Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0046] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0047] In one embodiment, please refer to Figure 1 The support frame assembly includes a base 1 and a support frame 2. The support frame 2 is swingably configured on the base 1. The support frame 2 has a stowed position and an open position in its swing stroke. Please refer to Figure 1 and Figure 6 The base 1 has a stowed position stopper 11 and an open position stopper 12. When the support frame 2 is in the stowed position, the stowed position stopper 11 contacts the support frame 2 to prevent the support frame 2 from continuing to swing in the stowed direction. Figure 8 When the support frame 2 is in the open position, the open position stopper 12 contacts the support frame 2 to prevent the support frame 2 from continuing to swing in the opening direction.

[0048] Please refer to Figures 5 to 8The support frame assembly further includes an elastic arm 3 disposed on the base 1. When the support frame 2 is in the stowed position, the elastic arm 3 contacts the support frame 2 to prevent the support frame 2 from swinging in the opening direction. When the support frame 2 is in the open position, the elastic arm 3 contacts the support frame 2 to prevent the support frame 2 from swinging in the stowed direction. When the support frame 2 swings between the open position and the stowed position, the elastic arm 3 generates elastic deformation, so that the support frame 2 needs to overcome the elastic force of the elastic arm 3 when it moves from the stowed position to the opening direction and from the open position to the stowed direction.

[0049] When the support frame 2 is in the stowed position, the stowed position stopper 11 on the base 1 contacts with the support frame 2 to prevent the support frame 2 from continuing to swing in the stowed direction, and the elastic arm 3 contacts with the support frame 2 when the support frame 2 is in the stowed position to prevent the support frame 2 from swinging in the opening direction. When the support frame 2 leaves the stowed position, the elastic arm 3 needs to be elastically deformed to overcome the elastic force of the elastic arm 3, so that the support frame 2 is more stable when in the stowed position.

[0050] Similarly, when the support frame 2 is in the open position, the open position stopper 12 on the base 1 contacts the support frame 2 to prevent the support frame 2 from continuing to swing in the opening direction, and the elastic arm 3 contacts the support frame 2 when the support frame 2 is in the open position to prevent the support frame 2 from swinging in the folding direction. When the support frame 2 leaves the open position, the elastic arm 3 needs to be elastically deformed to overcome the elastic force of the elastic arm 3, so that the support frame 2 is more stable when in the open position.

[0051] Further, in one embodiment, please refer to Figures 6 to 8 , when the support frame 2 is in the retracted position, the elastic arm 3 contacts the support frame 2 and applies an elastic force to the support frame 2 to make the support frame 2 swing in the retracted direction. When the support frame 2 is in the open position, the elastic arm 3 contacts the support frame 2 and applies an elastic force to the support frame 2 to make the support frame 2 swing in the open direction. The position of the support frame 2 is maintained by the elastic force of the elastic arm 3, which can make the support frame 2 more stable. In some other embodiments, in addition to using the elastic force of the elastic arm 3 to maintain the position of the support frame 2, other methods can also be used. For example, when the support frame 2 is in the open position, the elastic arm 3 can also contact the support frame 2 without deformation, and no elastic force is applied to the support frame 2. Similarly, when the support frame 2 is in the retracted position, the elastic arm 3 can also contact the support frame 2 without deformation, and no elastic force is applied to the support frame 2.

[0052] In some other embodiments, the elastic arm 3 may also contact the support frame 2 when the support frame 2 is in the stowed position and apply an elastic force to the support frame 2 to make the support frame 2 swing in the stowed direction, and not contact the support frame 2 when the support frame 2 is in the open position. Of course, in some other embodiments, the elastic arm 3 may not contact the support frame 2 when the support frame 2 is in the stowed position, and contact the support frame 2 when the support frame 2 is in the open position and apply an elastic force to the support frame 2 to make the support frame 2 swing in the open direction.

[0053] Further, in one embodiment, please refer to Figure 7 , the swing stroke of the support frame 2 has a balanced position. At the balanced position, the elastic force of the elastic arm 3 on the support frame 2 exceeds the swing axis of the support frame 2. In this way, when the support frame 2 swings between the balanced position and the open position, the elastic arm 3 applies an elastic force to the support frame 2 to swing the support frame 2 in the opening direction, and when the support frame 2 swings between the balanced position and the stowed position, the elastic arm 3 applies an elastic force to the support frame 2 to swing the support frame 2 in the stowed direction. This makes the support frame 2 have a better feel in place during operation.

