Description

Technical Field

[0001] This application provides a support device, and more particularly a support device with a quick-release function. Background Technology

[0002] Chinese Patent No. CN212617111U discloses an internally recessed double-rotation mechanism and a screen containing the mechanism, which integrates rotation and tilting / reverse tilting functions and is mounted on a support body. It includes a screen, a fixing component, a pivoting component, and a plastic cover. The fixing component has a circular cavity on one side and is connected to the screen. The pivoting component includes a movable disk and a pivoting block. The pivoting block is pivotally connected to the movable disk. The movable disk is immersed in the circular cavity, and the pivoting block protrudes outward and is exposed outside the circular cavity. The plastic cover is used to cover the circular cavity and has a body, an elastic hook, and an elastic element. The elastic hook is disposed on the body, and the elastic element passes through the elastic hook. The support body includes a column and a base for mounting the column.

[0003] While this design effectively reduces the size of the pivot component, it lacks a quick-release mechanism between the pivot and fixed components. If a quick-release structure were to be incorporated, the already reduced-size pivot component would have to be fitted with an external quick-release mechanism, resulting in an undesirable overall appearance.

[0004] In view of this, this application provides another support device with quick-release function, which enables quick installation and removal of the fixing component and the pivoting component, and the relevant quick-release design is not excessively exposed, thereby improving the overall aesthetics. Utility Model Content

[0005] This application provides a support device for supporting a display on a working surface. The support device includes: a support frame disposed on the working surface, comprising a column and an opening, the column extending substantially along a direction of gravity, and the opening formed in the column; a protruding neck disposed on the column and partially extending from the opening along a first axis; a support plate unit for supporting the display; a first pre-assembly disposed on one of the protruding neck and the support plate unit, and comprising a receiving groove and a through hole communicating with each other; and a second pre-assembly disposed on the other of the protruding neck and the support plate unit, and separable from it. The device is disposed in the receiving groove and includes a limiting hole; and an operating member is disposed in the through hole and can be changed between a first position and a second position along a second axis perpendicular to the first axis; wherein, when the second pre-assembly is received in the receiving groove and the operating member is located in the first position, the operating member is received in the limiting hole, and the second pre-assembly cannot be detached from the first pre-assembly, thereby connecting the carrier plate unit to the support frame; when the second pre-assembly is received in the receiving groove and the operating member is located in the second position, the operating member is detached from the limiting hole, and the second pre-assembly can be removed from the first pre-assembly.

[0006] As described above, when the second pre-assembly is gradually inserted into the receiving groove along the first axis, the second pre-assembly contacts the operating member, causing the operating member to gradually change from the first position to the second position until the through hole aligns with the limiting hole. At this point, the operating member returns to the first position and is received in the limiting hole.

[0007] As described above, the second pre-assembly also includes an inclined surface, and the operating member includes a chamfered portion. The extension direction of the inclined surface is oblique to the second axis and matches the inclination of the chamfered portion.

[0008] As described above, the operating element further includes a pin having a head and an extension connected to each other. The chamfered portion extends outward from the extension. The cross-sectional area of ​​the head is larger than that of the extension. The through hole has a first hole and a second hole connected to each other. The first hole is located between the receiving groove and the second hole, and the cross-sectional area of ​​the second hole is larger than that of the first hole. The extension passes through the first hole, and the head passes through the second hole.

[0009] As described above, the first pre-assembly also includes a stepped portion located between the first hole and the second hole. When the operating member is in the first position, the head abuts against the stepped portion, and the chamfered portion protrudes from the first hole. When the operating member is in the second position, the head moves away from the stepped portion, and the chamfered portion does not protrude from the first hole.

[0010] As described above, the operating element also includes a pull rod body having a helical section, a body section and a head section connected to each other. The pin is screwed into the helical section, the body section passes through the second hole body, and the head section is located outside the through hole.

[0011] As described above, the operating member further includes a baffle fixed to the first pre-assembly and having a through hole corresponding to the through hole. The body passes through the through hole, and the head is located outside the baffle. The cross-sectional area of ​​the through hole is smaller than the cross-sectional area of ​​the head. When the operating member is in the first position, the head abuts against the baffle. When the operating member is in the second position, the head moves away from the baffle.

