In this embodiment, the electronic device holder includes a main body 50, a support portion 60, and at least two holding portions. Wherein for simplicity of description, the two clamping portions are defined herein as the first clamping portion 31 and the second clamping portion 41, respectively.

Of course, the mounting structure is not limited to the above description, and other structures are also possible.

The main body 50 of the electronic device stand is not limited to the housing structure described herein, and may be in other forms, and only the structure related to the invention will be described herein, and other structures will not be described in detail.

Referring again to fig. 2, fig. 2 is a schematic diagram illustrating the connection of the main components inside the electronic device housing. In this embodiment, the casing has an installation cavity 50a, is equipped with first link unit 10 and second link unit 20 in the installation cavity 50a, and in this embodiment, first link unit 10 is the same with second link unit 20 structure, all includes first connecting rod 1a and second connecting rod 1b of mutual articulated, and the other end of first connecting rod 1a articulates in the inner wall of installation cavity 50a, and the articulated clamping body of the other end of second connecting rod 1b, clamping body and clamping part one-to-one, the two links firmly. The clamping body fixedly connected with the first clamping portion 31 is a first clamping body 30, and the clamping body fixedly connected with the second clamping portion 41 is a second clamping body 40. The first clamping body 30 is connected to the second link 1b of the first link unit 10, and the second clamping body 40 is connected to the second link 1b of the second link unit 20.

The first link unit 10 and the second link unit 20 are disposed bilaterally symmetrically with respect to the center vertical plane a of the line segment O1O 2. Wherein O1 is a hinge point of the first link unit 10 and the housing, and O2 is a hinge point of the second link unit and the housing.

The support portion 60 in the present application is used to support the clamped electronic device 80, and the support portion 60 may be fixedly connected to the main body 50 or may be attached to the link unit. In the embodiment, the supporting portion 60 is fixedly connected to the link unit, referring to fig. 2, the supporting portion 60 is disposed on a hinge shaft between the first link 1a and the second link 1b of the link unit, and a moving track of the supporting portion 60 is substantially the same as a moving track of the hinge position, and the moving track is an arc. For example, the support portion 60 on the left first link unit 10 reciprocates along an arc segment formed with the first link 1a as a radius with the point O1 as a center. The support portion 60 on the right second link unit 20 reciprocates along an arc segment formed with the first link 1a as a radius with the point O2 as a center.

Referring to fig. 3, fig. 3 is a housing structure in an embodiment of the present invention, in order to support an electronic device 80, a supporting portion 60 necessarily extends out of an installation cavity to the outside of the housing, that is, the housing is provided with a first opening 51, the supporting portion 60 extends out of the housing from the first opening 51, in this embodiment, the housing is provided with two first openings 51, and the supporting portion 60 on the first link unit 10 and the supporting portion 60 on the second link unit 20 respectively extend out of the two first openings to the outside of the housing. The shape and size of the first port may have various forms, not limited to the above description of the present application, as long as it does not interfere with the support of the electronic device 80 by the support 60 and the movement of the support 60 when supporting.

In this embodiment, the length of the first link 1a in the first link unit 10 and the second link unit 20 is smaller than the length of the second link 1b, that is, the first link unit 10 and the second link unit 20 are both link units having a stroke amplification function, that is, the first link 1a rotates for a small displacement to obtain a large displacement at the free end of the second link 1b, the clamping body is arranged at the free end, so as to satisfy the clamping of the screen electronic device 80 with a large size, and the stroke of the first link 1a of the link unit of the structure is small, so as to reduce the space occupied by the movement of the first link 1a, and further reduce the size of the housing installation cavity, which is beneficial to the miniaturization of the support. In conclusion, the connecting rod unit with the structure occupies a smaller space in movement, but the free end stroke is larger, so that the electronic equipment 80 with a wider screen and a narrower screen can be clamped in the smaller space at the same time, and the application universality is higher.

In this embodiment, the second link 1b of the first link unit 10 and the second link 1b of the second link unit 20 are arranged in parallel along the thickness of the bracket and intersect in a projection in a plane perpendicular to the thickness of the bracket, as shown in fig. 2, two hinge seats (positions of points O1 and O2 in the figure) arranged left and right are provided on the main body 50 for respectively being hinged to one end of the first link 1a of the two link units, the first link 1a of the first link unit 10 is hinged to the point O1, the first link 1a of the second link unit 20 is hinged to the point O2, the first link 1a of the first link unit 10 is connected to the first clamping body 30 on the right side through the second link 1b connected thereto, and the first link 1a of the second link unit 20 on the right side is connected to the second clamping body 40 on the left side through the second link 1b connected thereto.

