Description

Technical Field

[0001] This application relates to the field of warehouse door technology, specifically an automatic warehouse door. Background Technology

[0002] A warehouse is a collective term for the places and buildings used to store goods, including production materials, tools, or other property, as well as the places and buildings used to safeguard their quantity and value. From a socio-economic perspective, warehouses are indispensable in both the production and distribution of goods sectors. Warehouses used for storing goods such as grain and military machinery generally have higher requirements for airtightness and moisture protection.

[0003] Currently, many manufacturers at home and abroad produce warehouse doors with moisture-proof and sealing functions. However, the opening and closing of warehouse doors on the market, as well as the locking of the sealing mechanism, are entirely done manually. The degree of automation is low, and the operation is complicated and inefficient when storing and retrieving goods.

[0037] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] In the description of this application, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific scope of protection of this application. The terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "comprising" and "having," and any variations thereof, in the specification and claims of this application, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0039] Reference Figure 1 and Figure 2 One embodiment of this application provides an automatic warehouse door, including a door frame 1, a door leaf 2, and a seal. The door leaf 2 is rotatably mounted on the door frame 1, and the seal is disposed between the door frame 1 and the door leaf 2. The rotatable mounting method between the door leaf 2 and the door frame 1 is existing technology, such as using a hinge 3 (e.g., Figure 2 (as shown); in addition, the sealing element itself and its installation method are also existing technologies, such as rubber sealing strips, which are embedded in the door leaf 2 or the door frame 1.

[0040] Reference Figure 3 The automatic warehouse door also includes an opening mechanism 4 and a locking mechanism 5. The opening mechanism 4 is located on the door frame 1 and is used to drive the door leaf 2 to open or close. The locking mechanism 5 is located between the door frame 1 and the door leaf 2. When the opening mechanism 4 drives the door leaf 2 to close, the locking mechanism 5 forces the door leaf 2 and the door frame 1 to press against each other and seal. When the automatic warehouse door is in operation, when the locking mechanism 5 is released, the opening mechanism 4 can automatically control the opening and closing of the door leaf 2, realizing the automatic opening and closing of the warehouse door. Moreover, when the opening mechanism 4 drives the door leaf 2 to close, the locking mechanism 5 locks the door leaf 2 and the door frame 1, thereby pressing the door leaf 2 and the door frame 1 against each other and sealing them. The seal deforms under pressure, thus fully filling the gap between the door leaf 2 and the door frame 1, achieving automatic moisture-proof sealing of the warehouse door. The opening, closing, and sealing of this automatic warehouse door can all be automatically operated, with a high degree of automation, making it easier and more efficient to store and retrieve goods.

[0041] Reference Figure 4 and Figure 5 In some embodiments of this application, the door opening mechanism 4 includes a first drive assembly 41, a drive arm 42, and a connecting arm 43. One end of the connecting arm 43 is hinged to the door leaf 2, and the other end of the connecting arm 43 is hinged to one end of the drive arm 42. The other end of the drive arm 42 is disposed on the first drive assembly 41. The first drive assembly 41 is disposed on the door frame 1 and is used to drive the drive arm 42 to rotate, thereby driving the door leaf 2 to open or close via the connecting arm 43. By controlling the start and stop of the first drive assembly 41, the drive arm 42 can be driven to rotate. After the drive arm 42 rotates, the end of the drive arm 42 away from the first drive assembly 41 will apply a pushing or pulling force to the door leaf 2 via the connecting arm 43, thereby forcing the door leaf 2 to open or close. Preferably, the connecting arm 43 adopts an arc-shaped structure. When the door leaf 2 is opened 180°, the arc-shaped connecting arm 43 can avoid mutual interference between the connecting arm 43 and the door leaf 2, and between the connecting arm 43 and the door frame 1.

