[0027] Please also read Figures 1 to 5 The coaxial bracket, coaxial connector installation assembly and vehicle provided by the utility model are now described. The coaxial bracket is used to install the coaxial connector 4. The bottom of the coaxial connector 4 is provided with a horizontally extending installation slide 41. The coaxial bracket includes a mounting plate 1 connected to the vehicle body sheet metal. The upper part of the mounting plate 1 is provided with a mounting slide bar 2 that slidably cooperates with the mounting slide 41. The mounting plate 1 is a conductive material component.

[0028] Compared with the prior art, the coaxial bracket provided in the present embodiment has a mounting slide bar 2 on the mounting plate 1 that can cooperate with the mounting groove 41 at the bottom of the coaxial connector 4 to achieve reliable installation of the coaxial connector 4. The mounting plate 1 is made of conductive material. The static electricity on the coaxial connector 4 can be smoothly conducted to the vehicle body sheet metal through the mounting plate 1, thereby achieving effective grounding of the coaxial line, avoiding the problem of video signal interference caused by static electricity on the coaxial line, eliminating screen flickering, avoiding signal attenuation, and ensuring normal use of the equipment.

[0029] In this embodiment, on the basis of the sliding fit between the installation slot 41 and the installation slide bar 2, the installation slot 41 can be set to be open at one end and closed at the other end, and the closed end of the installation slot 41 is used to abut against the sliding end of the installation slide bar 2 that first slides into the installation slot 41 to achieve the limit of the installation slot 41 and the installation slide bar 2, thereby ensuring the reliable installation of the coaxial connector 4 on the coaxial bracket. At the same time, the installation slot 41 and the installation slide bar 2 are set to a transition fit or tight fit structure, so as to ensure the locking effect of the coaxial connector 4 between the coaxial brackets after installation.

[0030] In some possible implementations, the above-mentioned characteristic mounting plate 1 is used as follows Figure 1 and Figure 2 See the structure shown. Figure 1 and Figure 2 The mounting plate 1 is connected to the vehicle body sheet metal through a connector 3, and the connector 3 is a conductive material component.

[0031] In this embodiment, the mounting plate 1 is connected to the vehicle body plate via the connector 3. The connector 3 is a conductive material component, which meets the grounding requirements of the coaxial line, simplifies the installation process of the coaxial connector 4, facilitates the installation and disassembly of the mounting plate 1, and helps to improve the assembly efficiency of the structure.

[0032] A projection nut is pre-welded under the body sheet metal, and the connector 3 penetrates the mounting plate 1 and is threadedly connected to the projection nut, so that the mounting plate 1 is reliably fixed to the body sheet metal. The connector 3 can be a connecting member with external threads such as bolts and screws.

[0033] Specifically, the connector 3 uses a grounding bolt, which has good conductor performance, and is convenient for cooperating with the mounting plate 1 to achieve effective grounding of the coaxial line, avoiding video interference caused by static electricity. Furthermore, the outer periphery of the connector 3 is also sleeved with an elastic pad 31 and a washer 32, and the elastic pad 31 is located above the washer 32, which has good anti-loosening and vibration reduction performance, ensuring the reliability of the connection.

[0034] Based on the same inventive concept, an embodiment of the present application also provides a coaxial connector installation assembly, including a coaxial bracket and a coaxial connector 4 installed on the coaxial bracket, the installation groove 41 includes an opening cavity 42 and an inner bottom cavity 43 connected to the top of the opening cavity 42, the opening cavity 42 and the inner bottom cavity 43 are arranged through the same side wall of the coaxial connector 4, and the inner cavity width of the inner bottom cavity 43 is greater than the inner cavity width of the opening cavity 42.

[0035] The mounting slide bar 2 includes a slide bar 21 connected to the top of the mounting plate 1 and a slide plate 22 arranged above the slide bar 21. The two side edges of the slide plate 22 protrude outward from the two side walls of the slide bar 21. The slide plate 22 is slidably connected to the inner bottom cavity 43, and the slide bar 21 is located in the open cavity 42.

[0036] In this embodiment, for the convenience of description, the extension direction of the installation slide bar 2 is defined as the length direction, and the direction perpendicular to the length direction is defined as the width direction. The opening cavity 42 and the inner bottom cavity 43 are respectively set through the same side wall of the coaxial connector 4, and the installation slide bar 2 enters the installation slide groove 41 from this end and gradually slides to the closed end of the installation slide groove 41, realizing the cooperation between the installation slide groove 41 and the installation slide bar 2, and the end of the slide bar 21 that first contacts the slide groove and slides in is defined as the sliding end.

[0037] The installation groove 41 is in the form of a combination of an open cavity 42 and an inner bottom cavity 43, and the installation slide bar 2 is in the form of a combination of a sliding bar 21 and a sliding plate 22. The width of the sliding bar 21 is smaller than the width of the sliding plate 22. The sliding plate 22 and the inner bottom cavity 43 slide together to achieve effective assembly between the installation groove 41 and the installation slide bar 2. The width of the sliding plate 22 is greater than the width of the open cavity 42, which can effectively prevent the installation slide bar 2 from falling off from the installation groove 41, thereby preventing the coaxial connector 4 from detaching from the top of the coaxial bracket.

[0038] Based on the above structure, see Figure 3 The two sides of the sliding bar 21 are respectively provided with matching parts 23, which are arranged away from the sliding end of the sliding bar 21, and the matching parts 23 are slidably connected in the opening cavity 42. The matching parts 23 on both sides of the sliding bar 21 are respectively arranged away from the sliding end of the installation sliding bar 2, and the matching parts 23 can be slidably matched with the opening cavity 42, effectively guiding the installation position of the coaxial connector 4, facilitating the improvement of assembly efficiency, simplifying the assembly process, and ensuring the stable and reliable installation of the coaxial connector 4.

