DETAILED DESCRIPTION

[0038] The technical solution of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments, not all embodiments. Based on the embodiments provided in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0039] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0040] The terms "first," "second," and so on, in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a component or device comprising one or more parts is not limited to the one or more parts listed, but may optionally include one or more parts that are not listed but are inherent to the illustrated product, or one or more parts that should be present based on the described functionality.

[0041] Due to limitations in manufacturing processes and tolerances, rigidly mated rails cannot guarantee absolute smooth operation and stable lifespan. For example, in a dual-track system, unevenness or tolerances can narrow the distance between the two tracks, preventing the two pulleys from passing. Therefore, slides require high dimensional accuracy. Products using rails are subject to significant constraints in terms of size, space, and cost. Pulleys rely heavily on the precision of component fit, resulting in limited adaptability.

[0042] See also Figure 1 and Figure 2 The present application provides an elastic wheel module 100 that improves the adaptability of the pulley and reduces the dependence on the accuracy of part matching.

[0043] See also Figure 1 and Figure 2 The elastic wheel module 100 includes a fixed bracket 10 , a movable block 20 , an elastic member 30 and a pulley 40 .

[0044] See also Figure 1 and Figure 2 The fixing bracket 10 has a receiving groove 11 .

[0045] The movable block 20 is slidably disposed within the receiving groove 11. The movable block 20 is capable of sliding within the receiving groove 11 along a first direction. The first direction is the Z direction. Optionally, the receiving groove 11 may be a sliding groove for the movable block 20 along the first direction. The fixed bracket 10 may be a fixed seat, and the movable block 20 may be a slider slidably connected to the fixed seat.

[0046] See also Figure 1 and Figure 2The fixing bracket 10 includes a base plate 12 and a first side plate 13 and a second side plate 14 protruding from the base plate 12. The first side plate 13 and the second side plate 14 both extend along a first direction. The first side plate 13 and the second side plate 14 are arranged opposite each other along a third direction. The third direction is the Y direction. A hollow hole is defined in the base plate 12, which passes through the base plate 12 along the Y direction. The hollow hole can reduce the weight of the base plate 12, thereby reducing the weight of the elastic wheel module 100. In some application scenarios, it can also form an avoidance space or a storage space to increase the compactness of the structural assembly.

[0047] See also Figure 1 and Figure 2 The fixing bracket 10 further includes a bottom plate 15 , which is arranged along the third direction. The first side plate 13 , the second side plate 14 and the bottom plate 15 surround and form the receiving groove 11 .

[0048] The first side plate 13 and the second side plate 14 respectively form two side walls of the receiving groove 11 , and the bottom plate 15 forms a bottom wall of the receiving groove 11 .

[0049] Optionally, the pulley 40 is disposed on one side of the movable block 20 in the second direction. The pulley 40 and the movable block 20 are arranged along the second direction. Further, optionally, the pulley 40 is fixedly connected to the movable block 20 in the second direction. The pulley 40 is located outside the receiving groove 11. Specifically, the pulley 40 is fixed to the movable block 20 in the second direction via screws. The diameter of the pulley 40 is smaller than the dimension of the movable block 20 in the third direction.

[0050] The second direction is perpendicular to the first direction. The first direction is the Z direction, and the second direction is the X direction.

[0051] The elastic member 30 is disposed in the receiving groove 11. The elastic member 30 elastically abuts between the bottom wall of the receiving groove 11 and the movable block 20. The movable block 20, the elastic member 30 and the bottom wall (bottom plate 15) of the receiving groove 11 are sequentially arranged along the first direction.

[0052] The elastic member 30 includes, but is not limited to, a metal elastic member 30 and a non-metallic elastic member 30. Metal elastic members 30 include, but are not limited to, leaf springs, coil springs, and torsion bar springs. Non-metallic elastic members 30 include, but are not limited to, rubber springs and plastic springs. The elastic member 30 may include, but is not limited to, a tension spring, a compression spring, a torsion spring, a coil spring, and the like, depending on how the elastic force is generated.

