Description

Technical Field

[0001] This application relates to the field of automotive electronics technology, and specifically relates to an in-vehicle antenna installation structure, an environmental perception device, and a vehicle. Background Art

[0002] Installing an antenna, especially a GNSS antenna, on a vehicle can provide accurate position, speed, and time information for the vehicle. This is crucial for autonomous vehicles to achieve functions such as path planning, lane keeping, obstacle avoidance, and automatic parking.

[0003] Currently, GNSS antennas are mainly installed inside the A and B pillars, in the water collection trough under the external windshield of the vehicle, on the rear windshield, inside the roof shark fin antenna, and on the mounting base of the rearview mirror.

[0004] However, the above installation positions of GNSS antennas all have the following problems to varying degrees. For example, installing the GNSS antenna inside the A and B pillars not only causes the antenna signal receiving surface to be unable to directly face the sky, but can only capture reflected signals, resulting in a weakening of the signal intensity and affecting the stability of signal reception; moreover, since there are airbags inside the A and B pillars, the GNSS antenna may be ejected at high speed when the airbag deploys, posing a safety risk of injuring people. When the GNSS antenna is installed in the water collection trough under the external windshield of the vehicle, the antenna in the GNSS antenna will age faster due to being directly exposed to the natural environment and experiencing sun and rain for a long time; moreover, since the wiring of the GNSS antenna is relatively complex, when the wiring setting for it to enter the vehicle is improper, rainwater may seep into the vehicle. When the GNSS antenna is installed on the rear windshield or inside the roof shark fin antenna, it will result in a relatively long length of the wire harness connecting the GNSS antenna to the vehicle electronic system, which not only causes a high cost but also causes a certain signal attenuation. When the GNSS antenna is installed on the mounting base of the rearview mirror, since the interior trim such as the protective cover, the rearview mirror, and its base need to be disassembled during antenna repair, the operation process is relatively cumbersome and complex. Summary of the Invention

[0005] In order to solve at least one of the above problems, according to one aspect of the present application, an in-vehicle antenna installation structure is provided.

[0006] The vehicle-mounted antenna installation structure includes a first bracket, and the first bracket is an installation bracket for the sensing unit of the environmental perception device; the antenna module is integrated on the first bracket, and the antenna module and the first bracket are arranged such that the antenna module does not receive a weakened signal due to being integrated on the first bracket. In this application, the non-weakening of the received signal of the antenna module means that the received signal of the antenna module is not weakened at all, or that the received signal of the antenna module is weakened very little (for example, when there is no metal interference within 50 mm around the horizontal direction of the antenna of the antenna module and there is no metal interference on the receiving surface of the antenna, the requirement of very little weakening of the received signal of the antenna module can be met), which can be ignored. By integrating the antenna module and the sensing unit capable of sensing the environment on the first bracket, when it is necessary to install the antenna module and the sensing unit on a vehicle, only the first bracket needs to be installed on the vehicle, for example, on the windshield, and the installation and disassembly are quick; moreover, since the antenna module and the sensing unit are integrated together, the length of the signal transmission wire harness between the antenna module and the sensing unit can be greatly reduced, reducing signal attenuation while reducing costs.

[0007] In some embodiments, the antenna module is integrated on the first bracket such that the antenna receiving surface of the antenna module has no signal obstruction. In this application, no signal obstruction means that the transmission of the signal is not obstructed at all, or that although there is an obstruction to the signal transmission, it can be ignored. Thus, the antenna module can receive a stronger signal.

[0008] In some embodiments, the first bracket includes a base and a first cover; wherein, the base is used for installing the sensing unit and is provided with a first receiving cavity for accommodating the antenna module, and the first receiving cavity communicates with the outside through a first opening; the first cover is detachably covered on the first opening. Thus, the problem that the antenna module is prone to aging due to being directly exposed to the natural environment can be avoided.

