The fastening washer and the fastening nut are sequentially sleeved on the transmission link. One side of the fastening washer abuts against the magnet, and the fastening nut abuts against the other side of the fastening washer.

[0015] According to the present invention, an electromagnetic rhythmic base frame is provided, wherein a frame is provided on the movable frame, the frame is arranged around the electromagnetic coil body, and the transmission component is fixedly connected to the frame.

[0016] According to the present invention, an electromagnetic rhythmic base frame is provided, the electromagnetic rhythmic base frame further includes a guide mechanism, one end of the guide mechanism is connected to the fixed frame, and the other end of the guide mechanism is connected to the movable frame, the guide mechanism is used to guide the movable frame to move relative to the fixed frame.

[0017] According to the electromagnetic rhythmic base frame provided by this utility model, the guiding mechanism includes:

[0018] Guide elastic plate;

[0019] The first fixing unit includes a first fixing member, a first pressing member, and a first connecting structure. One end of the guide elastic plate is sandwiched between the first fixing member and the first pressing member, and one end of the guide elastic plate, the first fixing member, and the first pressing member are fixedly connected to the fixing frame through the first connecting structure.

[0020] The second fixing unit includes a second fixing member, a second pressing member, and a second connecting structure. The other end of the guide elastic plate is sandwiched between the second fixing member and the second pressing member. The other end of the guide elastic plate, the second fixing member, and the second pressing member are fixedly connected to the movable frame through the second connecting structure.

[0021] The first fixing member has a first limiting concave surface, and the second fixing member has a second limiting concave surface. The widths of both the first and second limiting concave surfaces are adapted to the width of the guide elastic plate.

[0022] According to the present invention, an electromagnetic rhythmic base frame is provided, wherein the fixed frame is provided with a first magnetic module at each of its opposite ends, and the movable frame is provided with a second magnetic module at each of its opposite ends, wherein the first magnetic module and the second magnetic module are one-to-one corresponding and spaced apart.

[0023] The magnetic poles at opposite ends of the first magnetic module and the second magnetic module are the same.

[0024] According to the present invention, an electromagnetic rhythmic base frame is provided, wherein the first magnetic module includes a first mounting plate, two first magnetic pillars and a first anti-collision block, the two first magnetic pillars are connected to the first mounting plate at intervals, the first anti-collision block is connected to the first mounting plate and is located between the two first magnetic pillars;

[0029] The electromagnetic rhythmic base frame provided by this utility model generates magnetic force through the conduction of the electromagnetic coil body and the magnetic field change between the conduction of the electromagnetic coil body and the two magnets. Because the electromagnetic coil body is connected to the fixed frame and the two magnets are connected to the movable frame, the magnetic field affects the movable frame, thereby causing relative movement between the fixed frame and the movable frame through magnetic force. The electromagnetic coil body has a movement channel to accommodate the movement of the magnets and transmission components, allowing the two magnets to move freely within the channel without being fixed or restricted. In the stationary state, parts of the two magnets extend into the movement channel. That is, when the magnets are located in a certain position within the movement channel but not moving, the orthographic projections of the parts of the movement channel and the magnets overlap, meaning there is still some overlap between the electromagnetic coil body and the magnets. Therefore, when switching from a stationary state to a moving state, the magnetic field between the electromagnetic coil body and the two magnets can change rapidly. In the moving state, when the two magnets move within the movement channel, the degree of overlap between the orthographic projections of the movement channel and the magnets changes, but the orthographic projections still overlap, indicating that there is still a physical connection and interaction between them. This helps ensure a good working state between the electromagnetic coil body and the two magnets, generating sufficient magnetic force so that the electromagnet drive mechanism can effectively achieve relative movement between the fixed frame and the movable frame.

[0030] By setting the electromagnetic drive mechanism as a set, the rhythmic base frame uses the magnetic power seat as the driving force, resulting in better consistency and higher efficiency. This avoids the problem of interference in the driving force, and the rhythmic base frame can quickly achieve regular movement.

