DETAILED DESCRIPTION

[0037] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0039] The following combination Figures 1-9 A radar 10 and a vehicle 100 including the radar 10 according to an embodiment of the present application will be described in detail.

[0040] Reference Figure 1-Figure 2 、 Figure 7 As shown, the radar 10 according to an embodiment of the present application is applied to a vehicle 100 , and the radar 10 may include a housing 1 , a transceiver 2 , and a control device 40 .

[0041] The housing 1 has a housing cavity formed therein, and the transceiver 2 is disposed therein. The transceiver 2 is configured to transmit light to the external environment and receive light reflected from the external environment. The control device 40 is mounted on the housing 1, and the transceiver 2 is connected to the control device 40. The control device 40 is configured to transmit the light signal received by the transceiver 2 to the controller 20 of the vehicle 100. The controller 20 processes the light signal to generate image information of the external environment.

[0042] Housing 1 protects transceiver 2 from damage caused by squeezing, bumping, or other impacts. Transceiver 2 includes a transmitter module and a receiver module. The transmitter module transmits light to the outside world, while the receiver module receives light reflected from the outside world. The light emitted by transceiver 2 should be broadly defined, and may include, for example, lasers or microwaves.

[0043] After the light is emitted from the transmitting module, it will be reflected back by the physical object when it touches the physical object in the external environment, and the reflected light is received by the receiving module. The light signal received by the transceiver 2 is transmitted to the controller 20 of the vehicle 100 through the control device 40, and data processing is performed in the controller 20. The hardware equipment for data processing often generates a lot of heat. The radar 10 of the present application transfers the data processing to the controller 20 of the vehicle 100 (i.e., the body control end), so that the controller 20 serves as the hardware equipment for data processing, reducing the heat generated by the radar 10 itself. Therefore, there is no need to design too many heat dissipation structures on the shell 1, which reduces the weight of the shell 1 and saves the manufacturing cost of the shell 1, so that the performance of the radar 10 is further improved. At the same time, since heat dissipation structures such as heat dissipation fins and heat dissipation ribs are no longer added to the shell 1, the weight of the radar 10 is reduced and the manufacturing cost of the radar 10 is saved.

[0044] In some embodiments, when connecting the control device 40 to the controller 20 of the vehicle 100, a connecting wire can be used for connection, one end of the connecting wire is connected to the control device 40, and the other end of the connecting wire is connected to the controller 20 of the vehicle 100. Thus, the connecting wire can transmit signals, data, etc. in the control device 40 to the controller 20 of the vehicle 100.

[0045] In other embodiments, the transmission of signals, data, etc. between the control device 40 and the controller 20 may be wireless transmission.

[0046] In related art, the radar itself analyzes and processes the received light signals, causing significant internal heat generation. Therefore, it is necessary to design heat dissipation structures such as heat dissipation fins and heat dissipation ribs in the housing to dissipate heat from the radar. However, this increases the manufacturing cost and weight of the housing. According to the radar 10 of the embodiment of the present application, by moving the light signal processing process to the controller 20 of the vehicle 100, the heat generation of the radar 10 can be reduced. This eliminates the need for additional heat dissipation structures in the housing 1, thereby avoiding the increase in the manufacturing cost and weight of the housing 1, and thus the manufacturing cost and overall weight of the radar 10.

[0047] In some embodiments of the present application, reference is made to Figure 2-Figure 3 、 Figure 7 As shown, the control device 40 includes a first circuit board 4 and a connector 5. The first circuit board 4 is located within the accommodating cavity and is mounted on the housing 1. The transceiver 2 is connected to the first circuit board 4, and the connector 5 is connected to the first circuit board 4. The connector 5 is adapted to connect to the controller 20 of the vehicle 100. In other words, the transceiver 2 is connected to the connector 5 via the first circuit board 4, and the first circuit board 4 is connected to the controller 20 via the connector 5. The first circuit board 4 enables the vehicle to receive and transmit signals to the transceiver 2 and to control the transceiver 2.

[0048] In some embodiments of the present application, reference is made to Figure 1-Figure 2 、 Figure 7-Figure 8 As shown, the housing 1 is provided with a connection port 15, and the connector 5 is at least partially exposed from the connection port 15. When the connector 5 is connected to the controller 20 of the vehicle 100 via a connection line, the connection line can be connected to the connector 5 from the connection port 15.

[0049] In some embodiments, reference Figure 1-Figure 2 、 Figure 7-Figure 8 As shown, the connector 5 can be installed at the connection port 15, the outer peripheral surface of the connector 5 can contact the hole wall of the connection port 15, and the plug-in end of the connector 5 is exposed from the connection port 15, which facilitates the connection between the connector 5 and the connecting line.

