DETAILED DESCRIPTION

[0109] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0110] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0111] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0112] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0113] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0114] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0115] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0116] A locking mechanism provided in this embodiment can be used in any linear movement adjustment device. During the movement along a straight line, it can stop and automatically lock at any position within the travel range to achieve stepless adjustment of the movement position. For example, it can be used in scenes such as lateral movement or vertical movement. In this embodiment, the locking mechanism is used on the cup holder device of the vehicle interior, which can achieve stepless lifting and lowering adjustment of the cup holder to adapt to cups of different heights, meet the usage needs of different users, and improve the user experience comfort.

[0117] The following takes the locking mechanism used to achieve stepless lifting and lowering adjustment of the cup holder as an example for detailed description.

[0118] Combination Figures 1 to 3 The locking mechanism includes a locking structure 10 and an unlocking structure 20. The locking structure 10 is used to achieve stopping and locking at any position during the movement. The unlocking structure 20 is used to achieve reverse movement and return to the initial position. Figure 2 This is a schematic diagram of the state in which the lifting cup holder is in the initial position (upper limit position) in this embodiment; Figure 3 This is a schematic diagram of the state in which the lifting cup holder in this embodiment is in a hovering state after being lowered to a certain height.

[0119] Combination Figures 4 to 5 The locking structure 10 includes a fixed base, a mounting base 310, a clamping body 320 and a pressing assembly 330. The clamping body 320 is disposed in the mounting base 310, and the pressing assembly 330 abuts against the clamping body 320. The mounting base 310 is movably disposed on the fixed base. The mounting base 310 moves under the action of the first external force, and the pressing assembly 330 pushes the clamping body 320 to move in the mounting base 310 while maintaining the abutment against the clamping body 320, so that the clamping body 320 abuts the mounting base 310 on the fixed base and locks the mounting base 310 at the current position. The locking mechanism can realize that the mounting base 310 stops and locks at any position within the moving stroke range, and realizes the stepless adjustment of the position of the mounting base 310. If the cup holder body is fixed on the mounting base 310, the stepless lifting and lowering adjustment of the cup holder body can be realized.

[0120] Optionally, a cavity for mounting the clamping body 320 is provided in the mounting base 310, and the cross section of the cavity changes gradually. During the movement of the mounting base 310, the clamping body 320 can move in the cavity under the abutment of the pressing assembly 330, and the pressing assembly 330 can finally enable the clamping body 320 to abut the mounting base 310 against the fixed base, thereby abutting and fixing the mounting base 310, and ensuring that the mounting base 310 stays reliably at the current position.

[0121] Combination Figure 6 and Figure 7 Optionally, the fixed base includes a guide rail column 500. The mounting base 310 is movably sleeved on the guide rail column 500, and a cavity for mounting the clamping body 320 is formed between the mounting base 310 and the guide rail column 500. That is, the clamping body 320 is disposed between the guide rail column 500 and the mounting base 310. The gap between the inner surface of the mounting base 310 and the outer surface of the guide rail column 500 gradually changes in the axial direction of the guide rail column 500. In this way, during the movement of the mounting base 310, due to the change in the gap, the clamping body 320 can move in the cavity under the action of the pressing assembly 330 until the clamping body 320 abuts against the mounting base 310 and the guide rail column 500 respectively, so as to achieve the fixing and locking of the mounting base 310.

[0122] Combination Figure 8, optionally, the cross-section of the guide rail column 500 gradually changes in the axial direction. In the present embodiment, the guide rail column 500 includes a first end face 510 and a second end face 520 that are arranged opposite to each other. In the direction from the first end face 510 to the second end face 520, the cross-sectional area of ​​the guide rail column 500 gradually decreases. That is, the guide rail column 500 presents an inverted cone surface with a gradually changing cross-section. During the movement of the mounting base 310 from the first end face 510 to the second end face 520, the gap between the mounting base 310 and the guide rail column 500 gradually increases.

