Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application usually described and illustrated herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0039] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of the present application, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship in which the inventive product is usually placed during use. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0041] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0042] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0043] Please refer to Figure 1 , an embodiment of the present application provides a lifting mechanism 10, including a mounting main body 100, a movable member 200 and a lifting platform 300. The mounting main body 100 has a receiving cavity 110. The movable member 200 is movably disposed on the mounting main body 100. The movable member 200 cooperates with the lifting platform 300. The movable member 200 is used to drive the lifting platform 300 to rise to a first position or fall to a second position during the movement process. Wherein, when the lifting platform 300 is in the first position, at least part of it extends out of the receiving cavity 110, and when the lifting platform 300 is in the second position, it is located inside the receiving cavity 110.

[0044] It should be noted that the mounting main body 100 is the main part of the vehicle center console. There is a problem of insufficient space in the receiving cavity 110 inside the mounting main body 100, resulting in inconvenient placement of items. For example, when the lifting platform 300 is a cup holder structure, the depth of the cup holder structure in the receiving cavity 110 is insufficient. At this time, raising the cup holder structure out of the receiving cavity 110 can utilize the space outside the receiving cavity 110 to increase the depth of the cup holder structure for placing cups.

[0045] The movable member 200 is movable relative to the mounting main body 100. The movable member 200 can drive the lifting platform 300 to rise to a first position or fall to a second position during the movement process. The first position and the second position are two extreme positions in the movement stroke of the lifting platform 300.

[0046] When an item needs to be placed, the movable member 200 is moved relative to the mounting body 100. The movable member 200 drives the lifting platform 300 to rise to the first position. At this time, at least part of the lifting platform 300 extends out of the accommodating cavity 110, and the item can be placed on the lifting platform 300, thereby utilizing the space outside the accommodating cavity 110 and making it more convenient to place the item. When there is no item placed on the lifting platform 300, the movable member 200 can be moved relative to the mounting body 100, and the movable member 200 drives the lifting platform 300 to descend to the second position. At this time, the lifting platform 300 is located within the accommodating cavity 110.

[0047] Please refer to Figure 2 、 Figure 3 , in some embodiments, the movable member 200 includes a rotating member 210, a moving member 220, and a connecting rod 230 connected between the rotating member 210 and the moving member 220. The rotating member 210 is rotatably disposed on the mounting body 100, the moving member 220 is movably disposed on the mounting body 100, the moving member 220 cooperates with the lifting platform 300, and the rotating member 210 is used to drive the moving member 220 to move through the connecting rod 230 during rotation, and the moving member 220 is used to drive the lifting platform 300 to rise to the first position or descend to the second position during movement.

[0048] The moving member 220 can be selected as a plate member. A first rotating pin 190 is provided on the mounting body 100, and the rotating member 210 is rotatably connected to the mounting body 100 through the first rotating pin 190. The two ends of the connecting rod 230 can be respectively hinged to the rotating member 210 and the moving member 220.

[0049] During the upward stroke of the lifting platform 300, the rotating member 210 rotates in the first direction. The rotating member 210 drives the moving member 220 to move through the connecting rod 230 during rotation, and the moving member 220 drives the lifting platform 300 to rise to the first position during movement. During the downward stroke of the lifting platform 300, the rotating member 210 rotates in the second direction. The rotating member 210 drives the moving member 220 to move in the reverse direction through the connecting rod 230 during rotation, and the moving member 220 drives the lifting platform 300 to descend to the second position during movement. Among them, the first direction and the second direction are respectively one of the clockwise direction and the counterclockwise direction. In the embodiments of the present application, the first direction is taken as the clockwise direction and the second direction is taken as the counterclockwise direction as an example for illustration.