[0050] In some embodiments, the connector 5 and the connection port 15 can be sealed by a sealing ring, thereby preventing moisture and dust from entering the interior of the housing 1 through the gap between the connector 5 and the connection port 15. For example, the sealing ring can be provided between the outer peripheral surface of the connector 5 and the hole wall of the connection port 15.

[0051] In some embodiments of the present application, reference is made to Figure 1-Figure 2 、 Figure 7-Figure 8 As shown, the connector 5 is mounted on the housing 1. In this way, the position of the connector 5 is fixed, the connector 5 is not easy to shake, and when the connecting line is connected to the connector 5, the operation is more convenient.

[0052] In some embodiments of the present application, reference is made to Figure 1-Figure 2 、 Figure 7-Figure 8 As shown, the housing 1 includes a first housing 11 and a second housing 12 , the transceiver 2 is mounted on the first housing 11 , the second housing 12 is connected to the first housing 11 , and the connector 5 is provided on the first housing 11 and / or the second housing 12 .

[0053] Specifically, the radar 10 transmits data to the vehicle control terminal through the connector 5. The plug end of the connector 5 can be set on the first shell 11. Figure 8 The plug end of the connector 5 may also be provided on the second housing 12, as shown Figure 1-Figure 2 、 Figure 7 As shown, the plug end of the connector 5 can also be partially provided on the first housing 11 and the other part on the second housing 12. At the same time, a sealing ring is required at the female end (i.e., the connecting cable) that mates with the plug end of the connector 5 to seal the end face of the connector 5 to prevent moisture and dust from entering the interior of the radar 10 and affecting the performance of the radar 10.

[0054] By dividing the housing 1 into the first housing 11 and the second housing 12, the housing 1 is designed to be split, which facilitates the installation and removal of components in the accommodating cavity. At the same time, the split housing 1 is easier to process than the integrated design.

[0055] In some embodiments of the present application, the second shell 12 and the first shell 11 can be connected and fixed by fasteners. In the description of the present application, the fasteners can be bolts, clips, rivets, etc.

[0056] The radar 10 of the present application moves data processing into the controller 20 of the vehicle 100, reducing the heat generated by the radar 10 itself. This not only simplifies the design of the second housing 12 and reduces the heat dissipation design of the second housing 12, but also improves the performance of the radar 10.

[0057] In some embodiments of the present application, reference is made to Figure 2-Figure 3 、 Figure 7 As shown, the radar 10 further includes a reflector 3 disposed within the housing cavity. The reflector 3 has a reflective surface for reflecting at least a portion of the light emitted by the transceiver 2 toward the external environment. The light entering the external environment can be used to detect the surrounding scene. The light reflected from the scene in the external environment is received by the receiving module of the transceiver 2. The receiving module transmits the information (light signal, data, etc.) to the controller 20 of the vehicle 100 for processing via the control device 40. The controller 20 of the vehicle 100 can be connected to the central control screen of the vehicle 100 to display the surrounding scene on the central control screen.

[0058] In some embodiments, a portion of the light emitted by the transceiver 2 may be directly emitted to the external environment, and another portion may be reflected to the external environment via a reflective surface.

[0059] In other embodiments, all light emitted by the transceiver 2 is reflected by the reflective surface to the external environment.

[0060] In some embodiments of the present application, a window is provided on the housing 1, and the reflecting device 3 is used to reflect at least a portion of the light emitted by the transceiver 2 to the external environment through the window. The window provides a channel for light to enter and exit the housing 1.

[0061] In some embodiments of the present application, the reflective device 3 includes a reflective body and a driver. The reflective surface is located on the reflective body, and the driver is connected to the first circuit board 4. The driver is used to drive the reflective body to move to change the direction of the reflective surface. When the direction of the reflective surface changes, the reflective surface can reflect light in different directions, thereby facilitating the collection of scenes of the external environment from multiple directions. The first circuit board 4 can be used for the entire vehicle to receive and transmit signals to the reflective device 3, and the first circuit board 4 can be used to control the reflective device 3.

[0062] In some embodiments, the driving member may be a motor, a combination of a motor and a reducer, or a combination of a motor and a transmission mechanism. The transmission mechanism may be a gear transmission, a multi-link transmission, or the like.

[0063] In some embodiments, the driving member has an output shaft, and the reflective body is connected to the output shaft. When the output shaft rotates, the reflective body is driven to rotate, thereby changing the direction of the reflective surface.

[0064] In some embodiments of the present application, reference is made to Figure 2 As shown, the radar 10 further includes a second circuit board 6, through which the reflector 3 and the first circuit board 4 are connected. Specifically, the second circuit board 6 is used to connect the first circuit board 4 and the reflector 3. The reflector 3 is connected to the second circuit board 6. A male connector is provided on the second circuit board 6, and a female connector is provided on the back side of the first circuit board 4. The female connector corresponds to the male connector. The connection between the female connector and the male connector creates an effective electrical connection between the first circuit board 4 and the second circuit board 6, thereby ensuring a stable connection between the reflector 3 and the first circuit board 4.