[0009] In some embodiments, the base and / or the first cover are made of materials that do not affect the signal transmission of the antenna module. In this application, "not affecting the signal transmission of the antenna module" means that it does not affect the signal transmission of the antenna module at all, or the influence on the signal transmission of the antenna module is so small that it can be ignored. Thus, while avoiding the direct exposure of the antenna module to the natural environment, it is possible to prevent the first cover and / or the base from causing signal attenuation of the received signal by the antenna module. Materials that do not affect the signal transmission of the antenna module can be non-conductive materials or materials with a small loss tangent value; on the one hand, the dielectric constant of non-conductive materials is generally low (between 2 and 4), and non-conductive materials can be plastics, for example, ABS, polycarbonate or polypropylene materials, and no conductive materials (carbon fiber, metal powder) or reinforcing materials (glass fiber) can be added to the plastics to prevent the signal from being reflected or absorbed by the base and / or the first cover before being transmitted to the antenna module; on the other hand, the smaller the value of the loss tangent, the smaller the energy loss during signal penetration, and the loss tangent value of ordinary plastics is usually small. For example, the loss tangent value of polypropylene is about 0.0003.

[0010] In some embodiments, the thickness of the base and / or the first cover is less than 3 mm. When the thickness of the base and the first cover is relatively thick, it will cause signal attenuation of the received signal by the antenna module. Setting the thickness of the base and / or the first cover to be less than 3 mm can avoid the direct exposure of the antenna module to the natural environment and prevent the first cover and / or the base from causing signal attenuation of the received signal by the antenna module.

[0011] In some embodiments, the first cover is detachably covered on the first opening, which is realized by integrally forming or machining a first fastening position on the first cover, and integrally forming or machining a first clamping position on the base that is adapted to the first fastening position. When the first fastening position is engaged with the first clamping position, the first cover is covered on the first opening. Thus, the quick detachable connection between the first cover and the base can be realized without using external tools.

[0012] In some embodiments, the base is further provided with a first channel that communicates the installation position of the sensing unit with the first accommodation cavity, and the first channel is used to accommodate the wire harness of the antenna module. Thus, the wire harness routing of the antenna module can be made non-exposed, avoiding the direct exposure of the wire harness to the natural environment, slowing down the aging speed of the wire harness, and improving the aesthetic appearance of the vehicle.

[0013] In some embodiments, the first channel communicates with the outside through a second opening; the first bracket further includes a second cover, and the second cover is detachably covered on the second opening. Thus, during use, the aesthetic appearance of the vehicle-mounted antenna installation structure can be maintained through the second cover, avoiding the exposure of the wire harness; the second cover can also be opened to facilitate adjusting the wire harness routing or maintaining the wire harness.

[0014] In some embodiments, the second cover is detachably covered on the second opening, which is realized by integrally forming or machining a second fastening position on the second cover, and integrally forming or machining a second clamping position on the base that is adapted to the second fastening position. When the second fastening position is clamped with the second clamping position, the second cover is covered on the second opening. Thus, the second cover and the base can be quickly detachably connected without using external tools.

[0015] In some embodiments, a connection wire fastening position capable of detachably connecting with a wire harness is provided on the side wall of the first channel and / or the second cover. Thus, it can be ensured that the wire harness in the first channel can be routed neatly.

[0016] According to another aspect of the present application, an environment perception device is provided, which includes a perception unit for perceiving the environment, an antenna module, and the foregoing vehicle-mounted antenna mounting structure. The perception unit and the antenna module are mounted on the vehicle-mounted antenna mounting structure.

[0017] Since the environment perception device of the present application integrates the antenna module and the perception unit capable of perceiving the environment on the first bracket, when the vehicle installs the environment perception device through the first bracket, the antenna module and the perception unit are integrally installed, and the installation and disassembly are fast. Moreover, since the antenna module and the perception unit are integrated together, the length of the signal transmission wire harness between the antenna module and the perception unit can be greatly reduced, reducing signal attenuation while reducing costs.

[0018] In some embodiments, the perception unit includes a first circuit board; the antenna module includes a second circuit board, an antenna mounted on the second circuit board, and a wire harness electrically connected to the second circuit board; the wire harness is electrically connected to the first circuit board. Since the second circuit board of the antenna module is electrically connected to the first circuit board of the perception unit through the wire harness, the length of the signal transmission wire harness can be greatly reduced, reducing signal transmission attenuation while reducing costs.

[0019] In some embodiments, the second circuit board is detachably connected to the first bracket. Thus, the maintenance and replacement of the second circuit board can be facilitated.

