Description

Technical Field

[0001] This utility model relates to the field of weighing technology, and more specifically, to a weighing device. Background Technology

[0002] For weighing equipment with interactive components and sensors, the area where the interactive components are located is usually not designed to place the object being weighed. Therefore, the sensors are usually not placed in the same area as the interactive components. This results in the weighing equipment having a non-compact and non-lightweight structure. Moreover, all the sensors cannot be evenly stressed, leading to inaccurate weighing.

[0003] Therefore, how to provide a compact, lightweight, and accurate weighing device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0041] 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.

[0042] The core of this utility model is to provide a weighing device that is compact, lightweight, and accurate in weighing.

[0043] It should be noted that in this embodiment, the orientations or positional relationships indicated by terms such as "up," "down," "left," and "right" are based on the orientations or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, "first," "second," and "third" are used only to describe effects and should not be construed as indicating or implying relative importance.

[0044] Please refer to Figure 1 This application provides a weighing device, including a face shell 1, an interaction component 2, a support plate 5, a flat plate 6, and a first sensor 10.

[0045] Interactive component 2 is placed on shell 1.

[0046] The support plate 5 is located below the interactive component 2, and the support plate 5 has a first notch 51 located below the interactive component 2.

[0047] The plate 6 is located on the side of the support plate 5 facing away from the shell 1. The plate 6 is provided with a limiting hole 61, which is connected to the first notch 51.

[0048] The first sensor 10 is located on the side of the plate 6 facing away from the support plate 5. At least a portion of the strain gauges 12 of the first sensor 10 are positioned facing the limiting hole 61 and can deform through the limiting hole 61 in the first notch 51.

[0049] It should be noted that the interactive component 2 can be a separate touch panel for users to perform corresponding operations by touch input, or a separate display screen for displaying numbers, images and other content, or a touch display screen that integrates touch and display functions.

[0050] The interactive component 2 is located on the back of the faceplate 1. An elastic support 3 is provided on the side of the interactive component 2 facing away from the faceplate 1. The elastic support 3 abuts against the support plate 5. While supporting the interactive component 2, the elastic support 3 also isolates the interactive component 2 from the support plate 5 to prevent the support plate 5 from squeezing and damaging the interactive component 2. The elastic support 3 can be made of foam or rubber pad.

[0051] The support plate 5 not only serves to fix and install the plate 6, the first sensor 10, or other electrical components (such as the battery 9 and the charging plate 8), but also serves to balance the weight of the object and transmit it to each sensor. Thus, the support plate 5 is made of high structural strength material, which makes the support plate 5 have a strong load-bearing capacity and is not easy to deform, thereby better supporting the parts and balancing the weight of the object.

[0052] It should also be noted that during weighing, the weight of the object causes the strain gauge of the sensor to undergo elastic deformation. The degree of deformation of the strain gauge is proportional to the weight of the object. The strain gauge deformation is converted into an electrical signal by a physical mechanism, and after amplification, filtering, and digital processing, it is output to the interactive component 2. Therefore, the support plate 5 is provided with a first notch 51, and the plate 6 is provided with a limiting hole 61. The limiting hole 61 and the first notch 51 are connected and are located below the interactive component 2. The first sensor 10 below the interactive component 2 is located on the side of the plate 6 facing away from the support plate 5. At least part of the strain gauge 12 of the first sensor 10 faces the limiting hole 61 and can deform through the limiting hole 61 in the first notch 51. This can prevent the support plate 5 from blocking the deformation of the strain gauge and affecting the sensor detection results, thus ensuring the accuracy of weighing.

[0053] The weighing equipment provided in the above embodiments has the following beneficial effects:

[0054] First, the interactive component 2 is located on the face shell 1, and a support plate 5 is provided below the interactive component 2. A flat plate 6 is provided on the side of the support plate 5 facing away from the face shell 1. Even if the flat plate 6 is placed below the interactive component 2, the first sensor 10 below the interactive component 2 can be installed on the side of the flat plate 6 facing away from the support plate 5, so as to avoid mutual interference between the interactive component 2 and the first sensor 10 below it during installation. This allows the first sensor 10 to be arranged below the interactive component 2, making the internal structure of the weighing equipment compact, small and lightweight.

[0055] Second, a flat plate 6 is provided on the side of the support plate 5 facing away from the shell 1, and a first sensor 10 is provided on the side of the flat plate 6 facing away from the support plate 5. Even if the support plate 5 is placed between the shell 1 and the first sensor 10, when an object is placed on the shell 1 for weighing, the support plate 5 can balance the weight of the object and transmit it to the first sensor 10, so that the sensor of the weighing device is evenly stressed and the weighing accuracy is ensured.

