Description

Technical Field

[0001] This application relates to the field of intelligent vehicles, and more specifically, to a door handle, a detection device, a detection system, a door, and a vehicle. Background Technology

[0002] For vehicles, the realization of certain intelligent functions depends on the detection results of environmental information around the vehicle. Compared with other sensors, millimeter-wave radar has the advantages of low cost, light weight, small detection blind zone, high detection accuracy, and stable operation in high and low temperature environments, and is widely used in environmental information detection.

[0003] Because the detection signals used by millimeter-wave radar are difficult to penetrate sheet metal parts, sheet metal parts are often avoided in the propagation path of the detection signals when installing millimeter-wave radar. Components located at the front and rear of a vehicle include large non-sheet metal parts such as bumpers. When it is necessary to use millimeter-wave radar to detect environmental information in front of and behind the vehicle, it is easy to install millimeter-wave radar on the vehicle.

[0004] However, the components located on the side of the vehicle are mainly made of sheet metal. When it is necessary to use millimeter-wave radar to detect environmental information on the side of the vehicle, it is difficult to arrange the millimeter-wave radar without affecting the vehicle's shape. Summary of the Invention

[0005] This application provides a door handle, a detection device, a detection system, a door, and a vehicle. By installing millimeter-wave radar in the door handle, it is possible to collect environmental information from the side of the vehicle without affecting the vehicle's external appearance.

[0006] In a first aspect, a door handle (200) is provided. The door handle includes a first styling panel (210) and a base plate (220). The first styling panel (210) and the base plate (220) together form a first receiving space for accommodating a millimeter-wave radar (100). The first styling panel (210) is made of plastic and includes a first styling area (211) facing the side of the vehicle, the first styling area (211) being positioned in the propagation path of the detection signal of the millimeter-wave radar (100).

[0007] In this application, since the first styling panel is made of plastic, the issue of the millimeter-wave radar's detection signal being unable to penetrate the first styling panel is not addressed. By placing the millimeter-wave radar within the enclosure formed by the first styling panel and the base plate, the detection signal of the millimeter-wave radar can penetrate the first styling area and propagate towards the side of the vehicle. This allows for the collection of environmental information from the side of the vehicle using millimeter-wave radar without affecting the vehicle's external styling.

[0008] Moreover, compared to other components, different car models and different configurations of the same car model often have door handles. The arrangement of placing millimeter-wave radar in the door handle has good applicability to different car models and different configurations of the same car model.

[0009] In some possible implementations, the first styling area (211) can also be used to cover the projection of the millimeter-wave radar (100) onto the first styling panel (210) along the vehicle's transverse axis. That is, the projection of the millimeter-wave radar (100) onto the first styling panel (210) along the vehicle's transverse axis is located within the first styling area (211).

[0010] In real-world scenarios, the first design panel may include multiple design regions, including the first design area. The curvature of the connecting portions between adjacent design regions is often significant. When these connecting portions have large curvature and are located within the propagation path of the detection signal, they may interfere with the detection results of the millimeter-wave radar. In this application, by placing the projection of the millimeter-wave radar onto the first design panel within the first design area, the interference caused by the connecting portions of adjacent design regions to the millimeter-wave radar's detection results can be reduced.

[0011] In some possible implementations, the door handle (200) may also include a bracket (230) for securing the millimeter-wave radar (100). The bracket (230) may be disposed between the first styling panel (210) and the base plate (220), and the bracket (230) may be connected to the first styling panel (210).

[0012] In this application, by setting up bracket 230, it is beneficial to disassemble and replace millimeter-wave radar during later maintenance.

[0013] In some possible implementations, the bracket (230) may include a plate-like structure (232) and together with the first shaped panel (210) form a second receiving space. The first receiving space may contain the second receiving space, which may be used to accommodate the millimeter-wave radar (100). The bracket (230) may be connected to the first shaped panel (210) by welding and may seal the second receiving space.

[0014] In this application, by sealing the housing space of the millimeter-wave radar, it is possible to prevent rainwater, dust, and other debris from entering the housing space and affecting the service life of the millimeter-wave radar. The bracket is fixed to the first shaped panel by welding, ensuring that the second housing space maintains a good seal under various operating conditions.

