[0040] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0041] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0043] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0044] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0045] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0046] like Figure 1 As shown, this application embodiment provides an intelligent locker, including a main body 1, a second detection element 3, and a data acquisition unit 4. The main body 1 includes a shell 11 and a bottom plate 12, which together form a receiving cavity. One side of the bottom plate 12 is rotatably connected to the shell 11, and the other side of the bottom plate 12 is connected to the shell 11 through the second detection element 3. The data acquisition unit 4 is installed at the connection position between the bottom plate 12 and the shell 11 and is used to detect the angle of rotation of the bottom plate 12 relative to the shell 11.

[0047] The intelligent locker may include a main body 1, a second detection element 3, and a detection unit 4. The main body 1 includes a shell 11 and a base plate 12, which together form a cavity for placing an item 6. One end of the base plate 12 is connected to the shell 11 and can rotate relative to the shell 11. One end of the second detection element 3 is connected to the shell 11, and the other end is connected to the base plate 12. Specifically, when the item 6 is placed in the cavity, the base plate 12 can rotate relative to the shell 11 under the weight of the item 6. At this time, the second detection element 3 can be stretched along with the rotation of the base plate 12, applying a force to the base plate 12. Therefore, when the main body 1 and the item 6 are stationary, the weight of the item 6 and the tension of the second detection element 3 are in balance. Meanwhile, the detection unit 4 is installed on the outside of the cavity. This arrangement not only saves internal space in the cavity to accommodate the item 6 but also reduces the possibility of interference between the base plate 12 and the detection unit 4 when the base plate 12 rotates. The collection unit 4 can detect the angle of rotation of the base plate 12 relative to the housing 11, and thus calculate the tension of the second detection element 3 based on the detection result. The base plate 12 can act as a lever, and the weight of the item 6 can be calculated using the lever principle.

[0048] In existing technologies, smart lockers typically use strain gauge load cells to detect the weight of items. However, this measurement method requires each strain gauge load cell to be equipped with an analog signal processing device, which increases the production and usage costs of smart lockers.

[0049] Compared with the prior art, the smart locker provided in this application embodiment, by setting up a collection unit 4 and a second detection element 3 and using the lever principle for calculation, is conducive to realizing the weighing function of the smart locker on the item 6. This weighing method is conducive to reducing the production and use cost of the smart locker, thereby facilitating the production and application of the smart locker.

[0050] like Figure 2 and Figure 3 As shown, in one possible embodiment, the base plate 12 is provided with at least one first connecting portion 121 to serve as a rotation axis for the base plate 12 to rotate relative to the housing 11.

[0051] The base plate 12 is provided with at least one first connecting part 121. The base plate 12 is rotatably connected to the housing 11 through the first connecting part 121. Specifically, at least a portion of the first connecting part 121 can pass through the housing 11. The first connecting part 121 can be a long cylindrical shaft and can be hinged to the housing 11. The first connecting part 121 can serve as a rotation axis for the base plate 12 to rotate relative to the housing 11, that is, the base plate 12 can rotate around the axis of the first connecting part 121.

[0052] By setting the first connecting part 121, the base plate 12 can be rotatably connected to the housing 11 through the first connecting part 121, which is conducive to realizing the rotation of the base plate 12, thereby facilitating the detection function of the acquisition part 4, and further facilitating the realization of the weighing function of the smart locker.

[0053] like Figure 3 As shown, in one possible implementation, the acquisition unit 4 includes a first gear 41, a sensor 42, and a second gear 43. The first gear 41 is mounted on the first connecting part 121, the sensor 42 is mounted on the housing 11, and the sensor 42 is provided with a mounting shaft 421. The second gear 43 is connected to the sensor 42 through the mounting shaft 421, and the second gear 43 meshes with the first gear 41.

