Description

Power window switch and its driving method {Power Window Switch and Operating Method Thereof}

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

With the rapid development of electronic control technology, various devices that used to be operated by mechanical methods in vehicles are driven by electric methods for reasons such as driver convenience and driving safety. is going

In general, a window is installed on each door part of a vehicle, and a user (occupant) raises or lowers the window moderately or completely with the help of a driving device. Power windows that raise and lower the window with a simple switch operation rather than the manual type that raises and lowers the window while turning are mostly installed.

However, as the power window is developed, the following needs arise.

First, a reduction in the power window switch is required to secure space in the vehicle and secure design freedom. Specifically, since the contact operation mechanism for each company is different, it is difficult to standardize the dimensions for miniaturization of the switch.

Second, along with the miniaturization of the power window switch, there is a demand for improvement of emotional quality. Specifically, the power window switch can be driven with two specifications: a high current direct drive method (eg, Non IMS, spring elasticity) and a small current indirect drive method (eg, IMS, rubber elasticity). There are difficulties in standardizing emotional quality. In particular, even in the same vehicle model, power window switches of different specifications are mounted, which causes inconvenience.

Third, in terms of design, it is required to slim the door armrest on which the power window is mounted. Fourth, when the power window is mounted on the door, the assembly space is narrow, which causes inconvenience to workers.

The prior art will be described with reference to FIGS. 1(a) to 1(e). 1(a) to 1(d) show a high-current motor direct drive switch. The prior art may include a structure in which the module switch is placed on the top of the PCB, and the internal contact is On/Off by moving the pusher of the module switch up and down in the shape of a window knob. In addition, the prior art performs the window knob seesaw operation, and the switch restoring force can be implemented with the spring (including metal ball) of the window knob fixed in the box and the structure of the box.

According to FIG. 1( b ), when the switch is pressed by the user's operation, the movable contact and the fixed contact are connected by a curling structure to be electrically driven. Here, the module switch is disposed on the upper surface of the PCB. When the switch is pressed by the user's manipulation in Fig. 1(c), the switch can be driven somewhat naturally and smoothly by the housing in which the jeoldosan and the spring are combined. Figure 1 (d) shows a module switch of the prior art. The module switch is disposed on the upper surface of the PCB and may be coupled to the module switch terminal through a dual line package (DIP) structure. A detailed description will be given later and will be omitted here. 1(e) shows a small current motor indirect drive switch. A small current motor indirect drive switch can provide elasticity through a rubber keypad or a pusher, compared to a large current motor direct drive switch using a jigsaw mountain, a spring and a ball to provide elasticity.

Accordingly, there is a need for a power window switch with improved miniaturization, standardization, and emotional quality.

2(a) and 2(b) are diagrams for explaining a power window switch according to an embodiment. Figure 2 (a) shows a power window switch of the prior art, Figure 2 (b) shows a power window switch according to the embodiment.

Specifically, if the module switch is disposed on the upper surface of the PCB in the prior art, it may be disposed on the lower surface of the PCB in the present invention. If the module switch terminal type is a dual line package (DIP) in the prior art, a surface mount technology (SMT) method may be employed in the present invention. Accordingly, the PCB hole drilling becomes unnecessary. Here, the SMT method refers to a technology that automatically mounts components (semiconductors, diodes, chips) on a PCB (Printed Circuit Board) with one or multiple equipment and joins them to the PCB with Bond or Cream Solder for electrical connection of components. .

If the module switch fixing method is a PCB top mounting method in the prior art, a fixing clip structure may be employed in the present invention. Accordingly, even if the module switch is disposed on the lower surface of the PCB, it can be firmly fixed. If the module switch terminal position is at the bottom of the module box in the prior art, it may be disposed at the top of the module box in the present invention. As for the module switch operating force/click rate, if a spring, a ball, a jeoldosan, etc. are used in the prior art, a rubber keypad, a plunger may be used in the present invention. Accordingly, a feeling of operation is improved, and an improvement in 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 (eg, the height can be reduced by 21% when the height is 11.1mm, the weight can be reduced by 10% when the weight is reduced by 17g)

Meanwhile, the power window switch may be configured to enable communication.

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

Figure 3 (a) is a view for explaining the arrangement of the module switch of the prior art. According to FIG. 3( a ), in the prior art, module switches 10 - 1 and 10 - 2 are disposed on the upper surface of the PCB line 21 .

Figure 3 (b) is a view showing the arrangement of the module switch according to the embodiment. According to FIG. 3B , 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 lower surface of the PCB, so that the overall height 33 of the power window switch is smaller than the height 31 of the prior art. Accordingly, the power window switch may be configured in a space-efficient manner. In addition, even in the same vehicle, the switch may be unified regardless of the option specification. For this purpose, the contact arrangement for high current can be configured to be compatible with the contact arrangement for small current. A detailed description will be given in FIGS. 8 and 9 and will be omitted herein.

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

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

Figure 4 (b) according to the embodiment module switch terminals (33-1, 33-3, 33-5) may be disposed on the top of the module box, may be fixed to the PCB by SMT (Surface Mount Technology) method . Accordingly, there is no need to drill a hole in the PCB.