[0020] In some embodiments, the detachable connection between the second circuit board and the first bracket is realized, for example, by providing a screw hole column with a first screw hole in the first accommodation cavity of the base of the first bracket, and providing a first through hole on the antenna module that corresponds to and is adapted to the first screw hole on the screw hole column. Thus, the antenna module can be detachably connected to the base by screwing a screw through the first through hole and threading it with the first screw hole on the screw hole column. Preferably, four screw hole columns are provided and are respectively located at the four corners of the second circuit board to improve the connection strength and stability between the second circuit board and the screw hole column.

[0021] In some embodiments, when only one of the base and the first cover of the first bracket does not block the signal receiving surface of the antenna, the other is made of metal, for example; the antenna is arranged on the side of the second circuit board facing the non-blocking component, and / or the four sides of the antenna face the non-blocking component. Since the side of the antenna facing away from the second circuit board and the four sides all face the base or the first cover that does not block the signal receiving surface of the antenna, even if the antenna is accommodated between the base and the first cover, the electromagnetic waves transmitted to the antenna will not be significantly blocked or interfered by the base and the first cover.

[0022] In some embodiments, the first receiving cavity of the base in the first bracket is adapted to the shape of the second circuit board. Thus, the second circuit board can be quickly positioned through the first receiving cavity to achieve rapid alignment of the first through hole with the first screw hole on the screw hole column, facilitating the connection of the second circuit board and the base by screws.

[0023] In some embodiments, the sensing unit includes at least one of a binocular camera, a laser radar, a front-view integrated machine, a terahertz sensing imaging module, a rear-view camera, an excitation system, and a front-view camera. When the sensing unit is a binocular camera, the second circuit board of the antenna module can be electrically connected to the left and / or right circuit boards of the binocular camera through a wiring harness. Preferably, the wiring harness of the second circuit board of the antenna module is electrically connected to the right circuit board of the binocular camera to minimize the length of the signal transmission harness, thereby reducing the attenuation of signal transmission while reducing costs. When the sensing unit includes a laser radar, the antenna module is arranged on top of the laser radar. As a result, the antenna module can receive a stronger signal.

[0024] In some embodiments, the binocular camera includes a left eye and a right eye arranged on a first bracket, and the antenna module is arranged on the first bracket between the left eye and the right eye. Thus, the structure of the environment perception device can be made compact.

[0025] According to another aspect of the present application, a vehicle is provided, which includes a windshield bracket seat; and the aforementioned environmental perception device; wherein, the environmental perception device is detachably connected to the windshield bracket seat. By integrating the antenna module with the perception unit capable of perceiving the environment to form an environmental perception device, and through the detachable connection between the environmental perception device and the windshield bracket seat, the problem of rapid installation and disassembly of the environmental perception device integrated with the perception unit and the antenna module on the vehicle is solved. The detachable connection between the environmental perception device and the windshield bracket seat is realized, for example, by integrally forming or machining at least one first mounting position and a second mounting position on the base, and integrally forming, machining or installing a first mounting buckle and a second mounting buckle on the windshield bracket seat. The first mounting buckle and the second mounting buckle correspond to the first mounting position and the second mounting position, and the environmental perception device and the windshield bracket seat are quickly installed and disassembled by engaging the first mounting position and the second mounting position with the first mounting buckle and the second mounting buckle respectively, and the operation process does not require tools and is convenient to operate.

[0026] In some embodiments, the windshield bracket seat and the environmental perception device are arranged such that the windshield bracket seat does not block the antenna receiving surface of the antenna module of the environmental perception device. Thus, the antenna receiving signal of the antenna module can be ensured to be strong.

[0027] In some embodiments, the angle between the receiving surface of the antenna of the antenna module and the horizontal plane is set to a preset angle, and the receiving surface of the antenna is arranged facing the sky. Thus, it can be ensured that the antenna module transmits and receives strong signals.

[0028] In some embodiments, the windshield bracket seat is provided with a second channel corresponding to the antenna receiving surface of the antenna module of the environmental perception device. To avoid the windshield bracket seat blocking the antenna module from receiving signals.

