Technical Field
[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a luggage box balance detection device. Background Art
[0002] As an essential tool for travel, the optimization of the design and function of suitcases has always been the focus of the travel goods industry. In recent years, with the advancement of technology and the improvement of consumers' requirements for travel experience, the design of suitcases is no longer limited to traditional carrying and storage functions, but is developing in the direction of intelligence and humanization. Among them, the balance detection of suitcases has become one of the key links to improve user experience. Traditionally, the balance of suitcases mainly depends on the intuitive judgment of factory workers or simple physical structure design, such as the distribution of wheels at the bottom and the uniform distribution of box materials. However, this experience-based method has certain limitations and subjectivity, and it is difficult to ensure the stability and safety of suitcases under different loading conditions.
[0003] Although there are some preliminary attempts to use sensor technology to monitor the balance of suitcases in the current market, most of these solutions focus on weight detection and ignore the dynamic balance control of the suitcase in a tilted state. For example, some smart suitcases have built-in weighing sensors that can only provide static weight information and cannot provide real-time feedback on the changes in the center of gravity of the suitcase during movement, especially when walking up and down slopes or on uneven roads. Therefore, how to achieve comprehensive monitoring of the balance of the inside and outside of the suitcase when it is tilted and moving has become an urgent problem to be solved, so we propose a suitcase balance detection device. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a suitcase balance detection device, which uses a tilting posture to simulate whether the suitcase is balanced during actual use, and uses the first motor of the pressure detection device to drive the wheels of the suitcase and the pressure sensor to detect the pressure to detect whether it is balanced, thereby improving the detection efficiency.
[0005] The utility model is implemented as follows: a luggage box balance detection device comprises a frame, a vertical plate is welded on the upper part of the frame, a plurality of jacks are opened on the vertical plate, a limit rod is inserted inside the jack, a bending portion is provided at one end of the limit rod, two pressure detection devices are provided on the upper part of the frame, the pressure detection devices comprise a frame, a support wheel is rotatably connected inside the frame, a first motor for driving the support wheel to rotate is fixedly connected to one side of the frame, and a pressure sensor is fixedly connected to the lower part of the frame.

DETAILED DESCRIPTION
[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0023] like Figures 1 to 5 As shown, a luggage box balance detection device provided by an embodiment of the utility model includes a frame 6, a vertical plate 4 is welded on the upper part of the frame 6, a plurality of sockets 3 are opened on the vertical plate 4, a limit rod 2 is inserted inside the socket 3, a bending portion is provided at one end of the limit rod 2, and two pressure detection devices 9 are provided on the upper part of the frame 6. The pressure detection device 9 includes a frame 91, a support wheel 92 is rotatably connected to the inside of the frame 91, a first motor 93 for driving the support wheel 92 to rotate is fixedly connected to one side of the frame 91, and a pressure sensor 95 is fixedly connected to the lower part of the frame 91.
[0024] Two fixing blocks 7 are welded on the frame 6 , and a slide groove 8 is fixedly connected to the upper portion of the fixing block 7 . The lower portion of the pressure sensor 95 is arranged inside the slide groove 8 .
[0025] A second motor 11 is fixedly connected to the left side wall of the frame 6 , and a bidirectional lead screw 10 is fixedly connected to the output shaft of the second motor 11 .
[0026] The rear side of the frame 91 is fixedly connected to a limit plate 94 , and the bidirectional lead screw 10 is transmission-connected to the limit plate 94 via threads.
[0027] Circular baffles 96 are fixedly connected to the left and right sides of the support wheel 92 , respectively, and a receiving groove is provided between the two circular baffles 96 .
[0028] The surface of the support wheel 92 is provided with a rough layer composed of a plurality of lines, the upper part of the support wheel 92 is provided with a luggage case 1 to be detected, and the left side of the frame 6 is provided with a plurality of switches 5 .
[0029] Design of the vertical plate 4 and the socket 3: By arranging the vertical plate 4 on the frame 6 and opening a plurality of groups of sockets 3, and inserting the limit rods 2 therein, this design provides a flexible positioning mechanism for suitcases 1 of different sizes. The bent portion of the limit rod 2 ensures the stable fixation of the suitcase 1, improves the versatility and accuracy of the detection, and solves the disadvantage of poor adaptability of the traditional fixing device.
[0030] The pressure detection device 9 is integrated with the chute 8: the pressure detection device 9 not only has a built-in frame 91, a support wheel 92 and a first motor 93, but also has a pressure sensor 95 at the bottom thereof limited by the chute 8. This innovative design improves the sensitivity and accuracy of the detection. The structure of the chute 8 enables the sensor to be adjusted according to the weight distribution of the suitcase 1, effectively solving the problem of misjudgment caused by changes in the center of gravity in static detection.
[0031] The second motor 11 and the bidirectional screw 10 drive system: The second motor 11 is fixed on the left side wall of the frame 6 and connected to the limit plate 94 through the bidirectional screw 10. This design realizes the automatic entry and exit and position adjustment function of the luggage box 1, greatly improves the detection efficiency, and reduces the labor intensity. The use of the bidirectional screw 10 reflects the ingenious idea of achieving precise positioning in a limited space and improves the automation level of the overall device.
[0032] Combination of the support wheel 92 and the circular baffle 96: The rough layer design on the surface of the support wheel 92 increases the friction with the bottom of the suitcase 1, effectively avoiding slipping during the detection process, while the accommodating grooves formed by the circular baffles 96 on both sides provide additional stable support for the wheels of the suitcase 1, ensuring that the dynamic balance assessment during the detection process is more accurate, and solving the technical bottleneck of the traditional smooth surface support wheel 92 being easy to slip.
[0033] Configuration of control switch 5: Several control switches 5 are arranged on the left side of the rack 6, providing the operator with an intuitive and convenient control interface, simplifying the operation process of the equipment, and improving the usability and user-friendliness of the system. Although this design seems simple, in automation equipment, an easy-to-operate control system is crucial to improving overall work efficiency.
[0034] Working principle: When in use, hang the pull rod of the suitcase 1 on the limit rod 2, and select the sockets 3 of different heights for the limit rod 2 as needed. Place the wheels of the suitcase 1 above the support wheels 92. If the size is not suitable, turn on the switch 5 of the second motor 11 to adjust the distance between the two support wheels 92. After adjustment, turn on the power of the first motor 93. The first motor 93 can drive the support wheels 92 to rotate, thereby simulating the shape of the suitcase 1 in actual use. The frame 91 can press down the pressure sensor 95, so that the two pressure sensors 95 output different currents. By connecting the ammeter to observe the current values of the two sensors, it is possible to compare whether the two sides of the suitcase 1 are balanced.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
