Description

Technical Field

[0001] The present invention relates to the field of optical systems, and in particular to a vehicle-mounted optical lens intelligent display device. Background Art

[0002] The in-vehicle optical lens intelligent display device records images, sounds, and other related information while a vehicle is in motion, or provides a reverse image display. Once installed, it can record video and sound throughout the entire driving process, providing evidence in the event of a traffic accident. It features high concealment, easy installation, removable and replaceable, low cost, and ease of use.

[0003] It is usually installed above the front windshield of the vehicle to provide a good shooting angle. However, due to the different individual conditions of different drivers, the angle needs to be adjusted, which requires setting the degree of freedom for users to adjust. However, if the degree of freedom is released, the device may be affected by the inertia of the vehicle when a collision occurs, and there is a risk that the device will be peeled off from the front windshield after the impact, which will not only damage the device, but also easily cause impact to the driver and passengers, causing secondary injuries.

[0004] Therefore, a new type of vehicle-mounted optical lens intelligent display device is needed to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a vehicle-mounted optical lens intelligent display device.

[0006] To achieve the above object, the present invention provides the following technical solutions: A vehicle-mounted optical lens intelligent display device includes a display body. The center of the back of the display body is connected to a rotating shaft via a universal joint ball. The rotating shaft is hinged on an adhesive base. The rotating direction of the rotating shaft is set at an oblique angle to the direction of the vehicle head. A camera module is set on one side of the back of the display body.

[0007] As a further solution of the present invention, the oblique angle of the rotating shaft is set in the direction of the main driving direction.

[0008] As a further solution of the present invention: secondary damping rings are provided on the rotating sleeves at both ends of the rotating shaft, which are hinged to the adhesive base through the secondary damping rings. A speed limit lock structure is provided in the secondary damping rings. When the rotating shaft rotates at an overspeed, the circumferential angle connection between the secondary damping ring and the rotating shaft is locked. The rotational damping between the secondary damping ring and the adhesive base is greater than the rotational damping between the rotating shaft and the secondary damping ring.

[0009] As a further solution of the present invention: the secondary damping ring includes a guide plate, a reset rod and a locking bead. The guide plate is a circular structure sleeved on both ends of the rotating shaft. An arc-shaped guide groove is cut on the guide plate at a position that fits the inner wall. The center of the arc-shaped guide groove is eccentrically arranged with the center of the guide plate, so that the arc-shaped guide groove is spirally distributed toward the center of the guide plate. A locking bead is rolled and embedded in the arc-shaped guide groove, and the locking bead protrudes from the arc-shaped guide groove. A reset rod is slidably arranged at one end of the arc-shaped guide groove close to the center of the guide plate, and a reset spring is sleeved on the outer side of the reset rod. The reset spring acts on the reset rod to make the reset rod maintain the tendency of pushing the locking bead to move along the arc-shaped guide groove away from the center of the guide plate.

[0010] As a further solution of the present invention: the locking beads and the reset rods are arranged in groups symmetrically along the center of the guide disc.

[0011] As a further solution of the present invention, two groups of locking beads and reset rods are axially symmetrically arranged, and the spiral directions of the arc-shaped guide grooves in which the two groups of locking beads and reset rods are embedded are opposite.

[0012] As a further solution of the present invention: one end of the reset rod close to the locking bead is connected to a tray structure.

[0013] As a further solution of the present invention: the secondary damping ring also includes a force unloading damping end cover, which is connected to the outer end of the guide plate and is rotatably connected to the adhesive base. It has a protruding petal structure, and an end plug is clamped on the adhesive base. The end plug has a contact structure outside that engages with the petal structure of the force unloading damping end cover.

[0014] As a further solution of the present invention: the petal-shaped structure of the force-unloading damping end cover is a hollow structure with upper and lower ends passing through. Beneficial effects

[0015] 1. The back center of the display body of the present invention is connected to a rotating shaft via a universal joint ball. The rotating shaft is hinged on the adhesive base. The rotating direction of the rotating shaft is set at an oblique angle to the direction of the vehicle head. A camera module is set on one side of the back of the display body. The oblique angle between the rotating direction of the rotating shaft and the direction of the vehicle head can prevent the device from being directly rotated and thrown out along the rotating shaft under the action of inertia in the event of a collision. The oblique angle is used to buffer the inertial movement of the device, thereby reducing the possibility of damage to the device connection structure or peeling at the adhesive position, thereby avoiding damage to the device or injury to the driver and passengers.

