Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims under 35 U.S.C. § 119(a) priority to Korean Patent Application No. 10-2021-0185948, filed on Dec. 23, 2021, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of the present disclosure relate to a weather strip for a vehicle, which seals between a door and a vehicle body in a vehicle, and more specifically, to a weather strip for a vehicle, which improves the detection performance of an anti-pinch sensor installed therein.

DESCRIPTION OF RELATED ART

A weather strip for sealing when a door is closed is applied to a door of a vehicle, etc.

In addition, a sensor is installed to detect that a passenger's body is pinched between the door and a vehicle body while the door is opened or closed.

For example, in a bus 100 for transporting passengers, a front door is composed of a folding door 120 in which a first member 121 and a second member 122 are folded (see FIG. 1), and an anti-pinch sensor (APS) is installed to detect that the passenger's body is pinched between the door and the vehicle body with which the door is in contact.

In FIG. 2, when the anti-pinch sensor 150 is installed in a weather strip 112 installed on the vehicle body and the passenger's body such as a hand (H) is pinched, a resistance of the anti-pinch sensor 150 is changed by the deformation of the weather strip 112 and the anti-pinch sensor 150 to detect the pinch.

While the folding door 120 is closed, when the pinch is detected by the anti-pinch sensor 150, an actuator 131 configured to operate the first member 121 controls the folding door 120 to be opened. When the actuator 131 operates to open the first member 121 through the rod 132, the first member 121 and the second member 122 are folded to open the folding door 120, thereby preventing the pinch.

Since the anti-pinch sensor 150 is installed in the weather strip 112, an initial installation position should be maintained. However, since the weather strip 112 is formed in a simple shape as shown in FIG. 2 and cannot stably support the anti-pinch sensor 150. Therefore, the anti-pinch sensor 150 installed in the weather strip 112 cannot maintain its position and is separated from the weather strip 112.

Also, in addition to the basic sealing function, the weather strip 112 needs to smoothly deliver external deformation to the inside so that the anti-pinch sensor 150 can easily detect the pinch when the pinch occurs.

However, since the conventional weather strip 112 focuses on the sealing function, the displacement due to the change thereof is not sufficiently delivered to the inside even when the outside of the weather strip 112 changes, and therefore, the anti-pinch sensor 150 does not detect the pinch well.

Meanwhile, the weather strip 140 can be configured to be fitted into a door frame 122a in the second member 122 composed of the door frame 122a and a door panel 122b (see FIG. 3), and the anti-pinch sensor 150 can be installed in the weather strip 140. However, even in this case, there is the aforementioned problem.

The contents described in Description of Related Art are to help the understanding of the background of the present disclosure and may include what is not previously known to those skilled in the art to which the present disclosure pertains.

Hereinafter, a weather strip for a vehicle according to the present disclosure will be described in detail with reference to the accompanying drawings.

A weather strip for a vehicle according to the present disclosure may include a fixing part 41 fixed to a vehicle body or an opening/closing part 20 for a vehicle, a sealing part 42 formed on one side of the fixing part 41 and formed in a hollow cross section therein to seal between the vehicle body and the opening/closing part 20, a sensor installation part 43 positioned in the sealing part 42 to be spaced apart from an inner surface of the sealing part 42 and accommodating the anti-pinch sensor 50 therein, and at least one sensor operation part 45 protruding from the inner surface of the sealing part 42 toward the sensor installation part 43 by a predetermined length in the inner surface of the sealing part 42 to pressurize the sensor installation part 43 when the sealing part 42 is deformed by an external force.

The weather strip 40 according to the present disclosure may be applied to the opening/closing part 20 of the vehicle and applied to seal between the opening/closing part 20 and the vehicle body of the vehicle. In particular, the weather strip 40 may have the anti-pinch sensor 50 configured to detect that a passenger's body is pinched between the opening/closing part 20 and the vehicle body installed therein when the opening/closing part 20 is operated.

For example, the vehicle can be the bus, the opening/closing part 20 may be the folding door 20 opened or closed by operating the first member 21 and the second member 22 in a folding manner to allow passengers to get on or off the bus.

The folding door 20 may be composed of the first member 21 hinge-connected to the vehicle body and the second member 22 hinge-connected to the first member 21. When the actuator 31 operates to open the folding door 20, the rod 32 pulls the first member 21, and the first member 21 and the second member 22 may be folded. When the actuator 31 operates to close the folding door 20, the rod 32 pushes the first member 21, and the first member 21 and the second member 22 may be unfolded and closed.

The anti-pinch sensor 50 may be installed on the end of the second member 22 to detect the pinch when the folding door 20 is completely closed.

FIG. 4 shows a cross-sectional diagram of the weather strip 40 for the vehicle according to the present disclosure. The weather strip 40 may be installed on one side of the folding door 20.

The fixing part 41 may fix the weather strip 40 to the opening/closing part 20 of the vehicle, that is, the folding door 20. The fixing part 41 may fix the weather strip 40 to the second member 22 of the folding door 20. The second member 22 may be composed of a door frame 22a and a door panel 22b provided on the door frame 22a, and the fixing part 41 may be fixed to the door frame 22a, and therefore, the weather strip 40 may be fixed to the door frame 22a.

