[0026] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0027] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.
[0028] Reference Figures 1-3 In one embodiment, a folding table 100 includes a table top 10 and a scissor lift mechanism 20 connected to the table top. The table top 10 has an upper surface and a lower surface, and the scissor lift mechanism 20 is connected to the lower surface of the table top 10. The scissor lift mechanism 20 is a known and common mechanism that includes a first pair of support assemblies 201 and a second pair of support assemblies 202. The first pair of support assemblies 201 and the second pair of support assemblies 202 have the same configuration and are parallel to each other, and each includes one or more pairs of connecting rods, which are exemplified by two pairs of connecting rods, i.e., the first pair of connecting rods 21 and the second pair of connecting rods 22.
[0029] The first pair of connecting rods 21 and the second pair of connecting rods 22 each have two connecting rods that are rotationally connected to each other and form a longitudinal and transverse intersecting "X" pattern. The bottom ends of the first pair of connecting rods 21 are in contact with a support surface, such as a floor, and the top ends of the first pair of connecting rods 21 are rotationally connected to the bottom ends of the second pair of connecting rods 22, respectively. The top ends of the second pair of connecting rods 22 are close to the lower surface of the table top 10. In one embodiment, for the first pair of support assemblies 201 and the second pair of support assemblies 202, one of the connecting rods in the second pair of connecting rods 22 is rotationally connected to the table top 10. For example, the lower surface of the table top 10 is fixed with a base 23, and one of the connecting rods in the second pair of connecting rods 22 can be connected to the base 23 through a rocker 24, the two ends of the rocker 24 being rotationally connected to the base 23 and the one of the connecting rods in the second pair of connecting rods 22, respectively. It should be noted that in another embodiment, the base 23 and the rocker 24 can be omitted, which will be described in detail later. Through such a configuration, when the top ends of the second pair of connecting rods 22 are moved towards each other under an external force, the second pair of connecting rods 22 are rotated towards each other, thereby driving the first pair of connecting rods 21 to rotate towards each other, so that the overall height of the scissor lift mechanism 20 becomes larger, thereby driving the table top 10 to rise. When the top ends of the second pair of connecting rods 22 are moved in opposite directions under an external force, the second pair of connecting rods 22 are rotated away from each other, thereby driving the first pair of connecting rods 21 to rotate away from each other, so that the overall height of the scissor lift mechanism 20 becomes smaller, thereby driving the table top 10 to descend until the scissor lift mechanism 20 is in a folded state, at which time the folding table 100 has the smallest height, facilitating the user to carry and store it. It should be noted that the working principle of the scissor lift mechanism 20 is described above, and the scissor lift mechanism 20 is a known and common mechanism that can have other possible variations, such as only the first pair of connecting rods 21, the first pair of connecting rods 21 being connected to the table top 10, etc.
[0030] Reference Figures 4-10In one embodiment, the folding table 100 further comprises a locking assembly 30, which is capable of limiting the lowering of the scissor lifting mechanism 20 so as to keep the folding table 100 stable when in use.
[0031] It is to be noted that in some embodiments, the locking assembly 30 is capable of blocking the lowering of the scissor lifting mechanism 20 and also capable of blocking the raising of the scissor lifting mechanism 20, that is, capable of fixing the height of the table board 10, neither raising nor lowering.
[0032] In other embodiments, the locking assembly 30 is only capable of blocking the lowering of the scissor lifting mechanism 20 and does not block the raising of the scissor lifting mechanism 20, so as to keep the folding table 100 stable when in use, and when the height of the folding table needs to be raised, the locking assembly 30 does not need to be unlocked, which can further improve the user experience.
[0033] The locking assembly 30 is located at one end of the scissor lifting mechanism 20 close to the table board. The locking assembly 30 comprises a sliding rod 40 and a pull rod 50. The sliding rod 40 is connected to the scissor lifting mechanism 20, and the sliding rod 40 can move along a first direction relative to the table board 10 along with the scissor lifting mechanism 20. The side surface of the sliding rod 40 is provided with a groove 41. The pull rod 50 is slidably connected to the table board 10, and the pull rod 50 can move along a second direction different from the first direction relative to the table board 10. The pull rod 50 is partially accommodated in the groove 41, for example, the first end 51 of the pull rod 50 is accommodated in the groove 41, so as to prevent the end of the scissor lifting mechanism 20 from moving, thereby limiting the scissor lifting mechanism 20 from driving the table board 10 to lower. Here, the first direction is the direction indicated by the X-axis in Figure 1 the sliding rod 40 can move along the positive direction of the X-axis and the negative direction of the X-axis; and the second direction is the direction indicated by the Y-axis in Figure 1 the pull rod 50 can move along the positive direction of the Y-axis and the negative direction of the Y-axis.
