Description

[Technical Field]

[0001] The disclosed embodiments relate to an in-vehicle device, an attachment mechanism for the in-vehicle device, and an attachment method for the in-vehicle device. [Background technology]

[0002] There is a drive recorder in which a mounting part attached to the window glass of a vehicle and a camera that captures the surroundings of the vehicle are connected by a ball joint (see, for example, Patent Document 1). Ball joints are also used in on-board devices other than drive recorders, such as on-board radar.

[0003] When adjusting the angle of an in-vehicle device that uses a ball joint, the fixing screw that secures the connection between the joint ball on the in-vehicle device side and the ball receiving part on the mounting part side is loosened, the angle of the in-vehicle device is adjusted, and then the fixing screw is tightened to complete the angle adjustment. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-107474 Summary of the Invention [Problem to be solved by the invention]

[0005] However, vehicle-mounted devices that use ball joints require enough space between the window glass and the device to allow a hand to reach in and operate the fixing screws, so if the mounting parts support the vehicle-mounted device from diagonally above, the vehicle-mounted device is likely to be in the driver's field of vision.

[0006] One aspect of the embodiment has been made in consideration of the above, and aims to provide an in-vehicle device, an installation mechanism for the in-vehicle device, and an installation method for the in-vehicle device that can make it difficult for an attachment part attached to a window glass to be seen by the driver. [Means for solving the problem]

[0007] According to one embodiment, the vehicle-mounted device includes an attachment part, a vehicle-mounted device main body, and a fixing part. The attachment part has an attachment part attached to a vehicle window glass and a rod-shaped hanging part extending along the backside of the attachment surface of the attachment part and from which the vehicle-mounted device main body is suspended. The vehicle-mounted device main body has a semi-cylindrical first abutment part that abuts against at least a portion of the outer circumferential surface of the hanging part. The fixing part has a semi-cylindrical second abutment part that abuts against at least a portion of the outer circumferential surface of the hanging part, and is hook-fitted to the vehicle-mounted device main body with the hanging part sandwiched between the first abutment part and the second abutment part, thereby fixing the vehicle-mounted device main body to the attachment part. [Effects of the Invention]

[0008] In the vehicle-mounted device, the mounting mechanism for the vehicle-mounted device, and the mounting method for the vehicle-mounted device according to one aspect of the embodiment, the vehicle-mounted device body is fixed to the mounting part by a claw engagement between the vehicle-mounted device body and the fixing part, so no space is required between the window glass and the vehicle-mounted device to insert a hand to operate it.

[0009] Therefore, the vehicle-mounted device, the mounting mechanism for the vehicle-mounted device, and the mounting method for the vehicle-mounted device according to one aspect of the embodiment can shorten the distance from the window glass to the vehicle-mounted device, thereby making it less likely for the vehicle-mounted device to be in the driver's field of vision.

[0011] Hereinafter, embodiments of an in-vehicle device, an attachment mechanism for the in-vehicle device, and an attachment method for the in-vehicle device will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0012] For ease of understanding, each of the drawings referred to below shows a Cartesian coordinate system in which mutually orthogonal X-, Y-, and Z-axis directions are defined, with the positive Z-axis direction being the vertically upward direction. In the following description, the XY plane is the horizontal plane, and the positive X-axis direction is the forward direction of the vehicle on which the on-board device is installed.

[0013] Therefore, the positive Y-axis direction is the right direction when the driver is facing the forward direction of the vehicle. The positive Z-axis direction is the vertically upward direction. For convenience, the positive Z-axis direction may be referred to as up, the negative Z-axis direction as down, the positive X-axis direction as front, the negative X-axis direction as rear, the positive Y-axis direction as right, and the negative Y-axis direction as left.

[0014] [1. Configuration of the on-board device] Fig. 1 is a perspective view showing an attached state of an in-vehicle device 1 according to an embodiment. Fig. 2 is a perspective view showing an attachment part 2 according to an embodiment. Figs. 3 and 4 are perspective views showing an in-vehicle device main body 3 according to an embodiment. Figs. 5 and 6 are perspective views showing a fixing part 4 according to an embodiment.

[0015] The vehicle-mounted device 1 is, for example, a drive recorder. Note that the vehicle-mounted device 1 according to the embodiment is not limited to a drive recorder. The vehicle-mounted device 1 according to the embodiment may be any vehicle-mounted device 1 other than a drive recorder, such as an in-vehicle radar device attached to a glass window of a vehicle.

