Description

Technical Field

[0001] The utility model relates to the technical field of workstations, and more specifically, it relates to an anti-pinch structure for the cabin door of an intelligent workstation. Background Art

[0002] In a workstation, storage cabinets and the like are often provided to facilitate the operator to access engineering equipment from the workstation.

[0021] The present utility model will be described in detail below in conjunction with the drawings and embodiments.

[0022] The present utility model provides a cabin door anti-pinch structure for an intelligent workstation, as Figure 1As shown in the figure, it includes: a cabin body 1, a first cabin door 2, a second cabin door 3, a first upper slide rail 4, a second upper slide rail 5, a first lower slide rail 6, a second lower slide rail 7, a driving component 8 for respectively driving the first cabin door 2 and the second cabin door 3 to move, a detection component 9 for detecting obstacles around the first cabin door 2 and the second cabin door 3, and a control device; the first upper slide rail 4 and the second upper slide rail 5 are respectively detachably connected to the top end of the cabin body 1; the first lower slide rail 6 and the second lower slide rail 7 are respectively detachably connected to the bottom end of the cabin body 1; one end of the first cabin door 2 is slidably connected to the first upper slide rail 4, and the other end is slidably connected to the first lower slide rail 6; one end of the second cabin door 3 is slidably connected to the second upper slide rail 5, and the other end is slidably connected to the second lower slide rail 7; the driving component 8 is detachably connected to the cabin body 1; the first output end of the driving component 8 is in transmission connection with the first cabin door 2, and the second output end of the driving component 8 is in transmission connection with the second cabin door 3; the detection component 9 is detachably connected to the cabin body 1; the control device is detachably connected to the cabin body 1; the detection component 9 is electrically connected to the control device; the control device is electrically connected to the driving component 8.

[0023] Specifically, the driving component 8 is used to drive the first cabin door 2 and the second cabin door 3 to open or close. During the opening or closing process, the first upper slide rail 4 and the first lower slide rail 6 play a guiding role for the first cabin door 2, preventing it from shifting in position due to environmental factors during the opening or closing process. The second upper slide rail 5 and the second lower slide rail 7 play a guiding role for the second cabin door 3, preventing it from shifting in position due to environmental factors during the opening or closing process. During the opening or closing process of the first cabin door 2 and the second cabin door 3, the detection component 9 is used to detect whether the cabin door clamps an object. If an object is clamped, the control device will urgently brake the driving component 8 to avoid further clamping and causing injury, ensuring personal and property safety.

[0024] Furthermore, the detection component 9 includes: a first pressure sensor 91 for measuring the resistance when the first cabin door 2 is closed, a second pressure sensor 92 for measuring the resistance when the second cabin door 3 is closed, a first infrared sensor 93, and a second infrared sensor 94; the first pressure sensor 91 and the second pressure sensor 92 are fixedly connected to the cabin body 1; the input end of the first pressure sensor 91 abuts against the first cabin door 2; the input end of the second pressure sensor 92 abuts against the second cabin door 3; the first infrared sensor 93 is detachably connected to the cabin body 1; the second infrared sensor 94 is detachably connected to the cabin body 1.

[0025] Specifically, the first pressure sensor 91 and the second pressure sensor 92 can measure the resistance when the hatch is closed. If it exceeds the preset value, it is determined that an object is clamped, and the control device will perform an emergency brake to avoid further pinching. The first infrared sensor 93 and the second infrared sensor 94 detect whether there is an object on the closing tracks of the first hatch 2 and the second hatch 3. If there is an object, the hatch cannot be closed further, which plays a role in preventing pinching. By using a dual-detection method, the accuracy of detection and the effect of preventing pinching are further ensured.

[0026] Further, the driving assembly 8 includes: a first driving member 81, a first transmission rod, and a second transmission rod; the first driving member 81 is detachably connected to the cabin body 1; a first output end of the first driving member 81 is fixedly connected to one end of the first transmission rod, and a second output end of the first driving member 81 is fixedly connected to one end of the second transmission rod; the other end of the first transmission rod is fixedly connected to the first hatch 2; the other end of the second transmission rod is fixedly connected to the second hatch 3.

[0027] Specifically, the first driving member 81 drives the first transmission rod and the second transmission rod, thereby driving the first hatch 2 and the second hatch 3 to open or close. The first driving member 81 is electrically connected to the control device so that the first hatch 2 and the second hatch 3 can stop quickly when an emergency brake is required.

[0028] Further, it further includes: a first electromagnet 21 and a second electromagnet 31; the first electromagnet 21 and the second electromagnet 31 have the same magnetic property; the first electromagnet 21 is detachably connected to the first hatch 2; the second electromagnet 31 is detachably connected to the second hatch 3; the first electromagnet 21 and the second electromagnet 31 are both electrically connected to the control device.

[0029] Specifically, when the first hatch 2 and the second hatch 3 are about to be completely closed, the control device energizes the first electromagnet 21 and the second electromagnet 31. The first electromagnet 21 and the second electromagnet 31 have the same magnetic property, generating a certain magnetic force to slow down the speed of the first hatch 2 and the second hatch 3, providing a buffering effect when the hatch is closed, and avoiding pinching people or objects due to too fast closing speed.

