Here, the target plane may be a side where the wall is located, or may be a side of the cabinet facing the wall and parallel to the wall. For example, when the target plane is a plane where a wall is located, the supporting platform 000 may be fixed on the wall by the supporting frame 100; when the target plane is a side of the cabinet facing the wall and parallel to the wall, the supporting platform 000 may be placed on the cabinet and may be fixed on the cabinet by the supporting frame 100.

The carrier 200 of the supporting platform 000 can be slidably connected to the supporting frame 100, and the carrier 200 has a carrying surface 200a. Here, the carrying surface 200a is used for carrying a laser projection host. For example, the carrier 200 can slide relative to the support 100 in a direction perpendicular to the target plane. Thus, the distance between the laser projection host and the target plane can be conveniently adjusted by sliding the bearing table 200 on the support frame 100. It should be noted that, when the target plane is the side where the wall is located, or the side of the cabinet facing the wall and parallel to the wall, the projection screen may be hung on the wall. Thus, through the sliding of the bearing table 200 on the support frame 100, the vertical distance between the laser projection host and the projection screen can be conveniently adjusted, so that the laser projection host can be adapted to the corresponding projection ratio, and the size of the picture projected by the laser projection host can be matched with the size of the projection screen.

To more clearly see the structure of the support platform 000, please refer to fig. 2, which is an exploded view of the support platform shown in fig. 1. The support platform 000 may further include: a first drive assembly 300 and a second drive assembly 400.

The first driving assembly 300 in the support platform 000 may include: the first driving motor 301 is fixed on the supporting frame 100, and the transmission structure 302 is connected with the first driving motor 301, and the transmission structure 302 is respectively connected with the supporting frame 100 and the bearing table 200. The first drive motor 301 may be configured to: the transmission structure 302 drives the carrier 200 to slide on the supporting frame 100 along a direction perpendicular to the target plane fixed by the supporting frame 100.

Here, under the drive of the first driving assembly 300, the plummer 200 can automatically slide on the support frame 100 along the direction perpendicular to the target plane, so that, when the laser projection host computer is borne by the plummer 200, the position of the laser projection host computer can be conveniently adjusted in the direction perpendicular to the target plane, and then the laser projection host computer can be adapted to the corresponding transmittance, so that the size of the projection picture projected by the laser projection host computer can be matched with the size of the projection screen fixed on the wall. Moreover, when different types of laser projection hosts are carried by the carrying platform 200, the carrying platform 200 can be controlled to slide on the supporting frame 100 by different distances through the first driving assembly 300, so as to ensure that the various types of laser projection hosts can adapt to respective transmittance, and further ensure that the projection images projected by the laser projection hosts have good effects.

The second driving assembly 400 may include: a second driving motor 401 fixed on the carrying platform 200, and a connecting rod 402 connected to the second driving motor 401, the connecting rod 402 is used for connecting to a side of the laser projection host close to the carrying surface 200a of the carrying platform 200, the second driving motor 401 is configured to: the connecting rod 402 is driven to move in a direction perpendicular to the carrying surface 200a.

Here, since the connecting rod 402 is connected to a side of the laser projection host close to the carrying surface 200a, when the second driving motor 401 in the second driving assembly 400 drives the connecting rod 402 to move in a direction perpendicular to the carrying surface 200a, the connecting rod 402 drives the laser projection host to move in a direction perpendicular to the carrying surface 200a. Thus, under the driving of the second driving assembly 400, the laser projection host carried by the carrying platform 200 can automatically move in the direction perpendicular to the carrying surface 200a, so that the position of the laser projection host can be conveniently adjusted in the gravity direction, the picture projected by the laser projection host can be matched with the projection screen fixed on the wall more easily, and the display effect of the projection picture projected by the laser projection host can be further improved.

