Description

[Technical Field]

[0001] The present invention relates to a hood lock device that is engageable with a striker provided on a vehicle hood and that keeps the hood closed. [Background technology]

[0002] A hood locking device has been known that includes a primary latch that holds the hood in a fully closed state and a secondary latch that holds the hood in a half-open state. The secondary latch is provided with a handle, and when the handle is operated from the half-open state of the hood, the engagement between the secondary latch and the striker is released, allowing the hood to be fully opened (for example, Patent Documents 1 and 2).

[0003] From the perspective of improving the operability of the hood lock device, Patent Document 1 places two washers in the bearing portion of the shaft that attaches the hook lever (secondary latch) to the base member, allowing the hook lever to rotate with little resistance. Furthermore, Patent Document 2 describes a hook lever that consists of a metal hook and a synthetic resin lever, with the synthetic resin lever positioned between the metal base and the metal hook. This prevents direct contact between the metals, allowing the hook lever to rotate smoothly. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 2558303 [Patent Document 2] Japanese Patent Application Publication No. 8-60918 Summary of the Invention [Problem to be solved by the invention]

[0005] In hood locking devices such as those disclosed in Patent Documents 1 and 2, when used over a long period of time, the hook lever can become twisted due to operation, creating a gap near the rotation axis of the hook lever. If foreign matter such as mud or water enters the axis through this gap, the operability of the hook lever deteriorates, leaving room for improvement.

[Figure 7] 10 is a cross-sectional view of the hood lock device 1 of the second modified example taken along the line AA. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] A hood lock device according to one embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Front, rear, left, right, and top and bottom are described according to the state in which the hood lock device is mounted on a vehicle. In the drawings, the front of the vehicle is indicated as Fr, the rear as Rr, the left as L, the right as R, the top as U, and the bottom as D.

[0011] As shown in FIG. 1, the hood locking device 1 is installed, for example, in the engine compartment of a vehicle V, and is provided so as to be engageable with a striker S provided on a hood H in the engine compartment. The hood locking device 1 holds the hood H in a fully closed position by engaging the striker S. The hood locking device 1 is also connected to a release operating means 100 via a cable 101, and allows the hood H to be opened in response to operation of the release operating means 100. The release operating means 100 is, for example, a manual handle provided near the driver's seat of the vehicle V, or an electric actuator.

[0012] 2 to 4, the hood lock device 1 includes a base plate 2, a primary latch 3, a ratchet 4, a secondary latch 5, and a handle 6. Note that the handle 6 is not shown in FIGS. 3 and 4.

[0013] The base plate 2 has a main body 20, which is a metal plate member, and a pair of left and right fixing portions 21 that are fixed to the vehicle body. A striker groove 22 is provided in the main body 20, and the striker S enters the striker groove 22 in response to the closing operation of the hood H, and disengages from the striker groove 22 in response to the opening operation of the hood H.

[0014] The base plate 2 rotatably supports the primary latch 3, the ratchet 4, and the secondary latch 5. More specifically, the base plate 2 is provided with a hole 23 through which a primary latch shaft 30 that supports the primary latch 3 relative to the base plate 2 is inserted, a hole 24 through which a ratchet shaft 40 that supports the ratchet 4 relative to the base plate 2 is inserted, and a hole 25 through which a secondary latch shaft 50 that supports the secondary latch 5 relative to the base plate 2 is inserted. The primary latch shaft 30, the ratchet shaft 40, and the secondary latch shaft 50 extend in the front-to-rear direction, and support the primary latch 3, the ratchet 4, and the secondary latch 5 rotatably relative to the base plate 2 around their respective axes.

[0015] The primary latch 3 is disposed on the rear side of the main body 20 of the base plate 2. The primary latch 3 has a hole 31 through which the primary latch shaft 30 is inserted, a locking groove 32 that locks the striker S, a spring connecting portion 33 that connects to the coil spring 3s (here, a tension coil spring), and an engaging portion 34 that engages with the ratchet 4.