[0034] Through the above structure, by accommodating the first end 51 of the pull rod 50 in the groove 41, the end of the scissor lifting mechanism 20 can be prevented from moving, so as to prevent the height of the scissor lifting mechanism 20 from decreasing, and thus the folding table 100 can be kept stable at a certain height.
[0035] Further, the locking of the scissor lifting mechanism 20 is realized by plugging and unplugging of one pull rod 50, which can save materials, and only one component of the pull rod 50 can reduce the error superposition caused by the connection of multiple components, and the precision of the pull rod 50 inserted into the corresponding through hole 61 and the groove 41 can be improved.
[0036] In one embodiment, the sliding rod 40 is indirectly connected to the end of the scissor lifting mechanism 20. Specifically, the top end 221 of one of the second pair of connecting rods 22 in the first pair of support assemblies 201 and the top end 223 of one of the second pair of connecting rods 22 in the second pair of support assemblies 202 are both connected with the cross rod 25, and the fixed end of the sliding rod 40 is fixed to the cross rod 25. In this way, the cross rod 25 can move along with the aforementioned two top ends 221 and 223 of the second pair of connecting rods 22 in the first pair of support assemblies 201 and the second pair of support assemblies 202, thereby driving the sliding rod 40 to move in the first direction.
[0037] In one embodiment, the lower surface of the table board 10 is provided with two cross rods 26, which are oppositely arranged and each provided with a straight guide groove 261, and the two ends of the cross rod 25 are respectively accommodated in the guide grooves 261. When subjected to the pulling force or pushing force of the aforementioned top ends 221 and 223 of the second pair of connecting rods 22 in the first pair of support assemblies 201 and the second pair of support assemblies 202, the cross rod 25 moves linearly along the first direction under the guidance of the guide grooves 261.
[0038] In one embodiment, the folding table 100 further comprises a guide tube 60 slidably connected with the sliding rod 40, the end of the scissor lifting mechanism 20 comprises a first end and a second end, the sliding rod 40 is connected to the first end, the guide tube 60 is connected to the second end, and the sliding rod 40 is slidably accommodated in the guide tube 60.
[0039] In some embodiments, the guide tube 60 is hollowly arranged, and the guide tube 60 is sleeved on the sliding rod 40, so that the sliding rod 40 can stably slide in the first direction. Optionally, the cross section of the guide tube 60 is substantially rectangular, so that the sliding rod 40 and the guide tube 60 do not relatively rotate.
[0040] According to the foregoing description, the first end refers to the top ends 221 and 223 of the second pair of connecting rods 22 in the first pair of support assemblies 201 and the second pair of support assemblies 202. The second end refers to the top ends 222 and 224 of the other second pair of connecting rods 22 in the first pair of support assemblies 201 and the second pair of support assemblies 202. Among them, the top ends 221 and 222 belong to the second pair of connecting rods 22 in the first pair of support assemblies 201, and the top ends 223 and 224 belong to the second pair of connecting rods 22 in the second pair of support assemblies 202.
[0041] It is noted that the first end of the scissor lifting mechanism 20 is not limited to the aforementioned case. Since the first pair of support assemblies 201 and the second pair of support assemblies 202 of the scissor lifting mechanism 20 each include a plurality of pairs of connecting rods, the first end can be other positions. For example, in other embodiments, the first end of the scissor lifting mechanism 20 can be the bottom end of one of the second pair of connecting rods 22 in the first pair of support assemblies 201 and the bottom end of one of the second pair of connecting rods 22 in the second pair of support assemblies 202. In yet another embodiment, the first end of the scissor lifting mechanism 20 can be a position near the bottom end of one of the first pair of connecting rods 21 in the first pair of support assemblies 201 and a position near the bottom end of one of the first pair of connecting rods 21 in the second pair of support assemblies 202.
