Description

[Technical field]

[0001] The present invention relates to a vehicle visual confirmation device equipped with an electric storage unit such as a vehicle side mirror, and which has improved drainage performance for a movable portion of the electric storage unit. [Background technology]

[0002] Conventionally, it has been known that vehicle visual confirmation devices installed on the side of a vehicle, such as side mirrors, are configured to rotate using an electric storage unit and be folded on the side of the vehicle when not in use.

[0003] This electric storage unit is configured so that the torque of an electric motor provided inside the case is used by a drive mechanism to rotate a shaft on the vehicle side.

[0004] However, this electric storage unit is provided with a clutch mechanism to allow the electric motor, drive mechanism, etc. to rotate freely around the shaft on the vehicle side, so that they do not become damaged if the vehicle visualization device receives an external impact, for example.

[0005] This clutch mechanism is configured such that, when a certain load is applied to the vehicle visualizing device, the case etc. is lifted against the spring force, causing the vehicle visualizing device to rotate around the shaft.

[0006] As a result, when the case or the like is lifted by the clutch mechanism, a gap is created in the moving part between the case and the shaft of the electric storage unit, and there is a risk that rainwater or the like may enter the moving part through this gap.

[0007] Therefore, in the vehicle visualization device of Patent Document 1 below, a hanging wall 30C extending downward is provided on the case side of the electric storage unit, and a vertical wall 64 is provided on the shaft side (stand side 22) that overlaps with the hanging wall 30C radially inward, so that no gaps are created even if the case etc. are lifted by the action of the clutch mechanism.

[0008] With this configuration, there is no gap between the case and shaft of the electric storage unit, eliminating the risk of rainwater or the like entering the moving parts. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2007-91075 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, since the vehicle visual confirmation device is installed outside the vehicle cabin, if water or moisture remains inside the case or the like for a long period of time, deterioration such as rust will occur. Therefore, the vehicle visual confirmation device is required to have not only waterproof performance but also improved drainage performance.

[0011] In the case of the vehicle visual confirmation device of the above-mentioned Patent Document 1, the provision of the hanging wall 30C and the standing wall 64 certainly eliminates the gap between the shaft and the case, and improves waterproof performance against rainwater and the like from the outside. However, since both the hanging wall 30C and the standing wall 64 are provided around the entire circumference of the shaft (see FIG. 2 of Patent Document 1), even if the standing wall 64 If water or water droplets penetrate into the inside of the diameter, the water will remain inside for a long period of time and will not be drained to the outside, causing problems such as deterioration due to rust.

[0012] The present invention has been made in consideration of these points, and its purpose is to provide a vehicle visualization device equipped with an electric storage unit, which is configured so that no gaps are created in the moving parts between the case and the shaft even when the case or the like is lifted by the clutch mechanism, and which, if water or the like does enter the moving parts, is able to drain the water or the like to the outside, thereby preventing deterioration such as rust. [Means for solving the problem]

[0013] In order to achieve this object, the present invention provides a vehicle visual confirmation device that is installed on the side of a vehicle and includes an electric storage unit. The device has a hanging wall that extends downward on the case of the electric storage unit, and a standing wall that overlaps with the hanging wall on the radially inner side of the shaft on the vehicle body side. The standing wall is provided with a vertical wall on the radially inner side. water The device is characterized by having a drain outlet for draining the water to the outside.

[0015] According to this configuration, the case is provided with a downwardly extending hanging wall, and the shaft is provided with an upwardly extending standing wall overlapping the radially inward side of the hanging wall, so that no gap is generated between the case and the shaft even if the case is lifted by the clutch mechanism. water By providing a drainage outlet to drain the water to the outside, water Even if water accumulates, it will be drained outside.

[0016] Therefore, while the clutch mechanism ensures waterproof performance when the case is lifted, the inside diameter of the vertical wall water Since the water is also discharged to the outside through the drain, the drainage performance can also be improved.

[0017] The drainage outlet in the vertical wall may be a cutout in part of the vertical wall, a hole in part of the vertical wall, or a labyrinth-shaped outlet formed by staggering vertical walls. water Any structure that can drain water to the outside is acceptable.

[0018] Furthermore, the number of drainage holes is not limited to one, but may be multiple.

[0019] A second aspect of the present invention is characterized in that the drainage port provided in the standing wall is formed at a position on the inside of the vehicle.