[0016] As shown in Fig. 1, the vehicle-mounted device 1 includes an attachment part 2 attached to a window glass 100 of a vehicle, a vehicle-mounted device main body 3, and a fixing part 4 that fixes the vehicle-mounted device main body 3 to the attachment part 2. The window glass 100 is a windshield. However, the window glass 100 may also be a rear window.

[0017] As shown in FIG. 2 , the mounting part 2 includes an attachment portion 21 that is attached to the window glass 100, and a rod-shaped hanging portion 22 from which the vehicle-mounted device main body 3 is suspended. The attachment portion 21 is a pair of flat plate-shaped members. Double-sided tape is attached to the attachment surface of the attachment portion 21 that is attached to the window glass 100. The attachment portion 21 is attached to the window glass 100 by the double-sided tape. The hanging portion 22 extends along the back surface of the attachment surface of the attachment portion 21, and is installed between the pair of attachment portions 21.

[0018] 3 and 4, the vehicle-mounted device main body 3 includes a housing 31 and a semi-cylindrical first contact portion 32 that contacts at least a portion of the outer circumferential surface of the hanging portion 22. The housing 31 is provided with a camera on the front side that captures images of the vehicle's surroundings, and a display device on the rear side that displays the captured images. The housing 31 also houses a storage device and the like that stores the captured images.

[0019] The first contact portion 32 is formed integrally with the housing 31. The first contact portion 32 is provided at a corner between the front and top surfaces of the housing 31. A plurality of ribs 33 are provided between the first contact portion 32 and the front surface of the housing 31 to suppress deformation of the first contact portion 32. The housing 31 also has a pair of mating claws 34 on its top surface. The mating claws 34 are provided so as to extend from the front to the rear of the top surface of the housing 31.

[0020] 5 and 6, the fixed part 4 includes a flat base 41 and a semi-cylindrical second contact part 42 that contacts at least a portion of the outer circumferential surface of the hanging part 22. The base 41 and the second contact part 42 are integrally formed. The fixed part 4 is provided with a plurality of ribs 43 between the base 41 and the second contact part 42 to suppress deformation of the second contact part 42. The base 41 is also provided with fitting holes 44 into which the fitting claws 34 are fitted.

[0021] [2. How to install the vehicle unit] 7 to 13 are explanatory diagrams showing the steps of installing the vehicle-mounted device 1 according to the embodiment. When installing the vehicle-mounted device 1 in a vehicle, as shown in FIG. 7, first, the installation part 2 is installed on the window glass 100 of the vehicle.

[0022] At this time, the backing of the double-sided tape attached to the attachment surface of attachment portion 21, i.e., the surface of attachment portion 21 opposite to the surface on which rod-shaped hanging portion 22 is provided, is peeled off. Then, the adhesive surface of the double-sided tape is brought into contact with window glass 100, and attachment portion 21 is attached to window glass 100. At this time, mounting part 2 is attached to window glass 100 so that the extension direction of rod-shaped hanging portion 22 is parallel to the horizontal plane.

[0023] Next, as shown in Fig. 8, the vehicle-mounted device main body 3 is held with one hand with the inner circumferential surface of the first abutment portion 32 of the vehicle-mounted device main body 3 abutting against the outer circumferential surface of the hanging portion 22. Then, with the other hand, the fixing part 4 is slid from the rear side to the front side of the vehicle-mounted device main body 3 along the upper surface of the vehicle-mounted device main body 3 so that the inner circumferential surface of the second abutment portion 42 of the fixing part 4 abuts against the outer circumferential surface of the hanging portion 22, as shown in Fig. 9.

[0024] 10 , a slit-shaped guide portion 37 that guides the left-right end portion 45 of the base 41 of the fixed part 4 is provided on the upper surface of the housing 31 of the vehicle-mounted device main body 3. When the inner peripheral surface of the second abutting portion 42 of the fixed part 4 is to abut against the outer peripheral surface of the hanging part 22, the fixed part 4 is slid from the rear side to the front side of the vehicle-mounted device main body 3 along the upper surface of the vehicle-mounted device main body 3 with the end portion 45 of the base 41 fitted into the guide portion 37 of the housing 31.

