Description

Technical Field

[0001] This invention relates to the field of highway management technology, specifically to lane external control cabinets. Background Technology

[0002] With the development of cloud computing, "cloud toll collection" has become a cutting-edge technology for highway toll stations, enabling lane expansion within a smaller area. It eliminates toll booths and manual toll collection processes, reducing the toll station area and allowing for lane expansion within the existing space. Lane external control cabinets are devices adapted to this operating scenario. The equipment within these cabinets is responsible for lane data acquisition and control, housing servers, brake controllers, power supplies, and switching components. It interfaces downwards with laneside equipment to acquire data and control related devices; and upwards with edge servers, acting as a protocol gateway to upload data packets and receive and parse downlink commands.

[0003] Since lane-side control cabinets are generally located next to the brakes, it is difficult to avoid the possibility of collisions in car accidents. Currently, lane-side control cabinets on the market are ordinary cabinets that cannot withstand impacts. If a collision occurs, the internal electrical equipment will be severely damaged.

[0004] Technologies such as the prefabricated substation with integrated primary and secondary systems disclosed in Chinese patent document CN202310428971.5, which uses airbags on the outside of the cabinet to resist impacts, suffer from the problem that the exposed airbags are vulnerable to damage from sharp objects, thus losing their impact resistance. A collision-resistant distribution cabinet disclosed in Chinese patent document CN202320074156.9 uses a spring mechanism for cushioning, but the spring mechanism generally requires a large storage space (i.e., a long spring) to achieve a good cushioning effect. If the spring is short and the required storage space is small, the cushioning effect is negligible. Furthermore, when the spring mechanism acts as a cushioning device for preventing car collisions, it exerts a rigid force on the car, posing a risk of injury to the car and its occupants. Summary of the Invention

[0005] The purpose of this invention is to provide a lane external control cabinet, in which an internal airbag inflates upon impact to protect the lane external control cabinet.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The lane external control cabinet includes a cabinet body and electrical equipment installed inside the cabinet body. The cabinet body is provided with a first partition plate that divides the cabinet body into upper and lower spaces. The upper space is the electrical space and the lower space is the protective component space. The electrical space houses the electrical equipment, and the protective component space houses the airbag inflation assembly. The airbag inflation assembly includes an impact force transmission mechanism and an airbag inflation mechanism; there are four impact force transmission mechanisms, each located at one of the four positions of the square lane exterior control cabinet. The impact force transmission mechanism includes a first lever and a second lever; several horizontally evenly distributed vertically arranged openings are made on the cabinet wall corresponding to the protective space, and several first levers pass through the corresponding openings and are connected to the opening shaft, so that the contact ends of several first levers are located outside the cabinet, and the transmission ends of the first levers are located inside the protective space; the transmission ends of the first levers are higher than the contact ends of the first levers.

[0007] The middle part of the second lever is connected to the inner wall of the cabinet shaft. One end of the second lever is located above the transmission end of the first lever, and the other end is located above the telescopic plate. The transmission ends of the first levers in the four directions are set above the same telescopic plate. The airbag inflation mechanism includes a telescopic plate, a pressure sensor, and a gas generator; the telescopic plate includes a telescopic column and the aforementioned telescopic plate body located at the bottom of the telescopic column; the gas generator is connected to the airbag inlet through a pipe; the pressure sensor transmits a signal to the controller when it receives pressure, and the controller outputs a control signal to the gas generator; the gas generator rapidly inflates the airbag. The airbag is housed in a recess on the outer wall of the cabinet.

[0008] As a preferred technical solution, the transmission ends of several first levers are connected as one unit by a connecting rod; the second lever has a plate-shaped structure.

[0009] As a preferred technical solution, the receiving slot hinge is connected to a slot door.

[0010] As a preferred technical solution, the cabinet has a door on the front, the height of which is higher than the height of the first partition. The receiving groove is an annular groove located on the outer wall of the cabinet corresponding to the electrical space, and between the cabinet door and the first partition.

[0011] As a preferred technical solution, the bottom of the cabinet is also equipped with casters; the casters are connected to a wheel frame.