[0053] The elastic member 30 is capable of elastically deforming along the first direction. Specifically, an elastic space is defined between the movable block 20 and the bottom wall (bottom plate 15) of the receiving groove 11. At least a portion of the elastic member 30 is disposed within the elastic space, and the elastic member 30 is capable of elastically deforming along the first direction within the elastic space.

[0054] Unevenness or tolerance of the track may cause the distance between the two tracks to become narrower. For example, there is a protrusion on a part of the guide rail. The pulley 40 moves upward in the first direction when the guide rail protrusion is raised. The movable block 20 can move upward in the first direction relative to the fixed bracket 10 to smoothly pass through the guide rail protrusion while keeping the position of the fixed bracket 10 unchanged, thereby improving the adaptability of the pulley 40 and reducing the dependence on the guide rail matching accuracy.

[0055] The elastic wheel module 100 provided in the present application includes a fixed bracket 10, a movable block 20, an elastic member 30 and a pulley 40. The fixed bracket 10 has a receiving groove 11; the movable block 20 is arranged in the receiving groove 11, and the movable block 20 can slide in the receiving groove 11 along a first direction; the elastic member 30 is arranged in the receiving groove 11, and the elastic member 30 elastically abuts between the bottom wall of the receiving groove 11 and the movable block 20, and the elastic member 30 can be elastically deformed along the first direction; the pulley 40 is fixedly connected to the movable block 20 along a second direction, and the second direction is perpendicular to the first direction; in this way, the pulley 40 can move relative to the fixed bracket 10 along the first direction with the movable block 20, and then when encountering unevenness or tolerance of the track that may cause the spacing between the double tracks to narrow, the pulley 40 can absorb the tolerance by moving along the first direction, thereby improving the adaptability of the pulley 40 and reducing dependence on the accuracy of part matching.

[0056] The elastic wheel module 100 provided in the present application has low dependence on the accuracy of the guide rail, can greatly reduce the number of parts, and has low cost; the modular design facilitates assembly to adapt to more application scenarios.

[0057] Optionally, the elastic member 30 is a spring sheet, such as a bent metal spring sheet.

[0058] Optionally, the elastic member 30 is a spring sheet, and the elastic member 30 includes an elastic arm (such as Figures 3 to 5 The abutment end 32 in the elastic arm and the first catch arm at both ends of the elastic arm (such as Figures 3 to 5 The first catch end 31) and the second catch arm (such as Figures 3 to 5 The second grab end 33 in the elastic arm is provided, wherein the first grab arm and the second grab arm are arranged opposite to each other, and the first grab arm and the second grab arm are both bent relative to the elastic arm, for example, the bending angle is about 90°. The first grab arm is bent toward the side where the second grab arm is located, and the second grab arm is bent toward the side where the first grab arm is located. The elastic arm is connected between the first grab arm and the second grab arm, and the middle part of the elastic arm has at least one bending arch, and the protruding side of the bending arch is opposite to the side where the first grab arm and the second grab arm are located, and the elastic arm can be elastically deformed in the first direction. Of course, in other embodiments, the protruding part of the bending arch in the middle part of the elastic arm can also be the side where the first grab arm and the second grab arm are located. The first grab arm and the second grab arm provide a clamping force that approaches each other, so that the elastic member 30 and the clamping movable block 20 are clamped.

[0059] See also Figures 3 to 5 The elastic member 30 includes a first catch end 31, an abutting end 32 and a second catch end 33 that are interconnected in sequence. The first catch end 31 is the aforementioned first catch arm, the abutting end 32 is the aforementioned elastic arm, and the second catch end 33 is the aforementioned second catch arm.

