Description
Technical Field
[0001] This application relates to the field of vehicle-mounted equipment technology, and more specifically, to a lifting mechanism. Background Technology
[0002] With the continuous advancement of automotive electronics technology, modern car center consoles integrate more and more functional modules, such as navigation systems, entertainment systems, air conditioning control systems, and vehicle information display systems. The addition of these modules makes the interior space of the center console increasingly complex and compact. At the same time, in order to enhance the driving experience and the aesthetics of the vehicle interior, automakers often pursue a simple and integrated design for the center console, which further reduces the usable space inside.
[0003] Consumers generally need to place personal items such as water cups, mobile phones, and keys inside the center console, but due to the increasingly limited space inside the center console of current cars, it is not convenient to place items. Utility Model Content

Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0039] It should be noted that similar labels and letters in the following figures indicate similar items. 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 this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0042] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0043] Please refer to Figure 1 The embodiments of this application provide a lifting mechanism 10, including a mounting body 100, a movable component 200, and a lifting platform 300. The mounting body 100 has a receiving cavity 110. The movable component 200 is movably disposed on the mounting body 100 and cooperates with the lifting platform 300. The movable component 200 is used to drive the lifting platform 300 to rise to a first position or fall to a second position during the movement. When the lifting platform 300 is in the first position, it extends at least partially 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 body 100 is the main part of the car's center console. The internal cavity 110 of the mounting body 100 has insufficient space, which makes it inconvenient to place items. For example, when the lifting platform 300 is a cup holder structure, the cup holder structure is not deep enough in the cavity 110. In this case, raising the cup holder structure to outside the cavity 110 can utilize the space outside the cavity 110 to increase the depth of the cup holder structure so that cups can be placed.
[0045] The movable component 200 is movable relative to the mounting body 100. During the movement, the movable component 200 can drive the lifting platform 300 to rise to the first position or fall to the second position. The first position and the second position are the two extreme positions in the movement stroke of the lifting platform 300.
[0046] When items need to be placed, the movable part 200 moves relative to the mounting body 100, and the movable part 200 drives the lifting platform 300 to rise to the first position. At this time, the lifting platform 300 extends at least partially outside the receiving cavity 110, and items can be placed on the lifting platform 300, thereby utilizing the space outside the receiving cavity 110 and making it easier to place items. When there are no items placed on the lifting platform 300, the movable part 200 moves relative to the mounting body 100, and the movable part 200 drives the lifting platform 300 to fall to the second position. At this time, the lifting platform 300 is located inside the receiving cavity 110.
[0047] Please refer to Figure 2 , Figure 3In some embodiments, the movable component 200 includes a rotating component 210, a moving component 220, and a connecting rod 230 connecting the rotating component 210 and the moving component 220. The rotating component 210 is rotatably disposed on the mounting body 100, and the moving component 220 is movably disposed on the mounting body 100. The moving component 220 cooperates with the lifting platform 300. The rotating component 210 is used to drive the moving component 220 to move through the connecting rod 230 during rotation. The moving component 220 is used to drive the lifting platform 300 to rise to a first position or fall to a second position during movement.
[0048] The movable component 220 can be a plate. The mounting body 100 is provided with a first rotating pin 190. The rotating component 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 hinged to the rotating component 210 and the movable component 220 respectively.
[0049] During the upward stroke of the lifting platform 300, the rotating component 210 rotates along the first direction. During the rotation, the rotating component 210 drives the moving component 220 to move via the connecting rod 230. During the movement, the moving component 220 drives the lifting platform 300 to rise to the first position. During the downward stroke of the lifting platform 300, the rotating component 210 rotates along the second direction. During the rotation, the rotating component 210 drives the moving component 220 to move in the opposite direction via the connecting rod 230. During the movement, the moving component 220 drives the lifting platform 300 to fall to the second position. The first direction and the second direction are respectively one of the clockwise direction and the counterclockwise direction. In the embodiment of this application, the first direction is the clockwise direction and the second direction is the counterclockwise direction for illustration.
