[0012] It should be noted that the above expressions are used for the sake of convenience of explanation and do not limit the insertion direction of the slide cover 2 (the installation posture of the assembly 100).
[0013] First Embodiment An assembly according to one embodiment will be described below with reference to the drawings. The cover material in this disclosure is a slide cover 2.
[0014] (Assembly configuration) The assembly 100 has a live part housed inside covered by a slide cover 2. The assembly 100 is used to prevent the live part from being accidentally exposed. 1 to 3, the assembly 100 of this embodiment includes a cover main body 1 and a slide cover 2. For example, the assembly 100 may be mounted on a mobility unit such as an electric vehicle.
[0015] (Cover body configuration) The cover body 1 houses live parts. 4 to 7, the cover body 1 includes a first wall portion 11, a second wall portion 12, a third wall portion 13, a fourth wall portion 14, a first rail portion 15, a second rail portion 16, at least one lower protrusion portion 17, at least one upper protrusion portion 18, and a restricting portion 19. For example, in this embodiment, the cover body 1 includes one lower protrusion portion 17 and two upper protrusion portions 18. The number of lower protrusions 17 and upper protrusions 18 is not limited.
[0016] The cover body 1 has an opening EX. The opening EX exposes a live part. For example, in this embodiment, the cover body 1 has the opening EX formed by a first wall portion 11, a second wall portion 12, a third wall portion 13, and a fourth wall portion 14. The cover body 1 also has a guide surface 15gs. The slide cover 2 is capable of sliding along the guide surface 15gs while facing the cover body 1.
[0017] (Configuration of each wall section) The first wall portion 11 has an outer wall surface 11es facing the -X direction and an inner wall surface 11is facing the +X direction. The second wall portion 12 has an outer wall surface 12es facing the +X direction and an inner wall surface 12is facing the -X direction. The third wall portion 13 has an outer wall surface 13es facing the -Y direction and an inner wall surface 13is facing the +Y direction. The fourth wall portion 14 has an outer wall surface 14es facing the +Y direction and an inner wall surface 13is facing the -Y direction. 6, the third wall portion 13 may have a hollow structure inside, and the fourth wall portion 14 may have a hollow structure inside.
[0018] (Configuration of the first rail section) The first rail portion 15 bridges the inner surfaces of both side walls in the Y direction. That is, the first rail portion 15 bridges the inner wall surface 13is and the inner wall surface 14is. The first rail portion 15 includes a flat portion 15k1 extending in the X direction and at least one standing portion 15k2 connected to the flat portion 15k1 and extending in the Z direction. When a load is applied in the -Z direction via the slide cover 2, the standing portion 15k2 suppresses deformation of the first rail portion 15.
[0019] The first rail portion 15 of the cover body 1 has a guide surface 15gs facing the first direction. In this embodiment, the surface of the flat portion 15k1 facing the +Z direction is the guide surface 15gs. The first rail portion 15 allows the sliding cover 2 to slide along the guide surface 15gs.
[0020] In this embodiment, for example, the first rail portion 15 and the first wall portion 11 are connected to each other.
[0021] The first rail portion 15 may also have a protruding portion 1511 that protrudes in the +Z direction. The protrusion 1511 is aligned with the second locking portion 151 in the +X direction.
[0022] The cover body 1 includes a second locking portion 151. The second locking portion 151 protrudes from the guide surface 15gs in the +Z direction.
[0023] (Second locking part) Prior to the first locking portion 23 described below, the second locking portion 151 will be described in detail. The second locking portion 151 has a second continuous surface 151A and a second locking surface 151B. The second continuous surface 151A and the second locking surface 151B are connected by an end ED. The second locking surface 151B is aligned in the +X direction continuously with the second continuous surface 151A and faces the +X direction. The second locking surface 151B is a surface along the +Z direction. The second continuous surface 151A includes a second inclined surface 151Aa that faces in a direction inclined toward the −X direction with respect to the +Z direction.
