[0048] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0049] Current projection devices include a camera module, a projector body, and a housing. The camera module is typically mounted directly on the housing, while the projector body usually needs to be fixed inside the housing using a bracket.

[0050] However, the relative positions of the camera module and the projector body are highly susceptible to change after disassembly and repair. For example, during disassembly and repair, the projector body and stand need to be removed from the casing together. After repair, the stand with the projector body installed needs to be re-secured inside the casing. During this process, the camera module is usually fixed to the casing. Therefore, after the projector body is moved back inside the casing, it is difficult to guarantee that its position inside the casing is the same as before disassembly and repair. Consequently, the relative positions of the projector body and the camera module are highly prone to change after the projector body is moved back inside the casing.

[0051] When the relative position between the projector and the camera module changes, the projection device can no longer accurately correct the image projected by the projector based on the camera module, resulting in a poor display effect.

[0052] Typically, the relative positions between the camera module and the projector body need to be recalibrated to improve the accuracy of the projection device's image correction. However, the process of recalibrating the relative positions between the camera module and the projector body is quite complex, making the projection device more difficult to use.

[0053] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a projection device provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the internal structure of the projection device. The projection device 000 may include: a housing 100, a main support 200, a camera module 300, and a projector body 400.

[0054] To more clearly show the structure of the housing 100 in the projection device 000, the housing 100 in the projection device 000 may have: a receiving cavity (not marked in the figure), and a light-transmitting hole V1 and a light-emitting opening V2 communicating with the receiving cavity.

[0055] The main support 200 in the projection device 000 can be located within the receiving cavity and connected to the outer casing 100. For a clearer view of the structure of the main support 200, please refer to [reference needed]. Figure 3 , Figure 3 This is a schematic diagram of the structure of a main support provided in an embodiment of this application. The main support 200 in the projection device 000 may have: a first mounting position Q1 and a second mounting position Q2.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, the camera module 300 in the projection device 000 can be fixedly connected to the first mounting position Q1 of the main bracket 200, and the photosensitive surface of the camera module 300 can face the light-transmitting hole V1 of the housing 100. Here, the camera module 300 can obtain ambient light through the light-transmitting hole V1 to form an image.

[0057] The projector body 400 in the projection device 000 can be fixedly connected to the second mounting position Q2 of the main bracket 200, and the light-emitting side of the projector body 400 faces the light-emitting opening V2 of the housing 100. Here, the projector body 400 can project a projected image outward through the light-emitting opening V2.

[0058] In this application, the projection device 000 can correct the image projected by the projector body 400 based on the camera module 300. In one possible implementation, the camera module 300 may include an optical camera 310 and a depth camera 320. The depth camera 320 is a TOF (Time of Flight) camera. Here, the optical camera 310 is used to acquire an image containing the projected image projected by the projector body 400, and the depth camera 320 is used to acquire the depth data of each pixel in the acquired image. In this way, the projection device 000 can correct the projected image projected by the projector body 400 based on the image acquired by the optical camera 310 and the depth data of each pixel in the image acquired by the depth camera 320, so that the display effect of the projected image is better.

[0059] In this embodiment, the camera module 300 can be mounted and fixed on the first mounting position Q1 of the main bracket 200, and the projector body 400 can be mounted and fixed on the second mounting position Q2 of the main bracket 200. Therefore, the camera module 300 and the projector body 400 are mounted on the same main bracket 200, and the relative positions between the first mounting position Q1 and the second mounting position Q2 on the main bracket 200 are fixed. This ensures that the relative positions between the camera module 300 and the projector body 400 are also fixed. Thus, even if the projector 000 is disassembled for repair, after reassembling the projector 000, the relative positions between the camera module 300 and the projector body 400 remain fixed. This ensures that the projector 000 effectively corrects the image projected by the projector body 400 based on the camera module 300, resulting in a better display effect. Furthermore, even if the projection device 000 is disassembled and repaired, the relative positions between the camera module 300 and the projector body 400 remain fixed. Therefore, there is no need to recalibrate the relative positions between the camera module 300 and the projector body 400, which simplifies the use of the projection device.

