Description

Door handle, detection device, detection system, vehicle door and vehicle

[0001] The present application claims priority to the Chinese patent application No. 202421594392.4, filed on July 5, 2024, and entitled "Door handle, detection device, detection system, vehicle door and vehicle", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of intelligent vehicles, and more particularly, to a door handle, a detection device, a detection system, a vehicle door and a vehicle. BACKGROUND

[0003] For a vehicle, the implementation of certain intelligent functions relies on the detection results of the environmental information around the vehicle. Compared with other sensors, millimeter wave radar has the characteristics of low cost, light weight, small blind area, high detection precision and stable operation in high and low temperature environments, and is widely used in environmental information detection.

[0004] Since the detection signal used by the millimeter wave radar is difficult to penetrate the sheet metal part, when arranging the millimeter wave radar, the sheet metal part is often avoided to be arranged on the propagation path of the detection signal. The components arranged at the front and rear of the vehicle include large-size non-sheet metal parts such as bumpers, and when it is necessary to detect the environmental information in front and rear of the vehicle by using the millimeter wave radar, the millimeter wave radar can be arranged on the vehicle.

[0005] However, the components arranged at the side of the vehicle are mainly composed of sheet metal parts, and when it is necessary to detect the environmental information at the side of the vehicle by using the millimeter wave radar, it is difficult to arrange the millimeter wave radar without affecting the vehicle styling.

[0006] SUMMARY

[0007] The present application provides a door handle, a detection device, a detection system, a vehicle door and a vehicle, by arranging the millimeter wave radar on the door handle, the environmental information at the side of the vehicle can be collected by the millimeter wave radar without affecting the external styling of the vehicle.

[0008] In a first aspect, a door handle (200) is provided. The door handle includes a first styling panel (210) and a bottom plate (220). The first styling panel (210) and the bottom plate (220) jointly form a first containing space, and the first containing space is used for containing a millimeter wave radar (100). The first styling panel (210) is made of a plastic material, and the first styling panel (210) includes a first styling area (211) facing the side of the vehicle, and the first styling area (211) is used for being arranged on the propagation path of the detection signal of the millimeter wave radar (100).

[0009] In the present application, the first styling panel is made of plastic material, and does not involve the problem that the detection signal of the millimeter wave radar cannot penetrate the first styling panel. By setting the millimeter wave radar in the accommodating space formed by the first styling panel and the bottom plate, the detection signal of the millimeter wave radar can propagate towards the side of the vehicle through the first styling area, and the millimeter wave radar can collect environmental information of the side of the vehicle without affecting the external styling of the vehicle.

[0010] Moreover, compared with other components, different vehicle models and different configurations of the same vehicle model are often provided with door handles. The arrangement of the millimeter wave radar on the door handle is applicable to different vehicle models and different configurations of the same vehicle model.

[0011] In some possible implementation manners, the first styling area (211) can also be used to cover the projection of the millimeter wave radar (100) on the first styling panel (210) along the vehicle transverse axis. That is, the projection of the millimeter wave radar (100) on the first styling panel (210) along the vehicle transverse axis is in the first styling area (211).

[0012] In actual scenarios, the first styling panel can include multiple styling areas including the first styling area. The curvature of the connecting part of adjacent styling areas is often large, and when the connecting part has a large curvature and is in the propagation path of the detection signal, it can interfere with the detection result of the millimeter wave radar. In the present application, by setting the projection of the millimeter wave radar on the first styling panel in the first styling area, the interference of the connecting part of adjacent styling areas on the detection result of the millimeter wave radar can be reduced.

[0013] In some possible implementation manners, the door handle (200) can further include a bracket (230) for fixing the millimeter wave radar (100). The bracket (230) can be arranged between the first styling panel (210) and the bottom plate (220), and the bracket (230) can be connected with the first styling panel (210).

[0014] In the present application, by arranging the bracket (230), the millimeter wave radar can be easily disassembled and replaced during the later maintenance process.