The sealing part 42 may be formed on one side of the fixing part 41. The sealing part 42 may be formed in a hollow cross section therein, and therefore, when the folding door 20 is in contact with the vehicle body upon closing the folding door 20, the folding door 20 may be easily deformed to seal between the folding door 20 and the vehicle body.

The sensor installation part 43 may be formed in the sealing part 42. The sensor installation part 43 may accommodate the anti-pinch sensor 50 therein, and the anti-pinch sensor 50 may be installed in the sensor installation part 43. The anti-pinch sensor 50 may be formed by a predetermined length in a height direction to detect that the passenger's body is pinched between the second member 22 and the vehicle body when the folding door 20 is closed. The anti-pinch sensor 50 may be inserted into the sensor installation part 43 to detect the pinch.

The sensor support part 44 may allow the sensor installation part 43 to be spaced apart from the inner surface of the sealing part 42 in the sealing part 42. The sensor support part 44 may be formed to connect the inner surface of the weather strip 40 with the outer surface of the sealing part 42 to support the sensor installation part 43. In addition, the sensor support part 44 may be formed to connect the inner surface of the sealing part 42 with the sensor installation part 43 or to connect the fixing part 41 with the sensor installation part 43. In other words, the sensor support part 44 may be formed on a portion of the sensor installation part 43 facing the fixing part 41 and the side surface thereof. The sensor installation part 43 may be supported by a plurality of sensor support parts 44, and therefore, may be positioned on the center of the sealing part 42.

Since the sensor installation part 43 is supported by the sensor support part 44 and formed to be spaced apart from the inner surface of the sealing part 42 in the sealing part 42, the position of the anti-pinch sensor 50 may be maintained. In addition, when the sealing part 42 is deformed, the anti-pinch sensor 50 may operate smoothly.

The sensor operation part 45 may be formed in the inner surface of the sealing part 42 to protrude from the inner surface of the sealing part 42 toward the sensor installation part 43 by a predetermined length. Since the sensor operation part 45 is formed to protrude from the inner surface of the sealing part 42, the sensor installation part 43 may be pressurized when the sealing part 42 is deformed by an external force, thereby improving the detection performance of the anti-pinch sensor 50.

The sensor operation part 45 may have the end protruding from the sealing part 42 at a gap from the sensor installation part 43. If the sealing part 42 is normally deformed (e.g., when the normal folding door is closed), the sensor operation part 45 may not press the sensor installation part 43. But if the sealing part 42 is excessively pressed (e.g., if the passenger's body is pinched between the folding door and the vehicle body), the sensor operation part 45 may press the sensor installation part 43.

The sensor operation part 45 may be formed to face a portion of the sensor installation part 43 where the sensor support part 44 is not installed. In other words, in FIG. 4, since the sensor support part 44 is formed on the side surface and lower side of the sensor installation part 43, the sensor operation part 45 may be formed on the inner surface of the sealing part 42 to face an upper portion of the sensor installation part 43.

Since the sensor operation part 45 is formed at a predetermined angular interval, when the sealing part 42 is excessively pressed regardless of the direction, the sensor installation part 43 may be pressurized so that the anti-pinch sensor 50 is operated.

Meanwhile, the sensor installation part 43 may be formed to be inclined at a predetermined angle. As shown in FIG. 4, the sensor installation part 43 may be formed to be inclined at the predetermined angle with respect to a longitudinal direction (line L-L) of the vehicle. For example, the sensor installation part 43 may be formed to be inclined by 15 degrees with respect to the longitudinal direction of the vehicle. Therefore, as shown in FIG. 6, since the second member 22 performs a closing operation while rotating, it is intended to be pressed to be almost perpendicular to the anti-pinch sensor 50 at any position during the closing operation. Immediately before the folding door 20 is closed, the angle at which the sensor installation part 43 is installed may be formed to be in the same direction as the longitudinal direction of the vehicle, so that the sensor operation part 45 easily presses the sensor installation part 43 if the sealing part 42 is pressed by the pinch.

Meanwhile, among the sensor support parts 44, the sensor support parts 44, formed on the side part of the portion faced the fixing part at the sensor installation part, may be also formed to be inclined. Therefore, immediately before the folding door 20 is closed, the sensor support part 44 connecting the sealing part 42 with the sensor installation part 43 may be formed to be in the same direction as the width direction of the vehicle, so that the sensor support part 44 firmly supports the sensor installation part 43 when the pinch occurs to support the sensor installation part 43 not to be pushed even when the sensor operation part 45 presses the sensor installation part 43, thereby improving the detection performance of the anti-pinch sensor 50.

The inclination of the sensor support part 44 and the inclination of the sensor installation part 43 may be formed at the same angle but are not limited thereto.

Reference numeral 46 (not described) indicates a lip that covers the door panel 22b when the weather strip 40 is fastened to the door frame 22a.

Meanwhile, the structure of the weather strip may also be applied into the weather strip 12 fitted into the panel of the vehicle body instead of being applied to the second member 22 of the folding door 20. In other words, the fixing part 41 of the weather strip may also be fixed to the panel of the vehicle body with which the end of the folding door 20 is in contact.
