Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a vehicle logo lifting drive mechanism, a lifting vehicle logo, and a vehicle. Background Technology

[0002] Currently, due to requirements such as anti-theft measures for car emblems, some car models that use upright emblems also allow the emblem to be lowered below the hood, thus becoming retractable emblems. However, existing emblem retraction drive structures generally use spring-driven force to lower the emblem. While this method can achieve the lowering of the emblem, it is also prone to deformation or damage to the emblem components due to excessive driving force, which is detrimental to improving the overall quality of retractable emblems. Utility Model Content

[0003] In view of this, the present invention aims to propose a car logo lifting drive mechanism to improve the quality of use of lifting car logos.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A car logo lifting drive mechanism is used to drive a car logo assembly to lift and lower, and includes a rotary drive unit disposed on a mounting base, and a first car logo link and a second car logo link hinged between the car logo assembly and the mounting base;

[0006] The car logo component, the mounting base, the first car logo link and the second car logo link form a four-bar linkage, and a transmission component is provided between the second car logo link and the rotary drive unit;

[0007] Driven by the rotary drive unit, the transmission assembly can drive the second logo link to swing, and the swinging second logo link can drive the logo assembly to move to a raised state or a lowered state.

[0009] The first and second logo links are hinged to the mounting base at one end, and the logo assembly, the mounting base, the first logo link and the second logo link form the four-bar linkage.

[0010] Furthermore, the power output end of the rotary drive unit is provided with a drive linkage;

[0011] One end of the drive linkage is connected to the power output end, and the transmission assembly is connected to the other end of the drive linkage.

[0012] Furthermore, the transmission assembly includes a rocker arm with one end hinged to the drive linkage, and a first transmission rod with one end hinged to the mounting base.

[0013] The other end of the rocker arm is provided with a first sliding groove, the other end of the first transmission rod is provided with a first sliding shaft, and a protrusion protruding to one side is provided in the middle of the first transmission rod, and a second sliding shaft is provided on the protrusion.

Compared with the existing technology that uses spring output driving force to drive the car logo to move, it can avoid the deformation or damage of parts caused by excessive driving force, thereby improving the quality of use of the lifting car logo.

[0022] Furthermore, by setting up a connecting rod, a rotating block, and a pressure rod, as well as a limiting structure and a clamping spring on the pressure rod, the first sliding shaft in the second sliding groove and the second sliding shaft in the first sliding groove can always be kept under force under the preload of the clamping spring, thus avoiding the situation where power cannot be transmitted.

[0055] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] Example 1

[0057] This embodiment relates to a car logo lifting drive mechanism (hereinafter referred to as drive mechanism 4), which is suitable for lifting car logos installed at the front of a vehicle. The drive mechanism 4 can lift the car logo component 3 under the drive of the rotary drive unit 2, which helps to improve the quality of use of the lifting car logo.

[0058] In terms of overall structure, combined Figures 1 to 4 As shown, the drive mechanism 4 in this embodiment includes a rotary drive unit 2 disposed on the mounting base 1, and a first car logo link 401 and a second car logo link 402 hinged between the car logo assembly 3 and the mounting base 1.

[0059] The logo assembly 3, the mounting base 1, the first logo link 401, and the second logo link 402 form a four-bar linkage, and a transmission assembly 40 is provided between the second logo link 402 and the rotary drive unit 2. Driven by the rotary drive unit 2, the transmission assembly 40 can drive the second logo link 402 to swing, and the swinging second logo link 402 can drive the logo assembly 3 to move to a raised or lowered state.

[0060] At this time, driven by the rotary drive unit 2, and driven by the transmission component 40 and the second logo link 402, the logo component 3 can be raised and lowered in this embodiment. Compared with the form of using spring output driving force to move the logo in the prior art, this embodiment can also avoid deformation or damage of parts due to excessive driving force, so as to improve the quality of use of the lifting logo.

[0061] Based on the above overall introduction, specifically, the mounting base 1 serves as the foundation for the entire car logo product. For example, it can adopt a plate-like structure. In addition to a plate-like structure, the mounting base 1 can also adopt other structural forms that meet the corresponding design requirements, without any restrictions.

[0062] In practice, a mounting structure connected to the vehicle body can be provided on the mounting base 1 to fix the mounting base 1 to the vehicle body, thereby realizing the placement of the vehicle logo product in the vehicle. These mounting structures can adopt conventional forms such as mounting holes or mounting studs. In order to facilitate placement in the vehicle, the above-mentioned mounting structures can also be equipped with tolerance adjusters, for example, to adjust the position of the mounting base 1 during installation, thereby improving assembly efficiency.

[0063] In addition to the mounting structure connected to the vehicle body, this embodiment also provides a structure on the mounting base 1 for mounting components such as the rotary drive unit 2. In specific implementation, these structures can still use conventional mounting holes or mounting studs, which will not be described in detail here.

