Description

Technical Field

[0001] The present invention relates to a locking device for a vehicle. Background Art

[0002] Conventionally, there is a vehicle locking device (vehicle hood lock (hoodlock) device) in which, for example, a torsion spring is engaged with a latch in contact with a lock catch (see Patent Document 1). The vehicle locking device includes: a latch that rotates between a restraining position for restraining the lock catch and a releasing position for releasing the lock catch; a lock lever that holds the latch in the restraining position; and a torsion spring, one end of which is engaged with the latch and applies elastic force to the latch in the direction of the release position. In the vehicle locking device, by engaging one end of the torsion spring with the latch, the lock catch can be pushed up via the latch when the hood is opened, and the latch can be rotated to the release position when the hood is opened, using the elastic force of the torsion spring. That is, in the vehicle locking device, the lock catch can be pushed up and the latch can be rotated using a single torsion spring, so the number of components of the vehicle locking device can be reduced.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2020-165086 Summary of the invention

[0006] Problem that the invention aims to solve

[0007] However, in the above-mentioned conventional vehicle locking device, when the hood is pushed up by the torsion spring (when the hood is opened) or when the hood is pressed down against the torsion spring (when the hood is closed), sliding resistance (for example, sliding resistance caused by sliding between the spring hole formed in the latch and one end of the torsion spring connected to the spring hole) is generated at the engagement portion between the latch and the torsion spring. Therefore, the force of pushing up or pressing down the hood is correspondingly lost due to the sliding resistance (sliding loss is generated).

[0008] Therefore, an object of the present invention is to provide a vehicle locking device capable of suppressing the loss of the pushing-up force or the pressing-down force of a cover body.

DETAILED DESCRIPTION

[0024] Hereinafter, a vehicle locking device according to an embodiment of the present invention will be described with reference to the accompanying drawings. The vehicle locking device is arranged at an opening for an engine room provided in front of a vehicle (body), and locks a bonnet (lid body) that opens and closes the opening in a closed state. In addition, the vehicle locking device has: a locking function that constrains a latch fixed to the bonnet and locks the bonnet in a closed state; and a pushing function that pushes up the latch and pushes the bonnet open. In particular, the vehicle locking device has a bonnet pushing-up structure that can reduce the loss of the bonnet pushing-up force or the pressing force. In addition, the left and right, front and back, and up and down are defined as shown in the respective figures for description. Specifically, the entry direction of the latch is set as the up and down direction, the direction orthogonal to the up and down direction is set as the left and right direction, and the direction orthogonal to the up and down direction and the left and right direction is set as the front and back direction. In the present embodiment, for example, the up and down direction of the vehicle locking device is consistent with the up and down direction of the vehicle, the left and right direction of the vehicle locking device is consistent with the vehicle width direction of the vehicle, and the front and back direction of the vehicle locking device is consistent with the front and back direction of the vehicle.

[0025] (Implementation Method)

[0026] like Figure 1As shown, the vehicle locking device 1 comprises: a base 11, which is formed with an entry groove 22 for a striker S to enter; a hook-shaped latch 12, which is supported on the right side of the front surface of the base 11 so as to be swingable, and constrains the striker S; a locking rod 13 (pole: rod), which is supported on the left side of the front surface of the base 11 so as to be swingable, and locks the latch 12; and a torsion spring 14, which is adjacently arranged in front of the latch 12 and pushes the striker S to the rear in the entry direction D. The latch 12 is supported by a latch pin 15 constituting a swing axis so as to be swingable relative to the base 11 at a constraining position A1 (refer to Figure 1 (b)) and the release position A2 (refer to Figure 1 In addition, the lock lever 13 is supported by the lock pin 16 constituting the swing axis so as to be swingable relative to the base 11 at the lock position B1 (refer to Figure 1 (b)) and the unlocked position B2 where the latch 12 is unlocked (refer to Figure 6 (a) between.

[0027] like Figure 1 As shown, the base 11 is formed of a metal plate and has: a plate-shaped flat plate portion 21; an entry groove 22 formed in the left-right center of the flat plate portion 21; a right rising portion 24 and a left rising portion 25, which rise in a manner of expanding from the left and right ends of the flat plate portion 21 to the rear; a right flange portion 26 extending from the top end of the right rising portion 24 in the right direction and having a right mounting hole 26a; and a left flange portion 27 extending from the top end of the left rising portion 25 in the left direction and having a left mounting hole 27a. The base 11 is fixed to the vehicle body by screwing at two locations of the right mounting hole 26a and the left mounting hole 27a.

