[0002] In the prior art, the vending machine includes multiple aisles and a movable pickup bucket. The aisles are provided with a push plate for pushing the goods to move and a transmission assembly connected to the push plate. The input end of the transmission assembly is a gear for the aisle. The pickup bucket is provided with a power assembly, and the output end of the power assembly is a transmission gear. When picking up goods, the pickup bucket moves to a position that matches the target aisle. First, the transmission assembly establishes a connection with the power assembly (i.e., the transmission gear meshes with the aisle gear), and then the power component operates. Through the transmission of the transmission assembly, the push plate moves the goods on the aisle to the pickup bucket, and the pickup bucket moves to the pickup port with the goods, thus completing the pickup process.

[0003] However, the inventors have found that the vending machines in the prior art have at least the following defects: the power assembly has many parts and components and is costly. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a power assembly, a pickup mechanism and a vending machine, which can effectively reduce the number of parts and components and save costs.

[0005] Based on the above purpose, the present invention provides a power assembly, comprising

[0006] A fixed bracket, fixedly installed on the pickup mechanism;

[0007] A driving motor is mounted on the fixing bracket;

[0008] A transmission shaft, fixedly connected to the output shaft of the drive motor;

[0009] A driving gear, fixedly mounted on the transmission shaft;

[0010] A swing bracket is rotatably mounted on the transmission shaft; a swing gear is rotatably mounted on the swing bracket, the swing gear is meshed with the driving gear, and the shaft of the swing gear protrudes outward to form a first abutment portion;

[0011] An elastic push member is installed on the swing bracket, and the elastic push member has a second abutment portion adapted to the first abutment portion.

[0012] As an optional embodiment, the elastic push member includes a first rod body, a connecting spring and a second rod body arranged in sequence along the axial direction, the first rod body is fixedly mounted on the swing bracket, the two ends of the connecting spring respectively abut the end of the first rod body and the second rod body, and the second abutting portion is located at an end of the second rod body away from the connecting spring.

[0013] As an optional embodiment, the second rod body has anti-slip blocks protruding symmetrically on both sides of the second abutment portion, and the distance between the two anti-slip blocks is greater than the distance between the top end of the first abutment portion and the central axis of the swing gear.

[0014] As an optional implementation, the first rod body and / or the second rod body is provided with a receiving groove, and at least a portion of the connecting spring is disposed in the receiving groove.

[0018] From the above description, it can be seen that the present invention provides a power component, a picking mechanism and an automatic vending machine. After the driving motor is started, the transmission shaft rotates, driving the active gear to rotate, and the swing gear meshes with the active gear. Since the first abutting portion of the swing gear and the second abutting portion of the elastic push member abut against each other, the abutting force between them makes the swing gear stationary relative to the swing bracket, and the active gear drives the swing bracket to drive the swing gear to swing until the swing gear meshes with the cargo lane gear. After the meshing, the cargo lane gear limits the further swinging of the swing gear. At this time, the thrust of the active gear on the swing gear gradually increases. When the thrust generated is greater than the elastic force of the elastic push member, the connection relationship between the first abutting portion and the second abutting portion is destroyed, and the swing gear starts to rotate, thereby driving the cargo lane gear to rotate, and further driving the push plate of the cargo lane to achieve the purpose of picking up goods. The structure is simple, the number of components is reduced, and the equipment cost can be effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] In order to achieve the above-mentioned purpose of the invention, an embodiment of the present invention provides a power assembly, which is applied to a pickup mechanism, such as Figure 1-6 Shown, including

[0030] A fixed bracket, fixedly installed on the pickup mechanism;

[0031] A driving motor 1 is mounted on the fixing bracket;

[0032] A transmission shaft 3, fixedly connected to the output shaft of the drive motor 1;

[0033] A driving gear 5 is fixedly mounted on the transmission shaft 3;

[0034] A swing bracket 4 is rotatably mounted on the transmission shaft 3;

[0035] A swing gear 6 is rotatably mounted on the swing bracket 4, the swing gear 6 is meshed with the driving gear 5, and the axial portion of the swing gear 6 protrudes outward to form a first abutment portion 61;

[0036] The elastic push member 7 is mounted on the swing bracket 4 , and the elastic push member 7 has a second abutting portion 73 a adapted to the first abutting portion 61 .