[0050] In some embodiments, a guiding track 221 is provided on one of the moving member 220 and the lifting platform 300. At least a part of the extending direction of the guiding track 221 forms an angle with the moving direction of the moving member 220. A guiding portion 310 that cooperates with the guiding track 221 is provided on the other of the moving member 220 and the lifting platform 300. The guiding portion 310 is configured to move along the guiding track 221 during the movement of the moving member 220, so that the lifting platform 300 rises to a first position or descends to a second position.

[0051] The guiding portion 310 may be a guiding shaft. The guiding shaft is adjacent to the guiding track 221 and cooperates with the guiding track 221. During the movement of the moving member 220, the guiding portion 310 moves along the guiding track 221, thereby driving the lifting platform 300 to rise to the first position or descend to the second position.

[0052] Optionally, the guiding track 221 is provided on the moving member 220, and the guiding portion 310 is provided on the lifting platform 300; alternatively, the guiding track 221 is provided on the lifting platform 300, and the guiding portion 310 is provided on the moving member 220.

[0053] Optionally, the guiding track 221 may be in the form of a guiding groove, which is opened on the moving member 220 or on the lifting platform 300. The guiding shaft extends into the guiding groove and cooperates with the guiding groove. During the movement of the moving member 220, the guiding portion 310 moves in the guiding groove, thereby driving the lifting platform 300 to rise to the first position or descend to the second position.

[0054] The guiding track 221 includes an inclined section 2211 and first and second horizontal sections 2212 and 2213 connected to both ends of the inclined section 2211. The extending direction of the inclined section 2211 forms an angle with the moving direction of the moving member 220. The extending directions of the first and second horizontal sections 2212 and 2213 are the same as the moving direction of the moving member 220. The guiding portion 310 is configured to move from the first horizontal section 2212 to the second horizontal section 2213 during the movement of the moving member 220, so that the lifting platform 300 rises to the first position; and the guiding portion 310 is configured to move from the second horizontal section 2213 to the first horizontal section 2212 during the movement of the moving member 220, so that the lifting platform 300 descends to the second position.

[0055] It can be understood that it is sufficient that the extending directions of the first and second horizontal sections 2212 and 2213 are substantially the same as the moving direction of the moving member 220.

[0056] During the movement of the moving member 220, the guiding portion 310 moves from the first horizontal section 2212 through the inclined section 2211 to the second horizontal section 2213, and at this time, the lifting platform 300 rises to the first position; during the reverse movement of the moving member 220, the guiding portion 310 moves from the second horizontal section 2213 through the inclined section 2211 to the first horizontal section 2212, and at this time, the lifting platform 300 descends to the second position.

[0057] During the movement of the guiding portion 310 within the inclined section 2211, the lifting platform 300 can be raised or lowered. When the guiding portion 310 moves to the first horizontal section 2212, the lifting platform 300 can be relatively stably maintained at the second position. When the guiding portion 310 moves to the second horizontal section 2213, the lifting platform 300 can be relatively stably maintained at the first position.

[0058] In some embodiments, an elastic reset member 120 is provided on the mounting main body 100. The elastic reset member 120 is connected to the rotating member 210. The rotating member 210 is configured to rotate under the elastic action of the elastic reset member 120, thereby driving the movement of the moving member 220 to raise the lifting platform 300 to the first position.

[0059] The elastic reset member 120 is connected to the rotating member 210, so that the rotating member 210 has a tendency to rotate clockwise. The rotating member 210 can rotate clockwise under the elastic action of the elastic reset member 120, thereby driving the movement of the moving member 220 until the lifting platform 300 rises to the first position.

[0060] In an alternative embodiment, the elastic reset member 120 is a torsion spring. The torsion spring is sleeved on the first rotating pin 190. The two ends of the torsion spring are respectively connected to the mounting main body 100 and the rotating member 210. The rotating member 210 can rotate clockwise under the action of the torsion spring. In other embodiments, the elastic reset member 120 can also be other elastic members such as elastic sheets, and no limitation is made thereto.

