Description

[0001] The present invention relates to a method for assembling a loudspeaker enclosure in a motor vehicle component, wherein the motor vehicle component has an outer wall, an inner wall with a sound hole opening, and a space formed between the outer wall and the inner wall. Furthermore, the present invention relates to a loudspeaker enclosure, in particular a bass box, suitable for a method according to the invention, as well as to a motor vehicle component comprising a loudspeaker enclosure.

[0002] A large number of loudspeakers are installed in motor vehicles. Loudspeaker cabinets are also used to influence the reproduction characteristics and / or the power handling of the sound transducers. In particular, to optimize the reproduction of low frequencies, such loudspeaker cabinets are also designed as bass boxes. Loudspeaker cabinets are installed, among other things, in vehicle doors, such as side doors or sliding doors, and can be mounted in particular between an outer wall, in particular an outer panel, and an inner wall, in particular an inner panel, of the vehicle door. Precise positioning of the loudspeaker cabinet or the bass box is crucial. In this case, the use of auxiliary geometries on the vehicle component is usually not possible. In addition, the loudspeaker cabinet should have the largest possible volume, which is why additional auxiliary geometries are disadvantageous.

[0003] Due to the often difficult accessibility of the space between the outer and inner walls of the vehicle component, the fastening of a loudspeaker cabinet cannot usually be carried out by a worker alone.

[0004] From KR 2001-0066476 A1 a loudspeaker device for a motor vehicle door is known, comprising a protective device which accommodates a loudspeaker and is attached to an inner panel of the door.

[0005] KR 100948132 B1 discloses a locking device comprising a housing body forming an external appearance and a skeleton, and which is provided with a block fastening portion. The block fastening portion is configured to penetrate through a fastening hole.

[0006] DE 10 2005 026 016 A1 discloses that a loudspeaker membrane mount is positively attached to a separate bracket. The membrane mount includes locking hooks that engage in a locking opening in the bracket. The bracket is, for example, part of a vehicle door.

[0007] DE 101 96 314 B4 shows that a loudspeaker frame of a loudspeaker is attached to an inner panel of an automobile door by engaging a snap-in part of the loudspeaker frame with a mounting hole in the inner panel. The loudspeaker is mounted from the passenger compartment side.

[0008] The present invention is based on the object of providing a method for assembling a loudspeaker housing, in particular a bass box, in a motor vehicle component, which method can be carried out easily and safely by a worker alone and with which, moreover, the installation space available for the loudspeaker housing is not unnecessarily reduced.

[0009] To achieve the object underlying the invention, a method for mounting a loudspeaker housing in a motor vehicle component is proposed, wherein the motor vehicle component has an outer wall, an inner wall with a sound hole opening, and an intermediate space formed between the outer wall and the inner wall, wherein a loudspeaker housing comprising at least one locking device is inserted into the intermediate space, wherein the locking device is inserted and locked into a hole in the inner wall in such a way that the loudspeaker housing is held securely in position on the inner wall in an installed position.

[0010] A sound hole is, in particular, a hole in the interior wall through which sound waves can enter or exit the loudspeaker cabinet. Such sound holes are provided by the manufacturer in corresponding automotive components.

[0011] The motor vehicle component has an inner wall and an outer wall. When mounted on the motor vehicle, the outer wall is the wall located on the outside of the vehicle, and the inner wall is the wall located on the inside of the vehicle. A gap is formed between the outer and inner walls, which is intended for the placement of the loudspeaker housing.

[0012] The outer wall and / or the inner wall can be made of metal or plastic. Especially if the outer wall and / or the inner wall are made of metal, they can also be referred to as outer sheet and / or inner sheet.

[0013] The loudspeaker enclosure has at least one locking device. The locking device serves to securely mount the loudspeaker enclosure to the interior wall. A secure mounting of the loudspeaker enclosure is defined as a mounting that is sufficient to hold the loudspeaker enclosure securely during subsequent assembly steps and, if necessary, also sufficient to continue to hold the loudspeaker enclosure securely to the interior wall later in the vehicle's life.

[0014] The inner wall also has a hole. The hole in the inner wall is preferably provided in a region of the inner wall that borders the sound hole opening. The hole is preferably located close to, in particular at a distance of less than 3 cm from, the sound hole opening.

[0015] In addition, several holes and correspondingly several locking devices can be provided.