[0060] In summary, the projection device provided in this application includes: a housing, a main bracket, a camera module, and a projector body. Since the camera module can be mounted and fixed on a first mounting position on the main bracket, and the projector body can be mounted and fixed on a second mounting position on the main bracket, the camera module and the projector body are mounted on the same main bracket, and the relative positions between the first and second mounting positions on the main bracket are fixed. This ensures that the relative positions between the camera module and the projector body are also fixed. Thus, even if the projection device is disassembled for repair, the relative positions between the camera module and the projector body remain fixed after reassembly. This ensures that the projection device effectively corrects the image projected by the projector body based on the camera module, resulting in better image display. Furthermore, even if the projection device is disassembled for repair, there is no need to recalibrate the relative positions between the camera module and the projector body, simplifying the use of the projection device.

[0061] Please refer to Figure 4 , Figure 4 This is a schematic diagram illustrating the assembly of a camera module and a main bracket according to an embodiment of this application. The camera module 300 may include a circuit board 300a and a main camera device 300b fixed on the circuit board. Here, the circuit board 300a may be fixedly connected to the main bracket 200 at a first mounting position Q1, and the main camera device 300b may be located on the side of the circuit board away from the first mounting position Q1.

[0062] Here, the light-sensing direction of the main camera device 300b can be towards the light-transmitting hole V1 of the housing 100, and the main camera device 300b can obtain ambient light through the light-transmitting hole V1. The circuit board 300a can process the main camera device 300b into corresponding electrical signals and transmit them to the motherboard of the projection device 000.

[0063] In one possible implementation, the camera module 300 includes two circuit boards 300a and two main camera devices 300b respectively fixed on the two circuit boards 300a. Here, the main bracket 200 has two first mounting positions Q1, and the two circuit boards 300a can be fixed on the two first mounting positions Q1 respectively.

[0064] For example, such as Figure 5 As shown, Figure 5 yes Figure 4 The diagram shows a partial enlarged view of the structure at point A. The two first mounting positions Q1 of the main bracket 200 are: a first sub-position Q11 and a second sub-position Q12. The circuit board fixedly connected to the main bracket 200 at the first sub-position Q11 is a first circuit board 330, and the main camera device on the first circuit board 330 is an optical camera 310. The circuit board fixedly connected to the main bracket 200 at the second sub-position Q12 is a second circuit board 340, and the main camera device on the second circuit board 340 is a depth camera 320.

[0065] In this application, the way in which the first circuit board 330 is fixedly connected to the main bracket 200 at the first sub-position Q11 and the way in which the second circuit board 340 is fixedly connected to the main bracket 200 at the second sub-position Q12 are substantially similar. Therefore, the following embodiment will be described using the example of a single circuit board 300a being mounted on a first mounting position Q1.

[0066] Please refer to Figure 6 , Figure 6 This is a partially enlarged view of a main support at a first mounting position according to an embodiment of this application. The first mounting position Q1 of the main support 200 has a mounting groove U that mates with a circuit board 300a, and at least two main support columns 210 located within the mounting groove U. At least a portion of the circuit board 300a may be located within this mounting groove U and contact the end face of the support column 110 opposite to the main support 200. The projection device 000 may further include at least two connectors (not shown in the figure) connected to at least two main support columns 210, each connector being used to lock the circuit board 300a onto the corresponding main support column 210.

[0067] For example, such as Figure 7 As shown, Figure 7This is a schematic diagram of a camera module according to an embodiment of this application. The circuit board 300a in the camera module 300 may have at least two connection holes P1, which correspond to at least two main support pillars 210. Each support pillar 110 may have a threaded hole P2 communicating with the corresponding connection hole P1. The connector may be a screw that mates with the threaded hole P2, so that the screw can pass through the connection hole P1 and be threadedly connected to the threaded hole P2. After the screw is threadedly connected to the threaded hole P2, the locking force applied to the circuit board 300a by the nut on the screw can securely lock the circuit board 300a onto the main support pillar 100.

[0068] In one possible implementation, at least two main support columns 210 are distributed on opposite sides of the mounting groove U in the first direction X. In this way, after being connected to at least two main support columns 210 by at least two connectors, the circuit board 300a can be locked more stably in the mounting groove U.

[0069] Optional, such as Figure 6 As shown, the sidewall of the mounting groove U may have at least one first limiting member 220. For example... Figure 7 As shown, the edge of the circuit board 300a may have at least one first limiting notch Z1. Here, at least one first limiting member 220 may correspond one-to-one with at least one first limiting notch Z1. At least a portion of each first limiting member 220 is located within the corresponding first limiting notch Z1.

[0070] For example, after the circuit board 300a is installed in the mounting groove U, the first limiting member 220 in the bearing groove U can limit the position of the circuit board 300a at the position of the corresponding first limiting notch Z1, so as to ensure that the circuit board 300a can not only be machined and supported on the main support column 210, but also that the connecting hole P1 of the circuit board 300a can be connected to the threaded hole P2 of the main support column 210.

