Description
Technical Field
[0001] The present application relates to the field of furniture control switches, and in particular to a two-speed adjustment hand controller. Background Art
[0002] Some electric furniture can be adjusted according to user needs, such as the lifting of tables and chairs, the angle adjustment of sofa backrests and the forward and backward movement of seat cushions. These require corresponding hand controllers to be set on the furniture so that users can adjust and control the furniture according to their needs.
[0003] The existing sofa hand controller with announcement number CN218038978U is a kind of sofa hand controller. The user turns the dial knob to make the dial knob move along a straight line. According to the different moving directions, the switch handle of the corresponding toggle switch is in the corresponding left or right position among three positions to control the sofa to adjust different postures. When the user stops turning the button, the switch handle of the toggle switch is in the middle position, and the sofa posture adjustment stops at this time.
[0004] In the above-mentioned related technologies, different users have different requirements for the posture of furniture. If the posture requirements of new users and old users are quite different, if the new user directly adjusts the posture based on the posture adjusted by the old user, it will take a lot of time to adjust, which is inconvenient and affects the user experience. Utility Model Content
[0005] In order to increase the convenience of adjustment and improve the user experience, the present application provides a hand controller with two-speed adjustment.
[0006] The present application provides a two-speed adjustment hand controller that adopts the following technical solution.
[0007] A two-speed adjustable hand controller comprises a lower shell and an upper shell detachably connected to the lower shell, wherein a toggle switch for adjusting the posture of furniture and a push switch for restoring the furniture to an initial state are arranged in the lower shell, and a button which can be rotated to control the toggle switch and can be moved in a straight line to control the push switch is arranged in the upper shell, wherein the straight line where the button controls the push switch to move and the straight line where the switch handle of the toggle switch is in the middle gear are located in the same plane.
[0008] By adopting the above technical solution, when a new user needs to make a larger posture adjustment, the button can be moved, such as pressed or pulled, to trigger the corresponding push switch, so that the furniture posture is reset to facilitate posture adjustment, thereby improving the convenience and experience of adjustment.
[0009] Optionally, the two ends of the key in the length direction are a dial end and a press end respectively, the dial end rotates around the press end to control the toggle switch, the press end can move to control the push switch, and the width of the press end is greater than the width of the dial end.
[0010] By adopting the above technical solution, the buttons can be pushed accordingly, and the width of the push end is large, which can also facilitate operations such as pressing or pulling the push end, thereby improving the operating experience of the hand controller.
[0011] Optionally, the button is formed with a guide groove for a switch handle of the toggle switch to enter, and the switch handle of the toggle switch is fixedly connected to a ball head surface that is slidably connected to the guide groove.
[0012] By adopting the above technical solution, the ball head surface can slide correspondingly in the guide groove during the key rotation process, so that the switch handle of the toggle switch that can only move in a straight line direction is not easily subjected to a large bending force during the key rotation process.
[0013] Optionally, the button is fixedly connected to a rotating shaft which is slidably connected to the upper shell and can contact the push switch to control the push switch, and the button rotates around a center line of the moving direction of the rotating shaft.
[0014] By adopting the above technical solution, the rotating shaft will not move relative to the push switch during the rotation of the key, thereby ensuring that the rotating shaft can always be directly opposite the push switch without deviation, so that pressing or pulling the key can always effectively trigger the push switch.
[0015] Optionally, a return spring is provided between the button and the upper shell to force the button to move away from the upper shell.
[0016] By adopting the above technical solution, the key is no longer forced to reset by relying solely on the reset force of the push switch itself, ensuring that the key can be reset smoothly after the push switch is triggered, so that the next key can trigger the push switch.
[0017] Optionally, a truncated cone is fixedly connected to one end of the rotating shaft close to the push switch, and an end surface of the truncated cone away from the push switch can abut against a surface of the upper shell away from the button.
[0018] By adopting the above technical solution, the key is not easily pushed out of the upper housing while the return spring applies a large restoring force to the key.
[0019] Optionally, the upper shell is formed with a lower limit groove and the button is formed with an upper limit groove, and both ends of the return spring are located in the lower limit groove and the upper limit groove in a one-to-one correspondence.
[0020] By adopting the above technical solution, the position of the return spring is kept fixed, so that the reset force applied to the key is not easily offset, thereby ensuring that the key is not easily tilted when the key is pressed.
[0021] Optionally, an oil cavity for storing lubricating oil is formed between the rotating shaft and the upper shell.
[0022] By adopting the above technical solution, the rotating shaft and the upper shell can rotate effectively.
[0023] Optionally, the button is fixedly connected with a pin tube penetrating the upper shell, the pin tube is slidably connected to the upper shell around the rotation axis of the button, the pin tube is located between the toggle switch and the push switch, and the pin tube is fixedly connected with a tube block that can abut against the surface of the upper shell facing the button.
[0024] By adopting the above technical solution, when the push switch is triggered by pressing a key, the key is not easily pressed so that the key corresponding to one end of the toggle switch is pressed down synchronously, so that the switch handle of the toggle switch is not easily subjected to pressure.
[0025] Optionally, the pin tube is detachably connected to a limit pin passing through the upper shell, and the limit pin is plugged with a gasket, which abuts against the surface of the upper shell away from the button under the action of the limit pin, and the direction in which the limit pin passes through the upper shell is consistent with the direction in which the button controls the press switch to move.