[0016] The primary latch 3 is rotatable about the primary latch shaft 30 between a latched position, in which the striker S is positioned within the locking groove 32, and an unlatched position, in which the striker S is positioned outside the locking groove 32. FIG. 3 shows the primary latch 3 in the latched position, in which the hood H is held in the fully closed position. In FIG. 3, when the primary latch 3 rotates clockwise about the primary latch shaft 30, it moves to the unlatched position. The spring connecting portion 33 is disposed below the hole 31 and extends in the axial direction of the primary latch shaft 30. One end of a coil spring 3s is connected to the spring connecting portion 33, and the other end is connected to the base plate 2. The primary latch 3 is biased toward the unlatched position by the coil spring 3s. When the primary latch 3 is placed in the latched position, the engagement portion 34 engages with the ratchet 4, thereby holding the primary latch 3 in the latched position against the bias of the coil spring 3s.

[0017] The ratchet 4 is disposed on the rear side of the main body 20 of the base plate 2. The ratchet 4 has a hole 41 through which the ratchet shaft 40 is inserted, an engagement portion 42 that engages with the primary latch 3, a spring connecting portion 43 that connects to the coil spring 4s (here, a tension coil spring), and a cable connecting portion 44 that connects to a cable 101 extending from the release operating means 100. The ratchet 4 extends in the vertical direction, and has the hole 41 at its upper end, the spring connecting portion 43 and the cable connecting portion 44 at its lower end, and the engagement portion 42 at its vertical center.

[0018] The spring connecting portion 43 of the ratchet 4 extends in the axial direction of the ratchet shaft 40. One end of a coil spring 4s is connected to the spring connecting portion 43 of the ratchet 4, and the other end is connected to the base plate 2. The ratchet 4 is biased by the coil spring 4s in a direction (locking direction) in which the meshing portion 42 meshes with the primary latch 3. This prevents the primary latch 3 from rotating toward the unlatched position, and the primary latch 3 is held in the latched position. At this time, the striker S is engaged in the deepest part of the striker groove 22, and the hood H is held in the fully closed position.

[0019] The cable connecting portion 44 of the ratchet 4 extends in the axial direction of the ratchet shaft 40. When the release operating means 100 is operated and tension is received from the cable 101, the ratchet 4 is rotated in the direction opposite to the locking direction, and the engagement with the primary latch 3 is released. The primary latch 3, biased by the coil spring 3s, is rotated toward the unlatched position, pushing the striker S toward the opening side of the striker groove 22. As a result, the hood H pops up from the fully closed position to a half-open position, which is slightly open from the fully closed position.

[0020] The secondary latch 5 is disposed on the front side of the main body portion 20 of the base plate 2. The secondary latch 5 engages with the striker S to hold the hood H in a half-open position. The secondary latch 5 has a hole portion 51 through which the secondary latch shaft 50 is inserted, an arm portion 52 extending upward from the hole portion 51 along the striker groove 22, a hook portion 53 provided at the upper end of the arm portion 52, a spring connecting portion 54 connected to the coil spring 5s (here, a torsion coil spring), and an attachment portion 55 to which the handle 6 is attached.

[0021] The mounting portion 55 extends upward from the hole 51 along the striker groove 22 and is provided facing the hook portion 53 across the striker groove 22. The handle 6 extends forward while attached to the mounting portion 55. An operation input unit 61 that receives operation input from a person is provided at the front end of the handle 6.

