For those of ordinarily skilled in the art, the specific meanings of the terms described above in the present invention may be interpreted according to specific circumstances. As shown in FIGs. 1-12, an embodiment of the present invention provides a folding chair frame having a side table, including a main body 1 and a side table 3; the main body 1 includes a base frame 11 and a main support frame, the base frame 11 is connected to the main support frame, and both the base frame and the main support frame are foldable to reduce a storage volume; correspondingly, a connecting member 2 is connected to the base frame 11, and the side table 3 is rotatably connected to the connecting member 2, such that the side table 3 has a use state and a folded state, and the side table is switchable between the two states by rotation. Specifically, when the side table 3 is in the use state, the side table 3 is positioned on an outer side of the base frame 11 and is in a horizontal direction, with a table surface facing upward, such that cups, electronic devices, or other items can be placed on the table surface; when the side table 3 is in the folded state, the main body 1 has two states, that is, a using state or a folded state. After the main body 1 and the side table 3 are fully folded together, the side table 3 is received in a receiving space enclosed by the folded base frame 11, which does not increase a thickness, a width and a volume of the chair frame after folding, thereby without increasing a storage space, and allowing for a greater quantity of the chair frames to be transported. Moreover, since the side table 3 is hidden within the folded base frame 11, the side table 3 is protected from damage during transportation, thereby ensuring the quality of the side table 3. When the main body 1 is in use, the side table 3 is positioned within the unfolded base frame 11, avoiding occupying an unfolded space and affecting the activities of other personnel. Specifically, as shown in FIGs. 2-3, the connecting member 2 may take various structural forms, as long as it can enables the side table 3 to rotate from the outer side of the base frame 11 to an inner side of the base frame 11. The folding and rotation of the side table 3 are performed when the base frame 11 is in an unfolded state. After the side table 3 is rotated to the inner side of the base frame 11, and the base frame 11 and the main support frame are folded together, the side table 3 is hidden in the folded chair frame. Specifically, in this embodiment, the connecting member 2 includes a connecting piece 21, a rotatable block 22, and a connecting rod 23; one end of the connecting piece 21 is mounted on the base frame 11, the other end of the connecting piece is a free end, and the free end of the connecting piece 21 is located within the receiving space enclosed by the folded base frame 11. In fact, except that the entire connecting piece 21 is mounted at an end portion of the base frame 11, other components of the connecting piece are received in the receiving space enclosed by the folded base frame 11, so as to avoid increasing the thickness of the folded chair frame. Correspondingly, a sliding hole 221 is formed on the rotatable block 22, an axis of the sliding hole 221 is perpendicular to a side surface of the base frame 11, one end of the connecting rod 23 is slidably and rotatably disposed in the sliding hole 221, and the other end of the connecting rod is connected to the side table 3, such that the side table 3 can slide and rotate along the axis of the sliding hole 221. Since the side table 3 is in a horizontal state and is mounted on the base frame 11 when in use, the side table 3 is specially made to be capable of sliding along the sliding hole 221, to enable the side table 3 to rotate smoothly, such that the side table 3 moves in a direction perpendicular to the side surface of the base frame 11 and away from the base frame 11, and the side table 3 is no longer mounted on the base frame 11. Correspondingly, a limiting plate 25 is arranged at an end of the connecting rod 23, the limiting plate 25 is positioned on an outer side of the sliding hole 221, an outer diameter of the limiting plate 25 is greater than an aperture of the sliding hole 221, so as to prevent the end of the connecting rod 23 from disengaging from the sliding hole 221 when the side table 3 moves in the direction perpendicular to the side surface of the base frame 11 and away from the base frame 11; the side table 3 can then rotate about the axis of the sliding hole 221 from a horizontal direction to a vertical direction, and finally rotate to the vertical direction, or to a midway inclined direction, as long as the side table 3 can be rotated to an inner side of the base frame 11 at the position. Moreover, the rotatable block 22 is rotatably mounted at the free end of the connecting piece 21, and the side table 3 after rotation can be rotated again together with the rotatable block 22, such that the side table 3 is rotated from the outer side of the base frame 11 to the inner side thereof, thereby realizing the switching between the use state and the folded state. A