[0037] With the rapid development of vehicle technology and the increasing demand of users for in-vehicle entertainment and information display functions, vehicle display devices have become an important part of vehicles. Traditional vehicle display devices mainly use fixed display screens such as liquid crystal screens and organic light-emitting diode (OLED) screens, but these display devices have certain limitations in terms of visual range, flexibility and aesthetics.

[0038] As a new technology, vehicle-mounted projectors use projection principles to project information onto a pre-installed screen in the vehicle. Compared with traditional display devices, vehicle-mounted projectors have the following advantages: they can provide a larger display area, suitable for the presentation of audio-visual entertainment content and driving assistance information; the projection area can be adjusted as needed, reducing the occupation of the vehicle space; projection technology can enhance the technological feel of the vehicle, while improving the integration and simplicity of the interior design, etc.

[0039] Although the vehicle-mounted projection technology has been preliminarily applied to some vehicles, there are still some problems. For example, due to the production error and assembly error of the vehicle body and the projector itself, the projection picture of the projector cannot be exactly and completely projected on the target. Therefore, in the related technology, light with a projection coverage larger than the size of the screen is used, that is, the projection picture will exceed the screen, and then the projection picture is cut after calibration, so as to make the cut projection picture cover the entire screen. Therefore, a calibration device which is convenient for quick disassembly and assembly with the projection equipment is needed to reduce the cost of the camera for calibration built in the projector.

[0040] The embodiment of the present application provides a calibration device of a projection equipment, Figure 2 、 Figure 3 and Figure 1 , Figure 1 a structure diagram of the calibration device of the projection equipment provided by the present application Figure 2 , Figure 2 a structure diagram of the calibration device of the projection equipment provided by the present application Figure 3 , Figure 4 a sectional structure diagram of the calibration device of the projection equipment provided by the present application.

[0041] The calibration device of the projection equipment provided by the embodiment of the present application comprises a shell 1, an acquisition assembly 2 and a fixing piece 3. The shell 1 has a containing cavity 11; the acquisition assembly 2 is arranged in the containing cavity 11, and the acquisition assembly 2 is used for acquiring a calibration image; and the fixing piece 3 is arranged on the shell 1 and matched with the projection equipment, and can be detachably connected with the projection equipment.

[0042] In the embodiment of the present application, the structure of the shell 1 can be set according to the structure of the acquisition assembly 2 and the structure of the part of the projection equipment which can be connected with the calibration device.

[0043] For example, the shell 1 can be made of plastic, metal or the like, and can be set as a structure similar to a cuboid. The containing cavity 11 can be arranged in the shell 1 according to the size and shape of the acquisition assembly 2, so as to facilitate the installation of the acquisition assembly 2 in the containing cavity 11 of the shell 1, and to provide protection for the acquisition assembly 2 by the shell 1. A plug hole can also be arranged on the shell 1, so as to connect the lead wire with the socket on the acquisition assembly 2 through the plug hole, so that the acquisition assembly 2 can be electrically connected with the projection equipment through the lead wire.

[0044] In the embodiment of the present application, the acquisition assembly 2 can adopt a structure comprising a camera and a mainboard, so as to shoot the calibration image by the camera, control the camera by the mainboard, and transmit data with the projection equipment. The calibration image can be a picture comprising a screen and a projection picture.

[0045] In the embodiments of the present application, the structure of the fixing member 3 can be set according to the structure on the projection device, so as to install or remove the calibration device on the projection device through the fixing member 3. The fixing member 3 can be arranged on the shell 1. For example, the shell of the projection device usually has structures such as holes, protrusions, grooves, etc. The structure of the fixing member 3 can be set according to the structures such as holes, protrusions, grooves, etc. on the shell of the projection device, so that at least a part of the fixing member 3 matches the structures such as holes, protrusions, grooves, etc. on the shell of the projection device. In this way, the calibration device can be detachably connected to the shell of the projection device through plug-in, clamping, adsorption, bonding or the like.

[0046] The calibration device of the projection device provided by the embodiments of the present application can collect the calibration image of the projection picture through the collection assembly 2, which is arranged in the shell 1, so as to facilitate the calibration of the projection picture of the projection device. In addition, the fixing member 3 is arranged on the shell 1, so that the calibration device can be quickly connected to the projection device through the fixing member 3, and after the calibration is completed, the calibration device can be removed from the projection device through the fixing member 3, so that the quick assembly and disassembly with the projection device can be realized, and the calibration device can be repeatedly used, thereby being beneficial to reducing the cost of the projection device.

[0047] In some possible embodiments of the present application, refer to Figure 5 and Figure 4 , Figure 1 The calibration device of the projection device provided by the present application is applied to Figure 5 , Figure 2 The calibration device of the projection device provided by the present application is applied to Figure 3 The fixing member 3 includes a connecting portion 31, which matches the connecting port 61 of the projection device, and the connecting portion 31 can be detachably connected to the connecting port 61.

