Description

[Technical field]

[0001] The present disclosure relates to a bracket mounting structure that detachably mounts a bracket, to which a radar unit is attached, to an outer lens. [Background technology]

[0002] Patent Document 1 describes a bracket mounting structure for detachably mounting a bracket (support member) on which a radar unit is mounted to a housing (see, in particular, FIG. 2 of Patent Document 1). The radar unit is used to detect objects by transmitting high-frequency electromagnetic waves (e.g., millimeter waves) to the vicinity of the vehicle and receiving reflected waves from objects present within the transmission range. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-001451 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, Patent Document 1 does not describe or suggest a bracket mounting structure for removably mounting the bracket (support member) on which the radar unit is mounted to the outer lens (a recessed portion recessed toward the housing side), leaving room for improvement.

[0005] The present disclosure has been made to solve such problems, and has an object to provide a bracket mounting structure that detachably mounts a bracket, on which a radar unit is mounted, to an outer lens. [Means for solving the problem]

[0006] The bracket mounting structure according to the present disclosure is a bracket mounting structure for detachably mounting a bracket to an outer lens which is attached to a lamp housing and which constitutes a lamp chamber in which a lamp unit is disposed between the outer lens and the lamp housing, the outer lens including a recess which is recessed toward the lamp housing, the outer lens including a bracket main body which is disposed within the recess with the rear surface facing a bottom surface of the recess, and an extension part which extends from the other end side opposite to the one end side of the bracket main body to the outside of the recess and is detachably fixed to a mounting partner, the bracket mounting structure comprising: an inner wall of the recess and one end side of the bracket main body; an engaging portion is provided on the inner wall of the recess and the other of the one end sides of the bracket main body, an engaging portion that engages with the engaged portion is provided on the other of the inner wall of the recess and the one end side of the bracket main body, a regulating portion that protrudes toward the other is provided on the bottom surface of the recess of the outer lens and one of the bracket main body, and a fitting recess into which the regulating portion is inserted and fitted is provided on the other of the bottom surface of the recess of the outer lens and the other of the bracket main body, and the bracket is fixed to the outer lens with the engaging portion engaging with the engaged portion, the extension portion fixed to the mounting partner, and the regulating portion inserted and fitted in the recess.

[0007] With this configuration, it is possible to provide a bracket mounting structure that detachably mounts the bracket, to which the radar unit is attached, to the outer lens.

[0008] According to this bracket mounting structure, the bracket can be detachably mounted to the outer lens (a recess recessed toward the housing) by engaging the engaging portion with the engaged portion and fixing the extension portion to the mounting partner. At that time, the restricting portion is inserted into the fitting recess and engages with it. This restricts the movement of the bracket in the up, down, left, and right directions, so the bracket can be stably mounted to the outer lens (recess). This realizes a bracket mounting structure in which the bracket is unlikely to shift in position relative to the outer lens even when vibrations (mainly vibrations when the vehicle is traveling) are applied, that is, which can suppress unintended up, down, left, and right movement.

[0009] In the above bracket mounting structure, the regulating portion includes a pair of upper and lower upper and lower regulating surfaces, the mating recess includes an upper surface that makes face-to-face contact with the upper regulating surface and a lower surface that makes face-to-face contact with the lower regulating surface, and when the regulating portion is inserted into the mating recess and mated, the upper surface of the mating recess makes face-to-face contact with the upper regulating surface of the regulating portion and the lower surface of the mating recess makes face-to-face contact with the lower regulating surface of the regulating portion, thereby regulating vertical movement of the bracket.

[0010] In addition, in the above bracket mounting structure, the regulating portion further includes a pair of left and right regulating surfaces, and the mating recess further includes a left surface that makes face contact with the left regulating surface and a right surface that makes face contact with the right regulating surface, and when the regulating portion is inserted into the mating recess and mated, the left surface of the mating recess makes face contact with the left regulating surface of the regulating portion and the right surface of the mating recess makes face contact with the right regulating surface of the regulating portion, thereby regulating left-right movement of the bracket.

[0011] In addition, in the above bracket mounting structure, the regulating portion may be inserted into the mating recess and fitted into the mating recess by engaging the engaging portion with the engaged portion and rotating the bracket toward the outer lens side using the engaged engaging portion as a fulcrum.

[0012] In addition, in the above bracket mounting structure, the upper and lower regulating surfaces which are closer to the engagement portion may be configured as inclined surfaces so as to be easily inserted into the mating recess when the bracket is rotated.

