Abstract

This invention discloses a camera system and a vehicle, relating to the fields of camera systems and automobiles. The system includes: a camera support arm rotatably connected to a support via a bushing, the camera support arm being rotatable around the bushing; and an elastic reset component disposed between the support and the camera support arm. When the camera support arm rotates from its initial position around the bushing, the elastic reset component applies a force opposite to the direction of rotation to the camera support arm until the camera support arm returns to its initial position. In summary, this application, by incorporating an elastic reset component between the support and the camera support arm, automatically addresses the phenomenon of the camera support arm rotating due to an external collision. This ensures that the rearview camera used for intelligent driving can rotate after a collision to protect the system from damage, and prevents the intelligent driving system from malfunctioning due to the camera angle shift caused by the bracket rotation, thus avoiding any compromise to driving safety.

Description

Technical Field

[0001] This invention relates to the field of automotive exterior technology, specifically to a camera system and an automobile. Background Technology

[0002] As in-vehicle devices become increasingly intelligent, more and more devices operate based on cameras as input signals. Examples include the now ubiquitous reversing cameras and the 360-degree panoramic cameras, whose installation rate is rising year by year, which form part of driver assistance systems. High-end models also utilize intelligent camera systems such as collision avoidance warning systems and autonomous driving systems. All these systems rely on images captured by cameras for subsequent processing.

[0003] However, when a vehicle is in motion, the intelligent rearview camera is easily damaged by collisions with foreign objects, causing it to malfunction. Related technologies incorporate a rotating bracket within the camera system. After a collision, the bracket rotates to protect the system from damage. However, this rotation causes a shift in the camera angle, rendering the intelligent driving system inoperable and jeopardizing driving safety. The driver is then forced to either disable the intelligent driving system or manually reset the bracket after stopping the vehicle before continuing to drive. Summary of the Invention

[0004] To address the problem in existing camera systems where the rotatable bracket cannot automatically return to its initial state after an external impact, causing camera malfunction and forcing passengers to stop and manually adjust it, this application provides a camera system comprising: a bracket, a camera support arm, and an elastic reset assembly; wherein...

[0005] A camera support arm is rotatably connected to the support via a bushing, and the camera support arm can rotate around the bushing.

[0006] A resilient reset assembly is disposed between the support and the camera support arm; wherein...

[0007] When the camera support arm rotates around the bushing from its initial position, the elastic reset component applies a force to the camera support arm in the opposite direction of its rotation until the camera support arm returns to its initial position.

[0008] In some embodiments, it also includes:

[0009] The monitoring unit is used to monitor the position information of the camera support arm;

[0010] The elastic reset assembly includes a locking part and a reset part, both of which are disposed between the support and the camera support arm. The reset part is signal-connected to the monitoring unit.

[0011] When the rotational stroke of the camera support arm around the bushing from its initial position is within a preset threshold, the locking part applies a locking force to the camera support arm to keep the camera support arm in its initial position.

[0012] When the monitoring unit detects that the rotational stroke of the camera support arm around the bushing from the initial position exceeds a preset threshold, the locking function of the locking part fails, and the monitoring unit controls the reset part to apply a force to the camera support arm until the camera support arm rotates back to the initial position.

[0013] In some embodiments, the locking part is a compression spring;

[0014] The bushing has a first flange at one end near the support, and a second flange at the other end away from the support. The second flange is attached to the side of the camera support arm away from the support, and a compression spring is provided between the first flange and the support.

[0015] When the camera support arm rotates around the bushing from its initial position, the camera support arm drives the bushing to move through the second flange, so that the first flange presses against the compression spring.

[0016] In some embodiments, the first contact surface between the camera support arm and the support is provided with a plurality of grooves, and the inner wall surface of the groove is a slope.

[0017] The support has multiple protrusions, each corresponding to a groove; wherein...

[0018] When the rotational stroke of the camera support arm around the bushing from its initial position is within a preset threshold, the first flange presses against the compression spring, and the protrusion moves along the inner wall towards the opening of the groove.