[0042] Reference Figures 4 to 6In some embodiments of this application, the drive arm 42 has a shaft hole 421 at one end away from the connecting arm 43; the first drive assembly 41 includes a first motor 411, a transmission shaft 412, and a linkage 413; the first motor 411 is disposed on the door frame 1, and the first motor 411 is used to drive the transmission shaft 412 to rotate, and the transmission shaft 412 is coaxially and rotatably disposed in the shaft hole 421; the linkage 413 is disposed on the transmission shaft 412, and the linkage 413 is used to lock the transmission shaft 412 and the drive arm 42, thereby restricting relative rotation between the transmission shaft 412 and the shaft hole 421. When the transmission shaft 412 and the drive arm 42 are locked by the linkage 413, the drive arm 42 can be driven to rotate by controlling the start and stop of the first drive assembly 41, thereby realizing the automatic opening and closing of the door 2. However, when the locking mechanism 5 locks the door leaf 2 to the door frame 1, the first motor 411 has actually stopped working, but the locking mechanism 5 will continue to apply force to the door leaf 2. At this time, if the linkage 413 is still in the locked state, the force of the locking mechanism 5 on the door leaf 2 will sequentially drive the transmission shaft 412 and the first motor 411 in the opposite direction through the connecting arm 43 and the drive arm 42. This will result in the locking mechanism 5 applying a lower clamping force to the door leaf 2, thus requiring the locking mechanism 5 to apply a greater clamping force to the door leaf 2, resulting in greater energy consumption. In addition, a brake device is usually installed on the first motor 411. When the first motor 411 stops working, the brake device will start working to prevent the door leaf 2 from continuing to rotate. In this case, if the linkage 413 is always in the locked state, interference will occur between the locking mechanism 5 and the brake device when the locking mechanism 5 applies clamping force to the door leaf 2. Therefore, during the process of the locking mechanism 5 pressing the door leaf 2, the linkage 413 can be controlled to unlock, thereby releasing the restriction between the transmission shaft 412 and the shaft hole 421, so that the transmission shaft 412 and the shaft hole 421 (i.e., the drive arm 42) can rotate relative to each other, which can reduce the energy consumption of the locking mechanism 5 and avoid interference with the braking device.

[0043] Reference Figure 7 In some embodiments of this application, the side of the door frame 1 is provided with at least two locking grooves 11; the locking mechanism 5 includes a second drive assembly 51, a connecting rod 52, and a plurality of knots 53; each knot 53 is rotatably disposed at the edge of the door leaf 2 at intervals in the upper and lower or left and right, and one end of each knot 53 is hinged to the connecting rod 52; the second drive assembly 51 is disposed on the door leaf 2, and the second drive assembly 51 is used to drive one of the knots 53 to rotate, thereby driving the remaining knots 53 to rotate synchronously through the connecting rod 52; when the end of each knot 53 away from the connecting rod 52 is inserted into the corresponding locking groove 11, the door leaf 2 and the door frame 1 press against each other to form a seal. Figure 7As shown, when one of the clamp heads 53 is driven to rotate by the second drive assembly 51, the other clamp heads 53 will also rotate synchronously under the action of the connecting rod 52. That is to say, multiple clamp heads 53 on the same side of the door leaf 2 can be driven to rotate synchronously by one drive system to achieve simultaneous locking and unlocking. The structure is simple and the cost is lower. When each clamp head 53 rotates to insert into the corresponding locking groove 11, the door leaf 2 and the door frame 1 can be locked together, so that the door leaf 2 and the door frame 1 can clamp the sealing element together to achieve the moisture-proof sealing function.

[0044] Reference Figure 8 In some embodiments of this application, the second drive assembly 51 includes a second motor 511, a first gear 512, a second gear 513, a third gear 514, a fourth gear 515, a fixing frame 516, a fixing shaft 517, and bolts 518. The second motor 511 and the fixing frame 516 are both disposed on the door leaf 2. The first gear 512 is installed at the output end of the second motor 511. The second gear 513 and the third gear 514 are rotatably mounted on the fixing frame 516 through the fixing shaft 517. The second gear 513 and the third gear 514 are locked together by bolts 518. The fourth gear 515 is coaxially disposed on one of the clamps 53. The first gear 512, the second gear 513, the third gear 514, and the fourth gear 515 mesh sequentially. Therefore, after the second motor 511 is started, the corresponding clamp 53 can be driven to rotate.

