Description
Technical Field
[0001] The invention belongs to the technical field of rocking chairs, and in particular relates to a support structure of an electric rocking chair. Background Art
[0002] As is known in the industry, the rocking chair support is the core component of the rocking chair. Since the early rocking chairs were rocked back and forth alternately by human power, it is necessary to keep the rocking chair swinging continuously by stepping on the ground or using reasonable body movements from time to time, otherwise the swing amplitude will gradually decrease and eventually stop. Electric rocking chairs can make up for the above shortcomings, and technical information on electric rocking chairs can be found in the public Chinese patent documents, such as CN109008365A recommends "a universal electric rocking chair base and rocking chair", CN112167864A "electric rocking device for sofa rocking chair", CN111387741A introduces "a single electric rocking chair", etc. A typical example is the "electric rocking chair bracket" disclosed in CN102669979B. This patent is proposed to address the shortcomings of CN201718813U (adjustable electric rocking chair) and CN102028600A (chair-type massage machine), and the technical solution provided by CN102669979B can objectively reflect the technical effects recorded in paragraph 0011 of the specification, but there are the following deficiencies: First, due to the use of a motor, worm and worm gear structure, and during operation, the motor drives the worm through a belt, and then the worm drives the worm wheel, and then the worm wheel shaft drives the movable sleeve through an eccentric wheel, and finally the connecting rod on the movable sleeve drives the cushion frame to swing, so this structure The structure is relatively complicated, which is not conducive to manufacturing and assembly on the one hand, and is not economical on the other hand. In addition to the high purchase price, it is not conducive to saving maintenance costs in daily use; secondly, due to the large number of power transmission links, it is not conducive to energy saving; thirdly, due to the lack of a reasonable pivot support connection between the seat bracket (called "cushion bracket" in the patent) and the base frame, the support strength of the seat bracket significantly suspended above the base frame is relatively large with only one connecting rod (also called "rocker"), and there is a risk of deformation during use; fourthly, due to the relatively unreasonable structure of the base frame, the mobility is poor when changing locations, and the reliable support effect during use is difficult to meet the expected requirements.

[0031] See also Figure 3 And combined with Figure 1 and Figure 2 ,exist Figure 3 The figure shows a rocking chair seat cushion 6, a rocking chair back cushion 7 and a leg rest pad 8 with good elasticity. Since the arrangement of the rocking chair seat cushion 6, the rocking chair back cushion 7 and the leg rest pad 8 on the aforementioned seat bracket 3 with a hollow frame structure belongs to the technical scope well known in the industry, the applicant will not describe it in detail.
[0032] The aforementioned electrical controller 25 is preferably wirelessly controlled by a remote controller, that is, the electrical controller 25 is electrically controlled by a manually operated remote controller. When the rocking chair is to be used, the user first sits on the aforementioned rocking chair seat cushion 6 and places his back against the rocking chair back cushion 7. By operating the remote controller, the electrical controller 25 operates the motor 21, the motor 21 drives the reduction box 22, the reduction box power output shaft 221 of the reduction box 22 drives the connecting rod connecting arm 23 with a crank arm effect, the connecting rod connecting arm 23 drives the connecting rod lower hinge 241 through the connecting rod connecting arm hinge shaft head 231, so that the connecting rod lower hinge 241 drives the connecting rod 24, and the connecting rod upper hinge 242 of the connecting rod 24 drives the seat bracket 3 through a pair of connecting rod hinge plates 31, so that the seat bracket 3 drives the user (leisure person) located on the rocking chair seat cushion 6 to swing with the seat bracket 3, and the swing frequency can be adjusted by the remote controller as needed. In the above process, since the user is located on the seat support 3, and since the seat support swing pivot support shaft 53 of the structural system of the seat support swing pivot support mechanism 5 is supported between the front beam pivot support seat 111 and the rear beam pivot support seat 121, under the action of gravity, the universal wheel shaft driving spring 43 of the structural system of the above four chassis rolling support mechanisms 4 is in a compressed state, and the universal wheel shaft 42 together with the universal wheel seat 44 and the universal wheel 45 are in an ascending position, that is, in a state of leaving the ground, and the entire weight is supported by a pair of chassis left support feet 131 and a pair of chassis right support feet 141, reflecting the stability in the use state. In the above process, each time the connecting rod connecting arm 23 completes a movement process, the connecting rod connecting arm signal collector 261 collects a signal, indicating that the rocking chair has rocked once. In the above process, since the seat frame swing pivot support mechanism 5 is pivotally matched with the base frame 1 through the front and rear beam pivot shaft support seats 111 and 121, the force on the connecting rod 24 is reduced to avoid deformation and affect the swing effect.
[0033] When the motor 21 is to be stopped, the user operates the remote control to stop the motor 21. When the motor 21 is stopped, the end surface of the connecting rod end of the front connecting rod connecting arm 23 corresponds to the connecting rod connecting arm signal collector 261, that is, the connecting rod connecting arm 23 is in the state of being Figure 1 When the user leaves the rocking chair seat 6, the universal wheel shaft 42 together with the universal wheel seat 44 and the universal wheel 45 are restored to the state of forming a rolling pair with the floor (the universal wheel 45 is in contact with the floor) under the restoring force of the universal wheel shaft actuating spring 43, so that the rocking chair can be moved to other places as needed.
[0034] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