[0037] In this embodiment, after the driving motor 1 is started, the transmission shaft 3 rotates, driving the driving gear 5 to rotate, and the swing gear 6 is meshed with the driving gear 5. Since the first abutment portion 61 of the swing gear 6 and the second abutment portion 73a of the elastic push member 7 abut against each other, the abutment force between them makes the swing gear 6 stationary relative to the swing bracket 4, and the driving gear 5 drives the swing bracket 4 to drive the swing gear 6 to swing until the swing gear 6 is meshed with the cargo lane gear. After the meshing, the cargo lane gear limits the further swinging of the swing gear 6. At this time, the thrust of the driving gear 5 on the swing gear 6 gradually increases. When the thrust generated is greater than the elastic force of the elastic push member 7, the connection relationship between the first abutment portion 61 and the second abutment portion 73a is destroyed, and the swing gear 6 starts to rotate, thereby driving the cargo lane gear to rotate, and further driving the push plate of the cargo lane to achieve the purpose of picking up goods. The structure is simple, the number of components is reduced, and the equipment cost can be effectively reduced.

[0038] After the goods are picked up, the driving motor 1 rotates in the reverse direction, and under the action of the first abutting portion 61 and the second abutting portion 73a abutting against each other, the driving gear 5 drives the swing bracket 4 to return to the initial position.

[0039] As an optional implementation, if Figure 4 As shown, the elastic push member 7 includes a first rod body 71, a connecting spring 72 and a second rod body 73 arranged in sequence along the axial direction, the first rod body 71 is fixedly mounted on the swing bracket 4, the two ends of the connecting spring 72 respectively abut the ends of the first rod body 71 and the second rod body 73, and the second abutting portion 73a is located at an end of the second rod body 73 away from the connecting spring 72.

[0040] In this way, by providing the connection spring 72 between the first rod body 71 and the second rod body 73 , a continuous elastic force can be provided, so that the second contact portion 73 a contacts the first contact portion 61 .

[0041] Optional, such as Figure 6 As shown, the second rod body 73 is provided with anti-slip stoppers 73b symmetrically protruding outwardly on both sides of the second abutting portion 73a, and the distance between the two anti-slip stoppers 73b is greater than the distance between the top end of the first abutting portion 61 and the central axis of the swing gear 6. In this way, by providing the anti-slip stoppers 73b, the stability of the elastic push member 7 can be maintained.

[0042] Specifically, the first rod body 71 is provided with an avoidance hole, such as Figure 4 As shown, in order to avoid the transmission shaft 3.

[0043] Optionally, the first rod body 71 and / or the second rod body 73 are provided with a receiving groove, and at least a portion of the connecting spring 72 is disposed in the receiving groove. In this way, not only the working stability of the connecting spring 72 can be effectively improved, but also the occupied space can be effectively reduced, making the elastic push member 7 more compact.

[0044] As an optional implementation, Figure 1-3 As shown, the power assembly 100 further includes a reduction gear train 2, the input end and the output end of the reduction gear train 2 are respectively connected to the drive motor 1 and the transmission shaft 3. In this way, the speed of the transmission shaft 3 can be effectively controlled by setting the reduction gear train 2.

[0045] The present invention also provides a pickup mechanism adapted to the above-mentioned power assembly 100, such as Figure 7-8 As shown, the pickup mechanism has the power assembly 100 as described above.

[0046] Optionally, the picking mechanism includes a picking bucket 200 , the picking bucket 200 has an inlet 210 , and the swing gear 6 of the power assembly 100 is located below the inlet 210 .

[0047] Corresponding to the above-mentioned picking-up mechanism, the present invention further provides an automatic vending machine, including a vending machine body, wherein the automatic vending machine body is provided with the above-mentioned picking-up mechanism.
