[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0041] Planar motors are widely used due to their non-contact motion between the mover and stator. However, in some applications, the weight of some objects may exceed the load-bearing capacity of the mover. In this case, the mover cannot float above the stator. As a result, when the mover is running, friction occurs between the mover and the stator, causing wear on both the mover and the stator.

[0042] Based on this, an exemplary embodiment of this application provides a mover support frame assembly, including a support frame, a rolling part, and a stop part. The support frame is connected to the mover, and the support frame is provided with a receiving groove. The rolling part is disposed in the receiving groove, and the stop part covers the receiving groove, with a portion of the rolling part exposed outside the stop part. Thus, when the weight of the object carried by the mover exceeds the load-bearing capacity of the mover, the mover achieves relative movement with the stator through the rolling part, which can reduce the friction between the mover and the stator, reduce wear between the mover and the stator, and improve the life and applicability of the planar motor.

[0043] Example 1:

[0044] An exemplary embodiment of this application provides a moving element support frame assembly, such as... Figures 1 to 4As shown, the mover support frame assembly includes a support frame 101, a rolling part 102, and a stop part 103. The support frame 101 has multiple receiving slots, the size of which is larger than the size of the rolling part 102. The rolling part 102 is disposed within the receiving slots, allowing it to roll freely within the slots. The stop part 103 covers the receiving slots, with a portion of the rolling part 102 protruding outside the stop part 103. The stop part 103 prevents the rolling part 102 from dislodging from the receiving slots during movement. Thus, when the weight of the object carried by the mover exceeds its load-bearing capacity, the mover achieves relative movement with the stator via the rolling part 102, reducing friction between the mover and stator, alleviating wear, and improving the lifespan and applicability of the planar motor.

[0045] There are various configurations for the support frame 101, and the appropriate configuration can be selected according to the weight of the object being supported.

[0046] For example, such as Figure 2 and 3 As shown, the support frame 101 includes a first support portion 1011 and a second support portion 1012 disposed opposite to each other, forming an installation space for mounting the mover body 200 between the first support portion 1011 and the second support portion 1012. Both the first support frame 101 and the second support frame 101 are provided with multiple receiving grooves, and the rolling portion 102 is movably disposed within the receiving grooves. This type of support frame 101 is lightweight and has a small mass, reducing the overall weight of the planar motor mover. To facilitate the installation of the mover body 200, a connecting plate can be provided between the first support frame 101 and the second support frame 101. The first support frame 101, the second support frame 101, and the connecting plate are integrally formed, together enclosing the installation space for mounting the mover body 200, facilitating the positioning of the mover body 200 during installation.

[0047] like Figure 4 As shown, the support frame 101 may further include a third support portion 1013 and a fourth support portion 1014 disposed opposite to each other; the first support portion 1011, the second support portion 1012, the third support portion 1013, and the fourth support portion 1014 are integrally formed and together enclose the mounting space for mounting the mover body 200. The mover body 200 is embedded in the support frame 101, and the mover body 200 is surrounded by the support frame 101, which can stably support the mover to run on the stator.

[0048] like Figure 5As shown, for example, the support frame 101 may further include a fifth support portion 1015; one end of the fifth support portion 1015 is connected to the middle section of the first support portion 1011, and the other end is connected to the middle section of the second support portion 1012; the first support portion 1011, the second support portion 1012, the third support portion 1013, the fourth support portion 1014, and the fifth support portion 1015 are integrally formed. The first support portion 1011, the fifth support portion 1015, the third support portion 1013, and the second support portion 1012 together enclose the installation space of the first moving part body; the first support portion 1011, the fifth support portion 1015, the fourth support portion 1014, and the second support portion 1012 together enclose the installation space of the second moving part body. In this case, the first moving part body and the second moving part body jointly carry the item, which can be applied to scenarios where the weight of the item carried is greater.