[0022] The secondary latch 5 is provided to be rotatable about the secondary latch shaft 50 between a standby position in which the hook portion 53 can latch the striker S, and a retracted position in which the hook portion 53 does not latch the striker S. FIG. 4 shows a state in which the secondary latch 5 is in the standby position, in which the hood H is held in a half-open position. When the secondary latch 5 is placed in the standby position, the hook portion 53 is positioned within the movement trajectory of the striker S that accompanies the opening and closing operation of the hood H, and holds the hood H in the half-open position. When the secondary latch 5 is rotated counterclockwise about the secondary latch shaft 50 from the state shown in FIG. 4 to the retracted position, the hook portion 53 is positioned outside the movement trajectory of the striker S, and allows the hood H to be opened to the fully open position.

[0023] One end of the coil spring 5s is connected to the spring connecting portion 54, and the other end is connected to the base plate 2, and the secondary latch 5 is biased by the coil spring 5s in a direction toward the standby position. When an operation to rotate the secondary latch 5 to the retracted position is input to the operation input portion 61 of the handle 6 while the hood H is held in the half-open position, the hook portion 53 retracts from the opening of the striker groove 22, and the engagement between the hook portion 53 and the striker S is released. This allows the hood H to be opened to the fully open position.

[0024] Next, a detailed description will be given of the structure in which the secondary latch 5 is supported on the base plate 2 by the secondary latch shaft 50. In the following description, the direction in which the secondary latch shaft 50 extends (front-rear direction) will be referred to as the axial direction, and the direction perpendicular to the axial direction will be referred to as the radial direction. In Figures 5 to 7, the first washer 7 and the second washer 8 appear to overlap the secondary latch 5, but this is to show the shapes of the first washer 7 and the second washer 8 (i.e., the shapes of the individual components) when it is assumed that they are not in contact with the secondary latch 5 (dashed line); in reality, the first washer 7 and the second washer 8 elastically deform along the secondary latch 5 and come into close contact.

[0025] 5 is a cross-sectional view taken along line AA in FIG. 4, showing a cross-sectional view of the vicinity of the secondary latch shaft 50. The secondary latch 5 is supported on the base plate 2 via the secondary latch shaft 50 with two washers (specifically, a first washer 7 and a second washer 8) interposed therebetween.

[0026] First, the secondary latch shaft 50 will be described. The secondary latch shaft 50 has an insertion portion 50a that is inserted through the hole 51 in the secondary latch 5 and the hole 25 in the base plate 2, and a head portion 50b that is provided at the front end and has a larger diameter than the insertion portion 50a. The head portion 50b faces the front surface of the secondary latch 5 and is large enough to cover the hole 51 in the secondary latch 5. The secondary latch 5 is sandwiched between the head portion 50b and the base plate 2 and supported by the base plate 2.

[0027] The first washer 7 and the second washer 8 are formed of, for example, a resin material, specifically, polyacetal resin (POM resin). By providing the first washer 7 and the second washer 8, resistance during rotation of the secondary latch 5 is reduced, improving the operability of the handle 6. The first washer 7 and the second washer 8 may also be formed of other resin materials or elastic materials such as rubber.

[0028] The first washer 7 is inserted onto the secondary latch shaft 50 and is disposed between the secondary latch 5 and the base plate 2. The first washer 7 also has a cylindrical bushing portion 73 on its inner periphery, and the bushing portion 73 is inserted into the hole 51 of the secondary latch 5. The bushing portion 73 functions as a bearing for the secondary latch shaft 50.

[0029] The second washer 8 is inserted onto the secondary latch shaft 50 and is disposed between the secondary latch 5 and the head 50b. The outer diameter of the second washer 8 is larger than the outer diameter of the head 50b of the secondary latch shaft 50.

[0030] However, because the operation input unit 61 of the handle 6 is positioned offset in the radial and axial directions relative to the secondary latch shaft 50 (see FIG. 2), if the hood locking device 1 is used continuously over a long period of time, the secondary latch 5 may be twisted in the axial direction by operations on the operation input unit 61. If the twisting of the secondary latch 5 causes a gap to form between the secondary latch 5 and the base plate 2 and / or between the secondary latch 5 and the head 50b, foreign matter such as mud or water may enter the insertion portion 50a and hole 51 of the secondary latch shaft 50, which may deteriorate the operability of the hood locking device 1 (specifically, the operability of the handle 6).

