DETAILED DESCRIPTION

[0020] The doors and drawers of traditional disinfection cabinets are fixed together and pulled out on guide rails. The door opening method is straight-pull. This straight-pull structure has the following problems: on the one hand, the upper door and the lower door cannot be opened automatically, and the degree of automation is low. On the other hand, the upper door and the lower door cannot be opened automatically at the same time, and the user needs to bend over or squat to open them.

[0021] Therefore, see Figure 1-Figure 3In order to solve the problem that the upper door and lower door of the disinfection cabinet cannot be automatically opened and closed synchronously, the present application provides a door structure and a disinfection cabinet, which includes a cabinet door 100, a cabinet body 200, a transmission mechanism 300 and a drive mechanism 400. The drive mechanism 400 is installed on the cabinet body 200. One end of the transmission mechanism 300 is connected to the output end of the drive mechanism 400, and the other end is connected to the cabinet door 100. The drive mechanism 400 can drive the transmission mechanism 300 to drive the cabinet door 100 to open or close the opening of the cabinet body 200.

[0022] Moreover, when the driving mechanism 400 is in the first operating stage, the transmission mechanism 300 can drive the cabinet door 100 to move a preset distance away from the cabinet body 200 to separate from the cabinet body 200. When the driving mechanism 400 is in the second operating stage, the transmission mechanism 300 can drive the cabinet door 100 to flip a preset angle to open the cabinet body 200.

[0023] It should be noted that the size of the preset distance depends on the following two parameters. On the one hand, it depends on the size of the assembly space of the door structure. The size of the assembly space limits the upper limit of the preset distance. On the other hand, it depends on whether the cabinet door 100 will interfere with the cabinet body 200 during the process of flipping the preset angle, that is, it limits the lower limit of the preset distance.

[0024] Similarly, the size of the preset angle depends on the following two parameters. On the one hand, it depends on the minimum opening angle of the cabinet door 100 without blocking the opening of the cabinet body 200, which limits the lower limit of the preset angle. On the other hand, it depends on whether the cabinet door 100 will interfere with the cabinet body 200 during the flipping process, which limits the upper limit of the preset angle.

[0025] Specifically, in one embodiment, the preset distance L satisfies 5 mm ≤ L ≤ 200 mm, and the preset angle A satisfies 60° ≤ A ≤ 180°.

[0026] Such an arrangement can not only open the opening of the cabinet body 200 to the greatest extent, but also avoid interference between the cabinet door 100 and the cabinet body 200 .

[0027] Preferably, in one embodiment, the preset distance L is 100 mm, and the preset angle A is 90°.

[0028] Furthermore, it should be noted that the two operating stages of the driving mechanism 400 (the first operating stage and the second operating stage) refer to the two operating time periods of the driving mechanism 400 that are successively advanced. That is, at the beginning of operation, the driving mechanism 400 drives the transmission mechanism 300 to drive the cabinet door 100 to move in a direction away from the cabinet body 200. It can be a linear movement or a curved movement. After moving a certain distance (preset distance), the driving mechanism 400 starts to drive the transmission mechanism 300 to drive the cabinet door 100 to start flipping, flipping the preset angle and opening the cabinet body 200.

[0029] Specifically, in one embodiment, Figure 2 As shown, the driving mechanism 400 includes a controller (not shown) and a driving motor 410. The controller is electrically connected to the driving motor 410. When the driving motor 410 runs for a first preset time, the cabinet door 100 moves a preset distance in a direction away from the cabinet body 200. When the driving motor 410 runs for a second preset time, the cabinet door 100 flips over a preset angle.

[0030] It should be noted that the second preset time does not include the first preset time, and the two are in a progressive relationship.

[0031] It should be noted that the first preset time and the second preset time mainly depend on the final output speed of the drive motor 410, the moving distance of the cabinet door 100 and the flipping angle of the cabinet door 100. When the latter two are fixed, the greater the final output speed of the drive motor 410, the shorter the first preset time and the second preset time, and vice versa.