[0024] (Configuration of the second rail section) The second rail portion 16 is aligned with the first rail portion 15 in the +X direction. Similar to the first rail portion 15, the second rail portion 16 bridges the inner surfaces of both side walls in the Y direction. The second rail portion 16 includes a flat portion 16k1 extending in the X direction and at least one standing portion 16k2 connected to the flat portion 16k1 and extending in the Z direction. The standing portion 16k2 protrudes less from the wall surface as it extends in the -Z direction. When a load is applied in the -Z direction via the slide cover 2, the standing portion 16k2 suppresses deformation of the second rail portion 16.
[0025] The second rail portion 16 has a guide surface 16gs on the same plane as the guide surface 15gs. In this embodiment, the surface of the flat portion 16k1 facing the +Z direction is the guide surface 16gs.
[0026] In this embodiment, for example, the second rail portion 16 and the second wall portion 12 are connected to each other.
[0027] The second rail portion 16 may also have a protruding portion 161 that protrudes in the +Z direction. The protrusion 161 is aligned with the second locking portion 151 in the +X direction.
[0028] For example, in this embodiment, first rail portion 15 includes one standing portion 15k2, and second rail portion 16 includes two standing portions 16k2. Standing portion 16k2 is a shape obtained by extracting a portion of one standing portion 15k2. Comparing the cut areas in the Y direction, standing portion 16k2 is smaller than standing portion 15k2. The cover body 1 receives a force in the -Z direction via second lock portion 151. This force acts more strongly on first rail portion 15 than on second rail portion 16. If the cut areas in the X direction are the same for standing portion 15k2 and standing portion 16k2, standing portion 15k2 has a larger cut area in the Y direction than standing portion 16k2.
[0029] (Configuration of lower protrusion) The lower protrusions 17 are a pair of protrusions protruding from the inner surfaces of both side walls in the Y direction. For example, in this embodiment, the lower protrusions 17 include a protrusion protruding from the inner wall surface 13is and a protrusion protruding from the inner wall surface 14is. The lower protrusions 17 include a flat portion 17k1 extending in the X direction and at least one standing portion 17k2 connected to the flat portion 17k1 and extending in the Z direction. The amount of protrusion of the standing portion 17k2 from the wall surface decreases as it extends in the -Z direction. When a load is applied in the -Z direction via the slide cover 2, the standing portion 17k2 suppresses deformation of the lower protrusions 17.
[0030] The lower protrusion 17 has a guide surface 17gs on the same plane as the guide surface 15gs. In this embodiment, the surface of the flat portion 17k1 facing the +Z direction is the guide surface 17gs.
[0031] (Configuration of upper protrusion) The upper protrusion 18 is located in the +Z direction relative to the lower protrusion 17. The upper protrusions 18 are a pair of protrusions protruding from the inner surfaces of both side walls in the Y direction. That is, the upper protrusions 18 have a protrusion protruding from the inner wall surface 13is and a protrusion protruding from the inner wall surface 14is. The upper protrusions 18 include a flat portion 18k1 extending in the X direction. The upper protrusions 18 limit the movement of the sliding cover 2 in the +Z direction. For example, by introducing the ear portions 22k2 of the sliding cover 2 between the upper protrusions 18 and the lower protrusions 17, the movement of the sliding cover 2 in the +Z direction is limited.
[0032] The upper protrusion 18 may also have a protrusion 181 that protrudes in the −Z direction.
[0033] When viewed from the +Z direction, the first rail portion 15, the second rail portion 16, the at least one lower protrusion 17, and the at least one upper protrusion 18 are arranged alternately in the X direction. In other words, they do not overlap in the Z direction. When viewed from the +Z direction, the first rail portion 15 and the restriction portion 19 overlap in the Z direction.
[0034] (Configuration of the Regulatory Unit) The restricting portion 19 is aligned with the first rail portion 15 in the +Z direction. The restricting portion 19 is a pair of protruding portions protruding from the inner surfaces of both side walls in the Y direction. The restricting portion 19 includes a flat portion 19k1 extending in the X direction and at least one standing portion 19k2 connected to the flat portion 19k1 and extending in the Z direction. The amount of protrusion of the standing portion 19k2 from the wall surface decreases as it extends in the +Z direction. When a load is applied in the Z direction via the sliding cover 2, the movement of the sliding cover 2 is restricted by the standing portion 19k2.
