Suspended ceiling mounting frame

Abstract

The utility model is suitable for the technical field of equipment installation, and provides a suspended ceiling installation frame which comprises a fixing structure, an installation structure, a rotary connecting piece, a connecting rod and an electric push rod. The mounting structure is rotationally connected with the fixing structure. The electric push rod drives the mounting structure to rotate relative to the fixing structure, so that the mounting structure is switched between the folding configuration and the unfolding configuration. In the process that the fixing structure rotates relative to the mounting structure, the first end of the connecting rod rotates relative to the mounting structure, and the second end of the connecting rod rotates in the sliding groove of the fixing structure and can slide along the sliding groove. Compared with an existing complex multi-connecting-rod structure arranged between a mounting structure and a fixing structure, the connecting rods are simple in structure and movement mode, the requirements for machining precision and movement matching degree are lowered, the problem that the mounting structure is prone to shaking or blocking when rotating relative to the fixing structure is solved, and the service life of the connecting rods is prolonged. And therefore, the stability and smoothness of the operation of the suspended ceiling mounting frame are improved.

The ceiling mounting frame usually includes a driving mechanism and a rotatably connected fixed structure and mounting structure. The fixed structure is used to be fixed on the use location. A multi-link structure is connected between the fixed structure and the mounting structure. The driving mechanism is configured to drive the mounting structure to rotate relative to the fixed structure to achieve the unfolding or folding of the ceiling mounting frame. However, the current multi-link structure has many components and a complex structure. During the rotation of the mounting structure relative to the fixed structure, each component of the multi-link structure participates in the linkage, and the movement mode of the multi-link structure is relatively complex. Affected by the processing accuracy and movement coordination of each component, the ceiling mounting frame is prone to shaking, jamming and other problems during operation, which reduces the stability and smoothness of the ceiling mounting frame during operation, thereby affecting the user experience.

[0041] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0042] It should be noted that the ceiling mounting bracket provided in the embodiment of the present application is used to install the device to be installed at the use position. The device to be installed may be a television, a tablet, a clock or other device. The use position may be a ceiling, a shed ceiling or other location. As an example, the device to be installed is a television, and the use position is the ceiling, that is, the ceiling mounting bracket can install the television on the ceiling for use. The following description assumes that the device to be installed is a television, and the use position is the ceiling.

[0043] See also Figure 1 and Figure 2, the embodiment of the present application provides a ceiling mounting frame. The ceiling mounting frame includes a fixed structure 10, a mounting structure 20, a rotating connection member 70, a connecting rod 50 and an electric push rod 30. The mounting structure 20 is rotatably connected to the fixed structure 10. The mounting structure 20 has a folding configuration and an unfolding configuration. One end of the rotating connection member 70 is fixedly connected to the fixed structure 10, and the other end of the rotating connection member 70 is rotatably connected to the mounting structure 20. The connecting rod 50 has a first end 51 and a second end 52 opposite to each other. The first end 51 is rotatably connected to the mounting structure 20. The fixed structure 10 is provided with a slide groove 12. The second end 52 is arranged in the slide groove 12 and can rotate in the slide groove 12. When the mounting structure 20 rotates relative to the fixed structure 10, the second end 52 slides along the slide groove 12. One end of the electric push rod 30 is rotatably connected to the fixed structure 10, and the other end is rotatably connected to the mounting structure 20. The electric push rod 30 is used to drive the mounting structure 20 to rotate relative to the fixed structure 10, so that the mounting structure 20 switches between the folding configuration and the unfolding configuration.

[0044] like Figure 1 As shown, when the mounting structure 20 is in the folded configuration, the mounting structure 20 and the fixed structure 10 are folded relative to each other. Figure 2 As shown, when the mounting structure 20 is in the deployed configuration, there is a certain angle between the mounting structure 20 and the fixed structure 10 .

[0045] It is understandable that the slide slot 12 of the fixed structure 10 has a limiting effect on the relative rotation angle of the mounting structure 20 and the fixed structure 10. When the second end 52 slides to the opposite ends of the slide slot 12 along the length direction, the fixed structure 10 and the mounting structure 20 cannot continue to rotate. In this way, the user can adjust the range of the rotation angle of the mounting structure 20 and the fixed structure 10 by adjusting the length of the slide slot 12.