[0031] By setting the cross-sectional shape of the electromagnetic coil body to a square, it is helpful to reduce the height of the electromagnetic coil body, thereby lowering the center of gravity of the rhythmic furniture and improving the stability of the rhythmic furniture when operating at high frequencies.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] The following is combined Figures 1-7 This invention describes an electromagnetic rhythmic base frame and rhythmic furniture. The rhythmic furniture includes a massage body that supports the user and an electromagnetic rhythmic base frame disposed at the bottom of the massage body. It should be noted that in some embodiments of this invention, the rhythmic furniture is a rhythmic chair, with the electromagnetic rhythmic base frame located at the bottom of the chair; naturally, in some embodiments, the electromagnetic rhythmic base frame can be applied to furniture such as rhythmic sofas or rhythmic beds.

[0046] Reference Figure 1 and Figure 2 According to this utility model, an electromagnetic rhythmic base frame is provided, including a fixed frame 100, a movable frame 200, and an electromagnetic drive mechanism 300. The movable frame 200 is vertically arranged and movably connected to the fixed frame 100, and the movable frame 200 reciprocates relative to the fixed frame 100. The electromagnetic drive mechanism 300 includes an electromagnetic coil body 310, two magnets 320, and a transmission assembly 330. The electromagnetic coil body 310 is fixedly connected to the fixed frame 100, and the two magnets 320 are arranged front to back on the transmission assembly 330. The electromagnetic coil body 310 is fixedly connected to the movable frame 200. The electromagnetic coil body 310 and the two magnets 320 generate magnetic force through magnetic field changes, so that the movable frame 200 moves back and forth relative to the fixed frame 100. The electromagnetic drive mechanism 300 is a set. The electromagnetic coil body 310 has a moving channel 311. The transmission component 330 is movably inserted through the moving channel 311. The two magnets 320 extend into the moving channel 311 from both ends of the electromagnetic coil body 310, and the magnetic poles of the two magnets 320 at opposite ends are the same.

[0047] The electromagnetic rhythmic base frame provided by this utility model utilizes an electromagnetic coil body 310 for conductivity. The electromagnetic coil body 310 conducts electricity, and magnetic force is generated between the two magnets 320 through magnetic field changes. Since the electromagnetic coil body 310 is connected to the fixed frame 100 and the two magnets 320 are connected to the movable frame 200, the magnetic field affects the movable frame 200, thereby causing relative movement between the fixed frame 100 and the movable frame 200 through magnetic force. The electromagnetic coil body 310 has a moving channel 311 to accommodate the movement of the magnets 320 and the transmission assembly 330, allowing the two magnets 320 to move freely within the moving channel 311 without being fixed or restricted. In a static state, parts of the two magnets 320 extend into the moving channel 311. That is, when the magnets 320 are located at a certain position in the moving channel 311 but do not move, the orthographic projection of the partial structure between the moving channel 311 and the magnets 320 will exist. The overlap means that there is still a certain degree of overlap between the electromagnetic coil body 310 and the magnet 320. Therefore, when switching from a static state to a moving state, the magnetic field between the electromagnetic coil body 310 and the two magnets 320 can be changed quickly. In the moving state, when the two magnets 320 move in the moving channel 311, the degree of overlap of the orthographic projection between the moving channel 311 and the magnets 320 will change, but the orthographic projections of the two still overlap, and there is still a physical connection and interaction between them. This helps to ensure a good working state between the electromagnetic coil body 310 and the two magnets 320, generate sufficient magnetic force, and enable the electromagnet 320 drive mechanism to effectively realize the relative movement of the fixed frame 100 and the moving frame 200.

[0048] By setting the electromagnetic drive mechanism 300 as a group, the rhythmic base frame uses the magnetic power seat as the driving force, resulting in better consistency and higher efficiency. This avoids the problem of interference in the driving force, and the rhythmic base frame can quickly achieve regular movement.

[0049] It should be noted that in this embodiment of the utility model, there is a fitting gap between the outer wall of the two magnets 320 and the inner wall of the moving channel 311. The function of the fitting gap is to ensure that the two magnets 320 can move smoothly in the moving channel 311, which helps to avoid collision between the electromagnetic coil body 310 and the two magnets 320, and also avoids friction or jamming.

