The present invention relates to a vehicle actuator such as a fuel lid lock device.
The fuel lid lock device holds the fuel lid that opens and closes the fuel supply opening of the vehicle in a locked state and switches between a locked state and an unlocked state. Specifically, the fuel lid is held in a locked state by the output portion of the lock member disposed so as to be able to advance and retreat being engaged with the engagement hole of the fuel lid. Further, when the output portion of the lock member is disengaged from the engagement hole, the locked state is switched to the unlocked state.
Since the output part of the lock member is located in the fuel supply opening in the locked state, rain water or car wash water may adhere. If the lock member is locked or unlocked with water droplets attached to the output portion, the attached water droplets may enter the fuel lid lock device. If water droplets that have entered the apparatus freeze, the internal components may stick and cause malfunction.
Patent Document 1 discloses a fuel lid actuator that ensures water tightness. The actuator includes a lock member, a cylindrical hole-like support portion that holds the lock member so as to be movable back and forth, and an O-ring-shaped seal member provided on the outer periphery of the lock member. The seal member is disposed so as to be in sliding contact with the inner peripheral surface of the support portion, and prevents water from entering from between the support portion and the lock member.
However, it is not possible to completely prevent water droplets from entering the apparatus simply by disposing the seal member on the outer periphery of the lock member. In addition, when a water droplet permeates between the lock member and the support portion and the water droplet freezes, the lock member is fixed inside the support portion, which may cause a malfunction.
JP 2002-240579 A
An object of the present invention is to provide a vehicle actuator that can reliably prevent water droplets from entering.
The present invention provides a casing having an opening, a cylindrical guide member disposed in the opening of the casing, and a protruding position that is held by the guide member and protrudes outward from the opening and the guide member. And an output member that is movable at least partially inside the casing, the output member being disposed between the output portion of the output member , A grease storage portion for storing grease is provided on the outer periphery or the inner periphery of the guide member , and the grease storage portion is an annular groove formed of a semicircular recess extending in the circumferential direction. the moving direction at an interval that has provided a plurality to provide an actuator for a vehicle. Here, the retracted position where the output unit has retracted into the casing includes both the state in which the tip of the output unit protrudes from the opening and the state in which the tip of the output unit is drawn into the opening. Moreover, both the state in which the front end of the output unit protrudes from the guide member and the state in which the front end of the output unit is drawn into the guide member are included.
In this vehicle actuator, the grease stored in the grease storage portion spreads over the sliding portion between the output portion of the output member and the guide member, and the gap between the output portion and the guide member is filled with grease. . Therefore, it is possible to prevent water droplets from entering through the gap between the output portion and the guide member. Therefore, malfunction due to freezing of water droplets can be prevented. Moreover, even if the viscosity of the grease decreases due to heat or the like, the grease storage portion provided in the output portion or the guide member can prevent the grease from flowing out, so that a waterproof effect can be exhibited over a long period of time.
In addition, by providing a plurality of grease storage portions composed of semicircular recesses extending in the circumferential direction along the movement direction of the output member, the grease is almost entirely in the gap between the output portion of the output member and the guide member. Since it becomes easy to spread, it is possible to prevent water droplets from entering the gap.
The grease storage part is provided in the output part of the output member. In this way, the configuration of the guide member and the output member can be simplified, so that the manufacturing cost can be reduced.
The grease storage portion is provided at a position that does not protrude from the guide member of the output portion when the output member is in the protruding position. Here, the output member of the vehicle actuator is in the protruding position that locks the lid for most of the normal use time of the vehicle, and the output member is positioned in the retracted position for a limited time such as when refueling. is there. Therefore, the possibility that the water droplets that have entered between the output member and the guide member in the retracted position are frozen is low, and the possibility that an operation failure occurs in the retracted position is low. Considering this, by providing the grease storage portion at a position that does not protrude from the guide member of the output member when the output member is in the protruding position, the guide member that may be loaded during the lid lock It is possible to prevent malfunction due to freezing of water droplets while maintaining the strength of the protruding portion.
The output member includes a pressure contact portion that is continuous to the rear side of the output portion and has a larger diameter than the output portion, and the guide member includes a first tubular portion that holds the output portion, and the first tubular shape. The first cylindrical portion having a diameter larger than the portion and a second cylindrical portion that continuously holds the pressure contact portion via a stepped portion. In this way, the grease moves along the inner peripheral surface of the first cylindrical portion when the output member moves backward, but adheres to the output portion side when the guide is released by the stepped portion. Or it sticks to the edge of the step and stays on the step. And since the grease adhering to the output part side and the grease collected on the step part are inserted into the first cylindrical part again by the movement of the output member in the protruding direction, it is possible to prevent the grease from flowing out and to be waterproofed over a long period of time. Can be demonstrated.
