Description

Technical Field

[0001] This application generally relates to a shielding device and a camera device including the shielding device, and more specifically, to a camera device on the exterior of a vehicle and its shielding device. Background Technology

[0002] By installing cameras on the exterior of the vehicle to image the external environment, drivers can be provided with reversing images, assistance with automatic parking, and autonomous driving.

[0003] Some existing vehicle exterior camera systems include a movable shield to protect the camera from contamination or damage. When the camera is not in operation, the shield covers it in its closed position, preventing contamination or damage. When the camera is in operation, the shield moves to the open position, exposing the camera for operation. Furthermore, this movable shield can be repositioned by rotating or translating only. Utility Model Content

[0004] The inventors of this application, through long-term observation and research, discovered that rain and snow falling on the camera during rainy or snowy weather can affect the clarity of the camera's images.

[0005] To at least partially solve the above-mentioned technical problems, according to a first aspect of this application, this application provides a shielding device comprising a shielding member. The shielding member is in an extended position during rainy or snowy weather, providing shielding for a camera without affecting its operation, and returns to a retracted position during non-rainy or snowy weather. The shielding device includes a mounting base, a shielding member, and a transmission component. The mounting base has a guide portion. The shielding member is connected to the mounting base via the guide portion to move between an extended position and a retracted position under the guidance of the guide portion. The shielding member has a first engagement portion. The transmission component has a second engagement portion configured to engage with the first engagement portion. The first and second engagement portions are configured such that the shielding member translates relative to the mounting base between the extended and retracted positions under the drive of the transmission component, and allows the shielding member to flip relative to the mounting base during translation.

[0006] In some embodiments, the flipping of the shield relative to the mounting base causes the path of movement of the shield between the extended position and the retracted position to be curved in the height direction of the shielding device.

[0007] In some embodiments, one of the first and second engagement portions is a protrusion, and the other of the first and second engagement portions is a receiving groove that extends a distance along its length. The protrusion is configured to be received in the receiving groove and is movable within the receiving groove along its length.

[0008] In some embodiments, the receiving groove is a linear chute.

[0009] In some embodiments, the protrusion has a spherical surface and the receiving groove has an arc-shaped cross-section.

[0010] In some embodiments, the cross-sectional shape of the receiving groove is complementary to at least a portion of the cross-sectional shape of the protrusion passing through its center.

[0011] In some embodiments, the transmission component includes a rod having opposing first and second ends. A protrusion is disposed at the second end, and the first end is driveably engaged with a drive device such that the rod rotates when the first end is driven by the drive device, and drives the blocking member to move between the retracted position and the extended position.

[0012] In some embodiments, the transmission component includes a rod having opposing first and second ends. A receiving slot is disposed between the first and second ends, the first end being driveably engaged with a driving device such that the rod rotates when the first end is driven by the driving device, and drives the blocking member to move between the retracted position and the extended position.

[0013] In some embodiments, the blocking device includes two rods configured to move toward each other or away from each other when driven by the drive device.

[0014] In some embodiments, the blocking device includes the drive unit. The transmission component includes a gear set that connects the two rods to the drive unit respectively.

[0015] In some embodiments, the gear set includes an input gear, a first output gear, and a second output gear. The input gear engages with the drive mechanism. The first output gear meshes with the input gear and connects to a first end of one of the two levers. The second output gear meshes with the first output gear and connects to a first end of the other of the two levers.

[0016] In some embodiments, the guide includes a guide rail whose shape corresponds to the shape of the path along which the blocking member moves between the extended position and the retracted position.

[0017] In some embodiments, the mounting base includes a top cover and a base, the top cover being connected to the base, and the shielding member being housed between the top cover and the base when the shielding member is in the retracted position. The longitudinal cross-sectional shape of the top cover and the shielding member conforms to the shape of the guide rail.

[0018] In some embodiments, the vehicle-mounted device includes a vehicle-mounted camera, a vehicle-mounted lidar, a vehicle-mounted detection radar, a vehicle charging port, and a vehicle rearview mirror.

[0019] According to a second aspect of this application, a camera device is provided, comprising a blocking device according to this application and a camera. A mounting base for the blocking device defines a cavity, and the camera is disposed within the cavity of the blocking device.

[0020] This application provides a shielding device to shield the camera from rain and snow, preventing or reducing rain and snow from falling on the camera. Furthermore, the shielding device is configured such that when the shielding member translates between an extended position and a retracted position, it allows the shielding member to rotate relative to the camera, such that the path of movement of the shielding member between the extended and retracted positions can adapt to the curved shape of the mounting base cover of the shielding device.

