In this invention, the term "several" means two or more.

[0042] In order to solve the problems existing in the prior art, the present invention discloses a support device.

[0043] Figures 1 to 11 , Figures 12 to 16 The specific structures of Embodiments 1 and 2 of the present invention are shown respectively. The specific embodiments of the support device of the present invention will now be described in conjunction with the accompanying drawings.

[0044] See Figure 1 The supporting device includes a first component 1, a second component 2, and a limiting mechanism 3 disposed between the first component 1 and the second component 2. The first component 1 can connect to the supported object, such as a screen light, a webcam / web camera, a speaker, or other electronic device. The first component 1 and the second component 2 can be inserted into each other, and a clamping space is formed between them. The clamping space can clamp the target object, such as a computer screen, thereby supporting the supported object on the target object.

[0045] The limiting mechanism 3 enables the first component 1 and the second component 2 to be in a relatively fixed position.

[0046] See Figure 2 The first component 1 includes a first clamping part 11, a mating part 12, and a connecting part 13.

[0047] The first clamping part 11 is a plate-shaped component, specifically a rectangular plate-shaped component. The first clamping part 11 is fixed to the mating part 12 (see Embodiment 1). Figure 4 The first clamping part 11 and the basket-shaped member 121 in the insertion part 12 are integral structures. (In the description of this invention, the fixed connection includes integral molding.) Furthermore, the plate surface of the first clamping part 11 (it should be understood that the plate surface of the plate-like structure is the surface with the largest area in the plate-like structure) and the insertion direction ( Figure 3 (The direction indicated by the double-headed arrow) is perpendicular.

[0048] See Figure 2 The insertion part 12 can be inserted into the second component 2 to realize the insertion of the first component 1 and the second component 2, thereby forming a clamping space α between the first clamping part 11 and the second clamping part 22 of the second component 2. The clamping space α can realize the clamping of the target object, and the connecting part 13 can connect to the electronic device, thereby realizing the purpose of supporting the electronic device on the target object.

[0049] See Figure 3-4 The insertion part 12 includes a rectangular basket-shaped component 121 and a sealing plate 122 fixedly connected to the opening side of the basket-shaped component 121.

[0050] The insertion part 12 is a hollow rectangular plate formed by the fixed connection of the basket-shaped part 121 and the sealing plate 122, and the plate surface of the first clamping part 11 is perpendicular to the insertion part 12 (the plate surface of this rectangular plate).

[0051] A first clearance hole 1211 is provided at the end of the mating part 12 near the first clamping part 11, and the connecting part 13 is connected to the mating part 12 through the first clearance hole 1211.

[0052] See Figure 3 and Figure 5 The connecting part 13 includes a receiving member 131, a first housing 132, a second housing 133, a first connecting piece 134, a first rotating shaft 135, and a fixing seat 136.

[0053] In embodiment 1, the receiving member 131 is a cylindrical or similar cylindrical structural component. For example, a cylindrical electronic device, such as a screen lamp, can be inserted into the receiving member 131 and then fixedly supported at the target position by the supporting device. In other embodiments, the receiving member 131 can also be a receiving member of other shapes with a receiving space.

[0054] The outer periphery of the accommodating member 131 is fixedly connected to the first housing 132. The first connecting piece 134 is fixedly connected to the first rotating shaft 135 by a pin. The first housing 132 is fixedly connected to the first connecting piece 134 by a pin / hole structure. The second housing 133 is snapped into the first housing 132 by a snap-fit ​​structure and fixed to each other by bolts.

[0055] Two fixing seats 136 are provided. Both ends of the first rotating shaft 135 are fastened to one fixing seat 136. The fixing seat 136 is an "η"-shaped part, including a short piece and a long piece connected to each other through the head. The end of the first rotating shaft 135 is inserted into the head of the fixing seat 136. The bolt passes through the locking hole 1361 to tighten and fix the short piece and the long piece of the fixing seat 136 to the insertion part 12, thereby holding the first rotating shaft 135 located between the short piece and the long piece tightly. The fixing seat 136 is also provided with a fixing hole 1362. The bolt passes through the fixing hole 1362 to fix the fixing seat 136 to the insertion part 12.