[0028] The entry groove 22 is an opening extending downward from the upper end of the flat plate portion 21, and is formed into a "U"-shaped groove from the front, with the upper end side as the open side and the lower side as the bottom side. In addition, the entry groove 22 has a width that the lock buckle S can pass through, and functions as a lock buckle guide to guide the lock buckle S. In addition, the lock buckle S has a cylindrical engaging portion S1 and a pair of arm portions S2 that support the cylindrical engaging portion S1 in a double-armed manner. The entry groove 22 contacts the cylindrical engaging portion S1 to guide the lock buckle S.

[0029] like Figure 1 and Figure 2As shown, the latch 12 is formed by a plate-shaped and "U"-shaped metal component, and integrally comprises: a main body 31, which is assembled to be able to swing freely relative to the latch pin 15; a first claw 32, which extends in the left direction from the main body 31 across the entry groove 22, and contacts the lock S from below; a second claw 33, which extends in the upper left direction from the main body 31 in a manner facing the first claw 32, and contacts the cylindrical engaging portion S1 of the lock S from above; an engaged claw 34, which is formed at the top end of the first claw 32 and engages with the locking rod 13; and an engaged rib 35 (engaged portion), which is formed in a manner of standing up forward from the upper right end of the main body 31, and engages with the torsion spring 14.

[0030] A restraining groove 36 for restraining the lock catch S is formed between the first claw portion 32 and the second claw portion 33. When the latch 12 is swung to the restraining position A1, the restraining groove 36 faces leftward, and correspondingly, when the latch 12 is swung to the releasing position A2, the open side of the restraining groove 36 faces upward, and the lock catch S moving on the entry groove 22 enters the inside of the restraining groove 36.

[0031] The upper end surface 32a of the first claw portion 32 is a contact surface (receiving surface) that contacts the cylindrical engaging portion S1 of the lock catch S, and functions as a pressure receiving portion that receives the pressure from the lock catch S moving on the entry groove 22 from above. On the other hand, the lower end surface of the second claw portion 33 is a pressure suppressing surface that suppresses the cylindrical engaging portion S1 of the lock catch S from above, and when the latch 12 is swung to the restrained position A1, it serves as a limit and suppresses the lock catch S from entering the direction D (refer to Figure 1 (b)) The movable suppression part at the rear functions.

[0032] The engaged rib 35 is a rib formed in a manner of standing forward from the main body 31, and contacts and engages with the first arm portion 52 of the torsion spring 14 from the upper right oblique side. The engaged rib 35 engages with the first arm portion 52 from the front side of the winding direction of the torsion spring 14 (the counterclockwise rotation side of the circumferential direction of the torsion spring 14 when viewed from the front), and transmits the force of the torsion spring 14 to the latch 12. The latch 12 is urged toward the release position A2 by the force of the torsion spring 14. In addition, the engaged rib 35 can be said to contact and engage with the first arm portion 52 on the front side of the rotation direction of the first arm portion 52 when the lock catch S presses the first arm portion 52. Although the details will be described later, by this structure, when the lock catch S presses the first arm portion 52 in the entry direction D, the engagement between the engaged rib 35 and the first arm portion 52 is released.

[0033] like Figure 1As shown, the locking lever 13 is formed by a plate-shaped metal member extending in the up-down direction, and integrally comprises: a main body 41, which is supported to swing freely relative to the locking pin 16 and extends in the up-down direction; an engaging claw 42, which is formed on the right side of the lower end portion of the main body 41 and engages with the engaged claw 34 of the latch 12; a spring engaging portion 43, which is formed at the upper end portion of the main body 41 and engages with the second arm portion 53 of the torsion spring 14; a downward extending portion 44, which extends downward from the lower end portion of the main body 41; and an operating portion 45, which is formed on the right side of the base end portion of the downward extending portion 44 and is operated by a release cable not shown in the figure.

[0034] When the lock lever 13 is swung to the locked position B1, the engaging claw 42 engages with the engaged claw 34 of the latch 12 that is swung to the restrained position A1, and the latch 12 is locked (held) at the restrained position A1. On the other hand, when the lock lever 13 is swung to the unlocked position B2, the engagement between the engaged claw 34 and the engaging claw 42 is released, and the locking of the latch 12 is released. In addition, the swing from the locked position B1 to the unlocked position B2 is performed by operating the operating part 45 by the release cable. On the other hand, when the release cable is not operated, the force of the torsion spring 14 is transmitted to the lock lever 13 via the second arm 53, and the lock lever 13 is swung to the locked position B1. In addition, the upper end surface of the engaging claw 42 is an induction slope that is inclined downward toward the right side. When the latch 12 is swung from the release position A2 to the restrained position A1 when the lock lever 13 is located at the locked position B1, the induction slope contacts the latch 12, and the lock lever 13 swings to the unlocked position B2 side. This provides a structure that allows the latch 12 to swing toward the restraint position A1.