Detailed Implementation

[0035] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although directional terms such as "front," "rear," "upper," "lower," "left," "right," "top," and "bottom" are used in this application to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be arranged in different orientations, these directional terms are for illustrative purposes only and should not be considered as limiting.

[0036] Figure 1A and Figure 1B The overall structure of a shielding device 100 according to an embodiment of this application is shown. Figure 1A This is a perspective view of the shielding device 100. Figure 1BThis is an exploded view of the blocking device 100. (See attached image.) Figure 1A and Figure 1B As shown, the blocking device 100 includes a blocking member 110, a mounting base 120, a driving device 130, and a transmission component 140. The blocking device 100 has a length direction ( Figure 1A The direction of the X-axis and the width direction shown in the figure. Figure 1A The Y-axis direction and the height direction are shown in the figure. Figure 1A (The Z-axis direction is shown in the figure).

[0037] The blocking member 110 extends a length along the length direction of the blocking device 100 and a width along the width direction of the blocking device 100. The blocking member 110 is connected to and supported by the mounting base 120. The blocking member 110 has an extended position and a retracted position. In the extended position, the blocking member 110 extends relative to the mounting base 120, and in the retracted position, the blocking member 110 retracts relative to the mounting base 120. The blocking member 110 is connected to the driving device 130 via a transmission member 140, so that under the drive of the driving device 130, the transmission member 140 drives the blocking member 110 to move relative to the mounting base 120 between the extended position and the retracted position. The blocking member 110 shown in the figure is a baffle; in other embodiments, the blocking member 110 may be in other forms.

[0038] refer to Figure 1B The structure of the mounting base 120 is described. The mounting base 120 defines a cavity 125, in which a drive unit 130 and a transmission component 140 are disposed. In one embodiment, the drive unit 130 is a motor. A camera (not shown) is disposed in the cavity 125. The base 121 has a front wall 123 disposed in the longitudinal direction of the shielding device 100, and an opening 127 is provided on the front wall 123. The camera is aligned with the opening 127, thereby exposing the camera through the opening 127 and enabling it to take pictures.

[0039] Mount 120 includes a base 121 and a top cover 122 connected to each other. When the obstruction 110 is in its extended position, the obstruction 110 extends from between the top cover 122 and the base 121, thus extending forward relative to the camera above it to provide obstruction. When the obstruction 110 is in its retracted position, the obstruction 110 is housed between the base 121 and the top cover 122 and does not extend forward relative to the camera, thus not obstructing the camera above it.

[0040] The base 121 has a pair of opposing sidewalls 124 in the width direction of the blocking device 100, each sidewall 124 having a guide rail 126 as a guide portion, the guide rail 126 extending along the length direction of the blocking device 100. A pair of side edges of the blocking member 110 in the width direction are supported on the guide rail 126. The blocking member 110 is connected to the mounting base 120 via the guide rail 126, supported by the mounting base 120, and moves along the guide rail 126. When the blocking member 110 is driven by the driving device 130, the blocking member 110 moves relative to the mounting base 120 between an extended position and a retracted position under the guidance of the guide rail 126. It should be understood that in other embodiments, only one guide rail 126 is provided on one sidewall 124. It should be understood that in other embodiments, other forms of guide portions may be provided.

[0041] The guide rail 126 is configured to have a curved shape, such that the path of the blocking member 110 moving between its extended and retracted positions under the guidance of the guide rail 126 is correspondingly curved. In the embodiment shown in the figure, the guide rail 126 is curved upward in the height direction of the blocking device 100 (see figure). Figure 6A and Figure 7A It should be understood that in other embodiments, the guide rail 126 is configured to have other curved shapes. In the embodiment shown in the figures, the longitudinal section shapes of the top cover 122 of the mounting base 120 and the shield 110 along their length directions are both arcuate, consistent with the guide rail 126 (see Figure 126). Figure 6A and Figure 7A This allows the shield 110 to move closely against the top cover 122 between the extended and retracted positions. Consequently, the space occupied by the shield 110 in the cavity 125 is minimized. It should be understood that in other embodiments, when the guide rail 126 is configured to have other curved shapes, the top cover 122 and the shield 110 may be configured to have corresponding longitudinal profile shapes. It should be understood that the shape and configuration of the mounting base 120 shown in the accompanying drawings are schematic, and in other embodiments, the mounting base 120 may be configured to have other shapes and configurations.

