Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and more specifically, to a vehicle driving obstacle recognition module. Background Technology

[0002] Obstacle recognition sensors play a crucial role in modern technology, not only enhancing system safety and intelligence but also opening up new possibilities for various industries. With continuous technological advancements, the application scope of these sensors is expanding, enabling them to play a vital role in more fields. For example, in the automotive industry, obstacle recognition sensors are typically installed to improve driving safety. During driving, these sensors monitor designated areas in real time, providing pre-collision warnings and reducing the probability of collisions. Currently, obstacle recognition sensors are generally directly bolted to the vehicle frame. Over long-term vehicle operation, these bolts are prone to loosening, leading to the obstacle recognition sensor becoming loose or even falling off, resulting in a high failure rate and posing safety hazards. Utility Model Content

[0003] The purpose of this utility model includes, for example, providing a car driving obstacle recognition module that can reduce the probability of loosening and falling off, improve the connection firmness, reduce the difficulty of disassembly and assembly, and reduce maintenance costs.

[0004] The embodiments of this utility model can be implemented as follows:

[0005] In a first aspect, this utility model provides a vehicle driving obstacle recognition module, including a base, a sensor body, and a locking device, wherein:

[0006] The base has an assembly hole on its top surface, a positioning groove on the wall of the assembly hole, and a snap-fit ​​groove on its top surface that connects to the positioning groove; the base is used to fix itself to the vehicle frame.

[0007] The sensor body has a snap-fit ​​post on its outer shell, which enters the positioning groove from the snap-fit ​​slot. The outer shell and the positioning groove are rotatably fitted around a preset axis. The outer shell and the positioning groove are fixed relative to each other in a direction perpendicular to the preset axis. The bottom of the outer shell has a locking groove, which is eccentrically set to the preset axis.

[0008] The locking device includes a drive mechanism and a locking pin. The drive mechanism is mounted on the base, and the locking pin is mounted on the drive mechanism. The drive mechanism is used to drive the locking pin to extend into or leave the locking groove.

[0009] In an optional embodiment, a limiting member is provided on the bottom wall of the positioning groove. The limiting member is used to contact the locking post during the rotation of the sensor body in the first rotation direction, so as to limit the locking post from continuing to rotate in the first rotation direction.

[0010] In an optional embodiment, one of the limiting member and the snap-fit ​​post is a magnet, and the other is a magnet or a metal part.

[0011] In an optional embodiment, the outer surface of the snap-fit ​​post is provided with a limiting groove, which is used to engage with the limiting member.

[0012] In an optional embodiment, the outer contour of the cross-section of the snap-fit ​​post is set to be circular, and the cross-section is set to be a plane perpendicular to the length direction of the snap-fit ​​post.

[0013] In an optional embodiment, the driving mechanism includes a telescopic component and a transmission head. The telescopic component is mounted on the base, and the transmission head is provided with a first driving inclined surface. The transmission head is mounted on the telescopic end of the telescopic component.

[0014] The locking pin is provided with a second driving inclined surface, and the locking pin and the base are slidably engaged in the extension direction of the preset axis; the first driving inclined surface contacts the second driving inclined surface, so that the linear reciprocating motion of the transmission head is converted into the reciprocating lifting motion of the locking pin, thereby allowing the locking pin to insert into or leave the locking groove.

[0015] In an optional embodiment, the assembly hole is configured as a blind hole, and a first channel extending along the extension direction of the preset axis is provided on the bottom wall of the assembly hole, and the locking pin is slidably inserted into the first channel; a second channel communicating with the first channel is provided on the outer side of the base, and the transmission head is slidably inserted into the second channel.

[0016] In an optional embodiment, the telescopic assembly is configured as a cylinder, a hydraulic cylinder, or an electric actuator.

[0017] In an optional implementation, the sensor body is configured as a lidar, ultrasonic sensor, infrared sensor, or camera.