[0035] For example, in this embodiment, the cover body 1 includes two upper protrusions 18, and the cover body 1 includes a restricting portion 19. Comparing the cut areas in the X direction, the cut area of the restricting portion 19 is smaller than the cut area of the upper protrusions 18. The cover body 1 receives a force in the +Z direction via the second locking portion 151. This force acts more strongly on the restricting portions 19 than on the upper protrusions 18. Therefore, to suppress deformation of the restricting portions 19, the restricting portions 19 include erected portions 19k2 that play a reinforcing role.
[0036] The restricting portion 19 may also have a protruding portion 191 that protrudes in the −Z direction. The protrusion 191 is aligned with the second locking portion 151 in the −X direction.
[0037] (Slide cover configuration) The slide cover 2 can slide in the +X direction along the guide surface 15gs while facing each other to close the opening EX. At this time, the slide cover 2 covers the live parts. As shown in FIGS. 8 to 11, the slide cover 2 includes a grip portion 21, an extension portion 22, a first locking portion 23, a third locking portion 24, and a reinforcing portion 25. As shown in FIGS.
[0038] (Configuration of gripping part) The grip portion 21 can come into contact with the outer wall surface 11es, allowing the insertion position of the slide cover 2 to be visually determined. For example, in this embodiment, the target insertion position (hereinafter also referred to as the "locking position") is set at a position where the third locking portion 24 climbs over the second locking portion 151 and is aligned in the X direction with the second locking surface 151B. Figure 12 shows an example of the locking position. At this time, the grip portion 21 is in contact with the outer wall surface 11es.
[0039] (Structure of extension part) The length of the extension portion 22 relative to the grip portion 21 is set appropriately so that the first locking portion 23 is aligned in the X direction with respect to the second locking surface 151B. For example, in this embodiment, the length of the extension portion 22 relative to the gripping portion 21 is set so that the first locking portion 23 and the third locking portion 24 are aligned in the X direction with respect to the second locking surface 151B. The extension portion 22 includes a flat portion 22k1 extending in the X direction, at least one or more ear portions 22k2 located in the -Z direction relative to the flat portion 22k1, and at least one or more standing portions 22k3 connected to the flat portion 22k1 and the ear portions 22k2 and extending in the Z direction. The ear portions 22k2 are capable of contacting the guide surface 15gs.
[0040] The sliding cover 2 has a sliding surface 22ss. The sliding surface 22ss faces the guide surface 15gs when the sliding cover 2 slides. The sliding cover 2 includes the ear portions 22k2 and the standing portions 22k3, so that a gap AA is provided between the guide surface 15gs and the sliding surface 22ss. A first locking portion 23 and a third locking portion 24 are provided to partially fill this gap AA.
[0041] (Configuration of the first locking section) The first locking portion 23 protrudes from the slide surface 22ss in the −Z direction. The first locking portion 23 may have a slit. The first locking portion 23 has a first engaging surface 23C and a first continuous surface 23D. The first locking surface 23C faces the −X direction and is a surface along the +Z direction. First continuous surface 23D is aligned continuously in the +X direction with first locking surface 23C. First continuous surface 23D includes first inclined surface 23Dd that faces a direction inclined in the +X direction with respect to the -Z direction.
[0042] (Configuration of the third locking part) The third locking portion 24 is aligned with the first locking portion 23 in the −X direction and protrudes from the slide surface 22ss in the −Z direction. The third locking portion 24 may have a slit. The third locking portion 24 has a third inclined surface 24E and a third continuous surface 24F. The third inclined surface 24E faces a direction inclined toward the −X direction with respect to the −Z direction. The third continuous surface 24F is aligned in the +X direction continuously with the third inclined surface 24E. The third continuous surface 24F includes a fourth inclined surface 24Ff that faces in a direction inclined toward the +X direction with respect to the -Z direction.
