[0025] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the technical solutions in the related art, the following will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0026] In the related art, for some movable projection devices, in order to facilitate the adjustment of the angle of the projection device, the projection device is generally mounted on the support through the mounting part on the support, so as to facilitate the adjustment of the angle of the projection device. If the mounting part is accidentally touched when the projection device is in an inclined state, the position of the projection device on the support may be offset or the projection device may slide off the support, etc.

[0027] In view of the above, in a first aspect, referring to Figures 1-3 , the present application provides a device support 1, which comprises a base 10, a swing assembly 20 and a locking assembly (not shown separately).

[0028] The swing assembly 20 is rotationally connected to the base 10, and the swing assembly 20 is provided with a bearing surface 231 for bearing a device; the locking assembly is arranged on the swing assembly 20, and the locking assembly comprises a locking part 41 and a self-locking part 42 (as Figure 6 shown), and the locking part 41 and the self-locking part 42 are both movably connected to the swing assembly 20.

[0029] The rotating track of the swing assembly 20 has a first position and a second position, and the self-locking piece 42 has a avoiding position and a limiting position. When the swing assembly 20 is at the first position, the supporting surface 231 is in a horizontal state, that is, the supporting surface 231 is parallel to the horizontal plane. When the supporting surface 231 is in the horizontal state, the self-locking piece 42 is at the avoiding position to avoid the moving track of the locking piece 41. At this time, the locking piece 41 can move relative to the swing assembly 20, so that the locking piece 41 can be locked and unlocked with the tray 23. When the supporting surface 231 is at the second position, the supporting surface 231 is in a non-horizontal state, that is, the supporting surface 231 is arranged at an angle with the horizontal plane. The self-locking piece 42 is at the limiting position to limit the moving track of the locking piece 41, so that the movement of the locking piece 41 is blocked, thereby blocking the movement of the locking piece 41 and unlocking the tray 23. The device can be a projector.

[0030] Specifically, the projector can be installed on the supporting surface 231. The swing assembly 20 can rotate relative to the base 10 to drive the projector on the supporting surface 231 to swing, so as to change the angle between the supporting surface 231 and the horizontal plane, realize the angle adjustment of the projector, and the locking piece 41 can be locked with the swing assembly 20, so as to fix the projector on the supporting surface 231 to the swing assembly 20, and ensure the stability of the projector. Figure 1 The swing assembly 20 in the first position, Figure 2 The swing assembly 20 in the second position. It can be understood that when the swing assembly 20 does not rotate relative to the base 10, the swing assembly 20 is at the first position. At this time, the supporting surface 231 is parallel to the horizontal plane, the self-locking piece 42 is at the avoiding position, and the locking piece 41 can move relative to the swing assembly 20, so that the locking piece 41 can be locked and unlocked with the swing assembly 20, thereby the projector on the supporting surface 231 can be quickly installed or disassembled. When the swing assembly 20 rotates relative to the base 10, the swing assembly 20 is at the second position. At this time, the supporting surface 231 is at an angle with the horizontal plane, and the self-locking piece 42 enters the limiting position to prevent the movement of the locking piece 41, so that the locking piece 41 and the swing assembly 20 form a self-locking state, thereby reducing the probability of the projector falling when the supporting surface 231 is in an inclined state.

[0031] It should be noted that in the embodiments of the present application, the locking piece 41 can be locked and unlocked with the swing assembly 20 in the horizontal state, so as to facilitate the detachable connection between the locking piece 41 and the swing assembly 20. When the supporting surface 231 is in the inclined state, if the locking piece 41 is accidentally touched, the swing assembly 20 is prone to position deviation or sliding with respect to the locking piece 41. In the embodiments, the locking piece 41 is locked with the swing assembly 20 in the inclined state, and the self-locking piece 42 enters the limiting position to prevent the locking piece 41 from moving, so that a firm self-locking is formed between the locking piece 41 and the swing assembly 20, the stability of the equipment on the supporting surface 231 in the inclined state is improved, the sliding of the equipment in the inclined state of the supporting surface 231 is effectively prevented, the damage risk caused by the accidental touch and the sliding of the equipment from the inclined supporting surface 231 is effectively reduced, and the safety and stability of the equipment support 1 are improved.