[0035] like Figure 1 and Figure 3 As shown in the figure, the torsion spring 14 is wound around the latch pin 15 and has a winding portion 51 formed by winding a metal wire, a first arm portion 52 on the rear side formed by leading the metal wire from one end of the winding portion 51, and a second arm portion 53 on the front side formed by leading the metal wire from the other end of the winding portion 51. Specifically, the torsion spring 14 is inserted through the shaft portion 15b of the latch pin 15 and is arranged between the head portion 15a of the latch pin 15 and the latch 12, and is arranged adjacent to the front side of the latch 12 so that the first arm portion 52 is located on the latch 12 side.

[0036] The second arm portion 53 includes a leftward extending portion 61 extending from the lower portion of the winding portion 51 in the left direction, and a rod engaging portion 62 bent (curved) from the top end of the leftward extending portion 61 and extending obliquely to the left and upward, and engaging with the spring engaging portion 43 of the lock lever 13. The torsion spring 14 engages with the spring engaging portion 43 of the lock lever 13 via the rod engaging portion 62 of the second arm portion 53, and urges the lock lever 13 to the lock position B1.

[0037] The first arm 52 includes a latch engaging portion 71 that extends obliquely upward to the left after being drawn upward from the right portion of the winding portion 51 and engages with the engaged rib 35 of the latch 12, and a lock contact portion 72 that is connected to the top end side of the latch engaging portion 71 and extends in the left direction in a manner that crosses the entry groove 22 and contacts the lock S. The torsion spring 14 engages with the engaged rib 35 of the latch 12 through the latch engaging portion 71 of the first arm 52, and applies elastic force to the latch 12 toward the release position A2. In addition, the torsion spring 14 presses and contacts with the cylindrical engaging portion S1 of the lock S through the lock contact portion 72 of the first arm 52, and applies force to the lock S to the rear (upward) in the entry direction D.

[0038] In addition, the first arm 52 is configured so that when the latch S is pressed downward (in the entry direction D of the latch S), the engagement between the latch engaging portion 71 and the engaged rib 35 is released. That is, when the first arm 52 is pressed downward by the latch S, the engagement between the latch engaging portion 71 and the engaged rib 35 is released, and the torsion spring 14 applies force only to the latch S among the latch S and the latch 12. On the other hand, when the hood (not shown) is opened and the first arm 52 is not pressed downward by the latch S, the latch engaging portion 71 is engaged with the engaged rib 35, and the torsion spring 14 applies force to the latch 12. That is, regardless of whether the latch S is in contact with the first arm 52, when the first arm 52 is not pressed downward by the latch S, the latch engaging portion 71 is engaged with the engaged rib 35, and the latch 12 is applied force.

[0039] (Operation of the vehicle locking device)

[0040] Next, refer to Figures 4 to 6 The following describes the hood closing action (hood closing method) and hood opening action (hood opening method) of the vehicle locking device 1. Figures 4 to 6 In the figure, the wrist portion S2 near the front side of the buckle S is omitted.

[0041] First, refer to Figure 4 and Figure 5 The hood closing action in the vehicle locking device 1 is described below. The hood closing action is performed by the user dropping the top side of the hood from above, and is performed by the vehicle locking device 1 to constrain the latch S of the closed hood and lock (hold) the hood in a closed state. In addition, the hood closing action is performed from a state where the latch 12 swings to the release position A2 and the locking rod 13 swings to the locking position B1 due to the force of the torsion spring 14. In addition, in the state before the hood closing action is performed (the state where the latch 12 is separated from the latch S), the first arm portion 52 of the torsion spring 14 is engaged with the engaged rib 35 of the latch 12, and the latch 12 is in a state where a force is applied to the release position A2.

[0042] like Figure 4 As shown in (a), when the hood is continuously closed due to the fall of the top side of the hood, first, the lock S enters the entry groove 22, and the cylindrical engaging portion S1 of the lock S contacts the first arm portion 52 (lock contact portion 72) of the torsion spring 14. Since the first arm portion 52 of the torsion spring 14 is arranged above the first claw portion 32 of the latch 12, the cylindrical engaging portion S1 of the lock S contacts the first arm portion 52 first.