[0015] In some possible implementations, the door handle (200) may also include a seal, which may include a first sealing surface and a second sealing surface disposed opposite to each other. The first sealing surface may fit against the first styling panel (210), and the second sealing surface may fit against the bracket (230).

[0016] In this application, by setting a sealing element, even when the bracket and the first shaped panel are connected by means of snap-fit ​​or fastener connection, the housing space where the millimeter-wave radar is located can be made into a sealed space, which is beneficial to both the sealing effect of the housing space and the convenience of disassembling and replacing the millimeter-wave radar during maintenance.

[0017] In some possible implementations, the millimeter-wave radar (100) may include a first plane (101) for transmitting detection signals. A bracket (230) may be used to fix the millimeter-wave radar (100) such that the angle between the first plane (101) and the second plane (201) is greater than or equal to a first threshold. The first threshold may be greater than or equal to 3 degrees, and the second plane may be a vertical plane perpendicular to the vehicle's transverse axis.

[0018] Since door handles are often positioned higher than the conventional height of millimeter-wave radar, vertically mounting the radar would result in a significant blind spot near the door. This application addresses this by tilting the first plane of the millimeter-wave radar, which transmits detection signals, vertically, thus reducing the blind spot near the door and improving the detection of obstacles near the road surface around the door.

[0019] In some possible implementations, the first shaping region (211) can be a plane; or the first shaping region (211) can be a curved surface, the curvature of which can be less than or equal to the second threshold.

[0020] Since the first shaped area is located on the propagation path of the detection signal, if the curvature of the first shaped area is large, the deflection of detection signals emitted from different positions of the millimeter-wave radar as they pass through the surface may vary, affecting the detection results of the millimeter-wave radar. In this application, by setting the first shaped area as a plane or a surface with a large curvature, the interference caused to the detection results of the millimeter-wave radar due to improper curvature setting of the first shaped area can be reduced.

[0021] In some possible implementations, the first styling panel (210) may be part of the movable or fixed part of the door handle (200).

[0022] Secondly, a detection device (300) is provided. The detection device (300) includes a millimeter-wave radar (100) and a bracket (230). The millimeter-wave radar (100) includes a first plane (101) for transmitting detection signals; the bracket (230) is used to fix the millimeter-wave radar (100) such that the angle between the first plane (101) and the second plane (201) is greater than or equal to a first threshold, the first threshold being greater than or equal to 3 degrees, and the second plane being a vertical plane perpendicular to the transverse axis of the vehicle.

[0023] In some possible implementations, the bracket (230) can be disposed between the first styling panel (210) and the base plate (220) of the door handle (200), and can be connected to the first styling panel (210). The first styling panel (210) and the base plate (220) can be used to enclose and form a first receiving space; the first receiving space can be used to accommodate the millimeter-wave radar (100). The first styling panel (210) can be made of plastic; the first styling panel (210) can include a first styling area (211) facing the side of the vehicle, and the first styling area (211) can be disposed on the propagation path of the detection signal of the millimeter-wave radar (100).

[0024] In some possible implementations, the bracket (230) may include a plate-like structure and may be used to enclose a second receiving space with the first shaped panel (210). The first receiving space may contain the second receiving space, which may be used to accommodate the millimeter-wave radar (100). The bracket (230) may also be used to connect to the first shaped panel (210) by welding and to seal the second receiving space.

[0025] In some possible implementations, a seal may be provided between the bracket (230) and the first shaped panel (210). The seal may include a first sealing surface and a second sealing surface disposed opposite to each other; the first sealing surface may fit against the first shaped panel (210), and the second sealing surface may fit against the bracket (230).

[0026] In some possible implementations, the projection of the millimeter-wave radar (100) onto the first styling panel along the vehicle's transverse axis can be located within the first styling area (211).

[0027] In some possible implementations, the first shaping region (211) can be a plane; or the first shaping region (211) can be a curved surface, the curvature of which can be less than or equal to the second threshold.

[0028] In some possible implementations, the first styling panel (210) may be part of the movable or fixed part of the door handle (200).

[0029] Thirdly, a detection system is provided. This detection system may include a millimeter-wave radar and the door handle described in the first aspect and any possible implementation thereof; or, the detection system may include the detection device described in the second aspect and the door handle described in the first aspect and any possible implementation thereof.