[0012] As described above, the operating member also includes an elastic body that is fitted onto the body and abuts against the baffle and the head respectively, and constantly provides an elastic force that tends to keep the operating member in the first position.

[0013] As described above, when the operating member changes from the first position to the second position, the elastic force gradually increases, and when the operating member changes from the second position to the first position, the elastic force gradually decreases.

[0014] As described above, when the second pre-component is gradually inserted into the receiving groove along the first axis, the chamfered portion contacts the inclined surface and slides on the inclined surface, causing the operating member to gradually change from the first position to the second position until the chamfered portion disengages from the inclined surface. At this time, the pin is limited by the second pre-component and does not protrude from the first hole.

[0015] As described above, the second pre-assembly further includes a protruding tail block, the limiting hole being recessed in the protruding tail block, and the inclined surface being located at the end of the protruding tail block and spaced apart from the limiting hole.

[0016] As described above, the second pre-assembly further includes a bearing block and a tapering block. The bearing block is pivotally connected to the bearing plate unit and extends along the first axis. The tapering block extends from the bearing block along the first axis. The convex tail block extends from the tapering block along the first axis, and the radial cross-sectional area of ​​the convex tail block along the first axis is smaller than the radial cross-sectional area of ​​the tapering block along the first axis.

[0017] As described above, the second pre-assembly further includes two annular recesses, which are respectively disposed between the bearing block and the tapered block and between the tapered block and the convex tail block. The support device also includes two surrounding members, which are respectively disposed in the annular recesses.

[0018] In summary, the support device of this application does not require additional control components during the process of assembling the second pre-component into the first pre-component. It only needs to utilize the action between the chamfered part and the inclined surface and the elastic body to limit the second pre-component with the operating component when the second pre-component is fully assembled into the first pre-component. The assembly method is simple and convenient, and the relevant quick-release structures are all hidden inside the first pre-component without being excessively exposed, which can improve the overall aesthetics.

[0043] Please see Figure 1 and Figure 2The support device 1000 of this application is used to support a display 2000 on a working surface 3000. The support device 1000 includes a support frame 1, a protruding neck 2, a support plate unit 3, a first pre-assembly 4, a second pre-assembly 5, an operating member 6, and two surrounding members 7. The support frame 1 is disposed on the working surface 3000 (e.g., a desktop). The protruding neck 2 is inserted into the support frame 1. The support plate unit 3 is detachably disposed on the protruding neck 2 by means of the first pre-assembly 4 and the second pre-assembly 5, and is used to support the display 2000. The first pre-assembly 4 is disposed on the protruding neck 2, and the second pre-assembly 5 is disposed on the support plate unit 3 and is removably matched and connected to the first pre-assembly 4. The operating member 6 is disposed on the first pre-assembly 4, and the surrounding members 7 are disposed on the second pre-assembly 5. The structure of each component and their connection relationship will be described in detail below. Some of the diagrams show a gravity direction G, a first axis X1 and a second axis X2. The first axis X1 is not parallel to the gravity direction G, and the second axis X2 is perpendicular to the first axis X1.

[0044] The support frame 1 includes a base 11, a column 12, and an opening 13. The base 11 is generally a square plate placed on the working surface 3000, but it is not limited thereto; it can also be used to clamp a table or be locked to a wall. The column 12 extends substantially along the direction of gravity G, with one end located on the base 11, and the opening 13 is formed in the column 12. In this embodiment, the column 12 extends at a slight inclination to the working surface 3000; in other embodiments, the column 12 may extend perpendicular to the working surface 3000, and this is not a limitation.

[0045] The protruding neck 2 is inserted into the column 12, and part of it extends from the opening 13 along the first axis X1, protruding out of the column 12. Furthermore, the protruding neck 2 in this application is exemplified by a lifting and sliding type (e.g., having a trolley capable of reciprocating parallel to the direction of gravity G), but it can also be a fixed type. The support plate unit 3 includes a support plate and a tilting module. The support plate is used to connect to the display 2000, and the tilting module is disposed on the support plate and can tilt together with the support plate.

