Description

Technical Field

[0001] This disclosure relates to an auxiliary handle device configured for use when entering or leaving a vehicle. More specifically, the present invention relates to an auxiliary handle device configured for use when entering and leaving a vehicle, wherein the handle device is configured to selectively lower from the lateral side of the vehicle roof toward the open door when the door is opened, so as to be grasped by a passenger, thereby assisting elderly or disabled passengers in entering or leaving the vehicle. Background Technology

[0002] Typically, multiple auxiliary handles are located at the upper part of both sides of the vehicle's interior. These handles are designed for passengers to grip. The auxiliary handles are located inside the vehicle, below the headliner, and are fixedly attached to the vehicle's body panels.

[0003] When auxiliary handles are installed on vehicles such as vans, they can be used to help passengers enter the vehicle. With the advent of vehicles with structures that omit the B-pillar, the role of auxiliary handles as a means of assisting passengers, such as the elderly or disabled, to enter the vehicle is being strengthened.

[0004] Specifically, although the elderly are considered the main consumers due to the aging of the world's population, the demand for vehicles for the elderly has not yet been met.

[0005] Therefore, vehicles equipped with amenities suitable for the elderly or disabled are being researched. In particular, vehicles for disabled persons are equipped with various devices such as lifts, swivel seats, wheelchair transport devices, and foot-driven direction indicators.

[0006] This device differs from those designed to compensate for overall physical deficiencies (reductions). In other words, comprehensive research on deficiencies in character recognition and color discrimination, as well as the ease of entering and exiting vehicles, remains insufficient.

[0007] Therefore, research has been actively conducted on vehicles equipped with cluster lighting devices for constantly lit lights, or vehicles in which handles that passengers grip when entering or leaving the vehicle are attached to the seat backs.

[0008] As a result of such research, in conventional vehicles, auxiliary handles are installed on the side surfaces of the vehicle seats so that older or disabled passengers can effectively grip them when entering and exiting the vehicle.

[0009] However, because these assistive handles for vehicles are mounted on the side surface of the seat at a low level, it is difficult for elderly or disabled passengers to grip the handles when entering or leaving the vehicle, and it is also difficult for passengers to support their weight when standing while gripping the handles.

[0010] The information disclosed in this background section is only intended to enhance the understanding of the background of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art in China. Summary of the Invention

[0011] This disclosure aims to address the aforementioned problems associated with the prior art. The object of this disclosure is to provide an auxiliary handle device configured for use when entering or leaving a vehicle, the auxiliary handle device being constructed such that when a signal indicating that the door is open is transmitted to a controller, a guide frame is slidably moved, and thus a pair of guide pins move along a moving guide, thereby selectively rotating the handle unit downwards from the side of the vehicle roof toward the open door, thereby producing the effect of allowing the handle unit to be grasped by a passenger and thus assisting elderly or disabled passengers in entering or leaving the vehicle.

[0019] In another preferred embodiment, the first position may be such that the first guide pin is located at the boundary between the first path and the second path, and the second guide pin is located at the second end of the second moving guide, such that the handle unit protrudes downward from the mounting plate toward the outside of the vehicle.

[0020] In another preferred embodiment, the second position may be such that the first guide pin and the second guide pin are located at the second end of the first moving guide and the second moving guide, respectively, such that the handle unit protrudes downward from the mounting plate toward the interior of the vehicle.

[0021] In another preferred embodiment, the auxiliary handle device may further include multiple sensors disposed at the sliding movement path of the guide frame unit so as to detect the position of the handle unit based on the positions of the first guide pin and the second guide pin when the first guide pin and the second guide pin contact the guide frame unit.

[0022] In yet another preferred embodiment, the plurality of sensors may be three sensors configured to detect the positions of the handle unit corresponding to the rest position, the first position, and the second position.

