Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, specifically to a vending machine with a door positioning device. Background Technology

[0002] A vending machine is a smart device that automatically sells goods, allowing users to conveniently and quickly purchase beverages, snacks, daily necessities, and other items. For ease of restocking, maintenance, and cleaning, vending machines are typically designed with a front-opening door. The door is hinged to the machine body, allowing staff to open it for operation. Currently, most vending machine doors use hinges with a spring-loaded mechanism. This design ensures the door automatically locks after closing, preventing accidental opening due to external impact. However, this design also presents some problems in practical applications.

[0003] Existing vending machines using hinges with spring-loaded mechanisms often experience difficulties in retrieving and placing items due to excessive spring force. Common hinges with positioning functions tend to wear down and fail after frequent use, causing the door to fail to stay securely in the desired position when opened. Some vending machine hinges lack any spring force at all, failing to close automatically after opening. If staff forget to close the door, this can easily lead to property damage and equipment failure. Over-reliance on hinges for door positioning, without a proper positioning structure design, often negatively impacts the user experience and safety of vending machines, while also increasing maintenance difficulty and costs.

[0004] Therefore, the market urgently needs an automated vending machine with a door positioning device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic vending machine with a door positioning device, so as to solve the problem mentioned in the background art that the lack of a good positioning structure design affects the actual user experience and safety of the automatic vending machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic vending machine with a door positioning device, comprising a body and a door frame, wherein the door frame is installed at the top front end of the body, and a door panel is hinged to the body through the door frame, and a stainless steel spring hinge is installed between the door frame and the door panel; a top groove is provided at the top inside the body, and a positioning structure is provided in the top groove; the positioning structure includes two sets of springs fixed to the rear of the inner wall of the top groove, and a movable plate is fixedly mounted at the front end of the springs; a first damping ball, a second damping ball, and a third damping ball are respectively provided at the front end of the movable plate from right to left; a set of movable seats is movably connected inside the door frame, and a telescopic rod is hinged between the front end of the movable seat and the door panel; a touch rod with an infrared sensor is fixedly connected to the rear end of the movable seat, and the touch rod with the infrared sensor abuts against the movable plate.

[0007] Preferably, the first damping ball, the second damping ball, and the third damping ball are all hemispherical and their surfaces are coated with butyl rubber.

[0008] Preferably, a track is provided in the top groove along its length, and a roller is installed on the lower half of the rear end of the movable seat, the roller being embedded in the track and rolling.

[0009] Preferably, movable grooves are provided on both sides of the inner wall of the top groove along its width direction, and the movable plate is respectively embedded in the movable grooves and moves.

[0010] Preferably, the spring includes a mounting piece whose front end is fixedly bonded to it, and the mounting piece is fixedly connected to the movable plate by a fixing bolt.

[0011] Preferably, the front end of the movable plate is provided with a first contact piece, a second contact piece, a third contact piece and a fourth contact piece from right to left, and the first contact piece, the second contact piece, the third contact piece and the fourth contact piece are distributed at intervals with the first damping ball, the second damping ball and the third damping ball.

[0012] Preferably, the telescopic rod is a metal rod that is nested and slides together.

[0013] Preferably, a removable cover is provided at the rear of the machine body, and the position of the removable cover corresponds to the top groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the vending machine with door positioning device not only realizes multi-angle positioning and opening to meet the opening needs in different scenarios and realizes infrared detection of door angle, but also realizes a hidden structure that is not easy to be damaged and easy to maintain;

[0015] (1) By incorporating a movable seat, an infrared sensor-equipped contact rod, a movable plate, a first damping ball, a second damping ball, a third damping ball, and a spring, this vending machine has a positioning structure in the top slot for locating the door angle. A movable seat is added to the telescopic rod. When the telescopic rod extends as the door opens, causing the movable seat to move from right to left, the infrared sensor-equipped contact rod at the rear end of the movable seat also moves from right to left at the movable plate. The three sets of damping balls correspond to 90°, 120°, and 150° respectively. When the infrared sensor-equipped contact rod touches the damping ball, force is required. As the door panel continues to open, the infrared sensor-equipped touch rod crosses the first damping ball. Due to the presence of the spring, the movable plate will move backward, ensuring that the door panel can open to the corresponding degree after a certain force is applied. If no further force is applied, the infrared sensor-equipped touch rod will remain between the two sets of damping balls, overcoming the rebound force of the stainless steel spring hinge. The door can then be positioned near the corresponding degree, thus achieving multi-angle positioning and opening function. This function avoids the door panel opening angle being too large and also avoids the problem of automatic closing due to insufficient opening angle, meeting the opening needs in different scenarios.

[0016] (2) By setting up a first contact piece, a second contact piece, a third contact piece, a fourth contact piece, a first damping ball, a second damping ball, and a third damping ball, the first contact piece, the second contact piece, the third contact piece, and the fourth contact piece are distributed at intervals with the first damping ball, the infrared sensor rod crosses the first damping ball and comes to the second contact piece, the infrared sensor rod emits infrared light to the second contact piece, the system receives the infrared signal converted into an electrical signal and can detect the opening angle of the door panel. If the infrared sensor rod cannot return to the first contact piece for a long time, it means that the door panel has been opened unexpectedly and has not returned to its original position, and the system will trigger an alarm to prompt personnel to go for maintenance;