[0039] In some possible implementations, the above-mentioned coaxial connector 4 and mounting plate 1 are used as follows: Figures 3 to 5 See the structure shown. Figures 3 to 5 The bottom of the coaxial connector 4 is also provided with a clamping block 44 located outside the closed end of the mounting slot 41 , and the mounting plate 1 is provided with a clamping hole 11 that is engaged with the clamping block 44 .

[0040] In this embodiment, on the basis of utilizing the sliding cooperation between the installation slide bar 2 and the installation slide groove 41, a clamping block 44 is also provided on the coaxial connector 4 to engage with the clamping hole 11 on the mounting plate 1. The position locking of the coaxial connector 4 during the sliding process is achieved by utilizing the cooperation between the clamping block 44 and the clamping hole 11, thereby ensuring the reliability of the installation of the coaxial connector 4.

[0041] In some embodiments, the feature card block 44 may be used as follows: Figure 4 and Figure 5 See the structure shown. Figure 4 and Figure 5 The block 44 has an introduction surface 45 on one side adjacent to the mounting groove 41. The introduction surface 45 extends obliquely from bottom to top toward the side close to the mounting groove 41 and is used to guide the block 44 into the hole 11. The hole 11 is a rectangular hole. The side wall of the hole 11 away from the mounting slide bar 2 is used to abut and cooperate with the end face of the block 44.

[0042] In this embodiment, the side of the block 44 adjacent to the mounting groove 41, that is, the side of the block 44 close to the closed end of the mounting groove 41, is effectively locked between the mounting groove 41 and the mounting slide 2 through the snap-fitting cooperation between the block 44 and the snap hole 11, thereby reliably installing the coaxial connector 4 above the coaxial bracket.

[0043] On this basis, the block 44 has an introduction surface 45 arranged near the closed end of the mounting groove 41. As the mounting slide 2 gradually enters the mounting groove 41, the guide surface of the block 44 gradually contacts the side wall of the card hole 11 close to the mounting slide 2 until the block 44 completely enters the card hole 11, thereby realizing the locking of the relative position between the coaxial connector 4 and the mounting plate 1.

[0044] In some possible implementations, the above-mentioned characteristic mounting plate 1 is used as follows Figure 3 See the structure shown. Figure 3 A side baffle 12 is provided on one side of the mounting plate 1 away from the clamping hole 11 . The side baffle 12 extends perpendicularly to the direction of the mounting slide bar 2 . The side baffle 12 protrudes upward from the top surface of the mounting slide bar 2 .

[0045] In some embodiments, the above-mentioned characteristic mounting plate 1 can be used as follows Figure 3 See the structure shown. Figure 3 The mounting plate 1 is provided with a limiting boss 13 adjacent to the side baffle 12. The limiting boss 13 protrudes upward from the mounting plate 1 and is used to abut against the end face of the coaxial connector 4 to limit the coaxial connector 4. When the coaxial connector 4 is mounted on the mounting plate 1, the side baffle 12 can facilitate the operator's hand holding, and also has a certain limiting function, which can limit the position of the corresponding end face of the coaxial connector 4.

[0046] On this basis, a limiting boss 13 is also provided adjacent to the mounting plate 1 and the side baffle 12. The height of the limiting boss 13 is lower than the height of the side baffle 12, and it can contact with the end face of the coaxial connector 4 to achieve a reliable limiting effect. At this time, the end face of the coaxial connector 4 is spaced a certain distance from the side baffle 12, and the limiting boss 13 plays a good limiting role, which facilitates the operation of the operator.

[0047] In some embodiments, see Figure 1 to Figure 2 The coaxial connector installation assembly includes two coaxial connectors 4. Two mounting slide bars 2 and two card holes 11 are respectively provided on the mounting plate 1, and the two mounting slide bars 2 are arranged in parallel.

[0048] The coaxial bracket is provided with two coaxial connectors 4, which can effectively reduce the space occupied and facilitate the reasonable arrangement of the space. Corresponding to the two coaxial connectors 4, two mounting slide bars 2 and two card holes 11 are also provided respectively to meet the installation requirements of the two coaxial connectors 4.

[0049] The two mounting slide bars 2 are arranged in parallel to reduce the space occupied by the coaxial connector 4 and realize a reasonable arrangement of the structure. One or more connectors 3 may be provided. If one connector 3 is provided, it may be provided between the two mounting slide bars 2 to ensure the effective connection between the mounting plate 1 and the vehicle body sheet metal and improve the reliability of the connection.

[0050] Compared with the prior art, the coaxial bracket provided in this embodiment realizes effective positioning of the coaxial bracket and the coaxial connector 4 in the up and down directions by slidingly cooperating the sliding plate 22 of the mounting slide bar 2 with the inner bottom cavity 43 of the mounting slide groove 41, thereby realizing reliable installation of the coaxial connector 4. The static electricity on the coaxial connector 4 can be smoothly conducted to the vehicle body sheet metal through the mounting plate 1, thereby realizing effective grounding of the coaxial line, avoiding the problem of video signal interference caused by static electricity on the coaxial line, and ensuring the normal use of the equipment.

[0051] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, which includes a coaxial connector installation assembly. The vehicle uses a mounting seat to achieve reliable installation of the coaxial connector 4. The static electricity on the coaxial connector 4 can be smoothly conducted to the vehicle body sheet metal through the mounting plate 1, thereby achieving effective grounding of the coaxial line, avoiding the video signal interference problem caused by static electricity on the coaxial line, and ensuring the normal use of the equipment.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