[0042] In one embodiment, the guide tube 60 is indirectly connected to the second end. Specifically, the top ends 222 and 224 are each connected to the cross rod 27, and the fixed end of the guide tube 60 is fixed to the cross rod 27. In this way, the cross rod 27 can move along with the aforementioned top ends 222 and 224 connected thereto, thereby driving the guide tube 60 to move in the first direction.
[0043] In one embodiment, the lower surface of the table top 10 is provided with two cross rod guides 28 that are oppositely arranged and each provided with a straight guide slot 281, and the two ends of the cross rod 27 are respectively received in the guide slots 281. When subjected to the pulling force or pushing force of the aforementioned top ends 222 and 224, the cross rod 27 moves linearly along the first direction under the guidance of the guide slots 281.
[0044] It is noted that the aforementioned base 23 and rocker 24 can enable the cross rods 25 and 27 to move at the same speed. For example, when the lengths of the guide slots 261 of the guide 26 and the guide slots 281 of the guide 28 are arranged to be the same, when the end of the cross rod 25 slides from one end to the other end of the guide slot 261, the cross rod 27 is synchronized to slide from one end to the other end of the guide slot 281. Understandably, in one embodiment, the base 23 and the rocker 24 can be omitted, and at this time, the cross rods 25 and 27 are limited and guided by the guide slots 261 and 281, which can achieve the connection of the scissor lifting mechanism 20 to the table top 10 and the guiding of the cross rods 25 and 27 to move towards or away from each other.
[0045] The free end of the slide rod 40 extends into the interior of the guide tube 60 from the open end of the guide tube 60. In one embodiment, the pull rod 50 is indirectly and slidingly connected to the table top 10. Specifically, the pull rod 50 is connected to the guide tube 60, which can move along the first direction with the guide tube 60 and can move along the second direction relative to the guide tube 60. In this embodiment, since the pull rod 50 is in the form of an elongated rod, in order to ensure that the pull rod 50 does not shake when it moves along the first direction with the guide tube 60, the lower surface of the table top 10 is further provided with a guide 501, which is provided with a guide groove 502, the extension direction of the guide groove 502 is parallel to the first direction, and the pull rod 50 passes through the guide groove 502. The guide groove 502 is used to provide support and guidance to the pull rod 50, so that the pull rod 50 does not become a cantilever structure, and can stably and smoothly move along the first direction.
[0046] It can be understood that in another embodiment, the pull rod 50 can be directly connected to the table top 10 and can only slide along the second direction. At this time, the guide tube 60 needs to be provided with a straight groove to allow the first end of the pull rod 50 to pass through the straight groove and be located inside the guide tube 60, and allow the guide tube 60 to move along the first direction relative to the pull rod 50. Those skilled in the art who understand the spirit of the present application will understand this embodiment, which will not be described in detail here. It should be noted that in another embodiment, the pull rod 50 can be directly connected to the table top 10 and can only slide along the second direction, and the guide tube 60 is omitted. In this way, when the slide rod 40 sliding along the first direction under the drive of the scissor lifting mechanism 20 slides to the preset position, the first end 51 of the pull rod 50 is opposite to the groove 41 of the slide rod 40, so that the first end 51 can be inserted into the groove 41.
[0047] It can be understood that when the guide tube 60 is omitted, the first end of the scissor lifting mechanism 20 is also not limited to being arranged near one end of the table top 10, that is, the slide rod 40 is not limited to being arranged near one end of the scissor lifting mechanism 20 close to the table top 10.
[0048] For example, the first end of the scissors lifting mechanism 20 is located at the bottom end of one of the second pair of connecting rods 22 in the aforementioned first pair of support assemblies 201. At this time, the pull rod 50 can be connected with the table board 10, and the pull rod 50 is configured to be movable relative to the table board 10 along the Z-axis direction and the second direction, so that the pull rod 50 can be inserted into the corresponding groove 41 and achieve limiting. Alternatively, for example, a guide sleeve is arranged on the table board 10, and the pull rod 50 is connected with the table board 10 through the guide sleeve and is movable relative to the table board 10 along the second direction and the Z-axis direction. Specifically, the guide sleeve has a through slot, the through slot of the guide sleeve penetrates through the guide sleeve along the second direction and has a length direction along the Z-axis, and the pull rod 50 is arranged in the through slot of the guide sleeve, so that the pull rod 50 can be movable relative to the table board 10 along the Z-axis direction and the second direction.