[0043] In the following, various embodiments of the present disclosure will be described in detail, examples of which are illustrated in the accompanying drawings and described below. While the present disclosure will be described in conjunction with exemplary embodiments, it should be understood that this description is not intended to limit the present disclosure to the exemplary embodiments. Rather, the present disclosure is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit and scope of the present disclosure as defined by the appended claims.

[0044] Preferred embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0045] Referring to the accompanying drawings, the above-mentioned objects, as well as other objects, features, and advantages, will become clear from the following preferred embodiments.

[0046] However, this disclosure is not limited to these embodiments and will be implemented in different forms. The recommended embodiments are merely intended to provide a thorough and complete understanding of the disclosure and to fully inform those skilled in the art of the technical conception of this disclosure. This disclosure is limited only by the class of the claims.

[0047] Furthermore, in the following description of the embodiments disclosed herein, such detailed descriptions are omitted if it is determined that a detailed description of a known function or construction related to this disclosure would obscure the subject matter of this disclosure.

[0048] Figure 1 This is a view showing the location of an auxiliary handle device configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure. Figure 2 This is a view illustrating the structure of an auxiliary handle device configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure.

[0049] Figure 3 This is a view illustrating the operation of a guide frame of an auxiliary handle device configured for use when entering and leaving a vehicle, according to an embodiment of the present disclosure. Figure 4 This is a view illustrating the operation of a handle unit of an auxiliary handle device configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure. Figure 5 This is a view showing a first guide pin and a second guide pin of an auxiliary handle device configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure.

[0050] like Figure 1 As shown, the auxiliary handle device 10, configured for use when entering and leaving the vehicle according to an embodiment of the present disclosure, can be provided at each of the two sides of the roof 1, particularly between the two top ventilation grilles 2 mounted on the roof of the second-row passenger space.

[0051] The auxiliary handle device 10 is configured to selectively protrude toward the second-row passenger space to assist passengers in entering and exiting the vehicle.

[0052] Therefore, the auxiliary handle device 10 includes a cover unit 100, a guide frame unit 200, and a handle unit 300, such as Figure 2 and Figure 4 As shown.

[0053] The cover unit 100 includes a pair of cover units 110, 120, which are disposed on both sides of the mounting plate 10a of the two roof ventilation grilles 2 connected to the second row space of the vehicle so as to face each other.

[0054] Specifically, each cover unit 100 may consist of a first cover unit 110 and a second cover unit 120 connected to each other, with the first cover unit 110 disposed inside the cover unit 100 and the second cover unit 120 disposed outside the cover unit 100.

[0055] The first cover unit 110 includes a first movable guide 112, which extends a predetermined length to define a movement path (see [link]). Figure 6B ).

[0056] The second cover unit 120 includes a second movement guide 122, which has the same dimensions as the first cover unit 110 and is connected to the outside of the first cover unit 110. The second movement guide 122 includes a movement guide facing the first movement guide 112 and disposed adjacent to the movement path, such as... Figure 5 As shown.

[0057] Here, the second moving guide 122 can be configured to have a predetermined slope and extend in the downward direction of the second cover unit 120.

[0058] The guide frame unit 200 includes a pair of guide frame units disposed between a pair of cover units 100 facing each other and surrounding the upper surface of the first cover unit 110. The pair of guide frame units are connected to each other via a connecting rod 210 and are slidably movable along a guide rail 12 disposed on a mounting plate 10a.

[0059] Specifically, when the motor M rotates, the rotational force of the motor M is transmitted to the helical gear 12a via its worm gear. As the helical gear 12a rotates, the lead screw 220, which is threaded into the guide rail 12, moves longitudinally and slidably, causing the guide frame unit 200 to slide when connected to the first cover unit 110.

[0060] Therefore, when the guide frame unit 200 slides in the manner described above, the handle unit 300 connected to the cover unit 100 selectively protrudes downward from the mounting plate 10a, as... Figure 4 As shown.

