Description

Technical Field

[0001] This utility model relates to the field of articulated train technology systems, specifically to an installation structure for an integrated articulated device. Background Technology

[0002] In the field of urban transportation, with the development of the social economy and the improvement of people's living standards, the number of motor vehicles has increased dramatically, leading to a deterioration of the urban traffic environment, a decrease in road network efficiency, and slow traffic on main and auxiliary roads. The existing articulated design of intelligent rail transit (IRT) vehicles integrates the advantages of modern trams and buses. IRT vehicles employ virtual trajectory following control technology, using onboard sensors to identify virtual track lines on the road surface, achieving track-like operation. The articulated design allows IRT vehicles to maintain a small turning radius while preserving the vehicle's length, solving the turning difficulties caused by excessively long vehicles.

[0003] The sensors in the articulated devices of intelligent rail vehicles are split-type, making the installation process cumbersome, and the existing angle sensor housings have weak shielding effects against EMC interference.

[0004] A search revealed CN202323327726.X, which discloses a concealed vehicle-mounted sensor and a vehicle. The concealed vehicle-mounted sensor includes a sensor integration box, a transmission rod, and a driver. The sensor integration box has a first face and a second face facing each other. The first face has a detection surface. The sensor integration box is hinged to the vehicle body, allowing it to rotate relative to the vehicle body. When the sensor integration box is in a first rotated position, the detection surface is located inside the vehicle body; when the sensor integration box is in a second rotated position, the detection surface is located outside the vehicle body. One end of the transmission rod is hinged to the sensor integration box near the first face. The driver is fixed to a first target area on the inner surface of the vehicle body and has a drive rod capable of reciprocating along a direction forming a first angle with the first target area. The drive rod is hinged to the end of the transmission rod away from the sensor integration box.

[0005] The above solution does not solve the problem of complicated installation of split sensors. Therefore, a solution that is easy to install, has consistency between the two side-mounted sensors, and enhances the sensor's resistance to EMC interference is designed, which has great practical significance and economic value. Utility Model Content

[0006] To address the shortcomings of existing technologies, an integrated hinged device mounting structure is provided. Through rational structural design, multiple sensors (central and lateral positions) of the hinged sensor are integrated into a single housing, allowing the two lateral sensors to share the same acquisition board and interface output. This simplifies the installation and maintenance process for end users, improves the consistency of the two lateral sensors, and enhances the sensor's resistance to EMC interference.

[0007] The technical means adopted by this utility model to solve the above problems are as follows: An integrated hinge device mounting structure is disclosed, comprising a housing and a sensor. The housing includes an upper housing and a lower housing forming an integral receiving cavity. The upper housing includes multiple mounting holes for mounting a rotating shaft structure. The rotating shaft structure includes an exposed end and a connecting end. The exposed end extends out of the housing and connects to a transmission mechanism. The connecting end connects to the sensor. By setting multiple mounting holes, multiple sensors are integrated into the same housing. By setting the position of the rotating shaft structure, multiple sensors can reuse the same acquisition board and interface output, thereby improving sensor consistency.

[0008] This utility model discloses an integrated hinge device mounting structure that combines the housing, sensor, rotating shaft structure, and transmission mechanism into a highly integrated unit. Multiple sensors are mounted on the same housing, reducing the cost of multiple mold openings for the housing. The assembly process is simplified, requiring only a single adjustment of the relative angle between the housing and the upper crossbar to complete the assembly.

[0009] Furthermore, the outer shell has a convex-shaped mounting surface; the central axis of the pivot structure forms a triangular region with a first pivot structure and a second pivot structure; the first pivot structure includes two pivots symmetrical on the same side; and the two first extended ends are connected to a swing arm structure.

[0010] Furthermore, the second extended end of the second rotating shaft structure is connected to the hinged disc beam; a connecting rod structure connects the hinged disc beam and the swing arm structure, so that the first rotating shaft structure and the second rotating shaft structure move together.

