Detailed Description
Hereinafter, one embodiment will be described with reference to the drawings. In the following description, for convenience, the positive Z-axis direction is shown as the upper side in the drawing, and the negative Z-axis direction is shown as the lower side in the drawing.
(outline of the switching device 100)
Fig. 1 is an external perspective view of a switching device 100 according to an embodiment. Fig. 2 is a top view of one embodiment of the switching device 100. Fig. 3 is a front view of one embodiment of the switch device 100.
The switch device 100 shown in fig. 1 to 3 is a device that is incorporated in a trunk, a rear door, a side door, and the like of a vehicle as a switch for electrically unlocking the trunk, the rear door, and the like of the vehicle or electrically locking the side door, and the like of the vehicle, for example. As shown in fig. 1 to 3, the switchgear 100 has a substantially rectangular parallelepiped shape. That is, the switch device 100 has a substantially rectangular shape that is horizontally long with the X-axis direction being the long side direction and the Y-axis direction being the short side direction when viewed from above.
A cover member 130 is provided on an upper surface 110A (an example of an "operation surface") of the housing 110 of the switch device 100. The cover member 130 has an operating portion 132 projecting upward. When the operator presses the operation unit 132, the switch device 100 enters the following state: a switch 144 provided inside the housing 110 is switched to an on state, and two wires 146 drawn out from the bottom of the housing 110 are conducted to each other.
(construction and operation of the switching device 100)
Fig. 4 is an exploded perspective view of the switch device 100 according to one embodiment. Fig. 5 is a sectional view a-a of the switching device 100 (off state) shown in fig. 2. Fig. 6 is a sectional view a-a of the switching device 100 (on state) shown in fig. 2.
As shown in fig. 4 to 6, the switch device 100 includes a lid member 130, a case 110, a circuit portion 140, and a sealing member 120 in this order from the top.
The housing 110 is a container-shaped member that forms the outer shape (i.e., a substantially rectangular parallelepiped shape) of the switchgear 100. A lower opening 110C (not shown) is formed in a bottom portion of the housing 110. The case 110 is formed using a relatively hard material (for example, hard resin). An opening 110B is formed in the upper surface 110A of the housing 110, and the opening 110B has a substantially rectangular shape (a horizontally-elongated rectangular shape having a longitudinal direction in the X-axis direction) when viewed from above in plan.
A substantially columnar pressing member 112 is provided inside the opening 110B and at a position overlapping the switch 144 in a plan view, so as to be separated from the housing 110. The pressing member 112 is formed together with the housing 110 by primary molding in two-color molding. When the cap member 130 is formed by secondary molding in the two-color molding, the upper portion 112A of the pressing member 112 is fixed to the back side (inside the tube portion 132B) of the operation portion 132 of the cap member 130. When the pressing member 112 is pressed by the operation portion 132, the pressing member moves downward as the operation portion 132 sinks downward, and thereby presses the top of the movable portion 144A of the switch 144 via the pressing surface 112D serving as the bottom surface thereof.
The cover member 130 is provided on the upper surface 110A (an example of the "operation surface") of the housing 110. The cover member 130 is a substantially thin plate-shaped member formed using an elastic material (e.g., an elastic body). The cover member 130 covers substantially the entire area of the upper surface 110A of the housing 110, and is in close contact with the upper surface 110A of the housing 110 (the peripheral portion of the opening 110B), thereby closing the opening 110B formed in the upper surface 110A of the housing 110. This prevents the cover member 130 from being immersed in water from the opening 110B into the housing 110.
The cover member 130 is formed integrally with the upper surface 110A of the housing 110 by secondary molding in two-color molding, using a material (elastic material) different from that of the housing 110. The cover member 130 has an operating portion 132 projecting upward. The operation part 132 is provided at the center of the cover member 130. The operation unit 132 is a portion that is pressed by an operator. The cover member 130 has a flat plate-shaped outer peripheral portion 134 around the operation portion 132.
The circuit portion 140 is assembled inside the case 110. The circuit portion 140 includes a circuit board 142, a switch 144, and two wires 146.
The circuit board 142 is a relatively hard flat plate-like member. The circuit Board 142 is, for example, a PWB (printed wiring Board).
