Description

Technical Field

[0001] This application belongs to the field of barrier gate technology, and in particular relates to a barrier arm device and a barrier gate system. Background Technology

[0002] A barrier gate, also known as a vehicle barrier, is a gate access control device used to restrict the movement of motor vehicles on roads. It is widely used in highway toll stations, parking systems, and other similar locations.

[0003] Common gate arm cross-sectional shapes currently on the market include: Figure 1 As shown, the width of a gate arm is typically greater than its thickness, resulting in a significant difference in mechanical strength in the two directions. The operating environment of the gate arm dictates that wind direction is usually parallel or nearly parallel to the ground, meaning the width of the gate arm experiences greater crosswind thrust. Furthermore, the mechanical strength of the gate arm is lower in the thickness direction than in the width direction. Therefore, existing gate arms will swing rapidly under strong winds, especially in turbulent wind conditions, making them prone to breakage in the thickness direction.

[0004] In conclusion, the current gate arm is not strong enough and is prone to breakage under strong winds. Utility Model Content

[0005] In view of this, embodiments of this application provide a gate arm device and a barrier gate system to solve the technical problems of insufficient strength of existing gate arms and easy breakage under strong winds.

[0006] In a first aspect, embodiments of this application provide a gate arm device, including: The main body of the barrier gate; A gate arm, one end of which is rotatably connected to the main body of the barrier gate, and the other end of which extends away from the main body of the barrier gate. The width of the gate arm is greater than the thickness of the gate arm. A damping element is detachably installed at the end of the gate arm away from the main body of the barrier gate. The damping element increases the weight of the end of the gate arm away from the main body of the barrier gate, thereby slowing down the response speed of the gate arm to the wind.

[0007] In some embodiments, the damping element includes a damping ring, which is sleeved on the end of the gate arm away from the gate body.

[0008] In some embodiments, the damping element further includes a spring damper, the middle portion of which is fixed to the damping ring, and the two ends of which are respectively located on both sides of the thickness direction of the gate arm.

[0009] In some embodiments, two spring dampers are provided, and the two spring dampers are distributed along the width direction of the gate arm.

[0010] In some embodiments, the damping element includes a spring damper, the middle portion of which is connected to the end of the gate arm.

[0011] In some embodiments, the damping element includes: An elastic rod is provided at the end of the gate arm away from the main body of the barrier gate, and the elastic rod extends along the length direction of the gate arm; A pendulum is located at the end of the elastic rod away from the gate arm.

[0012] In some embodiments, the spring damper includes: A housing, wherein a sliding groove is provided inside the housing; The counterweight is slidably installed in the groove. Each end of the counterweight is provided with a return spring. One end of the return spring is connected to the housing, and the other end of the return spring is connected to the counterweight.

[0013] In some embodiments, the damping element further includes at least one elastic rod damper, the elastic rod damper including an elastic rod and a pendulum, the elastic rod being connected to the damping ring, and the pendulum being connected to the end of the elastic rod away from the damping ring.

[0014] In some embodiments, the damping element further includes a damping cylinder and a damping fluid filled in the damping cylinder. The middle part of the damping cylinder is connected to the damping ring, and the two ends of the damping cylinder are respectively located on both sides in the thickness direction of the gate arm. The damping fluid moves in the damping cylinder to reduce the swing amplitude of the gate arm.

[0015] In some embodiments, two elastic rod dampers are provided, and the two elastic rod dampers are distributed along the width direction of the gate arm; or the two elastic rod dampers are distributed along the thickness direction of the gate arm.

[0016] In some embodiments, the ratio of the distance between the damping element and the main body of the barrier gate to the length of the gate arm is 0.7 to 0.9:1.

[0017] Secondly, embodiments of this application provide a barrier gate system, including: The gate arm device described in the first aspect; A sensing device is installed inside the barrier gate body. The sensing device is used to sense vehicles entering and / or leaving a preset position and generate a gate raising signal or gate lowering signal. An electronic control device is installed inside the barrier gate body to receive the raising or lowering signal of the barrier arm and control the barrier arm to raise or lower.