[0045] Reference Figure 9In some embodiments of this application, a first inclined surface 531 is provided between the end face of the clamp head 53 away from the connecting rod 52 and the side facing the door leaf 2. If the first inclined surface 531 is not provided, when the clamp head 53 is inserted into the corresponding locking groove 11, in order to achieve the mutual clamping and sealing of the door leaf 2 and the door frame 1, the door leaf 2 needs to be fully closed by the door opening mechanism 4 (i.e., the door leaf 2 is temporarily subjected to a sufficiently large clamping force by the door opening mechanism 4) so ​​that the door leaf 2 and the door frame 1 are clamped and sealed. At this time, the second drive assembly 51 is activated to drive the clamp head 53 to insert into the corresponding locking groove 11, and the gap between the side of the clamp head 53 facing the door leaf 2 and the corresponding inner sidewall of the locking groove 11 should not be too large. The door opening mechanism 4 can only be closed after the clamp head 53 locks the door leaf 2 and the door frame 1. Although this method can also achieve the locking purpose, it has extremely high requirements for the control system, position accuracy, installation accuracy, etc., and is prone to failure during use. With the first inclined surface 531 in place, the door opening mechanism 4 only needs to close the door leaf 2 (i.e., it does not need to be fully closed). When the clamp head 53 rotates to the point where it is about to enter the locking groove 11, the first inclined surface 531 first contacts the inner wall of the locking groove 11. As the clamp head 53 continues to rotate, the inner wall of the locking groove 11 will exert a force on the clamp head 53 through the first inclined surface 531. This force forces the door leaf 2 to be fully closed, thereby reducing the requirements for the control system, position accuracy, installation accuracy, etc.

[0046] Reference Figure 9 In some embodiments of this application, a second inclined surface 532 is provided between the end face of the tie head 53 away from the connecting rod 52 and the side facing away from the door leaf 2. Under the action of the second inclined surface 532, during the process of inserting the tie head 53 into the locking groove 11, the side face of the tie head 53 facing away from the door leaf 2 is less likely to hit the inner wall of the locking groove 11, thereby improving the stability of the tie head 53 when inserted into the locking groove 11.

[0047] Reference Figures 10 to 13In some embodiments of this application, at least one of the left and right sides of the door leaf 2 is provided with a plurality of knots 53 spaced apart in the vertical direction, and at least one of the upper and lower sides of the door leaf 2 is provided with a plurality of knots 53 spaced apart in the horizontal direction, and each knot 53 located on the same side of the door leaf 2 is hinged to the same connecting rod 52; the locking mechanism 5 also includes a transmission frame 54 and a transmission arm 55, the transmission frame 54 is disposed on a knot 53 in the horizontal or vertical direction, and correspondingly, one end of the transmission arm 55 is hinged to a hinge shaft 1 between a knot 53 in the vertical or horizontal direction and the corresponding connecting rod 52. 00 (i.e., when the transmission frame 54 is set on a knot 53 in the left-right direction, one end of the transmission arm 55 is hinged to a knot 53 in the up-down direction; when the transmission frame 54 is set on a knot 53 in the up-down direction, one end of the transmission arm 55 is hinged to a knot 53 in the left-right direction), and the other end of the transmission arm 55 is hinged to the transmission frame 54; when the second drive assembly 51 drives one of the knots 53 to rotate, the corresponding connecting rod 52 drives the transmission frame 54 to rotate through the transmission arm 55, thereby forcing the knot 53 connected to the transmission frame 54 to rotate. Since a single linkage 52 can only drive multiple latches 53 on the same side of the door leaf 2 to rotate simultaneously, when latches 53 are provided on both adjacent sides of the door leaf 2, the latches 53 on adjacent sides can be linked through the transmission frame 54 and the transmission arm 55. This achieves linkage between two adjacent linkages 52, allowing a single drive system to simultaneously drive multiple latches 53 on different sides of the door leaf 2 to rotate, thus achieving simultaneous locking and unlocking. This results in a simple structure and lower cost. For example, when multiple latches 53 are provided on all four sides of the door leaf 2 (such as...) Figure 10 As shown), when the second drive assembly 51 drives one of the tie heads 53 on the left side of the door leaf 2 to rotate counterclockwise, the tie head 53 will drive the corresponding connecting rod 52 to drive all the tie heads 53 on the left side of the door leaf 2 to rotate counterclockwise simultaneously. The connecting rod 52, through the corresponding transmission arm 55, drives the transmission frame 54 and the tie heads 53 connected to the transmission frame 54 (i.e., the upper tie head 53) to rotate clockwise (as shown). Figure 11 As shown), this causes each of the tie heads 53 on the upper side of the door leaf 2 to rotate clockwise synchronously; at the same time, the upper connecting rod 52 will drive the corresponding tie head 53 on the right side to rotate counterclockwise through the transmission arm 55 and transmission frame 54 on the right side (as shown). Figure 13 As shown), this drives the various knots 53 on the right side of the door leaf 2 to rotate counterclockwise synchronously via the connecting rod 52 on the right side; in addition, the connecting rod 52 on the left side drives the corresponding knots 53 on the lower side to rotate clockwise via the lower transmission arm 55 and the transmission frame 54 (as shown). Figure 12 As shown), the lower connecting rod 52 drives the various knots 53 on the lower side of the door leaf 2 to rotate clockwise synchronously.

