Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the present invention.

Fig. 1 is a schematic structural diagram of a stent provided according to an embodiment of the present application.

As shown in FIG. 1, in this embodiment, the stand includes a base 110, a plurality of arms 120,130,140, and a carrier 150.

A plurality of arms 120,130,140 are pivotally connected end to end. The base 110 is connected to one end of an integral assembly of a plurality of arms 120,130, 140. The carrier device 150 is rotatably coupled to the other end of the integral plurality of arms 120,130, 140.

The loading device 150 may be used to carry an image pickup apparatus such as a camera. The carrier device 150 may, for example, comprise a clamping mechanism for carrying the camera device in a clamped manner. The carrying device 150 may also include a magnetic member, for example, so as to cooperate with a magnet provided on the image capturing apparatus to carry the image capturing apparatus by means of magnetic attraction.

It should be understood that the specific form of the carrier device 150 is not limited thereto, and those skilled in the art can select an appropriate form according to actual needs, and the embodiment of the present application is not limited to the specific form of the carrier device 150.

It will be appreciated that although the number of arms of the stand shown in fig. 1 is 3, in other embodiments of the present application, the number of arms is not limited to 3. For example, in other embodiments of the present application, the number of arms may be 2, or may be 4 or more. The number of arms included in the bracket is not particularly limited in the embodiments of the present application.

Because the support is provided with a plurality of support arms which are connected end to end in a rotatable way, and the carrying device is also connected with one end of the whole body formed by the plurality of support arms in a rotatable way, when the support is used for supporting the camera shooting equipment, the position and the angle of the camera shooting equipment have a larger adjusting range, thereby being capable of better meeting the use requirements of users.

In some embodiments, the number of arms may be 3. 3 arms can significantly increase the adjustability range of the stand relative to 2 arms. But 4 or more arms do not significantly increase the adjustability range of the stand relative to 3 arms.

In order to ensure that the position of the image pickup apparatus can have a large adjustable range, the length of the arm cannot be set too short in general. When the support is stored, in order to reduce the space occupied by the support as much as possible, the length of the support arm does not need to be too long.

To address this issue, in some embodiments of the present application, at least one of the plurality of arms may be a telescoping arm.

It should be understood that any one or more of the plurality of arms may be a telescopic arm, and all of the plurality of arms may also be telescopic arms, and the embodiments of the present application are not limited thereto.

When the telescopic support arm is used, the telescopic support arm can be adjusted to the extending state to increase the adjustable range of the position of the camera shooting device, and after the telescopic support arm is used up, the telescopic support arm can be adjusted to the contracting state to reduce the space occupied by the support. Through setting up scalable support arm, not only can increase the adjustable range of camera equipment's position, but also can reduce the shared space of support when accomodating.

It should be understood that there are many ways to implement the retractable arm, and the embodiments of the present application are not limited thereto.

The following provides an implementation of a telescopic boom in conjunction with the accompanying drawings.

FIG. 2 is a schematic structural view of a mounting arm according to an embodiment of the present application, and FIG. 3 is a schematic end view of the mounting arm shown in FIG. 2 at A-A.

Referring to fig. 2 and 3, in this embodiment, the arms include an inner arm 210 and an outer arm 220. Inner arm 210 is telescopically inserted into cavity 222 of outer arm 220.

The telescopic function of the support arm is realized by arranging the outer support arm with a hollow structure and the inner support arm which is telescopically inserted into the cavity of the outer support arm.

In some embodiments, referring again to fig. 1, the first arm 120 includes a first inner arm 121 and a first outer arm 122. The second arm 130 includes a second inner arm 131 and a second outer arm 132. The third arm 140 includes a third inner arm 141 and a third outer arm 142.

In the use process, if the outer support arm and the inner support arm rotate relatively, the support can shake, so that the camera shooting device is unstable, and the shooting effect is influenced.

To address this problem, in some embodiments, the cross-sectional shape of the cavity of the outer leg is the same as the cross-sectional shape of the inner leg and is non-circular.

In other words, the cross-sectional shape of the inner surface of the cavity of the outer leg is the same as the cross-sectional shape of the outer surface of the inner leg and is non-circular.

It is understood that the sectional shape may be a sectional shape when a plane perpendicular to the expansion and contraction direction of the outer arm and the inner arm is taken as a section.

It should be understood that the same shape means having the same shape. For example, when the cross-sectional shape of the cavity of the outer leg is rectangular, the cross-sectional shape of the inner leg is also rectangular. The same shape does not mean exactly equal size.