[0054] Specifically, in one embodiment, please refer to Figure 5 and Figure 6 One end of the elastic arm 3 is fixed on the base 1, and the other end is a free end 31 for contacting the support frame 2. The free end 31 of the elastic arm 3 is more easily deformed, and can exert a greater elastic force on the support frame 2. In some other embodiments, the elastic arm 3 can also have both ends fixed, and the middle is used to contact the support frame 2.

[0055] In one embodiment, please refer to Figure 5 and Figure 6 The elastic arm 3 is V-shaped as a whole, and includes a connecting section 32 and a contact section 33. The contact section 33 is used to contact the support frame 2, and the connecting section 32 is fixedly connected to the base 1. One end of the contact section 33 is a free end 31, and the other end is a fixed end 331, and the fixed end 331 is connected to the connecting section 32. When the support frame 2 is in the open position, the free end 31 contacts the support frame 2 and applies an elastic force to the support frame 2 to keep the support frame 2 in the open position. When the support frame 2 is in the retracted position, the free end 31 contacts the support frame 2 and applies an elastic force to the support frame 2 to keep the support frame 2 in the retracted position.

[0056] In one embodiment, please refer to Figure 4 and Figure 6The support frame 2 includes an elastic arm contact portion 21, a swing mounting portion 22 and a leg 23. The swing mounting portion 22 is used to be swingably mounted on the base 1, and the elastic arm contact portion 21 is used to contact the elastic arm 3. In the length direction of the leg 23, the swing mounting portion 22 is located between the elastic arm contact portion 21 and the leg 23. The leg 23 and the elastic arm contact portion 21 are located on both sides of the swing mounting portion 22, so there is more space and it is more convenient to install.

[0057] Specifically, in one embodiment, please refer to Figure 4 and Figure 6 , the swing mounting portion 22 is a swing shaft 220, and the elastic arm contact portion 21 is a protrusion 210 on the swing shaft 220. For ease of operation, in one embodiment, please refer to Figure 4 The protrusion 210 has an elastic arm contact surface 211, and the elastic arm contact surface 211 is a smooth contact. The support frame 2 contacts the elastic arm 3 through the smooth curved surface on the protrusion 210, so that the support frame 2 moves more smoothly, is not easy to get stuck, and is not easy to be scratched. Specifically, in one embodiment, please refer to Figure 4 and Figure 6 The protrusion 210 has a first protrusion end and a second protrusion end, and the arrangement direction of the first protrusion end and the second protrusion end is perpendicular to the extension direction of the swing shaft 220. The first protrusion end is connected to the swing shaft 220, and the second protrusion end is in contact with the elastic arm 3, and the elastic arm contact surface 211 is at the fixed end 331. Specifically, in one embodiment, please refer to Figure 4 and Figure 6 The elastic arm contact surface 211 is an arc surface, and the elastic arm contact surface 211 and other side surfaces of the protrusion 210 are smoothly transitioned.

[0058] In one embodiment, please refer to Figure 4 and Figure 6 , the protrusion 210 is integrally formed with the swing shaft 220. In some other embodiments, the protrusion 210 can be connected to the swing shaft 220 by welding, bonding or fastening. In one embodiment, the swing shaft 220 extends left and right, and the size of the protrusion 210 in the left and right direction is smaller than the size of the swing shaft 220 in the left and right direction, so as to facilitate the installation of the swing shaft 220.

[0059] In one embodiment, please refer to Figure 2 and Figure 3 The base 1 has a base hole 13 for the legs 23 to pass through, please refer to Figure 6The base 1 has an exposed side 14 and a hidden side 15. The exposed side 14 is exposed when in use. The hidden side 15 is opposite to the exposed side 14. The swing mounting portion 22 and the elastic arm contact portion 21 are located on the hidden side 15. In this way, after the support frame 2 is opened, the swing mounting portion 22 and the elastic arm 3 are not easily seen, the exposed side 14 is more concise, and the swing mounting portion 22 and the elastic arm contact portion 21 are not easily bumped. In some other embodiments, the support frame 2 can also be completely installed on the exposed side 14.