[0056] The electronic device is housed within the housing 131. The electronic device, along with the housing 131, the first housing 132, the second housing 133, the first connecting piece 134, and the first rotating shaft 135, is supported on the support device (or target object) by the clamping force of the fixing seat 136 on the first rotating shaft 135. When the position of the electronic device needs to be adjusted, an external force is applied to the housing 131 and transmitted to the first rotating shaft 135 through the first housing 132, the second housing 133, and the first connecting piece 134. When the applied external force exceeds the clamping force of the fixing seat 136 on the first rotating shaft 135, the electronic device, together with the housing 131, the first housing 132, the second housing 133, the first connecting piece 134, and the first rotating shaft 135, rotates in the direction of the external force around the rotation axis determined by the head of the fixing seat. When the electronic device is rotated to the target position, the external force is removed, and the electronic device and connected components are held in the target position by the clamping force of the fixing seat 136.

[0057] The clamping force of the fixing seat 136 on the first rotating shaft 135 can be adjusted by rotating the bolt passing through the locking hole 1361. When the bolt is tightened toward the insertion part 12, the long piece and the short piece move closer together, and the clamping force of the fixing seat 136 on the first rotating shaft 135 increases, and vice versa.

[0058] See Figures 6 to 8 The second component 2 includes an insertion portion 21 and a second clamping portion 22.

[0059] The accommodating insertion portion 21 is a rectangular cylindrical structure with a "hollow square"-shaped cross section, which comprises two pairs of side walls 212 and a first through hole 211 formed in the two pairs of side walls 212. The second clamping portion 22 is a plate-shaped member, and the plate surface thereof is perpendicular to the inserting direction ( Figure 6 the direction indicated by the two-way arrow in [drawings]). In Embodiment 1, it can also be stated that the plate surface of the second clamping portion 22 is perpendicular to the wall surface of the side wall 212. One end of the second clamping portion 22 is fixed to one end of the accommodating insertion portion 21, and in the embodiment, the second clamping portion 22 and the accommodating insertion portion 21 are integrally formed.

[0060] The inserting portion 12 can be inserted from one end of the accommodating insertion portion 21, see Figure 2 , when the inserting portion 12 moves in the first through hole 211, the width a of the clamping space α formed between the first clamping portion 11 and the second clamping portion 22 changes, thereby enabling the supporting device to have various clamping thicknesses.

[0061] Further, when the thickness of a clamped object, such as a screen, is very thin, the second component 2 can be reversed, and the inserting portion 12 is inserted from the other end of the accommodating insertion portion 21 (the end connected to the second clamping portion 22). Since the outer plate surface of the second clamping portion 22 and the end surface of the end of the accommodating insertion portion 21 to which the second clamping portion 22 is fixed are located on the same plane, the clamping height of the clamping space α is changed from the original b2 to b1 plus b2, the clamping area is increased, and clamping is more stable.

[0062] Further, relative movement will occur between the first component 1 and the second component 2 during insertion, which further causes scratching or wear. In order to avoid or reduce scratching and wear, see Figures 6 to 8 , a limiting sleeve 23 is provided in the side wall 212. The limiting sleeve 23 not only avoids or reduces wear, but also limits adjacent components. The outer periphery of the limiting sleeve 23 is matched with the inner wall of the side wall 212, a second through hole 231 matched with the outer periphery of the inserting portion 12 is provided inside the limiting sleeve 23, and when the first component 1 and the second component 2 are inserted, the inserting portion 12 passes through the second through hole 231.

[0063] Specifically: the limiting sleeve 23 is a rectangular sleeve with a "hollow square"-shaped cross section, second avoidance holes 232 are provided on both the left and right sides thereof (that is, the side edges pointed to by the positive direction and the negative direction of the x-axis) for partial structures in the limiting mechanism 3 to pass through, and a positioning structure is provided on the lower side thereof to fix the limiting sleeve relative to the side wall 212, see Figure 7 , the positioning structure comprises a first positioning groove 233 and a second positioning groove 234 provided on the limiting sleeve 23, correspondingly, see Figure 8A first protrusion 2121 and a second protrusion 2122 are provided on the side wall 212. When the limiting sleeve 23 is inserted into the first through hole 211 ( Figure 8 (The arrows indicate the direction of movement of the limiting sleeve 23 when it is inserted into the first through hole 211). The first positioning groove 233 and the first protrusion 2121 first enter the engagement state. The first protrusion 2121 can provide a certain guide for the limiting sleeve 23. Subsequently, the limiting sleeve 23 encounters the second protrusion 2122. The second protrusion 2122 is a protrusion with a guide slope. Under the guidance of the guide slope, the limiting sleeve 23 rises to a certain height (there is a certain height difference between the limiting sleeve 23 and the side wall 212 to allow the limiting sleeve 23 to rise). Then the limiting sleeve 23 descends, and the second positioning groove 234 covers the second protrusion 2122. At this time, the mating end face 21211 of the first protrusion 2121 is exactly in contact with the mating end face 2331 of the first positioning groove 233. Thus, the positioning structure engages and positions the limiting sleeve 23 within the side wall 212.

