[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, unless otherwise specified, "multiple" means 2 or more, and "several" means 1 or more. In addition, unless otherwise specified, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0043] Currently, due to the various sizes of loads such as televisions, when replacing loads of different sizes such as televisions on a lifting frame, the lateral distance between the operating handle and the load such as the television may be too large or too small, resulting in the operating handle being too abrupt or interfering with the replacement.

[0044] The present invention adaptively adjusts the operating handle according to the size of the load, so that the operating handle can maintain a suitable distance from the load, thereby improving the aesthetics. Moreover, when the load is replaced, the load can be avoided, thereby improving safety and saving the trouble of manual operation for the user.

[0045] Please also see Figure 1 and Figure 2 An embodiment of the present invention provides a method for adjusting an operating handle, which is applied to a bracket device and includes the following steps:

[0046] S100: Detecting the load on the lifting frame 30;

[0047] S200: If the load is lower than the preset load value, the operating handle 50 is moved to a preset position, wherein the lateral distance between the operating handle 50 at the preset position and the load 10 on the lifting frame 30 is within a first preset safety range.

[0048] When the load is lower than the preset load value, it means that the load 10 on the lifting frame 30 has been removed and a new load 10 will be replaced. In order to prevent the operating handle 50 from interfering with the replacement and installation of the new load 10, the operating handle 50 is moved to the preset position. Since the lateral distance between the operating handle 50 and the load 10 is within the first preset safety range, the distance between the operating handle 50 and the load 10 is far enough to avoid mutual interference between the operating handle 50 and the new load 10 during the replacement and installation process. In addition, the lateral distance between the operating handle 50 and the load 10 at the preset position will not be too large, so as to avoid the operating handle 50 being too far away from the load 10 in the lateral direction, which makes the operating handle 50 too abrupt and affects the aesthetics.

[0049] In this embodiment, the load object 10 mounted on the lifting frame 30 is a display screen. Of course, in other application scenarios, the load object 10 may also be a television, a smart tablet or other suitable electronic devices, and is not limited to a display screen.

[0050] In some optional embodiments, in step S200, the step of moving the operating handle 50 to a preset position includes:

[0051] S210a: Move the operating handle 50 to the limit position, wherein the limit position is the position where the operating handle 50 is farthest from the lifting frame 30 in the horizontal direction, and the horizontal distance between the operating handle 50 at the limit position and the lifting frame 30 is greater than the horizontal distance between the operating handle 50 at the preset position and the lifting frame 30. After the load 10 on the lifting frame 30 is removed, the operating handle 50 is first moved to the limit position, so as to minimize interference between the operating handle 50 and the load 10 when the load 10 is installed on the lifting frame 30.

[0052] In some optional embodiments, after the step of moving the operating handle 50 to the extreme position, the method further includes:

[0053] S220a: Detect the current load on the lifting frame 30 again;

[0054] S230a: If the current load is higher than the preset load value, move the operating handle 50 until the lateral distance from the load object 10 generating the current load is within a second preset safety range, wherein the second preset safety range is less than or equal to the first preset safety range.

[0055] If the current load is higher than the preset load value, it means that the replaced load 10 is installed on the lifting frame 30. At this time, a better preset position can be determined according to the load 10 of the current load, that is, the operating handle 50 is moved from the extreme position farthest from the lifting frame 30 in the horizontal direction toward the replaced load 10, until the horizontal distance between the operating handle 50 and the replaced load 10 is within the second preset safety range, so that the horizontal distance between the operating handle 50 and the load 10 generating the current load can be minimized, so that the operating handle 50 is closer to the load 10 of the current load, improving the aesthetics. Among them, the method of determining a better preset position according to the load 10 of the current load can be by obtaining the horizontal size of the load 10 of the current load, and then determining a preset position as close as possible to the load 10 of the previous load.

[0056] In some optional embodiments, in step S210a, the step of moving the operating handle 50 to the extreme position includes:

[0057] S211 a: Move the operating handle 50 to the limit position at a first speed.

[0058] In step S230a, the step of moving the operating handle 50 until the lateral distance from the load object 10 generating the current load is within a second preset safety range includes:

[0059] S231 a: Move the operating handle 50 to a second preset safety range at a second speed, wherein the second speed is lower than the first speed.