[0060] Further, in one embodiment, please refer to Figure 2 and Figure 7 , the exposed side 14 has a support frame groove 18. When the support frame 2 is in the retracted position, the part of the leg 23 on the exposed side 14 is received in the support frame groove 18. By storing the support frame 2 in the support frame groove 18, the support frame 2 is not easily bumped or misoperated after being retracted, and the overall appearance is more beautiful. In some other embodiments, the support frame 2 can also protrude from the exposed side 14 of the base 1 when in the retracted position.

[0061] In one embodiment, please refer to Figure 2 and Figure 6 The stowed position stopper 11 is the bottom of the support frame slot 18, and the leg 23 is received in the support frame slot 18 and is stopped by the bottom of the support frame slot 18, so as to limit the leg 23 from swinging further. In some other embodiments, the stowed position stopper 11 may also be in other positions, such as the stowed position stopper 11 may also be in the hidden side 15 of the base 1, such as stopping the swing mounting portion 22 or the elastic arm contact portion 21.

[0062] In one embodiment, please refer to Figure 2 and Figure 7 The axis of the swing shaft 220 extends left and right. In the left and right directions, the support frame groove 18 is located in the middle position of the base 1, and the support frame groove 18 is symmetrical left and right.

[0063] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 6 The base 1 includes a base body 16 and a fixing seat 17 fixed on the base body 16, the base hole 13 is on the base body 16, the fixing seat 17 is on the hidden side 15, the legs 23 extend from the hidden side 15 through the base hole 13 to the exposed side 14, and the swing mounting portion 22 is clamped between the base body 16 and the fixing seat 17. The fixing seat 17 blocks a part of the base hole 13. By blocking a part of the base hole 13 by the fixing seat 17, the structure of the hidden side 15 can be reduced and avoided from being exposed.

[0064] Specifically, in one embodiment, please refer to Figure 6The fixing seat 17 is fixedly mounted on the hidden side 15 of the seat body 16, and the fixing seat 17 and the seat body 16 are fixed by screws 4, so that it is convenient to clamp the swing mounting portion 22. In some other embodiments, the fixing seat 17 can also be fixed to the seat body 16 by any other feasible method, such as bonding, welding or clamping.

[0065] In one embodiment, please refer to Figure 5 , the elastic arm 3 is integrally formed with the fixing seat 17. In some other embodiments, the elastic arm 3 can be fixedly installed with the fixing seat 17 by means of screws 4, or can be fixed on the fixing seat 17 by means of bonding or welding.

[0066] Specifically, in one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The fixing seat 17 has a fixing seat groove 171, and the seat body 16 has a seat body groove 161. The fixing seat groove 171 and the seat body groove 161 clamp the swing shaft 220. Please refer to Figure 5 There are two fixing seat grooves 171 , and the two fixing seat grooves 171 are respectively used to clamp the two ends of the swing shaft 220 .

[0067] In one embodiment, please refer to Figure 4 and Figure 6 The leg 23 includes a curved section 231, and the curved section 231 is surrounded by an avoidance groove 232. The avoidance groove 232 is used to avoid the hole wall of the base hole 13 when the support frame 2 is in the open position, and the open position stopper 12 is used to stop with the groove wall of the avoidance groove 232. In this way, when the support frame 2 is in the open position, the curved section 231 fills part of the space of the base hole 13 in a contoured manner, and the internal structure of the hidden side 15 will not be exposed due to the opening of the support frame 2, so that the function of the support frame 2 is increased while maintaining the integrity of the appearance. In one embodiment, the open position stopper 12 is on the base body 16, and the open position stopper 12 is located at the position of the base hole 13.

[0068] In one embodiment, please refer to Figure 4 and Figure 6 The curved section 231 includes a straight section 2311 and an arc section 2322, and the center of the circle corresponding to the arc section 2322 is located on the central axis of the swing shaft 220. When the support frame 2 moves to the open position, the arc surface of the arc section 2322 in the avoidance groove moves along the hole wall of the base hole and does not interfere with the hole wall of the base hole.

[0069] In one embodiment, please refer to Figures 5 to 8The fixing seat 17 has a fixing seat hole 172, and the fixing seat hole 172 is connected with the base hole 13. The fixing seat hole 172 avoids the curved section 231 and the protrusion 210, and one end of the elastic arm 3 is connected to the hole wall of the fixing seat hole 172. When the support frame 2 is in the open position, the curved section 231 is on the side of the fixing seat 17 facing the seat body 16, and when the support frame 2 is in the retracted position, the curved section 231 extends from the fixing seat hole 172 to the hidden side 15 of the base 1.