The switch 144 is mounted in the center of the upper surface 142A of the circuit board 142. The switch 144 is disposed below the pressing member 112. The switch 144 includes a movable portion 144A and a base portion 144B. When the switch 144 is pushed by the operation unit 132, the top of the movable portion 144A is pushed by the pushing surface 112D of the pushing member 112 provided on the back side of the operation unit 132. When the movable portion 144A is pressed by the pressing member 112, the switch 144 is switched to the on state.
One end sides of the two lead wires 146 are connected to the switch 144 by soldering or the like on the upper surface 142A of the circuit board 142. The other end of the two lead wires 146 penetrates the closing member 120 provided at the bottom of the case 110 and is led out of the case 110.
The closing member 120 closes the lower opening 110C by being fitted into the lower opening 110C of the housing 110. The closing member 120 has the same shape (i.e., a substantially rectangular shape) as the lower opening 110C of the case 110 in a plan view. The closing member 120 is formed using an elastic material (e.g., rubber, elastic adhesive, or the like) or a hard adhesive. This allows the closing member 120 to be in close contact with the inner wall surface of the housing 110, thereby preventing water from entering the housing 110 through the lower opening 110C.
When the operator does not press the operation portion 132 as shown in fig. 5, the switch device 100 is in an initial state in which the operation portion 132 is not depressed downward. At this time, the switch 144 provided inside the housing 110 is turned off. Therefore, the two wires 146 are in a state of non-conduction with each other.
On the other hand, when the operator presses operation portion 132 as shown in fig. 6, operation portion 132 and outer peripheral portion 134, which is a peripheral portion of operation portion 132, elastically deform in switch device 100, and operation portion 132 thereby sinks downward. Thereby, the pressing member 112 fixed to the rear side of the operation portion 132 moves downward, and presses the top of the movable portion 144A of the switch 144 provided in the housing 110. Thereby, the switch 144 is switched to the on state. As a result, the two wires 146 are in a conductive state.
In the switch device 100, when the pressing operation of the operation portion 132 by the operator is released, the operation portion 132 is automatically returned to the initial state by the elastic force of the operation portion 132, the outer peripheral portion 134, and the switch 144. Along with this, the switch 144 automatically returns to the off state.
(Structure of case 110 and lid 130)
Fig. 7 and 8 are external perspective views of the case 110 and the cover member 130 included in the switch device 100 according to the embodiment. Fig. 7 shows a state in which the case 110 and the cover member 130 are not coupled to each other. Fig. 8 shows a state in which the case 110 and the cover member 130 are coupled to each other.
As shown in fig. 8, the cover member 130 is formed on the upper surface 110A of the housing 110 by secondary molding. The cover member 130 covers substantially the entire area of the upper surface 110A of the housing 110, and is in close contact with the upper surface 110A of the housing 110 (the peripheral portion of the opening 110B), thereby closing the opening 110B formed in the upper surface 110A of the housing 110. This prevents the cover member 130 from being immersed in water from the opening 110B into the housing 110.
As shown in fig. 7, a substantially columnar pressing member 112 is provided inside and at the center of the opening 110B of the housing 110 so as to be separated from the housing 110. The pressing member 112 is formed together with the housing 110 by primary molding in two-color molding. As shown in fig. 8, when the member 130 is formed on the upper surface 110A of the housing 110 by the secondary molding, the upper portion 112A of the pressing member 112 is fixed in the cylindrical portion 132B on the back side of the operation portion 132 of the cover member 130.
As shown in fig. 7, the operation portion 132 of the cover member 130 has a hollow shape with a back side (Z-axis negative side) opened. A cylindrical tube portion 132B is provided integrally with an outer wall portion 132A of the operation portion 132 of the cover member 130 at the center inside the space of the operation portion 132. The cylindrical portion 132B is formed by secondary molding so as to cover the upper portion 112A of the pressing member 112. Thus, as shown in fig. 8, the upper portion 112A of the pressing member 112 is fixed in the cylindrical portion 132B in a state of being fitted into the cylindrical portion 132B from below the cylindrical portion 132B.
In the space of the operation portion 132, 4 ribs 132C are provided at 90 ° intervals in an annular portion around the cylindrical portion 132B as an example of "ribs". Each rib 132C connects the tube portion 132B and the outer wall portion 132A. Each rib 132C is formed integrally with the outer wall portion 132A and the tube portion 132B by secondary molding. For example, when the operation portion 132 is pressed from an obliquely upward direction, each rib 132C suppresses the inclination of the tube portion 132B and the pressing member 112 in the space of the operation portion 132. Thus, each rib 132C can realize a direct and reliable pressing operation of the switch 144 by the operation portion 132.