[0060] When the operating handle 50 moves to the limit position, there is no load 10 installed on the lifting frame 30, and the operating handle 50 moves away from the lifting frame 30, so the operating handle 50 is not easy to collide with other structures. At this time, the operating handle 50 can move at a faster first speed, thereby shortening the time to move to the limit position, thereby shortening the waiting time of the user, and avoiding the situation where the user needs to wait for a long time for the operating handle 50 to move into place before installing the load 10.

[0061] When the operating handle 50 moves from the extreme position to the second preset safety range, since there is a load 10 on the lifting frame 30 at this time, in order to prevent the operating handle 50 from crossing the second preset safety range or even colliding with the load 10 due to inertia, the operating handle 50 moves at a second speed slower than the first speed, thereby facilitating accurate control of the stop position of the operating handle 50.

[0062] In order to shorten the time it takes for the operating handle 50 to move into the second preset safety range, in some optional implementations, in step S231 a, the step of moving the operating handle 50 into the second preset safety range at the second speed includes:

[0063] S2311 a: Detecting the real-time horizontal distance between the operating handle 50 and the load 10 generating the current load;

[0064] S2312a: When the real-time spacing is greater than the preset spacing, the operating handle 50 is controlled to perform an accelerating movement;

[0065] S2313a: When the real-time spacing is smaller than the preset spacing, the operating handle 50 performs a deceleration movement, wherein the preset spacing is larger than the minimum value of the second preset safety range.

[0066] When the real-time spacing is greater than the preset spacing, the operating handle 50 is still far away from the current load 10, and there is no need to worry about the operating handle 50 colliding with other structures. At this time, the operating handle 50 can continue to accelerate and move at a faster speed, thereby shortening the moving time of the operating handle 50.

[0067] When the real-time spacing is smaller than the preset spacing, the operating handle 50 is relatively close to the load 10 of the current load. In order to prevent the operating handle 50 from exceeding the second preset safety range or colliding with the load 10 due to inertia, the operating handle 50 performs a deceleration movement, thereby gradually slowing down the speed of the operating handle 50 until the operating handle 50 stops moving.

[0068] By planning the movement of the operating handle 50 to accelerate first and then decelerate, not only the movement time of the operating handle 50 is shortened and the adjustment efficiency is improved, but also the position of the operating handle 50 can be controlled more accurately. In addition, the safety factor of the overall movement of the operating handle 50 is improved to avoid collision between the operating handle 50 and the load 10 or other structures.

[0069] In some optional embodiments, in step S211 a, the step of moving the operating handle 50 to the limit position at a first speed includes:

[0070] S2111 a: Move the operating handle 50 to the limit position in an accelerated motion.

[0071] Accelerating the movement of the operating handle 50 to the extreme position can shorten the time consumed by the movement of the operating handle 50 , thereby improving the position adjustment efficiency of the operating handle 50 , wherein the first speed can be accelerated to the extreme speed at which the adjustment assembly 70 can drive the operating handle 50 to move.

[0072] In some optional embodiments, in step S200, if the load is lower than the preset load value, the step of moving the operating handle 50 to a preset position includes:

[0073] S210b: Obtain the historical replacement order of the load 10 on the lifting frame 30.

[0074] S220b: Determine the lateral dimension of the next load 10 to be replaced based on the historical replacement order, and move the operating handle 50 to a preset position based on the lateral dimension, wherein the lateral spacing between the operating handle 50 at the preset position and the load 10 to be replaced is within a third preset safety range, and the third preset safety range is less than or equal to the first preset safety range.

[0075] According to the historical replacement sequence of the load 10, it can be predicted that the load 10 that may be replaced on the lifting frame 30 next time can be predicted, and then the operating handle 50 can be moved to a position within the third preset safety range according to the corresponding lateral size of the load 10. For example, the historical replacement sequence of the load 10 is load 10A, load 10B, load 10C, load 10A, load 10B, load 10C, and load 10A. The load 10 last installed on the lifting frame 30 is load 10A. According to the historical replacement sequence of the load 10, it is concluded that each time the load 10A is removed, the next load 10 installed on the lifting frame 30 is most likely to be load 10B. Therefore, it is predicted that the next load 10 replaced on the lifting frame 30 is load 10B. According to the corresponding lateral size of the load 10B, the operating handle 50 is moved to a preset position so that the lateral distance between the operating handle 50 and the load 10B is within the third preset safety range. Since the operating handle 50 can be directly moved to the preset position without having to move to the extreme position first and then to the preset position, the moving stroke of the operating handle 50 is greatly shortened, and the position adjustment efficiency of the operating handle 50 is improved.