[0011] Furthermore, the swing arm structure includes a variable diameter annular structure that gradually narrows from the pivot structure to the connecting rod structure; the swing arm structure and the connecting rod structure are connected by a ball joint structure; the connecting rod structure and the hinged disc beam are connected by a ball joint structure.

[0012] Furthermore, a first limiting groove is provided on the side of the upper housing, which cooperates with a second limiting groove provided on the side of the lower housing to form a clearance area for the sensor electrical interface.

[0013] Furthermore, the mounting holes of the upper housing are provided with weight-reducing cavities, which include a cavity and / or a reinforcing connecting plate disposed between the cavities.

[0014] Furthermore, the mounting hole has three through holes, and the center of each through hole is coaxially arranged with the rotating shaft structure installed in the through hole.

[0015] Furthermore, the sensor includes a central sensor and a side sensor, the side sensor being disposed at the connecting end of the first rotating shaft structure; the central sensor being disposed at the connecting end of the second rotating shaft structure.

[0016] Furthermore, the central sensor and the side sensor are connected to the hinge controller via a wiring harness.

[0017] Furthermore, the hinged disc crossbeam is provided with a groove structure at intervals.

[0018] The advantages of this utility model compared to the prior art are: This utility model's integrated hinge device uses an installation structure to mount multiple sensors on the same housing, reducing the cost of multiple mold openings for the housing. It simplifies the assembly process, allowing assembly to be completed by adjusting the relative angle between the housing and the upper crossbar only once.

[0019] The integrated hinge device of this invention uses a metal shell that encloses the mounting structure in one piece, which enhances the sensor's anti-interference capability. Simultaneously, the PGND (protective ground) terminals in the circuit are reliably connected to each other through the metal shell, avoiding potential differences between the PGND terminals of independent sensors.

[0020] The installation structure for the integrated hinge device of this utility model is applicable to both the structure of the hinge device sensor integration and the structure of the hinge device sensor and controller integration.

[0021] Therefore, this mounting structure simplifies the cumbersome steps of sensor installation, is highly versatile, easy to assemble, and has broad market prospects. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0030] like Figures 1-6 As shown, the integrated hinge device mounting structure of this embodiment breaks through the traditional split design of sensors, and installs multiple sensors on the same housing, making the entire structure integrated.

[0031] Specifically, the system includes a housing and sensors. The housing comprises an integrated cavity consisting of an upper housing 1 and a lower housing 2 made of metal, with a U-shaped mounting surface on the outside. The upper housing 1 includes multiple mounting holes 11 for mounting a rotating shaft structure 3. The rotating shaft structure 3 includes an exposed end and a connecting end. The exposed end extends out of the housing and connects to the transmission mechanism; the connecting end connects to the sensors 4. By setting multiple mounting holes 11, multiple sensors 4 are integrated into the same housing. By setting the position of the rotating shaft structure 3, multiple sensors 4 can reuse the same acquisition board and interface output, thereby improving sensor consistency. In this embodiment, the mounting holes 11 have three through holes, and three sensors are coaxially arranged with the center of the through holes and the rotating shaft structure 3 installed in the through holes. Among them, the sensors 4 include a central sensor 41 and a side sensor 42. The side sensor 42 is located at the connecting end of the first rotating shaft structure 31; the central sensor 41 is located at the connecting end of the second rotating shaft structure 32. The central sensor 41 and the side sensor 42 are connected to the hinge controller via a wiring harness.

[0032] The transmission mechanism in this embodiment includes the interconnected transmission of the swing arm structure 5, the hinged disc beam 6, and the connecting rod structure 7.

