Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of projectors, and more particularly to a mounting device applied to a projection device and the projection device. BACKGROUND

[0002] In existing electrical equipment (for example, a projector), in order to adapt to the application site, a support is usually needed to support and fine-tune the installation position when in use. Taking a projector as an example, when a user uses the projector to project, the projector can be usually installed on a support, and the support is placed in the use site, for example, placed in a car to project on a car window, placed on the floor to project on a specific curtain or wall, etc.

[0003] However, in actual application scenarios, after the support is properly placed, when the projector projects on the projection surface, there may be a situation that the projection picture area is skewed, which requires the support to have an adjusting function or adjusting mechanism to allow the user to adjust the spatial position of the projector, so as to correct the display area of the projection picture.

[0004] In the adjusting mechanism of the commonly used support, the spatial position of the projector is usually adjusted by a plurality of interval distributed bolts, for example, three bolts at different points are used to adjust the support to adjust the levelness of the projector, so as to realize the physical correction of the display area. However, such adjusting structure occupies a large space, the distribution distance of the adjusting points is large, and the user needs to displace more hand positions to complete the adjustment, and the operation is relatively cumbersome.

[0020] In a second aspect, the embodiments of the present application further provide a projection device, which comprises a projection light engine and the mounting device according to any one of the above.

[0021] Compared with the prior art, the mounting device provided by the embodiments of the present application can be used for mounting a machine body of an electronic device, and can be used as a support of the machine body, for example, a projection light engine or the like. Taking the projection light engine as an example, the mounting device provided by the embodiments of the present application can be used for mounting the projection light engine and can be used as a support of the projection light engine. The mounting device comprises a fixed seat, a bearing seat, a linkage, a limiting mechanism and an adjusting mechanism. The bearing seat is used for bearing the projection light engine. The bearing seat and the fixed seat can be directly or indirectly drivingly connected through the linkage. The adjusting mechanism is connected between the bearing seat and the fixed seat. When a part of the adjusting mechanism moves relative to the bearing seat or the fixed seat, the position of the bearing seat relative to the fixed seat can be adjusted, so that the spatial position of the projection light engine is adjusted.

The adjusting rod is movably arranged along the first axis in the limiting mechanism, and is detachably connected with the first adjusting member. The first adjusting member is adjustably arranged in the fixed seat. When the adjusting rod is connected with the first adjusting member, the rotating movement of the adjusting rod drives the first adjusting member to move along the first axis, so that the bearing seat produces a rotating movement about the second axis under the driving action of the linkage. Therefore, when it is necessary to adjust the spatial angle of the projection light engine about the second axis, the user only needs to rotate the adjusting rod.

[0023] Further, the adjusting rod is also detachably connected with the second adjusting member. When the adjusting rod is connected with the second adjusting member, the rotating movement of the adjusting rod drives the second adjusting member to move to drive the bearing seat to rotate about the first axis. Therefore, when it is necessary to adjust the spatial angle of the projection light engine about the first axis, the user only needs to rotate the adjusting rod. It can be seen that the user can realize the adjustment of two degrees of freedom of the projection light engine in space through one adjusting mechanism. Therefore, the space position occupied by the adjusting mechanism of the embodiments of the present application is relatively small, and the user operation is relatively convenient.

[0024] In addition, since the adjusting rod is detachably connected with the first adjusting member and the second adjusting member respectively, when the adjusting rod is connected with the first adjusting member and the second adjusting member, the transmission connection relationship between the adjusting rod and the bearing seat can be established, so that the adjusting function of the mounting device (as described above) can be conveniently realized, and when the adjusting rod is separated from the first adjusting member and / or the second adjusting member, the transmission connection relationship between the adjusting rod and the bearing seat in at least one of the two degrees of freedom can be cut off, so that the spatial position change of the bearing seat caused by accidental touch of the adjusting rod is avoided, and the positioning after adjustment is more reliable.

[0035] In order to make persons skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work shall fall within the scope of protection of the present application.

[0036] Referring to Figure 1 The mounting device 100 is used for mounting a body of an electronic device, and serves as a support of the body to support the body and adjust the spatial position of the body. The body may, for example, be a projection light machine or the like. The body in the embodiments of the present application is mounted on the mounting device 100 in a manner of Figure 1 The projection light machine 200 shown in the figure is taken as an example for description.

[0037] The embodiments of the present application further provide a projection device 300 provided with the mounting device 100, the projection device 300 comprising the mounting device 100 and the projection light machine 200. The projection light machine 200 is used for projecting designated image content toward a designated projection receiving surface, which may be a projection screen, a projection screen, a window glass, a wall surface or a light waveguide, etc. capable of reflecting or presenting a display picture. The projection light machine 200 may comprise a housing 202, an image source 204 and a projection lens 206, the image source 204 and the projection lens 206 being arranged inside the housing 202. The image source 204 is used for generating pattern / image light rays for projection, and the projection lens 206 is used for guiding the light rays out to the designated projection receiving surface. In actual application, the projection light machine 200 is mounted on the mounting device 100 through the housing 202.

[0038] Referring to Figure 2In the embodiment of the present application, the mounting device 100 comprises a fixing base 10, a bearing base 30, a linkage 50, a limiting mechanism 70 and an adjusting mechanism 90. The fixing base 10 is used to be installed in the use place of the mounting device 100 (for example, the ground, the desktop, etc.). The bearing base 30 is stacked on the fixing base 10 and is used to install the body of the electronic device (for example, the projection light machine 200 mentioned above). The linkage 50 is drivingly connected between the bearing base 30 and the fixing base 10. The limiting mechanism 70 is connected to the fixing base 10. The adjusting mechanism 90 is arranged on the limiting mechanism 70 and is connected to the fixing base 10. The adjusting mechanism 90 comprises an adjusting rod 92, a first adjusting part 94 and a second adjusting part 96. The first adjusting part 94 is adjustably arranged on the fixing base 10 and can move along the direction of the first axis Z relative to the fixing base 10 under the action of external force. The second adjusting part 96 is drivingly connected with the bearing base 30. The adjusting rod 92 is movably arranged along the first axis Z in the limiting mechanism 70 and is detachably connected with the first adjusting part 94 and the second adjusting part 96.