[0123] In this embodiment, the cross section of the guide rail post 500 is circular. In other embodiments, the cross section of the guide rail post 500 may also be oval, square, rectangular, triangular, diamond or any other shape, which is not specifically limited here.

[0124] For the convenience of the following description, the direction from the first end surface 510 to the second end surface 520 is defined as downward, and the direction from the second end surface 520 to the first end surface 510 is defined as upward.

[0125] Combination Fig. 9 and Fig.10 Optionally, the clamping body 320 includes a guide rail clamping seat 321 and a rolling body 322. The guide rail clamping seat 321 is movably sleeved on the guide rail column 500, and the pressing assembly 330 abuts against the guide rail clamping seat 321. The rolling body 322 is rotatably mounted on the guide rail clamping seat 321. In the locked state, the rolling body 322 abuts against the inner surface of the mounting base 310 and the outer surface of the guide rail column 500 respectively.

[0126] Optionally, the guide rail clamping seat 321 is provided with a mounting groove 323, and the rolling body 322 is rotatably mounted in the mounting groove 323. It should be understood that the diameter of the rolling body 322 should be greater than the thickness of the guide rail clamping seat 321, that is, the rolling body 322 protrudes from the inner surface and the outer surface of the guide rail clamping seat 321, so that the rolling body 322 can contact the guide rail column 500 and the mounting base 310 respectively.

[0127] The rolling body 322 can be a metal ball, such as a steel ball, etc. The rolling body 322 can make the guide rail clamping seat 321 move along the guide rail column 500 more smoothly, and can also improve the wear resistance, slow down the wear of the guide rail clamping seat 321, the mounting base 310 and the guide rail column 500, extend the service life, and improve the reliability of the abutment.

[0128] Optionally, the clamping body 320 includes a plurality of rolling bodies 322, and the plurality of rolling bodies 322 are evenly distributed along the circumference of the guide rail column 500. In this embodiment, three rolling bodies 322 are provided. Of course, in some other embodiments, the number of rolling bodies 322 can be two, four, five, six or more. The plurality of rolling bodies 322 are evenly spaced, so that the force is more evenly applied and the movement is smoother.

[0129] Optionally, the guide rail clamping seat 321 is provided with a butting portion 324, and the pressing assembly 330 is in contact with the butting portion 324. The butting portion 324 is provided on the upper end surface 422 of the guide rail clamping seat 321 and is convex toward the outer surface of the guide rail clamping seat 321. In this way, the effective contact area between the pressing assembly 330 and the guide rail clamping seat 321 can be increased, ensuring that the pressing assembly 330 can be butted against the guide rail clamping seat 321, thereby improving the reliability of the butting.

[0130] In this embodiment, the portion of the mounting base 310 sleeved on the guide rail column 500 is roughly truncated cone-shaped. The guide rail clamping seat 321 is roughly truncated cone-shaped. This can better adapt to the guide rail column 500, thereby improving the reliability of locking.

[0131] Optionally, the mounting base 310 includes a third end face 311 and a fourth end face 312 that are arranged opposite to each other; the area of ​​the third end face 311 is larger than the area of ​​the fourth end face 312; the third end face 311 is arranged close to the first end face 510, and the fourth end face 312 is arranged close to the second end face 520.

[0132] like Figure 7 , the mounting base 310 moves downward along the guide rail column 500 under the first external force, and the gap between the mounting base 310 and the guide rail column 500 increases. The guide rail clamping seat 321 moves downward under the support of the pressing assembly 330, driving the rolling body 322 to move downward in the axial direction until the rolling body 322 abuts against the guide rail column 500 and the mounting base 310 respectively, and the guide rail clamping seat 321 stops moving downward. When the first external force is removed, since the rolling body 322 contacts the guide rail column 500 and the mounting base 310 respectively, and the guide rail column 500 has a gradually changing inverted cone surface, and the pressing assembly 330 abuts, the rolling body 322 will not move up and down, so that the mounting base 310 stays at the current position.