[0032] In some embodiments of the present application, as shown in Figures 1-2 The base 10 includes a seat body 11 and a load-bearing arm 12, the load-bearing arm 12 is rotationally connected with the seat body 11 around the vertical direction, and the swing assembly 20 is arranged on the load-bearing arm 12. Specifically, the seat body 11 can provide stable support for the equipment support 1 and the projector, and the load-bearing arm 12 can rotate along the vertical direction to adjust the projection direction of the projector on the swing assembly 20, thereby enhancing the use flexibility of the equipment support 1.

[0033] For example, a plurality of steel balls can be arranged between the load-bearing arm 12 and the seat body 11 to reduce the rotational friction therebetween and ensure smooth rotation of the load-bearing arm 12. In addition, a plurality of touch beads can be arranged on one of the load-bearing arm 12 and the seat body 11, and the other one of the load-bearing arm 12 and the seat body 11 is used to contact the touch beads. The plurality of touch beads are uniformly arranged in a circle around the vertical direction. When the load-bearing arm 12 rotates relative to the seat body 11, the touch beads can provide a damping feeling, which not only reduces the rotation of the load-bearing arm 12 due to accidental touch, but also provides a reference for the rotation angle of the load-bearing arm 12.

[0034] Please refer to Figures 3-5 In some embodiments of the present application, the swing assembly 20 includes a swing arm 21, a carrier 22 and a tray 23, the swing arm 21 is rotationally connected with the base 22, the carrier 22 and the tray 23 are arranged on the swing arm 21, and the supporting surface 231 is located on the tray 23; the locking assembly is movably connected with the carrier 22 and / or the tray 23.

[0035] Specifically, the external device is installed on the supporting surface 231 of the tray 23, the swing arm 21 is rotatably connected with the base 22 around the first axis line L1 extending in the horizontal direction, so that the orientation and height of the device on the tray 23 can be adjusted by rotating the swing arm 21. The locking assembly is movably connected with the carrier 22, or the locking assembly is movably connected with the tray 23, or the locking assembly is movably connected with both the carrier 22 and the tray 23, so that the carrier 22 and the tray 23 can be locked by the locking assembly, thereby making the connection among the tray 23, the carrier 22 and the locking assembly more stable, and improving the safety and stability of the device support 1.

[0036] Further, please refer to Figures 3-5 In some embodiments of the present application, the locking assembly 41 comprises a clamping portion 411 movably connected with the carrier 22, and the tray 23 has a first clamping groove 232, the clamping portion 411 is used to clamp and separate with the first clamping groove 232, so as to lock and unlock the carrier 22 and the tray 23.

[0037] When the swing assembly 20 is in the first position, the self-locking member 42 is in the avoiding position, the clamping portion 411 can slide relative to the carrier 22, and the clamping portion 411 can flexibly clamp and separate with the first clamping groove 232, thereby locking and unlocking the carrier 22 and the tray 23. For example, when the clamping portion 411 slides to separate from the first clamping groove 232, the tray 23 is not connected with the carrier 22, so the tray 23 can be easily detached from the carrier 22. When the swing assembly 20 is in the second position, the clamping portion 411 clamps with the first clamping groove 232, that is, the clamping portion 411 is fixed with the tray 23, and the clamping portion 411 can lock the carrier 22 and the tray 23 together, and the self-locking member 42 is in the limiting position, which limits the sliding of the clamping portion 411 relative to the carrier 22. It can be understood that when the supporting surface 231 is in a non-horizontal state, the clamping portion 411 clamps with the first clamping groove 232, and the movement of the clamping portion 411 is limited by the self-locking member 42, thereby forming self-locking between the locking assembly 41 and the tray 23, so as to reduce the probability of the projector falling when the supporting surface 231 is in an inclined state.