[0039] The adjusting rod 92 has the freedom of movement along the first axis Z and the freedom of rotation around the first axis Z relative to the limiting mechanism. When the adjusting rod 92 is connected with the first adjusting part 94, the rotating movement of the adjusting rod 92 is converted into the moving movement of the first adjusting part 94 along the first axis Z, so that the bearing base 30 rotates around the second axis X under the driving action of the linkage 50. The second axis X and the first axis Z intersect with each other. When the adjusting rod 92 is connected with the second adjusting part 96, the rotating movement of the adjusting rod 92 is converted into the rotating movement of the bearing base 30 around the first axis Z through the second adjusting part 96, wherein the second adjusting part 96 acts as the driving part for transmitting the movement of the adjusting rod 92. In the embodiment of the present application, the second axis X and the first axis Z can be perpendicular to each other or form a certain angle (for example, 60°, 30°, etc.) with each other. For example, the first axis Z can be the axis of the direction of gravity and the second axis X can be the axis of the horizontal direction.

[0040] Therefore, in the mounting device 100 mentioned above, the bearing base 30 is used to bear the projection light machine 200. The bearing base 30 and the fixing base 10 can be directly or indirectly drivingly connected through the linkage 50. The adjusting mechanism 90 is connected between the bearing base 30 and the fixing base 10. When the parts of the adjusting mechanism 90 move relative to the bearing base 30 or the fixing base 10, the position of the bearing base 30 relative to the fixing base 10 can be adjusted, so that the spatial position of the projection light machine 200 is adjusted.

[0041] Further, the adjusting rod 92 of the adjusting mechanism 90 has the freedom of movement along the first axis Z and the freedom of rotation around the first axis Z relative to the limiting mechanism 70. When the adjusting rod 92 is connected with the first adjusting member 94, the rotation movement of the adjusting rod 92 drives the first adjusting member 94 to move along the first axis Z, so that the carrier 30 generates the rotation movement around the second axis X under the transmission of the linkage 30. Therefore, when it is necessary to adjust the spatial angle of the projection light machine 200 relative to the second axis X, the user only needs to rotate the adjusting rod 92.

[0042] Further, when the adjusting rod 92 is connected with the second adjusting member 96, the rotation movement of the adjusting rod 92 drives the second adjusting member 96 to move so as to drive the carrier 30 to rotate around the first axis Z. Therefore, when it is necessary to adjust the spatial angle of the projection light machine 200 relative to the first axis Z, the user only needs to rotate the adjusting rod 92. It can be seen that the user can realize the adjustment of the two degrees of freedom of the projection light machine 200 in the three-dimensional space through one adjusting mechanism 90. Therefore, the adjusting mechanism 90 of the embodiment of the present application has a relatively compact structure and occupies a relatively small space position, and the user can operate conveniently.

[0043] In addition, since the adjusting rod 92 is detachably connected with the first adjusting member 94 and the second adjusting member 96, when the adjusting rod 92 is connected with the first adjusting member 94 and the second adjusting member 96, the transmission connection relationship between the adjusting rod 92 and the carrier 30 can be established, so that the adjusting function of the mounting device 100 (as described above) can be realized conveniently. When the adjusting rod 92 is separated from the first adjusting member 94 and / or the second adjusting member 96, the transmission connection relationship between the adjusting rod 92 and the carrier 30 in at least one of the two degrees of freedom can be cut off, so that the spatial position change of the carrier 30 caused by the accidental touch of the adjusting rod 92 can be avoided, and the positioning after the adjustment is more reliable.

[0044] Hereinafter, some possible specific implementation modes of the mounting device 100 will be described.

[0045] Please refer to Figure 2 In the embodiment, the fixed seat 10 is used as the base support of the mounting device 100, and is used to be fixedly installed in the use place (such as the ground, the desktop, etc.) of the mounting device 100. The specific structure of the fixed seat 10 is not limited in the embodiment of the present application, and the fixed seat 10 can be a fixedly installed block, a plate or a frame structure, etc. In the embodiment, the fixed seat 10 includes the supporting legs 12 and the fixed plate 14. The number of the supporting legs 12 is plural, and the plural supporting legs 12 are arranged at one side of the fixed plate 14 at intervals and are used to support the fixed plate 14.

[0046] The bearing seat 30 is arranged on the fixing seat 10. Specifically, in the embodiment, the bearing seat 30 is stacked on the fixing plate 14 and movably connected with the fixing plate 14. The bearing seat 30 comprises a bearing plate 32 for mounting the projection light machine 200, and the bearing plate 32 is movably connected with the fixing plate 14. In the embodiment, the bearing plate 32 and the fixing plate 14 are respectively provided with hollow parts (not marked in the figure) in communication with each other, which can be used for corresponding heat dissipation parts of the projection light machine 200, so as to facilitate the heat generated by the projection light machine 200 to be dissipated through the hollow parts.

[0047] The movable connection between the bearing seat 30 and the fixing seat 10 can be realized by threaded fastener connection, or by mechanical buckle form, and the two can be provided with elastic members or flexible members and the like structures to realize relative movement under external force. In the embodiment, the bearing seat 30 comprises opposite first end 321 and second end 323, specifically, the first end 321 and the second end 323 are respectively located at both ends of the bearing plate 32, and the part between the first end 321 and the second end 323 is used for mounting the body of the electronic equipment (such as the projection light machine 200 mentioned above).

[0048] The bearing plate 32 is movably connected with the fixing plate 14 through the first end 321 and the second end 323. Specifically, in the embodiment, the mounting device 100 further comprises an elastic connection assembly 80, which is arranged at the second end 323 and elastically connected between the bearing seat 30 and the fixing seat 10. When the first end 321 is pushed by external force, based on the elastic deformation ability of the elastic connection assembly 80, the bearing plate 32 can present a certain displacement relative to the fixing seat 10, so that the projection light machine 200 on the bearing plate 32 changes the spatial position.

[0049] The elastic connection assembly 80 comprises a fastener 82 and an elastic abutting member 84, the fastener 82 is sequentially arranged in the elastic abutting member 84, the bearing seat 30 and connected with the fixing seat 10. The elastic abutting member 84 is elastically abutted between the fastener 82 and the bearing seat 30.

