Referring to fig. 1 and fig. 2, the present invention provides a driving mechanism 30 for a cabinet for storing articles, such as a logistics cabinet, which is described herein as an example, but not limited thereto, the driving mechanism 30 is used for driving the cabinet door 20 of the logistics cabinet to move relative to the cabinet body 10.

In an embodiment of the present invention, please refer to fig. 1 to 4 in combination, the driving mechanism 30 includes a driving member 37, a driving gear set, a driven gear set and an elastic assembly 40, the driving gear set is connected to the driving member 37, the driving gear set includes a first gear 31, the driven gear set is connected to the cabinet door 20, the driven gear set includes a second gear 32 coaxially disposed with the first gear 31, one of two opposite end surfaces of the first gear 31 and the second gear 32 is provided with a limiting groove 321, the other end surface is provided with a limiting hole 311, the elastic assembly 40 is disposed in the limiting hole 311, the elastic assembly 40 has a locking state extending into the limiting groove 321 and an unlocking state separating from the limiting groove 321, in the locking state, the first gear 31 and the second gear 32 rotate synchronously, and in the unlocking state, the first gear 31 rotates relative to the second gear 32.

In particular, the drive 37 may be an electric or hydraulic motor. The driving gear set further includes a fifth gear 35, the fifth gear 35 is disposed on the main shaft of the driving member 37, and the fifth gear 35 is engaged with the first gear 31 to drive the fifth gear 35 to rotate by the driving member 37, so as to drive the first gear 31 to rotate. The first gear 31 and the second gear 32 are coaxially arranged, end faces of the first gear 31 and the second gear 32 are mutually attached or arranged in a small gap, and the first gear 31 and the second gear 32 can respectively and independently rotate. For example, the first gear 31 and the second gear 32 may be fixed to two rotation shafts, which are coaxial and can rotate independently, or the two rotation shafts may be fixed to the cabinet 10 or the cabinet door 20, and the first gear 31 and the second gear 32 can rotate on the rotation shafts. It is also possible to arrange the first gear 31 and the second gear 32 on the same rotation axis, with both the first gear 31 and the second gear 32 being able to rotate relative to the rotation axis, etc. In addition, the cabinet door 20 may be mounted on the second gear 32, or the driven gear set may further include a plurality of gears that are sequentially engaged, and the cabinet door 20 may be mounted on a gear that is away from the second gear 32, and so on.

The limiting hole 311 and the limiting groove 321 are correspondingly arranged, that is, when the first gear 31 and the second gear 32 rotate, the notch of the limiting groove 321 can be made to correspond to the hole of the limiting hole 311. The structure of the limiting groove 321 and the limiting hole 311 may be various, for example, the limiting groove 321 may be a hemispherical groove or an inverted cone groove, and the limiting hole 311 may be a through hole or a blind hole. In one embodiment, the limiting hole 311 is disposed on an end surface of the first gear 31 facing the second gear 32, and the limiting groove 321 is disposed on an end surface of the second gear 32 facing the first gear 31. In one embodiment, the limiting groove 321 is disposed on an end surface of the first gear 31 facing the second gear 32, and the limiting hole 311 is disposed on an end surface of the second gear 32 facing the first gear 31.

For example, in an embodiment, when the limiting hole 311 is a blind hole, the elastic element 40 may include a spring and an abutting member, one end of the spring abuts against the limiting hole 311, the other end of the spring is connected with the abutting member, and the abutting member is located at one end of the spring facing the limiting groove 321. Alternatively, the elastic member 40 may include an elastic rubber and an abutment. In one embodiment, when the limiting hole 311 is a through hole, the elastic component 40 may include a spring, an abutting member and a fastening member, the fastening member is fixed in the limiting hole 311, two ends of the spring respectively abut against the fastening member and the abutting member, and the abutting member is located at one end of the spring facing the limiting groove 321. In one embodiment, the elastic element 40 may be a bead screw.