[0030] Fourthly, a vehicle door is provided. This vehicle door may include the door handle described in the first aspect and any possible implementation thereof, or it may include the detection device described in the second aspect and any possible implementation thereof, or it may include the detection system described in the third aspect and any possible implementation thereof.

[0031] Fifthly, a vehicle is provided. The vehicle may include the door handle described in the first aspect and any possible implementation thereof, or may include the detection device described in the second aspect and any possible implementation thereof, or may include the detection system described in the third aspect and any possible implementation thereof, or may include the door described in the fourth aspect and any possible implementation thereof.

[0037] Figure 6 These are schematic diagrams of several different types of car door handles provided in the embodiments of this application;

[0038] Figure 7 This is a schematic diagram of several different opening methods of concealed door handles provided in the embodiments of this application. Detailed Implementation

[0039] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0040] For example, Figure 1This is a schematic diagram of a vehicle provided in an embodiment of this application. (As shown...) Figure 1 As shown, vehicle 1 may include a front fender 11, a front door 12, a rear door 13, a rear fender 14, and a door sill 15. Some sheet metal parts may have accessories (e.g., trim pieces 151, door handles 121, 131, etc.). Similar parts located on the left and right sides of the vehicle can be distinguished by suffixes. For example, the suffix "-1" indicates that the part is on the left side of the vehicle; the suffix "-2" indicates that the part is on the right side of the vehicle. Figure 1 As shown in (b), the front door 12 of vehicle 1 may include a left front door 12-1 and a right front door 12-2.

[0041] To achieve certain functions, it may be necessary to sense the sides of the vehicle (e.g., ...). Figure 1 The environmental information of areas A and B shown in (b) is illustrated. Taking the door collision avoidance function as an example, by detecting the environmental information on the side of the vehicle, it is possible to determine whether there are obstacles in the opening path of the door. When there are obstacles in the opening path of the door, the risk of the door scraping when opening can be reduced by one or more of the following methods: reminding the user, limiting the opening angle of the door, limiting the opening speed of the door, and limiting the user's opening of the door.

[0042] Compared to camera sensors, ultrasonic radar and millimeter-wave radar have lower costs and power consumption, offering significant advantages for implementing door collision avoidance functions. Furthermore, compared to ultrasonic radar, millimeter-wave radar offers advantages such as lighter weight, smaller blind spots, higher detection accuracy, larger effective detection range, and greater stability in high and low temperature environments. Millimeter-wave radar can be used to detect the surrounding environment to achieve the aforementioned door collision avoidance functions.

[0043] On the one hand, when using millimeter-wave radar to detect environmental information on the sides of a vehicle, the vehicle's external surfaces need to shield the radar to avoid deteriorating the vehicle's design. However, the main bodies of components located on the sides of the vehicle, such as the front fender 11, front door 12, rear door 13, rear fender 14, and sill 15, are often made of sheet metal. Since the detection signals used by millimeter-wave radar cannot penetrate sheet metal, the sheet metal components that shield the radar will inevitably be in the path of the detection signal, affecting the detection results.

[0044] On the other hand, to ensure the normal operation of millimeter-wave radar, holes can be set in the corresponding areas of sheet metal parts to avoid detection signals; however, the setting of these holes will affect the shape of the vehicle.

[0045] While in some embodiments, the sill 15 may be provided with a plastic decorative element 151, if the millimeter-wave radar is obscured by the decorative element 151, firstly, the outer surface of the decorative element 151 often has protrusions (or a curved surface with a large curvature), and even if the detection signal can penetrate the decorative element 151, these protrusions will affect the detection results of the millimeter-wave radar. Secondly, the height of the decorative element 151 is often much smaller than that of the millimeter-wave radar, making it difficult to match the size of the millimeter-wave radar with the decorative element 151. Moreover, some vehicle models may not have the decorative element 151 in some or all configurations; that is, the decorative element 151 is not suitable for all vehicles, resulting in poor versatility of this arrangement.

[0046] When it is necessary to use millimeter-wave radar to detect environmental information on the side of a vehicle, the above factors will make it difficult to deploy millimeter-wave radar on the vehicle.