[0019] When the rotational stroke of the camera support arm around the bushing from its initial position exceeds a preset threshold, the protrusion moves along the inner wall surface through the opening of the groove into another adjacent groove, and the compression spring drives the protrusion to move towards the bottom of the groove where it is located.

[0020] In some embodiments, the reset unit includes:

[0021] A torsion spring, the two ends of which are connected to the support and the camera support arm respectively, is used to apply a rotational force to the camera support arm as it rotates;

[0022] A limiting unit is disposed between the first flange and the support, and the limiting unit is signal-connected to the monitoring unit.

[0023] When the monitoring unit detects that the rotational travel of the camera support arm from its initial position around the bushing exceeds a preset threshold, the monitoring unit controls the limiting unit to press the locking part to separate the compression spring from the bushing, so that the rotational force applied by the torsion spring is sufficient to drive the camera support arm back to its initial position.

[0024] In some embodiments, the limiting unit includes:

[0025] The free end is attached to the support and is located between the support and the compression spring;

[0026] An electromagnetic end is attached to the first flange. The electromagnetic end is connected to the monitoring unit via a signal. The electromagnetic end is used to drive the free end to move toward the electromagnetic end to press the locking part.

[0027] In some embodiments, the first contact surface between the camera support arm and the support is annular, the first contact surface has a through hole in the middle for the bushing to pass through, and a plurality of the groove portions are arranged circumferentially along the first contact surface.

[0028] In some embodiments, the support is used to connect to the vehicle body sheet metal, and the support is provided with a sealing gasket located between the support and the vehicle body sheet metal.

[0029] In some embodiments, the camera support arm is provided with a cover, which snaps onto the camera support arm to form a mounting cavity for mounting the camera between the two.

[0030] On the other hand, this application provides a car, characterized in that it includes: a camera system as described above.

[0031] In summary, this application incorporates an elastic reset component between the bracket and the camera support arm to automatically address the rotation of the camera support arm due to an external collision. This ensures that the rearview camera used in intelligent driving can rotate after a collision to protect the system from damage, and prevents the intelligent driving system from malfunctioning due to a shift in the camera angle caused by bracket rotation, thus ensuring driving safety. Furthermore, to address the issue of excessive impact force on the camera support arm causing the conventional reset component to fail, this application employs a monitoring unit to monitor the position of the camera support arm in real time. If excessive rotation occurs that cannot be reversed, the monitoring unit electronically controls the camera support arm to return to its initial position. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Addressing the problem in existing camera systems where the rotatable bracket cannot automatically return to its initial state after being subjected to an external impact, resulting in camera malfunction and forcing passengers to stop and manually adjust the camera, this application provides a camera system comprising: a support 1, a camera support arm 2, and an elastic reset assembly; wherein,

[0042] A camera support arm 2 is rotatably connected to the support 1 via a bushing 3, and the camera support arm 2 can rotate around the bushing 3. An elastic reset assembly is disposed between the support 1 and the camera support arm 2; wherein...

[0043] When the camera support arm 2 rotates around the bushing 3 from its initial position, the elastic reset component applies a force to the camera support arm 2 in the opposite direction of its rotation until the camera support arm 2 returns to its initial position.

[0044] Understandably, in the camera system of this application, when the camera support arm 2 rotates due to an external impact, the elastic reset component can automatically reset the camera support arm 2. In this way, passengers do not need to stop the vehicle to manually adjust the camera support arm 2.

[0045] In some specific embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the camera system of this application also includes a monitoring unit, which is used to monitor the position information of the camera support arm 2.

[0046] Furthermore, the elastic reset assembly includes a locking part 4 and a reset part 5, both of which are disposed between the support 1 and the camera support arm 2. The reset part 5 is signal-connected to the monitoring unit; wherein,

[0047] When the rotational stroke of the camera support arm 2 around the bushing 3 from its initial position is within a preset threshold, the locking part 4 applies a locking force to the camera support arm 2 to keep the camera support arm 2 in its initial position.

[0048] When the monitoring unit detects that the rotational stroke of the camera support arm 2 around the bushing 3 from the initial position exceeds a preset threshold, the locking function of the locking part 4 fails, and the monitoring unit controls the reset part 5 to apply force to the camera support arm 2 until the camera support arm 2 rotates back to the initial position.

