Description

Technical Field

[0001] The invention relates to an assembling structure for assembling a first component to a second component. Background Art

[0002] Electronic devices exemplified in car navigation devices, car audio systems, etc., are configured such that a resin panel having a display unit and an operation unit is assembled to a main body having electronic components such as a drive circuit and a display panel housed inside a frame. In connection therewith, a structure is known in which a so-called "snap-on" snap-on mechanism is used to assemble the resin panel to the main body, and the so-called "snap-on" is a form of fixing by embedding using the elasticity of the material (e.g., Patent Document 1).

[0003] As an assembly structure using a snap-fit ​​mechanism, there are examples of a structure in which two components are fixed by a snap-fit ​​mechanism, a structure in which two components are temporarily fixed by a snap-fit ​​mechanism and then fixed by a fastening member such as a screw, etc. The snap-fit ​​mechanism is a means for fixing only two components, so in order to assemble the two components with high precision, an additional positioning mechanism is required. In the past, as a structure in which a resin panel is assembled to a main body using a snap-fit ​​part provided on the resin panel, there was a structure in which a pin provided on the resin panel other than the snap-fit ​​part was inserted into the main body to position the two components.

[0047] [Overall composition]

[0048] Figure 1 It is an overall perspective view of the assembly 100 according to the present embodiment. Figure 2 It is an exploded view of the assembly 100. The assembly 100 is a part of the vehicle-mounted device. The vehicle-mounted device is mounted on the vehicle and is used to provide general car navigation functions and audio functions. The vehicle-mounted device is a so-called built-in type and is buried in the vehicle's instrument panel or dashboard (neither of which are shown in the figure). The vehicle-mounted device is assembled by assembling a display unit (not shown) that displays various visual information and an operating unit (not shown) that accepts input operations performed by the user with respect to the assembly 100. The display unit is, for example, a liquid crystal panel. The operating unit is, for example, an operating button or a touch panel. It should be noted that in this specification, unless otherwise specified, the words "input" and "output" will be used interchangeably. Figure 1 The “front-rear direction”, “up-down direction”, and “left-right direction” shown in the figure are defined as the “front-rear direction”, “up-down direction”, and “left-right direction” of the assembly 100 .

[0049] like Figure 1 and Figure 2 As shown, the assembly 100 includes a panel-shaped resin panel 10 and a box-shaped main body 20. The resin panel 10 is a component in which the above-mentioned display unit and operating unit are assembled. The resin panel 10 is made of resin and is formed by injection molding using a mold. The main body 20 is a component that performs processing for exerting the function of the vehicle-mounted device. The main body 20 supplies various visual information to the display unit assembled on the resin panel 10. In addition, the operation information received by the operating unit assembled on the resin panel 10 is output to the main body 20. The assembly 100 is assembled by assembling the resin panel 10 on the front surface of the main body 20. The resin panel 10 is an example of the "first component" of the present invention, and the main body 20 is an example of the "second component" of the present invention. However, the "first component" and the "second component" of the present invention are not limited to this embodiment.

[0050] Figure 3 2 is an exploded view of the main body 20. Figure 2 and Figure 3 As shown, the main body 20 includes a metal assembly panel 2 and a frame 3. The frame 3 is a roughly rectangular box with an open front surface. Various hardware (not shown) such as a CPU (Central Processing Unit), a memory, a communication interface, and an input / output interface are built into the frame 3. The assembly panel 2 is arranged on the front surface of the main body 20. In more detail, the assembly panel 2 is a panel-shaped component, which is assembled on the front surface of the frame 3 to form the front surface of the main body 20. In the combination of the assembly 100, the resin panel 10 is assembled relative to the assembly panel 2 in a state where it has been assembled to the frame 3. The assembly panel 2 is equivalent to an example of the "second assembly part" of the present invention.