[0050] In the embodiment, the fastener 82 is a threaded fastener such as a bolt or screw, and includes a bolt head 821 and a bolt portion 823 connected to each other, and the axis direction of the bolt portion 823 is substantially parallel to the first axis Z. The bolt portion 823 is sequentially arranged in the abutting member 84, the bearing seat 30, and is threadedly connected with the fixing seat 10. The elastic abutting member 84 can be an elastic sleeve (such as a plastic sleeve, a rubber sleeve, or the like), or a spring, and is sleeved on the outer periphery of the bolt portion 823 and elastically abuts between the bolt head 821 and the bearing plate 32. The elastic abutting member 84 is made of an elastic material and has an elastic deformation capability, and due to the elastic abutment between the bolt head 821 and the bearing plate 32, the elastic abutting member 84 has an elastic deformation capability in the direction parallel to the first axis Z. Since the elastic abutting member 84 is sleeved on the outer periphery of the bolt portion 823, the structure of the elastic abutting member 84 itself has a structure extending in the direction perpendicular to the first axis Z (for example, the direction of the second axis X), so that the elastic abutting member 84 also has an elastic deformation capability in the direction perpendicular to the first axis Z.

[0051] Therefore, when the first end 321 of the bearing plate 32 is subjected to a thrust force or a pulling force substantially along the first axis Z, based on the elastic deformation capability of the elastic abutting member 84 in the direction of the first axis Z, the elastic abutting member 84 can be compressed by the bearing plate 32, and due to the connecting limiting effect of the fastener 82, the first end 321 of the bearing plate 32 can have an angular displacement about the elastic connecting assembly 80 in this case, and the axis of rotation is the same direction as the second axis X (which can also be understood as the second axis X). In short, when the first end 321 is subjected to a thrust force or a pulling force substantially along the first axis Z, based on the elastic connection structure of the second end 323, the bearing plate 32 will have a rotational movement about the second axis X, thereby changing the spatial angle of the bearing plate 32 about the second axis X. In addition, when the first end 321 of the bearing plate 32 is subjected to a thrust force or a pulling force substantially along the direction perpendicular to the first axis Z (for example, along the direction of the second axis X), based on the elastic deformation capability of the elastic abutting member 84 in the direction perpendicular to the first axis Z (for example, along the direction of the second axis X), the bearing plate 32 will rotate about the first axis Z, thereby changing the spatial angle of the bearing plate 32 about the first axis Z. Similarly, if the first end 321 of the bearing plate 32 is subjected to a torque about the first axis Z, based on the elastic deformation capability of the elastic abutting member 84, the bearing plate 32 will rotate about the first axis Z, thereby changing the spatial angle of the bearing plate 32 about the first axis Z.

[0052] In the present embodiment, the number of elastic connecting assemblies 80 is two, and the two elastic connecting assemblies 80 are spaced apart on the second end 323, so as to ensure the stability of the connection of the bearing plate 32. The two elastic connecting assemblies 80 are arranged in a spaced apart manner along the direction of the second axis X, so as to avoid interference with the rotation of the bearing plate 32, and make the movement of the position adjustment of the bearing plate 32 more smooth. In other embodiments, the fastener 82 can be realized by using a mechanical connection structure other than a threaded fastener, for example, a mechanical buckle is connected between the bearing plate 32 and the fixed plate 14, and the elastic abutting piece 84 is abutted / clamped between the fastener 82 and the bearing plate 32.

[0053] In the present embodiment, the limiting mechanism 70 and the adjusting mechanism 90 are both arranged on the first end 321, and the adjusting mechanism 90 directly or indirectly applies the above-mentioned pushing force or pulling force / torque to the first end 321, so as to change the spatial angle of the bearing plate 32 about the second axis X and the first axis Z. The way in which the adjusting mechanism 90 applies the above-mentioned pushing force or pulling force / torque to the first end 321 of the bearing seat 30 can be realized by a transmission connection between the linkage 50 or / and the adjusting mechanism 90 itself and the bearing seat 30.

[0054] As an example, the linkage 50 is in transmission connection between the bearing seat 30 and the fixed seat 10, and when the adjusting rod 92 of the adjusting mechanism 90 is rotated or pulled by the user, the spatial position of the bearing seat 30 can be changed based on the linkage 50. In the present embodiment, the bearing plate 32 and the fixed plate 14 are stacked on each other along the first axis Z, and the linkage 50 is arranged on the first end 321 and located between the stacked bearing plate 32 and fixed plate 14. The linkage 50 can have elastic deformation capability, for example, the linkage 50 includes an elastic body which is clamped by the bearing plate 32 and the fixed plate 14, and the adjusting mechanism 90 connects the bearing plate 32 and the fixed plate 34 and keeps the distance between the bearing plate 32 and the fixed plate 34 at the first end 321. When the user changes the distance between the bearing plate 32 and the fixed plate 34 at the first end 321 through the adjusting mechanism 90, for example, so that the distance here increases, due to the elastic deformation recovery of the linkage 50, the linkage 50 can push the first end 321 of the bearing plate 32 away from the fixed plate 14, so as to form the above-mentioned pushing force along the first axis Z on the bearing plate 32.

[0055] In the embodiment, the number of the linkages 50 is two, which are spaced apart on the first end 321, so as to ensure uniform force exertion on the bearing plate 32. The two linkages 50 are spaced apart along the direction of the second axis X and are located on the two sides of the adjusting mechanism 90. In the embodiment, the linkage 50 can be an elastic pad, such as a rubber pad, a spring, etc. In order to limit the linkage 50, the bearing plate 32 and / or the fixed plate 14 can be provided with a hole or a groove structure for installing the linkage 50.

[0056] In other examples, the linkage 50 can be a rigid structure, for example, it can be a snap ring or a protruding structure, one end of which is connected to the adjusting rod 92 or the first adjusting member 94 of the adjusting mechanism 90, and the other end is in contact with or inserted into the bearing plate 32. When the adjusting rod 92 or the first adjusting member 94 generates displacement along the first axis Z, it can drive the linkage 50 to push or pull the bearing plate 32, so as to form the above-mentioned pushing force or pulling force along the first axis Z on the bearing plate 32. Taking the snap ring as an example, the outer periphery of the first adjusting member 94 is provided with a clamping groove, and the snap ring is partially embedded in the clamping groove. The bearing plate 32 can be provided with a through hole, and the inner wall of the through hole is provided with another clamping groove. The first adjusting member 94 is inserted into the through hole, and the other part of the snap ring is embedded in the other clamping groove, so as to realize the transmission connection between the linkage 50 and the bearing plate 32. In order to save space, other examples of the linkage 50 are not described here.

