Technical Field

[0001] The utility model relates to the field of home furnishing manufacturing, and particularly relates to a silent intelligent electromagnetic drive mechanism. Background Art

[0002] There is a Chinese utility model patent with the application number 2024216862854 and the name of "An Intelligent Electromagnetic Drive Rocking Mechanism and a Rocking Chair Using the Mechanism", which discloses using a guide seat to guide a boosting rod, and the guide seat is a linear bearing purchased in the market. Since the balls in the linear bearing and the telescopic mandrel are both made of metal, during the working process, the noise generated by their mutual friction is relatively large, thus reducing the user experience and affecting the product quality. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a silent intelligent electromagnetic drive mechanism that improves the user experience and product quality.

[0004] To achieve the above purpose, the technical solution adopted by the silent intelligent electromagnetic drive mechanism of the utility model is:

[0005] A silent intelligent electromagnetic drive mechanism includes a bottom plate. On one side of the bottom plate, there is a guide seat, and on the other side, there is a variable-direction electromagnet. The guide seat penetrates through a boosting rod, and a permanent magnet cooperating with the variable-direction electromagnet is arranged at one end of the boosting rod. The guide seat is fixedly connected to the bottom plate through a base. The guide seat includes a tube body, and at both ends of the tube body, there are pivotally connected a number of rolling bearings for clamping the boosting rod, and a rubber ring is sleeved on the outer ring of the rolling bearing.

[0006] Preferably, the two end faces on both sides of the inner ring of the rolling bearing respectively protrude from the two end faces on both sides of the outer ring of the rolling bearing, and the two end faces of the rubber ring are flush with the two end faces on both sides of the outer ring of the rolling bearing.

[0007] Preferably, the rubber ring is made of PU material.

[0008] Preferably, the tube body includes a sleeve. At both ends of the sleeve, there are a number of first grooves for inserting pin shafts. In the middle of the sleeve at the position of the first grooves, there is a second groove for avoiding the rolling bearing. At both ends of the sleeve, there are bolt-connected pressure plates. In the middle of the pressure plate, there is a first avoidance hole for avoiding the boosting rod. At the edge of the first avoidance hole, there are second avoidance holes corresponding to the second grooves one by one, and the second avoidance holes are used for avoiding the rolling bearing.

[0009] Preferably, the outer peripheral surface of the sleeve is provided with four positioning grooves. The four positioning grooves are evenly circumferentially distributed around the axis of the sleeve. On the left and right sides of the base, there are positioning bosses cooperating with the positioning grooves. Between adjacent positioning grooves, there are rib plates, and at least one rib plate is provided with a bolt through-hole for connecting the positioning bosses.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The rubber ring isolates the booster rod and the rolling bearing, both of which are made of metal, so as to reduce the noise generated during the operation of the booster rod, and improve the user experience and product quality.

[0012] 2. The two end faces on both sides of the inner ring of the rolling bearing protrude from the two end faces on both sides of the outer ring of the rolling bearing respectively, avoiding the wear of the two end faces on both sides of the outer ring of the rolling bearing and the rubber ring. This can not only improve the service life of the entire guide seat, but also ensure the smoothness of the booster rod sliding in the guide seat. At the same time, since the two end faces on both sides of the outer ring of the bearing and the rubber ring are not worn, it is beneficial to improve the sound insulation effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further clarifies the utility model in conjunction with the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and not to limit the scope of the utility model. After reading the utility model, various equivalent forms of modification of the utility model by those skilled in the art all fall within the scope defined by the appended claims of this application.

[0021] As Figure 1-6As shown in the figure, a silent intelligent electromagnetic drive mechanism includes a base plate 1. A base 2 is installed on the left side of the base plate. The base is an injection-molded part. A guide seat 3 is installed on the base. The guide seat penetrates through a boosting rod 4. A permanent magnet 41 is fixedly connected to the right end of the boosting rod. A variable-direction electromagnet 5 that cooperates with the permanent magnet is installed on the right side of the base plate. The guide seat includes a tube body 31. The tube body includes a sleeve 311. Four positioning grooves 3111 are formed on the outer peripheral surface of the sleeve. The four positioning grooves are evenly distributed around the axis of the sleeve in a circumferential manner. Positioning bosses 21 that cooperate with the positioning grooves are integrally formed on the left and right sides of the base. Rib plates 3112 are formed between adjacent positioning grooves. Two bolt through holes 3113 for connecting the positioning bosses are formed on two opposite rib plates. Threaded holes 22 corresponding to the bolt through holes one by one are formed on the top surface of the positioning bosses. The positioning grooves and the positioning bosses cooperate to accurately position the guide seat, which is convenient for improving the assembly efficiency. Four first grooves 3114 arranged in a cross shape are formed at both ends of the sleeve. Pin shafts 32 are installed in the first grooves. Rolling bearings 33 are sleeved on the outer sides of the pin shafts. A second groove 3115 for avoiding the rolling bearings is formed in the middle of the sleeve at the position of the first grooves. The two ends of the sleeve are connected to a pressing plate 312 by bolts. The pressing plate blocks the pin shafts from sliding in the first grooves. A first avoidance hole 3121 for avoiding the boosting rod is formed in the middle of the pressing plate. Second avoidance holes 3122 corresponding to the second grooves one by one are formed at the edges of the first avoidance hole. The second avoidance holes are used to avoid the rolling bearings. The rolling bearings are used to clamp the boosting rod. The two end faces of the inner ring 331 of the rolling bearing protrude from the two end faces of the outer ring 332 of the rolling bearing respectively. A rubber ring 333 is sleeved on the outer ring of the rolling bearing. The rubber ring is made of PU material. The two end faces of the rubber ring are flush with the two end faces of the outer ring of the rolling bearing. The two end faces of the inner ring of the rolling bearing protrude from the two end faces of the outer ring of the rolling bearing respectively, which can prevent the two end faces of the outer ring of the rolling bearing and the rubber ring from being worn. This can not only improve the service life of the entire guide seat, but also ensure the smoothness of the boosting rod sliding in the guide seat. At the same time, since the two end faces of the outer ring of the bearing and the rubber ring are not worn, it is beneficial to improve the silent effect.

[0022] The specific working process and principle of the present invention: When the variable-direction electromagnet is energized, when the polarities of the variable-direction electromagnet and the permanent magnet are the same, the boosting rod slides in the guide seat under the action of the repulsive force (like poles repel each other). At this time, the rubber ring isolates the boosting rod and the rolling bearing, both of which are made of metal, so that the noise generated during the operation of the boosting rod can be reduced, and the user experience and product quality can be improved.