[0051] Figure 4 1 is a perspective view showing a state where the resin panel 10 is assembled to the assembly panel 2. Figure 4 The frame 3 is omitted in the figure. Figure 4 As shown, the resin panel 10 is provided with an assembly portion 1 as a structure for assembling to the assembly panel 2. The assembly portion 1 is an example of the "first assembly portion" of the present invention. The structure including the assembly portion 1 and the assembly panel 2 is equivalent to an example of the "assembly structure" of the present invention. The structure of the assembly portion 1 and the assembly panel 2 is described below.

[0052] [Assembly section 1]

[0053] Figure 5 2 is a rear view schematically showing the assembly unit 1. Figure 5 In FIG. 1 , the assembly portion 1 is shown in a simplified manner. Figure 6 yes Figure 5 AA section view. Figure 5 As shown, the assembly portion 1 includes a first panel 11 having a rectangular shape in a rear view (front view) and a peripheral wall portion 12 rising backward from the peripheral edge of the first panel 11. The peripheral edge of the first panel 11 includes an upper side 111, a lower side 112, and a pair of side sides 113, 114. The pair of side sides 113, 114 are orthogonal to the upper side 111 and the lower side 112. The peripheral wall portion 12 includes a first upper wall 121, a first lower wall 122, and a pair of first side walls 123, 124. The first upper wall 121 rises from the upper side 111, and the first lower wall 122 rises from the lower side 112. The pair of first side walls 123, 124 rise from the pair of side sides 113, 114, respectively. The first lower wall 122 is an example of the "first engaging wall" of the present invention, and the pair of first side walls 123, 124 are an example of the "first orthogonal engaging wall" of the present invention.

[0054] like Figure 5 and Figure 6As shown, the first upper wall 121 is provided with an upper wall rib 13 extending in the rising direction of the first upper wall 121. The upper wall rib 13 is a rib for imparting strength to the first upper wall 121 and is also used for positioning the resin panel 10 and the main body 20 described later.

[0055] In addition, if Figure 5 and Figure 6 As shown, the assembly portion 1 is provided with a base portion 14 , a locking portion 15 and a positioning hole 16 . Figure 7 1 is a three-dimensional view of the vicinity of the engaging portion 15. Figure 7 As shown, the base portion 14 is formed as a part of the first panel 11. The engaging portion 15 is a snap-fit ​​engaging mechanism formed as a part of the first lower wall 122. In addition, the engaging portion 15 includes an extension portion 151 and an engaging protrusion 152. The extension portion 151 rises from the base portion 14 and extends rearward. The engaging protrusion 152 is provided on the extension portion 151 and protrudes in a direction orthogonal to the extending direction of the extension portion 151. In this example, the engaging protrusion 152 protrudes upward.

[0056] Figure 7 The reference numeral CP1 in the figure shows the connection portion of the base portion 14 connected to the engaging portion 15. Figure 7 As shown, the positioning hole 16 is a hole formed around the connection portion CP1 of the base portion 14 connected to the engaging portion 15. In other words, the positioning hole 16 is formed at the root of the engaging portion 15 at the base portion 14. Here, Figure 8 1 is a diagram for explaining the positional relationship between the positioning hole 16 and the engaging protrusion 152. Figure 8 The middle figure shows a state of visual recognition along the extending direction of the extending portion 151 . Figure 8 The reference numeral P1 shows an imaginary plane perpendicular to the extension direction (in this example, the front-rear direction) of the extension portion 151. In addition, the reference numeral A1 shows the area after the positioning hole 16 is projected onto the plane P1. In addition, the reference numeral A2 shows the area after the engagement protrusion 152 is projected onto the plane P1. Figure 8 As shown, the projection area A2 of the engagement protrusion 152 is entirely included in the projection area A1 of the positioning hole 16 .