[0013] In the above bracket mounting structure, the engaged portion may be a groove, and the engaging portion may be a protrusion inserted into the groove. Effect of the Invention

[0014] The present disclosure makes it possible to provide a bracket mounting structure that detachably mounts a bracket, to which a radar unit is attached, to an outer lens. [Brief description of the drawings]

[0016] Hereinafter, a vehicle lamp to which a bracket mounting structure according to an embodiment of the present disclosure is applied will be described with reference to the accompanying drawings. In each drawing, corresponding components are given the same reference numerals, and duplicated explanations will be omitted.

[0017] The vehicle lamp 10 of this embodiment is a vehicle lamp that functions as a headlamp and is mounted on both the left and right sides of the front end of a vehicle such as an automobile (not shown). Since the vehicle lamps 10 mounted on both the left and right sides have a symmetrical configuration, the vehicle lamp 10 mounted on the left side of the front end of the vehicle (the left side when facing the front of the vehicle) will be described below as a representative example.

[0018] 1 is a perspective view of the vicinity of a vehicle lamp 10 mounted on a vehicle, FIG. 2 is a view seen from the direction of arrow Ar1 in FIG. 1, FIG. 3 is a top view of the vehicle lamp 10, FIG. 4 is a cross-sectional view taken along line AA in FIG. 2, FIG. 5 is a cross-sectional view taken along line BB in FIG. 2, FIG. 6 is a cross-sectional view taken along line CC in FIG. 2, and FIG. 7 is a cross-sectional view taken along line DD in FIG. 2.

[0019] As shown in Fig. 3 to Fig. 7, the vehicle lamp 10 includes a lamp housing 20 (see Fig. 5), an outer lens 30, a lamp unit 40, a bracket 50, a radar cover 60, and a radar unit 70. Reference numeral 90 in Fig. 1 and Fig. 3 denotes a bumper. Reference numeral 100 in Fig. 3 denotes a vehicle body.

[0020] The outer lens 30 is attached to the lamp housing 20, and forms a lamp chamber in which the lamp unit 40 is disposed between the outer lens 30 and the lamp housing 20. The lamp unit 40 may have any configuration as long as it is a lamp unit that irradiates light that functions as a headlamp. For example, the lamp unit 40 may be a projector type lamp unit, a reflector type lamp unit, a direct projection type lamp unit, a lamp unit using a light guide (light guide rod, light guide plate), or a lamp unit other than these.

[0021] FIG. 8 is a front view of the outer lens 30. As shown in FIG.

[0022] 4 and 8, the outer lens 30 is made of a transparent resin (synthetic resin) such as acrylic or polycarbonate, and includes a lens portion 31 through which the light emitted by the lamp unit 40 passes, a recess 32 recessed from the front side toward the rear side (the lamp housing 20 side), and a groove portion 33 (see the enlarged view within circle C1 in FIG. 4) formed on an inner wall 32b (upper inner wall 32b1) of the recess 32. The groove portion 33 is an example of an engaged portion of the present disclosure.

[0023] The lens portion 31 is disposed on the inner side in the vehicle width direction, and the recessed portion 32 is disposed on the outer side in the vehicle width direction (see FIG. 3). The recessed portion 32 is composed of a bottom surface 32a on the rear side, and inner walls 32b (upper inner wall 32b1, lower inner wall 32b2, inner inner wall 32b3, and outer inner wall 32b4) (see FIGS. 4 to 8).

[0024] The groove 33 is a groove into which the protrusion 52 provided on the upper side of the bracket 50 (bracket body 51) is inserted. The groove 33 (two places) is formed in the upper inner wall 32b1 of the recess 32 (see FIG. 8). Specifically, the groove 33 is formed between the first protrusion 33a on the front side protruding from the upper inner wall 32b1 and the second protrusion 33b on the rear side (see the enlarged view in the circle C1 in FIG. 4). The groove 33 extends in a direction perpendicular to the paper surface in FIG. 4. The groove 33 may be formed directly in the inner wall 32b (upper inner wall 32b1) of the recess 32 as shown in FIG. 9. FIG. 9 shows a modified example of the groove 33.

[0025] Furthermore, the bottom surface 32a of the recess 32 of the outer lens 30 is provided with restriction portions 34 (at two locations) that protrude toward the bracket 50 (see FIGS. 5, 7, and 8).

[0026] The restricting portion 34 is a quadrangular pyramid-shaped portion including a pair of upper and lower restricting surfaces, 34a and 34b, and a pair of left and right restricting surfaces, 34c and 34d (see the enlarged views of the circle C2 in Figs. 5, 7, and 8). Note that the restricting portion 34 is not limited to a quadrangular pyramid-shaped portion, and may be a circular cone-shaped portion, a polygonal pyramid-shaped portion, or a portion of another shape.

