Description

Technical Field

[0001] This utility model relates to the field of autonomous driving technology, specifically to an auxiliary device for precise stopping of autonomous buses at bus stops. Background Technology

[0002] Autonomous driving refers to the ability of vehicles to operate autonomously without human intervention, achieved through artificial intelligence, sensors, and other technologies. Autonomous vehicles rely on the collaborative efforts of artificial intelligence, computer vision, radar, monitoring devices, and global positioning systems to enable computers to operate motor vehicles safely and automatically without any active human intervention.

[0003] When buses equipped with autonomous driving functions arrive at a stop, they need to stop precisely within the stop. This not only facilitates passengers getting on and off the bus but also avoids affecting the normal driving of other vehicles on the road. The normal operation of autonomous buses is thanks to various sensors on the vehicle. Among them, the sensors installed on the side of the vehicle for stopping at the platform are usually fixed on the vehicle and remain stationary. As the vehicle moves, the angle between it and the platform changes, which can easily cause the bus to lose its fixed stopping position and thus fail to stop precisely. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for precise stopping of autonomous buses at bus stops. By adjusting the angle of the sensor group, after the receiving device is installed on the bus, the sensor group is always directly connected to the signal transmitter on the bus stop. Then, the positional relationship between the vehicle and the bus stop is accurately calculated based on the angle between the mounting post and the bus. This prevents the sensor group from failing to accurately connect with the transmitter on the bus stop due to angle issues, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic bus stop precision stopping assistance device, comprising:

[0006] Receiving equipment installed on buses;

[0007] The receiving device includes a sensor array for precise positioning.

[0008] And the mounting housing located outside the sensor array and installed on the outside of the bus;

[0009] The front end of the mounting housing is provided with a horizontal groove. Inside the mounting housing, a mounting shaft is vertically rotatably mounted via a bearing. A mounting post is fixed to the outside of the mounting shaft. The end of the mounting post away from the mounting shaft extends toward the horizontal groove. A mounting seat that fits against the inner wall of the mounting housing is fixed to the outside of the mounting post. The sensor group is respectively mounted on the mounting post and the mounting seat.

[0010] The mounting housing is equipped with a yaw drive assembly that rotates the mounting shaft.

[0011] Preferably, the yaw drive assembly includes a drive motor mounted on the back of the inner cavity of the mounting housing, the output shaft of the drive motor is fixed with a drive pulley, a driven pulley is fixed on the outer side of the mounting shaft, and a linkage belt is drivingly connected to the outer sides of the drive pulley and the driven pulley.

[0012] Preferably, a mounting plate is integrally formed on the outer side of the mounting housing, and a protective frame is mounted on the outer side of the mounting plate, with the protective frame located on the outer side of the mounting housing.

[0013] Preferably, a support plate is fixed to one end of the protective frame near the mounting plate, and mounting screws are provided on the back of the mounting plate, the mounting screws passing through the mounting plate and threadedly connected to the protective frame.

[0014] Preferably, a protective cover is installed inside the transverse groove, and multiple sets of sensors in the sensor group are on the same horizontal plane as the transverse groove.

[0015] Preferably, the mounting plate has multiple sets of mounting holes around its perimeter, and the mounting housing has a wire through hole on its back side.

[0016] Preferably, the surfaces of the mounting column and the mounting base are provided with mounting grooves, and the sensor groups are respectively fixedly embedded in the mounting grooves.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a mounting housing to install the sensor group on the outside of the bus. Then, driven by the oscillation drive component inside the mounting housing, the mounting shaft can swing to adjust the angle between the mounting column and the bus. This allows the sensor group to be angled and accurately dock with the signal transmitter on the platform, avoiding deviations in vehicle parking caused by the angle of the sensor group.

[0019] 2. This utility model provides overall protection for the exterior of the mounting housing through a protective frame, preventing the mounting housing from being exposed and damaged by collisions. At the same time, the protective cover protects the horizontal groove, preventing dust and rainwater from entering the interior of the mounting housing and causing circuit failures.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-4 The device shown is an automated driving bus stop precision stopping assistance device, comprising:

[0027] Receiving equipment installed on buses;

[0028] The receiving device includes a sensor group 1 for precise positioning;

[0029] And the mounting housing 2 located outside the sensor group 1 and installed on the outside of the bus;

[0030] The front end of the mounting housing 2 is provided with a transverse groove 3. The mounting shaft 4 is vertically mounted inside the mounting housing 2 via a bearing. A mounting post 5 is fixed on the outside of the mounting shaft 4. The end of the mounting post 5 away from the mounting shaft 4 extends toward the transverse groove 3. A mounting seat 6 that fits against the inner wall of the mounting housing 2 is fixed on the outside of the mounting post 5. The sensor group 1 is respectively mounted on the mounting post 5 and the mounting seat 6.