[0032] Such an arrangement greatly improves the accuracy of the drive mechanism 400 driving the cabinet door 100 to move through the transmission mechanism 300.

[0033] However, the present invention is not limited thereto. In other embodiments, the driving mechanism 400 may also be a cylinder or a hydraulic mechanism.

[0034] In one embodiment, if Figure 2 As shown, the driving mechanism 400 also includes a dynamic torque sensor 420, which is electrically connected to the controller. The dynamic torque sensor 420 is arranged at the output end of the driving motor 410. When the dynamic torque sensor 420 measures that the output torque of the driving motor 410 is greater than the preset torque, the dynamic torque sensor 420 can send a signal to the controller so that the controller controls the driving motor 410 to rotate in the opposite direction.

[0035] With this arrangement, when the cabinet door 100 encounters an obstacle or pinches a hand during opening or closing, the dynamic torque sensor 420 can transmit a signal to the controller, and the controller immediately controls the drive motor 410 to run in reverse, causing the door body to move in the opposite direction to ensure the user's safety.

[0036] As described above, with such a setting, the cabinet door 100 does not distinguish between the upper door and the lower door. Instead, the transmission mechanism 300 drives the entire cabinet door 100 to move together, achieving synchronous movement of the entire cabinet door 100 and greatly improving the opening and closing efficiency of the cabinet door 100. Moreover, by driving the transmission mechanism 300 through the driving mechanism 400 to drive the cabinet door 100 to move, the automation degree of the door structure is greatly improved, and there is no need to manually open and close the cabinet door 100, effectively improving the user experience.

[0037] In one embodiment, as Figure 2 shown, the transmission mechanism 300 is provided with a first convex column 3211 and a second convex column 3212 that respectively extend along the width direction of the cabinet door 100. Moreover, the first convex column 3211 and the second convex column 3212 are arranged at intervals, and the distance between the center lines of the first convex column 3211 and the second convex column 3212 is defined as a preset distance Z.

[0038] When the driving mechanism 400 is in the first operating stage, the moving direction of the cabinet door 100 is the preset direction, which is represented by S in the figure. The cabinet body 200 is provided with a first linear sliding groove 221 and a second linear sliding groove 222 that respectively extend along the preset direction and are collinear. Among them, the second linear sliding groove 222 is connected to one end of the first linear sliding groove 221 close to the cabinet door 100. Moreover, the length X of the first linear sliding groove 221 along the preset direction, the length Y of the second linear sliding groove 222 along the preset direction, the radius R1 of the first convex column 3211, and the radius R2 of the second convex column 3212 satisfy X≤Y = Z + R1 + R2.

[0039] Define the end of the second linear sliding groove 222 close to the cabinet door 100 as the fulcrum end 2221. The cabinet body 200 is provided with an arc sliding groove 223, and the arc sliding groove 223 is an arc structure corresponding to a circle with the fulcrum end 2221 as the center and the preset distance as the radius. Moreover, the arc sliding groove 223 is connected to the connection point of the first linear sliding groove 221 and the second linear sliding groove 222 (forming an approximate inverted U-shaped three-way structure).

[0040] It can be understood that when the cabinet door 100 is opened upward, one end of the arc sliding groove 223 is connected to the second linear sliding groove 222, and the other end of the arc sliding groove 223 extends downward and towards the direction close to the cabinet door 100;

[0041] When the cabinet door 100 is opened downward, one end of the arc sliding groove 223 is connected to the second linear sliding groove 222, and the other end of the arc sliding groove 223 extends upward and towards the direction close to the cabinet door 100.

[0042] Specifically, the radian corresponding to the arc sliding groove 223 is equal to the preset angle. That is to say, the arc sliding groove 223 is designed with the same radian as the number of preset angles that the cabinet door 100 needs to rotate.

