Description

Technical Field

[0001] This disclosure relates to a handle device for a vehicle. Background Technology

[0002] As a handle device having a handle body that can be pulled out from an initial position when operating the door, the device described in Patent Document 1 is known.

[0003] Conventional pop-up handle devices, including Patent Document 1, typically include: a handle body rotatably connected to one end of a working lever, the working lever being fixed to a handle base and driven by an electric actuator; and a locking release lever connected to the end of the handle body opposite to the connection end of the working lever. Furthermore, when the electric actuator is activated, the handle body moves from an initial position located on the same side as the door panel to an operating position where it is raised from the door panel. When the handle body is operated in the operating position, the door latch device can be released.

[0004] In such a handle device, a motor, which acts as an electric actuator, drives a cam component to rotate via gears. The rotation of the cam component drives the working lever to move the handle body to a position where it is lifted off the door panel.

[0005] Furthermore, the aforementioned handle devices are sometimes fixed to the left and right doors of the vehicle, respectively. In the left and right handle devices, the left and right directions are opposite to each other and the rotation is reversed (i.e., the rotation direction is opposite). Therefore, different types of components (especially gears and cam components) must be prepared to match the left and right handle devices.

[0006] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 2018-168689 Summary of the Invention

[0007] The problem that the invention aims to solve This disclosure provides a vehicle handle device that enables component universality when fixed to either the left or right door of a vehicle.

[0008] Solution for solving the problem According to this disclosure, the handlebar device of the vehicle includes: Handle base, fixed to the vehicle; The handle body is connected to the handle base and can be displaced from its initial position by a drive device; Gears, driven to rotate by the drive device; and A cam member has a mating portion that engages with a mating portion formed at the shaft end of the gear, and is rotated by the gear via the mating portion, wherein... The handle body has a passive portion that abuts against the cam member, and the handle body is configured to be displaced via the passive portion and the cam member. In the cam member, the mating portions are respectively formed at both ends in the rotation axis direction of the cam member, and the shapes of the mating portions are different at one end and the other end in the rotation axis direction.

[0009] Alternatively, the shape of the mating part may be such that the engagement angle between the gear and the cam member is different on one end and the other end.

[0010] Alternatively, one of the fitting portion and the fitted portion may be formed in a generally cylindrical shape. The fitting portion and the other square portion of the fitted portion are approximately cylindrical in shape. The fitting portion is provided with one of a radially protruding protrusion and a groove that engages with the protrusion. The other of the protrusion and the groove is provided in the fitting portion. The fitted portion has: a concave-convex region having the protrusion or the groove; and an arcuate region not having the protrusion or the groove, wherein the concave-convex region and the arcuate region are circumferentially misaligned on one end side and the other end side.

[0011] In addition, it can also possess: An initial position sensing sensor is used to sense that the handle body is positioned at the initial position; A pop-out position sensing sensor is used to sense the pop-out position of the handle body, which is positioned after being pulled out from the initial position; and A circuit board for mounting the initial position sensing sensor and the pop-up position sensing sensor.

[0012] Furthermore, the gear may also have a sensing portion on the circumference of its rotational surface. In the circuit board, the initial position sensing sensor and the pop-up position sensing sensor may also be disposed on the surface opposite to the sensed part. The handlebar assembly of this vehicle can also be configured to detect that the handlebar body is positioned in the initial position based on the proximity of the sensed part detected by the initial position sensing sensor, and to detect that the handlebar body is positioned in the pop-out position based on the proximity of the sensed part detected by the pop-out position sensing sensor. The circuit board can also be formed so that the front and back sides are symmetrical.

[0025] The specific embodiments involved in this disclosure will be described below with reference to the figures.

[0026] For ease of explanation, the following is as follows: Figure 1 As shown, "front," "back," "left," "right," "up," and "down" are defined. The "front-back direction," "left-right direction," and "up-down direction" are mutually orthogonal.

[0027] Here, the aforementioned directions may also correspond, for example, to the directions in which the handle device 1 is mounted on the vehicle. In this case, Figure 1 The handlebar device 1 shown is a handlebar device mounted on the left side of the vehicle. However, the left-side handlebar device and the right-side handlebar device have the same configuration except that the left-right orientation is opposite to each other and the rotation operation is reversed (i.e., the rotation direction is opposite).

