[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be understood as limiting the present application.

[0025] In order to enable those skilled in the art to better understand the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0026] See also Figure 1 The embodiment of the present application provides a car key 10, which can be applied to a vehicle. For example, the vehicle may include a car and a car key 10. The car key 10 can control the unlocking, locking, opening the trunk, closing the trunk, searching for the car, and checking the status of the car, etc.

[0027] See also Figures 2 to 5 The car key 10 includes a housing 100, a crankshaft drive device 200, a crank transmission mechanism 300, a first walking leg 400, and a second walking leg 500. The crankshaft drive device 200 and the crank transmission mechanism 300 are both disposed within the housing 100. The crankshaft transmission mechanism 300 is connected to the crankshaft drive device 200, so that the crankshaft drive device 200 can control the movement of the crankshaft transmission mechanism 300, for example, the crankshaft drive device 200 can control the crankshaft transmission mechanism 300 to rotate back and forth.

[0028] The first walking leg 400 and the second walking leg 500 are both connected to the crankshaft transmission mechanism 300. The crankshaft driving device 200 is used to control the first walking leg 400 and the second walking leg 500 to swing and walk alternately relative to the shell 100 through the crankshaft transmission mechanism 300. In this way, when the crankshaft driving device 200 controls the crankshaft transmission mechanism 300 to rotate, it drives the first walking leg 400 and the second walking leg 500 to swing and walk alternately, thereby driving the car key 10 to move, so that in addition to the practical function of the car key 10, the car key 10 also has the flexibility of a robot, which increases the fun of the car key 10 and expands the use function of the car key 10. In addition, the car key 10 can also be used as an optional accessory when the vehicle is sold to meet the different needs of users.

[0029] The crankshaft transmission mechanism 300 may include a plurality of crankshafts to drive the first walking leg 400 and the second walking leg 500 to swing and walk alternately.

[0030] Specifically, in some embodiments, the crankshaft transmission mechanism 300 may include a first crankshaft 310 and a second crankshaft 330, each of which is rotatably connected to the housing 100. The crankshaft drive device 200 is used to drive the first crankshaft 310 and the second crankshaft 330 to rotate. For example, a first mounting bracket 101 and a second mounting bracket 103 are protruding from the housing 100 and are oppositely disposed. The first crankshaft 310 and the second crankshaft 330 are rotatably connected to the first mounting bracket 101 and the second mounting bracket 103 at their ends, respectively. The connection method may be a hole-shaft connection, a bearing connection, etc. The rotation axis of the first crankshaft 310 and the rotation axis of the second crankshaft 330 may be substantially parallel. The first crankshaft 310 and the second crankshaft 330 may be arranged along the length of the car key 10, or the first crankshaft 310 and the second crankshaft 330 may be arranged along the width of the car key 10.

[0031] The first walking leg may include a plurality of first walking legs 410, the second walking leg 500 may include a plurality of second walking legs 510, the first crankshaft 310 includes a first crank rod 311 and a second crank rod 313 with a phase difference of 180 degrees, at least two of the plurality of first walking legs 410 are connected to the first crank rod 311, for example, at least two of the plurality of first walking legs 410 are rotatably connected to the first crank rod 311; at least one of the plurality of second walking legs 510 is connected to the second crank rod 313, for example, the plurality of second walking legs 510 At least one of the plurality of first walking legs 410 is rotatably connected to the second crank link 313; the second crankshaft 330 includes a third crank link 331 and a fourth crank link 333 with a phase difference of 180 degrees; at least two of the plurality of second walking legs 510 are connected to the third crank link 331, for example, at least two of the plurality of second walking legs 510 are rotatably connected to the third crank link 331; and at least one of the plurality of first walking legs 410 is connected to the fourth crank link 333, for example, at least one of the plurality of first walking legs 410 is rotatably connected to the fourth crank link 333. In this way, the first walking leg 400 includes at least three first walking legs 410, and the three first walking legs 410 can be arranged in a triangle. The second walking leg 500 includes at least three second walking legs 510, and the three second walking legs 510 can be arranged in a triangle. This allows the first walking legs 410 and the second walking legs 510 to stably support the housing 100, thereby allowing the car key 10 to move stably.

