Japanese Patent Application No. 2013-166017

(Problems to be solved by the invention)
On the other hand, when designing this type of door lock device, a water guiding structure is provided to more reliably prevent water from flowing into openings formed in the protective member 20 such as the cable lead-out openings 20a and 20b. There is a demand for improving the effect of preventing flooding of the opening by further improving the above.

  One of the objects of the present invention is to provide a technique effective in enhancing the effect of preventing flooding of the opening formed in the protective member in the vehicle door lock device in which the protective member is attached to the housing. .

The water guiding structure includes water guiding ribs and interference walls. The water guide rib is erected in a long shape along the front-rear direction of the housing on the outer surface of the housing in order to guide water that has entered the vehicle door to a predetermined water guide region. Thereby, the water that has entered the vehicle door is guided to the water guiding area by the water guiding rib. The interference wall is interposed along the vertical direction of the housing between the water guide rib and the opening of the protection member, and interferes with the flow of water from the water guide region toward the opening. Thereby, the flow of water from the water guiding region to the opening can be blocked by the interference wall and disturbed, and water does not easily enter the opening. As a result, it is possible to enhance the effect of preventing flooding of the opening of the protective member. Moreover, a protection member is provided with the opposing wall arrange | positioned facing the rib lower surface of a water guidance rib. This opposing wall is located in a separation region where the wall height in the standing height direction of the water guiding rib is lower than the standing height of the water guiding rib in the proximity region close to the lower surface of the rib and is spaced downward from the proximity region. It is configured to gradually increase as it goes and to exceed the standing height of the water guide rib in the separation region. In this case, the water that has flowed down the housing beyond the water guiding rib flows along the opposing wall. At this time, since the wall height of the adjacent region is relatively low in the opposing wall, water is easily guided downward beyond the boundary between the lower surface of the water guiding rib and the adjacent region of the opposing wall. As a result, it is possible to prevent water from entering from the boundary between the lower surface of the water guiding rib and the adjacent region of the opposing wall. That is, the opposing wall has a function of smoothly flowing down water that does not enter the housing side while flowing away from the original guide path of the water guide rib.

  The water guiding structure includes water guiding ribs and interference walls. The water guide rib is erected in a long shape along the front-rear direction of the housing on the outer surface of the housing in order to guide the water that has entered the vehicle door to a predetermined water guide region. Thereby, the water that has entered the vehicle door is guided to the water guiding area by the water guiding rib. The interference wall is interposed along the vertical direction of the housing between the water guide rib and the opening of the protection member, and interferes with the flow of water from the water guide region toward the opening. Thereby, the flow of water from the water guiding region to the opening can be blocked by the interference wall and disturbed, and water does not easily enter the opening. As a result, it is possible to enhance the effect of preventing flooding with respect to the opening of the protective member.

  In the above-described vehicle door lock device, it is preferable that the interference wall guides the water guided to the water guide region in a direction further away from the opening. Thereby, the water induced | guided | derived to the water guidance area | region can be kept away from an opening part, and the flooding prevention effect with respect to the opening part of a protection member can further be heightened.

  In the vehicle door lock device described above, it is preferable that the protection member includes a facing wall that is disposed to face the rib lower surface of the water guiding rib. This opposing wall is located in a separation region where the wall height in the standing height direction of the water guiding rib is lower than the standing height of the water guiding rib in the proximity region close to the lower surface of the rib and is spaced downward from the proximity region. It is preferable to be configured so as to gradually decrease as it goes and to exceed the standing height of the water guide rib in the separation region. In this case, the water that has flowed down the housing beyond the water guiding rib flows along the opposing wall. At this time, since the wall height of the adjacent region is relatively low in the opposing wall, water is easily guided downward beyond the boundary between the lower surface of the water guiding rib and the adjacent region of the opposing wall. As a result, it is possible to prevent water from entering from the boundary between the lower surface of the water guiding rib and the adjacent region of the opposing wall. That is, the opposing wall has a function of smoothly flowing down water that does not enter the housing side while flowing away from the original guide path of the water guide rib.

  As described above, according to the present invention, in the vehicle door lock device in which the protective member is attached to the housing, it is possible to enhance the effect of preventing flooding with respect to the opening formed in the protective member.

