Description

Charging equipment for vehicles installed on a fixed platform

[0001] The present invention relates to charging equipment for vehicles installed on a fixed platform. That is, the present invention relates to charging equipment for charging a vehicle having a power storage device such as a battery. Preferably, although not necessarily limited thereto, the present invention relates to charging equipment for electric vehicles (hereinafter also referred to as EVs) and so-called plug-in hybrid vehicles. Note that the use of the vehicle is not limited. The present invention relates to charging equipment used for private cars, business-use vehicles, vehicles used in agriculture such as tractors and lawn mowers, and electric scooters.

[0002] In some cases, electrical equipment such as chargers and transformers is installed outdoors. In particular, in recent years, with the spread of EVs, the opportunities for installing EV chargers outdoors have been increasing. When installing such electrical equipment as chargers outdoors, a method of installing a base and fixing the electrical equipment thereon is generally adopted. For example, Patent Document 1 discloses a fixing method characterized by including steps of arranging each of a plurality of support members for supporting the housing from below at a position corresponding to a fixing portion of a bottom cover in a state where the detachable bottom cover is removed from the bottom surface of the housing, attaching the fixing portion to each of the arranged plurality of support members, and attaching the bottom surface of the housing to the bottom cover to which the fixing portion has been attached to each of the plurality of support members.

[0003] Japanese Patent Application Laid-Open No. 2017-220534

[0004] The fixing method of Patent Document 1 requires complicated steps such as positioning of support members and attachment of fixing portions at the site where the electrical equipment is installed. Further, when the electrical equipment is fixed by the fixing method, cables such as electric wires connected to the electrical equipment are exposed, and there are not a few cases where they are damaged by wild animals or the like. Furthermore, when trying to reduce such damage, it is generally practiced to bury the cables such as cables underground, but such cable burying work requires large-scale civil engineering work using equipment, making the installation work of the electrical equipment more difficult.

[0005] As a result of diligent research by the inventors, the above problem can be solved by EV charging equipment fixed to a fixed base of a specific structure, leading to the present invention. In the following description, charging equipment is sometimes described using the broader concept of electrical equipment. This is because, although the present invention was completed by developing EV charging equipment for eco-cars which will become mainstream in the future, it is believed that it can be applied not only to charging equipment but also to electrical equipment. On the other hand, it can also be applied to hydrogen supply equipment in hydrogen refueling stations for hydrogen-powered vehicles. In other words, the present invention relates to: [1] an electric vehicle charging station having a base member, a spacer member, a cover member and a fixing member, wherein the base member has a spacer member on its upper side, the spacer member has a cover member on its upper side, the electrical equipment is fixed by the fixing member, there is a space inside surrounded by the base member, the spacer member and the cover member, the cables of the electrical equipment are arranged in the space, and the electric vehicle charging station is fixed to the base; [2] an electric vehicle charging station installed on the base according to [1], wherein the fixing member penetrates the cover member from above the base member and fixes the electrical equipment; [3] an electric vehicle charging station installed on the base according to [1] or [2], wherein the fixing member supports the electrical equipment; [4] an electric vehicle charging station installed on the base according to [1] or [2], wherein a member having a height adjustment function is installed on the base; [5] The EV charging equipment according to [1] or [2], characterized in that the electrical equipment has support columns, or the cover member has support columns, and the electrical equipment is fixed to these support columns with fixing members. Even if these support columns are considered to be independent support members, they are still within the scope of the present invention.[6] An EV charging facility installed on a fixed base according to [1] or [2], characterized in that the cable is arranged without touching the ground; [7] An EV charging facility installed on a fixed base according to [1] or [2], characterized in that the cable is arranged horizontally in the space; [8] An EV charging facility installed on a fixed base according to [1] or [2], characterized in that the fixed base for the electrical equipment has multiple electrical equipment units; [9] An EV charging facility installed on a fixed base according to [8], characterized in that a cable connecting multiple electrical equipment units is connected through the space;

[10] A method for installing an EV charging facility installed on a fixed base according to [1] or [2], characterized in that burying work for the cables of the electrical equipment is not required;

[11] An EV charging facility according to [1] or [2], characterized in that the EV charging facility is fixed to the fixed base.