[0042] Figure 2 yes Figure 1B The figure shows a bottom perspective view of the shielding member 110, illustrating its structure. A receiving groove 202 is provided on the lower surface 201 of the shielding member 110 as a first engagement portion. The receiving groove 202 has a length extending in the width direction of the shielding member 110 and a width extending in the length direction of the shielding member 110. In the embodiment shown in the figure, the receiving groove 202 is a linear groove. In other embodiments, the receiving groove 202 can be constructed in other shapes, as long as its shape matches the rod 321 of the transmission member 140 described below (see figure 140). Figure 3 The movement path of ).

[0043] Figure 3 yes Figure 1B The partially exploded perspective view of the transmission component 140 shows its structure. The transmission component 140 includes a gear set 311 and two levers 321. The gear set 311 includes an input gear 312, a first output gear 313, and a second output gear 314. The input gear 312 is connected to the drive unit 130 (see...). Figure 1B The first output gear 313 engages with the input gear 312, thereby being driven by the input gear 312 to rotate in the opposite direction to the input gear 312. The second output gear 314 engages with the first output gear 313 but not with the input gear 312, thereby being driven by the first output gear 313 to rotate in the opposite direction to the first output gear 313. Alternatively, the second output gear 314 engages with both the input gear 312 and the first output gear 313, while the first output gear 313 does not engage with the input gear 312.

[0044] Two rods 321 each have a first end 322 and a second end 323 facing each other. The first ends 322 of the two rods 321 are respectively connected to the first output gear 313 and the second output gear 314, so that the two rods 321 can rotate in opposite directions to each other as the first output gear 313 and the second output gear 314 rotate, so as to move toward each other or away from each other. Each rod 321 also includes a protrusion 325 provided at the second end 323 of the rod 321 as a second engagement portion for engaging with the receiving groove 202, which is the first engagement portion, so that the transmission member 140 can drive the blocking member 110 to move between an extended position and a retracted position along the length direction of the blocking device 100. In the embodiment shown in the figure, when the driving device 130 stops driving the input gear 312, the input gear 312, the first output gear 313 and the second output gear 314 stop rotating and can maintain their current state, so that the rods 321 can remain in their current state, and the blocking member 110 can remain at any position on its movement path. Although the embodiment shown in the figure transmits power from the drive unit 130 to drive the rod 321 via the gear set 311, in other embodiments, the rod 321 can be driven in other ways, including but not limited to directly connecting the rod 321 to the corresponding drive unit so that the drive unit drives the rod 321. The figure shows two rods 321; it should be understood that in other embodiments, one or other numbers of rods 321 may be provided. Although the figure shows one receiving slot 202, in other embodiments, the same number of receiving slots as the protrusions 325 may be provided to receive the corresponding protrusions 325.

[0045] Figure 4 It is along Figure 1BThe cross-sectional view along line BB further illustrates the construction of the protrusion 325 on rod 321 and the receiving groove 202 on the shield 110, as well as their installation and engagement. The protrusion 325 is received within the receiving groove 202 of the shield 110. The shape and dimensions of the receiving groove 202 and the protrusion 325 are designed to allow the protrusion 325 to move back and forth within the receiving groove 202 along its length, but restrict its movement along the width of the receiving groove 202. This allows the two rods 321 (see...) to... Figure 3 When the first end 322 of the first end 322 rotates to bring the second end 323 together or away from each other, the blocking member 110 can be positioned on the rod 321 (see...) Figure 3 Driven by the lever 321, the shielding device 100 translates back and forth between an extended position and a retracted position along its length. The shape and size design of the receiving slot 202 and the protrusion 325 also allow the protrusion 325 and the receiving slot 202 to rotate relative to each other in the height direction of the shielding device 100, allowing the shielding member 110 to flip relative to the mounting base 120 in the height direction of the shielding device 100. This allows the shielding member 110 to rotate relative to the mounting base 120 when the shielding member 110 is on the lever 321 (see...). Figure 3 Driven by the shielding device 100, the shielding member 110 moves back and forth between the extended and retracted positions along the length of the shielding device 100, while the shielding member 110 can move along the guide rail 126 (see...). Figure 1B Under the action of ) in the height direction of the shielding device 100 relative to the mounting base 120 (see) Figure 1A The blocking member 110 rotates relative to the mounting base 120. Therefore, the movement path of the blocking member 110 between its extended and retracted positions is curved in the height direction of the blocking device 100. It should be understood that the rotation of the blocking member 110 relative to the mounting base 120 occurs around an axis passing through the protrusion 325 and parallel to the length direction of the receiving groove 202. It should be understood that since the rotation of the blocking member 110 relative to the mounting base 120 is based on the engagement of the protrusion 325 with the receiving groove 202, the rotation amplitude of the blocking member 110 relative to the mounting base 120 is arbitrary, provided that the protrusion 325 and the receiving groove 202 allow it. During the movement of the blocking member 110 between its extended and retracted positions, the rotation amplitude of the blocking member 110 can adapt to the shape of the guide rail 126, thereby allowing the blocking member 110 to obtain a movement path that matches the shape of the guide rail 126.