To sum up, the application provides a supporting platform, includes: support frame, plummer, first drive assembly and second drive assembly. A support frame in the support platform is used for being fixed on a target plane, and the bearing platform is used for bearing the laser projection host. Under the drive of first drive assembly, the plummer can slide along the direction of perpendicular to target plane automatically on the support frame, so, can be comparatively convenient realize adjusting the position of laser projection host computer in the direction of perpendicular to target plane, and then can let the corresponding transmittance of laser projection host computer adaptation for the size of the projection picture that the laser projection host computer throws can be with the size phase-match of the projection screen of fixed on the target plane. And when the bearing platform bears different types of laser projection hosts, the bearing platform can be controlled to slide on the support frame by different distances through the first driving assembly, so that the various types of laser projection hosts can be matched with respective transmittance, and the effect of projection pictures projected by the laser projection hosts is better. Meanwhile, the bearing table can be controlled to move in the direction perpendicular to the bearing surface through the second driving assembly, so that the position of the laser projection host can be conveniently adjusted in the gravity direction, a picture projected by the laser projection host can be matched with a projection screen fixed on a wall more easily, and the display effect of the projection picture projected by the laser projection host can be further improved.

In the embodiment of the present application, please refer to fig. 3 and fig. 4, fig. 3 is a schematic view of a matching structure of a carrier and a second driving assembly provided in the embodiment of the present application, and fig. 4 is an exploded view of the structure shown in fig. 3 located on the other side. The carrier 200 may further have a through hole 200b. The through hole 200b has two opposite opening surfaces, one opening surface of the through hole 200b may be located on the supporting surface 200a, and the other opening surface is located on the back surface 200c of the carrier 200, where the back surface 200c of the carrier 200 is the surface opposite to the supporting surface 200a of the carrier 200.

The second driving motor 401 in the second driving assembly 400 is fixed in the rear surface 200c of the susceptor 200 at a position close to the through hole 200b. Thus, after the second driving motor 401 is fixed on the back surface 200c of the plummer 200, the second driving motor 401 does not leak outside the supporting platform 000, and the aesthetic property of the supporting platform 000 can be effectively improved. Illustratively, the carrier table 200 further has a first fastening hole D1, the second driving motor 401 has a second fastening hole D2 communicating with the first fastening hole D1, and a fastening member such as a bolt may be sequentially inserted through the first fastening hole D1 and the second fastening hole D2 to fix the second driving motor 401 to the carrier table 200.

After the second driving motor 401 is fixed on the bearing platform 200, a portion of the connecting rod 402 in the second driving assembly 400 may pass through the through hole O to be connected with the second driving motor 401, and another portion protrudes out of the bearing surface 200a. When the supporting surface 200a of the supporting table 200 supports the laser projection host, the portion of the connecting rod 402 protruding out of the supporting surface 200a may be connected to a side of the laser projection host close to the supporting surface 200a. Illustratively, the portion of the connecting rod 402 protruding from the bearing surface 200a is externally threaded. The side of the laser projection host close to the bearing surface 200a is provided with a threaded hole matched with the external thread. Thus, the portion of the connecting rod 402 protruding from the supporting surface 200a can be screwed to the side of the laser projection host close to the supporting surface 200a.

In the embodiment of the present application, please refer to fig. 5, and fig. 5 is a schematic structural diagram of a second driving assembly provided in the embodiment of the present application. In the second driving assembly 400, a portion of the connecting rod 402 passing through the through hole 200b may be fixedly connected with an output shaft 401a of the second driving motor 401. Here, the length direction of the output shaft 401a of the second driving motor 401 may be parallel to the length direction of the connecting rod 402.

In this case, the second driving motor 401 may be a telescopic motor, and an output shaft 401a of the second driving motor 401 can be telescopic in a direction perpendicular to the carrying surface 200a of the carrying table 200. In this way, when the portion of the connecting rod 402 passing through the through hole 200b is fixedly connected to the output shaft 401a of the second driving motor 401, the connecting rod 402 can be driven by the output shaft 401a of the second driving motor 401 to move in the direction perpendicular to the carrying surface 200a, so that the laser projection host connected to the connecting rod 402 can also move in the direction perpendicular to the carrying surface 200a.

Illustratively, a portion of the connecting rod 402 passing through the through hole 200b has a recessed structure, and at least a portion of the output shaft 401a of the second driving motor 401 may be located in this recessed structure. In this way, it is possible to ensure that the connecting rod 402 can be more stably connected to the output shaft 401a of the second drive motor 401. Here, there are various ways of fixedly connecting the portion of the connecting rod 402 passing through the through hole 200b with the output shaft 401a of the second driving motor 401, and the present application will be described by taking the following two implementation manners as examples:

first, glue (e.g., methyl cyanoacrylate) may be provided within the recessed features of the connecting bar 402; thereafter, at least a portion of the output shaft 401a of the second drive motor 401 may be placed in this recessed structure and a certain pressing force may be applied. After the glue in the recessed structure is cured, the connecting rod 402 and the output shaft 401a of the second driving motor 401 are fixedly connected together.