[0064] See Figure 7 and Figure 9 The limiting sleeve 23 has a plurality of third protrusions 237 inside, the third protrusions 237 protruding toward the second through hole 231, and the third protrusions 237 extending along the mating direction of the first component 1 and the second component 2.

[0065] When the insertion part 12 in the first component 1 is inserted into the receiving part 21 in the second component 2, the outer surface of the insertion part 12 abuts against the third protrusion 237. Optionally, the limiting sleeve 23 is made of plastic.

[0066] Furthermore, see Figure 6 The limiting sleeve 23 is also provided with a first mounting hole 235, and a mounting shaft is provided in the first mounting hole 235. The auxiliary support plate 4 in the support device is rotatably installed through the mounting shaft.

[0067] A receiving groove 221 is formed on the plate surface of the second clamping part 22 away from the receiving part 21. The depth d2 of the receiving groove 221 is equal to the thickness d3 of the auxiliary support piece 4. Therefore, when the auxiliary support piece 4 is received in the receiving groove 221, the plate surface of the auxiliary support piece 4 away from the receiving part 21 and the plate surface of the second clamping part 22 away from the receiving part 21 are on the same plane. In order to keep the auxiliary support piece 4 in a fixed position without shaking when it is in the receiving groove 221, the second clamping part 22 and the auxiliary support piece 4 are provided with matching positioning grooves and positioning protrusions respectively.

[0068] To facilitate the removal of the auxiliary support piece 4 from the receiving groove 221 (in the non-working state), a portion of the receiving groove 221 is made into a through groove. Figure 6 The reference numerals in the accompanying drawings for the receiving groove 221 point to the part of the receiving groove 221 that is made into a through groove, but the depth d2 of the receiving groove 221 mentioned above refers to the thickness of the non-through groove part.

[0069] When the auxiliary support plate 4 is working, it will rotate 180 degrees in the direction indicated by the positive z-axis, and then one of its plates will abut against the side wall 212 of the receiving part 21. This side wall 212 refers to the side wall 212 opposite to the installation position of the auxiliary support plate 4 across the second through hole 231. In order to make the outer surface of the unfolded auxiliary support plate 4 and the outer surface of the second clamping part 22 on the same plane (here, the outer side refers to the side away from the receiving part 21), the side wall 212 abutted by the auxiliary support plate 4 is recessed inward by a certain distance d1 along the insertion direction to avoid displacement. The certain distance d1 is equal to the thickness d3 of the auxiliary support plate 4.

[0070] When the target position is not suitable for fixing by clamping, open the auxiliary support plate 4 and place the support device in a way that is perpendicular to the surface of the second clamping part 22. The second clamping part 22 and the auxiliary support plate 4 together serve as the support plate of the support device to stand the support device on the plane.

[0071] The optimal implementation is when the three data points d1, d2, and d3 mentioned above are equal. Obviously, the three data points can also be different. When the three data points are different, the thickness of the attached anti-slip layer can be changed, or the outer side of the auxiliary support plate 4 after unfolding can be supported in a way that is not in the same plane as the outer side of the second clamping part 22.

[0072] See Figure 10 and Figure 11In embodiment 1, the limiting mechanism 3 includes a button 31, a swing plate 32, a second rotating shaft 33, a torsion spring 34 (corresponding to the first elastic element), and a locking rack 35. The second rotating shaft 33 is a stepped shaft, including at least one step. The middle part of the swing plate 32 is fitted onto the second rotating shaft 33 and rests on the step of the stepped shaft. The upper and lower ends of the second rotating shaft 33 are inserted into the matching second mounting holes 236 on the limiting sleeve 23. One end of the swing plate 32 is abutted against the inner side of the button 31, and the other end is snapped into the groove of the locking rack 35. The torsion spring 34 is sleeved on the second rotating shaft 33, with one end abutting against the inner side of the button 31 and the other end hooked against the outer side of the swing arm of the swing plate 32 near the locking rack 35. The locking rack 35 is fixed to the side of the insertion part 12. The button 31 is provided with multiple grooves. It passes through the second clearance hole 232 provided on the limiting sleeve 23 and the third clearance hole 2123 provided on the side wall 212, and can move in the direction of vertical insertion. In addition, in order to prevent the button 31 from dislodging from the side wall 212 when it moves outward, a step is provided on the side of the button 31 near the side wall 212. The third clearance hole 2123 is smaller than the second clearance hole 232. The stepped part of the button 31 can pass through the second clearance hole 232 but cannot pass through the third clearance hole 2123. That is, when the button 31 moves outward, the step will prevent the button 31 from moving out of the side wall 212.