[0043] Afterwards, when the closing of the engine hood continues further, the lock catch S moves forward on the entry groove 22, as shown in FIG. Figure 4 As shown in (b), the first arm 52 is pressed downward by the lock catch S, and the first arm 52 rotates downward. Due to the rotation of the first arm 52, the engagement between the latch engaging portion 71 of the first arm 52 and the engaged rib 35 of the latch 12 is released. Thereafter, the lock catch S contacts the first claw portion 32 of the latch 12.

[0044] Afterwards, when the closing of the engine hood continues further, the lock catch S moves forward on the entry groove 22, as shown in FIG. Figure 4 As shown in (c), the first arm 52 continues to rotate, and due to the pressing of the lock catch S, the latch 12 continues to swing toward the restraining position A1. As a result, the cylindrical engaging portion S1 of the lock catch S enters the restraining groove 36 of the latch 12. After that, the hood is further closed, as shown in FIG. Figure 5 As shown in (d), when the latch 12 reaches the restraining position A1, the engaged claw 34 of the latch 12 engages with the engaging claw 42 of the locking rod 13, and the latch 12 is locked at the restraining position A1. Thus, the latch 12 locked at the restraining position A1 restrains the striker S, and the engine hood after the striker S is fixed can be locked in the closed state.

[0045] Afterwards, if Figure 5 As shown in (e), the first arm portion 52 of the torsion spring 14 presses the cylindrical engagement portion S1 of the striker S against the second claw portion 33 of the latch 12. In this way, the torsion spring 14 functions as a buffer for pressing the striker S against the second claw portion 33. Thus, the hood closing action is terminated.

[0046] Next, refer to Figure 6 The hood opening action in the vehicle locking device 1 is described. The hood opening action is an action performed by the user operating the operating portion 45 by releasing the cable, and the vehicle locking device 1 pushes the lock S upward to push the hood open. Figure 5 The latch 12 is locked at the restraining position A1 by the lock rod 13 and the striker S is restrained by the latch 12 locked at the restraining position A1 as shown in (e).

[0047] like Figure 6 As shown in (a), when the user operates the operating part 45 by releasing the cable, the locking lever 13 swings from the locking position B1 to the unlocking position B2, and the locking of the latch 12 by the locking lever 13 is released. When the latch 12 is unlocked, the lock catch S is pushed upward by the first arm 52 due to the force of the torsion spring 14, and the latch 12 whose second claw 33 contacts the cylindrical engaging part S1 of the lock catch S continuously swings toward the release position A2 side.

[0048] Afterwards, if Figure 6 As shown in (b), after the latch 12 is swung so that the restraining groove 36 faces upward due to the push of the lock catch S, the cylindrical engaging portion S1 of the lock catch S is disengaged from the restraining groove 36. Figure 6 As shown in (c), due to the force of the torsion spring 14, the lock S bounces upward and the engine hood is pushed open. At this time, the first arm 52 of the torsion spring 14 returns to the state before being pressed down, and the first arm 52 (latch engagement portion 71) engages with the engaged rib 35 of the latch 12. Due to this engagement, the latch 12 is urged toward the release position A2 by the force of the torsion spring 14, and the position of the latch 12 is maintained at the release position A2. Thus, the engine hood opening action is terminated.

[0049] (Functions and Effects of Implementation Methods)

[0050] As described above, according to the configuration of the above-mentioned embodiment, since the first arm portion 52 is configured to have the torsion spring 14 that contacts the striker S and engages with the latch 12, when the first arm portion 52 is pressed down by the striker S, the engagement between the latch 12 and the torsion spring 14 is released. Therefore, when the hood is pushed up via the striker S by the torsion spring 14 or when the hood is pressed down against the torsion spring 14, the latch 12 and the torsion spring 14 are not engaged. Therefore, when the hood is pushed up and pressed down, no sliding resistance is generated at the engaging portion between the latch 12 and the torsion spring 14, and the loss of the pushing up force and the pressing down force of the hood can be suppressed. As a result, the force required when pushing up the hood (when the hood is opened) or the force required when pressing down the hood (when the hood is closed) can be reduced. In particular, since the force required when pushing up the hood is reduced, a small torsion spring 14 with a small spring force (elastic force, spring constant) can be selected. Therefore, it is possible to achieve weight reduction, size reduction, and cost reduction of the vehicle locking device 1 .

