Description

Technical Field

[0001] The utility model relates to the technical field of gravity sensing devices, and in particular to a gravity sensing device used at the entrance and exit of a gate. Background Art

[0002] In outdoor parking lots, it is common to see large and small cars parked close together. Although there are significant differences in the load capacity of these vehicles, the parking lot's charging policy is often unified and does not distinguish between the load capacity of the vehicles. This equal charging model may feel unfair to users of small vehicles.

[0003] For this reason, some parking lots have implemented a plan to weigh vehicles to differentiate the billing prices. Since the vehicle's own weight is large, usually measured in tons, conventional weighing devices are difficult to meet the requirements of car weighing. The most common vehicle weighing device is a floor scale. Floor scales come in different sizes. For example, in immigration management, a large floor scale weighing platform is used to weigh vehicles entering and leaving the country to monitor the weight of the goods. However, this type of floor scale occupies a large area and is costly, and is obviously not suitable for parking lots.

[0004] On the other hand, if a weighing device is installed for each parking space, the cost is also very high, which is obviously not appropriate. Therefore, the appropriate approach is to weigh the vehicles at the entrance and exit of the parking lot before releasing them. However, some vehicles will follow other vehicles to avoid weighing and charging. For this reason, isolation settings need to be provided to ensure that each vehicle can enter the weighing area and pass through the gate separately.

[0005] For example, the patent document with announcement number CN212871431U provides a floor scale that is easy to maintain, including a ground body, both sides of the top of the ground body are fixedly connected with inclined plates, the top of the ground body is fixedly connected with a support spring, the top of the support spring is fixedly connected with the floor scale body, and the center of the bottom of the floor scale body is fixedly connected with a weighing sensor. This type of floor scale is suitable for vehicle management in small places. Due to the use of a spring structure, the floor scale itself will produce a sinking deformation during weighing to complete the trigger signal of the weighing sensor, but it also creates some potential problems. Specifically, there is a height difference between the sinking part and the inclined plate, which may cause the vehicle to feel frustrated during movement, especially for vehicles with a low chassis, which may cause inconvenience and even affect the overall experience of the owner. In addition, this height difference may also make it difficult for the tire to drive out of the sinking part. If the driver steps on the accelerator to overcome this obstacle, the risk of an accident may increase.

[0006] Therefore, it is urgent to propose a gravity sensing device applied to the entrance and exit of the gate to solve the above technical problems. Summary of the invention

[0007] In view of the problems in the related technology, the utility model proposes a gravity sensing device applied to the entrance and exit of the gate, which has low cost, can prevent car following, and is safe and comfortable.

[0008] The utility model is achieved in this way:

[0009] A gravity sensing device used at a gate entrance and exit, which is arranged at a parking lot entrance and exit, wherein a gate and a camera are arranged at the parking lot entrance and exit, and the camera is used to identify the license plate number of the vehicle; the gravity sensing device is installed on the road at the parking lot entrance and exit; the camera is located in front of the gravity sensing device and faces the gravity sensing device;

[0010] The gravity sensing device comprises a base, a load-bearing plate, a weighing sensor and a lifting plate;

[0011] The base is provided with slope parts at both ends along the road direction; a sunken deformation part is provided between the two slope parts; the load-bearing plate is installed in the deformation part; the deformation part has a space for the load-bearing plate to move up and down in the vertical direction; the weighing sensor and a plurality of evenly distributed buffer springs are installed between the load-bearing plate and the bottom of the deformation part;

[0012] The lifting plate is provided at the slope portion away from the barrier gate; the gravity sensing device is also provided with a driving device; the output end of the driving device is hinged to one side of the lifting plate.

[0013] When the lifting plate is raised, it blocks vehicles from driving over the load-bearing plate; when the lifting plate is lowered, vehicles can pass over the load-bearing plate normally. After the lifting plate is set, the behavior of following vehicles to pass through the checkpoint can be avoided. By setting up a gravity sensor device to weigh the vehicle, and using a camera to capture the license plate number and the gate machine, different charges can be implemented for vehicles of different weights, and the implementation cost of this solution is low.

[0014] As a further optimization of the above scheme, it also includes two auxiliary guide plates; the auxiliary guide plates are arranged in the deformation part and located above the load-bearing plate; a rotating shaft is provided on one side of the auxiliary guide plate, and the two ends of the rotating shaft are respectively hinged to the base; the direction of the rotating shaft is perpendicular to the road direction, and the two rotating shafts are respectively close to the slope part.