[0064] In this embodiment, as a preferred implementation, the rotary drive unit 2 can generally be a motor, and is further combined with... Figures 5 to 7 As shown, a drive link 201 is also provided at the power output end of the rotary drive unit 2. One end of the drive link 201 can be connected to the power output end of the rotary drive unit 2 via a motor connecting shaft 201a, while a first connecting part 201b connected to the transmission assembly 40 is provided at the other end of the drive link 201.

[0065] Furthermore, as a preferred embodiment, this embodiment also provides a mounting base 101 on the mounting base 1. The ends of the first car logo link 401 and the second car logo link 402 that are connected to the mounting base 1 are hinged to the mounting base 101. Correspondingly, the four-bar linkage is also formed by the car logo component 3, the mounting base 101, and the first car logo link 401 and the second car logo link 402.

[0066] It is understandable that by setting up the first logo link 401 and the second logo link 402, and forming a four-bar linkage between the logo component 3, the mounting base 101, and the first and second logo links 401, the logo component 3 can be rotated relative to the mounting base 101 along a set path using the two logo links, thereby achieving the lifting and lowering of the logo component 3. The set path is determined by structural parameters such as the length of the two logo links, and these parameters can be selected according to specific design requirements.

[0067] In practice, the aforementioned mounting base 101 can generally be fixed to the mounting base 1 by conventional methods such as screwing, riveting or welding.

[0068] And such Figures 8 to 10 As shown, the mounting base 101 is also provided with a first connecting rod hinge hole 101a and a second connecting rod hinge hole 101b. The first connecting rod hinge hole 101a is used to hinge one end of the first car logo connecting rod 401, and the second connecting rod hinge hole 101b is used to hinge one end of the second car logo connecting rod 402. The other ends of the first car logo connecting rod 401 and the second car logo connecting rod 402 can be respectively hinged in the corresponding hinge holes on the car logo assembly 3.

[0069] In this embodiment, as a feasible implementation, the first logo link 401 may structurally include, for example, two oppositely arranged first arms 401a, and a connecting cross arm 401b connecting the two first arms 401a. Furthermore, in a specific implementation, the two first arms 401a can be hinged to the mounting base 101 and the logo bracket 301 respectively via first hinge shafts 401c at both ends, thereby achieving the hinged arrangement of the first logo link 401 between the mounting base 101 and the logo assembly 3.

[0070] Similar to the structure of the first logo bracket 401, the second logo link 402 in this embodiment may also include two opposing second arms 402a. The two second arms 402a can be connected together by a connecting rod 405. In specific implementation, the two second arms 402a can also be hinged to the mounting base 101 and the logo bracket 301 respectively through the second hinge shafts 402b at both ends, so as to achieve the hinged setting of the second logo link 402 between the mounting base 101 and the logo component 3.

[0071] It is worth noting that the connecting crossarm 401b located between the two first arms 401a can be configured as a single unit or multiple units arranged at intervals, as needed. In addition to the connecting rod 405, other connecting structures similar to the connecting crossarm 401b can be further provided between the two second arms 401a in the second logo connecting rod 402, without affecting the operation of other surrounding components, and arranged at intervals from the connecting rod 405. Of course, from the perspective of achieving the connection between the two arms, the connecting rod 405 and the connecting crossarm 401b serve the same function.

[0072] In this embodiment, as a feasible implementation, the transmission component 40 may include, for example, a rocker arm 403 with one end hinged to the first connecting part 201b, and a first transmission rod 404 with one end hinged to the mounting base 101.

[0073] At this point, continue combining Figure 11 and Figure 12 As shown, a first groove 403b is provided at the other end of the rocker arm 403, and a first sliding shaft 409 is provided at the other end of the first transmission rod 404. Simultaneously, a protrusion 404b protruding to one side is also provided in the middle of the first transmission rod 404, and a second sliding shaft 4010 is provided on this protrusion 404b. The first sliding shaft 409 is slidably disposed within a second groove 402c on the second logo connecting rod 402, while the second sliding shaft 4010 is slidably disposed within the first groove 403b located at one end of the rocker arm 403.

[0074] In specific implementation, it should be noted that it still needs to be combined with Figure 10 and Figure 11 As shown, both the first groove 403b and the second groove 402c are elongated grooves.

[0075] The first transmission rod 404 can be hinged to the mounting base 101 via a hinge rod 402a at one end and a transmission rod hinge hole 101c on the mounting base 101. Meanwhile, the rocker arm 403 and the first connecting portion 201b on the drive link 201 can also be connected via a conventional hinge using a rocker arm hinge hole 403a at one end of the rocker arm 403.