[0015] In some possible implementation manners, the bracket (230) can include a plate structure (232), and the plate structure (232) and the first styling panel (210) form a second accommodating space. The first accommodating space can contain the second accommodating space, and the second accommodating space can be used to accommodate the millimeter wave radar (100). The bracket (230) can be connected with the first styling panel (210) by welding, and can seal the second accommodating space.

[0016] In the present application, the use life of the millimeter wave radar is affected by the invasion of rain, dust and other sundries into the containing space by sealing the containing space where the millimeter wave radar is located. The second containing space can maintain a good sealing state under various working conditions by welding the bracket to the first molding panel.

[0017] In some possible implementation manners, the door handle (200) can further include a sealing member, which can include oppositely arranged first and second sealing surfaces. The first sealing surface can be attached to the first molding panel (210), and the second sealing surface can be attached to the bracket (230).

[0018] In the present application, even if the bracket and the first molding panel are connected by clamping, fasteners or other connection methods, the containing space where the millimeter wave radar is located can be made into a closed space by setting the sealing member, which is beneficial to balance the sealing effect of the containing space and the convenience of disassembling and replacing the millimeter wave radar during maintenance.

[0019] In some possible implementation manners, the millimeter wave radar (100) can include a first plane (101) for emitting a detection signal. The bracket (230) can be configured to: fix the millimeter wave radar (100) to make an included angle between the first plane (101) and a second plane (201) greater than or equal to a first threshold value. The first threshold value can be greater than or equal to 3 degrees, and the second plane can be a vertical plane perpendicular to the vehicle transverse axis direction.

[0020] Since the arrangement position of the door handle is often higher than the conventional arrangement height of the traditional millimeter wave radar, if the millimeter wave radar is vertically arranged, a large detection blind area will exist near the door. In the present application, by tilting the first plane of the millimeter wave radar for emitting a detection signal to the vertical direction, the detection blind area near the door can be reduced, which is beneficial to detecting obstacles near the road surface around the door.

[0021] In some possible implementation manners, the first molding region (211) can be a plane; or the first molding region (211) can be a curved surface, and the curvature of the curved surface can be less than or equal to a second threshold value.

[0022] Since the first molding region is on the propagation path of the detection signal, if the curvature of the curved surface is large in the case where the first molding region is a curved surface, the deflection of the detection signals emitted by the millimeter wave radar at different positions through the curved surface can be different, which can affect the detection result of the millimeter wave radar. In the present application, by setting the first molding region as a plane or a curved surface with a large curvature, the interference caused by improper setting of the curvature of the first molding region on the detection result of the millimeter wave radar can be reduced.

[0023] In some possible implementation manners, the first styling panel (210) can belong to the movable part or the fixed part of the door handle (200).

[0024] In a second aspect, 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) configured to emit a detection signal; and the bracket (230) is configured to: fix the millimeter wave radar (100) so that an included angle between the first plane (101) and a second plane (201) is greater than or equal to a first threshold value, the first threshold value being greater than or equal to 3 degrees, and the second plane being a vertical plane perpendicular to a lateral axis direction of a vehicle.

[0025] In some possible implementation manners, the bracket (230) can be configured to be arranged between the first styling panel (210) and the bottom plate (220) of the door handle (200), and can be connected with the first styling panel (210). The first styling panel (210) and the bottom plate (220) can be configured to enclose a first containing space; and the first containing space can be configured to contain the millimeter wave radar (100). The first styling panel (210) can be made of a plastic material; and the first styling panel (210) can include a first styling area (211) facing a lateral side of the vehicle, and the first styling area (211) can be configured to be arranged on a propagation path of the detection signal of the millimeter wave radar (100).

[0026] In some possible implementation manners, the bracket (230) can include a plate structure, and can be configured to enclose a second containing space with the first styling panel (210). The first containing space can include the second containing space, and the second containing space can be configured to contain the millimeter wave radar (100). The bracket (230) can also be configured to be connected with the first styling panel (210) by welding, and to seal the second containing space.