[0043] The first locking portion 23 can swing from the sliding surface 22ss toward the back surface 22bs of the sliding surface. The third locking portion 24 can swing from the sliding surface 22ss toward the back surface 22bs of the sliding surface. For example, the extension portion 22 has a first opening 22E1 and a second opening 22E2. The first opening 22E1 opens from the sliding surface 22ss to the back surface 22bs. The second opening 22E2 opens alongside the first opening 22E1 in the -X direction and also opens from the sliding surface 22ss to the back surface 22bs.
[0044] The first opening 22E1 is a U-shaped opening that sandwiches the first locking portion 23 in the direction along the +Y direction. The second opening 22E2 is a U-shaped opening that sandwiches the third locking portion 24 in the direction along the +Y direction.
[0045] (Structure of reinforcement part) The extension portion 22 of the sliding cover 2 mainly receives a force in the +Z direction from the second locking portion 151 via the first locking portion 23 and the third locking portion 24. Because the upper protrusion 18 restricts the movement of the sliding cover 2 in the +Z direction, bending may occur between the first locking portion 23 and the third locking portion 24. The reinforcing portion 25 serves to ensure the rigidity of the extension portion 22. The reinforcing portion 25 has two wall portions 25k1 and a bridge portion 25k2. The wall portion 25k1 stands upright from the back surface 22bs in the +Z direction. The bridge portion 25k2 bridges one wall portion 25k1 with the other wall portion 25k1.
[0046] (Operation of the first locking part and the third locking part) FIG. 12 shows the sliding cover 2 in the locked position. The procedure for bringing the slide cover into the locking position will be described in detail below.
[0047] 13, a part of the sliding cover 2 is inserted into the side surface (first wall portion 11) of the cover main body 1. When the sliding cover 2 is slid in the +X direction from this state, the ear portion 22k2 of the sliding cover 2 is introduced between the first rail portion 15 and the restricting portion 19. At this time, the movement of the sliding cover 2 in the Z direction is restricted.
[0048] 14 is a partial enlarged view of portion A in FIG. 13. In FIG. 14, the first locking portion 23 and the second locking portion 151 are in contact with each other. When the sliding cover 2 is slid in the +X direction from this state, the second inclined surface 151Aa of the second locking portion 151 presses the first locking portion 23 in the -X direction. When a predetermined force is applied, the first locking portion 23 swings due to a component of force in the +Z direction acting on the first inclined surface 23Dd, and moves over the second locking portion 151.
[0049] 15 is a partial enlarged view of portion A in FIG. 13. In FIG. 15, the first locking portion 23 climbs over the second locking portion 151, and then the third locking portion 24 and the second locking portion 151 come into contact. When the sliding cover 2 is slid in the +X direction from this state, the second inclined surface 151Aa presses the third locking portion 24 in the -X direction. When a predetermined force is applied, a component of force in the +Z direction acting on the fourth inclined surface 24Ff causes the third locking portion 24 to swing and climb over the second locking portion 151. In this way, the sliding cover 2 is locked at the locking position shown in FIG. 12. At this time, the live parts are covered by the sliding cover 2.
[0050] The following describes how to release the locked state of the slide cover 2. When the locked state is released, the live parts are exposed to the outside. 16 is a partial enlarged view of portion A in FIG. 13. In FIG. 16, the third locking portion 24 and the second locking portion 151 are in contact with each other. Specifically, the third inclined surface 24E of the third locking portion 24 is in contact with the end portion ED. When the sliding cover 2 is slid in the -X direction from this state, the end portion ED presses the third locking portion 24 in the +X direction. When a predetermined force is applied, the third locking portion 24 swings due to a component of force acting in the +Z direction on the third inclined surface 24E, and moves over the second locking portion 151.
[0051] 17 is a partial enlarged view of portion A in FIG. 13. As shown in FIG. 17, when the sliding cover 2 is slid in the -X direction, the third locking portion 24 climbs over the second locking portion 151, and then the first locking portion 23 and the second locking portion 151 come into contact. In this state, the second locking surface 151B and the first locking surface 23C come into surface contact, causing a component of force in the +X direction to be generated in the first locking portion 23. Because no component of force in the +Z direction is generated in the first locking portion 23, the first locking portion 23 does not swing. At this time, the first locking portion 23 cannot climb over the second locking portion 151. Therefore, the sliding cover 2 is less likely to come off the cover main body 1.