  Hereinafter, a vehicle door lock device according to an embodiment of the present invention (hereinafter also simply referred to as a “door lock device”) will be described with reference to a plurality of drawings. In the drawings, the front and rear of the vehicle or the door lock device housing are indicated by arrows X1 and X2, respectively, and the left and right sides of the vehicle or the door lock device housing are indicated by arrows Y1 and Y2, respectively. The upper and lower sides of the vehicle or the door lock device housing are indicated by arrows Z1 and Z2, respectively. These directions can be applied to the door lock device in a state before being assembled to the vehicle door and to the door lock device in a state after being assembled to the vehicle door.

  As shown in FIG. 1, the door lock device 100 according to the present embodiment is disposed in a region defined by a vehicle outer door outer panel and a vehicle inner door inner panel constituting the vehicle door DR. FIG. 1 shows a vehicle door on the right side of the rear seat as a typical example of the vehicle door DR.

  The housing 101 of the door lock device 100 is configured by joining a vehicle exterior component member 101a and a vehicle interior component member 101b made of a resin material to each other. The housing 101 includes a protrusion 102 extending from the housing surface. The convex portion 102 is typically composed of a first rib 102a erected along the edge of the vehicle exterior component 101a and a second rib 102b erected along the edge of the vehicle interior component 101b. It is formed by joining together by welding. This convex part 102 fulfill | performs the water stop function which blocks | prevents the flow of the water which tries to infiltrate into the vehicle inside from the vehicle outer side. The housing 101 has an accommodation space for accommodating a plurality of components including the latch mechanism 110 and the lock mechanism 120. That is, the housing 101 is configured as a housing that houses at least the latch mechanism 110 and the lock mechanism 120. In this housing 101, the accommodation space for the latch mechanism 110 is typically provided on the vehicle rear side so as to face the striker ST fixed to the vehicle body BD, and the lock mechanism is located on the vehicle front side from the accommodation space. A storage space for 120 is provided. The housing 101 corresponds to the “housing” of the present invention.

  A protective member (also referred to as a “protector”) 130 made of a resin material is attached to the lower portion of the housing 101. The protection member 130 is a member that is attached to the housing 101 to protect the housing 101 and has a separate structure from the housing 101. According to the protection member 130, the components of the door lock device 100 housed in the housing 101 are protected from water existing outside the housing 101. This protective member 130 corresponds to the “protective member” of the present invention.

  The latch mechanism 110 can hold the vehicle door DR in a closed state by engaging with the striker ST attached to the vehicle body BD. The lock mechanism 120 sets the latch mechanism 110 to an unlocked state where the engagement with the striker ST can be released, or a locked state where the engagement with the striker ST cannot be released. The latch mechanism 110 and the lock mechanism 120 correspond to the “latch mechanism” and the “lock mechanism” of the present invention, respectively. For further specific structures of the latch mechanism 110 and the lock mechanism 120, refer to, for example, the structure of a door lock device disclosed in Japanese Patent Laid-Open No. 2013-167145.

  As shown in FIG. 2, the lock mechanism 120 includes an inside open lever 121, an outside open lever (not shown), and an active lever 122. The inside open lever 121 is connected to an inside door handle 121a provided on the vehicle door DR via an inside open cable W1. For this reason, the inside open lever 121 rotates by operation of the inside door handle 121a. The outside open lever is connected to an outside door handle (not shown) provided on the vehicle door DR. For this reason, an outside open lever rotates by operation of an outside door handle. The active lever 122 is connected to a door lock knob 122a provided on the vehicle door DR via a locking cable W2. Therefore, the active lever 122 rotates by operating the door lock knob 122a and the key cylinder (not shown).

  The inside open cable W1 and the locking cable W2 are both control cables in which an inner cable is movably inserted inside a hollow outer cable. In the inside open cable W1, the inner cable exposed from the end of the outer cable is locked to the inside open lever 121. Similarly, in the locking cable W <b> 2, the inner cable exposed from the end of the outer cable is locked to the active lever 122. Both the inside open cable W1 and the locking cable W2 are installed and held on the standing wall 106 provided on the housing 101 and the two standing walls 136 and 137 provided on the protection member 130. It is assembled to the housing 101. The inside open cable W1 is led out of the protection member 130 through an opening provided in the protection member 130 (cable lead-out opening 130a in FIG. 1). Similarly, the locking cable W2 is led out of the protective member 130 through an opening provided in the protective member 130 (cable lead-out opening 130b in FIG. 1).