[0050] It should also be noted that, in this embodiment of the invention, since the magnetic poles at opposite ends of the two magnets 320 are the same (i.e., both are N poles or both are S poles), by changing the direction of the current in the electromagnetic coil body 310, it is possible to control whether the magnetic field generated by the electromagnetic coil body 310 attracts or repels one end of the magnet 320. The aforementioned attraction or repulsion force can drive the transmission component 330 to move along the moving channel 311. Since the magnetic poles at opposite ends of the two magnets 320 are the same, changing the direction of the current will simultaneously change the nature of the interaction between the two magnets 320 and the electromagnetic coil body 310 (from attraction to repulsion, or from repulsion to attraction), so as to control the movement direction of the transmission component 330. By utilizing the principle of electromagnetic induction, highly precise motion control of the transmission component 330 can be achieved. By adjusting the current intensity of the electromagnetic coil body 310, the intensity of the magnetic field generated by the electromagnetic coil body 310 can be controlled, thereby controlling the magnitude of the attraction or repulsion force on the magnet 320, reducing mechanical wear, improving the reliability and lifespan of the electromagnet 320 drive mechanism, and making it suitable for various precision control applications.

[0051] Understandably, referring to Figure 1 In some embodiments of this utility model, the movable frame 200 covers the fixed frame 100 in the vertical direction, and the movable frame 200 moves back and forth relative to the fixed frame 100. The cross-sectional area of ​​the movable frame 200 is larger than that of the fixed frame 100. In this embodiment, the movable frame 200 is connected to the massage body, which can be understood as a sofa cushion or mattress, and is not limited here. Specifically, in this utility model embodiment, the magnet 320 is a neodymium iron boron magnet 320. Using neodymium iron boron magnet 320 as the core of the magnet 320 has high remanence and coercivity, and can generate a strong magnetic field, thus having high magnetism. Secondly, compared with other permanent magnet materials, neodymium iron boron magnet 320 has a higher operating temperature range and can maintain good magnetic properties in high-temperature environments. Neodymium iron boron magnet 320 has a high magnetic energy product, which means that under the same magnetic properties, smaller and lighter magnets can be manufactured, which is beneficial to reducing the volume and weight of the base frame. Specifically, in this embodiment, the neodymium iron boron magnet 320 is selected as a high-magnetic neodymium iron boron magnet 320.

[0052] Specifically, refer to Figure 2 In this embodiment, a gap is provided between the two magnets 320. The two magnets 320 arranged at intervals are beneficial to reduce mutual interference between them and improve the reliability of operation.

[0053] Understandably, referring to Figure 2In this embodiment of the invention, a partition plate 430, on which a transmission assembly 330 is sleeved, is provided between the two magnets 320. One end of the partition plate 430 abuts against one of the magnets 320, and the other end of the partition plate 430 abuts against the other magnet 320. By adopting the above structure, the presence of the partition plate 430 can isolate the magnetic field transmission between the two magnets 320. By reasonably designing the partition plate 430, the magnetic field strength of the magnetic unit can be enhanced. The partition plate 430 can also concentrate the magnetic field lines, making the magnetic field more concentrated and stronger, thereby achieving the desired magnetic field direction effect.

[0054] Specifically, in this embodiment, the partition plate 430 is a stainless steel sheet, which has a simple structure, is easy to assemble, and has a low manufacturing cost. Of course, in some embodiments, the partition plate 430 may also be a separating film, etc., and this is not limited here.

[0055] Specifically, refer to Figure 1 and Figure 2 In this embodiment of the present invention, the transmission assembly 330 includes two transmission links 331, each of which passes through two magnets 320, and the end of each transmission link 331 is fixedly connected to the movable frame 200; wherein, each transmission link 331 is provided with two sets of fastening structures, the two magnets 320 are located between the two sets of fastening structures, and the fastening structures abut against one side of the corresponding adjacent magnet 320, the fastening structures being used to restrict the movement of the magnets 320 relative to the transmission links 331. By adopting the above structure, the arrangement of two transmission links 331 and two sets of fastening structures in the transmission component 330 can effectively limit the rotation of the magnet 320 relative to the transmission link 331, avoiding noise generation. This also limits the rotation of the magnet 320 relative to the transmission link 331, providing a stable magnetic power transmission effect. Specifically, when one transmission link 331 and the magnet 320 become loose, the other transmission link 331 remains fixed to the magnet 320 under the action of the fastening structure, which helps reduce noise. Furthermore, through the cooperation of the two sets of fastening components on the two transmission links 331, by adjusting the appropriate fastening force, it is possible to ensure that the transmission link 331 and the magnet 320 are relatively fixed, preventing the magnet 320 from cracking due to excessive fastening force, thereby ensuring the reliability and stability of the electromagnetic drive mechanism 300.