[0052] (Action and effect) In this embodiment, the assembly 100 includes a cover main body 1 having a guide surface 15gs facing a first direction (+Z direction) and an opening EX to which a live part is exposed, and a slide cover 2 that can slide along the guide surface 15gs toward a second direction (+X direction) while facing the guide surface 15gs to close the opening EX, the slide cover 2 has a slide surface 22ss that faces the guide surface 15gs during the slide movement, and includes a first locking portion 23 that protrudes from the slide surface 22ss in a third direction (-Z direction) opposite to the first direction, and the first locking portion 23 has a first locking surface 23C facing a fourth direction (-X direction) opposite to the second direction, The cover body 1 has a first continuous surface 23D that is continuously aligned in the second direction (+X direction) relative to the first direction (+Z direction), and the first continuous surface 23D includes a first inclined surface 23Dd that faces a direction that is inclined in the second direction (+X direction) relative to the third direction (-Z direction).The cover body 1 has a second locking portion 151 that protrudes from the guide surface 15gs toward the first direction (+Z) direction, and the second locking portion 151 has a second continuous surface 151A and a second engaging surface 151B that is continuously aligned in the second direction (+X direction) relative to the second continuous surface 151A and faces the second direction (+X direction).The second continuous surface 151A includes a second inclined surface 151Aa that faces a direction that is inclined in the fourth direction (-X direction) relative to the first direction (+Z direction). With this configuration, the second locking surface 151B and the first locking surface 23C are in surface contact with each other, making it difficult for a component force in the +Z direction to be generated in the first locking portion 23. At this time, the first locking portion 23 is difficult to swing. Therefore, the first locking portion 23 is difficult to climb over the second locking portion 151. As a result, the sliding cover 2 is difficult to fall off the cover main body 1.
[0053] In this embodiment, the first locking surface 23C is a surface extending along the first direction (+Z direction), and the second locking surface 151B is a surface extending along the first direction (+Z direction). With this configuration, the second locking surface 151B and the first locking surface 23C come into surface contact, causing a component force in the +X direction to be generated in the first locking portion 23. Since no component force in the +Z direction is generated in the first locking portion 23, the first locking portion 23 does not swing. At this time, the first locking portion 23 cannot climb over the second locking portion 151. Therefore, the sliding cover 2 is less likely to fall off the cover main body 1. This effect is expected in a vibration environment such as a vehicle.
[0054] In this embodiment, the sliding cover 2 further includes a third locking portion 24 that is aligned with the first locking portion 23 in the fourth direction (-X direction) and protrudes from the sliding surface 22ss in the third direction (-Z direction). The third locking portion 24 includes a third inclined surface 24E that faces in a direction inclined in the fourth direction (-X direction) with respect to the third direction (-Z direction), and a third continuous surface 24F that is aligned continuously with the third inclined surface 24E in the second direction (+X direction). The third continuous surface 24F includes a fourth inclined surface 24Ff that faces in a direction inclined in the second direction (+X direction) with respect to the third direction (-Z direction). When the sliding cover 2 is slid toward the second direction (+X direction), the first locking portion 23 and the second locking portion 151 come into contact, and then the third locking portion 24 and the second locking portion 151 come into contact. This configuration has the following advantages: When the sliding cover 2 slides in the -X direction to release the locked state of the sliding cover 2, the second locking portion 151 presses the third locking portion 24 in the +X direction. When a predetermined force is applied, a component of force in the +Z direction acting on the third inclined surface 24E causes the third locking portion 24 to swing and overcome the second locking portion 151, which makes it easier to prevent the sliding cover 2 from falling off.