[0049] Further, the pull rod 50 in the above scheme can also not be connected with the table board 10, for example, a through slot is arranged at the second pair of connecting rods 22, and the pull rod 50 is arranged to be inclined relative to the first direction, the second direction and the Z-axis direction, so that the pull rod 50 can be arranged in the through slot of the second pair of connecting rods 22 and the groove 41, thereby achieving limiting.
[0050] In one embodiment, the guide tube 60 is provided with a through hole 61, the first end 51 of the pull rod 50 passes through the through hole 61 of the guide tube 60 and is located inside the guide tube 60 and accommodated in the groove 41 of the sliding rod 40, so as to block the guide tube 60 and the sliding rod 40 from moving away from each other.
[0051] In one embodiment, the pull rod 50 is connected to the guide tube 60 through a fixing member 70. The fixing member 70 is fixed to the guide tube 60, the pull rod 50 is arranged in the fixing member 70 and inserted into the groove 45. The fixing member 70 includes a body 71 and a receiving portion 72, the body 71 is a hollow tubular structure which is sleeved and fixed to the guide tube 60. The receiving portion 72 protrudes from the side of the body 71 and is provided with a receiving cavity 721, the body 71 is provided with a through hole 711 which is communicated with the receiving cavity 721, and the first end 51 of the pull rod 50 passes through the receiving cavity 721, the through hole 711 of the body 71 and the through hole 61 of the guide tube 60 and is located inside the guide tube 60.
[0052] In one embodiment, the locking assembly 30 further includes an elastic element 80, which is received in the receiving cavity 721 of the fixing member 70. The elastic element 80 may be a cylindrical helical spring, which applies a pushing force to the pull rod 50 so that the first end 51 of the pull rod 50 is held in the groove 41 of the sliding rod 40. Specifically, the locking assembly 30 also includes an elastic element abutment portion 52 and an end cap 73. The elastic element abutment portion 52 protrudes from the side of the pull rod 50 and is located in the receiving cavity 721 of the receiving portion 72. For example, the elastic element abutment portion 52 is a retaining spring, and the side of the pull rod 50 is provided with an annular groove 53 in which the retaining spring is engaged. The end cap 73 is fixed to the receiving portion 72 and covers the opening end of its receiving cavity 721. The end cap 73 is provided with a through hole that allows the pull rod 50 to pass through, so that the first end 51 of the pull rod 50 can pass through the end cap 73, the receiving cavity 721 of the receiving part 72, the through hole 711 of the body 71 and the through hole 61 of the guide tube 60 and be located inside the guide tube 60.
[0053] The two ends of the elastic member 80 abut against the elastic member contact portion 52 and the end cap 73 respectively, and are in a compressed state. Thus, the elastic member 80 applies a pushing force to the elastic member contact portion 52, causing the elastic member contact portion 52 to press tightly against the bottom of the receiving cavity 721 of the receiving portion 72. At this time, the first end of the pull rod 50 is held in the groove 41 of the sliding rod 40 and will not easily disengage from the groove 41.
[0054] In one embodiment, the pull rod 50 is located below the tabletop 10, for example, near the lower surface of the tabletop 10. A handle 54 is connected to the second end of the pull rod 50 opposite the first end 51. The handle 54 is located within the area defined by the edge of the tabletop 10; for example, the handle 54 may be flush with one edge of the tabletop 10. With this configuration, in Figure 1 In the indicated usage state, when the user needs to fold the folding table 100, they can easily grasp the handle 54 and then apply a pushing force to the pull rod 50 via the handle 54. This pushing force overcomes the force exerted on the pull rod 50 by the elastic element 80, causing the first end 51 of the pull rod 50 to disengage from the groove 41 of the sliding rod 40. At this time, the movement of the top ends of the second pair of connecting rods 22 of the scissor-type lifting mechanism 20 is no longer restricted, allowing the user to adjust the height of the scissor-type lifting mechanism 20.
