Description

Technical Field

[0001] The present invention relates to the technical field of top cover opening and closing, and in particular to an automatic opening and closing storage device and an opening and closing method. Background Art

[0002] In the fields of logistics services, radiotherapy, etc., boxes are often used to store goods or dangerous goods to achieve cargo turnover and shielding of dangerous goods.

[0003] To prevent the top cover of the box from being accidentally opened, the utility model patent application number CN202120293720.3 discloses a radiation-proof lead can. The can body (i.e., the box) and the lid (i.e., the top cover) are equipped with a lock buckle on one side and a snap buckle on the other side. When the lid is closed on the can body, the lock buckle and the snap buckle are connected to lock the can lid. However, in this solution, connecting or disconnecting the lock buckle and the snap buckle requires manual operation, which is very cumbersome and greatly affects the opening and closing efficiency of the can lid.

[0004] In order to improve the opening and closing efficiency of the can lid, an automatic opening and closing lid mechanism came into being. For example, the invention patent with application number CN202011400885.6 discloses a fully automatic opening and closing lid mechanism for a packaging box, which includes a mounting frame, an unlocking buckle toggle mechanism, a lock buckle closing mechanism and a suction cup; when the box lid needs to be opened, the unlocking buckle toggle mechanism must first be driven down as a whole by the main lifting cylinder, so that the unpacking toggle plate of the unlocking toggle mechanism enters the gap between the upper lock buckle and the box lid, and the toggle cylinder push rod drives the unpacking toggle plate to swing outward to push the upper lock buckle to flip outward; then, the downward pressure cylinder push rod in the lock buckle closing mechanism extends to drive the downward pressure roller to descend and press the upper lock buckle to a horizontal position, and then the lower lock buckle driving cylinder on the lower side of the lock buckle closing mechanism absorbs the lower lock buckle through the magnetic buckle and drives the lower lock buckle to move outward, After unlocking is completed, the box lid is sucked and moved to another position by the suction cup; when the box lid needs to be closed, the suction cup sucks and moves the box lid to the top of the box body, and the lower lock buckle driving cylinder on the lower side of the lock closing mechanism adsorbs the lower lock buckle through the magnetic buckle and drives the lower lock buckle to move inward so that it fits the box body, and the upper lock buckle closing cylinder retracts to drive the upper lock buckle closing roller to flip upward to push the upper lock buckle to flip inward until it fits the box lid, completing the lock closure of the box lid; although this patent can realize automatic unlocking, automatic locking and automatic opening and closing of the box lid, its unlocking and locking steps are complicated, which not only affects the overall opening and closing efficiency of the box lid, but also increases the structural complexity of the entire automatic opening and closing mechanism, and has the disadvantages of high cost and low reliability.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "two" quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0046] The present application provides an automatic opening and closing storage device, such as Figure 1 As shown, it includes a box body 1, a top cover 2 and an opening and closing drive device; wherein, a plurality of locking devices 3 are provided on the top cover 2, and a connecting end 11 is provided on the box body 1, and the locking devices 3 can be locked and installed on the connecting end 11; the opening and closing drive device includes an unlocking plate 41, and the unlocking and locking of each locking device 3 and the opening and closing of the top cover 2 are realized by the movement of the unlocking plate 41.

[0047] like Figure 1 As shown, the box body 1 and the top cover 2 are arranged separately. When the top cover 2 is covered on the top opening of the box body 1, each locking device 3 can cooperate with the connecting end 11 on the box body 1 to limit the position of the top cover 2 covered on the box body 1, so that the top cover 2 is in a closed and locked state; when the box body 1 needs to be opened, it is only necessary to unlock each locking device 3, so that the top cover 2 is in an unlocked state, and then lift the top cover 2 in the unlocked state away from the box body 1.

[0048] It should be noted that the box body 1 can be of various shapes such as a square structure or a cylindrical structure, which is not limited thereto. In the present embodiment, the box body 1 is preferably a square structure.

[0049] It should be noted that the materials of the box body 1 and the top cover 2 need to be determined according to the usage scenario and are not limited to this.

[0050] In this embodiment, the box 1 is used to accommodate radioactive sources such as target segments; at this time, the materials of the box 1 and the top cover 2 include radiation protection materials to play a radiation shielding role, thereby preventing the rays released by the radioactive source from damaging the human body.