  As shown in FIGS. 2 and 3, the protection member 130 includes a first cover part 131 and a second cover part 141. The first cover part 131 includes the standing walls 136 and 137. The first cover 131 is attached to the housing 101 before the cables W1 and W2 are installed on the standing walls 136 and 137. The first cover part 131 is connected to the second cover part 141 via two hinge parts 150 and 150. In this case, the hinge portions 150 and 150 are both thin portions provided between the first cover portion 131 and the second cover portion 141 made of a resin material, and are hinged by utilizing the flexibility of the thin portion. It is configured as a so-called “integral hinge” that causes a function. Accordingly, the operator can rotate the second cover portion 141 around the hinge portions 150 and 150 (hinge line 150a) with respect to the first cover portion 131 while holding the second cover portion 141. it can.

  In the protection member 130, the first cover part 131, the second cover part 141, and the hinge parts 150 and 150 are integrally formed of a resin material. Thereby, the structure of the protection member 130 can be simplified. Further, in this protective member 130, a protruding wall 136a protruding from the standing wall 136 of the first cover part 131 and two protruding walls 148a and 148a protruding from the standing wall 148 of the second cover part 141, respectively, The cable lead-out openings 130a and 130b are surrounded. In this case, the cooperation of the projecting wall 136a and the projecting walls 148a and 148a can prevent the flow of water from flowing into the cable outlet openings 130a and 130b.

  In one aspect of the protection member 130, the second cover part 141 is set at a predetermined deployment position (position shown in FIGS. 2 and 3) that extends horizontally along the extending surface of the first cover part 131. The When the second cover part 141 is in the unfolded position, a state is formed in which the second cover part 141 is opened by approximately 180 ° with respect to the first cover part 131. Generally, in the initial state where the hinge portions 150 and 150 are not bent once after the resin molding of the protection member 130, the second cover portion 141 is in the unfolded position.

  In another aspect of the protection member 130, the second cover portion 141 is set in a closed position (position shown in FIG. 1) that completely covers the standing walls 136 and 137 of the first cover portion 131 from the vehicle interior side. In this closed position, the cover inner surface of the first cover portion 131 and the cover inner surface of the second cover portion 141 are in opposition to each other. Of course, the second cover portion 141 can be set at an arbitrary position between the deployed position and the closed position. For this reason, the 2nd cover part 141 can be set to an expansion | deployment position, before the 1st cover part 131 is attached to the housing 101 and the cables W1 and W2 are constructed on the standing walls 136 and 137. Thereafter, after the cables W1, W2 are installed on the standing walls 136, 137, the second cover part 141 can be rotated from the deployed position to the closed position around the hinge parts 150, 150.

  The standing wall 136 is configured as an outer wall exposed on the outer surface of the protection member 130. Accordingly, the standing wall 136 prevents the flow of water from entering the protective member 130 from the front of the vehicle. On the other hand, the standing wall 137 is configured as an inner wall provided inside the protection member 130. As a result, the standing wall 137 prevents the water from entering the protective member 130 from the front of the vehicle and flowing toward the housing 101. That is, the flow of water that tends to flow toward the housing 101 is blocked by the two standing walls 136 and 137 in two stages.

  As shown in FIG. 4, the standing wall 136 is configured as a plate-like extending piece that extends toward the mounting surface of the housing 101 (the mounting surface 101 c of the vehicle interior component member 101 b in FIG. 4). The extending tip 136b of the standing wall 136 has an inclined surface 136c that is inclined so that the plate thickness gradually decreases toward the tip, and the inclined surface 136c is shaped along the attachment surface 101c. In this case, the inclined surface 136c of the standing wall 136 is configured as a contact surface that comes into contact with the mounting surface 101c. For example, when the mounting surface 101c of the housing 101 is a flat surface, the inclined surface 136c of the standing wall 136 can be a flat surface that follows the flat surface, and the mounting surface 101c of the housing 101 is a curved surface. In some cases, the inclined surface 136c of the standing wall 136 can be a curved surface following the curved surface. According to this surface contact structure, a high water sealing effect can be obtained between the standing wall 136 provided on the first cover portion 131 of the protection member 130 and the mounting surface of the housing 101. In particular, by providing an inclined surface 136c on the extended tip 136b of the standing wall 136, the contact area between the extended tip 136b and the mounting surface 101c is increased even if the plate thickness of the standing wall 136 is constant. This is advantageous for enhancing the water sealing effect.