[0006] The mounting base for electrical equipment of the present invention can be assembled in a factory or similar facility and then transported to the site for installation, making installation easy. Furthermore, since large-scale civil engineering work such as cable burial is not required for installation, the installation of electrical equipment can be carried out much more easily and quickly than with conventional mounting bases. In addition, because the mounting base of the present invention has a simple structure, the attachment and detachment of electrical equipment is easy.

[0008] Preferred embodiments of the present invention will be described with reference to the drawings. It goes without saying that the present invention is not limited to the following embodiments and aspects, and various modifications are possible within the technical scope of the present invention. Furthermore, "up and down," "front and back," and "left and right" in this text refer to the directions shown in each drawing.

[0009] Figure 1 shows a specific example of a fixed base (hereinafter simply referred to as "fixed base") used in electrical equipment (in this specification, car charging equipment may be simply referred to as "electrical equipment") of the present invention. The fixed base 1 in Figure 1 includes a base member 2 having at least an upper surface, a spacer member 3 installed on the upper surface of the base member 2, a cover member 4 covering at least the spacer member 3 while leaving space around the spacer member 3, and a fixing member 5 protruding substantially vertically from the upper surface of the base member 2, penetrating the cover member 4 and being exposed to the outside. Further embodiments of the fixed base 1 of the present invention are shown in Figure 7. The fixed base 1 in Figure 7 includes a base member 2 having at least an upper surface, a spacer member 3 installed on the upper surface of the base member 2, and a cover member 4 that covers at least the spacer member 3 while leaving space around it. Holes 23 and 41 are provided in the base member 2 and the cover member 4, respectively, and the centers of the holes 23 in the base member 2 and the holes 41 in the cover member 4, as viewed from the planar direction, coincide. The components will be described in detail below.

[0010] 1. Base Member 2 The base member 2 is a member having at least a flat surface on its upper side. The base member 2 is a base that supports the spacer member 3, which will be described later, and is also a base that supports the cables of the electrical equipment fixed to the fixing base 1 so that they do not come into direct contact with the ground. The base member 2 is also a member that serves as the foundation for fixing the cover member 4, which will be described later, as needed. The shape of the base member 2 can be adjusted as appropriate according to the terrain of the place where the electrical equipment is to be installed. For example, as shown in Figures 2(A) to (C), the planar shape of the base member 2 can be made rectangular, and if the place where the electrical equipment is to be installed is flat, the lower side of the base member 2 can be made a flat surface. If the place where the electrical equipment is to be installed has a slope, for example, it can be made sloped in the left-right direction and / or front-back direction, as shown in Figures 2(D) to (E). If there are fine irregularities at the installation site, fine irregularities can be provided on the lower surface of the base member 2 (not shown). Furthermore, the shape of the base member 2 as viewed from the planar direction may be a polygon including a triangle, a rectangle, a quadrilateral, a pentagon, and a hexagon, or a circle including an ellipse. Also, the shape of the base member 2 as viewed from the planar direction may be a shape that has length in the front-to-back or left-to-right direction, for example, a rectangle or an ellipse. The upper side of the base member 2 may have protrusions or irregularities (not shown), provided that it has a flat surface that allows for the installation of the spacer member 3, as will be described later. The base can be a ladder structure base installed on the lower surface of the spacer member, as long as it can support the electrical equipment. In other words, this is an embodiment in which the base has a structure that bridges the spacer member (this is sometimes referred to as a ladder structure in this specification). In this case, since the ladder structure member is a base or has the function of a base, it is not necessarily required to provide a concrete base further below it. If the material constituting the ladder structure is, for example, a steel frame that is not very thick, the weight of the fixed base can be reduced.

[0011] The material of the base member 2 is not particularly limited, provided that it can withstand the mass of the electrical equipment to be installed and the spacer member 3 described later. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood. Among these, concrete is more preferable because it is less affected by the humidity and other environmental factors of the installation site and is relatively easy to process.