[0057] in addition, Fig. 9 It is a cross-sectional view schematically showing a mold when the resin panel 10 is molded by injection molding. Fig. 9 The reference numeral C1 indicates a concave mold, and the reference numeral C2 indicates a convex mold. The resin panel 10 of this example is injection molded using a mold that is pulled out in both the front and rear directions. Fig. 9 As shown in FIG. 1 , in order to form the engaging portion 15, it is necessary to form an engaging protrusion 152 protruding in a direction perpendicular to the extraction direction of the mold. In other words, the engaging portion 15 is formed into a so-called concave cut shape. Fig. 9 As shown, the engaging portion 15 is formed by a so-called pliers structure in which a part of the punch C2 is made to protrude toward the die C1 side. The engaging protrusion 152 is formed by the protrusion C21 of the punch C2 protruding toward the die C1 side. At this time, a positioning hole 16 is formed in the base portion 14 as a through hole for pulling out the protrusion C21 when demolding. Therefore, the positioning hole 16 is formed in such a manner that the projection area A2 of the engaging protrusion 152 is entirely included in the projection area A1 of the positioning hole 16 as described above. Thus, the positioning hole 16 is formed at a position opposite to the engaging protrusion 152 in the root of the extension portion 151 at the base portion 14. In addition, the positioning hole 16 is a through hole for forming the engaging portion 15, and is therefore formed as a through hole. As shown in FIG. Figure 2 As shown, the positioning hole 16 penetrates the resin panel 10 and opens at the front surface of the resin panel 10. The positioning hole 16 is an example of the "hole" in the present invention.

[0058] like Figure 5 and Figure 6 As shown, a side wall snap-fitting portion 17a in the form of a snap and a side wall rib 18a extending in the rising direction of the first side wall 123 are provided in parallel on the first side wall 123. The side wall snap-fitting portion 17a is formed as a part of the first side wall 123. In addition, the side wall rib 18a is a rib for imparting strength to the first side wall 123, and is also used for positioning the resin panel 10 and the main body 20 described later. Similarly, a side wall snap-fitting portion 17b in the form of a snap-fitting portion and a side wall rib 18b extending in the rising direction of the first side wall 124 are provided in parallel on the first side wall 124. The side wall snap-fitting portion 17b is formed as a part of the first side wall 124. In addition, the side wall rib 18b is a rib for imparting strength to the first side wall 124, and is also used for positioning the resin panel 10 and the main body 20 described later. The side wall ribs 18a and 18b are examples of "ribs" of the present invention.

[0059] [Assembly panel 2]

[0060] Fig.10 2 is a schematic diagram showing a front view of an assembled panel 2. Fig.10 The assembly panel 2 is shown in a simplified manner. Fig.11 for Fig.10 BB cross-sectional view. Fig.10As shown, the assembly panel 2 includes a second panel 21 that is rectangular in front view. The periphery of the second panel 21 includes an upper side 211, a lower side 212, and a pair of side sides 213, 214. The pair of side sides 213, 214 are orthogonal to the upper side 211 and the lower side 212. In addition, the assembly panel 2 includes a second upper wall 221, a second lower wall 222, and a pair of second side walls 223, 224. The second upper wall 221 stands from the upper side 211, and the second lower wall 222 stands from the lower side 212. The pair of second side walls 223, 224 each stands from a pair of side sides 213, 214. The second lower wall 222 is an example of a "second engaging wall" of the present invention, and the pair of second side walls 223, 224 is an example of a "second orthogonal engaging wall" of the present invention.

[0061] like Fig.10 and Fig.11 As shown, the second upper wall 221 is provided with an upper wall positioning groove 23 extending along the rising direction of the second upper wall 221. The upper wall positioning groove 23 is a groove capable of accommodating the upper wall rib 13 of the assembly part 1.

[0062] In addition, if Fig.10 and Fig.11 As shown, an insertion portion 24 is provided on the second lower wall 222 of the assembly panel 2 . Fig.12 FIG. 2 is a three-dimensional diagram of the vicinity of the insertion portion 24. Fig.12 As shown, the insertion portion 24 is formed as a part of the second lower wall 222 and extends forward from the second panel 21. In addition, the insertion portion 24 includes a locking portion 25 and a positioning protrusion 26. The locking portion 25 is formed as an inner wall of a hole provided at the base end of the insertion portion 24, and is engaged with the locking protrusion 152 of the locking portion 15 of the assembly portion 1 to lock the locking portion 15. The positioning protrusion 26 is a protrusion formed as the top end (front end) of the insertion portion 24, and can be inserted into the positioning hole 16 of the assembly portion 1. The positioning protrusion 26 is an example of a "protrusion" in the present invention.