  Further, the standing wall 136 extends along a second reference line L2 that forms a predetermined angle θ with respect to the first reference line L1 in a state where the protection member 130 is attached to the housing 101. The angle is set. In this case, the first reference line L1 is typically defined as a line extending in the vertical direction in a state where the vehicle equipped with the door lock device is installed on a flat ground. The angle θ is a value (typically within a range of 15 to 20 degrees) such that the second reference line L2 does not reach the position where the second reference line L2 extends in the horizontal direction even when the mounted vehicle is tilted on a slope. Value). Thereby, the standing wall 136 can be applied to the housing 101 at an acute angle, and water can flow down along the surface of the standing wall 136 regardless of the traveling state of the mounted vehicle. As a result, it is possible to prevent a water pool from being formed at a portion where the inclined surface 136c of the standing wall 136 is in contact with the mounting surface 101c and water from entering from the portion.

  In addition, about the extension front-end | tip part 136b of the standing wall 136, it can replace with the structure shown in FIG. 4, and can also employ | adopt the structure shown in FIG. An inclined surface 136c provided at the extended tip portion 136b of the standing wall 136 in FIG. 5 is a contact surface that comes into contact with the mounting surface 101c when pressed against the mounting surface 101c of the housing 101 and deformed. It is configured as. For this purpose, in the standing wall 136, it is preferable to make the extending tip 136b thinner than other parts so that the inclined surface 136c is easily bent and deformed. In this case as well, a high water sealing effect can be obtained between the standing wall 136 and the mounting surface of the housing 101 with a simple structure as in the configuration shown in FIG. In particular, since the pressing force against the mounting surface 101c of the housing 101 is increased by the bending and deformation of the inclined surface 136c of the protection member 130, it is advantageous for enhancing the water sealing effect. In addition, the contact area between the extended tip portion 136b of the standing wall 136 and the mounting surface 101c can be increased.

  The first cover part 131 of the protection member 130 is attached to the housing 101. For this purpose, as shown in particular in FIG. 6, the first cover portion 131 includes a locking means (a locking claw 132, a locking recess) capable of locking the first cover portion 131 to the housing 101. (Locking slits) 138, 139) are provided. The locking claw 132 has a claw shape that can be engaged with the extended region 103 that extends toward the vehicle lower side (lower housing) Z <b> 2 of the convex portion 102 of the housing 101. The locking concave portion 138 is provided on the standing wall 136 of the first cover portion 131 and can be engaged with an extension region 104 that extends toward the vehicle front (front of the housing) X <b> 1 of the convex portion 102 of the housing 101. It is comprised as a recessed part. The locking recess 139 is provided on the standing wall 137 of the first cover 131 and is configured as a recess that can be engaged with the extension region 104 of the protrusion 102 of the housing 101.

  Therefore, according to the locking means of the first cover part 131 of the protection member 130, in the state where the first cover part 131 is attached to the housing 101, as shown in FIG. 103 is engaged with the locking claw 132, and the locking recesses 138 and 139 are engaged with the extended region 104 of the housing 101. In FIG. 6, for the sake of convenience, the protection member 130 with the second cover portion 141 removed is shown. The first cover part 131 is configured to engage with the second cover part 141 when the second cover part 141 is set to the closed position. For this purpose, the first cover portion 131 is provided with an engagement protrusion 135 that can be engaged with the opening portion of the second cover portion 141 (opening portion 144 in FIG. 3). The engagement protrusion 135 has a structure that is fitted into the opening 144 using the elasticity of the material, that is, a so-called “snap-fit structure”.

