And the function of losing the switch can be realized without changing the internal structure of the switch.

Description

Technical Field

[0001] The utility model relates to a multifunctional switch with a push rod on a car, in particular to a multifunctional switch with a switch button and a blocking cover having completely the same assembly structure, except that a positioning structure is added to the blocking cover to make the blocking cover fixed. Background Art

[0002] The automotive market is changing rapidly, and the market for certain specific models is all over the world, but the functional configuration of the whole vehicle is not exactly the same in all parts of the world. In order to meet the functional requirements of different configurations, reduce the production cost of the whole vehicle and improve interchangeability, the switch button realizes the on and off functions of the switch through the conduction of the push rod. When the switch function is not needed, due to different vehicle configurations, the switch button and another plug cover are switched, and the switch needs to be disassembled and the push rod removed. In this way, the switch fails due to wrong installation or missing installation during reassembly. Summary of the invention

[0003] The utility model aims to provide a multifunctional switch with a push rod, which can realize the switching of switch keys or switching of unnecessary switch functions without taking out the internal push rod.

[0004] To this end, the technical solution of the utility model is: a multifunctional switch with a push rod, including a switch button, a push rod, a shell, a conductive rubber, a circuit board, and a base, the circuit board is fixed on the base, the base is installed at the lower part of the shell, the switch button is sleeved on the shell, the push rod is installed in the shell, a pressing protrusion is provided in the switch button, and the pressing protrusion contacts the top of the push rod. It is characterized in that: a blocking cover is also separately configured, a pressing protrusion is provided on the upper end surface of the blocking cover, and a positioning protrusion is also provided on the upper end surface of the blocking cover; when the blocking cover is to be installed, the switch button is removed and the blocking cover is directly sleeved on the shell, the positioning protrusion in the blocking cover contacts the end surface of the shell, so that the blocking cover does not contact the push rod.

[0005] Furthermore, there are two positioning protrusions in the plugging cover, which are arranged in a direction rotated 90 degrees relative to the pressing protrusion. The two positioning protrusions further ensure that the plugging cover is reliably positioned on the shell.

[0006] Furthermore, except for the setting structure of the positioning protrusion in the blocking cover, the other structures of the blocking cover are the same as the switch button. This setting is for ease of manufacturing.

[0007] The beneficial effect of the utility model is that on the basis of the existing switch button, push rod, shell, conductive rubber, circuit board and base, a plug cover with a positioning protrusion is separately configured. After installation, the positioning protrusion in the plug cover contacts the cross section of the shell, and the positioning protrusion contacts the end face of the shell, so that the plug cover does not contact the push rod, and the switch function can be lost without removing the push rod and changing the internal structure of the switch.

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] like Figure 1-Figure 4 As shown, a multifunctional switch with a push rod comprises a switch button 6, a push rod 5, a shell 4, a conductive rubber 3, a circuit board 2, and a base 1. The circuit board 2 is fixed on the base 1, the base 1 is installed at the lower part of the shell 4, the switch button 6 is sleeved on the shell 4, the push rod 5 is installed in the shell 4, a pressing protrusion 7 is provided in the switch button, and the pressing protrusion 7 contacts the top of the push rod 5, and a blocking cover 8 is also separately configured, the upper end surface of the blocking cover is provided with a pressing protrusion 7, and the upper end surface of the blocking cover is also provided with a positioning protrusion 9; when the blocking cover 8 is to be installed, the switch button 6 is removed, and the blocking cover is directly sleeved on the shell, and the positioning protrusion 9 in the blocking cover contacts the end surface of the shell 4, so that the blocking cover does not contact the push rod.

[0015] like Figure 4 As shown, there are two positioning protrusions 9 in the plugging cover 8, which are arranged in a direction rotated 90 degrees relative to the pressing protrusion. The two positioning protrusions further ensure that the plugging cover is reliably positioned on the housing.

[0016] like Figure 3 , Figure 4 As shown, except for the positioning protrusion 9 in the blocking cover, the other structures of the blocking cover are the same as the switch button. This arrangement is for ease of manufacturing; in the utility model, after the positioning protrusion 9 in the blocking cover is removed, it can become a switch button.
