Description

Technical Field

[0001] This application relates to the field of automotive decontamination technology, and more particularly to a decontamination nozzle and a vehicle. Background Technology

[0002] With the continuous development of vehicle technology, vehicles can be equipped with multimodal sensing devices such as cameras and sensors for road condition data collection. However, because these devices are frequently exposed to rain, snow, sandstorms, or muddy conditions, they are easily contaminated. Therefore, cleaning nozzles are needed to clean these devices. Currently, cleaning nozzles are typically bolted to the device's support structure, but after a period of operation, they tend to loosen, causing them to drift horizontally. This indicates that the current cleaning nozzles have poor fixation. Utility Model Content

[0003] This application provides a cleaning nozzle and a vehicle to solve the problem of poor fixing effect of current cleaning nozzles.

[0004] To solve the above problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a decontamination nozzle, comprising:

[0006] A fluid delivery pipeline is provided with a fixing member and an abutment member, and the fixing member and the abutment member form a receiving groove. The receiving groove is used to engage with the support member of the multimodal sensing device. The fluid delivery pipeline is used to deliver fluid.

[0007] A nozzle is connected to the first end of the fluid delivery pipeline. The nozzle is positioned toward the multimodal sensing device, and the nozzle outlet is used to spray the fluid, with the spray direction of the fluid being parallel or approximately parallel to the surface to be cleaned set by the multimodal sensing device.

[0008] As an optional implementation, the first end of the abutment is fixedly connected to the fluid delivery pipeline, the second end of the abutment is a free end, and when the support is engaged in the receiving groove, the free end abuts against the support.

[0009] As an alternative implementation, the distance between the abutment and the fluid delivery pipeline gradually increases along the direction from the first end of the abutment to the second end of the abutment.

[0010] As an optional implementation, the cleaning nozzle further includes a mounting plate, which is perpendicular to the fluid delivery pipeline. The fixing member is disposed on the mounting plate, and the abutting member is disposed opposite to or offset from the fixing member.

[0011] As an optional implementation, the support member is provided with a mounting through hole, and the fixing member is adapted to fit into the mounting through hole.

[0012] As an optional implementation, the decontamination nozzle includes N sets of limiting components, each set of limiting components including one fixing member and one abutting member, where N is an integer greater than 1;

[0013] Wherein, when N is 2, the two sets of limiting components are located on opposite side walls of the fluid conveying pipeline; or, when N is 3, the line connecting the fixing parts in the three sets of limiting components is a triangle, and the line connecting the free ends of the abutting parts in the three sets of limiting components is a triangle.

[0014] As an optional implementation, the cleaning nozzle further includes a fluid inlet connector, and the fluid delivery pipeline is sealed and connected to the fluid inlet connector.

[0015] As an optional implementation, the cleaning nozzle further includes a rib, and the rib is at least partially disposed on the fluid inlet connector.

[0016] As an optional implementation, the number of ribs is multiple, and the multiple ribs are distributed at intervals along the axial direction of the fluid inlet pipe joint.

[0017] As an optional implementation, the fluid input pipe joint is further provided with threaded ribs in the axial direction, and the threaded ribs are spaced apart from or adjacent to the ribs.

[0018] As an optional implementation, the rib includes a first rib portion and a second rib portion connected to each other, the first rib portion being disposed on the fluid input pipe joint, and the second rib portion being sleeved on the second end of the fluid delivery pipeline.

[0019] As an optional implementation, the fluid input pipe joint is further provided with a first reinforcing rib plate, and the first reinforcing rib plate is located between the fluid input pipe joint and the mounting plate.

[0020] As an optional implementation, the centerline of the fluid delivery pipeline intersects the centerline of the nozzle, and the angle between the intersections is between 60 and 90 degrees.

[0021] As an optional implementation, the nozzle is detachably connected to the first end of the fluid delivery pipeline.

[0022] As an optional implementation, the inner wall of the nozzle facing the connection end of the fluid delivery pipeline is provided with a protrusion, and the first end of the fluid delivery pipeline is provided with a groove, and the protrusion is adapted to be connected to the groove.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The terms "first," "second," etc., used in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, and the presence of both A and B, both B and C, both A and C, and the presence of A, B, and C.