[0051] In addition, according to the configuration of the above-mentioned embodiment, since the engine hood is pushed up through the striker S and the latch 12 is forced to rotate toward the release position A2 by a single torsion spring 14, the number of components of the vehicle locking device 1 can be reduced, and the vehicle locking device 1 can be made into a simple configuration. In addition, in the above-mentioned embodiment, the torsion spring 14 also functions as a buffer member that presses the striker S against the second claw portion 33 when the striker S is restrained to prevent the occurrence of rattling noise. Therefore, compared with providing a buffer member separately, the number of components of the vehicle locking device 1 can be reduced, and the vehicle locking device 1 can be made into a simpler configuration.

[0052] In addition, according to the configuration of the above-mentioned embodiment, as an engagement release structure for disengaging the first arm portion 52 from the latch 12 when the first arm portion 52 is pressed down by the lock S, there is an engaged portion (engaged rib 35) that contacts and engages with the first arm portion 52 on the near front side of the rotation direction of the first arm portion 52 when the lock S presses the first arm portion 52, thereby enabling the above-mentioned engagement release structure to be realized with a simple configuration.

[0053] (Regarding other embodiments)

[0054] The above describes the embodiments of the present invention, but the above embodiments do not limit the invention involved in the claims. In addition, it should be noted that all combinations of the features described in the embodiments are not necessarily required for the solution to the problem of the invention. In addition, the present invention can be appropriately modified and implemented within the scope of its purpose.

[0055] For example, in the above-mentioned embodiment, the engaged rib 35 is configured to contact the first arm portion 52 in the radial direction of the winding portion 51, but the present invention is not limited thereto, and any configuration is sufficient as long as the engaged rib 35 contacts the first arm portion 52 near the front side in the rotation direction when the lock S presses the first arm portion 52 down. Figure 7 As shown in the figure, a portion of the first arm portion 52 (latch engaging portion 71) is extended in the radial direction of the winding portion 51, and the engaged rib 35 contacts the portion in the circumferential direction of the winding portion 51. In this case, as shown in the figure, it is preferable to form a leftward extending portion 81 extending in the left direction from the top end portion of the engaged rib 35.

[0056] In the above embodiment, the latch 12 includes a rib (engaged rib 35) that is engaged with the first arm 52 of the torsion spring 14, but the present invention is not limited thereto. Figure 8 As shown, in the main body 31 of the latch 12, the engaged portion is constituted by an engaged protrusion 82 which is a protrusion formed of a pin or the like.

[0057] In the above embodiment, the lock contact portion 72 is formed straight (linearly), but the present invention is not limited thereto. That is, the lock contact portion 72 may be formed in a curved manner. For example, Fig. 9 As shown, the first arm portion 52 is bent (or curved) in such a manner that the normal direction at the position where the latch S contacts is consistent with the entry direction D of the latch S when the latch S presses down the first arm portion 52 and when the latch S does not press down the first arm portion 52. According to this structure, when the engine hood is pushed up or pressed down, no component force in the left and right directions is generated between the latch S and the first arm portion 52, so the loss of the pushing force and pressing force of the engine hood can be further suppressed. In addition, Fig. 9 In the example, Fig. 9 (a) state and Fig. 9 In the two states of state (b), the normal direction of the position where the lock S contacts is consistent with the entry direction D of the lock S, but the first arm portion 52 can also be formed in a curved manner in such a way that the normal direction of the position where the lock S contacts is consistent with the entry direction D of the lock S in each state when the first arm portion 52 is continuously pressed down.

[0058] In addition, in the above-mentioned embodiment, the present invention is applied to the vehicle locking device 1 for locking the engine room hood (engine hood) in the closed state, but it is not limited to this, and the present invention can also be applied to the vehicle locking device for locking the luggage compartment hood (trunk cover) in the closed state. Further, as long as it is a vehicle locking device for locking a cover body that opens and closes an opening provided in a vehicle body in the closed state, for example, the present invention can also be applied to a vehicle locking device for locking a cover body that opens and closes an opening for charging (so-called charging cover) in the closed state.

[0059] In addition, in the above embodiment, the lock S is fixed to the engine hood (cover) side and the vehicle locking device 1 is fixed to the opening side, but the vehicle locking device 1 may be fixed to the engine hood (cover) side and the lock S is fixed to the opening side.

[0060] In addition, although the description is omitted in the above embodiment, the vehicle locking device 1 may also be configured to further include a safety lever that stops the hood to be opened in a slightly opened half-open state. In this case, the expressions such as opening, opening, and opening state of the hood in the above embodiment include half-opening, half-opening, and half-opening state of the hood.