[0061] The handle unit 300 is rotatably connected to the guide frame unit 200, which is disposed between the first cover unit 110 and the second cover unit 120, thereby surrounding the first cover unit 110.

[0062] like Figure 5 As shown, the handle unit 300 includes: a first guide pin 302 disposed in the first moving guide 112; and a second guide pin 304 spaced apart from the first guide pin 302 and disposed in the second moving guide 122.

[0063] When the guide frame unit 200 is slidably moved, the first guide pin 302 and the second guide pin 304 move along the first moving guide 112 and the second moving guide 122 while maintaining a constant distance between them. As a result, the handle unit 300 protrudes downward from the mounting plate 10a, as... Figure 4 As shown.

[0064] Because the handle unit 300 protrudes downward from the mounting plate 10a in the manner described above, passengers can easily grasp the handle unit 300 when the door is open. Therefore, it can effectively assist elderly or disabled passengers in getting into the second-row passenger space of the vehicle.

[0065] Figure 6A and Figure 6B This is a view showing the installation state of an auxiliary handle device configured for use when entering or leaving a vehicle according to an embodiment of the present disclosure. Figure 7A and Figure 7B This is a view showing a first position of an auxiliary handle device configured for use when entering or leaving a vehicle according to an embodiment of the present disclosure. Figure 8A and 8B This is a view showing a second position of an auxiliary handle device configured for use when entering or leaving a vehicle according to an embodiment of the present disclosure.

[0066] An auxiliary handle device configured for use when entering or leaving a vehicle according to an embodiment of the present disclosure is constructed such that: when the guide frame unit 200 is slidably moved, the handle unit 300 rotates sequentially from a rest position to a first position and a second position.

[0067] stationary position

[0068] The second movement guide 122 is configured to protrude downward from the second cover unit 120 and extend downward, and the first movement guide 112 includes: a first path 112a, disposed parallel to the second movement guide 122 of the second cover unit 120; and a second path 112b, which bends upward at one end of the first path 112a to be spaced apart from the second movement guide 122 in the vertical direction.

[0069] Specifically, the second path 112b may be bent upward relative to the first path 112a at a predetermined angle, such that one end of the second path 112b is spaced apart from one end of the second moving guide 122 by a length corresponding to the distance between the first guide pin 302 and the second guide pin 304.

[0070] like Figure 6A and 6BAs shown, the stationary position can be set as follows: the first guide pin 302 and the second guide pin 304 are respectively located at the first end of the first moving guide 112 and the first end of the second moving guide 122, and the handle unit 300 is retracted into the mounting plate 10a.

[0071] The rest position can be set as the initial position of the first guide pin 302 and the second guide pin 304. Because the handle unit 300 is exposed to the outside on the smallest surface area of ​​the handle unit 300 in the rest position, the rest position can be the position when the door is closed.

[0072] First position

[0073] like Figure 7A and Figure 7B As shown, the first position can be set as follows: the first guide pin 302 is located at the boundary between the first path 112a and the second path 112b, that is, at the curved area of ​​the first moving guide 112, and the second guide pin 304 is located at the second end of the second moving guide 122.

[0074] As described above, because the first guide pin 302 moves while maintaining a constant distance relative to the second guide pin 304, when the guide frame unit 200 moves slidably together with the handle unit 300, the second guide pin 304, positioned in front of the first guide pin 302, is engaged and held there by the second end of the second moving guide 122.

[0075] When the second guide pin 304 is engaged and held there by the second end of the second moving guide 122, the first guide pin 302 is located at the boundary between the first path 112a and the second path 112b.

[0076] Therefore, when the first guide pin 302 and the second guide pin 304 move along the first moving guide 112 and the second moving guide 122 respectively and thus reach the first position, the handle unit 300 protrudes downward from the mounting plate 10a toward the outside of the vehicle.

