Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a decorative object telescopic mechanism and an automobile. Background Art

[0002] With the development of the automobile industry, the innovation ability of automobiles is increasing day by day. Customers not only put forward requirements on the performance of products, but also pursue more eye-catching and cool mechanisms. Take the car logo as an example. The traditional car logo is partly arranged near the front air intake grille, which has a weak three-dimensional sense; part of the car logo is arranged vertically on the engine hood, but has no lifting function; the lifting car logo is not only an eye-catching and cool vehicle mechanism, but also can highlight the presence of the brand.

[0003] In the prior art, a lifting car logo with an anti-theft function is designed, which unlocks the car logo through a rotating force transmission mechanism, and designs a rocker arm slider type moving mechanism to drive the car logo to rise; in order to avoid movement interference between the force transmission mechanism and the moving mechanism and other parts during operation, the design needs to reserve a large space; thus, the structure of the car logo retractable mechanism is relatively complex and not compact enough. Utility Model Content

[0004] In view of the deficiencies in the prior art, the first object of the present invention is to provide a decorative object telescopic mechanism, which has a simpler and more compact structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The decoration retractable mechanism comprises:

[0007] A driving unit, comprising a slide rail, a sliding member and a linear driving module for driving the sliding member to move along the slide rail, wherein the sliding member is provided with a locking groove;

[0008] The mobile unit includes a base, a support block for mounting a decoration, and a support rod and a locking block which are linearly movably connected to the base. The support rod is provided with a locking tongue which matches the locking groove. The support block is movably connected to the base so that when the decoration shakes, the support rod drives the locking block to unlock the sliding member. The structure of the mechanism is relatively simple and more compact.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] Under normal conditions, the locking block and the sliding part are locked together, and the linear drive module can drive the mobile unit to move upward or downward as needed, thereby realizing the telescopic function of the decoration; when the decoration is shaken by external force, the support rod is driven by the pressure of the decoration to make the locking block move linearly until it exits the lock with the sliding part and completes the unlocking. At this time, the mobile unit is retracted into the car as a whole to prevent theft.

[0011] On the one hand, first of all, the locking block only needs linear movement to complete locking and unlocking. Compared with the existing rotary force transmission mechanism, the movement process is simplified, resulting in fewer parts and a simpler structure. In addition, there is no need to reserve space for the rotation of the force transmission mechanism in the layout, and the structure is more compact. Similarly, a linear drive module is used to drive the sliding part and the locking block to move together. The movement trajectory and structure of the drive module are simpler than the existing rocker arm slider type, and there is no need to reserve space for the rotation of the rocker arm slider in the layout, and the structure is more compact.

[0012] On the other hand, since the linear motion stroke of the locking block of the utility model is smaller than the motion stroke of the rotary force transmission mechanism when unlocking / locking, the driving force required for resetting the locking block is smaller than that of the rotary force transmission mechanism, that is, the impact force of the locking block on the sliding member cooperating therewith is smaller, thereby making the sliding member thinner and the structure more compact.

[0013] Furthermore, the slide rail extends vertically, the support rod can move vertically, and the locking block can move approximately horizontally.

[0014] Furthermore, the support rod and the locking block are connected via an inclined surface so that the support rod drives the locking block to move.

[0015] Furthermore, the sliding member is provided with a locking groove, the locking block is provided with a driving groove, and the support rod is fixedly provided with a sliding rod that can slide along the driving groove so that the locking block can withdraw from the locking groove.

[0016] Furthermore, the support rod is elastically connected inside the base.

[0017] Furthermore, the linear drive module includes: a driven wheel, a motor, a driving wheel driven by the motor, and a transmission member for connecting the driving wheel and the driven wheel, the transmission member is tensioned by the driving wheel and the driven wheel, and the transmission member is connected to the sliding member to drive the sliding member to slide along the slide rail.

[0018] Furthermore, it also includes a tensioning module for auxiliary tensioning, and the transmission member includes a first section and a second section, both of which have one end fixedly connected to the driving wheel, the other end of the first section bypasses the driven wheel and is elastically connected to the tensioning module, and the other end of the second section is elastically connected to the tensioning module and is opposite to the direction of the first section.