[0020] According to this configuration, by forming the drain outlet in the vertical wall at a position on the inside of the vehicle, the drain outlet is not affected even if a high-pressure water flow acts from the outside of the vehicle during a car wash, etc.

[0021] Therefore, even if water is sprayed on the vehicle visual confirmation device from the outside of the vehicle during a car wash, the water will not flow to the inside of the vertical wall. water can be prevented from entering.

[0022] Therefore, the drainage performance of the drain outlet can be improved without compromising the convenience of washing the car, etc.

[0023] In the third invention, a drain outlet is provided on the radially inner side of the drain outlet. water It is characterized by the formation of a drainage groove that concentrates water.

[0024] According to this configuration, on the radially inner side of the drain port, water By forming a drainage ditch that concentrates the water, water This allows the water to be reliably concentrated and guided to the drain.

[0025] Therefore, the inside diameter of the vertical wall water This ensures that the water is guided to the drain outlet, thereby improving the drainage performance of the drain outlet.

[0026] This improves the drainage performance of the drain outlet, thereby enabling the drainage performance to be improved while maintaining the waterproof performance. Effect of the Invention

[0027] As described above, according to the present invention, the waterproof performance when the case or the like is raised by the clutch mechanism is ensured, while the radially inward side of the vertical wall is prevented from being damaged. water Since the water is also discharged to the outside through the drain, the drainage performance can also be improved.

[0028] Therefore, in a vehicle visual confirmation device equipped with an electric storage unit, even if the case or the like is lifted by the clutch mechanism, a gap is not generated in the movable part between the case and the shaft. water In the event of an intrusion, water This allows the water to be drained outside to prevent deterioration such as rust.

[0030] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its application, or its uses.

[0031] (Embodiment 1) First, referring to FIG. 1 to FIG. 4, a vehicle visual display device equipped with an electric storage unit according to the first embodiment will be described. The structure of the device will be explained below. Note that the direction of each arrow in each figure indicates each direction.

[0032] The vehicle visual confirmation device 1 of this embodiment is, for example, a side mirror device 1 erected on a side door 2 of a vehicle as shown in Fig. 1, and this side mirror device 1 is provided so as to protrude from the vehicle to the side (right side) of the vehicle. This side mirror device 1 includes a side mirror body 4 provided with a mirror surface 3, and a mirror base 5, and is erected on the side door 2 by fixing the mirror base 5 to the side door 2 with a fixing bolt 6. Although not shown, a side mirror device 1 is also erected on the side door on the opposite side of the vehicle so as to protrude from the vehicle to the side (left side).

[0033] In addition, the side mirror body 4 is mounted on a mirror base 5 via an electric storage unit U built into the side mirror body 4, and is configured to rotate between an unfolded state shown by a solid line and a folded state shown by a dashed dotted line by operation of the electric storage unit U.

[0034] 2 is a plan view of the electric storage unit U as seen from above, FIG. 3 is a rear view of the electric storage unit U as seen from the rear of the vehicle, and FIG. 4 is an exploded perspective view of the electric storage unit U.

[0035] The aforementioned electric storage unit U comprises a shaft 10 fixed to the mirror base 5, a case 20 that rotates around the shaft 10, a cover 30 that covers the internal space of the case 20 at the top of the case 20, and a holder 40 inside the case 20 that divides the internal space into upper and lower sections.

[0036] The aforementioned shaft 10 has a fastening fixing portion 11 at its lower portion which is bolted to the mirror base 5, a support receiving portion 12 at its middle portion which supports the case 20 etc., and a shaft main body portion 13 at its upper portion which extends upward and serves as the center of rotation of the case 20 etc.

[0037] The aforementioned case 20 comprises a case body 21 which is an irregular box-shaped body with a hollow interior and is open at the top, three lower casing fixing portions 22... provided respectively at the lower front, lower rear and lower lateral portions of the case body 21, two side casing fixing portions 23, 23 provided at the upper and lower positions on the vehicle sides of the case body 21, and a number of cover engagement portions 24... provided around the upper part of the case body 21.

[0038] The aforementioned cover 30 comprises a roughly lid-shaped cover main body 31 located above the case 20, a circular opening-shaped shaft receiving portion 32 supporting the upper end of the shaft 10 on the vehicle inner side of the cover main body 21, a connection port 33 for connecting a power harness (not shown) on the vehicle lateral side (right side) of the cover main body 30, and a plurality of case engagement portions 34... that engage with cover locking portions 24... of the case 20 around the periphery of the cover main body 30.