[0046] Please see Figure 3The first pre-assembly 4 includes a housing 41, a receiving groove 42, a through hole 43, and a stepped portion 44. One end of the housing 41 is connected to a protruding neck 2, forming an elongated hollow shell extending approximately along a first axis X1, and surrounding the receiving groove 42. The receiving groove 42 has an approximately L-shaped cross-section and is exposed at the end of the housing 41 away from the protruding neck 2. The through hole 43 extends along a second axis X2 through the housing 41 and has a first hole 431 and a second hole 432 connected to each other. The first hole 431 communicates with the receiving groove 42, and the second hole 432 is located away from the receiving groove 42 and exposed on the bottom side of the housing 41, such that the first hole 431 is located between the receiving groove 42 and the second hole 432. The cross-sectional area of ​​the second hole 432 is larger than the cross-sectional area of ​​the first hole 431. The stepped portion 44 is formed in the housing 41 and located between the first hole 431 and the second hole 432, and faces the bottom side of the housing 41 (i.e., away from the receiving groove 42).

[0047] Please refer to the following: Figure 4 The second pre-assembly 5 has a roughly L-shaped cross-section that matches the receiving groove 42, and includes a support block 51, a tapering block 52, a protruding tail block 53, a limiting hole 54, an inclined surface 55, and two annular recesses 56. The support block 51 is pivotally connected to the tilting module of the bearing plate unit 3 and extends along the first axis X1. The tapering block 52 extends from the support block 51 along the first axis X1 and tapers, having a trapezoidal cross-section. The protruding tail block 53 extends from the tapering block 52 along the first axis X1, and the radial cross-sectional area of ​​the protruding tail block 53 along the first axis X1 is smaller than the minimum radial cross-sectional area of ​​the tapering block 52 along the first axis X1. The limiting hole 54 is recessed in the protruding tail block 53 in a direction parallel to the second axis X2. The inclined surface 55 is located at a corner of the end of the protruding tail block 53 and is spaced apart from the limiting hole 54, and the extending direction of the inclined surface 55 is oblique to the second axis X2. The annular recesses 56 are respectively located between the bearing block 51 and the tapering block 52, and between the tapering block 52 and the convex tail block 53.

[0048] The operating element 6 is disposed in the through hole 43 and includes a pin 61, a pull rod 62, a baffle 63, and an elastic body 64. The pin 61 has a head 611, an extension 612, a chamfered portion 613, and a screw hole 614. The cross-sectional area of ​​the head 611 is approximately matched with the cross-sectional area of ​​the second hole 432, allowing the head 611 to pass through and move within the second hole 432. The extension 612 extends outward from the head 611, and the cross-sectional area of ​​the extension 612 is smaller than that of the head 611, and is approximately matched with the cross-sectional area of ​​the first hole 431, allowing the extension 612 to pass through and move within the first hole 431. The chamfered portion 613 extends outward from the extension 612 and gradually tapers. The screw hole 614 passes through the head 611 and the extension 612 along the second axis X2.

[0049] The tie rod body 62 has an interconnected end section 621, a body section 622, and a helical section 623. The end section 621 is located outside the through hole 43, and the cross-sectional area of ​​the end section 621 is larger than that of the body section 622. The body section 622 passes through the second hole 432, and the cross-sectional area of ​​the body section 622 is smaller than that of the second hole 432. The helical section 623 is screwed into the threaded hole 614, thereby fixing the pin 61 to the tie rod body 62. The baffle 63 is fixed to the bottom side of the housing 41 and has a through hole 631 extending along the second axis X2. The through hole 631 corresponds to the through hole 43, and the cross-sectional area of ​​the through hole 631 is smaller than the cross-sectional area of ​​the head section 621 and the cross-sectional area of ​​the second hole 432, and roughly matches the cross-sectional area of ​​the body section 622. Therefore, the body section 622 passes through the through hole 631, while the head section 621 cannot pass through the through hole 631 and is located outside the baffle 63. The elastic body 64 is sleeved on the body section 622 and located inside the second hole 432. Its two ends abut against the baffle 63 and the head section 611 respectively, to constantly provide an elastic force. In this embodiment, the elastic body 64 can be a compression spring.

[0050] The surrounding members 7 are respectively disposed in the annular recesses 56 and generally protrude from the surface of the second pre-assembly 5. The surrounding members 7 do not completely fill the annular recesses 56, but leave a certain gap so that during the process of assembling the second pre-assembly 5 into the first pre-assembly 4 (described in detail later), the gap can serve as the space required when the surrounding members 7 are subjected to compression deformation. In this embodiment, the surrounding members 7 are O-rings.