[0027] In some possible implementation manners, a sealing member can be arranged between the bracket (230) and the first styling panel (210). The sealing member can include oppositely arranged first and second sealing surfaces; the first sealing surface can be attached to the first styling panel (210), and the second sealing surface can be attached to the bracket (230).

[0028] In some possible implementation manners, a projection of the millimeter wave radar (100) on the first styling panel along the lateral axis direction of the vehicle can be located in the first styling area (211).

[0029] In some possible implementation manners, the first styling area (211) can be a plane; or the first styling area (211) can be a curved surface, and a curvature of the curved surface can be less than or equal to a second threshold value.

[0030] In some possible implementation manners, the first molding panel (210) can belong to the movable part or the fixed part of the door handle (200).

[0041] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0042] Exemplarily, FIG. 1 is a schematic diagram of a vehicle provided by an embodiment of the present application. As shown in FIG. 1, the vehicle 1 can include a front fender 11, a front door 12, a rear door 13, a rear fender 14, and a rocker 15. Some sheet metal parts can be provided with accessories (such as a trim 151, door handles 121, 131, etc.). The same type of components located on the left and right sides of the vehicle can be distinguished by a suffix. For example, the suffix "-1" can indicate that the component is on the left side of the vehicle; and the suffix "-2" can indicate that the component is on the right side of the vehicle. As shown in (b) of FIG. 1, the front door 12 of the vehicle 1 can include a left front door 12-1 and a right front door 12-2.

[0043] To achieve certain functions, it can be necessary to perceive the environmental information of the side of the vehicle (such as the areas A and B shown in (b) of FIG. 1). For example, in the case of a vehicle door anti-collision function, by detecting the environmental information of the side of the vehicle, it can be determined whether there is an obstacle on the opening path of the vehicle door; when there is an obstacle on the opening path of the vehicle door, one or more of the following methods can be used to reduce the risk of scratching when the vehicle door is opened: reminding the user, limiting the angle of opening of the vehicle door, limiting the opening speed of the vehicle door, limiting the opening of the vehicle door by the user, etc.

[0044] Compared with camera sensors, ultrasonic radars and millimeter wave radars have lower cost and power consumption, and have significant advantages in achieving the vehicle door anti-collision function. Moreover, compared with ultrasonic radars, millimeter wave radars have the advantages of light weight, small detection blind area, high detection accuracy, large effective detection range, and high stability in high and low temperature environments, etc. Therefore, millimeter wave radars can be used to detect the surrounding environment to achieve the above-mentioned vehicle door anti-collision function.

[0045] On the one hand, when millimeter wave radars are used to detect the environmental information of the side of the vehicle, in order to avoid deterioration of the appearance of the vehicle, the external appearance of the vehicle needs to shield the millimeter wave radars. However, the main parts of the components such as the front fender 11, the front door 12, the rear door 13, the rear fender 14, and the rocker 15 provided on the side of the vehicle are often composed of sheet metal parts. Since the detection signals used by the millimeter wave radars cannot penetrate the sheet metal parts, the sheet metal parts that shield the millimeter wave radars will inevitably be on the propagation path of the detection signals, affecting the detection results of the millimeter wave radars.

[0046] On the other hand, in order to ensure the normal operation of the millimeter wave radars, holes can be provided in the corresponding areas of the sheet metal parts to avoid the detection signals; however, the provision of these holes will affect the appearance of the vehicle.

[0047] Although in some embodiments, the threshold 15 can be provided with a plastic decorative piece 151. However, if the millimeter wave radar is shielded by the decorative piece 151, on the one hand, the external modeling surface of the decorative piece 151 tends to be provided with protrusions (or there are relatively large curvature surfaces), which will affect the detection results of the millimeter wave radar even if the detection signal can penetrate the decorative piece 151. On the other hand, the height of the decorative piece 151 is often much smaller than the millimeter wave radar, making it difficult to match the size of the millimeter wave radar with the decorative piece 151. Moreover, some / all configurations of certain vehicle models can not be provided with the decorative piece 151; that is, the decorative piece 151 is not applicable to all vehicles, resulting in poor universality of this arrangement.