[0061] Please refer to Figures 4 - 6 , in some embodiments, the rotating member 210 includes a connected cover plate 211 and a connecting arm 212. The connecting arm 212 is rotatably connected to the mounting main body 100. The cover plate 211 has an open state and a closed state during rotation. The cover plate 211 is in the open state when the lifting platform 300 is in the first position, and the cover plate 211 is in the closed state when the lifting platform 300 is in the second position. Among them, the cover plate 211 closes the accommodating cavity 110 in the closed state, and the cover plate 211 exposes the accommodating cavity 110 in the open state.

[0062] The cover plate 211 and the connecting arm 212 are fixedly connected. The connecting arm 212 is rotatably connected to the mounting body 100 through the first rotating pin 190. The cover plate 211 can rotate around the first rotating pin 190 along with the connecting arm 212.

[0063] The first rotating pin 190 is located at the connection between the connecting arm 212 and the mounting body 100. A second rotating pin 231 is provided at the connection between the connecting rod 230 and the connecting arm 212. The first rotating pin 190 and the second rotating pin 231 are not coaxial, so that the cover plate 211 can drive the moving member 220 to move during the rotation process.

[0064] When the lifting platform 300 is in the first position, the cover plate 211 is in the open state. At this time, the cover plate 211 is located on one side of the lifting platform 300 and does not block the lifting platform 300; when the lifting platform 300 is in the second position, the cover plate 211 is in the closed state. At this time, the cover plate 211 is located above the lifting platform 300 to block part or all of the lifting platform 300.

[0065] In some embodiments, a mating tooth portion 2121 is provided on the connecting arm 212, and a damper 130 is provided on the mounting body 100 that mates with the mating tooth portion 2121.

[0066] The outer edge of the connecting arm 212 is arc-shaped. The mating tooth portion 2121 includes a plurality of mating teeth continuously arranged along the outer edge of the connecting arm 212. During the rotation of the cover plate 211, due to the cooperation between the mating tooth portion 2121 and the damper 130, the rotation feel of the cover plate 211 is better.

[0067] In some embodiments, a first guiding portion is provided on the mounting body 100 for guiding the moving member 220 in the moving direction of the moving member 220; and / or, a second guiding portion is provided on the mounting body 100 for guiding the lifting platform 300 in the moving direction of the lifting platform 300.

[0068] The moving direction of the moving member 220 is perpendicular to the moving direction of the lifting platform 300. In the embodiments of the present application, the moving direction of the moving member 220 is the horizontal direction, and the moving direction of the lifting platform 300 is the vertical direction.

[0069] By providing the first guiding portion on the mounting body 100, the first guiding portion guides the moving member 220 in the horizontal direction, so that the moving member 220 can move stably in the horizontal direction; by providing the second guiding portion on the mounting body 100, the second guiding portion guides the lifting platform 300 in the vertical direction, so that the lifting platform 300 can move stably in the vertical direction.

[0070] In an alternative embodiment, both the first guiding portion and the second guiding portion are guiding grooves, and guiding blocks adapted to the corresponding guiding grooves can be provided on both the moving member 220 and the lifting platform 300, so as to guide the moving member 220 in the horizontal direction and guide the lifting platform 300 in the vertical direction.

[0071] It can be understood that in other embodiments, the first guiding portion and the second guiding portion may also be other guiding structures, as long as they can guide the moving member 220 in the horizontal direction and guide the lifting platform 300 in the vertical direction, and no limitation is imposed thereon.

[0072] It should be understood that by setting the inclination section 2211 and the angles of the first and second guiding portions, the moving direction of the moving member 220 and the moving direction of the lifting platform 300 can form an angle and are not completely perpendicular.

[0073] Please refer to Figures 7 - 11 , in some embodiments, a locking member 140 is rotatably provided on the mounting body 100. The locking member 140 has a locking position for locking the rotating member 210 and an unlocking position for unlocking the rotating member 210. Wherein, when the locking member 140 releases the locking of the lifting platform 300, the locking member 140 remains in the unlocking position to avoid the lifting platform 300 during the moving stroke of the lifting platform 300. The lifting mechanism 10 further includes an unlocking member 150. The unlocking member 150 is movably provided on the mounting body 100, and the unlocking member 150 is used to push the locking member 140 to rotate to the unlocking position during the movement.