[0055] In one embodiment, the sliding rod 40 may be provided with a plurality of grooves 41 arranged along its length, so that the first end 51 of the pull rod 50 can be received in the grooves 41 at different positions, so that the folding table 100 is kept at different heights, thereby enabling the folding table 100 to more widely adapt to the needs of different users.
[0056] In one embodiment, each groove 41 comprises a bottom surface 411 and a slanted surface 412 extending from the bottom surface 411 to the side surface of the sliding rod 40 in a direction away from the guide tube 60. With such a configuration, each groove 41 has only its closed end capable of abutting the first end 51 of the pull rod 50, while the slanted surface 412 does not block the first end 51. Thus, when the sliding rod 40 and the guide tube 60 move towards each other, the first end 51 of the pull rod 50 moves towards the slanted surface 412, and when the first end 51 comes into contact with the slanted surface 412, a pushing force in the second direction is generated on the pull rod 50, causing the pull rod 50 to be pushed outwards, with the first end 51 sliding on the slanted surface 412 until it is completely out of the groove 41. When the sliding rod 40 and the guide tube 60 try to move away from each other under the operation of the user, the first end 51 of the pull rod 50 tries to move towards the closed end of the groove 41, and since the first end 51 abuts the closed end of the groove 41, the sliding rod 40 cannot move relative to the guide tube 60. That is, the abutment of the first end 51 of the pull rod 50 with the closed end of the groove 41 blocks the guide tube 60 and the sliding rod 40 from moving away from each other.
[0057] When the first end 51 of the pull rod 50 is located in the rightmost groove 41 among the three grooves 41 in Figure 5 , if the user wants to lower the height of the folding table 100 or fold it, the user first needs to hold the handle 54 and pull it outwards until the first end 51 of the pull rod 50 is out of the groove 41. At this time, the relative movement between the sliding rod 40 and the guide tube 60 is no longer restricted, and under the action of the gravity of the table top 10 or the pressure applied by the user, the sliding rod 40 and the guide tube 60 move in directions away from each other. It should be noted that after the sliding rod 40 and the guide tube 60 move a small distance relative to each other, the user can release the handle 54, and the first end 51 of the pull rod 50 comes into contact with the side surface of the sliding rod 40 under the pushing of the elastic member 80. In the subsequent process, the first end 51 slides relative to the side surface of the sliding rod 40 until it moves to the groove 41 adjacent to the aforementioned groove 41, i.e., the middle groove 41 among the three grooves 41 in Figure 5 . If the user is still not satisfied with the height of the folding table 100 at this time, he or she can repeat the above operation until the first end 51 slides relative to the side surface of the sliding rod 40 to the leftmost groove 41 among the three grooves 41 in Figure 5 . Through the above operation, the user can adjust the height of the folding table 100 and switch the folding table 100 to the completely folded state.
[0058] When the first end 51 of the pull rod 50 is located in the rightmost groove 41 among the three grooves 41 in Figure 5If the user wants to increase the height of the folding table 100, he can use his foot to press against the bottom end of the first pair of connecting rods 21 of the locking assembly 30 which is in contact with the supporting surface (e.g. the floor), and use his hand to grab the edge of the table top 10 and pull it upwards in the vertical upward direction. In order to facilitate the user's operation, a crossbar 29 is connected between the first pair of connecting rods 21 of the first pair of supporting assemblies 201 and the first pair of connecting rods 21 of the second pair of supporting assemblies 202, so that the user can step on one crossbar 29 when performing the operation.
[0059] After the above-mentioned operation, although the first end 51 of the pull rod 50 is in contact with the closed end of the groove 41, this does not hinder the relative movement between the sliding rod 40 and the guide tube 60. That is, the above-mentioned operation of the user will cause the sliding rod 40 and the guide tube 60 to move towards each other, the first end 51 slides towards the inclined surface 412 of the groove 41, and will slide along the inclined surface 412. After moving out of the groove 41, the first end 51 continues to move towards the adjacent groove 41 until it moves into the groove 41 (i.e. Figure 5 the middle groove 41 of the three grooves 41). If the user is still not satisfied with the height at this time, he can continue to pull the table top upwards, which will cause the first end 51 to move into the rightmost groove 41 of the three grooves 41. Through the above-mentioned operation, the user can adjust the folding table 100 to the desired height. Figure 5