[0133] Combination Fig.11 Optionally, the pressing assembly 330 includes a first elastic member 350 and a pressing block 340 connected to each other, and the pressing block 340 is used to maintain the abutment against the clamping body 320 under the action of the first elastic member 350. The shape and structure of the pressing block 340 are not limited, as long as it can achieve the abutment against the guide rail clamping seat 321.

[0134] Optionally, the pressing block 340 includes a rotating shaft 341 and a first cam 342 disposed on the rotating shaft 341 , and the rotating shaft 341 is disposed on the mounting base 310 . The first elastic member 350 is connected to the first cam 342 , and the first cam 342 is used to abut against the clamping body 320 .

[0135] It should be noted that in some other embodiments, the pressing block 340 is not necessarily mounted on the mounting base 310, but may also be fixed on other brackets or carriers, such as a fixed base, which is not specifically limited here. When the gap between the mounting base 310 and the guide rail column 500 becomes larger, the pressing block 340 may approach the clamping body 320 by cam rotation or linear movement, so as to continuously push the clamping body 320 to move in the mounting base 310.

[0136] In this embodiment, the rotating shaft 341 is rotatably mounted on the mounting base 310. The first elastic member 350 is a torsion spring, which is sleeved on the rotating shaft 341. One end of the torsion spring is connected to the first cam 342, and the other end is in contact with the mounting base 310. Figure 7 The torsion spring always applies an elastic force to the first cam 342, so that the first cam 342 tends to rotate counterclockwise. When the gap between the mounting base 310 and the guide rail column 500 becomes larger, the first cam 342 rotates counterclockwise under the action of the torsion spring to continuously push the clamping body 320 to move in the mounting base 310 and keep the first cam 342 and the guide rail clamping seat 321 in contact.

[0137] Optional, combined Figure 5 A slot 313 is provided on the mounting base 310; one end of the torsion spring away from the first cam 342 is provided in the slot 313. The torsion spring is supported in the slot 313 to limit the position of the torsion spring.

[0138] Optionally, two lugs 314 are provided on the mounting base 310, and the two ends of the rotating shaft 341 are rotatably connected to the two lugs 314 respectively. The mounting base 310 is also provided with a partition 315 located between the two lugs 314. The partition 315 is provided with an avoidance hole 316 for the rotating shaft 341 to pass through; the partition 315 limits the axial position of the torsion spring. That is, the torsion spring and the first cam 342 are located between the partition 315 and one of the lugs 314. The avoidance hole 316 of the partition 315 also limits the rotating shaft 341 to a certain extent, ensuring that the rotating shaft 341 can only rotate around its own axis and will not move in the direction perpendicular to the axis.

[0139] It should be noted that, in some other embodiments, the rotating shaft 341 may be fixedly connected to the mounting base 310, and the first cam 342 may be rotatably disposed on the rotating shaft 341. Under the action of the torsion spring, the first cam 342 may also be rotated, thereby continuously pressing the guide rail clamping seat 321.

[0140] Optionally, a second cam 343 is provided on the rotating shaft 341, and the second cam 343 is used to drive the rotating shaft 341 to rotate under the action of the second external force, so that the first cam 342 moves in a direction relatively away from the clamping body 320. That is, the second cam 343 is used to cooperate with the unlocking structure 20 to drive the first cam 342 to rotate clockwise to reduce or cancel the holding force on the guide rail clamping seat 321, thereby realizing the reverse movement of the mounting base 310 or returning to the initial position.

[0141] In this embodiment, the first cam 342, the second cam 343 and the rotating shaft 341 are fixedly connected as a whole, and when one part of them rotates, the whole rotates together.

[0142] Optionally, the locking structure 10 further includes a second elastic member 360, which is disposed between the mounting base 310 and the clamping body 320 along the moving direction of the mounting base 310. The pressing assembly 330 is pressed against an end of the clamping body 320 away from the second elastic member 360. The second elastic member 360 is a compression spring, which is located between the guide rail clamping seat 321 and the bottom of the mounting base 310. The second elastic member 360 plays a role in buffering and helping the clamping body 320 to reset.