[0046] The electric push rod 30 refers to an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. When the ceiling mounting frame of the present application is in use, the electric push rod 30 can be extended to generate a thrust on the mounting structure 20. The thrust component along the rotation direction of the mounting structure 20 can provide a rotation driving force for the mounting structure 20, so that the mounting structure 20 rotates relative to the fixed structure 10, so that the ceiling mounting frame gradually unfolds. The electric push rod 30 can also be retracted to generate a pulling force on the mounting structure 20. The thrust component along the rotation direction of the mounting structure 20 can provide a rotation driving force for the mounting structure 20, so that the mounting structure 20 rotates relative to the fixed structure 10, so that the ceiling mounting frame tends to a folded state.

[0047] The ceiling mounting frame provided by the embodiment of the present application can be used by the user to mount the TV on the mounting structure 20 and to mount the fixed structure 10 on the ceiling. One end of the rotating connector 70 is fixedly connected to the fixed structure 10, and the other end is rotatably connected to the mounting structure 20, so that the mounting structure 20 and the fixed structure 10 can be driven by the electric push rod 30 through the rotating connector 70 to achieve relative rotation, so that the mounting structure 20 can switch between the unfolded configuration and the folded configuration. In the process of the fixed structure 10 rotating relative to the mounting structure 20, the first end 51 of the connecting rod 50 is rotatably connected to the mounting structure 20, and the second end 52 can rotate in the slide groove 12 of the fixed structure 10 and can slide along the slide groove 12. Compared with the existing complex multi-link matching structure set between the mounting structure 20 and the fixed structure 10, the structure and movement mode of the connecting rod 50 of the present application are relatively simple, which reduces the requirements for accuracy and component matching, so that the mounting structure 20 is not easy to get stuck or shake when rotating relative to the fixed structure 10, thereby improving the smoothness and stability of the operation of the ceiling mounting frame.

[0048] In addition, the arrangement of the connecting rod 50 also improves the stability of the fixed structure 10 and the mounting structure 20 during the rotation process, and the second end 52 of the connecting rod 50 can slide in the slide groove 12, so that the relative rotation of the mounting structure 20 and the fixed structure 10 is more stable and reliable. At the same time, the arrangement of the connecting rod 50 also improves the overall strength of the ceiling mounting frame, making the overall structure of the ceiling mounting frame more stable.

[0049] In some embodiments, see Figure 1 and Figure 2 The mounting structure 20 has a first connection position 21. The mounting structure 20 is rotatably connected to the fixed structure 10 via the first connection position 21. The fixed structure 10 has a second connection position 11. The fixed structure 10 is rotatably connected to the electric push rod 30 via the second connection position 11. Along the length direction of the fixed structure 10, there is a first distance between the first connection position 21 and the second connection position 11. The first distance is greater than 1 / 9 of the length of the fixed structure 10, and the first distance is less than 1 / 2 of the length of the fixed structure 10.

[0050] It should be noted that the further away the second connection position 11 is from the first connection position 21, the greater the component force of the electric push rod 30 acting on the mounting structure 20 will be, so the electric push rod 30 only needs a smaller thrust to push the mounting structure 20 to rotate relative to the fixed structure 10. However, in this case, the minimum angle that can be formed by the relative rotation of the mounting structure 20 and the fixed structure 10 is larger, so that the thickness of the ceiling mounting frame along the distribution direction of the mounting structure 20 and the fixed structure 10 is larger. The closer the second connection position 11 is to the first connection position 21, the smaller the minimum angle that can be formed by the mounting structure 20 and the fixed structure 10, so that the thickness of the ceiling mounting frame along the distribution direction of the mounting structure 20 and the fixed structure 10 is smaller. However, at this time, the component force of the thrust of the electric push rod 30 acting on the mounting structure 20 along the rotation direction of the mounting structure 20 will become smaller, so it is necessary to select an electric push rod 30 with greater power.

[0051] Therefore, based on the folding performance of the mounting structure 20 and the fixed structure 10 and the power of the electric push rod 30, setting the first distance to be greater than 1 / 9 of the length of the fixed structure 10 and less than 1 / 2 of the length of the fixed structure 10 is the best use state. Specifically, the first distance between the first connection position 21 and the second connection position 11 can be set to be greater than 1 / 8 of the length of the fixed structure 10 and less than 1 / 3 of the length of the fixed structure 10; or, the first distance can also be set to be greater than 1 / 7 of the length of the fixed structure 10 and less than 1 / 4 of the length of the fixed structure 10, etc.

[0052] In this way, setting the first distance to the above-mentioned optimal use state allows the user to select an electric push rod 30 with appropriate power, thereby reducing the cost of the electric push rod 30, while also reducing the thickness of the ceiling mounting frame and the installation space occupied by the ceiling mounting frame.