  On the other hand, as shown in FIG. 7, the second cover portion 141 has locking means (locking claw 142, locking recess (locking slit)) that can lock the second cover portion 141 to the housing 101. 149). In FIG. 7, for the sake of convenience, the protection member 130 with the first cover 131 removed is shown. The locking claw 142 has a claw shape that can be engaged with a region (extension region 105 in FIG. 2) of the convex portion 102 of the housing 101 that extends toward the vehicle rear (housing rear) X2. The locking recess 149 is provided on the standing wall 148 of the second cover portion 141 and engages with the extension region 104 of the convex portion 102 of the housing 101 in the same manner as the locking recesses 138 and 139 of the first cover portion 131. It is configured as a possible recess.

  Therefore, according to the locking means of the second cover portion 141 of the protection member 130, in the state where the second cover portion 141 is set to the closed position, as shown in FIG. The locking claw 142 is engaged with the extended region 105), and the locking recess 149 is engaged with the extended region 104 of the housing 101. Further, as described above, the engagement protrusion 135 of the first cover portion 131 is fitted into the opening 144 of the second cover portion 141.

  Although details will be described later, an interference wall 145, an opposing wall 146, and a water guiding slit 147 are provided on the cover surface of the second cover portion 141 as shown in FIG. The interference wall 145 is formed by a convex portion protruding toward the vehicle left side (housing left side) Y1 extending continuously along the vehicle vertical direction (housing vertical direction) Z1, Z2. The facing wall 146 is formed by a convex portion projecting toward the vehicle left side (housing left side) Y1 extending continuously along the vehicle front-rear direction (housing front-rear direction) X1, X2. The water guide slit 147 is formed at a boundary portion between the interference wall 145 and the opposing wall 146.

  In the protection member 130 having the above-described configuration, in order to prevent the components housed in the housing 101 from freezing or rusting, a structure that prevents water from entering the opening formed in the protection member 130. Is required. In this regard, as shown in FIG. 8, the opening 144 of the second cover portion 141 is provided above the housing with respect to the cable lead-out openings 130 a and 130 b, and the water flowing down the housing surface of the housing 101. This is the site where we want to protect the water with priority. Therefore, the door lock device 100 according to the present embodiment includes a water guiding structure in which at least the opening 144 is a target for flood protection.

  This water guiding structure corresponds to the “water guiding structure” of the present invention, and fulfills the function of guiding water so as to avoid the opening 144 formed in the protective member 130. For this purpose, this water guiding structure includes two water guiding ribs 107 and 108 disposed on the housing surface of the housing 101 (side surface of the vehicle interior component member 101b) in the vertical direction of the housing, and a protective member. And an interference wall 145 provided on the 130 second cover portion 141.

  The water guiding rib 107 is erected in an elongated shape along the housing front-rear direction X1, X2 on the side surface of the vehicle interior component 101b above the opening 144. The water guide rib 107 functions to guide water that has entered the vehicle door to a predetermined water guide region 107a above the opening 144 along the upper surface of the rib. The water guide rib 107 is a rib provided above the housing relative to the water guide rib 108 and corresponds to the “water guide rib” and the “upper rib” of the present invention.

  The water guide rib 108 is erected in a long shape below the water guide rib 107 on the side surface of the vehicle interior component member 101b along the housing front-rear directions X1 and X2. The water guide rib 108 functions to guide water that has entered the vehicle door to a predetermined water guide region 108a below the opening 144 along the top surface of the rib. The water guide rib 108 is a rib provided below the housing from the water guide rib 107 and corresponds to the “water guide rib” and the “lower rib” of the present invention.

  The interference wall 145 is interposed between the water guiding region 107a of the water guiding rib 107 and the opening 144, and between the water guiding region 108a of the water guiding rib 108 and the opening 144 in the housing vertical direction Z1 and Z2. Intervening along. Accordingly, the interference wall 145 functions to interfere with the flow of water from each of the water guiding regions 107a and 108a toward the opening 144. Therefore, the flow of water from each of the water guiding regions 107a and 108a toward the opening 144 can be blocked by the interference wall 145, so that water does not easily enter the opening 144. Further, the interference wall 145 extends in a long shape so as to face both the water guide rib 107 and the water guide rib 108 so that the water guided to the water guide region 107a is further guided to the merge region 107b. It is configured.