[0012] Furthermore, the base member 2 used in the present invention may include a groove 21 on its upper surface and a latching portion 22 that protrudes from near the upper end of the groove 21 toward the center of the groove. Figure 3 shows an example of the form of the base member 2 including the groove 21 and the latching portion 22. As shown in Figures 3(A) to (C), a groove 21 extending in the front-rear direction is provided approximately in the left-right center of the base member 2. In addition, the latching portion 22 protrudes from near the left and right upper ends of the groove 21 toward approximately the left-right center of the groove 21. The groove 21 and the latching portion 22 are used when fixing the fixing member 5 to the base member 2, as will be described later. The shape of the latching portion 22 is not particularly limited as long as it is a shape that allows the fixing member 5 to be fixed using a nut or the like, as will be described later. Furthermore, the groove 21 and the latching portion 22 may be formed by cutting or the like after the base member 2 is manufactured, or a mold may be used to form the groove 21 and the latching portion 22 when forming the base member 2. The shape of the groove 21 when viewed from the planar direction may be a straight line or a bent line, as shown in Figure 3. Similarly, the shape of the groove 21 when viewed from the front may be a polygon, such as a quadrilateral as shown in Figure 3, or a semicircle. The base member 2 having the groove 21 and the latching portion 22 may be used to fix the fixing member 5 as described above, or it may be used to fix the spacer member 3 as described later.

[0013] 2. Spacer member 3 The spacer member 3 is a member installed on the upper plane of the base member 2. By installing the spacer member 3 on the base member 2, a space is secured between the base member 2 and a cover member 4 described later. The material of the spacer member 3 can be appropriately selected on the condition that it can withstand the mass of the electrical equipment installed on the fixed base 1. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood. Regarding its shape, it can be appropriately adjusted according to the material on the condition that it can withstand the mass of the electrical equipment installed on the fixed base 1 and a space for arranging cables of the electrical equipment can be secured as described later. As a specific shape of the spacer member 3, for example, as shown in FIGS. 4(A) and (B), it may be a rod-shaped member having a length. Also, as shown in FIGS. 4(C) and (D), it may be a plate-shaped member having a thickness with an elliptical planar shape. Furthermore, it may be a rod-shaped member having a length with a shape that can secure more space so that it looks like a "工" character or a "コ" character when viewed from the front direction (it is a "工" character in FIGS. 4(E) and (F)).

[0014] Incidentally, since the spacer member connects the base member and the cover member and forms a space for storing the cable of the charging equipment which is a feature of the present invention, it may also be referred to as a connecting member, and the scope of the present invention is not limited by this name.

[0015] The spacer member (also referred to as a connecting member) can use H-shaped steel or C-shaped steel. It may be arranged so as to surround the periphery of the base, or may be arranged on a part thereof. For example, in the case where the base member is a three-dimensional structure object having a cube, a rectangular parallelepiped, or a polyhedral structure, it may be arranged so as to surround all its sides, or may be arranged on only an arbitrary side that is a part thereof, or a part of an arbitrary side. Incidentally, the spacer member may be integrally formed with the base member and / or a cover member described later. And the cross-section of the space formed by these three members is not limited. This cross-section is preferably a quadrilateral including a square. It is also preferable that it is a polygon. There may be cases of a circle or a semi-circle. There may also be cases where it has a line and a curve.

[0016] 3. Cover Member 4 The cover member 4 is a member that covers at least the spacer member 3 while leaving space around it. The material of the cover member 4 can be appropriately selected, provided that it can withstand the mass of the electrical equipment installed on the fixing base 1. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood. The shape of the cover member 4 is not particularly limited, provided that it can cover at least the spacer member 3. For example, it may be a plate-shaped member whose shape when viewed from a planar direction is a polygon such as a triangle, square, pentagon, or hexagon, or a circle including an ellipse. The cover member 4 has holes 41 through which the fixing member 5 will pass, as will be described later. In addition, the cover member 4 may have holes 41' through which cables of the electrical equipment fixed to the fixing base 1 will pass, if necessary. The holes 41 and 41' can be drilled in advance, or they can be drilled after the cover member 4 is fixed to the fixing base 1, as will be described later. In addition, by processing at least the surface of the cover member 4 with irregularities, the possibility of accidents such as workers slipping when fixing the electrical equipment to the fixing base 1 can be reduced.