In a second implementation, as shown in fig. 5, a screw hole A1 may be provided on a side wall of the output shaft 401a of the second driving motor 401, and a connection through hole A2 communicating with the recess structure may be provided on a portion of the connection rod 402 passing through the through hole 200b. In this way, after at least a part of the output shaft 401a of the second driving motor 401 is placed in the recessed structure and the threaded hole A1 is communicated with the connecting through hole A2, the connecting rod 402 and the output shaft 401a of the second driving motor 401 can be fixedly connected together by a screw passing through the connecting through hole A2 and being in threaded connection with the threaded hole A1.

It should be noted that, before the connecting rod 402 and the output shaft 401a of the second driving motor 401, the connecting rod 402 needs to be screwed into a threaded hole provided in the laser projection host to ensure that the connecting rod 402 can be connected with the laser projection host. Thereafter, the connecting rod 402 may be passed through the through hole 200b of the carrier 200, and the connecting rod 402 may be fixedly coupled to the output shaft 401a of the second driving motor 401 through the through hole 200b.

In the embodiment of the present application, as shown in fig. 3 and fig. 4, one side of the laser projection host close to the supporting surface 200a of the supporting table 200 may have a plurality of threaded holes, that is, the number of the threaded holes may be multiple. The support platform 000 may include a plurality of second driving assemblies 400, a plurality of connecting rods 402 of the plurality of second driving assemblies 400 correspond to a plurality of threaded holes of the laser projection host one by one, and each connecting rod 402 is used for being in threaded connection with the corresponding threaded hole. For example, the carrier 200 in the support platform 000 may have a plurality of through holes 200b, when the laser projection host is placed on the carrier 200, the plurality of through holes 200b may be in one-to-one correspondence with the plurality of threaded holes, and the plurality of through holes 200b may also be in one-to-one correspondence with the plurality of second connecting rods 402 in the plurality of second driving assemblies 400. Thus, each second connecting rod 402 may be threaded through a corresponding through hole 200b to a corresponding threaded hole.

Wherein the plurality of second drive motors 401 in the plurality of second drive assemblies 400 are configured to: meanwhile, the connecting rods 402 are driven to move synchronously to adjust the distance between the laser projection host 200 and the carrying surface 200a, or the connecting rods 402 are driven to move asynchronously to adjust the light-emitting angle of the laser projection host 200. Therefore, the picture projected by the laser projection host can be matched with the projection screen fixed on the wall more easily.

In one possible implementation, the number of the second driving assemblies 400 in the supporting platform 000 is four, and four connecting rods 402 in the four second driving assemblies 400 may be respectively connected with four corners in the base of the laser projection host. Here, the base of the laser projection host may have a rectangular shape. Thus, when the distance between the laser projection host and the bearing surface 200a of the bearing table 200 needs to be adjusted, the four second driving motors 401 in the four second driving assemblies 400 need to drive the four connecting rods 402 to move synchronously, so that the laser projection host can move synchronously at each position along the direction perpendicular to the bearing surface 200a, and the distance between the laser projection host and the bearing surface 200a can be adjusted.

When the light-emitting angle of the laser projection host needs to be adjusted, the four second driving motors 401 in the four second driving assemblies 400 need to drive the four connecting rods 402 to move asynchronously, so that the distances of the laser projection host moving in the direction perpendicular to the bearing surface 200a at different positions are different, and the light-emitting angle of the laser projection host can be adjusted. For example, the pitch angle of the light emitting direction of the laser projection host may be adjusted by asynchronous movement of the four connecting rods 402. For example, two second driving motors 401 close to the wall among the four second driving motors 401 can simultaneously drive two corresponding connecting rods 402 to synchronously move, the other two second driving motors 401 can simultaneously drive two corresponding connecting rods 402 to synchronously move, and the distance that the two second driving motors 401 close to the wall drive the connecting rods 402 to move is different from the distance that the other two second driving motors 401 drive the connecting rods 402 to move, so that the pitch angle of the light emitting direction of the laser projection host can be adjusted.