It is preferable to provide a ring-shaped seal member on the outer periphery of the output member behind the grease storage portion. Specifically, the seal member is provided on the outer periphery of the pressure contact portion of the output member. If it does in this way, a double waterproof effect can be exhibited with grease and a sealing member. Moreover, since the grease can prevent the grease from flowing out to the rear end side of the output member, the waterproof effect can be maintained for a long time.
In the vehicle actuator of the present invention, since the grease stored in the grease storage portion is filled in the gap between the output portion of the output member and the guide member, water drops are generated from the gap between the output portion and the guide member. Intrusion can be prevented. Therefore, malfunction due to freezing of water droplets can be prevented.

The pressure contact portion 27g is disposed in an insertion portion 12j formed on the left side of the lock member accommodating portion 12h in FIG. A guide member 30 made of metal and having both ends opened is fixed to the inner peripheral portion of the insertion portion 12j in order to hold the output portion 27a and the pressure contact portion 27g movably. A seal structure is provided between the guide member 30 and the lock member 27 to prevent water droplets attached to the output portion 27 a from entering the casing 11.
(Details of seal structure)
As shown in FIGS. 2 and 4A, the insertion portion 12j of the casing 11 is generally cylindrical, and a pressure contact portion 27g including the output portion 27a is movably disposed via the guide member 30. At the outer end of the insertion part 12j, an opening part 12k is formed to project the output part 27a outward. A pad 14 (for example, made of rubber sponge) is mounted on the outer end surface of the insertion portion 12j around the opening portion 12k for buffering between the casing 11 and the vehicle body side. That is, the portion of the casing 11 through which the output portion 27 a side of the lock member 27 passes is not substantially divided into two parts, but is constituted by an insertion portion 12 j that is a part of the lower case 12.
As shown in FIG. 4A, the guide member 30 includes a flange-shaped portion 30a disposed in the opening 12k of the insertion portion 12j. In the guide member 30, the first cylindrical portion 30b on the left side from the flange-shaped portion 30a protrudes outward from the opening 12k, and the second cylindrical portion 30e on the right side from the flange-shaped portion 30a is embedded in the lower case 12 by insert molding. ing.
As shown in FIGS. 5A and 5B, the first cylindrical portion 30b holds the output portion 27a of the lock member 27 so as to be movable. The first cylindrical portion 30b has a non-circular outer shape, and includes a screw groove 30c for fixing the guide member 30 to an inner panel in a fuel supply opening (not shown) on the outer periphery thereof. In the fuel lid lock device 10, the first cylindrical portion 30b of the guide member 30 is disposed so as to penetrate through an attachment hole formed in the inner panel in the fuel supply opening from the inside of the vehicle toward the outside of the vehicle, and penetrates the attachment hole. A nut (not shown) is screwed into the distal end portion of the first tubular portion 30b, and the inner panel is sandwiched between the flange-like portion 30a of the guide member 30 and the nut, thereby being fixed around the mounting hole of the inner panel. In this attached state, the first cylindrical portion 30b of the guide member 30 protrudes from the attachment hole of the inner panel into the fuel supply opening, and the tip thereof is disposed at a position corresponding to the engagement hole of the fuel lid. As shown in FIGS. 4A and 5C, the first tubular portion 30b includes a first guide through hole 30d that penetrates the output portion 27a from the second tubular portion 30e side to the front end side.
As shown in FIGS. 4A and 5C, the second cylindrical portion 30e holds the pressure contact portion 27g of the lock member 27 so as to be movable. The second cylindrical portion 30e includes a second guide through hole 30f in which the press contact portion 27g is disposed. The second guide through hole 30f is continuous with the first guide through hole 30d. Thereby, the inside of the casing 11 (the lock member accommodating portion 12h) and the outside of the casing 11 communicate with each other via the first and second guide through holes 30d and 30f. The inner diameter of the second guide through hole 30f is larger than the inner diameter of the first guide through hole 30d. In the flange-shaped portion 30a, which is a boundary portion between the first and second guide through holes 30d and 30f, a tapered shape having a diameter that gradually increases from the first guide through hole 30d side to the second guide through hole 30f side. The step portion 30g is formed.