[0074] When the cover plate 211 is in the closed state, the locking member 140 is in the locking position and locks the cover plate 211, so as to lock the lifting platform 300. The unlocking member 150 can push the locking member 140 to rotate to the unlocking position during the movement, so that the locking member 140 is unlocked from the cover plate 211, thereby unlocking the lifting platform 300. When the locking member 140 is unlocked from the cover plate 211, the cover plate 211 will rotate to the open state under the action of the elastic reset member 120, and the lifting platform 300 rises to the first position.

[0075] The unlocking member 150 may be selected as a button. When the button is pressed, the button can push the locking member 140 to rotate to the unlocking position.

[0076] The locking member 140 in the unlocking position can avoid the lifting platform 300 both when the lifting platform 300 descends from the first position to the second position and when it rises from the second position to the first position, so as not to easily affect the normal lifting of the lifting platform 300.

[0077] In some embodiments, a first elastic member 160 is disposed between the locking member 140 and the mounting body 100, and the first elastic member 160 is configured to bias the locking member 140 to rotate to the unlocked position.

[0078] By disposing the first elastic member 160 between the locking member 140 and the mounting body 100, when the locking member 140 is unlocked from the cover plate 211, the first elastic member 160 can cause the locking member 140 to rotate to the unlocked position and stably remain in the unlocked position, thus not easily affecting the normal lifting of the lifting platform 300.

[0079] In an alternative embodiment, the first elastic member 160 is a torsion spring, one end of the torsion spring is fixed to the locking member 140, and the other end of the torsion spring is fixed to the mounting body 100.

[0080] This torsion spring can bias the locking member 140 to rotate to the unlocked position. In other embodiments, the first elastic member 160 can also be other elastic members such as elastic sheets, which are not limited herein.

[0081] In some embodiments, the locking member 140 includes a locking tongue 141 and a clutch 142. The locking tongue 141 and the clutch 142 are both rotatably disposed on the mounting body 100, and the locking tongue 141 and the clutch 142 tend to maintain their relative positions (a tendency to maintain the angle therebetween unchanged); the lifting platform 300 is configured to push the clutch 142 to rotate during the process of moving from the first position to the second position, so that the locking tongue 141 rotates from the unlocked position to the locked position.

[0082] The locking tongue 141 has a locked position and an unlocked position. During the process of the lifting platform 300 descending from the first position to the second position, the locking tongue 141 can be pushed to rotate by the clutch 142. Since the locking tongue 141 and the clutch 142 tend to maintain their relative positions, the locking tongue 141 will rotate in the same direction as the clutch 142 from the unlocked position to the locked position and lock to the cover plate 211.

[0083] When the unlocking member 150 pushes the locking tongue 141 to rotate to the unlocked position, the cover plate 211 rotates from the closed state to the open state, and the lifting platform 300 rises from the second position to the first position. Since the locking tongue 141 and the clutch 142 tend to maintain their relative positions, the clutch 142 will rotate towards the locking tongue 141 in the unlocked position.

[0084] The locking tongue 141 in the unlocked position can avoid the lifting platform 300 during both the process of the lifting platform 300 descending from the first position to the second position and the process of rising from the second position to the first position, thus not easily affecting the normal lifting of the lifting platform 300.

[0085] When the first elastic member 160 is a torsion spring, the torsion spring is sleeved on the clutch 142. One end of the torsion spring is fixed to the clutch 142, and the other end of the torsion spring is fixed to the mounting body 100. Optionally, two such torsion springs can be symmetrically arranged along the rotation axis direction of the clutch 142.