[0019] Furthermore, it also includes a pulling module, and when the locking block and the sliding member are unlocked, the pulling module drives the moving unit to move downward.

[0020] Furthermore, a cover for closing the aperture is further included, wherein the cover is arranged such that when the decoration is retracted into the aperture, the cover can be driven by the moving unit to close the aperture.

[0021] The second object of the utility model is to provide a car whose decoration retractable mechanism has a simpler and more compact structure.

[0022] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0023] A car comprises any of the above-mentioned decorative object telescopic mechanisms.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] Since the automobile adopts the above-mentioned decoration extension and retraction mechanism, the movement process of the mechanism is optimized and the structure is simpler and more compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments; the structures described in the various embodiments can be freely combined without any conflict in structure or principle.

[0046] The following is a description of some embodiments of the present invention in conjunction with the accompanying drawings:

[0047] like Figures 1 to 10As shown, the utility model proposes a decoration telescopic mechanism, including: a driving unit and a moving unit 3, wherein, for ease of understanding, the decoration 1 telescopic mechanism is specifically applied to a car, and the decoration 1 is set in the shape of a car logo, forming the most common car logo that can be lifted up and down; specifically, the decoration 1 telescopic mechanism is arranged in a car engine compartment, the car engine compartment is provided with a space for the decoration 1 to move up and down, and the car engine compartment cover 12 is also provided with an opening for the decoration 1 to extend / retract (not shown in the figure).

[0048] See also Figure 2 and Figure 3 The driving unit includes a slide rail 4, a sliding member 5 and a linear driving module 2. The extension direction of the slide rail 4 depends on the required extension direction of the decoration 1. In this embodiment, the slide rail 4 is arranged to extend vertically; the sliding member 5 is configured to be movable along the slide rail 4; the linear driving module 2 is connected to the sliding member 5 to drive the sliding member 5 to move upward or downward.

[0049] Please combine Figure 4 As shown, the mobile unit 3 includes a base 301, a support block 302, a support rod 303 and a locking block 304; wherein, in order to make the structure more compact and beautiful, a first cavity and a second cavity are provided in the base 301, and the support rod 303 is vertically movably connected in the first cavity of the base 301; in order to enable the locking block 304 to slide smoothly, the locking block 304 is generally horizontal (i.e. Figure 4 The support block 302 is movably connected to the second cavity of the base 301 in the left and right directions, and the direction has an angle with the horizontal line; the locking block 304 and the sliding member 5 are configured to be lockable or unlockable; the top end of the support block 302 is fixedly connected to the decoration 1, and the bottom end of the support block 302 is movably connected to the base 301, so that when the decoration 1 shakes, the support rod 303 can drive the locking block 304 and the sliding member 5 to unlock.

[0050] Under normal conditions, Figure 5 As shown, the locking block 304 and the sliding member 5 are locked together, and the linear drive module 2 can drive the moving unit 3 to move upward or downward as needed; Figure 4 As shown, when the decoration 1 is shaken by external force, the support rod 303 moves downward under the pressure of the decoration 1, so that the locking block 304 moves linearly until it exits the lock with the sliding member 5 and completes unlocking; Figure 1 and Figure 6 As shown, at this time, the mobile unit 3 as a whole retracts into the engine compartment of the car under its own weight or external force to avoid damage or theft. In addition to having an anti-theft function, the telescopic mechanism also has the following beneficial effects:

[0051] On the one hand, firstly, the locking block 304 can complete locking and unlocking only by linear movement. Compared with the existing rotary force transmission mechanism, the movement process is simplified, resulting in fewer parts and a simpler structure, which is convenient for manufacturing and control, and the unlocking is smoother; in addition, there is no need to reserve space for the rotation of the force transmission mechanism in the layout, and the structure is more compact; similarly, a linear drive module 2 is used to drive the sliding member 5 and the locking block 304 to move together, and the movement trajectory and structure of the drive module are simpler than the existing rocker arm slider type, and there is no need to reserve space for the rotation of the rocker arm slider in the layout, and the structure is more compact.