[0048] When it is necessary to use the millimeter wave radar to detect the environmental information of the side of the vehicle, the above factors will make it difficult to arrange the millimeter wave radar on the vehicle.

[0049] In view of this, the embodiments of the present application provide a door handle, a detection device, a detection system, a vehicle door and a vehicle, by integrating the millimeter wave radar in the door handle, the environmental information of the side of the vehicle can be collected by the millimeter wave radar without affecting the external modeling of the vehicle.

[0050] Exemplarily, FIG. 2 is a structural schematic diagram of a detection system provided by an embodiment of the present application. In FIGS. 2-5, the directions x, y and z can represent the transverse axis direction, the longitudinal axis direction and the height direction of the vehicle, respectively.

[0051] As shown in FIG. 2, the detection system 400 can include a millimeter wave radar 100 and a door handle 200.

[0052] The door handle 200 can include a first modeling panel 210 and a bottom plate 220. The first modeling panel 210 and the bottom plate 220 can enclose a containing space, and the millimeter wave radar 100 can be arranged in the containing space. The first modeling panel 210 can include a first modeling area 211 facing the side of the vehicle; the first modeling panel 210 can also include other modeling areas, such as modeling areas 212, 213.

[0053] As shown in FIG. 2, the modeling areas on the first modeling panel 210 and the door panel can be used to form the external modeling surface of the vehicle; the first modeling panel 210 can shield the millimeter wave radar 100, and can avoid the millimeter wave radar 100 being exposed outside the external modeling surface of the vehicle. The first modeling panel 210 can also include non-modeling areas, such as the area blocked by the door panel in FIG. 2.

[0054] The first styling panel 210 can be made of plastic material to avoid interference of the detection result of the millimeter wave radar 100 by metal material. For example, in some embodiments, the main body part of the first styling panel 210 can be made of plastic material to avoid interference of the detection signal propagation process by metal material; outside the detection signal propagation path, the first styling panel 210 can contain metal components. For another example, in some embodiments, the external styling area of the first styling panel 210 can adopt electroplating, painting and other processes.

[0055] As shown in FIG. 2, the first styling area 211 can be on the propagation path of the detection signal of the millimeter wave radar 100. For example, the first styling area 211 can be a flat surface to avoid interference of the detection result of the millimeter wave radar by the sudden change of the styling.

[0056] In the embodiments of the present application, since the first styling panel 210 is made of plastic material, the problem that the detection signal of the millimeter wave radar 100 cannot penetrate the first styling panel 210 is avoided. By arranging the millimeter wave radar 100 in the accommodating space formed by the first styling panel 210 and the bottom plate 220, the detection signal of the millimeter wave radar can propagate towards the side of the vehicle through the first styling area, and the environmental information of the side of the vehicle can be collected by the millimeter wave radar without affecting the external styling of the vehicle.

[0057] Moreover, compared with other components (such as the trim 151), the vehicle door handle is often arranged in different vehicle models and different configurations of the same vehicle model. Arranging the millimeter wave radar on the vehicle door handle has good applicability for different vehicle models and different configurations of the same vehicle model.

[0058] In some embodiments, the first styling area 211 can be a curved surface; the curvature of the curved surface can be less than or equal to a certain curvature threshold. For example, the first styling area 211 is a smooth curved surface, and the radius of curvature on the curved surface can be greater than or equal to a threshold 1. The threshold 1 can be 1000 millimeters (mm), 1500 mm, 1800 mm; in some embodiments, the threshold 1 can also be determined according to the specific needs of the arrangement position of the millimeter wave radar 100. For another example, when the styling area 213 is also on the propagation path of the detection signal of the millimeter wave radar 100, the curvature of the styling area 213 and the radius of curvature of the connecting area between the styling areas 211 and 213 can also be greater than or equal to the threshold 1.