[0038] In some embodiments, as Figure 4As shown, the latching part 411 has a stepped structure. When the latching part 411 latches with the first latching slot 232, the stepped structure is inserted into the first latching slot 232 and latches and fixes with the inner wall of the first latching slot 232. There can be two latching parts 411, and the two latching parts 411 move in opposite directions. At the same time, the tray 23 has two first latching slots 232, and each first latching slot 232 corresponds to one latching part 411. When the two latching parts 411 move towards each other, the distance between the two latching parts 411 decreases. At this time, the stepped structures on the two latching parts 411 can be separated from the first latching slots 232, so that the carrier 22 is unlocked from the tray 23. When the two latching parts 411 move away from each other, the distance between the two latching parts 411 increases. At this time, the stepped structures on the two latching parts 411 can be inserted into the first latching slots 232, so that the carrier 22 is locked to the tray 23.

[0039] Furthermore, in some embodiments of this application, the locking assembly further includes a first elastic element 44, wherein the first elastic element 44 may be a spring, a sheet, or a spring tube, etc.

[0040] The first elastic element 44 can be disposed between the latching part 411 and the carrier 22. The first elastic element 44 is used to reset the latching part 411. It is easy to understand that when the latching part 411 is latched in the first slot 232, the first elastic element 44 is in a first deformation state. At this time, the first elastic force of the first elastic element 44 helps to ensure the latching stability between the latching part 411 and the first slot 232 and prevents the latching part 411 from accidentally slipping off. When the latching part 411 is separated from the first slot 232, the first elastic element 44 is in a second deformation state. At this time, the second elastic force of the first elastic element 44 helps to reset the latching part 411 and ensure that the latching part 411 can quickly and accurately return to the initial position for the next latching operation.

[0041] Alternatively, in some embodiments, such as Figure 6 As shown, the locking member 41 includes two oppositely arranged latching portions 411, which are slidably connected to the bearing member 22 in opposite directions. A first elastic member 44 is disposed between the two latching portions 411 and is used to reset the two latching portions 411.

[0042] It is easy to understand that when the two locking parts 411 slide towards each other, the two locking parts 411 together compress the first elastic member 44. At this time, the elastic force generated by the first elastic member 44 has a tendency to reset the locking parts 411, ensuring that the two locking parts 411 can quickly return to their initial positions after separation. When the two locking parts 411 slide backwards until both locking parts 411 are engaged with the first slot 232, the first elastic member 44 can also be in a compressed state. The elastic force generated by the first elastic member 44 helps to improve the locking stability and prevent the locking parts 411 from sliding accidentally.

[0043] Further, please refer to Figure 6 In some embodiments of the present application, the locking assembly further comprises a rotating member 43, the rotating member 43 is rotatably connected with the bearing member 22, and the rotating member 43 is provided with a limiting groove 431; the locking member 41 further comprises a linkage rod 412, the first end of the linkage rod 412 is connected with the clamping portion 411, and the second end of the linkage rod 412 is located in the limiting groove 431; the rotating member 43 rotates to drive the limiting groove 431 to slide relative to the linkage rod 412, and drive the linkage rod 412 and the clamping portion 411 to slide relative to the bearing member 22, so that the clamping portion 411 is locked or unlocked with the bearing member 22.

[0044] Specifically, the rotating member 43 rotates to change the position of the limiting groove 431, so that the position of the linkage rod 412 in the limiting groove 431 also changes; the limiting groove 431 can drive the linkage rod 412 to move, and the movement of the linkage rod 412 further drives the clamping portion 411 to slide, so as to realize the clamping and separation of the clamping portion 411 and the first clamping groove 232 on the tray 23. The limiting groove 431 can provide guiding and limiting effects for the linkage rod 412, so as to make the movement track of the linkage rod 412 more accurate and stable, and ensure the reliability of the clamping operation. The linkage rod 412 and the clamping portion 411 can be integrally formed, so as to improve the strength and stability of the overall structure of the locking member 41.