[0143] The unlocking structure 20 will be described below.

[0144] Combination Fig.12 and Fig.13 The unlocking structure 20 cooperates with the pressing assembly 330 to move the pressing assembly 330 in a direction relatively away from the clamping body 320. The unlocking structure 20 mainly cooperates with the second cam 343 in the pressing assembly 330 to achieve unlocking.

[0145] Combination Fig.14 and Fig.15 Optionally, the unlocking structure 20 includes an unlocking rod 410 and a push plate 420 connected to each other; the unlocking rod 410 moves under the action of the third external force, driving the push plate 420 to move, so that the push plate 420 and the holding assembly 330 abut against each other, thereby driving the holding assembly 330 to move in a direction away from the clamping body 320. For example, the unlocking rod 410 moves along the axial direction of the unlocking rod 410 under the action of the third external force, so that the push plate 420 moves in a direction perpendicular to the axial direction of the unlocking rod 410.

[0146] Optionally, an axial limit plate 421 is further included, and the axial limit plate 421 is used to prevent the push plate 420 from moving axially along the unlocking rod 410. One end of the push plate 420 is rotatably connected to the unlocking rod 410, and the other end of the push plate 420 is movably arranged on the axial limit plate 421. In this way, when the unlocking rod 410 moves axially, the push plate 420 can rotate around the unlocking rod 410, thereby converting into movement in the horizontal direction, so as to apply a force to the second cam 343, driving the second cam 343 to rotate clockwise. Among them, the axial limit plate 421 can be fixed on the cup holder body or on other carriers, which is not specifically limited here.

[0147] In this embodiment, both ends of the push plate 420 are rotatably connected to the unlocking rod 410. One end of the push plate 420 is limited by the axial limit plate 421. In this way, when the unlocking rod 410 moves in the axial direction, the push plate 420 can achieve a translational motion perpendicular to the axial direction of the unlocking rod 410, thereby applying a force to the second cam 343.

[0148] Optionally, the unlocking structure 20 further includes a connecting rod 450, and the two ends of the push plate 420 are respectively rotatably connected with the connecting rod 450, and the end of the connecting rod 450 away from the push plate 420 is rotatably connected to the unlocking rod 410. In this way, the push plate 420 can be smoothly moved, and the structure is more reliable. Optionally, each end of the push plate 420 is respectively connected to two connecting rods 450, and the two connecting rods 450 at the same end are respectively arranged on both sides of the push plate 420. That is, the unlocking structure 20 adopts a planar four-link 450 structure, which is conducive to improving the stability and reliability of the structure.

[0149] Optionally, the unlocking structure 20 further includes a third elastic member 460, one end of which is connected to the unlocking rod 410, and the other end of which is connected to the push plate 420. When the third external force on the unlocking rod 410 disappears, the push plate 420 returns to the initial state under the action of the third elastic member 460, that is, the push plate 420 is separated from the second cam 343. The third elastic member 460 is a spring. Of course, in some other embodiments, the third elastic member 460 may also be a spring or other elastic member, which is not specifically limited here.

[0150] In this embodiment, the unlocking structure 20 further includes a locking rod washer 440 and a buffer washer 430. The locking rod washer 440 is sleeved on the unlocking rod 410 to improve wear resistance and structural stability. The buffer washer 430 is sleeved on the end of the unlocking rod 410. The buffer washer 430 is used to connect with the button on the cup holder body to transmit the pressure of the button to the unlocking rod 410 to improve the reliability of button pressing.

[0151] Optionally, a limiting groove 411 is provided on the unlocking rod 410, and the push plate 420 is provided in the limiting groove 411, and the limiting groove 411 cooperates with the upper end surface 422 of the push plate 420. The upper groove wall of the limiting groove 411 can move axially relative to the upper end surface 422 of the push plate 420. The upper end surface 422 of the push plate 420 is used to limit the displacement of the unlocking rod 410 in the axial direction.

