[0002] Considering the current market situation and public demand for sports equipment, there is an urgent need to add a foldable table function to sports equipment, especially treadmills. The aim is to meet the needs of diverse users, allowing them to place laptops or tablets on the table while working and exercising, achieving fitness results while completing their tasks. Additionally, some customers only use the table occasionally, making the folding function particularly important. However, existing foldable table technologies suitable for sports equipment are limited, failing to meet the demand for simultaneous running and working, while also providing convenient storage. Utility Model Content

[0003] The purpose of this utility model is to provide a foldable tabletop to address the problem that there are very few foldable tabletops suitable for sports equipment in the existing technology, which cannot meet people's needs for working while running, while also satisfying the need for easy storage. The specific technical solution is as follows:

[0004] One aspect of this utility model provides a foldable tabletop, including a tabletop, a base, an upper connecting rod, and a lower connecting rod. The first end of the lower connecting rod is rotatably connected to the base, and the second end is rotatably connected to the first side of the tabletop. The first end of the upper connecting rod is rotatably connected to the middle area of ​​the lower connecting rod, and the second end is slidably connected to the other side of the tabletop. When the tabletop is unfolded, the second end of the upper connecting rod slides towards the second end of the lower connecting rod, while simultaneously driving the lower connecting rod to rotate outward around the base until the upper connecting rod reaches its first limit position. When the tabletop is folded, the second end of the upper connecting rod slides away from the second end of the lower connecting rod, while simultaneously driving the lower connecting rod to rotate inward around the base until the upper connecting rod reaches its second limit position.

[0005] Furthermore, a first limiting structure is provided on the base, which abuts against the upper connecting rod to limit the movement trajectory of the upper connecting rod.

[0006] Furthermore, the base includes a support seat, the first end of which is rotatably connected to the first end of the lower connecting rod, and the second end is provided with a first limiting shaft. The second end of the support seat is positioned closer to the unfolded tabletop than the first end, and the first limiting shaft acts as a first limiting structure and abuts against the upper connecting rod.

[0007] Furthermore, a second limiting shaft is also provided on the support base. The first end of the second limiting shaft near the support base is located on the rotation path of the first end of the lower connecting rod. The end of the first end of the lower connecting rod is also provided with a limiting groove. When the table is unfolded, the limiting groove of the lower connecting rod abuts against the second limiting shaft.

[0008] Furthermore, the base also includes a connecting part, which is located near the first end of the support base. The connecting part connects the support base to a preset column and makes the support part protrude from the column.

[0009] Furthermore, a tabletop support is provided on the tabletop, one end of which has a sliding groove, and the second end of the upper connecting rod is connected to the sliding groove. The other end of the tabletop support has a bracket hole for the lower connecting rod to rotate and connect, and the second end of the lower connecting rod is rotatably connected to the bracket hole.

[0010] Furthermore, the tabletop support includes two support side plates spaced apart from each other, the support base includes two support side plates spaced apart from each other, and the upper connecting rod and the lower connecting rod are both located between the two support side plates and the two support side plates.

[0011] Furthermore, the side of the tabletop support is also provided with a support groove for accommodating the support base. After the tabletop is folded, part or all of the support base is embedded in the support groove.

[0012] Furthermore, the tabletop is also equipped with slots for inserting products into which they are to be used.

[0013] Another aspect of this utility model provides a treadmill, including the foldable tabletop described above.

[0014] This utility model discloses a foldable tabletop. The first end of the lower connecting rod is rotatably connected to the base, and the second end is rotatably connected to the first side of the tabletop. The first end of the upper connecting rod is rotatably connected to the middle area of ​​the lower connecting rod, and the second end is slidably connected to the other side of the tabletop. When the tabletop is unfolded, the second end of the upper connecting rod slides closer to the second end of the lower connecting rod, simultaneously causing the lower connecting rod to rotate outwards around the base until the upper connecting rod reaches its first limit position. At this point, the upper and lower connecting rods and the tabletop form a stable triangular structure, providing stable support for the tabletop. When the tabletop is folded, the second end of the upper connecting rod slides away from the second end of the lower connecting rod, simultaneously causing the lower connecting rod to rotate inwards around the base until the upper connecting rod reaches its second limit position. At this point, both the upper and lower connecting rods are close to the tabletop, reducing the overall volume of the structure. This utility model employs a clever structural design to integrate the tabletop function into fitness equipment, resulting in a simple, stable, reliable, and high-strength structure.