When the first gear 31 and the second gear 32 rotate until the notches of the limiting groove 321 correspond to the holes of the limiting hole 311, the elastic component 40 can move towards the limiting groove 321 and extend into the limiting groove 321 to be in a locked state, and at this time, the first gear 31 and the second gear 32 can be locked to synchronously rotate. It should be noted that the elastic component 40 only partially extends into the limiting groove 321, and still partially locates in the limiting hole 311. When an external force is applied to prevent the second gear 32 from rotating, since the first gear 31 continues to rotate under the driving of the driving member 37, the portion of the elastic component 40 extending into the limiting groove 321 is subjected to a shearing action force generated by the mutual movement of the first gear 31 and the second gear 32, so that the elastic component 40 is forced to move towards the limiting hole 311 and disengage from the limiting groove 321, so as to be in an unlocking state, that is, when the elastic component 40 is in the unlocking state, the first gear 31 can continue to rotate, and the situation that the driving member 37 and the first gear 31 stop rotating when the second gear 32 stops rotating is avoided. After the external force is removed, the first gear 31 and the second gear 32 continue to rotate relatively until the limiting groove 321 corresponds to the limiting hole 311, and the elastic component 40 can extend into the limiting groove 321 to be in a locked state.

According to the technical scheme, the first gear 31 of the driving gear set and the second gear 32 of the driven gear set are coaxially arranged, the first gear 31 and the second gear 32 are respectively provided with the limiting groove 321 and the limiting hole 311, and the elastic component 40 is arranged in the limiting hole 311. When the first gear 31 and the second gear 32 rotate relatively until the limiting groove 321 corresponds to the limiting hole 311, the elastic component 40 can extend into the limiting groove 321 to be in a locked state, and at this time, the first gear 31 and the second gear 32 can be locked to rotate synchronously. I.e. when the cabinet door 20 is mounted on the driven gear set, the cabinet door 20 can be driven in motion. And exert external force to cabinet door 20 in the in-process of cabinet door 20 motion, when having hindered second gear 32 and rotated, because first gear 31 still continues to rotate under the drive of driving piece 37, the effort that produces elastic component 40 when first gear 31 and second gear 32 rotate relatively can force the cell wall of elastic component 40 relative spacing groove 321 to slide, and finally make elastic component 40 break away from spacing groove 321 and be in the unblock state, first gear 31 can continue to rotate under the drive of driving piece 37 this moment, avoided making first gear 31 and driving piece 37 also stall the card extremely because of second gear 32 stall, and then the condition that leads to driving piece 37, driving gear group and driven gear group to damage takes place. Can avoid actuating mechanism 30 when the automatic cabinet door 20 of opening, the manual cabinet door 20 that closes of user and lead to actuating mechanism 30 card to die the condition of damage and take place, greatly improved logistics cabinet's practicality and life-span. Even when driving piece 37 damaged, the user also can be through manual closing cabinet door 20, greatly improved the practicality of commodity circulation cabinet.

Referring to fig. 4 to 7, in an embodiment, the elastic component 40 includes a housing 41, a spring 42 and an abutting member 43, the housing 41 is engaged with the limiting hole 311, the spring 42 is respectively connected to the housing 41 and the abutting member 43, and in a locked state, the abutting member 43 extends into the limiting groove 321. Specifically, the housing 41 has an opening, the spring 42 and the abutting member 43 are disposed in the housing 41, the abutting member 43 is at least partially exposed outside the opening, and when the housing 41 is mounted in the limiting hole 311, the exposed portion of the abutting member 43 is used to extend into the limiting groove 321. In this way, the spring 42 and the contact piece 43 are provided in the housing 41 so that the elastic member 40 forms an integral member, which can reduce the number of mounting steps and facilitate mounting. Wherein, spacing hole 311 is the through-hole, and elastic component 40 can pack into spacing hole 311 from the one end of spacing hole 311 keeping away from spacing groove 321, can easy to assemble. Of course, in other embodiments, the length of the housing 41 may be set smaller than the length of the spring 42, such that the spring 42 is only partially located within the housing 41, and so on. Alternatively, the housing 41 may be a solid plug or stud, the spring 42 abutting a surface of the housing 41, or the like. In addition, the limiting hole 311 may be a blind hole, and the first gear 31 and the second gear 32 may be assembled after the elastic component 40 is installed in the limiting hole 311.