[0065] In some embodiments of the present application, reference is made to Figure 2 、 Figure 4As shown, a second circuit board mounting position 16 is provided in the housing 1, and the second circuit board 6 is suitable for being mounted in the second circuit board mounting position 16. The second circuit board mounting position 16 can be a mounting plate, which is used to support the mounting plate from bottom to top, and has mounting holes provided in the mounting plate, and the second circuit board 6 is fastened to the mounting holes by fasteners.

[0066] In some embodiments of the present application, reference is made to Figure 7 As shown, the radar 10 also includes a flat cable 7, which connects the reflector 3 to the first circuit board 4. This eliminates the need for the second circuit board 6 and electrical connectors, simplifying the production process and reducing the production cost of the radar 10. The flat cable 7 can be a flexible flat cable that can be bent freely, allowing for greater flexibility in the angle at which the reflector 3 and the first circuit board 4 are arranged.

[0067] In some embodiments of the present application, reference is made to Figure 2-Figure 4 As shown, the housing 1 is provided with a first mounting surface 13 and a second mounting surface 14. The transceiver 2 is mounted on the first mounting surface 13, and the reflector 3 is mounted on the second mounting surface 14. The first mounting surface 13 and the second mounting surface 14 are different planes. By mounting the transceiver 2 and the reflector 3 on different mounting surfaces, the installation operations of the transceiver 2 and the reflector 3 do not interfere with each other.

[0068] Reference Figure 4 As shown, a first mounting hole is provided on the first mounting surface 13, and the transceiver 2 can be installed in the first mounting hole by a fastener. A second mounting hole is provided on the second mounting surface 14, and the reflector 3 can be installed in the second mounting hole by a fastener.

[0069] In some embodiments of the present application, the first mounting surface 13 and the second mounting surface 14 form an angle greater than 0° and less than 180°. As a result, a certain offset angle exists between the transceiver 2 and the reflector 3, which can improve the light utilization efficiency of the transmitting module and the receiving module of the transceiver 2. For example, the light emitting end of the transmitting module can be positioned at a suitable angle with the reflecting surface of the reflector 3, and the light receiving end of the receiving module can be positioned at a suitable angle relative to the reflector 3. At the same time, the longitudinal field of view of the radar 10 can be effectively increased, and the longitudinal blind spot of the radar 10 can be reduced, thereby effectively improving the performance of the radar 10.

[0070] In some embodiments of the present application, the first mounting surface 13 and the second mounting surface 14 have an included angle that is no greater than 5°. For example, the included angle may be 1°, 2°, 3°, 4°, 5°, or other angle values ​​no greater than 5°.

[0071] In some embodiments of the present application, the direction of the light emitted by the transceiver 2 is parallel to the first mounting surface 13 .

[0072] In some embodiments of the present application, reference is made to Figure 3 As shown, the transceiver 2 and the reflector 3 are both located on the same side of the first circuit board 4 in the first direction, and the reflector 3 and the transceiver 2 are arranged apart in the second direction. The first direction and the second direction are different directions. Figure 3 In the example, the first direction is F1-F2, and the second direction is F3-F4. The transceiver 2 and the reflector 3 are both arranged on the F1 side of the first circuit board 4. The reflector 3 and the transceiver 2 are spaced apart in the F3-F4 direction. For example, the reflector 3 is located on the F4 side of the transceiver 2. This greatly improves the space utilization of the housing 1 and significantly reduces the external volume of the radar 10, making the radar 10 more lightweight.

[0073] In some embodiments of the present application, reference is made to Figure 1-Figure 3 、 Figure 7-Figure 8 As shown, the housing 1 includes a first housing 11 and a second housing 12. The transceiver 2 is mounted on the first housing 11, and the second housing 12 is connected to the first housing 11. The radar 10 also includes a sealing structure, which is provided at the connection between the second housing 12 and the first housing 11. The sealing structure is used to seal the gap between the second housing 12 and the first housing 11. The sealing structure can provide sealing, dustproof, and waterproof effects.

[0074] In some embodiments of the present application, one of the first shell 11 and the second shell 12 has a sealing groove 18, and the sealing structure is at least partially disposed in the sealing groove 18, and the sealing structure is also in contact with the other of the first shell 11 and the second shell 12. The sealing structure can be a colloid. When assembling the first shell 11 and the second shell 12, the colloid is solidified by applying glue in the sealing groove 18 to form a sealing gasket. The sealing gasket plays a good dustproof and waterproof role during the assembly process of the first shell 11 and the second shell 12, thereby ensuring the sealing of the radar 10 assembly. Figure 4 In the example of FIG, the first housing 11 has a sealing groove 18. In other embodiments, the sealing groove 18 may also be provided on the second housing 12.