[0070] In one embodiment, please refer to Figure 5 and Figure 6 The fixing seat 17 includes a boss 173, and the boss 173 extends along the fixing seat hole 172 in a semi-enclosed shape. The top surface of the boss 173 is flush with the bottom surface of the support frame slot 18, and the boss 173 blocks a part of the base hole 13. After the boss 173 blocks the base hole 13, the top surface of the boss 173 is flush with the bottom surface of the support frame slot 18. The bottom surface of the support frame slot 18 is the surface that blocks the support frame 2 when the support frame 2 is in the retracted position.

[0071] In one embodiment, the present application can achieve a clear sense of being in place by cleverly designing the swing shaft 220, the bump 210 and the elastic arm 3 structure of the support frame 2. The support frame 2 can be opened and closed within a certain angle range, and the support frame 2 will not shake when it is in the open position and the retracted position. When opening and retracting the support frame 2, the open and closed positions have a clear sense of being in place and a limit, and can automatically be in place after crossing the equilibrium position, and the structure is compact, the number of parts is small, and the cost is low.

[0072] In one embodiment, please refer to Figures 1 to 10 , the assembly method of the support frame assembly is:

[0073] Pass the support frame 2 through the base hole 13 from the hidden side 15 of the base 1, then place the swing shaft 220 in the base groove 161, and then fix the fixed seat 17 and the base 16 with screws 4, so that the base 16 and the fixed seat 17 clamp the swing shaft 220 and allow the swing shaft 220 to swing relative to the base 16.

[0074] In one embodiment, the opening and closing process of the support frame 2 is as follows:

[0075] Please refer to Figure 6 and Fig. 9When the support frame 2 is in the stowed position, the stowed position stopper 11 on the base 1 contacts the support frame 2 to prevent the support frame 2 from continuing to swing in the stowed direction, and the elastic arm 3 contacts the support frame 2 and applies elastic force to the support frame 2 when the support frame 2 is in the stowed position to prevent the support frame 2 from swinging in the opening direction. When the support frame 2 needs to be operated to leave the stowed position, the support leg 23 is operated to rotate the swing shaft 220 relative to the base 16. At this time, the protrusion 210 contacts the elastic arm 3 to further deform the elastic arm 3. The operating force on the support leg 23 overcomes the elastic force of the elastic arm 3 until the support frame 2 swings to the balanced position. Please refer to Figure 7 The elastic force of the elastic arm 3 on the support frame 2 passes through the swing axis of the swing shaft 220, and the elastic deformation of the elastic arm 3 reaches the maximum value. After the support frame 2 continues to swing toward the open position, the elastic force of the elastic arm 3 on the support frame 2 drives the support frame 2 to swing toward the open position. At this time, there is no need to operate the support frame 2. The support frame 2 can automatically move to the open position under the action of the elastic force of the elastic arm 3.

[0076] Similarly, please refer to Figure 8 and Fig.10 When the support frame 2 is in the open position, the open position stopper 12 on the base 1 contacts the support frame 2 to prevent the support frame 2 from continuing to swing in the open direction, and the elastic arm 3 contacts the support frame 2 and applies elastic force to the support frame 2 to prevent the support frame 2 from swinging in the retracted direction. When the support frame 2 needs to be operated to leave the open position, the support leg 23 is operated to rotate the swing shaft 220 relative to the base 16. At this time, the protrusion 210 contacts the elastic arm 3 to further deform the elastic arm 3. The operating force on the support leg 23 overcomes the elastic force of the elastic arm 3 until the support frame 2 swings to the equilibrium position. The elastic force of the elastic arm 3 on the support frame 2 exceeds the swing axis of the swing shaft 220, and the elastic deformation of the elastic arm 3 reaches the maximum value. After the support frame 2 continues to swing to the retracted position, the elastic force of the elastic arm 3 on the support frame 2 drives the support frame 2 to swing to the retracted position. At this time, there is no need to operate the support frame 2. The support frame 2 can automatically move to the retracted position under the elastic force of the elastic arm 3.