[0017] (3) By setting up a top groove, door panel and spring, since the top groove is hidden inside the machine body, the entire positioning structure will not be observed in detail by external personnel, so it is not easy to be damaged. When maintenance is required, the top groove can be opened by the cover plate at the rear of the machine body, and the components in the top groove, especially the spring, can be replaced to avoid structural failure caused by wear and tear. There is no need to replace the stainless steel spring hinge or door panel, thus reducing maintenance costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment of an automatic vending machine with a door positioning device, comprising a body 1 and a door frame 9. The door frame 9 is installed at the top front end of the body 1, and a door panel 5 is hinged to the body 1 via the door frame 9. A stainless steel spring-loaded hinge 4 is installed between the door frame 9 and the door panel 5. A top groove 2 is formed at the top inside the body 1, and a positioning structure is provided in the top groove 2. The positioning structure includes two sets of springs 10 fixed to the rear of the inner wall of the top groove 2. A movable plate 3 is fixedly mounted at the front end of the springs 10. The front end of the movable plate 3, from right to left... The left side is provided with a first damping ball 15, a second damping ball 17 and a third damping ball 19 respectively. A set of movable seats 8 is movably connected inside the door frame 9. The front end of the movable seat 8 is hinged to the door panel 5 with a telescopic rod 6. The rear end of the movable seat 8 is fixedly connected to a touch rod 21 with an infrared sensor. The touch rod 21 with an infrared sensor abuts against the movable plate 3. The first damping ball 15, the second damping ball 17 and the third damping ball 19 are all hemispherical and covered with butyl rubber. The telescopic rod 6 is a metal rod that is nested and slides with each other.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the vending machine has a positioning structure for positioning the door angle in the top groove 2. A movable seat 8 is added to the telescopic rod 6. When the telescopic rod 6 is extended as the door opens and moves the movable seat 8 from right to left, the infrared sensor touch rod 21 at the rear end of the movable seat 8 also moves from right to left at the movable plate 3. The three sets of damping balls correspond to 90°, 120° and 150° respectively. When the infrared sensor touch rod 21 touches the damping ball, it is necessary to continue to open the door panel 5 with force. When the infrared sensor touch rod 21 crosses the first damping ball 15, the presence of the spring 10 will cause the movable plate 3 to move backward, thus ensuring that the door panel 5 can be opened to the corresponding degree after a certain force is applied. If no further force is applied, the infrared sensor touch rod 21 stays between the two sets of damping balls, overcoming the rebound force of the stainless steel spring hinge 4, and the door can be positioned near the corresponding degree, thus realizing the multi-angle positioning and opening function.

[0026] A track 7 is provided in the top groove 2 along its length. A roller 22 is installed on the lower half of the rear end of the movable seat 8. The roller 22 is embedded in the track 7 and rolls. A first contact piece 14, a second contact piece 16, a third contact piece 18 and a fourth contact piece 20 are respectively provided on the front end of the movable plate 3 from right to left. The first contact piece 14, the second contact piece 16, the third contact piece 18 and the fourth contact piece 20 are distributed at intervals with the first damping ball 15, the second damping ball 17 and the third damping ball 19.

[0027] Specifically, such as Figure 1 , Figure 2 and 3 As shown, the first contact piece 14, the second contact piece 16, the third contact piece 18, and the fourth contact piece 20 are distributed at intervals with the first damping ball 15, the second damping ball 17, and the third damping ball 19. When the infrared sensor-equipped contact rod 21 crosses the first damping ball 15 and reaches the second contact piece 16, the infrared sensor-equipped contact rod 21 emits infrared rays towards the second contact piece 16. The system can detect the opening angle of the door panel 5 by receiving the electrical signal converted from the infrared signal. If the infrared sensor-equipped contact rod 21 fails to return to the first contact piece 14 for a long time, it indicates that the door panel 5 has been opened unexpectedly and has not returned to its original position. The system will trigger an alarm to prompt personnel to go for maintenance.

[0028] The inner wall of the top groove 2 has movable grooves 11 on both sides along its width direction. The movable plate 3 is respectively embedded in the movable grooves 11 and moves. The spring 10 includes a mounting piece 13 with its front end fixedly bonded to it. The mounting piece 13 and the movable plate 3 are fixedly connected by a fixing bolt 12. A removable cover plate is provided at the rear of the machine body 1. The position of the removable cover plate corresponds to the top groove 2.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, since the top groove 2 is hidden inside the body 1, the entire positioning structure cannot be observed in detail by external personnel, so it is not easily damaged. When maintenance is required, the top groove 2 can be opened through the cover plate at the rear of the body 1, and the various components inside the top groove 2, especially the spring 10, can be replaced.

[0030] Working principle: When the telescopic rod 6 extends as the door opens, it drives the movable seat 8 to move from right to left. Simultaneously, the infrared sensor-equipped contact rod 21 at the rear end of the movable seat 8 also moves from right to left at the movable plate 3. The three sets of damping balls correspond to 90°, 120°, and 150° respectively. When the infrared sensor-equipped contact rod 21 touches the damping ball, further force is needed to open the door panel 5. When the infrared sensor-equipped contact rod 21 crosses the first damping ball 15, the presence of the spring 10 causes the movable plate 3 to retract, thus ensuring that the door panel 5 can open to the corresponding degree after applying a certain force. If no further force is applied, the infrared sensor-equipped contact rod 21 remains between the two sets of damping balls, overcoming... The rebound force of the stainless steel spring hinge 4 allows the door to be positioned near the corresponding angle. The first contact piece 14, the second contact piece 16, the third contact piece 18, and the fourth contact piece 20 are distributed at intervals with the first damping ball 15, the second damping ball 17, and the third damping ball 19. When the infrared sensor contact rod 21 crosses the first damping ball 15 and reaches the second contact piece 16, the infrared sensor contact rod 21 emits infrared rays towards the second contact piece 16. The system receives the infrared signal and converts it into an electrical signal to detect the opening angle of the door panel 5. If the infrared sensor contact rod 21 fails to return to the first contact piece 14 for a long time, it indicates that the door panel 5 has been opened unexpectedly and has not returned to its original position. The system will trigger an alarm to prompt personnel to go for maintenance.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