[0086] In some embodiments, a second elastic member 143 is provided between the locking tongue 141 and the clutch 142. The locking tongue 141 is provided with a first abutting surface 1411, and the clutch 142 has a second abutting surface 1421. The second elastic member 143 causes the locking tongue 141 and the clutch 142 to have a tendency to rotate towards each other. Cooperating with the abutment of the first abutting surface 1411 and the second abutting surface 1421, the locking tongue 141 and the clutch 142 have a tendency to maintain their relative included angle, so as to limit the relative position of the locking tongue 141 and the clutch 142.

[0087] The locking tongue 141 and the clutch 142 each have an unlocking position and a locking position. When the locking tongue 141 is in the unlocking position, the clutch 142 has a tendency to rotate towards the unlocking position under the action of the second elastic member 143; when the clutch 142 is in the locking position, the locking tongue 141 has a tendency to rotate towards the locking position under the action of the second elastic member 143.

[0088] The clutch 142 includes a mating portion 1422. A groove 1423 is formed on the mating portion 1422. The locking tongue 141 includes a connecting portion 1412 and a locking portion 1413 connected to the connecting portion 1412. The connecting portion 1412 is located in the groove 1423; the first abutting surface 1411 is provided on the connecting portion 1412, and the second abutting surface 1421 is provided on the inner wall of the groove 1423. The first abutting surface 1411 and the second abutting surface 1421 are arranged facing each other.

[0089] The cover plate 211 is provided with a locking and mating portion. The locking and mating portion can be selected as a locking hole 2111. The locking portion 1413 is locked to the locking and mating portion to realize the locking of the cover plate 211 and the lifting platform 300.

[0090] In some embodiments, the clutch 142 is provided with a first abutting portion 1424, and the lifting platform 300 is provided with a second abutting portion 320. The second abutting portion 320 is used to push the first abutting portion 1424 during the process of the lifting platform 300 moving from the first position to the second position, so as to make the clutch 142 rotate.

[0091] The first abutting portion 1424 is connected to the mating portion 1422. The first abutting portion 1424 extends towards the side of the lifting platform 300. The second abutting portion 320 can be selected as an abutting post and is arranged at the bottom of the lifting platform 300. During the process of the lifting platform 300 descending from the first position to the second position, the second abutting portion 320 can abut against and push the first abutting portion 1424, thereby causing the clutch 142 to rotate.

[0092] The second elastic member 143 is arranged between the locking tongue 141 and the clutch 142. When the unlocking member 150 pushes the locking tongue 141 to rotate to the unlocking position, the lifting platform 300 rises, and the clutch 142 rotates towards the unlocking position under the action of the second elastic member 143 until the first abutting surface 1411 and the second abutting surface 1421 abut against each other.

[0093] When the second abutting portion 320 pushes the first abutting portion 1424 to cause the clutch 142 to rotate to the locking position, the locking tongue 141 rotates towards the locking position under the action of the second elastic member 143 until the locking portion 1413 of the locking tongue 141 locks onto the cover plate 211.

[0094] In an alternative embodiment, the second elastic member 143 is a torsion spring. A first pin 170 is arranged on the mounting body 100. The locking tongue 141 and the clutch 142 are both rotatably arranged on the first pin 170. The torsion spring is sleeved on the first pin 170, and the two ends of the torsion spring respectively abut against the locking tongue 141 and the clutch 142.

[0095] The connecting portion 1412 of the locking tongue 141 and the mating portion 1422 of the clutch 142 are both rotatably arranged on the first pin 170 of the mounting body 100. The two ends of the torsion spring are respectively fixed to the connecting portion 1412 of the locking tongue 141 and the first abutting portion 1424 of the clutch 142. This torsion spring can cause the locking tongue 141 and the clutch 142 to have a tendency to rotate towards each other. In other embodiments, the second elastic member 143 can also be other elastic members such as elastic sheets, and no limitation is made thereto.