[0056] Third, the support plate 5 is provided with a first notch 51, which is located below the interactive component 2. The plate 6 is provided with a limiting hole 61, which is connected to the first notch 51. The strain gauge 12 of the first sensor 10 faces the limiting hole 61. After the first sensor 10 is deformed by force, at least part of the strain gauge of the first sensor 10 can deform in the first notch 51. This can prevent the support plate 5 from blocking the deformation of the strain gauge 12 and affecting the sensor detection result, thus ensuring the accuracy of weighing.

[0057] Based on the above embodiments, please refer to Figure 2 The first sensor 10 also includes a first support part 101, which is connected to the strain gauge 12 in the first sensor 10; a first buckle 62 is provided on the side of the plate 6 facing away from the support plate 5. The first buckle 62 is arranged on the outer periphery of the limiting hole 61. The first buckle 62 abuts against the first support part 101 and fixes the first support part 101 to the side of the plate 6 facing away from the support plate 5.

[0058] Specifically, the first support portion 101 serves as a support structure for the first sensor 10, supporting the connected strain gauge 12. A first buckle 62 is provided on the side of the plate 6 facing away from the support plate 5. The first buckle 62 is arranged on the outer periphery of the limiting hole 61. The first buckle 62 abuts against the first support portion 101 in the first sensor 10, fixing the first support portion 101 to the side of the plate 6 facing away from the support plate 5 and located below the limiting hole 61. At least a portion of the strain gauge 12 connected to the first support portion 101 faces the limiting hole 61.

[0059] As can be seen from the above structure, the first sensor 10 is fixed to the side of the plate 6 facing away from the support plate 5 using the first buckle 62. Compared with conventional fasteners such as bolts, the assembly method is simple and the first sensor 10 is easy to install and remove. In addition, the first buckle 62 abuts against the first support part 101 in the first sensor 10 and presses the first support part 101 tightly onto the plate 6, so that the first support part 101 and the plate 6 are in close contact. After the weight of the object is balanced by the support plate 5, it can be effectively transmitted to the first support part 101 through the plate 6. The first support part 101 then acts the weight in the opposite direction on the strain gauge 12, so that the deformation degree of the strain gauge 12 accurately reflects the weight of the object, thereby ensuring the accuracy of weighing.

[0060] At least two first buckles 62 are provided, and the at least two first buckles 62 are evenly arranged on the outer periphery of the limiting hole 61 to improve the stability of the first sensor 10 installation.

[0061] Based on the above embodiments, please refer to Figure 2 The weighing equipment also includes a circuit board 7, which is located on the side of the plate 6 facing away from the support plate 5. A second buckle 63 is provided on the side of the plate 6 facing away from the support plate 5. The second buckle 63 abuts against the circuit board 7 and fixes the circuit board 7 to the side of the plate 6 facing away from the support plate 5.

[0062] As can be seen from the above structure, using the second clip 63 to fix the circuit board 7 to the side of the flat plate 6 facing away from the support plate 5 has the following effects: on the one hand, it can make full use of the setting space on the side of the flat plate 6 facing away from the support plate 5, so that the circuit board 7 and the first sensor 10 are compactly set, thereby improving the compactness of the internal structure of the weighing equipment; on the other hand, compared with conventional fasteners such as bolts, using the second clip 63 to fix the circuit board 7 is simple to assemble and convenient to disassemble and assemble the circuit board 7.

[0063] At least two second clips 63 are provided, and the at least two second clips 63 are evenly arranged around the circuit board 7 to improve the stability of the circuit board 7 installation.

[0064] It should also be noted that circuit board 7 is responsible for receiving and processing the weight signals from the sensors. When an object is placed on the faceplate 1, the sensors convert the weight into electrical signals, which are then received and processed by circuit board 7. Finally, the signals are transmitted to the interactive component 2 to display the accurate weight of the object. Thus, as... Figures 1-3 As shown, the interactive component 2 is connected to the connector 4, and the connector 4 passes through the socket 55 in the support plate 5 to connect to the circuit board 7, so as to realize the signal interaction between the interactive component 2 and the circuit board 7. Moreover, the first sensor 10 is connected to the circuit board 7 through the signal, so as to realize the signal interaction between the first sensor 10 and the circuit board 7.

[0065] Based on the above embodiments, please refer to Figure 2The area of ​​the plate 6 is smaller than the area of ​​the support plate 5; the weighing device also includes a second sensor 11, which is located on the side of the support plate 5 facing away from the shell 1; the support plate 5 is provided with a second notch 52, and at least a portion of the strain gauges 12 of the second sensor 11 are arranged toward the second notch 52 and can deform in the second notch 52.

