Description

Technology Field

[0001] The present invention relates to a wire assembly for a pinch detection sensor of a vehicle that connects a pinch detection sensor installed inside the weatherstrip of the vehicle to a controller. Background Technology

[0003] A pinch detection sensor is installed on the vehicle door to detect when a passenger's body is caught between the door and the vehicle body during boarding or alighting.

[0004] Among vehicles, in the case of buses, especially urban buses where passengers frequently board and alight, an anti-pinch sensor (APS) is provided to detect when a passenger's body is caught in the door when the door is closed. When the anti-pinch sensor detects a passenger being caught, the door is opened again, thereby preventing safety accidents caused by a body such as a hand (H) being caught between the door and the body such as the frame (111).

[0005] The front door (120) of the bus (100) may be provided as a folding door. Typically, the folding door (120) has a first member (121) and a second member (122) connected to each other in a foldable manner, and the first member (121) is connected to an actuator (131) through a rod (132). When the folding door (120) is in an unfolded state, if the actuator (131) operates to pull the rod (132), the first member (121) and the second member (122) operate to fold, thereby opening.

[0006] A weather strip (140) for airtightness is applied to the other end (the end not connected to the first member) of the second member (122) and to the vehicle body in contact therewith. In particular, the pinch detection sensor (150) is installed in the height direction of the vehicle inside the weather strip (140) installed on the vehicle body in contact with the other end of the second member (122). The pinch detection sensor (150) is connected to a controller (133) that controls the operation of the actuator (131), so that when the pinch detection sensor (150) detects a pinch, the controller (133) operates the actuator (131) to open the folding door (120).

[0007] Meanwhile, as the pinch detection sensor (150) is installed on the vehicle body side, there is a problem in that the width of the opening area is reduced by the thickness of the pinch detection sensor (150) when the folding door (120) is opened. When the folding door (120) is opened, the width of the opening area is limited by regulations, and the larger the opening area, the more advantageous it is for passengers to board. However, there is a problem in that the width of the opening area is reduced only by the thickness of the pinch detection sensor (150).

[0008] In order to resolve this, when the pinch detection sensor (150) is to be installed on the folding door (120), as the folding door (120) is repeatedly folded, it is difficult to securely mount the wire connecting the pinch detection sensor (150) and the controller (133), and there is a problem of reduced durability.

Specific details for implementing the invention

[0036] A wire assembly for a pinch detection sensor of a vehicle according to the present invention will be described in detail below with reference to the attached drawings.

[0038] The wire assembly for a pinch detection sensor of a vehicle according to the present invention can be applied to a folding door (20) comprising a first member (21) hinge-connected to the body of a vehicle such as a bus, and a second member (22) foldably installed on the first member (21).

[0039] The first member (21) is connected to an actuator (31) and a rod (32) that are operated by the control of a controller (33). When the controller (33) controls the opening of the actuator (31), the actuator (31) pulls the first member (21), causing the first member (21) and the second member (22) to fold, thereby opening the folding door (20). Additionally, when the controller (33) controls the closing of the actuator (31), the actuator (31) pushes the first member (21), causing the first member (21) and the second member (22) to unfold, thereby closing the folding door (20).

[0040] A pinch detection sensor (50) for detecting passenger entrapment is installed on one side of the second member (22), that is, on the part where the second member (22) contacts the vehicle body when the folding door (20) is closed. The pinch detection sensor (50) is installed inside a weather strip installed on the part where the second member (22) contacts the vehicle body.

[0041] When a pinch occurs between the second member (22) and the vehicle body, the pinch detection sensor (50) detects this and transmits a pinch signal to the controller (33). When the controller (33) receives the pinch signal, it controls the actuator (31) to open again so that the folding door (20) is opened.

[0042] When the pinch detection sensor (50) is installed on the second member (22), the opening area of ​​the folding door (20) can be increased because no installation space is required compared to when the pinch detection sensor (50) is installed on the vehicle body. However, durability is reduced because the wire connecting the pinch detection sensor (50) and the controller (33) is installed inside the first member (21) and the second member (22), which repeatedly fold and unfold.

[0043] To resolve this, by applying the wire assembly according to the present invention, durability can be ensured even if the pinch detection sensor (50) is installed on the second member (22).

[0044] A wire assembly for a pinch detection sensor of a vehicle according to the present invention comprises a lead wire unit (61) connected to the pinch detection sensor (50), a center wire unit (62) having one end connected to the lead wire unit (61) and installed at a folding portion of the door (20), and a connecting wire unit (63) having one end connected to the other end of the center wire unit (62) and the other end connected to the controller (33), and extending from the inside of the door (20) to the outside by penetrating the door (20).

[0045] The lead wire unit (61) is installed inside the second member (22), the center wire unit (62) is installed across the first member (21) and the second member (22), and the connecting wire unit (63) is partially installed inside the first member (21) and the remainder passes through the first member (21) and the vehicle's step panel (12) to connect to the controller (33). The lead wire unit (61), the center wire unit (62), and the connecting wire unit (63) are installed along the inner perimeter of the door (20) and electrically connect the pinch detection sensor (50) and the controller (33).

[0046] The lead wire unit (61) includes a lead wire (61a) that electrically connects the pinch detection sensor (50) and the center wire unit (62), and a connector (61b) provided at the end of the lead wire (61a) and connected to the center wire unit (62).

