[0005] Patent document 1: JP Patent No. 5853795. Summary of the invention

[0006] Problem that the invention aims to solve

[0007] In the bracket shown in Patent Document 1, a leaf spring is indispensable for pressing the back of the vehicle-mounted camera device from the rear side of the vehicle, so it is difficult to minimize the size of the bracket in the front-rear direction of the vehicle. In addition, the vehicle-mounted camera device assembled on the bracket is held by the load of the leaf spring, so it is not possible to completely prevent the vehicle-mounted camera device from rattling.

[0008] The main problem to be solved by the present invention is to enable such a vehicle-mounted camera device bracket to be reasonably and appropriately compact.

[0009] Means used to solve problems

[0010] In order to solve the above-mentioned problem, in the present invention, a bracket for a vehicle-mounted camera device is a bracket for mounting a vehicle-mounted camera device for photographing the outside of a vehicle through a window glass on the window glass, wherein:

[0011] A base portion fixed to a surface of the window glass located on the inner side of the vehicle;

[0012] A snap-fitting piece, which slides and moves by operating the vehicle-mounted camera device, so that the snap-fitting portion snaps into the end portion of the vehicle-mounted camera device located at the rear side during the movement;

[0013] The engaging piece has a fixed end portion integrated with the base portion and a free end portion spaced apart from the fixed end portion in the front-rear direction of the vehicle, the engaging portion is arranged at the free end portion, and the engaging portion is elastically deformed by abutting against the vehicle-mounted camera device, thereby allowing the moving operation, and the engaging portion is engaged by elastic recovery of the engaging piece at the end position of the moving operation.

[0014] According to the above configuration, the vehicle-mounted camera device is operated to slide relative to the bracket and embedded in the bracket from the state where the bracket is fixed to the window glass, so that the engaging portion of the engaging piece is engaged with the end of the vehicle-mounted camera device located at the rear side during the movement in a one-touch manner, and the vehicle-mounted camera device can be stably installed on the window glass. That is, by the above engagement, the vehicle-mounted camera device is prevented from moving in the opposite direction to the operation of the sliding movement, and is maintained at a predetermined embedded position relative to the bracket. Since the engaging piece is configured as follows: the fixed end is integrated with the base portion fixed to the window glass, and the free end portion arranged with a gap between the fixed end portion and the free end portion in the front-to-back direction of the vehicle has the engaging portion, it is not necessary to provide a portion on the bracket that is opposite to the end of the vehicle-mounted camera device located at the rear side during the movement, nor is it necessary to provide a spring portion on the bracket that elastically presses the end of the vehicle-mounted camera device located at the rear side during the movement from the portion, so that the size of the bracket in the front-to-back direction of the vehicle is minimized. That is, the above-mentioned structure contributes to the compactness of the bracket, improves the degree of freedom in the design of the bracket, and promotes the simplification of the structure of the bracket. This also minimizes the area occupied by the bracket on the window glass.

[0015] As one embodiment of the present invention, the bracket is an injection-molded product of a synthetic resin.

[0016] In addition, as one embodiment of the present invention, the locking portion is configured as a protrusion protruding downward, one side across the top of the locking portion is a contact surface that contacts the vehicle-mounted camera device when engaged with the vehicle-mounted camera device, and the other side across the top is an inclined surface.

[0017] Effects of the Invention

[0018] According to the present invention, it is possible to rationally and appropriately make such a vehicle-mounted camera device bracket compact. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] Below, according to Figure 1 to Figure 7 , a typical embodiment of the present invention is described. The bracket 3 of this embodiment is used to install the vehicle-mounted camera device 2 for shooting the outside of the vehicle through the window glass of the vehicle on the window glass. Typically, the bracket 3 is used to install the vehicle-mounted camera device 2 for shooting the outside of the vehicle through the front window 1 of the car on the front window 1. In addition, the concept of the vehicle-mounted camera device 2 in this specification is not only a camera device in a narrow sense, but also includes well-known devices such as sensors that receive optical information.