[0033] In this embodiment, the central axis of the rotating shaft structure 3 forms a triangular region with a first rotating shaft structure 31 and a second rotating shaft structure 32. The first rotating shaft structure 31 includes two rotating shafts symmetrical on the same side. The two first extended ends 311 are connected to the swing arm structure 5. The second extended end 321 of the second rotating shaft structure 32 is connected to the hinged plate beam 6. A connecting rod structure 7 connects the hinged plate beam 6 and the swing arm structure 5, so that the first rotating shaft structure 31 and the second rotating shaft structure 32 move together.

[0034] In this embodiment, the swing arm structure 5 includes a variable diameter annular structure that gradually narrows from the pivot structure 3 to the connecting rod structure 7; the side closer to the pivot structure 3 is wider and the side connecting the connecting rod structure 7 is relatively narrow, which can effectively transmit the output power of the pivot structure 3 to the connecting rod structure 7 and ensure transmission stability and reliability.

[0035] As a preferred solution, the swing arm structure 5 and the connecting rod structure 7 are connected by a ball joint; the connecting rod structure 7 and the hinged disc beam 6 are also connected by a ball joint. This allows for connections and changes in angles between the transmission structures. Combined with the side position sensor 42 and the central sensor 41, it effectively enables intelligent control of the entire structure.

[0036] Furthermore, the two side sensors 42 are located on the same side, share a common acquisition board and reuse the interface output, which improves the consistency of the two side sensors and enhances the sensor's anti-EMC interference capability.

[0037] A first limiting groove 12 is provided on the side of the upper housing 1, which cooperates with a second limiting groove 21 provided on the side of the lower housing 2 to form a clearance area for the sensor electrical interface 8. A weight-reducing cavity 9 is provided between the mounting holes 11 of the upper housing 1. The weight-reducing cavity 9 includes a cavity 91 and / or a reinforcing connecting plate 93 disposed between the cavities. In this embodiment, the weight-reducing holes 9 are symmetrically arranged to ensure uniform stress distribution throughout the structure and improve reliability. As a preferred design, in this embodiment, the center is a rectangular through hole, and the two sides are rectangular through holes with reinforcing connecting plates 93, which ensures strength while achieving a lightweight design of the entire housing.

[0038] Correspondingly, the lower housing 2 is provided with a groove at the mounting hole 11 that communicates with the structure of the mounting hole 11, so as to install the sensor 4 and the rotating shaft structure. In this embodiment, the mounting hole 11 is a circular through hole and the groove is a cylindrical groove. The two are coaxial and have the same diameter. The diameter of the hole is slightly larger than the outer diameter of the rotating shaft structure to effectively fix the rotating shaft structure.

[0039] The hinged plate beam 6 is provided with groove structures 61 at intervals, and a recessed positioning groove 62 is provided above the second rotating shaft structure 32 for locking the fixing bolts in the positioning groove 62.

[0040] The housing is designed as a single unit based on the dimensions of the mounting interface. The housing design is optimized for the PCB according to the sensor's technical requirements, and the mounting points and the gap between the upper and lower housings and the board are determined to prevent the housing from affecting the internal magnetic circuit.

[0041] The specific installation steps are as follows: Place the three sensors at the mounting positions on the lower housing 2, then assemble the rotating shaft structure 3 to form the sensor assembly, and align it with the hinge plate beam 6 and the transmission mechanism, ensuring it aligns with the mounting holes 11 on the hinge plate beam 6; insert the corresponding screws for positioning, but do not tighten them yet. Rotate the sensor's hinge plate beam 6 so that the mounting holes at both ends of the upper hinge plate beam 6 align with the mounting holes on the hinge plate. Insert the screws and tighten the upper hinge plate beam 6. Finally, tighten the housing positioning screws to complete the physical interface installation. After the sensor housing is installed, with the hinge plate unpowered, connect the central sensor and side sensors to the hinge controller via wiring harnesses. Installing multiple sensors on the same housing reduces the cost of multiple housing mold openings. The assembly process is simplified, requiring only one adjustment of the relative angle between the housing and the upper crossbar to complete the assembly.

Commonly known structures and characteristics in the solutions are not described in detail here.