[0029] In some embodiments, the preset angle is set such that the difference between the angle between the receiving surface of the antenna and the windshield of the vehicle is less than 10°. By setting the angle between the receiving surface of the antenna and the windshield to be relatively small, the antenna can receive strong signals. In particular, when the receiving surface of the antenna is parallel to the windshield, generally, the angle between the windshield and the horizontal plane is about 26°. Thus, it can be ensured that the antenna receiving surface can be arranged facing the sky, maximizing the signals received by the antenna.

[0030] In some embodiments, a rain sensor, a USB, and / or an ETC are also provided on the windshield bracket seat. Thus, the length of the wire harness connected to the rain sensor, the USB, and the ETC can be reduced, and the cost can be lowered. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In this document, the antenna in the term "antenna module" may refer to a GNSS (Global Navigation Satellite System) antenna, or other antennas that can achieve vehicle sensor data transmission.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0053] Figures 1 to 5 Schematically shows a vehicle antenna mounting structure according to an embodiment of this application.

[0054] As Figure 1 shown, the vehicle antenna mounting structure selects the first bracket of the binocular camera 3. As Figure 3 shown, the first bracket includes a base 303; a first receiving cavity 3034 is integrally formed or processed on the base 303, and the first receiving cavity 3034 is used to receive the antenna module 2; the first receiving cavity 3034 communicates with the outside through a first opening 3035; the size of the first opening 3035 allows the antenna module 2 to enter and exit the first receiving cavity 3034.

[0055] In this application, the antenna module 2 and the sensing unit capable of sensing the environment are integrated on the first bracket. When it is necessary to install the antenna module 2 and the sensing unit on a vehicle, only the first bracket needs to be installed on the vehicle, for example, on the windshield. The windshield can be, for example, the front windshield or the rear windshield; moreover, since the antenna module 2 and the sensing unit are integrated together, the length of the signal transmission wire harness 204 between the antenna module 2 and the sensing unit can be greatly reduced, reducing signal attenuation while reducing costs; in addition, since there is no need to separately set the base of the antenna module 2, the production efficiency is improved while the production cost is reduced.

[0056] In some embodiments, the first receiving cavity 3034 is set to be adapted to the outer shape of the antenna module 2 to quickly position the antenna module 2 through the first receiving cavity 3034.

[0057] In some embodiments, as Figure 4As shown, a screw hole column 3033 is integrally formed, processed or connected in the first accommodation cavity 3034 of the base 303. A first screw hole is processed on the screw hole column 3033, so that the antenna module 2 can be installed on the base 303 through a screw 203. Preferably, four screw hole columns 3033 are provided, and they respectively correspond to the four corners of the antenna module 2 to improve the connection strength and stability between the antenna module 2 and the screw hole columns 3033.

[0058] In some embodiments, as Figure 5 shown, on the basis of including the base 303, the first bracket of the vehicle-mounted antenna installation structure further includes a first cover 301. A first buckling position 3011 is integrally formed, processed or connected on the first cover 301; a first clamping position 3038 is integrally formed or processed on the base 303; the first cover 301 and the base 303 are clamped and connected through the first buckling position 3011 and the first clamping position 3038; when the first cover 301 is clamped and connected to the base 303, the first cover 301 covers the first opening 3035 (as Figure 1 , Figure 3 and Figure 6 shown), to prevent the antenna module 2 from being easily aged due to direct exposure to the natural environment, and also prevent dust and water from seeping into the first accommodation cavity 3034, generally meeting the requirements of the IP5K2 waterproof grade; when the first cover 301 is disassembled from the base 303 (as Figure 4 and Figure 5 shown), the antenna module 2 can be taken out from the first accommodation cavity 3034 of the base 303. Preferably, two groups of first buckling positions 3011 are provided on the front side and the rear side of the first cover 301, or two groups of first buckling positions 3011 are provided on the left side and the right side, to improve the clamping connection stability between the first cover 301 and the base 303.

[0059] In some embodiments, the base 303 and / or the first cover 301 are made of non-conductive materials with a relatively low dielectric constant such as ABS, polycarbonate or polypropylene materials. Further, these materials do not add conductive materials such as carbon fiber and metal powder, nor reinforcing materials such as glass fiber, to ensure the low dielectric constant of the materials. Thus, even if the base 303 and the first cover 301 made of these materials are arranged on the signal transmission path of the antenna module 2, the signal will not be reflected or absorbed by the base 303 and the first cover 301 before being transmitted to the antenna module 2, that is, the base 303 and the first cover 301 will not affect the signal transmission of the antenna module 2.