[0053] In some embodiments, see Figure 1 and Figure 2 The rotating connecting member 70 includes a first connecting section 71 and a second connecting section 72. The first connecting section 71 and the second connecting section 72 are connected to form an angle. The first connecting section 71 is fixedly connected to the fixed structure 10. The second connecting section 72 is rotatably connected to the mounting structure 20.

[0054] Specifically, the angle formed between the first connecting section 71 and the second connecting section 72 may be 80°, 90°, 100°, 110°, 120°, etc.

[0055] The fixing structure 10 can be fixedly connected to the first connection section 71 by fasteners such as bolts and screws. The mounting structure 20 can be rotatably connected to the second connection section 72 by a pin, so that the mounting structure 20 can rotate relative to the fixing structure 10 by rotatably connecting with the rotating connector 70.

[0056] By setting the rotating connecting member 70, the positions of the rotation centers of the mounting structure 20 and the fixed structure 10 are adjusted, so that when the mounting structure 20 is rotated to the folded configuration, the distance between the mounting structure 20 and the fixed structure 10 is reduced, thereby reducing the overall thickness of the ceiling mounting frame and reducing the installation space occupied by the ceiling mounting frame.

[0057] In some embodiments, see Figures 2 to 5 The ceiling mounting frame further includes a roller structure 60. The roller structure 60 is disposed in the slide slot 12 and is capable of rotating around a first axis in the slide slot 12. The second end 52 of the connecting rod 50 is rotatably connected to the roller structure 60. The first axis is parallel to the axis of rotation of the mounting structure 20 relative to the fixed structure 10.

[0058] The axis about which the mounting structure 20 rotates relative to the fixed structure 10 is defined as the second axis. Figure 2 The axis L1 shown in FIG. Figure 2 The axis L2 is shown in the figure, and the axis L1 is parallel to the axis L2.

[0059] The roller structure 60 is in rolling contact with the slide groove 12 of the fixed structure 10, which reduces the friction resistance between the connecting rod 50 and the groove wall of the slide groove 12, making the movement of the connecting rod 50 smoother and less prone to jamming, thereby improving the problem of easy wear of the connecting rod 50 during long-term use. At the same time, the roller structure 60 has low noise during the rolling process.

[0060] In some embodiments, see Figure 6 The roller structure 60 includes a connecting shaft 62 and two groups of rollers 61. The two groups of rollers 61 are arranged on the connecting shaft 62 at intervals. The fixed structure 10 is provided with two groups of slide grooves 12, and the two groups of slide grooves 12 are arranged at intervals. Each group of rollers 61 is arranged in each group of slide grooves 12, and each group of rollers 61 can rotate around the first axis in each group of slide grooves 12. The second ends 52 of the two groups of connecting rods 50 are respectively arranged at opposite ends of the connecting shaft 62.

[0061] The connecting shaft 62 drives the two rollers 61 to roll in coordination, so that the two sets of connecting rods 50 slide synchronously in the slide grooves 12 of the fixed structure 10, further improving the stability of the mounting structure 20 and the fixed structure 10 during the relative rotation process. In addition, the connecting shaft 62 has a supporting effect on the rollers 61, improving the stability of the rollers 61 during the rotation and sliding process.

[0062] In some embodiments, see Figure 2 The connecting rods 50 are arranged in two groups. The two groups of connecting rods 50 are spaced apart in the extending direction of the first axis.

[0063] The two groups of connecting rods 50 are defined as a first connecting rod group and a second connecting rod group, wherein the first connecting rod group may include at least one connecting rod 50 , and the second connecting rod group may also include at least one connecting rod 50 .

[0064] By having two sets of connecting rods 50 distributed at intervals on the ceiling mounting frame, the stability of the mounting structure 20 and the fixed structure 10 during rotation is further improved, and the overall structural strength of the ceiling mounting frame is also improved, so that the ceiling mounting frame is subjected to more uniform force when carrying the TV, thereby improving the durability and reliability of the ceiling mounting frame.

[0065] In some embodiments, see Figures 2 to 4 The ceiling mounting bracket further includes a locking mechanism 40. The locking mechanism 40 is used to lock the mounting structure 20 and the fixed structure 10 relative to each other when the mounting structure 20 is rotated relative to the fixed structure 10 to a folded configuration.