[0076] In addition, in this embodiment, it is still as follows Figure 11 As shown, the portion of the rocker arm 403 located between its two ends can also be configured as a curved shape. In this way, by making the main body of the rocker arm 403 curved, it can provide clearance space for other peripheral components, which can facilitate the arrangement of peripheral components while realizing the transmission function of the rocker arm 403 itself.

[0077] In this embodiment, as a preferred implementation, the following is continued... Figure 13 As shown, based on the connecting rod 405 provided on the second logo link 402, a rotating block 102 is also rotatably provided on the mounting base 101, and a pressure rod 406 is provided through the rotating block 102.

[0078] See also Figure 6 As shown, one end of the pressure rod 406 is movably connected to the connecting rod 405, and a limiting structure 408 and a compression spring 407 located between the limiting structure 408 and the rotating block 102 are provided on the pressure rod 406. The position of the limiting structure 408 on the pressure rod 406 is adjustable so that the compression amount of the compression spring 407 can be adjusted.

[0079] At this time, by setting the aforementioned rotating block 102 and pressure rod 406, as well as the limiting structure 408 and compression spring 407 provided on the pressure rod 406, this embodiment can ensure that the first sliding shaft 409 is always under force in the second sliding groove 402c and the second sliding shaft 4010 is always under force in the first sliding groove 403b under the pre-tightening force of the compression spring 407. This can avoid the situation where the transmission component 40 and the second logo connecting rod 402 cannot transmit power, and can ensure the reliability of the lifting control of the logo component 3 under the drive of the rotating drive unit 2.

[0080] In practice, the rotating block 102 can be mounted on the mounting base 101 using a conventional rotating connection.

[0081] For the movable connection between the pressure rod 406 and the connecting rod 405, for example, a connecting seat 406a can be provided at one end of the pressure rod 406. The connecting seat 406a has an arc-shaped groove. The connecting seat 406a is fastened to the connecting rod 405 by using the groove, which can realize the movable connection between the pressure rod 406 and the connecting rod 405. And based on the clamping force provided by the compression spring 407, it can also be ensured that the connecting seat 406a and the connecting rod 405 will not become loose.

[0082] In a preferred embodiment of the aforementioned limiting structure 408, the end of the pressure rod 406 near the connecting seat 406a may be provided with an external thread, and the limiting structure 408 may be screwed onto the pressure rod 406 in a structure similar to a nut. In this case, the limiting structure 408 is screwed onto the pressure rod 406, which not only simplifies the structure and makes it easy to design and implement, but also facilitates the adjustment of the position of the limiting structure 408, thereby adjusting the compression of the compression spring 407.

[0083] In this embodiment, as a preferred implementation, the following is continued... Figure 2 As shown, a limiting block 103 can also be provided on the mounting base 1. This limiting block 103 is used to limit the second logo link 402 when the drive mechanism 4 drives the logo assembly 3 to move and descend. In specific implementation, the limiting block 103 can adopt a conventional structure such as a limiting pin fixed on the mounting base 1, and a buffer structure such as rubber can also be provided on the limiting block 103 to avoid collision noise.

[0084] Based on the above settings, when the drive mechanism 4 of this embodiment is used, taking the car logo component 3 descending as an example, the controller in the vehicle used for car logo lifting control, such as the vehicle controller, issues a control command to make the rotary drive unit 2 move, which drives the drive linkage 201 to rotate. The drive linkage 201 drives the rocker arm 403 to move through the first connecting part 201b on it. The first sliding groove 403b on the rocker arm 403 drives the first transmission rod 404 to rotate around the mounting base 101 through the second sliding shaft 4010, thereby causing the first sliding shaft 409 to generate displacement.

[0085] The first sliding shaft 409 slides within the second sliding groove 402c, while simultaneously applying a downward force to the second car logo connecting rod 402, causing the second car logo connecting rod 402 to rotate around the hinge point between itself and the mounting base 101, thereby driving the car logo assembly 3 to descend along a set path.

[0086] During the above transmission and movement process, the pressure rod 406 continuously applies a downward force to the second logo connecting rod 402, causing the first sliding shaft 409 to remain under stress within the second sliding groove 402c, and the second sliding shaft 4010 to remain under stress within the first sliding groove 403b on the rocker arm 403. When the second logo connecting rod 402 rotates to the limiting block 103, it cannot continue to move downward due to the obstruction of the limiting block 103.

[0087] At this point, the first transmission rod 404 can no longer drive the second logo connecting rod 402 to move, but the rotary drive unit 2 continues to output power, driving the connecting rod 201 to continue driving the rocker arm 403 to move. At this time, using the first sliding groove 403b on the rocker arm 403, the rocker arm 403 can slide relative to the second sliding shaft 4010 until it slides to the other end of the first sliding groove 403b. Finally, the rotary drive unit 2 stops moving, thus completing the process of the logo 303 descending and retracting.