[0028] For ease of explanation, the following will be... Figures 1 to 8B The illustrated scheme is configured as a handlebar device 1 fixed to the left side of the vehicle, which... Figure 9 The illustrated scheme is designed as a handlebar device 1 fixed to the right side of the vehicle, but in reality... Figures 1 to 8B The solution shown can also be a handlebar device 1 fixed to the right side of the vehicle. Figure 9 The solution shown can also be configured as a handle device 1 fixed to the left side of the vehicle.

[0029] like Figure 1 As shown, the handle device 1 includes a handle base 2, a handle body 3, and a rotary drive mechanism 16 for moving the handle body 3 between an initial position and a pop-out position, and is fixed to the vehicle door at the handle base 2.

[0030] The handle body 3 is connected to the handle base 2 via a first link 11 and a second link 12. A gripper portion 3a is formed at the center in the front-rear direction, serving as a gripper for door operation. When the handle base 2 is fixed to the door, the surface 3b of the handle body 3 is approximately flush with the door surface 5 (door panel) (see reference). Figure 2 ).

[0031] Furthermore, the handle body 3 can be accommodated in the initial position inside the door by the grab handle 3a (see reference). Figure 2 The grab handle 3a protrudes from the door panel and allows the hand to be gripped to operate the pop-out position of the handle body 3 (see reference). Figure 3 ) and the latching operation position that lifts one end of the handle body 3 (the rear end in this example) from the pop-out position (see Figure 4 Move between ).

[0032] In the first link 11, the driven part 11a is pressed by a rotary drive mechanism (specifically, cam member 13) that drives the rotation, and is rotated about the connecting shaft (A1) with the handle base 2. To maintain the pressed state between the driven part 11a and the cam member 13, a counterclockwise torque is applied to the first link 11 by a torsion spring 14. It should be noted that the detailed configuration of the rotary drive mechanism 16 including the cam member 13 will be described later.

[0033] Furthermore, the first link 11 is rotatably connected to one end of the handle body 3 about the connecting shaft (B1) with respect to the end connected to the handle base 2.

[0034] One end of the second link 12 is rotatably connected to the handle base 2 around the connecting shaft (A2). An elongated hole 12a is formed at the opposite end of the second link 12, through which the connecting shaft (B2) fixed to the other end of the handle body 3 can be freely inserted and rotated freely.

[0035] Therefore, the components of the handle device 1 are configured as follows: the handle base 2 serves as a fixed link; the first link 11 and the second link 12, which are connected to the fixed link via a revolute joint, and the slider (elongated hole 12a), which is connected to the second link 12 via a sliding joint, are connected to the first link 11 and the slider via revolute joints at both ends; and the handle body 3, which is connected to the first link 11 and the slider via revolute joints at both ends, constitutes a five-section linkage mechanism (see reference). Figures 2-4 ).

[0036] Furthermore, the end of the sliding stroke of the slider sliding on the second link 12 is predetermined to be the end position of the elongated hole 12a. In addition to the torque applied to the first link 11, a counterclockwise torque is applied to the second link 12 via the torsion spring 15, thereby keeping the slider at the end of its stroke on the side of the connecting shaft (A2) between the second link 12 and the handle base 2.

[0037] Furthermore, the connecting rods of the fixed link and the handle body 3 are approximately the same length, and the distance between the slider at the end of the stroke and the connecting shaft (A2) of the second link 12 and the fixed link (i.e., Figure 2 The distance between A2 and B2 is formed to be approximately the same as the length of the first link 11. Therefore, when the first link 11 is used as a drive link for electric rotation, it actually functions as a four-section parallel link.

[0038] Therefore, when the surface 3b of the handle body 3 is approximately flush with the door panel (door surface 5) in the initial state (refer to...) Figure 2 When the first link 11 is rotated clockwise, the handle body 3 moves parallel to it and moves to the pop-out position (refer to...). Figure 3 ).

[0039] From this position, manually rotate the handle body 3 clockwise to the latching position (see reference). Figure 4 When the first link 11 is restricted from rotating clockwise around the connecting shaft (A1) with the handle base 2, the second link 12 rotates around the connecting shaft (B1) for the rotation of the handle body 3, and the connecting shaft B2 translates within the elongated hole 12a. Thus, it essentially functions as a slider-crank mechanism with the handle body 3, the second link 12, and the slider as movable links. Figure 3 The state shown indicates that the device can be further rotated by a specified angle.