[0076] In some optional embodiments, in step S200, if the load is lower than the preset load value, the step of moving the operating handle 50 to a preset position includes:

[0077] S210c: Obtain historical replacement data of the load 10 on the lifting frame 30, and determine the replacement frequency based on the historical replacement data.

[0078] Among them, the number of times different loads 10 are replaced on the lifting rack 30 can be determined according to the historical replacement data of the load 10, and the replacement frequency can be determined according to the replacement number. The more the replacement number, the greater the replacement frequency. For example, in the historical replacement data, the number of times the load 10A is replaced on the lifting rack 30 is 30 times, the number of times the load 10B is replaced on the lifting rack 30 is 40 times, the number of times the load 10C is replaced on the lifting rack 30 is 60 times, the number of times the load 10D is replaced on the lifting rack 30 is 50 times, and the number of times the load 10E is replaced on the lifting rack 30 is 20 times. Therefore, it can be seen that the replacement frequency of the load 10C is the largest, followed by the load 10D, the load 10B, the load 10A and the load 10E.

[0079] S220c: Predicting a set of lateral dimensions of the load 10 to be replaced according to the replacement frequency, determining a maximum movement spacing based on the lateral dimension set, and moving the operating handle 50 to a preset position according to the maximum movement spacing, wherein the lateral spacing between the operating handle 50 at the preset position and the load 10 to be replaced is within a fourth preset safety range, and the fourth preset safety range is less than or equal to the first preset safety range.

[0080] The transverse dimension set is determined by obtaining the transverse dimensions corresponding to n loads 10 with relatively high replacement frequencies, where n is greater than or equal to 1, wherein the load 10 with relatively high replacement frequency is the load 10 with high probability to be replaced next on the lifting frame 30. For example, the replacement frequencies from high to low are load 10C, load 10D, load 10B, load 10A and load 10E, and n is 3. Then, load 10C, load 10D and load 10B are likely to be the next load 10 replaced on the lifting frame 30, and the transverse dimension set includes the transverse dimension of load 10C, the transverse dimension of load 10D and the transverse dimension of load 10B.

[0081] Since the loads 10 that are replaced frequently may all be installed on the lifting frame 30, in order to prevent the operating handle 50 from colliding with the load 10, the largest transverse dimension in the transverse dimension set is selected, and the maximum moving distance is determined according to the largest transverse dimension. For example, among the loads 10C, 10D, and 10B, the transverse dimension of the load 10D is the largest, and the maximum moving distance is determined according to the transverse dimension of the load 10D. After the operating handle 50 moves to the preset position according to the maximum moving distance, the lifting frame 30 replaces the load 10C, the load 10D, or the load 10B, and the operating handle 50 will not interfere with the load 10, thereby improving safety. Moreover, since the operating handle 50 can be directly moved to the preset position without moving to the extreme position first and then to the preset position, the moving stroke of the operating handle 50 is greatly shortened, and the position adjustment efficiency of the operating handle 50 is improved.

[0082] The historical replacement order or historical replacement data of the load object 10 can be obtained by detecting and recording the data of the load object 10 on the lifting frame 30 each time the load is installed on the lifting frame 30 , thereby obtaining the historical replacement order or historical replacement data of the load object 10 .

[0083] The data detection method of the load 10 can be designed according to actual needs. For example, the weight of the load 10 can be detected to determine the type of the load 10. For example, the weight of the load 10A is a, the weight of the load 10B is b, and the weight of the load 10C is c. The type of the load 10 is determined by the weight of the load 10, and then the corresponding lateral size is obtained according to the type of the load 10; or, the detection image of the load 10 on the lifting frame 30 can be obtained by an image detection device, and then the detection image is compared with the standard image of each type of load 10 to determine the type of the load 10; or, a QR code or other type of label is set on the load 10, and after the load 10 is placed on the lifting frame 30, the QR code or other type of label of the load 10 is identified to obtain information such as the type of the load 10.