[0066] Specifically, the area of ​​the plate 6 is smaller than that of the support plate 5, so that the plate 6 does not need to cover the side of the support plate 5 facing away from the faceplate 1. The plate 6 only needs to be located below the interaction component 2 to fix the first sensor 10 below the interaction component 2. This arrangement facilitates the processing of the plate 6 and saves on the processing cost of the plate 6. On the other hand, since the circuit board 7 is fixed on the plate 6, the circuit board 7 and the first sensor 10 can be concentrated below the interaction component 2, thereby further improving the compactness of the internal structure of the weighing equipment.

[0067] A second sensor 11 is also provided on the side of the support plate 5 facing away from the shell 1. The second sensor 11 and the first sensor 10 work simultaneously, which can more effectively distribute the weight of the object and improve the accuracy of weighing. In addition, the support plate 5 is provided with a second notch 52. At least part of the strain gauge 12 of the second sensor 11 is arranged facing the second notch 52 and can deform in the second notch 52. This can prevent the support plate 5 from blocking the deformation of the strain gauge 12 and affecting the sensor detection results, thus ensuring the accuracy of weighing.

[0068] Based on the above embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The second sensor 11 also includes a second support part 111, which is connected to the strain gauge 12 in the second sensor 11; the support plate 5 is provided with an insertion hole 53, which is arranged on the outer periphery of the second notch 52, and the third buckle 15 on the face shell 1 passes through the insertion hole 53 and abuts against the second support part 111 and fixes the second support part 111 to the side of the support plate 5 facing away from the face shell 1.

[0069] Specifically, the second support part 111 serves as a support structure for the second sensor 11, used to support and connect the strain gauge 12. The support plate 5 is provided with an insertion hole 53, which is arranged on the outer periphery of the second notch 52. The face shell 1 is provided with a third buckle 15 at the position corresponding to the insertion hole 53. The third buckle 15 passes through the insertion hole 53 and abuts against the second support part 111, which can fix the second support part 111 to the side of the support plate 5 facing away from the face shell 1.

[0070] As can be seen from the above structure, the second sensor 11 is fixed to the side of the support plate 5 facing away from the face shell 1 by the third buckle 15. Compared with conventional fasteners such as bolts, the assembly method is simple and the second sensor 11 is easy to install and remove. In addition, the third buckle 15 abuts against the second support part 111 in the second sensor 11 and presses the second support part 111 tightly onto the support plate 5, so that the second support part 111 and the support plate 5 are in close contact. After the weight of the object is balanced by the support plate 5, it can be effectively transmitted to the second support part 111 through the support plate 5. The second support part 111 then acts the weight in the opposite direction on the strain gauge 12, so that the deformation degree of the strain gauge 12 accurately reflects the weight of the object, thereby ensuring the accuracy of weighing.

[0071] Please refer to Figure 5 The third latch 15 includes a support rod 151 and a latching block 152. The support rod 151 is vertically mounted on the face shell 1, and the end of the support rod 151 away from the face shell 1 is connected to the latching block 152. The latching block 152 passes through the insertion hole 53 of the support plate 5 and abuts against the second support part 111 in the second sensor 11. With the above-described structure, the third latch 15 not only secures the second sensor 11, but the vertical support rod 151 in the third latch 15 also serves as a guide when assembling the support plate 5, facilitating the proper assembly of the support plate 5.

[0072] Based on the above embodiments, please refer to Figure 2 The support plate 5 has multiple blocks 54 on the side facing away from the shell 1. The multiple blocks 54 surround the outer periphery of the second sensor 11, thereby effectively limiting the offset of the second sensor 11.

[0073] Based on the above embodiments, please refer to Figure 1 and Figure 3 A first notch 51 is provided at one or two corners of the support plate 5 in the width direction, and a second notch 52 is provided at the remaining corners of the support plate 5.

[0074] Specifically, a first notch 51 is provided at one or two corners along the width direction of the support plate 5. Since the plate 6 has a limiting hole 61 communicating with the first notch 51, the plate 6 is provided at one or two corners along the width direction of the support plate 5. Furthermore, since the first sensor 10 is provided on the plate 6, and at least a portion of the strain gauge 12 of the first sensor 10 faces the limiting hole 51, it is easy to conclude that the first sensor 10 is provided at one or two corners along the width direction of the support plate 5. Additionally, a second notch 52 is provided at the remaining corners of the support plate 5. Since the second sensor 11 is provided on the support plate 5, and at least a portion of the strain gauge 12 of the second sensor 11 faces the second notch 52, it is easy to conclude that the second sensor 11 is provided at the remaining corners of the support plate 5. Thus, sensors are provided at all four corners of the support plate 5. During weighing, regardless of where the object is placed on the shell 1, the object's weight can be evenly distributed to the four sensors, thereby improving the accuracy of weighing.