[0048] In the embodiments of the present application, the projection device usually has a connecting port 61, so as to plug in an external device (such as a U disk, a memory card or the like) through the connecting port 61, or to realize the communication between the inside and outside of the projection device through the connecting port 61. The shape of the fixing member 3 can be set according to the shape of the connecting port 61 on the projection device, so as to facilitate the detachable connection of the fixing member 3 and the connecting port 61.

[0049] Exemplarily, the shape of the fixing member 3 can be set according to the shape of the connecting port 61. For example, a part of the fixing member 3 can be set to match the structure of a universal serial bus (USB) port, a high definition multimedia interface (HDMI), an auxiliary (AUX) interface, or the like, or the shape of the fixing member 3 can be set according to the shape of an air inlet or an air outlet on the shell of the projection device. For example, the connecting portion 31 on the fixing member 3 can be set to match the shape of the air outlet, so that the connecting portion 31 is inserted into the air outlet or the connecting portion 31 is clamped on the edge of the air outlet.

[0050] In the above embodiments, the shape of the connecting portion 31 of the fixing member 3 is set according to the shape of the connecting port 61 of the projection device, so that the connecting portion 31 matches the connecting port 61, and the connecting portion 31 and the connecting port 61 are connected by insertion or clamping, and the calibration device can be quickly and detachably installed at the connecting port 61 of the projection device.

[0051] In some possible embodiments of the present application, as shown in Figure 5 The connecting portion 31 includes a clamping segment 311 and a guide segment 312, the clamping segment 311 is close to the shell 1, the guide segment 312 is connected to one end of the clamping segment 311 away from the shell 1, the guide segment 312 and the clamping segment 311 have an included angle that is an acute angle, the connecting port includes an air vent, and the clamping segment 311 is used for clamping on the edge of the air vent of the projection device.

[0052] In the embodiments of the present application, the shell of the projection device is usually provided with air vents, such as air inlets and air outlets, to exchange air between the inside and the surrounding environment of the projection device through the air inlets and the air outlets, so as to cool the heat generating components in the projection device. The air vent usually includes a plurality of through holes, which can be circular holes or approximately rectangular long strip-shaped holes. The connecting portion 31 can be set to a structure that can be clamped in the air vent.

[0053] Exemplarily, the connecting portion 31 can be set to a structure including the clamping segment 311 and the guide segment 312. The extension direction of the clamping segment 311 is perpendicular or close to perpendicular to the first direction X in which the calibration device approaches or moves away from the projection device, or the extension direction of the surface of the clamping segment 311 clamped on the edge of the air vent is perpendicular or close to perpendicular to the first direction X. For example, two connecting portions 31 can be provided on the fixing member 3, that is, one clamping segment 311 can be provided on each end of the fixing member 3.

[0054] Another example, a guide section 312 can be arranged at one end of the clamping section 311 away from the shell 1. For example, the guide section 312 can have an included angle of 0-90° with the extending direction of the clamping section 311, such as an included angle of 40°, 45° or 50° between the guide section 312 and the clamping section 311. In this way, as shown in Figure 2 the guide section 312 can first contact the edge of the air vent and generate sliding friction with the edge of the air vent to guide the clamping section 311 to move into the air vent during the process of clamping the clamping section 311 into the air vent, until the clamping section 311 is completely moved into the air vent.

[0055] In the above embodiment, since the connecting part 31 includes the clamping section 311 and the guide section 312, the fixing part 3 can be clamped to the edge of the air vent by the clamping section 311 to realize the clamping of the calibration device to the projection device. During the process of clamping the clamping section 311 into the air vent, the guide section 312 can guide the clamping section 311 to move into the air vent by the inclined guide section 312, so as to facilitate the clamping section 311 to be quickly clamped into the air vent.

[0056] In some possible embodiments of the present application, as shown in Figure 2 the fixing part 3 further includes a deformation part 32, one end of the deformation part 32 is connected to the shell 1, and the connecting part 31 is connected to the other end of the deformation part 32 away from the shell 1; the deformation part 32 can be displaced relative to the shell 1 under the action of an external force to drive the connecting part 31 to move relative to the connecting port 61.

[0057] In the embodiment of the present application, the deformation part 32 can be arranged in the fixing part 3 to drive the connecting part 31 to move relative to the connecting port 61 by the deformation part 32. For example, the deformation part 32 can be arranged in a sheet shape to facilitate the deformation of the deformation part 32 under the action of an external force. One end of the deformation part 32 can be connected to the shell 1, and the connecting part 31 can be arranged at the other end of the deformation part 32 away from the shell 1, that is, the clamping section 311 is connected to the other end of the deformation part 32 away from the shell 1.