[0012] The bottom of the cabinet is provided with wheel holes, the size of which is larger than that of the caster wheels; the wheel frame passes through the wheel hole into the protective space and is fixedly connected to the transmission end of the first lever; when the contact end of the first lever presses against the cabinet, the transmission end of the first lever moves upward, driving the wheel frame to move upward, so that the caster wheels are retracted into the cabinet, and the bottom of the cabinet is placed stably on the ground; When the contact end of the first lever is pulled outwards from the cabinet, the transmission end of the first lever moves downwards, causing the wheel frame to move downwards, so that the caster wheel is outside the cabinet and the cabinet is lifted by the caster wheel.

[0013] As a preferred technical solution, each side of the cabinet is equipped with two fixing rings of the same height, and each fixing ring is equipped with a fixing lock.

[0014] Two fixed rings are located on both sides of a plurality of first levers on the surface; the fixed lock includes a fixed rod and ring locks located at both ends of the fixed rod; the two ring locks are respectively locked on the fixed rings, and when locked on the fixed rings, the fixed rod crosses the plurality of first levers laterally and is located below the first levers.

[0015] As a preferred technical solution, the cabinet installation process is as follows: The casters lift the cabinet, placing it outside the cabinet body; When the cabinet reaches the designated position, lock the locking lock on the fixing ring, press the first lever contact end inward, and perform the wheel frame lifting operation until the first lever contact end can no longer be pulled. At this time, the cabinet is placed on the ground. After the cabinet is stably placed and installed, remove the locking ring.

[0016] Compared with existing technologies, it has the following advantages: In this invention, a retractable airbag is used to inflate upon impact to protect the lane external control cabinet, thereby preventing the airbag from being easily damaged by sharp objects when it is located on the outside and kept in an inflated state.

[0017] In this invention, the cabinet door is positioned above the first partition plate because the car itself has a certain height, requiring the airbag to be positioned at a certain height. However, the lane-external control cabinet also needs to accommodate electrical equipment, requiring sufficient space, and the cabinet door needs to be able to be opened. Therefore, considering all these factors, the cabinet door is higher than the partition plate, ensuring sufficient space for the electrical equipment. The annular receiving groove is located on the outer wall of the cabinet corresponding to the electrical space, making the airbag height appropriate. The cabinet door can be opened without affecting the annular integrated airbag.

[0018] In this invention, the pressure sensor is placed inside the cabinet, and the impact force is transmitted through an impact force transmission mechanism. This compresses the pressure sensor inside the cabinet, thereby controlling the airbag inflation. The reason for not placing the pressure sensor directly on the outer wall of the cabinet in contact with the vehicle is that the lane control cabinet is an outdoor device that is exposed to external environmental factors such as thunderstorms, leading to poor stability and potential airbag inflation failure. Therefore, this invention chooses to place the pressure sensor inside the cabinet and use an impact force transmission mechanism to transmit the impact force to the pressure sensor. Furthermore, pressure sensors directly impacted by a vehicle would generally be directly damaged. In this invention, the stroke of the first lever is limited by the opening, reducing the possibility of pressure sensor damage.

[0019] In this invention, the angle of the first lever can be changed, and the height of the casters at the bottom of the cabinet can also be controlled, making it easy to move the cabinet and facilitate replacement, maintenance and inspection.

[0020] In this invention, the cooperation between the fixing lock and the fixing ring ensures that when installing a fixed cabinet and retracting the casters into the cabinet, there will be no accidental operation that would cause the airbag to inflate. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Conversely, this application covers any substitutions, modifications, equivalent methods, and schemes made within the spirit and scope of this application as defined in the claims. Furthermore, to provide the public with a better understanding of this application, certain specific details are described in detail below. However, this application can be fully understood by those skilled in the art even without these detailed descriptions.

[0025] Example 1: As Figure 1-2 As shown, the lane external control cabinet includes a cabinet body and electrical equipment housed within it. A first partition divides the cabinet into upper and lower spaces; the upper space is defined as the electrical space, and the lower space as the protective component space 6. The electrical space houses the electrical equipment; however, it can be further divided by several second partitions for zoned placement of the equipment. The protective component space 6 houses the airbag inflation assembly. The electrical equipment includes switch components, lane external controllers, power supplies, wiring, and other structural components.