[0060] In some other embodiments, the base 303 and / or the first cover 301 are made of materials with a small loss tangent value such as polypropylene. Thus, even if the base 303 and the first cover 301 made of these materials are arranged on the signal transmission path of the antenna module 2, the signal loss is small before being transmitted to the antenna module 2, that is, the base 303 and the first cover 301 do not affect the signal transmission of the antenna module 2.

[0061] In some embodiments, the thickness of the base 303 and / or the first cover 301 is less than 3 mm. Thereby, while avoiding the direct exposure of the antenna module 2 to the natural environment, the signal attenuation received by the antenna module 2 caused by the first cover 301 and / or the base 303 can be avoided.

[0062] In this application, by selecting a material that does not affect the signal transmission of the antenna module 2 as the material of at least one of the base 303 and the first cover 301; and / or setting the thickness of at least one of the base 303 and the first cover 301 to be below 3 mm, the antenna module 2 covered between the base 303 and the first cover 301 can avoid being directly exposed to the natural environment, and will not cause signal attenuation of the antenna module 2 due to the base 303 and / or the first cover 301 being arranged on the signal transmission path, that is, it realizes that there is no signal blockage on the receiving surface of the antenna 201 of the antenna module 2, so that the antenna module 2 can receive a stronger signal.

[0063] In some embodiments, as Figure 4 shown, a first channel 3036 is integrally formed or processed on the base 303; the first channel 3036 is used to communicate the mounting position of the binocular camera 3 with the first accommodation cavity 3034; the first channel 3036 is used to accommodate the wiring harness 204 of the antenna module 2. Thereby, the wiring of the wiring harness 204 of the antenna module 2 can be made not to be exposed, avoiding the direct exposure of the wiring harness 204 to the natural environment, slowing down the aging speed of the wiring harness 204, and improving the appearance beauty of the vehicle.

[0064] In some embodiments, as Figure 5 shown, the first channel 3036 communicates with the outside through a second opening 3037; on the basis of including the base 303, the first bracket further includes a second cover 302; a second fastening position 3021 is integrally formed or processed on the second cover 302, and a second clamping position 3039 adapted to the second fastening position 3021 is integrally formed or processed on the base 303. When the second fastening position 3021 is clamped with the second clamping position 3039, the second cover 302 covers the second opening 3037 (as Figure 7As shown), to prevent dust and water from penetrating into the first channel 3036, which can generally meet the requirements of IP5K2 waterproof level. Therefore, during use, the appearance of the vehicle-mounted antenna installation structure is maintained by the second cover 302 to prevent the wiring harness 204 from being exposed; the second opening 3037 can also be opened by the second cover 302 to facilitate the adjustment of the routing of the wiring harness 204 or the maintenance of the wiring harness 204. Preferably, the second cover 302 is made of plastic material for easy processing. Preferably, the second cover 302 is provided with second buckling positions on at least two sides, and at least one side of the second buckling positions is provided with two groups to improve the stability of the second cover 302 and the base 303 engagement connection. Preferably, the second opening 3037 is provided on the side of the base 303 that is away from the left eye 304 and the right eye 305, so that the routing of the wiring harness 204 in the first channel 3036 can be adjusted or maintained without removing the vehicle-mounted antenna installation structure from the vehicle.

[0065] In some embodiments, Figure 3 As shown, a connection line buckle position 30361 that can be detachably connected to the wire harness 204 is provided on the side wall of the first channel 3036 and / or the second cover 302. The connection line buckle position 30361 can be, for example, a wire clip or a buckle. Thus, it can be ensured that the wire harness 204 in the first channel 3036 can be neatly routed.

[0066] The sensing unit includes binocular camera 3, laser radar 40, front-view integrated machine, terahertz sensing imaging module, rear-view camera, front-view camera, excitation system (device combining laser radar and camera), and other types of sensors, and the sensing unit is used for the environment sensing device. That is, in other embodiments, binocular camera 3 can also be replaced by laser radar 40, front-view integrated machine, terahertz sensing imaging module, front-view camera, excitation system, etc.