[0032] In addition, the first curved rod 311 and the fourth curved rod 333 have the same phase angle, and the second curved rod 313 and the third curved rod 331 have the same phase angle. In this way, multiple first walking feet 410 are connected to the first curved rod 311 and the fourth curved rod 333 with the same phase angle, and multiple second walking feet 510 are connected to the second curved rod 313 and the third curved rod 331 with the same phase angle, so that the first walking foot 410 and the second walking foot 510 can swing periodically, and the interval landing time of the first walking foot 410 and the second walking foot 510 is equal, so that the car key 10 can move stably, which helps to avoid the car key 10 from moving unsteadily due to the different phase difference of the crankshaft when the first walking foot 410 and the second walking foot 510 swing.

[0033] Among them, the number of the first curved rod 311, the second curved rod 313, the third curved rod 331 and the fourth curved rod 333 can all be multiple. For the convenience of description, the following example is used to explain that the number of the first curved rod 311 and the third curved rod 331 are both two, the number of the second curved rod 313 and the fourth curved rod 333 are both one, the two first curved rods 311 are named the first rod 3111 and the third rod 3113 respectively, and the two third curved rods 331 can be named the fifth rod 3311 and the sixth rod 3313 respectively.

[0034] The first crankshaft 310 may include a first connecting rod, a first rod 3111, a second curved rod 313, and a third rod 3113. The first connecting rod may include a first rotating portion and a second rotating portion having the same central axis. The first rotating portion and the second rotating portion are both rotatably connected to the housing 100. The first rod 3111, the second curved rod 313, and the third rod 3113 are sequentially connected between the first rotating portion and the second rotating portion. The second curved rod 313 is located on one radial side of the first connecting rod, and the first rod 3111 and the third rod 3113 are located on the other radial side of the first connecting rod. This means that there is a 180-degree phase difference between the first rod 3111 and the second curved rod 313, and there is also a 180-degree phase difference between the third rod 3113 and the second curved rod 313. The phase angles of the first rod 3111 and the third rod 3113 are the same. The structure of the second crankshaft 330 may be the same as that of the first crankshaft 310. The first crankshaft 310 and the second crankshaft 330 may be symmetrically distributed. For example, the second crankshaft 330 may include a second connecting rod, a fifth rod 3311, a fourth curved rod 333 and a sixth rod 3313, wherein the second connecting rod may include a third rotating portion and a fourth rotating portion with the same central axis, and the third rotating portion and the fourth rotating portion may be rotatably connected to the housing 100, the fifth rod 3311, the fourth curved rod 333 and the sixth rod 3313 are sequentially connected between the third rotating portion and the fourth rotating portion, and the fourth curved rod 333 is located on one side of the second connecting rod in the radial direction, and the fifth rod 3311 and the sixth rod 3313 are both located on the other side of the second connecting rod in the radial direction, that is, the fifth rod 3311 and the fourth curved rod 333 have a phase difference of 180 degrees, the sixth rod 3313 and the fourth curved rod 333 also have a phase difference of 180 degrees, and the phase angles of the fifth rod 3311 and the sixth rod 3313 are the same. The first rod 3111 , the third rod 3113 , and the fourth curved rod 333 have the same phase angle, and the second curved rod 313 , the fifth rod 3311 , and the sixth rod 3313 have the same phase angle.