It will be appreciated that when the cross-sectional shape of the cavity of the outer leg is circular, the cavity of the outer leg is cylindrical. Likewise, when the cross-sectional shape of the inner arm is circular, the inner arm is cylindrical. Obviously, when the cavity of the outer arm and the inner arm are both cylindrical, the outer arm and the inner arm are more likely to rotate, which is detrimental to the stability of the stent.

It will be appreciated that when the cross-sectional shape of the cavity of the outer leg is the same as the cross-sectional shape of the inner leg and is non-circular, the shape of the cavity of the outer leg and the shape of the inner leg can be used to prevent relative rotation of the outer and inner legs.

For example, when the cross-sectional shape of the cavity of the outer leg and the cross-sectional shape of the inner leg are polygonal, i.e., the shape of the cavity of the outer leg and the shape of the inner leg are prisms, the side edges of the prisms can be used to prevent relative rotation of the outer leg and the inner leg.

It should be understood that the cross-sectional shape of the cavity of the outer arm and the cross-sectional shape of the inner arm are not limited to a polygon, and may also be an ellipse, or other non-circular shapes, which are not limited in the embodiments of the present application.

The cross-sectional shape of the cavity of the outer support arm and the cross-sectional shape of the inner support arm are set to be the same non-circular shape, so that the relative rotation of the outer support arm and the inner support arm can be prevented by utilizing the shapes of the cavity and the inner support arm, and the stability of the support is improved.

Preferably, in some embodiments of the present application, referring again to fig. 3, (the inner surface of) the cavity 222 of the outer leg 220 may be rectangular in cross-sectional shape, while (the outer surface of) the inner leg 210 is also rectangular in cross-sectional shape.

Compared with other shapes, the rectangular structure is simple, the processing cost is low, and the stability is relatively high.

Although the shape of the cavity of the outer leg and the shape of the inner leg may be used to prevent relative rotation of the inner and outer legs. However, if the clearance between the cavity and the inner arm is large, the inner arm and the outer arm can still rotate relatively in a small amplitude, which is not favorable for the stability of the bracket.

Thus, in some embodiments of the present application, the clearance between the cavity of the outer support arm and the inner support arm is less than a predetermined value to further prevent relative rotation of the outer support arm and the inner support arm.

In other words, the clearance between the inner surface of the cavity of the outer leg and the outer surface of the inner leg is less than a preset value to further prevent relative rotation of the outer leg and the inner leg.

It will be understood that the clearance is the distance from the inner surface of the cavity of the outer leg to the corresponding location of the outer surface of the inner leg. Taking the arm shown in fig. 3 as an example, in this embodiment, the clearance refers to any one of a, b, c, and d.

Considering that the gap is not the same at each location, in certain embodiments of the present application, the gap may refer to the maximum gap between the inner surface of the cavity of the outer stent leg and the outer surface of the inner stent leg.

It will be appreciated that the smaller the clearance between the cavity of the outer arm and the inner arm, the more difficult it is for the outer arm and the inner arm to rotate relative to one another. In order to ensure that the relative rotation of the outer support arm and the inner support arm is reduced as much as possible on the premise of realizing the extension and retraction, the preset value may be set to 1mm, for example, also may be set to 0.5mm, for example, also may be set to 0.1mm, and the specific value of the preset value is not limited in this application.

After the length of the support arm is adjusted, the positions of the outer support arm and the inner support arm need to be fixed so as to prevent the outer support arm and the inner support arm from sliding relatively along the telescopic direction when in use.

Thus, in some embodiments of the present application, referring again to fig. 2 and 3, the inner support arm 210 is also a hollow structure. A slidable slider 241 is disposed in the cavity 212 of the inner arm 210.

The outer arm 220 has a first elongated hole 221. The inner arm 210 has a second elongated hole 211. The length direction of the first and second elongated holes 221 and 211 is the extension and contraction direction of the outer and inner struts 220 and 210. The slider 241 is provided with a screw hole 242.

Fasteners 231,232 are cooperatively provided with slider 241. The fasteners 231,232 include a shank 232 and a head 231 fixedly disposed at one end of the shank 232. The end of the rod portion 232 remote from the head portion 231 passes through the first and second elongated holes 221 and 211 and is screw-engaged with the screw hole 242 of the slider 241.

The distance between the head of the fastener and the sliding block can be shortened by rotating the fastener, so that the head of the fastener and the sliding block can be used for clamping the parts of the inner support arm and the outer support arm between the head of the fastener and the sliding block, and the relative sliding between the outer support arm and the inner support arm is prevented.