[0026] By adopting the above technical solution, the gasket makes it difficult for the key to separate from the upper shell, and the limit pin also helps the key to move and rotate stably.
[0027] In summary, this application has the following beneficial effects:
[0028] When a new user needs to make a larger posture adjustment, he can move the button to trigger the corresponding push switch to reset the furniture posture so that the posture adjustment can be carried out, improving the convenience and experience of adjustment.

DETAILED DESCRIPTION
[0035] The present application is further described in detail below in conjunction with the accompanying drawings.
[0036] The present application embodiment discloses a two-speed adjustment hand controller, referring to Figure 1 and Figure 2 , comprising a lower shell 1 mounted on the furniture, an upper shell 2 being clamped at one side of the opening of the lower shell 1, a toggle switch 3 and a push switch 31 being detachably connected inside the lower shell 1, a button 32 being installed at one side of the upper shell 2 away from the lower shell 1, the button 32 being able to control the toggle switch 3 to adjust the posture of the furniture and to control the push switch 31 to restore the furniture to its initial posture.
[0037] Reference Figure 1 The two ends of the length direction of the button 32 are a dial end 33 and a push end 34, respectively. The dial end 33 corresponds to the toggle switch 3. The dial end 33 can rotate around the push end 34, so that the switch handle of the toggle switch 3 can be driven to move accordingly. The push end 34 can move in a straight line direction to trigger the push switch 31. The straight line where the push end 34 moves and the straight line where the switch handle of the toggle switch 3 is in the middle gear are located in the same plane. The moving direction of the push end 34 is not limited. It can be pressed or pulled in any direction, as long as the switch handle of the toggle switch 3 does not move synchronously during the movement of the push end 34. In this embodiment, the push end 34 needs to be pressed by the user, that is, the moving direction of the push end 34 is consistent with the direction of the rotation axis of the dial end 33. And the width of the push end 34 is much larger than the width of the dial end 33, so that the user can effectively press the push end 34.
[0038] Reference Figure 2 and Figure 3The rotating point of the push end 34 is coaxially fixedly connected with a rotating shaft 37, which is inserted and slidably connected to the upper shell 2. The end of the rotating shaft 37 away from the button 32 can abut against the push switch 31 to trigger the push switch 31 to control the furniture to reset its posture. An oil chamber 26 is formed between the rotating shaft 37 and the upper shell 2. Lubricating oil is placed in the oil chamber 26 so that the rotation of the rotating shaft 37 is not easily subject to large friction. When the push end 34 is pressed to the stroke limit, the oil chamber 26 reaches the minimum volume and the lubricating oil just fills the oil chamber 26. The button 32 is formed with an upper limit groove 22 around the rotating shaft 37, and the upper shell 2 is formed with a lower limit groove 21 around the rotating shaft 37. A return spring 38 is placed in the upper limit groove 22 and the lower limit groove 21. The return spring 38 forces the push end 34 to move away from the upper shell 2. A truncated cone 39 is coaxially fixedly connected to one end of the shaft 37 away from the button 32. The truncated cone 39 has the largest diameter at the end connected to the shaft 37. The periphery of the end face with the largest diameter of the truncated cone 39 can abut against the surface of the upper shell 2 away from the button 32, so that the button 32 is not easily pushed out of the upper shell 2 by the return spring 38.
[0039] Reference Figure 4 A guide groove 35 is formed on the dial end 33 along the length direction of the button 32, and a ball head surface 36 is fixedly connected to the switch handle of the toggle switch 3, and the ball head surface 36 is slidably connected to the two inner walls in the length direction of the guide groove 35, so that when the dial end 33 rotates, it can effectively drive the switch handle of the toggle switch 3 to move, and it is not easy to apply a large torque to the switch handle of the toggle switch 3.
[0040] Reference Figure 2 and Figure 5 The button 32 is fixedly connected with a pin tube 23 located between the dial end 33 and the push end 34. The axis of the pin tube 23 is in the same direction as the rotation axis of the button 32. The pin tube 23 is inserted into the upper housing 2. The outer circumferential wall of the pin tube 23 is fixedly connected with a tube block 27. The tube block 27 can abut against the surface of the upper housing 2 facing the button 32. The pin tube 23 is closer to the dial end 33 than the push end 34, so that when the push end 34 is pressed, the dial end 33 is not easy to be pressed down synchronously, so that the dial end 33 is not easy to cause excessive pressure on the switch handle of the toggle switch 3. The inner wall of the end of the pin tube 23 away from the button 32 is coaxially threadedly connected with a limit pin 24. The limit pin 24 is inserted into the upper housing 2. The limit pin 24 can rotate in the upper housing 2 synchronously with the rotation of the button 32. The limiting pin 24 is inserted with a gasket 25 , and the gasket 25 abuts against the surface of the upper shell 2 away from the button 32 under the pressing action of the head of the limiting pin 24 , so that the button 32 is not easily separated from the upper shell 2 .
[0041] The implementation principle of a two-speed adjustment hand controller in an embodiment of the present application is as follows: when adjusting the posture of the furniture to a larger extent, the pressing end 34 can be pressed first to trigger the pressing switch 31 to restore the posture of the furniture to the initial state, and then the dial end 33 can be rotated to adjust the posture of the furniture in the initial state, so that the adjustment is more convenient and the experience is better.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