[0039] The holder 40 is disposed in the internal space of the case 20 and includes a substantially rectangular motor holding portion 41 that surrounds and holds the electric motor M, and a horizontally extending flat plate-like partition portion 42 that divides the internal space of the case 20 into upper and lower portions. The holder 40 is also provided with a board support portion 43 that supports a circuit board B that controls the rotational drive state of the electric motor M. The partition portion 42 is also provided with a circular opening-shaped shaft holding portion 44 that holds the upper end of the shaft 10. The holder 40 is fixed to the case 20 from above by three screw members 45... at its periphery.

[0040] On the other hand, a plate shaft 51, a shaft washer 52, and a plate case 53 are attached to the above-mentioned shaft 10 above the support receiving portion 12 in this order from below. Of these, the plate shaft 51 is fixed to the support receiving portion 12 of the shaft 10, and the plate case 53 is fixed to the bottom surface of the case 20, and the plate shaft 51 and the plate case 53 are configured to define the rotation range of the case 20, i.e., the electric storage unit U. In addition, the shaft washer 52 is used to reduce frictional resistance between the case 20 and the shaft 10.

[0041] Furthermore, after being assembled into the case 20, the shaft 10 is assembled with a case washer 61, a sun gear 62, an upper clutch 63, a spring 64, and a spring stopper 65 in this order from the bottom up. The case washer 61 is located between the sun gear 62 and the case 20 to reduce frictional resistance between the sun gear 62 and the case 20.

[0042] The sun gear 62 described above is configured to mesh with a drive worm 71 described below and receive a rotational driving force from the electric motor M, causing the case 20 to rotate around the shaft 10. However, the sun gear 62 is not fixed to the shaft 10, and is loosely fitted relative to the shaft 10.

[0043] The aforementioned upper clutch 63 has a plurality of clutch receiving portions 63a... on its underside that engage with a plurality of clutch protrusions 62a... provided on the inner circumference of the sun gear 62, and has a plurality of convex ridge portions 63b... on its inner surface that engage with a plurality of concave groove portions 13a... provided in the shaft main body portion 13 of the shaft 10.

[0044] The spring 64 described above is made up of a spiral coil spring member, and applies a downward biasing force to the lower upper clutch 63.

[0045] The aforementioned spring stopper 65 is fixed to the shaft body 13 by fitting the engagement portion 65a provided on the inner circumference into an annular locking recess 13b formed in the shaft body 13 of the shaft 10, thereby preventing the spring 64 from falling out of the shaft body 13.

[0046] With the upper clutch 63, spring 64, and spring stopper 65 configured in this manner, a force is applied to the upper clutch 63 to push the sun gear 62 downward, and the sun gear 62 is fixed so as to be integral with the shaft 10 via the upper clutch 63.

[0047] In this manner, the clutch mechanism of the electric storage unit U is configured. Since the clutch mechanism is configured in this manner, under normal circumstances, the sun gear 62 and the shaft 10 are integrated, and when the sun gear 62 receives a rotational driving force from the electric motor M, the case 20 and the like rotate about the shaft 10, and the door mirror body 4 rotates between the unfolded state and the folded state, but in an abnormal situation in which the side mirror body 4 receives an impact or the like, the clutch protrusion 62a of the sun gear 62 pushes up the upper clutch 63, and the clutch is released, so that the sun gear 62 and the shaft 10 are separated, and the case 20 and the like rotate about the shaft 10, and the door mirror body 4 rotates.

[0048] In this way, in the event of an abnormality such as an impact on the side mirror body 4, the sun gear 62 and the shaft 10 can be separated, thereby preventing failure or damage to the electric motor M and the drive mechanism K described below.

[0049] Next, the structure of the drive mechanism K of the electric storage unit U of the first embodiment will be described with reference to FIGS.

[0050] As shown in Fig. 5, the electric motor M held by the motor holding portion 41 of the holder 40 is disposed so that the motor shaft Ma extends downward. A cylindrical worm 72 is fitted into the motor shaft Ma, and a disk-shaped worm wheel 73 meshes with the worm 72 as shown in Fig. 7. The aforementioned drive worm 71 is provided coaxially with the worm wheel 73 and is configured to rotate integrally with the worm wheel 73. The drive worm 71 is configured to mesh with the aforementioned sun gear 62.