If the slider is rotatable within the inner cavity of the inner support arm, this can result in the threaded bore of the slider being offset from the elongated bores of the inner support arm and outer support arm when the fastener is disengaged from the slider, so that the fastener cannot be threaded into the threaded bore when it is desired to engage the fastener.

To address this issue, in some embodiments of the present application, the cross-sectional shape of the slider may be the same as the cross-sectional shape of the inner cavity of the inner arm and may be non-circular.

In other words, the cross-sectional shape of the outer surface of the slider may be the same as the cross-sectional shape of the inner surface of the inner lumen of the inner support arm and be non-circular.

It is understood that the sectional shape may be a sectional shape when a plane perpendicular to the expansion and contraction direction of the outer arm and the inner arm is taken as a section.

The cross-sectional shape of the slider and the cross-sectional shape of the inner cavity of the inner arm may be polygonal, elliptical, or other shapes besides circular, which is not limited in the embodiments of the present application.

Preferably, in some embodiments of the present application, the cross-sectional shape of the slider and the cross-sectional shape of the inner cavity of the inner arm may be rectangular.

The cross-sectional shape of the inner cavity of the inner support arm and the cross-sectional shape of the sliding block are set to be the same shape and are non-circular, so that the sliding block can be prevented from rotating in the inner cavity of the inner support arm, and the problem that a fastener cannot be screwed into a threaded hole due to deviation of the threaded hole and the strip hole is solved.

To further prevent the slider from rotating within the inner cavity of the inner arm, in some embodiments of the present application, the clearance between the slider and the inner cavity of the inner arm is less than a predetermined value to prevent the slider from rotating within the inner cavity of the inner arm.

It will be understood that the clearance is the distance from the inner surface of the cavity of the inner arm to the corresponding position of the outer surface of the slider. Taking the arm shown in fig. 3 as an example, in this embodiment, the clearance refers to any one of the distances e, f, g, and h.

Considering that the clearance at each location is not the same, in some embodiments of the present application, the clearance may refer to the maximum clearance between the inner surface of the cavity of the inner arm and the outer surface of the slider.

It will be appreciated that the smaller the gap between the cavity of the inner support arm and the slider, the less likely the slider will rotate within the cavity of the inner support arm. In order to ensure that the slider can slide in the cavity of the inner arm and reduce the relative rotation as much as possible, the preset value may be set to 1mm, for example, also may be set to 0.5mm, for example, also may be set to 0.1mm, and the specific value of the preset value is not limited in this application.

The gap between the sliding block and the cavity of the inner support arm is smaller, so that the sliding block can be further prevented from rotating in the cavity of the inner support arm.

Considering that the image pickup apparatus generally needs to be connected to the connection line, the connection line is generally placed at will when the image pickup apparatus is clamped to the loading device, which may cause inconvenience to the user. For example, the connection lines may become tangled when adjusting the stent. For another example, when the teacher needs to photograph the example he is writing, the connecting line may fall within the photographing area.

To address this issue, in some embodiments of the present application, a wire hanging structure is provided on at least one of the plurality of arms. The connecting wire can be hung on the support arm through the wire hanging structure, so that inconvenience brought to a user due to the fact that the connecting wire is entangled or enters a shooting area is avoided.

Taking the stand shown in fig. 1 as an example, in this embodiment, the wire hanging structures 160 are respectively disposed on the support arms 120,130 and 140.

It can be understood that the wire hanging structure may be disposed on any one or any several of the plurality of support arms, or may be disposed on each support arm, which is not limited in this embodiment of the present application.

It can be understood that only one wire clamping structure may be provided on the same support arm, and a plurality of wire clamping structures may also be provided on the same support arm, which is not limited in this application.

The wire hanging structure may be, for example, a clip provided on the arm. The wire hanging structure can also be a hook arranged on the support arm, for example. The wire hanging structure can also be a thread gluing arranged on the support arm, for example. The embodiment of the present application is not limited to the specific implementation manner of the wire hanging structure.

Preferably, referring again to fig. 1, the wire hanging structure 160 may be a hook 160 shaped like a letter C. Compared with a clamp or a thread gluing, the hook is more convenient to use. Meanwhile, since the hook 160 has a contracted opening, the connection wire can be effectively prevented from falling off from the hook 160.

Because the wire hanging structure is arranged on the support arm, the connecting wire can be hung on the support arm, so that inconvenience brought to a user due to the fact that the connecting wire is entangled or enters a shooting area is avoided.

In some embodiments, the wire hanging structure may be disposed on the outer arm.