[0073] In Embodiment 1, the limiting mechanism 3 is disposed on the left and right sides (i.e., the sides in the positive and negative directions of the x-axis) of the insertion part 12. In other embodiments, the limiting mechanism 3 may also be disposed on the upper and lower sides of the insertion part 12.

[0074] In use, the user presses button 31, which moves inward into the support device, pressing the swing plate 32 and one end of the torsion spring 34 located inside button 31. The swing plate 32 rotates around the second pivot 33, and its arm end, which is engaged in the groove of the locking rack 35, rotates outward, leaving the groove and entering the unlocked state. In the unlocked state, the mating part 12 and the second component 2 can move relative to each other (when there is a limiting sleeve 23, the limiting sleeve 23 moves together with the second component 2). The user can apply a force to button 31 along the mating direction while pressing button 31. The limiting sleeve 23 and the second component 2 will move under the action of button 31, thereby changing the size of the clamping space width a. When it moves to a suitable position, the user releases button 31, and the swing plate 32 rotates around the second pivot 33 under the action of the torsion spring 34, causing its arm end to engage in the groove of the locking rack 35, entering the locked state. When locked, the insertion part 12 and the second component 2 cannot move relative to each other.

[0075] In the aforementioned embodiment, the torsion spring 34 can also be configured as a spring. One end of the spring abuts against or is fixedly connected to the inner side of the button 31, and the other end abuts against or is fixedly connected to the outer side of the swing arm of the swing plate 32 near the locking rack 35. When an external force is applied to the button 31, the swing plate 32 rotates and enters the unlocked state. At this time, the spring is compressed. When the external force is released, the swing plate 32 rotates under the elastic force of the spring, and the swing arm near the locking rack 35 re-engages with the locking rack 35, entering the locked state.

[0076] Furthermore, when the limiting sleeve 23 is not provided in the second component 2, the aforementioned limiting mechanism 3 can also be used. It is only necessary to set the second rotating shaft 33 in the limiting mechanism 3 in the first through hole 211 in the receiving part 21.

[0077] To make the working state more stable when the support device is clamped or standing in the target position, an anti-slip layer, such as an adhesive rubber layer, is provided on the surface involved when the support device is clamped or standing. This can also avoid or reduce possible pinching damage to the target position.

[0078] The present invention also discloses Embodiment 2. The main difference between Embodiment 2 and Embodiment 1 lies in the specific implementation of the connecting part 13, the specific setting of the limiting mechanism 3, the absence of the limiting sleeve 23, and some changes caused by the absence of the limiting sleeve 23. The following will mainly introduce the differences between Embodiment 2 and Embodiment 1.

[0079] Note: The same or corresponding technical features in Embodiment 2 and Embodiment 1 use the same reference numerals.

[0080] See Figures 12 to 14 The connecting part 13 includes a receiving member 131, a first housing 132, a second housing 133, a first connecting piece 134, a fixing base 136, a second connecting piece 137, a shaft core 138, and a locking member 139.

[0081] The receiving member 131 is fixedly connected to the second connecting piece 137. The second connecting piece 137, the first connecting piece 134, the first housing 132 and the second housing 133 are fixedly connected to each other. One end of the first connecting piece 134 is tightened onto the shaft core 138 by a locking fastener 139. The shaft core 138 is engaged with the fixing seat 136. The fixing seat 136 is fixed onto the first component 1.

[0082] When the position of the electronic device in the housing 131 needs to be adjusted, an external force presses the housing 131, and the housing 131, as well as the first connecting piece 134, the second connecting piece 137, the first housing 132 and the second housing 133 fixedly connected to the housing 131, all rotate around the outer periphery of the aforementioned shaft 138. When the external force is removed, the housing 131 and the parts fixedly connected to it remain in the target position.