[0052] On the other hand, since the linear motion stroke of the locking block 304 of the utility model is smaller than the motion stroke of the rotary force transmission mechanism when unlocking / locking, the driving force required for resetting the locking block 304 is smaller than that of the rotary force transmission mechanism, that is, the impact force of the locking block 304 on the sliding member 5 cooperating therewith is smaller, thereby making the sliding member 5 thinner and the structure more compact.

[0053] Furthermore, the lock block 304 and the sliding member 5 can be connected by an electronic lock or a mechanical lock. Taking a mechanical lock as an example, Figure 3 and Figure 4 As shown, a locking tongue 3041 is provided at one end of the locking block 304, and the sliding member 5 is provided with a locking groove 501 matching the shape of the locking tongue 3041. When the locking tongue 3041 is inserted into the locking groove 501, the locking block 304 and the sliding member 5 are locked, and when the locking tongue 3041 withdraws from the locking groove 501, the locking block 304 and the sliding member 5 are unlocked; when the decorative object 1 is shaken by an external force, the support rod 303 can be driven to move downward, so that the locking tongue 3041 withdraws from the locking groove 501, and the locking block 304 and the sliding member 5 are unlocked. At this time, the base 301 drives the decorative object 1 to move downward and retract together, thereby realizing an anti-theft function; more specifically, the locking groove 501 is configured as a groove roughly in the shape of a cross, and the corresponding locking tongue 3041 is also configured as a protrusion roughly in the shape of a cross, so that the locking tongue 3041 will not shake when inserted into the locking groove 501, and the locking is stable. Preferably, the four ends of the lock slot 501 are also provided with wedge-shaped surfaces for guidance, so that the lock tongue 3041 can be smoothly inserted into the lock slot 501 or removed from the lock slot 501 .

[0054] In some other embodiments, such as Figure 4As shown, in order to enable the support rod 303 to feel more sensitively when the ornament 1 is shaken by external force, a connecting head 6 and an enlarger 7 are further provided, the connecting head 6 contacts / connects with the top end of the support rod 303, and the enlarger 7 is fixedly connected to the bottom end of the support block 302; preferably, the connecting head 6 and the enlarger 7 are both disc-shaped, the diameter of the connecting head 6 is larger than the diameter of the support rod 303, and the diameter of the enlarger 7 matches the diameter of the connecting head 6; in this way, the connecting head 6 and the enlarger 7 serve as intermediate parts, which greatly increase the contact area between the two compared to the direct contact between the support block 302 and the top end of the support rod 303, thereby making it easier to drive the support rod 303 to move downward when the ornament 1 shakes.

[0055] As a preference, Figure 7 As shown, guide surfaces 502 are further provided at the upper and lower ends of the sliding member 5 , and the guide surfaces 502 are used to allow the locking tongue 3041 to be smoothly inserted into the locking groove 501 when the sliding member 5 moves upward or downward to the position of the locking block 304 .

[0056] By adopting the above scheme, when the ornament 1 is shaken by external force, the ornament 1 causes the enlarging member 7 to tilt up through the support block 302, thereby driving the connecting head 6 to drive the support rod 303 to move downward, so that the locking tongue 3041 exits the locking slot 501, thereby realizing the anti-theft function; when it is necessary to drive the ornament 1 to move upward again, the linear drive module 2 drives the sliding member 5 to move downward until the locking tongue 3041 is reinserted into the locking slot 501, and the base 301 and the sliding member 5 can be locked again. At this time, the linear drive module 2 can drive the ornament 1 to move upward; unlocking and re-locking are very convenient.

[0057] Furthermore, if Figure 4 , Figure 8 and Fig. 9 As shown, in order to conveniently connect the support block 302 to the base 301, the base 301 is configured to include a main body 3011 and a fixed block 3012 detachably connected to the main body 3011, and a channel is provided in the middle of the fixed block 3012, and the bottom end of the support block 302 passes through the channel and is loosely matched with the channel, and the outer contour of the support block 302 can be set to be loosely matched with the channel; a mounting column is fixedly provided at the bottom of the support block 302, and the enlarger 7 is detachably connected to one end of the support block 302 passing through the channel (i.e., the mounting column) by a fastener (screws / bolts, etc.), and the fastener is coaxially arranged with the mounting column; illustratively, a plurality of connecting parts with internal threads are provided at the bottom of the fixed block 3012, and a hollow column corresponding to the connecting part is provided on the main body 3011.