[0057] Please refer to Figure 3 In the embodiment, the first adjusting member 94 can generate the above-mentioned displacement along the first axis Z based on a threaded connection relationship. Specifically, the fixed plate 14 of the fixed seat 10 is provided with a threaded hole 141, and the hole axis of the threaded hole 141 is parallel or coincides with the first axis Z. The first adjusting member 94 is a threaded fastener such as a screw or a bolt. The first adjusting member 94 includes a head 941 and a screw rod 943 connected to the head 941. The screw rod 943 is inserted into the bearing plate 32 of the bearing seat 30 and is threadedly connected with the threaded hole 141. The head 941 is located on the side of the bearing plate 32 away from the fixed plate 14 and directly or indirectly abuts against the bearing plate 32, so as to limit the position relationship of the bearing plate 32 relative to the fixed plate 14. It can also be used to exert the pushing force of the figure along the first axis Z on the bearing plate 32, so as to change the rotation angle of the bearing plate 32 about the second axis X. When the first adjusting member 94 is rotated, the first adjusting member 94 is translated along the first axis Z relative to the bearing plate 32 based on the threaded connection relationship. For example, when the first adjusting member 94 is rotated in the direction of the arrow Z1 in the figure, the first adjusting member 94 is translated along the first axis Z in the direction of the arrow Z2 in the figure, so as to push the bearing plate 32 along the first axis Z, and when the first adjusting member 94 is rotated in the direction of the arrow Z2 in the figure, the first adjusting member 94 is translated along the first axis Z in the direction of the arrow Z1 in the figure, so as to pull the bearing plate 32 along the first axis Z. Figure 3When the head 941 is translated upward along the first axis Z, the head 941 has a tendency to move away from the carrier plate 32, so that the carrier plate 32 has a movement space upward along the first axis Z, at this time, the elastic abutting force of the linkage 50 drives the first end 321 of the carrier plate 32 to move upward, so that the carrier plate 32 generates a rotational movement about the second axis X based on the elastic connection assembly 80. Of course, in other embodiments, when the first adjusting member 94 is translated along the first axis Z relative to the carrier plate 32, the linkage 50 of other structures (for example, a clasp structure) can drive the first end 321 to move synchronously to change the rotation angle of the carrier plate 32 about the second axis X. In some embodiments, the head 941 can be in contact with the carrier plate 32 to achieve abutting, or abutting through other intermediate elements, for example, the head 941 can be indirectly abutted to the carrier plate through the second adjusting member 96.

[0058] In the embodiments of the present application, the movement action of the first adjusting member 94 is driven by the adjusting rod 92, and the connection relationship between the adjusting rod 92 and the first adjusting member 94 is a detachable transmission connection relationship. The transmission connection relationship between the adjusting rod 92 and the first adjusting member 94 can be realized by hole shaft cooperation, or can be realized by other mechanical connection relationships (for example, clamping cooperation). Please refer to Figure 4 , specifically in Figure 4 the embodiment shown, the adjusting rod 92 and the first adjusting member 94 are transmission connected through hole shaft cooperation, and the head 941 of the first adjusting member 94 away from the screw rod part 943 is provided with a first non-circular hole 9411, and the end of the adjusting rod 92 is provided with a first non-circular column 9201, and the cross-sectional profile of the first non-circular column 9201 is matched with the cross-sectional profile of the first non-circular hole 9411. The first non-circular column 9201 is detachably accommodated in the first non-circular hole 9411, and is used to abut the hole wall of the first non-circular hole 9411 when rotating to drive the first adjusting member 94 to rotate. In the embodiment, the first non-circular hole 9411 is a polygonal hole (for example, a hexagonal hole, etc.), and the first non-circular column 9201 is a polygonal prism (for example, a hexagonal prism, etc.); in other embodiments, the first non-circular hole 9411 can be an elliptical hole or other irregular hole, and the first non-circular column 9201 is an elliptical column or other irregular column, as long as it can ensure that the adjusting rod 92 can drive the first adjusting member 94 to rotate. When the user needs to adjust the rotation angle of the carrier plate 32 about the second axis X, only needs to rotate the adjusting rod 92 to drive the first adjusting member 94 to move along the first axis Z; when not needing to adjust the carrier plate 32, the first non-circular column 9201 is withdrawn from the first non-circular hole 9411, so that the adjusting rod 92 and the first adjusting member 94 are separated, which can avoid the non-intended displacement of the carrier plate 32 caused by the accidental touch of the adjusting rod 92, and the operation is convenient and reliable.

[0059] In other embodiments, the first adjusting member 94 can generate the displacement along the first axis Z based on a clamping connection relationship between protrusions and clamping slots. For example, a plurality of protrusions and clamping slots distributed along the first axis Z can be present between the first adjusting member 94 and the carrier plate 32, the protrusions and different clamping slots are matched, and the positions of the first adjusting member 94 on the first axis Z can be changed, so as to change the distance between the first end 321 of the carrier plate 32 and the fixed plate 14, and finally realize the rotation adjustment of the carrier plate 32 about the second axis X. For the sake of brevity, the present specification will not be elaborated one by one.

[0060] In the embodiments of the present application, the second adjusting member 96 is in transmission connection with the carrier plate 32, and the carrier plate 32 can generate rotation adjustment about the first axis Z under the driving of the second adjusting member 96. Specifically, please refer to FIG. 1 again, Figure 3 The second adjusting member 96 is sleeved on the outer periphery of the adjusting rod 92 and is rotatably arranged, and the outer periphery of the second adjusting member 96 is provided with meshing teeth 961. The carrier seat 30 further comprises a rack 34 connected to the carrier plate 32. The rack 34 is arranged along the direction of the second axis X and is in meshing relationship with the meshing teeth 961. When the second adjusting member 96 rotates, the torque about the first axis Z can be applied to the carrier plate 32 through the meshing relationship with the rack 34, so as to make the carrier plate 32 generate angular displacement about the first axis Z, and the central axis of the angular displacement is substantially coincident with the axis of the second adjusting member 96.

[0061] Further, in the embodiments, the second adjusting member 96 is sleeved on the outer periphery of the head portion 941 of the first adjusting member 94 and abuts against the surface of the carrier plate 32, and when the first adjusting member 94 generates displacement along the first axis Z, the second adjusting member 96 is displaced accordingly. Specifically, the second adjusting member 96 is provided with a countersunk hole (not marked in the figure), and the carrier plate 32 is provided with a connecting through hole coaxially communicated with the countersunk hole, the hole diameter of the connecting through hole is smaller than the hole diameter of the second adjusting member 96, the head portion 941 of the first adjusting member 94 is overlapped in the countersunk hole, and the screw portion 943 is arranged in the connecting through hole, and the second adjusting member 96 can be overlapped on the carrier plate 92 to realize indirect abutment between the head portion 941 of the first adjusting member 94 and the carrier plate 32. The hole diameter of the countersunk hole is larger than the hole diameter of the head portion 941, and the two are in clearance fit, so that the rotational movement of the first adjusting member 94 will not drive the second adjusting member 96 to rotate, and therefore the rotational movements of the first adjusting member 94 and the second adjusting member 96 will not interfere with each other.

