As mentioned in the background, the rotating modules commonly used at present for electronic products or devices tend to have the same torque force required for rotating two ends, but most products and devices are subject to frequent reciprocating motion in the process of actual production and life. For example: the rotation stop function of the display screen is generally realized on the notebook computer through the two bilaterally symmetrical hinges, and the force required by the clockwise rotation and the anticlockwise rotation of the display screen is the same. Due to different working operation states, the requirements of actually required force in two directions of forward and reverse rotation may not be the same, and the constant torque force in the two directions causes difficulty in operation of personnel and waste of physical strength. For example: a cash register for a supermarket has a stop function of keeping any angle. The display screen needs to be lifted from the initial position to the signature position frequently to confirm the signature of the customer, and when the rotating module is lifted up, if a larger torque is kept, the rotating module causes operation difficulty, wastes more physical strength of the user, and even the whole machine can be lifted up together.
Referring to fig. 1-7, the adjustable two-way friction damped rotary connection of the present application is described in detail below.
As shown in fig. 1 and fig. 2, the rotary connection structure with adjustable bidirectional friction damping comprises a rotating shaft 1 and two sets of friction components 2 mounted on the rotating shaft 1 in a penetrating manner; the friction assembly 2 comprises a shaft sleeve 21, a first friction plate 22, a one-way bearing 23 and a damping adjusting piece 24, wherein the one-way bearing 23 is arranged on the rotating shaft 1 in a penetrating manner, the first friction plate 22 comprises an annular main body 221, the one-way bearing 23 is fixed in the annular main body 221, the first friction plate 22 is provided with a first friction matching surface, the shaft sleeve 21 is provided with a second friction matching surface, the shaft sleeve 21 is sleeved on the annular main body 221, the first friction matching surface is in abutting press fit with the second friction matching surface, and the damping adjusting piece 24 is used for adjusting positive pressure between the first friction matching surface and the second friction matching surface; the two groups of friction assemblies 2 are opposite in rotating direction around the rotating shaft 1.
Two sets of friction pack 2 wind the rotatable opposite direction of pivot 1, during rotation type connection structure forward rotation, the direction of turning to of first group friction pack 2 is the dead direction of lock, pivot 1 can drive first group friction pack 2 and rotate together, second group friction pack 2 is in the state of loosening, only pivot 1 is rotating taking place, during rotation type connection structure reverse rotation, first group friction pack 2 becomes the state of loosening, only pivot 1 is rotating taking place, second group friction pack 2 becomes the direction of locking, pivot 1 can drive second group friction pack 2 and rotate together.
Therefore, the friction force of the forward and reverse rotation of the rotary connection structure can be separately adjusted, and under the rotation requirement of some frequent actions and unnecessary great holding force, the damping adjusting piece 24 in the group of friction components 2 can be adjusted to reduce the positive pressure between the first friction matching surface and the second friction matching surface by adjusting the damping adjusting piece 24, so that the friction damping in the rotation direction, namely the rotation resistance, is reduced, the purpose of easily lifting or easily falling is achieved, the rotation operation is simple and convenient, and the physical force is saved. Meanwhile, the rotary connecting structure adopts positive and negative rotation, namely one group of friction components 2 plays a friction role during positive rotation, and the other group of friction components 2 plays a friction role during negative rotation, so that the same use frequency is realized, and the first friction plate 22 of each group of friction components 2 only bears half-frequency friction loss, so that the service life is longer than that of the traditional rotating component.
It should be noted that the two sets of friction components are rotatable around the rotating shaft in opposite directions by reversely mounting the two one-way bearings on the rotating shaft.
In this embodiment, a skirt 222 is disposed at one end of the annular main body 221, a mounting hole adapted to the annular main body 221 is disposed on the shaft sleeve 21, the first friction engagement surface is disposed on the skirt 222, and the second friction engagement surface is disposed on one side of the shaft sleeve 21; the other end of the annular main body 221 passes through the mounting hole from one side of the shaft sleeve 21, and the damping adjusting member 24 is connected to the other end of the annular main body 221 passing through the mounting hole, so as to press the skirt 222 against one side of the shaft sleeve 21, and further to press and fit the first friction fitting surface and the second friction fitting surface, that is, in this embodiment, the first friction fitting surface is located on the surface of the skirt 222 facing one side of the shaft sleeve 21.
Further, the mounting hole formed in the shaft sleeve 21 is a stepped hole, the stepped hole has a stepped surface located on one side of the shaft sleeve 21, the second friction fitting surface is located on the stepped surface, and the skirt 222 of the first friction plate 22 is attached to the stepped surface of the stepped hole, so that the first friction fitting surface of the first friction plate 22 is attached to and pressed against the second friction fitting surface of the shaft sleeve 21. Further, the damping adjusting member may be, for example, a nut, which is provided with a connecting hole adapted to the ring body, and the ring body 221 is screwed into the connecting hole. Specifically, an external thread is arranged on the outer surface of the annular main body 221, an internal thread is arranged on the inner end face of the connecting hole, and the damping adjusting piece 24 is in threaded connection with the first friction plate 22 through the matching of the external thread and the internal thread. The skirt 222 of the first friction plate 22 is pressed against one side of the sleeve 21 by tightening the damping adjuster 24.
