Description

Technical Field

[0001] The utility model belongs to the technical field of automobile equipment, and in particular relates to a GNSS antenna installation structure and an automobile. Background Art

[0002] With the continuous development of science and technology, the Global Navigation Satellite System (GNSS) technology has gradually expanded from past military applications to commercial and civilian fields. GNSS technology is widely used in automobile navigation, aerospace, marine surveying and mapping, logistics and transportation, etc. with its high-precision navigation and positioning capabilities. At the same time, with the advancement of technology, GNSS technology is also constantly innovating and upgrading, bringing new possibilities to all walks of life. In the field of automobile navigation, GNSS technology is one of the cores of realizing intelligent driving. With the help of GNSS technology, vehicles can obtain their own position and speed information in real time, and perform intelligent path planning and navigation guidance. With the development of GNSS technology, more accurate vehicle positioning and navigation will be achieved, improving driving safety and convenience. The choice of the installation position of the GNSS antenna on the vehicle body is also very important. There should be no sheet metal blocking directly above the GNSS antenna, and it must also meet the requirements of convenient maintenance and disassembly. A common solution is to arrange it in the cavity of the roof crossbeam and install it from the roof. At the same time, a plastic decorative cover needs to be added to the roof to prevent the antenna signal from being blocked and to be able to be removed for maintenance. The disadvantage of this solution is that it is inconvenient during maintenance because the roof is at a high position and operation is difficult. At the same time, the decorative cover is generally snapped or glued, and the buckle is easily damaged during removal, and the strength of the glue is easily reduced after removal, resulting in the decorative cover being not firmly fixed. Utility Model Content

[0003] The utility model aims to provide a GNSS antenna installation structure and a car. The GNSS antenna installation structure is located in the rear windshield area. The GNSS antenna can be installed on the rear crossbeam assembly of the roof from the bottom of the car. Compared with the existing antenna installed on the roof, the installation is convenient and quick. When the GNSS antenna needs to be repaired, it is only necessary to dismantle the rear edge of the roof in the car, and the risk of damage to the vehicle is relatively small. At the same time, the rear windshield is located above the rear crossbeam assembly of the roof where the GNSS antenna installation structure is located, so there is no need to add a decorative cover structure, which reduces the cost. The installation position of the GNSS antenna is located behind the head profile envelope, which increases the head space in the car, is conducive to reducing the height of the car, reducing the weight and wind resistance of the whole vehicle, and improving the economy of the vehicle.

[0004] The specific contents of the plan are as follows:

[0005] A GNSS antenna mounting structure includes the mounting structure being arranged in a roof rear cross beam assembly, the roof rear cross beam assembly being arranged at the rear of a seam separating a vehicle roof and a rear windshield, and being located in a housing space formed by the rear windshield and the ceiling, the mounting structure including at least one antenna mounting through hole.

[0006] At least one antenna mounting through hole is provided on the rear cross beam of the top cover of the present GNSS antenna mounting structure, and the GNSS antenna is fixedly installed in the antenna mounting through hole through an antenna mounting bracket. The rear cross beam assembly of the top cover is located between the rear windshield and the ceiling, that is, the rear windshield is above the rear cross beam assembly of the top cover, and the ceiling is located below the rear cross beam assembly of the top cover. The rear cross beam assembly of the top cover is located as a whole at the rear of the seam between the roof and the rear windshield, that is, at the rear of the envelope line of the roof profile. There is no sheet metal above the antenna mounting structure, which will not block the antenna signal, and the decorative cover can be omitted if it is set below the windshield, saving costs.

[0007] The GNSS antenna installation structure of the utility model is located behind the head profile envelope of the vehicle roof, which increases the vertical space for the passenger's head. Compared with the traditional installation position set on the roof, the utility model does not need to increase the height of the roof to increase the head space and improve comfort, which helps to reduce the height, weight and wind resistance of the whole vehicle and improve economy.