[0017] 4. Fixing Member 5 Fixing member 5 is a member that fixes the charging equipment. Bolts are preferred. The number of bolts used for fixing is not limited. It is preferable that it be fixed in one place (one bolt in the case of bolts). It is also possible to fix it in multiple places (for example, two, three, four, five, six, seven, or eight bolts). The relative positions of the bolts are not particularly limited. A structure that can be fixed by passing through the cover member is preferred. It is also acceptable if it is fixed without passing through the cover member, but is located on its upper surface (the surface on which the electrical equipment to be fixed is located), and can support the weight of the charging device equipment. It is also preferable that it is a member that protrudes substantially vertically from the upper plane of the base member 2 as shown in Figure 1, and penetrates the cover member 4 to be exposed to the outside. Here, "substantially vertical" means an angle such that the electrical equipment can be fixed by the fixing member 5 that has passed through the cover member 4. Therefore, it is of course included when the angle between the plane of the base member 2 and the axial direction of the fixing member 5 is right angle, but it is also included angles other than vertical that are such that the electrical equipment can be fixed by the fixing member 5. The fixing member 5 is a member for fixing electrical equipment which will be fixed to the fixing base 1 as described later. Specific examples of such members include, for example, bolts or pins for fastening. The material of the fixing member 5 can be appropriately selected, provided that it can support the electrical equipment installed on the fixing base 1 so that it does not move. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, and resin materials such as acrylic.

[0018] 5. Specific Example of Fixing Base 1 Figure 1 shows a specific example of fixing base 1. In the fixing base 1 shown in Figure 1, two spacer members 3 made of steel H-beams are installed parallel to each other on the upper surface of a base member 2 made of concrete, which has flat upper and lower surfaces. The spacer members 3 are fixed to the base member 2 by fasteners 31 (bolts in Figure 1). A fixing member 5 (bolt in Figure 1), consisting of a shaft portion 51 and a head portion 52, is embedded in the base member 2 with the head portion 52 facing downwards. The shaft portion 51 of the fixing member 5 extends from the upper plane of the base member 2 in a direction substantially perpendicular to the direction of that plane. The base member 2 and the spacer members 3 are surrounded by a cover member 4, and space is secured around the spacer members 3. In Figure 1, the spacer members 3 are surrounded together with the base member 2 by the cover member 4, but the cover member 4 may be used to surround only the spacer members 3. In this case, it is preferable to ensure a space between the cover member 4 and the spacer member 3 sufficient to allow cables such as electric wires of electrical equipment fixed to the base 1, as described later, to pass through. More preferably, as mentioned above, it is preferable that the cover member 4 surrounds the base member 2 and the spacer member 3 together. By doing so, the unevenness of the base 1 is reduced, the overall strength of the base 1 is increased, and accidents such as workers tripping during installation can be avoided.

[0019] The cover member 4 in Figure 1 is a box-shaped structure without a bottom, formed by welding together checkered steel plates with a rectangular planar shape, and is installed by placing it over the base member 2 and spacer member 3. The cover member 4 is fixed to the side of the base member 2 by fasteners 42 (bolts in Figure 1). Note that the fasteners 42 are not used when it is not necessary to fix the cover member 4. The fixing member 5 protrudes outward from a hole 41 made in the cover member 4. A nut 53 is fastened to the shaft portion 51 of the fixing member 5 so as to be located where the inner surface of the cover member 4 and the shaft portion 51 of the fixing member 5 come into contact. By providing the nut 53 as described above, the strength of the cover member 4 near the hole 41 is improved, and the durability against the mass of the electrical equipment when the electrical equipment is fixed to the fixing base 1 can be further improved. In addition, by providing a hook on the top surface of the fixing base 1, it may be made easier to move the fixing base 1 using a rope or the like. Specifically, holes may be drilled through the spacer member 3 and the cover member 4, and the hook may be bolted in place (not shown).