[0040] Please see Figures 1 to 9 , Figure 1 and Figure 2 These are schematic diagrams of the decontamination nozzles provided in the embodiments of this application, such as... Figure 1 and Figure 2 As shown, and Figures 5 to 7As shown, the decontamination nozzle includes: a fluid delivery pipeline 10 and a nozzle 20. The fluid delivery pipeline 10 is used to deliver fluid. The nozzle 20 is connected to a first end of the fluid delivery pipeline 10 and is used to spray fluid. The nozzle 20 is positioned towards the multimodal sensing device, and the nozzle outlet of the nozzle 20 is used to spray fluid. The direction of fluid spraying is parallel or approximately parallel to the surface of the multimodal sensing device to be decontaminated. The aforementioned approximately parallelism can be understood as the angle between the direction of fluid spraying and the surface to be decontaminated being approximately ±5°. Thus, the multimodal sensing device can be decontaminated using the aforementioned fluid. The aforementioned fluid can be at least one of a liquid fluid and a gaseous fluid. See also... Figure 8 The fluid transport pipeline 10 is equipped with a fixing member 11 and an abutment member 12, see [reference]. Figure 3 and Figure 4 The fixing member 11 and the abutting member 12 form a receiving groove 13. The receiving groove 13 is used to engage with the support member of the multimodal sensing device, so that the connection between the support member and the receiving groove 13 is stable, thereby reducing the movement of the cleaning nozzle along the horizontal direction and enhancing the fixing effect of the cleaning nozzle.

[0041] It should be noted that the specific types of multimodal sensing devices and supporting components are not limited here. Optionally, multimodal sensing devices may include at least one of the following: cameras, LiDAR, and sensors, and supporting components may include at least one of the following: support bases, support plates, support blocks, etc.

[0042] The connection method between the nozzle 20 and the first end of the fluid delivery pipeline 10 is not limited here. Optionally, the nozzle 20 and the first end of the fluid delivery pipeline 10 can be an integrally formed structure, which can enhance the connection strength between the nozzle 20 and the first end of the fluid delivery pipeline 10. Alternatively, the nozzle 20 and the first end of the fluid delivery pipeline 10 can be detachably connected. In this way, a nozzle 20 that is compatible with the lens of the multimodal sensing device can be selected according to its degree of protrusion, and the selected nozzle 20 can be detachably connected to the first end of the fluid delivery pipeline 10, making the replacement and disassembly of the nozzle 20 more convenient, while also saving on usage costs.

[0043] It should be noted that the specific connection method for the detachable connection between the nozzle 20 and the first end of the fluid delivery pipeline 10 is not limited here. Optionally, the inner wall of the connection end of the nozzle 20 facing the fluid delivery pipeline 10 is provided with a protrusion, and the first end of the fluid delivery pipeline 10 is provided with a groove. The protrusion and the groove are adapted to each other. This adaptation connection can be understood as the size and shape of the protrusion and the groove being adapted to each other, so that the protrusion can be more stably engaged in the groove. In this way, the detachable connection between the nozzle 20 and the first end of the fluid delivery pipeline 10 can be achieved more conveniently, and the connection effect between the nozzle 20 and the first end of the fluid delivery pipeline 10 is more stable when the nozzle 20 is connected to the first end of the fluid delivery pipeline 10.

[0044] It should be noted that, optionally, see [link to relevant documentation]. Figure 1 The fluid delivery pipeline 10 may also be provided with a second reinforcing rib 14 to increase the strength and rigidity of the fluid delivery pipeline 10, and the second reinforcing rib 14 may be provided at the position between the nozzle 20 and the fixing member 11.

[0045] As an optional implementation, the first end of the abutment member 12 is fixedly connected to the fluid delivery pipeline 10 to enhance the connection strength between the first end of the abutment member 12 and the fluid delivery pipeline 10. The second end of the abutment member 12 is a free end 121, and when the support member is engaged in the receiving groove 13, the free end 121 abuts against the support member. In this way, the abutment between the free end 121 and the support member can further enhance the limiting effect between the support member and the free end 121, thereby further reducing the horizontal movement of the cleaning nozzle.