[0061] Optionally, the first catch end 31 is C-shaped. The second catch end 33 is C-shaped. The first catch end 31 and the second catch end 33 are disposed opposite each other along a third direction. The abutment end 32 is connected to one end of the first catch end 31 and one end of the second catch end 33. The abutment end 32 is bent, for example, in a generally convex arc shape.

[0062] In the first alternative embodiment, see Figures 3 to 5 The two side walls of the movable block 20 are respectively provided with a first recessed portion 21 and a second recessed portion 22. The first recessed portion 21 and the second recessed portion 22 divide the movable block 20 into a first main block 23 and a second main block 24. The dimension of the second main block 24 along the third direction is smaller than that of the first main block 23 along the third direction.

[0063] The elastic member 30 covers the outer circumference of the second main body block 24 .

[0064] The first catch end 31 is caught in the first recessed portion 21, and the second catch end 33 is caught in the second recessed portion 22. Furthermore, the first catch end 31 is caught in one side wall of the second main body block 24, and the second catch end 33 is caught in another side wall of the second main body block 24, thereby improving the engagement tightness between the elastic member 30 and the movable block 20 and facilitating assembly of the elastic member 30 and the movable block 20.

[0065] The abutting end 32 is located between the bottom wall of the movable block 20 and the bottom wall of the receiving groove 11 .

[0066] The abutting end 32 elastically abuts the bottom wall (bottom plate 15) of the receiving groove 11. The abutting end 32 is spaced apart from the bottom wall of the movable block 20. An elastic deformation gap is defined between the abutting end 32 and the bottom wall of the movable block 20. This allows the abutting end 32 to elastically deform toward the bottom wall of the movable block 20. Furthermore, the middle portion of the abutting end 32 is spaced apart from the bottom wall of the movable block 20.

The first guide portion 16 is slidably connected to the groove wall of the third guide portion 25. The second guide portion 17 is slidably connected to the groove wall of the fourth guide portion 26.

[0072] The first guide portion 16 cooperates with the third guide portion 25, and the second guide portion 17 cooperates with the fourth guide portion 26 to limit the movable block 20 in the second direction and the third direction, so as to ensure the stability of the movable block 20 in the second direction and the third direction, and to reserve sufficient freedom for the movable block 20 in the first direction.

[0073] Furthermore, the third guide portion 25 and the fourth guide portion 26 are respectively provided on opposite sides of the first main body block 23. The length of the first guide portion 16 along the first direction is greater than the length of the third guide portion 25 along the first direction, and the length of the second guide portion 17 along the first direction is greater than the length of the fourth guide portion 26 along the first direction.

In yet another optional embodiment, the movable block 20 facing away from the elastic member 30 is provided with a protrusion and an inner recess.

[0077] For specific options, see Figure 4 and Figure 7 The top of the receiving groove 11 has two avoidance portions (a first avoidance portion 181 and a second avoidance portion 183), and the two avoidance portions are located on both sides of the limiting portion. The side of the movable block 20 facing away from the elastic member 30 includes two protrusions (a first protrusion 27 and a second protrusion 29), and the two protrusions are respectively opposite to the two avoidance portions. Furthermore, an inner concave portion ( Figure 7 The movable block 20 includes a first inner recess 28, the inner recess facing a stopper. By providing the inner recess on the movable block 20 and facing the stopper, the movable block 20 can increase its travel when moving toward the top plate 18 and reduce its weight.

[0111] The present application provides an elastic wheel module 100 including a pulley 40, a movable block 20, an elastic member 30 and a fixed bracket 10. A pair of flanges (a first guide portion 16 and a second guide portion 17) are provided on the inner side of the fixed bracket 10 to cooperate with the recesses (a third guide portion 25 and a fourth guide portion 26) provided on both sides of the movable block 20.

When the pulley 40 encounters a bend or deformation of the track, it can use the deformation of the elastic member 30 to correct itself. The elastic wheel module 100 provided in this application has low dependence on the guide rail accuracy, can greatly reduce the number of parts, and has low cost; the modular design facilitates assembly, miniaturization, more constant elastic force output, and more stable service life to adapt to more application scenarios.