[0058] In the above embodiment, since the deformation part 32 is arranged in the fixing part 3 and the connecting part 31 is connected to the deformation part 32, during the process of installing the calibration device at the position of the connecting port 61 of the projection device or disassembling the calibration device from the connecting port 61, an external force can be applied to the deformation part 32 to displace the deformation part 32 relative to the shell 1, so that the deformation part 32 can drive the connecting part 31 to move relative to the connecting port 61, and then facilitate the clamping of the connecting part 31 into the connecting port 61 or the withdrawal of the connecting part 31 from the connecting port 61.

[0059] In some possible embodiments of the present application, as shown in Figure 3 and Figure 3As shown, the fixing member 3 further comprises a fixing portion 33 connected with the shell 1, and the deformation portion 32 extends from one end of the fixing portion 33, and the connecting portion 31 extends from one end of the deformation portion 32 away from the fixing portion 33.

[0060] In the embodiments of the present application, the fixing portion 33 can be arranged in the fixing member 3 to mount the fixing member 3 on the shell 1 through the fixing portion 33. For example, the fixing member 3 can be made of stainless steel, alloy, plastic or the like, can be arranged in a sheet shape, and the connecting portion 31, the deformation portion 32 and the fixing portion 33 can be formed on the fixing member 3 by bending or the like.

[0061] For example, the fixing portion 33 can be in a long strip shape, one deformation portion 32 can be arranged at each end of the fixing portion 33, and one connecting portion 31 can be arranged at one end of each deformation portion 32 away from the fixing portion 33. The fixing portion 33 and at least a part of the deformation portion 32 can be arranged in the groove on the shell 1, and the fixing portion 33 can be connected with the shell 1 by adhesion, clamping, threaded connection or the like.

[0062] In the above embodiments, the fixing portion 33 is arranged in the fixing member 3, which facilitates the connection of the fixing member 3 with the shell 1 through the fixing portion 33. The deformation portion 32 can be extended from the fixing portion 33, which facilitates the processing of the fixing member 3.

[0063] In some possible embodiments of the present application, the fixing portion 33 has a first connecting structure, the shell 1 has a second connecting structure matched with the first connecting structure, and the first connecting structure and the second connecting structure cooperate to detachably connect the fixing portion 33 with the shell 1.

[0064] In the embodiments of the present application, the fixing member 3 can be detachably connected with the shell 1. For example, the fixing portion 33 and the shell 1 can be respectively provided with matched connecting structures to realize the detachable connection of the fixing member 3 with the shell 1 through the matched connecting structures.

[0065] For example, the first connecting structure can comprise a through hole matched with a screw, and the second connecting structure can comprise a threaded hole matched with the screw, so that a screw as a fastener 5 can be used to detachably mount the fixing member 3 on the shell 1. The first connecting structure and the second connecting structure can also be a matched clamping groove and a clamping buckle respectively, and the first connecting structure and the second connecting structure can also be a matched clamping hole and a clamping column respectively, so as to detachably mount the fixing member 3 on the shell 1 by clamping.

[0066] In the above embodiment, since the first connecting structure and the second connecting structure are arranged on the fixing part 33 and the shell 1 respectively, the fixing part 3 can be detachably mounted on the shell 1 through the first connecting structure and the second connecting structure. In this way, different fixing parts 3 can be designed according to the structures of the connecting port 61 and the like on different projection devices, and the fixing part 3 can be conveniently replaced, thereby facilitating reduction of the design cost of the calibration device applied to projection devices with different structures.

[0067] In some possible embodiments of the present application, as shown in Figure 2 and Figure 5 The calibration device of the projection device further includes a pressing part 12, which is connected to the shell 1 and corresponds to the deformation part 32. The pressing part 12 can drive the deformation part 32 to move under the action of a force towards the deformation part 32.

[0068] In the embodiments of the present application, the pressing part 12 can be arranged on the shell 1 at a position corresponding to the deformation part 32, so as to apply an external force to the deformation part 32 by pressing the pressing part 12. For example, the pressing part 12 can be arranged in a structure including a sliding block and a compression spring. The sliding block can be arranged on the shell 1 to slide in the second direction Y, and a part of the movement path of the sliding block can coincide with a part of the deformation part 32. The compression spring can be arranged between the sliding block and the shell 1, so as to apply a force to the sliding block to drive the sliding block to move away from the shell 1 in the second direction Y.

[0069] In the above embodiment, since the pressing part 12 is arranged on the shell 1 and corresponds to the deformation part 32, the pressing part 12 can be pressed to move relative to the shell 1, so that an external force can be applied to the deformation part 32 by the pressing part 12 to drive the deformation part 32 to move relative to the shell 1.