[0045] Further, please refer to Figure 6 In some embodiments of the present application, the rotating member 43 is provided with a protruding portion 433, and the bearing member 22 is provided with a plurality of matching grooves (not shown in the figure) for the protruding portion 433 to insert.

[0046] Specifically, in the process of rotating, the protruding portion 433 on the rotating member 43 rotates together with the rotating member 43, and the protruding portion 433 can be inserted into the matching grooves on the bearing member 22 in sequence, so as to provide damping feeling for the rotation of the rotating member 43; the arrangement of the protruding portion 433 and the matching grooves can not only realize accurate positioning of the rotating member 43, but also reduce accidental rotation of the rotating member 43 due to accidental touch, and improve the safety of operation. The protruding portion 433 can be a ball, which is beneficial to improve the rotation smoothness between the rotating member 43 and the bearing member 22.

[0047] In some embodiments of the present application, the locking assembly further comprises a second elastic member 45 (not shown in the figure), the second elastic member 45 is arranged between the rotating member 43 and the bearing member 22, and the second elastic member 45 is used for resetting the rotating member 43.

[0048] It can be understood that when the rotating member 43 is rotated by an external force, the second elastic member 45 is elastically deformed, the rotating member 43 drives the linkage rod 412 and the clamping portion 411 to move, at this time, the clamping portion 411 moves to a position where it can be separated from the first clamping groove 232, the restoring elastic force generated by the second elastic member 45 drives the rotating member 43 to rotate and return to the original position, ensuring that the clamping portion 411 moves to a position where it can be clamped with the first clamping groove 232, thereby improving the stability of the overall structure of the locking assembly and the smoothness of the operation.

[0049] Please refer to Figures 3-5 In some embodiments of the present application, the carrier 22 has a mounting cavity 221 and a first opening 222 communicating with the mounting cavity 221, the first opening 222 is arranged corresponding to the first clamping groove 232, the locking assembly is located in the mounting cavity 221, the clamping portion 411 passes through the first opening 222 and is clamped or separated from the first clamping groove 232.

[0050] Among them, the mounting cavity 221 can provide a setting basis and a protection space for the locking assembly, reduce the interference of the outside to the locking assembly, and ensure the stability of the clamping portion 411 and the tray 23. The clamping portion 411 passes through the first opening 222 on the carrier 22 and is clamped with the first clamping groove 232 on the tray 23, so that the carrier 22 and the tray 23 can be more stably connected together, ensuring the stability of the tray 23 during use.

[0051] Further, as Figure 6 shown, the carrier 22 also has a second opening 223 communicating with the mounting cavity 221, the locking assembly is located in the mounting cavity 221, and at least part of the rotating member 43 extends out of the mounting cavity 221 through the second opening 223.

[0052] It is easy to understand that a part of the rotating member 43 passes through the second opening 223, so as to facilitate the user to exert a driving force on the rotating member 43 to drive the rotation of the rotating member 43, thereby controlling the linkage rod 412 and the clamping portion 411. For example, the rotating member 43 can be provided with a push rod 44, the push rod 44 extends out of the mounting cavity 221 through the second opening 223, the user can easily rotate the rotating member 43 by pushing the push rod 44, thereby controlling the movement of the linkage rod 412 and the clamping portion 411, ensuring the convenience and efficiency of the clamping operation.

[0053] Please refer to Figures 6-7In some embodiments of the present application, the rotating member 43 is further provided with a sliding groove 432 extending in a first direction, the first direction being at an angle to the extension direction of the first axis line L1, the sliding groove 432 being in communication with the limiting groove 431; the self-locking member 42 is movably arranged in the sliding groove 432, and the self-locking member 42 can move in the sliding groove 432; when the bearing member 22 is located at the first position, the self-locking member 42 is located at the avoiding position to avoid the limiting groove 431 and the linkage rod 412, so that the limiting groove 431 can slide relative to the linkage rod 412; when the bearing member 22 is located at the second position, the self-locking member 42 is located at the limiting position to block the relative movement of the limiting groove 431 and the linkage rod 412.

