[0003] [Patent Document 1] JP 2013-67251 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a vehicle battery fixing structure such as that of Patent Document 1, for example, if the fixing plate, J bolt, and battery bracket are made of metal and a battery with a positive terminal extending from the top surface is used, there is a possibility that a short circuit will occur due to contact between the metallic battery band and the positive terminal when the vehicle collides. Also, in recent years, due to stricter collision performance, a metal tray is used to prevent the mounting part of the battery from being damaged, and a J bolt is fixed to the fixing plate and the metal tray, and in this case, there is a possibility of a short circuit.

[0005] In view of the above problems, the present invention has an object to provide a vehicle battery fixing structure that prevents a short circuit caused by contact between the positive terminal and a metal battery band. [Means for solving the problem]

[0006] In order to solve the above problems, a representative configuration of the present invention is a battery fixing structure for a vehicle comprising a battery having a positive terminal on its upper surface, a metallic battery band suspended across the upper surface of the battery, and first and second metallic fixing members fixed to both ends of the battery band, extending downward from the ends along the sides of the battery and fixed in electrical conductivity to specified members of the vehicle body, the vehicle battery fixing structure further comprising a resin cover that covers the battery band, the cover covering at least an area of ​​the side of the battery band that intersects with an imaginary perpendicular line extending from the positive terminal of the battery toward the battery band in a planar view. Effect of the Invention

[0007] According to the present invention, it is possible to provide a vehicle battery fixing structure that prevents a short circuit caused by contact between the positive terminal and a metal battery band. [Brief description of the drawings]

[Diagram 5] FIG. 2 is a plan view of the vehicle battery fixing structure of FIG. [Figure 6] FIG. 2 is a front view of the vehicle battery fixing structure of FIG. [Figure 7] 2 is a perspective view of the vehicle battery fixing structure in a state where a cover is attached to the positive terminal of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] One embodiment of the present invention is a battery fixing structure for a vehicle comprising a battery having a positive terminal on its upper surface, a metallic battery band spanned across the upper surface of the battery, and first and second metallic fixing members fixed to both ends of the battery band, extending downward from the ends along the sides of the battery and fixed in electrical conductivity to specified members of the vehicle body, the vehicle battery fixing structure further comprising a resin cover that covers the battery band, the cover covering at least an area of ​​the side of the battery band that intersects with an imaginary perpendicular line extending from the positive terminal of the battery toward the battery band in a planar view.

[0010] According to the present invention, the resin cover covers at least the area of ​​the side of the metal battery band that intersects with a virtual perpendicular line extending from the positive terminal of the battery toward the battery band in a plan view. Therefore, at least the area of ​​the side of the metal battery band that may come into contact with the positive terminal is covered by the resin cover. As a result, a short circuit caused by contact between the positive terminal and the metal battery band is prevented.

[0011] Both ends of the battery band are wider than the center, and the above-mentioned area of ​​the side of the battery band connects one end of the battery band to the center while being inclined when viewed in a plane, and the cover has a side wall that covers the side of one end of the battery band to follow its outline, and a convex portion that is continuous with the side wall and is formed flush with the side wall, covers the above-mentioned area, and is recessed in a step shape just before the center of the battery band, thereby protruding relative to the above-mentioned area of ​​the battery band.

[0012] According to the above configuration, the cover has a convex portion that covers the inclined region of the side of the battery band, i.e., the region that may come into contact with the positive terminal. This convex portion is formed to be continuous with the side wall and flush with the side wall to cover the above region. Therefore, the convex portion protrudes from the region of the battery band until it moves away from the inclined region from one end of the battery band toward the center and is recessed in a step shape at the center of the battery band. When the vehicle collides and the battery receives an impact from the outside, the positive terminal hits the convex portion. If the cover does not have a convex portion and the cover only covers the inclined region of the battery band along its outer shape, the positive terminal that comes into contact with the cover may move in the length direction of the battery band toward the center of the battery band. However, according to the above configuration, even if the positive terminal hits the convex portion, it is prevented from moving further in the length direction of the battery band.

[0013] The battery band is preferably formed so that it becomes higher from both ends toward the center, and the side walls and protrusions of the cover are preferably formed so that they become higher from one end of the battery band toward the center in accordance with the change in height of the upper surface of the battery band.

