Description

Technical Field

[0001] The present invention belongs to the technical field of logistics and transportation, and in particular relates to a delivery box and a delivery robot. Background Art

[0002] With the development of technology, delivery robots such as unmanned delivery vehicles have emerged. The delivery robots can automatically move to the designated location of the user to receive the goods, so that the user to receive the goods can shop without going to a fixed shopping place, thereby improving the user's shopping experience; and the delivery robots can automatically move to the loading position, and staff or robotic arms can place the goods on the delivery robots.

[0003] Since the shapes of goods delivered by the delivery robot are various, the goods need to be installed on the delivery robot using a pallet or storage box. After the delivery robot drives the goods to the user, the user only needs to take the goods without moving the pallet or storage box. When the delivery robot is loading the goods, it needs to take out the old pallet or storage box, and then install the new pallet or storage box containing the goods on the delivery robot. Therefore, a locking structure is required to lock the storage box or pallet in the storage bin of the delivery robot. In the prior art, each pallet or storage box needs to be provided with a locking member to lock it in the storage bin of the delivery robot, and each locking member must be equipped with a driving member to drive it to unlock or unlock. However, this design of multiple locking members and multiple driving members increases the manufacturing cost of the delivery robot and increases the weight of the delivery robot. Summary of the Invention

[0008] When the driving member drives the cam to rotate through the transmission rod until the triggering portion of the locking member is inserted into the groove, the locking tongue of the locking member is inserted into the lock hole, so that the storage member is locked in the storage space;

[0009] When the driving member drives the cam to rotate through the transmission rod until the protrusion abuts against the triggering portion of the locking member, the locking tongue of the locking member retracts from the locking hole to release the lock of the storage member.

[0010] Optionally, the two opposite groove edges of the groove are respectively an unlocking groove edge and a locking groove edge; along the axial direction of the transmission rod, the opening curvature of the plurality of grooves increases successively; wherein the opening curvature is the curvature value between the unlocking groove edge and the locking groove edge;

[0011] In a plane perpendicular to the axis of the transmission rod, all the locking groove edges coincide with each other.

At this time, the storage members are locked in the storage space by the locking members, and the locking tongues of each locking member will be inserted into the lock holes of the corresponding storage members.

[0022] When the driving member drives all the cams to rotate through the transmission rod until the triggering portion of one of the locking members abuts against the corresponding convex portion of the cam, the locking tongue of the locking member will retract from the lock hole of the storage member, and the locking member in the retracted lock tongue state will release the locking state of the corresponding storage member, so that the user can take out the unlocked storage member from the storage space. The transmission rod is sleeved with multiple cams. Each cam can trigger a locking member, and each locking member can lock a storage member in the storage space. In the present invention, the unlocking function of multiple locking members can be realized by driving the rotation of multiple cams by a driving member and a transmission rod, which reduces the manufacturing cost of the delivery box and facilitates the opening and unlocking operations of multiple locking members.

[0033] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It should be understood that the terms "upper", "lower", "left", "right", "front", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0035] like Figures 1 to 3As shown, a delivery box 10 provided by an embodiment of the present invention includes a locking assembly 1, a box body 2 provided with a storage space 21, and a storage piece 3 for storing goods; it can be understood that the storage piece 3 includes but is not limited to a tray and a storage box, etc., and the storage space 21 can be composed of a plurality of storage bins distributed at intervals, or it can be an integral space; when the storage space 21 is a plurality of storage bins distributed at intervals, each of the output bins can store one storage piece 3; when the storage space 21 is an integral space, a plurality of the storage pieces 3 can be installed in the storage space 21 in a stacked form, and the heights of different storage pieces 3 can be designed according to actual needs, and users can install different storage pieces 3 in the storage space 21 in different combinations.

