Description

[0001] Power window switch and operating method [0002]

The present invention relates to vehicle technology, and more particularly, to a power window switch and a driving method thereof.

Due to the breakthrough of electronic control technology, various devices which were operated by mechanical methods in vehicles have been driven by electrical methods for reasons such as convenience of the driver and safety of operation, and automobile systems are gradually advanced and advanced It is going.

Generally, a window is provided on each door of a vehicle, and a user (rider) can raise or lower the window appropriately or completely with the help of a driving device. Nowadays, because of its convenience, Most of the power windows are used to raise or lower the window by a simple switch operation rather than manual operation.

However, as PowerWindow develops, the following need arises.

First, reduction of the power window switch is required to secure space in the vehicle and to secure design freedom. Specifically, there are different contact operation mechanisms for each company, which makes it difficult to standardize dimensions for miniaturization of switches.

Second, there is a demand for improvement of sensibility quality with miniaturization of power window switch. Specifically, the power window switch can be driven by two types of specifications: high current direct drive (eg, non-IMS, spring elastic) and small current indirect drive (eg IMS, rubber elastic) There is a difficulty in standardizing emotional quality. In particular, even if the same vehicle model is equipped with a power window switch of different specifications, inconvenience may be caused.

Third, slimmer design of the door armrest on which the power window is mounted is required from the design point of view. Fourth, when the power window is mounted on the door, the assembly space is narrow and there are inconveniences for the workers.

The prior art will be described with reference to Figs. 1 (a) to 1 (e). 1 (a) to 1 (d) show a direct current motor direct drive switch. The prior art may include a structure in which a module switch is disposed on an upper side of a PCB and an internal contact is turned on / off by pushing up and down a module switch in a shape of a window knob. In addition, the conventional art performs a window knob seesaw operation, and the switch restoring force can be realized by a spring-loaded spring window knob fixed in the box (including a metal ball) and a box-shaped arch structure.

According to Fig. 1 (b), when the switch is pressed by a user operation, the movable contact and the fixed contact are connected by the curling structure and can be electrically driven. Here, a module switch is disposed on the upper surface of the PCB. In Fig. 1 (c), when the switch is depressed by a user operation, the switch can be smoothly and smoothly driven by the pedestrian and the spring-coupled housing. Figure 1 (d) shows a module switch of the prior art. The module switch is placed on the top of the PCB and can be combined with the module switch terminal through a DIP (Dual Line Package) structure. The detailed description will be described later, and will not be described here. Fig. 1 (e) shows a small current motor indirect drive switch. The low current motor indirect drive switch can provide elasticity through the rubber keypad and pusher, while the high current motor direct drive switch provides the resilience using the pedestal, spring and ball.

As a result, miniaturization, standardization, and improved quality of sensibility are required.

2 (a) and 2 (b) are views for explaining a power window switch according to an embodiment. Fig. 2 (a) shows a prior art power window switch, and Fig. 2 (b) shows a power window switch according to an embodiment.

Specifically, the module switch may be disposed on the bottom surface of the PCB in the present invention if it is disposed on the top surface of the PCB in the prior art. If the module switch terminal type is a DIP (Dual Line Package) in the prior art, SMT (Surface Mount Technology) may be adopted in the present invention. As a result, PCB hole drilling becomes unnecessary. Here, the SMT method refers to a technique of automatically mounting components (semiconductor, diode, chip) on a PCB (Printed Circuit Board) with one or more equipment and joining them to the PCB with a bond or a cream solder for electrical connection of the components .

If the module switch fixing method is a PCB upper mounting method in the prior art, the fixing clip structure can be employed in the present invention. Accordingly, even if the module switch is disposed on the bottom surface of the PCB, it can be firmly fixed. The position of the module switch terminal may be disposed at the top of the module box in the present invention if it is the bottom of the module box in the prior art. The module switch operating force / click rate may be a rubber keypad or a plunger in the present invention if a spring, a ball, a pedestrian mountain, or the like is used in the prior art. Accordingly, the operation feeling is improved and the improvement of the emotional quality can be expected.

Accordingly, the weight of the power window switch can be reduced and the height of the switch can be reduced (for example, the height can be reduced by 21% by 11.1 mm, and the weight is reduced by 10% by 17 g)

On the other hand, the power window switch can be configured to enable communication.

3 (a) and 3 (b) are views for explaining the arrangement of the module switches according to the embodiment.

3 (b) is a diagram showing the arrangement of the module switches according to the embodiment. According to Fig. 3 (b), the module switches 20-1 and 20-2 are disposed on the lower surface of the PCB line 21.

Module switches 20-1 and 20-2 are mounted on the bottom surface of the PCB so that the overall height 33 of the power window switch is less than the height 31 of the prior art. Thus, the power window switch can be configured space-efficient. In addition, even if the vehicle is the same, the switch can be unified regardless of the option specification. To this end, the large current contact arrangement can be configured to be compatible with the small current contact arrangement. The detailed description will be omitted in FIG. 8 and FIG. 9 and will not be described here.

4 (a) and 4 (b) are views for explaining a module switch terminal according to the embodiment.

Fig. 4 (a) shows the module switch terminals 30-1, 30-2, 31-1 and 31-2 in the prior art. In the prior art, the module switch terminals 30-1, 30-2, 31-1, and 31-2 may be disposed at the bottom of the module box. Thus, holes are required in the PCB. Here, the module switch terminals 30-1, 30-2, 31-1, and 31-1 employ a DIP (Dual Line Package) method.

4 (b) shows an embodiment. The module switch terminals 33-1, 33-3 and 33-5 may be disposed at the top of the module box and may be fixed to the PCB by a SMT (Surface Mount Technology) method . This eliminates the need to drill holes in the PCB.
