Description

Technical Field

[0001] This utility model relates to the field of curb toll collection machines, and in particular to a lifting swing arm mechanism and a curb toll collection machine. Background Technology

[0002] A curb-mounted parking payment machine is a smart parking payment machine installed on the curb, flexibly supporting installation on the left or right side of a parking space. It uses a starlight-level high-definition low-light color camera to detect vehicles and recognize license plates in low light conditions. Powered by a battery or external AC power, it features wireless communication transmission and radar multi-mode detection, thus replacing manual payment and possessing broad market prospects. For example, Chinese utility model patent CN220868053U discloses a track-mounted curb lock, directly installed on the curb of a side parking space. It includes a track, a control unit, and a swing arm mechanism installed within the track. One end of the swing arm mechanism is rotatably connected to the control unit, and under the control unit's action, the other end rotates 90° around the connection point, achieving a perpendicular setting to the track. This locks the car between its front and rear wheels, and the control unit recognizes the license plate and automatically calculates and charges the fee.

[0003] These types of curb toll collection machines are suitable for most vehicles. However, for some vehicles with high chassis or some drivers who intend to evade tolls, the height of the barrier arm housing of this type of curb toll collection machine is not enough to effectively block the vehicle. Drivers can drive directly over the barrier arm housing, which not only results in the loss of parking fees but also damages the barrier arm housing, leading to high maintenance costs and poor market response. Therefore, it is necessary to improve the structure of the existing curb toll collection machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lifting swing arm mechanism and a curb toll machine. The effective blocking height of the swing arm mechanism is adjustable, making it suitable for vehicles with chassis of different heights. This not only effectively reduces toll evasion but also lowers the risk of the swing arm mechanism being crushed and extends its service life.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A lifting swing arm mechanism includes a stop arm housing and an upper cover plate disposed on the top of the stop arm housing. The stop arm housing is provided with a first drive mechanism. The output end of the first drive mechanism is connected to the upper cover plate by a transmission mechanism and is adapted to drive the upper cover plate to perform lifting and lowering movements through the transmission mechanism.

[0007] Furthermore, the first driving mechanism is a horizontally arranged linear driving mechanism, and the transmission mechanism includes scissor fork assemblies symmetrically arranged on both sides of the stop arm housing. One bottom end of the scissor fork assembly is hinged to the stop arm housing, and the other end is movably connected to the stop arm housing in the horizontal direction and hinged to the output end of the linear driving mechanism. The upper cover plate has downwardly extending bent portions on both sides. One top end of the scissor fork assembly is hinged to the bent portion, and the other end is movably connected to the bent portion in the horizontal direction.

[0008] Furthermore, a base assembly is fixedly provided inside the stop arm housing. The bottom and side surfaces of the base assembly are respectively attached to the stop arm housing. Corresponding strip grooves are horizontally provided on the stop arm housing and the base assembly. One end of the bottom of the scissor fork assembly passes through the stop arm housing and is hinged to the base assembly. The other end is hinged to a pin that passes through the two strip grooves. The other end of the pin is fixedly connected to the output end of the linear drive mechanism.

[0009] Furthermore, the bottom of the base assembly is provided with multiple through slots.

[0010] Furthermore, the linear drive mechanism is an electric push rod, a hydraulic push rod, or an electric lead screw assembly.

[0011] Furthermore, the electric actuator is a non-self-locking type.

[0012] Furthermore, the bent portion has multiple through holes evenly distributed on it.

[0013] Furthermore, a buffer plate is fixedly provided on the top of the upper cover plate.

[0014] A curb toll collection machine includes a housing assembly with an opening on the side. One end of the housing assembly is provided with a control unit, and the other end is rotatably mounted with a swing arm mechanism as described above. Above the swing arm mechanism is a second drive mechanism mounted on the housing assembly. The second drive mechanism is electrically connected to the control unit and is adapted to drive the swing arm mechanism to rotate along a horizontal plane.

[0015] Furthermore, a spike is provided on the top side of the stop arm housing away from the control unit.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] (1) The present invention uses a first drive mechanism to drive the upper cover plate to move up and down relative to the arm housing through a transmission mechanism, thereby realizing the effective adjustment of the blocking height of the swing arm mechanism, and thus applicable to vehicles with different chassis heights. This not only effectively reduces the occurrence of toll evasion, but also reduces the risk of the swing arm mechanism being crushed and extends its service life.

[0018] (2) This utility model adopts a horizontally set linear drive mechanism to realize the drive in a narrow space. It uses a scissor fork assembly as a transmission mechanism. The bottom end of the scissor fork assembly is pulled horizontally by the linear drive mechanism to realize the lifting and lowering of the top cover plate. The structure is simple and the height adjustment range is large.

[0019] (3) This utility model improves the overall structural strength by adding a base component as a support.

[0020] (4) This utility model avoids water accumulation inside when used in rainy weather by opening a through groove at the bottom of the base assembly as a water outlet.

[0021] (5) The linear drive mechanism of this utility model can take many forms, and customers can choose freely according to their budget and usage scenarios to meet different usage needs.

[0022] (6) The electric push rod used in this utility model is a non-self-locking structure. When the swing arm mechanism is subjected to downward pressure, such as when it is run over by a car, the electric push rod will be stretched at the same time, and it is not easy to bend or deform and fail.

[0023] (7) This utility model reduces its own weight and load by setting multiple through holes in the bending part.

[0024] (8) By setting a buffer plate on the upper cover, this utility model avoids hard contact between the upper cover and the vehicle chassis when the upper cover rises, thus avoiding scratching the vehicle and reducing contact noise, thereby improving the user experience of the car owner.