[0049] It should be noted that although both the locking part 4 and the reset part 5 are used to drive the camera support arm 2 back to its initial position after being impacted, their functions are not the same. This is because, in actual testing, the applicant found that the camera support arm 2 experiences both small and large impacts. When the impact force is small, the rotational displacement of the camera support arm 2 is small. The monitoring unit typically judges this through image detection. However, the system's monitoring of this rotational displacement change has issues of missed and false detections. If the camera support arm 2 does not remain in its initial position, it can easily affect the intelligent driving effect and create safety hazards. Conversely, when the impact force is large, conventional reset mechanisms are prone to failure due to limitations in materials and space.

[0050] In view of this, the locking part 4 in this application is used to deal with the situation where the camera support arm 2 is subjected to a small impact force. In this case, the rotational stroke of the camera support arm 2 is small, and the locking part 4 can lock the camera support arm 2 and the support 1. However, when the camera support arm 2 is subjected to a large impact force, the rotational stroke of the camera support arm 2 around the bushing 3 from the initial position exceeds a preset threshold. At this time, the locking function of the locking part 4 fails due to the excessive rotational stroke. The monitoring unit detects that the rotational stroke of the camera support arm 2 around the bushing 3 from the initial position exceeds the preset threshold, and issues a command to the reset part 5 to activate the reset part 5 to perform a reset action on the camera support arm 2.

[0051] Optionally, the locking part 4 is a compression spring 41, and the compression force of the compression spring 41 is used as the locking force of the locking part 4. When the camera support arm 2 rotates, it will drive the bushing 3 to compress the compression spring 41, and at the same time, the compression spring 41 will also apply a reverse elastic reaction force to the bushing 3.

[0052] In some specific embodiments, such as Figure 4 and Figure 6 As shown, the bushing 3 has a first flange 31 at one end near the support 1, and a second flange 32 at the other end away from the support 1. The second flange 32 is attached to the side of the camera support arm 2 away from the support 1, and the compression spring 41 is provided between the first flange 31 and the support 1.

[0053] It is worth noting that when the camera support arm 2 rotates around the bushing 3 from its initial position, the camera support arm 2 drives the bushing 3 to move through the second flange 32, so that the first flange 31 presses the compression spring 41, and the compression spring 41 presses the camera support arm 2 and the support 1 together.

[0054] Preferably, the first contact surface between the camera support arm 2 and the support 1 is provided with a plurality of grooves 21, and the inner wall surface 211 of the grooves 21 is inclined. The support 1 is provided with a plurality of protrusions 11, and the protrusions 11 correspond one-to-one with the grooves 21.

[0055] In use, when the rotational stroke of the camera support arm 2 around the bushing 3 from its initial position is within a preset threshold, the first flange 31 presses against the compression spring 41, and the protrusion 11 moves along the inner wall surface 211 toward the opening of the groove 21. However, when the rotational stroke of the camera support arm 2 around the bushing 3 from its initial position exceeds the preset threshold, the protrusion 11 moves along the inner wall surface 211 through the opening of the groove 21 into an adjacent groove 21, and the compression spring 41 drives the protrusion 11 to move toward the bottom of the groove 21 where it is located.

[0056] It is worth noting that, such as Figure 4 and Figure 5 As shown, when the camera support arm 2 is subjected to a collision force... Figure 5 When rotating in the direction of arrow A, the groove 21 of the camera support arm 2 moves in the direction of arrow B (i.e., along the contact surface of the inner wall 211 and the protrusion 11). At this time, there is an inclined surface fit between the support 1 and the camera support arm 2, and the camera support arm 2 will move upward along the inclined surface, thereby driving the bushing 3 to move upward, causing further compression of the compression spring 41. The compression force generated by the compression spring 41 will prevent the camera support arm 2 from continuing to move upward, and thus prevent the rotation between the camera support arm 2 and the support 1. Therefore, under the action of a small external force, the support arm 2 and the support 1 will not rotate, which can ensure the stability of the camera angle and maintain the normal operation of the vehicle's intelligent driving function.