[0016] The locking device is arranged on the loudspeaker housing in such a way that the locking device can be arranged at or on the hole when the loudspeaker housing is inserted into the space, inserted into the hole and locked into the hole.

[0017] By using a snap-in device, additional auxiliary geometries on the automotive component, especially on the outer and / or inner walls, are eliminated. Snap-in connections are easy for a single worker to create, allowing the loudspeaker enclosure to be attached to the automotive component by a single worker at different times during the production process.

[0018] By omitting auxiliary geometries, the available installation space for the loudspeaker cabinet can also be maximized.

[0019] It is preferably provided that the loudspeaker housing is a bass box and / or that the motor vehicle component is a vehicle door, in particular a side door or a sliding door, for a motor vehicle.

[0020] Especially with sliding doors, the available space between the outer and inner walls is usually very small. For this reason, the method according to the invention is particularly suitable for mounting a loudspeaker cabinet on a sliding door of a motor vehicle.

[0021] Another advantage is that a loudspeaker is attached to the sound hole opening.

[0022] The loudspeaker is preferably attached to the sound hole opening using screws and only after the loudspeaker cabinet has been securely held in position on the inner wall by means of the locking device in the installed position.

[0023] It is further provided that the loudspeaker is attached to a side of the inner wall opposite the loudspeaker housing. The loudspeaker is preferably attached above the sound hole opening. By attaching the loudspeaker to a side of the inner wall opposite the loudspeaker housing, the loudspeaker is in particular not arranged in the loudspeaker housing and, moreover, in particular not in the space between the outer and inner walls of the motor vehicle component. This simplifies assembly, and secondly, the space available for the loudspeaker housing between the outer and inner walls in the motor vehicle component is not unnecessarily reduced.

[0024] It is advantageously provided that the locking device has a hook with an undercut, wherein the hook is inserted into the hole in such a way that a first partial region of an edge region of the hole is inserted into the undercut, wherein preferably in the installed position the first partial region of the edge region of the hole is arranged in the undercut.

[0025] In other words, the locking device of the loudspeaker enclosure comprises a hook protruding from an outer wall of the loudspeaker enclosure. When the loudspeaker enclosure is inserted into the gap, this hook can be positioned opposite the hole in the inner wall and inserted into the hole. Through a further assembly movement, which is preferably directed vertically downward, the hook can engage over a portion of an edge of the hole, so that this portion of the edge of the hole is inserted into the undercut of the hook.

[0026] Alternatively or additionally, the loudspeaker housing can also have a locking device which is designed as a Christmas tree clip or comprises a pressure clip.

[0027] It is further advantageous that an end section of the hook is directed downwards in the installed position.

[0028] If the end section of the hook is facing downwards in the installed position, the part of the edge of the hole is inserted from below into the undercut of the hook. This holds the loudspeaker cabinet to the hole and thus to the inner wall due to the force of gravity. For installation, this means that the loudspeaker cabinet is inserted into the gap, the hook is positioned opposite the hole on the inner wall, and is inserted into the hole in the inner wall. The loudspeaker cabinet, including the hook, is then moved vertically downwards in one assembly movement so that the part of the edge of the hole engages in the undercut of the hook.

[0029] Furthermore, it can preferably be provided that the hook has an insertion bevel, wherein the insertion bevel is preferably formed on a side surface of the hook facing the loudspeaker housing, more preferably the end section of the hook.

[0030] As soon as the hook is inserted into the hole and moved, preferably vertically downward, such that a portion of the hole's edge is engaged by the hook, the portion of the hole's edge comes into contact with the insertion bevel. As the assembly movement continues, the portion of the hole's edge is guided along the insertion bevel, thus pulling the loudspeaker cabinet toward the interior wall.

[0031] Due to the insertion bevel, the height of the undercut also decreases, which may lead to jamming of the first part of the edge area of ​​the hole behind the undercut.

[0032] It can be further advantageously provided that the end section of the hook has a thickness of less than 2.0 mm, preferably less than 1.5 mm, particularly preferably less than 1.0 mm, and / or that in the installed position a side surface of the hook facing away from the loudspeaker housing, in particular of the end section of the hook, has a distance from the inner wall of less than 2.0 mm, preferably less than 1.5 mm, particularly preferably less than 1.0 mm.

[0033] Particularly when a loudspeaker is mounted on the side of the interior wall facing away from the loudspeaker cabinet, the locking device, and in particular the locking device hook, must not be very high to avoid affecting the sealing surface for the loudspeaker. Furthermore, the locking device, especially the hook, should preferably be low in height to avoid unnecessarily reducing the available installation space for the loudspeaker cabinet.