[0071] In one possible implementation, there is one first limiting member 220, which can be located on one side of the mounting groove U in the first direction X. In this way, the position of the circuit board 300a can be restricted in the first direction X by the first limiting member 220 to ensure that the position of the first circuit board 120 in the first direction X will not be offset.

[0072] Of course, this first limiting member 220 can also be located on one side of the mounting groove U in the second direction Y. In this way, the first limiting member 220 can restrict the position of the circuit board 300a in the second direction Y to ensure that the position of the second circuit board 120 in the second direction Y will not be offset. Here, the first direction X can intersect with the second direction Y, for example, the first direction X can be perpendicular to the second direction Y.

[0073] In another possible implementation, such as Figure 8 As shown, Figure 8 This is a partial enlarged view of another main bracket provided in this application embodiment at the first mounting position. There are two first limiting members 220. One of these first limiting members 220 can be located on one side of the mounting groove U in the first direction X, thus limiting the position of the circuit board 300a in the first direction X to ensure that the position of the first circuit board 120 in the first direction X does not shift. The other of these two first limiting members 220 can be located on one side of the mounting groove U in the second direction Y, thus limiting the position of the circuit board 300a in the second direction Y to ensure that the position of the first circuit board 120 in the second direction Y does not shift.

[0074] In this application, as Figure 6 and Figure 8 As shown, the sidewall of the mounting slot U may also have at least one auxiliary support column 230. Here, the end face of the auxiliary support column 230 facing away from the main bracket 200 can contact the circuit board 300a. In this way, the auxiliary support column 230 can provide additional support for the circuit board 300a, so that the circuit board 300a can be placed more stably in the mounting slot U.

[0075] In one possible implementation, the auxiliary support column 230 and the first limiting member 220 can be connected at the same location as the mounting slot U.

[0076] Here, after the auxiliary support column 230 and the first limiting member 220 are connected at the same position where the mounting slot U can be installed, the strength of the first limiting member 220 can be increased by the auxiliary support column 230. Since the auxiliary support column 230 can provide additional support force to the circuit board 300a, the first limiting member 220 is more effective in limiting the position of the circuit board 300a that is subjected to additional support force.

[0077] Optional, such as Figure 6 As shown, the sidewall of the mounting groove U also has at least one first rib 240 and at least one second rib 250, and / or, the sidewall of the mounting groove U also has at least one third rib 260 and at least one fourth rib 270.

[0078] In the case where the sidewall of the mounting groove U also has at least one first rib 240 and at least one second rib 250, the at least one first rib 240 and at least one second rib 250 are located on opposite sides of the mounting groove U in the first direction X, and at least a portion of the circuit board 300a is located between the at least one first rib 240 and the at least one second rib 250 in the first direction X.

[0079] Here, after the circuit board 300a is placed in the mounting slot U, one side of the circuit board 300a in the first direction X can contact at least one first protrusion 240, and the other side of the circuit board 300a in the first direction X can contact at least one second protrusion 250. Through the cooperation of the first protrusion 240 and the second protrusion 250, the circuit board 300a can be further limited in the first direction X.

[0080] In the case where the sidewall of the mounting groove U also has at least one third rib 260 and at least one fourth rib 270, the at least one third rib 260 and at least one fourth rib 270 are located on opposite sides of the mounting groove U in the second direction Y, and at least a portion of the circuit board 300a is located between the at least one third rib 260 and the at least one fourth rib 270 in the second direction Y.

[0081] Here, after the circuit board 300a is placed in the mounting groove U, one side of the circuit board 300a in the second direction Y can contact at least one third protrusion 260, and the other side of the circuit board 300a in the second direction Y can contact at least one fourth protrusion 270. Through the cooperation of the third protrusion 260 and the fourth protrusion 270, the circuit board 300a can be further limited in the second direction Y.

[0082] In the embodiments of this application, such as Figure 9 As shown, Figure 9 This is a schematic diagram of the internal structure of another projection device provided in an embodiment of this application. The projection device 000 may further include: a motherboard 500, a first circuit section (not shown in the figure), and a second circuit section (not shown in the figure). Here, the motherboard 600 may be fixedly connected to the main bracket 200.