[0055] In this embodiment, the first locking portion 23 is capable of swinging from the slide surface 22ss toward the rear surface 22bs of the slide surface 22ss, and the third locking portion 24 is capable of swinging from the slide surface 22ss toward the rear surface 22bs. With this configuration, the first locking portion 23 must swing to overcome the second locking portion 151, and the third locking portion 24 must swing to overcome the second locking portion 151 to release the locked state, which makes it easier to prevent the slide cover 2 from falling off.
[0056] In this embodiment, the slide cover 2 has a first opening 22E1 that opens from the slide surface 22ss to the back surface 22bs of the slide surface 22ss, and a second opening 22E2 that opens alongside the first opening 22E1 in the fourth direction (-X direction) and that opens from the slide surface 22ss to the back surface 22bs, where the first opening 22E1 is a U-shaped opening that sandwiches the first locking portion 23 in the direction (Y direction) along the fifth direction that intersects the first direction (+Z direction) and the second direction (+X direction), and the second opening 22E2 is a U-shaped opening that sandwiches the third locking portion 24 in the Y direction. With this configuration, the first locking portion 23 must swing to overcome the second locking portion 151, and the third locking portion 24 must swing to overcome the second locking portion 151 to release the locked state, which makes it easier to prevent the slide cover 2 from falling off.
[0057] In this embodiment, the cover main body 1 includes a rail portion (first rail portion 15) that bridges the inner surfaces of both side walls in a direction (Y direction) along a fifth direction that intersects the first direction (+Z direction) and the second direction (+X direction), and a pair of first protrusions (upper protrusions 18) that protrude from the inner surfaces of both side walls in the Y direction, and the rail portion (first rail portion 15) slides the sliding cover 2 along the guide surface 15gs, and the first protrusions (upper protrusions 18) restrict the movement of the sliding cover 2 in the first direction (+Z direction). With this configuration, even if a component force in the +Z direction acts on the slide cover 2 due to the inclined surface of the first locking portion 23 or the third locking portion 24, it is easy to suppress movement (rattle) of the slide cover 2 in the first direction (+Z direction).
[0058] In this embodiment, the first protruding portion (upper protruding portion 18) has a second protruding portion (protruding portion 181) that protrudes in the third direction (-Z direction). This configuration makes it easy to suppress movement (rattle) of the slide cover 2 in the first direction (+Z direction), which is expected to be effective in a vibration environment such as a vehicle.
[0059] In this embodiment, the rail portion (first rail portion 15) has a pair of third protrusions (protrusions 1511) that protrude toward the first direction (+Z direction), and the third protrusions (protrusions 1511) are aligned in the second direction (+X direction) with respect to the second locking portion 151. This configuration makes it easy to suppress movement (rattle) of the slide cover 2 in the first direction (+Z direction), which is expected to be effective in a vibration environment such as a vehicle.
[0060] (Variation) In one example of this embodiment, the second locking surface 151B and the first locking surface 23C are surfaces that extend along the +Z direction, but they may also be surfaces that are inclined in a specific direction. For example, first locking surface 23C may be an inclined surface (hereinafter also referred to as "fifth inclined surface 23G") that faces in a direction inclined in the -X direction with respect to the +Z direction. In this case, second locking surface 151B may be an inclined surface (hereinafter also referred to as "sixth inclined surface 151H") that faces in a direction inclined in the +X direction with respect to the -Z direction.
[0061] 18 is a partial enlarged view of portion A in FIG. 13. As shown in FIG. 18, when the sliding cover 2 is slid in the −X direction, the third locking portion 24 climbs over the second locking portion 151, and then the first locking portion 23 and the second locking portion 151 come into contact. In this state, the sixth inclined surface 151H and the fifth inclined surface 23G come into surface contact, causing a component force in the +X direction to be generated in the first locking portion 23. The component force in the −Z direction acting on the fifth inclined surface 23G prevents the first locking portion 23 from climbing over the second locking portion 151. Therefore, the sliding cover 2 is less likely to come off the cover main body 1.
[0062] The above describes an embodiment and modifications. However, the embodiment and modifications are not limited to the above examples. For example, the embodiment and modifications may be realized in combination with each other. [Explanation of symbols]