[0035] As an example, for ease of understanding, the first walking leg 400 includes three first walking legs 410, which are respectively named as the first leg 411, the second leg 413, and the third leg 415, and the second walking leg 500 includes three second walking legs 510, which are respectively named as the fourth leg 511, the fifth leg 513, and the sixth leg 515. The first leg 411 can be connected to the first rod 3111, the second leg 413 can be connected to the third rod 3113, the third leg 415 can be connected to the fourth curved rod 333, the fourth leg 511 can be connected to the fifth rod 3311, the fifth leg 513 can be connected to the second curved rod 313, and the sixth leg 515 can be connected to the sixth rod 3313. When the first crankshaft 310 and the second crankshaft 330 swing back and forth, they drive the first foot 411, the second foot 413, the third foot 415, the fourth foot 511, the fifth foot 513 and the sixth foot 515 to swing back and forth. At this time, the first foot 411, the third foot 415 and the fifth foot 513 have the same swinging direction, the second foot 413, the fourth foot 511 and the sixth foot 515 have the same swinging direction, and the interval landing time of the first walking foot 410 and the second walking foot 510 is equal, so that the car key 10 can move stably, which helps to avoid the car key 10 from moving unsteadily due to the different phase difference of the crankshafts when the first walking foot 410 and the second walking foot 510 swing.

[0036] It can be understood that due to the structural characteristics of the above-mentioned crankshaft, when the first foot 411, the third foot 415 and the fifth foot 513 land, the distance between the second foot 413, the fourth foot 511 and the sixth foot 515 and the end away from the shell 100 is shortened, which helps to avoid the second foot 413, the fourth foot 511 and the sixth foot 515 from contacting the landing surface and interfering with the swinging of the first foot 411, the third foot 415 and the fifth foot 513; when the second foot 413, the fourth foot 511 and the sixth foot 515 land, the distance between the first foot 411, the third foot 415 and the fifth foot 513 and the end away from the shell 100 is shortened relative to the shell 100, which helps to avoid the first foot 411, the third foot 415 and the fifth foot 513 from contacting the landing surface and interfering with the swinging of the second foot 413, the fourth foot 511 and the sixth foot 515.

[0037] In some embodiments, the ends of the first and second walking legs 410 and 510 that extend away from the housing 100 may be curved. For example, the ends of the first and second walking legs 410 and 510 that extend away from the housing 100 may be spherical. This allows the first and second walking legs 410 and 510 to rotate smoothly relative to the landing surface as they alternately swing and walk on it, helping to prevent interference between the first and second walking legs 410 and 510 and the landing surface, which could affect the smooth movement of the car key 10. The landing surface may be the ground, a tabletop, or the like. The first and second walking legs 410 and 510 may be roughly cylindrical in shape.

[0038] In some embodiments, the first crankshaft 310 and the second crankshaft 330 can be driven independently by different driving members. For example, the crankshaft drive device 200 may include a first crankshaft drive member and a second crankshaft drive member. The driving end of the first crankshaft drive member may be connected to one end of the first crankshaft 310, and the first crankshaft drive member may drive the first crankshaft 310 to swing back and forth, thereby driving the first walking leg 400 to swing back and forth. The driving end of the second crankshaft drive member may be connected to one end of the second crankshaft 330, and the driving end of the second crankshaft drive member may be connected to one end of the second crankshaft 330, and the second crankshaft drive member may drive the second crankshaft 330 to swing back and forth, thereby driving the second walking leg 500 to swing back and forth. The first crankshaft drive member and the second crankshaft drive member can be started and stopped simultaneously, thereby controlling the first crankshaft 310 and the second crankshaft 330 to rotate and stop simultaneously, so that the car key 10 can move stably.

[0039] In addition, the first crankshaft 310 and the second crankshaft 330 may also be driven by one driving member.

[0040] Specifically, in some embodiments, the crankshaft transmission mechanism 300 may further include a third crankshaft 350 and a phase synchronization rod 370. The third crankshaft 350 is rotatably connected within the housing 100 and positioned between the first crankshaft 310 and the second crankshaft 330. The first crankshaft 310, the third crankshaft 350, and the second crankshaft 330 are all rotatably connected to the phase synchronization rod 370. Specifically, the first crankshaft 311, the third crankshaft 350, and the fourth crankshaft 333 are all rotatably connected to the phase synchronization rod 370. In this way, the phase synchronization rod 370 can ensure that the phases of the first crankshaft 311 and the fourth crankshaft 333 are always consistent, and that the phases of the second crankshaft 313 and the fourth crankshaft 333 are always consistent, thereby ensuring that the landing intervals of the first and second walking legs 400 are equal, allowing the vehicle key 10 to move stably. Alternatively, the second crankshaft 313, the third crankshaft 350, and the third crankshaft 331 are all rotatably connected to the phase synchronization rod 370.

