Description
Technical Field
The invention relates to a lifting device, in particular to a lifting type cup holder cover supporting locking device which can be applied to a cup holder in an automobile, has better synchronism and stability, large lifting span and reasonable and compact structure, and can realize real locking at different depths.
Background
The cup holder or the cup holder is an indispensable part in the automobile field, and manufacturers in the automobile part field invest lots of manpower and financial resources to research, design and produce the automobile part. However, at present, mineral water drunk by people is higher and is generally about 220 mm, and the height of the pop-top can is lower and is generally less than 100 mm, so that the cup holder with the larger depth needs to be adjusted at different heights.
Most of the existing technical schemes are depth-adjustable, namely, a bottom-pressing mode.
Or the different depths can be adjusted, but the locking type can be only achieved in a one-way mode, namely, the locking is lifted, and the locking cannot be lowered.
Application No. 201810162655.7 discloses a stepless lift cup stand, which uses gears, racks and an adjusting box (actually, it is an existing lockable unidirectional rotation damper) to implement lifting and stepless locking. In theory, a stepless locking is possible, but this stepless locking only locks the rise, but not the fall, and the rise is supported by the extension force of the spring.
The lifting cup holder or cup stand generally applies pressure which can enable the lifting support cover to descend on a cup or a mineral water bottle by hand, the spring can store energy when the lifting support cover descends, and the lifting support cover can automatically ascend by means of the reset of the spring.
The support cover can be suspended at different depths by using the upward extending force of the spring as a support, so that the cup cannot descend on the support cover.
If a cup is placed in the supporting cover, the cup has a certain self weight, and can be stopped under the support of the lower side spring under normal conditions, but when a vehicle bumps, the self weight impact force of the cup is about 25 newtons generally. Therefore, there is a problem in that the extension force of the spring is more than 25N in order to ensure that the cup does not fall even when the vehicle bumps. However, this requires more pressure to press the cup by hand during use, which is inconvenient. If the stretching force of the spring is not enough, the cup can sink downwards continuously under the impact of bumping of the vehicle.
And the spring is vertical setting, and the span of going up and down is big more, and the height of spring also can be big more, and the size difference that first the spring extends power is also big more, and second when the vehicle jolts, the spring can send out abnormal sound.
In view of the above, those skilled in the art have tried to develop a multifunctional locking device capable of being lowered, locked completely, and unlocked, which has better synchronization and stability, and larger lifting span, and can be applied to lifting type lid-supporting locking devices of single cup holder and double cup holder.

As shown in fig. 2 and 10, the lifting screw 11 is provided with a plurality of same threads, and the thread pitch of the threads is larger.
A plurality of wear-resistant strips are fixedly arranged on the upper side of the lifting support cover 2.
However, since the cup is placed on the lifting support cover 2 and has a certain weight, when the vehicle bumps, the cup will sink downward continuously under the impact of the weight of the cup and the up-and-down bumping force, so that the switch limiting head 22 is required to completely or to a certain extent lock the switch ratchet 21.
The pressing circulation switch is the pressing structure technology of the existing ball pen, and can be divided into three stages, namely the pen point is at the highest end when retracting, the pen point is at the middle end after extending out and locking, and the pen point is required to be pressed downwards by about two millimeters when unlocking, and belongs to the lowest end.
By utilizing the three-stage operation of pressing the circulation switch, the operation is matched with the interaction of the upper-end one-way switch groove, the middle-end switch locking groove and the lower-end unlocking chute of the limit sliding shaft 251 in the switch three-stage linkage groove 25, so that the single circulation, the locking and the unlocking states can be implemented, and the lifting support cover 2 can stay at the required depth in the cup holder 1.
For example, as shown in fig. 3 and 5: the switch pressing rod 27 and the pressing circulating switch are loosened and lifted (namely, when the ball-point pen head retracts), the switch limiting sliding shaft 251 is positioned in the one-way switch groove at the upper side of the switch three-stage linkage groove 25, and the width is larger; at this time, the switch link 23 is tightly attached to the switch ratchet 21 by the switch spring 256, but when the lift cap 2 is pressed down, the switch stopper 22 is pushed by the slope of the switch ratchet 21 and can move outward. Therefore, the lifting and lowering cover 2 can be lowered but cannot be raised.
