detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a plan view of a specific embodiment of a roof antenna mount according to the present invention; FIG. 2 is a view taken along line A-A of FIG. 1; and FIG. 3 is a view taken along line B-B of FIG.

In a specific embodiment, the roof antenna mount provided by the present invention is mainly composed of two parts of the base 1 and the top plate 2.

Wherein, the base 1 has a hollow box structure, has a square shape in cross section, and the bottom plate 1-1 is opposite The side wall 1-2 is inwardly retracted by a certain distance in the longitudinal direction, and has an inwardly concave shape. The top plate 2 is located at the top of the base 1 and has a rectangular shape with a size larger than the cross section of the base 1, and its periphery is outward with respect to the base 1. Extend to form a snap edge.

An antenna mounting screw socket 3 is fixed on the top of the top plate 2, and the screw socket 3 is a flat rectangular hollow profile which is transversely welded to the top of the top plate 2 in the width direction of the vehicle body, and two threads on each screw socket 3 The holes correspond to the threaded holes on the top plate 2, and are symmetrically distributed in the left-right direction of the vehicle body width for fixing the antenna by screws or bolts, and providing corresponding connection positions for the screws or bolts.

As shown in the figure, the top of the top plate 2 is further provided with a circumferentially closed protrusion 4, which may be integrated with the top plate 2, or may be separately processed and assembled together, and the inner area enclosed by the protrusion 4 is In the roof antenna mounting area, the roof antenna mounting area is rectangular in plan view, and the threaded hole on the top plate 2 is located inside the roof antenna mounting area.

Since the roof antenna 5 is installed, the cable 6 needs to be introduced from the roof to the interior of the vehicle body to establish a power and communication connection. Therefore, the roof antenna mount is further provided with a cable through hole 7 in the structure. Upper, the cable through hole 7 extends longitudinally through the base 1 and the top plate 2.

Specifically, the cable through hole 7 is formed by a circular sleeve fixed to the inside of the base, which is located at a center position which is biased toward the rear side in the front-rear direction of the vehicle body.

In order to further improve the thermal insulation performance of the antenna mounting portion, the inner cavity of the base may be filled with a heat insulating material (not shown), such as a foaming agent, etc.; and, in order to improve the structural strength of the base, it may also be inside the base. Design corresponding ribs and other structures to improve the strength of the vehicle body at the antenna installation site under the premise of meeting the weight reduction requirements.

Although the base 1 and the top plate 2 are designed to have a rectangular shape, they are not limited thereto. According to the layout and needs of the roof mounting space, the base 1 and the top plate can also be designed to be circular, semi-circular, elliptical, triangular, trapezoidal, polygonal, etc. shape.

In addition, the form of the screw seat 3 is not limited to the strip profile, but may also be a nut welded to the top of the top plate 2, or a connecting block with a threaded hole, etc., and even the screw socket can be omitted. Use a nut to lock the bolt from the inside.

For conventional cables, especially bundled cables, the cable through-holes shown in the figure can basically meet the routing requirements of the antenna. However, considering that in some special cases, the cable of the antenna may be relatively scattered, for this, a plurality of cable through holes 7 may be designed for respectively passing through different positions and different types. The antenna and the cable through hole 7 do not need to completely depend on the sleeve. For the sake of simplicity, the sleeve can be omitted, and the cable can be directly passed through the through hole on the top plate, the inside of the base, and the base plate directly from top to bottom. The upper through hole is introduced into the interior of the vehicle body, but it is an ideal solution because the sleeve can protect the cable passing through the inside thereof.

In summary, the above is only a preferred embodiment of the roof antenna mount of the present invention, and is not limited thereto. On this basis, a targeted adjustment can be made according to actual needs, thereby obtaining different implementation manners. Since there are many ways to implement, there is no longer an example here.

The snap edge of the top plate 2 is supported on the top of the vehicle body, and the bottom of the roof antenna 5 is fixed by screws 9 (or bolts). The roof antenna installation area is fully welded to the top of the vehicle body, and a ring-shaped annular region is formed between the periphery and the protrusion 4. The inside of the annular area is filled with the sealant 10, and the bottom of the roof antenna 5 is thicker than the protrusion 4. Therefore, the top of the sealant 10 is beveled, and the cable 6 of the roof antenna 5 is introduced through the cable through hole 7 from the roof to the inside of the vehicle body to establish a power and communication connection.

Since the mounting seat has a hollow box structure, the antenna mounting screw seat 3 is welded in the box body, which ensures the antenna installation strength and reduces the overall weight of the mounting seat, and satisfies the concept of the lightweight design of the EMU, and the mounting seat The method of settlement is installed on the roof of the EMU, which reduces the installation height of the roof antenna 5, improves the flatness of the car body, and satisfies the requirements of the streamlined design of the EMU.

In addition, the mounting surface of the mounting seat is provided with a circumferential ring protrusion 4, and the roof antenna 5 can further improve the airtight performance of the vehicle by applying the sealing glue 10 after installation.