[0027] When the restricting portion 34 is inserted into and fitted into the fitting recess 54 formed in the bracket 50 (bracket main body 51) (see FIG. 5), the upper surface 54a of the fitting recess 54 comes into surface contact with the upper restricting surface 34a of the restricting portion 34, and the lower surface 54b of the fitting recess 54 comes into surface contact with the lower restricting surface 34b of the restricting portion 34. This restricts the movement of the bracket 50 in the up-down direction. When the restricting portion 34 is inserted into and fitted into the fitting recess 54 formed in the bracket 50 (bracket main body 51) (see FIG. 7), the left surface 54c of the fitting recess 54 comes into surface contact with the left restricting surface 34c of the restricting portion 34, and the right surface 54d of the fitting recess 54 comes into surface contact with the right restricting surface 34d of the restricting portion 34. This restricts the movement of the bracket 50 in the left-right direction.

[0028] Next, the bracket 50 will be described.

[0029] FIG. 10(a) is a perspective view of the bracket 50 as viewed from the front side, and FIG. 10(b) is a perspective view of the bracket 50 as viewed from the rear side.

[0030] 10(a) and 10(b), bracket 50 includes bracket body 51, protruding portion 52, and extension portion (leg portion) 53. Bracket 50 is integrally molded from synthetic resin such as PC (polycarbonate), PBT (polybutylene terephthalate), POS (polyoxymethylene), or the like.

[0031] The bracket body 51 includes a radar unit mounting surface 51a (front surface) and a rear surface 51b on the opposite side. The radar unit mounting surface 51a is provided with screw bosses 51a1 (three locations) to which the radar unit 70 is screwed (see FIG. 10(a) and the like). The bracket body 51 is also provided with a fitting recess 54 into which the restricting portion 34 (tip portion) provided on the bottom surface 32a of the recess 32 of the outer lens 30 is inserted and fitted (see FIGS. 5, 7, and 10(b)). The fitting recess 54 is a quadrangular pyramid-shaped recess including an upper surface 54a and a lower surface 54b (see FIG. 5) corresponding to the upper restricting surface 34a and the lower restricting surface 34b, and a left surface 54c and a right surface 54d (see FIG. 7) corresponding to the left restricting surface 34c and the right restricting surface 34d. The fitting recess 54 may be a recess into which the restricting portion 34 is inserted and fitted, and may be a recess having a truncated cone shape, a truncated polygonal pyramid shape, or another shape, without being limited to a quadrangular pyramid shape.

[0032] The protrusions 52 (two locations) are provided on the upper side (an example of one end side of the present disclosure) of the bracket body 51 in correspondence with the grooves 33 (two locations) formed in the inner wall 32b (upper inner wall 32b1) of the recess 32 (see FIG. 10(a) and the like). The protrusions 52 are an example of an engagement portion of the present disclosure.

[0033] The extension portion 53 is provided on the lower side (an example of the other end side of the present disclosure) opposite the upper side of the bracket main body 51. As shown in FIG. 6, the extension portion 53 extends from the lower side of the bracket main body 51 to the first curved portion C 53a and further extends downward through a second curved portion C 53b and is detachably fixed (for example, by a bolt N1; see FIG. 2) to an attachment target (here, the lamp housing 20) outside the recess 32. Note that the attachment target is not limited to the lamp housing 20, and may be the outer lens 30.

[0034] FIG. 11 is a diagram showing how the bracket 50 is attached to the outer lens 30 (the recess 32).

[0035] The bracket 50 having the above configuration is detachably attached to the outer lens 30 (recess 32). Specifically, first, with the rear surface of the bracket 50 facing the bottom surface 32a of the recess 32 of the outer lens 30, the protrusion 52 formed on the upper side of the bracket main body 51 is inserted into and engaged with the groove 33 formed in the inner wall 32b (upper inner wall 32b1) of the recess 32 (see the enlarged view within the circle C1 in FIG. 4).

[0036] Next, the bracket 50 is rotated toward the outer lens 30 (see arrow Ar2 in FIG. 11) with the inserted and engaged protrusion 52 as a fulcrum, thereby inserting the restricting portion 34 into the fitting recess 54 (see FIGS. 5 and 7). At this time, since the upper restricting surface 34a of the restricting portion 34 and the corresponding upper surface 54a of the fitting recess 54 are each configured as an inclined surface (see FIG. 11, etc.), the restricting portion 34 and the fitting recess 54 can be inserted into the fitting recess 54 without interfering with each other. Furthermore, by configuring the upper restricting surface 34a as an inclined surface, the base side of the restricting portion 34 is larger than the tip side, which makes it more resistant to vibration.