[0025] This restricts the movement of the fixed part 4 in the left-right and up-down directions. After that, with the hanging part 22 sandwiched between the first abutment part 32 and the second abutment part 42, the fixed part 4 and the vehicle-mounted device main body 3 are engaged with each other by claws, and the vehicle-mounted device main body 3 is fixed to the mounting part 2.

[0026] 11 to 13 show cross sections taken along line AA shown in Fig. 10. In the process of claw-fitting the fixed part 4 and the vehicle-mounted device main body 3, as shown in Fig. 11, the second abutment part 42 is moved in the direction of the hanging part 22, that is, from rear to front, with the height positions of the base part 41 of the fixed part 4 and the fitting claws 34 of the housing 31 aligned.

[0027] Thereafter, as shown in FIG. 12, after the base 41 of the fixed part 4 and the wedge portion at the tip of the fitting claw 34 come into contact, when the fixed part 4 is continuously moved from rear to front, the fitting claw 34 elastically deforms downward and slips under the base 41.

[0028] Then, when the fixing part 4 is further moved from the rear to the front, as shown in FIG. 13, the wedge portion at the tip of the fitting claw 34 fits into the fitting hole 44 provided in the base 41 of the fixing part 4, and the claw fitting between the fixing part 4 and the vehicle-mounted device main body 3 is completed.

[0029] In this way, the vehicle-mounted device 1 of the embodiment holds the vehicle-mounted device main body 3 in a state where the first abutment portion 32 of the vehicle-mounted device main body 3 abuts against the hanging portion 22 of the mounting part 2 attached to the window glass 100, and installation is completed by engaging the fixing part 4 and the vehicle-mounted device main body 3 with their claws.

[0030] That is, when the vehicle-mounted device 1 is attached to the window glass 100, the attachment work can be completed without inserting a hand between the window glass 100 and the vehicle-mounted device main body 3. Therefore, the vehicle-mounted device 1 does not need to have a space between the window glass 100 and the vehicle-mounted device main body 3 for tightening a fixing screw of a ball joint, for example.

[0031] Therefore, compared to the case where a ball joint is used, the in-vehicle device 1 can shorten the distance from the window glass 100 to the in-vehicle device main body 3, making it possible to make the attachment part 2 attached to the window glass 100 less likely to be in the driver's field of view. Details of this effect will be described later with reference to FIG. 16.

[0032] [3. Shape Examples of the Hanging Portion, First Contact Portion, and Second Contact Portion According to the Embodiment] 14 is an explanatory diagram showing an example of the shapes of the hanging portion 22, the first contact portion 32, and the second contact portion 42 according to the embodiment. FIG. 15 is an enlarged view of the area enclosed by the dashed line in FIG.

[0033] 14 and 15, the rod-shaped suspending portion 22 has an externally toothed gear-shaped external toothed portion 23 on at least a portion of its outer circumferential surface. Also, as shown in Fig. 15, the second contact portion 42 of the fixed part 4 has an internally toothed gear-shaped internal toothed portion 46 that meshes with the externally toothed portion 23 of the suspending portion 22 on at least a portion of its inner circumferential surface. Also, the first contact portion 32 of the vehicle-mounted device main body 3 has an internally toothed gear-shaped internal toothed portion (not shown) that meshes with the externally toothed portion 23 of the suspending portion 22 on at least a portion of its inner circumferential surface.

[0034] As a result, the angle of the vehicle-mounted device 1 can be determined by engaging the internal teeth of the first abutment portion 32 with the external teeth 23 of the hanging portion 22 in a state where the angle of the vehicle-mounted device main body 3 is the desired angle before being fixed by the fixing part 4.

[0035] Thereafter, when the fixing part 4 and the vehicle-mounted device main body 3 are engaged with each other by the claws, the vehicle-mounted device main body 3 is fixed in a state in which the internal teeth of the first abutment part 32 are engaged with the external teeth 23 of the hanging part 22. This prevents the vehicle-mounted device main body 3 from rotating with respect to the hanging part 22 after being fixed to the mounting part 2 by the fixing part 4. In other words, the angle of the vehicle-mounted device main body 3 can be fixed when the mounting of the vehicle-mounted device 1 to the mounting part 2 is completed.