[0018] In an optional embodiment, the end face of the locking pin for extending into the locking groove is configured as a tapered surface.

[0019] The beneficial effects of this utility model embodiment include, for example:

[0020] In summary, the vehicle obstacle recognition module provided in this embodiment fixes the base to the vehicle frame or other locations, and then installs the sensor body onto the base. Specifically, the snap-fit ​​pin on the sensor body's outer shell is first aligned with the snap-fit ​​groove. Then, the sensor body's outer shell is inserted into the mounting hole, allowing the snap-fit ​​pin to enter the groove. Next, the sensor body is rotated, causing the snap-fit ​​pin to rotate relative to the groove and enter the positioning recess. After the snap-fit ​​pin rotates a certain angle, it is misaligned with the groove. At this point, the snap-fit ​​pin is limited by the two sidewalls of the positioning recess, preventing the sensor body from detaching from the mounting hole. Simultaneously, a locking pin is inserted into the locking groove on the outer shell using a drive mechanism. Due to the eccentric arrangement of the locking groove and the sensor body's rotation axis, the locking pin, once inserted into the locking groove, restricts the sensor body's rotation relative to the base. The snap-fit ​​pin will not rotate to a position directly opposite the groove, and the sensor body will not automatically detach from the mounting hole. The sensor body's position is stable and reliable, ensuring safe and reliable operation. When it is necessary to replace the sensor body, first disengage the locking pin from the locking groove, then rotate the sensor body so that the snap-fit ​​pin is aligned with the snap-fit ​​groove, and then pull out the sensor body. The operation is convenient and flexible. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] In existing technologies, obstacle recognition sensors, such as lidar, infrared sensors, or cameras, are typically fixed to the vehicle frame or other locations using screws or bolts when applied to automobiles. Over time, the vibrations generated by the vehicle's operation are transmitted to the obstacle recognition sensor, which can easily cause the bolts to loosen, leading to the sensor falling off. Furthermore, when the fasteners become loose, the vibrations experienced by the obstacle recognition sensor intensify, producing abnormal noises, shortening its lifespan, and increasing operating costs.

[0035] In view of this, the designers have provided a vehicle driving obstacle recognition module that can improve the stability and reliability of the connection structure, making it less prone to loosening and falling off; it is also less likely to produce abnormal noises due to increased vibration, less prone to damage due to vibration, and has a long service life.

[0036] Please refer to Figures 1-3 This embodiment provides a vehicle driving obstacle recognition module, including a base 100, a sensor body 200, and a locking device 300. The base 100 has a mounting hole 101 on its top surface, a positioning groove 102 on the hole wall, and a snap-fit ​​groove 103 communicating with the positioning groove 102 on its top surface. The base 100 is used to fix itself to a vehicle frame. The sensor body 200 has a snap-fit ​​post 220 on its outer shell 210. The snap-fit ​​post 220 enters the positioning groove 102 from the snap-fit ​​groove 103, and the outer shell 210 and the positioning groove 102 are rotatably engaged around a preset axis 001. The outer shell 210 and the positioning groove 102 are relatively fixed in a direction perpendicular to the preset axis 001. The bottom of the outer shell 210 has a locking groove 211, which is eccentrically positioned relative to the preset axis 001. The locking device 300 includes a drive mechanism 310 and a locking pin 320. The drive mechanism 310 is mounted on the base 100, and the locking pin 320 is mounted on the drive mechanism 310. The drive mechanism 310 is used to drive the locking pin 320 to extend into or out of the locking groove 211.