[0051] It should be noted that the radiation protection material includes but is not limited to lead or radiation-proof glass; in this embodiment, the radiation protection material is preferably lead.

[0052] It is understandable that the box body 1 and the top cover 2 can be made of lead alone, or can be made of lead and radiation-proof activation materials such as low-activation steel, without limitation.

[0053] Because lead is a high-density, toxic heavy metal, to reduce the weight of the housing 1 and minimize its harmful effects on the human body, the housing 1 preferably adopts a double-layer structure. Specifically, the housing 1 comprises an inner lead layer and an outer radiation-protective active layer. The radiation-protective active layer can be made of, but is not limited to, low-activation steel (such as 101 stainless steel), high-density polyethylene, or a boron-containing polyethylene composite material. In this embodiment, the radiation-protective active layer is 101 stainless steel.

[0054] In a preferred embodiment, if Figure 2 and Figure 3 As shown, the top cover 2 is a boss structure that protrudes downward in the middle; the protruding portion cooperates with the top opening of the box body 1, and the protruding portion is composed of radiation protection materials such as lead; the edge of the boss is placed on the top of the box body 1 to close the opening, and the edge of the boss is composed of low-activation steel such as 101 stainless steel; such a setting can not only reduce the weight of the top cover 2, but also avoid lead exposure that may damage the human body, taking into account both weight and safety.

[0055] In addition, when the top cover 2 is closed on the box body 1, the protruding portion of the top cover 2 is plugged into the top opening of the box body 1 to limit the horizontal position of the top cover 2 on the box body 1; the protruding portion has a certain taper to facilitate alignment and installation; in this way, the top cover 2 can only be opened or closed by lifting the box body 1, thereby preventing the top cover 2 from sliding horizontally off the box body 1 in the closed state.

[0056] like Figure 1 and Figure 2 As shown, the multiple locking devices 3 involved in this application include a retracting member 31a and / or a pop-up member 31b, and each retracting member 31a and / or pop-up member 31b is located at a different position of the top cover 2 to cooperate in achieving position locking of the top cover 2 in the closed state.

[0057] In order to facilitate automatic locking of the top cover 2, the retracting member 31a and the ejecting member 31b are both sliding elastic locking devices.

[0058] Specifically, if Figure 4 、 Figure 5 、 Figure 7As shown, the contraction member 31a includes a contraction rod 311a, a contraction head 312a, a contraction stop head 313a and a contraction elastic member 314a; the connecting end 11 includes a connecting plate 11a, and the connecting plate 11a is provided with a locking groove 111a that cooperates with the contraction head 312a; a base 21 is provided above the top cover 2, and the contraction rod 311a of the contraction member 31a is slidably penetrated in the base 21 along the first horizontal direction, and the contraction head 312a and the contraction stop head 313a of the contraction member 31a are respectively aligned with the corresponding contraction rod 311a. The two ends are connected to prevent the shrinking piece 31a from separating from the corresponding base 21; the shrinking elastic piece 314a is a tension spring arranged between the shrinking head 312a and the base 21, or the shrinking elastic piece 314a is a pre-stressed elastic piece arranged between the shrinking stop head 313a and the base 21, and the pre-stressed elastic piece is a compression spring or a pre-stressed elastic sleeve, wherein the pre-stressed elastic sleeve is made of elastic materials such as rubber; in this embodiment, the shrinking head 312a and the shrinking stop head 313a of the shrinking piece 31a are always located outside the corresponding base 21.

[0059] In the free state (i.e., when not subject to external force), the contraction elastic member 314a drives the contraction head 312a of the contraction member 31a to enter the corresponding locking groove 111a for engagement. At this time, the contraction head 312a is in the locked position. When unlocking is required, it is only necessary to apply external force to the contraction member 31a so that the contraction head 312a on the contraction member 31a passes over the corresponding locking groove 111a to reach the unlocking position. At this time, the contraction rod 311a of the contraction member 31a is located in the corresponding locking groove 111a (as shown in FIG. Figure 10 shown).

[0060] In a preferred embodiment, if Figure 5 As shown, the shrinking head 312a has a tapered structure. When the shrinking head 312a enters the locking groove 111a and engages under the action of the shrinking elastic member 314a, the tapered structure of the shrinking head 312a can be in close contact with the locking groove 111a to achieve circumferential limitation, thereby ensuring the stability of locking.