[0056] Of course, refer to Figure 5In some embodiments, the transmission assembly 330 includes a transmission link 331, which passes through two magnets 320, and the ends of the transmission links 331 are fixedly connected to the movable frame 200. The transmission links 331 have two sets of fastening structures, with the two magnets 320 located between the two sets of fastening structures. The fastening structures abut against one side of the corresponding adjacent magnet 320, and the fastening structures restrict the movement of the magnets 320 relative to the transmission links 331, while still achieving the aforementioned transmission effect. It should be noted that the number of transmission links 331 in the transmission assembly 330 is not limited here; it can also be three, four, etc.

[0057] Specifically, refer to Figure 2 In this embodiment of the utility model, the transmission link 331 has a first threaded portion, and the fastening structure includes a fastening washer 410 and a fastening nut 420. The fastening washer 410 and the fastening nut 420 are sequentially sleeved on the transmission link 331. One side of the fastening washer 410 abuts against the magnet 320, and the fastening nut 420 abuts against the other side of the fastening washer 410. The fastening nut 420 is threadedly connected to the first threaded portion of the transmission link 331.

[0058] With the above configuration, the fastening washer 410 can form a tight connection between it and the two magnets 320. The fastening washer 410 and the magnets 320 abut each other, increasing the contact area, which can achieve a tight connection and prevent loosening, thereby improving the performance and reliability of the electromagnetic drive.

[0059] It should be noted that the aforementioned fixing washer 410 is a positioning iron ring or a positioning rubber ring, etc., and is not limited here.

[0060] Understandably, referring to Figure 1 and Figure 2 In this embodiment of the invention, the movable frame 200 is provided with a frame 500, which surrounds the electromagnetic coil body 310. The transmission component 330 is fixedly connected to the frame 500. With the above structure, the frame 500 surrounds the electromagnetic coil body 310, which means that the electromagnetic coil body 310 and the transmission component 330 equipped with the magnet 320 can move relative to each other. The frame 500 plays a protective role, which helps to ensure the stability and reliability of the rhythmic base frame.

[0061] Specifically, refer to Figure 1 and Figure 2In this embodiment of the invention, the frame 500 includes two connecting plates 510 and two side plates 520. The two connecting plates 510 are spaced apart and facing each other, and the two side plates 520 are spaced apart and facing each other, with the two side plates 520 located between the two connecting plates 510. The two connecting plates 510 and the two side plates 520 are connected end to end in sequence. Each transmission link 331 has two ends that pass through the two connecting plates 510, and each transmission link 331 has a positioning component at both ends. The positioning structure is used to prevent the transmission link 331 from detaching from the connecting plate 510.

[0062] With the above structure, the frame 500 consists of two connecting plates 510 and two side plates 520, which are arranged at intervals and facing each other. The side plates 520 are located between the connecting plates 510, forming a frame 500 by connecting them end to end, ensuring the stability and structural integrity of the frame 500. Both ends of each transmission link 331 pass through the connecting plate 510 and are provided with positioning components to prevent the transmission link 331 from detaching from the connecting plate 510, ensuring the stability of the position of the transmission link 331 and maintaining a good connection with the connecting plate 510. This helps to ensure that the transmission link 331 does not detach from the connecting plate 510 during movement, thus guaranteeing the reliability and stability of the rhythmic base frame.

[0063] Specifically, refer to Figure 1 and Figure 2 In this embodiment of the invention, the transmission connecting rod 331 has a second threaded portion and a third threaded portion. The positioning assembly includes a first positioning nut 440 and a second positioning nut 450. The first positioning nut 440 and the second positioning nut 450 are sequentially sleeved on the transmission connecting rod 331. The first positioning nut 440 is threadedly connected to the second threaded portion, and the second positioning nut 450 is threadedly connected to the third threaded portion. The first positioning nut 440 and the second positioning nut 450 are respectively located on opposite sides of the connecting plate 510. With the above structure, by threading the first positioning nut 440 and the second positioning nut 450 to both ends of the transmission connecting rod 331, the position of the transmission connecting rod 331 on the connecting plate 510 can be ensured to be stable. Furthermore, it allows for convenient installation and disassembly, improving the reliability and ease of use of the rhythmic base frame.