[0031] The mounting housing 2 is equipped with a yaw drive assembly 7 that rotates the mounting shaft 4.

[0032] The sensor assembly 1 is installed on the outside of the bus by mounting housing 2. Then, under the drive of the oscillation drive component 7 inside the mounting housing 2, the mounting shaft 4 can swing to adjust the angle between the mounting column 5 and the bus, so that the sensor assembly 1 can be angled and accurately docked with the signal transmitter on the platform, avoiding deviations in vehicle parking caused by the angle of the sensor assembly 1.

[0033] Among them, such as Figure 2 As shown:

[0034] The yaw drive assembly 7 includes a drive motor 71 mounted on the back of the inner cavity of the mounting housing 2. The output shaft of the drive motor 71 is fixed with a drive pulley 72, and a driven pulley 73 is fixed on the outer side of the mounting shaft 4. A linkage belt 74 is connected to the outer sides of the drive pulley 72 and the driven pulley 73. The drive motor 71 drives the drive pulley 72 to rotate, and then the linkage belt 74 drives the driven pulley 73 to rotate, thereby driving the mounting shaft 4 to rotate, so that the mounting seat 6 and the mounting column 5 yaw inside the mounting housing 2 to adjust the angle of the sensor group 1.

[0035] Furthermore, such as Figure 1 and Figure 4 As shown:

[0036] An integrally formed mounting plate 8 is formed on the outer side of the mounting housing 2. A protective frame 9 is mounted on the outer side of the mounting plate 8. The protective frame 9 is located on the outer side of the mounting housing 2 and is installed through the mounting plate 8 to protect the mounting housing 2 from collision damage.

[0037] Preferred, such as Figure 1 and Figure 4 As shown:

[0038] A support plate 10 is fixed to one end of the protective frame 9 near the mounting plate 8. A mounting screw 11 is provided on the back of the mounting plate 8. The mounting screw 11 passes through the mounting plate 8 and is threadedly connected to the protective frame 9. The support plate 10 increases the contact area between the protective frame 9 and the mounting plate 8, making the installation of the protective frame 9 more stable. At the same time, the mounting screw 11 facilitates the disassembly and assembly of the protective frame 9.

[0039] It is worth noting that, such as Figure 1 As shown:

[0040] A protective cover 12 is installed inside the transverse groove 3. Multiple sets of sensors in the sensor group 1 are on the same horizontal plane as the transverse groove 3. The protective cover 12 is used to isolate the inside and outside of the mounting housing 2, preventing dust and rainwater from entering the interior of the mounting housing 2 from the transverse groove 3.

[0041] In a further preferred embodiment, such as Figure 4 As shown:

[0042] The mounting plate 8 has multiple sets of mounting holes 13 around its perimeter, and the mounting housing 2 has a wire hole 14 on its back. The mounting holes 13 facilitate the mounting and fixing of the mounting housing 2 with the mounting plate 8. At the same time, the wire hole 14 on the back of the mounting housing 2 is used for connecting the wiring harness inside the mounting housing 2 with the wiring harness inside the bus.

[0043] In addition, such as Figure 3 As shown:

[0044] Mounting slots are provided on the surfaces of mounting post 5 and mounting base 6. Sensor group 1 is fixedly embedded in the mounting slots. The mounting slots facilitate the installation of various sensors in sensor group 1, while ensuring that mounting base 6 and mounting post 5 operate normally within the mounting housing 2.

[0045] In practical use, the protective frame 9 is installed on the mounting plate 8 using the mounting screws 11 to protect the mounting housing 2. Then, the mounting housing 2 is installed on the bus through the mounting holes 13. When the bus approaches the station, the drive motor 71 drives the drive pulley 72 to rotate. Then, the drive pulley 72 drives the driven pulley 73 to rotate through the linkage belt 74, driving the mounting shaft 4. Subsequently, the mounting column 5 fixed to the mounting shaft 4 drives the mounting seat 6 to swing inside the mounting housing 2, so that the sensor group 1 is aligned with the signal transmitter on the platform through the transverse groove 3. As the vehicle enters the station, the mounting shaft 4 rotates continuously, and the sensor group 1 is accurately positioned with the platform to ensure accurate stopping.

[0046] Sensor group 1 includes distance sensors and angle sensors, which use advanced algorithms to calculate and integrate data, enabling vehicles to accurately stop at the platform.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
