Description

Technical Field

[0001] This utility model relates to the field of receiving antenna technology, specifically to a BeiDou multi-band receiving antenna. Background Technology

[0002] The BeiDou multi-band receiving antenna is a crucial component of the BeiDou satellite navigation system user terminal. It can simultaneously receive signals transmitted by BeiDou satellites on multiple frequency bands. These signals contain satellite position information, time information, and other navigation data. The antenna converts the received weak electromagnetic signals into electrical signals and transmits them to the backend receiver for processing. The receiver analyzes and calculates the signals from multiple frequency bands to determine the user's position, velocity, and time.

[0003] Currently, the outer shell of existing Beidou multi-band receiving antennas generally consists of a shell and a cover assembly. The sealing between the shell and the cover is poor, and moisture can easily enter through the gap between the shell and the cover, causing damage to the internal multi-band receiving antenna body. Furthermore, the shell and the cover are connected by bolts or glued together, making it inconvenient to disassemble later and to repair the internal multi-band receiving antenna body. Utility Model Content

[0004] The purpose of this invention is to provide a BeiDou multi-band receiving antenna to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a BeiDou multi-band receiving antenna, comprising:

[0006] The lower housing has a multi-band receiving antenna body installed inside it, and the top of the lower housing has a shell edge fixed thereon.

[0007] A cover, which is mounted on the lower housing, and a cover edge is fixed to the bottom end of the cover;

[0008] A chassis base, which is mounted on the bottom of the lower housing;

[0009] The cover edge is snapped together with the shell edge. A first sealing groove and a second sealing groove are provided on the lower side of the cover edge and the upper side of the shell edge. A waterproof gasket is provided between the cover edge and the shell edge. A first sealing strip and a second sealing strip are fixed on the upper and lower sides of the waterproof gasket, corresponding to the positions of the first sealing groove and the second sealing groove.

[0010] Preferably, the first sealing groove is fitted outside the second sealing groove, and the first sealing strip is fitted outside the second sealing strip. The first sealing strip matches the first sealing groove, and the second sealing strip matches the second sealing groove, so that the sealing between the edge of the cover and the edge of the shell is good, thereby improving the waterproof performance.

[0011] Preferably, the first and second sealing strips are integrally formed with the waterproof gasket, which is simple to process and easy to form.

[0012] Preferably, the upper edge of the shell edge is provided with multiple slots at equal intervals, and the lower edge of the cover edge is fixed with a block corresponding to each slot. The block is engaged in the slot and is made of elastic metal material, which makes the connection between the cover and the lower shell simple and facilitates disassembly and maintenance later.

[0013] Preferably, a shock-absorbing seat is connected between the chassis base and the lower housing to buffer external vibrations or impacts and protect the main body of the multi-band receiving antenna.

[0014] Preferably, the shock absorber seat is made entirely of rubber material, which provides good shock absorption performance.

[0015] Preferably, the edge of the chassis is provided with mounting holes at equal intervals to facilitate the installation of the BeiDou multi-band receiving antenna.

[0016] Preferably, both the lower housing and the cover are made of ceramic material, which has high dielectric constant stability and low loss characteristics, and is suitable for multi-band signal reception.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] 1. The snap-fit ​​design between the edge of the cover and the edge of the shell makes the connection between the cover and the lower shell simple and easy, and also facilitates disassembly and maintenance later.

[0019] 2. A waterproof gasket is provided between the edge of the cover and the edge of the shell. The first and second sealing strips on the waterproof gasket match the first and second sealing grooves on the edge of the cover and the edge of the shell, which makes the sealing between the edge of the cover and the edge of the shell good, thereby improving the sealing between the cover and the lower shell and improving the waterproof performance.

[0020] 3. By connecting the shock-absorbing seat between the chassis base and the lower shell, external vibrations or impacts are buffered, reducing interference from external factors and improving stability. Attached Figure Description