[0061] In addition, in order to smoothly open the top cover 2, as Figure 7 and Figure 8 As shown, the connecting plate 11a is provided with an avoidance opening 112a connected to the locking slot 111a; the avoidance opening 112a is located above the corresponding locking slot 111a and is connected to the top of the connecting plate 11a to form an opening structure; when the shrinking head 312a on the shrinking piece 31a is in the locked position, the shrinking head 312a on the shrinking piece 31a cannot cross the locking slot 111a and enter the avoidance opening 112a above, thereby ensuring the stability of the locking; when the shrinking head 312a on the shrinking piece 31a is in the unlocked position, the avoidance opening 112a is used to avoid the shrinking rod 311a on the corresponding shrinking piece 31a in the vertical direction, so that the shrinking rod 311a can smoothly enter and exit the corresponding locking slot 111a when the top cover 2 is opened and closed.

[0062] like Figure 4 、 Figure 6 and Figure 7 As shown, the ejection member 31b includes an ejection rod 311b, an ejection head 312b, an ejection stop head 313b and an ejection elastic member 314b; the connecting end 11 includes a connecting plate 11b, and the connecting plate 11b is provided with a locking groove 111b that cooperates with the ejection head 312b; the top cover 2 is provided with a base 21, the ejection rod 311 of the ejection member 31b is slidably arranged in the base 21 along the first horizontal direction, and the ejection head 312b and the ejection stop head 313b of the ejection member 31b are respectively connected to the corresponding The two ends of the pop-up rod 311b are connected; the pop-up elastic member 314b is a pre-stressed elastic member arranged between the pop-up head 312b and the base 21, and the pre-stressed elastic member is a compression spring or a pre-stressed elastic sleeve, wherein the pre-stressed elastic sleeve is made of elastic materials such as rubber; or, the pop-up elastic member 314b is a tension spring arranged between the pop-up stop head 313b and the base 21; in this embodiment, the pop-up head 312b and the pop-up stop head 313b on the pop-up member 31b are always located outside the corresponding base 21.

[0063] In the free state (i.e., when not subject to external force), the pop-up elastic member 314b drives the pop-up head 312b on the pop-up member 31b to enter the corresponding lock groove 111b for engagement. At this time, the pop-up head 312b on the pop-up member 31b is in the locked position; when unlocking is required, it is only necessary to apply external force to the pop-up member 31b so that the pop-up head 312b on the pop-up member 31b exits the corresponding lock groove 111b and reaches the unlocked position (e.g., Figure 11 As shown), at this time, the ejection member 31b is completely separated from the corresponding locking slot 111b, which facilitates the smooth opening and closing of the top cover 2.

[0064] In a preferred embodiment, if Figure 6 As shown, the pop-up head 312b has a tapered structure. When the pop-up head 312b enters the lock slot 111b and engages under the action of the pop-up elastic member 314b, the tapered structure of the pop-up head 312b can be in close contact with the lock slot 111b to achieve circumferential limitation, thereby ensuring the stability of the locking.

[0065] like Figure 1 and Figure 12 As shown, the opening and closing drive device involved in the present application includes a horizontal drive device 43 and a lifting drive device 5; wherein, the horizontal drive device 43 is used to drive the unlocking plate 41 to move back and forth along the first horizontal direction, so as to unlock or avoid each locking device 3 through the unlocking plate 41, so that the top cover 2 can switch between the unlocked state and the locked state; when the top cover 2 is in the unlocked state, the lifting drive device 5 can drive the top cover 2 to open and close automatically.

[0066] Preferably, the horizontal drive device 43 and the lifting drive device 5 are hydraulic cylinders or pneumatic cylinders, and the control components of the hydraulic cylinders or pneumatic cylinders are arranged in an area away from the hydraulic cylinders or pneumatic cylinders, and are connected to the hydraulic or pneumatic cylinders through flexible pipes. In this way, the control components of the entire automatic opening and closing storage device will be away from the radiation source to avoid radiation interference with the control components when the radiation source is placed in the box 1, resulting in errors during the operation of the automatic opening and closing storage device.