[0036] The locking assembly 1 includes a driving member 11, a transmission rod 12, a plurality of locking members 13 and a plurality of cams 14 sleeved on the transmission rod 12, the transmission rod 12 is rotatably mounted on the box body 2, and the driving member 11 is connected to the transmission rod 12; each of the cams 14 is provided with a convex portion 141 for triggering the locking member 13 (the triggering portion 131), and the convex portion 141 is provided with a groove 142; it can be understood that the driving member 11 includes but is not limited to a rotating motor 301, etc., and the number of the locking members 13 and the cams 14 can be designed according to actual needs. For example, the locking members 13 and the cams 14 are both provided with 3, 4, 5, etc., and the number of the locking members 13 is equal to the number of the cams 14.

[0037] The locking member 13 is installed on the box body 2, the storage member 3 is provided with a lock hole 31, and the storage member 3 is installed in the storage space 21; it can be understood that the locking member 13 is provided with a lock tongue 132 inserted into the lock hole 31, and the locking member 13 is also provided with a trigger part 131 opposite to the protrusion 141 of the cam 14.

[0038] like Figure 3 As shown, when the driving member 11 drives the cam 14 to rotate through the transmission rod 12 until the triggering portion 131 of the locking member 13 is inserted into the groove 142, the locking tongue 132 of the locking member 13 is inserted into the locking hole 31, so that the storage member 3 is locked in the storage space 21; it can be understood that when the triggering portion 131 of the locking member 13 is located in the groove 142 of the cam 14, the locking member 13 is in a locked state (that is, a free state), and the locking tongue 132 of the locking member 13 is inserted into the locking hole 31 of the storage member 3, so that the storage member 3 is locked in the storage space 21. At this time, the user cannot take out the storage member 3 from the storage space 21.

[0039] like Figure 4 As shown, when the driving member 11 drives the cam 14 to rotate through the transmission rod 12 until the protrusion 141 abuts against the triggering portion 131 of the locking member 13, the locking tongue 132 of the locking member 13 retracts from the locking hole 31 to release the lock of the storage member 3. It can be understood that when the protrusion 141 of the cam 14 abuts against the triggering portion 131 of the locking member 13, the locking tongue 132 of the locking member 13 will retract into the housing of the locking member 13 (the locking member 13 is in the unlocked state), that is, the locking member 13 will retract from the locking hole 31 of the storage member 3, thereby releasing the locking state of the storage member 3; at this time, the user can take out the storage member 3 from the storage space 21.

[0040] In the present invention, when the driving member 11 drives all the cams 14 to rotate through the transmission rod 12 until the triggering parts 131 of all the locking members 13 are inserted into the corresponding grooves 142 of the cams 14, the locking tongues 132 of the locking members 13 are in a locked state (the locking tongues 132 can be retracted and popped out). At this time, the storage member 3 is locked in the storage space 21 by the locking member 13, and the locking tongue 132 of each locking member 13 will be inserted into the lock hole 31 of the corresponding storage member 3.

[0041] When the driving member 11 drives all the cams 14 to rotate through the transmission rod 12 until the trigger portion 131 of one of the locking members 13 abuts against the corresponding protrusion 141 of the cam 14, the locking tongue 132 of the locking member 13 will retract from the lock hole 31 of the storage member 3. The locking member 13 with the locking tongue 132 retracted will release the locking state of the corresponding storage member 3, so that the user can take out the unlocked storage member 3 from the storage space 21. The transmission rod 12 is equipped with multiple cams 14. Each cam 14 can trigger a locking member 13, and each locking member 13 can lock a storage member 3 in the storage space 21. In the present invention, the unlocking function of multiple locking members 13 can be achieved by driving the rotation of multiple cams 14 by a single driving member 11 and a transmission rod 12, thereby reducing the manufacturing cost of the delivery box 10 and facilitating the opening and unlocking operations of the multiple locking members 13.