[0152] Optionally, the lower end surface 423 of the push plate 420 is in contact with the axial limiting plate 421 .

[0153] Combination Figure 1 , Figures 16 to 18 The embodiment of the present invention further provides a lifting cup holder, comprising a cup holder body and the aforementioned locking mechanism; the locking mechanism is mounted on the cup holder body.

[0154] Optionally, the cup holder body includes a bracket 100, a base 300 and a cup barrel 230. The bracket 100 is connected to the cup barrel 230, and the base 300 is used to support the cup body. The mounting base 310 is connected to the base 300, and the mounting base 310 and the base 300 can move along the axial direction of the cup barrel 230. The cup barrel 230 serves as a fixed base. The mounting base 310 includes a first section 317 disposed in the inner cavity of the cup barrel 230 and a second section 318 extending outside the inner cavity of the cup barrel 230. The first section 317 is connected to the base 300, a clamping body 320 is disposed in the second section 318, and a pressing assembly 330 is disposed in the second section 318.

[0155] Optionally, the cup barrel 230 includes a barrel body 231 and a bottom cover 232 connected to each other. The guide rail column 500 is fixedly mounted on the barrel body 231. A fourth elastic member 220 is disposed in the barrel body 231, one end of the fourth elastic member 220 is connected to the bottom cover 232, and the other end is abutted against the first section 317. When the first external force acting on the mounting base 310 disappears, and the unlocking structure 20 separates the pressing assembly 330 and the clamping body 320, the mounting base 310 and the bottom support 300 will return to the top of the cup barrel 230, i.e., the initial position, under the action of the fourth elastic member 220. The fourth elastic member 220 adopts a tower-shaped compression spring. Of course, in some other embodiments, the fourth elastic member 220 may also adopt a spring sheet or other elastic member.

[0156] Optionally, a track 200 is provided on the cup barrel 230, and the mounting base 310 is movably mounted on the track 200. The mounting base 310 moves along the track 200 during the lifting process, which can ensure that the mounting base 310 moves in a straight line and moves more smoothly. Optionally, a damper 210 is provided on the track 200. The damper 210 plays a buffering role to prevent the mounting base 310 from being impacted during the return process due to excessive restoring force of the fourth elastic member 220. In this embodiment, two tracks 200 and two dampers 210 are respectively provided, and one damper 210 is configured on each track 200, which can improve the stability of lifting.

[0157] Combination Fig.19 and Fig. 20 Optionally, an unlock button 400 is provided on the bracket 100. The unlock button 400 is connected to the unlock rod 410. In this embodiment, the unlock button 400 is connected to the buffer washer 430, which is used to apply an axial thrust to the unlock rod 410. The unlock button 400 is provided on the bracket 100 to facilitate the unlocking operation of the user.

[0158] Optionally, an axial limiting plate 421 for limiting the axial displacement of the push plate 420 is provided on the cup barrel 230 .

[0159] Combination Fig.24 and Fig.29 Optionally, the cup barrel 230 is provided with a first stopper 233 and a second stopper 234. The mounting base 310 moves from bottom to top along the cup barrel 230 to the first limit position, and the mounting base 310 abuts against the first stopper 233. The mounting base 310 moves from top to bottom along the cup barrel 230 to the second limit position, and the mounting base 310 abuts against the second stopper 234. In this embodiment, the first stopper 233 is provided at the upper edge of the cup barrel 230, so that when the mounting base 310 returns to the initial position after being unlocked, the second subdivision 318 of the mounting base 310 abuts against the first stopper 233 to limit the axial displacement during the ascending process. The second stopper 234 is provided on the bottom cover 232, and when the mounting base 310 descends to the limit position during the descending process, the first subdivision 317 of the mounting base 310 will contact the bottom cover 232 to limit the axial displacement during the descending process.

[0160] Optionally, a coaster 610 is further provided on the base 300 to provide cushioning, anti-scalding, and anti-slip properties.

