[0031] 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.

[0032] In related technologies, the rhythmic base frame usually consists of two frames. The movable frame 120 can be suspended on the fixed frame 110 and can move back and forth. The rhythmic effect is achieved by the back and forth movement of the movable frame 120 relative to the fixed frame 110.

[0033] It should be noted that the movable frame 120 is positioned above the fixed frame 110, forming a stacked structure. During actual handling, personnel typically lift the end of the movable frame 120 to perform the handling operation. At this time, due to gravity, the fixed frame 110 will shift relative to the movable frame 120, causing the distance between the two frames to gradually decrease, and they may even become completely flush.

[0034] This structural feature presents the following safety hazards: when the hands of the handler are located between the opposite sides of the two frames in the length direction, or between the upper surface of the fixed frame 110 and the lower surface of the movable frame 120 in the height direction, if the two frames move relative to each other and the ends in the length or height direction approach or even touch each other, it is very easy to cause the handler's hand to be pinched.

[0035] The following is combined Figures 1-3 This invention describes a suspended, limiting horizontal rhythmic base frame and rhythmic furniture. The rhythmic furniture includes the aforementioned suspended, limiting horizontal rhythmic base frame and a supporting body. The supporting body can move rhythmically relative to the suspended, limiting horizontal rhythmic base frame by reciprocating back and forth. It is understood that, in embodiments of this invention, the aforementioned rhythmic furniture can be a rhythmic chair, a rhythmic bed, etc.

[0036] Reference Figures 1 to 3 According to the present invention, a suspended limiting horizontal rhythmic base frame is provided, including a base frame mechanism 100 and an anti-pinch structure 200. The base frame mechanism 100 includes a fixed frame body 110, a movable frame body 120 and a connecting structure 130. One end of the connecting structure 130 is rotatably connected to the fixed frame body 110 and the other end is rotatably connected to the movable frame body 120. The movable frame body 120 is suspended on the fixed frame body 110 through the connecting structure 130, and the anti-pinch structure 200 is disposed between the fixed frame body 110 and the movable frame body 120. The anti-pinch structure 200 is used to limit the fixed frame body 110 and the movable frame body 120 to maintain a preset anti-pinch distance when they move relative to each other.

[0037] The suspended limiting horizontal rhythmic base frame provided by this utility model has an anti-pinch structure 200 on the fixed frame 110, so that the moving frame 120 always maintains a certain anti-pinch distance with the fixed frame 110 during the movement, effectively preventing pinching accidents during operation, improving the safety of equipment use, ensuring a safe distance, not affecting the normal relative movement of the frame, and maintaining the integrity of the rhythmic function of the equipment.

[0038] Reference Figures 1 to 3 In this embodiment, the movable frame 120 covers the fixed frame 110, and there is a gap between the two.

[0039] It is important to understand that, referring to Figure 1 and Figure 2In the embodiment of the utility model, the suspension limiting type horizontal pulsating chassis further comprises an electromagnet driving mechanism 400, the electromagnet driving mechanism 400 comprises a coil unit 410 and a magnetic unit 420, the fixed frame body 110 is connected with the coil unit 410, the movable frame body 120 is connected with the magnetic unit 420, and the magnetic power is generated through the magnetic field change between the coil unit 410 and the magnetic unit 420, so that the fixed frame body 110 and the movable frame body 120 relatively move.

[0040] By utilizing the electromagnetic induction principle, the motion control of the pulsating chassis height can be realized, not only the mechanical wear is reduced, the reliability and the life of the electromagnet driving mechanism 400 are improved, but also the noise is reduced, and the utility model is suitable for a variety of precision control application scenarios.

[0041] Of course, in some embodiments, the above-mentioned suspension limiting type horizontal pulsating chassis can also adopt an eccentric wheel driving mechanism, for example: the driving motor drives the movable frame body 120 to reciprocate forward and backward through the eccentric transmission of the transmission pulley and the eccentric wheel.

[0042] Referring to Figure 1 and Figure 2 In the embodiment of the utility model, the suspension limiting type horizontal pulsating chassis has a motion state and a static state, the motion state comprises a driving state and a non-driving state, in the driving state, the electromagnet driving mechanism drives the movable frame body 120 to move forward and backward, in the non-driving state, the movable frame body 120 and the fixed frame body 110 relatively move under the action of external force (non-driving force) through the setting of the connecting structure 130.

[0043] It should be noted that in the driving state, the movable frame body 120 does not contact the anti-pinch structure 200, that is, the movable frame body 120 does not impact the anti-pinch structure 200, which is beneficial to avoid noise.

[0044] Of course, in some embodiments, the movable frame body 120 and the anti-pinch structure 200 are in contact, and a damping structure (such as a rubber pad) can be arranged on at least one of the movable frame body 120 and the anti-pinch structure 200 to further reduce noise.

[0045] It can be understood that referring to Figure 1 and Figure 2In the embodiment of the utility model, the connecting structure 130 includes a connecting piece 131 and two sets of bearing units 132, one end of the connecting piece 131 is rotatably installed on the fixed frame body 110 through one set of bearing units 132, and the opposite end of the connecting piece 131 is rotatably installed on the movable frame body 120 through the other set of bearing units 132, so as to suspend the movable frame body 120 on the fixed frame body 110.