[0057] When the camera support arm 2 collides with the outside environment, the external force pushes the camera support arm 2 to rotate. This force can overcome the clamping force of the compression spring 41, ultimately causing the camera support arm 2 to move beyond the highest point of its engagement with the inclined surface of the support 1. At this point, each protrusion 11 passes through the highest point opening of its corresponding groove 21 and enters the adjacent groove 21. Since the clamping force applied by the compression spring 41 is perpendicular to the bottom surface of the groove 21, this clamping force will no longer drive the protrusion 11 back to its initial groove 21. Instead, it will drive the protrusion 11 to move towards the bottom of its current groove 21. This ensures that the camera support arm 2 is no longer obstructed by the compression spring 41 after the collision force, and also prevents the compression spring 41 from being permanently damaged. In this way, because the camera support arm 2 rotates and retracts with the support 1, the safety of the camera bracket is protected, preventing the bracket from breaking.

[0058] Furthermore, the reset part 5 includes: a torsion spring 51 and a limiting unit 52; wherein

[0059] A torsion spring 51, with its two ends connected to the support 1 and the camera support arm 2 respectively, is used to apply a rotational force to the camera support arm 2 as it rotates. A limiting unit 52 is disposed between the first flange 31 and the support 1, and is signal-connected to the monitoring unit.

[0060] When the monitoring unit detects that the rotational stroke of the camera support arm 2 around the bushing 3 from the initial position exceeds a preset threshold, the monitoring unit controls the limiting unit 52 to press the locking part 4 to separate the compression spring 41 from the bushing 3, so that the rotational force applied by the torsion spring 51 is sufficient to drive the camera support arm 2 back to the initial position.

[0061] As described above, when the camera support arm 2 rotates, the torsion spring 51 twists accordingly, generating a restoring force that allows the camera support arm 2 to return to its original state. However, as mentioned above, if the impact force is too large and the rotation of the camera support arm 2 exceeds a preset threshold, the clamping force generated by the compression spring 41 will no longer help the camera support arm 2 return to its original state; instead, it will prevent the camera support arm 2 from returning to its original state. Although the torsion spring 51 generates a restoring force through twisting, this restoring force is insufficient to overcome the clamping force of the compression spring 41 and allow the camera support arm 2 to return to its original state. At this time, the monitoring unit controls the limiting unit 52 to press the compression spring 41 (i.e., to counteract the clamping force of the compression spring 41). At this time, the compression spring 41 no longer presses the camera support arm 2 and the support 1 together, and the restoring force applied by the torsion spring 51 can drive the camera support arm 2 to return to its original state. When the monitoring unit detects that the camera support arm 2 has returned to its initial position, the limiting unit 52 stops pressing the compression spring 41, and the camera system returns to its initial function and position.

[0062] Preferably, such as Figure 4 As shown, the limiting unit 52 is an electromagnetic relay, which includes: a free end 521 and an electromagnetic end 522; wherein,

[0063] The free end 521 is attached to the support 1 and is located between the support 1 and the compression spring 41. The electromagnetic end 522 is attached to the first flange 31 and is connected to the monitoring unit. The electromagnetic end 522 is used to drive the free end 521 to move toward the electromagnetic end 522 to press the locking part 4.

[0064] When the camera support arm 2 and the support 1 rotate and retract, the camera angle changes, causing the intelligent driving system to malfunction and perform a self-check. When the problem is detected as a deflection of the rear-view camera, the system controls the electromagnetic terminal 522 to be energized, reducing the distance between the free end 521 and the electromagnetic terminal 522. At this time, the compression spring 41 is compressed under the action of the electromagnetic relay, and its elastic force is canceled by the magnetic force of the electromagnetic relay, so that the camera support arm 2 and the support 1 are in a relaxed state. At this time, the restoring force generated by the torsion spring 51 can restore the camera support arm 2 to its original state, realizing the automatic reset of the intelligent rear-view camera system. After the intelligent driving system is working normally, the system disconnects the energization of the electromagnetic relay, and the camera support arm 2 and the support 1 are fixed together again by the compression spring 41 to ensure the stability of the camera angle.