[0161] It should be noted that one or more water cup placement slots 110 are provided on the bracket 100. Each water cup placement slot 110 can hold a cup body. At least one water cup placement slot 110 is connected with a base 300 and a mounting base 310 that can be raised and lowered in the cup bucket 230. It can be understood that if there are multiple water cup placement slots 110, each water cup placement slot 110 is provided with a base 300. Part of the base 300 can be designed to be movable, that is, part of the base 300 is connected to the mounting base 310 to achieve stepless lifting, and the rest is a fixed base 300. All the bases 300 can also be designed to be movable and steplessly liftable, which is not specifically limited here. Figure 3 As shown, one of them is a fixed base support 300, and the other is a movable base support 300 that can be raised and lowered steplessly.

[0162] The lifting cup holder provided in this embodiment works as follows:

[0163] Combination Figure 21 to Figure 24 , in the initial position state, that is, the base support 300 and the mounting base 310 are located at the first limit position, that is, the upper limit position. At this time, the mounting base 310 and the first stopper 233 on the upper edge of the cup barrel 230 are in contact. The first cam 342 is subjected to the counterclockwise rotation force of the first elastic member 350, so that the first cam 342 is always in contact with the guide rail clamping seat 321, preventing the guide rail clamping seat 321 from moving upward due to the upward force of the second elastic member 360. In this state, the rolling body 322 is always subjected to the downward force transmitted by the first cam 342, so the rolling body 322 is respectively in contact with the mounting base 310 and the guide rail column 500. In the absence of external force, the mounting base 310 will not move up and down, and the mounting base 310 and the base support 300 can be suspended in the initial position. At this time, there is a certain gap between the second cam 343 and the push plate 420 in the horizontal direction.

[0164] Combination Figure 25 to Figure 27During the descent process, downward pressure is applied to the base support 300 and the mounting base 310. For example, a water cup is placed on the base support 300, and the user presses the water cup, so that the base support 300 and the mounting base 310 are subjected to downward pressure, that is, the mounting base 310 is subjected to the first external force. At this time, the mounting base 310 and the base support 300 move downward along the guide rail column 500 as a whole. The first cam 342 is continuously subjected to the counterclockwise rotation force of the first elastic member 350, so that the first cam 342 is always in contact with the guide rail clamping seat 321. Since the gap between the mounting base 310 and the guide rail column 500 gradually increases during the descent process, the first cam 342 will push the guide rail clamping seat 321 to move downward. Until the rolling body 322 moves down to contact the surfaces of the mounting base 310 and the guide rail column 500 respectively, thereby stopping the downward movement. Since the guide rail column 500 is designed as an inverted cone, the rolling body 322 will tightly embrace the guide rail column 500, so that the rolling body 322 will not move up, and can be suspended at the current position. Without the action of external force, the mounting base 310 and the bottom bracket 300 will not move up and down. At this time, the gap between the second cam 343 and the push plate 420 in the horizontal direction is reduced.

[0165] Combination Figures 28 to 30 , descending to the state of the lower limit position. If the user continues to press the water cup, the base 300 and the mounting base 310 will continue to be subjected to the downward pressure. At this time, the mounting base 310 and the base 300 move downward along the guide rail column 500 as a whole until the mounting base 310 touches the second stop portion 234 on the bottom cover 232 and cannot move further downward. The mounting base 310 stops moving downward and reaches the second limit position of the descent process, that is, the lower limit position. The first cam 342 continues to be subjected to the counterclockwise rotation force of the first elastic member 350, so that the first cam 342 is always in contact with the guide rail clamping seat 321. Since the gap between the mounting base 310 and the guide rail column 500 gradually increases during the descent process, the first cam 342 will push the guide rail clamping seat 321 to move downward. Since the rolling body 322 is arranged in the guide rail clamping seat 321, the guide rail clamping seat 321 descends and drives the rolling body 322 to descend together, until the rolling body 322 moves down to contact the surface of the mounting base 310 and the guide rail column 500 respectively, thereby stopping the downward movement. Since the guide rail column 500 is designed as an inverted cone surface, the rolling body 322 will tightly hold the guide rail column 500, so that the rolling body 322 will not move up, and can be suspended at the lower limit position. When not affected by external forces, the mounting base 310 and the bottom bracket 300 will not move up.