[0027] Figure 7 In the figure, reference numeral 1 is a front window, reference numeral 3 is a bracket, and reference numeral 2 is a vehicle-mounted camera device. Figure 1 In the figure, the front side of the vehicle is indicated by the reference symbol x. Figure 1 In the figure, the rear side of the vehicle is indicated by the reference symbol xa. Figure 1 In addition, the left and right directions of the vehicle are Figure 1 In the figure, it is represented by the reference symbol y.

[0028] The front window 1 has an inclination that makes the front side xa of the vehicle tilt downward. The bracket 3 is fixed to the surface 1a located on the vehicle inner side of the front window 1. The vehicle-mounted camera device 2 is mounted on the front window 1 by sliding relative to the bracket 3 and inserting into the bracket 3 from the state where the bracket 3 is fixed to the front window 1.

[0029] In the example shown in the figure, the vehicle-mounted camera device 2 is inserted into the bracket 3 by sliding the vehicle-mounted camera device 2 from the rear side xb of the vehicle toward the front side xa of the vehicle substantially along the front-rear direction x of the vehicle.

[0030] In the example shown in the figure, the vehicle-mounted camera device 2 is mounted on the front window 1 via a bracket 3 so that the light incident portion 2 a for photographing faces the front side xa of the vehicle. Figure 7 The reference numeral 2b in the figure indicates the camera body. In the example shown in the figure, the camera body 2b has a step portion 2e facing the front side xa of the vehicle between its front end portion 2c and rear end portion 2d, and the light input portion 2a is provided on the step portion 2e. The camera body 2b is arranged such that the vertical direction z (refer to Figure 7 ) is small, and the dimension in the up-down direction z is large between the step portion 2e and the rear end portion 2d.

[0031] The bracket 3 includes: a base portion 4, which is fixed to the surface 1a of the front window 1 serving as the window glass and located on the inner side of the vehicle; and a locking piece 5, which is slidably moved by operating the vehicle-mounted camera device 2 so that the locking portion 5a is locked to the end portion of the vehicle-mounted camera device 2 located on the rear side during the movement, and in the example shown in the figure, is locked to the rear end portion 2d.

[0032] The engaging piece 5 has a fixed end 5e integrated with the base 4 and a free end 5f arranged at a distance from the fixed end 5e in the front-rear direction x of the vehicle. In the illustrated example, the engaging piece 5 has the fixed end 5e located at the rear end 4b side of the base 4 and at the middle position of the base 4 in the left-right direction of the vehicle, and the free end 5f located behind the fixed end 5e. In the illustrated example, the free end 5f of the engaging piece 5 protrudes slightly rearward from the rear end 4b of the base 4.

[0033] The engaging piece 5 has the engaging portion 5a at the free end portion 5f. In this embodiment, the engaging portion 5a is in the shape of a protrusion protruding downward.

[0034] The engaging piece 5 involved is thus constructed so that the engaging portion 5a abuts against the vehicle-mounted camera device 2 to cause the engaging piece 5 to be elastically deformed, thereby allowing the vehicle-mounted camera device 2 to be operated to perform the sliding movement, and the engaging portion 5a is engaged by elastic recovery of the engaging piece 5 at the end position of the movement operation.