[0020] Figure 6 This is a structural diagram of a support base according to an embodiment of the present invention. Detailed Implementation

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] like Figure 1 - Figure 6 As shown, the foldable tabletop provided in this embodiment of the present invention includes a tabletop 1, a base 6, an upper connecting rod 3, and a lower connecting rod 5. The first end of the lower connecting rod 5 is rotatably connected to the base 6, and the second end is rotatably connected to one side of the tabletop 1. The first end of the upper connecting rod 3 is rotatably connected to the middle region of the lower connecting rod 5, and the second end is slidably connected to the other side of the tabletop 1. When the tabletop 1 is unfolded, the second end of the upper connecting rod 3 slides towards the second end of the lower connecting rod 5, simultaneously causing the lower connecting rod 5 to rotate outward around the base 6 until the upper connecting rod 3 reaches its first limit position. When the tabletop 1 is folded, the second end of the upper connecting rod 3 slides away from the second end of the lower connecting rod 5, simultaneously causing the lower connecting rod 5 to rotate inward around the base 6 until the upper connecting rod 3 reaches its second limit position. (Refer to...) Figures 1-3 The first extreme position is the position closest to the second end of the lower link 5, and the second extreme position is the position furthest from the second end of the lower link 5.

[0023] As shown in the attached diagram, in this embodiment of the invention, the tabletop 1, upper connecting rod 3, and lower connecting rod 5 form a structure similar to a crank-slider. The upper connecting rod 3 slides back and forth on one side of the tabletop 1. When the upper connecting rod 3 moves to its first extreme position, a triangular structure is formed between the upper connecting rod 3, the lower connecting rod 5, and the tabletop 1. At this point, the tabletop 1 is in an unfolded state, and based on the stable triangular structure, the upper connecting rod 3 and the lower connecting rod 5 can stably support the tabletop 1. Conversely, when the upper connecting rod 3 moves to its second extreme position, the upper connecting rod 3 and the lower connecting rod 5 can move closer to the tabletop 1. At this point, the upper connecting rod 3 and the lower connecting rod 5 tend to be on the same straight line and close to the back of the tabletop 1, and the tabletop 1 is in a closed state. This structure cleverly borrows from the crank-slider structure to achieve smooth opening and closing of the tabletop 1, and the structure is simple and reliable.

[0024] Meanwhile, in this embodiment of the invention, the first end of the lower connecting rod 5 is rotatably connected to the base 6, and the first end of the upper connecting rod 3 is connected to the middle area of ​​the lower connecting rod 5. When the upper connecting rod 3 is pulled, the angle between the upper connecting rod 3 and the lower connecting rod 5 gradually opens so that it can support the tabletop 1. At the same time, the rotation of the lower connecting rod 5 around the base 6 drives the entire tabletop 1 to rotate upward until the tabletop 1 rotates to a horizontal state, thus completing the opening of the tabletop 1. Similarly, when the tabletop 1 is pushed backward and downward, the angle between the upper connecting rod 3 and the lower connecting rod 5 gradually decreases, and the lower connecting rod 5 also rotates backward and downward at the same time, thus completing the folding of the tabletop 1. In this embodiment of the invention, the tabletop 1 unfolds and folds smoothly, making it easy to operate. Accordingly, in this embodiment of the utility model, one end of the lower connecting rod 5 is rotatably connected to the base 6, and the other end is rotatably connected to the table 1. This allows the rotation radius of one side of the table 1 to be the length of the entire lower connecting rod 5. A larger rotation radius is more suitable for the environment of fitness equipment such as treadmills. When the table 1 is folded, it can be folded to the outside of the treadmill. When the table 1 is unfolded, it can rotate a larger range. At this time, the table 1 is raised to the upper side of the treadmill column 7 and extends into the front side of the treadmill, making it convenient for users to use the table 1 during exercise.

[0025] Furthermore, in one embodiment of this utility model, the length relationship between the upper connecting rod 3 and the lower connecting rod 5 is not limited. In a preferred embodiment of this utility model, the length of the upper connecting rod 3 is greater than the length of the lower connecting rod 5. When the upper connecting rod 3, the lower connecting rod 5, and the table 1 form a triangle for supporting the table 1, the length of the side containing the upper connecting rod 3 is greater than the length of the side containing the lower connecting rod 5, and the included angle between the upper connecting rod 3 and the table 1 is smaller than the included angle between the lower connecting rod 5 and the table 1. This allows most of the table 1 to extend into the front of the base 6, and thus into the front of the treadmill, facilitating user operation.