[0166] Combination Figure 31 to Figure 33When the lock is in the lower limit position and is not unlocked, the horizontal gap between the second cam 343 and the push plate 420 is reduced to zero, that is, the second cam 343 and the push plate 420 are in contact. In addition, at this time, the distance between the upper groove wall of the limit groove 411 and the upper end surface 422 of the push plate 420 is the largest, and the horizontal distance between the unlocking rod 410 and the push plate 420 is the smallest.

[0167] Unlocked state: the mounting base 310 is rising from the lower limit position.

[0168] Combination Figures 34 to 40 When the user presses the unlock button 400 on the upper bracket 100, the pressure is transmitted to the unlock rod 410 through the buffer washer 430, that is, the unlock rod 410 is subjected to a downward axial force. The unlock rod 410 moves downward, and because the lower end of the push plate 420 is limited by the axial limit plate 421 on the cup barrel 230, the push plate 420 moves horizontally under the action of the four-link 450, and the push plate 420 moves horizontally to the left in the illustrated position. After the push plate 420 moves horizontally, it squeezes the second cam 343, driving the second cam 343 to rotate in the clockwise direction, thereby causing the rotating shaft 341 and the first cam 342 to rotate in the clockwise direction. After the first cam 342 rotates clockwise, the downward holding force on the guide rail clamping seat 321 is reduced, and the guide rail clamping seat 321 moves upward under the action of the second elastic member 360, and the mounting base 310 moves upward under the action of the fourth elastic member 220, thereby realizing the rising of the mounting base 310 and the bottom bracket 300. When the pressure acting on the unlocking button 400 disappears, the downward axial force on the unlocking rod 410 disappears, the push plate 420 stops moving, the second cam 343 stops rotating, the first cam 342 stops rotating, and under the action of the first elastic member 350, the guide rail clamping seat 321 is abutted, so that the rolling body 322 is respectively in contact with the mounting base 310 and the guide rail column 500, thereby achieving hovering and locking at the current position.

[0169] Since the axial downward pressure on the unlocking rod 410 disappears, the push plate 420 stops moving. And the push plate 420 moves in the reverse direction under the action of the third elastic member 460, that is, in the horizontal direction ( Fig.36 The unlocking lever 410 rises to the initial state and the unlocking button 400 is reset.

[0170] The installation base 310 rises to the upper limit position.

[0171] When the user presses the unlock button 400 on the upper bracket 100, the pressure is transmitted to the unlock rod 410 through the buffer washer 430, that is, the unlock rod 410 is subjected to a downward axial force. The unlock rod 410 moves downward, and because the lower end of the push plate 420 is limited by the axial limit plate 421 on the cup barrel 230, the push plate 420 moves horizontally under the action of the four-link 450, and the push plate 420 moves horizontally to the left in the illustrated position. After the push plate 420 moves horizontally, it squeezes the second cam 343, driving the second cam 343 to rotate in the clockwise direction, thereby causing the rotating shaft 341 and the first cam 342 to rotate in the clockwise direction. When the unlock rod 410 moves downward to contact the upper end surface 422 of the push plate 420. At this time, the second cam 343 drives the first cam 342 to rotate clockwise, and there is a gap between the first cam 342 and the guide rail clamping seat 321, that is, the first cam 342 no longer resists the guide rail clamping seat 321. The guide rail clamping seat 321 moves upward under the action of the second elastic member 360, and the mounting base 310 moves upward under the action of the fourth elastic member 220, thereby realizing the rise of the mounting base 310 and the bottom bracket 300 until they rise to the upper limit position. The mounting base 310 is restricted by the first stopper 233 of the cup bucket 230 and stops rising. When the pressure acting on the unlocking button 400 disappears, the downward axial force on the unlocking rod 410 disappears, and the push plate 420 stops moving to the left. And the push plate 420 moves in the horizontal direction (close to the unlocking rod 410) under the action of the third elastic member 460. Fig.36 The unlocking lever 410 rises to the initial state and the unlocking button 400 is reset.

