Description

Technical Field

[0001] The utility model belongs to the relevant technical field of automobile parts, and particularly relates to an automobile switch with a button blocking structure. Background Art

[0002] The automobile switch in the prior art is usually composed of a button, a housing, a micro switch, a circuit board, a bottom cover, etc. The circuit board is arranged on the bottom cover, the bottom cover is arranged in the housing, the micro switch is arranged on the circuit board, and the button is arranged on the surface of the housing for pressing the micro switch. However, according to the different configurations of the automobile, some buttons on the existing automobiles are functional and some are non-functional. For the functional buttons, the micro switch is generally welded directly on the circuit board, and a conductive rubber is arranged on the circuit board. The upper button is pressed down to drive the conductive rubber to press down and drive the micro switch below to work, so as to realize the corresponding function. For example, the patent number is 201220065239.3, and the patent name is: Automobile electric window switch, which includes a housing composed of an upper cover and a lower cover and a circuit board arranged in the housing, the upper cover is provided with a button assembly, the housing is provided with a conductive rubber, and the conductive rubber is provided in the housing. An elastic part that cooperates with the button assembly is arranged on the rubber, and the edge of the conductive rubber completely covers the circuit board, and the circuit board is interference-fitted with the shell through the conductive rubber. With such a structural arrangement, if the automobile switch needs to be changed from a function button (pressable) to a blocking cover (non-pressable), the upper structure cannot be realized, so the mold can only be re-opened, which is not only troublesome in process but also high in cost, and cannot meet the needs of different customers, because the later function buttons cannot be directly changed into a non-functional and non-pressable mode. Therefore, the existing automobile switches of this type cannot meet the needs of customers for arbitrary replacement of functional or non-functional buttons. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figure 1-7As shown, the present embodiment discloses a car switch with a button blocking structure, comprising a housing 1 and a circuit board 2 arranged in the housing 1, a conductive rubber 4 located in the housing 1 is arranged above the circuit board 2, an elastic body 5 cooperating with the button assembly 3 is arranged on the conductive rubber 4, the housing 1 is composed of a buckle cover 101, a housing seat 102 and a bottom cover 103, the button assembly 3 is arranged on the buckle cover 101, the elastic body 5 comprises an isosceles trapezoidal portion 501 and a cylindrical portion 502 formed in one piece, the isosceles trapezoidal portion 501 is located below the cylindrical portion 502, and at least one mounting groove 11 is arranged at the front end of the housing seat 102, and a movably inserted connector 11 is provided in each mounting groove 11. There is a blocking cap 6, which is used to be movably sleeved on the outside of the elastomer 5, and when the blocking cap 6 is sleeved on the elastomer 5, it is ensured that the bottom end face of the blocking cap 6 is pressed against the upper surface of the conductive rubber 4, and the top of the blocking cap 6 is pressed against the bottom of the corresponding button assembly 3, and at this time the button assembly 3 is limited to ensure that the button assembly 3 cannot be pressed down. In order to avoid deformation, the blocking cap 6 is made of hard plastic or metal products to ensure that the blocking cap 6 structure has a certain strength. In this embodiment, in order to facilitate the removal of the blocking cap 6, after the blocking cap 6 is inserted into the installation groove 11, a part of the installation groove 11 needs to be exposed, so that it is convenient to quickly grab the blocking cap 6 later and take the blocking cap 6 out of the installation groove 11.

[0026] It should be noted that the elastomer 5 is usually linked with the elastomer 5 through a button assembly and a top rod under the button assembly, and a conductive spring sheet is provided on the circuit board 2 to cooperate with the elastomer 5 to achieve linkage as a micro switch, which belongs to conventional technology in this field and will not be described in detail here.

[0027] Preferably, in order to strengthen the pressing force with the conductive rubber and better fix the position of the elastomer embedded in the plugging cap, the bottom end face of the plugging cap 6 is provided with one or more cylindrical protrusions 7 in a ring shape. The added cylindrical protrusions 7 can further strengthen the pressing force with the conductive rubber and better fix the position of the elastomer embedded in the plugging cap.

[0028] Preferably, an inner hole 8 is provided in the plugging cap 6 , and the diameter of the inner hole 8 is equal to the length of the lower base of the isosceles trapezoidal portion 501 and ensures that the elastic body 5 can be fully inserted into the inner hole 8 .

[0029] Preferably, to improve the waterproof effect, the conductive rubber 4 is provided with downward insulating folded edges 401 around it, and the circuit board 2 is placed at the bottom of the conductive rubber 4 and is interference fit with the inner side of the shell seat 102 through the insulating folded edges 401. By adopting interference fit between the conductive rubber 4 and the shell seat 102, a waterproof effect can be further achieved, and the circuit board can also be fixed.

[0030] Preferably, in order to facilitate installation, a partition 1021 is provided in the shell base 102, and more than one button hole 9 is provided on the partition, and a button assembly 3 is provided in each button hole 9, the buckle cover 101 is buckled on the top of the shell base 102, and the bottom cover 103 is buckled on the bottom of the shell base 102, and an output socket 10 electrically connected to the circuit board 2 is plugged on the bottom cover 103, and the pins on the output socket 10 can be directly plugged into the corresponding socket of the bicycle to power the device, and a plug-in connection is adopted to facilitate the later disassembly of the device.

[0031] The present structure arranges a plurality of blocking caps 6 at the front end of the shell seat 102. When not in use, the blocking caps 6 are inserted into the installation grooves 11. When a certain button needs to be changed from a functional button (i.e., pressable) to a non-functional button (i.e., cannot be pressed), it is only necessary to remove the blocking caps 6 and put the blocking caps 6 on the two elastic bodies 5 under the corresponding button assembly 3. Then, the button assembly 3 is pressed onto the blocking caps 6 to ensure that the bottom of the blocking caps 6 is pressed tightly against the top of the conductive rubber 4 so that both the upper and lower surfaces of the blocking caps 6 are pressed tightly, making it impossible for the button assembly 3 to be pressed down, thereby losing the function of the micro switch corresponding to the circuit board below being pressed down to start the function, and making it lose the function of the functional button. Therefore, the present structure can quickly perform a free replacement mode of functional or non-functional buttons without the need for additional mold design, and is convenient for replacement according to requirements, making it more in line with the diversified purposes of users.

By providing the elastic strip 601 above the plugging cap 6, it is convenient to grab and remove the plugging cap 6 from the installation groove 11 at a later time.
