Description

Technical Field

[0001] The present invention relates to the technical field of antenna installation, and more particularly to a vehicle-mounted antenna lodging device. Background Art

[0002] With the development of technology, ground military vehicles are equipped with more and more electronic equipment, and vehicle-mounted antennas are used more widely.

[0003] In order to ensure the normal operation of the antenna, the antenna needs to be installed at the highest point on the top of the vehicle body through a bracket. When the bracket reaches a certain height, the vehicle will be too high, affecting the vehicle's passability. Therefore, most antenna brackets are currently designed to be retractable. At present, the vehicle-mounted retractable device generally uses a preset limit support on the base to achieve two fixed states of upright or retracted through simple pin positioning;

[0004] However, the above-mentioned lodging device requires auxiliary tools when operating, which is inefficient. At the same time, the vibration response of the antenna on the top of the device is amplified, and the antenna is more easily damaged during the vibration process. The bolts used are easily damaged due to the high operating frequency. At present, most of the cables inside the lodging device are exposed to the environment, which is easy to cause damage. The sealing of the transmission cable in the device is mainly carried out by silicone rubber potting. The main problem with silicone rubber potting is that the construction period is long, and bubbles are easily generated when the silicone rubber is cured, resulting in sealing failure. After the silicone rubber is cured, it is easy to fall off under the action of external force, and it is also difficult to repair the cable later. Summary of the invention

For example, multiple positioning columns refer to two or more positioning columns. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The present invention is described in detail below.

[0040] like Figure 1-Figure 8 As shown:

[0041] A vehicle-mounted antenna falling device comprises a base 1, a rotating base 2 mounted on the base 1 and hingedly matched with the base 1 around the X-axis direction, a support rod 4 mounted on the rotating base 2 and used for mounting the antenna, a vibration-damping support shaft 5 with elasticity and hingedly connected to the rotating base 2 and the base 1 at both ends, and a locking assembly used in conjunction with the rotating base 2 and the base 1 and used for locking and fixing the antenna in a falling or upright state;

[0042] When the antenna is in an upright position, the support rod 4 is arranged along the Z-axis direction;

[0043] When the antenna is in a lying position, the support rod 4 is arranged along the Y-axis direction.

[0044] The antenna is installed on the top of the support rod 4, and the bottom of the support rod 4 is screwed to the rotating seat 2; by rotating the rotating seat 2 around the X-axis direction, the support rod 4 and the antenna installed on the support rod 4 are in a lying or upright state;

[0045] When the antenna is in an upright state, the support rod 4 is arranged along the Z-axis direction; the antenna in an upright state is locked and fixed by the cooperation of the locking assembly with the rotating seat 2 and the base 1;

[0046] When the antenna is in a lying state, the support rod 4 is arranged along the Y-axis direction; the locking assembly supports and fixes the support rod 4;

[0047] During the antenna shape transformation process, the vibration reduction support shaft 5 is set to effectively avoid damage to the antenna due to vibration during the transformation process;

[0048] In some possible implementations, a rotating shaft 3 is provided on the rotating seat 2, which is hingedly matched with the base 1 and arranged along the X-axis direction; the hinge point between the base 1 and the rotating seat 2 is a hinge point A101, the hinge point between the vibration-damping support shaft 5 and the rotating seat 2 is a hinge point B102, and the hinge point between the vibration-damping support shaft 5 and the base 1 is a hinge point C103;

[0049] The straight line where the hinge point A101 and the hinge point B102 are located, and the straight line where the hinge point A101 and the hinge point C103 are located intersect and form an angle α, α=45°;

[0050] The angle formed by the intersection of the straight line where the hinge point A101 and the hinge point B102 are located and the Z axis, and the angle formed by the intersection of the straight line where the hinge point A101 and the hinge point C103 are located and the Z axis are both β, β = 15° to 30°;

[0051] When the support rod 4 drives the antenna to rotate 45° from the upright state to the inverted state or from the inverted state to the upright state, the hinge point A101, the hinge point B102 and the hinge point C103 will be located on the same straight line. At this time, the elastic vibration-damping support shaft 5 has the maximum elastic compression. When the support rod 4 rotates another 45°, the antenna will follow and will be in the inverted or upright state. At this time, the α formed will be 45°. This ensures that the elastic compression of the vibration-damping support shaft 5 can remain consistent when switching between the inverted and upright states.

[0052] In some possible embodiments, the base 1 includes a chassis 11 hinged to the vibration-damping support shaft 5, and a hinged portion 12 installed on the chassis 11 and hinged to the rotating seat 2; the locking assembly includes a falling lock 7 for fixing the antenna support when the antenna is inverted, and an upright lock 6 used in conjunction with the rotating seat 2 and for locking the antenna when it is upright.