[0016] 2. The rotating sleeves at both ends of the rotating shaft of the present invention are provided with secondary damping rings, which are hinged to the adhesive base through the secondary damping rings. A speed limit lock structure is provided in the secondary damping rings. When the rotating shaft rotates at an overspeed, the circumferential angle connection between the secondary damping ring and the rotating shaft is locked. The rotational damping between the secondary damping ring and the adhesive base is greater than the rotational damping between the rotating shaft and the secondary damping ring. By utilizing the speed limit lock and the secondary damping ring with a stronger damping force, when the display body of the device drives the rotating shaft to rotate at a high speed under the action of motion inertia, the speed limit lock will be driven to lock the degree of freedom between the secondary damping ring and the rotating shaft, and the stronger damping force between the secondary damping ring and the adhesive base is utilized to play a fixing and buffering role. When the low-speed rotation of the device is adjusted normally, the lower rotation damping force between the rotating shaft and the secondary damping ring is used for adjustment, so as to facilitate the adjustment.

[0017] 3. The secondary damping ring of the present invention also includes a force-unloading damping end cover, which is connected to the outer end of the guide plate and is rotatably connected to the adhesive base. It has a protruding petal structure, and an end plug is clamped on the adhesive base. A contact structure is provided on the outside of the end plug, which engages with the petal structure of the force-unloading damping end cover. The energy of the equipment inertia is absorbed through the periodic friction and disconnection between the petal structure and the end plug contact, rather than forcibly restricting the movement of the equipment through large damping, thereby avoiding damage to the equipment connectors and playing a protective role.

[0027] The following is a diagram of the present invention Figures 1-8 , clearly and completely describe the specific technical solutions of the present invention; See also Figures 1-8 , Figure 1 Schematic diagram of the overall structure of an embodiment of the present invention; Figure 2 It is a schematic diagram of the back structure of the present invention; Figure 3 Schematic diagram of the connection structure of the present invention; Figure 4 This is an exploded schematic diagram of the connection structure of the present invention; Figure 5 This is a schematic diagram of the explosion of the secondary damping ring structure of the present invention; Figure 6 It is a schematic diagram of the guide plate structure of the present invention; Figure 7 This is a cross-sectional view of the force-unloading damping end cover structure of the present invention; Figure 8 It is a schematic diagram of the end plug structure of the present invention.

[0028] This embodiment provides a vehicle-mounted optical lens intelligent display device, comprising a display body 1. A rotating shaft 4 is connected to the center of the back of the display body 1 via a universal joint ball 3. The rotating shaft 4 is hinged to an adhesive base 6. The rotating direction of the rotating shaft 4 is set at an oblique angle to the direction of the vehicle's front. A camera module 2 is provided on one side of the back of the display body 1. By setting the angle between the rotation direction of the rotating shaft 4 and the direction of the vehicle head, the device can be prevented from being directly rotated and thrown out along the rotating shaft 4 under the action of inertia in the event of a collision. The oblique angle is used to buffer the inertial movement of the device, thereby reducing the possibility of breakage of the device connection structure or peeling of the adhesive position, thereby avoiding damage to the device or injury to the driver and passengers.

[0029] The oblique angle of the rotating shaft 4 is set in the direction of the main driving direction, so that the driver can adjust the angle and position of the display body 1 more easily.

[0030] Among them, the rotating sleeves at both ends of the rotating shaft 4 are provided with secondary damping rings 5, which are hinged to the adhesive base 6 through the secondary damping rings 5. A speed limit lock structure is provided in the secondary damping ring 5. When the rotating shaft 4 rotates at an overspeed, the circumferential angle connection between the secondary damping ring 5 and the rotating shaft 4 is locked. The rotational damping between the secondary damping ring 5 and the adhesive base 6 is greater than the rotational damping between the rotating shaft 4 and the secondary damping ring 5; By utilizing the setting of the speed limit lock and the secondary damping ring 5 with stronger damping force, when the device display body 1 drives the rotating shaft 4 to rotate at high speed under the action of motion inertia, the speed limit lock will be driven to lock the freedom between the secondary damping ring 5 and the rotating shaft 4, and the stronger damping force between the secondary damping ring 5 and the adhesive base 6 will be used to fix and buffer the device. When adjusting the low-speed rotation of the device at ordinary times, the lower rotation damping force between the rotating shaft 4 and the secondary damping ring 5 is used for adjustment, so as to facilitate the adjustment.