Therefore, in the embodiment, the tightness of the fit between the first friction plate 22 and the shaft sleeve 21 can be adjusted by the damping adjusting member 24, that is, when the damping adjusting member 24 is screwed in the direction of the skirt 222, the first friction plate 22 and the shaft sleeve 21 can be tightly attached together, and the rotation resistance of the first friction plate 22 is larger under the friction action of the first friction fit surface and the second friction fit surface; when the damping adjusting member 24 is unscrewed away from the skirt 222, the fit between the first friction plate 22 and the boss 21 can be made looser, so that the rotational resistance of the first friction plate 22 can be reduced. Thus, when it is desired that one of the friction packs 2 rotate without the other friction pack 2 rotating, the damping adjuster 24 of each friction pack 2 may be adjusted accordingly to adjust the resistance to friction pack rotation accordingly.
Wherein, two bushings 21 of two sets of friction components 2 are detachably connected. Specifically, the shaft sleeve 21 is of an annular structure, a plurality of threaded holes are uniformly formed in each shaft sleeve 21 along the circumferential direction of the shaft sleeve, and the threaded holes in the two shaft sleeves 21 are connected through bolts. In one implementation, the number of threaded holes is three. The advantage of using a detachable connection is that damage to the sleeve 21 of one friction pack 2 does not affect the normal use of the sleeve 21 of the other friction pack 2.
The two groups of friction assemblies 2 are fixedly connected through the two shaft sleeves 21, and the installation directions of the two one-way bearings 23 of the two friction assemblies 2 are opposite.
As can be seen from the above, the two sets of friction assemblies 2 mounted on the rotating shaft 1 are connected into a whole, the rotatable directions of the two friction assemblies 2 are determined by the two unidirectional bearings 23 mounted in opposite directions, and the specific process is as follows: when rotation type connection structure forward is rotatory, the inside one-way bearing 23 of a set of friction pack 2 turns to the dead direction of lock, pivot 1 can drive the bearing in this set of friction pack 2 and first friction disc 22 rotate together, the shirt rim 222 of first friction disc 22 plays the frictional damping effect with the contact department of axle sleeve 21 mounting hole, the rotatory resistance of increase forward, the one-way bearing 23 of another set of friction pack 2 is in the state of loosening, only pivot 1 is taking place to rotate, when rotation type connection structure reverse rotation, the one-way bearing 23 of first set of friction pack 2 becomes the state of loosening, only pivot 1 is taking place to rotate, the inside one-way bearing 23 of second set of friction pack 2 becomes the dead direction of lock, pivot 1 can drive the bearing in the second set of friction pack 2 and first friction disc 22 and rotate together.
As shown in fig. 3 to 7, in the present embodiment, the friction assembly 2 further includes a second friction plate 25, and the second friction plate 25 is sleeved on the annular main body 221 and located between the other side of the sleeve 21 and the damping adjustment member 24. The tightness of the fit of the second friction plate 25 and the other side of the shaft sleeve 21 can be adjusted by the thread matching action of the damping adjusting member 24 and the annular main body 221, which is similar to the tightness adjusting manner of the fit of the first friction plate 22 and the shaft sleeve 21, and will not be described herein again.
Under the condition that the rotating shaft 1 drives the bearing in the friction component 2 and the first friction plate 22 to rotate together, the skirt 222 of the first friction plate 22 is in contact with one side of the shaft sleeve 21, the second friction plate 25 is in contact with the other side of the shaft sleeve 21, and the second friction plate 25 and the first friction plate 22 cooperate to generate friction damping on two sides of the shaft sleeve 21 simultaneously, so that the friction damping generated by the corresponding friction component 2 is further increased, and the rotation resistance is increased. If the second friction plate 25 is not tightly connected to the first friction plate 22, during the rotation of the first friction plate 22, the second friction plate 25 may rotate relative to the first friction plate 22, and although a certain frictional resistance may be applied to the rotation of the first friction plate 22, the frictional force between the second friction plate 25 and the shaft sleeve 21 may be reduced or even eliminated.
