Description

Technical Field

[0001] This utility model relates to a lifting pull-out basket, and more particularly to an anti-pinch lifting pull-out basket. Background Technology

[0002] Because of their height, upper kitchen cabinets often require a chair to access, making them inconvenient to use. Therefore, pull-out baskets with adjustable height have been introduced to the market. When needed, the basket moves downwards, and after use, it moves back upwards into the cabinet. Existing pull-out baskets on the market are controlled by buttons, remote controls, or voice commands, but they lack anti-pinch features. If there are items underneath the basket, improper operation may cause it to continue descending, potentially crushing items, trapping people, or even damaging the basket itself. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an anti-pinch lifting basket.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-pinch lifting basket, comprising a lifting mechanism, a lifting cabinet, and a controller. The controller controls the lifting mechanism to drive the lifting cabinet to move up and down. The lower end of the lifting cabinet is provided with a base plate, which includes an upper fixed plate and a lower movable plate. The upper fixed plate and the lower movable plate are connected by an elastic connecting component. The lower movable plate can move up and down. A micro switch is provided between the upper fixed plate and the lower movable plate. The micro switch is electrically connected to the controller. When the lifting cabinet moves downward and there is an object below the base plate, the object will push the lower movable plate upward. The upper fixed plate and the lower movable plate squeeze the micro switch, triggering a closing signal. When the controller receives the closing signal, it sends a control signal to the lifting mechanism. The lifting mechanism drives the lifting cabinet to move upward a certain distance and then stops moving.

[0005] Preferably, the base plate is equipped with a touch switch, and the touch switch is electrically connected to the controller.

[0006] Preferably, the elastic connection assembly includes an upper connecting block, a lower connecting block, and a spring disposed between the upper connecting block and the lower connecting block. The upper connecting block is connected to the lower surface of the upper fixed plate, and the lower connecting block is connected to the upper surface of the lower movable plate. The upper connecting block is provided with a first through hole, and the lower connecting block is provided with a first connecting post. The first connecting post passes through the first through hole, and a fastener is provided at the upper end of the first connecting post. The fastener prevents the lower connecting block from detaching from the upper connecting block.

[0007] Preferably, the micro switch is disposed between the upper connecting block and the lower connecting block.

[0008] Preferably, the lower connecting block is provided with a connecting seat for placing a micro switch, and the bottom of the connecting seat is provided with a wire hole.

[0009] Preferably, the microswitches are arranged in an array along the front-back and left-right directions of the base plate, with the distance between adjacent microswitches in the front-back direction not exceeding 300mm, the distance between adjacent microswitches in the left-right direction not exceeding 500mm, and the distance between the leftmost microswitch and the left side of the base plate not exceeding 250mm, and the distance between the rightmost microswitch and the right side of the base plate not exceeding 250mm.

[0010] Preferably, the spacing between adjacent microswitches in the front-to-back direction is 100-200mm.

[0011] Preferably, the spacing between adjacent microswitches in the left and right directions is 300-400mm.

[0012] The beneficial effects of this utility model are as follows: By setting an upper fixed plate and a lower movable plate that can move up and down, and setting a micro switch between the upper fixed plate and the lower movable plate, when the lower movable plate presses on an item, the micro switch is triggered, thereby stopping the lifting cabinet from moving and avoiding the situation of crushing the item or pinching the body.

[0019] like Figures 1-6As shown, an anti-pinch lifting basket includes a lifting mechanism 1, a lifting cabinet 2, and a controller (not shown in the figure). The controller controls the lifting mechanism 1 to drive the lifting cabinet 2 to move up and down. The specific structure and principle of the lifting mechanism 1, the lifting cabinet 2, and the controller can refer to existing technologies, such as the lifting baskets disclosed in announcement numbers CN217137221U and CN213849535U. The lower end of the lifting cabinet 2 is provided with a base plate 3, which includes an upper fixed plate 4 and a lower movable plate 5. The upper fixed plate 4 and the lower movable plate 5 are connected by an elastic connecting component 7. The lower movable plate 5 can move up and down. A micro switch 6 is provided between the upper fixed plate 4 and the lower movable plate 5, and the micro switch 6 is electrically connected to the controller.