[0064] It should be noted that in this embodiment, the transmission link 331 is a screw. Of course, the transmission link 331 may also be partially provided with a first threaded portion, a second threaded portion and a third threaded portion, which is not limited here.

[0065] It is understood that in this embodiment of the invention, the electromagnetic coil body 310 has a square cross-sectional shape. The square cross-sectional shape allows for a lower thickness of the electromagnetic coil body 310 during manufacturing, which helps reduce the thickness of the electromagnetic drive mechanism 300, thereby further reducing the height of the rhythmic base frame in the spatial direction. This results in better mechanical strength and stability, and a more compact structure. It should also be noted that in this embodiment, the cross-sectional shapes of the aforementioned moving channel 311 and the two magnets 320 are both square, further reducing the thickness of the electromagnetic drive mechanism 300 during manufacturing.

[0066] Understandably, referring to Figure 1 and Figure 3 In this embodiment of the invention, the electromagnetic rhythmic base also includes a guide mechanism 600. One end of the guide mechanism 600 is connected to the fixed frame 100, and the other end is connected to the movable frame 200. The guide mechanism 600 guides the movable frame 200 to move relative to the fixed frame 100. With this structure, the guide mechanism 600 guides the relative movement of the fixed frame 100 and the movable frame 200 in the electromagnetic rhythmic base, thereby ensuring the stability and accuracy of the rhythmic base.

[0067] Specifically, refer to Figure 1 and Figure 3 In this embodiment, the guiding mechanism 600 includes a guiding elastic plate 610, a first fixing unit, and a second fixing unit. The first fixing unit includes a first fixing member 621, a first pressing member 622, and a first connecting structure. One end of the guiding elastic plate 610 is sandwiched between the first fixing member 621 and the first pressing member 622, and one end of the guiding elastic plate 610, the first fixing member 621, and the first pressing member 622 are fixedly connected to the fixing frame 100 through the first connecting structure. The second fixing unit includes a second fixing member 631 and a second pressing member 632. The second connecting structure is used to sandwich the other end of the guide elastic plate 610 between the second fixing member 631 and the second pressing member 632. The other end of the guide elastic plate 610, the second fixing member 631 and the second pressing member 632 are fixedly connected to the movable frame 200 through the second connecting structure. The first fixing member 621 is provided with a first limiting concave surface 6211, and the second fixing member 631 is provided with a second limiting concave surface 6311. The widths of both the first limiting concave surface 6211 and the second limiting concave surface 6311 are adapted to the width of the guide elastic plate 610.

[0068] Through the above structure, the guide elastic plate 610 can move with the movable frame 200 and can undergo elastic deformation. The deformation direction of the guide elastic plate 610 is consistent with the movement direction of the movable frame 200. When the movable frame 200 and the fixed frame 100 move relative to each other, the force exerted by the movable frame 200 on the guide elastic plate 610 is perpendicular to the surface of the guide elastic plate 610. The structure of the guide elastic plate 610 itself limits the movement direction of the movable frame 200, which helps to prevent the movable frame 200 from deviating from the movement direction, that is, to prevent the movable frame 200 from shaking due to deviation from the movement direction, thereby improving the stability of the rhythmic base frame during rhythmic movement. It improves user comfort, while having a simple structure, low cost, and long service life. Secondly, through the first limiting concave surface 6211 of the first fixing member 621 and the second limiting concave surface 6311 of the second fixing member 631, the widths of both the first limiting concave surface 6211 and the second limiting concave surface 6311 are adapted to the width of the guide elastic plate 610. That is, both the first limiting concave surface 6211 and the second limiting concave surface 6311 abut against the guide elastic plate 610, which helps to prevent the guide elastic plate 610 from swaying relative to the fixed frame 100 and the movable frame 200 in the width direction of the guide elastic plate 610, thereby improving the stability of the structure.

