[0028] Please see Figures 1 to 4 This utility model provides a drop test bench with data uploading function, including a base 10, a lifting platform 20 disposed on the upper end of the base 10, a fixing frame 30 disposed on one side of the base 10, a top plate 40 disposed on the upper end of the fixing frame 30, a lifting mechanism penetrating the lifting platform 20, the fixing frame 30 and the top plate 40, a drop support 60 disposed on the edge of the upper end of the lifting platform 20, an automatic clamp 70 connected to the drop support 60, and a release mechanism 80 disposed on the side of the lifting platform 20 near the automatic clamp 70. A data acquisition device 90 is provided on the side of the lifting platform 20 near the automatic clamp 70, and a display 100 connected to the data acquisition device 90 is provided on one side of the lifting platform 20.

[0029] The aforementioned drop test bench with data uploading function allows the data acquisition device 90 to read the height of the lifting platform 20, thereby obtaining the drop height of the product under test and transmitting the drop height to the cloud. At the same time, the real-time drop height value is displayed on the display 100, realizing automatic recording of experimental data and reducing labor intensity.

[0030] In one embodiment of this utility model, please refer to Figure 3The lifting mechanism includes a chain located at the motor, passing through the lifting platform, the fixed frame, and the top plate, and sprockets located in the lifting platform, the fixed frame, and the top plate, all of which cooperate with the chain.

[0031] In one embodiment of this utility model, a base plate 11 is further provided at the lower end of the base 10. The base 10 serves as the basic support for the entire test bench, providing a stable platform. The base plate 11 at its lower end further enhances the stability and ground adaptability of the test bench, effectively preventing swaying or displacement during operation. The lifting platform 20 is located at the upper end of the base 10 and achieves vertical lifting movement via a motor-driven chain 50 and sprocket, thereby raising the drop test bracket 60 and the product to be tested on it to a predetermined height, providing the necessary conditions for the drop test.

[0032] In one embodiment of this utility model, wear-resistant steel plates 31 are provided at both corners of the fixed frame 30 near the lifting platform 20. Specifically, the fixed frame 30 is located on one side of the base 10, and its top plate 40 cooperates with the lifting platform 20 to jointly support the operation of the chain 50, ensuring the stability and accuracy of the lifting platform 20 during the lifting process. The wear-resistant steel plates 31 provided at the two corners of the fixed frame 30 near the lifting platform 20 effectively reduce the friction and wear between the lifting platform 20 and the fixed frame 30 during frequent lifting, improving the service life and reliability of the equipment. At the same time, a limiting block 32 is provided on the upper side of the fixed frame 30 near the lifting platform, which can precisely limit the rising position of the lifting platform 20, preventing the lifting platform 20 from rising excessively and causing equipment damage and safety accidents. The chain 50 passes through the lifting platform 20, the fixed frame 30, and the top plate 40, and realizes the transmission of power and the stable lifting of the lifting platform by cooperating with the sprockets in each component. A motor 52 is fixedly installed inside the base 10 and connected to the corresponding sprocket, serving as the power source for the lifting movement of the lifting platform 20. Precise control of the motor ensures the accuracy and repeatability of the drop height. In practice, mounting slots can be provided at the locations where the chain 50 is installed on the lifting platform 20, the fixed frame 30, and the top plate 40 to further improve the operational stability of the chain 50.