[0054] Specifically, when the self-locking member 42 is located at the avoiding position, the self-locking member 42 is away from the communication position of the sliding groove 432 and the limiting groove 431, at this time, the self-locking member 42 can avoid the movement track of the linkage rod 412, that is, the limiting groove 431 can slide relative to the linkage rod 412, and the linkage rod 412 can enter the communication position of the limiting groove 431 and the sliding groove 432 via the limiting groove 431; when the self-locking member 42 is located at the limiting position, the self-locking member 42 is located at the communication position of the sliding groove 432 and the limiting groove 431, at this time, the self-locking member 42 will block the movement of the linkage rod 412, so that the rotating member 43 cannot be rotated, and the clamping portion 411 cannot be separated from the first clamping groove 232, thereby ensuring the stable connection of the bearing member 22 and the tray 23.

[0055] It should be noted that when the bearing member 22 is in the inclined state, the sliding groove 432 is also in the inclined state, at this time, the self-locking member 42 can automatically slide to the lower end position of the sliding groove 432 under the action of gravity, since the limiting groove 431 is in communication with the position close to the end of the sliding groove 432, so at this time, the self-locking member 42 is located at the communication position of the sliding groove 432 and the limiting groove 431, that is, when the bearing member 22 is inclined, the self-locking member 42 can automatically slide to the limiting position under the action of gravity. The present embodiment ingeniously utilizes the cooperation of the sliding groove 432 and the limiting groove 431 by arranging the self-locking member 42, and effectively controls the linkage rod 412 by simple position transformation of the self-locking member 42, thereby further enhancing the safety and reliability of the equipment support 1.

[0056] It should also be noted that when the carrier 22 is in the first position, there is no rotation between the swing arm 21 and the base 10, and the supporting surface 231 remains horizontal. At this time, the self-locking member 42 is in the avoidance position, and the linkage rod 412 can slide freely without being affected by the self-locking member 42, which further allows the locking part 411 to slide, thereby allowing the tray 23 and the carrier 22 to be fixed or disassembled. When the carrier 22 is in the second position, the swing arm 21 and the base 10 rotate, the supporting surface 231 tilts, and the sliding groove 432 is also tilted. Under the action of gravity, the self-locking member 42 slides to the lower end position of the sliding groove 432 (i.e., the limit position), thereby blocking the movement of the linkage rod 412 and preventing the locking part 411 from sliding and separating from the first locking groove 232, thus ensuring a stable connection between the carrier 22 and the tray 23 in the tilted state.

[0057] In some embodiments, such as Figures 6-7 As shown, the self-locking component 42 can be a ball bearing, allowing it to move flexibly within the sliding groove 432. This ensures that the self-locking component 42 can smoothly roll to the predetermined position (avoidance position and limit position) when the carrier 22 is in different positions. When the carrier 22 is in the first position, the ball bearing is located at the end of the sliding groove 432 away from the limit groove 431, thus avoiding the limit groove 431 and the linkage rod 412. At this time, the limit groove 431 can slide relative to the linkage rod 412. When the carrier 22 is in the second position, the ball bearing is located at the connection between the sliding groove 432 and the limit groove 431. The ball bearing can effectively lock the linkage rod 412 at the connection between the sliding groove 432 and the limit groove 431, thereby preventing the relative sliding between the limit groove 431 and the linkage rod 412. This also prevents the rotating component 43 from rotating, further improving the stability and safety of the overall structure and ensuring reliability during operation.

[0058] Secondly, embodiments of this application also provide a projection device, including a projector (not shown in the figure) and a device bracket 1 as described in any of the above embodiments, wherein the projector is mounted on the support surface 231 of the tray 23.

[0059] Specifically, the projector is connected to the support member 22 via the tray 23, which not only makes the projector easy to install and remove, but also improves the stability of the projector in a tilted state, enhances the safety and convenience of the projection device during use, and effectively reduces the risk of damage caused by the projector slipping off the support member 22 due to accidental touch.