[0031] Specifically, the secondary damping ring 5 includes a guide plate 51, a reset rod 52 and a locking bead 53. The guide plate 51 is a circular ring structure sleeved on both ends of the rotating shaft 4. An arc-shaped guide groove is cut on the guide plate 51 at a position where it fits the inner wall. The center of the arc-shaped guide groove is eccentric to the center of the guide plate 51, so that the arc-shaped guide groove is spirally distributed toward the center of the guide plate 51. A locking bead 53 is rolled and embedded in the arc-shaped guide groove, and the locking bead 53 protrudes from the arc-shaped guide groove. A reset rod 52 is slidably provided at one end of the arc-shaped guide groove close to the center of the guide plate 51. A reset spring 54 is sleeved on the outer side of the reset rod 52. The reset spring 54 acts on the reset rod 52 to keep the reset rod 52 pushing the locking bead 53 to move along the arc-shaped guide groove away from the center of the guide plate 51. By setting the damping ball that moves toward the center of the spiral guide disk 51, when the rotation speed of the rotating shaft 4 is too fast, the force of the reset rod 52 is less than the driving force of the rotating shaft 4 on the damping ball, and the damping ball will move toward the center side of the guide disk 51 under the drive of the rotating shaft 4, thereby squeezing the rotating shaft 4 structure and realizing the locking of the freedom between the rotating shaft 4 and the guide disk 51.

[0032] Furthermore, the locking bead 53 and the reset rod 52 are arranged in a group symmetrically along the center of the guide plate 51, thereby providing more uniform force for the rotation of the shaft 4, avoiding uneven force caused by the rotation of the shaft 4 itself through the lever of the display body 1, and improving the smoothness of the rotation of the shaft 4.

[0033] Furthermore, two groups of locking beads 53 and the reset rod 52 are axially symmetrically arranged, and the spiral directions of the arc guide grooves in which the two groups of locking beads 53 and the reset rod 52 are embedded are set in opposite directions, so as to adapt to the changes in the two movement directions of the display body 1 that may occur due to different angles when a collision occurs. No matter which flipping direction, the movement of the locking beads 53 can be triggered to achieve locking of the freedom between the rotating shaft 4 and the secondary damping ring 5.

[0034] Furthermore, one end of the reset rod 52 close to the locking bead 53 is connected to a tray structure, thereby better guiding the movement of the locking bead 53.

[0035] Furthermore, the secondary damping ring 5 also includes a force unloading damping end cap 55, which is connected to the outer end of the guide plate 51 and is rotatably connected to the adhesive base 6. The end cap 55 has a protruding petal-shaped structure. The adhesive base 6 is provided with an end plug 7. The end plug 7 has a contact structure on the outside that engages with the petal-shaped structure of the force unloading damping end cap 55. By periodically contacting and disconnecting the petal-shaped structure and the end plug 7 contacts, the inertia of the equipment is absorbed, rather than forcibly restricting the movement of the equipment through large damping, thus avoiding damage to the equipment connectors and playing a protective role.

[0036] Furthermore, the petal-shaped structure of the force-unloading damping end cover 55 is a hollow structure with both ends passing through, thereby improving the deformation capacity of the structure and achieving energy absorption through the deformation of the petal-shaped structure.

[0037] When the technical solution described in this embodiment is implemented, when the driver adjusts the position and angle of the display body 1, due to the slow rotation speed of the rotating shaft 4 during the adjustment process, the movement of the locking bead 53 is reset by the reset rod 52 and the reset spring 54. The adjustment of the device is adjusted by the lower rotation damping force between the rotating shaft 4 and the secondary damping ring 5, which facilitates the adjustment. When a collision occurs, due to inertia, the display body 1 drives the rotating shaft 4 to rotate at high speed. The force of the rotating shaft 4 on the locking bead 53 overcomes the action of the reset rod 52 and the reset spring 54, thereby driving the damping bead to move toward the center side of the guide plate 51, thereby squeezing the rotating shaft 4 structure, and realizing the locking of the freedom between the rotating shaft 4 and the guide plate 51. The stronger damping force between the secondary damping ring 5 and the adhesive base 6 is used to play a fixing and buffering role, thereby reducing the possibility of damage to the equipment connection structure or peeling off at the adhesive position, thereby avoiding damage to the equipment or injury to the driver and passengers.