[0075] In addition, the plate 6 is positioned at one or two corners of the support plate 5 in the width direction. Since the interactive component 2 is located above the plate 6 and the circuit board 7 is located on the plate 6, the interactive component 2 and the circuit board 7 can be concentrated inside one side of the weighing equipment in the width direction, making full use of the space in the width direction and making the internal structure of the weighing equipment more compact.

[0076] Based on the above embodiments, please refer to Figure 1 and Figure 4 The faceplate 1 is divided into a display area 17 and a weighing area 18 along its length. The display area 17 is located on the left side of the faceplate 1, and the weighing area 18 is located on the right side of the faceplate 1. The weighing device also includes a battery 9, which is located on the side of the support plate 5 facing away from the faceplate 1. Along the direction of gravity, the support plate 5 is located below the display area 17 and the weighing area 18, the flat plate 6 is located below the display area 17, and the battery 9 is located below the weighing area 18.

[0077] Specifically, the faceplate 1 is divided into a display area 17 and a weighing area 18 along its length. The display area 17 is mainly used to display weighing data, and the weighing area 18 is mainly used to place objects for weighing. The support plate 5 is located below the display area 17 and the weighing area 18, and the flat plate 6 is located below the display area 17. Since the interactive component 2 is located between the faceplate 1 and the support plate 5, and the circuit board 7 is located on the side of the flat plate 6 facing away from the faceplate 1, the interactive component 2 and the circuit board 7 are sequentially located below the display area 17 along the direction of gravity. The battery 9 is located in the weighing area 18, which can reduce the thickness of the display area 17, thereby reducing the overall thickness of the weighing device.

[0078] In addition, the interactive component 2 below the display area 17 can be connected to other devices (such as mobile phones) for information interaction. Thus, the display area 17 is located on the left side of the faceplate 1, and the weighing area 18 is located on the right side of the faceplate 1, which makes it convenient for the user to operate the mobile phone with their right hand and operate the interactive component 2 in the weighing device with their left hand.

[0079] For specific instructions on how to install battery 9, please refer to [link / reference needed]. Figures 1-3 A battery slot 56 is provided on the support plate 5 located below the weighing area 18. The battery slot 56 is snapped into place with the battery 9, making it easy for the battery 9 to be installed on the support plate 5.

[0080] Based on the above embodiments, the plate 6 is made of insulating material, such as a plastic plate or a resin plate. The plate 6 is made of insulating material to avoid the risk of short circuit caused by contact between the plate 6 and the circuit board 7.

[0081] Based on the above embodiments, please refer to Figure 1 The weighing device also includes a bottom shell 14 and a support leg 13. The bottom shell 14 and the top shell 1 are fastened together to form an accommodating space. The support leg 13 is installed through the bottom shell 14. The first sensor 10 and the second sensor 11 are located in the accommodating space and their strain gauges 12 are installed on different support legs 13.

[0082] Specifically, the periphery of the front shell 1 is provided with multiple first snap-fit ​​parts, and the periphery of the bottom shell 14 is provided with multiple second snap-fit ​​parts. The multiple first snap-fit ​​parts and multiple second snap-fit ​​parts are connected one-to-one, so that the bottom shell 14 and the front shell 1 are fastened together. This assembly method facilitates disassembly and assembly. Furthermore, an accommodating space is formed between the bottom shell 14 and the front shell 1, in which the interactive component 2, the support plate 5, the flat plate 6, the circuit board 7, the battery 9, the first sensor 10, and the second sensor 11 are all placed.

[0083] The bottom shell 14 has through holes 141 at the positions corresponding to the first sensor 10 and the second sensor 11. The support legs 13 pass through the bottom shell 14 through the through holes 141 and extend out of the accommodating space to support the weighing equipment. Moreover, the strain gauges 12 in the first sensor 10 and the second sensor 11 are installed on different support legs 13, so that the strain gauges 12 make full use of the internal space of the support legs 13, which helps to reduce the thickness of the weighing equipment.

[0084] It should also be noted that, such as Figure 6As shown, the first support part 101 of the first sensor 10 is connected to a support leg 13, and the second support part 111 of the second sensor 11 is connected to a support leg 13. Thus, during weighing, each sensor is stably in contact with the ground or support platform via the support leg 13. The weight of the object is evenly transmitted to the support parts of each sensor through the support plate 5. That is, the support plate 5 presses down on the support parts of each sensor. Since the support parts and the support legs 13 are integrated, the support legs 13 press down on the ground or support platform, and the support legs 13 receive an upward reaction force. Furthermore, the support legs 13 are connected to the strain gauges 12 in each sensor. The strain gauges 12 move upward and deform. The weighing equipment can determine the mass of the object by measuring the deformation of the strain gauges.