[0050] In some embodiments, a guide rail 221 is provided on one of the movable member 220 and the lifting platform 300. The extension direction of at least a portion of the guide rail 221 is set at an angle to the moving direction of the movable member 220. A guide portion 310 is provided on the other of the movable member 220 and the lifting platform 300 to cooperate with the guide rail 221. The guide portion 310 is used to move along the guide rail 221 during the movement of the movable member 220, so that the lifting platform 300 rises to a first position or falls to a second position.
[0051] The guide part 310 can be a guide shaft, which is adjacent to and cooperates with the guide rail 221. During the movement of the moving part 220, the guide part 310 moves along the guide rail 221, thereby driving the lifting platform 300 to rise to the first position or fall to the second position.
[0052] Optionally, the guide rail 221 is disposed on the moving part 220, and the guide part 310 is disposed on the lifting platform 300; or, the guide rail 221 is disposed on the lifting platform 300, and the guide part 310 is disposed on the moving part 220.
[0053] Optionally, the guide rail 221 can be in the form of a guide groove, which is formed in the moving part 220 or in the lifting platform 300. The guide shaft extends into the guide groove and cooperates with the guide groove. During the movement of the moving part 220, the guide part 310 moves in the guide groove, thereby driving the lifting platform 300 to rise to the first position or fall to the second position.
[0054] The guide rail 221 includes an inclined section 2211 and a first horizontal section 2212 and a second horizontal section 2213 connected to both ends of the inclined section 2211. The extension direction of the inclined section 2211 is set at an angle to the movement direction of the moving member 220. The extension directions of the first horizontal section 2212 and the second horizontal section 2213 are consistent with the movement direction of the moving member 220. The guide part 310 is used 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 guide part 310 is used 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 is understandable that the extension direction of the first horizontal segment 2212 and the second horizontal segment 2213 is roughly consistent with the movement direction of the moving part 220.
[0056] During the movement of the movable component 220, the guide section 310 moves from the first horizontal section 2212 through the inclined section 2211 to the second horizontal section 2213, at which time the lifting platform 300 rises to the first position; during the reverse movement of the movable component 220, the guide section 310 moves from the second horizontal section 2213 through the inclined section 2211 to the first horizontal section 2212, at which time the lifting platform 300 descends to the second position.
[0057] During the movement of the guide section 310 within the inclined section 2211, the lifting platform 300 can rise or fall. When the guide section 310 moves to the first horizontal section 2212, the lifting platform 300 can be kept relatively stably in the second position. When the guide section 310 moves to the second horizontal section 2213, the lifting platform 300 can be kept relatively stably in the first position.
[0058] In some embodiments, an elastic reset member 120 is provided on the mounting body 100. The elastic reset member 120 is connected to the rotating member 210. The rotating member 210 is used to rotate under the elastic action of the elastic reset member 120, thereby driving the moving member 220 to move, so that the lifting platform 300 rises 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 clockwise rotation tendency. The rotating member 210 can rotate clockwise under the elastic action of the elastic reset member 120, thereby driving the moving member 220 to move until the lifting platform 300 rises to the first position.
[0060] In an optional embodiment, the elastic reset member 120 is a torsion spring, which is sleeved on the first rotating pin 190. The two ends of the torsion spring are respectively connected to the mounting body 100 and the rotating member 210, and 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 a spring sheet, and there is no limitation on this.
[0061] Please refer to Figures 4-6 In some embodiments, the rotating member 210 includes a cover plate 211 and a connecting arm 212 connected to each other. The connecting arm 212 is rotatably connected to the mounting 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 in the closed state when the lifting platform 300 is in the second position. In the closed state, the cover plate 211 closes the receiving cavity 110, and in the open state, the cover plate 211 exposes the receiving cavity 110.
[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 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. The 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 on the same axis, so that the cover plate 211 can drive the moving part 220 to move during the rotation.
[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 will not obstruct 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 so as to obstruct part or all of the lifting platform 300.
[0065] In some embodiments, the connecting arm 212 is provided with a mating tooth 2121, and the mounting body 100 is provided with a damper 130 that mates with the mating tooth 2121.
[0066] The outer edge of the connecting arm 212 is arc-shaped, and the mating tooth 2121 includes multiple mating teeth continuously arranged along the outer edge of the connecting arm 212. During the rotation of the cover plate 211, the mating tooth 2121 and the damper 130 make the rotation feel of the cover plate 211 better.