[0035] Thus, in this embodiment, the vehicle-mounted camera device 2 is operated to slide relative to the bracket 3 and fit into the bracket 3 from the state where the bracket 3 is fixed to the front window 1 as the window glass, so that the engaging portion 5a of the engaging piece 5 is engaged with the end portion of the vehicle-mounted camera device 2 located at the rear side during the movement in a one-touch manner, and the vehicle-mounted camera device 2 can be stably mounted on the window glass. That is, by the engagement, the vehicle-mounted camera device 2 is prevented from moving in the opposite direction to the sliding operation, and is maintained at a predetermined embedding position relative to the bracket 3. Since the engaging piece 5 is configured as follows: the fixed end portion 5e is integrated with the base portion 4 fixed to the window glass, and the free end portion 5f arranged at a distance from the fixed end portion 5e in the front-rear direction x of the vehicle has the engaging portion 5a, it is not necessary to provide a portion on the bracket 3 that is opposite to the end portion of the vehicle-mounted camera device 2 located at the rear side during the movement, nor is it necessary to provide a spring portion on the bracket 3 that elastically presses the end portion of the vehicle-mounted camera device 2 located at the rear side during the movement from the portion, and the size of the bracket 3 in the front-rear direction x of the vehicle is minimized. That is, the configuration helps to make the bracket 3 compact, improves the degree of freedom in the design of the bracket 3, and promotes the simplification of the structure of the bracket 3. This also minimizes the area occupied by the bracket 3 on the window glass.

[0036] In the example shown in the figure, the bracket 3 includes the base portion 4 , the engaging piece 5 , a front support portion 6 supporting the front end portion 2 c of the vehicle-mounted camera device 2 , and a rear support portion 7 supporting the rear end portion 2 d of the vehicle-mounted camera device 2 .

[0037] An open portion 4e is formed between the front end 4a and the rear end 4b of the base portion 4. The open portion 4e receives the light incident portion 2a of the vehicle-mounted camera device 2 from the rear side xb of the vehicle as the vehicle-mounted camera device 2 slides as described above.

[0038] A light guide groove 4f is formed in the upper surface 4c of the base portion 4 between the front end 4a and the open portion 4e. The light guide groove 4f is formed such that the groove width in the left-right direction y gradually narrows as it approaches the open portion 4e.

[0039] In the upper surface 4c of the base 4, except for the light guide groove 4f, Figure 1The portion other than the eliminated portion indicated by the reference numeral 4g in the figure becomes the mounting surface 4h for the front window 1. In the example shown in the figure, the bracket 3 is mounted on the front window 1 by bonding using the mounting surface 4h. The mounting surface 4h is mounted so that the entirety thereof is in close contact with the surface 1a of the front window 1 located on the vehicle interior side, and has an inclination that imitates the inclination of the front window 1.

[0040] The front side support portion 6 is provided between the front end 4a of the base portion 4 and the open portion 4e at a middle position in the left-right direction y. The front side support portion 6 has a base portion 6a protruding in the vertical direction from the bottom 4d of the base portion 4, and a protrusion 6b protruding from the lower end of the base portion 6a toward the rear side of the vehicle, and has a hook-shaped longitudinal cross section. When the vehicle-mounted camera device 2 is operated to slide from the state in which the bracket 3 is mounted on the front window 1 to the direction along the front-rear direction x of the vehicle so as to be embedded in the bracket 3 from the rear, the front end portion 2c of the vehicle-mounted camera device 2 enters between the bottom 4d of the base portion 4 and the protrusion 6b, and at the embedding end position ( Figure 7 ), the front end portion 2c collides with the base 6a, and the protrusion 6b supports the front end portion 2c from below.

[0041] The rear support part 7 is respectively provided at a corner where the rear end 4b of the base part 4 is connected to one side along the front-back direction and at a corner where the rear end 4b of the base part 4 is connected to the other side along the front-back direction. That is, in the example shown in the figure, the rear support part 7 is respectively provided on the left and right sides of the base part 4. The distance between the inner surfaces of the left and right rear support parts 7 (the surface on the side opposite to the rear support part 7 on the other side) is substantially equal to the size of the vehicle-mounted camera device 2 in the left-right direction. Support ribs 7a are respectively formed on the inner surfaces of the left and right rear support parts 7, and the support ribs 7a include longitudinal ribs 7b extending in the vertical direction and transverse ribs 7c extending rearwardly from the lower end of the longitudinal ribs 7b. In the example shown in the figure, the distance between the transverse ribs 7c of the support ribs 7a and the portion 5g from the fixed end 5e of the engaging piece 5 to the engaging part 5a is substantially equal to the upper and lower dimensions of the rear end 2d side of the vehicle-mounted camera device 2. When the vehicle-mounted camera device 2 is operated to slide and move in the direction along the front-rear direction x of the vehicle from the state where the bracket 3 is mounted on the front window 1 so as to be embedded in the bracket 3 from the rear, at the embedding end position ( Figure 7 ), the unillustrated step portions formed on the left and right side surfaces of the vehicle-mounted camera device 2 located on the side of the rear end portion 2d collide with the longitudinal rib 7b, and the transverse rib 7c supports the bottom of the vehicle-mounted camera device 2 located on the side of the rear end portion 2d from below.

