Description

Technical Field

[0001] This utility model relates to the field of passenger door swing arm technology, specifically to a passenger door swing arm bracket. Background Technology

[0002] The passenger door swing arm is an important component of the bus passenger door system. It is usually installed at the connection between the door and the body, with one end connected to the door and the other end connected to a fixed point on the body. Its main function is to realize the opening and closing of the door. It drives the door to open and close by rotating around the fixed point. Before actual use, the passenger door swing arm needs to be installed with a bracket.

[0003] Currently, when using passenger door swing arm brackets, there is a lack of auxiliary detection mechanisms. Usually, the passenger door needs to rotate the swing arm to a specified angle to achieve the opening and closing action. However, due to factors such as wear and tear from long-term use, the swing arm angle is easily insufficient, which not only affects the opening and closing quality of the passenger door but also poses certain safety hazards. Therefore, a passenger door swing arm bracket is proposed to add an auxiliary detection mechanism. By using flipping, sliding, and detection methods, the range of swing arm rotation can be detected and processed to ensure the stability and safety of the swing arm rotation operation, thereby improving the usage effect. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is a passenger door swing arm bracket, including a bracket, an auxiliary component and a detection component. A mounting base is rotatably connected inside the bracket, an auxiliary component is rotatably connected to the inner side of the mounting base, and a detection component is provided inside the bracket located inside the mounting base.

[0006] The detection component includes a lead screw, a corresponding ball bearing slider is sleeved around the lead screw, a positioning plate is bolted to one side of the ball bearing slider, and a displacement sensor corresponding to the positioning plate is bolted to the bottom of the bracket.

[0007] By adopting the above technical solution, the lead screw, ball block slider, positioning plate and displacement sensor can be used to add an auxiliary detection mechanism to detect the rotation range of the passenger door arm by sliding and rotating, so as to improve the stability and safety of use.

[0008] Specifically, the auxiliary component includes a rotating plate with a protrusion at its end.

By using the plug-in, rotation and snap-fit ​​methods, the stability and safety of the passenger door swing arm during disassembly and assembly can be improved, and the operation can be more convenient and faster.

[0010] Specifically, both ends of the lead screw are bolted to driven gears, and the driven gears are rotatably connected to the bracket via a rotating shaft. The top of the bracket is bolted to a torque sensor, and the driven gears are rotatably connected to the input end of the torque sensor via a rotating shaft.

[0011] By adopting the above technical solution, the driven gear and torque sensor can be used to perform secondary detection using the rotation angle, thereby improving the accuracy of auxiliary detection.

The outer periphery of the rotating seat is bolted to a drive gear, and mounting holes are provided on both sides of the mounting base.

[0013] By adopting the above technical solution, the rotating seat and the driving gear can drive the driven gear to rotate for detection through meshing connection, and the mounting hole facilitates the fixed connection of the passenger door rotating arm to the mounting seat.

[0014] Specifically, mounting plates are welded to both sides of the bracket.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To facilitate the detection and processing of the boom's rotation range, ensure the stability and safety of the boom's operation, and thus improve its performance, such as... Figure 1-3 As shown, the passenger door swing arm bracket of this utility model includes a bracket 1, an auxiliary component 3 and a detection component 4. A mounting base 2 is rotatably connected inside the bracket 1, and the auxiliary component 3 is rotatably connected to the inner side of the mounting base 2. The detection component 4 is provided inside the bracket 1 located inside the mounting base 2.

[0027] The detection component 4 includes a lead screw 401, and a corresponding ball slider 402 is sleeved around the lead screw 401. A positioning plate 403 is bolted to one side of the ball slider 402, and a displacement sensor 404 corresponding to the positioning plate 403 is bolted to the bottom of the bracket 1.

[0028] In use, an auxiliary detection mechanism can be added through the lead screw 401, ball slider 402, positioning plate 403 and displacement sensor 404. The rotation range of the passenger door arm can be detected by sliding and rotating, so as to improve the stability and safety of use.

[0029] To improve ease of assembly and disassembly, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes the auxiliary component 3, which includes a rotating plate 301. The end of the rotating plate 301 is provided with a protrusion 302. The top and bottom of the rotating plate 301 are both connected to a rotating shaft 303 by welding. The rotating plate 301 is rotatably connected to the mounting base 2 through the rotating shaft 303. A coil spring 304 is sleeved around the rotating shaft 303. One end of the coil spring 304 is connected to the rotating shaft 303 by welding, and the other end of the coil spring 304 is connected to the mounting base 2 through a slot.

[0030] In use, the auxiliary clamping mechanism can be added by rotating plate 301, rotating shaft 303, protrusion 302 and coil spring 304. By using the plug-in, rotation and snap-fit ​​method, the stability and safety of the passenger door swing arm during disassembly and assembly are improved, and the operation is more convenient and faster.

[0031] For example, such as Figure 2 As shown, the present invention also includes a driven gear 405 bolted to both ends of the lead screw 401, and the driven gear 405 is rotatably connected to the bracket 1 via a rotating shaft. A torque sensor 406 is bolted to the top of the bracket 1, and the driven gear 405 is rotatably connected to the input end of the torque sensor 406 via a rotating shaft.

[0032] In use, the driven gear 405 and torque sensor 406 can be used to perform secondary detection by utilizing the rotation angle, thereby improving the accuracy of auxiliary detection.

[0033] For example, such as Figure 4 As shown, the present invention also includes a rotating seat 201 bolted to the top and bottom of the mounting base 2, and the rotating seat 201 is mounted in the bracket 1 by bearings. The outer periphery of the rotating seat 201 is bolted to a drive gear 202, and mounting holes 203 are provided on both sides of the mounting base 2.

[0034] In use, the driven gear 405 can be rotated by the rotating seat 201 and the driving gear 202 through meshing connection for detection. The passenger door swing arm is easily fixedly connected to the mounting seat 2 through the mounting hole 203, and the driving gear 202 is meshed with the driven gear 405.

[0035] For example, such as Figure 1As shown, the present invention also includes mounting plates 5 welded to both sides of the bracket 1.

[0036] During use, the mounting plate 5 facilitates the pre-bolt fixing of the bracket 1.

[0037] In use, the operator first fixes the bracket 1 with bolts using the mounting plate 5, then moves the passenger door swing arm to the outside of the mounting base 2, so that the rotating plate 301 is inserted into the corresponding reserved hole of the swing arm. The spring force of the coil spring 304 drives the rotating shaft 303 and the rotating plate 301 to rotate outward, so that the protrusion 302 is inserted into the groove of the swing arm to complete the auxiliary limiting treatment. Then, the passenger door swing arm is fixedly connected with bolts through the mounting hole 203, so as to improve the stability and convenience of operation.

[0038] During the operation of the passenger door swing arm, the rotation of the swing arm drives the rotating seat 201 and the driving gear 202 to rotate synchronously. At the same time, through the meshing connection of the driven gear 405, the lead screw 401 can reciprocate. The ball block slider 402 drives the positioning plate 304 to move vertically back and forth. The displacement sensor 404 detects the displacement distance of the positioning plate 403, which can realize the detection of the swing arm's rotation range. Meanwhile, the torque sensor 406 performs secondary detection through the rotation angle of the driven gear 405, thereby ensuring the landing rate of the passenger door swing arm, improving the stability and safety of use. The overall structure is simple and the use is more reasonable and reliable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