[0063] like Fig.10 and Fig.11As shown, the second side wall 223 is provided with a side wall stopper 27a and a side wall groove 28a. The side wall stopper 27a is formed as the inner wall of the hole provided in the second side wall 223, and is engaged with the side wall engagement portion 17a of the assembly portion 1 to lock the side wall engagement portion 17a. The side wall groove 28a is a groove extending along the rising direction of the second side wall 223, and can accommodate the side wall rib 18a of the assembly portion 1. Similarly, the second side wall 224 is provided with a side wall stopper 27b and a side wall groove 28b. The side wall stopper 27b is formed as the inner wall of the hole provided in the second side wall 224, and is engaged with the side wall engagement portion 17b of the assembly portion 1 to lock the side wall engagement portion 17b. The side wall groove 28b is a groove extending along the rising direction of the second side wall 224, and can accommodate the side wall rib 18b of the assembly portion 1. The side wall grooves 28a and 28b are examples of the "grooves" of the present invention.

[0064] [Assembly method]

[0065] Fig.13 FIG. 2 is a rear view schematically showing the state of the assembly portion 1 and the assembly panel 2 in the assembly 100. Fig.13 In the figure, the assembly portion 1 and the assembly panel 2 are shown in a simplified manner. Fig.14 for Fig.13 Hereinafter, a method for assembling the resin panel 10 with respect to the main body 20 will be described.

[0066] pass Fig.13 and Fig.14The assembly part 1 and the assembly panel 2 are connected as shown, so that the resin panel 10 is assembled to the main body 20. Specifically, the following state is formed: the positioning protrusion 26 of the assembly panel 2 is inserted into the positioning hole 16 of the assembly part 1, the upper wall rib 13 of the assembly part 1 is accommodated in the upper wall positioning groove 23 of the assembly panel 2, and the side wall ribs 18a and 18b of the assembly part 1 are accommodated in the side wall grooves 28a and 28b of the assembly panel 2. In addition, the engaging portion 15 of the assembly part 1 is engaged with the locking portion 25 of the assembly panel 2, and the side wall engaging portions 17a and 17b of the assembly part 1 are engaged with the side wall locking portions 27a and 27b of the assembly panel 2. By inserting the positioning protrusion 26 of the assembly panel 2 into the positioning hole 16 of the assembly part 1 and accommodating the upper wall rib 13 of the assembly part 1 into the upper wall positioning groove 23 of the assembly panel 2, the movement of the resin panel 10 in the left and right direction relative to the main body 20 is restricted. Thus, the resin panel 10 and the main body 20 are positioned in the left-right direction. In addition, by accommodating the side wall ribs 18a, 18b of the assembly part 1 in the side wall grooves 28a, 28b of the assembly panel 2, the vertical movement of the resin panel 10 relative to the main body 20 is restricted. Thus, the resin panel 10 and the main body 20 are positioned in the vertical direction. Furthermore, by engaging the engaging portion 15 of the assembly part 1 with the locking portion 25 of the assembly panel 2, and engaging the side wall engaging portions 17a, 17b of the assembly part 1 with the side wall locking portions 27a, 27b of the assembly panel 2, the resin panel 10 is fixed relative to the main body 20. These components can also be set to a temporarily fixed state and then fixed using fastening components such as screws.