[0054] The first gear 41 is mounted on the first connecting part 121 and located outside the receiving cavity. When the first gear 41 rotates, the sensor 42 can detect the angle of rotation of the base plate 12 relative to the housing 11. The sensor 42 is mounted on the housing 11 and is provided with a mounting shaft 421. The second gear 43 can be mounted on the mounting shaft 421 and can mesh with the first gear 41. When the base plate 12 rotates, the first gear 41 can drive the second gear 43 to rotate together, so that the sensor 42 can detect the angle of rotation of the base plate 12 relative to the housing 11. Specifically, when the base plate 12 rotates, the rotation angle of the first connecting part 121 is t, the tooth ratio of the first gear 41 and the second gear 43 is a, and the angle value detected by the acquisition unit 4 is b, where b = at. The larger the value of the tooth ratio a of the first gear 41 and the second gear 43, the higher the detection accuracy of the acquisition unit 4. The detection result of the acquisition unit 4 is helpful in calculating the weight of the item 6. On the other hand, the acquisition unit 4 can also be equipped with a multi-stage gear set. Compared with a single-stage gear set, setting a multi-stage gear set can increase the value of the gear ratio a, which is beneficial to improving the detection accuracy of the acquisition unit 4, and thus beneficial to improving the detection accuracy of the weight of the item 6.

[0055] This helps improve the detection accuracy of the collection unit 4, which in turn helps improve the accuracy of the smart locker in detecting the weight of the items 6.

[0056] In one possible implementation, the second gear 43 has fewer teeth than the first gear 41. This arrangement facilitates the detection function of the acquisition unit 4 and also helps to improve the detection accuracy of the acquisition unit 4.

[0057] In one possible implementation, the housing 11 is provided with an extension 111 located outside the receiving cavity, and the bottom plate 12 is provided with at least one second connecting part 122 located on the side of the extension 111 near the bottom plate 12 and connected to the extension 111 via a second detection element 3.

[0058] The housing 11 is provided with an extension 111, which is located outside the receiving cavity and extends away from the housing 11. The base plate 12 is provided with at least one second connecting portion 122, which is located on the side of the extension 111 near the base plate 12, and at least a portion of the second connecting portion 122 is located outside the housing 11. The second detection element 3 may also be located outside the receiving cavity, with one end of the second detection element 3 connected to the extension 111 and the other end connected to the second connecting portion 122. By providing the extension 111 and the second connecting portion 122, it is beneficial for the second detection element 3 to realize its detection function, and it is also beneficial to improve the stability of the installation of the second detection element 3.

[0059] In this embodiment, the main body 1 may include two second detection elements 3 and two connecting parts 122, and the second connecting parts 122 may be located on opposite sides of the main body 1. The second detection elements 3 may be connected to the corresponding second connecting parts 122 respectively. This arrangement is beneficial to improving the stability of the base plate 12 when rotating, and at the same time, it is beneficial to improve the detection accuracy of the second detection elements 3, thereby improving the accuracy of weighing the item 6.

[0060] like Figure 4 As shown, in one possible implementation, the second detection element 3 is an elastic element, and the extension 111 is elastically connected to the second connecting part 122.

[0061] The second detection element 3 is an elastic element, specifically, it can be a spring balance. The second connecting part 122 is elastically connected to the extension part 111, that is, one end of the second detection element 3 is connected to the extension part 111, and the other end is connected to the second connecting part 122. When the article 6 is located in the receiving cavity, the second detection element 3 can undergo elastic deformation. Specifically, when the article 6 is located in the receiving cavity, under the action of the weight of the article 6, the base plate 12 will rotate relative to the shell 11. Since the second detection element 3 is an elastic element, the base plate 12 can drive the second detection element 3 to move. That is, under the action of the base plate 12, the second detection element 3 can undergo elastic deformation, and the second detection element 3 also applies a force to the base plate 12. When the main body 1 and the item 6 are stationary, the force exerted by the second detection element 3 on the base plate 12 is balanced with the force exerted by the box on the base plate 12. Since the second detection element 3 can measure the magnitude of the force exerted on the base plate 12 by Hooke's Law, specifically, when the main body 1 is unloaded, the force exerted by the second detection element 3 is kl0, where k is the spring stiffness of the second detection element 3 and l0 is the original length of the second elastic element. When the item 6 is located in the receiving cavity of the main body 1, the base plate 12 rotates, and the second detection element 3 undergoes elastic deformation. At this time, the force exerted by the second detection element 3 is kl1, where k is the spring stiffness of the second detection element 3 and l1 is the length of the second detection element 3 after elastic deformation. The value of l1 can be obtained by the measurement of the acquisition unit 4. Thus, according to the lever principle and the principle of mechanical balance, the processor can calculate the weight of the item 6 by the detection result of the second detection element 3.