  In this case, the merging region 107b is located on the upper surface of the water guiding rib 108 below the housing from the opening 144, and is farther from the opening 144 than the water guiding region 107a in the housing front-rear direction X1 and X2. Therefore, the water guided to the merge area 107b by the water guide rib 107 is further guided by the interference wall 145 in the direction away from the opening 144, and merged with the water guided to the merge area 107b by the water guide rib 108. it can. As a result, it is possible to form a dedicated guide path that makes it difficult for water to flow toward the opening 144 over the range from the upper region to the lower region of the opening 144 of the protective member 130, thereby enhancing the effect of preventing flooding to the opening 144. be able to.

  According to the water guiding structure having the above configuration, a water guiding flow as shown in FIG. 9 can be formed. More specifically, water that has entered the vehicle door flows in the direction indicated by the arrow f1 according to gravity and then reaches the upper surface of the water guide rib 107. Alternatively, the water that has entered the vehicle door flows in the direction indicated by the arrow f2 according to gravity and then reaches the upper surface of the water guide rib 108.

  In the water guiding rib 107, water is guided to the water guiding region 107a by flowing in the direction indicated by the arrow f3 along the rib upper surface. In the water guiding region 107a, the flow of water toward the opening 144 interferes with the interference wall 145, whereby the flow direction of the water changes, and the direction indicated by the arrow f4 toward the merge region 107b along the interference wall 145. Be guided to. At this time, it is preferable that the interference wall 145 has a curved shape that guides the water guided to the water guiding region 107a in a direction further away from the opening 144. Thereby, the water induced | guided | derived to the water guidance area | region 107a can be kept away from the opening part 144 more. As a result, it is possible to further enhance the effect of preventing flooding with respect to the opening 144.

  The water guide rib 108 is fitted into the water guide slit 147. The water guide slit 147 has a slit width such that a gap is formed between the water guide rib 108. For this reason, the water guided in the direction indicated by the arrow f5 by the water guide rib 108 joins the water guided to the joining region 107b along the interference wall 145, and then the water guide rib 108 and the water guide slit 147 It guide | induces to the water guidance area | region 108a through the clearance gap between them. Thereafter, the water guided to the water guiding area 108a flows down to the drainage area 109 having a little influence on the water in the direction indicated by the arrow f6 according to gravity.

As shown in FIG. 11, the facing wall 146 of the second cover portion 141 is disposed to face the lower side of the water guiding rib 108 and extends in a long shape along the lower surface of the water guiding rib 108. Is preferred. The facing wall 146 corresponds to the “facing wall” of the present invention. The opposing wall 146 has a wall height in the standing height direction of the water guiding rib 108 that is lower than the standing height d of the water guiding rib 108 in the proximity region 146a close to the lower surface of the rib, and downward from the proximity region 146a. It is configured to gradually increase toward the separation region 146b that is spaced apart from each other, and to exceed the standing height d of the water guiding rib 108 in the separation region 146b. This configuration can be typically realized by gradually increasing the thickness of the opposing wall 146 from the proximity region 146a to the separation region 146b.

  As shown in FIG. 11, the facing wall 146 of the second cover portion 141 is disposed to face the lower side of the water guiding rib 108 and extends in a long shape along the lower surface of the water guiding rib 108. Is preferred. The facing wall 146 corresponds to the “facing wall” of the present invention. The opposing wall 146 has a wall height in the standing height direction of the water guiding rib 108 that is lower than the standing height d of the water guiding rib 108 in the proximity region 146a close to the lower surface of the rib, and downward from the proximity region 146a. It is configured to gradually decrease toward the separation region 146b that is spaced apart from each other, and to exceed the standing height d of the water guiding rib 108 in the separation region 146b. This configuration can be typically realized by gradually increasing the thickness of the opposing wall 146 from the proximity region 146a to the separation region 146b.

  According to this configuration, the water (see the arrow in FIG. 11) that has flowed down to the vehicle lower side (lower housing) Z <b> 2 beyond the water guiding rib 108 flows along the facing wall 146. At this time, since the wall height of the proximity region 146a is relatively low in the opposing wall 146, water is easily guided downward beyond the boundary between the rib lower surface of the water guiding rib 108 and the proximity region 146a of the opposing wall 146. . As a result, it is possible to prevent water from entering from the boundary between the lower surface of the water guiding rib 108 and the adjacent region 146a of the opposing wall 146. That is, the facing wall 146 has a function of smoothly flowing down water that does not enter the housing 101 side and flows out of the original guide path of the water guide rib 108. In addition, it is preferable that this opposing wall 146 is the structure contact | abutted to the rib lower surface of the water guidance rib 108 in the proximity | contact area | region 146a. In this case, it is possible to more reliably prevent water from entering from the boundary between the rib lower surface of the water guiding rib 108 and the adjacent region 146a of the opposing wall 146.