[0051] That is, as shown in Figure 6, the drive mechanism K is configured to transmit the rotational driving force of the motor shaft Ma of the electric motor M, which extends in the vertical direction, to the sun gear 62 via the shaft of the drive worm 71, which is arranged in the horizontal direction and diagonally forward.

[0052] The shaft of this drive worm 71 has shaft portions 71a, 71a at both ends both of which are supported by bearing portions 25, 25 provided in the case 20, and is firmly supported by the case 20 in a double-supported manner.

[0053] Since the drive mechanism K of the electric storage unit U is configured in this manner, the drive worm 71 and the like rotate around the sun gear 62 in accordance with the rotation direction of the electric motor M, thereby rotating the case 20. As the case 20 rotates in this manner, the side mirror body 4 fixed to the case 20 rotates between the unfolded position and the folded position.

[0054] Next, the structure of the shaft 10 of the first embodiment will be described in detail with reference to FIGS.

[0055] As mentioned above, the shaft 10 is composed of, from the bottom, the fastening fixed portion 11, the support receiving portion 12, and the shaft main body portion 13, of which the upper surface of the support receiving portion 12 is formed with a circular support base surface 14 for supporting the case 20, etc.

[0056] On this support base surface 14, an upwardly extending standing wall 15 is formed in an annular shape centered on the shaft main body 13. The height of the standing wall 15 is set to a height that will prevent a gap from occurring between the shaft 10 and the case 20 in the event of an abnormality, such as when the side mirror main body 4 receives an impact or the like, the upper clutch 63 is pushed up, and the case 20, etc., is lifted, as will be described later.

[0057] The plate shaft 51 is placed on the support base surface 14 on the radially inner side of the standing wall 13. As described above, the plate shaft 51 has a pair of raised portions 51a, 51a (see FIG. 4) formed at positions of approximately 135° and approximately 315°, with the vehicle inner side position being 0°, in order to determine the rotation range of the electric storage unit. The two insertion pieces 51b, 51b of the plate shaft 51 are configured to engage with two locking recesses 14a, 14a formed on the support base surface 14 so that the position of the plate shaft 51 does not shift.

[0058] Further, a drainage port 16 is provided by cutting out a part of the standing wall 15 at a position on the inside of the vehicle of the above-mentioned standing wall 15. As will be described later, this drainage port 16 is provided to drain water or water droplets that have entered the radially inner side of the standing wall 15 to the outside.

[0059] A drain groove 17 is formed on the support base surface 14 on the radially inner side of the drain port 16. By providing this drain groove 17, water and water droplets that fall onto the support base surface 14 on the radially inner side of the standing wall 15 can be concentrated in the drain groove 17, and the water can be smoothly guided to the drain port 16.

[0060] Next, the functions of the vertical wall 15, the drain port 16, the drain groove 17, etc. of the shaft 10 will be described with reference to Figures 11 and 12.

[0061] 11, a hanging wall 27 extending downward from the case 20 is provided on the radially outer side of the standing wall 15 of the shaft 10 so as to overlap with the radially outer side of the standing wall 15. This hanging wall 27 is also formed in an annular shape with the shaft main body 13 as its center.

[0062] The length La of this hanging wall 27 is formed long enough to hide all of the movable parts between the case 20 and the shaft 10 under normal conditions when the cylindrical seat portion 28 of the case 20 is placed on the support surface 14 of the shaft 10 via the shaft washer 52.

[0063] For this reason, normally, the movable parts between the case 20 and the shaft 10, i.e., the plate shaft 51, shaft washer 52, and plate case 53, which are present in the space S above the support base surface 14 of the shaft 10, are prevented from being exposed to the outside.

[0064] On the other hand, as shown in FIG. 12, in the event of an abnormality such as when the side mirror body 4 (see FIG. 1) receives an impact or the like, the case 20 is pushed upward by the action of a clutch mechanism such as the upper clutch 63 (see FIG. 4) as described above. However, since a vertical wall 15 is formed on the shaft 10 and the height Ha of the vertical wall 15 is made higher than the amount of upward movement h, the movable part (upper space S) between the case 20 and the shaft 10 is prevented from being exposed to the outside.

[0065] For this reason, even if the case 20 is lifted upward in the event of an abnormality such as when the side mirror main body 4 receives an impact, water or the like will not enter the movable part (upper space S) between the case 20 and the shaft 10 from the outside, thereby improving waterproofing.

