Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration and cold storage, and particularly relates to a bottom support assembly of an intelligent vending cabinet with a gravity sensor and an intelligent vending cabinet. Background Technique

[0002] At present, unmanned vertical intelligent vending cabinets usually adopt a commodity recognition method that combines visual acquisition and a gravity sensing component. The gravity sensing component is usually arranged inside the cabinet. For example, a gravity sensing component is arranged in each cargo channel, or a set of double gravity sensing and pinching gravity sensing components is arranged on each layer of the shelf, or a set of double gravity sensing and pinching gravity sensing components is arranged on multiple layers of the shelf, etc.

[0003] In order to avoid the problem that "the gravity sensing data fluctuates due to the influence of the sudden change of the cold and heat inside the cabinet when the door is opened" existing in the installation of the gravity sensing component inside the cabinet, a solution has been developed at present to set a gravity sensing component at the connection between the four supporting wheels at the bottom of the vertical intelligent vending cabinet and the cabinet body to monitor the weight change inside the cabinet. The gravity sensing component of this solution is externally placed and is not affected by the temperature change inside the cabinet. For example, the bottom support assembly for an intelligent vending cabinet disclosed in Patent CN220962503U sets the gravity sensor in the accommodation cavity of the bottom support frame. By connecting the first end of the gravity sensor to the bottom support frame and the second end to the support foot, the total weight change of the intelligent vending cabinet body and the commodities inside it is completely transmitted to the gravity sensor through the bottom support frame, so as to use the gravity sensor to monitor the weight change of the commodities inside the cabinet and realize commodity recognition. However, in this solution, since the four support feet are respectively connected to the four gravity sensors, it is difficult to completely level the cabinet body during use, which affects the stability of the gravity sensor to obtain weight data and the accuracy of commodity recognition.

[0004] Therefore, how to provide a bottom support assembly of an intelligent vending cabinet with a gravity sensor that is convenient for leveling is a technical problem that needs to be solved urgently at present. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] As attached Figures 1 - 4As shown in the figure, in a schematic embodiment of the bottom support assembly of the intelligent vending cabinet with a gravity sensor according to the present utility model, the bottom support assembly of the intelligent vending cabinet with a gravity sensor includes a support frame assembly 1, four support wheels 2, and four gravity sensors 5; the support frame assembly 1 includes a bottom support frame 12 and a top support frame 11 buckled on the bottom support frame 12. The top support frame 11 is used to connect to the bottom of the cabinet body of the intelligent vending cabinet to support the cabinet body. The bottom of the top support frame 11 is provided with an open mouth to buckle on the bottom support frame 12, and the top of the bottom support frame 12 is provided with an open mouth, so as to form a receiving cavity a between the bottom support frame 12 and the top support frame 11; the four support wheels 2 are respectively connected to the four corners of the bottom of the bottom support frame 12, so that the bottom support frame 12 is supported on the ground; the four gravity sensors 5 are respectively arranged in the receiving cavity a and are symmetrically arranged. The four gravity sensors 5 are only connected to the four corners of the bottom support frame 12 through the bottom of their first ends, and the other parts are not in contact with the bottom support frame 12. The four gravity sensors 5 are only connected to the four corners of the top support frame 11 through the top of their second ends, and the other parts are not in contact with the top support frame 11, so that the gravity sensors 5 are in a suspended state in the receiving cavity a, and the top support frame 11 and the bottom support frame 12 are not in contact with each other and are only connected through the four gravity sensors 5. It should be noted that the size of the top support frame 11 is adapted to the size of the bottom of the cabinet body to serve as the bottom surface of the cabinet body.

[0038] The working principle of the above-mentioned bottom support assembly of the intelligent vending cabinet with a gravity sensor is as follows: In the support frame assembly 1, the bottom support frame 12 is supported on the ground through the support wheels 2, and the top support frame 11 is used to support the cabinet body of the intelligent vending cabinet. By arranging the gravity sensors 5 at the four corners of the receiving cavity a between the bottom support frame 12 and the top support frame 11, the top support frame 11 is suspended on the bottom support frame 12 and does not directly contact each other. The top support frame 11 and the bottom support frame 12 are only connected through the gravity sensors 5, so that the total weight change of the cabinet body and the commodities inside it is completely transmitted to the gravity sensors 5 through the top support frame 11, so as to realize the identification of commodities by using the gravity sensors 5. Since the four gravity sensors 5 are all connected to the bottom support frame 12, during leveling, only the bottom support frame 12 needs to be leveled, and the top support frame 11 can be leveled under the action of the four symmetrically arranged gravity sensors 5, so as to level the cabinet body.