[0037] Next, the lower end 53a of the extension 53 provided on the lower side of the bracket 50 is brought close to the mounting target, and the lower end 53a is fixed to the lamp housing 20 (for example, by means of the bolt N1; see FIG. 2).

[0038] In this manner, the bracket 50 is fixed to the outer lens 30 with the protrusion 52 inserted into the groove 33 (see the enlarged view in the circle C1 in FIG. 4), the extension 53 (lower end 53a) fixed to the lamp housing 20 (see FIG. 2), and the regulating portion 34 inserted into the fitting recess 54 and fitted therein (see FIGS. 5 and 7). At this time, the protrusion 52 is biased (pressed) against the first protrusion 33a (the inner wall of the groove 33) on the front side and fixed in an engaged state (see the enlarged view in the circle C1 in FIG. 4). In addition, the upper surface 54a of the fitting recess 54 is in surface contact with the upper regulating surface 34a of the regulating portion 34, and the lower surface 54b of the fitting recess 54 is in surface contact with the lower regulating surface 34b of the regulating portion 34 (see FIG. 5). This restricts the movement of the bracket 50 in the up-down direction. Also, the left surface 54c of the fitting recess 54 is in surface contact with the left restriction surface 34c of the restriction portion 34, and the right surface 54d of the fitting recess 54 is in surface contact with the right restriction surface 34d of the restriction portion 34 (see FIG. 7). This restricts the left-right movement of the bracket 50. Also, since only the tip portion of the restriction portion 34, not the entire portion, is inserted into and fitted into the fitting recess 54, a space S1 (see FIG. 7) is formed between the bracket 50 (bracket body 51) and the outer lens 30 (bottom surface 32a of the recess 32). This space S1 functions as a drainage channel for discharging rainwater, high-pressure cleaning water, and the like that enters from the outside.

[0039] As described above, with the protrusion 52 inserted into the groove 33 (see the enlarged view of the circle C1 in FIG. 4), the extension 53 (lower end 53a) fixed to the lamp housing 20 (see FIG. 2), and the restricting portion 34 inserted into and fitted into the fitting recess 54 (see FIGS. 5 and 7), the bracket 50 is restricted from moving in the up, down, left and right directions, so that the bracket 50 can be stably attached to the outer lens 30 (recess 32). This realizes a bracket attachment structure in which the bracket 50 is unlikely to shift in position relative to the outer lens 30 even when vibrations (mainly vibrations while the vehicle is traveling) are applied, that is, which can suppress unintended up, down, left and right movement.

[0040] The reason why the upper side (e.g., protrusion 52) of bracket 50 (bracket main body 51) is not screwed to the outer lens 30 side is that it is difficult to secure space within the recess 32 of the outer lens 30 to place the screw boss and the bracket fixing screw that screws into it.

[0041] Next, the radar cover 60 will be described.

[0042] The radar cover 60 (see FIG. 2 etc.) is detachably attached to the bracket 50 (bracket body 51). For example, the radar cover 60 is detachably attached to the bracket 50 by engaging a hook portion 56 (see FIGS. 5 and 7) provided on the bracket 50 with the radar cover 60.

[0043] Next, the radar unit 70 will be described.

[0044] FIG. 12 is an exploded perspective view of the bracket 50 and the radar unit 70. As shown in FIG.

[0045] As shown in Fig. 12, a radar unit 70 (radar device) has a case 71, a transmitting antenna, and a receiving antenna (neither of which are shown) housed in the case 71. The radar unit 70 is a millimeter wave radar unit that transmits electromagnetic waves (millimeter waves) from the transmitting antenna. The electromagnetic waves (millimeter waves) pass through the radar cover 60 and spread at a vertical spread angle θ V (See Fig. 6), horizontal spread angle θ H (see FIG. 3). The radar unit 70 receives, by a receiving antenna, the reflected waves that are reflected by objects present within the transmission range and that pass through the radar cover 60. The received signals are processed by a control device, for example, an ECU (Electronic Control Unit) (not shown), and the objects (distance, angle, and speed to the object) are detected. The radar unit 70 uses, for example, millimeter waves in the 76-81 GHz band, particularly millimeter waves in the 79 GHz band, but is not limited to this frequency band.