Therefore, in this embodiment, at the joint between the second friction plate 25 and the first friction plate 22, at least one first installation plane 2211 is disposed on the annular main body 221 of the first friction plate 22, a second installation plane 251 adapted to each of the first installation planes 2211 is disposed on the second friction plate 25, and the second installation plane 251 and the first installation plane are attached to each other. Specifically, there are two first mounting surfaces and two second mounting surfaces, respectively, where the two first mounting surfaces 2211 are symmetrically disposed about a center line of the rotating shaft 1, and the two second mounting surfaces are symmetrically disposed about the center line of the rotating shaft 1. The second installation plane 251 is matched with the first installation plane to fix the relative position of the second friction plate 25 and the first friction plate 22, so that the second friction plate 25 and the first friction plate 22 rotate simultaneously, and the problem that the second friction plate 25 cannot rotate synchronously with the first friction plate 22 because the second friction plate 25 is not matched with the first friction plate 22 tightly is solved. The first friction plate 22 and the second friction plate 25 generate frictional damping with the sleeve 21, thereby further increasing the rotational resistance.
In this embodiment, an elastic connecting member 26 is disposed between the second friction plate 25 and the damping adjusting member 24, and the elastic connecting member 26 is in contact with the second friction plate 25 and the damping adjusting member 24, respectively. By adjusting the position of the damping adjustment member 24 on the annular body 221, the compression state of the elastic connection member 26 can be adjusted, and when the elastic connection member 26 is in the compression state, an elastic force can be generated on the second friction plate 25, so as to push the second friction plate 25 toward the first friction plate 22. Therefore, by controlling the compression amount of the elastic connecting piece 26, the pressing force of the first friction plate 22 and the second friction plate 25 on the shaft sleeve 21 can be adjusted, so that the friction force among the first friction plate 22, the second friction plate 25 and the shaft sleeve 21 is changed, and the aim of accurately adjusting the rotation resistance is fulfilled. The elastic connecting pieces 26 are elastic pieces, the number of the elastic pieces can be selected according to the range of the rotation resistance to be adjusted and the installation space in the actual assembly process, and three elastic pieces are used as an achievable mode.
In other embodiments, if the installation space is relatively large, in the above-described friction assembly 2, the elastic connection member 26 includes a spring, and the spring replaces the elastic washer, so that the spring has a longer service life relative to the elastic washer, and the range of adjusting the rotation resistance is larger.
With continued reference to fig. 1 and 2, the present invention further provides a rotary support apparatus including the above-described adjustable bidirectional frictional damping rotary connection structure.
The rotary supporting device comprises a fixed base 4, a two-way bearing 5, a rotary support 3 and the rotary connecting structure, the two-way bearing 5 is arranged in the fixed base 4, the rotary support 3 is arranged on the fixed base 4, the rotary shaft 1 penetrates through the fixed base 4, the two-way bearing 5 and the rotary support 3, the rotary support 3 is riveted with the rotary shaft 1, the rotary shaft 1 and the rotary support 3 form a whole and synchronously rotate with the rotary shaft 1 in the rotating process, the structure and the appearance of the rotary support 3 are not further described here, and the rotary supporting device can be specifically limited according to the needs of products. The two friction components 2 are connected together to form the rotary connecting structure, the friction module is sleeved on the rotating shaft 1, and the structure of one shaft sleeve 21 is changed to match the structure on the fixed base 4, so that the state that the friction module can be locked by screws is achieved. For example: ear plates are mounted on both sides of the annular structure of the sleeve 21 for mating and connection with corresponding structures on the stationary base 4.
Because the installation directions of the two one-way bearings 23 of the two friction assemblies 2 in the rotary connecting structure are opposite, when the rotary bracket 3 is rotated in the forward direction, the rotary connecting structure rotates in the forward direction, the one-way bearings 23 in one group of friction assemblies 2 are rotated to be in a locking direction, the one-way bearings 23 in the other group of friction assemblies 2 are in a loosening state, and only the rotating shaft 1 rotates; when the rotating bracket 3 rotates reversely, the one-way bearing 23 of the first group of friction components 2 becomes a loosening state when the rotary connecting structure rotates reversely, only the rotating shaft 1 rotates, and the one-way bearing 23 in the second group of friction components 2 becomes a locking direction.
The rotary connection structure of the present embodiment is further explained and illustrated with reference to specific application scenarios.
Taking the cash register for supermarket as an example shown in fig. 8, the above mentioned product is a display screen, the display screen needs to maintain the stop function of any angle, two rotation angle states of the display screen are shown in the figure, the definition requirement of the product is that the display screen needs to be frequently lifted from the position a to the position B for signature confirmation of customers, the tightening force of the damping adjusting piece 24 of the friction component 2 in the direction is adjusted to be in a smaller state, the tightening force of the damping adjusting piece 24 of the friction component 2 providing friction damping in the opposite direction is in a larger state, so that the rotary connecting structure is easy to rotate in the lifting operation, the rotary bracket 3 bearing the display screen is easier to adjust, and in the process of customer signing, the rotary resistance in the opposite direction is larger, so the rotary bracket 3 bearing the display screen is not easy to be pressed down, the signature of a customer is not influenced, and the stop function at any angle can be better ensured.