[0066] When in use, the electric push rod 30 drives the mounting structure 20 to rotate relative to the fixed structure 10. When the mounting structure 20 is rotated to a folded configuration relative to the fixed structure 10, the user can lock the mounting structure 20 and the fixed structure 10 through the locking mechanism 40, so that the mounting structure 20 cannot continue to rotate relative to the fixed structure 10, thereby limiting the rotation of the TV mounted on the mounting structure 20.

[0067] In this way, when the mounting structure 20 is in the folded configuration, the weight of the TV acts on the mounting structure 20, and the fixing structure 10 fixed to the ceiling can provide a pulling force to the mounting structure 20 through the locking mechanism 40 to offset the weight of the TV. In this way, it is not necessary to offset the weight of the TV through the self-locking force of the internal components of the electric linear actuator 30, thereby reducing the risk of wear of the internal components of the electric linear actuator 30 and increasing the service life of the electric linear actuator 30.

[0068] In some embodiments, see Figure 1 and Figure 2 The locking mechanism 40 includes a first locking structure 41 and a second locking structure 42. The first locking structure 41 is disposed on the fixed structure 10. The second locking structure 42 is disposed on the mounting structure 20. The first locking structure 41 is used to engage with the second locking structure 42 to relatively lock the mounting structure 20 and the fixed structure 10.

[0069] As an example, the first locking structure 41 and the second locking structure 42 may be snap-fit ​​structures. When the mounting structure 20 and the fixing structure 10 are relatively locked, the first locking structure 41 is snap-fitted to the second locking structure 42 .

[0070] In this way, the mounting structure 20 and the fixing structure 10 are locked by the mutual engagement of the second locking structure 42 and the first locking structure 41 , thereby improving the connection strength between the mounting structure 20 and the fixing structure 10 in the locked state.

[0071] In some embodiments, see Figures 1 to 4 The second locking structure 42 includes a connecting seat 421, two groups of abutting members 422 and an elastic structure 423. The connecting seat 421 is fixed to the mounting structure 20. The two groups of abutting members 422 are arranged at intervals on the connecting seat 421. The two groups of abutting members 422 can move toward each other, or the two groups of abutting members 422 can also move away from each other. The first locking structure 41 can be inserted between the two groups of abutting members 422. The elastic structure 423 is arranged on the connecting seat 421 and connected to the abutting members 422. The elastic structure 423 is used to provide a driving force for the two groups of abutting members 422 to move toward each other, so that the two groups of abutting members 422 can clamp the first locking structure 41 together.

[0072] The two groups of abutting members 422 are defined as a first abutting member group and a second abutting member group. The first abutting member group may include at least one abutting member 422 , and the second abutting member group may also include at least one abutting member 422 .

[0073] When the first locking structure 41 is inserted between the two groups of abutting members 422, the first locking structure 41 pushes the abutting members 422 on both sides, so that the two groups of abutting members 422 move away from each other, thereby compressing the elastic structure 423 connected to the abutting members 422 and accumulating elastic potential energy. In this way, when the external force is removed, the elastic structure 423 releases the elastic potential energy and provides a driving force for the two groups of abutting members 422 to move toward each other, so that the two groups of abutting members 422 are driven by the elastic structure 423 to press the opposite sides of the first locking structure 41, thereby making the two groups of abutting members 422 clamp the first locking structure 41 together.

[0074] The elastic structure 423 can be a spring, a spring, a torsion spring, etc.

[0075] In a possible design, the elastic structure 423 includes two groups of elastic members 4231, each group of elastic members 4231 is correspondingly connected to each group of supporting members 422, and the two groups of elastic members 4231 are respectively connected to the connecting seat 421, and can perform elastic telescopic movement toward or away from each other to drive the two groups of supporting members 422 closer or farther away respectively.

[0076] In this way, the second locking structure 42 includes multiple components, and the multiple components cooperate to achieve locking of the first locking structure 41, thereby improving the connection strength when the second locking structure 42 is locked with the first locking structure 41. When a component of the second locking structure 42 is damaged, the user can remove the component for repair and replacement, thereby improving the maintainability of the second locking structure 42.

[0077] In some embodiments, Figure 3 As shown, the connection seat 421 is provided with two sets of guide grooves 4211 spaced apart in the spacing direction of the two sets of abutting members 422, and the two sets of abutting members 422 are slidably disposed in the two sets of guide grooves 4211 correspondingly one by one, so as to move toward or away from each other along the guide grooves 4211. Specifically, in one implementation, as Figure 3 As shown, each group of guide grooves 4211 can be extended on the guide seat in a straight line; or, in another implementation, two groups of guide grooves 4211 can also be extended in an "eight" shape on the connecting seat 421. The guide grooves 4211 can guide the movement of the abutting member 422, thereby improving the movement stability of the abutting member 422.

