[0025] The present invention provides an auto-deploying tripod, suitable for supporting devices such as, but not limited to, mobile phones, cameras, video cameras or projectors.

[0026] 1 to 4, in one embodiment of the present invention, the tripod includes a pull rod assembly 11, a mounting bush 12, a plurality of support legs 13, a fixed seat 14, a plurality of connecting rods 15, a sleeve assembly 16, and a locking and unlocking mechanism 17. A first stopper 111 is provided on the outer circumferential wall of the pull rod assembly 11. The mounting bush 12 is slidably fitted to the pull rod assembly 11. One ends of the plurality of support legs 13 are rotatably mounted on the mounting bush 12. The fixed seat 14 is attached to the bottom of the pull rod assembly 11 and is provided with a second stopper 141. A plurality of connecting rods 15 correspond to the support legs 13 one-to-one. One ends of the connecting rods 15 are rotatably mounted on the support legs 13, and the other ends of the connecting rods 15 are rotatably mounted on the fixed seat 14. The sleeve assembly 16 includes a protective sleeve 161, a first slide bush 162, a second slide bush 163, and a spring. The pull rod assembly 11 includes a spring 164, and the first and second sliding bushes 162 and 163 are slidably mounted on the pull rod assembly 11. The elastic member 164 is mounted on the pull rod assembly 11 and is located between the first and second sliding bushes 162 and 163. The protective sleeve 161 is mounted on the elastic member 164, and one end of the protective sleeve 161 is connected to the second sliding bush 163 and the other end of the protective sleeve 161 is connected to the mounting bush 12. The locking and unlocking mechanism 17 is provided at the bottom of the pull rod assembly 11. The locking and unlocking mechanism 17 is used to lock the other ends of the plurality of support legs 13 to maintain them in the closed position and to unlock the other ends of the plurality of support legs 13 to automatically deploy them to the open position. In the closed position, the first sliding bush 162 abuts against the first blocking portion 111, and in the open position, the second sliding bush 163 abuts against the second blocking portion 141.

[0027] In this embodiment, the number of the support legs 13 is at least three, and is not limited thereto.

[0028] The outer peripheral wall of the pull rod assembly 11 may be provided with sliding grooves for the mounting bush 12 and sleeve assembly 16 to slide, and correspondingly, the inner peripheral walls of the mounting bush 12, first slide bush 162 and second slide bush 163 may be provided with sliding ribs to facilitate sliding, thereby improving the smoothness with which the support legs 13 automatically deploy.

[0029] The elastic member 164 can be selected as a metal or plastic spring, an elastic expansion sleeve, etc., and is preferably a compression spring, but is not limited thereto.

[0030] In order to deploy each support leg 13 at an appropriate angle to ensure stability of support, in this embodiment, the first blocking portion 111 may be a plurality of protrusions protruding from the outer wall of the pull rod assembly 11.

[0031] Similarly, second blocking portion 141 may be a plurality of bosses protruding from fixed seat 14. To facilitate assembly and fully utilize each boss, a plurality of mounting holes are provided in the outer peripheral wall of pull rod assembly 11, and the plurality of bosses are engaged in a one-to-one correspondence with the plurality of mounting holes so as to secure fixed seat 14 to the bottom of pull rod assembly 11.

[0032] When in use, simply manually operate the locking and unlocking mechanism 17 to unlock the other end of the support leg 13, separate the support leg 13 from the locking and unlocking mechanism 17, and automatically deploy it to the open position under the action of the elastic member 164, thereby realizing the function of automatically deploying the support leg 13 with one touch, and it can be seen that this effectively improves ease of use.

[0033] In addition, a protective sleeve 161 is fitted around the outer periphery of the elastic member 164, which covers the elastic member 164 and avoids a decrease in safety and aesthetics due to the elastic member 164 being exposed. Furthermore, both ends of the protective sleeve 161 are connected to the second sliding bush 163 and the mounting bush 12, respectively, which enables the sleeve assembly 16 and the mounting bush 12 to be linked together. When the support leg 13 is unlocked, the elastic member 164 returns from its compressed state to its original state, driving the second sliding bush 163 to slide the mounting bush 12 downward, and further deploying the support leg 13 to the open position.

[0034] In order to improve the convenience and reliability of the assembly between the protective sleeve 161 and the mounting bush 12, in one embodiment, as mainly shown in FIG. 2, the end of the protective sleeve 161 connected to the mounting bush 12 may be provided with a plurality of connecting lugs 1611, each of which is provided with a connecting hole 161a, and the mounting bush 12 is provided with a matching truncated cone at a position corresponding to the connecting hole 161a, which is engaged in the connecting hole 161a to secure the mounting bush 12 and one end of the protective sleeve 161.

[0035] In this embodiment, a connecting hole 161a may be provided in the body of the protective sleeve 161 below the connecting lug 1611, and a matching truncated cone may be provided at the corresponding position of the mounting bush 12, further improving the reliability of the connection between the two components.

[0036] Furthermore, as shown in FIG. 2, in order to easily connect the protective sleeve 161 and the second slide bush 163, a connection hole 161a may be provided at the end of the protective sleeve 161 connected to the second slide bush 163, and the second slide bush 163 may be provided with a truncated cone, thereby improving the convenience and reliability of the connection between the two components.

[0037] To further improve the convenience of operation, in one embodiment, as shown in Figures 2 and 4, the locking and unlocking mechanism 17 may include a key 171, a key fixing seat 172, and a spring, a connecting post is provided on the key fixing seat 172, and the connecting post and the fixing seat 14 are connected and fixed by a screw, the key 171 is provided in the key fixing seat 172 so as to be depressible, and the spring is fitted to the connecting post and abuts against the key 171.

[0038] In use, the user simply presses the key 171 to unlock each support leg 13, separating the end of the support leg 13 from the locking and unlocking mechanism 17, after which each support leg 13 automatically unfolds to the open position under the action of the elastic member 164.

[0039] In this embodiment, a locking protrusion is provided at each end of the multiple support legs 13, and a locking hole that engages with and matches the locking protrusion is provided in the key 171, and in the closed position, the locking protrusion is engaged within the locking hole.

[0040] Of course, a locking hole may be provided at one end of support leg 13, and key 171 may be provided with a matching locking protrusion that is engaged with the locking hole. Any structure is acceptable as long as the end of support leg 13 can be locked to the bottom of pull rod assembly 11, and the two can be separated after being pressed to unlock.

[0041] Furthermore, as shown in FIG. 4, the locking and unlocking mechanism 17 may further include a decorative member 173, which is attached to the key 171 and has an anti-slip pattern, thereby increasing the friction resistance and making it easier for the user to press the key 171.

[0042] In some embodiments, a connecting seat 18 may be provided on the top of the pull rod assembly 11, and a connecting screw may be attached to the connecting seat 18, and a standard screw such as 1 / 4 or 3 / 8 may be selected to attach external photographic equipment such as a camera.

[0043] In addition, in order to accommodate the support needs of more application scenarios, in some embodiments, the pull rod assembly 11 may include two or more stages of pull rods connected in series, thereby making it easier for users to adjust the support height.

[0044] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural modifications made using the contents of the specification and drawings of the present invention without departing from the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are all included in the patent protection scope of the present invention.