[0059] Since the first shaping area 211 is in the propagation path of the detection signal, in the case that the first shaping area 211 is a curved surface, if the curvature of the curved surface is large, the deflection of the detection signals emitted from different positions of the millimeter wave radar when passing through the curved surface can be different, which can affect the detection result of the millimeter wave radar. In the embodiment of the present application, by setting the first shaping area as a curved surface with large curvature, the interference of improper curvature setting on the detection result of the millimeter wave radar can be reduced.

[0060] The millimeter wave radar 100 can include a first plane 101 for emitting a detection signal. The millimeter wave radar 100 can also include a plane for receiving a reflected signal of the detection signal; the plane for receiving the reflected signal can be different from the first plane 101, or can also be the same plane as the first plane 101.

[0061] In some embodiments, the included angle between the first plane 101 and the vertical plane 201 (such as angle 1 in FIG. 2) can be greater than or equal to a certain angle threshold; the vertical plane 201 can be a vertical plane perpendicular to the vehicle transverse axis direction. For example, due to the relatively high arrangement position of the door handle, when it is necessary to detect obstacles near the ground, if the plane 101 is arranged in the vertical direction, a large detection blind area will exist near the door; as shown in FIG. 2, the first plane can be arranged downwardly inclined to reduce the detection blind area near the door. For example, the angle threshold can be 3 degrees. For example, the angle 1 can be 5 degrees, 7 degrees, 13 degrees, or 15 degrees. In some implementations, the specific value of the included angle can be determined according to the installation height of the door handle and the requirements for the detection area.

[0062] Since the arrangement position of the door handle 200 is often higher than the conventional arrangement height of the traditional millimeter wave radar, if the millimeter wave radar 100 is vertically arranged, a large detection blind area will exist on the door opening and closing path. In the embodiment of the present application, by arranging the millimeter wave radar 100 inclined to the vertical direction, it is beneficial to detect obstacles near the road surface around the door.

[0063] In some embodiments, the projection of the millimeter wave radar 100 on the first shaping panel 210 along the vehicle transverse axis direction can be within the first shaping area 211, as shown in FIG. 2.

[0064] In some embodiments, the projection of the millimeter wave radar 100 on the first shaping panel 210 along the normal direction of the first plane 101 can be within the first shaping area 211, as shown in FIG. 2.

[0065] The first styling panel can include other styling areas in addition to the first styling area 211, such as styling areas 212 and 213. The curvature of the connecting part of adjacent styling areas can be relatively large, and when the connecting part is in the propagation path of the detection signal, it will interfere with the detection results of the millimeter wave radar. In the embodiments of the present application, by setting the projection of the millimeter wave radar 100 on the first styling panel 210 within the first styling area 211, the interference of the connecting part of adjacent styling areas on the detection results of the millimeter wave radar can be avoided.

[0066] For example, in order to facilitate the installation of the millimeter wave radar 100, the detection system 400 can further include a bracket 230, and the millimeter wave radar 100 can be fixedly arranged on the bracket 230. For example, the millimeter wave radar 100 can be fixedly arranged on the bracket 230 by means of fastener connection, riveting, gluing, clamping, etc. For another example, when the millimeter wave radar 100 is fixedly arranged on the bracket 230, the included angle formed by the first plane 101 and the second plane 201 can meet the required angle arrangement requirement.

[0067] In some implementations, the bracket 230 can belong to the door handle 200. That is, the door handle 200 can further include the bracket 230 for fixedly arranging the millimeter wave radar 100.

[0068] In yet other implementations, since the bracket 230 is used to fixedly arrange the millimeter wave radar 100, when the two are produced by different manufacturers, there can be a problem that the consistency of tolerance control is poor, thereby affecting the position accuracy of the millimeter wave radar 100 on the door handle. In order to facilitate the management of parts, the detection system 400 can be composed of a detection device 300 and a door handle 200. The detection device 300 can include the millimeter wave radar 100 and the bracket 230, and the door handle 200 can include the first styling panel 210 and the bottom plate 220. That is, the bracket 230 can not belong to the door handle 200, but belong to the detection device 300.

