- the frame structure 13 can enclose the opening 11 and in particular the button unit 20 on the peripheral side and in particular serve as a potting trough for potting the electronic unit 30 .
- the frame structure 13 can also be used for guiding and/or fastening a cable guide 13B for a bus B.
- the electronics unit 30 can be arranged from an inner side 101 of the carrier housing 10 on the carrier housing 10, in particular at an opening 11 in the carrier housing 10, preferably behind the key cap 21, and/or cast with a casting compound in order to seal the electronics unit 30 fasten and/or seal.
- a sealing element 22 can be arranged on the key cap 21 in order to seal an opening 11 in the carrier housing 10 and in particular to protect the electronics unit 30 from the effects of the weather.
- the sealing element 22 can also be designed to fasten the key cap 21 to the carrier housing 10, preferably to an opening 11 in the carrier housing 10, in particular by a laser welding method, and/or, in particular due to the compressibility of the sealing element 22, to movably support it at least slightly depressible and/or or to store. According to a particular advantage, the sealing element 22 can be designed to enable volume compensation, in particular in an air chamber K, between the key cap 21 and the electronics unit 30 .
- the sealing element 22 can have a fastening area 22b, in particular on a shoulder area that is preferably on the outside and/or collar-shaped when viewed radially, in order to secure the key cap 21 on the carrier housing 10, in particular in a materially bonded manner, preferably by laser welding.
- the fastening area 22b can preferably be designed to be compressible, in order to enable the key cap 21 to be moved relative to the carrier housing 10 .
- FIG. 2 and FIGS. 5 to 7 indicate that the sealing element 22 can have a fold area 22f in order to enable the key cap 21 to be moved relative to the carrier housing 10 .
- the fold area 22f can be designed to enable volume compensation, in particular in an air chamber K, between the key cap 21 and the electronics unit 30 .
- the fold area 22f can have at least one fold, in particular a substantially U-shaped, W-shaped and/or S-shaped fold, and/or be designed in the shape of a bellows.
- the fold area 22f can, for example, be pulled into the chamber when the volume in the air chamber K is reduced and/or compressed in the chamber and/or displaced from the chamber when the volume in the air chamber K is increased.
- the sealing element 22 can have a support region 22s, in particular on a radially innermost support region 22s, in order to fasten the sealing element 22 on the key cap 21, in particular in a materially bonded manner, preferably by a second -Component injection molding process to attach.
- the support area 22s can be designed to enable volume compensation, in particular in an air chamber K, between the key cap 21 and the electronic unit 30.
- the key cap 21 and the sealing element 22 can be designed as a 2-component injection molded part.
- the key cap 21 and the Sealing element 22 or the sealing element 22, preferably at a fastening area 22b, materially bonded, in particular by laser welding, are attached to the carrier housing 10 in order to attach the button unit 20 to the carrier housing 10.
- the key cap 21 can have at least one fastening element 21b, in particular hook-shaped or claw-shaped, for the activation element 24, in particular for a carrier plate 23 for the activation element 24.
- the at least one fastening element 21b can be used to fasten the activation element 24 to the key cap 21, for example by heat caulking or ultrasonic welding of the at least one fastening element 21b. In this way, the activation element 24 can be fixed at a distance from the inside 211 of the key cap 21 .
- a method according to the invention for producing a modular component 100 for a movable part 201 of a vehicle 200 has the following steps:
- a carrier housing 10 for fastening the module component 100 to the movable part 201 of the vehicle 200, and in particular for the movable support of a button unit 20 and preferably for fastening an electronic unit 30 (cf. Figures 3 to 7),
- Support e.g. movable support, of the key cap 21, in particular from the outside, means the area of accessibility for the user when the modular component 100 is mounted on the vehicle 200, on the carrier housing 10 for receiving an activation action, in particular a touch and/or an exertion of force , a user (see Figure 3),
- an electronic unit 30 for providing lighting functions and/or sensor functions when moving part 201 of vehicle 200 is actuated with a sensor unit 31, 32 for detecting presence and/or detecting an activation action on activation element 24 and at least one lighting unit 33 for transilluminating key cap 21 (cf . the figure 4)
- Fastening an electronics unit 30, in particular from the inside means the area that is inaccessible to the user when the module component is mounted on the vehicle, on the carrier housing 10 (cf. FIG. 4).
- the activation element 24 can be attached to the key cap 21 before or after the key cap 21 is supported on the carrier housing 10, for example by heat staking or ultrasonic welding.