[0041] In some embodiments, the third crankshaft 350 may include a third connecting rod and a seventh curved rod 3313 connected thereto. The third connecting rod may include a fifth rotating portion and a sixth rotating portion having the same central axis. Both the fifth rotating portion and the sixth rotating portion are rotatably connected to the housing 100. The seventh curved rod 3313 is connected between the fifth rotating portion and the sixth rotating portion and is located on one radial side of the third connecting rod. The seventh curved rod 3313 and the second curved rod 313 have the same phase angle, or the seventh curved rod 351 and the fourth curved rod 333 have the same phase angle. The phase synchronization rod 370 may include a first connecting portion, a second connecting portion, and a third connecting portion connected in sequence, wherein the first connecting portion and the second connecting portion are substantially parallel and have a distance difference. The first connecting portion is rotatably connected to the second curved link 313, the second connecting portion is rotatably connected to the third curved link 351, and the third connecting portion is rotatably connected to the seventh curved link 3313. In this way, the phase synchronization lever 370 can ensure that the phases of the second curved link 313 and the third curved link 331 are always consistent, and the phases of the first curved link 311 and the fourth curved link 333 are always consistent, thereby ensuring stable movement of the car key 10. Alternatively, the first connecting portion can be rotatably connected to the first curved link 311, the second connecting portion can be rotatably connected to the seventh curved link 351, and the third connecting portion can be rotatably connected to the fourth curved link 333.

[0042] In some embodiments, the crankshaft drive device 200 may include a crankshaft drive member 210, a drive gear 230, and a driven gear 250. The drive end of the crankshaft drive member 210 is connected to the drive gear 230 and drives the drive gear 230 to rotate. The driven gear 250 is connected to one end of the first crankshaft 310, and the drive gear 230 and the driven gear 250 are meshed. In this way, the crankshaft drive member 210 drives the gear structure to drive the first crankshaft 310 to rotate, which can make the rotation of the first crankshaft 310 more stable, thereby allowing the car key 10 to move stably.

[0043] The crankshaft driving component 210 may be a driving motor, a steering gear or other driving devices.

[0044] In some embodiments, the crankshaft drive device 200 may further include a linkage gear 270, which is respectively engaged with the driving gear 230 and the driven gear 250. In this way, by engaging the linkage gear 270 between the driving gear 230 and the driven gear 250, the transmission of the gear structure is helped to be more stable. In addition, the linkage gear 270 can also adjust the output torque of the crankshaft drive 210, further increasing the stability of the gear structure transmission.

[0045] In some embodiments, the driving gear 230, the linkage gear 270, and the driven gear 250 can be arranged sequentially along the direction from the first crankshaft 310 to the second crankshaft 330. This helps reduce the duty cycle of the driving gear 230, the linkage gear 270, and the driven gear 250, thereby increasing the utilization of the space within the housing 100. For example, the driving gear 230, the linkage gear 270, and the driven gear 250 can be located between the first mounting bracket 101 and the side wall of the housing 100.

[0046] In some embodiments, the car key 10 may further include a slider 700 and a slider driving device 600. The slider 700 is slidably positioned within the housing 100. For example, a sliding groove 105 is provided on opposing sides of the first mounting bracket 101 and the second mounting bracket 103. The slider 700 includes a connected slider body 701 and a sliding connection portion 703. The sliding connection portion 703 is slidably connected within the sliding groove 105. When the sliding connection portion 703 slides within the sliding groove 105, it drives the slider 700 to slide relative to the housing 100. The sliding groove 105 may include a sliding space, a first opening, and a second opening that are interconnected. The first opening is located at the ends of the first mounting bracket 101 and the second mounting bracket 103 to facilitate the installation of the slider 700. The second opening is located on the opposite side of the first mounting bracket 101 and the second mounting bracket 103. The width of the second opening can be smaller than the width of the sliding space, so that the slider 700 can slide stably in the sliding groove 105, which helps to prevent the slider 700 from detaching from the sliding groove 105 from the second opening. For example, the cross-sectional shape of the sliding groove 105 can be roughly trapezoidal.