[0020] 6. Specific Example of the Fixing Base 1 A further specific example of the fixing base 1 is shown in Figure 5. In Figure 5, parts numbered the same as in Figure 1 are described in the same way as in Figure 1 unless otherwise specified. In the example of the fixing base 1 in Figure 5, the concrete base members 2 have a length when viewed from the planar direction, and at least two (three in Figure 5) are arranged in parallel. The spacer members 3 are made of steel, have a length when viewed from the planar direction (H-beams in Figure 5), and are installed perpendicular to the length direction of the base members 2 (two in Figure 5). By adopting this configuration, the mass of the fixing base 1 can be made lighter, and the burden on workers when installing the fixing base 1 can be further reduced. In Figure 5, the three base members 2 are installed in parallel, but these base members 2 do not necessarily have to be installed in parallel, and their positional relationship can be adjusted as appropriate depending on the installation location. Furthermore, although the spacer member 3 is shown in Figure 5 spanning the base member 2 perpendicularly, this angle does not necessarily have to be perpendicular, and can be adjusted as appropriate depending on the installation location.

[0021] 7. Specific Example of the Fixing Base 1 A further specific example of the fixing base 1 is shown in Figure 6. In Figure 6, parts numbered the same as in Figures 1 and 5 are described in the same way as in Figures 1 and 5 unless otherwise specified. In the example of Figure 6, a base member 2 having a groove 21 and a latching part 22 is used as the base member 2 for fixing the fixing member 5 (the middle base member 2 shown in Figure 3(C)). The fixing member 5 (a bolt in Figure 6) has its head 52 housed in the groove 21 and is latched by the latching part 22. By screwing it in using a nut 54 from the opposite side of the head 52, the latching part 22 is sandwiched between the head 52 and the nut 54, and the fixing member 5 can be fixed to the base member 2 at the desired position in the groove 21. By using a base member 2 as described above, the position of the fixing member 5 can be adjusted on site according to the conditions of the place where the electrical equipment is to be installed. Furthermore, if the position of the fixing member 5 needs to be adjusted on-site, the position of the fixing member 5 can be determined first, and then a hole 41 can be drilled on-site at a location in the cover member 4 corresponding to the position of the fixing member 5. Also, in Figure 6, the spacer member 3 is fixed to the base member 2, which does not have a groove 21 and a hooking portion 22, using a fastener 31. However, the spacer member 3 may also be fixed to the base member 2, which includes a groove 21 and a hooking portion 22. In this case, for example, a hole can be drilled in a predetermined location on the spacer member 3, the head of the fastener 31 can be hooked onto the hooking portion 22, and the shaft can be passed through the hole in the spacer member 3 and bolted in place to secure it.

[0022] 8. Specific Example of the Fixing Base 1 A further specific example of the fixing base 1 is shown in Figure 7. In Figure 7, parts numbered the same as in Figures 1, 5, and 6 are described in the same way as in Figures 1, 5, and 6 unless otherwise specified. In the example of Figure 7, instead of a fixing member 5, a hole 23 is made in the base member 2. A fixing member fixing part 24 (a nut in the example of Figure 7) is embedded near the upper end of the hole 23. The center of the hole 23 in the base member 2 and the center of the hole 41 made in the cover member 4 overlap on line α (see Figures 7(B) and (C)). In the example of Figure 7, the fixing member 5 (for example, a bolt) can be inserted into the hole 23 through the hole 41 at the site and fixed using the fixing member fixing part 24 (a nut in the case of Figure 7) (screw fastening in the case of Figure 7).