[0042] In one embodiment, if Figure 5As shown, the two opposite groove edges of the groove 142 are respectively the unlocking groove edge 143 and the locking groove edge 144; along the axial direction of the transmission rod 12, the opening curvature a of the plurality of grooves 142 increases successively; wherein, the opening curvature a is the curvature value between the unlocking groove edge 143 and the locking groove edge 144; it can be understood that the locking groove edge 144 and the unlocking groove edge 143 are both transition portions between the convex portion 141 and the groove 142; specifically, from bottom to top, the opening curvatures of the plurality of grooves 142 increase successively, that is, the opening curvature of the cam 14 located at the bottom is the largest, and the opening curvature of the cam 14 located at the top is the smallest. It should be noted that during the rotation of the cam 14, the triggering portion 131 of the locking member 13 slides over the locking groove edge 144 and abuts against the protrusion 141, and the triggering portion 131 of the locking member 13 slides over the unlocking groove edge 143 and inserts into the groove 142; that is, during the rotation of the cam 14, the locking groove edge 144 is the triggering point for the locking member 13 to change from the unlocked state to the locked state, and the unlocking groove edge 143 is the triggering point for the locking member 13 to change from the locked state to the unlocked state.

[0043] All the locking groove edges 144 overlap in a plane perpendicular to the axis of the transmission rod 12. It can be understood that when the transmission rod 12 drives all the cams 14 to rotate, all the locking groove edges 144 trigger the locking members 13 at the same time, that is, all the locking members 13 change from the unlocked state to the locked state at the same time. It should be noted that, in the absence of external force, the trigger portion 131 and the lock tongue 132 of the locking member 13 are both in an extended state, and the trigger portion 131 of the locking member 13 retracts into the housing of the locking member 13 under the action of a thrust, and when the trigger portion 131 of the locking member 13 is contacted with a thrust, the trigger portion 131 of the locking member 13 will be reset to the extended state; the lock tongue 132 of the locking member 13 retracts into the housing of the locking member 13 under the action of a thrust, and when the lock tongue 132 of the locking member 13 is contacted with a thrust, the lock tongue 132 of the locking member 13 will be reset to the extended state.

[0044] Specifically, in the process of the driving member 11 driving all the cams 14 to rotate through the transmission rod 12, the protrusion 141 of the top cam 14 first contacts the triggering portion 131 of the top locking member 13, and the locking tongue 132 of the top locking member 13 retracts from the lock hole 31 of the top storage member 3, so that the user can take out the top storage member 3 from the storage space 21; the transmission rod 12 continues to drive all the cams 14 to rotate, and the lower cams 14 will unlock the corresponding locking members 13 in turn until all the cams 14 drive all the locking members 13 to be in the unlocked state; and when the lower locking member 13 is in the unlocked state, the locking member 13 above it is also in the unlocked state. The transmission rod 12 continues to drive all the cams 14 to rotate. When the locking groove edges 144 of all the cams 14 slide over the triggering portion 131 of the locking member 13 at the same time, the triggering portion 131 of all the locking members 13 is inserted into the corresponding groove 142 of the cam 14 at the same time, and then all the locking members 13 are in a locked state at the same time.

[0045] In this embodiment, as the drive member 11 drives the transmission rod 12 to rotate, the locking members 13 are sequentially unlocked by the corresponding cams 14 from top to bottom, allowing the user to sequentially remove the storage items 3 from the storage space 21 from top to bottom. All of the locking members 13 are locked by all of the cams 14 at the same time, thereby facilitating the control of the opening and unlocking functions of the delivery box 10. In particular, when the storage space 21 is a single unit, multiple storage items 3 are stacked in the storage space 21, allowing the user to sequentially remove the storage items 3 from the storage space 21 from top to bottom. Furthermore, the storage space 21 can accommodate storage items 3 of varying heights according to actual needs. When the storage space 21 is empty or one of the storage items 3 is tall, the locked locking tongue 132 of the locking member 13 will be inserted into the air hole or abut against the outer wall of the taller storage item 3.