It can be understood that when the support arm is composed of the telescopic inner support arm and the telescopic outer support arm, the wire hanging structure is arranged on the outer support arm, and the influence of the wire hanging structure on the telescopic function of the support arm can be avoided.

For example, referring again to FIG. 1, a wire hanging structure 160 can be disposed on first outer arm 122, second outer arm 132, and third outer arm 142, respectively.

To further increase the range of adjustability of the position and angle of the imaging device, in some embodiments of the present application, the arm of the plurality of arms that is coupled to the base is rotatable relative to the base.

The arm can rotate relative to the base, although the adjustable range of the position and angle of the camera device can be improved. However, in the use process, if the support arm rotates relative to the base, the support can shake, and therefore the shooting effect of the camera shooting device is affected.

Fig. 4 is a schematic structural diagram of a joint between a support arm and a base of a support according to an embodiment of the present application.

In this embodiment, as shown in FIG. 4, the base 510 is provided with receptacles 511, 512. The jacks 511,512 include a first section 511 and a second section 512. The first section 511 has a smaller aperture than the second section 512.

The arm of the plurality of arms coupled to base 510 includes a non-stab section 521 and a stab section 522. The insertion section 522 is rotatably inserted into the insertion holes 511, 512. By shaping or sizing the first section 511 and the non-inserted section 521, the non-inserted section 521 can be blocked by the first section 511 from the receptacles 511, 512.

The end of the insertion section 522 remote from the non-insertion section 521 is provided with a snap ring 523. The insertion section 522 is sleeved with an elastic member 530. The elastic member 530 may be a spring, for example. By being shaped or sized, the resilient member 530 is captured between the first segment 511 and the snap ring 523.

The pressing force of the elastic member can increase the friction force of the contact part between the arm and the base, so that certain damping exists when the arm and the base are rotated. By the arrangement, a user can be allowed to apply certain force to rotate the support arm when adjusting the camera equipment, and the support arm can be prevented from rotating relative to the base when in use, so that the stability of the support is improved.

There are various ways to achieve a rotatable connection between adjacent arms, which is not limited in this application. For example, the two adjacent arms can be connected in a hinged manner in a rotatable manner in a plane. For another example, a universal joint may be used between two adjacent arms to achieve a rotational connection in multiple planes.

One possible implementation is given below with reference to the accompanying drawings.

Fig. 5 is a schematic structural diagram of a joint between two adjacent support arms according to an embodiment of the present application.

As shown in fig. 5, in this embodiment, first arm 410 and second arm 420 are a pair of adjacent arms of a plurality of arms.

The end of first arm 410 adjacent to second arm 420 includes a first portion 411 and a second portion 412 disposed opposite to each other. The first portion 411 has a first through hole 413. The second portion 412 has a second through hole 414 therein.

The end of second arm 420 adjacent to first arm 410 is interposed between first portion 411 and second portion 412. A third through hole 421 is formed at an end of the second arm 420 close to the first arm 410.

In this embodiment, the bracket further comprises a bolt 431 and a nut 432. The rod of the bolt 431 passes through the first through hole 413, the third through hole 421 and the second through hole 414 in sequence, and is screwed with the nut 432.

When the adjacent support arms need to be rotated, the bolts and the nuts can be loosened, so that the included angle between the two adjacent support arms can be adjusted conveniently. After the adjustment is completed, the bolt and the nut can be screwed, and the friction force between the contact surfaces is increased by pressing the contact surfaces of the first connecting part, the second connecting part and the third connecting part, so that the relative rotation between the support arms is prevented.

So set up, the user only needs loosen bolt and nut and just can realize when the angle of needs adjustment support arm. Meanwhile, the connection mode can also ensure the stability between the connected support arms after adjustment, thereby improving the stability of the camera equipment.

Similarly, the arm of the plurality of arms that is connected to the carrier device may be connected to the carrier device in a similar manner.

This embodiment will be described in detail below with reference to the drawings.

Fig. 6 is a schematic structural diagram of a carrier device of a stand according to an embodiment of the present application.

In this embodiment, as shown in figure 6, an arm 620 attached to the staging device has a first portion 621 and a second portion 622 positioned opposite each other near one end of the staging device. The first portion 621 is provided with a first through hole (not shown). The second portion 622 is provided with a second through hole (not shown).

The carrier device comprises a connecting portion 615, and a through hole (not shown) is formed in the connecting portion 615. The bolt 631 sequentially passes through the first through hole, the through hole provided on the connection portion 615, and the second through hole to be screwed with the nut 632.

