[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.

[0016] like Figure 1 As shown, the electric lifting device for car emblems includes an emblem unit 1 and a sliding mechanism 2 for connecting the emblem unit 1 and driving it to move up and down. The sliding mechanism 2 is connected to a guide rail 3, and its bottom is connected to a driver assembly 5. The driver assembly 5 drives the sliding mechanism 2 to move up and down on the guide rail 3, so that the emblem unit 1 can be raised and lowered. At the same time, the structure of the sliding mechanism 2 can also enable the emblem unit 1 to be quickly lowered when anti-theft or pedestrian protection functions are activated.

[0017] The sliding mechanism 2 includes a base 9 and a car logo base unit. The base 9 and the car logo base unit are rigidly connected as one unit and are connected to the guide rail 3. The car logo base unit includes a car logo base 19, a spring seat 7, a trigger spring 11, a guide tube 12, an unlocking link 13, and a locking tongue 14. The car logo base 19 is fixed to the upper end of the spring seat 7. The trigger spring 11 is located at the lower end of the spring seat 7 and is sleeved on the guide tube 12. A guide sleeve 18 is also sleeved on the guide tube 12 and located at the lower end of the trigger spring 11. The upper end of the guide tube 12 abuts against the spring seat 7, and the lower end is connected to the unlocking link 13. The other side of the unlocking link 13 is connected to the locking tongue 14. A return torsion spring 8 is provided on the pin connecting the unlocking link 13 to the locking tongue 14. The sliding mechanism 2 also includes a nut slider 15, which is also connected to the guide rail 3. The nut slider 15 is provided with a wedge-shaped opening 16 that engages with the locking tongue 14. The sliding mechanism 2 is an important component of the car logo unlocking mechanism. The nut slider 15 contains a locking tongue engagement mechanism. When the car logo is raised, the locking tongue 14 engages in the wedge-shaped opening of the nut slider 15. The driver assembly 5 drives the nut slider 15 to move up and down. The nut slider 15 transmits the lifting force to the car logo base unit through the engaged locking tongue 14. The car logo base unit, composed of the car logo base 19, spring seat 7, trigger spring 11, guide tube 12, unlocking link 13 and locking tongue 14, drives the car logo unit 1 to move up and down, thereby driving the car logo 10 to move up and down.

[0018] The upper surface of the logo base 19 is provided with a ball joint 20 in the circumferential direction. When the logo 10 is subjected to a downward impact pressure or a push-pull force in any circumferential direction, it is transmitted to the logo base 19. The vertical downward pressure can be directly transmitted to the trigger spring 11 through the spring seat 7. The circumferential push-pull force is transmitted to the logo base 19 with the ball joint 20 under the restriction of the support cover 17, and then transmitted to the logo base 19, and then to the trigger spring 11. After the trigger spring 11 is compressed, the unlocking link 13 moves downward along the guide sleeve 18, presses the locking tongue 14 to rotate and unlock, and then disengages from the nut slider 15. In this way, the logo base unit composed of the logo base 19, spring seat 7, trigger spring 11, guide tube 12, unlocking link 13 and locking tongue 14 disengages from the nut slider 15 and quickly retracts under its own weight and the action of the tension spring 7.

[0019] The logo unit 1 includes a logo 10 and a support cover 17. The logo 17 passes through the support cover 17 and its bottom end is fixed to the upper surface of the logo base 19.

[0020] The drive assembly 5 includes a protective tube 21, an end cover 22, a motor assembly 23, a gearbox assembly 24, a brake assembly 25, and a lead screw 26. The end cover 22 is rigidly connected to the protective tube 21. The motor assembly 23, gearbox assembly 24, and brake assembly 25 are assembled and fixedly connected in sequence inside the protective tube 21. The lead screw 26 is connected to the front end of the brake assembly 25. The motor assembly 23 converts the received controller signal into mechanical motion, adjusts the speed through the gearbox assembly 24, and transmits the rotational motion to the lead screw 26 through the brake assembly 25. The lead screw 26 is connected to the nut slider 15, and the lead screw 26 and the nut slider 15 convert the rotational motion into linear motion. When the actuator assembly becomes an electric strut, its durability can reach over 100,000 cycles, improving the service life of the electric emblem lifting device. Simultaneously, by adjusting the braking torque, the electric strut can meet the application requirements of different vehicle emblem lifting device actuators, reducing the development and unit cost of the electric emblem lifting device actuator. As a single linear unit structure, the electric strut is arranged within the hood compartment, reducing the space occupied in the Y direction and improving the OEM's compartment space utilization. When the anti-theft and pedestrian safety protection functions are triggered, the mature mechanical locking and unlocking mechanism allows the emblem to retract quickly, achieving both emblem anti-theft and pedestrian protection functions.