  When water intrusion from the boundary between the rib lower surface of the water guiding rib 108 and the adjacent region 146a of the opposing wall 146 does not occur or is difficult to occur, a region separated from the adjacent region 146a in the opposing wall 146 configured as described above It is also possible to adopt a structure in which the wall height is constant up to 146b, or a structure in which the opposing wall 146 itself configured as described above is omitted.

  As shown in FIG. 12, the protective member 130 having the above-described configuration is sandwiched in the housing 101 by sandwiching the housing 101 from both sides in the vehicle left-right direction (housing left-right direction) Y 1, Y 2. It is attached (see arrow in FIG. 12). In a state where the protective member 130 is attached to the housing 101, the first cover portion 131 is attached to the vehicle exterior component member 101 a of the housing 101, and the second cover portion 141 is attached to the vehicle interior component member 101 b of the housing 101. Is done. According to this sandwiching structure, the first cover portion 131 and the second cover portion 141 can be independently attached to the side surface of the housing 101, so that the attachment surface of each cover portion is the outer shape of the existing housing 101. It becomes easy to follow. As a result, it is possible to obtain a water sealing performance effective in preventing water from entering the housing 101 from the boundary portion between the side surface of the housing 101 and the adherend surface of the protection member 130.

  In this case, the protection member 130 slides the first cover portion 131 and the second cover portion 141 in the vehicle left-right direction Y1, Y2 according to the size of the housing 101 (hereinafter also referred to as “width dimension”). It has a structure (hereinafter also referred to as “slide structure”) that can be used. According to this slide structure, even when the width dimension of the housing 101 is changed due to the influence of the assembled state of the components accommodated in the housing 101, the attached state of the protective member 130 to the housing 101 is maintained. The shape of the protection member 130 can be made to follow the existing shape of the housing 101 as it is. As a result, when the width dimension of the housing 101 changes, the above-described water sealing performance does not occur, so that the phenomenon that the adherend surface of the protective member 130 is separated from the side surface of the housing 101 does not occur. Can be maintained. In this case, since a desired water sealing performance can be obtained without attaching a sealing member such as a non-woven fabric to the boundary portion between the side surface of the housing 101 and the adherend surface of the protection member 130, the door locking device can be obtained by omitting the sealing member. Simplification of the structure of 100 can be achieved. Further, since the protection member 130 changes only in the dimensions in the vehicle left-right direction Y1, Y2 depending on the slide structure, the tolerance of the door lock device 100 can be easily managed.

  As shown in FIG. 12, the protection member 130 having the above-described configuration is provided with a standing wall 136 and a first wall 136 that extend from the first cover portion 131 toward the second cover portion 141 when attached to the housing 101. The standing wall 148 extending from the two cover portions 141 toward the first cover portion 131 is in the thickness direction (plate thickness direction) of these standing walls 136 and 148 in the overlapping region 151 on the front side of the vehicle, that is, the front and rear of the vehicle With respect to the direction, it has a structure (hereinafter also referred to as “overlap structure”) that partially overlaps with each other. According to this overlap structure, it is possible to obtain an effect of preventing water from entering from the boundary between the protective member 130 and the housing 101 at the front side of the protective member 130.

  Further, as shown in FIGS. 13 to 15, the protective member 130 having the above-described configuration has a locking structure that is locked to the housing 101 using the convex portion 102.