diagram of the folding process of the side table 3 can refer to FIGs. 4-6. Specifically, when the folding chair frame is folded, the existence of the connecting piece 21 may obstruct the connecting rod 23 from further approaching. Therefore, a clearance groove 24 is formed on the connecting piece 21, allowing the obstructed connecting rod 23 to move further into the clearance groove 24 and reach an original folded position, avoiding an increase in the folded thickness of the folding chair frame when the connecting rod 23 therein is obstructed by the connecting piece 21. In addition, an end of the connecting rod 23 connected to the side table 3 is a II-shaped structure and is connected by bolts, such that the support of the side table 3 is more stable. In this embodiment, an axis of the rotatable block 22 is vertically oriented. When the side table 3 is rotated to the inner side of the base frame 11, even if a position of the side table 3 is slightly offset, the folding process of the base frame 11 together with the main support frame will force the side table 3 into the receiving space enclosed by the folded base frame 11, without increasing an overall folded volume of the folding chair frame. Specifically, at least one holding recess 31 is formed on a table top of the side table 3, a plurality of the holding recesses 31 may be formed in different shapes. Specifically, the holding recess 31 may be cylindrical, rectangular, or square, and may be designed according to actual needs of the users for holding items such as teacups, electronic products, or food. Specifically, the side table 3 is provided with a placement hole 32, an access slot is formed on a side wall of the side table 3, and the access slot is in communication with the placement hole 32. In this embodiment, the placement hole 32 includes tapered holes and cylindrical holes arranged from top to bottom, the access slot is in communication with both the tapered holes and the cylindrical holes and is configured to hold stemware, and stems of the stemware can be inserted through the access slot and extend into the placement hole 32 for stable placement. Specifically, as shown in FIG. 1, the base frame 11 and the main support frame have various forms of folding structure. In this embodiment, the base frame 11 includes a front frame 111 and a rear frame 112, a linkage assembly is connected between middle portions of the front frame 111 and the rear frame 112. The linkage assembly includes a first rotating piece and a second rotating member, and the second rotating member includes two second rotating pieces. The main support frame includes a backrest support 12, a leg support 13, a seat frame 14, and two armrest supports 15. The front frame 111, the rear frame 112, the backrest support 12, the leg support 13, and the seat frame 14 are all U-shaped structures, with specific connection relationships as follows: two upper ends of the front frame 111 and the rear frame 112 are rotatably connected to the two armrest supports 15; two lower ends of the backrest support 12 are rotatably connected to two rear end portions of the seat frame 14 respectively, an upper end of the backrest support 12 is a free end, and two lower portions of the backrest support 12 are connected to rear end portions of the armrest supports respectively 15; two upper ends of the leg support 13 are respectively rotatably connected to two front end portions of the armrest supports 15, a lower end of the leg support 13 is a free end, and two upper portions of the leg support 13 are connected to two front end portions of the seat frame respectively 14; one end of each of the two second rotating pieces is respectively located on opposite sides of a support rod inside the rear frame 112 and is rotatably connected by a pin shaft, the other ends thereof are connected by a connecting shaft to form an integral unit, and are rotatably connected to a support rod inside the seat frame 14 and one end of the first rotating piece by pin shafts, and the other end of the first rotating piece is rotatably connected to a support rod inside the front frame 111, such that a folding angle of the base frame 11 can be limited via the linkage assembly, and the seat frame 14 is supported to make the main body 1 more stable and have better load-bearing capacity after fully unfolding. Preferably, the connecting shaft is provided with a mounting groove that engages with the support rod inside the rear frame 112. After being unfolded, the support rod inside the rear frame 112 is positioned inside the mounting groove. As shown in FIG. 1, in the unfolded state, the mounting groove on the connecting shaft between the second rotating pieces is mounted in cooperation with the support rod inside the rear frame 112. When being folded as a whole, as shown in FIGs. 7-8, the side table 3 is first folded to the outer side of the base frame 11, bottom portions of the front frame 111 and the rear frame 112 move toward each other, the second rotating pieces rotate in a direction away from the rear frame 112, the rear end portions of the seat frame 14 are driven to rotate in a direction near the rear frame 112, the free