[0026] Specifically, the control cabinet has a door 1, a display screen 4, and a camera 3 on its front. When the door 1 is opened, the electrical space inside the control cabinet is exposed. The bottom of the door 1 is higher than the height of the first partition. Therefore, there is a height gap between the first partition and the door 1 on the front of the cabinet.

[0027] A square-shaped receiving groove is provided on the outer wall of the cabinet corresponding to the electrical space. The height of the receiving groove is between the first partition plate and the door 1. This receiving groove is used to hide the airbag. Since the airbag is a thin, small ball when it is not inflated, the size of the receiving groove can be designed to be very small.

[0028] A ring-shaped airbag is housed within a circular receiving groove. This groove is square-shaped, meaning it has four positions, each with a door 2. The door 2 is connected to a hinge 5 on the outer wall of the cabinet above the receiving groove. When the airbag inflates, it pushes open the door 2, expands out of the receiving groove, and collides with the car that hits it.

[0029] The airbag inflation assembly includes an impact force transmission mechanism and an airbag inflation mechanism; the impact force transmission mechanism comprises four groups, each located in one of the four directions of the square lane exterior control cabinet. Since the four groups of impact force transmission mechanisms have identical structures, this embodiment only describes the group located on the front of the cabinet.

[0030] The impact force transmission mechanism includes a first lever 10 and a second lever 12. Several horizontally evenly distributed, vertically arranged strip-shaped openings are formed on the cabinet wall corresponding to the protective space 6. Several first levers 10 pass through the corresponding strip-shaped openings and are connected to the shaft of the strip-shaped opening (the friction at the shaft connection is very large, requiring a large external force to achieve the rotation of the first lever 10). The contact ends of the first levers 10 are located outside the cabinet, while the transmission ends of the first levers 10 are located inside the protective space. The transmission ends of the first levers 10 are higher than their contact ends.

[0031] The transmission ends of several first levers 10 are connected as one unit by connecting rods. The second lever 12 is a plate-shaped structure, with its middle part axially connected to the inner wall of the cabinet where the protective space 6 is located, thus forming a lever structure. One end of the second lever 12 is located above the transmission end of the first lever 10, and the other end is located in the airbag inflation mechanism, above the telescopic plate 11. When the contact end of the first lever 10 is impacted, the contact end of the first lever 10 presses towards the cabinet, causing its transmission end to tilt upwards, lifting one end of the second lever 12, while the other end of the second lever 12 descends, causing the telescopic plate 11 to descend.

[0032] The airbag inflation mechanism includes a telescopic plate 11, a pressure sensor, and a gas generator. The telescopic plate 11 includes a telescopic column and a telescopic plate body located at the bottom of the telescopic column. The top of the telescopic column is fixed to the bottom of the first partition plate. A pressure sensor is located below the telescopic plate body. The gas generator is connected to the airbag inlet through a pipe with a valve. The pressure sensor transmits a signal to the controller when it receives pressure, and the controller outputs a control signal to the gas generator. The resistance wire inside the gas generator heats up, causing the chemical substances inside the gas generator to vaporize and rapidly inflate the airbag, causing the airbag to expand and pop out of the receiving groove.

[0033] In this embodiment, the pressure sensor is placed inside the cabinet, and the impact force is transmitted through an impact force transmission mechanism. This compresses the pressure sensor inside the cabinet, thereby controlling the airbag inflation. The reason for not placing the pressure sensor directly on the outer wall of the cabinet in contact with the car is that the lane control cabinet is an outdoor device that is exposed to external environmental factors such as thunderstorms, which can lead to poor stability and potential airbag inflation failure. Therefore, this embodiment chooses to place the pressure sensor inside the cabinet and use an impact force transmission mechanism to transmit the impact force to the pressure sensor. Furthermore, a pressure sensor directly impacted by a car would generally be destroyed. In this embodiment, the stroke of the first lever 10 is limited by the strip-shaped opening, reducing the possibility of pressure sensor damage.