[0083] The two ends of the first line section are electrically connected to the motherboard 600 and the first circuit board 330, respectively. In this way, after the first circuit board 330 acquires image information through the optical camera 310, it can transmit the image information to the motherboard 600 through the first line section, so that the motherboard 600 can also obtain the image information acquired by the optical camera 330.

[0084] For example, the motherboard 600 is provided with a first connector, and one end of the first circuit section is provided with a second connector that plugs into the first connector; the first circuit board 330 is provided with a third connector, and the other end of the first circuit section is provided with a fourth connector that plugs into the third connector. Here, the types of the first and second connectors that are plugged in, as well as the types of the third and fourth connectors that are plugged in, can be the same or different. As long as a stable connection between the two can be achieved, this embodiment of the application does not limit this.

[0085] The two ends of the second circuit section are electrically connected to the main board 600 and the second circuit board 340, respectively. Thus, after the second circuit board 340 acquires depth information through the depth camera 320, it can transmit this information to the main board 600 via the second circuit section, allowing the main board 600 to also acquire the depth information acquired by the depth camera 320. Therefore, when the image projected by the projector 400 needs correction, the main board 600 can correct the image projected by the projector 400 based on the image information acquired by the optical camera 330 and the depth information acquired by the depth camera 320, ensuring a better displayed image after correction.

[0086] In one possible implementation, such as Figure 6 and Figure 8 As shown, the main bracket 200 has an abutment portion 280 at the second sub-position U12. This abutment portion 280 is used to abut against the part where the second circuit section and the second circuit board 340 are connected. In this way, after the abutment portion 280 abuts against the part where the second circuit section and the second circuit board 340 are connected, a stable electrical connection can be ensured between the second circuit section and the second circuit board 340, so as to ensure stable signal transmission between the second circuit board 340 and the main board 600.

[0087] It should be noted that the motherboard 600 also has a fifth connector, and one end of the second circuit section has a sixth connector that plugs into the fifth connector; the second circuit board 340 has a seventh connector, and the other end of the second circuit section has an eighth connector that plugs into the seventh connector. Here, the fifth and sixth connectors can usually be connected stably, but the connection between the seventh and eighth connectors is less secure. Therefore, the abutment part 280 is used to abut the seventh and eighth connectors to ensure that they do not loosen.

[0088] For example, the seventh and eighth connectors can be located on the side of the second circuit board 340 facing away from the depth camera. Here, after the second circuit board 340 is fixed at the second sub-position U12 and the seventh and eighth connectors are plugged in, the plugged seventh and eighth connectors are located between the second circuit board 340 and the abutment portion 280, and the connector used to assemble the second circuit board 340 can provide a locking force to the second circuit board 340. This locking force can be converted into a pressing force applied to the abutment portion 280. In this way, a force can be applied to the seventh and eighth connectors plugged in between the second circuit board 340 and the abutment portion 280 to ensure that the seventh and eighth connectors do not loosen.

[0089] Optional, such as Figure 8 As shown, the projection device 000 may further include a protective unit 600. Here, the protective unit 600 may be fixed in the circuit board 300a at the location where the main camera device 300b is installed, for sealing and protecting the main camera device 300b. For example, as... Figure 5 As shown, the protection part 600 provided on the first circuit board 330 can protect the optical camera 310, and the protection part 600 provided on the second circuit board 340 is used to protect the depth camera 320.

[0090] Here, after the main bracket 200, which houses the camera module 300, projector body 400, and protective part 600, is assembled into the receiving cavity of the housing 100, the protective part 600 can abut against the housing at the position of the light-transmitting hole V1. Furthermore, the protective part 600 has a certain degree of deformation capability. Thus, through the buffering protection of the protective part 600, even if the projection device 000 is subjected to external impact, the camera main component 300b can be protected. In addition, the protective part 600 also provides sealing for the projection device 000, preventing moisture or dust from the external environment from easily intruding into the interior of the projection device 000 through the light-transmitting hole V1.

[0091] In the embodiments of this application, please refer to Figure 10 , Figure 10 This is a schematic diagram of the structure of a housing provided in an embodiment of this application. A lens groove B is located at the position of the light-transmitting hole V1 on the outer surface of the housing 100. The projection device 000 may further include a protective lens 700 fixedly connected to the housing 100 within the lens groove B. Here, the protective lens 700 can be bonded to the lens groove B through a sealing adhesive layer, thereby sealing the light-transmitting hole V1 and further reducing the probability of moisture or dust from the external environment entering the interior of the projection device 000 through the light-transmitting hole V1.