[0047] The first crankshaft 310, the second crankshaft 330, and the third crankshaft 350 are all rotatably connected to the slider 700. Specifically, the first crankshaft 310, the second crankshaft 330, and the third crankshaft 350 are all rotatably connected to the slider body 701. The slider drive device 600 is used to control the slider 700 to slide relative to the housing 100 and drive the first walking leg 400 and the second walking leg 500 to extend or retract relative to the housing 100. In this way, when the slider 700 slides within the sliding groove 105, it can drive the crankshaft transmission mechanism 300 to move relative to the housing 100, thereby driving the first walking leg 400 and the second walking leg 500 to extend or retract relative to the housing 100. When the first walking leg 400 and the second walking leg 500 are retracted relative to the shell 100, the portability of the car key 10 is improved; when the first walking leg 400 and the second walking leg 500 are extended relative to the shell 100, the first walking leg 400 and the second walking leg 500 can swing and walk alternately relative to the shell 100, thereby driving the car key 10 to move.

[0048] In some embodiments, the slider drive device 600 may include a slider drive member 610 and a connecting arm 630. The connecting arm 630 is connected to the driving end of the slider drive member 610. The connecting arm 630 is provided with a sliding groove 631. A sliding portion 710 is protruding from the side of the slider 700 facing away from the crankshaft transmission mechanism 300. Specifically, the sliding portion 710 is connected to the slider body 701. The sliding portion 710 is slidably located in the sliding groove 631. The rotation of the connecting arm 630 drives the sliding portion 710 to slide in the sliding groove 631, thereby driving the slider 700 to slide relative to the housing 100. Thus, when the slider driver 610 drives the connecting arm 630 to rotate in a first direction and the sliding portion 710 slides in the sliding groove 631, the slider 700 slides relative to the housing 100, thereby causing the first and second walking legs 400 and 500 to retract relative to the housing 100, making it easier for the user to carry the car key 10. When the slider driver 610 drives the connecting arm 630 to rotate in a second direction and the sliding portion 710 slides in the sliding groove 631, the slider 700 slides relative to the housing 100, thereby causing the first and second walking legs 400 and 500 to extend relative to the housing 100, allowing the first and second walking legs 400 and 500 to alternately swing and move relative to the housing 100, thereby moving the car key 10. The first and second directions are opposite.

[0049] The slider driving component 610 may be a driving motor, a steering gear or other driving components.

[0050] In some embodiments, the vehicle key 10 may further include a connecting plate 800. The connecting plate 800 is located within the housing 100 and connected to the slider 700. The crankshaft drive 200 is connected to the connecting plate 800. As a result, when the slider 700 slides, it simultaneously drives the crankshaft drive 200 and the crank transmission mechanism 300, helping to ensure normal transmission between the crankshaft drive 200 and the crank transmission mechanism 300. For example, the connecting plate 800 may include a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate being arranged at an angle, such as a 90-degree angle between the first connecting plate and the second connecting plate. The driving gear 230, the driven gear 250 and the linkage gear 270 can all be rotatably connected to the first connecting plate. Specifically, the driving gear 230 can be rotatably connected between the crankshaft driving member 210 and the first connecting plate, the linkage gear 270 can be rotatably connected between the slider 700 and the first connecting plate, and the driven gear 250 can be rotatably connected between the first crankshaft 310 and the first connecting plate.

[0051] In some embodiments, the car key 10 may further include a control panel and control buttons. The control panel may be disposed within the housing 100. For example, the control panel may be disposed above the slider drive member 610. The control panel may be connected to the crankshaft drive device 200, the slider drive device 600, and the control buttons. The connection may be electrical, signal, or the like. The control buttons may be exposed on the car key 10 for easy operation by the user. There may be multiple control buttons, each of which may perform different control functions. For example, the control buttons may control unlocking and locking the car, opening and closing the trunk, finding the car, checking the status of the car, controlling the deformation of the car key 10, and controlling the movement of the car key 10. Controlling the deformation of the car key 10 means that the control button may control the extension of the first walking leg 400 and the second leg intended to move relative to the housing 100, and the control button may control the retraction of the first walking leg 400 and the second leg intended to move relative to the housing 100.