  This locking structure will be specifically described. In the first cover portion 131 of the protection member 130, the locking recess 138 of the standing wall 136 is hooked on the projection 102 (extension region 104) (see FIG. 13). In addition, the locking recess 139 of the standing wall 137 is hooked on the protrusion 102 (extension region 104) (see FIG. 14), and is locked and held by the housing 101. In this case, the slit width dimensions of the locking recesses 138 and 139 are configured to substantially match the width dimension of the protrusion 102. Similarly, as shown in FIG. 15, the second cover portion 141 of the protection member 130 includes the housing 101 as a result of the locking concave portion 149 of the standing wall 148 being hooked on the convex portion 102 (extension region 104). It is locked and held. In this case, the slit width dimension of the locking recess 149 is configured to substantially match the width dimension of the protrusion 102.

  According to this locking structure, since the first cover portion 131 and the second cover portion 141 of the protective member 130 are locked to the housing 101 via the convex portions 102, the protective member 130 can be easily attached to the housing 101. Workability for installation can be improved. In particular, the first cover portion 131 has two locking recesses 138 and 139 that are hooked on the convex portion 102, so that the locking force is increased. In addition, since the convex portion 102 of the housing 101 and the standing walls 136, 137, and 148 of the protection member 130 are also used as a locking means for locking the protection member 130 to the housing 101, a dedicated locking means is used. There is no need to provide it, and the increase in the outer shape of the door lock device 100 can be suppressed.

  In the above-described locking structure, the first cover 131 is positioned on the vehicle right side (housing right side) Y2 as indicated by the arrows in FIGS. 13 and 14 in a state where the protective member 130 is locked to the housing 101. The second cover portion 141 is preferably urged toward the vehicle left side (housing left side) Y1 as indicated by an arrow in FIG. That is, in a state where the protective member 130 is attached to the housing 101, that is, in a state where both the first cover portion 131 and the second cover portion 141 are hooked on the convex portion 102, the first cover portion 131 and the second cover portion 141 are Each is biased so as to be separated from each other in the vehicle left-right direction Y1, Y2.

  In this case, in the first cover portion 131, one of the two slit surfaces 138a and 138b of the locking recess 138 is pressed against the second rib 102b, and the two slit surfaces 139a of the locking recess 139 are pressed. , 139b, one slit surface 139a is pressed against the second rib 102b. In the second cover portion 141, one slit surface 149b of the two slit surfaces 149a and 149b of the locking recess 149 is pressed against the first rib 102a. As a result, the first cover portion 131 and the second cover portion 141 of the protection member 130 are firmly locked to the convex portion 102 of the housing 101, respectively.

  The present invention is not limited to the above exemplary embodiment, and various applications and modifications are possible. For example, each of the following embodiments to which the above embodiment is applied can be implemented.

  In the water guiding structure of the door lock device 100 described above, the case where the opening 144 formed in the protection member 130 is subject to flood protection has been described, but the cable lead-out openings 130a and 130b are located above the opening 144. In the configuration in which the cable is disposed, these cable lead-out openings 130a and 130b can be the target of flood protection.

  In the water guiding structure of the door lock device 100 described above, the two water guiding ribs 107 and 108 arranged on the housing surface of the housing 101 so as to be separated from each other in the vertical direction of the housing are used. More than one water guide rib can also be used. When the water guide rib 108 is omitted from the two water guide ribs 107 and 108, it is preferable to assign an opposing wall having the same configuration as the opposing wall 146 to the water guide rib 107.

  In the water guiding structure of the door lock device 100 described above, the interference wall 145 extends in a long shape so as to face the two water guiding ribs 107 and 108, and the water guided to the water guiding region 107a is further removed. Although the description has been given of the case of a curved shape that guides in a direction away from the opening 144, in the present invention, the interference wall 145 has a function of interfering with the flow of water from the water guiding region 107a toward the opening 144. At least it is enough. Therefore, in the present invention, a configuration in which the interference wall 145 faces only the water guide rib 107 or a configuration in which the interference wall 145 extends linearly in the vehicle vertical direction can be employed.

  In the door lock device 100 described above, the protective member 130 in which the first cover part 131, the second cover part 141, and the hinge part 150 are integrally formed of a resin material has been described. However, these three components have separate structures. In addition, at least one of these three components may be made of a metal material.

  In the present invention, the essential structure of the door lock device 100 described above can be applied to each vehicle door of the vehicle. For example, the essential structure of the vehicle door lock device 100 can be applied to the left and right doors for the front seat of the vehicle, the left and right doors for the rear seat of the vehicle, and the back door at the rear of the vehicle.