[0040] On the other hand, the handle base 2 is provided with a connecting shaft (B1) to the handle base 2 via the second connecting rod 12. Figure 3 Towards Figure 4 The latching mechanism (not shown) operates by rotating the handle body 3. As the handle body 3 rotates to the working position, the latching mechanism releases the door latch device fixed to the door via a suitable transmission unit such as a cable device. Alternatively, the latching mechanism can be configured as a switch, and the transmission unit transmits a signal from the switch to the door latch device.

[0041] The detailed configuration of the rotary drive mechanism 16 will be described below. Figures 5-7 as well as Figure 9 As shown, the rotary drive mechanism 16 consists of a motor 17, a worm gear 18, a double gear 19, a main gear 20 (equivalent to "gear" in this disclosure), a shaft 21 of the main gear 20, a circuit board 22, an initial position sensing sensor 23, a pop-out position sensing sensor 24, and a cam member 13.

[0042] As the motor 17 moves, the rotary drive mechanism 16 causes the worm gear 18, double gear 19, main gear 20, and cam component 13 to move, thereby moving the handle body 3 between the initial position and the pop-out position.

[0043] In the rotary drive mechanism 16, an initial position sensing sensor 23 and a pop-out position sensing sensor 24 are mounted on the circuit board 22 along the rotational trajectory of the rib 20a of the main gear 20. It should be noted that the initial position sensing sensor 23 and the pop-out position sensing sensor are configured as touch switches that sense contact with the rib 20a, but any sensor capable of sensing the proximity of the rib 20a is acceptable. For example, a magnet could be used instead of the rib 20a to function as a Hall sensor sensing the proximity of the magnet, or other non-contact sensors could be used. When the initial position sensing sensor 23 or the pop-out position sensing sensor 24 senses the rib 20a, the handle body 3 is positioned in either the initial or pop-out position based on the rotation angle of the cam member 13 across the main gear 20. The detection result is used to control the operation of the motor 17 (i.e., the rotational drive of the cam member 13). The following is a detailed description of each part.

[0044] like Figures 5-7 As shown, the motor 17 has a motor shaft 17a, which receives an electrical supply to rotate. The worm gear 18 is a threaded gear, which is mounted on the top end of the motor shaft 17a.

[0045] The double gear 19 is a set of gears consisting of a first gear 19a and a second gear 19b with different numbers of teeth, both having a coaxial rotating shaft and being integrally arranged in a double-layered configuration. In the double gear 19, the first gear 19a is configured to mesh with a worm 18, and the second gear 19b is configured to mesh with a main gear 20. The first gear 19a has more teeth than the second gear 19b. The double gear 19 rotates as the worm 18 rotates.

[0046] The main gear 20 meshes with the second gear 19b of the double gear 19. An arc-shaped rib 20a, serving as a sensing part, is provided on the upper surface of the main gear 20, corresponding to its circumferential shape. A shaft portion 21 is integrally formed on the lower surface of the main gear 20, its lower end becoming the engagement part 13a with the cam member 13. Figures 1 to 8B The scheme shown is the upper region 13aa, in Figure 9 The shown design includes a fitting portion 21a that fits into the lower region 13ab). Therefore, the fitting portion 21a is formed in a shape corresponding to the fitting portion 13a of the cam member 13. The fitting portion 21a is provided with a plurality of protrusions (five in this example) that protrude radially and extend in the vertical direction, and the protrusions fit into the groove of the fitting portion 13a, which will be described later.

[0047] The circuit board 22 is, for example, a printed circuit board that mounts circuitry for controlling the operation of the motor 17. Here, the surface of the circuit board 22 on the side of the main gear 20 is designated as surface A, and the opposite surface is designated as surface B. On surface A of the circuit board, an initial position sensing sensor 23 and a pop-out position sensing sensor 24 are mounted on the rotational trajectory of the rib 20a of the main gear 20. That is, the contact between the rib 20a and the initial position sensing sensor 23 or the pop-out position sensing sensor 24 is sensed by the circuitry mounted on the circuit board 22.

[0048] The circuit board 22 is formed symmetrically, allowing the upper and lower sides to be reversed for use (see special reference). Figure 6A , Figure 6B as well as Figure 9 That is, surface B can be set as the side of the main gear 20, and the initial position sensing sensor 23 and the pop-out position sensing sensor 24 can be mounted on surface B. Therefore, components can be installed by simply reversing the front and back of the circuit board according to the left-right pattern, thus achieving the universality of the circuit board.

[0049] The cam component 13 is a component that rotates in conjunction with the main gear 20 to drive the first connecting rod 11. For example... Figure 8A , Figure 8B As shown, the cam member 13 has a mating portion 13a that extends in the vertical direction and is mated to the mating portion 21a of the main gear 20.