[0067] In some embodiments, the mounting body 100 is provided with a first guide portion for guiding the moving member 220 in the moving direction of the moving member 220; and / or, the mounting body 100 is provided with a second guide portion for guiding the lifting platform 300 in the moving direction of the lifting platform 300.
[0068] The moving direction of the movable component 220 is perpendicular to the moving direction of the lifting platform 300. In the embodiments of this application, the moving direction of the movable component 220 is horizontal, and the moving direction of the lifting platform 300 is vertical.
[0069] By providing a first guide part on the mounting body 100, the first guide part guides the moving part 220 in the horizontal direction, enabling the moving part 220 to move stably in the horizontal direction; by providing a second guide part on the mounting body 100, the second guide part guides the lifting platform 300 in the vertical direction, enabling the lifting platform 300 to move stably in the vertical direction.
[0070] In an optional embodiment, both the first guide portion and the second guide portion are guide grooves, and guide blocks that cooperate with the corresponding guide grooves can be provided on both the moving part 220 and the lifting platform 300, thereby realizing the horizontal guidance of the moving part 220 and the vertical guidance of the lifting platform 300.
[0071] It is understood that in other embodiments, the first guide portion and the second guide portion may be other guide structures, as long as they can guide the moving part 220 in the horizontal direction and guide the lifting platform 300 in the vertical direction, and there is no limitation on this.
[0072] It should be understood that by setting the angles of the inclined section 2211 and the first and second guide sections, the moving direction of the moving member 220 can be at an angle to the moving direction of the lifting platform 300, rather than being completely perpendicular.
[0073] Please refer to Figures 7-11In some embodiments, a locking member 140 is rotatably disposed 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. The locking member 140 in the unlocking position is used to avoid the lifting platform 300 during its travel. The lifting mechanism 10 also includes an unlocking member 150, which is movably disposed on the mounting body 100. The unlocking member 150 is used to push the locking member 140 to the unlocking position during movement.
[0074] When the cover plate 211 is in the closed state, the locking member 140 is in the locked position and locked to the cover plate 211, thereby locking the lifting platform 300; the unlocking member 150 can push the locking member 140 to the unlock position during the movement, so that the locking member 140 and the cover plate 211 are unlocked, thereby unlocking the lifting platform 300. When the locking member 140 and the cover plate 211 are unlocked, the cover plate 211 will rotate to the open state under the action of the elastic reset member 120, and the lifting platform 300 will rise to the first position.
[0075] The unlocking element 150 can be a button, which, when pressed, can push the locking element 140 to the unlock position.
[0076] The locking component 140, when in the unlocked position, can avoid the lifting platform 300 during the process of the lifting platform 300 descending from the first position to the second position and rising from the second position to the first position, thus making it less likely to affect the normal lifting and lowering of the lifting platform 300.
[0077] In some embodiments, a first elastic member 160 is provided between the locking member 140 and the mounting body 100, the first elastic member 160 being used to give the locking member 140 a tendency to rotate to the unlocked position.
[0078] By providing a first elastic element 160 between the locking element 140 and the mounting body 100, when the locking element 140 is unlocked from the cover plate 211, the first elastic element 160 can rotate the locking element 140 to the unlocked position and stably maintain it in the unlocked position, thus not easily affecting the normal lifting and lowering of the lifting platform 300.
[0079] In an optional embodiment, the first elastic element 160 is a torsion spring, one end of which is fixed to the locking element 140, and the other end of which is fixed to the mounting body 100.
[0080] The torsion spring can cause the locking member 140 to have a tendency to rotate to the unlocked position. In other embodiments, the first elastic member 160 can also be other elastic members such as a spring sheet, and there is no limitation on this.
[0081] In some embodiments, the locking member 140 includes a locking tongue 141 and a clutch 142, both of which are rotatably disposed on the mounting body 100. The locking tongue 141 and the clutch 142 have a tendency to rotate in opposite directions (when the clutch 142 is stationary, the locking tongue 141 has a tendency to rotate clockwise toward the locking position, and when the locking tongue 141 is stationary, the clutch 142 has a tendency to rotate counterclockwise toward the unlocking position). The lifting platform 300 is used 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 unlocking position to the locking position.