[0051] The following describes the component relationship of the first pre-assembly 4 and the second pre-assembly 5 in terms of their mating connection and mutual removal. The operating element 6 can be positioned along the second axis X2 at a first position ( Figure 4 , Figure 6 , Figure 8 ) and a second position ( Figure 5 , Figure 7 Transform between ) and ). Please refer to Figure 4 The elastic force of the elastic body 64 causes the operating member 6 to tend to remain in the first position. At this time, the head 611 of the pin 61 abuts against the stepped portion 44, the chamfered portion 613 protrudes from the first hole 431 and is partially located in the receiving groove 42, and the head section 621 of the pull rod 62 abuts against the baffle 63.

[0052] As the user gradually inserts the second pre-component 5 into the receiving slot 42 along the first axis X1, the inclined surface 55 first contacts the chamfered portion 613. Since the extending direction of the inclined surface 55 matches the inclination of the chamfered portion 613, the chamfered portion 613 can slide on the inclined surface 55 during the gradual insertion of the second pre-component 5 into the receiving slot 42, until the chamfered portion 613 disengages from the inclined surface 55. During this process, the operating member 6 is pressed by the protruding tail block 53 and gradually changes from the first position to the second position. Figure 5As shown, when the operating member 6 is in the second position, the pin 61 is limited by the protruding tail block 53, the head 611 is away from the stepped part 44, the chamfered part 613 does not protrude from the first hole 431, the head section 621 of the pull rod 62 is away from the baffle 63, the elastic body 64 is compressed by the head 611 and the baffle 63, the elastic force increases, and the limiting hole 54 and the through hole 43 are misaligned and do not correspond to the through hole 43.

[0053] Please see Figure 6 When the second pre-assembly 5 is fully inserted into the receiving slot 42, the limiting hole 54 aligns with the through hole 43. The restoring force of the elastic body 64 causes the operating member 6 to change from the second position to the first position (i.e., elastic reset, and the elastic force of the elastic body 64 decreases). At this time, the chamfered part 613 protrudes from the first hole 431, the pin 61 is partially accommodated in the limiting hole 54, the head 611 abuts against the stepped part 44, and the head section 621 of the pull rod 62 abuts against the baffle 63. Because the operating member 6 is accommodated in the limiting hole 54, the second pre-assembly 5 is limited by the operating member 6 and cannot detach from the first pre-assembly 4. The bearing plate unit 3 and the support frame 1 are interconnected.

[0054] Please see Figure 7 To remove the support plate unit 3 from the support frame 1, the user simply pulls the operating member 6 along the second axis X2, changing the operating member 6 from the first position to the second position. This allows the head 611 to move away from the stepped portion 44, the chamfered portion 613 to disengage from the limiting hole 54 and not protrude from the first hole 431, and the head section 621 of the pull rod 62 to move away from the baffle 63. At this point, the second pre-assembly 5 is no longer limited by the operating member 6, and can be removed from the first pre-assembly 4 along the second axis X2. Figure 8 As shown. After the second pre-component 5 is completely removed from the first pre-component 4, the user releases the operating member 6, and the elastic body 64 rebounds, causing the operating member 6 to change from the second position to the first position.

[0055] Because the first pre-component 4 and the second pre-component 5 often have tolerances during production, during the above-mentioned matching connection and mutual removal process, the second pre-component 5 and the receiving groove 42 are not perfectly matched. The volume of the receiving groove 42 is slightly larger than the volume of the second pre-component 5, resulting in a gap of 0.02mm to 0.18mm between the first pre-component 4 and the second pre-component 5. The surrounding member 7 can compensate for the gap between the first pre-component 4 and the second pre-component 5 through an interference fit to prevent shaking during assembly.

[0056] In summary, the support device of this application does not require additional control components during the process of assembling the second pre-component into the first pre-component. It only needs to utilize the action between the chamfered part and the inclined surface and the elastic body to limit the second pre-component with the operating component when the second pre-component is fully assembled into the first pre-component. The assembly method is simple and convenient, and the relevant quick-release structures are all hidden inside the first pre-component without being excessively exposed, which can improve the overall aesthetics.