[0092] Optional, please refer to Figure 11 , Figure 11This is a schematic diagram of the cooperation between a projector body and a main support according to an embodiment of this application. The second mounting position U2 of the main support 200 has a bearing space, and the projector body 100 can be assembled into this bearing space.

[0093] For example, the main support 200 may include: a connecting plate 201, and a first plate 202 and a second plate 203 fixedly connected to both sides of the connecting plate 201 in a first direction X. The connecting plate 201, the first plate 202, and the second plate 203 can be used to enclose a support space. The projector body 400 in the projection device 000 can be connected to the connecting plate 201 in this support space. Here, the projector body 400 can be attached to the connecting plate 201 by screws.

[0094] In one possible implementation, the projector body 400 may include a light source device 410, an optical engine device 420, and a projection lens 430. Here, the light source device 410 is used to provide an illumination beam, the optical engine device 420 is used to generate an image beam based on the illumination beam provided by the light source device, and guide the image beam to the projection lens 430. The projection lens 430 is used to image the image beam after receiving it and project it onto a projection screen to display an image on the projection screen.

[0095] The light source device 410, the optical engine device 420, and the projection lens 430 all include housings. The housing of the light source device 410 can be connected to the housing of the optical engine device 420, and the housing of the optical engine device 420 can also be connected to the housing of the projection lens 430. In this way, by connecting the housings of the light source device 410, the optical engine device 420, and the projection lens 430, the light source device 410, the optical engine device 420, and the projection lens 430 can be assembled into the projector body 400.

[0096] The connecting plate 201 in the main bracket 200 may be provided with multiple first connecting parts, and the housing of the light source device 410 in the projector body 400 may have multiple locking holes corresponding to the multiple first connecting parts. Multiple screws may be distributed and passed through the multiple locking holes and threadedly connected to the multiple first connecting parts respectively. In this way, the housing of the light source device 410 can be locked onto the connecting plate 201 by multiple screws, and then the projector body 400 can be assembled into the bearing space provided at the second mounting position U2 of the main bracket 200.

[0097] In the embodiments of this application, such as Figure 12 and Figure 13 As shown, Figure 12 This is a schematic diagram of another shell structure provided in an embodiment of this application. Figure 13This is a schematic diagram of another housing provided in an embodiment of this application. The projection device 000 may also include: an adapter frame 800 and a decorative component 900.

[0098] The adapter frame 800 can be connected to the housing 100 inside the receiving cavity, and the adapter frame 800 can be distributed at the location of the light-emitting opening V2 of the housing 100. The adapter frame 800 can also be fixedly connected to the main support 200. The decorative piece 900 can be connected to the adapter frame 800 outside the receiving cavity.

[0099] For example, during the assembly of the projection device 000, the adapter frame 800 can be assembled inside the housing 100 first. Then, the main support 200, which houses the camera module 300 and the projector body 400, is assembled inside the housing 100. Afterward, the adapter frame 800 and the main support 200 can be connected externally to the housing 100 using screws to ensure a secure connection. Finally, a decorative piece 900 can be assembled onto the adapter frame 800 externally. Here, the decorative piece 900 decorates the light-emitting opening V2 of the housing 100, thereby ensuring a better overall appearance of the projection device 000.

[0100] In one possible implementation, such as Figure 13 As shown, the inner sidewall of the housing 100 has a plurality of second connecting portions 110, which can be distributed around the periphery of the light-emitting opening V2. The adapter frame 800 can have a plurality of first openings V3 corresponding to the plurality of second connecting portions 110, and each second connecting portion 110 has a screw hole for communicating with the corresponding first opening V3. During the assembly of the housing 100 and the adapter frame 800, the decorative piece 800 can be placed inside the housing 110 at the position where the plurality of second connecting portions 110 are located, and each first opening V3 on the decorative piece 800 is made to communicate with the threaded hole on the corresponding second connecting portion 110. Then, a plurality of screws are used to sequentially pass through the plurality of first openings V3 and thread them into the plurality of threaded holes on the plurality of second connecting portions 110, thereby locking the adapter frame 800 inside the housing 100.

[0101] In this application, as Figure 14 As shown, Figure 14This is a schematic diagram illustrating the cooperation between an adapter frame and a decorative component provided in an embodiment of this application. The adapter frame 800 may also have at least one second opening V4. The main support 200 may also have a threaded hole for connecting with the second opening V4. During the assembly of the main support 200, the main support 200, on which the camera module 300 and the projector body 400 are mounted, can be assembled inside the housing 100, so that the threaded hole on the main support 200 communicates with the second opening V4. Then, a screw is passed through the second opening V4 and connected to the threaded hole on the main support 200. Thus, the adapter frame 800 can secure the main support 200 to the housing 100, ensuring that the main support 200 located inside the housing 100 does not easily shake inside the housing 100, thereby improving the image correction effect through the camera module 300.