[0039] In the bottom support assembly of the above-mentioned intelligent vending cabinet with gravity sensors, four gravity sensors 5 provided at the four corners are respectively connected to the four corners of the bottom support frame 12 through the bottoms of their first ends and to the four corners of the top support frame 11 through the tops of their second ends, so that the top support frame 11 for supporting the cabinet body is suspended above the bottom support frame 12 supported on the ground. During leveling, only by leveling the bottom support frame 12 can the top support frame 11 be leveled under the action of the four gravity sensors 5, thereby leveling the cabinet body, facilitating the leveling operation, and being beneficial to ensuring the accuracy of commodity recognition. Moreover, in the bottom support assembly of the above-mentioned intelligent vending cabinet with gravity sensors, the four gravity sensors 5 are completely concealed and installed in the accommodation cavity a formed between the bottom support frame 12 and the top support frame 11, which is beneficial to avoiding damage to the gravity sensors 5 and extending the service life.

[0040] As Figure 3 and Figure 4 shown, the bottom of the first end of the gravity sensor 5 is connected to the bottom support frame 12 through the first gasket 6, and the top of the second end of the gravity sensor 5 is connected to the top support frame 11 through the second gasket 7 to prevent the gravity sensor 5 from contacting the bottom support frame 12 and the top support frame 11 and ensure the suspended state of the gravity sensor 5 in the accommodation cavity a. It should be noted that the first end of the gravity sensor 5, the first gasket 6, and the bottom support frame 12 are tightly connected by screws from top to bottom, and the top support frame 11, the second gasket 7, and the second end of the gravity sensor 5 are tightly connected by screws from top to bottom for easy installation.

[0041] As Figure 3 shown, the outer frame of the top support frame 11 is sleeved outside the outer frame of the bottom support frame 12 so that the top support frame 11 is buckled on the bottom support frame 12, which is beneficial to preventing sundries from falling into the accommodation cavity a formed between the top support frame 11 and the bottom support frame 12 and interfering with the accuracy of the gravity sensor 5 in recognizing commodities.

[0042] As Figure 4 and Figure 5 shown, a notch b for avoiding the second gasket 7 is provided on the outer frame of the bottom support frame 12 to prevent the side frame of the bottom support frame 12 from contacting the second gasket 7 and interfering with the detection accuracy of the gravity sensor 5.

[0043] As Figure 1 and Figure 6 shown, a support foot 3 for fixedly supporting the bottom support frame 12 on the ground to restrict the movement of the bottom support frame 12 is provided at the bottom of the front frame of the bottom support frame 12. By providing the support foot 3, the intelligent vending cabinet can be fixed to prevent the intelligent vending cabinet from moving and affecting the accuracy of the gravity sensor 5 in recognizing commodities. Specifically, as Figure 6As shown in the figure, the supporting foot 3 includes an adjusting nut 31 rotatably connected to the front frame of the bottom support frame 12, a screw rod 32 threadedly connected to the adjusting nut 31, and a supporting foot 33 fixedly connected to the bottom of the screw rod 32. After the bottom support assembly of the intelligent vending machine carries the intelligent vending machine to the designated position, by rotating the adjusting nut 31, the supporting foot 33 can be lowered until the supporting foot 33 tightly presses on the ground, and then fixation can be achieved. When the intelligent vending machine needs to be moved, by rotating the adjusting nut 31 in the reverse direction, the supporting foot 33 can be raised to leave the ground. At this time, by pushing the intelligent vending machine and through the rotation of the supporting wheels 2, the intelligent vending machine can be moved.

[0044] As Figure 1 , Figure 2 and Figure 4 As shown in the figure, at the rear part of the rear frame of the bottom support frame 12, there is a wall stop 4 for keeping a distance between the rear side of the bottom support frame 12 and the rear wall. The wall stop 4 protrudes beyond the top support frame 11. By providing the wall stop 4, a distance is kept between the rear side of the bottom support frame 12 and the rear wall, so that the top support frame 11 buckled on the bottom support frame 12 is kept away from the rear wall in a suspended state, avoiding the influence of the top support frame 11 and the cabinet body supported thereon contacting the rear wall on the accuracy of the gravity sensor 5 for identifying goods.

[0045] Based on the above bottom support assembly of the intelligent vending machine with a gravity sensor, the present invention further provides an intelligent vending machine, including a cabinet body, and the bottom of the cabinet body is provided with the above bottom support assembly of the intelligent vending machine with a gravity sensor. In this intelligent vending machine, by using the above bottom support assembly of the intelligent vending machine with a gravity sensor as the bottom support of the cabinet body, it can support the cabinet body while realizing the identification of goods in the cabinet.

[0046] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and the key points of each embodiment are the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still, the specific implementation manners of the present invention can be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