[0062] In the embodiments, the rotational movement of the second adjusting member 96 is formed by the driving of the adjusting rod 92, and the connection relationship between the adjusting rod 92 and the second adjusting member 96 is a detachable transmission connection relationship. The transmission connection relationship between the adjusting rod 92 and the second adjusting member 96 can be realized by hole shaft cooperation or other mechanical connection relationships (for example, clamping cooperation). Please refer to FIG. 1 againFigure 4 , specifically in Figure 4 In the embodiment shown in the drawings, the adjustment rod 92 and the second adjustment member 96 are drivingly connected through a hole-shaft cooperation. The second adjustment member 96 is provided with a second non-circular hole 963, and the end of the adjustment rod 92 is provided with a second non-circular column 9203, the cross-sectional profile of which is matched with the cross-sectional profile of the second non-circular hole 963. The second non-circular column 9203 is detachably accommodated in the second non-circular hole 963, and is used to push the hole wall of the second non-circular hole 963 when rotating to drive the second adjustment member 96 to rotate. Specifically, the second non-circular hole 963 is arranged on the side of the second adjustment member 96 away from the bearing plate 32, and is in communication with the counter-bore through hole. The second non-circular hole 963 can also be in communication with the first non-circular hole 9411, so as to facilitate the adjustment rod 92 to be embedded in the first non-circular hole 9411 and the second non-circular hole 963 at one time. In the embodiment, the second non-circular hole 963 is a polygonal hole (for example, a hexagonal hole, etc.), and the second non-circular column 9203 is a polygonal prism (for example, a hexagonal prism, etc.). In other embodiments, the second non-circular hole 963 can be an elliptical hole or other irregular hole, and the second non-circular column 9203 can be an elliptical column or other irregular column, as long as the adjustment rod 92 can drive the second adjustment member 96 to rotate. When the user needs to adjust the rotation angle of the bearing plate 32 about the first axis Z, the adjustment rod 92 only needs to be rotated to drive the second adjustment member 96 to rotate. When the bearing plate 32 does not need to be adjusted, the second non-circular column 9203 is withdrawn from the second non-circular hole 963, so that the adjustment rod 92 and the second adjustment member 96 are separated, which can avoid the unintended displacement of the bearing plate 32 caused by the accidental touch of the adjustment rod 92, and the operation is convenient and reliable.

[0063] In the embodiment, the cooperation process of the detachable connection between the adjustment rod 92 and the first adjustment member 94 and the second adjustment member 96 is realized through the displacement of the adjustment rod 92 along the first axis Z. In order to ensure the connection reliability when the adjustment rod 92 and the first adjustment member 94 and the second adjustment member 96 are connected, and the positioning reliability when the adjustment rod 92 and the first adjustment member 94 and the second adjustment member 96 are separated, the position of the adjustment rod 92 in the embodiment is limited by the limiting mechanism 70. Specifically, please refer to Figure 3The positioning assembly 60 is arranged between the adjusting rod 92 and the limiting mechanism 70, and includes a positioning portion 62 and a cooperating portion 64, one of which is arranged on the adjusting rod 92 and the other of which is arranged on the limiting mechanism 70. The positioning portion 62 is in plurality, and the plurality of positioning portions 62 are arranged along the first axis Z in sequence. The cooperating portion 64 is in limiting cooperation with one of the positioning portions 62 to limit the installation position of the adjusting rod 92 relative to the limiting mechanism 70, so that the adjusting rod 92 is kept in transmission connection with the first adjusting member 94 and / or the second adjusting member 96. For example, one of the positioning portion 62 and the cooperating portion 64 is a protruding structure, and the other of which is a groove structure. The protruding structure is embedded in the groove structure, so as to limit the axial displacement of the adjusting rod 92 along the first axis Z. When the adjusting rod 92 moves along the first axis Z relative to the limiting mechanism 70, the cooperating portion 64 can be nested with different positioning portions 62.

[0064] In the embodiment, the positioning assembly 60 is formed by part of the structure of the limiting mechanism 70 and part of the structure of the adjusting rod 92. Please refer to Figure 3 and Figure 6 The limiting mechanism 70 is fixedly connected to the fixed seat 10, and includes a limiting seat 72 and an elastic positioning member 74. The limiting seat 72 is generally block-shaped, and is provided with an installation through hole 721, the hole axis of which is generally parallel to or coincides with the first axis Z. The adjusting rod 92 is arranged through the installation through hole 721, and the elastic positioning member 74 is arranged in the installation through hole 721 and elastically abuts between the adjusting rod 92 and the hole wall of the installation through hole 721. The above-mentioned positioning portion 62 is a groove (not marked in the figure) arranged around the outer periphery of the adjusting rod 92, and the elastic positioning member 74 has an elastic protrusion 741, which forms the above-mentioned cooperating portion 64 and is embedded in any one of the plurality of grooves, so as to limit the movement of the adjusting rod 92 relative to the limiting seat 72. Since the groove is an annular structure, the elastic protrusion 741 embedded in the groove can still keep the rotation freedom of the adjusting rod 92.

[0065] Please refer to Figure 7In the embodiment, the elastic positioning member 74 is a resilient plunger structure, which can include a plunger housing 743, an elastic member 745, and a clamping protrusion 747. The plunger housing 743 is generally columnar, and a blind hole 7431 is formed in the plunger housing 743. The clamping protrusion 747 is movably arranged at the opening of the blind hole 7431, and a part of the clamping protrusion 747 is accommodated in the blind hole 7431 and a part of the clamping protrusion 747 protrudes out of the blind hole 7431. The maximum outer diameter of the part of the clamping protrusion 747 located in the blind hole 7431 is greater than the diameter of the opening of the blind hole 7431, so that the clamping protrusion 747 is limited in the blind hole 7431 and cannot fall out. The elastic member 745 is arranged in the blind hole 7431, and the two ends of the elastic member 745 abut against the bottom wall of the blind hole 7431 and the clamping protrusion 747 respectively, so that the clamping protrusion 747 can keep the state of protruding out of the blind hole 7431. The elastic member 745 can be a coil spring, an elastic sleeve such as a rubber sleeve or a rubber column, etc. When the clamping protrusion 747 is pressed by an external force, the clamping protrusion 747 can retreat into the blind hole 7431 based on the compression deformation of the elastic member 745.