[0067] According to the structural form of the multiple locking devices 3 on the top cover 2, the opening and closing drive device involved in this application has the following embodiments. Example 1

[0068] When the multiple locking devices 3 on the top cover 1 are all contraction parts 31a, as shown in FIG. Figure 10 As shown, each contraction member 31a is arranged in a row along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; at this time, as shown in FIG. Figure 1 、 Figure 3 、 Figure 12 As shown, the lifting drive device 5 is installed on the horizontal drive device 43, and the lifting end of the lifting drive device 5 is connected to the unlocking plate 41; two guide members 22 are provided at the upper end of the top cover 2; each guide member 22 is connected to the top cover 2 to form a guide groove 223 extending along the first horizontal direction, and the two guide grooves 223 are combined to form a guide channel extending along the first horizontal direction; the unlocking plate 41 is detachably inserted into the guide channel formed by the two guide grooves 223 along the first horizontal direction.

[0069] Further, such as Figure 2 and Figure 3 As shown, the guide member 22 includes a support block 221 and a limit plate 222; wherein, the support block 221 is integrally formed with the top cover 2 or the support block 221 is mounted on the top cover 2 by bolts, and the limit plate 222 is detachably mounted on the support block 221 by bolts; in this way, only the limit plate 222 needs to be removed to have enough space for disassembly and assembly of each locking device 3, thereby improving the convenience of disassembly and assembly of the locking device 3.

[0070] Since the unlocking plate 41 can be detachably inserted into the two guide grooves 223, the opening and closing drive device composed of the unlocking plate 41, the lifting drive device 5 and the horizontal drive device 43 can realize the unlocking and opening and closing of each top cover 2 through the cooperation of the unlocking plate 41 and the guide groove 223, thereby effectively improving the versatility of the opening and closing drive device.

[0071] For ease of understanding, the following Figures 12 to 16 , the working principle of the automatic opening and closing storage device is explained:

[0072] When the opening and closing drive device composed of the unlocking plate 41, the lifting drive device 5 and the horizontal drive device 43 is used to unlock the top cover 2 on the opening and closing box body 1 (that is, when the top cover is in the open working state), the unlocking plate 41 of the opening and closing drive device must first be inserted into the two guide grooves 223 on the corresponding top cover 2; then, the horizontal drive device 43 is started to move the lifting drive device 5 and the unlocking plate 41 together in a straight line toward the retracting member 31a until the unlocking plate 41 in the two guide grooves 223 pushes each retracting member 31a to the unlocking position, thereby switching the top cover 2 to the unlocked state. The specific unlocking process is detailed in Figure 15 and Figure 16 .

[0073] Then, if Figure 13 As shown, the lifting drive device 5 is activated to move the unlocking plate 41 upward, and the unlocking plate 41 drives the unlocked top cover 2 to move upward to the open position through the guide member 22. During this process, the force analysis of the top cover assembly composed of the top cover 2 and the guide member 22 is as follows:

[0074]

[0075] in, N 1 is the supporting force of the unlocking plate 41 on the top cover assembly; G is the gravity of the top cover assembly; T is the sum of the elastic restoring forces exerted by the elastic members in each locking device 3 on the top cover assembly; F f1max It is the maximum static friction force exerted by the unlocking plate 41 on the top cover assembly.

[0076] Since the sum of the elastic restoring forces T exerted by the elastic members in each locking device 3 on the top cover assembly during the upward movement of the top cover 2 is always smaller than the maximum static friction force F exerted by the unlocking plate 41 on the top cover assembly, f1max Therefore, during the upward movement, the top cover 2 and the unlocking plate 41 remain relatively stationary to maintain the unlocked state.

[0077] Then, if Figure 1 As shown, the horizontal drive device 43 is started, so that the lifting drive device 5, the unlocking plate 41 and the top cover 2 supported above the unlocking plate 41 move together in the direction away from the retracting member 31a until the top cover 2 in the unlocked state is moved to the avoidance position to prevent the top cover 2 from occupying the space above the box body 1 and affecting the taking and placing of items.

[0078] When the unlocking plate 41 moves horizontally, the top cover assembly requires a corresponding acceleration to maintain relative stillness with the unlocking plate 41. At this time, the acceleration required by the top cover assembly is determined by the static friction force of the unlocking plate 41 on the top cover assembly. F f1 and the elastic restoring force T exerted by the elastic members in each locking device 3 on the top cover assembly; as long as the static friction force F f1 Does not exceed the maximum static friction Ff1max , the top cover 2 can remain relatively still with the unlocking plate 41, thereby achieving horizontal movement of the top cover assembly and the unlocking plate 41 together.