[0046] exist Figure 4 In the illustrated embodiment, the protrusion 325 has a spherical surface 401, and the cross-section 403 of the receiving groove 202 along its width direction is arc-shaped, thereby facilitating the movement of the protrusion 325 along the length of the receiving groove 202 and facilitating the flipping of the shield 110 relative to the mounting base 120. Figure 4In the illustrated embodiment, the shape of the cross-section 403 of the receiving groove 202 is complementary to at least a portion of the cross-sectional shape of the protrusion 325 passing through its center (the portion received by the receiving groove 202), which makes the engagement of the protrusion 325 and the receiving groove 202 more reliable, and the protrusion 325 less likely to detach from the receiving groove 202. In other embodiments, the protrusion 325 and the receiving groove 202 may be configured in other shapes.

Figure 6A When the shielding member 110 is in the middle position, Figure 1A The shielding device 100 shown along Figure 1A Sectional view of line AA in the middle. Figure 6B The shielding device 100 is shown in Figure 6A The positional relationship between the transmission component 140 and the blocking component 110 in the state shown. Figure 7A This shows the shield 110 in the extended position. Figure 1A The shielding device 100 shown along Figure 1A Sectional view of line AA in the middle. Figure 7B The shielding device 100 is shown in Figure 7A The positional relationship between the transmission component 140 and the blocking component 110 in the state shown.

[0048] Figure 5A and Figure 5B In the shown configuration, the obstruction 110 is in the retracted position. The obstruction 110 is housed between the top cover 122 and the base 121, and does not extend forward beyond the camera (not shown), thus not obstructing the camera from above. Both levers 321 are in the open position, so the protrusions 325 on each lever 321 are located at opposite ends of the receiving slot 202.

[0049] from Figure 5A and Figures 5B to 6A and Figure 6B The drive unit 130 drives the input gear 312 (see...) Figure 3The two rods 321 are driven by the drive device 130 to close together, and the protrusions 325 of the two rods 321 move along the length of the receiving groove 202 toward the center of the receiving groove 202. The two rods 321 push the blocking member 110 forward along the length direction of the blocking device 100, so that the blocking member 110 extends relative to the mounting base 120. During this movement, the blocking member 110 is driven by the two rods 321 to translate forward relative to the mounting base 120 under the guidance of the guide rail 126, and at the same time, it is flipped relative to the mounting base 120 under the action of the guide rail 126.

[0050] When arriving as Figure 6A and Figure 6B In the indicated state, the two rods 321 are driven to rotate to a partially closed state, and the shielding member 110 extends forward a certain distance relative to the mounting base 120, reaching a middle position. In this middle position, the shielding member 110 extends forward above the camera (not shown) by more than one length. Thus, the shielding member 110 provides shielding for the camera above it, preventing or minimizing the impact of rain, snow, etc., on the camera without affecting its recording capabilities. When the shielding member 110 is in this middle position, if the driving device 130 stops driving the rods 321, the rods 321 can remain in this position. Figure 6B The partially closed state is shown, and correspondingly, the shielding member 110 remains in the closed state. Figure 6A The middle position shown.

[0051] from Figure 6A and Figures 6B to 7A and Figure 7B Driven by the drive device 130, the two rods 321 continue to rotate to converge towards each other, and the protrusions 325 of the rods 321 further move along the length of the receiving groove 202 toward the center of the receiving groove 202. The two rods 321 continue to push the blocking member 110 forward along the length of the blocking device 100, causing the blocking member 110 to extend further relative to the mounting base 120. During this movement, the blocking member 110 is driven by the two rods 321 to translate forward relative to the mounting base 120 under the guidance of the guide rail 126, and simultaneously flips relative to the mounting base 120 under the action of the guide rail 126.