[0077] In other words, the first position can be defined as follows: the first guide pin 302 and the second guide pin 304 of the handle unit 300 are slidably moved along the first moving guide 112 and the second moving guide 122 by sliding the guide frame unit 200, such that the handle unit 300 protrudes toward the outside of the vehicle to serve as an auxiliary handle for passengers.

[0078] Because the handle unit 300 protrudes from the inside of the vehicle to the outside to minimize interference from the inside of the vehicle, the handle unit 300 can be used as an auxiliary handle for passengers and can prevent passengers' heads from colliding with the handle unit 300.

[0079] Second position

[0080] When the guide frame 200 is further slidably moved from a first position in which the second guide pin 304 is located at the second end of the second movable guide 122, the first guide pin 302 moves to the second end of the first movable guide 112, causing the handle unit 300 to rotate toward the interior of the vehicle to protrude downward from the mounting plate 10a.

[0081] like Figure 8A and Figure 8B As shown, the second position can be set as follows: the first guide pin 302 and the second guide pin 304 are respectively locked and held there by the second ends of the first moving guide 112 and the second moving guide 122.

[0082] Therefore, because the handle unit 300 protrudes almost vertically downward from the mounting plate 10a toward the vehicle interior and the first guide pin 302 and the second guide pin 304 are respectively engaged and held there by the second ends of the first moving guide 112 and the second moving guide 122, the passenger's load can be stably supported.

[0083] Therefore, since the handle unit 300 can be selectively moved from a stationary position to a first position or from a first position to a second position so as to protrude downward from the mounting plate 10a when the door is opened, passengers can easily enter the second row of the vehicle while gripping the handle unit 300.

[0084] Figure 9 This is a view showing a sensor unit of an auxiliary handle device configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure.

[0085] like Figure 9 As shown, the auxiliary handle device 10, configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure, may further include a sensor unit 400.

[0086] The sensor unit 400 includes a plurality of sensors mounted on the sliding movement path of the guide frame unit 200 and capable of detecting the position of the handle unit 300 and the positions of the first guide pin 302 and the second guide pin 304 by selective contact with the slidably movable guide frame unit 200.

[0087] Specifically, the sensor unit 400 may include three sensors configured to detect a position of the handle unit 300 corresponding to one of the rest position, the first position, and the second position.

[0088] The sensor unit 400 is connected to an additional controller (not shown) to transmit the detected values ​​to the controller. Therefore, the controller is able to effectively determine which position the handle unit 300 is in among the rest position, the first position, and the second position.

[0089] Figure 10 This is a view showing the gripping member of a handle unit configured for use when entering and leaving a vehicle according to an embodiment of the present disclosure. Figure 11 This illustrates an auxiliary handle device configured for use when entering and exiting a vehicle according to an embodiment of the present disclosure, along... Figure 10 The cross-sectional view taken from line AA in the diagram.

[0090] like Figure 10 As shown, an auxiliary handle device 10 configured for use when entering or leaving a vehicle according to an embodiment of the present disclosure includes a handle unit 300. The handle unit 300 includes a connecting member 310 and a gripping member 320.

[0091] The connecting member 310 includes a pair of connecting members, which respectively include a first guide pin 302 and a second guide pin 304, and are mounted on the cover unit 100 which is connected to the two front and rear ends of the mounting plate 10a.

[0092] Specifically, the connecting member 310 is installed between the first cover unit 110 and the second cover unit 120 at the two front and rear ends of the mounting plate 10a.

[0093] The gripping member 320 connects a pair of connecting members 310 to each other. When the handle unit 300 is in the first or second position, the gripping member 320 protrudes downward from the mounting plate 10a so that it can be gripped by passengers entering the vehicle or sitting in the seat.

[0094] like Figure 11 As shown, the gripping member 320 may include an LED light source 322 and a transmission lens 324.

[0095] The LED light source 322 is mounted in mounting area A of the gripping member 320 and connected to the PCB of the mounting plate 10a to be used as a lamp. When power is supplied to the LED light source 322, the LED light source 322 emits selective light.