[0046] The radar system of the radar unit 70 may be any of a pulse system, a CW (Continuous Wave) system, or other systems. The antenna system of the radar unit 70 may be any of a mechanical scanning system, a beam switching system, a phased array system, a digital forming system, or other systems.

[0047] The radar unit 70 having the above configuration is detachably attached to the bracket 50 (bracket body 51). Specifically, as shown in Fig. 12, the radar unit 70 is attached to the bracket 50 (bracket body 51) by screwing a screw N2 inserted into the flange portion 72 of the radar unit 70 into a screw boss 51a1 of the radar unit attachment surface 51a of the bracket 50 with the rear surface of the radar unit 70 facing the radar unit attachment surface 51a of the bracket 50.

[0048] As described above, according to this embodiment, a bracket mounting structure can be provided in which the bracket 50 to which the radar unit 70 (and the radar cover 60) is attached can be detachably attached to the outer lens 30 (the recess 32 recessed toward the lamp housing 20).

[0049] According to this bracket mounting structure, the bracket 50 can be detachably mounted to the outer lens 30 (recess 32 recessed toward the lamp housing 20) by inserting the protrusion 52 into the groove 33 (see the enlarged view in the circle C1 in FIG. 4) and fixing the extension 53 (lower end 53a) to the mounting partner (for example, the lamp housing 20). At that time, the restricting portion 34 is inserted into the fitting recess 54 and fitted therein (see FIGS. 5 and 7). As a result, the bracket 50 can be stably mounted to the outer lens 30 (recess 32) since the movement of the bracket 50 in the up, down, left and right directions is restricted. As a result, a bracket mounting structure is realized in which the position of the bracket 50 with respect to the outer lens 30 is unlikely to shift even when vibrations (mainly vibrations during vehicle running) are applied, that is, unintended movement in the up, down, left and right directions can be suppressed.

[0050] Next, a modified example will be described.

[0051] In the above embodiment, an example has been described in which the groove 33 is formed in the inner wall 32b (upper inner wall 32b1) of the recess 32, and the protrusion 52 to be inserted into the groove 33 is provided on the upper side of the bracket main body 51, but this is not limiting. For example, the groove 33 may be formed (not shown) in the inner wall 32b (inner inner wall 32b3) of the recess 32, and the protrusion 52 to be inserted into the groove 33 may be provided on the inner side of the bracket main body 51 in the vehicle width direction.

[0052] In the above embodiment, the restricting portion 34 protruding toward the bracket 50 is provided on the bottom surface 32a of the recess 32 of the outer lens 30, while the bracket main body 51 is provided with the fitting recess 54 into which the restricting portion 34 is inserted and fitted, but this is not limited to the above. Although not shown, the bracket main body 51 may be provided with the restricting portion 34 protruding toward the outer lens 30 (bottom surface 32a of the recess 32), while the bottom surface 32a of the recess 32 of the outer lens 30 may be provided with the fitting recess 54 into which the restricting portion 34 is inserted and fitted.

[0053] In the above embodiment, the groove 33 (an example of an engaged portion of the present disclosure) is provided on the inner wall 32b (upper inner wall 32b1) of the recess 32, while the protrusion 52 (an example of an engaging portion of the present disclosure) that is inserted into (engages with) the groove 33 is provided on one end side of the bracket main body 51, but this is not limited to the above. Conversely, although not shown, the protrusion 52 (an example of an engaging portion of the present disclosure) may be provided on the inner wall 32b (upper inner wall 32b1) of the recess 32, while the groove 33 (an example of an engaged portion of the present disclosure) into which the protrusion 52 is inserted (engages) may be provided on one end side of the bracket main body 51.

[0054] In the above embodiment, the restricting portions 34 are provided at two locations (see Figs. 7 and 8) on the bottom surface 32a of the recess 32 of the outer lens 30, and the fitting recesses 54 into which the restricting portions 34 are inserted and fitted are provided at two locations (see Fig. 7) on the bracket main body 51. However, the present invention is not limited to this. Although not shown, the restricting portions 34 may be provided at one or three or more locations on the bottom surface 32a of the recess 32 of the outer lens 30, and the fitting recesses 54 into which the restricting portions 34 are inserted and fitted may be provided at one or three or more locations on the bracket main body 51.

[0055] The numerical values ​​shown in the above embodiments are all examples, and it goes without saying that suitable numerical values ​​different from these can be used.

[0056] The above-described embodiments are merely examples in all respects. The present disclosure should not be construed as being limited by the description of the above-described embodiments. The present disclosure can be implemented in various other forms without departing from the spirit or main characteristics thereof. [Explanation of symbols]