[0066] Further, please refer to Figure 3 and Figure 6 , the peripheral wall of the limiting seat 72 is provided with a radial through hole 723 extending along the radial direction of the limiting seat 72 and communicating with the mounting through hole 721, and the elastic positioning member 74 is mounted in the radial through hole 723, so that the clamping protrusion 747 protrudes into the mounting through hole 721. When the adjusting rod 92 is arranged in the mounting through hole 721 and the positioning part 62 is located in the mounting through hole 721, the clamping protrusion 747 is clamped with one of the positioning parts 62 (groove structure), and at this time, the adjusting rod 92 has a first relative position relationship with the limiting seat 72. When the adjusting rod 92 is subjected to an axial pressure or tension, the clamping protrusion 747 is pressed by the one of the positioning parts 62 (groove structure), and the clamping protrusion 747 retreats into the blind hole 7431. When the external force is removed and another positioning part 62 corresponds to the clamping protrusion 747, the clamping protrusion 747 protrudes again under the pushing of the elastic member 745 and is clamped with the another positioning part 62, and at this time, the adjusting rod 92 has a second relative position relationship with the limiting seat 72, so as to realize the adjustment and limiting of the different positions of the adjusting rod 92 on the first axis Z.

[0067] In the embodiment, the clamping protrusion 747 is a ball structure, and the clamping protrusion 747 and the elastic member 745 jointly constitute the structure of the elastic protrusion 741. In other embodiments, the elastic protrusion 741 can be realized by other structures, for example, it can be an elastic protrusion structure fixedly arranged on the hole wall of the mounting through hole 721, an elastic buckle structure, etc.

[0068] In the embodiment, the number of the elastic positioning members 74 is multiple, for example, two, three, four or more, which is not limited in the specification. The multiple elastic positioning members 74 are distributed at intervals around the outer periphery of the adjusting rod 92 and are all in clamping cooperation with the positioning portions 62 on the adjusting rod 92, thereby providing more uniform and stable clamping force, making the limiting and positioning of the adjusting rod 92 more reliable.

[0069] In the embodiment, the adjusting rod 92 is detachably connected with the first adjusting member 94 and the second adjusting member 96 through movement along the first axis Z and the positioning and limiting of the positioning assembly 60. For example, when the cooperating portion 64 is in clamping cooperation with one of the positioning portions 62, the adjusting rod 92 is in transmission connection with the first adjusting member 94; when the cooperating portion 64 is in clamping cooperation with the other of the positioning portions 62, the adjusting rod 92 is separated from the first adjusting member 94. For another example, when the cooperating portion 64 is in clamping cooperation with one of the positioning portions 62, the adjusting rod 92 is in transmission connection with the second adjusting member 96; when the cooperating portion 64 is in clamping cooperation with the other of the positioning portions 62, the adjusting rod 92 is separated from the second adjusting member 96.

[0070] The specification provides two specific examples of the adjusting mechanism 90, so that the adjusting rod 92 realizes detachable connection with the first adjusting member 94 and the second adjusting member 96 based on different structures or components, which will be described in detail below.

[0071] First Example

[0072] Please also refer to Figure 3 , Figure 4 and Figure 5 , as the first example provided by the present application, the adjusting mechanism 90 has part or all of the features or a combination of multiple features in the above-mentioned embodiments (without conflict), which will not be repeated here. Further, in the first example, the first non-cylinder 9201 and the second non-cylinder 9203 of the adjusting rod 92 are arranged at the same end of the adjusting rod 92, and when the adjusting rod 92 translates along the first axis Z, the first non-cylinder 9201 and the second non-cylinder 9203 are driven to move synchronously, and the synchronous connection or separation with the first adjusting member 94 and the second adjusting member 96 is realized. Correspondingly, the adjusting rod 92 has two positioned target positions in the direction of the first axis Z, at one of the target positions, the adjusting rod 92 is in transmission connection with the first adjusting member 94 and the second adjusting member 96, and at the other target position, the adjusting rod 92 is separated from the first adjusting member 94 and the second adjusting member 96.

[0073] Specifically, in the first example, the positioning part 62 is provided with two, two positioning parts including a first positioning part 621 and a second positioning part 623, the first positioning part 621 and the second positioning part 623 are arranged side by side along the first direction Z, and the second positioning part 623 is relatively closer to the first adjusting part 94. In the state that the first positioning part 621 is limited and matched with the matching part 64, the adjusting rod 92 is kept in transmission connection with the first adjusting part 94 and the second adjusting part 96 at the same time, which is specifically manifested as: the first non-cylindrical 9201 of the adjusting rod 92 is embedded in the first non-circular hole 9411, and the second non-cylindrical 9203 is embedded in the second non-circular hole 963. In the state that the second positioning part 963 is limited and matched with the matching part 64, the adjusting rod 92 is separated from the first adjusting part 94 and the second adjusting part 96, which is specifically manifested as: the first non-cylindrical 9201 of the adjusting rod 92 is located outside the first non-circular hole 9411, and the second non-cylindrical 9203 is located outside the second non-circular hole 963.

[0074] Further, in the first example, the limiting mechanism 70 is arranged on the side of the bearing seat 30 away from the fixed seat 10 and is arranged in a spaced manner with the bearing seat 30. The adjusting rod 92 includes a first rod 921 and a second rod 923, the second rod 923 is movably arranged in the limiting seat 72 of the limiting mechanism 70 and is detachably connected with the second adjusting part 96, wherein the second non-cylindrical 9203 is arranged at one end of the second rod 923. The first rod 921 is rotatably arranged in the second rod 923 and is detachably connected with the first adjusting part 94, wherein the first non-cylindrical 9201 is arranged at one end of the first rod 921. A first bearing 925 is arranged between the first rod 921 and the second rod 923, through which the first rod 921 and the second rod 923 can rotate relative to each other, and the rotating movements of the two are not affected by each other, so that the user can drive the first adjusting part 94 to move by rotating the first rod 921 alone, and drive the second adjusting part 96 to move by rotating the second rod 923 alone.

[0075] Specifically, the first rod 921 can include a first rotating part 9211 and a first rod part 9213, which are arranged side by side along the first axis Z. The first rotating part 9211 is connected to one end of the first rod part 9213, and the first non-cylindrical 9201 is arranged at the other end of the first rod 921. The outer diameter of the first rotating part 9211 is larger than that of the first rod part 9213, and the first rotating part 9211 is used for the part for the user's hand to operate. The first rotating part 9211 with a relatively large outer diameter can provide a relatively large torque, which is more labor-saving when the user rotates the first rotating part 9211.