[0014] According to the above configuration, the side walls and the protrusions of the cover are formed so that they become higher from one end of the battery band to the center in accordance with the change in height of the upper surface of the battery band. Therefore, the area of ​​the side walls and the protrusions of the cover where the positive terminal contacts the cover becomes larger toward the center in the length direction of the battery band, and the area of ​​the positive terminal contacts the cover becomes smaller toward the one end in the length direction of the battery band. Therefore, the load applied to the positive terminal is received by a larger area of ​​the cover toward the center in the length direction of the battery band. As a result, the stress concentration on the positive terminal is reduced as it approaches the center in the length direction of the battery band, and damage to the positive terminal is prevented.

[0015] The cover may further include a rib formed on the inner side of the protrusion and perpendicular to the side wall in a plan view.

[0016] According to the above-mentioned configuration, the rib extends perpendicular to the side wall inside the protrusion, improving the rigidity of the protrusion, thereby further preventing damage to the cover when the positive terminal hits the protrusion of the cover. EXAMPLES

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0018] Fig. 1 is a perspective view of a vehicle battery fixing structure 100 according to an embodiment of the present invention. In Fig. 1 and all other drawings, the front-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up-down direction is indicated by arrows U (Upward) and D (Downward).

[0019] A vehicle battery fixing structure 100 shown in FIG. 1 includes a tray 101 and a battery 102 mounted thereon.

[0020] The tray 101 is fixed to a support member 110 (a specified member) fixed to the front side of the vehicle. In this embodiment, the following description will be given assuming that the side on which the support member 110 is drawn is the front of the vehicle. The tray 101 is made of metal. The tray 101 has a mounting plate 101a, a first flange 101b, and a second flange 101c. The mounting plate 101a extends in the horizontal direction and is a portion on which the battery 102 is mounted. The first flange 101b is a portion bent upward from each of both ends of the mounting plate 101a in the vehicle width direction. The second flange 101c is a portion bent upward from each of both ends of the mounting plate 101a in the vehicle front-rear direction. A hole 101d is formed in the first flange 101b.

[0021] The battery 102 has a positive terminal 102b and a negative terminal 102c on the upper surface 102a. In this embodiment, the positive terminal 102b is located on the vehicle front side of the upper surface 102a of the battery 102. The negative terminal 102c is located on the vehicle rear side of the upper surface 102a of the battery 102. The battery 102 also has a liquid injection port (not shown) for injecting an electrolyte and a cap 102d for closing the liquid injection port on the upper surface 102a. Since there are six cells for obtaining a voltage of 2V, there are six caps 102d. The cap 102d is molded from resin. Furthermore, an anti-slip sheet 102e is attached to both ends of the upper surface 102a of the battery 102 in the vehicle width direction and in the center in the vehicle front-rear direction. The anti-slip sheet 102e is a sheet that prevents a battery band 105 described later from slipping on the upper surface 102a. The battery band 105 is arranged so that both ends straddle the two anti-slip sheets 102e.

[0022] Fig. 2 is a perspective view showing the positional relationship between the cover 106 in Fig. 1 and the battery band 105 covered by it. As shown in Fig. 2, the vehicle battery fixing structure 100 also includes the cover 106 and the battery band 105. The battery band 105 is not shown in Fig. 1 because it is covered by the cover 106.

[0023] As shown in FIG. 1, the vehicle battery fixing structure 100 further includes a first fixing member 103 and a second fixing member 104. The first fixing member 103 is a metal member extending upward from the tray 101 along one side of the battery 102. The first fixing member 103 has an engagement portion 103a and a screw portion 103b (see FIG. 2). The engagement portion 103a is a portion bent into a J-shape at the lower end side. The engagement portion 103a is engaged with a hole 101d of one first flange 101b of the tray 101, so that the engagement portion 103a is attached to the tray 101 so as to be able to swing.

[0024] In addition, in this embodiment, the engagement portion 103a of the first fixing member 103 is fixed to the hole 101d of the metal tray 101 on which the battery 102 is placed, but instead, the engagement portion 103a of the first fixing member 103 may be fixed to a hole of a metal bracket or the like (not shown) (a support member 110 is also possible) that further supports, for example, a resin tray that supports the battery 102.