As shown in FIGS. 4A and 6, the output portion 27a of the lock member 27 is disposed in the first cylindrical portion 30b of the guide member, and is between the protruding position shown in FIG. 4A and the retracted position shown in FIG. 4B. It is movable. As shown in FIG. 4A, at the protruding position, the front end side of the output portion 27 a protrudes outward from the opening 12 k of the casing 11 and the first tubular portion 30 b of the guide member 30. Thereby, the output part 27a is engaged with the engagement hole of the fuel lid, and the fuel lid is held in a locked state. As shown in FIG. 4B, in the retracted position, the output portion 27a is retracted (drawn) into the casing 11, and the tip of the output portion 27a is stored in the first cylindrical portion 30b. As a result, the output portion 27a is detached from the engagement hole, and the fuel lid is switched from the locked state to the unlocked state. However, the output portion 27a in the retracted position protrudes outward from the opening 12k of the casing 11.
The outer peripheral portion of the output portion 27a and the inner wall of the first cylindrical portion 30b that defines the first guide through hole 30d are positioned with a set clearance (gap) for holding the output portion 27a movably. . In order to spread the grease in a fine gap that is a sliding portion of the output portion 27a, a grease storage portion 27h is formed on the outer periphery of the output portion 27a. The grease storage portion 27h is an annular groove formed of a semicircular recess extending in the circumferential direction, and stores (fills) grease that is a semi-solid lubricant. A plurality of grease storage portions 27h are provided along the axis of the output portion 27a, which is the moving direction of the output portion 27a. As shown in FIG. 4A, when the lock member 27 is in the protruding position, the grease storage portion 27h is located in the first cylindrical portion 30b and is provided at a position that does not protrude outward from the guide member 30. As shown in FIG. 4B, when the lock member 27 is in the retracted position, the grease storage portion 27h is located in the second cylindrical portion 30e.
As shown in FIGS. 4A and 6, the pressure contact portion 27g is continuous so as to be positioned on the same axis line on the rear side of the output portion 27a. The outer diameter of the pressure contact portion 27g is larger than that of the output portion 27a, and a clearance that is set to hold the pressure contact portion 27g movably is formed from the inner wall of the second cylindrical portion 30e that defines the second guide through hole 30f. Located. An annular groove is formed in the pressure contact portion 27g, and a ring-shaped seal member 28 having a substantially annular shape and a lip is attached to the annular groove. The seal member 28 is made of an elastic material such as rubber. As shown in FIG. 4A, when the lock member 27 is in the protruding position, the pressure contact portion 27g is located on the stepped portion 30g side of the second cylindrical portion 30e. As shown in FIG. 4B, when the lock member 27 is in the retracted position, the pressure contact portion 27g is located at the rear end in the second cylindrical portion 30e. A rod portion 27i connected to the intermediate portion 27d is provided at the rear end of the pressure contact portion 27g. The rod portion 27i has a + -shaped cross-sectional shape. The diameter of the imaginary circle connecting the four ends of the rod portion 27i is smaller than the outer diameter of the pressure contact portion 27g.
Operation | movement of the fuel lid lock apparatus 10 which concerns on this embodiment is demonstrated.
Referring to FIG. 3, when the motor 20 is actuated by power feeding through the terminal 13, the worm gear 23 rotates together with the output shaft 21 (see arrows B1 and B2). The rotation of the worm gear 23 is transmitted to the gear member 25 by meshing between the worm gear 23 and the inclined gear portion 25a of the gear member 25, and converted into rotation around the support portion 12g of the gear member 25 (see arrows C1 and C2). . The rotation of the gear member 25 around the support portion 12g is transmitted to the lock member 27 by meshing between the spur gear portion 25b of the gear member 25 and the rack gear 27e of the lock member 27, and converted into a linear movement of the lock member 27 (arrow). A1, A2).
Further, when the power source is lost or the drive circuit of the motor 20 is broken, the manual operation portion 27b of the lock member 27 is operated, and the output portion 27a of the lock member 27 is moved backward from the protruding position shown in FIG. 4A as shown in FIG. 4B. The fuel lid can be unlocked by moving it straight to the position.
