Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle barrier technology, specifically to a wiring structure for a light strip power cord of a vehicle barrier. Background Technology
[0002] With the increasing prevalence of automated management in parking lots, toll booths, and other similar locations, automatic barrier gates (also known as traffic gates) have become widely used. To improve visibility at night or in low-light conditions and ensure traffic safety, the current common practice is to install LED light strips or other luminous markings on the barrier arm. This design effectively warns vehicles and pedestrians, significantly improving the safety of the equipment.
[0003] Currently, the power supply method for the boom light strip is typically as follows: the power connection cable passes through the bottom of the boom near the rotation axis, i.e., on the side of the housing, then through a mounting hole at the corresponding position in the housing, and finally connects to the internal power system. However, this traditional wiring method has two obvious technical drawbacks:
[0004] First, there is a risk of wear and tear from movement. The boom arm needs to frequently rise and fall during operation. During this process, the power cable passing between the boom arm and the housing is repeatedly pulled and bent. The power cable will continuously rub against the edges of the exit holes on the boom arm and the mounting holes on the housing. Over time, the outer insulation layer of the power cable is easily worn through, exposing the internal wires. This can lead to short circuits, power outages, and even electrical leakage hazards, significantly reducing the reliability of the equipment.
[0005] Secondly, there is a risk of environmental aging. Power cable sections partially exposed outside the enclosure are constantly subjected to the outdoor environment, directly exposed to erosion from natural factors such as sunlight, rain, temperature fluctuations, and ultraviolet radiation. This causes the power cable insulation material to age faster, become brittle, and crack, resulting in a rapid decline in its electrical performance and mechanical strength. Consequently, this significantly shortens the power cable's lifespan and increases maintenance costs and replacement frequency.
[0006] In summary, the existing power connection methods for barrier light strips are insufficient in terms of reliability and durability, hindering the improvement of overall product quality. Therefore, a new power connection structure is urgently needed to address the issues of power cable wear and environmental aging. Utility Model Content
[0007] To address the aforementioned technical shortcomings, this invention provides a wiring structure for the power cord of a wheel chock, thereby extending the service life of the power cord.
[0008] This utility model discloses a power supply wiring structure for a light strip in a vehicle barrier, including a housing and a barrier arm. A main shaft is fixedly connected to the root of the barrier arm. A mounting hole is provided on the side wall of the housing, and a bearing seat is provided inside the mounting hole. The bearing is installed in the bearing seat, and the main shaft is supported in the bearing. A through hole is provided on the main shaft along its central axis, and the through hole on the main shaft communicates with the interior of the barrier arm. A light strip is provided on the barrier arm, and a power supply wire is provided inside the barrier arm. One end of the power supply wire is electrically connected to the light strip, and the other end of the power supply wire passes through the through hole on the main shaft and is electrically connected to the power supply inside the housing.
[0009] The principle behind the above technical solution lies in changing the traditional external wiring to internal wiring: by opening a through hole in the center of the main shaft, which is fixedly connected to the stop arm, it becomes a sealed power transmission channel; the power cable of the light strip inside the stop arm passes directly through this central hole in the main shaft from its base, and then enters the housing through this hole to connect to the power supply. This design places the dynamic power supply line entirely within the internal space of the stop arm and the main shaft, allowing it to move synchronously and smoothly with the main shaft and the stop arm throughout the entire lifting and rotation process. This completely avoids friction and wear caused by relative movement between the power cable and the edge of the external hole, and also completely isolates it from harsh outdoor environments such as wind and sun, fundamentally solving the problem of power cable wear and aging.
[0010] To reduce friction between the power cord and the spindle, a first mounting base is installed at the end of the spindle furthest from the stop arm. A second mounting base is installed on the housing at the corresponding position. A gap exists between the first and second mounting bases. A countersunk hole is located at the center of the side of the first mounting base opposite to the second mounting base, and this countersunk hole is coaxial with the spindle. A conductive block is installed on the second mounting base at the position corresponding to the first countersunk hole. A first brush slides within the first countersunk hole, and a first spring is installed between the first brush and the bottom of the first countersunk hole. The first brush contacts the conductive block. The first mounting base and the second mounting base... A second countersunk hole is provided on the outer side of the opposite end face of the mounting base. A second brush is slidably installed in the second countersunk hole. A second spring is installed between the second brush and the bottom of the second countersunk hole. A conductive ring is provided on the end face of the second mounting base that is closer to the first mounting base. The conductive ring is coaxial with the spindle. The second brush is in contact with the conductive ring. The positive terminal of the power cord passes through the first mounting base and is electrically connected to the first brush. The negative terminal of the power cord passes through the first mounting base and is electrically connected to the second brush. The positive wire of the power supply inside the box passes through the second mounting base and is electrically connected to the conductive block. The negative wire of the power supply inside the box passes through the second mounting base and is electrically connected to the conductive ring.