[0037] As described above, the assembly method of the vehicle driving obstacle recognition module provided in this embodiment is as follows:

[0038] First, the base 100 can be fixed to the vehicle frame, for example, by welding the base 100 to the vehicle frame with the mounting hole 101 on the base 100 facing outwards. Align the snap-fit ​​pin 220 on the housing 210 of the sensor body 200 with the snap-fit ​​groove 103, and then insert the housing 210 of the sensor body 200 into the mounting hole 101, so that the snap-fit ​​pin 220 enters the snap-fit ​​groove 103. Next, rotate the sensor body 200, so that the snap-fit ​​pin 220 rotates relative to the snap-fit ​​groove 103 and enters the positioning groove 102. After the snap-fit ​​pin 220 rotates a certain angle, the snap-fit ​​pin 220 is misaligned with the snap-fit ​​groove 103. At this time, the snap-fit ​​pin 220 is limited by the two sidewalls of the positioning groove 102, and the sensor body 200 will not come out of the mounting hole 101. Then, the locking pin 320 is inserted into the locking groove 211 on the housing 210 by the drive mechanism 310. Since the locking groove 211 is eccentrically set with the rotation axis of the sensor body 200, the locking pin 320 can restrict the rotation of the sensor body 200 relative to the base 100 after it is inserted into the locking groove 211.

[0039] During use, the locking pin 220 will not rotate to a position directly opposite the locking groove 103, preventing the sensor body 200 from automatically dislodging from the mounting hole 101. The sensor body 200 remains stably positioned, ensuring safe and reliable operation. When replacing the sensor body 200, first disengage the locking pin 320 from the locking groove 211, then rotate the sensor body 200 until the locking pin 220 is aligned with the locking groove 103. The sensor body 200 can then be easily and flexibly removed. Because the sensor body 200 achieves axial and radial positioning through the positioning groove 102 and circumferential positioning through the locking pin 320, its freedom of movement in three-dimensional space is restricted, resulting in a stable position, preventing loosening, and ensuring safe and reliable operation.

[0040] The following embodiments illustrate the details of the vehicle driving obstacle recognition module of this application by way of example.

[0041] Please refer to Figure 1 In this embodiment, optionally, the vehicle driving obstacle recognition module includes a base 100, a sensor body 200, and a locking device 300. The base 100 is used to fix it to the vehicle frame, the sensor body 200 is mounted on the base 100, and the locking device 300 is mounted on the base 100. The locking device 300 can lock the sensor body 200, making it difficult for it to fall off the base 100.

[0042] Please refer to Figure 3Optionally, the base 100 can be configured as a circular block with a circular top surface. An assembly hole 101 is provided on the top surface; the assembly hole 101 is a circular blind hole and is coaxially arranged with the base 100. A positioning groove 102 is provided on the circumferential wall of the assembly hole 101. The positioning groove 102 is an arc-shaped groove extending circumferentially along the assembly hole 101. For example, in this embodiment, the positioning groove 102 can be a quarter-circular arc-shaped groove. A first channel 104 is provided on the bottom wall of the assembly hole 101. The first channel 104 can be a circular channel extending along the axial direction of the assembly hole 101. The axis of the first channel 104 is eccentrically positioned to the axis of the assembly hole 101, meaning there is a gap between the axis of the first channel 104 and the axis of the assembly hole 101. A locking groove 103 communicating with the positioning groove 102 is provided on the top surface of the base 100. The locking groove 103 can be a rectangular groove. The design of the slot 103 allows it to penetrate the upper wall of the positioning groove 102, effectively creating a notch in the upper wall. A second channel 105 is provided on the outer circumferential surface of the base 100. The second channel 105 extends radially along the mounting hole 101. The second channel 105 can be a circular channel and communicates with the first channel 104. The second channel 105 is arranged approximately perpendicular to the first channel 104.

[0043] Furthermore, a limiting member 110 is provided within the positioning groove 102, and the limiting member 110 may be provided with a cylindrical protrusion. In addition, the limiting member 110 may be provided with a magnet or a metal part.

[0044] It should be understood that during assembly, the circular bottom surface of the base 100 can be welded and fixed to the vehicle frame for positioning. The base 100 can be fixed to the front and rear bumpers, in which case the vehicle obstacle recognition module can be used for the recognition and warning of obstacles in front of and behind the vehicle when reversing.