[0033] In one embodiment of this utility model, please refer to Figure 5The data acquisition device 90 includes an ultrasonic sensor and a communication chip. Specifically, the ultrasonic sensor is used to accurately measure the drop height of the product under test. It has the advantages of high precision and non-contact measurement, and can acquire drop height information in real time and accurately. The communication chip is responsible for transmitting the acquired data to the cloud, realizing remote storage and management of the data, allowing users to view and analyze the test data at any time. Meanwhile, a display connected to the data acquisition device is also provided on one side of the lifting platform, which can intuitively display the real-time acquired drop height value, allowing on-site operators to monitor the test process and data in real time. It should be noted that the ultrasonic sensor is one of the core components of the data acquisition device, used to measure the drop height of the product under test. It utilizes the principle of ultrasonic wave reflection, emitting ultrasonic signals downwards and receiving ultrasonic signals reflected back from the surface of the base plate. By measuring the propagation time of the ultrasonic waves, the distance between the ultrasonic sensor on the lifting platform and the base plate is calculated, thus obtaining the drop height value. The ultrasonic sensor has advantages such as high precision, high reliability, and non-contact measurement, and can acquire drop height information in real time and accurately, with measurement accuracy down to the millimeter level. The communication chip is responsible for transmitting the data acquired by the ultrasonic sensor to the cloud. It employs wireless communication technologies (such as Wi-Fi, Bluetooth, 4G, or 5G) to package data into a specific format and send it to a pre-configured cloud server. The communication chip boasts advantages such as low power consumption, high stability, and fast data transmission speed, ensuring timely and accurate data upload. During the test bench's operation, the communication chip maintains a real-time connection with the cloud server. When the ultrasonic sensor acquires new data, it immediately sends the data to the cloud, allowing users to view and analyze test data from anywhere with a network connection. The data acquisition device also includes a microprocessor and a storage chip. The microprocessor processes and analyzes the data acquired by the ultrasonic sensor, performing operations such as filtering, amplification, and calculations to improve data accuracy and reliability. The storage chip temporarily stores the acquired data, uploading it to the cloud when the communication chip maintains a normal connection with the cloud server. Simultaneously, the data acquisition device can also perform local data backup to prevent data loss. A display connected to the data acquisition device displays the drop height value of the product under test in real time. It uses a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display, capable of clearly displaying numbers and characters. The monitor has a simple and clear interface design. In addition to displaying the drop height value, it can also display information such as the number of tests, test time, and equipment status, making it convenient for operators to understand the test situation in real time.

[0034] In one embodiment of this utility model, during a drop test, the product under test needs to be measured at different placement angles to simulate the drop conditions that may occur during logistics handling. The drop bracket 60 and the release plate 82 work together to maintain the product under test at different placement angles. The drop bracket 60 includes a first vertical rod 61 connected to the lifting platform 20, a horizontal rod 62 connected to the first vertical rod 61, and a second vertical rod 63 connected to the horizontal rod 62. The automatic clamp 70 is located at the lower end of the second vertical rod 63. Specifically, the drop bracket 63 is located on the upper edge of the lifting platform 20, and its structural design can meet the fixing requirements of products under test of different sizes and shapes. The automatic clamp 70 is located at the lower end of the second vertical rod, which can firmly clamp the product under test, ensuring that the product will not fall off or shift before the drop test, thus ensuring the accuracy and reliability of the test results.

[0035] In one embodiment of this utility model, the first vertical rod 61 and the second vertical rod 63 are connected to the horizontal rod 62 via a movable connector 64. Specifically, in this embodiment, the movable connector 60 consists of two vertically arranged internally threaded tubes. The first vertical rod 61 and the second vertical rod 63 are both circular rods, and the outer diameters of the first vertical rod 61 and the second vertical rod 63 are substantially the same as the inner diameter of the movable connector. This allows the first vertical rod 61 and the second vertical rod 63 to be fixed within the movable connector 64, and also allows for adjustment of the connection position, thereby adjusting the position of the automatic clamp 70.

[0036] In one embodiment of this utility model, a guide rod 21 is further provided at the upper end of the lifting platform 20, and the upper end of the guide rod 21 penetrates the top plate 40. This makes the lifting platform 20 more stable when rising and falling.

[0037] In one embodiment of the present invention, the release mechanism 80 includes a release motor 81, a release plate 82 and a flat key 83, wherein the release plate 82 is connected to the output shaft of the release motor 81 via the flat key 83.

[0038] It should be noted that the automatic clamp 70 can use either mechanical or pneumatic clamping to quickly and securely hold the product to be tested. Mechanically clamped automatic clamps typically consist of clamping arms, clamping bolts, and springs. Rotating the clamping bolts causes the clamping arms to retract inward, thus clamping the product. Pneumatically clamped automatic clamps utilize compressed air as a power source. The extension and retraction of a cylinder drives the clamping arms to clamp and release the product. The clamping arms of the automatic clamp 70 are covered with soft materials such as rubber or polyurethane, which increases friction with the product, preventing it from slipping before the drop test. The synchronized release of the automatic clamp 70 and the release plate 82 ensures the product falls from the set angle.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