[0062] This setup facilitates the use of the lever principle to measure the weight of item 6, reduces the likelihood of using strain gauge load cells to weigh item 6, thereby lowering the production and usage costs of the smart locker. It also improves the measurement accuracy of the second detection element 3, and consequently enhances the accuracy of weight detection for item 6.

[0063] like Figure 4 As shown, in one possible implementation, the smart locker also includes a first detection element 2. The top wall of the housing 11 has an installation groove 112, and the first detection element 2 is installed in the installation groove 112 to detect the height of the item 6 in the storage cavity.

[0064] The top wall of the housing 11 has a mounting groove 112, specifically, the mounting groove 112 can be located at the center of the top wall. A first detection element 2 can be installed in the mounting groove 112. The height of the item 6 can be detected by the first detection element 2. Typically, items 6 of different sizes have the same length and width. Therefore, when the first detection element 2 detects the height of the item 6, the smart locker can calculate the volume of the item 6 through its processor. In existing technology, camera equipment is typically used to measure the volume of items, and this measurement needs to be performed during transport. Therefore, it is impossible to measure the weight and volume of items simultaneously. Camera equipment is affected by factors such as performance, information acquisition volume, and item transmission rate, resulting in low measurement speed and accuracy. It cannot measure multiple items simultaneously, and using camera equipment further increases the operating cost of the smart locker.

[0065] Compared to existing technologies, the embodiments of this application, by setting the first detection element 2, facilitate the measurement of the height of the item 6, thereby facilitating the detection of the volume of the item 6 and ultimately determining its specific specifications. Compared to using a camera device to measure the volume of the item 6, using the first detection element 2 reduces the cost of measuring the volume of the item 6, and also improves the measurement speed and accuracy, thus reducing usage costs.

[0066] like Figure 2 As shown, in one possible implementation, the smart locker also includes a third detection element 5, which is located on the side of the base plate 12 away from the second detection element 3. The third detection element 5 is used to detect the position of the item 6 in the storage cavity relative to the base plate 12.

[0067] The smart locker may also include a third detection element 5, which is located on the side of the base plate 12 away from the second detection element 3, that is, the third detection element 5 is located on the side where the base plate 12 is rotatably connected to the housing 11. The third detection element 5 is used to detect the position of the center of gravity of the item 6 relative to the base plate 12. Specifically, along the width direction of the main body, the third detection element 5 can measure the distance D from the side of the item 6 close to the third detection element 5 to the axis of the first connecting part 121. Therefore, the position of the center of gravity of the item 6 relative to the base plate 12 can be detected by the third detection element 5. Based on the position of the center of gravity of the item 6, the weight of the item 6 can be calculated according to the mechanical balance and lever principle.

[0068] This setup facilitates the use of lever principles and mechanical balance principles to measure the weight of item 6, reducing the likelihood of using strain gauge load cells to weigh item 6, thereby reducing the production and usage costs of the smart locker.

[0069] In one possible implementation, the smart locker can be equipped with multiple main body sections 1.