[0046] Alternatively, see Figure 1 , Figure 2 and Figure 3 The second end of the abutment 12 is a free end 121, and a positioning element can be provided on the free end 121. The positioning element can be used to abut against the support element. That is, the free end 121 can abut against the support element through the positioning element, thereby further enhancing the limiting effect between the support element and the free end 121. The specific structure of the positioning element is not limited here. For example, the positioning element can be a positioning boss, etc.

[0047] As an optional implementation, see [link to implementation details]. Figure 3 and Figure 4Along the direction from the first end of the abutment 12 to the second end of the abutment 12, the distance between the abutment 12 and the fluid delivery pipeline 10 gradually increases. That is, the abutment 12 can be inclined relative to the fluid delivery pipeline 10. The distance between the first end of the abutment 12 and the fluid delivery pipeline 10 is small, while the distance between the second end of the abutment 12 and the fluid delivery pipeline 10 is large. This makes the distance between the receiving groove 13 and the fluid delivery pipeline 10 larger, avoiding interference with the fluid delivery pipeline 10 when the support is stuck in the receiving groove 13. In other words, it increases the distance between the support and the fluid delivery pipeline 10.

[0048] As an optional implementation, see [link to implementation details]. Figure 1 and Figure 2 The cleaning nozzle also includes a mounting plate 30, which is perpendicular to the fluid delivery pipeline 10. A fixing member 11 is mounted on the mounting plate 30. The fixing member 11 and the mounting plate 30 can be integrally formed, or the fixing member 11 and the mounting plate 30 can be detachably connected. In this way, the mounting plate 30 can make the installation position of the fixing member 11 more flexible. At the same time, by setting the mounting plate 30, the distance between the fixing member 11 and the fluid delivery pipeline 10 can also be increased, thereby avoiding interference to the fluid delivery pipeline 10 when the support member is stuck in the above-mentioned receiving groove 13.

[0049] It should be noted that the abutment 12 and the fixing member 11 are arranged opposite to each other or staggered, which allows the abutment 12 and the fixing member 11 to better form the receiving groove 13. In addition, it also increases the flexibility of the setting position of the abutment 12 and the fixing member 11.

[0050] As an optional implementation, the support member is provided with a mounting through hole, and the fixing member 11 is adapted to fit into the mounting through hole. For example, the fixing member 11 can be inserted into the mounting through hole, and when the fixing member 11 is inserted into the mounting through hole, the fixing member 11 can abut against the inner wall of the mounting through hole. Alternatively, the fixing member 11 can also be interference-fitted with the inner wall of the mounting through hole. In this way, the connection strength between the fixing member 11 and the support member can be further enhanced, thereby further reducing the horizontal movement of the cleaning nozzle, thus enhancing the fixing effect of the cleaning nozzle. At the same time, the overall positioning of the cleaning nozzle can also be achieved.

[0051] As an optional implementation, the cleaning nozzle includes N sets of limiting components, each set of limiting components including a fixing member 11 and an abutment member 12, where N is an integer greater than 1; thus, since multiple sets of limiting components are provided, the connection strength between the cleaning nozzle and the support member can be further enhanced, thereby further reducing the movement of the cleaning nozzle along the horizontal direction, and thus enhancing the fixing effect of the cleaning nozzle.

[0052] Among them, see Figure 1 When N is 2, the two sets of limiting components are located on opposite side walls of the fluid delivery pipeline 10, thereby ensuring a stable connection between the two sets of limiting components and the support, reducing the movement of the cleaning nozzle; or, see Figure 2 When N is 3, the lines connecting the fixing members 11 in the three sets of limiting components form a triangle, and the lines connecting the free ends of the abutting members 12 in the three sets of limiting components also form a triangle. Because triangles have good stability, the connection strength between the cleaning nozzle and the support member is also good, thereby further reducing the horizontal movement of the cleaning nozzle and enhancing its fixing effect.

