[0002] The lack of parking is a consequence of a city's social, economic, and transportation development. It severely impacts people's convenience and well-being, and poses a significant challenge to orderly and safe urban management. The advent of multi-story parking garages has effectively addressed this parking challenge.

[0003] A multi-story parking garage is a mechanical system designed to maximize the storage and retrieval of vehicles. Compared to underground garages, multi-story parking garages offer more effective protection for both personal and vehicle safety. The electronically controlled system will not operate if a person is inside the garage or a vehicle is parked in an unauthorized area. Therefore, multi-story parking garages offer a complete separation of personnel and vehicles. Multi-story parking garages consist of multiple movable entry platforms, each with a designed load capacity. However, the weight of vehicles of different models or uses generally varies. In particular, the rapid development of new energy vehicles in recent years, equipped with larger batteries and integrating more features, has led to an increase in vehicle weight. If a vehicle exceeding the design load capacity of an entry platform enters the platform, it poses a safety hazard, endangering the driver's safety and even causing irreversible structural damage to the multi-story parking garage.

[0027] Please refer to Figure 1-Figure 3 , a weighing device 100 according to an embodiment is installed on the ground 200 of a garage entrance. The garage entrance specifically refers to the entrance of a three-dimensional parking garage. After a vehicle enters the garage entrance, it arrives at a lifting platform, which is then used to move the vehicle to an empty parking space.

[0028] Exemplarily, the weighing device 100 includes a weighing frame 10, which is used to be installed on the ground 200 at the entrance of the garage, and the weighing frame 10 has a weighing plate 11 away from the ground 200; a weighing sensor 20, and a plurality of weighing sensors 20 are provided. The plurality of weighing sensors 20 are arranged in a rectangular shape in the weighing frame 10, and the weighing sensors 20 are all abutted against the weighing plate 11; and a prompt alarm system 30, which is electrically connected to the weighing sensor 20.

[0029] The load cell 20 is a device that converts mass signals into measurable electrical output signals. Once a vehicle is moved onto the load cell 20, its weight is directly measured, enabling unattended dynamic automatic weighing and automatically displaying the weighing results.

[0030] The warning alarm system 30 comprises at least a controller, a warning alarm, and a display instrument. The load cell 20, warning alarm, and display instrument are each electrically connected to the controller. The vehicle weight, as measured by the load cell 20, is output to the controller and display instrument, respectively. The controller compares the vehicle weight with the maximum load capacity of the parking garage. If the vehicle weight exceeds the maximum load capacity, it sends an alarm to the warning alarm. Simultaneously, the vehicle weight, comparison results, and other information are displayed on the display instrument for easy viewing by the user.

[0031] Optionally, the prompt alarm may be, but is not limited to, a sound alarm, a light alarm, an audible and visual alarm, or the like.

[0032] The implementation of the embodiment of the present utility model will have the following beneficial effects: the weighing device 100 of this scheme is installed on the ground 200 in front of the entrance to the garage. Vehicles that need to enter the multi-story garage will first pass through the weighing device 100. When the vehicle completely reaches the top of the weighing frame 10, the four wheels of the vehicle just correspond one-to-one with the four weighing sensors 20 distributed in a rectangular shape, so that the weighing sensors 20 can accurately measure the measured weight and transmit the weight data to the prompt alarm system 30. The prompt alarm system 30 compares the measured weight data with the maximum weight data that the multi-story garage can bear. When it is found that the weight of the vehicle exceeds the maximum load weight, an alarm prompt will be issued to remind the user to exit the vehicle in time and avoid driving into the multi-story garage. In this way, the potential personal injury safety hazards caused by overweight parking and the irreversible structural damage that may be caused to the multi-story garage can be effectively eliminated.

[0033] In one embodiment, the weighing frame 10 further includes a mounting base 12. The mounting base 12 and the weighing plate 11 are arranged side by side, spaced apart, along the height direction of the weighing frame 10. The mounting base 12 is located below the weighing plate 11 and has positioning holes for connection and fixation with positioning posts pre-set on the ground 200. Furthermore, the weighing frame 10 further includes a floating connection assembly 50. One end of the floating connection assembly 50 is connected to the weighing plate 11, and the other end of the floating connection assembly 50 is connected to the mounting base 12. The floating connection assembly 50 provides the weighing plate 11 and the mounting base 12 with the freedom to float closer or farther.

[0034] First, the mounting base 12 and the weighing plate 11 are spaced apart along the height direction of the weighing frame 10, and a mounting cavity can be formed between the two. The mounting cavity can be used to accommodate the weighing sensor 20, so that the weighing sensor 20 and the weighing frame 10 are assembled into one body, and the weighing frame 10 surrounds the outside of the weighing sensor 20 to protect the weighing sensor 20; secondly, the positioning holes preset on the mounting base 12 are connected with the positioning columns preset on the ground 200, so that the weighing device 100 is firmly and stably mounted on the ground as a whole. 200, to prevent the weighing device 100 from shifting and affecting the weighing operation when the vehicle moves onto the weighing device 100; furthermore, the weighing plate 11 is connected to the mounting base 12 by a floating connection assembly 50, and the weighing plate 11 can elastically float closer to or away from the mounting base 12, so that when the vehicle moves above the weighing plate 11, the weighing plate 11 will float downward by itself under the weight of the vehicle, so that the weighing sensor 20 can effectively abut the weighing plate 11 to accurately sense the vehicle weight, thereby improving the measurement accuracy.