The first clamping body 30 and the second clamping body 40 are also arranged symmetrically with respect to the central vertical plane a of the line segment O1O2 in this embodiment. Each of the clamping bodies has a predetermined length and is disposed at a predetermined angle with the transverse direction, and the outer ends of the two clamping bodies extend toward both sides of the main body 50, as shown in fig. 2, the first clamping body 30 and the second clamping body 40 extend obliquely upward, respectively. The interior tip and the sliding part sliding fit of each clamping body, the outer tip of clamping body has vertical section in order to form the clamping part, and the clamping part of two clamping bodies sets up relatively. As will be understood from fig. 1 to 3, the first clamping body 30 and the second clamping body 40 both extend from the inside of the housing to the upper side of the corresponding sides, so that the first clamping portion 31 and the second clamping portion 41 are located outside the housing. The first clamping body 30 and the second clamping body 40 are obliquely arranged, so that the distance between the two clamping parts can be increased.

Referring again to fig. 2, in this embodiment, a sliding slot 53 is further disposed in the housing accommodating cavity, each of the clamping bodies includes a sliding block, only the sliding block 32 at the inner end of the first clamping body 31 is labeled in fig. 2, and the sliding block 32 is disposed inside the sliding slot 53 and can slide along the extending direction of the sliding slot 53. That is, when the clamping bodies move under the driving of the link unit, the clamping bodies can only move along the extending direction of the sliding slot 53 under the cooperation of the sliding block and the sliding slot 53, so that the moving directions of the clamping parts of the two clamping bodies are also limited, and the clamping bodies can only move in the predetermined horizontal and longitudinal intervals. When the electronic equipment is clamped, when the supporting part 60 moves under the action of gravity of the electronic equipment, the first clamping part 31 and the second clamping part 41 can be relatively close to each other and are finally abutted against two side walls of the electronic equipment for clamping, so that clamping spaces matched with the electronic equipment with different widths are formed, and clamping requirements of the electronic equipment with different widths are met. Further, the moving direction of the clamping parts is restricted by the sliding parts, so that the two clamping parts can move at least in a preset interval in the longitudinal direction, and the two clamping parts cannot clamp the key 81 on the side wall of the electronic equipment. Particularly for the folding electronic device, the contact positions of the two clamping parts and the unfolding state and the folding state of the folding electronic device can be completely positioned outside the setting area of the key 81 on the side wall of the folding electronic device through the constraint of the sliding part.

In the example shown in fig. 2, the sliding grooves 53 are substantially distributed in the transverse direction, the clamping area matched with the clamped electronic device 80 formed by the two clamping portions and the supporting portion 60 which are configured together under the limitation of the sliding grooves 53 is not changed greatly in the longitudinal direction, the clamping portions can be changed in the non-key area of the side wall of the electronic device 80 all the time, that is, the first clamping portion 31 and the second clamping portion 41 do not clamp the key 81 on the side wall of the electronic device 80, and the arrangement positions of the key 81 on the side wall of the electronic device 80 are shown in fig. 5 and 6. It should be noted that the non-key area of the electronic device described herein refers to a location area where no key is provided. Ideally, the sliding slot 53 is disposed along a transverse direction, and referring to fig. 2, a direction in which the two clamping portions clamp the electronic device 80 is defined as a transverse direction, and correspondingly, a direction perpendicular to the transverse direction in a plane in which the parallel link units are located is defined as a longitudinal direction.

Taking the clamping of the foldable electronic device as an example, the actions of the components in the embodiment will be described in detail below.

When the foldable electronic device in the wide screen state is clamped, please refer to the dashed line structure of the link unit and the clamping body in fig. 1 and fig. 2 for the state schematic diagram of the electronic device support, and please refer to fig. 5 for the schematic diagram of the electronic device 80 in the clamped state.

When using this folded cascade electronic equipment of support centre gripping wide screen state, folded cascade electronic equipment contacts with supporting part 60 on two link units earlier, supporting part 60 receives the downward gravity action of folded cascade electronic equipment, will drive two link units and rotate in step, support the contact until two clamping parts and folded cascade electronic equipment's both sides wall, promptly under folded cascade electronic equipment action of gravity, the inward clamp force is applyed to the both sides wall of folded cascade electronic equipment to the inside motion of clamping part of both sides, two link unit motions reach the balance this moment, folded cascade electronic equipment is supported and is pressed from both sides tightly on the support.

When the foldable electronic device needs to be taken down, the foldable electronic device 80 is separated from the support portion 60 only by pulling the foldable electronic device upwards, the acting force on the support portion 60 disappears, and meanwhile the inward clamping force of the clamping portion also disappears, so that the foldable electronic device 80 can be easily taken down from the bracket.