The grease stored in the grease storage portion 27h is spread between the output portion 27a and the inner wall of the first cylindrical portion 30b by the advancement and retraction of the lock member 27 by the motor 20 or the manual operation portion 27b. The gap between the output portion 27a and the first cylindrical portion 30b is filled with grease. In addition, since a plurality of grease storage portions 27h are provided along the moving direction of the output portion 27a, the grease spreads over almost the entire gap between the output portion 27a and the first cylindrical portion 30b. Therefore, even if a water droplet adheres to a portion protruding from the guide member 30 of the output portion 27a, it is possible to prevent the water droplet from entering from the gap between the output portion 27a and the first cylindrical portion 30b. Therefore, it is possible to prevent malfunction of the lock member 27 due to freezing of water droplets.
Specifically, when the lock member 27 moves backward, the grease moves along the inner peripheral surface of the first cylindrical portion 30b. If the guide is released by the stepped portion 30g, does the grease adhere to the output portion 27a side? Then, it adheres to the edge of the step portion 30g and stays on the step portion 30g. The grease adhering to the output portion 27a side and the grease accumulated in the step portion 30g are inserted into the first cylindrical portion 30b again by the movement of the lock member 27 in the protruding direction. Therefore, it is possible to spread grease over almost the entire gap between the output portion 27a and the first cylindrical portion 30b, and to prevent the grease from flowing out. Further, even if the viscosity of the grease decreases due to heat or the like, the grease can be prevented from flowing out by the grease storage portion 27h provided in the output portion 27a. Therefore, the waterproof effect can be exhibited over a long period of time.
Moreover, in this embodiment, since the sealing member 28 is arrange | positioned in the outer periphery of the press-contact part 27g behind the output part 27a, the double waterproof effect can be exhibited with grease and the sealing member 28. Further, the seal member 28 can prevent the grease from flowing out to the rear end side of the lock member 27. Therefore, the waterproof effect can be maintained for a long time also from this point.
Moreover, in this embodiment, since the grease accommodating part 27h is provided in the output part 27a, since the structure of the guide member 30 and the lock member 27 can be simplified, manufacturing cost can be reduced. Moreover, since the grease storage portion 27h is provided at a position where it does not protrude from the guide member 30 when the lock member 27 is in the protruding position, the strength of the portion where a load may be applied during the locking of the fuel lid is maintained. However, it is possible to prevent malfunction due to freezing of water droplets. Specifically, the lock member 27 is in the protruding position for locking the fuel lid for most of the normal use of the vehicle, and the lock member 27 is displaced to the retracted position for a very limited time such as during refueling. Therefore, it is unlikely that water droplets that have entered between the lock member 27 and the guide member 30 in the retracted position will freeze, and the possibility of malfunctions occurring in the retracted position is low. Considering this, by providing the grease storage portion 27h at a position that does not protrude from the guide member 30 of the lock member 27, it is possible to prevent malfunctions while maintaining the strength of the output portion 27a.
In addition, this invention is not limited to the structure of the said embodiment, A various change is possible.
For example, although the grease storage portion 27 h is provided in the output portion 27 a of the lock member 27, it may be provided on the inner surface side of the first cylindrical portion 30 b of the guide member 30. Further, although the grease storage portion 27h is provided at a position that does not protrude from the guide member 30 when the output portion 27a is at the protruding position, it may be provided at a protruding position. Moreover, although the plurality of grease storage portions 27h are provided in the moving direction of the output portion 27a, only one or a long one in the axial direction may be provided. In addition, when the lock member 27 is in the protruding position, a plurality of the grease storage portions 27h are provided over almost the entire area between the output portion 27a and the first cylindrical portion 30b, but the output portion 27a and the first cylinder are provided. You may provide only in the partial range of the advancing / retreating direction between the shape parts 30b. In that case, it is more effective to provide the grease storage portion 27h on the front side (opening side) between the output portion 27a and the first cylindrical portion 30b.
Further, the output portion 27a of the lock member 27 is stored in the guide member 30 at the retracted position, but protrudes from the guide member 30 if the engagement with the engagement hole of the fuel lid is released. It may be in the state. Moreover, although the 1st cylindrical part 30b of the guide member 30 was set as the structure protruded from the opening part 12k of the casing 11, it is good also as a structure which does not protrude (buried). Even in this case, the output portion 27a of the lock member 27 may be stored in the opening portion 12k in the retracted position, or if the engagement with the engagement hole of the fuel lid is released, the opening portion 27a is opened. The state which protruded from the part 12k may be sufficient.
Although the present invention has been described by taking the fuel lid lock device as an example, the present invention can also be applied to vehicle actuators other than the fuel lid lock device.
