[0023] The present invention will be further described below with reference to specific embodiments.

[0024] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0028] like Figure 1-6As shown, a multi-directional adjustable seat armrest includes an armrest body 1, a connecting ball 2, and a fixing seat 3. The connecting ball 2 is connected to the lower part of the armrest body 1 and is rotatably disposed in the fixing seat 3. Several spring pins 2.1 are connected to the connecting ball 2, and several locking grooves 3.1 are provided on the fixing seat 3 for disengaging the spring pins 2.1. By rotatably connecting the connecting ball 2 to the fixing seat 3, the connecting ball 2 can rotate freely at multiple angles, allowing the armrest body 1 connected to it to have a wider adjustment range to meet the diverse needs of users. Simultaneously, the spring pins 2.1 engage with the locking grooves 3.1 to facilitate user adjustment and fixation of the position and angle of the armrest body 1, enhancing user convenience.

[0029] Preferably, the armrest body 1 includes a top shell 1.1 and a bottom shell 1.2 that are mutually connected. A slider 1.3 is slidably connected to the side of the bottom shell 1.2 near the top shell 1.1. A limiting pin 2.2 is provided on the connecting ball 2 to circumferentially limit the slider 1.3. The limiting pin 2.2 passes through the bottom shell 1.2 and engages with a limiting groove 1.3.1 provided on the slider 1.3, thereby connecting the armrest body 1 and the connecting ball 2. This allows the top shell 1.1 and the bottom shell 1.2 of the armrest body 1 to slide relative to the connecting ball 2, facilitating the user to adjust the front and rear position of the armrest body 1 for user convenience. Preferably, the limiting pin 2.2 can be configured as a cross shape, rectangle, quincunx shape, etc.

[0030] Preferably, the bottom shell 1.2 is provided with a limiting hole 1.2.1 for the limiting pin 2.2 to pass through, and the limiting pin 2.2 is slidably connected in the limiting hole 1.2.1. By providing the limiting hole 1.2.1, the limiting pin 2.2 can pass through the limiting hole 1.2.1 and cooperate with the limiting groove 1.3.1; by providing the limiting pin 2.2 to be slidably connected in the limiting hole 1.2.1, the bottom shell 1.2 can slide relative to the connecting ball 2.

[0031] Preferably, a shielding plate 2.3 is fitted onto the connecting ball 2 to cover the limiting hole 1.2.1, and the shielding plate 2.3 is disposed close to the lower part of the bottom shell 1.2. By providing the shielding plate 2.3, not only is the limiting hole 1.2.1 covered, making the appearance of the present invention more aesthetically pleasing, but it also prevents foreign objects from getting stuck in the limiting hole 1.2.1 and affecting the sliding of the bottom shell 1.2.

[0032] Preferably, the slider 1.3 is provided with a bolt hole 1.3.2 at the bottom of the limiting groove 1.3.1. A connecting bolt 1.4 is inserted into the bolt hole 1.3.2 from the side of the slider 1.3 away from the connecting ball 2 and is connected to the limiting pin 2.2, thereby fixing the slider 1.3 and the connecting ball 2.

[0033] Preferably, the fixed base 3 includes an upper base 3.2 and a lower base 3.3 that fit together, and the upper base 3.2 and the lower base 3.3 surround and form a rotating cavity 3.4 for accommodating the connecting ball 2.

[0034] Preferably, the upper seat 3.2 has a connecting hole 3.2.1 for the connecting ball 2 to extend and connect to the armrest body 1. For example, the limiting pin 2.2 can extend from the connecting hole 3.2.1, allowing the connecting ball 2 to connect to the bottom shell 1.2 via the limiting pin 2.2. Preferably, the size of the connecting hole 3.2.1 should be larger than that of the limiting pin 2.2 to prevent the connecting hole 3.2.1 from jamming the limiting pin 2.2 and preventing the connecting ball 2 from rotating.

[0035] Preferably, each of the spring pins 2.1 is equally spaced on the connecting ball 2 to ensure that the connecting ball 2 is subjected to uniform force, and each of the locking grooves 3.1 is equally spaced on the fixing seat 3 to facilitate the user to judge and adjust the angle at which the connecting ball 2 is fixed.

[0036] Preferably, a connecting groove 3.5 is provided between adjacent locking grooves 3.1 to facilitate the user sliding the spring pin 2.1 between adjacent locking grooves 3.1, preventing the user from not being able to find the position of the locking groove 3.1. Preferably, the bottom of the connecting groove 3.5 should be higher than the bottom of the locking groove 3.1.

[0037] Preferably, the end of the spring pin 2.1 protrudes from the surface of the connecting ball 2, the end of the spring pin 2.1 is configured as a hemispherical surface, the bottom surface of the locking groove 3.1 is configured as a hemispherical surface that mates with the end of the spring pin 2.1, and the connecting groove 3.5 is configured as an arc-shaped surface that mates with the end of the spring pin 2.1, so that the user can slide the end 2.1.1 of the spring pin 2.1 into or out of each locking groove 3.1.

[0038] The method of using this invention is as follows: by moving the armrest body 1, the connecting ball 2 is driven to rotate in the fixed seat 3. When the spring pin 2.1 on the connecting ball 2 is aligned with the locking groove 3.1, the spring pin 2.1 pops out and locks into the locking groove 3.1 to fix the position of the armrest body 1. The front and rear position of the armrest body 1 can also be adjusted by pulling the top shell 1.1 and the bottom shell 1.2.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