When the foldable electronic device in the narrow-screen state is clamped, the state of the electronic device holder is schematically shown in fig. 1 and fig. 2, and the solid line structure of the link unit and the clamping body is shown, and the schematic view of the electronic device 80 in the clamped state is shown in fig. 6.

The clamping principle of the electronic device 80 is basically the same as that of the foldable electronic device in the wide-screen state, and is different from the wide-screen state in that the screen size of the electronic device in the narrow-screen state is small, the distance between the clamping parts on two sides and the screen is large, when the foldable electronic device in the narrow-screen state is supported on the supporting part 60, under the pushing of the gravity of the electronic device in the narrow-screen state, the supporting part 60 can drive the two first connecting rods 1a on two sides to rotate downwards by a large angle around the point O1 and the point O2 respectively, and meanwhile, the free ends of the second connecting rods 1b on two sides drive the clamping bodies to move inwards until the clamping parts on two sides clamp the side walls of the foldable electronic device, and the two connecting rod units and the foldable electronic device form a stable structure.

In this embodiment, the clamping force is generated by the gravity of the electronic device 80, which not only simplifies the mechanism and is beneficial to the miniaturization of the bracket, but also greatly reduces the friction between the clamping part and the electronic device 80 when the electronic device 80 is mounted and taken down, thereby protecting the electronic device 80.

The clamping principle of the other electronic devices 80 with different widths is the same as that of the foldable electronic device, and the description thereof is omitted here.

In order to further increase the clamping force between the two clamping portions and improve the clamping stability of the electronic device 80, a spring 70 may be further added in this embodiment, please refer to fig. 2, wherein the spring in the state of the dotted line is not shown in fig. 2 for clarity of illustration. One link unit may correspond to at least one spring 70, and fig. 2 shows a specific structure of one link unit corresponding to one spring 70, and the spring 70 may have one end fixed to the inner wall of the housing and the other end capable of being connected to one of the links of the link unit. The spring 70 can generate a force to clamp the clamping portion inward by its own restoring force, i.e., the spring 70 is used to provide an auxiliary clamping force to the clamping portion.

As shown in fig. 2, the spring 70 is located below the first link 1a, the lower end of the spring 70 is fixed to the main body 50, the upper end is connected to the supporting portion 60, and the spring 70 is under tension and applies a downward pulling force to the supporting portion 60. Of course, the spring 70 may be installed above the first link 1a, the spring 70 may be in a compressed state, and the spring 70 may apply a downward elastic force to the support portion 60 in the compressed state.

Of course, the connection manner of the spring 70 is not limited to the above description, and the spring 70 is not limited to the link connection with the connection unit, but may directly apply force to the clamping body.

The connection of the spring 70 and the housing, and the connection of the spring 70 and the connecting rod can be fixed relatively by welding, riveting, hooking or other mechanical connection methods.

When clamping electronic equipment 80 like this, electronic equipment 80 can be simultaneously the centre gripping under the clamping action of spring 70 and the two aspects of electronic equipment 80 self gravity location, except that rely on self gravity to produce inward clamping-force, the spring can provide supplementary clamping-force to the clamping part of centre gripping on this support, improves the centre gripping reliability.

The spring may be a coil spring, a conical spring, or the like, but may be other elastic members having elastic force generated by elastic deformation, such as rubber or others, besides the spring.

As can be seen from fig. 2, 4 and 6, when the electronic device support clamps the electronic device 80 with the minimum width, the second link 1b of the two link units has the maximum included angle with the transverse direction, and the larger the included angle between the second link 1b and the transverse direction is, the smaller the distance between the two clamping portions is, and the smaller the width of the screen that can be clamped by the support is, and accordingly, the wider the application range of the support is. However, the larger the included angle between the second connecting rod 1b and the transverse direction is, the self-locking phenomenon easily occurs when the connecting rod unit moves correspondingly, and the performance of the product is greatly reduced. Therefore, in order to avoid the link movement self-locking phenomenon, the rotation angle of the second link 1b needs to be limited, and the rotation angle limitation of the second link 1b can be realized by limiting the displacement of the clamping body.