[0079] When the top cover 2 needs to be closed (i.e., in the top cover closed working state), the horizontal drive device 43 is started, so that the lifting drive device 5, the unlocking plate 41, and the top cover assembly supported above the unlocking plate 41 move together in the direction close to the box body 1, so as to move the unlocked top cover 2 to the open position (i.e., directly above the box body 1); at this time, the acceleration required by the top cover assembly is determined by the static friction force of the unlocking plate 41 on the top cover assembly. F f1 and the elastic restoring force T exerted by the elastic members in each locking device 3 on the top cover assembly; as long as the static friction force F f1 Does not exceed the maximum static friction F f1max , the top cover 2 can remain relatively still with the unlocking plate 41, thereby achieving horizontal movement of the top cover assembly and the unlocking plate 41 together.

[0080] Then, if Figure 14 As shown, the lifting drive device 5 is started to move the unlocking plate 41 and the top cover 2 downward together until the top cover 2 in the unlocked state is closed on the box body 1. During the descending process of the top cover 2, the sum of the elastic restoring forces T exerted by the elastic members of each locking device 3 on the top cover assembly is always less than the maximum static friction force F exerted by the unlocking plate 41 on the top cover assembly. f2max (The maximum static friction F here f2max (related to the supporting force N2 of the unlocking plate 41 on the top cover assembly), so the top cover assembly is always in a force balance state in the horizontal direction, effectively ensuring the relative stillness of the top cover 2 and the unlocking plate 41 in the unlocked state.

[0081] After the top cover 2 is closed on the housing 1, the lifting drive 5 drives the unlocking plate 41 downward a certain distance, disengaging the unlocking plate 41 from the stop plate 222. Next, the horizontal drive 43 is adjusted to move the lifting drive 5 and the unlocking plate 41 together away from the retracting members 31a, thereby withdrawing the unlocking plate 41 from the guide slot 223 of the top cover 2. During this process, each retracting member 31a, under the action of the corresponding retracting elastic member 314a, returns to the locked position, thus completing the locking of the top cover 2.

[0082] The present embodiment only controls the position of the unlocking plate 41 in the first horizontal direction through the horizontal driving device 43, so as to automatically complete the simultaneous unlocking and locking of each locking device 3 on the top cover 2. Compared with the traditional solution in which each locking device 3 is equipped with an unlocking component separately, the unlocking solution of the present embodiment has the advantages of simple structure, low control difficulty, and convenient and quick unlocking. In addition, the present embodiment can detachably insert the unlocking plate 41 into the guide groove 223 on different top covers 2, and use the unlocking plate 41 to drive the guide groove 223 and the top cover 2 thereon to perform lifting movement together to realize the opening and closing of the top cover 2, effectively improving the versatility of the opening and closing driving device. Finally, the opening and closing driving device involved in the present embodiment is only equipped with a horizontal driving device 43 and a lifting driving device 5, which can control the movement of the unlocking plate 41 to realize automatic unlocking, automatic opening and closing of the top cover 2 and avoidance of the top opening of the box body 1, greatly reducing the setting of unnecessary parts, not only reducing costs, but also reducing the assembly difficulty and failure rate caused by the increase in parts.

[0083] like Figure 1 As shown, the horizontal drive device 43 includes a transverse frame 431 and a linear drive mechanism 432 that drives the transverse frame 431 to move back and forth along the first horizontal direction; wherein, the lifting drive device 5 is installed on the transverse frame 431, and the linear drive mechanism 432 is a movable drive component such as a cylinder or a hydraulic cylinder or a motor screw assembly that can realize linear reciprocating motion in a specific direction; in this embodiment, in order to ensure sliding stability, the transverse frame 431 is slidably set on the bottom frame 6.

[0084] In this embodiment, the transverse frame 431 includes a top support plate and two vertical support frames arranged below the top support plate along the second horizontal direction, and the top support plate and the two vertical support frames enclose a avoidance space for avoiding the box body 1; wherein, the two vertical support frames are slidably arranged on the bottom frame 6, and the lifting drive device 5 is installed on the top support plate of the transverse frame 431.