[0066] However, due to the presence of the standing wall 15, if water or the like should enter the movable portion (upper space S) between the case 20 and the shaft 10 for some reason, the water or the like cannot be drained to the outside. Therefore, in this embodiment 1, the above-mentioned drain port 16 and drain groove 17 are provided.

[0067] Specifically, as shown by the arrow in Fig. 11, when water W enters the space S above the support base surface 14 of the shaft 10, the water W is collected by the drain groove 17 and guided radially outward. Then, the water W is drained to the outside (radially outward) by the drain port 16.

[0068] In this way, by providing the drain port 16 and the drain groove 17, the water W that has entered the movable part (upper space S) between the case 20 and the shaft 10 can be drained to the outside. In this way, by draining the water W that has entered the movable part (upper space S) to the outside, it is possible to prevent the occurrence of rust and the like on the members present in the upper space S, such as the plate shaft 51, the shaft washer 52, and the plate case 53.

[0069] As described above, in this embodiment, the side mirror device 1 is provided with an electric storage unit U that is installed on the side of the vehicle and is configured to rotate between an unfolded position and a folded position, and the electric storage unit U includes a case 20 with a clutch mechanism therein, and a shaft 10 fixed to the vehicle side, and the clutch mechanism is configured to lift the case 20 and rotate around the shaft 10 when a predetermined load is applied, and the case 20 is provided with a downwardly extending hanging wall 27 around the entire circumference of the shaft 10, and the shaft 10 is provided with an upwardly extending standing wall 15 that is overlapped on the radially inward side of the hanging wall 27, and the standing wall 15 is provided with a drainage port 16 for draining water and the like on the radially inward side to the outside.

[0070] As a result, even if the clutch mechanism causes the case 20 and the like to be lifted, no gap is created between the case 20 and the shaft 10. Also, by providing the vertical wall 15 of the shaft 10 with a drain port 16 for draining water and the like on the radially inward side (upper space S) to the outside, even if water and the like accumulates in the upper space S on the radially inward side of the vertical wall 15, it will be drained to the outside.

[0071] Therefore, while ensuring waterproof performance when the case 20 etc. is lifted by the clutch mechanism, water etc. in the upper space S on the radially inner side of the vertical wall 15 is also drained to the outside through the drain outlet 16, improving drainage performance.

[0072] Therefore, in the side mirror device 1 equipped with the electric storage unit U, even if the case 20 etc. is lifted by the clutch mechanism, the configuration is such that no gap occurs in the movable part between the case 20 and the shaft 10. However, if water etc. does enter the movable part (upper space S), it can be drained to the outside to prevent deterioration such as rust.

[0073] In this embodiment, the drainage port 16 provided in the standing wall 15 is formed at a position on the inside of the vehicle.

[0074] This prevents the drain outlet 16 from being affected even if a high-pressure water flow acts from the outside of the vehicle during a car wash or the like.

[0075] Therefore, even if water is sprayed on the side mirror device 1 from the outside of the vehicle during a car wash or the like, the water can be prevented from entering the inside of the standing wall 15 (the upper space S).

[0076] Therefore, the drainage performance of the drain outlet 16 can be improved without impairing the convenience of washing a car, etc.

[0077] In this embodiment, a drain groove 17 for concentrating water or the like at the drain port 16 is formed on the radially inner side of the drain port 16 .

[0078] This makes it possible for water or the like on the radially inner side (upper space S) of the standing wall 15 to be reliably concentrated and guided to the drain outlet 16.

[0079] Therefore, water or the like on the radially inner side (upper space S) of the standing wall 15 is reliably guided to the drain port 16, and the drainage performance of the drain port 16 can be improved.

[0080] This further improves the drainage performance of the drain outlet 16, thereby enabling the drainage performance to be improved while maintaining the waterproof performance.

[0081] (Other embodiments) Next, other embodiments will be described.

[0082] First, in the above-described embodiment, the drain outlet 16 is formed by cutting out a portion of the vertical wall 15, but the structure of the drain outlet is not limited to this structure, and any structure that can drain water to the outside may be used, such as a hole opened in part of the vertical wall, or a labyrinth shape formed by staggering vertical walls, etc.

[0083] Furthermore, the number of drainage holes is not limited to one, but may be multiple.

[0084] Furthermore, the visual confirmation structure of the vehicle visual confirmation device is not limited to the mirror of the above embodiment. Any device that can check the rear of the vehicle, such as a camera, may be used. [Industrial Applicability]