[0018] The gate arm device and barrier gate system provided in this application embodiment, without increasing the overall thickness of the gate arm, by setting a damping component at one end of the gate arm, when the gate arm is subjected to crosswinds, the damping component effectively increases the weight at the end of the gate arm, which can effectively reduce the swing speed and amplitude of the gate arm in a windy environment, so as to avoid the gate arm breaking due to large-amplitude shaking, thereby reducing metal fatigue of the gate arm and extending the service life of the gate arm.

Therefore, the phrases "in some embodiments," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiments, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0028] like Figure 1 As shown, Figure 1 The diagram shows a side view of the current mainstream gate arm 20 (a side view schematic diagram perpendicular to the length direction of the gate arm 20). The width of the gate arm 20 is significantly larger than its thickness, resulting in a significant difference in mechanical strength in these two directions. The operating environment of the vehicle brake dictates that wind direction is usually parallel or nearly parallel to the ground, and the force-bearing surface in the width direction is typically subject to greater crosswind thrust. Furthermore, the mechanical strength of the gate arm 20 is lowest in the thickness direction. Under strong winds and in turbulent wind conditions, the gate arm 20 is more prone to breakage in the thickness direction. Current solutions aim to increase the strength of the gate arm 20 by increasing its thickness; however, this solution significantly increases manufacturing costs and energy consumption, requiring a larger power system for daily raising and lowering of the gate arm 20.

[0029] Based on the above problems, the first aspect of this application provides a gate arm 20 device and a barrier gate system. Without increasing the overall thickness of the gate arm 20, by setting a damping element 30 at one end of the gate arm 20, when the gate arm 20 is subjected to crosswinds, the damping element 30 effectively increases the weight at the end of the gate arm 20, which can effectively reduce the swing speed and amplitude of the gate arm 20 in a windy environment, so as to avoid the gate arm 20 breaking due to large-scale shaking, thereby reducing metal fatigue of the gate arm 20 and extending the service life of the gate arm 20.

[0030] like Figure 2 and Figure 3 As shown, this application provides a gate arm 20 device, including a gate body 10, a gate arm 20, and a damping component 30; One end of the gate arm 20 is rotatably connected to the barrier gate body 10, and the other end of the gate arm 20 extends away from the barrier gate body 10. The width of the gate arm 20 is greater than the thickness of the gate arm 20. The damping element 30 is detachably installed at the end of the gate arm 20 away from the gate body 10. The damping element 30 increases the weight of the end of the gate arm 20 away from the gate body 10, thereby slowing down the response speed of the gate arm 20 to the wind.

[0031] The gate arm 20 device provided in this application embodiment, without increasing the overall thickness of the gate arm 20, provides a damping element 30 at one end of the gate arm 20. When the gate arm 20 is subjected to crosswinds, the damping element 30 effectively increases the weight at the end of the gate arm 20, which can effectively reduce the swing speed and amplitude of the gate arm 20 in a strong wind environment, so as to avoid the gate arm 20 breaking due to large-amplitude shaking, thereby reducing metal fatigue of the gate arm 20 and extending the service life of the gate arm 20.

[0032] In application, the damping element 30 is detachably installed at the end of the gate arm 20 away from the gate body 10. The detachable installation method includes fixing with screws, or connection methods such as snap-fit, plug-in, riveting, or magnetic connection. As long as the damping element 30 can be fixed to the end of the gate arm 20 away from the gate body 10, it is acceptable. This setup allows for selective use of the damping element 30 depending on the specific installation scenario of the gate arm 20. For example, when the gate arm 20 is installed in an indoor parking lot, the gate arm 20 itself may not be exposed to strong winds, so the damping element 30 is not needed to mitigate the effect of strong winds on the gate arm 20. However, if the gate arm 20 is installed outdoors in a place frequently exposed to strong winds, the damping element 30 can be installed on the gate arm 20 to help it withstand strong winds, increase the local weight of the gate arm 20, reduce the speed and amplitude of the gate arm 20's swing, and thus prevent the gate arm 20 from breaking.