When the angle of the supporting arm and the carrying device needs to be adjusted by a user, the angle can be adjusted by loosening the bolt and the nut. Meanwhile, the connection mode can also ensure the stability between the adjusted rear support arm and the loading device, thereby improving the stability of the camera equipment.

In some embodiments of the present application, the carrier device may include a clamping mechanism, which may be used to clamp the camera device.

Camera devices such as a camera generally do not have a light compensation function, and when a dark area needs to be photographed, the photographing effect is often poor. For example, when a teacher needs an image pickup device to shoot down to take his example of handwriting, it is difficult for the image pickup apparatus to perform clear shooting due to insufficient light.

To address this issue, in some embodiments of the present application, the carrier device may include a first clamping mechanism and a second clamping mechanism. The first clamping mechanism may be used to clamp the image pickup apparatus. The second clamping mechanism can be used for clamping the light source so as to supplement light to the shooting area of the camera shooting device. The light source may be, for example, a led lamp, and the form of the light source is not limited in the embodiments of the present application.

Due to the fact that the second clamping mechanism used for clamping the light source is arranged, when the area with dark light is needed to be shot, the light source clamped by the second clamping mechanism can be used for supplementing light to the shooting area, and shooting quality is improved.

Obviously, two mutually independent clamping mechanisms may be provided to clamp the image pickup apparatus and the light source, respectively. However, to simplify the structure, in some embodiments of the present application, three clamping plates may be provided so as to form a clamping mechanism between two adjacent clamping plates.

In other words, the carrier device may include a first splint, a second splint, and a third splint disposed at intervals. The first clamping mechanism is composed of a first clamping plate and a second clamping plate and used for clamping the camera shooting device. The second clamping mechanism is composed of a second clamping plate and a third clamping plate and used for clamping the camera shooting device.

This embodiment is described in detail below with reference to the drawings.

Referring again to fig. 6, the carrier assembly includes a carrier 611. The stage 611 is provided at one end with a first clamping plate 612, and at the other end with a second clamping plate 613 and a third clamping plate 614.

The first clamping plate 612, the second clamping plate 613 and the third clamping plate 614 are respectively connected with the object stage 611 through different connecting rods. The connection rod is telescopically inserted in the stage 611.

An elastic tension structure is provided in the stage 611 for normally contracting the tie rods in the stage 611, i.e., maintaining the first clamping plate 612, the second clamping plate 613 and the third clamping plate 614 in a clamped state.

When it is necessary to clamp the image pickup apparatus, the first clamping plate 612 and the second clamping plate 613 may be opened, and the image pickup device may be placed between the first clamping plate 612 and the second clamping plate 613.

When it is desired to clamp the light source, the third clamping plate 614 may be spread apart, placing the light source between the third clamping plate 614 and the second clamping plate 613.

Compared with two independent clamping mechanisms, the three clamping plates are adopted to form the two clamping mechanisms, so that the structure can be simplified.

In some embodiments, multiple arms may rotate in the same plane.

In other words, the planes of rotation of the plurality of arms are coplanar.

For example, when the connection mode shown in fig. 5 is adopted, two adjacent support arms can rotate relatively in a rotation plane. If all the support arms adopt the connection mode, every two adjacent support arms have a rotation plane. When the rotation planes of all the adjacent support arms are coplanar, the plurality of support arms rotate in the same plane.

The arrangement of the plurality of support arms to rotate in the same plane reduces the adjustable range of the support but increases the convenience of adjustment of the support and the stability of the support.

Preferably, when an embodiment is used in which multiple arms rotate in the same plane, the connection shown in FIG. 4 can be used to connect multiple arms to the base. Thus, the bracket can be adjusted at a plurality of angles, thereby increasing the adjustable range of the bracket.

Preferably, in some embodiments of the present application, the carrier device is also rotatable in the plane of rotation of the plurality of arms, thereby further increasing the ease of adjustment and stability of the stand.

In other words, the plane of rotation of the carrier device may be coplanar with the plane of rotation of the plurality of arms.

In some embodiments, the carrier device can rotate in a plane perpendicular to the plane of rotation of the plurality of arms, thereby increasing the range of adjustability of the stand.

In other words, the plane of rotation of the carrier device may be perpendicular to the plane of rotation of the plurality of arms.

Considering that some cameras are provided with threaded holes for fixed attachment, in some embodiments, referring again to fig. 6, the carrier device may further include a mount 616. A mount 616 is provided on the stage 611 for fixedly attaching equipment on the stage 611.

The fixing member 616 may be, for example, a threaded rod provided on the stage 611, and the device on the stage may be, for example, an image pickup device provided with a threaded hole for fixing attachment.