It should be noted that, each connecting rod 402 in the present application needs to be screwed with the laser projection host. Therefore, during the asynchronous movement of the plurality of connecting rods 402, it is necessary to ensure that the moving distance difference between any two connecting rods 402 is less than or equal to 10 mm, so as to ensure that the plurality of connecting rods 402 will not damage the laser projection host during the asynchronous movement of the plurality of connecting rods 402.

In the embodiment of the present application, please refer to fig. 6, where fig. 6 is a schematic diagram of a transmission structure provided in the present application. The transmission structure 302 in the first driving assembly 300 may include: a lead screw 302a fixedly connected with an output shaft 301a of the first driving motor 301, and a nut 302b sleeved on the lead screw 302a, wherein the nut 302b may be fixedly connected with the plummer 200, and the length direction of the lead screw 302a may be perpendicular to the target plane.

Wherein the first drive motor 301 is configured to: the screw shaft 302a is rotated, so that the nut 302b moves on the screw shaft 302a in the longitudinal direction of the screw shaft 302 a. In this case, the nut 302b is fixedly connected to the carrier 200. Therefore, when the nut 302b moves on the lead screw 302a along the length direction of the lead screw 302a, the nut 302b can drive the plummer 200 fixedly connected with the nut to move along the length direction of the lead screw 302 a. And the length direction of the lead screw 302a is perpendicular to the target plane. Therefore, when the platform 200 moves along the length direction of the lead screw 302a, the platform 200 can be guaranteed to move on the supporting frame 100 along the direction perpendicular to the target plane.

In the embodiment of the present application, as shown in fig. 6, the transmission structure 302 in the first driving assembly 300 may further include: a guide rod 302c fixedly connected with the support frame 100, and a slide block 302d sleeved on the guide rod 302c and slidably connected with the guide rod 302 c. One side of the sliding block 302d is fixedly connected with the nut 302b, and the other side of the sliding block 302d is fixedly connected with the bearing table 200. Here, the guide bar 302c may have a length direction parallel to that of the lead screw 302a, and both perpendicular to the target plane. Therefore, when the nut 302b moves along the length direction of the lead screw 302a on the lead screw 302a, the nut 302b can drive the sliding block 302d to slide on the guiding rod 302c along the length direction of the guiding rod 302c, and then the sliding block 302d can drive the bearing table 200 to slide on the supporting frame 100 along the direction perpendicular to the target plane. Through the arrangement of the sliding block 302d and the guiding rod 302c, which are mutually matched, the bearing table 200 can slide on the supporting frame 100 more stably.

For example, as shown in fig. 6, the transmission structure 302 in the first driving assembly 300 may further include: the adaptor 302e. The adaptor 302e may be fixedly connected to the nut 302b, and the adaptor 302e may also be fixedly connected to the slider 302d. Thus, the sliding block 302d and the nut 302b can be fixedly connected together through the adaptor 302e.

In the present application, please refer to fig. 7, fig. 7 is a schematic view illustrating an assembly of a supporting frame and a first driving assembly according to an embodiment of the present application. The support stand 100 in the support platform 000 may include: the support frame comprises a support frame body 101 and a support box 102 fixedly connected with the support frame body 101. Here, the support frame body 101 is used to be fixedly connected with a target plane, the support box 102 has a receiving space 102a, and each part in the first driving assembly 300 can be located in the receiving space 102 a.

For example, the first driving motor 301 of the first driving assembly 300 may be fixed on the bottom surface of the accommodating space 102a through a motor support 303.

One end of a screw 302a in the transmission structure 302 in the first driving assembly 300 may be fixedly connected to an output shaft of the first driving motor 301, and the other end may be fixed to the bottom surface of the accommodating space 102a through a support frame 304, and the support frame 304 may support an end of the screw 302a away from the first driving motor 301, so as to ensure that the first driving motor 301 can stably drive the screw 302a to rotate.

The guiding rod 302c of the transmission structure 302 in the first driving assembly 300 may be located in the accommodating space 102a, and two ends of the guiding rod 302c may be respectively and fixedly connected to two inner side surfaces of the accommodating space 102a, which are oppositely disposed.

