Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a weighing device capable of measuring the length, width and height of an object. Background Art

[0002] With the development of society, the circulation of goods is accelerating, which has also promoted the development of the logistics sector. Currently, goods are generally transported through logistics, express delivery, and other means. Before goods enter transportation, information such as weight, three-dimensional dimensions, and barcodes are generally registered to facilitate product management. Current goods are generally transported with protective structures such as cartons, packaging bags, and even wooden boxes, resulting in a relatively regular overall structure. Currently, the registration of various information for express delivery goods is largely done manually. For example, entering barcode information is relatively simple, requiring workers to scan with a scanner or a special mobile phone. However, measuring the weight and three-dimensional dimensions of goods requires separate and cumbersome operations. Furthermore, different measurement tools are required, which poses significant limitations.

[0003] To address this issue, patent publication number CN102466511A discloses an electronic scale capable of measuring object dimensions. This scale is capable of measuring both the weight and the three-dimensional dimensions of an object. However, this patent employs three measuring blocks to measure the three-dimensional dimensions of an object, each mounted on a column. The placement of the columns restricts the placement of objects on the scale pan, making it difficult to place or retrieve items. Furthermore, the columns are prone to collision and damage during use, and their upright structure occupies space during use and transportation. Utility Model Content

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.

[0032] Reference Figures 1 to 5 The weighing device shown in the figure can measure the length, width and height dimensions of an object, including a frame 10, a weighing platform 20, two sets of horizontal measuring mechanisms 30 and a height measuring mechanism 40; the weighing platform 20 is installed on the frame 10; the two sets of horizontal measuring mechanisms 30 are respectively installed on the outer areas of the frame 10 located on two adjacent sides of the weighing platform 20; one end of the height measuring mechanism 40 is hinged to the frame 10, and the height measuring mechanism 40 and the weighing platform 20 are arranged on the same side. The height measuring mechanism 40 can swing around the hinge point and be stored and fit on the frame 10.

[0033] Specifically, in the present application, the two sets of horizontal measuring mechanisms 30 can be fixed on the frame 10 or can be designed to be able to rise and fall. The purpose is to ensure that during routine measurements, the entire weighing platform 20 has a maximum of three sides that are unobstructed, making it easier for staff to pick up and place items. It should be noted that in the actual measurement process, the horizontal measuring mechanism 30 measures the size of the corresponding side of the item from the side, preferably using non-contact measurement, which can be traditional ultrasonic measurement, laser measurement, etc. In the present application, the horizontal measuring mechanism 30 can also use conventional size measurement, and determine the distance by manual visual inspection based on a ruler. In addition, the measurement principle of the height measuring mechanism 40 is similar to that of the horizontal measuring mechanism 30. Such a structural design facilitates later maintenance and replacement of components.

[0034] This weighing device capable of measuring the length, width, and height of an item is improved upon the existing weighing platform 20 by adding two sets of horizontal measuring mechanisms 30. Since express deliveries or items are placed directly on the weighing platform 20, the two sets of horizontal measuring mechanisms 30 can be used to measure the projected dimensions of the items on the horizontal plane. The height measuring mechanism 40 adopts a retractable structural design. In addition to ensuring normal height measurement of items, it can also be retracted when not in use, reducing occupied space and facilitating the subsequent transportation of the entire weighing device. This also effectively protects the height measuring mechanism 40.

[0035] See also Figure 1 、 Figure 2 and Figure 5 As shown, in order to facilitate operation and understanding of measured data, an operation panel 16 and a display screen 17 are provided on the frame 10, and a battery 18 and a control board 19 are provided inside the frame 10. The operation panel 16 and the display screen 17 are both electrically connected to the control board 19, and the control board 19 is electrically connected to the weighing platform 20, two sets of level measuring mechanisms 30, and a height measuring mechanism 40. The battery 18 supplies power to the control board 19. The two sets of level measuring mechanisms 30 respectively measure the length and width of the object, and the height measuring mechanism 40 measures the height of the object. After the weighing platform measures the weight of the object, the measured data is sent to the display screen 17 through the control board 19 for display, so that people can intuitively understand the length, width, height and weight of the object. The transmission, processing and display principles of the above-mentioned measurement data are conventional and mature designs, and this application will not elaborate on them here.

[0036] In some possible implementation methods, in order to facilitate data interaction with external terminals and realize measurement data management, a wireless communication module 15 is provided in the frame 10, and the wireless communication module 15 is electrically connected to the control board 19. The control board 19 can send the measured length, width, height and weight data of the object to the PC or mobile terminal through the wireless communication module 15.

[0037] See also Figures 1 to 3 As shown, each horizontal measuring mechanism 30 includes a mounting shell 31, a horizontal laser ranging sensor 32 and a protective glass 33. The mounting shell 31 is mounted on the corresponding side area of ​​the frame 10 located on the periphery of the weighing platform 20. An opening is provided on the side of the mounting shell 31 close to the weighing platform 20. The protective glass 33 seals the opening. The horizontal laser ranging sensor 32 is mounted in the mounting shell 31.