[0025] As shown in FIG. 2, the screw portion 103b is a screw portion formed on the upper end side of the first fixing member 103. The screw portion 103b is passed through a hole 105a (see FIG. 3(a)) at one end of the battery band 105, and is fixed by a washer 111 (see FIG. 3(b)) and a nut 112 (see FIG. 3(b)). As a result, the first fixing member 103 extends downward from one end of the battery band 105 described below along the side surface of the battery 102 and is fixed to a predetermined member of the vehicle in an electrically conductive manner. The screw portion 103b is also passed through a hole 106a (see FIG. 4(a)) of the cover 106, and is also fixed by a washer 165 (see FIG. 1) and a nut 166 (see FIG. 1). In this embodiment, the first fixing member 103 is provided separately from the vehicle body, but may be configured to be directly fixed to the vehicle body.

[0026] Similarly, as shown in FIG. 1, the second fixing member 104 is a metal member extending upward from the tray 101 along the other side surface of the battery 102. The second fixing member 104 has an engagement portion 104a and a screw portion 104b (see FIG. 2). The engagement portion 104a is a portion bent into a J-shape at the lower end side. The engagement portion 104a is attached to the tray 101 so as to be able to swing relative to the tray 101 by engaging with a hole 101d of the other first flange 101b of the tray 101.

[0027] In addition, in this embodiment, the engagement portion 104a of the second fixing member 104 is fixed to the hole 101d of the metal tray 101 on which the battery 102 is placed, but instead, the engagement portion 104a of the second fixing member 104 may be fixed to a hole of a metal bracket or the like (not shown in the figure) (which may also be a support member 110) that further supports, for example, a resin tray that supports the battery 102.

[0028] As shown in FIG. 2, the screw portion 104b is a screw portion formed on the upper end side of the second fixing member 104. The screw portion 104b is passed through a hole 105a (see FIG. 3(a)) at the other end of the battery band 105, and is fixed by a washer 111 (see FIG. 3(b)) and a nut 112 (see FIG. 3(b)). As a result, the second fixing member 104 extends downward from the other end of the battery band 105 described later along the side surface of the battery 102 and is fixed to a predetermined member of the vehicle in an electrically conductive manner. The screw portion 104b is also passed through a hole 106a (see FIG. 4(a)) of the cover 106, and is also fixed by a washer 165 (see FIG. 1) and a nut 166 (see FIG. 1). In this embodiment, the second fixing member 104 is provided separately from the vehicle body, but may be configured to be directly fixed to the vehicle body.

[0029] Fig. 3 is a plan view and a front view of the battery band 105 of Fig. 2. Fig. 3(a) is a plan view of the battery band 105. Fig. 3(b) is a plan view of the battery band 105 of Fig. 3(a) with a washer 111 and a nut 112 added. Fig. 3(c) is a front view of the battery band 105 of Fig. 3(a). The battery band 105 is a metal band that is hung across the upper surface 102a of the battery 102. The battery band 105 has a band bottom plate 151 and band side plates 152, and is formed with a U-shaped cross section.

[0030] As shown in FIG. 3, the battery band 105 has two end regions A on the end sides, a central region B on the central side, and two inclined regions C between the end regions A and the central region B.

[0031] As shown in FIG. 3(a), the band bottom plate 151 has two bottom plate end portions 151a, a bottom plate central portion 151b, and two bottom plate inclined portions 151c. The bottom plate end portions 151a are located in the end portion area A and are formed to be wide. A hole 105a is formed in each of the bottom plate end portions 151a. The dimension between the two holes 105a is set to be larger than the width of the upper surface 102a of the battery 102. As shown in FIG. 3(b), a washer 111 and a nut 112 are disposed on each of the holes 105a. The bottom plate central portion 151b is located in the central portion area B and is formed to be narrow. The bottom plate inclined portion 151c is located in the inclined portion area C and connects the bottom plate end portions 151a and the bottom plate central portion 151b, and is formed to be wide on the bottom plate end portion 151a side and narrow on the bottom plate central portion 151b side.