The mounting manner of the housing 41 is various, for example, in an embodiment, the limiting hole 311 is a screw hole, the housing 41 is provided with an external thread, and the housing 41 is screwed in the limiting hole 311, so that the structure is simple and the mounting is convenient. And the compression amount of the spring 42 can be adjusted by adjusting the depth of the shell 41 screwed into the limiting hole 311, so that the locking force of the elastic component 40 in a locking state can be adjusted, the proper locking force can be adjusted according to the weight of the cabinet door 20, the use environment, the structure of the driving mechanism 30 and other conditions, and the applicability is high.

In one embodiment, the abutment 43 is spherical. Specifically, the shape adaptation of spacing groove 321 and butt piece 43, the cell wall of spacing groove 321 is the hemisphere setting promptly, so make the area of contact of butt piece 43 and spacing groove 321 cell wall great, can improve the frictional force of butt piece 43 and spacing groove 321 cell wall to guarantee that elastic component 40 has great locking force, avoid also leading to the condition that elastic component 40 breaks away from spacing groove 321 to take place when cabinet door 20 self is heavier. In order to avoid that the stopper groove 321 becomes too deep and the contact piece 43 is difficult to come off, the groove depth of the stopper groove 321 is set to be smaller than the spherical radius of the contact piece 43. Of course, in other embodiments, the notch diameter of the limiting groove 321 may be set larger than the diameter of the abutting piece 43. Further, the groove depth of the stopper groove 321 may be equal to the spherical radius of the abutment 43.

For example, in an embodiment, the first gear 31 is provided with a plurality of limiting grooves 321, the plurality of limiting grooves 321 are arranged along the circumferential direction of the first gear 31 at intervals, the second gear 32 is provided with a plurality of limiting holes 311, the plurality of limiting holes 311 and the plurality of limiting grooves 321 correspond to each other one by one, and each limiting hole 311 is provided with an elastic component 40. That is, the number of the limiting holes 311 is the same as that of the limiting grooves 321, and the elastic elements 40 in each limiting hole 311 can correspondingly extend into the limiting grooves 321 at the same time. This can improve the locking effect of the first gear 31 and the second gear 32. Of course, in other embodiments, the elastic component 40 may be disposed only in a portion of the limiting hole 311. Or the number of the limiting holes 311 is less than that of the limiting grooves 321.

It can be understood that, since the rotation axis of the cabinet door 20 is disposed close to the outer side of the cabinet 10, if the first gear 31 and the second gear 32 are directly fixed at the edge of the cabinet 10 and the rotation axis of the cabinet door 20 is fixed on the first gear 31, the fixing area of the driving mechanism 30 on the cabinet 10 is small, and the stability is poor. And through setting up third gear 33 and fourth gear 34, can prolong the transmission distance of actuating mechanism 30, also can guarantee that actuating mechanism 30 is better fixed on cabinet body 10, also makes two adjacent cabinet doors 20 avoid the position setting. In addition, can also slow down through third gear 33 and fourth gear 34 to reduce the slew velocity of cabinet door 20, make cabinet door 20 rotate steadily, avoid cabinet door 20 slew velocity too fast and striking cabinet body 10 to lead to damaging.

The invention further provides a logistics cabinet, which includes a cabinet body 10, a cabinet door 20 and a driving mechanism 30, the specific structure of the driving mechanism 30 refers to the above embodiments, and since the logistics cabinet adopts all technical solutions of all the above embodiments, the logistics cabinet at least has all the beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein. The driving mechanism 30 is fixed to the cabinet 10 and is drivingly connected to the cabinet door 20, so that the cabinet door 20 rotates relative to the cabinet 10. That is, when the cabinet door 20 is in the closed state (see fig. 8), the driving mechanism 30 can drive the cabinet door 20 to automatically open to the open state (see fig. 9), so that the user can take the articles from the storage compartment of the cabinet 10. After the user takes the article, the cabinet door 20 can be driven to be automatically closed through the driving mechanism 30, so that the cabinet door 10 does not need to be manually opened or closed, and great convenience is brought to the user.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