[0069] Of course, the above-mentioned guiding mechanism 600 is not limited to the guiding direction of the guiding elastic plate 610. In some embodiments, the guiding mechanism 600 may also include a first guide seat, a second guide seat and a ball bearing. The first guide seat is connected to the fixed frame 100, and the second guide seat is connected to the movable frame 200. A guiding channel is formed between the first guide seat and the second guide seat. The ball bearing is rotatably disposed in the guiding channel and in contact with it.

[0070] It should be noted that both the first and second connection structures mentioned above include connecting bolts and connecting nuts, which are simple in structure and easy to disassemble and maintain; the first fixing unit is fixedly engaged with the upper part of the fixing frame 100, and the second fixing unit is fixedly engaged with the lower part of the movable frame 200.

[0071] Understandably, referring to Figure 1 and Figure 4 In this embodiment of the utility model, the fixed frame 100 is provided with a first magnetic module 700 at both ends, and the movable frame 200 is provided with a second magnetic module 800 at both ends. The first magnetic module 700 and the second magnetic module 800 correspond to each other and are spaced apart. The magnetic poles at the opposite ends of the first magnetic module 700 and the second magnetic module 800 are the same.

[0072] By adopting the above settings, the relative movement between the fixed frame 100 and the movable frame 200 can be ensured to be within a certain range, avoiding movement exceeding the specified range, thereby ensuring the normal operation of the rhythmic base frame. This prevents excessive force transmission between the fixed frame 100 and the movable frame 200, prevents abnormal movement or collisions in unexpected situations, avoids the possibility of overload or damage, extends the service life of the rhythmic base frame, simplifies the operation process, reduces the technical requirements for operators, and improves the convenience and reliability of operation. Secondly, when the distance between the fixed frame 100 and the movable frame 200 reaches the limit value, due to the identical magnetic poles at the opposite ends of the first magnetic module 700 and the second magnetic module 800, the fixed frame 100 and the movable frame 200 will be obstructed, thus limiting further movement. Due to the repulsive force of identical magnetic poles, when the fixed frame 100 or the movable frame 200 approaches the limit position, the repulsive force increases, thereby generating an obstructive force that stops the movable frame 200 from moving. This helps to achieve precise position control, ensuring that the movable frame 200 stops at the required position.

[0073] Specifically, refer to Figure 1 and Figure 4 In this embodiment, the first magnetic module 700 includes a first mounting plate 710, two first magnetic pillars 720, and a first anti-collision block 730. The two first magnetic pillars 720 are spaced apart and connected to the first mounting plate 710, and the first anti-collision block 730 is connected to the first mounting plate 710 and located between the two first magnetic pillars 720. The second magnetic module 800 includes a second mounting plate 810, two second magnetic pillars 820, and a second anti-collision block 830. The two second magnetic pillars 820 are spaced apart and connected to the first mounting plate 710, and the second anti-collision block 830 is connected to the second mounting plate 810 and located between the two second magnetic pillars 820. The first magnetic pillars 720 and the second magnetic pillars 820 are correspondingly arranged, and the first anti-collision block 730 and the second anti-collision block 830 are correspondingly arranged, resulting in a compact structure that further increases the stability of the entire structure.

[0074] It should be noted that a first pad is provided between the first magnetic post 720 and the first mounting plate 710, and a second pad is provided between the second magnetic post 820 and the second mounting plate 810. The first pad and the second pad can be iron sheets or rubber parts; the first anti-collision block 730 and the second anti-collision block 830 mentioned above are both made of rubber parts or iron sheets.

[0075] It is understood that, in this embodiment of the invention, the cross-sectional shape of the moving channel 311 is one of a triangle, rectangle, polygon, ellipse, or curved surface, and the cross-sectional shapes of the two magnets 320 are adapted to the moving channel 311. This can be understood as referring to... Figure 1The shapes of the moving channel 311 and the magnet 320 are both rectangular; see reference. Figure 5 The shapes of the moving channel 311 and the magnet 320 are both polygonal, i.e., hexagonal, as shown in the reference. Figure 6 The shapes of the moving channel 311 and the magnet 320 are both concave. The aforementioned polygons can also be pentagons, pentagrams, hexagons, etc.; see reference. Figure 7 The aforementioned ellipse can be a shape where the distance from the center of the ellipse to each point on the curve is unequal, or an ellipse can be a shape where the distance from the center of the circle to any point on the circumference is equal; the aforementioned curved surface can be a U-shape or other shapes.