[0046] In one embodiment, if Figure 1 、 Figure 2 as well as Figure 6As shown, the delivery box 10 also includes a sensing component 4, which includes a first position sensor 41 installed on the box body 2 and a first disc 42 sleeved on the transmission rod 12, and the first disc 42 is provided with a first reset notch 421 and a plurality of unlocking notches 422 distributed in an annular manner. The first reset notch 421 is used to indicate that all the locking members 13 are in a locked state, and each of the unlocking notches 422 is used to indicate that one of the locking members 13 is in an unlocked state; it can be understood that each of the unlocking notches 422 corresponds to a locking groove edge 144 of the cam 14, and the first reset notch 421 is used to indicate that all the locking members 13 are in a locked state, that is, the triggering parts 131 corresponding to all the locking members 13 are inserted into the groove 142 of the corresponding cam 14.

[0047] The first position sensor 41 is provided with a first sensing groove 411 for sensing the first reset notch 421 and the unlocking notch 422. It is understood that a laser emitter and a laser receiver are respectively provided on the opposing inner walls of the first sensing groove 411. When the solid portion of the first disc 42 rotates into the first sensing groove 411, the laser light emitted by the laser emitter is blocked by the first disc 42, preventing the laser light from being received by the laser receiver. When the first reset notch 421 or the unlocking notch 422 of the first disc 42 rotates into the first sensing groove 411, the laser light emitted by the laser emitter passes through the notch and is received by the laser receiver. Based on this principle, the first position sensor 41 senses the position of the first disc 42 after rotation. In this embodiment, the cam 14, the locking member 13, and the unlocking notch 422 all correspond to each other.

[0048] Specifically, when the transmission rod 12 drives all cams 14 and the first disc 42 to rotate, when the first reset notch 421 rotates into the first sensing groove 411 of the first position sensor 41, it indicates that all the locking members 13 are in a locked state (that is, the trigger portion 131 of the locking member 13 is inserted into the groove 142 of the corresponding cam 14); when one of the unlocking notches 422 of the first disc 42 rotates into the first sensing groove 411 of the first position sensor 41, it indicates that the corresponding locking member 13 is in an unlocked state. It should be noted that along the direction of rotation of the first disc 42, the first unlocking notch 422 adjacent to the first reset notch 421 corresponds to the topmost locking member 13, and the first disc 42 drives the unlocking notches 422 to enter the first sensing groove 411 of the first position sensor 41 in sequence, thereby detecting the unlocked state of all the locking members 13. In this embodiment, the design of one first position sensor 41 and one first disc 42 can sense the open and unlock states of all the locking members 13 , thereby further reducing the manufacturing cost of the delivery box 10 .

[0049] In one embodiment, if Figure 1 、 Figure 2 as well as Figure 6 As shown, the sensing assembly 4 further includes a second disc 43, a sleeve 44, and a second position sensor 45 mounted on the housing 2. The first disc 42 and the second disc 43 are mounted at opposite ends of the sleeve 44. The second disc 43 is provided with a second reset notch 431 for indicating that all locking members 13 are in the locked state. The sleeve 44 and the second disc 43 are both sleeved onto the transmission rod 12, and the second position sensor 45 is provided with a second sensing groove for sensing the second reset notch 431. It is understood that the first disc 42, the sleeve 44, and the second disc 43 are integrally formed components; in a plane perpendicular to the axis of the transmission rod 12, the first reset notch 421 and the second reset notch 431 overlap. Specifically, when the notch on the first disk 42 rotates into the first sensing groove 411 of the first position sensor 41, the first position sensor 41 corresponds to a signal of "1", and when the solid part of the first disk 42 rotates into the first sensing groove 411, the first position sensor 41 corresponds to a signal of "0"; similarly, when the notch on the second disk 43 rotates into the first sensing groove 411 of the second position sensor 45, the second position sensor 45 corresponds to a signal of "1", and when the solid part of the second disk 43 rotates into the second sensing groove, the second position sensor 45 corresponds to a signal of "0".