[0082] The locking tongue 141 has a locking position and an unlocking position. During the process of the lifting platform 300 descending from the first position to the second position, it can push the clutch 142 to rotate. Since the locking tongue 141 and the clutch 142 have a tendency to rotate in opposite directions, the locking tongue 141 will rotate from the unlocking position to the locking position and lock to the cover plate 211.
[0083] When the unlocking component 150 pushes the locking tongue 141 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 have a tendency to rotate in opposite directions, the clutch 142 will rotate toward the locking tongue 141 in the unlocked position.
[0084] When the locking tongue 141 is in the unlocked position, it can avoid the lifting platform 300 during the process of the lifting platform 300 descending from the first position to the second position and rising from the second position to the first position, so as not to affect the normal lifting and lowering of the lifting platform 300.
[0085] When the first elastic element 160 is a torsion spring, the torsion spring is sleeved on the clutch 142, with one end of the torsion spring fixed to the clutch 142 and the other end fixed to the mounting body 100. Optionally, two torsion springs may be symmetrically arranged along the rotation axis of the clutch 142.
[0086] In some embodiments, the latch 141 is provided with a first stop surface 1411, and the clutch 142 is provided with a second stop surface 1421. The first stop surface 1411 and the second stop surface 1421 are used to abut against each other during the process of the latch 141 and the clutch 142 rotating towards each other, so that the latch 141 and the clutch 142 remain in a relatively fixed state.
[0087] The clutch 142 includes a mating part 1422, on which a groove 1423 is provided. The locking tongue 141 includes a connecting part 1412 and a locking part 1413 connected to the connecting part 1412. The connecting part 1412 is located in the groove 1423. A first stop surface 1411 is provided on the connecting part 1412, and a second stop surface 1421 is provided on the inner wall of the groove 1423. The first stop surface 1411 and the second stop surface 1421 are arranged facing each other.
[0088] The cover plate 211 is provided with a locking engagement part, which can be selected as a lock hole 2111. The locking part 1413 is locked to the locking engagement part to realize the locking of the cover plate 211 and the lifting platform 300.
[0089] In some embodiments, the clutch 142 is provided with a first abutment portion 1424, and the lifting platform 300 is provided with a second abutment portion 320. The second abutment portion 320 is used to push the first abutment 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 clockwise.
[0090] The first abutment 1424 is connected to the mating part 1422. The first abutment 1424 extends toward one side of the lifting platform 300. The second abutment 320 can be an abutment column and is disposed 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 abutment 320 can abut against and push the first abutment 1424, thereby causing the clutch 142 to rotate clockwise.
[0091] In some embodiments, a second elastic element 143 is provided between the locking tongue 141 and the clutch 142, the second elastic element 143 being used to give the locking tongue 141 and the clutch 142 a tendency to rotate in opposite directions.
[0092] The second elastic element 143 is disposed between the locking tongue 141 and the clutch 142. When the unlocking element 150 pushes the locking tongue 141 to the unlocking position, the lifting platform 300 rises, and the clutch 142 rotates counterclockwise under the action of the second elastic element 143 until the first stop surface 1411 and the second stop surface 1421 abut against each other.
[0093] When the second abutment 320 pushes the first abutment 1424 to make the clutch 142 rotate clockwise, the locking tongue 141 also rotates clockwise under the action of the second elastic member 143 until the locking part 1413 of the locking tongue 141 is locked to the cover plate 211.
[0094] In an optional embodiment, the second elastic element 143 is a torsion spring, and a first shaft pin 170 is provided on the mounting body 100. The locking tongue 141 and the clutch 142 are rotatably disposed on the first shaft pin 170. The torsion spring is sleeved on the first shaft pin 170, and the two ends of the torsion spring are fixed to the locking tongue 141 and the clutch 142 respectively.