[0032] As shown in Fig. 3(a) and Fig. 3(c), the band side plate 152 has two side plate end portions 152a, a side plate central portion 152b, and two side plate inclined portions 152c. The side plate end portions 152a are located in the end portion area A in Fig. 3(a) and Fig. 3(c), and are portions bent upward from both ends in the width direction of the bottom plate end portion 151a. The width W1 between the side plate end portions 152a is set wider than the width W2 between the center portions 152b. Note that, as a result, the widths of both ends of the battery band 105 are wider than the width of the center of the battery band 105.

[0033] The side plate central portion 152b is located in the central region B in Fig. 3(a) and Fig. 3(c) and is a portion bent upward from both ends in the width direction of the bottom plate central portion 151b. The width W2 between the center portions 152b of the side plate of the battery band 105 is set narrow in order to form a shape that avoids the cap 102d.

[0034] The side plate inclined portion 152c is located in the inclined portion region C in Figures 3(a) and 3(c), and is a portion bent upward from both ends in the width direction of the bottom plate inclined portion 151c. In a plan view, the side plate inclined portion 152c connects the side plate end portion 152a (one end) and the side plate central portion 152b (center portion) while being inclined. The side plate inclined portion 152c is formed so that the boundary side with the side plate end portion 152a is wide and the boundary side with the side plate central portion 152b is narrow.

[0035] 3(c), the height H2 of the side plate central portion 152b is set higher than the height H1 of the side plate end portion 152a. In addition, the upper end of the side plate inclined portion 152c is connected to the upper end of the side plate end portion 152a (one end) and the upper end of the side plate central portion 152b (center portion) while being inclined when viewed from the front. Therefore, the battery band 105 is formed so as to become higher from both ends toward the center.

[0036] The cover 106 shown in Fig. 2 is a resin member that covers the battery band 105. Here, the cover 106 will be further described with reference to Fig. 4. Fig. 4 is a plan view, a front view, and a back view of the cover 106 in Fig. 2. Fig. 4(a) is a plan view of the cover 106. Fig. 4(b) is a front view of the cover 106. Fig. 4(c) is a back view of the cover 106.

[0037] As shown in FIG. 4(a) to FIG. 4(c), the cover 106 has an end region a, a central region b, and a width-changing region c. The end region a is set to have a wide width, and the central region b is set to have a narrow width. The width-changing region c is a region between the end region a and the central region b, and is set to be wide on the end region a side and narrow on the central region b side. The cover 106 has a side wall 161a, a convex portion 161b, an inclined wall 161c, and a vertical wall 161d. The cover 106 also has a first ceiling wall 162a, an intermediate ceiling wall 162b, and a second ceiling wall 162c. The cover 106 is formed in an inverted U-shaped cross section.

[0038] The side wall 161a is located in the end region a and is a wall that covers the side surface of one end of the battery band 105 so as to follow the outer shape of the side wall. The side wall 161a is formed in a flat plate shape. As shown in FIG. 4(b), the height h1 of the side wall 161a is lower than the height h2 of the middle ceiling wall 162b.

[0039] The protrusion 161b is located in the width change region c, continues from the side wall 161a, and is formed flush with the side wall 161a to cover the side plate inclined portion 152c (region) of the battery band 105. The protrusion 161b is recessed in a step shape before reaching the intermediate ceiling wall 162b (before the center of the battery band 105). Therefore, the protrusion 161b protrudes from the side plate inclined portion 152c of the battery band 105. In a plan view, the angle of the protrusion 161b with respect to the length direction of the cover 106 is steeper than the angle of the side plate inclined portion 152c with respect to the length direction of the battery band 105. Also, as shown in FIG. 4(b), the protrusion 161b and the above-mentioned side wall 161a are formed so as to become higher from one end to the center in the length direction of the battery band 105.

[0040] Here, the arrangement of the protrusion 161b will be described with reference to Fig. 5. Fig. 5 is a plan view of the vehicle battery fastening structure 100 of Fig. 1. As shown in Fig. 5, the protrusion 161b covers at least an area of ​​the side surface of the battery band 105 in the cover 106 that intersects with a virtual perpendicular line P extending from the positive terminal 102b of the battery 102 toward the battery band 105 in the cover 106 in a plan view. The area of ​​the protrusion 161b also covers the side plate inclined portion 152c of the battery band 105.