[0070] In some possible embodiments of the present application, as shown in Figure 5 The pressing part 12 includes a pressing part 121 and an extension part 122. The extension part 122 is formed by extending from the body of the shell 1, and the pressing part 121 is connected to the extension part 122 and corresponds to the deformation part 32.

[0071] In the embodiments of the present application, the pressing part 12 can be formed by extending from the shell 1, that is, the pressing part 12 and the body of the shell 1 are in an integrated structure.

[0072] The housing 1 can be made of plastic, metal or other materials. The pressing member 12 can be provided in a structure including a pressing portion 121 and an extending portion 122. The extending portion 122 can be formed extending from the body of the housing 1, for example, the extending portion 122 can be provided in a sheet shape so that the extending portion 122 is easy to be deformed by bending. The pressing portion 121 can be provided in a block shape, and the pressing portion 121 is connected to one end of the extending portion 122 away from the body of the housing 1, and a part of the pressing portion 121 corresponds to the deformed portion 32 of the fixing member 3. For example, the pressing portion 121 can abut against the deformed portion 32, or there is a gap between the pressing portion 121 and the deformed portion 32, for example, the gap between the pressing portion 121 and the deformed portion 32 is 0.5mm to 1mm. The housing 1 can be processed by injection molding so that the pressing member 12 and the body of the housing 1 are integrally formed. The pressing member 12 and the body of the housing 1 can also be fixedly connected by bonding or welding.

[0073] In the above embodiment, since the pressing member 12 is provided in a structure including the extending portion 122 and the pressing portion 121, the pressing portion 121 is easy to move relative to the body of the housing 1 through the extending portion 122, so that the deformed portion 32 can be driven to move relative to the housing 1 by the pressing portion 121.

[0074] In some possible embodiments of the present application, as shown in Figure 1 and Figure 3 The housing 1 has a guide portion 13 matched with the connecting port 61. When the connecting portion 31 is connected with the connecting port 61 and limits the separation of the calibration device from the projection device along the first direction X, the guide portion 13 is connected with the connecting port 61, which can limit the movement of the calibration device relative to the connecting port 61 along the second direction Y, and the second direction Y and the first direction X satisfy a perpendicular relationship.

[0075] In the embodiment of the present application, after the calibration device is installed on the projection device by the fixing member 3, the calibration device can move relative to the projection device. The guide portion 13 can be provided on the housing 1 to limit the movement of the calibration device relative to the projection device through the guide portion 13.

[0076] For example, the guide portion 13 can be provided on one side of the housing 1 where the fixing member 3 is provided, and the guide portion 13 can be matched with the connecting port 61 on the shell of the projection device so that the guide portion 13 can be inserted into the connecting port 61. For example, the guide portion 13 can be provided in a block shape close to the shape of the connecting port 61, for example, four protrusions can be provided on the surface of the housing 1 where the fixing member 3 is provided, and the four protrusions are distributed in a rectangular shape. The protrusions can be provided in a quadrangular pyramid shape, that is, the area of one end of the protrusion away from the center of the housing 1 is smaller than the area of the other end of the protrusion connected with the body of the housing 1. For example, ​As shown, in the process of installing the calibration device on the projection device, the protrusion as the guide portion 13 can be inserted into the connecting port 61 of the projection device and abut against the edge of the connecting port 61. In this way, when the connecting portion 31 of the fixing member 3 is clamped with the edge of the connecting port 61 to limit the calibration device from separating from the projection device along the first direction X, the guide portion 13 can limit the movement of the calibration device relative to the connecting port 61 along the second direction Y. The second direction Y is perpendicular or close to perpendicular to the first direction X.

[0077] In the above embodiment, since the guide portion 13 is arranged on the shell 1, after the calibration device is installed on the projection device, the guide portion 13 can extend into the connecting port 61 of the projection device, so that the movement of the calibration device relative to the projection device along the second direction Y can be limited by the guide portion 13, and the calibration device can be kept in a fixed position relative to the projection device.

[0078] In some possible embodiments of the present application, as shown in ​ and ​ The calibration device of the projection device further includes a protective member 4, which is arranged at the opening of the accommodating cavity 11 and through which the light is transmitted to the acquisition assembly 2.

[0079] In the embodiments of the present application, the protective member 4 can be arranged on the shell 1. For example, the protective member 4 can be made of transparent glass, transparent plastic plate or other materials that can allow light to pass through. The protective member 4 can be arranged at the opening of the accommodating cavity 11 of the shell 1, that is, the protective member 4 is on the shooting path of the acquisition assembly 2. The protective member 4 can be fixed on the shell 1 by adhesion, clamping or other ways.

[0080] In the above embodiment, since the protective member 4 is arranged at the opening of the shell 1, the acquisition assembly 2 can be shielded and protected by the protective member 4, which is conducive to reducing the situation that the acquisition assembly 2 is collided or dust falls on the acquisition assembly 2.
