Description

Technical Field

[0001] This utility model relates to wireless communication in automotive electronics, specifically to an on-board amplifier and its connection structure. Background Technology

[0002] Currently, vehicles are equipped with various in-vehicle electronic devices, such as radio receivers, touch screen displays, navigation devices, and mobile phones. These in-vehicle electronic devices are connected to the car antenna via cables. The car antenna can receive signals from the outside world and send signals to these in-vehicle electronic devices. However, due to the long distance between the car antenna and the in-vehicle electronic devices, signal loss can occur. Therefore, different signal amplifiers are usually required to alleviate the signal loss problem.

[0003] Amplifiers are typically mounted on the inner sheet metal of the tailgate. Since the tailgate is constructed from at least two layers of sheet metal (inner and outer panels), during manufacturing, weld nuts or rivet nuts are first welded to the inner sheet metal. Then, the inner and outer sheet metal are spot-welded together. Finally, during vehicle installation, the amplifier is secured and grounded using nuts. Due to the amplifier's need for grounding with the vehicle body, it is currently secured using bolts and weld nuts or rivet nuts tightened onto the vehicle body. Figure 1a , 1b As shown in 2a and 2b, this increases the process requirements for the car body, requiring the addition of welding or riveting processes. However, using welding or riveting processes can cause the sheet metal at the mounting point to deform due to heat, or the engagement force between the nut and the sheet metal after riveting may not meet the requirements.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] like Figure 3 , 4 The vehicle-mounted amplifier shown includes an amplifier body 1 and a connecting assembly. Specifically:

[0040] The amplifier body 1 includes a housing and electronic components, with the electronic components housed within the housing. The housing includes a base 10 and a top cover 11, which together enclose a space for housing the electronic components. The electronic components include a PCB board 20, a Fakra connector 21, an MQS module 22, etc.

[0041] In this embodiment: one end of the base 10 has a receiving portion 100 extending downward therefrom, the receiving portion 100 is hollow, and one end of the top cover 11 has a pressing portion 110.

[0042] The connecting components include a positioning element 30 and fasteners, both of which are connected to the housing of the amplifier body 1. Specifically:

[0043] The positioning element is used to fix the amplifier body 1 to the sheet metal, and it is connected to the bottom of the base 10 of the housing of the amplifier body 1. In this embodiment, the positioning element is a hook 30, and the opening of the hook 30 faces the fastener.

[0044] Fasteners are used to secure the amplifier body 1 to the sheet metal and are connected to one end of the housing of the amplifier body 1. In this embodiment, the fastener includes a rotating component and a fastening washer 311. Wherein:

[0045] The rotating component is a screw 310, which can be connected to a fastening washer 311 via threads to drive its rotation. The screw 310 is connected to the housing of the amplifier body 1, specifically: the screw 310 passes through the clamping part 110 of the upper cover 11, the fastening washer 311, and the receiving part 100 of the base 10 in sequence.

[0046] The fastening washer 311 is connected to the screw 310 and located within the receiving portion 100 of the base 10, which restricts the rotation angle of the fastening washer 31. The fastening washer 311 has fastening portions 3110, which can be one or more. In the illustration, the fastening portions 3110 are located at the four corners of the fastening washer 311, and the four fastening portions 3110 can achieve stable clamping. For example, the fastening washer 311 can be a square washer, with the four corners forming the fastening portions 3110. Preferably, the fastening portions 3110 have pointed tips, and these tips extend into the sheet metal in the tightened state. That is, the entire fastening washer 311 is not a flat washer; its four fastening portions 3110 are curved upwards, providing better clamping force.

[0047] In this embodiment, screws 310 and fasteners are respectively connected to both ends of the amplifier body 1, so that the vehicle amplifier can be stably connected to the sheet metal.

[0048] The following details the connection structure of the vehicle amplifier, specifically the connection of the vehicle amplifier to sheet metal 4.

[0049] The sheet metal 4 has a first mounting hole 40 and a second mounting hole 41. In order to facilitate the cooperation with the hook 30 and the fastening washer 311, the first mounting hole 40 and the second mounting hole 41 are both square, i.e. square holes.

[0050] When the car amplifier is connected to the sheet metal: first align the hook 30 with the first mounting hole 40, and then hook its opening through the first mounting hole 40 onto the sheet metal 4, such as... Figure 5 , 6 As shown.

[0051] Next, the receiving portion 100 of the base 10 and the fastening pad 311 located therein are passed through the second mounting hole 41. The shape of the receiving portion 100 matches the shape of the second mounting hole 41, which can also prevent displacement after the amplifier body 1 is positioned. At this time, the four fastening portions 3110 of the fastening pad 311 correspond exactly to the four corners of the square second mounting hole 41. Figure 7 As shown.

[0052] Rotate screw 310 again, causing fastening washer 311 to rotate as well. At this time, the four fastening parts 3110 of fastening washer 311 are misaligned with the four corners of the square second mounting hole 41. The receiving part 100 restricts the rotation of fastening washer 311. Continue rotating screw 310, and fastening washer 311, unable to rotate, moves relative to screw 310, causing the four fastening parts 3110 of fastening washer 311 to finally abut against the lower surface of sheet metal 4, while the abutting part 110 of the upper cover 10 abuts against the upper surface of sheet metal 4, thereby clamping sheet metal 4 at the second mounting hole 42. Figure 8 As shown, complete the connection.

[0053] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