As shown in fig. 7, a plurality of vertical wall portions 112C (an example of "convex portions") protruding outward in the radial direction are formed on the outer peripheral surface of the lower portion 112B of the pressing member 112. Specifically, in the example shown in fig. 7, four vertical wall portions 112Ca are formed at 90 ° intervals on the outer peripheral surface of the lower portion 112B of the pressing member 112, and a vertical wall portion 112Cb shorter than the vertical wall portion 112Ca is formed between two adjacent vertical wall portions 112 Ca. Thus, in the switch device 100 of the present embodiment, the surface area of the outer peripheral surface of the lower portion 112B of the pressing member 112 is enlarged. Therefore, in the switch device 100 of the present embodiment, when the movable mold holding the housing 110 and the pressing member 112 is pulled away from the fixed mold after the primary molding, the pressing member 112 can be prevented from being lifted from the movable mold or the pressing member 112 can be prevented from being detached from the movable mold. Further, the switch device 100 of the present embodiment can reduce the volume of the lower portion 112B as compared with the case where the lower portion 112B is simply formed in a cylindrical shape, and thus can reduce the amount of material used when forming the pressing member 112.
The upper portion 112A of the pressing member 112 has a tapered shape that tapers upward, and the outer peripheral surface thereof is smooth. Thus, in the switch device 100 of the present embodiment, when the movable-side mold holding the housing 110 and the pressing member 112 is pulled away from the fixed-side mold after the primary molding, the pressing member 112 can be easily removed from the fixed-side mold. Therefore, the switch device 100 of the present embodiment can prevent the pressing member 112 from being lifted from the movable-side mold or the pressing member 112 from falling off from the movable-side mold.
As shown in fig. 4 to 6, the pressing member 112 has a gate mark 112E formed in primary molding on the upper surface thereof, that is, the pressing surface 112D does not have a gate mark, so that the pressing surface 112D can be made smooth.
Fig. 9 is a B-B sectional view of the switching device 100 shown in fig. 3. As shown in fig. 9, the bottom surface (portion other than the plurality of vertical wall portions 112C) of the pressing member 112 becomes a pressing surface 112D. The area of the pressing surface 112D is larger than the area of the top of the movable portion 144A of the switch 144. Thus, in the switch device 100 according to the present embodiment, when an excessive operation load is applied to the pressing member 112, the pressing surface 112D abuts against the upper surface of the base portion 144B of the switch 144, and the operation load can be received by the upper surface of the base portion 144B of the switch 144. In the switch device 100 of the present embodiment, even when the pressing member 112 is displaced in the horizontal direction, the top portion of the movable portion 144A of the switch 144 can be reliably pressed by the pressing surface 112D.
(method of manufacturing casing 110)
Fig. 10 is a flowchart showing the procedure of the method for manufacturing the housing 110 according to the embodiment.
First, the housing 110 and the pressing member 112 are simultaneously formed by primary molding in two-color molding (step S11: primary molding step). Specifically, the movable mold is overlapped on the lower side of the primary fixed mold. Then, a liquid and thermoplastic hard resin material is injected into the space of the movable mold from a plurality of gates provided on the bottom surface of the primary fixed mold. A space having a shape corresponding to the housing 110 and the pressing member 112 is formed in the movable mold. Thus, the housing 110 and the pressing member 112 are formed in the movable mold.
Next, in the secondary molding in the two-color molding, the cap member 130 is formed by using an elastic material for the upper surface 110A of the case 110, and the pressing member 112 is fixed to the back side of the cap member 130 (step S12: secondary molding step), specifically, the movable-side mold holding the case 110 and the pressing member 112 is separated from the primary fixed-side mold and is overlapped with the lower side of the secondary fixed-side mold. Then, a liquid and thermoplastic elastic material is injected into the space of the secondary fixed-side mold. A space having a shape corresponding to the lid member 130 is formed in the secondary fixed-side mold. Thus, the cap member 130 is formed in close contact with the upper surface 110A of the housing 110, and the pressing member 112 is fixed to the back side of the operation portion 132 of the cap member 130.