[0067] In other embodiments, the detachable connection between the first cover body 301 and the base 303 is realized as follows: a second screw hole is processed on the base 303; a second through hole corresponding to and matching the second screw hole is integrally formed or processed on the first cover body 301; the base 303 and the first cover body 301 are connected by screws.

[0068] In some other embodiments, the base 303 is processed with a first internal thread, the first cover 301 is processed with a first external thread matching the first internal thread, and the first cover 301 is connected to the base 303 through threads.

[0069] In some further embodiments, a first pin hole is integrally formed or processed on the base 303; a second pin hole is integrally formed or processed on the first cover 301; the second pin hole corresponds to the first pin hole, and the first cover 301 and the base 303 are connected by pins.

[0070] In some other embodiments, the detachable connection between the second cover 302 and the base 303 is realized as follows: a third screw hole is machined on the base 303; a third through hole corresponding to and adapted to the third screw hole is integrally formed or machined on the second cover 302; the base 303 and the second cover 302 are connected by screws.

[0071] In still some other embodiments, a second internal thread is machined on the base 303, and a second external thread adapted to the second internal thread is machined on the second cover 302. The second cover 302 and the base 303 are connected by threads.

[0072] In still other embodiments, a third pin hole is integrally formed or machined on the base 303; a fourth pin hole is integrally formed or machined on the second cover 302; the fourth pin hole corresponds to the third pin hole, and the second cover 302 and the base 303 are connected by a pin.

[0073] Figures 8 to 12 An environmental perception device according to an embodiment of the present application is schematically shown.

[0074] As Figure 9 shown, the environmental perception device includes a perception unit, an antenna module 2, and the aforementioned vehicle-mounted antenna installation structure. The perception unit is used to perceive the environment. The perception unit and the antenna module 2 are installed on the vehicle-mounted antenna installation structure. Thus, when the vehicle installs this environmental perception device, the antenna module 2 and the perception unit are integrally installed, and the installation and disassembly are fast; moreover, since the antenna module 2 and the perception unit are integrated, the length of the signal transmission wire harness 204 between the antenna module 2 and the perception unit can be greatly reduced, reducing signal attenuation while reducing costs.

[0075] In some embodiments, taking the binocular camera 3 as an example of the perception unit, the binocular camera 3 includes a first circuit board; as Figure 11 shown, the antenna module 2 includes a second circuit board 202, an antenna 201 installed on the second circuit board 202, and a wire harness 204 electrically connected to the second circuit board 202; the wire harness 204 is electrically connected to the first circuit board. Thus, the length of the signal transmission wire harness 204 can be greatly reduced, reducing signal transmission attenuation while reducing costs. The antenna 201 can be, for example, a ceramic antenna. The first circuit board can be the circuit board of the left eye 304 and / or the right eye 305 of the binocular camera 3. Preferably, as Figure 12 shown, the wire harness 204 of the antenna module 2 is electrically connected to the circuit board of the right eye 305 of the binocular camera 3 to minimize the length of the signal transmission wire harness 204, reducing signal transmission attenuation while reducing costs. Preferably, as Figure 9 shown, the antenna module 2 is disposed on the first bracket between the left eye 304 and the right eye 305 to make the structure of the environmental perception device compact. Preferably, as Figure 4 、Figures 9 to 11 As shown, on the basis that the first accommodating cavity 3034 of the base 303 is provided with a screw hole column 3033, a first through hole 2021 is integrally formed or processed on the second circuit board 202, and the first through hole 2021 corresponds to and fits with the first screw hole on the screw hole column 3033. Thus, the antenna module 2 can be detachably connected to the base 303 by passing the screw 203 through the first through hole 2021 and being threadedly connected with the first screw hole on the screw hole column 3033 (such as Figure 9 As shown); further, the first accommodating cavity 3034 of the base 303 in the first bracket is adapted to the shape of the second circuit board 202, and the second circuit board 202 can be quickly positioned through the first accommodating cavity 3034 to achieve rapid alignment of the first through hole 2021 with the first screw hole on the screw hole column 3033, so that the second circuit board 202 and the base 303 are connected by the screw 203; when the antenna module 2 needs to be replaced or repaired, the antenna module 2 and the base 303 can also be disassembled by removing the screw 203 from the screw hole column 3033 (as shown in FIG. Figure 10 shown).