[0053] The inversion locking member 7 includes a support frame 71 with a semicircular arc groove on the top, an arc-shaped pressure plate 72 installed on the top of the support frame 71 and hingedly matched with the support frame 71, and a locking bolt 73 for locking the support frame 71 and the arc-shaped pressure plate 72; the semicircular arc groove and the arc-shaped pressure plate 72 are close to each other and cooperate to form a circular clamping cavity. When the antenna is in a inverted state, the circular clamping cavity is coaxially arranged with the support rod 4 and the inner side surface of the semicircular arc groove will abut against the bottom of the support rod 4, effectively supporting the support rod 4; the support rod 4 is locked in the inverted state by the support frame 71 and the arc-shaped pressure plate, and the setting of the support frame 71 increases the safety and stability of the device in the inverted state;

[0054] When the antenna is in an upright state, the upright locking member 6 connects and fixes the rotating seat 2 and the hinged portion 12 so that the support rod 4 can maintain an upright state.

[0055] In some possible embodiments, an ear seat 61 for use with the upright lock piece 6 is provided on the side of the hinged portion 12 close to the inverted lock piece 7, and a positioning hole 212 for use with the upright lock piece 6 is provided on the side of the rotating seat 2 close to the inverted lock piece 7; when the antenna is upright, the through hole on the ear seat 61 is coaxially connected to the positioning hole 212.

[0056] When the antenna is in an upright state, one end of the upright lock member 6 will pass through the through hole and be inserted into the positioning hole 212, so that the rotating seat 2 cannot rotate around the axis of the rotating shaft 3, so that the support rod 4 can maintain an upright state; when the state is changed, the upright lock member 6 will not be inserted into the positioning hole 212;

[0057] In some possible implementations, in order to effectively achieve the limiting fixation of the rotating seat 2 through the upright lock 6; the upright lock 6 includes a limiting sleeve 62 which is sleeved in the through hole and arranged along the X-axis direction, a limiting shaft 63 which is sleeved in the limiting sleeve 62 and one end of which is used in conjunction with the positioning hole 212, a spring 64 which is sleeved on the outside of the limiting shaft 63 and located in the limiting sleeve 62, and a handle 65 which is installed at the end of the limiting shaft 63 away from the positioning hole 212 and is plugged and matched with the limiting sleeve 62; when the antenna is in an upright state, the end of the limiting shaft 63 away from the handle 65 will pass through the limiting sleeve 62; one end of the spring 64 is connected to the limiting shaft 63 and the other end is connected to the limiting sleeve 62;

[0058] Specifically, a socket is provided on one side of the limiting sleeve 62 close to the handle 65, and an insert block used in conjunction with the socket is provided on the handle 65; when the antenna is in an upright state, the insert block will be inserted into the socket, so that the limiting shaft 63 is fixed and cannot rotate in the limiting sleeve 62; when the antenna is in an upright state, one end of the limiting shaft 63 is inserted into the positioning hole 212, thereby limiting the rotation of the rotating seat 2, and thus making the support rod 4 always maintain an upright state;

[0059] When switching from the upright state to the inverted state, the handle 65 is pulled out, driving the limiting shaft 63 to move away from the positioning hole 212, and the entire limiting shaft 63 will be separated from the positioning hole 212, no longer restricting the rotation of the rotating base 2, and the spring 64 will be in compression.

[0060] In some possible implementations, the limiting shaft 63 includes a shaft body connected to the handle 65 at one end, and an annular convex portion sleeved on the outside of the shaft body; a limiting plate is arranged in the limiting sleeve 62 and on the side of the annular convex portion close to the handle 65, and the limiting plate cooperates with the annular convex portion to form a chamber for installing the spring 64, and the two ends of the spring 64 are respectively connected to the limiting plate and the annular convex portion; the limiting plate is arranged on the side of the annular convex portion away from the handle 65; the end of the shaft body away from the spring 64 cooperates with the positioning hole 212; the end of the shaft body away from the positioning hole 212 passes through the limiting plate and is screwed to the handle 65;

[0061] When the antenna is in an upright position, the spring 64 is sleeved in the chamber and is in an initial state or a compressed state, and the end of the shaft body away from the handle 65 will be located in the positioning hole 212. At this time, the plug block of the handle 65 is plugged into the socket; preferably, when the antenna is in an upright position, the spring 64 is in a compressed state.

[0062] In some possible embodiments, the rotating seat 2 includes two groups of crank connecting arms 21 arranged in parallel and having arc-shaped openings, and a connecting plate 22 used to connect the two groups of crank connecting arms 21 and cooperate with the two groups of crank connecting arms 21 to form a mounting cavity; one group of crank connecting arms 21 is provided with a positioning hole 212, and the other group of crank connecting arms 21 is provided with an avoidance groove 211 coaxial with the positioning hole 212; the end of the hinged portion 12 away from the chassis 11 is located in the mounting cavity and is hinged to the crank connecting arm 21 through the rotating shaft 3 to achieve rotation;

[0063] Specifically, the crank connecting arm 21 includes a connecting arm connected to the connecting plate 22 and hingedly cooperated with the hinged portion 12, and an arc arm connected to one end of the connecting arm away from the antenna and used in conjunction with the upright locking piece 6; an arc opening is arranged on the arc arm, and the arc arm is hingedly cooperated with the vibration-damping support shaft 5; when the antenna is in an upright state, the connecting arm is arranged along the Z-axis direction, and the arc opening is arranged on a side close to the inverted locking piece 7; one end of the arc arm away from the connecting arm is hingedly connected to the vibration-damping support shaft 5.

