with a third locking block 142 on the side facing the cover plate 121, which matches the first locking slot 121b. The third locking block 142 is engaged with the first locking slot 121b.

[0075] In some embodiments, the opening of the first slot 121b faces the bottom of the vehicle, and the third block 142 is embedded in the first slot 121b to connect the cover plate 121 with the projection lamp 140.

[0076] In some embodiments, there are four first card slots 121b, arranged in pairs on both sides of the cover plate 121. There are also four third card blocks 142, each corresponding to one of the first card slots 121b.

[0077] In the above embodiments, the cover plate 121 of this application is fixedly connected to the third locking block 142 of the projection lamp 140 through the first locking slot 121b. This detachable connection method allows the cover plate 121 to be quickly disassembled and replaced when damaged, which is convenient for later maintenance. At the same time, the cover plate 121 is provided with a light-transmitting hole 121a to allow the light of the light-emitting component to pass through. While protecting the light-emitting component, it ensures that the light can pass through smoothly to complete the projection, thus achieving compatibility between the protection function and the projection function. This ensures the safety of the light-emitting component without affecting the projection effect of the ambient light. In some embodiments, such as Figure 12 As shown, a first protrusion 121c is provided on the cover plate 121.

[0078] In some embodiments, the cover assembly 120 includes a protective cover 122, which has a through hole that matches the light-transmitting hole 121a. The protective cover 122 also has a third latch 122a that matches the first protrusion 121c. The third latch 122a engages with the first protrusion 121c. Specifically, when the first protrusion 121c engages with the third latch 122a, the first protrusion 121c presses against the two sidewalls of the groove of the third latch 122a, causing the sidewalls of the groove of the third latch 122a to expand outwards. When the first protrusion 121c passes through the narrowest part of the groove of the third latch 122a, the sidewalls of the groove of the third latch 122a spring back and engage with the first protrusion 121c.

[0079] In some embodiments, there are four first protrusions 121c, arranged in pairs on both sides of the cover plate 121. There are also four third latches 122a, each corresponding to one of the first protrusions 121c.

[0080] In the above embodiments, this application forms a double protection structure by engaging the protective cover 122 with the cover plate 121. The protective cover 122 can provide additional protection for the cover plate 121 and the internal light-emitting components, further enhancing the impact resistance and improving the protection level of the light-emitting components. At the same time, the through holes on the protective cover 122 correspond to the light-transmitting holes 121a of the cover plate 121, ensuring that the projected light can pass through normally. The detachable snap-fit ​​design facilitates maintenance and replacement. The appearance of the protective cover 122 can also incorporate design elements, enhancing the aesthetics of the projection device 100 and achieving a unity of protection and decoration. In addition, this application also provides a vehicle, including a vehicle body; The vehicle body is equipped with an instrument panel 300, on which an in-vehicle display 200 and the aforementioned projection device 100 are mounted; wherein, the projection device 100 is connected to the side of the in-vehicle display 200 facing the front of the vehicle. Through the projection device, the vehicle can project different themed lighting onto the instrument panel 300, enabling intelligent interaction, increasing human-computer interaction methods, and adding personalized settings.