[0034] In this embodiment, the other end of the second lever 12 corresponding to each position on the cabinet is located above the same telescopic plate 11. This structure allows the impact on the cabinet from any direction to be transmitted to the same pressure sensor, simplifying the structure.

[0035] As a preferred embodiment, an electronic lock may be provided between the slot door 2 and the receiving slot. The opening and closing of the electronic lock is controlled by a controller. Under normal circumstances, the electronic lock is closed. When the camera 3 detects a car and converts the collected image data into distance data through the controller, if the distance between the car and the cabinet is detected to be lower than a set value, the electronic lock is opened.

[0036] This method ensures that no one will intentionally open the door 2 and damage the airbag without a car collision.

[0037] Example 2: The difference between this example and Example 1 is that, in order to facilitate the movement and maintenance of the lane external control cabinet by staff, a caster wheel 14 is also provided at the bottom of the lane external control cabinet. The caster wheel 14 is connected to a wheel frame 13.

[0038] The bottom of the cabinet (i.e., the bottom of the protective space 6) is provided with a wheel hole 15, the size of which is larger than that of the caster wheel 14; the wheel frame 13 passes through the wheel hole 15 into the protective space 6 and is fixedly connected to the connecting rod of the transmission end of the first lever 10 mentioned above. That is, the first lever 10 can also drive the wheel frame 13 to move.

[0039] Specifically, when the contact end of the first lever 10 presses against the cabinet, the transmission end of the first lever 10 moves upward, which drives the wheel frame 13 to move upward, causing the caster wheel 14 to retract into the cabinet, at which point the bottom of the cabinet is placed stably on the ground.

[0040] When the contact end of the first lever 10 is pulled outwards from the cabinet, the transmission end of the first lever 10 moves downwards, causing the wheel frame 13 to move downwards, so that the universal wheel 14 is located outside the cabinet, and the cabinet is lifted by the universal wheel 14, at which point the cabinet can be moved easily.

[0041] Because the friction between the first lever 10 and the cabinet is very large, mechanical equipment is used to assist in changing the position of the contact end of the first lever 10.

[0042] Initially, to facilitate moving the cabinet, the casters 14 lift the cabinet and place it outside the cabinet. When it reaches the designated position, the cabinet is placed flat on the ground, and the casters 14 need to be retracted into the cabinet. At this time, the contact end of the first lever 10 needs to be pressed inward, causing the transmission end of the first lever 10 to lift the wheel frame 13. To prevent the inward pressure control of the contact end of the first lever 10 from being out of control and causing the height of the transmission end of the first lever 10 to exceed the critical point, the transmission end of the first lever 10 applies a pushing force to one end of the second lever 12, ultimately causing the telescopic plate 11 to press against the pressure sensor, thereby causing the airbag to inflate erroneously. Therefore, in this embodiment, a fixing ring 7 and a fixing lock are also provided. When the cabinet reaches the designated position, the fixing lock is first locked onto the fixing ring 7, and then the wheel frame 13 is lifted.

[0043] Specifically, each side of the cabinet is equipped with two fixing rings 7 at the same height, and each fixing ring 7 is equipped with a fixing lock.

[0044] There are two fixing rings 7 on each side, and the two fixing rings 7 are located on both sides of several first levers 10 on that side; for example Figure 3 As shown, the fixed lock includes a fixed rod 8 and ring locks 9 located at both ends of the fixed rod 8. The two ring locks 9 are respectively locked onto the fixed ring 7. When locked onto the fixed ring 7, the fixed rod 8 laterally crosses several first levers 10 and is located below the first levers 10.

[0045] If the contact end of the first lever 10 is pushed inward at this point, the angle of inward push is limited by the fixing rod 8, so that it cannot be pushed inward further after reaching a certain angle. This ensures that the height of the transmission end of the first lever 10 will not exceed the critical point. After the cabinet is stably placed and installed, the fixing lock is removed. At this time, the contact end of the first lever 10 can be pushed inward again, so that when impacted, the impact force can be transmitted to the pressure sensor.

[0046] The present invention can be well implemented according to the above embodiments. It is worth noting that, based on the above structural design, even some non-substantial improvements made to the present invention to solve the same technical problem fall within the protection scope of the present invention.