[0035] It should be noted that the weighing plate 11 and the mounting base plate 12 are made of one of stainless steel plates, alloy steel plates, etc., and have sufficient structural strength and rigidity to avoid deformation due to excessive vehicle pressure, which affects the measurement accuracy of the vehicle weight.

[0036] Alternatively, in another embodiment, the weighing frame 10 further includes a mounting base 12, which is spaced apart and arranged side by side with the weighing plate 11 along the height direction of the weighing frame 10. The mounting base 12 is located below the weighing plate 11. A hanging ring is provided on the ground 200, and a hook is provided on the side of the mounting base 12 facing away from the weighing plate 11. The hook is clasped with the hanging ring. Similar to the positioning function and effect of the positioning post and the positioning hole in the above embodiment, this embodiment also allows the weighing device 100 to be securely mounted on the ground 200 by providing a hook and a hanging ring, and clasping the hook with the hanging ring.

[0037] It should be noted that the positioning posts and positioning holes as well as the hooks and hanging rings can be provided in more than one group. When two or more groups are provided at the same time, the installation strength and reliability of the weighing device 100 on the ground 200 can be further improved.

[0038] See also Figure 1 Based on the solution of directly installing the weighing device 100 on the surface of the ground 200, in a further embodiment, the ground 200 is recessed to form a foundation pit 210, the weighing frame 10 is installed in the foundation pit 210, and the upper surface of the weighing plate 11 is flush with the ground 200. The size and shape of the foundation pit 210 are adapted to the size and shape of the weighing frame 10. Therefore, after the weighing frame 10 is placed in the foundation pit 210, the circumferential side walls of the foundation pit 210 can clamp the weighing frame 10 and form a limiting effect on the weighing frame 10 in multiple directions, thereby further improving the installation stability of the weighing device 100. However, it should be noted that the upper surface of the weighing plate 11 at the top of the weighing frame 10 must be flush with the ground 200, so as to facilitate the movement of the wheels onto the weighing plate 11 and reduce the impact of the weighing device 100 from the vehicle.

[0039] The weighing frame 10 may protrude a certain height above the foundation pit 210 due to errors in the manufacturing dimensions of the weighing frame 10 or errors in the dimensional excavation of the foundation pit 210. In one embodiment, the weighing device 100 further includes a ramp 40. The foundation pit 210 is formed in a recessed manner in the ground 200. The weighing frame 10 is installed in the foundation pit 210. The weighing plate 11 is arranged at a preset height above the ground 200. The ramp 40 is connected between the edge of the weighing plate 11 and the ground 200. The inclined surface of the ramp 40 can smoothly connect the ground 200 at a lower position with the upper surface of the weighing plate 11 at a higher position, so that the wheels can move smoothly from the ground 200 to the weighing plate 11, reducing the impact on the weighing device 100.

[0040] See also Figure 3 In another optional embodiment, the weighing plate 11 is provided with a through hole 111 extending through the thickness of the weighing plate 11, and the weighing sensor 20 includes a measuring portion 21, which is disposed within the through hole 111. In the above embodiment, the measuring portion 21 abuts against the weighing plate 11, thereby indirectly measuring the weight of the vehicle through the weighing plate 11. When calculating the actual weight of the vehicle, it is often necessary to subtract the weight of the weighing plate 11 from the measured value, which is a complex process and results in large errors. In this embodiment, the measuring portion 21 extends from the through hole 111 and directly abuts against the vehicle wheel, thereby directly measuring the vehicle weight, simplifying the process steps for obtaining the measurement result, and improving the accuracy of vehicle weight measurement.

[0041] In one embodiment, the floating connection assembly 50 includes a bolt assembly and an elastic member. One end of the bolt assembly is fixedly connected to the weighing plate 11, while the other end of the bolt assembly is movably inserted into the mounting base 12. The elastic member is sleeved on the exterior of the bolt assembly, with opposite ends of the elastic member correspondingly abutting the weighing plate 11 and the mounting base 12. The bolt assembly rigidly connects the weighing plate 11 and the mounting base 12, improving the structural integrity of the weighing frame 10. The elastic member has excellent elasticity. When a vehicle moves onto the weighing plate 11, the vehicle's gravity forces the weighing plate 11 downward and floats relative to the mounting base 12. The elastic member contracts and deforms, providing a certain degree of support for the weighing plate 11 (primarily by ensuring the relative position of the weighing plate 11 and the mounting base 12, and supporting the vehicle load). This allows the measuring portion 21 to extend outside the through-hole 111, more effectively contacting the wheel and improving measurement accuracy.

[0042] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