[0042] That is, in the example shown in the figure, the vehicle-mounted camera device 2 is inserted into the insertion space 8 formed by the lower surface 4d of the base portion 4 of the bracket 3, the front support portion 6, and the left and right rear support portions 7 by the sliding movement operation from the rear side xb of the vehicle.

[0043] When the vehicle-mounted camera device 2 is operated to slide, the engaging portion 5 a of the engaging piece 5 abuts against a portion 2 f of the upper surface of the vehicle-mounted camera device 2 between the light incident portion 2 a and the rear end portion 2 d .

[0044] The engaging piece 5 is in the shape of a long strip between the open portion 4e and the rear end 4b of the base 4, and has upper and lower plate surfaces with a wide width extending substantially horizontally from the base 5h toward the rear, and the base 5h protrudes downward from the lower surface 4d of the base 4, and the base 5h constitutes the fixed end 5e. A gap 9 is formed between the engaging piece 5 and the lower surface 4d of the base 4, which gradually increases as it approaches the free end 5f of the engaging piece 5 (see Figure 6 ).

[0045] The engagement portion 5 a is in the shape of a rib formed at a free end portion 5 f of the engagement piece 5 across the left-right direction of the engagement piece 5 .

[0046] The side of the engaging portion 5a across the top 5b is a contact surface 5c that contacts the vehicle-mounted camera device 2 when engaging with the vehicle-mounted camera device 2, and the other side across the top 5b is an inclined surface 5d. In the example shown in the figure, the contact surface 5c substantially along the vertical direction is formed on the front side of the engaging portion 5a, and the inclined surface 5d is formed on the rear side of the engaging portion 5a. The inclined surface 5d makes the engaging portion 5a have a shape in which the size in the front-rear direction x gradually decreases as it moves toward the top 5b.

[0047] In this embodiment, the engaging portion 5a abuts against the portion of the upper surface of the vehicle-mounted camera device 2 between the light-entering portion 2a and the rear end portion 2d on the inclined surface 5d during the operation of the vehicle-mounted camera device 2 to slide. When the abutment occurs, the engaging portion 5a is elastically deformed upward smoothly through the inclined surface 5d, allowing the rear end portion 2d side of the vehicle-mounted camera device 2 to be introduced between the transverse rib 7c of the rear support portion 7 and the engaging portion 5a. When the embedding of the vehicle-mounted camera device 2 into the bracket 3 is completed, specifically, when the vehicle-mounted camera device 2 is embedded to the position where the front end portion 2c of the vehicle-mounted camera device 2 hits the base 6a of the front support portion 6, since the top 5b of the engaging portion 5a is located behind the corner 2g on the upper surface of the rear end portion 2d side of the vehicle-mounted camera device 2 that is connected to the rear end portion 2d, the engaging piece 5 is elastically restored, so that the contact surface 5c contacts the rear end portion 2d, and the engaging portion 5a is hooked on the rear end portion 2d. As a result, the vehicle-mounted camera device 2 is stably held in the bracket 3 .

[0048] In this embodiment, the bracket 3 is an injection-molded product of synthetic resin, so that the bracket 3 is integrated and the required elastic deformation characteristics can be reasonably given to the engaging piece 5.

[0049] In addition, it is needless to say that the present invention is not limited to the above-described embodiments, but includes all embodiments that can achieve the object of the present invention.