[0053] As an optional implementation, see [link to implementation details]. Figure 1 and Figure 2 The cleaning nozzle also includes a fluid inlet connector 40, which is sealed and connected to the fluid delivery pipe 10. For example, the fluid inlet connector 40 can be at least partially inserted into the fluid delivery pipe 10, and the outer wall of the fluid inlet connector 40 can abut against the inner wall of the fluid delivery pipe 10. Alternatively, the second end of the fluid delivery pipe 10 can be inserted into the fluid inlet connector 40, and the inner diameter of the fluid inlet connector 40 can be larger than the inner diameter of the fluid delivery pipe 10. Thus, with a constant fluid volume, the larger inner diameter of the fluid inlet connector 40 compared to the fluid delivery pipe 10 effectively increases the fluid velocity and enhances the cleaning effect of the cleaning nozzle.

[0054] As an optional implementation, see [link to implementation details]. Figure 1 , Figure 2 , Figure 3 as well as Figure 9 The cleaning nozzle also includes a raised rib 41, which is at least partially disposed on the fluid inlet pipe connector 40. In this way, the raised rib 41 can prevent the second end of the fluid delivery pipe 10 from being excessively inserted into the fluid inlet pipe connector 40, that is, the raised rib 41 can play a positioning role. In addition, the raised rib 41 can also play a sealing role.

[0055] The specific structure of the rib 41 is not limited here. Optionally, the rib 41 can be a plate-shaped rib, or alternatively, the rib 41 can be a frustum-shaped rib, that is, the transverse width of the rib 41 gradually decreases from the bottom wall to the top wall.

[0056] As an optional implementation, there are multiple ribs 41, and the multiple ribs 41 are distributed at intervals along the axial direction of the fluid inlet pipe joint 40. In this way, by providing multiple ribs 41, the sealing performance of the connection between the fluid inlet pipe joint 40 and the fluid delivery pipeline 10 can be further enhanced.

[0057] As an optional implementation, see [link to implementation details]. Figure 5 , Figure 6 , Figure 7 The fluid inlet pipe connector 40 is also provided with threaded ribs 43 in the axial direction, and the threaded ribs 43 are spaced apart from or adjacent to the ribs 41. In this way, the sealing performance of the connection between the fluid inlet pipe connector 40 and the fluid delivery pipeline 10 can be further ensured, and the friction between the fluid inlet pipe connector 40 and the fluid delivery pipeline 10 can be improved.

[0058] As an optional implementation, the rib 41 includes a first rib portion and a second rib portion connected to each other. The first rib portion is disposed on the fluid inlet pipe connector 40, and the second rib portion is sleeved on the second end of the fluid delivery pipe 10. Thus, the first rib portion being disposed on the fluid inlet pipe connector 40 and the second rib portion being sleeved on the second end of the fluid delivery pipe 10 further enhances the connection strength between the fluid inlet pipe connector 40 and the second end of the fluid delivery pipe 10, preventing the fluid inlet pipe connector 40 and the second end of the fluid delivery pipe 10 from detaching. The first rib portion and the second rib portion can be an integrally molded structure, that is, the first rib portion and the second rib portion can be obtained by injection molding.

[0059] As an optional implementation, see [link to implementation details]. Figure 4 The fluid inlet pipe connector 40 is further provided with a first reinforcing rib plate 42, and the first reinforcing rib plate 42 is located between the fluid inlet pipe connector 40 and the mounting plate 30. In this way, the first reinforcing rib plate 42 can enhance the strength of the fluid inlet pipe connector 40. The number of first reinforcing rib plates 42 is not limited here. There can be multiple first reinforcing rib plates 42, and the multiple first reinforcing rib plates 42 can be distributed at different positions between the fluid inlet pipe connector 40 and the mounting plate 30, thereby further enhancing the structural strength of the fluid inlet pipe connector 40.

[0060] As an optional implementation, the centerline of the fluid delivery pipeline 10 intersects the centerline of the nozzle 20, with the angle between the intersections ranging from 60 to 90 degrees. This allows the fluid to be ejected more smoothly from the nozzle 20 to the multimodal sensing device, thereby improving the decontamination efficiency of the multimodal sensing device.

[0061] This application also provides a vehicle, including a multimodal sensing device and a decontamination nozzle as described in the above embodiments. Since the vehicle provided in this application includes the decontamination nozzle as described in the above embodiments, it has the same beneficial technical effects as the above embodiments. The structure of the decontamination nozzle can be referred to the corresponding description in the above embodiments, and will not be repeated here.

[0062] The above are preferred embodiments of the present application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles disclosed in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