[0070] The smart locker can be equipped with multiple main bodies 1, each capable of weighing and measuring the volume of items 6. This facilitates large-scale inspection of the smart locker and improves inspection efficiency. The smart locker can also be applied to smart devices, such as drone delivery and pickup systems and automated parcel lockers. By incorporating multiple main bodies 1, the working efficiency of the smart locker is enhanced, thereby improving the overall efficiency of the smart devices.

[0071] In one possible implementation, both the first detection element 2 and the third detection element 5 are ultrasonic probes.

[0072] Both the first detection component 2 and the third detection component 5 can be ultrasonic probes. These probes can emit and receive ultrasonic waves, enabling the detection function. Compared to existing technologies, using ultrasonic probes not only reduces the production cost of smart lockers, but also allows for simultaneous measurement of the volume and weight of the item 6, thereby improving the detection speed and efficiency of the smart locker.

[0073] In one possible embodiment, the smart locker also includes a processor for processing data acquired from one or more of the first detector 2, the second detector 3, the third detector 5, and the acquisition unit 4.

[0074] like Figure 5 As shown, the intelligent locker is equipped with a processor, which may include a control unit, an analog-to-digital converter, and a peripheral interface. The processor receives detection data from the acquisition unit 4 via the analog-to-digital converter and connects to the first detection element 2 and the third detection element 5 via the peripheral interface. Thus, the processor can receive detection data from one or more of the first detection element 2, the second detection element 3, the third detection element 5, and the acquisition unit 4, and perform calculations on it. The specific method is as follows:

[0075] like Figure 6 As shown, the base of a smart locker is usually rectangular, therefore Figure 6 In this context, the Y direction corresponds to the width of the base plate 12, and the X direction corresponds to its length. Given that the width of item 6 is W, its weight is G, and its center of gravity is located at its geometric center, and given that the width of the base plate 12 is L, its weight is T, and its center is also located at its geometric center, then according to the principle of mechanical equilibrium, when the main body 1 is unloaded, the force equilibrium equation of the base plate 12 is:

[0076]

[0077] When item 6 is placed into the receiving cavity, the second detection element 3 undergoes elastic deformation. At this time, the force balance equation of the base plate 12 is:

[0078]

[0079] The angle of the first connecting part 121 is t. Since the value of t is small, it can be approximated based on geometric conditions:

[0080]

[0081] Furthermore, based on b = at, we can deduce and ultimately obtain the expression for the weight G of item 6:

[0082]

[0083]

[0084] In the above expression, the spring stiffness of the second detection element 3 is known to be k, the width of the item 6 is W, the width of the base plate 12 is L, the weight of the base plate 12 is T, the tooth ratio of the collection unit 4 is a, and b is the detection data of the collection unit 4, and D is the detection data of the third detection element 5. Thus, the processor can calculate the weight G of the item 6 according to the above expression.

[0085] The weight and volume of item 6 can be measured by the combined action of the second detection element 3, the third detection element 5 and the acquisition unit 4. Compared with the strain gauge type weighing sensor used in the prior art, the embodiment of this application is conducive to reducing the measurement cost of smart lockers, thereby facilitating the batch measurement and weighing of smart lockers, and further improving the measurement efficiency of smart lockers.

[0086] This application provides an intelligent locker, including a main body 1, a second detection element 3, and a data acquisition unit 4. The main body 1 includes a shell 11 and a base plate 12, which together form a receiving cavity. One side of the base plate 12 is rotatably connected to the shell 11, and the other side of the base plate 12 is connected to the shell 11 via the second detection element 3. The data acquisition unit 4 is installed at the connection point between the base plate 12 and the shell 11 and is used to detect the angle of rotation of the base plate 12 relative to the shell 11. By employing the lever principle and incorporating the data acquisition unit 4 and the second detection element 3, this application facilitates the weighing function of the intelligent locker on items 6. This weighing method helps reduce the production and usage costs of the intelligent locker, thereby promoting its production and application.

[0087] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