[0048] It should be noted that this application does not limit the specific structure of the linkage 413 described above. Only two specific structures are provided below for reference, see Embodiment 1 and Embodiment 2 for details.

[0049] Example 1: Refer to Figures 4 to 6 The linkage 413 is an electromagnetic clutch. By controlling the engagement and disengagement of the electromagnetic clutch, locking and unlocking between the drive shaft 412 and the shaft hole 421 can be achieved. The electromagnetic clutch itself and its installation and control methods are existing technologies and will not be described in detail here. A position sensor is installed to detect the actual position of the door leaf 2. When the door leaf 2 is detected to be closed and the locking mechanism 5 is activated, the electromagnetic clutch is de-energized in a timely manner, thereby allowing relative rotation between the drive shaft 412 and the shaft hole 421.

[0050] Example 2: Refer to Figures 14 to 17 The drive shaft 412 has an axially oriented channel 4121 on its end face near the door leaf 2, and a through hole 4122 is radially penetrating the inner annular surface of the channel 4121; the drive arm 42 has an insertion hole 422 along the axial direction of the shaft hole 421; the linkage 413 includes a push rod 4131, a sliding sleeve 4132, a pin 4133, a pin 4134, and an elastic element 4135; the push rod 4131 is axially slidably disposed in the channel 4121, and the sliding sleeve 4132 is axially slidably disposed in the channel 4121. A sliding sleeve 4133 is mounted on the drive shaft 412; a pin 4133 is disposed between the push rod 4131 and the sliding sleeve 4132, and the pin 4133 is slidably connected to the through hole 4122 along the axial direction of the drive shaft 412; one end of the pin 4134 is fixed to the sliding sleeve 4132, and an elastic element 4135 is used to force the sliding sleeve 4132 to slide until the other end of the pin 4134 is inserted into the insertion hole 422, thereby restricting relative rotation between the drive shaft 412 and the shaft hole 421. Figure 16 and Figure 17As shown, when an upward force is applied to the push rod 4131, the push rod 4131 drives the sliding sleeve 4132 to slide upward via the pin 4133. The sliding fit between the pin 4133 and the through hole 4122 restricts relative rotation between the push rod 4131, the drive shaft 412, and the sliding sleeve 4132. After the sliding sleeve 4132 slides upward, the lower end of the pin 4134 disengages from the insertion hole 422, thereby releasing the lock between the drive shaft 412 and the shaft hole 421 (i.e., the drive arm 42), allowing relative rotation between the drive shaft 412 and the shaft hole 421 (i.e., the drive arm 42). Simultaneously, when the force applied to the push rod 4131 disappears, under the action of the elastic element 4135, the push rod 4131, the sliding sleeve 4132, the pin 4134, and the pin 4133 slide downward simultaneously, causing the pin 4134 to insert into the insertion hole 422, thus achieving the locking between the drive shaft 412 and the drive arm 42. To ensure that the pin 4134 can be accurately inserted into the socket 422, the lower end of the pin 4134 and / or the upper end of the socket 422 can be chamfered or rounded, which facilitates the insertion of the pin 4134. It should be noted that the elastic element 4135 can be sleeved on the outside of the drive shaft 412 to apply a restoring force to the sliding sleeve 4132, or it can be located inside the channel 4121 to apply a restoring force to the push rod 4131. Furthermore, the rotatable mounting method between the drive shaft 412 and the shaft hole 421 can be achieved through the bearing 200.