[0050] The fitting portion 13a is a generally cylindrical through hole, having: a concave-convex region 13b with multiple (five in this example) grooves for fitting the protrusions of the fitting portion 21a; and an arcuate region 13c without multiple grooves.

[0051] The outer periphery of the cam member 13 is symmetrically shaped. On the other hand, as described above, the mating portion 13a is arranged in the upper region 13aa and lower region 13ab with a concave-convex region 13b and an arcuate region 13c offset circumferentially (in this example, offset by 60 degrees around the axis of rotation). That is, the mating portion 13a in the cam member 13 is formed in different styles. Therefore, in the handle device 1, the cam member 13 can be used even when it is fixed to either the left or right door of the vehicle without preparing cam members of different styles.

[0052] It should be noted that the direction of use of the cam member 13 is clarified by forming a mark on at least one of the upper and lower end faces of the cam member 13. Furthermore, in the mating portion 13a, the circumferential misalignment of the concave-convex region 13b and the arcuate region 13c of the upper region 13aa and the lower region 13ab is appropriately determined by taking into account the mounting positions of the initial position sensing sensor 23 and the pop-out position sensing sensor 24 on the circuit board 22, the positional relationship between these sensing sensors and the rib 20a of the main gear 20, etc.

[0053] As explained above, according to this embodiment, the shape of the fitting portion 13a of the cam member 13 is different in the upper region 13aa and the lower region 13ab (that is, the shape of the fitting portion is formed in different styles). Therefore, it is not necessary to prepare cam members with different styles to match the left and right handle devices as in conventional handle devices. The universality of the components including the cam member 13 can be achieved when the handle device 1 is fixed to either the left or right door of the vehicle.

[0054] Furthermore, according to this embodiment, the mating portion 13a is formed with different mating angles with the main gear 20 in the upper region 13aa and the lower region 13ab. Therefore, by adjusting the mating angle, the shape of the mating portion 13a can be formed in different patterns. That is, according to this embodiment, with a simple structure, the components including the cam member 13 can be universalized even when fixed to either the left or right door of the vehicle.

[0055] Furthermore, according to this embodiment, the upper region 13aa and the lower region 13ab of the mating portion 13a are arranged with a circumferentially offset concave-convex region 13b and an arcuate region 13c, thereby allowing the shape of the mating portion 13a to be formed in different patterns by adjusting the amount of offset (i.e., the size of the offset angle centered on the rotation axis). In other words, according to this embodiment, with a simple structure, the components including the cam member 13 can be universalized even when the handle device 1 is fixed to either the left or right door of the vehicle.

[0056] Furthermore, according to this embodiment, by also including an initial position sensing sensor 23, an ejection position sensing sensor 24, and a circuit board 22 for mounting the initial position sensing sensor 23 and the ejection position sensing sensor 24, it becomes easier to control the movement between the initial position and the ejection position of the handle body 3.

[0057] Furthermore, according to this embodiment, the circuit board 22 is formed with front and back symmetry, thereby enabling the circuit board 22 to be universally applicable even when the handle device 1 is fixed to either the left or right door of the vehicle.

[0058] It should be noted that this disclosure is not limited to the above-described embodiments, and appropriate modifications and improvements can be made. Furthermore, the material, shape, size, quantity, and arrangement of the constituent elements in the above embodiments are arbitrary and not limited, as long as they achieve the desired effect as disclosed in this disclosure.

[0059] For example, in the above embodiment, the handlebar device 1 is configured as a slider crank structure using a connecting rod, but it can also be configured as a rotary handlebar device in which the handlebar body 3 is directly supported by the handlebar base 2. Furthermore, in the above embodiment, it is configured as a pop-out handle where the handlebar body 3 pops out, but it can also be configured as a retractable handle where the handlebar body is housed inside the door. Additionally, in the above embodiment, the rotation axis of the handlebar body 3 extends along the vertical direction of the vehicle, but the rotation axis of the handlebar body 3 can also extend along the horizontal direction of the vehicle.