[0067] Here, Figure 15 to Figure 17 1 is a cross-sectional view showing the process of assembling the resin panel 10 to the main body 20. In order to connect the assembly part 1 and the assembly panel 2, first, as shown in FIG. Fig.15 As shown in FIG. 1 , the resin panel 10 is arranged in front of the main body 20. Next, Fig.15 From the state shown, the resin panel 10 is moved toward the main body 20 side (rearward). At this time, the resin panel 10 is moved in a state where the resin panel 10 is aligned relative to the main body 20 in such a manner that the positioning protrusion 26 of the assembly panel 2 can be inserted into the positioning hole 16 of the assembly part 1. As described above, the positioning hole 16 is formed at a position on the base part 14 opposite to the engaging protrusion 152. Therefore, as Fig.16 As shown, before the positioning protrusion 26 is inserted into the positioning hole 16, the engaging protrusion 152 abuts against the positioning protrusion 26. In this state, when the resin panel 10 is further moved toward the main body 20 side against the elastic force of the engaging portion 15, as shown in FIG. Fig.17 As shown in FIG. 1 , the positioning protrusion 26 straddles the engaging protrusion 152. In this state, when the resin panel 10 is further moved toward the main body 20, as shown in FIG. Fig.14 As shown, the positioning protrusion 26 is inserted into the positioning hole 16 .

[0068] like Figure 15 to Figure 17 As shown in the figure, the insertion part 24 provided with the positioning protrusion 26 and the stopper 25 extends along the insertion direction (the front direction in this example) of the positioning protrusion 26 relative to the positioning hole 16. In addition, in the insertion direction, the stopper 25 is located closer to the front side than the positioning protrusion 26. Therefore, when the insertion part 24 is moved along the insertion direction, the positioning protrusion 26 crosses the engaging protrusion 152 and is inserted into the positioning hole 16, whereby the engaging protrusion 152 is engaged with the stopper 25.

[0069] In addition, if Figure 1 As shown, in a state where the resin panel 10 is assembled to the main body 20 to form the assembly 100, the positioning protrusion 26 protrudes from the positioning hole 16 on the front surface of the resin panel 10. As described above, the positioning hole 16 is a through hole that penetrates the resin panel 10 from front to back. Therefore, when the operator assembles the resin panel 10 to the main body 20, the operator can visually recognize the positioning protrusion 26 of the assembly panel 2 through the positioning hole 16 from the front surface side of the resin panel 10, and align the positioning hole 16 with the positioning protrusion 26.

[0070] [Function and Effect]

[0071] As described above, the assembly structure of the present embodiment includes an assembly portion 1 provided on the resin panel 10 and an assembly panel 2 provided on the main body 20. The assembly portion 1 includes a base portion 14, a snap-fitting engaging portion 15 extending upward from the base portion 14, and a positioning hole 16 formed around a connection portion CP1 of the base portion 14 connected to the snap-fitting portion 15. The assembly panel 2 includes a stopper 25 that stops the snap-fitting portion 15 by engaging with the snap-fitting portion 15, and a positioning protrusion 26 that can be inserted into the positioning hole 16. When the positioning protrusion 26 is inserted into the positioning hole 16, the snap-fitting portion 15 is engaged with the stopper 25.

[0072] In the assembly structure of the present embodiment, the positioning hole 16 that can be used for positioning the resin panel 10 and the main body 20 is formed at the root (around the connection part CP1) of the engaging part 15 for fixing the resin panel 10 and the main body 20. In other words, the positioning mechanism and the engaging mechanism are arranged at the same position. Thus, according to the assembly structure of the present embodiment, compared with the case where the positioning mechanism and the engaging mechanism are arranged at different positions, the space required for setting these mechanisms can be reduced. In other words, space saving can be achieved. As a result, it contributes to the miniaturization of the product.