[0049] For example, the rolling part 102 can be a ball bearing, or it could be a swivel caster. The ball bearing can be made of ceramic, silicon carbide, silicon nitride, or engineering plastics such as PEEK or PA66. The support frame 101 can be made of engineering plastic. Figures 4 to 8 As shown, the position and number of the rolling parts 102 can also take various forms. The appropriate arrangement of the rolling parts 102 is selected based on the weight of the object being carried. When the weight of the object carried by the moving part is large, a configuration such as... Figure 4 The rolling part 102 shown is arranged in a dense form; when the weight of the object carried by the moving part is relatively small, it can be selected as follows: Figures 6 to 8 The rolling section 102 shown is arranged in a relatively sparse form.

[0050] Example 2:

[0051] Based on the above embodiment 1, in this embodiment, as follows: Figure 9 and 10 As shown, the support frame 101 is also provided with a first snap-fit ​​part 1016 or a first snap-fit ​​groove 1017. For example... Figure 11 As shown, when the first support frame 101 is provided with a first snap-fit ​​part 1016 and the second support frame 101 is provided with a first snap-fit ​​groove 1017, the first snap-fit ​​part 1016 and the first snap-fit ​​groove 1017 are mutually adapted, so that the first snap-fit ​​part 1016 can snap into the first snap-fit ​​groove 1017, enabling quick connection and disassembly between the first support frame 101 and the second support frame 101 through snap-fit. When the first moving part is installed in the first support frame 101 and the second moving part is installed in the second support frame 101, quick connection and disassembly of the first moving part and the second moving part can be achieved, making the planar motor applicable to various scenarios and improving the applicability of the planar motor.

[0052] like Figure 12As shown, the support frame 101 can be provided with a first snap-fit ​​part 1016 and a first snap-fit ​​groove at the same time. At this time, the first snap-fit ​​part 1016 and the first snap-fit ​​groove are provided on opposite sides of the support frame 101. In this way, multiple support frames 101 can be combined with each other, and multiple moving body bodies 200 can be combined with each other.

[0053] For example, the other two sides of the support frame 101 may also be provided with a first snap-fit ​​portion 1016 and a first snap-fit ​​groove, so as to realize the combination of multiple support frames 101 in multiple directions, realize the mutual combination between multiple mover bodies 200, improve the load-bearing capacity of the mover, and make the planar motor applicable to a variety of scenarios, thereby improving the applicability of the planar motor.

[0054] like Figure 13 As shown, when the first support frame 101 is provided with the first moving body and the second moving body, and the second support frame 101 is provided with the third moving body and the fourth moving body, the rapid connection and disassembly of multiple moving bodies 200 can be realized through the rapid connection and disassembly of the first support frame 101 and the second support frame 101.

[0055] like Figures 14 to 17 As shown, the mover support frame assembly may further include a connecting portion 300; the connecting portion 300 is provided with a second snap-fit ​​portion 301 or a second snap-fit ​​groove 302; or the connecting portion 300 is provided with a second snap-fit ​​portion 301 and a second snap-fit ​​groove, the first snap-fit ​​portion 1016 is adapted to the second snap-fit ​​groove 302; the first snap-fit ​​groove 1017 is adapted to the second snap-fit ​​portion 301. One side of the connecting portion 300 is snapped with the first support frame 101, and the other side is snapped with the second support frame 101, which enables quick connection and disassembly between multiple support frames 101, and thus enables quick connection and disassembly between multiple mover bodies 200.

The mover support frame assembly 100 and the mover body 200 can be connected by means of adhesive, fasteners, or other methods.

[0058] For example, such as Figures 1 to 4 As shown, a mover may include a mover support frame assembly 100 and a mover body 200; the mover body 200 is fixedly connected within the mover support frame assembly 100.

[0059] like Figure 13As shown, a mover may include multiple mover support frame assemblies 100 and multiple mover bodies 200; each mover support frame assembly 100 is provided with one or more mover bodies 200; the multiple mover support frame assemblies 100 are detachably connected to each other.