[0065] Preferably, such as Figure 2 As shown, the first contact surface between the camera support arm 2 and the support 1 is annular, with a through hole in the center for the bushing 3 to pass through, and multiple grooves 21 arranged circumferentially along the first contact surface. Optionally, the second contact surface on the support 1 is also annular, with a through hole in the center for the bushing 3 to pass through.

[0066] Preferably, the support 1 is used to connect with the vehicle body sheet metal 7. The support 1 is provided with a sealing gasket, which is located between the support 1 and the vehicle body sheet metal 7 to prevent water ingress and damage to the system. The support 1 and the camera support arm 2 are sleeved together by a bushing 3 and pressed together by a compression spring 41. The camera is mounted on the support arm by screws. The camera support arm 2 is provided with cable ties for fixing the wire harness.

[0067] Furthermore, the camera support arm 2 is provided with a cover 6, which is snapped into the camera support arm 2 to form an installation cavity for mounting the camera between the two.

[0068] On the other hand, this application provides an automobile, which includes: a vehicle body sheet metal 7 and any of the camera systems described above.

[0069] The camera system includes: a support 1, a camera support arm 2, and a flexible reset assembly; wherein...

[0070] A camera support arm 2 is rotatably connected to the support 1 via a bushing 3, and the camera support arm 2 can rotate around the bushing 3. An elastic reset assembly is disposed between the support 1 and the camera support arm 2; wherein...

[0071] When the camera support arm 2 rotates around the bushing 3 from its initial position, the elastic reset component applies a force to the camera support arm 2 in the opposite direction of its rotation until the camera support arm 2 returns to its initial position.

[0072] Furthermore, the elastic reset assembly includes a locking part 4 and a reset part 5, both of which are located between the support 1 and the camera support arm 2. The reset part 5 is signal-connected to the monitoring unit. The locking part 4 is a compression spring 41, and the compression force of the compression spring 41 serves as the locking force of the locking part 4. When the camera support arm 2 rotates, it will drive the bushing 3 to compress the compression spring 41, while the compression spring 41 simultaneously applies a reverse elastic reaction force to the bushing 3.

[0073] In some specific embodiments, such as Figure 4 and Figure 6 As shown, the bushing 3 has a first flange 31 at one end near the support 1, and a second flange 32 at the other end away from the support 1. The second flange 32 is attached to the side of the camera support arm 2 away from the support 1, and the compression spring 41 is provided between the first flange 31 and the support 1.

[0074] Preferably, the first contact surface between the camera support arm 2 and the support 1 is provided with a plurality of grooves 21, and the inner wall surface 211 of the grooves 21 is inclined. The support 1 is provided with a plurality of protrusions 11, and the protrusions 11 correspond one-to-one with the grooves 21.

[0075] Furthermore, the reset part 5 includes: a torsion spring 51 and a limiting unit 52; wherein

[0076] A torsion spring 51, with its two ends connected to the support 1 and the camera support arm 2 respectively, is used to apply a rotational force to the camera support arm 2 as it rotates. A limiting unit 52 is disposed between the first flange 31 and the support 1, and is signal-connected to the monitoring unit.

[0077] Preferably, such as Figure 4 As shown, the limiting unit 52 is an electromagnetic relay, which includes: a free end 521 and an electromagnetic end 522; wherein,

[0078] The free end 521 is attached to the support 1 and is located between the support 1 and the compression spring 41. The electromagnetic end 522 is attached to the first flange 31 and is connected to the monitoring unit. The electromagnetic end 522 is used to drive the free end 521 to move toward the electromagnetic end 522 to press the locking part 4.

[0079] In summary, this application incorporates an elastic reset component between the bracket and the camera support arm to automatically address the rotation of the camera support arm due to an external collision. This ensures that the rearview camera used in intelligent driving can rotate after a collision to protect the system from damage, and prevents the intelligent driving system from malfunctioning due to a shift in the camera angle caused by bracket rotation, thus ensuring driving safety. Furthermore, to address the issue of excessive impact force on the camera support arm causing the conventional reset component to fail, this application employs a monitoring unit to monitor the position of the camera support arm in real time. If excessive rotation occurs that cannot be reversed, the monitoring unit electronically controls the camera support arm to return to its initial position.