[0046] Of course, in some embodiments, the connecting structure 130 can also only include the connecting piece 131, and the two ends of the connecting piece 131 are rotatably connected with the fixed frame body 110 and the movable frame body 120 respectively.

[0047] It can be understood that, with reference to Figures 1 to 3 In the embodiment of the utility model, the anti-pinch structure 200 includes at least one anti-pinch plate 210, the anti-pinch plate 210 is arranged on the fixed frame body 110, the anti-pinch plate 210 is provided with a stop portion 211, and the stop portion 211 is arranged in a spaced manner with the movable frame body 120; wherein, when the fixed frame body 110 and the movable frame body 120 move relatively, the stop portion 211 abuts against the movable frame body 120 to form an anti-pinch distance between the movable frame body 120 and the fixed frame body 110.

[0048] It should be noted that the stop portion 211 is arranged in a spaced manner with the movable frame body 120, which is described in a static state. When the movable frame body 120 moves forward and backward relative to the fixed frame body 110, or when the fixed frame body 110 moves forward and backward relative to the movable frame body 120, the movable frame body 120 stops moving when it abuts against the stop portion 211, and maintains the anti-pinch distance with the fixed frame body 110, effectively avoiding the pinch injury accident caused by carrying and ensuring the safety of the carrier.

[0049] Specifically, with reference to Figures 1 to 3 In the embodiment of the utility model, the anti-pinch plate 210 is two, the two anti-pinch plates 210 are arranged at opposite ends of the length direction of the fixed frame body 110, and the two ends of the length direction of the movable frame body 120 are at least partially arranged between the stop portions 211 of the two anti-pinch plates 210.

[0050] By arranging the anti-pinch plate 210 at both ends of the fixed frame body 110, when lifting, the fixed frame body 110 and the movable frame body 120 move relatively, and can be stopped by the stop portion 211 of the anti-pinch plate 210 in both forward and backward directions, realizing bidirectional mechanical limiting.

[0051] Specifically, in the embodiment of the utility model, the stop portion 211 and the movable frame body 120 are at least partially structurally coincident in the height direction. The above structure makes the inner side surface of the stop portion 211 and the outer side surface of the end portion of the movable frame body 120 form mechanical abutment, which not only helps to limit the preset anti-pinch spacing when the movable frame body 120 and the fixed frame body 110 move relative to each other, but also, when the movable frame body 120 and the fixed frame body 110 move relative to each other, if one of the frame bodies has a tendency to overturn in the up-down direction, the inner side surface of the stop portion 211 and the outer side surface of the end portion of the movable frame body 120 form mechanical abutment, which limits the overturned frame body from stopping the overturning tendency, so as to ensure the necessary anti-pinch spacing and effectively prevent the pinching accident caused by the end portion of the frame body being attached.

[0052] Specifically, with reference to Figures 1 to 3 In the embodiment of the utility model, the stop portion 211 is a protruding structure. The above structure provides a clear contact point, which can increase the pressure of the contact surface, improve the limiting reliability, ensure the accuracy and consistency of the limiting action, optimize the structural strength, and improve the impact resistance and wear resistance, thereby prolonging the service life of the stop portion 211.

[0054] It should be noted that the limiting portion 212 is spaced apart from the movable frame body 120 in the static state.

[0055] Through the above arrangement, when the movable frame body 120 overturns downward during the relative movement of the movable frame body 120 and the fixed frame body 110, the limiting portion 212 abuts against the movable frame body 120, which limits the relative position between the movable frame body 120 and the fixed frame body 110, avoids the downward movement of the movable frame body 120 relative to the fixed frame body 110, and plays a certain supporting role; and the limiting portion 212 cooperates with the stop portion 211 to maintain the necessary anti-pinch spacing between the movable frame body 120 and the fixed frame body 110.

[0056] It can be understood that, in the embodiment of the utility model, the anti-pinch plate 210 forms the limiting portion 212 and the stop portion 211 connected with the limiting portion 212 by bending, and the limiting portion 212 and the stop portion 211 are formed by bending, which can realize the anti-pinch function without adding additional components, so that the structure is more compact, saves space, and reduces cost.

[0057] In the embodiment of the utility model, the anti-pinch plate 210 is detachably connected with the fixed frame body 110 through bolts, of course, the anti-pinch plate 210 can also be welded, clamped or connected with the fixed frame body 110, etc., the anti-pinch plate 210 is a metal plate, of course, in some embodiments, the anti-pinch plate 210 can also be made of other materials, such as plastic.

[0058] It should be noted that in some other embodiments, the anti-pinch structure 200 can also only include one anti-pinch column, the end of the anti-pinch column has a stop groove matched with the movable frame body 120, which still has the above-mentioned effect, which is not limited here.

[0059] Of course, in some embodiments, the anti-pinch structure 200 can also be arranged on the movable frame body 120, which is not limited here.

[0060] It can be understood that, referring to Figure 1 and Figure 2 In the embodiment of the utility model, the horizontal rhythmic chassis further comprises at least one extension frame 300, the extension frame 300 is fixedly connected with the fixed frame body 110, and at least part of the structure of the extension frame 300 protrudes along the length direction of the fixed frame body 110.