[0095] The connecting portion 1412 of the locking tongue 141 and the mating portion 1422 of the clutch 142 are rotatably mounted on the first shaft 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. The torsion spring can make the locking tongue 141 and the clutch 142 have a tendency to rotate in opposite directions. In other embodiments, the second elastic element 143 can also be a spring sheet or other elastic elements, which is not limited.
[0096] The process of the unlocking component 150 rotating from the locked position to the unlocked position is as follows: Figures 12-15 The sequence is shown in sequence. First, the unlocking member 150 pushes the locking tongue 141 to the unlocked 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 part 320 of the lifting platform 300 releases its abutment on the first abutting part 1424 of the clutch 142. The clutch 142 rotates counterclockwise. The first abutting part 1424 of the clutch 142 gradually approaches the locking part 1413 of the locking tongue 141 until the first stop surface 1411 and the second stop surface 1421 abut against each other.
[0097] The process of the unlocking component 150 rotating from the unlocked position to the locked position is as follows: Figure 15 , Figure 13 , Figure 12 The sequence is shown in turn: Press the cover plate 211 to rotate it from the open state to the closed state. The lifting platform 300 descends from the first position to the second position. The second abutting part 320 of the lifting platform 300 abuts against the first abutting part 1424 of the clutch 142. The clutch 142 rotates clockwise. Under the action of the second elastic member 143, the locking tongue 141 rotates from the unlocked position to the locked position until the locking part 1413 of the locking tongue 141 engages with the locking hole 2111 on the cover plate 211, thereby locking the cover plate 211 again.
[0098] Please refer to Figure 16 The mounting body 100 is rotatably provided with a linkage 180, and the linkage 180 is provided with an abutment surface 181. The unlocking member 150 is used to push the linkage 180 to rotate clockwise during the process of being pressed and moving, so that the linkage 180 pushes the locking member 140 to rotate counterclockwise to the unlock position through the abutment surface 181.
[0099] The unlocking component 150 is provided with a slanted groove 151, and the linkage component 180 is provided with a mating pin 182 that mates with the slanted groove 151. The end of the linkage component 180 away from the mating pin 182 is provided with a rotating shaft, which is rotatably connected to the mounting body 100. The abutment surface 181 is provided on the side of the linkage component 180 facing the locking tongue 141, and the locking tongue 141 is provided with a second shaft pin 1414 on the connecting part 1412 for abutting against the abutment 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 rotation axis of the 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 part 1412 through the abutment surface 181, so that the locking tongue 141 rotates counterclockwise to the unlock position.
[0101] The working principle of the lifting mechanism 10 provided in this embodiment is as follows: When it is necessary to place an item, the unlocking member 150 pushes the locking tongue 141 to rotate to the unlocked position. Under the action of the elastic reset member 120, the cover plate 211 rotates to the open state. The connecting arm 212 rotates with the cover plate 211 and drives the moving member 220 to move through the connecting rod 230. During the movement, the moving member 220 drives the lifting platform 300 to rise to the first position through the cooperation of the guide rail 221 and the guide part 310, so that items can be placed on the lifting platform 300. When there are no items placed on the lifting platform 300, the cover plate 211 can be rotated to the closed state. The connecting arm 212 rotates with the cover plate 211 and drives the moving part 220 to move in the opposite direction through the connecting rod 230. During the movement, the moving part 220 drives the lifting platform 300 to the second position through the cooperation of the guide rail 221 and the guide part 310. During the descent, the lifting platform 300 pushes the clutch 142 to rotate. The locking tongue 141 rotates to the locking position under the action of the second elastic member 143 and locks the cover plate 211.
[0102] Figure 17 The image shows the state in which the lifting mechanism 10 is applied to a car, wherein the lifting mechanism 10 is located on the center console of the car.
[0103] In summary, this application provides a lifting mechanism 10, including a mounting body 100, a movable component 200, a locking component 140, an unlocking component 150, and a lifting platform 300. On the one hand, the unlocking component 150 can be used to push the locking component 140 to the unlocked position, and the movable component 200 can drive the lifting platform 300 to rise to the first position for placing items. On the other hand, the locking component 140 in the unlocked position can avoid the lifting platform 300 during the rising or falling of the lifting platform 300, and is less likely to affect the normal rising and falling of the lifting platform 300.