[0084] In some optional embodiments, the step of detecting the load on the lifting frame 30 includes: detecting the pressure signal between the lifting frame 30 and the wall mount 32. Figure 3The lifting frame 30 is provided with a wall mount 32, and the load 10 is mounted on the lifting frame 30 through the wall mount 32. A pressure sensor is connected between the wall mount 32 and the lifting frame 30, and a pressure signal is obtained through the pressure sensor to detect the load of the lifting frame 30. Of course, in other embodiments, other methods can also be used to detect the load on the lifting frame 30, for example, a detection image on the lifting frame 30 is obtained, and whether there is a load 10 on the lifting frame 30 is determined by detecting whether there is a load 10 in the image, thereby detecting the load of the lifting frame 30; or, a QR code or other type of label is set at a specific part of the load 10, and by detecting the QR code or other type of label, it can be determined whether there is a load on the lifting frame 30.

[0085] Please also see Figure 2 and Figure 3 Another embodiment of the present invention provides a bracket device, which uses the above-mentioned operating handle adjustment method to adjust the operating handle 50. The bracket device includes: a control unit, a base frame 20, a lifting frame 30, a load detection element 40, an operating handle 50, a spacing detection element 60 and an adjustment component 70.

[0086] The control unit may be a device with a control function such as a control box, and the control unit may be integrated on the back of the bracket device.

[0087] The lifting frame 30 is used to install the load 10. The lifting frame 30 cooperates with the base frame 20 to drive the load 10 to rise and fall. The specific structure of the lifting frame 30 can be designed according to actual needs. For example, in this embodiment, the lifting frame 30 includes an intermediate connecting frame 31, a wall mounting frame 32 and a plurality of lifting tubes 33. The intermediate connecting frame 31 is connected between the plurality of lifting tubes 33. The wall mounting frame 32 is arranged on the intermediate connecting frame 31.

The pressure sensor is arranged between the intermediate connecting frame 31 and the wall bracket 32, and the load object 10 is installed on the wall bracket 32.

[0089] The operating handle 50 is transmission-connected to the lifting frame 30 to control the lifting and lowering of the lifting frame 30 , and the operating handle 50 can reciprocate laterally relative to the lifting frame 30 .

For example, in this embodiment, the adjustment component 70 includes a sliding tube 71, an extension tube 72 and a power component 73. The extension tube 72 is arranged in the horizontal direction. One end of the extension tube 72 is fixedly connected to the lifting frame 30.

[0094] In one embodiment, the power assembly 73 is configured as a telescopic cylinder, the fixed end of the telescopic cylinder is fixed on the lifting frame 30, and the telescopic end of the telescopic cylinder is fixedly connected to the operating handle 50. The telescopic movement of the telescopic cylinder is controlled by the control unit by utilizing the telescopic movement of the telescopic cylinder to drive the operating handle 50 to move back and forth in the lateral direction.

One end of the transmission shaft 82 is in transmission connection with the first commutator 81, and the other end of the transmission shaft 82 is arranged at The transmission tube 83 is inside and cooperates with the transmission tube 83 in a circumferential limit manner, so that the transmission shaft 82 and the transmission tube 83 cannot rotate relative to each other, and the transmission shaft 82 and the transmission tube 83 are slidably cooperated, so that the transmission shaft 82 can slide along the axial direction inside the transmission tube 83, and the transmission tube 83 is connected to the lifting mechanism 90 for driving the lifting frame 30 to move up and down. When the sliding tube 71 adjusts its position along the extension tube 72, the transmission shaft 82 can also adjust its position along the transmission tube 83, so that the transmission mechanism 80 can adapt to the position adjustment of the operating handle 50, so that the rotating handle can be stably driven and connected to the lifting mechanism 90. The lifting mechanism 90 includes a linkage shaft 91, multiple screw rods 92, multiple nuts and multiple second commutators 93. The multiple screw rods 92 are threadedly connected to the multiple nuts one by one, and one nut is located in a corresponding lifting tube 33 and connected to the corresponding lifting tube 33. A second commutator 93 is correspondingly arranged on a lifting tube 33, and a second commutator 93 is transmission-connected to a screw rod 92. The multiple second commutators 93 are transmission-connected to each other through the linkage shaft 91. The operating handle 50 is transmission-connected to the linkage shaft 91 to drive the linkage shaft 91 to rotate. When the operating handle 50 rotates, the transmission shaft 82 and the transmission tube 83 are driven to rotate through the first commutator 81. The transmission tube 83 drives the screw rod 92 to rotate through the linkage shaft 91 and the second commutator 93, so that the nut is lifted and lowered relative to the base frame 20, and then the lifting tube 33 is driven and lowered, thereby realizing the lifting and lowering of the lifting frame 30. This example is not limited to this.