[0041] In this embodiment, the direction in which the virtual perpendicular line P extends is the front-rear direction of the vehicle. In addition, in this embodiment, the direction in which the virtual perpendicular line P extends can be said to be the direction in which the battery 102 is pushed while being sandwiched between the first fixing member 103 and the second fixing member 104 when the vehicle collides. In addition, the direction in which the virtual perpendicular line P extends can be said to be the direction of a line that can be drawn from the positive terminal 102b to the battery band 105 in the shortest distance in a plan view.

[0042] The positive terminal 102b and the negative terminal 102c of the battery 102 may be arranged at an interval in the vehicle width direction (left and right), and the battery band 105 and the cover 106 may be arranged to extend in the vehicle front-rear direction. In this case, the direction in which the imaginary perpendicular line P extends is the vehicle width direction. In this way, as long as the positional relationship of the positive terminal 102b of the battery 102, the negative terminal 102c of the battery 102, the battery band 105, and the cover 106 in FIG. 5 is maintained, it does not matter which side of the battery 102 faces the front of the vehicle.

[0043] The battery band 105 is provided with two protrusions 161b. The two protrusions 161b are arranged at positions that are point-symmetrical with respect to the center O of the battery band 105. If there is only one protrusion 161b, when the user mistakenly fixes one end and the other end of the battery band 105 to the battery 102 in the opposite direction, the protrusion 161b may not be positioned to face the positive terminal 102b. This is to prevent the user from attaching the cover 106 in the wrong position so that the function of the protrusion 161b cannot be exerted. In other words, if there are two protrusions 161b, even if the user fixes one end and the other end of the battery band 105 to the battery 102 in the opposite direction, the protrusion 161b will always be positioned to face the positive terminal 102b.

[0044] As shown in Figures 4(a) and 4(c), the inclined wall 161c is located in the width changing region c, and in plan view, it is connected to the protruding portion 161b via the intermediate ceiling wall 162b, and the width gradually increases from one end to the other end. Also, as shown in Figure 4(b), the inclined wall 161c becomes gradually lower from one end to the other end in front view.

[0045] The vertical wall 161d is a wall that covers the side surface of the other end of the battery band 105 so as to follow its outer shape. The vertical wall 161d is formed in a flat plate shape. As shown in FIG. 4(b), the height h1 of the vertical wall 161d is the same as that of the side wall 161a, and is lower than the height h2 of the intermediate ceiling wall 162b. In this embodiment, the cover 106 has the side wall 161a, the convex portion 161b, the inclined wall 161c, and the vertical wall 161d. However, for example, it is also possible to have only the convex portion 161b, or only the convex portion 161b and the side wall 161a.

[0046] 4(c), the cover 106 further has a rib 161e. The rib 161e is formed on the inner side of the protruding portion 161b. The rib 161e extends in a direction perpendicular to the side wall 161a in a plan view.

[0047] The width w1 between the opposing side wall 161a and the vertical wall 161d is wider than the width w2 at the center of the intermediate ceiling wall 162b. Therefore, the width of the end side of the cover 106 is wider than the width of the center side of the cover 106.

[0048] The first ceiling wall 162a is located in the end region a and is a wall that connects the upper ends of the side walls 161a and the vertical walls 161d that face each other. The second ceiling wall 162c is located in the width change region c and is a wall that connects the upper ends of the convex parts 161b and the inclined walls 161c that face each other. The middle ceiling wall 162b is located in the central region b and is a wall that connects the second ceiling wall 162c on one side of the cover 106 and the second ceiling wall 162c on the other side of the cover 106. The middle ceiling wall 162b of the cover 106 is set narrow in order to avoid the cap 102d. The lower part of the middle ceiling wall 162b is perforated. In this embodiment, the lower part of the middle ceiling wall 162b is perforated, but the lower part of the middle ceiling wall 162b may be configured not to be perforated and may be made of a plate material that is continuous with the convex parts 161b and the inclined walls 161c.