[0051] Reference Figure 14 , Figure 18 as well as Figure 19 In embodiment two, the side of the door frame 1 is provided with at least two locking grooves 11; the locking mechanism 5 includes a second drive assembly 51, a connecting rod 52, and a plurality of locking heads 53; each locking head 53 is rotatably disposed at the edge of the door leaf 2 with vertical spacing, and one end of each locking head 53 is hinged to the connecting rod 52; the second drive assembly 51 is disposed on the door leaf 2, and the second drive assembly 51 is used to drive one of the locking heads 53 to rotate, thereby driving the remaining locking heads 53 to rotate synchronously through the connecting rod 52; when the end of each locking head 53 away from the connecting rod 52 is inserted into the corresponding locking groove 11, the door... The door leaf 2 and the door frame 1 are pressed together with a sealing element; the linkage 413 also includes a lever 4136, which is rotatably mounted on the door leaf 2; one end of the lever 4136 is provided with a strip hole 4137, which is hinged to the hinge shaft 100 between the tie head 53 and the connecting rod 52; when the tie head 53 rotates, the hinge shaft 100 slides in the strip hole 4137, causing the lever 4136 to rotate; when the tie head 53 rotates to insert into the locking groove 11, the end of the lever 4136 away from the strip hole 4137 pushes the push rod 4131, causing the pin 4134 to separate from the insertion hole 422. Figure 18 and Figure 19As shown, when the second drive assembly 51 drives the clamp 53 to rotate counterclockwise (i.e., the locking mechanism 5 changes from the locked state to the unlocked state), the hinge shaft 100 applies a force to the lever 4136 through the strip hole 4137, thereby forcing the lever 4136 to rotate clockwise. At this time, the end of the lever 4136 away from the strip hole 4137 will gradually separate from the lower end of the push rod 4131, that is, the upward force acting on the push rod 4131 disappears, and the push rod 4131 automatically resets downward under the action of the elastic element 4135, thus realizing the automatic start of the linkage 413. Conversely, when the locking mechanism 5 changes from the unlocked state to the locked state, the end of the lever 4136 away from the strip hole 4137 will gradually approach the lower end of the push rod 4131 until an upward force is applied to the push rod 4131, thereby realizing the automatic closing of the linkage 413. It should be noted that when the first inclined surface 531 is provided, the lever 4136 should have already triggered the push rod 4131 at the instant or before the inner wall of the locking groove 11 begins to exert force on the first inclined surface 531. As can be seen from the above, the linkage 413 of this structure is achieved through mechanical linkage. Compared to an electromagnetic clutch, it does not require a corresponding control circuit, is more stable and reliable, and eliminates the need for a sensor to detect the position of the door leaf 2, resulting in lower costs.

[0052] Reference Figures 14 to 16 In Embodiment 2, in order to seal the sliding sleeve 4132, pin 4134, elastic element 4135 and other structures, the linkage 413 also includes a housing 4138 and an end cap 4139. The housing 4138 and the end cap 4139 are both sleeved on the outside of the drive shaft 412. The end of the housing 4138 near the drive arm 42 is an open structure. This open structure is sealed by the end cap 4139. The housing 4138 and the end cap 4139 form a receiving cavity to seal the sliding sleeve 4132, pin 4134, elastic element 4135 and other structures. At the same time, the end cap 4139 is provided with a clearance hole for the pin 4134 to pass through, so it will not affect the connection between the pin 4134 and the insertion hole 422.