[0026] Furthermore, in this embodiment of the invention, a first limiting structure is also provided on the base 6. The first limiting structure abuts against the upper connecting rod 3 to limit the movement trajectory of the upper connecting rod 3. The first limiting structure not only allows the upper connecting rod 3 to move along the set trajectory, but also provides support for the tabletop 1 when it is unfolded, making the tabletop 1 more stable. In this embodiment of the invention, the first limiting structure is a support structure protruding from the column, specifically in the form of a support block connected to the column 7, or a support shaft connected to the column 7, etc.

[0027] Furthermore, referring to Figures 5-6 The base 6 includes a support seat. The first end of the support seat is rotatably connected to the first end of the lower connecting rod 5. The second end is provided with a first limiting shaft 601. The second end of the support seat is closer to the unfolded tabletop 1 than the first end. The first limiting shaft 601 acts as a first limiting structure and abuts against the upper connecting rod 3.

[0028] In a specific embodiment of this utility model, the first end of the support base is the lower end, the support base is installed vertically, the second end is located above the first end, the table 1 is vertically stored on one side of the column 7 when folded, and the table 1 is in a horizontal state when unfolded.

[0029] Furthermore, the support base includes two spaced-apart support side plates. The first end of each side plate has a support hole 602. A lower bushing 503 is positioned at a corresponding location on the lower connecting rod 5. The lower bushing 503 is connected to the support hole 602 on the support base via a screw, allowing rotation between them. The second end of the support base has a first limiting shaft 601. The upper connecting rod 3 laterally abuts against the first limiting shaft 601, ensuring it remains against the upper connecting rod 3 during folding and unfolding of the tabletop 1, thus limiting the position of the upper connecting rod 3 and providing support.

[0030] Furthermore, in this embodiment of the present invention, a second limiting shaft 603 is also provided on the support base. The first end of the second limiting shaft 603 near the support base is located on the rotation path of the first end of the lower connecting rod 5. The end of the first end of the lower connecting rod 5 is also provided with a limiting groove 504. When the table 1 is unfolded, the limiting groove 504 of the lower connecting rod 5 abuts against the second limiting shaft 603.

[0031] In this embodiment of the invention, a limiting groove 504 is provided at the very end of the first end of the lower connecting rod 5. When the lower connecting rod 5 rotates, it is not restricted by the second limiting shaft 603. It only abuts against the second limiting shaft 603 when the lower connecting rod 5 rotates to the fully unfolded position of the tabletop 1. This structure further stably supports the tabletop 1 in the unfolded state, improving the stability of the tabletop 1.

[0032] Furthermore, in this embodiment of the present invention, the upper connecting rod connecting hole 301 on the upper connecting rod 3 and the lower connecting rod connecting hole 502 on the lower connecting rod 5 are connected by a screw, which allows the upper connecting rod connecting hole 301 and the lower connecting rod connecting hole 502 to rotate.

[0033] In this embodiment of the utility model, when the tabletop 1 is folded, the connection points of the first limiting shaft 601, the support hole 602 and the upper and lower connecting rods 5 are approximately located on the same straight line, so that the tabletop 1 remains in a vertical state.

[0034] Furthermore, the base 6 also includes a connecting part, which is located near the first end of the support seat. The connecting part connects the support seat to the preset column 7 and makes the support part protrude from the column 7. Considering the action relationship between the lower connecting rod 5 and the upper connecting rod 3, this utility model sets the support part to protrude from the column 7. On the one hand, this avoids interference between the column 7 and the tabletop 1. On the other hand, it allows the tabletop 1 to be folded to the outside of the column 7 and unfolded to the inside of the column 7 in most positions during use, making it convenient for the user.

[0035] Specifically, in this embodiment of the invention, the base 6 consists of two H-shaped side plates spaced apart. The connecting portion also includes a base plate connected to the column 7. The base plate of the connecting portion is fixedly connected to the column 7. The thickness of the connecting portion is less than the thickness of the supporting portion, thus minimizing the space occupied when the connecting portion connects the entire base 6 to the column 7 and avoiding interference with the upper connecting rod 3 or the lower connecting rod 5. It can also connect to the column 7 to stably support the support base at a preset position, facilitating the folding and unfolding of the tabletop 1. Preferably, in this embodiment of the invention, the base 6 can be fixed to the column 7 by welding, screws, or other methods.