As described above, the switching device 100 according to one embodiment includes: a housing 110 formed by primary molding in two-color molding; a switch 144 disposed inside the housing 110; a cover member 130 formed by secondary molding in two-color molding and using an elastic material, covering the upper surface 110A of the housing 110; and a pressing member 112 formed in the opening 110B of the upper surface 110A by primary molding, simultaneously with the housing 110 and separately from the housing 110, and fixed to the back side of the operation portion 132 of the cover member 130 by secondary molding, and pressing the top of the switch 144 when the operation portion 132 is pressed.
Thus, in the switch device 100 according to the embodiment, the pressing member 112 formed of a hard material is provided between the operation portion 132 of the cover member 130 and the top portion of the switch 144, whereby a direct operation feeling can be obtained.
In addition, since the pressing member 112 is formed simultaneously with the housing 110 by one-time molding in the switch device 100 according to the embodiment, the pressing member 112 can be easily disposed at a correct position in the opening 110B of the housing 110.
Further, in the switch device 100 according to the embodiment, the pressing member 112 is fixed to the back side of the operation portion 132 by one-time molding, and therefore the pressing member 112 can be fixed to the back side of the operation portion 132 in a state of being arranged at an accurate position in the opening portion 110B.
In the switch device 100 according to the embodiment, the pressing member 112 has a plurality of vertical wall portions 112C on the outer peripheral surface of the lower portion 112B (the end portion on the switch 144 side).
Accordingly, in the switch device 100 according to the embodiment, the surface area of the outer peripheral surface of the lower portion 112B is enlarged, and when the movable-side mold holding the housing 110 and the pressing member 112 is pulled away from the fixed-side mold after primary molding, the pressing member 112 can be prevented from being lifted from the movable-side mold or the pressing member 112 can be prevented from falling off from the movable-side mold.
In the switch device 100 according to the embodiment, the upper portion 112A (end portion on the lid member 130 side) of the pressing member 112 has a tapered shape.
Accordingly, in the switch device 100 according to the embodiment, when the movable-side mold holding the housing 110 and the pressing member 112 is pulled away from the fixed-side mold after the primary molding, the pressing member 112 can be easily removed from the fixed-side mold. Therefore, the switch device 100 according to the embodiment can prevent the pressing member 112 from being lifted from the movable-side mold or the pressing member 112 from falling off from the movable-side mold.
In the switch device 100 according to the embodiment, the pressing member 112 has a pressing surface 112D for pressing the top of the switch 144, and the pressing surface 112D has an area larger than the top of the switch 144.
Thus, in the switch device 100 according to the embodiment, when an excessive operation load is applied to the pressing member 112, the pressing surface 112D abuts against the upper surface of the base portion 144B of the switch 144, and the operation load can be received by the upper surface of the base portion 144B of the switch 144. In the switch device 100 according to the embodiment, even when the pressing member 112 is displaced in the horizontal direction, the top portion of the movable portion 144A of the switch 144 can be reliably pressed by the pressing surface 112D.
(modification example)
Next, a modification of the switchgear 100 according to the embodiment will be described with reference to fig. 11 to 13. Fig. 11 is an external perspective view of a switch device 200 (with a knob 250 removed) according to a modification. Fig. 12 is an external perspective view of a switch device 200 (in a state where a knob 250 is attached) according to a modification. Fig. 13 is a sectional view of a switchgear 200 according to a modification.
The switch device 200 shown in fig. 11 to 13 is different from the switch device 100 in that a case 210, a lid member 230, and a pressing member 212 are provided instead of the case 110, the lid member 130, and the pressing member 112, and a knob 250 is further provided.
The housing 210 is different from the housing 110 in that it further includes a pair of brackets 214. The pair of brackets 214 are provided to protrude outward from both side surfaces in the longitudinal direction (X-axis direction) of the housing 210. The pair of brackets 214 are formed with through holes 214A that penetrate the brackets 214 in the vertical direction.