[0076] In some embodiments, when only one of the base 303 of the first bracket and the first cover 301 does not block the signal receiving surface of the antenna 201, the other is made of metal, for example; the antenna 201 is arranged on the side of the second circuit board 202 facing the non-blocking component, and / or the surroundings of the antenna 201 face the non-blocking component. Figure 9 and Figure 10 As shown, when the base 303 is made of metal and the first cover 301 is made of ABS, polycarbonate or polypropylene, the antenna 201 is arranged on the side of the second circuit board 202 facing the first cover 301; and when the first cover 301 is connected to the base 303, the surroundings of the antenna 201 are also facing the first cover 301. Since the side of the antenna 201 that is away from the second circuit board 202 and the surroundings are all facing the base 303 or the first cover 301 that does not block the signal on the antenna receiving surface, even if the antenna 201 is accommodated between the base 303 and the first cover 301, the electromagnetic waves transmitted to the antenna 201 will not be significantly blocked or interfered by the base 303 and the first cover 301.

[0077] In other embodiments, the detachable connection between the second circuit board 202 and the first bracket is achieved, for example, by providing a rotatable baffle in the first accommodating cavity 3034, and the second circuit board 202 and the first bracket can be installed and removed by rotating the baffle.

[0078] In some embodiments, the sensing unit includes at least one of a binocular camera 3, a laser radar 40, a front-view integrated machine, a terahertz sensing imaging module, a rear-view camera, a front-view camera, and an excitation system.Figure 13 As shown, when the sensing unit includes the lidar 40, the second bracket of the lidar 40 serves as a vehicle-mounted antenna mounting structure. The second bracket includes a second base 41. The lidar 40 is disposed on one side of the second base 41, such as the front side; the antenna module 2 is disposed on the top of the second base 41. Thus, the antenna module 2 can receive a stronger signal.

[0079] Figures 14 to 16 Schematically shows an environmental sensing device of the windshield bracket base 1 disposed on a vehicle according to an embodiment of the present application.

[0080] As Figure 14 shown, the vehicle includes a windshield bracket base 1 and the aforementioned environmental sensing device. As Figure 15 shown, the windshield bracket base 1 is integrally formed, processed or connected with a first mounting buckle 101 and / or a second mounting buckle 102; as Figure 4 shown, in the vehicle-mounted antenna mounting structure of the environmental sensing device, the base 303 of the first bracket is integrally formed or processed with a first mounting position 3031 corresponding to the first mounting buckle 101 and capable of being snap-connected, and / or is provided with a second mounting position 3032 corresponding to the second mounting buckle 102 and capable of being snap-connected. Thus, without using external tools, the quick disassembly of the windshield bracket base 1 and the base 303 of the first bracket can be achieved. In the present application, the antenna module 2 and the sensing unit capable of sensing the environment are integrated into an environmental sensing device, and the environmental sensing device is detachably connected to the windshield bracket base 1 (as Figure 16 shown), which solves the problem of quick installation and disassembly of the environmental sensing device integrated with the sensing unit and the antenna module 2 on the vehicle.

[0081] Preferably, as Figure 4 and Figure 5 shown, at least two groups of first mounting positions 3031 are provided and arranged along the arrangement direction of the left eye 304 and the right eye 305 of the binocular camera 3 to improve the connection stability between the first mounting position 3031 and the first mounting buckle 101.

[0082] Preferably, as Figure 4 and Figure 5 shown, at least two groups of second mounting positions 3032 are provided and arranged along the arrangement direction of the left eye 304 and the right eye 305 of the binocular camera 3 to improve the connection stability between the second mounting position 3032 and the second mounting buckle 102.

[0083] Preferably, as Figure 4 and Figure 5As shown, the first mounting position 3031 and the second mounting position 3032 are arranged perpendicular to the arrangement direction of the left eye 304 and the right eye 305, so as to improve the connection stability between the first mounting position 3031 and the first mounting buckle 101, and improve the connection stability between the second mounting position 3032 and the second mounting buckle 102.