For example, as shown in FIG. 6: the switch pressing rod 27 is pressed once (i.e. when the ballpoint pen point extends outwards to lock), the switch limiting sliding shaft 251 is located in the switch locking groove at the middle section of the switch three-stage linkage groove 25 at this time, the switch limiting head 42 cannot move outwards under the limitation of the multifunctional limiting piece 255 or the multifunctional limiting piece a257, at this time, the switch ratchet 21 cannot rotate, and the lifting support cover 2 is also locked, and cannot descend or rise.
Another example is shown in fig. 7: the switch pressing rod 27 is fully pressed to unlock, namely the ball-point pen needs to be pressed downwards by about two millimeters when unlocking, at the moment, the switch limiting sliding shaft 251 moves outwards under the action of the bevel edge of the lower unlocking groove in the switch three-stage linkage groove 25, the switch limiting head 22 is separated from the switch ratchet wheel 21, and at the moment, the lifting support cover 2 automatically rises under the reset action of the spring 36.
Under the action of pressing the cycle switch, two times of pressing form a cycle, and when not pressed, the lifting support cover 2 only can descend but cannot ascend.
As shown in fig. 8 and 9: the multifunctional limiting piece 255 and the multifunctional limiting piece a257 are two different design schemes, and the multifunctional limiting piece 255 is a spring piece with certain hardness, which can ensure that the switch ratchet 21 does not rotate under the conditions that the lifting support cover 2 has the weight of a cup and impact force is generated when a vehicle bumps, so that the lifting support cover 2 cannot descend. However, if an unexpected pressure occurs on the cup, for example, when a child sits on the cup carelessly, the elastic multi-functional limiting member 255 can rotate the switch ratchet 21, that is, the lifting lid 2 can be lowered, thereby preventing the mechanical structure in the cup holder from being damaged.
The multifunctional limiting member a257 and the connecting rod socket 24 can be formed at one time, so that the production and installation processes and the cost are simplified.
The free zone 211 on the switch ratchet 21 is designed for the purpose of: the lifting support cover 2 can directly descend or freely ascend to a certain depth in the upper section of the cup holder 1, and after the lifting support cover descends by 80 mm, the ratchet on the switch ratchet 21 contacts the switch limiting head 22 to implement a locking state. That is, the lifting/lowering lid 2 is freely lifted or lowered by 80 mm from the upper end of the cup holder and is not controlled by the switch. Setting of the neutral zone 211; the pop-top can beverage and lower items can be placed in a depth of 80 mm.
Adopt the technical scheme of multiunit lift screw 11 and lift swivel nut 12 in addition synchronous gear 31 and driven gear 32 combination, can let lift support lid 2 more stable in the lift of glass stand 1, its synchronism also can be better, still fine cushioning nature. However, the pitch of the threads in the lifting screw 11 and the lifting screw 12 needs to be larger because the lifting support cover 2 is forced to descend by pressure, and the lifting screw 11 is rotated and drives the synchronous gear 31 to rotate along with the descending of the lifting support cover 2, so that the spring 36 stores power, and the lifting support cover 2 can be automatically lifted when the spring 36 is reset. Therefore, the larger the pitch is, the smaller the pressure is used to lower the lifting support cover 2, and if the pitch is too small, the lifting screw 11 cannot be rotated when the lifting support cover 2 is pressed down, or the lifting screw 11 can be rotated only by the larger pressure, so that the lifting support cover 2 is lowered.
As shown in the drawings, the present application plots in a lifting screw 11 of 8 mm diameter: the thread pitch is designed to be around 30 mm, i.e. the thread is at an angle of around 60 degrees to the horizontal. And because the thread pitch is larger, a plurality of same threads are necessary to be arranged on the lifting screw rod 11, so that more threads on the lifting screw rod 11 are in fit contact with the threads in the lifting screw sleeve 12, and the threads have better tightness.
If the double-body cup holder is used, only a small gear with the same tooth mold is arranged between the two synchronous gears.
The foregoing detailed description of the invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed, and it is to be understood that various modifications, equivalents and improvements may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