[0015] When the load-bearing plate sinks under the action of the vehicle, a "cliff" with a height difference is formed between it and the highest position of the base, and the feedback generated affects the driving operation of the vehicle driver. One side of the auxiliary guide plate will sink with the load-bearing plate during the sinking process, and rotate around the axis to form an inclined surface. The effect presented is that the two ends of the inclined surface connect the highest position of the load-bearing plate and the base, effectively solving the "cliff" problem.

[0016] As a further optimization of the above solution, the upper side of the load-bearing plate is provided with an adapting platform formed by sinking; there are two adapting platforms, which are respectively arranged at the two end edges of the load-bearing plate; the adapting platform and the auxiliary guide plate are adapted in size.

[0017] As a further optimization of the above solution, the cross-section of the auxiliary guide plate is an airfoil; the two ends of the airfoil are a starting end and an end end respectively; the airfoil gradually tapers from the starting end to the end; and the rotating shaft vertically passes through the starting end.

[0018] The auxiliary guide plate is a wing-shaped structure, which is convenient for connecting with the various planes of the base, so that the overall upper surface of the gravity sensing device presents a smooth transition, providing the driver with a better driving experience and smoother driving feedback.

[0019] As a further optimization of the above solution, a first concave limiting groove is provided on the surface of the slope portion; the first limiting groove and the lifting plate are adapted to each other.

[0020] As a further optimization of the above scheme, a plurality of second limit grooves are provided at the bottom of the deformation part; a plurality of third limit grooves are provided on the lower side of the load-bearing plate; and one of the buffer springs corresponds one by one to one of the second limit grooves and one of the third limit grooves.

[0021] As a further optimization of the above scheme, the cross-section of the lifting plate is an airfoil; the two ends of the airfoil are respectively a starting end and an end end; the airfoil gradually tapers from the starting end to the end end; and one end of the lifting plate hinged to the driving device is located at the starting end.

[0022] The lifting plate has an airfoil structure, which is beneficial to reducing the load of the driving device; the center of gravity of the lifting plate is close to the starting end, and it is easier to be driven to lift or lower by the driving device.

[0023] As a further optimization of the above solution, the camera is an infrared camera.

[0024] Infrared cameras are able to work in complete darkness and can capture not only visible light but also infrared radiation, making it easier to identify vehicles at night.

[0025] As a further optimization of the above solution, the upper surface of the gravity sensing device is provided with a plurality of evenly distributed anti-slip grooves.

[0026] As a further optimization of the above solution, when the lifting plate is lifted, the angle of the lifting plate relative to the road is 30° to 60°.

[0027] The beneficial effects are as follows:

[0028] The utility model provides a gravity sensing device applied to the entrance and exit of the gate. After the lifting plate is set, the behavior of following the vehicle and breaking the card can be avoided. By setting the gravity sensing device to weigh the vehicle, and cooperating with the camera to shoot the license plate number and the gate, a differentiated charging mechanism based on the vehicle weight is realized. Compared with the existing technology, this solution has a lower implementation cost. In addition, an auxiliary guide plate is specially designed in the device to further enhance the driving experience and stability of the vehicle when the vehicle passes. The setting of the auxiliary guide plate optimizes the transition of the vehicle when passing through the gravity sensing area, reduces the inconvenience to the owner and the vehicle, and improves the overall comfort of use.

[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] like Figures 1 to 5 As shown, this embodiment provides a gravity sensing device 3 applied to the entrance and exit of the gate 1, which is arranged at the entrance and exit of the parking lot. The gate 1 and the camera 2 are arranged at the entrance and exit of the parking lot. The camera 2 is used to identify the license plate number of the vehicle. In this embodiment, the camera 2 is an infrared camera. The infrared camera can work in a completely dark environment, and can not only capture visible light, but also infrared radiation, so as to facilitate the identification of vehicles at night.