[0064] One end of the limiting sleeve 62 passes through the avoidance groove 211, is sleeved in the ear seat 61 and forms a whole with the ear seat 61;

[0065] A protrusion is provided on the arc-shaped opening of the arc-shaped arm close to the limiting shaft 63 and away from the handle, and the positioning hole 212 is provided on the protrusion.

[0066] In some possible implementations, the support rod 4 is a hollow structure and is threadedly engaged with the rotating seat 2. A cable 100 having one end connected to the antenna is disposed in the hollow structure, and the other end of the cable 100 passes through the rotating seat 2, the hinged portion 12, and the chassis 11 in sequence.

[0067] One end of the cable 100 passes through the chassis 11, the hinge 12, the rotating seat 2, the support rod 4 and is connected to the antenna located on the top of the support rod 4;

[0068] In order to effectively seal the cable 100, two groups of rubber blocks 8 are sleeved on the outside of the cable 100, an upper pressure plate 9 is provided at the bottom of the support rod 4 for use with one group of rubber blocks 8 and is located below the rubber block 8, and a lower pressure plate 10 is provided at the bottom of the chassis 11 for use with the rubber block 8 at the other end; concave cavities for use with the rubber block 8 are provided at the bottom of the support rod 4 and the chassis 11 respectively; the inner diameter of the rubber block 8 is slightly larger than the outer diameter of the cable 100.

[0069] In some possible implementations, the locking assembly further includes two sets of bosses 121 disposed on the hinge portion 12 and used in conjunction with the connecting plate 22;

[0070] One set of bosses 121 is arranged on the side of the hinged portion 12 close to the inverted lock 7, and the other set of bosses 121 is arranged on the side away from the inverted lock 7; through the cooperation between the two sets of bosses 121 and the connecting plate 22, the rotating seat 2 can be rotated within the range of 0°-90°;

[0071] The connecting plate 22 is L-shaped, and includes a top plate for mounting the support rod 4 and abutting against a group of bosses 121 when the antenna is in a fallen state, and a vertical plate connected to the top plate and abutting against another group of bosses 121 when the antenna is in an upright state;

[0072] The vertical plate is arranged on a side of the connecting arm away from the avoidance groove 211 ; a connecting sleeve which is threadedly connected with the support rod 4 is arranged on the top plate.

[0073] An external thread is provided at the bottom of the support rod 4, and an internal thread is provided in the connecting sleeve, and the two are screwed together to achieve connection. An end cap is provided at the bottom of the support rod 4; a channel connected to the hollow structure is provided on the end cap; a concave cavity is provided at the bottom of the end cap, and a rubber block 8 is installed in the concave cavity and compressed by the upper pressing plate 9, so that the rubber block 8 is squeezed and deformed to fill the concave cavity, thereby sealing the cable 100; the upper pressing plate 9 is connected to the end cap by screws and is located between the end cap and the connecting plate 22;

[0074] Similarly, a cavity is provided on the chassis 11, and a group of rubber blocks 8 will be installed in the cavity. The rubber blocks 8 are compressed by the lower pressing plate 10, so that the rubber blocks 8 are squeezed and deformed to fill the cavity and seal the cable 100; the lower pressing plate 10 is connected to the chassis 11 by screws;

[0075] Furthermore, the concave cavity is a conical structure, and the rubber block 8 is a conical structure; a drainage hole is also provided on the base 1 to prevent water accumulation.

[0076] In some possible implementations, the vibration-damping support shaft 5 is an elastic vibration-damping device in the prior art, which is composed of two groups and symmetrically arranged, and is respectively connected to two groups of crank connecting arms 21, so that the rotating seat 2 is evenly stressed. The vibration-damping support shaft can reinforce the entire device, and the bottom support is more stable, which can reinforce the base 1 during vibration impact.

[0077] Specifically, the vibration-damping support shaft 5 includes an articulated shaft 51 hinged to the base 1, a connecting shaft sleeve 53 sleeved on the outside of the articulated shaft 51 and articulated to the rotating seat 2, and a compression spring 52 sleeved on the outside of the articulated shaft 51 and partially extending into the connecting shaft sleeve 53; the articulated shaft 51 and the connecting shaft sleeve 53 are coaxially slidably matched; a spring installation cavity is formed between the articulated shaft 51 and the connecting shaft sleeve 53, the compression spring 52 is located in the spring installation cavity and its two ends are respectively connected to the connecting shaft sleeve 53 and the articulated shaft 51.

[0078] When the compression spring 52 is in an upright state, its pre-compression force generates a torque to prevent the support rod 4 from rotating; when the support rod 4 rotates 45° from a lying state or an upright state, the compression amount of the compression spring 52 is the largest. After rotating 45°, the force generated by the compression spring 52 changes from preventing rotation to promoting rotation until it rotates 90°; when the support rod 4 is in an upright state or a lying state, the α formed at this time will be 45°. Since α is consistent, the compression amount of the compression spring 52 can be kept consistent.

[0079] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