[0052] In some embodiments, the car key 10 may further include a battery, which is disposed in the housing 100 and can be electrically connected to the control board, the crankshaft drive device 200 , and the slider drive device 600 to provide electrical energy to the control board, the crankshaft drive device 200 , and the slider drive device 600 .

[0053] See also Figure 3 and Figure 5 In some embodiments, a stopper 110 is protruding from the housing 100. When the first walking leg 400 and the second walking leg 500 retract relative to the housing 100, the crankshaft transmission mechanism 300 or the slider 700 abuts against the stopper 110. Thus, when the slider driving device 600 drives the slider 700 to slide relative to the housing 100 and drives the first walking leg 400 and the second walking leg 500 to retract relative to the housing 100, the stopper 110 can be located in the movement path of the crankshaft transmission mechanism 300 or the movement path of the slider 700 to block the movement of the crankshaft transmission mechanism 300 or the slider 700. This helps prevent the slider 700 from disengaging from the sliding groove 105 along the sliding direction when the first walking leg 410 and the second walking leg 510 are already in the retracted state.

[0054] See also Figure 3 and Figure 6 In some embodiments, the housing 100 may have multiple through holes, with the first walking leg 400 and the second walking leg 500 respectively inserted into corresponding through holes. For example, the housing 100 may have six through holes, with the first leg 411, the second leg 413, the third leg 415, the fourth leg 511, and the sixth leg 515 respectively inserted into one of the through holes.

[0055] In some embodiments, the shell 100 includes a hole surface, which is formed around a through hole, and the hole surface is provided with a chamfer along the axial upper side of the through hole, or the hole surface is provided with a chamfer along the axial lower side of the through hole, or the hole surface is provided with chamfers along the axial upper and lower sides of the through hole. In this way, the chamfer can avoid the walking foot and help to reduce the aperture of the through hole.

[0056] In some embodiments, the housing 100 may further include a plurality of limiting bosses 120, each of which is protruding from the housing 100. The limiting bosses 120 are arranged around the through-holes, with each limiting boss 120 corresponding to each through-hole. When the first and second walking legs 400, 500 are retracted relative to the housing 100, each limiting boss 120 abuts against the corresponding first and second walking legs 400, 500. In this way, the limiting bosses 120 can limit the swinging of the first and second walking legs 400, 500, helping to prevent the first and second walking legs 400, 500 from shaking when the first and second walking legs 400, 500 are retracted, thereby affecting the user experience. For example, the limiting bosses 120 can be arranged around chamfers.

[0057] See also Figure 7 In one embodiment of the present application, a vehicle 1 is provided. Vehicle 1 includes a car 90 and a car key 10 according to any of the above embodiments. Car key 10 and car 90 are signal-connected. Thus, car key 10 can control car 90, for example, unlocking and locking car 90, opening and closing the trunk, controlling vehicle location, and checking the status of car 90. Furthermore, because vehicle 1 includes car key 10, vehicle 1 possesses all the benefits of car key 10, which will not be detailed here.

[0058] In the car key 10 and vehicle 1 provided in the embodiment of the present application, the first walking leg 400 and the second walking leg 500 are both connected to the crankshaft transmission mechanism 300, and the crankshaft driving device 200 is used to control the first walking leg 400 and the second walking leg 500 to swing and walk alternately relative to the shell 100 through the crankshaft transmission mechanism 300. In this way, when the crankshaft driving device 200 controls the crankshaft transmission mechanism 300 to rotate, it drives the first walking leg 400 and the second walking leg 500 to swing and walk alternately, thereby driving the car key 10 to move, so that in addition to the practical function of the key, the car key 10 also has the flexibility of a robot, which increases the fun of the car key 10 and expands the use function of the car key 10. In addition, the car key 10 can also be used as an optional accessory when the vehicle 1 is sold to meet the different needs of users.