[0008] When the utility model installs the antenna, the GNSS antenna is installed on the antenna mounting frame, and then inserted from the lower end of the antenna mounting through hole and sleeved in the antenna mounting through hole, the bolt holes of the two outgoing mounting plates of the antenna mounting frame are aligned with the bolt holes of the lower plate of the rear cross beam of the top cover, the screw rod of the bolt is inserted into the bolt hole of the outgoing mounting plate and then passed out from the bolt hole of the lower plate of the rear cross beam of the top cover, and is threadedly fixedly connected with the corresponding nut welded on the upper end surface of the lower plate of the rear cross beam of the top cover. The bolt head of the bolt is fixed on the lower end surface of the lower plate of the rear cross beam of the top cover, and this arrangement is convenient for installation. After the GNSS antenna is installed and fixed, glue is applied to form a second glue surface at a distance of 20mm behind the first glue surface at the front end of the welding edge of the upper plate and the lower plate of the rear cross beam of the top cover, and the upper edge of the rear windshield is aligned and bonded to the second glue surface to complete the installation of the GNSS antenna.

[0009] When the antenna installed by the utility model needs to be repaired, the rear edge of the roof can be removed from the inside of the car for repair, which is simple and convenient. The traditional antenna is installed on the roof, which is too high, making it difficult to operate during repair and easily causing damage to the roof; the antenna set on the roof is also installed with a decorative cover, which is generally snap-fitted or glued, and the buckle is easily damaged during removal, and the strength of the adhesive is easily reduced after removal, resulting in the decorative cover being not firmly fixed. Compared with the solution of removing the decorative cover from the roof, the solution of only removing the rear part of the ceiling is more convenient.

[0010] Furthermore, the roof cover rear cross beam assembly includes a roof cover rear cross beam upper plate and a roof cover rear cross beam lower plate, the edges of the roof cover rear cross beam upper plate and the roof cover rear cross beam lower plate are welded and fixed, a cavity is formed between the roof cover rear cross beam upper plate and the roof cover rear cross beam lower plate, the roof cover rear cross beam upper plate is provided with at least one downward lower flange hole, the roof cover rear cross beam lower plate is provided with an upper flange hole that matches the position and shape of the lower flange hole, and the lower flange holes and upper flange holes with corresponding positions constitute an antenna mounting through hole.

[0011] The upper plate of the rear cross beam of the top cover and the lower plate of the rear cross beam of the top cover of the top cover assembly are welded together at the edges, and a gap is provided between the upper plate of the rear cross beam of the top cover and the lower plate of the rear cross beam of the top cover to form a cavity. There is at least one downward lower flange hole on the upper plate of the rear cross beam of the top cover, and at least one upward upper flange hole on the lower plate of the rear cross beam of the top cover. The lower flange hole and the upper flange hole corresponding in position together constitute an antenna mounting through hole. Because the corresponding upper flange hole and the lower flange hole constitute an antenna mounting hole, the number of the upper flange hole and the lower flange hole matches the number of the antenna mounting through hole. The GNSS antenna is fixedly installed in the antenna mounting through hole through the antenna mounting bracket. The setting of the flange hole can ensure that the sheet metal has sufficient strength without stress concentration, and at the same time can ensure that the GNSS antenna receiving signal is not blocked.

[0012] Furthermore, the horizontal distance between the hole wall of the antenna mounting through hole and the outer wall of the GNSS antenna is 4-8 mm.

[0013] The safety distance between the hole wall of the antenna installation through hole and the outer wall of the GNSS antenna is between 4mm and 8mm. The setting of the safety distance can ensure the convenience of the installation distance. Not exceeding 8mm is to control the width of the rear beam of the top cover, reduce the weight of the vehicle and save costs.

[0014] Furthermore, it includes at least one antenna mounting bracket, each antenna mounting bracket includes a mounting bracket body and two extending mounting plates, the mounting bracket body is a cylinder and four mounting holes are evenly distributed on the bottom of the cylinder, the two extending mounting plates are symmetrically arranged on the side wall of the lower end of the mounting bracket body, the mounting bracket body is sleeved in the antenna mounting through hole, the two extending mounting plates are exposed outside the lower end surface of the lower plate of the rear cross beam of the top cover and are screwed and fixed to the lower plate of the rear cross beam of the top cover by bolts and nuts, and the nuts are welded to the upper end surface of the lower plate of the rear cross beam of the top cover.