The cover member 230 is provided on an upper surface 210A (an example of an "operation surface") of the housing 210. The cover member 230 is a substantially thin plate-shaped member formed using an elastic material (e.g., an elastomer). The cover member 230 covers substantially the entire upper surface 210A of the housing 210, thereby closing an opening 210B (see fig. 13) formed in the upper surface 210A of the housing 210. This prevents the cover member 230 from being immersed in water from the opening 210B into the housing 210. The cover member 230 is formed integrally with the upper surface 210A of the housing 210 by secondary molding in two-color molding, using a material different from that of the housing 210. The cover member 230 has a support portion 232 projecting upward. The support portion 232 is provided at the center of the cover member 230. The cover member 230 has a flat plate-shaped outer peripheral portion 234 around the support portion 232. The pressing member 212 to be pressed by the operator penetrates the support portion 232. Thereby, the supporting portion 232 supports the middle portion of the pressing member 212. That is, the cap member 230 is different from the cap member 130 in that the pressing member 212 penetrates the supporting portion 232.
The pressing member 212 is different from the pressing member 112 in that it penetrates the cover member 230. Specifically, the pressing member 212 is provided inside the opening 210B of the housing 210 so as to be separated from the housing 210, and is located at a position overlapping the switch 144 in a plan view. The pressing member 212 is formed together with the housing 210 by primary molding in two-color molding. When the cover member 230 is formed by secondary molding in two-color molding, the outer peripheral surface of the intermediate portion 212B of the pressing member 212 is fixed to the inner peripheral surface of the through hole 232A formed in the supporting portion 232 in a state of penetrating the supporting portion 232 of the cover member 230. Thereby, pressing member 212 is in a state in which upper portion 212A protrudes upward from support portion 232, intermediate portion 212B is held in through hole 232A of support portion 232, and lower portion 212C protrudes downward from support portion 232. The inner peripheral surface of the through hole 232A formed in the support portion 232 by two-color molding is brought into close contact with the outer peripheral surface of the intermediate portion 212B of the pressing member 212 by two-color molding. Therefore, the switchgear 200 of the present modification avoids the penetration of water into the case 210 from the through-hole 232A. Further, the pressing member 212 has a plurality of vertical wall portions (for example, four vertical wall portions arranged at 90 ° intervals) protruding outward in the radial direction formed on the outer peripheral surface of the upper portion 212A, and the volume of the upper portion 212A can be reduced as compared with the case where the upper portion 212A is formed in a simple cylindrical shape, thereby reducing the amount of material used when forming the pressing member 212.
The knob 250 is a flat plate-like member having a substantially rectangular shape in plan view. The knob 250 is formed using a relatively hard material (e.g., hard resin). A pair of hooks 252 are provided to hang downward at both ends (i.e., a pair of short side portions) in the longitudinal direction (X-axis direction) of the knob 250. The knob 250 is attached to be movable in the up-down direction with respect to the housing 210 so as to cover the upper surface 201A of the housing 210 by inserting a pair of hooks 252 into a pair of brackets 214 of the housing 210, respectively, from above. As shown in fig. 13, a holding hole 254 is formed in the center of the bottom surface of the knob 250. The knob 250 holds the upper portion 212A of the pressing member 212 by fitting the upper portion 212A of the pressing member 212 into the holding hole 254.
In the switch device 200 of the present modification, when the operator presses the knob 250, the pressing member 212, which is held by the knob 250 in the upper portion 212A, moves downward together with the knob 250 along with the elastic deformation of the support portion 232 and the outer peripheral portion 234 in the cover member 230. Thereby, the pressing member 212 presses the top of the movable portion 144A of the switch 144 provided in the housing 210 by the pressing surface 212D as the bottom surface thereof. Thereby, the switch 144 is switched to the on state. As a result, the two wires 146 are in a conductive state.
In the switch device 200 of the present modification, the knob 250 and the pressing member 212 are both formed using hard materials, and no elastic member is present between the knob 250 and the pressing member 212. Therefore, the switch device 200 of the present modification can press the switch 144 by the pressing member 212 with almost no reduction in the operation load applied to the knob 250. Therefore, according to the switch device 200 of the present modification, a more direct operation feeling can be obtained.
In the switch device 200 of the present modification, the knob 250 and the pair of hooks 252 may not be provided. That is, the operator may directly press the upper portion 212A of the pressing member 212. In this case, the following structure may be adopted: another knob made of a hard material or an elastic material is fixedly provided on the upper portion 212A of the pressing member 212.
While one embodiment of the present invention has been described in detail, the present invention is not limited to the embodiment, and various modifications and changes can be made within the scope of the present invention described in the claims.
The international application claims that the entire contents of the application is incorporated into the international application based on the priority of japanese patent application No. 2019-183197 applied on 3/10/2019.