[0058] During assembly, first pass the support block 302 through the channel of the fixed block 3012 and use fasteners to connect the support block 302 and the enlarger 7 together, then pass the screws / studs through the hollow column and threadedly connect them to the connecting part, so as to install the fixed block 3012 on the top of the main body 3011; the installation of the decorative object 1 and the mobile unit 3 is completed.

[0059] Furthermore, if Figure 4 As shown, in order to enhance the movement stability of the mechanism, a first guide ring 8 and a second guide ring 9 distributed up and down are fixed in the base 301, wherein the inner wall of the first guide ring 8 contacts the outer wall of the connecting head 6 to guide the connecting head 6; the second guide ring 9 is sleeved on the support rod 303 to guide the support rod 303.

[0060] Furthermore, the support rod 303 is elastically connected to the base 301 through the elastic element 305, a circular groove is provided at the bottom of the connecting head 6, a cylinder is fixed on the second guide ring 9, the elastic element 305 is sleeved outside the support rod 303, and the upper and lower ends of the elastic element 305 are respectively located in the circular groove and the cylinder, and the circular groove and the cylinder play a limiting role on the spring 1002.

[0061] In some other embodiments, the support rod 303 and the locking block 304 are arranged via an inclined surface so that the support rod 303 drives the locking block 304 to move.

[0062] Furthermore, if Figure 4 As shown, a driving groove 3042 is provided at the left end of the locking block 304. The design elements of the driving groove 3042 profile are the required stroke of the support rod 303 and the lateral displacement of the locking block 304, which determine the specific angle and length of the driving groove 3042. A sliding rod 306 is fixedly provided on the bottom end of the support rod 303, and the sliding rod 306 is configured to slide along the driving groove 3042 so that the locking block 304 can withdraw from the locking groove 501 matched therewith.

[0063] In this way, the locking block 304 and the support rod 303 have a simple structure and are connected together. Since the locking block 304 is laterally movably connected to the base 301, the mechanism composed of the connecting head 6, the support rod 303 and the locking block 304 has multiple guide limits at the top, middle and bottom, and the unlocking mechanism runs more smoothly and has a compact structure.

[0064] Preferably, when the elastic element 305 drives the connector 6 to move upward, the elastic element 305 can drive the support rod 303 to move upward synchronously, so that the top of the support rod 303 is connected to the connector 6; illustratively, a slot is provided on the connector 6, and a clamping head matching the slot is provided on the top of the support rod 303, and the clamping head is clamped in the slot to realize the clamping connection between the support rod 303 and the connector 6. In this way, only one elastic element 305 is required to drive the support rod 303 and the locking block 304 to reset, and no additional parts dedicated to the reset of the locking block 304 are required, which has a simple structure and is easy to manufacture and assemble.

[0065] Furthermore, if Figure 7 and Fig. 9 As shown, the bottom of the support rod 303 is configured as a U-shaped groove structure, and the U-shaped groove is sleeved outside the driving groove 3042 during assembly, so that the connection between the support rod 303 and the locking block 304 is more stable.

[0066] Furthermore, the driving groove 3042 can be a strip groove or an arc groove; the strip-shaped driving groove 3042 can make the roughly horizontal displacement speed of the locking block 304 consistent, and the arc-shaped driving groove 3042 can make the roughly horizontal displacement speed of the locking block 304 inconsistent, for example, first fast and then slow or first slow and then fast, and the specific shape depends on the specific unlocking requirements of the locking block 304 in practice; illustratively, the driving groove 3042 is a strip groove, and at the same time, in order to make the locking block 304 move more smoothly, the angle between the driving groove 3042 and the horizontal line is greater than or equal to 30 degrees to ensure smooth sliding of the locking block 304.

[0067] Furthermore, a guide structure is provided at one end of the support rod 303 that contacts the locking block 304 , so that when the support rod 303 moves downward, it can push the locking block 304 to move approximately in a lateral direction.