[0033] In applications, such as Figure 2 and Figure 3 As shown, the gate arm 20 includes a fixed end 200 and a movable end 201. The fixed end 200 is rotatably connected to the gate body 10, and the movable end 201 extends away from the gate body 10. The movable end 201 is the end of the gate arm 20 that is raised or lowered. A damping element 30 is installed on the movable end 201. Because the fixed end 200 is connected to the gate body 10, the movable end 201 is usually suspended in the air. When subjected to crosswinds, it is prone to swaying. Therefore, installing the damping element 30 on the movable end 201 can effectively increase the weight of the movable end 201. When subjected to strong winds, it can reduce the overall response speed of the gate arm 20 to strong winds, that is, reduce the swing speed and amplitude, reduce metal fatigue of the gate arm 20, and make the gate arm 20 less prone to breakage, thereby extending the service life of the gate arm 20.

[0034] It should be noted that the length direction of the gate arm 20 is the X direction in the figure, the width direction of the gate arm 20 is the Y direction in the figure, and the thickness direction of the gate arm 20 is the Z direction in the figure. Typically, the crosswind direction encountered by the gate arm 20 is the Z direction. The above is for ease of understanding and to illustrate the technical solution of this application, and should not be construed as limiting the scope of protection of the embodiments of this application.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the damping component 30 includes a damping ring 31, which is sleeved on the end of the gate arm 20 away from the gate body 10. Under crosswind conditions, the gate arm 20 will swing in the direction of the crosswind, and the damping ring 31 will swing along with the gate arm 20. Since the damping ring 31 effectively increases the local weight of the gate arm 20 (the weight of the moving end), it slows down the response speed of the gate arm 20 to strong winds, reduces metal fatigue of the gate arm 20, and extends the service life of the gate arm 20.

[0036] In some embodiments, such as Figure 4 As shown, the damping component 30 also includes a spring damper 32. The middle part of the spring damper 32 is fixed to the damping ring 31, and the two ends of the spring damper 32 are located on both sides of the thickness direction of the gate arm 20. When the gate arm 20 is subjected to crosswinds, it will swing along the direction of the crosswinds, and the spring damper 32 swings along with the gate arm 20. By distributing the spring damper 32 in the thickness direction of the gate arm 20, it can counteract part of the effect of the crosswinds. Even if the swing frequency of the spring damper 32 and the gate arm 20 is not the same, it can reduce the swing amplitude of the gate arm 20. In addition, the weight of the spring damper 32 plus the damping ring 31 also makes the gate arm 20 more difficult to be blown away.

[0037] In some embodiments, such as Figures 4 to 6 As shown, the spring damper 32 includes a housing 321 and a counterweight 322; The housing 321 has a sliding groove 320 inside; The counterweight 322 is slidably installed in the slide groove 320. Return springs 323 are provided at both ends of the counterweight 322. One end of the return spring 323 is connected to the housing 321, and the other end is connected to the counterweight 322. When the gate arm 20 is subjected to crosswinds, it will swing. The spring damper 32 swings along with the gate arm 20. The counterweight 322 inside the spring damper 32, due to inertia, will experience a delayed movement, thus offsetting the swing amplitude of the gate arm 20. When the gate arm 20 resets, the counterweight 322 moves in the opposite direction under the action of the return spring 323, which can also partially or completely offset the swing speed of the gate arm 20. In a specific embodiment, by reasonably setting the weight of the return spring 323 and the counterweight 322, the resonant frequencies of the gate arm 20 and the spring damper 32 can be made inconsistent, reducing the swing speed and amplitude of the gate arm 20 in strong winds, mitigating metal fatigue of the gate arm 20, and extending the service life of the gate arm 20.