end of the backrest support 12 rotates in a direction near an upper end surface of the seat frame 14, and the leg support 13 rotates in a direction near a lower end surface of the seat frame 14, ultimately folding together. Specifically, in this embodiment, based on a structure of the base frame 11, a mounting end of the connecting piece 21 is mounted at the middle portion of the rear frame 112, and a support groove 33 that engages with the front frame 111 is formed on an end of the side table 3 away from the rear frame 112. When the side table 3 is rotated to the horizontal state, the support groove 33 is located above the front frame 111, and the support rod inside the front frame 111 is positioned inside the support groove 33 to support the side table 3. When the side table 3 needs to be folded, the side table 3 is first rotated upward and then moved outward along the sliding hole 221, such that the support rod inside the front frame 111 is disengaged from the support groove 33, and the side table 3 can then be rotated downward to complete the folding process. Specifically, in this embodiment, as shown in FIGs. 9-12, the armrest support 15 includes an armrest 151, a sliding rod 152, and a locking assembly; front end and rear end of the armrest 151 are rotatably connected to a lower portion of the backrest support 12 and an upper end of the leg support 13, respectively, and the sliding rod 152 is disposed inside the armrest 151 to support the armrest 151; the locking assembly includes a sliding block 153 and a locking member, a slotted hole (not shown in the figures) is formed on the sliding block 153, the sliding block 153 is sleeved over the sliding rod 152 through the slotted hole, the sliding block 153 is capable of sliding in a length direction of the sliding rod 152. The two upper ends of the front frame 111 and the rear frame 112 are rotatably connected to the sliding block 153 to support the armrest support 15, and locking member is configured to lock the sliding rod 152. Specifically, when the locking assembly is locked, the sliding block 153 is prevented from sliding relative to the sliding rod 152, thereby preventing the sliding rod 152 from rotating, and angles of the backrest support 12 and the leg support 13 cannot be adjusted. When the locking assembly is released, the sliding block 153 is allowed to slide relative to the sliding rod 152, the sliding rod 152 rotates, and the backrest support 12 and the leg support 13 can be adjusted in angle. After the angle is adjusted, the locking member can be used for locking. Specifically, in order to achieve locking, in this embodiment, the locking member includes a locking block 154, a locking housing 155, and an elastic member. The locking housing 155 is disposed on the sliding block 153, the locking block 154 is disposed on the locking housing 155, a locking portion is disposed on an upper end portion of the locking housing 155 and is located above the sliding rod 152, and the elastic member is disposed between an upper side wall of the locking housing 155 and an upper end portion of the sliding block 153; Through the cooperation of the locking block 154 and a lower side wall of the sliding block 153, the locking block 154 abuts against the lower side wall of the sliding block 153, such that the entire locking block 154 moves downward, the locking portion is driven to move downward, and finally tightly abut against an upper side wall of the sliding rod 152. Moreover, the elastic member provides preload force, and the sliding block 153 is driven by locking block 154 to move upward, and under the action of the elastic member, the locking block 154 is pressed against the lower side wall of the sliding block 153, an inner side wall of the sliding block 153 is pressed against a lower side wall of the sliding rod 152, and upper and lower side walls of the sliding rod 152 are locked at the same time, improving the locking effects. Correspondingly, when the locking needs to be released, it is sufficient to make the locking block 154 to move in an opposite direction, such that the locking block 154 no longer abuts against the lower side wall of the sliding block 153, and the inner side wall of the sliding block 153 also disengages from the lower side wall of the sliding rod 152. Moreover, under the action of the elastic member, the locking portion moves upward and no longer engages with the upper side wall of the sliding rod 152, thus returning to the initial state. Specifically, in order to achieve locking of the sliding rod 152 by the locking member, in this embodiment, the locking housing 155 is sleeved around an outer periphery of the sliding block 153, such that the locking block 154 is located directly below the sliding rod 152. Correspondingly, a notch communicating with the slotted hole in the sliding block is formed on an upper end of the sliding block 153. When the locking member is required to lock the sliding rod 152, the locking portion can descend through the notch into the slotted hole and engage with the upper side wall of the sliding rod 152; one end of the locking block 154 is provided with an eccentric wheel 157, the locking