[0050] In this embodiment, only when the first reset notch 421 of the first disc 42 rotates to the first sensing groove 411 of the first position sensor and the second reset notch 431 of the second disc 43 rotates to the second sensing groove of the second position sensor 45 can it be detected that all the locking members 13 are in the locked (i.e., reset) state. Because the opening arcs of the grooves 142 of all cams 14 increase sequentially along the axis of the transmission rod 12, the unlocked state of all the locking members 13 can only be sequentially detected during the process of the transmission rod 12 driving the cams 14, the first disc 42, and the second disc 43 to rotate. In this embodiment, the unlocked state of all the locking members 13 can be detected based on the "0" and "1" signals of the first position sensor 41 and the second position sensor 45, thereby reducing the performance requirements of the first position sensor 41 and the second position sensor 45.

[0051] In one embodiment, if Figure 7 As shown, the storage member 3 is a storage box, and the outer wall of the storage box is provided with the lock hole 31. It can be understood that the front of the storage box is an open structure, and the outer wall of the storage box is provided with the lock hole 31. Multiple storage boxes can be stacked and stored in the storage space 21. In this embodiment, the storage box can protect objects from all sides, preventing the stored objects from rubbing against each other.

[0052] like Figure 7 As shown, another embodiment of the present invention provides a delivery robot comprising a robot body 20 and the aforementioned delivery box 10. The robot body 20 is provided with an installation space, and the box 2 is installed in the installation space. It is understood that the delivery robot can be an unmanned robot that can automatically move the delivery box 10 and the objects inside.

[0053] In one embodiment, if Figure 7 As shown, the delivery robot further includes a drive assembly 30 mounted on the robot body 20, and the drive assembly 30 is used to drive the box 2 to move out of or into the installation space. It is understood that the drive assembly 30 includes but is not limited to a linear motor 301, a pneumatic cylinder, a hydraulic cylinder, and a screw-nut mechanism.

[0054] Specifically, when the delivery robot moves to the loading station, the drive assembly 30 drives the box body 2 out of the installation space until it docks with the docking bin. The drive member 11 drives all cams 14 to rotate via the transmission rod 12. All cams 14 in turn drive the locking member 13 to an unlocked state, so that an external manipulator can sequentially remove old storage items 3 from the storage space 21 from top to bottom. After that, the external manipulator can install new storage items 3 in the storage space 21 from bottom to top. Then, the drive assembly 30 drives the box body 2 back to the installation space, thereby completing the loading step of the delivery robot. In this embodiment, the design of the drive assembly 30 improves the automation level of the delivery robot.

[0055] In one embodiment, if Figure 7 As shown, the drive assembly 30 includes a motor 301, a gear (not shown), and a rack 302 mounted on the outer wall of the housing 2. The motor 301 is mounted on the robot body 20, and the gear is mounted on the output shaft of the motor 301, meshing with the rack 302. Specifically, the motor 301 drives the gear to rotate, which moves via the rack 302, thereby driving the housing 2 into or out of the installation space. In this embodiment, the drive assembly 30 has a simple structure and low manufacturing cost.

[0056] In one embodiment, if Figure 7 As shown, the delivery robot further includes a guide rail (not shown) mounted on the inner wall of the installation space, and a slider 40 mounted on the outer wall of the box 2; the slider 40 is slidably connected to the guide rail; and the drive assembly 30 is used to drive the box 2 to slide on the guide rail via the slider 40. It is understood that the slider 40 can be mounted on the outer wall of the box 2. During the process of the drive assembly 30 driving the box 2 to move, the box 2 slides on the guide rail via the slider 40, thereby ensuring the stability of the movement of the box 2.

[0057] In one embodiment, if Figure 1As shown, the delivery robot further includes a trigger 50 mounted on the box 2, and the trigger 50 is electrically connected to the drive assembly 30. It is understandable that the trigger 50 is electrically connected to the drive assembly 30 via a controller; the trigger 50 is mounted at the front end of the box 2. When the drive assembly 30 drives the box 2 out of the installation space, when the trigger 50 abuts against the docking station, the trigger 50 will send a stop signal to the controller, which will control the drive assembly 30 to stop driving the box 2, thereby preventing the box 2 from falling from the installation space, thereby further improving the automation level of the delivery robot.

[0058] The above are merely embodiments of the delivery box and delivery robot of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