[0036] Furthermore, in this embodiment of the present invention, a tabletop support 2 is provided on the tabletop 1, a sliding groove 202 is provided at one end of the tabletop support 2, the second end of the upper connecting rod 3 is connected to the sliding groove 202, and a positioning hole 201 is provided at the other end of the tabletop support 2 for the lower connecting rod 5 to be rotatably connected, the second end of the lower connecting rod 5 is rotatably connected to the positioning hole 201.

[0037] Specifically, in this embodiment of the invention, a tabletop support 2 is installed on the bottom side of the tabletop 1. The tabletop support 2 includes two spaced-apart support side plates and a support base connecting the two support side plates. The support base is fixedly connected to the tabletop 1. One end of the support side plate is provided with a sliding groove 202. A connecting rod bushing 302 is provided on the upper connecting rod 3. The connecting rod bushing 302 and the sliding groove 202 are connected by a fixed rotating shaft 4 to achieve a sliding connection between the upper connecting rod 3 and the tabletop 1. The other end of the support side plate is provided with a positioning hole 201. A lower connecting rod bushing 501 is provided on the first end of the lower connecting rod 5. The lower connecting rod bushing 501 is connected to the positioning hole 201 by a screw to achieve a rotational connection between the lower connecting rod 5 and the tabletop 1.

[0038] In one embodiment of this utility model, the slide groove 202 is a straight structure as shown in the attached figure, which facilitates the smooth folding and unfolding of the tabletop 1. In some embodiments, in addition to the straight structure, the slide groove 202 also includes a limiting slide groove located on the other side perpendicular to the straight structure slide groove. When the tabletop 1 is unfolded, the upper connecting rod 3 slides into the limiting slide groove, further improving the overall stability of the tabletop 1 and preventing the tabletop 1 from being folded due to accidental collision.

[0039] Furthermore, in a specific embodiment of this utility model, the spacing between the supporting side plates is the same as the spacing between the bracket side plates. The widths of the upper connecting rod 3 and the lower connecting rod 5 are both smaller than the distance between the two sides of the tabletop bracket 2. At the same time, the widths of the upper connecting rod 3 and the lower connecting rod 5 are also smaller than the distance between the two supporting side plates, so that the upper connecting rod 3 and the lower connecting rod 5 are both located between the two bracket side plates and the two supporting side plates. After the tabletop 1 is folded, the upper connecting rod 3 and the lower connecting rod 5 are located inside the tabletop bracket 2, so that the tabletop 1 satisfies the foldable function while improving its aesthetics.

[0040] In a preferred embodiment of this utility model, the side of the table support 2 is also provided with a support groove for accommodating the support seat. After the table 1 is folded, part or all of the support seat is embedded in the support groove, so that the upper connecting rod 3 and the lower connecting rod 5 are accommodated in the space formed by the table support 2 and the support seat, making the overall structure more aesthetically pleasing.

[0041] Furthermore, in this embodiment of the invention, the tabletop 1 can also be provided with a corresponding slotted structure, which can be used to place tablets, mobile phones, etc., thereby increasing functionality.

[0042] This utility model embodiment provides a folding tabletop 1 structure. The first end of the lower connecting rod 5 is rotatably connected to the base 6, and the second end is rotatably connected to the first side of the tabletop 1. The first end of the upper connecting rod 3 is rotatably connected to the middle area of ​​the lower connecting rod 5, and the second end is slidably connected to the other side of the tabletop 1. When the tabletop 1 is unfolded, the second end of the upper connecting rod 3 slides towards the second end of the lower connecting rod 5, simultaneously causing the lower connecting rod 5 to rotate outward around the base 6 until the upper connecting rod 3 reaches its first limit position. At this point, the upper connecting rod 3, the lower connecting rod 5, and the tabletop 1 form a stable triangular structure, providing stable support for the tabletop 1. When the tabletop 1 is folded, the second end of the upper connecting rod 3 slides away from the second end of the lower connecting rod 5, simultaneously causing the lower connecting rod 5 to rotate inward around the base 6 until the upper connecting rod 3 reaches its second limit position. At this point, both the upper connecting rod 3 and the lower connecting rod 5 are close to the tabletop 1, reducing the overall volume of the structure. This utility model uses a clever structural design to functionally install the tabletop 1 on fitness equipment, resulting in a simple, stable, reliable, and high-strength structure.