[0043] Thus, when the driving mechanism 400 is in the first operating stage, the first convex column 3211 is located within the first linear sliding groove 221 and can slidably cooperate with the first linear sliding groove 221 along a preset direction. The second convex column 3212 is located within the second linear sliding groove 222 and can slidably cooperate with the second linear sliding groove 222 along a preset direction, so that the transmission mechanism 300 can drive the cabinet door 100 to move a preset distance along a preset direction.

[0044] When the driving mechanism 400 is in the second operating stage, the second convex column 3212 is rotatably limited at the fulcrum end 2221, and the first convex column 3211 and the arc-shaped sliding groove 223 can slidably cooperate along the extension direction of the arc-shaped sliding groove 223, so that the transmission mechanism 300 can drive the cabinet door 100 to rotate a preset angle around the fulcrum end 2221.

[0045] It should be noted that, for the convenience of rotation, in one embodiment, the second convex column 3212 is cylindrical.

[0046] In other embodiments, the second convex column 3212 can also be a polygonal column.

[0047] Since the first convex column 3211 does not need to rotate, the first convex column 3211 can be cylindrical, prismatic or other shapes, which are not listed one by one here.

[0048] With such a setting, the arc-shaped sliding groove 223, the first linear sliding groove 221 and the second linear sliding groove 222 form an approximately inverted-J-shaped bifurcated structure. The part of the transmission mechanism 300 provided with the first convex column 3211 and the second convex column 3212 will first move linearly along a preset direction to make the cabinet door 100 away from the cabinet body 200. After that, the second convex column 3212 reaches the position of the fulcrum end 2221 and cannot continue to move along the preset direction. Then, the first convex column 3211 starts to turn into the arc-shaped sliding groove 223 and rotates around the second convex column 3212. At this time, the transmission mechanism 300 uses its own rotation to drive the cabinet door 100 to rotate, realizing the opening of the cabinet door 100.

[0049] Moreover, it can be understood that the closing process of the cabinet door 100 is opposite to the above process, which will not be elaborated here.

[0050] Obviously, with such a setting, by designing an inverted-J-shaped track groove (including the arc-shaped sliding groove 223, the first linear sliding groove 221 and the second linear sliding groove 222) and cleverly performing a combined linear and rotational movement cooperation with the first convex column 3211 and the second convex column 3212, the transmission mechanism 300 can achieve multiple combined movements of the cabinet door 100 with one action, greatly improving the transmission efficiency of the door structure.

[0051] However, the present invention is not limited thereto. In other embodiments, a plurality of driving mechanisms 400 may drive the transmission mechanism 300 in the first operation phase and the second operation phase respectively.

[0052] In one embodiment, if Figure 2 As shown, the cabinet 200 includes a main body 210, a guide plate 220, and a mounting bracket 230. The arcuate slide 223, the first linear slide 221, and the second linear slide 222 are all provided on the guide plate 220. The guide plate 220 is provided within the main body 210 and is spaced apart from the side wall of the main body 210 so that the transmission mechanism 300 can be provided between the guide plate 220 and the side wall of the main body 210. The mounting bracket 230 is fixedly connected to the main body 210, and the drive mechanism 400 and the transmission mechanism 300 can be mounted on the mounting bracket 230.

[0053] In one embodiment, if Figure 2 As shown, the transmission mechanism 300 includes a connecting rod assembly 310 and a slider assembly 320. One end of the connecting rod assembly 310 is connected to the output end of the driving mechanism 400, and the other end is hinged to the slider assembly 320. The driving mechanism 400 can apply torque to the slider assembly 320 through the connecting rod assembly 310, and the first boss 3211 and the second boss 3212 are both arranged on the slider assembly 320. The slider assembly 320 is fixedly connected to the cabinet door 100 at one end away from the connecting rod assembly 310.