[0084] Preferably, as Figure 4 shown, the two groups of first mounting positions 3031 are respectively installed on both sides of the first accommodating cavity 3034 and are located inside the left eye 304 and the right eye 305, so as to ensure the installation stability of the antenna module 2 in the first accommodating cavity 3034 and will not additionally increase the lateral dimension of the windshield bracket base 1.

[0085] Preferably, as Figure 4 shown, the two groups of second mounting positions 3032 are respectively installed on both sides of the first accommodating cavity 3034 and are located inside the left eye 304 and the right eye 305, so as to ensure the installation stability of the antenna module 2 in the first accommodating cavity 3034 and will not additionally increase the lateral dimension of the windshield bracket base 1.

[0086] Preferably, as Figure 4 and Figure 5 shown, the first mounting position 3031 and the second mounting position 3032 are respectively installed on both sides of the first accommodating cavity 3034 and are located inside the left eye 304 and the right eye 305, so as to ensure the installation stability of the antenna module 2 in the first accommodating cavity 3034 and will not additionally increase the lateral dimension of the windshield bracket base 1.

[0087] Preferably, as Figure 15 shown, the first mounting buckle 101 and the second mounting buckle 102 are centrally arranged on the windshield bracket base 1 to ensure the installation stability of the environmental perception device.

[0088] In some other embodiments, the detachable connection between the windshield bracket base 1 and the base 303 is realized as follows: a fourth screw hole is machined on the base 303; a fourth through hole corresponding to and adapted to the fourth screw hole is integrally formed or machined on the windshield bracket base 1; the base 303 and the windshield bracket base 1 are connected by screws.

[0089] In some other embodiments, a third internal thread is machined on the base 303, an external thread adapted to the third internal thread is machined on the windshield bracket base 1, and the first cover body 301 is threadedly connected to the base 303.

[0090] In some other embodiments, a fifth pin hole is integrally formed or machined on the base 303; a sixth pin hole is integrally formed or machined on the windshield bracket base 1; the sixth pin hole corresponds to the fifth pin hole, and the windshield bracket base 1 is connected to the base 303 by a pin.

[0091] In some preferred embodiments, a fifth through-hole corresponding to the left eye 304 and the right eye 305 is integrally formed or machined on the windshield support base 1.

[0092] In some preferred embodiments, as Figure 16 shown, a second channel 103 is integrally formed or machined at the position corresponding to the receiving surface of the antenna 201 of the antenna module 2 of the environmental perception device on the windshield support base 1. The second channel 103 can be, for example, a through groove or a through hole. Thus, it is possible to avoid the windshield support base 1 from blocking the receiving surface of the antenna of the antenna module 2 of the environmental perception device, so as to avoid the windshield support base 1 from blocking the antenna module 2 from receiving signals and ensure the signal receiving strength of the antenna of the antenna module 2. Preferably, as Figure 16 shown, when the first cover 301 does not block the signal transmission and the base 303 blocks the signal transmission, the second channel 103 is provided on the side of the first cover 301 facing away from the base 303 to ensure the signal transmission strength.

[0093] In some preferred embodiments, the included angle between the receiving surface of the antenna 201 of the antenna module 2 and the horizontal plane is set to a preset angle; the preset angle is set such that the difference between the included angle between the receiving surface of the antenna 201 and the windshield of the vehicle is less than 10°, and the receiving surface of the antenna 201 faces the sky. By setting the included angle between the receiving surface of the antenna 201 and the windshield to be relatively small, the antenna 201 can receive stronger signals. In particular, when the receiving surface of the antenna 201 is parallel to the windshield, the signal received by the antenna 201 is the largest.

[0094] In some preferred embodiments, a rain sensor, a USB, and / or an ETC are also provided on the windshield support base 1. Thus, the length of the wire harness 204 connected to the rain sensor, the USB, and the ETC can be reduced, and the cost can be lowered.

[0095] In this application, the connection or installation is a fixed connection without special emphasis. The fixed connection can be realized as a detachable connection or a non-detachable connection commonly used in the prior art. The detachable connection can be realized by the prior art, such as threaded connection, key connection, snap connection, etc. The non-detachable connection can also be realized by the prior art, such as welding or gluing.

[0096] The above are only some embodiments of this application. For those of ordinary skill in the art, without departing from the creative concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application.