[0015] The GNSS antenna mounting structure of the utility model also includes an antenna mounting bracket, which is used to fix the GNSS antenna in the antenna mounting through hole of the rear cross beam assembly of the top cover. The number of antenna mounting brackets matches the number of antenna mounting through holes. The shape and size of the mounting bracket body of the antenna mounting bracket matches the shape and size of the GNSS antenna. There is a mounting hole at the bottom of the mounting bracket body, and the GNSS antenna is fixed in the mounting hole by screws. The GNSS antenna can be installed and fixed in the mounting bracket body. The mounting bracket body with the installed GNSS antenna is inserted into the antenna mounting through hole from below, and the two expenditure mounting plates are pressed against the lower end surface of the lower plate of the rear cross beam of the top cover. Threaded mounting holes are provided at the positions corresponding to the expenditure mounting plates and the lower plate of the rear cross beam of the top cover. The screw of the bolt is inserted into the threaded mounting hole from the lower end surface of the lower plate of the rear cross beam of the top cover, and then passes through the upper end surface of the lower plate of the rear cross beam of the top cover and is screwed with the nut that has been welded and fixed on the upper end surface of the lower plate of the rear cross beam of the top cover. The nut is welded on the upper end surface of the lower plate of the rear cross beam of the top cover for easy installation. Because the edges of the upper plate of the rear cross beam of the top cover and the lower plate of the rear cross beam of the top cover are welded together, the nut is welded on the lower plate of the rear cross beam of the top cover in advance. When installing the GNSS antenna, the GNSS antenna connected to the mounting bracket installed on the antenna mounting bracket is inserted from the bottom of the antenna installation through hole. When the expenditure mounting plate is close to the lower end surface of the lower plate of the rear cross beam of the top cover, the bolt is inserted into the threaded mounting hole of the expenditure mounting plate. The screw of the bolt passes upward through the upper end surface of the lower plate of the rear cross beam of the top cover and penetrates into the nut. Tighten the bolt to fix the expenditure mounting plate thread on the lower plate of the rear cross beam of the top cover. The bolt can be a glue-coated bolt, which has a very good anti-loosening effect.

[0016] Furthermore, each expenditure mounting plate is arranged between a front point and a rear point of the projection of the GNSS antenna on the longitudinal axis of the vehicle body.

[0017] The two outgoing mounting plates of each antenna mounting bracket are arranged between the frontmost point and the rearmost point of the projection of the GNSS antenna on the longitudinal axis of the car, that is, no point of the two outgoing mounting plates should exceed the frontmost point and the rearmost point, so that the width of the beam, that is, the longitudinal distance of the car, can be shortened, the weight of the beam can be reduced, and the cost can be saved.

[0018] Furthermore, the upper end surfaces of the welding edges of the front ends of the upper plate of the rear cross beam of the roof cover and the lower plate of the rear cross beam of the roof cover are provided with a first adhesive bearing surface, the roof is bonded to the first adhesive bearing surface, the second adhesive bearing surface is arranged behind the first adhesive bearing surface, and the rear windshield is bonded to the second adhesive bearing surface.

[0019] The upper end surface of the welding edge of the roof cross beam assembly is provided with a first adhesive surface, on which adhesive is applied for bonding and fixing with the rear edge of the roof. A spacing of 20 mm is provided between the second adhesive surface and the first adhesive surface, on which adhesive is applied for bonding the rear windshield.

[0020] Furthermore, two antenna mounting through holes are respectively arranged at the left and right ends of the rear cross beam assembly of the top cover, and the line connecting the center points of the two antenna mounting through holes is substantially parallel to the upper edge of the rear windshield.

[0021] Providing an antenna installation through hole on the rear cross beam of the top cover is a basic setting, but not the best setting. The best solution for the GNSS antenna installation structure of the utility model is to provide two antenna installation through holes at the left and right ends of the rear cross beam assembly of the top cover, and the line connecting the center points of the two antenna installation through holes is basically parallel to the upper edge of the rear windshield.

[0022] A car comprises the GNSS antenna mounting structure.

[0024] 1. The antenna installation through hole of the utility model is arranged on the rear cross beam assembly of the roof, and the rear cross beam assembly of the roof is located in the accommodation space between the rear windshield and the roof, and is located at the rear of the seam between the roof and the rear windshield. The operator can install it from the bottom outside the vehicle, and the installation is convenient; when repairing, only the rear edge of the roof needs to be removed inside the vehicle, which has a low risk of damage to the vehicle and is simple and convenient to repair;

[0025] 2. The rear crossbeam assembly of the top cover where the GNSS antenna installation structure of the utility model is located is located above the rear windshield, so there is no need to add a decorative cover structure, which reduces costs;

[0026] 3.