[0085] So, like Figure 1 、 Figure 11 As shown, when the top cover 2 is unlocked, the lifting drive device 5 will drive the unlocking plate 41 to move upward, so that the unlocking plate 41 contacts the limit plate 222 of the guide 22; when the unlocking plate 41 continues to move upward, the unlocking plate 41 will push the limit plate 222 to move upward together, thereby driving the top cover 2 in the unlocked state 2 to move upward together; when the top cover 2 in the unlocked state moves up to the open position, the unlocking plate 41 will cooperate with the top support plate of the transverse frame 431 to clamp the limit plate 222, thereby realizing the relative fixation of the unlocking plate 41, the transverse frame 431 and the top cover 2, and effectively reducing the risk of the top cover 2 slipping.

[0086] In order to facilitate the movement of the storage device, the bottom frame 6 is provided with a forklift opening or casters with brakes. Example 2

[0087] The only difference between this embodiment and the first embodiment is that the retracting member 31 a in the first embodiment is replaced by a pop-up member 31 b , and an unlocking trigger member 42 for unlocking the pop-up member 31 b is added to the unlocking plate 41 .

[0088] When the top cover 2 is opened, the unlocking plate 41 is inserted into the two guide grooves 223 above the top cover 2; then, the horizontal driving device 43 is started to drive the unlocking trigger 42 on the unlocking plate 41 to move in the direction close to the pop-up member 31b through the lifting driving device 5, until the unlocking trigger 42 pushes each pop-up member 31b to switch to the unlocking position, thereby switching the top cover 2 to the unlocked state. During this process, the unlocking plate 41 is still in the guide groove 223; then, the lifting driving device 5 is started to move the unlocking plate 41 and the unlocking trigger 42 upward together, and the unlocking plate 41 will drive the unlocked top cover 2 to the open position through the guide member 22; then, the horizontal driving device 43 is started to move the lifting driving device 5, the unlocking plate 41 and the top cover 2 supported above the unlocking plate 41 together in the direction away from the box body 1 until the unlocked top cover 2 is moved to the avoidance position to prevent the top cover 2 from occupying the space above the box body 1 and affecting the taking and placing of items.

[0089] When it is necessary to close the top cover 2, the horizontal driving device 43 is started, so that the lifting driving device 5, the unlocking plate 41, the unlocking trigger 42 and the top cover assembly supported above the unlocking plate 41 move together in the direction close to the box body 1, so as to move the top cover 2 in the unlocked state to just above the top opening of the box body 1; then, the lifting driving device 5 is started, so that the unlocking plate 41, the unlocking trigger 42 and the top cover 2 in the unlocked state move downward together until the top cover 2 is closed on the box body 1, and then the lifting driving device 5 drives the unlocking plate 41 to continue to move downward a certain distance, so that the unlocking plate 41 and the limit plate 222 are out of contact; then, the horizontal driving device 43 is started, so that the lifting driving device 5, the unlocking plate 41 and the unlocking trigger 42 move together in the direction away from the box body 1, so as to pull the unlocking plate 41 out of the guide groove 223. During this process, each pop-up member 31b will be restored to the locked position under the action of the corresponding pop-up elastic member 314b to complete the locking of the top cover 2.

[0090] When the unlocking trigger 42 contacts the ejection head 312b of the ejection member 31b to unlock, the structure of the unlocking trigger 42 is as follows: Figure 16 As shown (the arrow indicates the direction of movement of the unlocking plate 41 when unlocking each locking device 3). Specifically, the unlocking trigger 42 is L-shaped and includes a trigger rod and an adapter. The trigger rod can extend into the lock slot 111b to push the pop-up head 312b out of the corresponding lock slot 111b and reach the unlocked position.

[0091] refer to Figure 15, because when the pop-up head 312b of the pop-up member 31b exits the lock slot 111b, the trigger rod will be located in the lock slot 111b; in order to smoothly open the top cover 2, as Figure 7 As shown, the connecting plate 11b is provided with an escape opening 112b connected to the locking groove 111b; the escape opening 112b is located above the corresponding locking groove 111b and is connected to the top of the connecting plate 11b to form an open structure; when the pop-up head 312b of the pop-up member 31b is in the locked position, the pop-up head 312b cannot cross the locking groove 111b and enter the escape opening 112b above, ensuring the stability of the locking (such as Figure 8 When the eject head 312b of the eject member 31b is in the unlocked position, the escape opening 112 is used to escape the trigger rod in the vertical direction so that the trigger rod can smoothly enter and exit the lock slot 111b when the top cover 2 is opened or closed.