[0034] It is particularly preferably provided that the locking device comprises a fixing element, in particular a fixing projection, further in particular a fixing pin, wherein the fixing element in the installed position projects into the hole and / or is arranged in the hole, wherein the fixing element in the installed position bears against a second partial region of the edge region of the hole, preferably radially opposite the first partial region, and / or is tilted against the second partial region of the edge region of the hole.

[0035] If the locking device has a hook, the fixing element is arranged on the loudspeaker housing with respect to the hook in such a way that the fixing element can also be received in the hole when the first partial area of ​​the edge area of ​​the hole is completely encompassed by the undercut of the hook. During the implementation of the method for assembling the loudspeaker housing, the hook of the locking device is first arranged opposite the hole in the inner wall and inserted into the hole in such a way that the first partial area of ​​the edge area of ​​the hole can engage in the undercut of the hook. In this case, the fixing element is still in contact with the edge area of ​​the hole on the inside. During the preferably vertical assembly movement, the first partial area of ​​the edge area penetrates further into the undercut.As soon as the hook has completely encompassed the first part of the edge area of ​​the hole, the fixing element can also penetrate into the hole.

[0036] If the hook has a chamfered insertion, the loudspeaker cabinet is pulled closer to the interior wall during the vertical installation movement. Since, at least initially, the fixing element still rests against the edge of the hole, this can lead to forces that can cause slight deformation of the loudspeaker cabinet in the area where the locking device is located. This deformation is reversed as soon as the fixing element is inserted into the hole. The fixing element is essentially pressed into the loudspeaker cabinet. Once installed, the fixing element returns to its original position. This ensures that the hooks are firmly in place and the loudspeaker cabinet cannot move from its installed position.

[0037] Furthermore, an additional locking effect can be achieved. The fixing element rests against a second portion of the hole's edge region, preferably radially opposite the first portion of the hole's edge region. This means that a movement of the loudspeaker cabinet opposite to the assembly movement is no longer possible, since during such a movement, the fixing element rests against or strikes the second portion of the hole's edge region.

[0038] Furthermore, a loudspeaker housing, in particular a bass box, is designed to carry out a method described above, wherein the loudspeaker housing has a locking device.

[0039] The advantages, features and embodiments explained above with regard to the method can also be transferred analogously to the loudspeaker housing.

[0040] Thus, it can preferably be provided that the locking device comprises a hook and more preferably a fixing element.

[0041] A further solution to the problem underlying the invention consists in a motor vehicle component, in particular a vehicle door, comprising a loudspeaker housing as described above, wherein the loudspeaker housing has been fastened to an inner wall of the motor vehicle component using a method as described above.

[0042] It is preferably provided that the motor vehicle component is a vehicle door, in particular a side door or a sliding door, for a motor vehicle.

[0043] The invention is explained in more detail below with reference to the accompanying figures. They show: Fig. 1 a first perspective sectional view of a motor vehicle component with a loudspeaker housing, Fig. 2 a second perspective sectional view of a motor vehicle component with a loudspeaker housing, Fig. 3 a sound hole opening in an inner wall of a motor vehicle component, Fig. 4 a perspective view of a locking device on a loudspeaker cabinet, Fig. 5 a side view of a locking device on a loudspeaker cabinet, Fig. 6a is a plan view of a locking device arranged on a hole in an inner wall of a motor vehicle part, Fig. 6b a side view of a locking device arranged on a hole in an inner wall of a motor vehicle part, Fig. 7a is a plan view of a locking device inserted into a hole in an inner wall of a motor vehicle part, Fig. 7b a side view of a locking device inserted into a hole in an inner wall of a motor vehicle part, Fig. 8a is a plan view of a locking device arranged in a hole in an inner wall of a motor vehicle part in an installed position, Fig. 8b a side view of a locking device arranged in a hole in an inner wall of a motor vehicle part in an installed position, Fig. 9a a perspective view of a locking device designed as a Christmas tree clip, Fig. 9b a side view of a locking device designed as a Christmas tree clip, Fig. 10a a perspective view of a locking device with pressure clips, Fig. 10b a side view of a locking device with pressure clips, and Fig. 11 a flow diagram of a method for assembling a loudspeaker housing in a motor vehicle component.