[0011] The power cable wiring structure for a parking barrier light strip, as described in this invention, offers several advantages. It eliminates the inherent defects of traditional external wiring methods by completely embedding the power cable within the main shaft and passing it through the central through-hole. This eliminates external friction during the rotation of the parking barrier arm, thus eradicating cable wear caused by mechanical movement. Furthermore, the fully enclosed wiring path completely isolates the power cable from outdoor environments such as wind, rain, and sunlight, significantly slowing down the aging process. This design significantly improves the reliability and durability of the power cable, effectively preventing short circuits and open circuits, fundamentally extending its service life, and reducing maintenance costs.

[0015] Example 1:
[0016] like Figure 1 , 2As shown, this utility model discloses a wiring structure for a light strip power cord for a vehicle barrier, including a housing 1 and a barrier arm 3. A main shaft 5 is fixedly connected to the root of the barrier arm 3. A mounting hole is provided on the side wall of the housing 1, and a bearing seat 7 is provided inside the mounting hole. A bearing 6 is installed in the bearing seat 7, and the main shaft 5 is supported in the bearing 6. A through hole is provided on the main shaft 5 along its central axis, and the through hole on the main shaft 5 communicates with the interior of the barrier arm 3. A light strip 2 is provided on the barrier arm 3, and a power cord is installed inside the barrier arm 3. Power cord 4 has one end electrically connected to the light strip 2, and the other end passes through a through hole on the main shaft 5. A first mounting seat 8 is located at the end of the main shaft 5 furthest from the stop arm 3. A second mounting seat 9 is located on the housing 1 at the position corresponding to the first mounting seat 8. A gap is left between the first mounting seat 8 and the second mounting seat 9. A countersunk hole is located at the center of the end face of the first mounting seat 8 opposite to the second mounting seat 9. The first countersunk hole is coaxial with the main shaft 5. A countersunk hole is located at the center of the end face of the second mounting seat 9 corresponding to the first mounting seat 9. A conductive block 13 is installed at the countersunk hole position. A first brush 12 is slidably installed inside the first countersunk hole. A first spring 11 is installed between the first brush 12 and the bottom of the first countersunk hole. The first brush 12 is in contact with the conductive block 13. A second countersunk hole is installed on the outer side of the end face of the first mounting base 8 opposite to the second mounting base 9. A second brush 15 is slidably installed inside the second countersunk hole. A second spring 14 is installed between the second brush 15 and the bottom of the second countersunk hole. The second mounting base 9 is attached to the first mounting base. A conductive ring 16 is provided on the end face of 8. The conductive ring 16 is coaxial with the main shaft 5. The second brush 15 is in contact with the conductive ring 16. The positive terminal of the power line 4 passes through the first mounting base 8 and is electrically connected to the first brush 12. The negative terminal of the power line 4 passes through the first mounting base 8 and is electrically connected to the second brush 15. The positive terminal of the power supply 10 inside the housing 1 passes through the second mounting base 9 and is electrically connected to the conductive block 13. The negative terminal of the power supply 10 inside the housing 1 passes through the second mounting base 9 and is electrically connected to the conductive ring 16.
[0017] The principle of the above technical solution lies in changing the traditional external wiring to internal wiring: by opening a through hole in the center of the main shaft 5, which is fixedly connected to the stop arm 3, it becomes a sealed power transmission channel; the power line 4 of the light strip 2 inside the stop arm 3 passes directly into the center hole of the main shaft 5 from its root, and enters the housing 1 through the hole to connect to the power supply 10. This design places the dynamic power supply line entirely within the internal space of the stop arm 3 and the main shaft 5, allowing it to move synchronously and smoothly with the main shaft 5 and the stop arm 3 during the entire lifting and rotating process of the stop arm 3. This completely avoids the friction and wear caused by the relative movement between the power line 4 and the edge of the external hole, and also completely isolates it from harsh outdoor environments such as wind and sun, fundamentally solving the problem of wear and aging of the power line 4.