[0092] When the unlocking trigger 42 contacts the pop-up stopper 313b of the pop-up member 31b to unlock, Figure 16 As shown, the unlocking trigger 42 is a pull head that cooperates with the pop-up stop head 313b; when the unlocking plate 41 is inserted into the preset position of the two guide grooves 223, the pull head will pull the pop-up head 312b of the pop-up member 31b out of the corresponding lock groove 111b and reach the unlocking position; wherein, Figure 16 The direction of the arrow in FIG. 3 is the moving direction of the unlocking plate 41 when each ejection member 31 b is unlocked. Example 3

[0093] The only difference between this embodiment and embodiment 2 is the structural form of the multiple locking devices 3 on the top cover 2.

[0094] Specifically, if Figure 9 As shown, the multiple locking devices 3 on the top cover 1 include retracting members 31a and ejecting members 31b, and the retracting members 31a and ejecting members 31b are arranged in different rows. In this case, when the unlocking plate 41 is inserted into the preset position of the two guide grooves 223, the unlocking plate 41 can switch each retracting member 31a to the unlocked position, and the unlocking trigger on the unlocking plate 41 can switch each ejecting member 31b to the unlocked position, thereby achieving simultaneous unlocking of the retracting members 31a and ejecting members 31b.

[0095] It should be noted that the number of retracting members 31a can be one or more. When there are multiple retracting members 31a, the multiple retracting members 31a are spaced apart in a row along the second horizontal direction. Similarly, the number of ejecting members 31b can be one or more. When there are multiple ejecting members 31b, the multiple ejecting members 31b are spaced apart in a row along the second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. In this embodiment, there are two retracting members 31a and two ejecting members 31b. A space is formed between the two ejecting members 31b for the unlocking plate 41 to reciprocate along the first horizontal direction.

[0096] Compared with the single-row retractable parts 31a provided in the first embodiment and the single-row pop-up parts 31b provided in the second embodiment, the solution of locking the top cover 2 by combining the single-row retractable parts 31a with the single-row pop-up parts 31b adopted in this embodiment can effectively ensure the locking stability and locking reliability of the top cover 2 under different conditions. Example 4

[0097] The difference between this embodiment and embodiments 1 to 3 is only the structure and installation position of the horizontal driving device 43.

[0098] Specifically, the horizontal drive device 43 is installed on the lifting end of the lifting drive device 5, and the horizontal drive device 43 is used to drive the unlocking plate 41 to switch between the first position and the second position; when the unlocking plate 41 is in the first position, each locking device 3 is in the locking position; when the unlocking plate 41 is in the second position, each locking device 3 is in the unlocking position. Example 5

[0099] This embodiment, based on Embodiments 1-4, eliminates the guide member 22 of the top cover 2. Instead, the unlocking plate 41 is provided with a suction assembly for sucking the top cover 2. The suction assembly is controlled to achieve suction and release of the top cover 2. Since the suction assembly is conventional technology, its further description is omitted.

[0100] Of course, in other embodiments, the adsorption component can also be replaced by a clamping mechanism, and the top cover 2 can be clamped and released by the clamping mechanism.

[0101] At this time, the opening and closing method of the automatic opening and closing storage device includes the following two working conditions:

[0102] A. Top cover opening operation: The unlocking plate 41 is driven by the horizontal drive device 43 to move linearly in a first horizontal direction, causing each locking device 3 to store energy and switch to the unlocked state, thereby unlocking the top cover. The unlocked top cover 2 is then secured to the unlocking plate 41 by a suction assembly or a clamping assembly. The lifting drive device 5 retracts, causing the unlocking plate 41 and the unlocked top cover 2 to move upward together to a preset height, thereby opening the top cover 2.

[0103] B. Top cover closing condition: The lifting drive device 5 extends to move the unlocking plate 41 and the unlocked top cover 2 downward together until the top cover 2 is lowered to the top opening of the box body 1; then, the top cover 2 is released to release the relative fixation between the top cover 2 and the unlocking plate 41; then, the horizontal drive device 43 is started to move the unlocking plate 41 away from the locking device 3 on the top cover 2. During this process, the locking devices 3 on the top cover 2 automatically release energy and switch to the locked state, completing the closing and locking of the top cover 2.

[0104] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0105] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