[0045] Optionally, the sensor body 200 can be configured as a lidar, ultrasonic sensor, infrared sensor, or camera. For example, when the sensor body 200 is configured as a lidar, its model can be Velodyne HDL-32E or Velodyne VLS-128, etc.; when the sensor body 200 is configured as an ultrasonic sensor, its model can be Bosch UPA0001 or Valeo Ultrasonic Sensors, etc. This embodiment does not list them all.

[0046] Please refer to Figure 1 or Figure 2Optionally, the sensor body 200 has a housing 210, which is generally circular. A snap-fit ​​post 220 is provided on the outer circumferential surface of the housing 210. The snap-fit ​​post 220 can be cylindrical, meaning its cross-sectional profile is circular, and the cross-section is a plane perpendicular to the length direction of the snap-fit ​​post 220. When the sensor body 200 is assembled with the base 100, the snap-fit ​​post 220 is aligned with the snap-fit ​​groove 103. Then, the sensor body 200 enters the assembly hole 101, and the snap-fit ​​post 220 enters the positioning groove 102 through the notch formed at the snap-fit ​​groove 103. Subsequently, force can be applied to the sensor body 200 to rotatably engage the housing 210 and the positioning groove 102 around a preset axis 001, where the preset axis 001 is the axis of the assembly hole 101. When the outer shell 210 rotates to be misaligned with the slot 103, the locking post 220 is limited by the groove wall of the positioning groove 102, so that the outer shell 210 and the positioning groove 102 are relatively fixed in a direction perpendicular to the preset axis 001. At the same time, the outer shell 210 contacts the circumferential hole wall of the assembly hole 101 to achieve radial limitation.

[0047] Furthermore, a locking groove 211 is provided at the bottom of the outer casing 210. The locking groove 211 is eccentrically positioned with respect to the preset axis 001, that is, the locking groove 211 and the preset axis 001 are spaced apart in the radial direction of the outer casing 210. The locking groove 211 can be configured as a circular groove.

[0048] Please refer to Figure 1 Furthermore, the outer peripheral surface of the snap-fit ​​post 220 is configured as a limiting groove 221, which can be a circular groove. It should be understood that the snap-fit ​​post 220 can be a magnet or a metal component. After the snap-fit ​​post 220 enters the snap-fit ​​groove 103, when the outer shell 210 rotates relative to the positioning groove 102 in the first rotation direction, the snap-fit ​​post 220 can approach the limiting member 110, and the limiting member 110 can be inserted into the limiting groove 221. The snap-fit ​​post 220 and the limiting member 110 are magnetically connected, serving as a preliminary positioning element. At this time, with the cooperation of the limiting member 110 and the limiting groove 221, the outer shell 210 will not continue to rotate in the first rotation direction, indicating that the rotation angle of the outer shell 210 meets the requirements. Simultaneously, due to the magnetic connection between the limiting member 110 and the snap-fit ​​post 220, the outer shell 210 will not automatically rotate relative to the base 100 in a second rotation direction opposite to the first rotation direction, facilitating subsequent locking of the sensor body 200 using the locking device 300.

[0049] It is worth noting that, in order to achieve the magnetic connection between the locking post 220 and the limiting member 110, one of the limiting member 110 and the locking post 220 must be a magnet, and the other must be a magnet or a metal part. In other words, at least one of them must be a magnet, and the other can be a magnet or a metal part in order to achieve the magnetic adsorption function.

[0050] In this embodiment, optionally, the locking device 300 includes a driving mechanism 310 and a locking pin 320. The driving mechanism 310 is mounted on the base 100, and the locking pin 320 is mounted on the driving mechanism 310. The driving mechanism 310 is used to drive the locking pin 320 to extend into or leave the locking groove 211.