[0020] In use, when the lifting cabinet 2 is stationary at its highest position, pressing down the movable plate 5 triggers the micro switch 6. The controller then controls the lifting mechanism 1 to drive the lifting cabinet 2 downwards. When the lifting cabinet 2 moves downwards, if there is an object below the base plate 3, the object will push the movable plate 5 upwards. The upper fixed plate 4 and the lower movable plate 5 will press the micro switch 6, triggering a closed signal. When the controller receives this closed signal, it sends a control signal to the lifting mechanism 1. The lifting mechanism 1 drives the lifting cabinet 2 upwards a certain distance and then stops. After removing the object below the base plate 3, pressing down the movable plate 5 again triggers the micro switch 6. The controller then controls the lifting mechanism 1 to drive the lifting cabinet 2 upwards. During the upward movement, pressing down the movable plate 5 triggers the micro switch 6, and the lifting cabinet 2 will stop moving. Then, pressing down the movable plate 5 again triggers the micro switch 6, and the lifting cabinet 2 will move downwards.

[0021] The base plate 3 is equipped with a touch switch 8, which is electrically connected to the controller. In this embodiment, the touch switch 8 is a touch strip arranged along the length of the base plate 3. Touching the touch switch 8 sends a signal to the controller. The process of controlling the lifting and lowering via the touch switch and the micro switch 6 is the same. Compared to pressing down the movable plate 5 to trigger the micro switch 6, the touch switch is more effortless and convenient. Of course, other existing technologies such as buttons, remote control, or voice control can also be used to control the lifting and lowering.

[0022] The elastic connection assembly 7 includes an upper connecting block 71, a lower connecting block 72, and a spring 73 disposed between the upper connecting block 71 and the lower connecting block 72. The upper connecting block 71 is connected to the lower surface of the upper fixed plate 4, and the lower connecting block 72 is connected to the upper surface of the lower movable plate 5. The upper connecting block 71 is provided with a first through hole 711, and the lower connecting block 72 is provided with a first connecting post 721. The first connecting post 721 passes through the first through hole 711, and a fastener 722 is provided at the upper end of the first connecting post 721. The fastener 722 prevents the lower connecting block 72 from detaching from the upper connecting block 71.

[0023] The micro switch 6 is disposed between the upper connecting block 71 and the lower connecting block 72.

[0024] The lower connecting block 72 is provided with a connecting seat 723 for placing the micro switch 6, and the bottom of the connecting seat 723 is provided with a wire hole 724.

[0025] To ensure the anti-pinch effect, the number and spacing of the elastic connecting components 7 and micro switches 6 are adjusted according to the length and width of the base plate 3. The micro switches 6 are arrayed along the front-back and left-right directions of the base plate 3. Testing shows that the spacing between adjacent micro switches 6 in the front-back direction is no greater than 300mm, and the spacing between adjacent micro switches 6 in the left-right direction is no greater than 500mm. Furthermore, the distance between the leftmost micro switch 6 and the left side of the base plate 3 is no greater than 250mm, and the distance between the rightmost micro switch 6 and the right side of the base plate 3 is no greater than 250mm. Preferably, the spacing between adjacent micro switches 6 in the front-back direction is 100-200mm. Preferably, the spacing between adjacent micro switches 6 in the left-right direction is 300-400mm.

[0026] In this embodiment, two rows of microswitches 6 are provided in the front-to-back direction, with a front-to-back spacing of ( Figure 6 The middle L2 is approximately 160mm thick, and has three rows of microswitches 6 in the left and right directions, with a left and right spacing of ( Figure 6 The middle L1 is about 320mm away from the side of the adjacent base plate 3. The micro switches 6 at the left and right ends are about 60mm away from the side of the adjacent base plate 3. As long as an object under the base plate 3 moves the movable plate 5 upward by 1-2mm, it can trigger the micro switch 6 to achieve the anti-pinch effect.