[0047] In view of this, embodiments of this application provide a door handle, a detection device, a detection system, a door, and a vehicle. By integrating millimeter-wave radar into the door handle, environmental information on the side of the vehicle can be collected by millimeter-wave radar without affecting the external shape of the vehicle.

[0048] For example, Figure 2 This is a schematic diagram of the structure of a detection system provided in an embodiment of this application. Figures 2 to 5 In this context, the directions x, y, and z can represent the vehicle's lateral axis, longitudinal axis, and height, respectively.

[0049] like Figure 2 As shown, the detection system 400 may include a millimeter-wave radar 100 and a door handle 200.

[0050] The door handle 200 may include a first styling panel 210 and a base plate 220. The first styling panel 210 and the base plate 220 may be combined to form an accommodating space in which the millimeter-wave radar 100 may be disposed. The first styling panel 210 may include a first styling area 211 facing the side of the vehicle; the first styling panel 210 may also include other styling areas, such as styling areas 212 and 213.

[0051] like Figure 2 As shown, the styling area on the first styling panel 210 and the door sheet metal can be used to form the exterior styling surface of the vehicle; the first styling panel 210 can shield the millimeter-wave radar 100, preventing the millimeter-wave radar 100 from being exposed outside the vehicle's exterior styling surface. The first styling panel 210 may also include non-styling areas, such as... Figure 2 The area in the middle that is obscured by the sheet metal of the car door.

[0052] The first shaped panel 210 can be made of plastic to avoid interference from metal materials on the detection results of the millimeter-wave radar 100. For example, in some implementations, the main body of the first shaped panel 210 can be made of plastic to avoid interference from metal materials on the propagation of the detection signal; outside the detection signal propagation path, the first shaped panel 210 can include metal components. Furthermore, in some implementations, the outer shaped area of ​​the first shaped panel 210 can be treated with electroplating, coating, or other processes.

[0053] like Figure 2 As shown, the first shape region 211 can be located in the propagation path of the detection signal of the millimeter-wave radar 100. For example, the first shape region 211 can be planar to avoid abrupt changes in shape from interfering with the detection results of the millimeter-wave radar.

[0054] In this embodiment, since the first styling panel 210 is made of plastic, the problem of the millimeter-wave radar 100's detection signal being unable to penetrate the first styling panel 210 is not addressed. By placing the millimeter-wave radar 100 within the enclosure formed by the first styling panel 210 and the base plate 220, the millimeter-wave radar's detection signal can penetrate the first styling area and propagate towards the side of the vehicle. This allows for the collection of environmental information from the side of the vehicle using millimeter-wave radar without affecting the vehicle's external styling.

[0055] Moreover, compared to other components (such as trim piece 151), different car models and different configurations of the same model often have door handles. The arrangement of placing millimeter-wave radar in the door handle has good applicability to different car models and different configurations of the same model.

[0056] In some embodiments, the first shaping region 211 can be a curved surface; the curvature of the surface can be less than or equal to a certain curvature threshold. For example, the first shaping region 211 is a smooth curved surface, and the radius of curvature on the surface can be greater than or equal to the threshold 1. The threshold 1 can be 1000 mm, 1500 mm, or 1800 mm; in some embodiments, the threshold 1 can also be determined according to the specific requirements of the millimeter-wave radar 100 for its placement. For another example, when the shaping region 213 is also on the propagation path of the detection signal of the millimeter-wave radar 100, the curvature of the shaping region 213 and the radius of curvature of the connecting region between the shaping regions 211 and 213 can also be greater than or equal to the threshold 1.

[0057] Since the first shaped region 211 is located on the propagation path of the detection signal, if the curvature of the surface is large when the first shaped region 211 is curved, the deflection of the detection signal emitted from different positions of the millimeter-wave radar may vary when passing through the surface, thus affecting the detection results of the millimeter-wave radar. In this embodiment, by setting the first shaped region as a surface with a large curvature, the interference caused by improper curvature setting on the detection results of the millimeter-wave radar can be reduced.

[0058] The millimeter-wave radar 100 may include a first plane 101 for transmitting detection signals. The millimeter-wave radar 100 may also include a plane for receiving reflected signals of the detection signals; the plane for receiving reflected signals may be different from the first plane 101, or it may be the same plane as the first plane 101.

