Technical Field

[0001] The utility model relates to the technical field of switches, and in particular to an installation structure of a base assembly and a micro switch. Background Art

[0002] Current car seat adjustment switches usually use micro switches to achieve electrical functions, and their operating feel is completely dependent on the micro switches.

[0003] The utility model patent with the existing application number of 201821474246.2 discloses a car seat adjustment switch, including a shell, a decorative panel is installed on the upper surface of the shell, and a plurality of decorative panel buckles are fixedly installed on the bottom surface of the decorative panel, and the decorative panel and the shell are fixed by the decorative panel buckles. The switch structure of the utility model adopts a pull-rod structure, which achieves the effects of crisp hand feeling, flexible return, no jamming, and flexible size, giving users a clearer experience, and the push rod is fixed by the metal fixing plate through the fixing plate buckle and the limit plate, which is convenient for rapid disassembly and assembly and stable fixation. The size of the button of the utility model can be flexibly adjusted, and the overall size of the button is required to be small. At the same time, a connecting rod is installed on the bottom surface of the button, and the connecting rod and the push rod are fixed by the buckle structure set at the lower end of the connecting rod. The installation is stable and firm, and the button is prevented from falling off.

[0004] However, the micro switch of this patent is soldered to the PCB board, and the PCB board is then integrated with connectors to achieve the functional output of the switch, which not only has a high overall cost, but also the assembly ultimately occupies a large space. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an installation structure which occupies a small assembly space, eliminates the need for connecting PCB boards and connectors through the direct connection between the micro switch and the base assembly, and realizes high current output in view of the deficiencies of the above-mentioned prior art.

[0006] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a mounting structure of a base assembly and a micro switch, comprising a base assembly, wherein a first metal insert is covered and fixed on the upper side of the base assembly, and the first metal insert is bent and distributed along the upper side of the base assembly, and a second metal insert is covered and fixed on the lower side of the base assembly, and the second metal insert is bent and distributed along the lower side of the base assembly, a plurality of first wiring points are arranged on the first metal insert, a second wiring point is arranged on the second metal insert in the same plane as the first wiring point, a micro switch is fixed above the first wiring point and the second wiring point, and the first metal insert and the second metal insert are electrically connected through the micro switch.

[0007] By adopting the above technical scheme, the first metal insert is bent and distributed on the upper side of the base assembly and is covered by the base assembly. By injection molding, the first metal insert and the second metal insert can be directly formed into a parallel structure and injected on the upper and lower sides of the base assembly. The first metal insert and the second metal insert are bent and distributed in order to install the pins of multiple micro switches in different positions, making welding more convenient, and the first wiring point and the second wiring point are set to the same plane to facilitate the fixed welding of the pins of the micro switch. By directly connecting the micro switch to the first metal insert and the second metal insert, the first metal insert and the second metal insert can be more adaptable to large current environments, and the PCB board and the connector are omitted, thereby saving costs. At the same time, the injection molding method can make the overall strength of the product higher and the service life of the product longer.

[0008] A mounting structure of a base assembly and a micro switch can be further configured as follows: a plurality of slots are provided on the lower side of the base assembly for partially exposing a second metal insert, and the base assembly is used to mount the micro switch on the lower side of the base assembly through the slots.

[0009] By adopting the above technical solution, the micro switch can be installed on the lower side of the base assembly through the slot hole, and the micro switch can be welded to the second metal insert through the slot hole to achieve electrical connection. The micro switch can be installed on both the upper and lower sides through the slot hole, making the installation of the product more convenient. At the same time, the slot hole can also have a heat dissipation effect, preventing the entire base assembly from overheating and causing damage to the micro switch, thereby increasing the reliability of the product.

[0010] A mounting structure of a base assembly and a micro switch can be further configured as follows: the first metal insert and the second metal insert are both metal inserts, and the micro switch is a toggle switch.

[0011] By adopting the above technical solution, the metal insert in the base assembly is directly stamped into a metal insert to replace the connector, thereby realizing functional output; after driving the micro switch, the first wiring point and the second wiring point are conductive and realize large current output, and the metal insert is directly covered and fixed by the base assembly through injection molding, which makes the overall height of the product lower and also eliminates the PCB board and the connector, thereby realizing optimization of the installation space and reducing parts and components to reduce production costs.

[0012] A mounting structure of a base assembly and a micro switch can be further configured as follows: the micro switch is laser welded above a first wiring point and a second wiring point respectively.

[0013] By adopting the above technical solution and through laser welding technology, since the first wiring point and the second wiring point are located in the same plane, only a more common multi-pin micro switch is needed to connect the first wiring point and the second wiring point, thereby realizing the conductivity of the first metal insert and the second metal insert and achieving large current output.

[0014] A mounting structure of a base assembly and a micro switch can be further configured as follows: a wiring seat is provided on the side of the base assembly opposite to the first metal insert and the second metal insert, a wiring slot is provided in the wiring seat, and wiring plugs are provided at the upper and lower ends of the wiring slot, which are respectively connected to the first metal insert and the second metal insert.

[0015] By adopting the above technical solution, the wiring plug is directly conductively connected to the first metal insert and the second metal insert. When the power is connected, the large current can be directly transmitted to the first metal insert and the second metal insert. At the same time, the first metal insert and the second metal insert are directly welded and fixed to the micro switch. At the same time, the wiring plug is arranged on the side of the first metal insert and the second metal insert so as not to interfere with the use of the first metal insert and the second metal insert. At the same time, it can also be directly connected to the wire trough, which not only directly eliminates the PCB board and saves parts but also reduces the installation space.

[0016] A mounting structure of a base assembly and a micro switch can be further configured as follows: the wiring plug includes a first wiring plug integrally arranged with the first metal insert and located at the upper end of a wiring slot, and a second wiring plug integrally arranged with the second metal insert and located at the lower end of the wiring slot.

[0017] By adopting the above technical solution, the first metal insert bends upward first when approaching the wiring slot, and then bends vertically to form an L shape to form a plurality of first wiring plugs. The first wiring plugs do not abut against the wiring slot, and the second wiring plugs are also directly integrated with the second metal insert and do not abut against the inner wall of the wiring slot. The first wiring plug and the second wiring plug are distributed in the wiring slot one above and one below, and the power supply can be plugged in without welding the wiring plugs separately, which has higher strength and smoother plugging.