[0049] Here, the height of the protrusion 161b will be described with reference to FIG. 6. FIG. 6 is a front view of the vehicle battery fastening structure 100 of FIG. 1. The side wall 161a and the protrusion 161b of the cover 106 are formed so as to become higher from one end of the battery band 105 toward the center in accordance with the change in height of the upper surface of the battery band 105. The height of the protrusion 161b is higher than the height of the side wall 161a except at the boundary with the side wall 161a. Therefore, the positive terminal 102b can be received over a wider surface when the positive terminal 102b collides with the protrusion 161b than when the positive terminal 102b collides with the side wall 161a.

[0050] Next, the operation when the vehicle collides and the battery 102 is pushed from the front to the rear of the vehicle will be described with reference to Fig. 7. Fig. 7 is a perspective view of the vehicle battery fixing structure 100 with the cover 106 attached to the positive terminal 102b in Fig. 1. In the vehicle battery fixing structure 100, the positive terminal 102b is covered with a terminal cover 171 and is clamped by a clip (not shown) and connected to a cable 172, and the negative terminal 102c is clamped by a clip 173 and connected to a cable 174.

[0051] When the front part of the vehicle collides, the battery 102 is pushed toward the rear of the vehicle. In this case, the terminal cover 171 comes off the positive terminal 102b, resulting in the state shown in FIG. 1, and then the positive terminal 102b comes into contact with the protruding portion 161b of the cover 106. The positive terminal 102b gets caught on the protruding portion 161b of the cover 106 and cannot move any further toward the rear of the vehicle. At this time, the positive terminal 102b does not come into contact with the battery band 105 due to the presence of the protruding portion 161b of the cover 106.

[0052] According to this embodiment, the resin cover 106 covers at least the area of ​​the side of the metal battery band 105 that intersects with the imaginary perpendicular line P extending from the positive terminal 102b of the battery 102 toward the battery band 105 in a plan view. Therefore, at least the area of ​​the side of the metal battery band 105 that may come into contact with the positive terminal 102b is covered by the resin cover 106. As a result, a short circuit caused by contact between the positive terminal 102b and the metal battery band 105 is prevented. Furthermore, the occurrence of a fire is prevented.

[0053] According to this embodiment, the cover 106 has a protrusion 161b that covers the inclined region of the side surface of the battery band 105, i.e., the region that may come into contact with the positive terminal 102b. This protrusion 161b is continuous with the side wall 161a and is formed flush with the side wall 161a to cover the above-mentioned region. Therefore, the protrusion 161b protrudes from the above-mentioned region of the battery band 105 from one end toward the center of the battery band 105, away from the above-mentioned inclined region, until it is recessed in a step shape just before the center of the battery band 105. When the vehicle collides and the battery 102 receives an impact from the outside, the positive terminal 102b comes into contact with the protrusion 161b. If the cover 106 did not have the protrusion 161b and simply covered the inclined area of ​​the battery band 105 along its outer shape, the positive terminal 102b that came into contact with the cover 106 would move in the length direction of the battery band 105 toward the center of the battery band 105. However, according to this embodiment, even if the positive terminal 102b comes into contact with the protrusion 161b, it is prevented from moving any further in the length direction of the battery band 105.

[0054] Also, according to this embodiment, the side wall 161a and the protrusion 161b of the cover 106 are formed so as to become higher from one end of the battery band 105 to the center in accordance with the change in height of the upper surface of the battery band 105. Therefore, for the side wall 161a and the protrusion 161b of the cover 106, the area where the positive terminal 102b contacts the cover 106 becomes larger toward the center in the length direction of the battery band 105, and the area where the positive terminal 102b contacts the cover 106 becomes smaller toward the one end side in the length direction of the battery band 105. Therefore, the load applied to the positive terminal 102b is received by a wider area of ​​the cover 106 toward the center in the length direction of the battery band 105. As a result, the closer to the center in the length direction of the battery band 105, the less stress concentration is applied to the positive terminal 102b, and damage to the positive terminal 102b is prevented.

[0055] In addition, according to this embodiment, the rib 161e extends inside the protrusion 161b perpendicular to the side wall 161a, improving the rigidity of the protrusion 161b. As a result, when the positive terminal 102b hits the protrusion 161b of the cover 106, damage to the cover 106 is further prevented.

[0056] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0057] Furthermore, the present invention can be implemented by freely combining the inventions described in the claims and examples, regardless of the dependent relationships of the claims. [Industrial Applicability]