[0076] The second rod member 923 can include a second rotating portion 9231 and a second rod portion 9233, which are parallel along the first axis Z. The second rotating portion 9231 is connected to one end of the second rod portion 9233, and the second non-circular cylinder 9203 is arranged at the other end of the second rod member 923. The outer diameter of the second rotating portion 9231 is greater than that of the second rod portion 9233, and the second rotating portion 9231 is used for the part for the user to operate. The second rotating portion 9231 with a relatively large outer diameter can provide a relatively large torque, and it is more labor-saving when the user rotates the second rotating portion 9231.

[0077] Further, the second rod member 923 is provided with a central through hole (not marked in the figure), the first rod portion 9213 is rotatably arranged in the central through hole and protrudes out of the central through hole towards one end of the first adjusting member 94, and the first non-circular cylinder 9411 is arranged at the end of the first rod portion 9213 protruding out of the central through hole, so as to be in transmission connection with the first adjusting member 94. The first bearing 925 is sleeved outside the first rod portion 9233 and located in the central through hole, so as to support the first rod portion 9213. The second rod portion 9213 is arranged in the mounting through hole 721 of the limiting seat 72, and the outer periphery of the second rod portion 9213 is provided with the first positioning portion 621 and the second positioning portion 623.

[0078] Therefore, in the first example, the adjusting rod 92 is of a split structure. When the first positioning portion 621 and the cooperating portion 64 are in clamping cooperation, the adjusting rod 92 is in transmission connection with the first adjusting member 94 and the second adjusting member 96. When the first rod member 921 of the adjusting rod 92 rotates, the first adjusting member 94 is driven to move along the first axis Z, so as to allow the first end 321 of the bearing plate 32 to move along the first axis Z, and the bearing plate 32 as a whole rotates about the second axis X; when the second rod member 923 of the adjusting rod 92 rotates, the second adjusting member 96 is driven to rotate, so as to exert a torque on the bearing plate 32 about the first axis Z through the rack 34, and the bearing plate 32 as a whole rotates about the first axis Z. It can be seen that only through the rotating movement of the adjusting rod 92 itself, the adjustment of two rotating degrees of freedom of the bearing seat 30 in the three-dimensional space can be realized, without the need to use multiple distributed adjusting members and other structures to realize the adjustment of multiple degrees of freedom. The space position occupied by the adjusting mechanism 90 provided in the embodiment is relatively small, and the user operation is relatively convenient.

[0079] In the first example, when the bearing plate 32 does not need to be adjusted, the second rod member 923 can be axially displaced, so that the first positioning portion 621 and the cooperating portion 64 are out of clamping cooperation, for example, the second positioning portion 623 and the cooperating portion 64 are in clamping cooperation. At this time, the adjusting rod 92 is separated from the first adjusting member 94 and the second adjusting member 96, so as to avoid the bearing plate 32 from being driven to produce unintended displacement due to the accidental touch of the adjusting rod 92, which is convenient and reliable to operate.

[0080] Second Example

[0081] Please refer to Figure 8 and Figure 9 As a second example provided in the present application, the adjustment mechanism 90 has part or all of the features or a combination of multiple features in the above-mentioned embodiments (without conflict), which will not be repeated here.

[0082] Further, in the second example, the first non-cylinder 9201 and the second non-cylinder 9203 of the adjustment rod 92 are arranged at the same end of the adjustment rod 92, and when the adjustment rod 92 translates along the first axis Z, the first non-cylinder 9201 and the second non-cylinder 9203 are moved. The adjustment rod 92 has three positioned target positions in the direction of the first axis Z, at one of the target positions, the adjustment rod 92 is in transmission connection with the first adjustment member 94 and is separated from the second adjustment member 96, at another target position, the adjustment rod 92 is separated from the first adjustment member 94 and is in transmission connection with the second adjustment member 96, and at another target position, the adjustment rod 92 is separated from both the first adjustment member 94 and the second adjustment member 96.

[0083] Specifically, in the second example, the positioning part 62 is provided with three positioning parts arranged in sequence along the first direction Z. The three positioning parts include a third positioning part 625, a fourth positioning part 627, and a fifth positioning part 629, the fifth positioning part 629 is located between the third positioning part 625 and the fourth positioning part 627, and the fourth positioning part 627 is located on the side of the fifth positioning part 629 towards the bearing seat 30. When the third positioning part 625 is in limiting cooperation with the cooperation part 64, the adjustment rod 92 is in transmission connection with the first adjustment member 94 and is separated from the second adjustment member 96, which is specifically manifested as: the first non-cylinder 9201 of the adjustment rod 92 is embedded in the first non-circular hole 9411, and the second non-cylinder 9203 is located outside the second non-circular hole 963; when the fourth positioning part 627 is in limiting cooperation with the cooperation part 64, the adjustment rod 92 is separated from the first adjustment member 94 and is in transmission connection with the second adjustment member 96, which is specifically manifested as: the first non-cylinder 9201 of the adjustment rod 92 is located outside the first non-circular hole 9411, and the second non-cylinder 9203 is embedded in the second non-circular hole 963; when the fifth positioning part 629 is in limiting cooperation with the cooperation part 64, the adjustment rod 92 is separated from the second adjustment member 94 and is separated from the first adjustment member 94, which is specifically manifested as: the first non-cylinder 9201 of the adjustment rod 92 is located outside the first non-circular hole 9411, and the second non-cylinder 9203 is located outside the second non-circular hole 963.

[0084] Further, in the second example, the first adjusting member 94 is arranged in the bearing seat 30 and connected to the fixed seat 10, the limiting mechanism 70 is fixedly connected to the fixed seat 10 and arranged on the side of the bearing seat 30 away from the fixed seat 10 and spaced apart from the bearing seat 30. The adjusting rod 92 is arranged in the limiting mechanism 70 and detachably connected to the first adjusting member 94.