In this embodiment, for the first clamping body 30 and the second clamping body 40, which are slidably disposed inside one sliding slot 53 at the same time, under the action of gravity of the electronic device 80, the two supporting portions 60 move downward at the same time, the sliding blocks 53 connected to the free ends of the two second connecting rods 1b slide toward the middle of the sliding slot 53, when the two sliding blocks abut against each other, the distance between the two clamping portions is minimum, and at this time, the included angle between the second connecting rod 1b and the transverse direction is at the maximum included angle, where the maximum included angle is less than or equal to 60 ° (including the range end point value), the maximum included angle between the second connecting rod 1b and the transverse direction may be arbitrarily selected within a range of 0 ° to 60 °, and the value may be determined according to the application environment of the rack product, for example, the maximum included angle may be 30 °, 45 °, 50 °, or 60 °, and the like. Therefore, on the premise that the flexible action of the connecting rod unit is met, the electronic equipment 80 with the screen as narrow as possible can be clamped by the support.

In this embodiment, the larger the distance between the two clamping portions is, the wider the screen can be clamped by the bracket, but the higher the position of the supporting portion 60 on the link unit is, i.e. the smaller the distance between the supporting portion 60 and the clamping portion is, and accordingly, the smaller the height of the clamping space formed by the clamping portion and the supporting portion 60 is, the weaker the clamping stability is.

In the electronic device stand according to the above embodiment, when the first link 1a in the link unit is located at the horizontal position, the horizontal distance between the two clamping portions is the largest under the requirement of ensuring the clamping stability of the electronic device 80. This can compromise the requirements of both the stability of the clamping of the electronic device 80 and the width of the clamped screen as much as possible.

The limitation of the critical positions of the second connecting rod 1b and the first connecting rod 1a in the connecting rod unit can be realized by the limitation of the positions of the clamping bodies, and certainly, the limiting structure of the corresponding connecting rod matching limitation can also be specially limited, for example, a limiting column and other structures are arranged in a shell installation cavity, and the corresponding connecting rod is limited at the critical position by the limiting column.

For the same link unit, the smaller the angle between the sliding slot 53 and the transverse direction is, the larger the maximum displacement of the clamping body in the transverse sliding direction is, but correspondingly, in order to avoid the clamping stagnation when the clamping body slides, the higher the requirement on the matching precision between the clamping body and the sliding slot 53 is.

Although the drawings only show the schematic diagram of the transverse arrangement of the sliding chute 53, in the case of not clamping the key 81 on the side wall of the electronic device 80, the sliding chute 53 is allowed to have a certain angle with the transverse direction, for example, in other embodiments, the angle between the sliding chute 53 and the transverse direction may range from 0 ° to 15 °, and the angle may be arbitrarily selected within the range, for example, the angle between the sliding chute 53 and the transverse direction may range from 3 °, 5 °, 8 °, 10 °, 12 °, or 15 °. When the sliding groove and the transverse included angle are in the range of 0-15 degrees, the clamping body can smoothly slide in a reciprocating mode through the sliding groove 53, the action flexibility of the connecting rod unit is high, and the support does not clamp the key 81 on the side wall of the electronic equipment 80 when clamping most of the electronic equipment 80.

The acquisition of the larger displacement of the clamping body is realized through the movement of the connecting rod unit, and the movement direction of the clamping body is restrained through the sliding groove, so that the clamping part of the clamping body and the supporting part 60 are jointly configured to form a clamping area matched with the non-key area of the clamped electronic equipment 80. The sliding portion for restricting the moving direction of the clamping body may not be limited to the sliding groove 53 of the above-described embodiment, but may have other structures, such as a slider or a combination of a slider and a sliding groove.

While the present application has been described above with reference to a crank unit of a crank rocker type structure formed by two links having the simplest structure, it will be understood by those skilled in the art that the structure of the link unit is not limited to the above-described link unit including only the stroke amplification function of two links, and may be a link structure having a stroke amplification function formed by two or more links. The mounting end of the link unit is hinged to the body 50 and the stroke-enlarging end is hinged to the gripping body.

For a link unit formed of two or more links, the arrangement of the support portion 60 may be the same as the above embodiment: the hinge shaft of the other end of the link hinged to the body 50 in each link unit extends outward in the axial direction to form a support portion 60. The arrangement is simple, the position of the supporting part 60 is relatively low, and a stable clamping area can be formed between the supporting part and the clamping part.

The contact position of the clamping part and the electronic device 80 may be additionally provided with an elastic material layer, such as rubber or silica gel. This reduces wear of the electronic device 80 by the clamping portion, and protects the electronic device 80. The elastic material layer can be integrated with the clamping part, for example, the elastic material layer is combined with the clamping part through processes such as vulcanization, of course, the elastic material layer can also be separated from the clamping part, for example, the elastic material layer is in a cap structure, the clamping part is sleeved with the cap structure, the process is simple, and the elastic material layer is convenient to replace after being worn.

The principles and embodiments of the present application are described herein using specific examples, which are only used to help understand the method and its core idea of the present application.