[0038] The installation between the mounting shell 31 and the frame 10 can be a direct installation or a movable installation, that is, the mounting shell 31 is fixedly mounted on the corresponding area of ​​the frame 10, or is installed through a telescopic structure. In normal use, since the surface of the object is relatively regular, the horizontal measuring mechanism 30 of the frame 10 located on both sides of the weighing platform 20 can perform contactless measurement while the object is placed on the weighing platform 20 for weighing. When the mounting shell 31 and the frame 10 are fixedly mounted, in order to avoid forming an excessively large step that is not conducive to the flat placement of the object, in one embodiment, the top of the mounting shell 31 is 3-5 mm higher than the weighing plane of the weighing platform 20, and an avoidance gap is provided on the side of the frame 10 close to the protective glass 33 to facilitate measurement by the horizontal laser ranging sensor 32.

[0039] It should be noted that if the object is not properly positioned on the weighing platform 20, that is, its length and width are not parallel or approximately parallel to the two horizontal measuring mechanisms 30, two points on the same side of the object can be arbitrarily selected to transmit lasers and receive the reflected light signals. The time difference between the two can be used to measure the angle of the corresponding side of the object relative to the installation reference plane of the horizontal laser ranging sensor 32. The actual length and width of the object can then be calculated by converting the angle using trigonometric functions. In fact, this technology is a conventional and mature technical solution. For example, patents CN110146023A - Aluminum Template Length Laser Detection, CN118089553A - Laser Width Measurement Method and Device, CN101680744A - Length Measurement Device, etc. can be used. The applicant will not elaborate on these technical solutions here.

[0040] See also Figure 3 As shown, the frame 10 is provided with a mounting slot 11, a telescopic rod 12 is provided at the bottom of the mounting slot 11, and a mounting housing 31 is mounted on the upper end of the telescopic rod 12. The mounting housing 31 can be retracted into the mounting slot 11. This design allows the leveling mechanism 30 to be stored in the mounting slot 11 when not in use, facilitating subsequent transportation or storage.

[0041] See also Figures 1 to 3As shown, the height measurement mechanism 40 includes a mounting arm 41, a height laser ranging sensor 42, and a transparent glass 43. One end of the mounting arm 41 is mounted to the frame 10 via an articulated seat 45. The mounting arm 41 is provided with an open mounting cavity, and the height laser ranging sensor 42 is disposed within the cavity. The transparent glass 43 blocks the opening of the cavity. Furthermore, to prevent an object from being too close to the mounting arm 41, which would prevent the height laser ranging sensor 42 from accurately measuring, two height laser ranging sensors 42 are provided within the mounting arm 41 in this embodiment. One is located near the middle of the mounting arm 41 at each end. This allows the two height laser ranging sensors 42 to work together to perform measurements, improving measurement accuracy.

[0042] Of course, in some embodiments, the height laser ranging sensor 42 can be replaced with infrared measurement. That is, a number of infrared reflection sensors are arranged at equal intervals along the length of the mounting arm 41. That is, the mounting arm 41 continuously emits infrared rays horizontally along its length. After the infrared rays come into contact with the object, they are reflected. There must be a number of consecutive infrared reflection sensors that receive the infrared rays. The control board 19 can then determine the height of the object based on the number of infrared reflection sensors that receive the reflected infrared rays. Alternatively, a grating ranging sensor can be used, that is, the size of the measured surface of the object is determined by the number of gratings blocked. However, this design requires that the side of the object be parallel to the mounting surface of the grating ranging sensor, which has relatively high requirements for the placement of the object.

[0043] In the above embodiment, in order to facilitate the storage of the mounting arm 41, a receiving groove 13 is provided on the frame 10, and the hinge seat 45 is installed at one end of the receiving groove 13. The mounting arm 41 can rotate around the hinge seat 45 and be stored in the receiving groove 13, which is convenient for packaging and transportation.

[0044] In the above-mentioned improved embodiment, in order to prevent the mounting arm 41 from falling out of the accommodating groove 13 during transportation or storage, a clamping block 14 is provided on the side wall of the accommodating groove 13, and a clamping groove 44 for cooperating with the clamping block 14 is provided on the outer side of the mounting arm 41.

[0045] See also Figure 4 As shown, in order to facilitate the protection of the weighing platform 20, the leveling mechanism 30, and the height measuring mechanism 40 during transportation or storage, the present application further includes a protective cover 50. The protective cover 50 is snap-fitted onto the side of the frame 10 where the weighing platform 20 is provided. The protective cover 50 can cover the weighing platform 20, the two sets of leveling mechanisms 30, and the folded and stored height measuring mechanism 40. The protective cover 50 is provided with a buckle edge 51 that can cooperate with a latch edge on the frame 10.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