[0031] Therefore, the first washer 7 has a first protrusion 71 that protrudes toward the secondary latch 5 radially outward from the hole 51. Similarly, the second washer 8 has a second protrusion 81 that protrudes toward the secondary latch 5 radially outward from the hole 51.

[0032] Because the first washer 7 and the second washer 8 have the first protrusion 71 and the second protrusion 81, respectively, even if the secondary latch 5 is twisted in the axial direction, the first washer 7 and the second washer 8 are disposed in close contact between the secondary latch 5 and the base plate 2 and between the secondary latch 5 and the head 50b, respectively, making it difficult for a gap to form that communicates with the insertion portion 50a of the secondary latch shaft 50. Furthermore, because the first washer 7 and the second washer 8 are provided as separate bodies, even if the first washer 7 and the second washer 8 elastically deform in response to twisting of the secondary latch 5, the deformation of one does not affect the deformation of the other, making it difficult for a gap to form that communicates with the insertion portion 50a of the secondary latch shaft 50. This prevents foreign matter from entering the insertion portion 50a and hole 51 of the secondary latch shaft 50, which could deteriorate the operability of the hood locking device 1. Furthermore, since the first washer 7 and the second washer 8 are provided separately, the hood lock device 1 can be easily assembled.

[0033] Furthermore, since the first protrusion 71 and the second protrusion 81 protrude toward the secondary latch 5, the first washer 7 and the second washer 8 follow the rotation of the secondary latch 5 while maintaining a tight contact state. The second washer 8 also comes into close contact with the secondary latch 5, which has a larger area than the head 50b. Therefore, a gap communicating with the insertion portion 50a of the secondary latch shaft 50 is less likely to occur.

[0034] In this embodiment, the first protrusion 71 and the second protrusion 81 bend and protrude toward the secondary latch 5 at a radially intermediate position between the inner and outer circumferential portions. As a result, even if the secondary latch 5 is twisted, the first washer 7 and the second washer 8 are disposed in close contact with the rear and front surfaces of the secondary latch 5 due to elastic deformation, and can smoothly follow the rotation of the secondary latch 5 while maintaining this close contact state. This makes it more unlikely that a gap communicating with the insertion portion 50a of the secondary latch shaft 50 will occur.

[0035] Furthermore, the first washer 7 has a bushing portion 73 that functions as a bearing, which reduces resistance when the secondary latch 5 rotates. Furthermore, the bushing portion 73 fills the gap between the insertion portion 50a of the secondary latch shaft 50 and the hole 51 of the secondary latch 5, thereby preventing foreign matter from entering the hole 51. Note that, although the first washer 7 has a configuration that includes the bushing portion 73 in this embodiment, this is not limiting, and the second washer 8 may also have a bushing portion, or both the first washer 7 and the second washer 8 may have bushing portions. Furthermore, the first washer 7 and / or the second washer 8 do not necessarily have to have a bushing portion 73.

[0036] The first washer 7 and the second washer 8 are made of a resin material or an elastic member. As a result, the first washer 7 and the second washer 8 have appropriate elasticity, which allows elastic deformation to suppress rattle between the secondary latch 5 and the base plate 2. The first washer and the second washer also have appropriate hardness, which prevents twisting of the secondary latch 5.

[0037] (Variation 1) 6 shows a cross-sectional view of the first washer 7 and the second washer 8 of Modification 1. The first protrusion 71 of the first washer 7 and the second protrusion 81 of the second washer 8 of Modification 1 protrude in a curved manner from the inner periphery to the outer periphery toward the secondary latch 5.