[0068] Exemplarily, a first guiding slope is provided at one end of the locking block 304, and a second guiding slope matched with the first guiding slope is provided at the bottom end of the support rod 303. The second guiding slope gradually moves downward as the support rod 303 moves downward, thereby pushing the locking block 304 to move laterally through the first guiding slope. It should be noted that, since the bottom end of the support rod 303 of this scheme (not shown in the figure) is not connected to the locking block 304, the elastic element 305 will not drive the locking block 304 to reset when pushing the support rod 303 upward when the external force is removed. Therefore, a reset mechanism is required to push the locking block 304 to reset. Exemplarily, the reset mechanism has elastic force, and the reset mechanism is arranged on the base 301 along the sliding direction of the locking block 304. After the external force is removed, the reset mechanism pushes the locking block 304 to reset. In this process, the second guiding slope acts on the first guiding slope, thereby driving the support rod 303 to move upward to reset. This scheme can cancel the elastic element 305, but the compactness of the mechanism is not as good as the above-mentioned embodiment (i.e. Figure 3 The technical solution shown).

[0069] In some other embodiments, such as Fig. 9 As shown, a groove with a T-shaped cross-section is provided on the base 301, and the locking block 304 includes a flat plate and a vertical plate fixed on the flat plate. The flat plate and the vertical plate can slide along the groove, and the driving groove 3042 is arranged at one end of the locking block 304 away from the locking tongue 3041; in this way, the base 301 can reliably limit the locking block 304, and the structural strength of the locking block 304 itself is good.

[0070] In some other embodiments, the linear drive module 2 includes an electric push rod / oil cylinder / air cylinder / reel-type transmission structure, etc. Here, the reel-type transmission structure is taken as an example. Specifically, Figure 2 and Figure 3 As shown, the linear drive module 2 includes: a driven wheel 201, a motor 202, a driving wheel 203 and a transmission member 204, wherein the motor 202 is arranged below the slide rail 4, the driving wheel 203 is assembled in the wheel seat 205, a spline is provided on the output shaft of the motor 202, and a keyway matched with the spline is provided on the inner wall of the driving wheel 203, and the motor 202 provides torque for the driving wheel 203 to drive the driving wheel 203 to rotate; the driven wheel 201 is rotatably connected to the slide rail 4 through the rotating shaft, and the driven wheel 201 is located above the driving wheel 203; the transmission member 204 is sleeved on the driving wheel 203 and the driven wheel 201, so as to be tensioned by the driving wheel 203 and the driven wheel 201; the sliding member 5 is connected to the transmission member 204 to drive the sliding member 5 to slide along the slide rail 4.

[0071] The mechanism drives the decorative object 1 to move linearly through the sliding member 5, and the motor 202 can make the decorative object 1 move at a balanced speed and run smoothly; in addition, since the mechanism does not need to rotate the rocker arm during operation, there is no need to reserve space for the rocker arm rotation in the layout, and the structure is more compact. Since the mobile mechanism adopts flexible transmission, it also reduces noise and vibration, and improves the buffering performance and service life of the mechanism.

[0072] Furthermore, the transmission member 204 includes a steel wire rope / belt / chain, etc. Preferably, the transmission member 204 is a steel wire rope.

[0073] In some other embodiments, in combination Fig.10 As shown, it also includes a tensioning module 10, the transmission member 204 includes a first section 2041 and a second section 2042, and two wire hanging grooves are provided on the driving wheel 203. One end of the first section 2041 and the second section 2042 are fixed with a joint, and the joint of the first section 2041 is clamped in the left wire hanging groove, and the joint of the second section 2042 is hung in the right wire hanging groove, so as to complete the connection between the transmission member 204 and the driving wheel 203; the specific design of the joint and the wire hanging groove can refer to the existing design, such as the patent document with announcement number CN 20205314777U / CN203531613U / CN205933026U, which will not be repeated in this article. The end of the first section 2041 away from the driving wheel 203 bypasses the driven wheel 201 and extends downward, and is finally elastically connected to the tensioning module 10. The end of the second section 2042 away from the driving wheel 203 extends upward (i.e., in the opposite direction of the first section 2041), and is finally elastically connected to the tensioning module 10.