[0047] The lead wire (61a) is composed of a wire and a sheath, and transmits the pinch signal of the pinch detection sensor (50).

[0048] The lead wire unit (61) is installed along the circumference of the second member (22) and electrically connects the pinch detection sensor (50) and the center wire unit (62).

[0049] By being fixed to the second member (22) with a cable tie (64) at a location adjacent to the end of the lead wire unit (61), that is, at a location adjacent to the connector (61b), the position can be maintained even if the folding door (20) is repeatedly folded and unfolded.

[0050] The center wire unit (62) includes a center wire (62a) connecting the lead wire unit (61) and the connecting wire unit (63), a coil portion (62b) in which the center wire (62a) is wound in the form of a coil in the middle of the center wire (62a) and extends in the longitudinal direction of the center wire unit (62), and a wire cover (62c) wound on the outside of the center wire (62a).

[0051] The center wire unit (62) is installed over the upper circumference of the first member (21) and the upper circumference of the second member (22), and is exposed to the outside at the portion where the first member (21) and the second member (22) are folded.

[0052] Since the center wire unit (62) also needs to transmit an electrical signal, it basically has a wire structure equipped with a conductor and a sheath. The center wire (62a) electrically connects the lead wire unit (61) and the connecting wire unit (63) to transmit the pinch signal of the pinch detection sensor (50) to the controller (33).

[0053] The coil portion (62b) is formed in a portion of the center wire unit (62). The coil portion (62b) is formed by forming the center wire (62a) into a coil shape. Since the coil portion (62b) is extendable in the longitudinal direction of the center wire unit (62), when the first member (21) and the second member (22) are repeatedly folded and unfolded, the coil portion (62b) absorbs the change in the length of the center wire unit (62). In this way, by the coil portion (62b) absorbing the change in the length of the center wire unit (62), the durability of the wire assembly is improved.

[0054] The wire cover (62c) is made of a metal cable and is formed to wrap around the outer side of the center wire (62a). This wire cover (62c) covers most of the section of the center wire unit (62), excluding the part where the coil portion (62b) and the center wire (62a) are connected to the connector (62e). By doing so, the center wire (62a) is prevented from coming into direct contact with the frame of the first member (21) and the second member (22), or with the center weather strip (21a) (22a), thereby allowing the center wire (62a) to move smoothly when the folding door (20) is folded or unfolded.

[0055] Meanwhile, in the part where the door (20) passes through the foldable portion of the center wire unit (62), it is supported through a cable guide (62d).

[0056] The above cable guide (62d) is manufactured from a synthetic resin injection molded product or the like and is installed at the portion where the first door (20) and the second door (20) are connected. The above cable guide (62d) is formed in a cylindrical shape and is installed inside the center weather strip (21a) (22a) installed at the portion where the folding door (20) is folded, that is, at the portion where the first door (20) and the second door (20) are connected. Since the above cable guide (62d) is formed in a cylindrical shape, the center wire (62a) and the wire cover (62c) pass through the above cable guide (62d), and the above cable guide (62d) supports the outer side of the wire cover (62c). A hook (62da) is formed at the rear end of the cable guide (62d), so that it is securely fastened in a hook manner to the door frame of the first door (20) and the second door (20), or to the door side such as the center weather strip (21a) (22a).

[0057] At each end of the center wire unit (62), a connector (62e) is formed to be connected to the lead wire unit (61) and the connecting wire unit (63). The connector (62e) is mechanically coupled to the connector (61b) of the lead wire unit (61) and the connector (63b) of the connecting wire unit (63), thereby firmly securing the connection between the lead wire unit (61), the center wire unit (62), and the connecting wire unit (63).

[0058] In addition, the center wire unit (62) is secured to the door (20) with a cable tie (64) at a location adjacent to the connector (62e). This ensures that the folding door (20) maintains its position even when operated repeatedly.

[0059] The above connecting wire unit (63) includes a connecting wire (63a) that connects the center wire unit (62) and the controller (33), and a connector (63b) provided at the end of the connecting wire (63a) and connected to the center wire unit (62).

[0060] The connecting wire (63a), like the lead wire (61a) and the center wire (62a), basically has a wire structure for transmitting electrical signals.

[0061] The above connecting wire unit (63) can also be secured to the door (20) with a cable tie (64) at a location adjacent to the connector (63b).

[0062] A portion of the connecting wire unit (63) is installed around the first member (21), and the remainder is drawn out to the outside by penetrating the first member (21), then inserted into the interior of the vehicle through the vehicle's step panel (12) and connected to the controller (33). Grommets (21b) (12a) are installed at the portion where the connecting wire unit (63) penetrates the first member (21) and the step panel (12) to ensure airtightness and support the connecting wire unit (63).

[0063] FIGS. 12a to 12d illustrate the state in which the center wire unit (62) is exposed for each state during the opening and closing operation of the folding door (20). As the folding door (20) opens from the closed state (see FIG. 12a), the amount of exposure of the center wire unit (62) increases, and reaches a maximum when the folding door (20) is fully open. Conversely, when the folding door (20) is closed, the amount of exposure of the center wire unit (62) gradually decreases.

[0064] Meanwhile, even if the opening and closing of the folding door (20) is repeated, causing a part of the center wire unit (62) to be exposed and the folding process to be repeated, the wire cover (62c) reduces friction with the center wire (62a) while absorbing the length due to expansion and contraction by the coil part (62b), allowing for smooth operation.
