Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive key signal detection technology, specifically to an automotive key signal strength testing device. Background Technology
[0002] In the existing technology, during the automobile production testing process, the testing of the car key signal generally requires manual handling of the key at different distances from the signal receiver, as well as placing a metal plate between the key and the signal receiver to observe whether the signal can be transmitted stably at different distances. This method is time-consuming and labor-intensive, and the test structure is not accurate, with a large error. Utility Model Content
[0003] The purpose of this invention is to provide a car key signal strength testing device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a car key signal strength testing device, including a supporting profile frame, a signal receiving device at the top of the supporting profile frame, a plurality of shielding aluminum plates at the lower end of the signal receiving device, a synchronous belt conveyor line at the lower end of the supporting profile frame, and an electrical control box on one side of the synchronous belt conveyor line.
[0005] In a further optimized configuration, the signal receiving device consists of a first signal receiver and a second signal receiver, which are stacked and arranged in the enclosed space at the top of the supporting profile frame.
[0006] In a further optimized configuration, the plurality of shielding aluminum plates are four in number, symmetrically arranged at the lower end of the signal receiving device, and connected to the supporting profile frame.
[0007] In a further optimized configuration, the lower part of the supporting profile frame is provided with four profile rods that are connected to the shielding aluminum plate.
[0008] In a further optimization, the shielding aluminum plate has a through hole in the middle that is slidably connected to the profile rod.
[0009] In a further optimization, the end face of the through hole is provided with a slider that is slidably connected to the profile rod, and a handle screw is provided on one side of the slider.
[0010] In a further optimization, each of the multiple shielding aluminum plates is equipped with a signal receiver on the side near the supporting profile frame. Beneficial effects
[0011] The car key signal strength testing device provided by this utility model is a servo motor driven synchronous belt conveyor line, which can transfer the key to any distance set by the program. The position of the blocking plates around the signal receiving end is adjustable, so as to carry out the signal testing of the car remote key. Attached Figure Description

Detailed Implementation
[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example
[0014] like Figure 1-4 As shown, a car key signal strength testing device includes a support frame 10, a signal receiving device 1 at the top of the support frame 10, a plurality of shielding aluminum plates 4 at the lower end of the signal receiving device 1, a synchronous belt conveyor line 2 at the lower end of the support frame 10, and an electrical control box 3 on one side of the synchronous belt conveyor line 2.
[0015] In this embodiment, the signal receiving device 1 consists of a first signal receiver 8 and a second signal receiver 9, which are stacked and arranged in the enclosed space at the top of the supporting profile frame 10.
[0016] The multiple shielding aluminum plates 4 are four in total, symmetrically arranged at the lower end of the signal receiving device 1, and connected to the supporting profile frame 10.
[0017] The lower part of the supporting profile frame 10 is provided with four profile rods that are connected to the shielding aluminum plate 4.
[0018] The shielding aluminum plate 4 has a through hole in the middle that is slidably connected to the profile rod.
[0019] The end face of the through hole is provided with a slider 6 that is slidably connected to the profile rod, and a handle screw 5 is provided on one side of the slider 6.
[0020] Signal receivers 7 are provided on one side of the multiple shielding aluminum plates 4 near the supporting profile frame 10.
[0021] The signal receiver is connected to the conveyor line number 2, with the signal receiver straddling the conveyor line, and the key can be moved to directly below the tester.
[0022] The shielding aluminum plate surrounds all four sides of the frame. There are four signal receivers, each of which is attached to the shielding aluminum plate. The bottom of the frame is open and there is no shielding aluminum plate. By loosening the handle screw and sliding the slider, the position of the shielding aluminum plate can be adjusted to change the spacing between the shielding plates. After adjusting the position, tighten the handle screw.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