block is rotatably disposed on the locking housing 155, and the other end of the locking block is a free end. A rotational axis of the locking block 154 is located below the lower side wall of the sliding block 153, and a distance between the rotational axis of the locking block 154 and the lower side wall of the sliding block 153 is less than a maximum radius of the eccentric wheel 157. When a free end of the locking block 154 drives the eccentric wheel 157 to rotate, an outer side wall of the eccentric wheel 157 will first come into contact with the lower side wall of the sliding block 153. As the eccentric wheel 157 continues to rotate, the sliding block 153 is forced to move upward until the inner side wall of the sliding block 153 comes into contact with the lower side wall of the sliding rod 152, the sliding block 153 will stop moving, the locking housing 155 moves downward at the same time, the locking portion is driven to move downward until the outer side wall of the eccentric wheel 157 at its maximum radius comes into contact with the lower side wall of the sliding block 153, at which the locking housing 155 stops moving downward. At this moment, the locking portion abuts against the upper side wall of the sliding rod 152, the elastic member between the upper end portion of the locking housing 155 and an upper side wall of the sliding block 153 has the preload force, the preload force causes the locking housing 155 to have an upward movement tendency, such that the eccentric wheel 157 continuously abuts against the lower side wall of the sliding block 153, and the sliding block 153 can continuously abuts against the lower side wall of the sliding rod 152 to complete the abutment and locking of both the upper and lower side walls of the sliding rod 152. Specifically, the elastic member includes two spring pieces 156. One end of each of the spring pieces 156 is connected to the outer side wall of the upper end portion of the locking housing 155, and the other end thereof is in contact with the upper side wall of the sliding block 153. Each spring piece 156 has a certain elasticity. When the locking housing 155 is driven to move downward by the locking block 154, the upper end of the locking housing 155 also moves downward, and lower ends of the spring pieces 156 abut against the upper side wall of the sliding block 153. Since the spring pieces 156 and the outer side wall of the upper end of the locking housing 155 form an acute angle, the spring pieces 156 are bent and generate elastic force, which applies an upward force to the locking housing 155, causing the locking block 154 to abut against the lower side wall of the sliding block 153. In this embodiment, the spring piece is a plastic sheet, which has a certain degree of elasticity. The two plastic sheets are integrally formed with the locking housing 155, and are all made of plastic. Specifically, in this embodiment, the locking portion includes latching teeth 158, and a plurality of latching slots 1521 that engage with the latching teeth 158 are arranged on the upper side wall of the sliding rod 152 in a length direction. When the locking housing 155 moves downward, the latching teeth 158 engage into the corresponding latching slots 1521, the latching teeth 158 abut against inner slot wall of the latching slots 1521 to form a locking structure, thereby preventing the sliding block 153 from sliding relative to the sliding rod 152. Consequently, the sliding rod 152 is prevented from moving back and forth, and the backrest support 12 and the leg support 13 cannot be adjusted. The plurality of latching slots 1521 are formed on the upper side wall of the sliding rod 152 to form a rack-like structure, which is less expensive than mounting a separate rack onto the upper side wall of the sliding rod 152. In this embodiment, based on the structure of the above locking assembly, when the entire chair frame is folded, the sliding block 153 can slide relative to the sliding rod 152 toward a connection point between the armrests 151 and the leg support 13, such that connection potions between the upper end portion of the base frame 11 and the armrest support 15 coincide with connection points between the armrests 151 and the leg support 13. After the chair frame is folded, the upper end portion of the base frame 11 is located at the front end portions of the armrests 151, and the rear end portion of the base frame 11 is located at the rear end portion of the seat frame 14, thereby further reducing an overall volume of the folded chair frame. As shown in FIG. 13, this embodiment discloses a folding chair, including a chair fabric 4 and a folding chair frame described in any of the foregoing embodiments, where the chair fabric 4 is mounted onto a use surface formed by upper surfaces of the backrest support 12, the seat frame 14, and the leg support 13. The above embodiments are merely preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention, and any non-substantial variations and substitutions made by those skilled in the art on the basis of the present invention shall fall within the scope of protection claimed by the present invention.