[0021] The drive assembly 5 includes a motor 37, with a worm shaft 39 on the motor 37 meshing with a worm gear 42. The worm gear 42 is connected to a lead screw 26, which also has a bearing 38 and a brake 41. The bearing 38 is connected to the upper end of the worm gear 42, and the brake 41 is connected to the lower end of the worm gear 42. The worm gear 42, bearing 38, and brake 41 are fixedly installed inside a protective housing 40, and the motor 37 is laterally positioned on one side of the protective housing 40. When the drive assembly uses a compact worm gear drive system in conjunction with a lead screw to transmit motion, it achieves linear lifting and lowering of the car emblem within a confined space. Simultaneously, the adjustable drive system brake provides the system with good damping and hovering capabilities. When the safety protection is triggered, a reliable mechanical locking and unlocking mechanism is used to rigidly break the car logo and drive motor, and to quickly retract the car logo, thus achieving the purpose of protecting pedestrians and the car logo. Compared with the current traditional drive mechanism that uses linkage or fixed track motion control, the use of screw motion combined with a flexible multi-link motion mechanism effectively shortens the horizontal X and Y dimensions, which is beneficial to the layout of the vehicle's front compartment.

[0022] One side of the sliding mechanism 2 is connected to the car emblem decoration mechanism 6. The car emblem decoration mechanism 6 includes a connecting rod assembly 27 and a car emblem decoration cover 28. The car emblem decoration cover 28 is connected to the upper end of the connecting rod assembly 27. The connecting rod assembly 27 includes connecting rod 1 35, connecting rod 29, connecting rod 30, connecting rod 4 31 and V-shaped connecting rod 32. One end of connecting rod 1 35 is connected to the car body shell through connecting rod pin 1 34, and the other end of connecting rod 1 35 is connected to the middle of connecting rod 30. One end of rod 29 is connected by a hinge, and the other end of rod 29 is connected to one end of V-shaped connecting rod 32 by a hinge. The upper end of connecting rod 30 is connected to the car logo decorative cover 28, and the lower end is connected to one end of connecting rod 4 31 by a hinge. The other end of connecting rod 4 31 is connected to the body shell by connecting rod pin 2 36. The middle bend of V-shaped connecting rod 32 is connected to the body shell by connecting rod pin 3 33, and the other end of V-shaped connecting rod 32 is connected to the base 9 by a hinge. The drive assembly 5 moves up and down on the guide rail 3 by driving the sliding mechanism 2. The car logo unit 1 is fixed on the sliding mechanism 2 to realize the extension and retraction of the car logo. The car logo decoration mechanism 6 includes a connecting rod assembly 27 and a car logo decorative cover 28. During the downward movement of the sliding mechanism 2, the connecting rod assembly 27 is used to raise the car logo decorative cover 28, which covers the sheet metal display hole after the support cover 17 is retracted.

[0023] A tension spring 4 is connected to the sliding mechanism 2. One end of the tension spring 4 is connected to the base 9, and the other end is connected to the vehicle body shell. When the car emblem 10 rises with the sliding mechanism 2, the tension spring 4 is stretched and deformed, storing elastic potential energy. This provides a downward force to activate the car emblem's anti-theft function or pedestrian protection, allowing the car emblem to quickly retract. Example

[0024] When only the logo unit 1 needs to be driven to move up and down normally, the driver assembly drives the sliding mechanism 2 to move up and down on the guide rail 3, so that the logo unit 1 can achieve the purpose of raising and lowering.

[0025] When the anti-theft or pedestrian protection functions are activated, if the emblem 10 is subjected to external tension, pressure, or circumferential force from a collision, the external force is transmitted from the emblem 10 through the support cover 17 to the emblem base 19. The downward pressure is transmitted through the spring seat 7 to the trigger spring 11. After being compressed, the trigger spring 11 deforms and pushes the unlocking linkage 13 and the guide tube 12 downward, pushing the locking tongue 14 to rotate around the locking tongue pin. The locking tongue 14 disengages from the wedge-shaped opening of the screw nut 15. Under the tension of the tension spring 4, the sliding mechanism 2 drives the emblem 10 to retract quickly, realizing the anti-theft and pedestrian protection functions of the emblem. When the emblem lifting function is activated again, the controller control logic needs to perform a zero-position confirmation. The driver assembly 5 drives the nut slider 15 to move downward. When the position of the wedge-shaped opening 16 of the nut slider 15 moves to the engagement position of the locking tongue 14, the reset torsion spring 8 provides a reversing torque to the locking tongue 14, so that the locking tongue 14 engages with the wedge-shaped opening 16 of the nut slider 15, preparing for the emblem to be lifted again. The mechanically designed engagement and unlocking structure, compared to electronic sensors, improves reliability, eliminates the need for sensors, and further reduces application costs.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