[0038] With this configuration, even if the secondary latch 5 is twisted, the first washer 7 and the second washer 8 are disposed in close contact with the rear and front surfaces of the secondary latch 5 due to elastic deformation, and can smoothly follow the rotation of the secondary latch 5 while maintaining this close contact state. This makes it less likely that a gap will form that communicates with the insertion portion 50a of the secondary latch shaft 50, preventing foreign matter from entering the insertion portion 50a and the hole 51.

[0039] (Variation 2) 7 shows a cross-sectional view of the first washer 7 and the second washer 8 of Modification 2. In Modification 2, the first protrusion 71 of the first washer 7 is provided on the radially outer end of the first washer 7 and is configured as a protrusion that protrudes toward the secondary latch 5. The first washer 7 also has a first inner protrusion 72 that protrudes radially inward from the first protrusion 71 and on the opposite side from the first protrusion 71. The first inner protrusion 72 is configured as a protrusion that protrudes toward the base plate 2 and is in close contact with the base plate 2.

[0040] Similarly, the second protrusion 81 of the second washer 8 is provided on the radially outer end of the second washer 8 and is configured as a protrusion that protrudes toward the secondary latch 5. The second washer 8 also has a second inner protrusion 82 that protrudes radially inward from the second protrusion 81 and on the opposite side from the second protrusion 81. The second inner protrusion 82 protrudes toward the head 50b of the secondary latch shaft 50 and is configured as a protrusion that comes into close contact with the head 50b.

[0041] With this configuration, even if the secondary latch 5 is twisted, a gap communicating with the insertion portion 50a of the secondary latch shaft 50 is unlikely to occur, and entry of foreign matter can be prevented.

[0042] Although one embodiment and modifications of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such embodiments. It is clear that a person skilled in the art can conceive of various modifications or alterations within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention. Furthermore, the components of the above-described embodiments may be combined in any manner without departing from the spirit of the invention.

[0043] For example, in the above-described embodiment, the first protruding portion 71 of the first washer 7 and the second protruding portion 81 of the second washer 8 each protrude toward the secondary latch 5, but this is not limited thereto. For example, the first protruding portion 71 may protrude toward the base plate 2 and / or the second protruding portion 81 may protrude toward the head 50b of the secondary latch shaft 50. Even with this configuration, the first washer 7 and the second washer 8 are disposed in close contact between the secondary latch 5 and the base plate 2 and between the secondary latch 5 and the head 50b, respectively, so that gaps communicating with the insertion portion 50a are unlikely to occur.

[0044] Furthermore, a first washer 7 having a first protrusion 71 and a second washer 8 having a second protrusion 81 may be provided for the primary latch shaft 30 and / or the ratchet shaft 40.

[0045] This specification describes at least the following: In parentheses, components corresponding to those in the above-described embodiments are shown as examples, but the present invention is not limited to these.

[0046] (1) A hood locking device (hood locking device 1) that is engageable with a striker (striker S) provided on a hood (hood H) of a vehicle (vehicle V) and that keeps the hood closed, a base plate (base plate 2) fixed to the vehicle body and having a striker groove (striker groove 22) through which the striker can advance and retreat; a latch (secondary latch 5) that holds the striker that has entered the striker groove in a predetermined position (half-open position); a shaft portion (secondary latch shaft 50) having a head portion (head portion 50b) that is inserted into holes (hole portion 25, hole portion 51) formed in the latch and the base plate to support the latch rotatably relative to the base plate and that holds the latch between itself and the base plate; a first washer (first washer 7) inserted through the shaft portion and disposed between the latch and the base plate; a second washer (second washer 8) inserted through the shaft portion and disposed between the latch and the head portion of the shaft portion; the first washer has a first protruding portion (first protruding portion 71) that protrudes toward the latch or the base plate on a radially outer side of the shaft portion than the hole portion, The second washer has a second protruding portion (second protruding portion 81) that protrudes toward the latch or the head portion on the outer side of the hole in the radial direction. Hood lock device.