[0075] exist Figure 3 In the example shown in FIG, the transceiver 2 and the reflector 3 are both arranged in the front area of ​​the first housing 11, and the first circuit board 4 is arranged in the rear area of ​​the first housing 11. This greatly improves the space utilization of the first housing 11 and greatly reduces the external volume of the radar 10, making the radar 10 more lightweight.

[0076] exist Figure 1-Figure 2 In the example of FIG, the radar 10 mainly includes a first housing 11, a second housing 12, a transceiver 2, a reflector 3, a first circuit board 4, and a second circuit board 6. Figure 3-Figure 4 As shown, the first housing 11 is used to mount and fix the reflector 3, the reflector 3, the first circuit board 4, and the second circuit board 6. The transceiver 2 is mainly used to transmit and receive light, and the first circuit board 4 is used for the entire vehicle to receive and transmit signals to the reflector 3 and the transceiver 2. The first circuit board 4 is used to control the reflector 3 and the transceiver 2. When assembling the radar 10, first fix the first shell 11 with a tooling, first install the reflector 3 on the first shell 11, then install the second circuit board 6 on the second circuit board mounting position 16, and then install the first circuit board 4 on the first shell 11. During the installation process, ensure that the female terminal of the connector of the first circuit board 4 and the male terminal of the connector on the second circuit board 6 are effectively electrically connected. Connect the reflector 3 to the second circuit board 6 through a flexible cable, and then install the transceiver 2 on the first shell 11. At the same time, the transceiver 2 is electrically connected to the first circuit board 4 through a flexible cable to ensure normal transmission of signals between the transceiver 2 and the first circuit board 4. Finally, install the second shell 12 with the first shell 11. Before installation, ensure that the sealing groove 18 of the first shell 11 has been glued and cured before installation.

[0077] Since both the reflecting device 3 and the transceiver device 2 need to be installed and fixed on the first shell 11, a first mounting surface 13 and a second mounting surface 14 are respectively designed on the first shell 11. The first mounting surface 13 serves as a positioning structure of the transceiver device 2 for positioning and installing the transceiver device 2, and the second mounting surface 14 serves as a positioning structure of the reflecting device 3 for positioning and installing the reflecting device 3.

[0078] Reference Figure 3-Figure 4 As shown, a circuit board positioning column 17 is provided in the first shell 11 , and a positioning hole is provided on the first circuit board 4 . The circuit board positioning column 17 passes through the positioning hole, thereby achieving positioning of the first circuit board 4 in the first shell 11 .

[0079] Specifically, the number of the circuit board positioning posts 17 can be one or more.

[0080] Reference Figure 4 The first shell 11 structure, Figure 5-Figure 6 As shown in the structure of the second shell 12 in the figure, the first shell 11 is designed as a complete structure with a cavity, and the second shell 12 is also designed as a complete structure with a cavity. The first shell 11 and the second shell 12 are not designed with redundant heat dissipation structures, such as import blocks, heat dissipation fins, heat dissipation ribs, etc. This not only beautifies the appearance of the radar 10, but also reduces the weight of the radar 10.

[0081] Reference Figure 9As shown, a vehicle 100 according to another embodiment of the present application includes a controller 20 and the radar 10 of the above embodiment, and a control device 40 is connected to the controller 20 .

[0082] According to the vehicle 100 of the embodiment of the present application, the heat generated by the radar 10 can be reduced by moving the processing process of the light signal to the controller 20 of the vehicle 100. In this way, there is no need to add a heat dissipation structure to the shell 1, which will not increase the manufacturing cost and weight of the shell 1, and thus the manufacturing cost and overall weight of the radar 10 will not be increased.

[0083] In some embodiments of the present application, vehicle 100 further includes a central control screen connected to controller 20 for displaying image information. Reflecting device 3 is configured to reflect light emitted by transceiver 2, thereby reflecting the light through a window in housing 1 for detecting the surrounding scene. The receiving module of transceiver 2 transmits the information via control device 40 to controller 20 of vehicle 100 for processing, thereby displaying the surrounding scene on the central control screen.

[0084] Specifically, the transceiver 2 includes a transmitting module and a receiving module. The transmitting module has a light transmitting end, and the receiving module has a light receiving end. The light emitted by the light transmitting end is reflected through the reflecting device 3. After the reflected light touches the physical object in the external environment, it is reflected back by the physical object. The light receiving end on the transceiver 2 receives the light reflected back by the physical object.