[0030] Furthermore, it also includes: a first clamping block 22, a second clamping block 32 that cooperates with the first clamping block 22 to lock the first cabin door 2 and the second cabin door 3, a clamping arm 11 and a second driving member 12 used to abut the first clamping block 22 and the second clamping block 32; the first clamping block 22 is fixedly connected to the first cabin door 2; the second clamping block 32 is fixedly connected to the second cabin door 3; the second driving member 12 is detachably connected to the cabin body 1; the clamping arm 11 is transmission-connected to the output end of the second driving member 12; the second driving member 12 is electrically connected to the control device; the two ends of the clamping arm 11 can abut against one side of the first clamping block 22 and one side of the second clamping block 32 respectively; when the two ends of the clamping arm 11 are in abutment with one side of the first clamping block 22 and one side of the second clamping block 32, the other side of the first clamping block 22 abuts against the other side of the second clamping block 32.

[0031] Specifically, when the first hatch 2 and the second hatch 3 are in the closed state, the control device controls the second driving member 12 to make the clamping arm 11 clamp the first clamping block 22 and the second clamping block 32, so that the sealing of the first hatch 2 and the second hatch 3 is better, and avoids the situation in which the first hatch 2 and the second hatch 3 are not tightly fitted due to environmental factors such as vibration during the movement of the workstation, resulting in the falling of objects or water leakage.

[0032] Furthermore, it also includes: a first pull rod 23, a second pull rod 33, a brake rod 13 and a brake button 14; the first pull rod 23 is fixedly connected to the first cabin door 2 and is located on the outside of the first cabin door 2; the second pull rod 33 is fixedly connected to the second cabin door 3 and is located on the outside of the second cabin door 3; one end of the brake rod 13 is transmission connected to the clamp arm 11, and the other end is transmission connected to the brake button 14; the brake button 14 is detachably connected to the cabin body 1 and is located on the outside of the cabin body 1.

[0033] Specifically, when an emergency occurs, the brake button 14 can be used to drive the brake rod 13 to release the clamping of the clamping arm 11 on the first block 22 and the second block 32, so that the operator can open the first door 2 and the second door 3 through the first pull rod 23 and the second pull rod 33 on the first door 2 and the second door 3 to take out engineering equipment or emergency equipment, etc., further increasing safety.

[0034] Furthermore, a dust baffle 10 is provided at the sliding connection between the first hatch 2 and the second hatch 3 .

[0035] Specifically, a dust baffle 10 is provided to prevent objects from falling into the first upper slide rail 4, the second upper slide rail 5, the first lower slide rail 6 and the second lower slide rail 7, causing the first hatch 2 and the second hatch 3 to be unable to open and close normally.

[0036] Specifically, the above-mentioned control device can be an external controller or an internal controller. In this embodiment, an internal controller is adopted. The controller can be a controller with opening and closing functions such as an MCU, a PLC, a single-chip microcomputer, etc. In this embodiment, an MCU is adopted.

[0037] In the specific implementation process, when it is necessary to close the hatch, the control device controls the first driving member 81, so that through the first transmission rod and the second transmission rod, it drives the first hatch 2 to move along the guides of the first upper slide rail 4 and the first lower slide rail 6, and drives the second hatch 3 to move along the guides of the second upper slide rail 5 and the second lower slide rail 7; during the movement, the first pressure sensor 91 measures the resistance of the first hatch 2 during the movement. If the resistance exceeds the preset value, it transmits a signal to the control device to make it brake emergently; the first infrared sensor is used to identify whether there is an obstacle in the traveling path of the first hatch 2. If there is, it transmits a signal to the control device to interrupt the movement. Similarly, the second hatch 3 also has the same working principle, which will not be elaborated one by one here;

[0038] When the first hatch 2 and the second hatch 3 are about to close, the control device energizes the first electromagnet 21 on the first hatch 2 and the second electromagnet 31 on the second hatch 3, so that they generate a magnetic force to realize the buffering effect on the first hatch 2 and the second hatch 3, reduce the closing speed, and avoid pinching or clamping objects at too fast a speed, causing damage;

[0039] When the first hatch 2 and the second hatch 3 are completely closed, the second driving member 12 drives the clamping arms 11 to clamp the first clamping block 22 on the first hatch 2 and the second clamping block 32 on the second hatch 3, so that they are in mutual contact, thereby ensuring the tightness of the first hatch 2 and the second hatch 3.

[0040] The anti-pinch structure of the hatch of the intelligent workstation of the present utility model detects whether an object is clamped during the closing process of the first hatch 2 and the second hatch 3 through the detection component 9. If it is recognized that an object is clamped, the control device controls the driving component 8 to stop, protecting personal and property safety and avoiding losses; by using infrared sensors and force sensors, under double detection, more accurate anti-pinch detection is provided.

[0041] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches should also be regarded as the protection scope of the present utility model.