[0083] When the clamping force or tightening force of the first connecting piece 134 needs to be changed, such as when the external electronic equipment changes, the weight changes, or the tightening force required to maintain balance changes, the tightening force of the first connecting piece 134 can be changed by turning the locking fastener 139; optionally, the shaft core 138 is a bolt and the locking fastener 139 is a nut.

[0084] The insertion part 12 also includes a rectangular cross-section basket-shaped member 121 and a sealing plate 122 fixedly connected to the opening side of the basket-shaped member 121. The difference between Embodiment 2 and Embodiment 1 is that the opening side of the basket-shaped member 121 is located on the upper side of the basket-shaped member 121.

[0085] See Figure 13 The limiting mechanism 3 described in Embodiment 2 includes a limiting member 36, a sliding member 37, a second elastic member (not shown), and a locking piece 38.

[0086] The limiting member 36 is fixed to the middle of the basket-shaped member 121 by bolts. A sliding member 37 is slidably provided on both sides of the limiting member 36. The guide plate and / or the frame of the basket-shaped member 121 guides the sliding member 37 to slide. The side of the basket-shaped member 121 is provided with a through hole. One end of the sliding member 37 is close to the limiting member 36, and the other end extends out of the side of the basket-shaped member 121 through the through hole on the side of the basket-shaped member 121.

[0087] The second elastic member is disposed between the sliding member 37 and the limiting member 36. When an external force presses on the sliding member 37, the sliding member 37 moves closer to the limiting member 36, and the second elastic member is compressed. When the external force is removed, the second elastic member gives the sliding member 37 a force to slide in the opposite direction (move away from the limiting member 36). The sliding member 37 is provided with a step to prevent the sliding member 37 from sliding out of the through hole on the side of the basket-shaped member 121.

[0088] The locking piece 38 is attached to the side of the sliding member 37 that extends out of the basket-shaped member 121. The locking piece 38 is a sheet-like part with high friction, such as a rubber pad, and can be attached by adhesive.

[0089] The accommodating insertion portion 21 is a rectangular cylindrical structure with a cross-section in a shape of "hui" (a hollow rectangular shape), wherein the upper side wall is detachably fixed to other side walls, such as Figure 15 shown in.

[0090] Referring to Figure 16 , pressing sheets 214 are fixedly connected to inner wall surfaces of left and right side walls of the accommodating insertion portion 21 via third elastic members (not shown), first guiding sections 2141 are provided at two ends of each pressing sheet 214 along the insertion direction, correspondingly, second guiding sections 371 are provided at two ends of the sliding member 37 protruding from the side wall of the basket-shaped member 121 (see Figure 13 ), the first guiding sections 2141 and the second guiding sections 371 can facilitate the insertion matching portion 12 and the accommodating insertion portion 21 to enter an insertion matching state.

[0091] When it is required to adjust the relative positional relationship between the insertion matching portion 12 and the accommodating insertion portion 21, press the locking sheet 38, the sliding member 37 will move toward the inside of the basket-shaped member 121, the locking sheet 38 is separated from the pressing sheet 214, move the accommodating insertion portion 21 to adjust the position, after the position adjustment is completed, remove the external force, the sliding member 37 moves toward the outside of the basket-shaped member 121 under the action of the second elastic member, so that the locking sheet 38 re-contacts and presses the pressing sheet 214, while the pressing sheet 214 moves outward, it is subjected to a force from the third elastic member that urges it to move inward, after the elastic forces of the second elastic member and the third elastic member reach equilibrium, the pressing sheet 214 and the locking sheet 38 are pressed against each other and keep their positions stable, the insertion matching portion 12 and the accommodating insertion portion 21 are kept at the adjusted position by the friction force between the pressing sheet 214 and the locking sheet 38.

[0092] In Embodiment 2, the limiting sleeve 23 is not provided, correspondingly, the auxiliary support sheet 4 is directly rotatably connected to the second component 2 via a rotating shaft (see Figure 15 ).

[0093] The sliding member 37 can be made of plastic material, so the overall structure is lighter. The sliding member 37 and the pressing sheet 214 are in a mutual extrusion state for a long time, in order to increase the service life of the sliding member 37, a structural member made of metal material can be added inside the sliding member 37 to enhance the strength of the sliding member 37. The pressing sheet 214 can be made of metal material.