[0085] Different from the split structure of the adjusting rod 92 in the first example, the adjusting rod 92 in the second example is a one-piece structure, which includes a third rotating part 9251 and a third rod part 9253, the third rotating part 9251 and the third rod part 9253 are parallel along the first axis Z. The third rotating part 9251 is connected to one end of the third rod part 9253, and the second non-cylindrical part 9203 is arranged at the other end of the third rod part 9253. The outer diameter of the third rotating part 9251 is larger than that of the third rod part 9253, and the third rotating part 9251 is used for the part for the user to operate, and the third rotating part 9251 with a larger outer diameter can provide a relatively larger torque, and it is more labor-saving when the user rotates the third rotating part 9251. The third rod part 9253 is provided with the third positioning part 625, the fourth positioning part 627 and the fifth positioning part 629. The third rod part 9253 is arranged in the mounting through hole 721 of the limiting seat 72, and the third positioning part 625, the fourth positioning part 627 and the fifth positioning part 629 are located in the mounting through hole 721.

[0086] Different from the above-provided embodiments, in the second example, the second adjusting member 96 is not sleeved on the outer periphery of the first adjusting member 94, but is rotatably arranged in the limiting mechanism 70. A second bearing 927 is arranged between the second adjusting member 96 and the limiting mechanism 70, and the adjusting rod 92 is rotatably arranged in the limiting mechanism 70 and the second adjusting member 96, and the adjusting rod 92 can be connected or separated from the second adjusting member 96 when moving along the first axis Z.

[0087] In the second example, the limiting mechanism 70 has some or all of the features or a combination of multiple features of the limiting mechanism 70 in the above embodiments (without conflict), which will not be described here. Further, in the second example, the limiting seat 72 of the limiting mechanism 70 is further provided with a receiving hole 725 on the side facing the bearing plate 32, the receiving hole 725 is coaxial and communicated with the mounting through hole 721, and the second bearing 927 is arranged in the receiving hole 725. The second adjusting member 96 is a gear structure, and the gear shaft part thereof is embedded in the bearing hole of the second bearing 927, so as to be supported and rotatable relative to the limiting seat 72. In this case, the second adjusting member 96 is arranged in relative spacing with the first adjusting member 94, and the head part 941 of the first adjusting member 94 can abut against the bearing plate 32 without the aid of the second adjusting member 96. The third rod part 9253 of the adjusting rod 92 is arranged in the mounting through hole 721 and the second adjusting member 96 and extends to be close to the first adjusting member 94.

[0088] The first non-cylinder 9201 and the second non-cylinder 9203 of the adjusting rod 92 are arranged at one end of the third rod portion 9253 away from the third rotating portion 9251 and on the side of the second adjusting member 96 facing the first adjusting member 94. When the adjusting rod 92 is translated along the first axis Z, the first non-cylinder 9201 and the second non-cylinder 9203 are synchronously moved to make the adjusting rod 92 in driving connection with the first adjusting member 94 or in driving connection with the second adjusting member 96.

[0089] Therefore, in the second example, the adjusting rod 92 is of an integrated structure. When the third positioning portion 625 and the cooperating portion 64 are in clamping cooperation, the adjusting rod 92 is in driving connection with the first adjusting member 94 and is separated from the second adjusting member 96, and the adjusting rod 92 is rotated to drive the first adjusting member 94 to move along the first axis Z, thereby allowing the first end 321 of the bearing plate 32 to move along the first axis Z and the bearing plate 32 to have a rotational movement about the second axis X as a whole. When the fourth positioning portion 627 and the cooperating portion 64 are in clamping cooperation, the adjusting rod 92 is separated from the first adjusting member 94 and is in driving connection with the second adjusting member 96, and the adjusting rod 92 is rotated to drive the second adjusting member 96 to rotate, thereby exerting a torque on the first end 321 of the bearing plate 32 about the first axis Z through the rack 34, and the bearing plate 32 has a rotational movement about the first axis Z as a whole. It can be seen that only the rotational movement of the adjusting rod 92 itself can realize the adjustment of two rotational degrees of freedom of the bearing seat 30 in the three-dimensional space, without the need of using multiple adjusting members distributed at multiple positions to realize the adjustment of multiple degrees of freedom. The space position occupied by the adjusting mechanism 90 provided in the embodiment is relatively small, and the user operation is relatively convenient.

[0090] When the fifth positioning portion 629 and the cooperating portion 64 are in clamping cooperation, the adjusting rod 92 is separated from the first adjusting member 94 and the second adjusting member 96, and the first non-cylinder 9201 and the second non-cylinder 9203 are located in the space between the first adjusting member 94 and the second adjusting member 96. In the second example, when the bearing plate 32 does not need to be adjusted, the adjusting rod 92 can be axially displaced to make the cooperating portion 64 and the third positioning portion 625 and the fourth positioning portion 627 all release the clamping cooperation, for example, to make the fifth positioning portion 629 and the cooperating portion 64 in clamping cooperation, at this time, the adjusting rod 92 is separated from the first adjusting member 94 and the second adjusting member 96, and the first non-cylinder 9201 and the second non-cylinder 9203 are located in the space between the first adjusting member 94 and the second adjusting member 96, which can avoid the non-expected displacement of the bearing plate 32 caused by the accidental touch of the adjusting rod 92, and the operation is convenient and reliable.

[0091] In summary, the mounting device 100 provided by the embodiment of the present application, the adjusting rod 92 of the adjusting mechanism 90 has the freedom of movement along the first axis Z and the freedom of rotation around the first axis Z relative to the limiting mechanism 70. When the adjusting rod 92 is connected with the first adjusting member 94, the rotating movement of the adjusting rod 92 drives the first adjusting member 94 to move along the first axis Z, so that the carrier 30 generates the rotating movement around the second axis X under the transmission of the linkage 30. Therefore, when it is necessary to adjust the spatial angle of the projector 200 relative to the second axis X, the user only needs to rotate the adjusting rod 92. The user can realize the adjustment of the two degrees of freedom of the projector 200 in the three-dimensional space through one adjusting mechanism 90, and therefore the space occupied by the adjusting mechanism 90 is relatively small, and the user operation is relatively convenient.

[0092] In addition, since the adjusting rod 92 is detachably connected with the first adjusting member 94 and the second adjusting member 96 respectively, when the adjusting rod 92 is connected with the first adjusting member 94 and the second adjusting member 96, the transmission connection relationship between the adjusting rod 92 and the carrier 30 can be established, so that the adjusting function of the mounting device 100 (as described above) can be conveniently realized. When the adjusting rod 92 is separated from the first adjusting member 94 and / or the second adjusting member 96, the transmission connection relationship between the adjusting rod 92 and the carrier 30 in at least one of the two degrees of freedom can be cut off, so that the spatial position change of the carrier 30 caused by the accidental touch of the adjusting rod 92 can be avoided, and the positioning after the adjustment is more reliable.