[0112] See also Figure 14 An embodiment of the present application provides a first guide rail assembly 200, which includes a supporting bracket 210, a first guide rail 220, a second guide rail 230, a first pulley set 240, a second pulley set 250 and a sliding seat 260.

[0113] The first guide rail 220 and the second guide rail 230 are fixed side by side on the support bracket 210 along a first direction. The first pulley assembly 240 and the second pulley assembly 250 are fixed on the sliding base 260 along the first direction. The first pulley assembly 240 can be the elastic wheel module 100 of any of the above-mentioned embodiments; and / or the second pulley assembly 250 can be the elastic wheel module 100 of any of the above-mentioned embodiments. The pulley 40 in the first pulley assembly 240 is slidably connected to the first guide rail 220. The pulley 40 in the second pulley assembly 250 is slidably connected to the second guide rail 230.

[0114] Optionally, the cross-section of the first guide rail 220 is circular or convex. The cross-section of the second guide rail 230 is circular or convex.

The first pulley assembly 240 and the second pulley assembly 250 are disposed between the first guide rail 220 and the second guide rail 230.

[0115] Since the first pulley set 240 and the second pulley set 250 are fixed on the sliding seat 260 along the first direction, the distance between the fixing bracket 10 of the first pulley set 240 and the second pulley set 250 is relatively fixed.

[0116] When the distance between the first guide rail 220 and the second guide rail 230 changes, for example, when it becomes smaller, the pulley 40 in the first pulley assembly 240 can move along the first direction toward the side where the second pulley assembly 250 is located to accommodate the smaller distance between the first guide rail 220 and the second guide rail 230. When the distance between the first guide rail 220 and the second guide rail 230 changes, for example, when it becomes larger, the pulley 40 in the first pulley assembly 240 can move along the first direction away from the second pulley assembly 250 to accommodate the larger distance between the first guide rail 220 and the second guide rail 230.

[0117] When the distance between the first guide rail 220 and the second guide rail 230 changes, for example, when it becomes smaller, the pulley 40 in the second pulley assembly 250 can move along the first direction toward the side where the first pulley assembly 240 is located to accommodate the smaller distance between the first guide rail 220 and the second guide rail 230. When the distance between the first guide rail 220 and the second guide rail 230 changes, for example, when it becomes larger, the pulley 40 in the second pulley assembly 250 can move along the first direction away from the first pulley assembly 240 to accommodate the larger distance between the first guide rail 220 and the second guide rail 230.

[0118] When the distance between the first guide rail 220 and the second guide rail 230 changes, for example, when it becomes smaller, the pulley 40 in the second pulley set 250 can move in the first direction toward the side where the first pulley set 240 is located, and the pulley 40 in the first pulley set 240 can move in the first direction toward the side where the second pulley set 250 is located, so as to adapt to the problem of the smaller distance between the first guide rail 220 and the second guide rail 230. When the distance between the first guide rail 220 and the second guide rail 230 changes, for example, when it becomes larger, the pulley 40 in the second pulley set 250 can move in the first direction away from the first pulley set 240, and the pulley 40 in the first pulley set 240 can move in the first direction away from the second pulley set 250, so as to adapt to the problem of the larger distance between the first guide rail 220 and the second guide rail 230.

The pulley 40 in the first pulley group 240 and / or the second pulley group 250 can move along the first direction relative to the fixed bracket 10 with the movable block 20. When encountering unevenness or tolerance of the track that may cause the spacing between the double tracks to narrow, the pulley 40 can absorb the tolerance by moving along the first direction, thereby improving the adaptability of the pulley 40 and reducing dependence on the accuracy of part matching, so as to improve the guiding stability and smoothness of the first guide rail assembly 200.