[0059] In some embodiments, the included angle between the first plane 101 and the vertical plane 201 (e.g.) Figure 2 Angle 1) in the figure can be greater than or equal to a certain angle threshold; vertical plane 201 can be a vertical plane perpendicular to the vehicle's transverse axis. For example, because the door handle is positioned relatively high, when it is necessary to detect obstacles near the ground, arranging plane 101 vertically will result in a large detection blind spot in the area near the door; such as Figure 2 As shown, the first plane can be tilted downwards to reduce the detection blind spot near the car door. For example, the angle threshold can be 3 degrees. Alternatively, the angle 1 can be 5 degrees, 7 degrees, 13 degrees, or 15 degrees. In some implementations, the specific value of this angle can be determined based on the installation height of the door handle and the requirements for the detection area.

[0060] Since the door handle 200 is often positioned higher than the conventional height of millimeter-wave radar, a vertically mounted millimeter-wave radar 100 would result in a significant blind spot along the door opening and closing path. In this embodiment, tilting the millimeter-wave radar 100 vertically facilitates the detection of obstacles near the road surface around the door.

[0061] In some embodiments, the projection of the millimeter-wave radar 100 onto the first styling panel 210 along the vehicle's transverse axis can be located within the first styling area 211, such as... Figure 2 As shown.

[0062] In some other embodiments, the projection of the millimeter-wave radar 100 onto the first shaped panel 210 along the normal direction of the first plane 101 can be located within the first shaped region 211, such as... Figure 2 As shown.

[0063] The first design panel may include other design areas besides the first design area 211, such as design areas 212 and 213. The curvature of the connecting portion between adjacent design areas may be relatively large, which will interfere with the detection results of the millimeter-wave radar when the connecting portion is in the propagation path of the detection signal. In this embodiment, by setting the projection of the millimeter-wave radar 100 on the first design panel 210 within the first design area 211, the interference of the connecting portion between adjacent design areas with the detection results of the millimeter-wave radar can be avoided.

[0064] For example, to facilitate the installation of the millimeter-wave radar 100, the detection system 400 may further include a bracket 230, on which the millimeter-wave radar 100 can be fixedly mounted. For instance, the millimeter-wave radar 100 can be fixedly mounted to the bracket 230 by means of fastener connection, riveting, gluing, snap-fitting, etc. As another example, when the millimeter-wave radar 100 is fixedly mounted to the bracket 230, the angle formed by its first plane 101 and second plane 201 can meet the required angular arrangement requirements.

[0065] In some implementations, the bracket 230 may be part of the door handle 200. That is, the door handle 200 may also include the bracket 230 for fixing the millimeter-wave radar 100.

[0066] In some implementations, since the bracket 230 is used to fix the millimeter-wave radar 100, when the two are manufactured by different manufacturers, there is a tendency for poor consistency in tolerance control, which in turn affects the positional accuracy of the millimeter-wave radar 100 on the door handle. To facilitate component management, the detection system 400 can consist of a detection device 300 and a door handle 200. The detection device 300 may include the millimeter-wave radar 100 and the bracket 230, while the door handle 200 may include the first styling panel 210 and the base plate 220. That is, the bracket 230 may not be part of the door handle 200, but rather part of the detection device 300.

[0067] For example, such as Figure 3 As shown, the bracket 230 may include a support structure 231; the millimeter-wave radar 100 can be fixedly mounted on the support structure 231 by bolts. The bracket 230 may also include a plate structure 242 connected to the support structure 231, and the plate structure 242 and the first shaping element 210 can be enclosed to form a receiving space for accommodating the millimeter-wave radar 100.

[0068] The bracket 230 can be connected to the first shaped panel 210 or the base plate 220. For example, the bracket 230 can be connected to the first shaped panel 210 or the base plate 100 by means of fastener connection, riveting, snap-fit, etc.

[0069] In one embodiment, the bracket 230 and the first shaped panel 210 are connected to each other by welding, and the area where they are connected can be called the welding area. For example, to reduce the welding area and improve the welding quality, the bracket 230 and the first shaped panel 210 can be respectively provided with a concave structure and a convex structure that can match each other, such as... Figure 4 As shown in (a), the concave structure and the convex structure can be connected to each other by welding. In this case, the welding area between the support 230 and the first shaped panel 210 can be formed by the part where the concave structure and the convex structure are connected to each other.