[0069] For example, as shown in FIG. 3, the bracket 230 can include a support structure 231, and the millimeter wave radar 100 can be fixedly arranged on the support structure 231 by means of a bolt. The bracket 230 can further include a plate structure 242 connected with the support structure 231, and the plate structure 242 can be combined with the first styling element 210 to form an accommodation space for accommodating the millimeter wave radar 100.

[0070] The bracket 230 can be connected with the first styling panel 210 or the bottom plate 220. For example, the bracket 230 can be connected with the first styling panel 210 or the bottom plate 220 by means of fastener connection, riveting, clamping, etc.

[0071] In one embodiment, the bracket 230 and the first molding panel 210 are connected by welding, and the connection area between the two can be a welding area. For example, in order to reduce the welding area and improve the welding quality, the bracket 230 and the first molding panel 210 can be respectively provided with a concave structure and a convex structure that can match each other, as shown in (a) of FIG. 4; the concave structure and the convex structure can be connected by welding. In this case, the welding area between the bracket 230 and the first molding panel 210 can be formed by the part where the concave structure and the convex structure are connected.

[0072] In order to prevent rain, dust and the like from affecting the service life of the millimeter wave radar 100, the accommodation space where the millimeter wave radar 100 is located can be a sealed space.

[0073] In one embodiment, when the bracket 230 is connected to the first molding panel 210 by welding, the bracket 230 can seal the accommodation space where the millimeter wave radar 100 is located. For example, assuming that the bracket 230 has the structure shown in FIG. 3, the welding area between the bracket 230 and the first molding panel 210 can be as shown in (b) of FIG. 4; thus, the bracket 230 can seal the accommodation space where the millimeter wave radar is located.

[0074] In the embodiments of the present application, by sealing the accommodation space where the millimeter wave radar 100 is located, it can be avoided that rain, dust and the like enter the accommodation space and affect the service life of the millimeter wave radar 100. The bracket 230 with a plate structure is fixed to the first molding panel 210 by welding, so that the accommodation space can maintain good sealing effect when the vehicle is in a bumpy state.

[0075] In another embodiment, the bracket 230 can be fixed to the first molding panel by a bolt; a sealing element can be arranged between the first molding panel 210 and the bracket 230, and the sealing element can include two sealing surfaces arranged opposite to each other, one of which can be attached to the first molding panel 210, and the other of which can be attached to the bracket 230. For example, the cross section of the sealing element can be square, as shown in (a) of FIG. 5. For another example, the cross section of the sealing element can be circular or elliptical; in this case, the two curved surfaces of the circular or elliptical shape arranged opposite to each other can be attached to the first molding panel 210 and the bracket 230, respectively. For another example, the rear view of the sealing element can be as shown in (b) of FIG. 5.

[0076] In the embodiments of the present application, by arranging the sealing element, even if the bracket 230 and the first molding panel 210 are connected by clamping, fastening or the like, the accommodation space where the millimeter wave radar 100 is located can be a sealed space, which is conducive to taking into account the sealing effect of the accommodation space and the convenience of disassembly and replacement of the millimeter wave radar 100 during maintenance.

[0077] In FIGS. 2-5, the bracket 230 is an independent component; in some possible implementations, the bracket 230 can also be coupled to the first styling panel 210 and the bottom plate 220.

[0078] In some embodiments, the door handle 200 can include a movable part and / or a fixed part; the first styling panel 210 can belong to the movable part or the fixed part. The movable part and the fixed part of the door handle are exemplarily described below in connection with FIGS. 6 and 7.

[0079] Exemplarily, FIG. 6 shows several different forms of door handles.

[0080] In one embodiment, as shown in (a) of FIG. 6, the door handle A is an outward-pulling door handle; the door handle A can 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 can be fixedly arranged on the door; when a user uses the door handle A to open the door, the movable part A1 can be pulled in the direction 1, as shown in (a) of FIG. 6.