[0051] Please refer to Figure 1 Optionally, the drive mechanism 310 includes a telescopic component 311 and a transmission head 312. The telescopic component 311 can be configured as a cylinder, hydraulic cylinder, or electric push rod, etc., and can be designed for manual, remote control, or a combination of both, depending on the requirements. The telescopic component 311 is mounted on the outer peripheral surface of the base 100. The transmission head 312 is provided with a first driving inclined surface 3121. The transmission head 312 is mounted on the telescopic end of the telescopic component 311, and the transmission head 312 is slidably mounted in the second channel 105. The transmission head 312 can reciprocate linearly along the length of the second channel 105 under the drive of the telescopic component 311.

[0052] Optionally, one end of the locking pin 320 is provided with a tapered surface 321, and the other end of the locking pin 320 is provided with a second driving inclined surface 322. The locking pin 320 is slidably installed in the first channel 104, and the sliding direction of the locking pin 320 relative to the first channel 104 is consistent with the extension direction of the preset axis 001. The end of the locking pin 320 with the tapered surface 321 is close to the mounting hole 101, and correspondingly, the second driving inclined surface 322 of the locking pin 320 is away from the mounting hole 101 and can contact the first driving inclined surface 3121. With this design, when the telescopic component 311 drives the transmission head 312 to slide, the first driving inclined surface 3121 contacts the second driving inclined surface 322, which can convert the linear reciprocating motion of the transmission head 312 into the reciprocating lifting motion of the locking pin 320, thereby allowing the locking pin 320 to insert into or leave the locking groove 211. That is, when the outer shell 210 rotates to the limit member 110 and the locking post 220 contact the limit, it indicates that the outer shell 210 has rotated to the correct position and the locking groove 211 is just above the locking pin 320. Then, the telescopic component 311 drives the transmission head 312 to move, so that the locking pin 320 moves upward and can be inserted into the locking groove 211. Since the locking pin 320 is eccentrically set with the axis of the mounting hole 101, the outer shell 210 can be restricted from rotating in the second rotation direction in the mounting hole 101. The locking post 220 will not move to the position of the locking groove 103, and the sensor body 200 will not automatically rotate out of the mounting hole 101.

[0053] It is worth noting that, since the end of the locking pin 320 is a tapered surface 321, one end of the tapered surface 321 is less likely to interfere with the opening of the locking groove 211, making insertion into the locking groove 211 smoother.

[0054] It should be understood that when the sensor body 200 needs to be repaired or replaced, the telescopic component 311 is used to drive the transmission head 312 to retract, so that it loses its support for the locking pin 320. The locking pin 320 can leave the locking groove 211 under the action of gravity. At this time, the outer shell 210 can be rotated so that the locking post 220 is rotated to the position aligned with the locking groove 103. Finally, the sensor body 200 can be pulled out of the mounting hole 101.

[0055] Please refer to Figure 4 To prevent the locking pin 320 from getting stuck in the locking groove 211, a first stop 120 can be provided in the first channel 104. A spring 130 is provided at the bottom of the annular retaining ring, and the spring 130 is sleeved on the outside of the locking pin 320. A second stop 323 is provided on the outside of the locking pin 320, and the spring 130 is clamped between the first stop 120 and the second stop 323. When the transmission head 312 drives the locking pin 320 to rise and insert into the locking groove 211, the spring 130 is compressed. When the transmission head 312 loses support for the locking pin 320, the locking pin 320 can automatically leave the locking groove 211 under the action of the spring 130.

[0056] Furthermore, when the housing 210 is inserted into the mounting hole 101, a portion of the housing 210 can be exposed through the mounting hole 101. An operating part can be provided on the portion of the housing 210 exposed through the mounting hole 101. The operating part can be a slot, and a tool can be inserted into the slot to facilitate the rotation of the housing 210, saving time and effort.

[0057] The vehicle driving obstacle recognition module provided in this embodiment has a stable and reliable sensor body 200 that is not easy to fall off, making it safe and reliable to use; it is also easy to disassemble and assemble, and has low maintenance costs.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