[0096] Alternatively, the LED light source 322 can be replaced with lighting lamps of different colors or ultraviolet germicidal lamps.

[0097] In other words, the LED light source 322 can be replaced with white and yellow lights, so that the light source is used as a welcome light when the car door is opened, and as an ambient light when the car door is closed.

[0098] In addition, the LED light source 322 can be replaced with an ultraviolet germicidal lamp to disinfect the gripping component 320, or to disinfect clothing when the gripping component 320 is used as a clothes hanger.

[0099] A transmission lens 324 is mounted on the front surface of the gripping member 320 so that light emitted from the LED light source 322 is transmitted through the transmission lens 324.

[0100] Figure 12 This is a view illustrating the sequence of operations of an auxiliary handle device configured for use when entering or leaving a vehicle according to an embodiment of the present disclosure.

[0101] Reference Figure 12 The operation of the auxiliary handle device configured for use when entering or leaving the vehicle according to embodiments of the present disclosure is described sequentially when a passenger enters the vehicle.

[0102] When the door is switched to the open state in S100, the controller (not shown) performs control to turn on the LED light source 322 to be used as a welcome light, and at the same time, the motor M is activated in S200 to rotate the helical gear 12a.

[0103] In S300, the guide frame unit 200 is slidably moved by the rotation of the helical gear 12a. Therefore, the first guide pin 302 and the second guide pin 304 move along the first moving guide 112 and the second moving guide 122 so that in S300 and S400 the handle unit 300 is moved sequentially from the rest position to the first position and then to the second position.

[0104] Therefore, because the handle unit 300 is moved to the second position, passengers can easily enter the second row of the vehicle while gripping the handle unit 300.

[0105] At this time, when an additional weight sensor (not shown) determines that a passenger is seated in the second row of seats, S500 determines whether the passenger is using the handle unit 300.

[0106] When it is determined that the handle unit is in use, the handle unit 300 is moved from the second position to the first position in S510 so that the passenger can grasp the handle unit 300, and then the door is switched to the closed state in S600.

[0107] When the door transitions from this state to the open state again, because the handle unit 300 remains in the first position, the passenger exits the vehicle while gripping the handle unit 300. Subsequently, when the door closes, the handle unit 300 moves from the first position to the stationary position.

[0108] On the other hand, when it is determined in S500 that the handle unit is not in use, the handle unit 300 moves from the second position to the first position and then moves to the rest position in S520 to retract into the mounting plate 10a, so that the handle unit 300 is not exposed to the outside. Subsequently, in S600, the door is switched to the closed state.

[0109] When the door switches from the open position to the open position again, because the handle unit 300 remains in the stationary position, it moves back to the first position so that the passenger can grip the handle unit 300 and exit the vehicle while gripping it. Subsequently, when the door closes again, the handle unit 300 moves from the first position to the stationary position.

[0110] As is evident from the description above, when a signal indicating that the door is open is transmitted to the controller, the guide frame can slide and thus a pair of guide pins move along the moving guide, so that the handle unit selectively rotates downward from the side of the vehicle roof toward the open door, thereby producing the effect of allowing the handle unit to be grasped by passengers and thus assisting elderly or disabled passengers in entering or leaving the vehicle.

[0111] Furthermore, since the movable handle unit is selectively moved to one of the stationary position, the first position, and the second position by sliding the guide frame, it has the effect of helping passengers enter or leave the vehicle and enabling passengers to sit in the second row of seats while gripping the handle unit.

[0112] Furthermore, since the light source is incorporated into the gripping member constituting the handle unit and the light emitted from the light source is transmitted to the outside through the lens of the gripping member, the handle unit can be selectively used as a welcome lighting, ambient lighting, or ultraviolet sterilization device by the user's operation.

[0113] This disclosure has been described in detail with reference to preferred embodiments thereof. However, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of this disclosure, the scope of which is defined by the appended claims and their equivalents.