[0044] To explain a method 100 for assembling a loudspeaker cabinet 10 in accordance with the invention, Fig. 1 is a perspective sectional view of a motor vehicle component 11. Fig. Figure 2 shows a further perspective sectional view. The motor vehicle component 11 is designed as a sliding door 12 for a motor vehicle. The motor vehicle component 11 has an outer wall 13 and an inner wall 14. The inner wall 14 is further provided with a sound hole opening 15 ( Fig. 2 and Fig. 3). A gap 16 is formed between the outer wall 13 and the inner wall 14. A loudspeaker enclosure 10, designed as a bass cabinet 17, is inserted into the gap 16. The loudspeaker enclosure 10 is held securely in position on the inner wall 14 in the illustrated installation position by means of a locking device 18.

[0045] Fig. Figure 3 shows a plan view of the inner wall 14. The inner wall 14 has a sound hole opening 15. In an edge region 19 of the sound hole opening 15, at least two holes 20 are arranged, each of which cooperates with a locking device 18, as explained below. Returning to Fig. 1, a loudspeaker 21 is attached to a side of the inner wall 14 facing away from the loudspeaker housing 10.

[0046] Fig. 4 and Fig. 5 show a perspective view and a side view of a region of the outer side 22 of the loudspeaker housing 10. The locking device 18 is arranged on the outer side 22 of the loudspeaker housing 10. The locking device 18 comprises a hook 23 and a fixing element 24 in the form of a fixing projection 25. The hook 23 has an end section 26, such that an undercut 27 is formed between the end section 26 of the hook and the outer side 22 of the loudspeaker housing 10. The hook 23, and in particular the end section 26 of the hook 23, further has an insertion bevel 28.

[0047] For the assembly of the loudspeaker housing 10, this is first introduced into the space 16 between the outer wall 13 and the inner wall 14 in a first process step until the locking device 18 and in particular the hook 23 of the locking device 18, as shown in the top view of the Fig. 6a and the side view of the Fig. 6b, is arranged opposite the hole 20 in the inner wall 14. In a second method step, the hook 23 is at least partially inserted into the hole 20. This is shown in the Fig. 7a and Fig. 7b. The loudspeaker cabinet 10 is then moved downwards in a vertical assembly movement. Fig. 8a and Fig. 8b, a first portion 29 of an edge portion 30 of the hole 20 is inserted into the undercut 27. As the assembly movement continues, the loudspeaker housing 10 is thereby pulled closer to the inner wall 14 of the motor vehicle component 11, and the fixing element 24, which was previously Fig. 7a and Fig. 7b, which was still in contact with a second partial region 31 of the edge region 30 of the hole 20, which is radially opposite the first partial region 29, is also inserted into the hole 20. Due to the insertion bevel 28, forces can act on the hook 23 and on the fixing element 24, which cause a temporary deformation of the outer side 22 of the loudspeaker housing 10. The fixing element 24 is virtually pressed into the loudspeaker housing 10. In the Fig. 8a and Fig. 8b, the fixing element 24 returns to its original position. In the installed position, the fixing element 24 thus rests on the inside of the second partial area 31 of the edge area 30 of the hole 20. This prevents a movement of the loudspeaker housing 10 that is opposite to the assembly movement, so that the loudspeaker housing 10 is securely held on the inner wall 14. After the secure mounting of the loudspeaker housing 10 on the inner wall 24 of the motor vehicle component 11, the loudspeaker 21 can then be removed, as shown in Fig. 1 and Fig. 2, are fastened by screwing on the side of the inner wall 14 facing away from the loudspeaker housing 10.

[0048] In the Fig. 9a to 10b alternative locking devices 18 are shown. Thus, the locking device 18 can be Fig. 9a and Fig. 9b may be designed as a Christmas tree clip 32. According to the Fig. 10a and Fig. 10b, the locking device 18 can also be realized by pressure clips 33.

[0049] Fig. 11 shows a flow diagram of a method 100 for assembling a loudspeaker housing 10 in a motor vehicle component 11. In a first method step S1, a loudspeaker housing 10 with at least one locking device 18 is inserted into a space 16 between an outer wall 13 and an inner wall 14 of a motor vehicle component 11. In a second method step S2, the locking device 18 is inserted into a hole 20 in the inner wall 14 and locked in place such that the loudspeaker housing 10 is held securely in an installed position on the inner wall 14 in a third method step S3.