[0023] 9. Fixing Electrical Equipment Using the Fixing Base 1 Figures 8 and 9 show a specific example of fixing electrical equipment EE using the fixing base 1 of the present invention. A hole is made in the bottom of the housing HO of the electrical equipment EE, and the shaft portion 51 of the fixing member 5 protruding from the cover member 4 is inserted into the hole and fastened with a nut 55 (see Figures 8 and 9(A)). At the installation site of the electrical equipment EE, for example, the bottom of the housing HO of the electrical equipment EE can be removed, fixed to the fixing base 1 by fastening the bottom with a nut 55, and then the housing HO can be reassembled to fix the electrical equipment EE to the fixing base 1. Furthermore, by making additional holes 41', 41' in the fixing base 1, the cable CA of the electrical equipment EE can be passed through the inside of the fixing base 1 to the outside. Inside the fixing base 1 of the present invention, at least a space surrounded by the cover member 4 around the spacer member 3 is secured, and the cable CA can be passed through this space. The cable CA is enclosed by the cover member 4 and can also be passed over the base member 2, eliminating the need for burial work and minimizing damage from animals, etc. When removing the electrical equipment EE, it can be easily removed by performing the reverse of the installation procedure. Because the fixing base 1 of the present invention has a simple structure, it is easy to attach and detach the electrical equipment.

[0024] Figure 9(B) shows the configuration when the electrical equipment EE is fixed using the fixing base 1 of Figure 7. In the example of Figure 9(B), the bottom of the housing HO is removed, as in the case of Figure 9(A), and the bottom of the housing HO is fixed to the fixing base 1 by fastening a fixing member fixing part 24 (nut in Figure 9(B)) embedded in the upper part of a hole 23 made in the base member 2 through a hole 41 in the cover member 4 and a hole drilled in the bottom of the HO, using a fixing member 5 (bolt in Figure 9(B)). After fixing the bottom of the housing HO to the fixing base 1, the housing HO is reassembled in the same way as in the case of Figure 9(A).

[0025] When there are multiple electrical devices to be installed on site (for example, EV chargers, power distribution equipment, and transformers installed in the same location), these multiple electrical devices can be fixed to a single fixing base 1 by increasing the area of ​​the fixing base 1 in the planar direction and increasing the number of fixing members 5 used. By fixing multiple electrical devices to a fixing base 1 with a large area in this way, when connecting individual electrical devices with cables, the cables can be connected through the internal space of the same fixing base 1, eliminating the need for cable burial work. Alternatively, a fixing base 1 can be prepared for each individual electrical device, and each electrical device can be fixed to its respective fixing base 1. In this case, by placing each fixing base 1 close together, the frequency with which the cables connecting each electrical device are exposed to the outside can be minimized. Furthermore, a fixing base 1 without any electrical devices installed can be used as a substitute for conduit for cables, etc.

[0026] Embodiments in which a fixed base has a portion considered to be a support column, and electrical equipment is fixed thereto by a fixing member, are also within the scope of the present invention. In other words, the portion of the electrical equipment or cover member is considered to be part of the electrical equipment or part of the cover member, and this claim confirms that it is within the scope of the present invention. Furthermore, even if the support column is considered to be a separate member, Claim 1 does not exclude the presence of a support column, and since the member is an open claim, it goes without saying that it is within the scope of the present invention.

[0027] Electrical equipment using the fixed base of the present invention, specifically vehicle charging devices, can be assembled in advance at a factory or the like, transported to the site, and installed. Furthermore, because its structure is not complex, the electrical equipment can be easily attached and detached, significantly reducing the amount of work required at the site where the electrical equipment is installed. This can greatly contribute to industries that require electrical equipment such as charging devices, such as the spread of electric vehicles (EVs). Specifically, the present invention is extremely useful whether the charging equipment is a fast-charging system, a medium-speed charging system, or a slow-speed charging system. The cables of the charging equipment are thicker than the cables of other general electrical equipment, making the present invention particularly useful in this respect. Moreover, the more cables there are, the greater the usefulness becomes. From this viewpoint, fast-charging systems with the thickest cables are preferred. Furthermore, the usefulness of the present invention increases as the number of charging devices installed on fixed bases such as 4, 5, 6, 7, 8, 10, and 12 increases, making it even more useful for fast, medium-speed, and slow-speed electrical equipment.
