Description

Technical Field

[0001] The utility model belongs to the field of lifting tables, and particularly relates to a hand-controlled structure and a lifting table thereof. Background Art

[0002] In the design of height-adjustable desks, the height is usually adjusted through a manual control mechanism. The button layout of the manual control mechanism is a key factor, directly affecting the user experience and safety. Traditional manual control mechanisms for height-adjustable desks often have buttons on the front. Although this design is convenient for users, it also poses a significant risk of accidental touch.

[0003] Prior art, such as patent publication CN214592479U, discloses a hand controller for a height-adjustable table. The control panel is located on the front of the controller, with a display area and a button area, and is angled 120°-180° with the mounting plate. While placing the button area on the front of the controller facilitates operation, it also increases the risk of accidental touches. Because the hand controller itself is relatively small, the button area is located entirely on the front, further reducing the size of individual buttons. This increases the risk of users accidentally touching other buttons during operation. Summary of the Invention

[0004] In response to the problems in the prior art, the present invention proposes a hand-controlled structure and a lifting table thereof, which drives the desktop of the lifting table to rise and fall by a paddle, and arranges other buttons on both sides of the paddle to prevent the user from accidentally touching other buttons when operating the paddle, thereby reducing the risk of accidental touch and improving the convenience of operation; at the same time, the anti-slip part prevents the user from slipping when operating the paddle, causing the paddle to rebound quickly and cause a greater impact, thereby increasing the service life of the paddle.

[0005] The present invention is implemented as follows: a hand-controlled structure includes a mounting assembly fixed to a table, an electric control board is provided in the mounting assembly, and a paddle hinged to the mounting assembly, a hinge shaft is provided at the hinge of the paddle, and the paddle swings up and down around the hinge shaft; the paddle is used to drive the desktop of the lifting table to rise and fall, when the paddle swings upward, the desktop of the lifting table is driven to rise, and when the paddle swings downward, the desktop of the lifting table is driven to fall; by the swinging direction of the paddle corresponding to the lifting and lowering of the desktop of the lifting table, the control effect of the hand-controlled structure is more intuitive, and the user's operating experience and convenience are improved.

[0006] The paddle is provided with a first contact and a second contact, and the first contact and the second contact are respectively provided on both sides of the hinge shaft; the electric control panel is provided with a third contact and a fourth contact corresponding to the first contact and the second contact respectively;

[0007] When the paddle is in a horizontal state, the contacts do not touch each other, disconnecting the circuit that controls the desktop of the lifting table, thereby maintaining the desktop of the lifting table at a specific height, thereby improving the stability of the lifting table;

[0008] When the paddle swings upward, the first contact contacts the third contact, and the second contact separates from the fourth contact; when the paddle swings downward, the second contact contacts the fourth contact, and the first contact separates from the third contact; the up and down swinging of the paddle to make different contacts contact and separate not only simplifies the circuit control logic, but also reduces the possibility of failure caused by confusion in the contact state, ensures that the user can accurately trigger the expected function each time they operate, and improves the reliability of the system and the accuracy of user operations.

[0009] The paddle is also provided with an elastic unit, one end of which is fixed to the paddle, and the other end is elastically connected to the mounting assembly; the elastic unit is used to drive the paddle to automatically reset after swinging, and when the user releases the paddle, the paddle returns to a horizontal state, thereby improving the convenience of using the paddle.

[0010] The top of the paddle is recessed, forming an anti-slip feature. The paddle also includes multiple buttons located on either side. The anti-slip feature prevents the paddle from slipping when operated, which could cause a rapid rebound and significant impact, thereby increasing its lifespan. The buttons on either side of the paddle naturally guide the user to specific gestures, such as pressing with the side of a thumb or index finger, reducing the risk of accidental touches when operating the paddle.

[0011] Preferably, the paddle includes a pressing portion and a hinge portion, the hinge shaft, the first contact and the second contact are all arranged on the hinge portion, and the hinge portion extends into the mounting assembly, so that all contacts are arranged inside the mounting assembly, and thus each contact only contacts with the corresponding contact, avoiding accidental contact of the contact due to external factors, and improving the reliability of each contact; the pressing portion is exposed to the mounting assembly and is gradually tilted downward from the inside to the outside, so that the paddle is ergonomic and improves the operating convenience of the paddle.

[0012] Specifically, the mounting assembly includes a mounting top plate and a mounting bottom plate, and the mounting bottom plate is buckled and connected to the mounting top plate from bottom to top, so that the mounting top plate and the mounting bottom plate can be connected and fixed without additional fasteners, which simplifies the mounting structure and improves the convenience of installation; a mounting cavity for the hinge part to move is provided between the mounting top plate and the mounting bottom plate, and the hinge part swings up and down in the mounting cavity, and the mounting cavity limits the swing amplitude of the hinge part, preventing the user from using too much force when turning the paddle, resulting in excessive pressure between the contacts, reducing the risk of damage to the contacts, and extending the service life of the contacts.

[0013] Specifically, the elastic unit includes elastic legs corresponding to the first and second contacts, respectively. The elastic legs are arc-shaped, with one end fixedly connected to the hinged portion and the other end elastically connected to the mounting base. Due to the limited space in the mounting cavity, the arc-shaped elastic legs can provide greater elastic force than compression springs, thereby improving the stability and reliability of the elastic unit.

[0014] Specifically, the pressing portion is further provided with a display unit, the display surface of which is located at the top of the pressing portion. The display unit is used to display the parameters of the lifting table, such as the tabletop height. After adjusting the lifting table, the user can record the parameters of the lifting table through the display unit. When the parameters change, the lifting table can be quickly adjusted based on the recorded parameters, thereby improving the adjustment convenience of the lifting table.

[0015] Specifically, the pressing portion is provided with a U-shaped light bar, located on the side of the pressing portion; the buttons are symmetrically located at both ends of the light bar. The light bar displays the current status of the lift table, facilitating user adjustment, improving the convenience of the lift table and enhancing the aesthetics of the hand-operated structure.

[0016] Preferably, the first contact and the second contact gradually decrease from bottom to top, forming a frustum shape, and the radial dimensions of the tops of the first contact and the second contact are respectively smaller than the radial dimensions of the third contact and the fourth contact, thereby preventing the accumulation of dimensional errors and installation errors between various parts, which may cause the first contact and the second contact to be unable to align with the third contact and the fourth contact, thereby improving the reliability of the first contact and the second contact.

[0017] Preferably, the mounting assembly is provided with a mounting hole, the bottom of the mounting hole is recessed upward from bottom to top to form a sunken platform, the screws for fixing the mounting assembly pass through the mounting hole from bottom to top, and the heads of the screws are hidden in the sunken platform to prevent the heads of the screws from being exposed and injuring people, thereby improving the safety of the manual control structure.

[0018] Preferably, the mounting assembly is also provided with a wire hole, and the cable for supplying power to the electric control board passes through the wire hole and is electrically connected to the external power supply. The electric control board is powered by the external power supply so that the hand-controlled structure does not need to have its own power supply, thereby reducing the volume of the hand-controlled structure and further reducing the risk of the user being injured by the hand-controlled structure.

[0019] A lift table includes the aforementioned manual control structure, a table frame, a table top, a drive unit, and a control unit. The manual control structure is located at the bottom of the table top, which is movably connected to the table frame. The drive unit is mounted on the table frame / table top, with its output end being in transmission connection with the table top / table frame. The control unit is electrically connected to the drive unit and a circuit board. By driving the table top up and down via the drive unit, the lift table can adapt to different height requirements, thereby improving its practicality.