[0025] (9) The curb toll machine of this utility model adopts a swing arm mechanism with an effective blocking height that can be raised and lowered, thereby realizing the vehicle locking function of vehicles with different chassis heights, which is more versatile, reduces toll evasion, and reduces the risk of the swing arm mechanism being run over.

[0026] (10) This utility model is equipped with a spike, and the spike is located on the side away from the control unit, just near the wheel, which plays a good warning role and further reduces the phenomenon of customers maliciously evading payment. Attached Figure Description

Detailed Implementation

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] (Example 1)

[0036] like Figures 1 to 4 The curb toll machine shown includes a housing assembly 1 with an opening on the side. A control unit 2 is located at one end of the housing assembly, and a swing arm mechanism is rotatably mounted at the other end. A second drive mechanism 3 is mounted on the housing assembly above the swing arm mechanism. The second drive mechanism 3 is electrically connected to the control unit 3, and its output is drively connected to the swing arm mechanism. The control unit 3 identifies nearby parked vehicles and controls the second drive mechanism 3 to drive the swing arm mechanism to rotate horizontally, causing the swing arm mechanism to extend or retract from the housing assembly, thus locking the vehicle by blocking the wheels. In practice, the control unit and the swing arm mechanism can also be mounted on the same end, with other structural elements adjusted accordingly.

[0037] Specifically, the connection and transmission structure of the second drive mechanism 3 and the swing arm mechanism are the same as those in Chinese Utility Model Application No. 2024202888350, and will not be repeated here. Only its basic structure is briefly described. The housing assembly 1 contains a connecting assembly 4, which includes a fixedly connected rotating part 4-1 and a fixed plate 4-2. A rotating pin 4-3, which is longitudinally mounted and limited between the top and bottom of the housing assembly 1, is provided on the rotating part 4-1. The swing arm mechanism contains a flexible connecting part, which consists of a connected steel cable connecting part and a spring connecting part. The other end of the flexible connecting part is connected to the fixed plate 4-2. The second drive mechanism 3 is an electric push rod whose main body is rotatably connected to the inner wall of the housing assembly 1. The push rod end of the electric push rod is rotatably connected to the rotating part 4-1. Through the extension and retraction of the electric push rod, the rotating part 4-1 is driven to rotate, thereby realizing the rotation of the flexibly connected swing arm mechanism.

[0038] The swing arm mechanism includes a stop arm housing 5 and an upper cover plate 6 located on top of the stop arm housing 5. A first drive mechanism 7 is provided inside the stop arm housing 5. A transmission mechanism 8 is connected between the output end of the first drive mechanism 7 and the upper cover plate 6 and is adapted to drive the upper cover plate 6 to perform lifting and lowering movements through the transmission mechanism 8, thereby realizing a lifting swing arm mechanism. When the swing arm mechanism extends out of the housing assembly 1, the upper cover plate 6 can be appropriately raised according to the vehicle chassis height to achieve a more suitable effective blocking height.

[0039] The first drive mechanism 7 is a horizontally positioned linear drive mechanism, which can be an electric push rod, a hydraulic push rod, or an electric lead screw assembly. Customers can freely choose according to their budget and usage scenario to meet different needs. This embodiment uses a non-self-locking electric push rod. When the swing arm mechanism is subjected to downward pressure, such as being run over by a vehicle, the electric push rod will be stretched simultaneously, making it less prone to bending and deformation leading to failure. The linear drive mechanism can also be installed at a certain angle, as long as it can pull the transmission mechanism.

[0040] The transmission mechanism 8 consists of scissor fork assemblies symmetrically arranged on both sides of the arm housing 5. A base assembly 9 is fixedly installed inside the arm housing 5, with its bottom and sides fitting against the arm housing 5 for better support and reinforcement, thus improving the overall structural stability. Corresponding horizontal slots 10 are provided on the arm housing 5 and the base assembly 9. One end of the bottom of the scissor fork assembly passes through the arm housing 5 and is hinged to the base assembly 9; the other end is hinged to a pin passing through both slots 10, with the other end of the pin fixedly connected to the output end of the electric push rod. The upper cover plate 6 has downwardly extending bent portions 6-1 on both sides, with multiple through holes evenly distributed on the bent portions 6-1 to reduce weight and load. One top end of the scissor fork assembly is hinged to the bent portion 6-1, and the other end is movably connected to the bent portion in a horizontal direction. The upper cover plate 6 is raised and lowered by pulling the bottom end of the scissor fork assembly using an electric push rod. This design is simple and has lower manufacturing costs.

[0041] A movable wheel 12 is provided between the end of the base assembly 9 near the control unit and the arm housing 5, thereby making the swing arm mechanism rotate more smoothly. Considering the risk of water ingress into the inner wall of the swing arm mechanism in rainy weather, this embodiment has multiple through grooves 9-1 at the bottom of the base assembly 9 for drainage. The drained water is then discharged from the notch at the movable wheel to avoid internal water accumulation and affecting normal use.

[0042] A buffer plate 13 is fixedly installed on the top of the upper cover plate 6 to prevent the upper cover plate 6 from making hard contact with the vehicle chassis when it rises, thereby avoiding scratches to the vehicle, reducing contact noise, and improving the user experience for car owners.

[0043] In addition, a spike 14 is provided on the top of the guard arm housing 5 on the side away from the control unit 2, which is located near the wheel, serving as a good warning and further reducing the phenomenon of customers maliciously evading tolls.

[0044] This utility model uses a first drive mechanism 7 to drive the upper cover plate 6 to move up and down relative to the stop arm housing 5 via a transmission mechanism 8, thereby realizing the effective adjustment of the blocking height of the swing arm mechanism. This makes it suitable for vehicles with chassis of different heights, effectively reducing toll evasion, lowering the risk of the swing arm mechanism being crushed, and extending its service life.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