[0060] The handlebar device (1) of the vehicle disclosed herein includes: Handle base (2), fixed to the vehicle; The handle body (3) is connected to the handle base (2) and can be displaced from the initial position by a drive device (motor 17); The gear (main gear 20) is driven to rotate by the drive unit (motor 17); and The cam member (13) has a fitted portion (13a) that engages with a fitting portion (21a) formed at the shaft end of the gear (main gear 20), and is rotated by the gear (main gear 20) via the fitted portion (13a). The handle body (3) has a passive portion (11a) that abuts against the cam member (13), and the handle body (3) is configured to be able to move via the passive portion (11a) through the cam member (13). In the cam member (13), the fitted portion (13a) is formed at both ends of the cam member (13) in the direction of rotation axis, and the shape of the fitted portion (13a) is different at one end and the other end in the direction of rotation axis.

[0061] According to this configuration, the shape of the mating portion of the cam member differs between one end and the other end in the direction of rotation. Typically, conventional handle devices are sometimes separately fixed to the left and right doors of a vehicle, requiring cam members of different designs to be prepared to match the left and right handle devices. However, according to this configuration, since the shape of the mating portion differs between one end and the other end in the direction of rotation—that is, the shape of the mating portion is formed in different ways—the component can be universally used regardless of whether it is fixed to either the left or right door of the vehicle.

[0062] Alternatively, the shape of the mating part (13a) may be such that the engagement angle between the gear (main gear 20) and the cam member (13) is different on one end side and the other end side.

[0063] According to this configuration, the mating part is formed with different mating angles with the gear on one end and the other end, thereby allowing the mating part to be shaped in different ways by adjusting the mating angle. That is, according to this configuration, the component can be universally used even when fixed to either the left or right door of a vehicle, thanks to its simple construction.

[0064] Alternatively, one of the fitting portion (21a) and the fitted portion (13a) may be formed in a generally cylindrical shape. The other square shape in the fitting portion (21a) and the fitted portion (13a) becomes approximately cylindrical. The fitting portion (21a) is provided with one of a radially protruding protrusion and a groove that engages with the protrusion. The other of the protrusion and the groove is provided in the fitting portion. The fitted portion has: a concave-convex region (13b) having the protrusion or the groove; and an arcuate region (13c) without the protrusion or the groove, the concave-convex region (13b) and the arcuate region (13c) being circumferentially misaligned on one end side and the other end side.

[0065] According to this configuration, the concave and convex regions and the arcuate regions are circumferentially offset on one end and the other end of the mating part. Thus, by adjusting the amount of offset (i.e., the size of the offset angle centered on the rotation axis), the shape of the mating part can be formed in different ways. In other words, according to this configuration, with a simple structure, the component can be universally used even when fixed to either the left or right door of a vehicle.

[0066] In addition, it can also possess: An initial position sensing sensor (23) is used to sense the handle body (3) being positioned at the initial position; A pop-out position sensing sensor (24) is used to sense the pop-out position of the handle body (3) as it is pulled out from the initial position; and Circuit board (22) for mounting the initial position sensing sensor (23) and the pop-up position sensing sensor (24).

[0067] According to this configuration, by also including an initial position sensing sensor, an ejection position sensing sensor, and a circuit board for mounting the initial position sensing sensor and the ejection position sensing sensor, it becomes easy to control the movement between the initial position and the ejection position of the handle body.

[0068] Furthermore, the gear (main gear 20) may also have a sensing portion (rib 20a) on the circumference of the rotating surface of the gear (main gear 20). In the circuit board (22), the initial position sensing sensor (23) and the pop-up position sensing sensor (24) may also be disposed on the surface opposite to the sensed part (rib 20a). The handlebar device (1) of the vehicle can also be configured to detect that the handlebar body (3) is positioned in the initial position based on the proximity of the sensed part (rib 20a) sensed by the initial position sensing sensor (23), and to detect that the handlebar body (3) is positioned in the pop-out position based on the proximity of the sensed part (rib 20a) sensed by the pop-out position sensing sensor (24). The circuit board (22) can also be formed with the surface and back side symmetrical.

[0069] According to this configuration, by forming circuit boards symmetrically on the front and back sides, components can be installed simply by reversing the front and back sides of the circuit board when it is fixed to either the left or right door of the vehicle, thus achieving the universality of the circuit board.

[0070] The various embodiments have been described above, but this disclosure is not limited to such examples. Those skilled in the art will obviously conceive of various modifications or alterations within the scope of the claims, and it should be understood that these modifications or alterations also fall within the technical scope of this disclosure. Furthermore, the constituent elements of the above embodiments can be combined arbitrarily without departing from the spirit of the disclosure.

[0071] It should be noted that this application is based on Japanese patent application (Japanese Patent Application No. 2023-202813) filed on November 30, 2023, the contents of which are incorporated herein by reference.