[0070] To prevent rainwater, dust, and other factors from affecting the service life of the millimeter-wave radar 100, the space in which the millimeter-wave radar 100 is housed can be a sealed space.

[0071] In one embodiment, when the bracket 230 is connected to the first shaped panel 210 by welding, the bracket 230 can seal the housing space where the millimeter-wave radar 100 is located. For example, assuming the bracket 230 is connected by welding... Figure 3 As shown in the structure, the welding area between the bracket 230 and the first shaped panel 210 can be as follows: Figure 4 As shown in (b) in the diagram; thus, the bracket 230 can seal the containment space where the millimeter-wave radar is located.

[0072] In this embodiment, by sealing the housing space where the millimeter-wave radar 100 is located, rainwater, dust, and other debris can be prevented from entering the housing space and affecting the service life of the millimeter-wave radar 100. The bracket 230 with a plate-like structure is fixed to the first shaped panel 210 by welding, so that the housing space can maintain a good sealing effect even when the vehicle is in a bumpy state.

[0073] In another embodiment, bolts can be used to fix the bracket 230 to the first shaped panel; a sealing element can be provided between the first shaped panel 210 and the bracket 230. This sealing element may include two opposing sealing surfaces, one of which can fit against the first shaped panel 210, and the other sealing surface can fit against the bracket 230. For example, the cross-section of the sealing element can be square, such as... Figure 5 As shown in (a) above. For example, the cross-section of the seal can be circular or elliptical; in this case, the two opposing curved surfaces of the circle or ellipse can respectively fit against the first shaped panel 210 and the bracket 230. For example, the rear view of the seal can be as shown below. Figure 5 As shown in (b) of the diagram.

[0074] In this embodiment, by setting a sealing element, even when the bracket 230 and the first shaped panel 210 are connected by means of snap-fit ​​or fastener connection, the housing space where the millimeter-wave radar 100 is located can be made into a sealed space, which is beneficial to balance the sealing effect of the housing space and the convenience of disassembly and replacement of the millimeter-wave radar 100 during maintenance.

[0075] exist Figures 2 to 5 In this context, the bracket 230 is an independent component; in some possible implementations, the bracket 230 may also be coupled to the first shaped panel 210 and the base plate 220.

[0076] In some embodiments, the door handle 200 may include a movable portion and / or a fixed portion; the first styling panel 210 may be either a movable portion or a fixed portion. The following description... Figure 6 and Figure 7 The movable and fixed parts of the door handle are described by way of example.

[0077] For example, Figure 6 Several different types of door handles are shown.

[0078] In one embodiment, such as Figure 6 As shown in (a), the door handle A is an outward-pulling door handle; the door handle A may include a movable part A1 and a fixed part A2. For example, for the door handle A, the movable part A1 and the fixed part A2 may be fixedly installed on the door; when the user uses the door handle A to open the door, he / she can pull the movable part A1 in direction 1, such as... Figure 6 As shown in (a) above. The movable part A1 may include a shaping area 1, and the fixed part A2 may include a shaping area 2, as shown below. Figure 6 As shown in (a) in the figure.

[0079] For example, the millimeter-wave radar 100 can be disposed on one side of the movable part A1; in this case, the shaping area 1 can correspond to the first shaping area 211, and a certain shaping panel included in the movable part A1 can correspond to the first shaping panel 210. As another example, the millimeter-wave radar 100 can be disposed on one side of the fixed part A2; in this case, the shaping area 2 can correspond to the first shaping area 211, and a certain shaping panel included in the fixed part A2 can correspond to the first shaping panel 210.

[0080] In yet another embodiment, such as Figure 6 As shown in (b), the door handle B is a fixed door handle. For example, when a user opens the door using the door handle B, the relative positional relationship between the door handle B and the door sheet metal remains unchanged. The door handle B may include a styling area 3, which may correspond to the first styling area 211. For example, a millimeter-wave radar 100 may be located behind the left, middle, or right side portion of the styling area 3.

[0081] In yet another embodiment, such as Figure 6 As shown in (c), the door handle C is another type of fixed door handle. The door handle C may include styling areas 4 to 6 facing the side of the vehicle.