[0052] When arriving as Figure 7A and Figure 7B In the indicated state, the two rods 321 are in the closed position. The obstruction member 110 extends forward a greater distance relative to the mounting base 120, reaching the extended position. In this extended position, the obstruction member 110 extends forward above the camera by a greater length than the camera itself, thus providing a larger area of ​​obstruction above the camera without affecting its recording.

[0053] It should be understood that when it is necessary to return the blocking member 110 from the extended position to the retracted position, the drive unit 130 drives the input gear 312 (see...) Figure 3 Rotate in the opposite direction to drive the two rods 321 away from each other and open them apart, i.e., according to the direction from which the rods 321 are opened. Figure 7A and Figures 7B to 5A and Figure 5B The sequence control lever 321 and the blocking member 110 move.

[0054] It should be understood that, Figure 6A and Figure 6B The partially closed state of the lever 321 and the intermediate position of the blocking member 110 shown are schematic; the lever 321 can be driven to and maintained at this position. Figure 5B The open state shown and Figure 7B The shown closed state can be partially closed, and correspondingly, the blocking member 110 can be driven to and maintained in a closed state. Figure 5A The retraction position shown and Figure 7A Any intermediate position between the shown extension positions.

[0055] Figure 8 The shielding member 810 and the transmission member 840 are in a shielding device according to another embodiment of this application. Figure 8 The shielding component 810 and Figure 1B The shielding component 110 and Figure 8 The transmission component 840 and Figure 1B The only difference in the transmission component 140 is the placement of the protrusion and the receiving groove. For example... Figure 8 As shown, the lower surface of the blocking member 810 is provided with two protrusions 825 similar to protrusions 325, and each of the two rods 821 is provided with a receiving groove 802 similar to the receiving groove 202 between its two ends. The two receiving grooves 802 are respectively used to receive the two protrusions 825 and cooperate with the protrusions 825, so that when the rods 821 are driven to rotate, they can drive the blocking member 810 to move between the extended position and the retracted position in a manner similar to that of the blocking member 110.

[0056] Although in the embodiments shown in this application, receiving grooves and protrusions are respectively provided on the shielding member and the transmission member as the first and second joints, in other embodiments, other forms of the first and second joints may be provided so that the shielding member can be rotated relative to the mounting base while being translated relative to the mounting base under the drive of the transmission member.

[0057] The inventors of this application discovered that the imaging effect of cameras used on the exterior of vehicles is affected by rain and snow. By using the shielding device according to this application, a shield can be driven to extend relative to the mounting base during rain and snow. Since the camera is located in the cavity defined by the mounting base, when the shield extends relative to the mounting base, the shield extends above the camera, beyond the camera, shielding the camera from rain and snow and preventing or reducing rain and snow falling on the camera. This avoids or reduces the impact of rain and snow on the camera's imaging effect. In non-rainy / snowy weather, the shield can be driven and held in its retracted position, so that the shield does not affect the overall shape of the vehicle. In the shielding device according to this application, the shield can be driven and held to any extension length. Therefore, the shielding device according to this application can adjust the extension length of the shield according to the intensity of rain and snow.

[0058] In the shielding device according to this application, the shielding member is capable of moving between an extended position and a retracted position along a curved path in the height direction of the shielding device. This allows the top cover of the shielding device to be constructed with a corresponding curved shape, thus enabling the top cover shape to meet the requirements of the usage environment. In the embodiments described in this application, the top cover of the shielding device is designed to have an arcuate shape to adapt to the arcuate shape of the vehicle's exterior sheet metal, thereby achieving good overall vehicle appearance.

[0059] In the shielding device according to this application, since the movement path of the shielding member can be consistent with the shape of the top cover of the shielding device, and the cross-sectional shape of the shielding member and the top cover along the movement path of the shielding member are set to be consistent, the shielding member can move closely against the top cover. Therefore, the shielding member occupies minimally the cavity space defined by the mounting base of the shielding device. Thus, the shielding device according to this application has a compact structure.

[0060] In the blocking device according to this application, since the flipping of the blocking member is based on the cooperation between the protrusion and the receiving groove, the flipping range of the blocking member is arbitrary, provided that the protrusion and the receiving groove allow it. Therefore, the movement path of the blocking member can adapt to the shape of the guide portion. By designing the shape of the guide portion, the blocking device according to this application can be applied to various occasions where there are different requirements for the movement path of the blocking member.

[0061] Although the blocking device described herein is used for vehicle cameras, it should be understood that the camera device described herein can be used for other vehicle devices that need to be blocked, including but not limited to vehicle lidar, vehicle detection radar, vehicle charging port and vehicle rearview mirror.