[0096] The process of the unlocking member 150 rotating from the locking position to the unlocking position is shown in sequence according to Figures 12 - 15 First, use the unlocking member 150 to push the locking tongue 141 to rotate to the unlocking position. After the cover plate 211 is unlocked, it rotates from the closed state to the open state under the action of the elastic reset member 120. The lifting platform 300 rises from the second position to the first position. The second abutting portion 320 of the lifting platform 300 releases the abutment against the first abutting portion 1424 of the clutch 142. The clutch 142 rotates counterclockwise, and the first abutting portion 1424 of the clutch 142 gradually approaches the locking portion 1413 of the locking tongue 141 until the first abutting surface 1411 and the second abutting surface 1421 abut against each other.

[0097] The process of the unlocking member 150 rotating from the unlocking position to the locking position is shown in sequence according toFigure 15 , Figure 13 , Figure 12 They are shown in sequence. Press the cover plate 211 to rotate the cover plate 211 from the open state to the closed state. The lifting platform 300 descends from the first position to the second position. The second abutting portion 320 of the lifting platform 300 abuts against the first abutting portion 1424 of the clutch 142. The clutch 142 rotates clockwise. The locking tongue 141 rotates from the unlocking position to the locking position under the action of the second elastic member 143 until the locking portion 1413 of the locking tongue 141 cooperates with the locking hole 2111 on the cover plate 211 to lock the cover plate 211 again.

[0098] Please refer to Figure 16 , a linkage member 180 is rotatably provided on the mounting body 100. An abutting surface 181 is provided on the linkage member 180. The unlocking member 150 is used to push the linkage member 180 to rotate clockwise during the process of being pressed and moving, so that the linkage member 180 pushes the locking member 140 to rotate counterclockwise to the unlocking position through the abutting surface 181.

[0099] The unlocking member 150 is provided with an inclined groove 151. The linkage member 180 is provided with a mating pin 182 that cooperates with the inclined groove 151. One end of the linkage member 180 away from the mating pin 182 is provided with a rotating shaft, and the rotating shaft is rotatably connected to the mounting body 100; the abutting surface 181 is provided on one side of the linkage member 180 facing the locking tongue 141, and the locking tongue 141 is provided with a second shaft pin 1414 on the connecting portion 1412 for abutting against the abutting surface 181.

[0100] During the process of the unlocking member 150 being pressed and moving, the unlocking member 150 drives the linkage member 180 to rotate clockwise around the rotating shaft at one end of the linkage member 180 away from the mating pin 182 through the inclined groove 151. The linkage member 180 abuts against and pushes the second shaft pin 1414 on the connecting portion 1412 through the abutting surface 181, so that the locking tongue 141 rotates counterclockwise to the unlocking position.

[0101] The working principle of the lifting mechanism 10 provided by the embodiment of the present application is as follows: When an item needs to be placed, the unlocking member 150 is used to push the locking tongue 141 to rotate to the unlocking position. Under the action of the elastic reset member 120, the cover plate 211 rotates to the open state. The connecting arm 212 rotates following the cover plate 211 and drives the moving member 220 to move through the connecting rod 230. During the movement of the moving member 220, the lifting platform 300 is driven to rise to the first position through the cooperation of the guiding track 221 and the guiding portion 310, so as to place an item on the lifting platform 300. When there is no item placed on the lifting platform 300, the cover plate 211 can be rotated to the closed state. The connecting arm 212 rotates following the cover plate 211 and drives the moving member 220 to move in the reverse direction. During the movement of the moving member 220, the lifting platform 300 is driven to descend to the second position through the cooperation of the guiding track 221 and the guiding portion 310. During the descending process of the lifting platform 300, the clutch 142 is pushed to rotate, and the locking tongue 141 rotates to the locking position under the action of the second elastic member 143 to lock the cover plate 211.

[0102] Figure 17 The state in which the lifting mechanism 10 is applied to an automobile is shown, where the lifting mechanism 10 is disposed on the center console of the automobile.