[0054] With such a configuration, in conjunction with the arc groove 223, the first linear groove 221 and the second linear groove 222, when the first boss 3211 and the second boss 3212 are respectively located in the first linear groove 221 and the second linear groove 222, the torque applied by the connecting rod assembly 310 to the slider assembly 320 will be converted into a linear thrust along a preset direction. When the second boss 3212 can no longer move in a straight line and the first boss 3211 turns into the arc groove 223 under the action of the torque, the torque applied by the connecting rod assembly 310 to the slider assembly 320 will drive the first boss 3211 to rotate.

[0055] Furthermore, in one embodiment, if Figure 2 As shown, the connecting rod assembly 310 includes a first connecting rod 311 and a second connecting rod 312. One end of the first connecting rod 311 is fixedly connected to the output end of the driving mechanism 400, and the other end is hinged to the second connecting rod 312. The end of the second connecting rod 312 away from the first connecting rod 311 is hinged to the slider assembly 320.

[0056] With such an arrangement, the structure of the connecting rod assembly 310 is relatively simple, which is beneficial to the installation and operation of the entire driving mechanism 400 and can reduce the failure rate of the door structure during use.

[0057] However, the present invention is not limited thereto. In other embodiments, the connecting rod assembly 310 may further include a greater number of rods to achieve more precise torque transmission.

[0058] Furthermore, in one embodiment, if Figure 2 As shown, the slider assembly 320 includes a transmission block 321 and a connecting block 322, the first boss 3211 and the second boss 3212 are both arranged on the transmission block 321, one end of the transmission block 321 is hinged to the connecting rod assembly 310 (specifically the second connecting rod 312), and the other end is fixedly connected to the connecting block 322, and the connecting block 322 is fixedly connected to the cabinet door 100 at one end away from the transmission block 321.

[0059] In this way, the slider assembly 320 can be dispersedly arranged to adapt to the shapes of the cabinet door 100 and the cabinet body 200 .

[0060] Specifically, the transmission block 321 and the connection block 322 can be integrally bent and formed, or can be detachably connected via fasteners.

[0061] In one embodiment, if Figure 2 As shown, the driving mechanism 400 is a motor component, and the transmission mechanism 300 also includes a reduction gear assembly 330. The output end of the driving mechanism 400 is connected to the connecting rod assembly 310 through the reduction gear assembly 330 so that the rotational angular velocity of the connecting rod assembly 310 is less than the rotational angular velocity of the output end of the driving mechanism 400.

[0062] Such an arrangement is beneficial to reducing the opening and closing speed of the cabinet door 100.

[0063] Specifically, if Figure 2 As shown, the reduction gear assembly 330 includes a first reduction gear 331 and a second reduction gear 332 that are meshed together. The first reduction gear 331 is fixedly connected to the output end of the driving mechanism 400, and the first reduction gear 331 and the output end of the driving mechanism 400 are coaxially arranged. The second reduction gear 332 is fixedly connected to the connecting rod assembly 310 (specifically the first connecting rod 311), and the rotation radius of the second reduction gear 332 is greater than the rotation radius of the first reduction gear 331.

[0064] In one embodiment, if Figure 2 and Figure 3 As shown, the transmission mechanism 300 includes an active mechanism 340, a linkage mechanism 350 and a transmission rod 360. The active mechanism 340 and the linkage mechanism 350 are connected to both ends of the cabinet door 100 along the width direction of the cabinet door 100. The active mechanism 340 is connected to the output end of the driving mechanism 400. The two ends of the transmission rod 360 are respectively connected to the active mechanism 340 and the linkage mechanism 350, so that the driving mechanism 400 can drive the linkage mechanism 350 to move through the active mechanism 340 and the transmission rod 360 in turn.

[0065] Such an arrangement makes the force distribution of the transmission mechanism 300 on the cabinet door 100 more balanced, which is beneficial to improving the movement stability of the cabinet door 100.

[0066] The present application also provides a disinfection cabinet, which includes the door structure described in any one of the above embodiments.