[0036] The internal teeth portion 46 and the external teeth portion 23 have sharp tips before the in-vehicle device main body 3 and the fixed part 4 are claw-fitted together. The external teeth portion 23 is made of a softer material than the internal teeth portion 46.

[0037] The external teeth portion 23 is deformed by the fastening part 4 being claw-fitted to the vehicle-mounted device main body 3, and fills the gap (see FIG. 15 ) between it and the internal teeth portion 46. This makes it possible to prevent the vehicle-mounted device 1 from rattling due to the gap between the internal teeth portion 46 and the external teeth portion 23, even if vibrations occur as the vehicle travels.

[0038] Furthermore, when the vehicle-mounted device 1 becomes loose due to aging of the external tooth part 23, the looseness can be eliminated by simply replacing the mounting part 2 with a new one, without replacing the housing 31 of the vehicle-mounted device main body 3 and the fixing part 4.

[0039] The internal teeth portion 46 may be formed of a material softer than the external teeth portion 23. In this case, the internal teeth portion 46 is deformed by the fastening part 4 being claw-fitted to the vehicle-mounted device main body 3, filling the gap between it and the external teeth portion 23. This makes it possible to suppress rattles in the vehicle-mounted device 1 caused by the gap between the internal teeth portion 46 and the external teeth portion 23, even when vibrations occur as the vehicle travels.

[0040] Furthermore, when the vehicle-mounted device 1 becomes loose due to aging of the internal teeth portion 46, the looseness can be eliminated by simply replacing the fixed part 4 with a new one, without replacing the housing 31 of the vehicle-mounted device main body 3 and the mounting part 2.

[0041] [4. Effects of the in-vehicle device according to the embodiment] Fig. 16 is a side view showing the mounted state of the vehicle-mounted device 1 according to the embodiment. The vehicle-mounted device 1 is fixed to the mounting part 2 by fitting the fixing part 4 and the vehicle-mounted device main body 3 with hooks, so that the distance between the window glass 100 and the vehicle-mounted device main body 3 can be made as short as possible, as shown in Fig. 16.

[0042] This reduces the length D1 of the vehicle-mounted device 1 from the upper end of the affixing portion 21 of the mounting part 2 attached to the window glass 100 to the upper end of the vehicle-mounted device main body 3. As a result, the vehicle-mounted device 1 becomes less likely to be in the driver's field of view because the vertical length D2 of the entire vehicle-mounted device 1 (including the vehicle-mounted device main body 3 and the mounting part 2) that is in the driver's field of view is reduced.

[0043] [5. Modifications] In the above embodiment, the case where the fitting claws 34 are provided on the vehicle-mounted device main body 3 and the fitting holes 44 are provided on the fixed part 4 has been described, but this is just an example. The fitting claws 34 may be provided on the fixed part 4. In this case, the fitting holes 44 are provided on the vehicle-mounted device main body 3.

[0044] Even with this configuration, the vehicle-mounted device 1 is attached and fixed to the fixing part 4 by the claw engagement between the fixing part 4 and the vehicle-mounted device main body 3, so it is less likely to be in the driver's field of view, just like the vehicle-mounted device 1 in the above-mentioned embodiment.

[0045] Furthermore, the vehicle-mounted device 1 may be provided with an elastic member between the first contact portion 32 and the second contact portion 42 and the hanging portion 22. The elastic member may be, for example, a rubber or silicone sheet with an anti-slip function that covers at least a part of the outer circumferential surface of the hanging portion 22.

[0046] As a result, even if a small gap remains between the first contact portion 32 and the second contact portion 42 and the hanging portion 22, the gap is filled by the elastic member. Therefore, the vehicle-mounted device 1 can more effectively suppress the occurrence of rattle caused by the gap between the internal tooth portion 46 and the external tooth portion 23.

[0047] When an elastic member is provided, at least one of the internal teeth portion of the first contact portion 32, the internal teeth portion 46 of the second contact portion 42, and the external teeth portion 23 of the hanging portion 22 does not have to be provided. In this case, the elastic member functions as an anti-slip member, so that the vehicle-mounted device 1 can prevent the first contact portion 32 and the second contact portion 42 from rotating relative to the hanging portion 22. In other words, the vehicle-mounted device 1 can prevent changes in the installation angle due to vibrations or the like.

[0048] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