[0074] Exemplarily, two slide grooves are provided on the sliding member 5, and the tensioning module 10 includes two groups of baffles 1001 and springs 1002 with the same structure. Taking the baffle 1001 and spring 1002 connected to the second section 2042 as an example, the baffle 1001 and the spring 1002 are both located in the slide groove and can move relative to the slide groove. The slide groove plays a guiding and limiting role for the baffle 1001 and the spring 1002 to prevent the baffle 1001 and the spring 1002 from falling out; the end of the second section 2042 facing away from the driving wheel 203 passes through the spring 1002 and is fixedly connected to the baffle 1001. Preferably, this end of the second section 2042 is welded to the baffle 1001; the diameter of the baffle 1001 is set to be greater than or equal to the inner diameter of the spring 1002, so that the baffle 1001 is pressed on the top surface of the spring 1002.

[0075] In this way, when the transmission member 204 is slightly deformed due to force during operation, since the transmission member 204 is elastically connected to the tensioning module 10, the elastic force of the spring 1002 can compensate for the gap caused by the deformation of the transmission member 204, so that the transmission member 204 always remains tensioned on the driving wheel 203 and the driven wheel 201; the tensioning module 10 plays the function of auxiliary tensioning.

[0076] Furthermore, if Fig.10 As shown, two wire hanging grooves are arranged on the front and back sides of the driving wheel 203, which improves the symmetry of the transmission member 204, makes the operation more stable and facilitates the arrangement of the first section 2041 and the second section 2042.

[0077] Furthermore, in order to make the sliding member 5 run more smoothly, the second section 2042 is set to be coaxial with the spring 1002 as much as possible; specifically, a channel is provided at the bottom end of the slide groove to avoid the second section 2042, and the baffle 1001 is set to include a head and a rod fixed thereto, the rod extends into the spring 1002 and its outer diameter matches the inner diameter of the spring 1002.

[0078] Furthermore, in order to more conveniently assemble the baffle 1001 and the spring 1002 in the slide groove, one end of the slide groove and the side away from the sliding member 5 are set to be open; it should be understood that since the side of the slide groove away from the sliding member 5 is set to be open at this time, it is necessary to set a limiting protrusion 1003 on the side wall of the slide groove to prevent the spring 1002 and the baffle 1001 from detaching from the slide groove.

[0079] Furthermore, if Figure 3 and Figure 5 As shown, a strip-shaped limiting groove is provided in the middle of the slide rail 4, the limiting groove runs through from left to right, the base 301 is slidably connected to the slide rail 4, the locking groove 501 is arranged on the side of the slide rail 4 away from the base 301, and the sliding member 5 is slidably connected in the limiting groove. In this way, the sliding member 5 and the moving unit 3 have better symmetry, a more compact structure, and a smooth operation.

When the lock tongue 3041 exits the lock slot 501, the pulling module 11 provides an external driving force, so that the mobile unit 3 drives the ornament 1 to move downward quickly until the ornament 1 is retracted into the engine compartment, so as to prevent the ornament 1 from being damaged and stolen.

[0081] In some other embodiments, such as Figure 1 and Figure 6 As shown, the base 301 further includes a cover 12 for closing the orifice. The cover 12 is configured so that when the decoration 1 is retracted into the orifice, the cover 12 can be driven by the moving unit 3 to close the orifice. For example, a linkage groove 13 is fixedly provided on one side of the base 301. The linkage groove 13 is provided with a vertical section and a horizontal section. The four connecting rods are as follows: Figure 1 The arrangement and connection shown constitutes a four-bar linkage 14, with the cover 12 mounted on one of the links, and a roller is rotatably connected to one end of the lower link.

[0082] During the downward movement of the mobile unit 3, the roller rolls along the linkage groove 13, so that the four-bar linkage 14 drives the cover 12 to move downward. Figure 1 Gradually change to Figure 6 In the state shown, the roller is located in the horizontal section of the linkage groove 13, the decoration 1 is retracted into the hole and locked in this position by the horizontal section, and the cover 12 closes the hole; similarly, if the hole needs to be reopened and the decoration 1 needs to be extended, it is only necessary for the linear drive module 2 to drive the moving unit 3 to move upward, and the linkage groove 13 can drive the four-bar linkage 14 to move upward. Figure 6 Status changes to Figure 1 state.