[0078] In some embodiments, see Figure 3 The two groups of abutting members 422 are both rotatably disposed on the connecting seat 421. The rotation axes of the two groups of abutting members 422 are disposed parallel to each other.

[0079] The abutting member 422 may be a pin structure, a bearing structure, or other structure that can rotate on the connecting seat 421. When the first locking structure 41 is inserted between the two groups of abutting members 422, the abutting member 422 and the first locking structure 41 are in rolling contact, thereby reducing the friction resistance between the first locking structure 41 and the abutting member 422, which is conducive to better insertion of the first locking structure 41 between the two groups of abutting members 422.

[0080] Alternatively, in another embodiment, the surfaces of the two groups of abutting members 422 for abutting the first locking structure 41 are arc-shaped surfaces.

[0081] In this way, the friction resistance when the first locking structure 41 contacts the surfaces of the two groups of abutting members 422 is small, which is conducive to better insertion of the first locking structure 41 between the two groups of abutting members 422 .

[0082] Alternatively, in another embodiment, both groups of abutting members 422 are rotatably disposed on the connecting seat 421. The rotation axes of the two groups of abutting members 422 are disposed parallel to each other. Meanwhile, the surfaces of the two groups of abutting members 422 for abutting the first locking structure 41 are arc-shaped surfaces.

[0083] During the process of the first locking structure 41 being inserted between the two groups of abutting members 422 , the abutting members 422 and the first locking structure 41 are in rolling contact, and the contact surface is an arc-shaped surface, thereby reducing the friction resistance between the first locking structure 41 and the abutting members 422 , which is conducive to better insertion of the first locking structure 41 between the two groups of abutting members 422 .

[0084] In some embodiments, see Figures 2 to 4In the spacing direction of the two groups of abutting members 422, protrusions 411 are provided on opposite sides of the first locking structure 41. When the two groups of abutting members 422 clamp the first locking structure 41 together, the protrusions 411 are limited to the side of the abutting members 422 away from the fixing structure 10.

[0085] The protrusion 411 may be a bump, a convex bump or the like disposed on the first locking structure 41 .

[0086] In the process of the first locking structure 41 being inserted between the two groups of abutting members 422, the protrusions 411 on the opposite sides of the first locking structure 41 can respectively abut against the two groups of abutting members 422, and each protrusion 411 can move on each abutting member 422. At this time, the two groups of abutting members 422 are respectively pushed by the protrusions 411 and move in opposite directions, so that the distance between the two groups of abutting members 422 increases. When the two protrusions 411 move to the side of the two groups of abutting members 422 away from the fixed structure 10, the two groups of abutting members 422 move toward each other under the drive of the elastic structure 423, so that the distance between the two groups of abutting members 422 decreases. When the external force is removed, since the distance between the two groups of abutting members 422 is smaller than the width of the first locking structure 41 at the two protrusions 411, it is difficult for the two protrusions 411 to move out from between the two groups of abutting members 422 without the help of external force.

[0087] By setting the protrusion 411, the first locking structure 41 and the second locking structure 42 can limit each other, thereby improving the connection stability between the mounting structure 20 and the fixed structure 10, improving the fixing effect of the mounting structure 20 when it is rotated relative to the fixed structure 10 to a folded configuration, and reducing the risk of the mounting structure 20 detaching from the fixed structure 10 when in the folded configuration.

[0088] In some embodiments, Figure 4 As shown, the protrusion 411 can be elastically deformed in the spacing direction of the two sets of abutting members 422 .

[0089] When the first locking structure 41 is subjected to external force, the two protrusions 411 can be elastically deformed in the spacing direction of the two groups of supporting parts 422, so that the two protrusions 411 are relatively close to each other, thereby reducing the width of the first locking structure 41 in the spacing direction of the two groups of supporting parts 422; the two protrusions 411 can also be elastically deformed in the spacing direction of the two groups of supporting parts 422, so that the two protrusions 411 are relatively far away from each other, thereby expanding the width of the first locking structure 41 in the spacing direction of the two groups of supporting parts 422.

[0090] The elastic deformation of the two protrusions 411 can reduce the width of the first locking structure 41 in the spacing direction of the two groups of abutments 422, making it easier for the first locking structure 41 to be inserted between the two groups of abutments 422, thereby improving the adaptability of the first locking structure 41 to the second locking structure 42.

[0091] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