[0073] In addition, the engaging portion 15 of the present embodiment includes: an extension portion 151 extending upward from the base portion 14; and an engaging protrusion 152 provided on the extension portion 151 and protruding in a direction orthogonal to the extending direction of the extension portion 151, for engaging with the stopper 25. In addition, the positioning hole 16 is formed in such a manner that the projection area A2 of the engaging protrusion 152 is entirely included in the projection area A1 of the positioning hole 16 when the engaging protrusion 152 and the positioning hole 16 are projected on a plane P1 orthogonal to the extending direction of the extension portion 151. In addition, the stopper 25 and the positioning protrusion 26 are provided on the insertion portion 24 extending along the insertion direction of the positioning protrusion 26 relative to the positioning hole 16. And, in the insertion direction, the stopper 25 is located closer to the front side than the positioning protrusion 26. Thus, when the insertion portion 24 is moved along the insertion direction in order to insert the positioning protrusion 26 into the positioning hole 16, the engaging protrusion 152 engages with the stopper 25. Thus, the engaging protrusion 152 can be engaged with the locking portion 25 by a single operation of inserting the positioning protrusion 26 into the positioning hole 16. As a result, the workability of assembly can be improved.

[0074] In addition, in the present embodiment, the resin panel 10 is made of resin, and the positioning hole 16 is a through hole formed in the base portion 14 in order to form the engaging portion 15 using a mold. Thus, the through hole during forming is used as a positioning mechanism, thereby reducing the required space compared to the case where a positioning mechanism is provided separately. It should be noted that, although the entire resin panel 10 is made of resin in this example, the entire first component of the present invention may not be made of resin. It is also possible that only the first assembly portion provided in the first component is made of resin. In addition, the positioning hole of the present invention may not be a through hole.

[0075] In addition, the assembly portion 1 of the present embodiment includes a first panel 11 having a rectangular shape in front view, a first lower wall 122 rising from the lower side 112 of the first panel 11, and a pair of first side walls 123, 124 rising from a pair of side sides 113, 114 perpendicular to the lower side 112. In addition, the assembly panel 2 includes a second panel 21 having a rectangular shape in front view, a second lower wall 222 rising from the lower side 212 of the second panel, and a pair of second side walls 223, 224 rising from a pair of side sides 213, 214 perpendicular to the lower side 212. In addition, the base portion 14 is formed as a part of the first panel 11, and the engaging portion 15 is formed as a part of the first lower wall 122. In addition, the locking portion 25 and the positioning protrusion 26 are formed as a part of the second lower wall 222. In addition, the pair of first side walls 123, 124 are respectively provided with side wall ribs 18a, 18b extending in the rising direction of the pair of first side walls 123, 124. Furthermore, a pair of second side walls 223, 224 are respectively provided with side wall grooves 28a, 28b capable of accommodating the side wall ribs 18a, 18b. Therefore, the side wall ribs 18a, 18b and the side wall grooves 28a, 28b can be used for positioning. Thus, by configuring the positioning mechanism on the lower side 112 as one side of the first panel 11 and a pair of side sides 113, 114 orthogonal to the lower side 112, the resin panel 10 can be assembled with high precision relative to the main body 20. In addition, by providing the side wall engaging parts 17a, 17b as the engaging mechanism and the side wall ribs 18a, 18b as the positioning mechanism, space saving can be achieved. It should be noted that, although the engaging mechanism and the positioning mechanism are configured on the lower side 112 and the pair of side sides 113, 114 of the first panel 11 in this example, the present invention is not limited thereto. In other words, the side of the panel where the engaging mechanism and the positioning mechanism are configured is not particularly limited.

[0076] In addition, the positioning hole 16 of the present embodiment is formed as a through hole that passes through the resin panel 10. Therefore, when the operator assembles the resin panel 10 to the main body 20, the operator can visually identify the positioning protrusion 26 of the assembly panel 2 through the positioning hole 16 from the front surface side of the resin panel 10, in other words, from the side opposite to the main body 20 across the resin panel 10, and align the positioning hole 16 with the positioning protrusion 26. Therefore, the operator can confirm whether the positioning is correct by visual observation. As a result, the assembly of the resin panel 10 relative to the main body 20 becomes easy. As a result, the workability of the assembly can be improved. It should be noted that the positioning hole of the present invention may not be a through hole.