[0046] The gravity sensing device 3 is installed on the road at the entrance and exit of the parking lot; the camera 2 is located in front of the gravity sensing device 3 and faces the gravity sensing device 3;

[0047] The gravity sensing device 3 includes a base 31, a load-bearing plate 32, a weighing sensor 33 and a lifting plate 34;

[0048] In this embodiment, the upper side of the load-bearing plate 32 is provided with an adapting platform 321 formed by sinking; there are two adapting platforms 321, which are respectively provided at the two end edges of the load-bearing plate 32;

[0049] The base 31 is provided with slope parts 311 at both ends along the road direction; a sunken deformation part 312 is provided between the two slope parts 311; the load-bearing plate 32 is installed in the deformation part 312; the deformation part 312 has a space for the load-bearing plate 32 to move up and down in the vertical direction; a weighing sensor 33 and a plurality of evenly distributed buffer springs 35 are installed between the load-bearing plate 32 and the bottom of the deformation part 312;

[0050] In this embodiment, a plurality of second limiting grooves 314 are provided at the bottom of the deformation portion 312; a plurality of third limiting grooves 322 are provided on the lower side of the load-bearing plate 32; and a buffer spring 35 corresponds to a second limiting groove 314 and a third limiting groove 322 one by one.

[0051] A lifting plate 34 is provided at the slope portion 311 away from the gate machine 1 . In this embodiment, a concave first limiting groove 313 is provided on the surface of the slope portion 311 . The first limiting groove 313 and the lifting plate 34 are adapted to each other.

[0052] The gravity sensing device 3 is also provided with a driving device, the output end of which is hinged to one side of the lifting plate 34. In this embodiment, the driving device is a motor.

[0053] In this embodiment, two auxiliary guide plates 36 are further included; the cross section of the auxiliary guide plate 36 is an airfoil; the two ends of the airfoil are a starting end 361 and an end 362 respectively; the airfoil gradually tapers from the starting end 361 to the end 362;

[0054] The auxiliary guide plate 36 is arranged in the deformation part 312 and is located above the load-bearing plate 32; a rotating shaft 363 is arranged on one side of the auxiliary guide plate 36, and both ends of the rotating shaft 363 are respectively hinged to the base 31; the direction of the rotating shaft 363 is perpendicular to the road direction, and the two rotating shafts 363 are respectively close to the slope part 311; specifically, the rotating shaft 363 vertically passes through the starting end 361. The size of the adapting platform 321 and the auxiliary guide plate 36 is adapted.

[0055] After the load-bearing plate 32 sinks under the action of the vehicle, a "cliff" with a height difference is formed between the load-bearing plate 32 and the highest position of the base 31, and the feedback generated affects the driving operation of the vehicle driver. One side of the auxiliary guide plate 36 will sink along with the load-bearing plate 32 during the sinking process, and rotate around the rotation axis 363 to form an inclined surface, and the effect presented is that the two ends of the inclined surface connect the highest positions of the load-bearing plate 32 and the base 31, effectively solving the "cliff" problem.

[0056] The auxiliary guide plate 36 is a wing-shaped structure, which is convenient for connecting with various planes where the base 31 is located, so that the upper surface of the gravity sensing device 3 as a whole presents a smooth transition, providing the driver with a better driving experience and smoother driving feedback.

[0057] When the lifting plate 34 is raised, the angle of the lifting plate 34 relative to the road is 50 degrees, blocking vehicles from driving above the load-bearing plate 32; when the lifting plate 34 is lowered, vehicles can pass normally above the load-bearing plate 32. After the lifting plate 34 is set, the behavior of following vehicles to pass through the card can be avoided.

[0058] A more specific implementation is that when a vehicle is about to enter the parking lot, it first drives into the load-bearing plate 32 of the gravity sensing device 3, and at this time the lifting plate 34 is lifted to prevent the rear vehicle from following the vehicle; during weighing, the load-bearing plate 32 sinks and presses down under the action of the vehicle, and slowly deforms under the reaction force of the buffer spring until it contacts the weighing sensor 33, triggering a signal to complete the weight measurement; the final weighing result is added with the pre-calculated elastic force of multiple springs; while weighing, the vehicle can be photographed, the license plate number can be extracted and bound, so as to complete the differentiated charging of vehicles of specific weight; after weighing and photographing, the vehicle can pass through the barrier gate 1.

[0059] By setting up a gravity sensing device 3 to weigh the vehicle and cooperating with the camera 2 to shoot the license plate number and the gate 1, different charges can be implemented for vehicles of different weights, and the implementation cost of this solution is low.

[0060] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