Optionally, in order to ensure that the plummer 200 can slide on the supporting frame 100 more stably, two guiding rods 302c may be disposed in the transmission structure 302, for example, the two guiding rods 302c are disposed at two sides of the supporting box 102 in the supporting frame 100, and a plurality of sliders 302d may be sleeved on each guiding rod 302c (the application is described by taking two sliders 302d sleeved on the guiding rod 302c as an example). Like this, the slider 302d that cup joints on two guide bars 302c can respectively with the both sides fixed connection of plummer 200 to guarantee that the both sides of plummer 200 all have the slider 302d that can drive its gliding, and then can guarantee that plummer 200 can be stable slide on support frame 100.

Here, the lead screw 302a in the transmission structure 302 needs to be distributed near one of the two guide rods 302c, and the adaptor 302c in the transmission structure 302 can respectively and fixedly connect two sliding blocks 302d sleeved on the guide rod 302c near the lead screw 302a, so as to ensure that the two sliding blocks 302d can synchronously slide on the guide rod 302c under the driving of the nut 302 b. It should be noted that the two sliding blocks 302d sleeved on the other guiding rod 302c of the two guiding rods 302c need not be fixedly connected together.

For the connection between the slider 302d and the carrier 200, in a possible implementation manner, a threaded hole may be provided on a side surface of the slider 302d, and an adapter through hole communicating with the threaded hole is provided on the carrier 200. In this way, the connection between the slider 302d and the carrier 200 can be realized by using a screw to pass through the through hole and to be in threaded connection with the threaded hole.

In the present application, the sum of the width of the decoration plate 500 and the maximum distance that the carrier 200 slides on the support frame 100 in the direction perpendicular to the target plane is less than or equal to the width of the support box 102. In this way, it can be ensured that the first driving assembly 400 carried in the accommodating space 102a of the supporting box 102 is not exposed from the supporting platform 000 in the process of sliding the bearing platform 200 on the supporting frame 100, and further, it can be ensured that the supporting platform 000 has good aesthetic property.

In this way, the control assembly 600 can respectively control the first driving motor 301 and the second driving motor 302 to perform position adjustment on the laser projection host carried by the carrying platform 200.

Referring to fig. 9, fig. 9 is a schematic structural diagram of a laser projection system according to an embodiment of the present disclosure. The laser projection system may include: the above embodiment shows the supporting platform 000, and the laser projection host 001 located on the supporting surface 200a of the supporting stage 200.

In an embodiment of the present application, the laser projection system may further include: a projection screen 002 fixed on the wall. In one possible implementation, a cabinet 003 may be provided beside the wall, and the support platform 000 may be placed on the cabinet 003. In this case, the support frame 100 in the support platform 000 may be fixed to a face of the cabinet 003 adjacent to and parallel to the wall.

In this application, as shown in fig. 10, fig. 10 is a schematic structural diagram of another laser projection system provided in this embodiment of the application, when the laser projection host 001 needs to project a picture, the first driving assembly 300 in the supporting platform 000 needs to control the carrying table to move in a direction away from the wall, so that the laser projection host 001 can move in the direction away from the wall, and the second driving assembly 400 in the supporting platform 000 can control the projection host 001 to move in a gravity direction, so as to ensure that a size of the picture projected by the laser projection host 001 can better match with a size of the projection screen 002.

In the present application, when the support platform 000 includes the control assembly 600 communicatively coupled to the first driving motor 301 and the second driving motor 401, respectively, the laser projection host 001 is communicatively coupled to the control assembly 600. For example, the laser projection host 001 and the control component 600 mounted on the support platform 000 may be communicatively connected via a Universal Serial Bus (USB).

In this way, when the position of the laser projection host 001 needs to be adjusted, the first driving motor 301 and the second driving motor 401 may be controlled to operate by sending a control instruction to the control assembly 600 through a mobile terminal (e.g., a remote controller or a mobile phone) in communication connection with the laser projection host 001, so as to move the plummer 200 in the supporting platform 000 to a desired position, and further move the laser projection host 001 to the desired position.

In this application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" means two or more unless explicitly defined otherwise.

The above description is intended only to illustrate the alternative embodiments of the present application, and should not be construed as limiting the present application, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present application should be included in the protection scope of the present application.