[0047] According to (1), because the first washer and the second washer have a first protrusion and a second protrusion, respectively, even if the latch is twisted axially by operating the hood locking device, the first washer and the second washer are positioned closely between the latch and the base plate and between the latch and the head of the shaft, respectively, making it difficult for a gap to form through the shaft. Furthermore, because the first washer and the second washer are provided separately, even if the first washer and the second washer deform in response to twisting of the latch, the deformation of one does not affect the deformation of the other, making it difficult for a gap to form through the shaft. This prevents foreign matter (mud, water, etc.) from entering the shaft and hole, which could degrade the operability of the hood locking device.

[0048] (2) The hood lock device according to (1), the first protrusion and the second protrusion protrude toward the latch on the outer side of the hole in the radial direction; Hood lock device.

[0049] According to (2), even if the latch is twisted in the axial direction, the first washer and the second washer are arranged in close contact with the latch and can follow the rotation of the latch while maintaining close contact. This makes it less likely that a gap will be formed that connects to the shaft, and foreign matter can be more effectively prevented from entering the shaft and the hole. In addition, because the second washer protrudes toward the latch, which has a larger area than the head, it is even less likely that a gap will be formed that connects to the shaft.

[0050] (3) The hood lock device according to (1) or (2), At least one of the first washer and the second washer has a cylindrical bush portion (bush portion 73) that is inserted into the hole portion. Hood lock device.

[0051] According to (3), by inserting the bushing into the hole, it is possible to prevent foreign matter from entering the hole.

[0052] (4) A hood lock device according to any one of (1) to (3), The first washer and the second washer are formed of a resin material or an elastic material. Hood lock device.

[0053] According to (4), the first and second washers have appropriate elasticity, which can suppress rattle between the latch and the base plate through elastic deformation. In addition, the first and second washers have appropriate hardness, which can suppress twisting of the latch, improving the operability of the hood lock device.

[0054] (5) A hood lock device according to any one of (1) to (4), the first protrusion protrudes in a bent or curved manner toward the latch or the base plate on an outer side of the hole in the radial direction, The second protrusion protrudes in a bent or curved manner toward the latch or the head portion on the outer side of the hole in the radial direction. Hood lock device.

[0055] According to (5), even if the latch is twisted in the axial direction, the first washer and the second washer are disposed in close contact with the latch due to elastic deformation, and can smoothly follow the rotation of the latch while maintaining the close contact state. This makes it difficult for a gap communicating with the shaft portion to occur.

[0056] (6) A hood lock device according to any one of (1) to (4), The first washer further includes a first inner protruding portion (first inner protruding portion 72) that protrudes inwardly of the first protruding portion in the radial direction and in a direction opposite to the first protruding portion, The second washer further has a second inner protruding portion (second inner protruding portion 82) that protrudes inwardly of the second protruding portion in the radial direction and in a direction opposite to the second protruding portion. Hood lock device.

[0057] According to (6), even if the latch is twisted in the axial direction, each washer is positioned in close contact with the latch by the two protrusions, and can smoothly follow the rotation of the latch while maintaining close contact. This makes it difficult for gaps to form in the shaft.

[0058] (7) A hood lock device according to any one of (1) to (6), a primary latch (primary latch 3) that is rotatably supported on the base plate and that holds the hood in a fully open position by engaging with the striker that has entered the striker groove; a secondary latch (secondary latch 5) that is rotatably supported on the base plate and engages with the striker that has entered the striker groove to hold the hood in a half-open position that is slightly more open than the fully-open position, The secondary latch is provided with a handle (handle 6) that can rotate the secondary latch in a direction to release the engagement with the striker, The first washer and the second washer are inserted onto the shaft portion (secondary latch shaft 50) of the secondary latch. Hood lock device.

[0059] According to (7), by providing the first washer and the second washer with protrusions on the secondary latch, which is prone to twisting when the handle is operated, it is possible to prevent deterioration in the operability of the handle. [Explanation of symbols]