[0172] Since the force exerted by the push plate 420 on the second cam 343 disappears, the second cam 343 stops rotating. The first cam 342 abuts against the guide rail clamping seat 321 under the action of the first elastic member 350, so that the rolling body 322 abuts against the mounting base 310 and the guide rail column 500 respectively, realizing the suspension and locking at the current position, and returning to the initial upper limit position.

[0173] Combination Figure 41 to Figure 46 ,in, Fig.41 and Fig.42 What is shown is a schematic diagram of the matching of the second cam 343 and the push plate 420 when the mounting base 310 is located at the initial position, that is, the upper limit position. At this time, the distance between the second cam 343 and the push plate 420 is the largest. Fig.43 and Fig.44 What is shown is a schematic diagram of the matching of the second cam 343 and the push plate 420 when the mounting base 310 is suspended at a certain position in the middle. At this time, the distance between the second cam 343 and the push plate 420 is smaller than the distance in the initial position state. Fig.45 and Fig.46What is shown is a schematic diagram of the matching of the second cam 343 and the push plate 420 when the mounting base 310 is suspended at the lower limit position. At this time, the distance between the second cam 343 and the push plate 420 is zero, and the two are just in contact.

[0174] Combination Figure 47 to Figure 49 ,in, Fig.47 Schematic diagram of the matching of the axial clearance between the unlocking rod 410 and the push plate 420 at the limiting groove 411 in the initial state of the unlocking button 400. At this time, the unlocking button 400 is not subjected to force, the axial clearance between the unlocking rod 410 and the push plate 420 at the limiting groove 411 is the largest, and correspondingly, the horizontal distance between the push plate 420 and the unlocking rod 410 is the smallest. Fig.48 The figure is a schematic diagram of the matching of the axial clearance between the unlocking rod 410 and the push plate 420 at the limiting groove 411 when the unlocking button 400 is in a pressed state. At this time, the unlocking button 400 is subjected to downward pressing force, and the axial clearance between the unlocking rod 410 and the push plate 420 at the limiting groove 411 is reduced, and correspondingly, the horizontal distance between the push plate 420 and the unlocking rod 410 is increased. Fig.49 The figure is a schematic diagram of the matching of the axial clearance between the unlocking rod 410 and the push plate 420 at the limit groove 411 when the unlocking button 400 is pressed to the limit. At this time, the unlocking button 400 is subjected to downward pressure and is pressed to the limit position, and the axial clearance between the unlocking rod 410 and the push plate 420 at the limit groove 411 is zero, the upper groove wall of the limit groove 411 of the unlocking rod 410 is in contact with the upper end surface 422 of the push plate 420, and the unlocking rod 410 cannot continue to move downward axially. Correspondingly, the distance between the push plate 420 and the unlocking rod 410 in the horizontal direction is the largest.

[0175] In summary, the locking mechanism and lifting cup holder provided by the embodiments of the present invention have the following beneficial effects, including:

[0176] In the locking mechanism provided by the embodiment of the present invention, the mounting base 310 moves under the action of the first external force, and the pressing assembly 330 pushes the clamping body 320 to move in the mounting base 310 while maintaining the abutment against the clamping body 320, so that the clamping body 320 abuts the mounting base 310 against the fixed base, and locks the mounting base 310 at the current position. The gap between the inner surface of the mounting base 310 and the outer surface of the guide rail column 500 is designed to be gradual. The clamping body 320 is pressed by the cam pressing assembly 330, so that the clamping body 320 clamps the guide rail column 500, so that the mounting base 310 can stay at any position of the guide rail column 500.