[0038] In some embodiments, such as Figure 7 and Figure 8 As shown, two spring dampers 32 are provided, and the two spring dampers 32 are distributed along the width direction of the gate arm 20. This further increases the weight of the moving end of the gate arm 20, and also further counteracts the swing amplitude of the gate arm 20. In other embodiments, the number of spring dampers 32 can be 3, 4, 5, or even more. Their distribution can be along the width direction, thickness direction, or length direction of the gate arm 20. In some embodiments, such as... Figure 9 As shown, the middle part of the spring damper 32 is connected to the end of the gate arm 20.

[0039] In some embodiments, such as Figure 10 As shown, the damping element 30 includes an elastic rod 331 and a pendulum 332; The elastic rod 331 is located at the end of the gate arm 20 away from the gate body 10, and the elastic rod 331 extends along the length of the gate arm 20; The pendulum 332 is located at the end of the elastic rod 331 furthest from the gate arm 20. Under crosswind conditions, the gate arm 20 swings back and forth, and the elastic rod 331 and pendulum 332 swing together with it. Due to inertia, the pendulum 332 experiences a delay, thus offsetting the swing amplitude of the gate arm 20. When the gate arm 20 returns to its original position, the pendulum 332 moves in the opposite direction under the action of the elastic rod 331, which also offsets the swing speed of the gate arm 20. In a specific embodiment, by setting appropriate weights for the elastic rod 331 and the pendulum 332, the resonant frequencies of the gate arm 20 and the damping element 30 can be made inconsistent, reducing the swing speed and amplitude of the gate arm 20 in strong winds, mitigating metal fatigue of the gate arm 20, and extending its service life.

[0040] In some embodiments, such as Figure 4As shown, the damping component 30 also includes a damping cylinder 34 and damping fluid filled within the damping cylinder 34. The middle portion of the damping cylinder 34 is connected to the damping ring 31, and both ends of the damping cylinder 34 are located on opposite sides of the gate arm 20 in the thickness direction. The movement of the damping fluid within the damping cylinder 34 reduces the swing amplitude of the gate arm 20. Specifically, the damping cylinder 34 is filled with at least one-third of its volume with damping fluid. The movement of the damping fluid counteracts the swing speed of the gate arm 20, thereby reducing metal fatigue of the gate arm 20 and extending its service life.

[0041] In some embodiments, such as Figures 10 to 12 As shown, the damping element 30 also includes at least one elastic rod damper 33. The elastic rod damper 33 includes an elastic rod 331 and a pendulum 332. The elastic rod 331 is connected to the damping ring 31, and the pendulum 332 is connected to the end of the elastic rod 331 away from the damping ring 31. Due to the elasticity of the elastic rod 331 and the weight of the pendulum 332, one end of the elastic rod 331 is relatively heavy. When subjected to strong wind, the pendulum 332 will swing with the swing of the gate arm 20. However, due to inertia, there is a lag, that is, the pendulum 332 will be delayed due to inertial motion, thereby offsetting the swing amplitude of the gate arm 20. When the gate arm 20 resets, the pendulum 332 moves in the opposite direction under the action of the elastic rod 331, which can also offset the swing speed of the gate arm 20.

[0042] In some embodiments, such as Figure 12 As shown, two elastic rod dampers 33 are provided, and the two elastic rod dampers 33 are distributed along the width direction of the gate arm 20. In other embodiments, the two elastic rod dampers 33 are distributed along the thickness direction of the gate arm 20.

[0043] In some embodiments, the ratio of the distance between the damping element and the gate body to the length of the gate arm is 0.7 to 0.9:1. According to the lever principle, by placing the damping element further away from the gate body, the influence of the damping element's own weight on the gate arm can be significantly increased.

[0044] Secondly, embodiments of this application provide a barrier gate system, including a gate arm device, a sensing device (not shown in the figure), and an electronic control device (not shown in the figure). The gate arm device described in the first aspect; The sensing device is installed inside the barrier gate body. The sensing device is used to sense vehicles entering and / or leaving the preset position and generate a raising or lowering signal. The electronic control unit is installed inside the barrier gate body to receive raising or lowering signals and control the gate arm to rise or fall. This allows vehicles to pass through the barrier gate quickly and conveniently, achieving unmanned management.