[0088] Based on the above description of the movement process of the logo component 3 and the drive mechanism 4, it is worth noting that when the logo component 3 is raised under the control of the vehicle controller, especially in the initial stage of the upward movement, the second sliding shaft 4010 in the first slide groove 403b can slide along the first slide groove 403b. Therefore, in the initial stage, the rocker arm 403 cannot drive the second sliding shaft 4010 to move, that is, the logo component 3 is in a stationary state at this time. As the rotary drive unit 2 continuously outputs driving force, one end of the first slide groove 403b abuts against the second sliding shaft 4010, which then drives the logo component 3 to move.

[0089] At this time, the rocker arm 403 drives the first transmission rod 404 to rotate, and the first sliding shaft 409 can slide in the second sliding groove 402c on the second logo connecting rod 402, which can prevent the first transmission rod 404, the second logo connecting rod 402 and the mounting base 101 from forming a stable triangle, causing the transmission mechanism to be unable to move.

[0090] The drive mechanism 4 in this embodiment adopts the above design. Under the drive of the rotary drive unit 2, the transmission component 40 and the car logo linkage drive the car logo component 3 to rise and fall. Compared with the car logo lowering method in the prior art, it can avoid the deformation or damage of parts caused by excessive driving force, which is conducive to improving the quality of use of the lifting car logo.

[0091] Example 2

[0092] This embodiment relates to a retractable car emblem, which includes a mounting base 1 and an emblem assembly 3, as well as the driving mechanism 4 described in the first embodiment above.

[0093] As one exemplary implementation, such as Figure 14As shown, the car logo component 3 in this embodiment may include, for example, a car logo bracket 301, a base 302 disposed on the car logo bracket, and a car logo 303 disposed on the car logo bracket 301 through the base 302.

[0094] At this point, it is understandable that the base 302 serves a decorative purpose, ensuring a better appearance for the logo 303 when the logo component 3 is in the raised state. Furthermore, by using the base 302, compared to molding the surface on top of the logo bracket 301, the design and molding difficulty is significantly reduced, thus contributing to a lower manufacturing cost for the logo component 3.

[0095] In this embodiment, a car logo bracket hinge hole 301a is provided on the car logo bracket 301. There are two car logo bracket hinge holes 301a arranged vertically and spaced apart, and they are used to hinge with the first car logo connecting rod 401 and the second car logo connecting rod 402 respectively.

[0096] In addition, continue to combine Figure 15 As shown, in this embodiment, the base 302 can be connected to the logo bracket 301 via a snap-fit ​​method using the base claw 302a located thereon and the matching structure on the logo bracket 301. Using a snap-fit ​​method to connect the base 302 and the logo bracket 301 has advantages such as simple structure, low cost, and convenient assembly and disassembly.

[0097] In specific implementation, the matching structure on the aforementioned logo bracket 301 can generally be a locking hole formed on the logo bracket 301, into which the base claw 302a is vertically inserted. Furthermore, after the base 302 and the logo bracket 301 are engaged, the base 302 is preferably capable of moving up and down relative to the logo bracket 301. To allow for adjustable gap between the two, a support spring 304 can also be provided between the base 302 and the logo bracket 301.

[0098] The aforementioned support springs 304 can be multiple, distributed at different positions, to ensure that the base 302 is in the designed posture. Moreover, to ensure the stability of each support spring 304, in specific implementations, receiving grooves for accommodating the ends of the support springs 304, or protrusions for the support springs 304 to be sleeved on, can also be provided on the base 302 and the logo bracket 301 to limit the support springs 304 and prevent their position from shifting.

[0099] In this embodiment, the connection between the base 302 and the logo bracket 301 is still taken as an example. In specific implementation, in order to prevent the base 302 from separating from the logo bracket 301 due to the weak strength of the base claw 302a and its matching structure.

[0100] As a preferred embodiment, a guide structure can also be provided between the base 302 and the logo bracket 301 to guide the relative movement of the two.

[0101] As a feasible implementation, the aforementioned guiding structure may include, for example, a guide post disposed on one of the base 302 and the logo bracket 301, and a guide hole disposed on the other of the base 302 and the logo bracket 301, which matches the guide post. The guide post, inserted into the guide hole, guides the sliding of the base 302 relative to the logo bracket 301, thereby reducing the risk of deformation or breakage of the base claw 302a and its matching structure.

[0102] The lifting car logo of this embodiment adopts the car logo lifting drive mechanism in Embodiment 1. The lifting of the car logo component 3 can be achieved by the rotation drive unit 2. This avoids the situation where the product parts are easily deformed or damaged by the existing car logo lowering drive method. At the same time, the setting of the base 302 can also improve the appearance quality of the car logo component 3, thereby improving the quality of use of the lifting car logo.