[0102] Optional, such as Figure 14 and Figure 15 As shown, Figure 15 This is a schematic diagram illustrating the cooperation between another adapter frame and decorative element provided in this application embodiment. The adapter frame 800 may also have multiple first snap-fit ​​members 810, and the decorative element 900 may have multiple second snap-fit ​​members 910. Here, the multiple first snap-fit ​​members 810 and the multiple second snap-fit ​​members 910 can be snapped together one-to-one, so that the decorative element 900 can be snapped onto the adapter frame 800 outside the housing 100.

[0103] In one possible implementation, one of the first snap-fit ​​member 810 and the second snap-fit ​​member 910 is a snap-fit ​​slot, and the other of the first snap-fit ​​member 810 and the second snap-fit ​​member 910 is a resilient arm with a snap fastener. This application illustrates this illustratively using the example of the first snap-fit ​​member 810 having a snap-fit ​​slot and the second snap-fit ​​member 910 having a resilient arm with a snap fastener. When snap-fit ​​is required, the snap fastener in the resilient arm can pass through the snap-fit ​​slot and snap-fit ​​with the adapter frame 800.

[0104] In the embodiments of this application, such as Figure 14 and Figure 15 As shown, the adapter frame 800 may also have multiple first positioning parts 820, and the decorative part 900 may also have multiple second positioning parts 920. Here, the multiple first positioning parts 820 and the multiple second positioning parts 920 can be matched one-to-one to achieve positioning of the adapter frame 800 and the decorative part 900.

[0105] For example, the first positioning part 820 may have a positioning opening V5, and the second positioning part 920 may be a positioning post for insertion into the corresponding positioning opening V5. Thus, during the assembly of the adapter frame 800 and the decorative part 900, multiple positioning posts on the decorative part 900 can be inserted into the corresponding positioning openings V5 to achieve initial positioning between the decorative part 900 and the adapter frame 800. Then, the decorative part 900 can be pressed firmly so that multiple second snap-fit ​​pieces 910 on the decorative part 900 can snap into the corresponding first snap-fit ​​pieces 810 on the adapter frame 800.

[0106] Furthermore, the positioning cooperation between the plurality of first positioning parts 820 on the adapter frame 800 and the plurality of second positioning parts 920 on the decorative part 900 can prevent the decorative part 900 from rotating relative to the adapter frame 800, thereby ensuring high stability of the decorative part 900 on the housing 100.

[0107] In one possible implementation, such as Figure 12 As shown, the adapter frame 800 is also provided with at least one second limiting member 830, and at least one of the multiple first positioning parts 820 on the adapter frame 800 can also be reused as the second limiting member 830. The housing 100 may also have multiple second limiting notches Z2, each of which can be located at the position of the light-emitting opening V2 and can communicate with the light-emitting opening V2. Here, the multiple second limiting notches Z2 can correspond one-to-one with the multiple second limiting members 830, and at least a portion of each second limiting member 830 can be located within the corresponding second limiting notch Z2.

[0108] In this application, during the assembly process of the adapter 800 and the housing 100, after the adapter 800 is initially installed inside the housing 100, the adapter 800 can be initially limited by the cooperation of multiple second limiting members 830 and multiple second limiting notches Z2, so as to ensure that the adapter 800 can be better assembled with the housing 100.

[0109] In summary, the projection device provided in this application includes: a housing, a main bracket, a camera module, and a projector body. Since the camera module can be mounted and fixed on a first mounting position on the main bracket, and the projector body can be mounted and fixed on a second mounting position on the main bracket, the camera module and the projector body are mounted on the same main bracket, and the relative positions between the first and second mounting positions on the main bracket are fixed. This ensures that the relative positions between the camera module and the projector body are also fixed. Thus, even if the projection device is disassembled for repair, the relative positions between the camera module and the projector body remain fixed after reassembly. This ensures that the projection device effectively corrects the image projected by the projector body based on the camera module, resulting in better image display. Furthermore, even if the projection device is disassembled for repair, there is no need to recalibrate the relative positions between the camera module and the projector body, simplifying the use of the projection device.

[0110] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0111] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
