Description

Technical Field

[0001] The utility model relates to the field of automobile seats, in particular to a swing bracket and a follow-up driving device. Background Art

[0002] Chinese invention patent publication number CN114013350B discloses a seat adjustment mechanism primarily driven by a motor rotatably fixed to the side of the seat frame via a cage-like bracket. Because the cage-like bracket is fixed to the frame, and the motor can only rotate relative to the cage-like bracket, the adjustment mechanism has limited swing space during operation due to the cage-like bracket's internal space. Furthermore, because the entire follower drive device 100 (including the motor) is mounted perpendicular to the frame's side plate 300, the soft synchronous shaft 200 bends after being connected to the follower drive device 100, affecting the transmission efficiency of the synchronous shaft 200. Utility Model Content

The second part is connected to the seat frame via a rotating shaft so that the swing bracket rotates relative to the seat frame with the rotating shaft as the rotation center.

[0005] Furthermore, the connecting surface of the second part is passed through by the rotating shaft and is tightly connected to the seat frame, and the connecting surface is inclined relative to the installation direction of the driving mechanism.

[0006] Furthermore, the tilt refers to a non-vertical angle between the connecting surface and the installation axis of the driving mechanism.

Longitudinal (X direction)", "lateral (Y direction)" and "vertical (Z direction)" are terms used in the automotive field as spatial coordinate systems, and are professional terms well known to those skilled in the art. The above description is intended to simplify the description of the present invention, and does not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0031] The singular forms "a", "an", "said" and "the" used in the specification include plural forms unless otherwise indicated. The terms "include", "comprises" and "comprising" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0032] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” “engaged to,” or the like, the element may be directly on, fixed to, connected to, engaged to, or contacting the other element, or intervening elements may be present.

[0033] It will be understood that although the terms "first," "second," etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the present invention.

[0034] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments. In all figures, the same reference numerals represent the same elements or elements with the same function.

[0035] refer to Figure 2 In the overall structure shown, the drive mechanism 101 is fixed to the swing bracket 130. The swing bracket 130 and the screw rod 121 in the drive mechanism 101 are both connected to the side plate 300 of the backrest frame via a rotating shaft 302b. The driving shaft 302b passes through the slide 301 and connects the screw rod 121 to the upper portion of the backrest. When the screw rod 121 moves under the drive of the motor component 110, the upper portion of the backrest rotates, and the swing bracket 130 synchronously and adaptively swings.

[0036] refer to Figures 3 to 5 The swing bracket 130 is composed of a first portion 140 for fixing the drive mechanism 101 and a second portion 150 for connecting to the side plate 300. The first portion 140 is provided with a receiving hole 142. Since the power transmission of the drive mechanism 101 is achieved through the transmission box 120 arranged on one side thereof, the shape and structure of the receiving hole 142 are designed to be similar to the outer contour of the transmission box 120, so that the transmission box 120 can be directly inserted into the receiving hole 142 and prevented from falling out by a stopper 102 fixed to the back side. In addition, the drive mechanism 101 can also be fixed to the first portion 140 by screws, bolts, glue, or other known fastening methods. A pair of screw rod mounting holes 141 are also provided in the first portion 140. The screw rod mounting holes 141 are respectively arranged coaxially on both sides of the receiving hole 142 so that the screw rod 121 extending from the swing bracket 130 can be installed after the transmission box 120 is installed.

[0037] The second part 150 has a connecting surface 151 for connecting with the side plate 300. The connecting surface 151 is inclined relative to the installation axis of the transmission box 120, so that the drive mechanism 101 with the transmission box 120 can be installed at an angle α relative to the side plate 300. In this way, the soft synchronous shaft 200 arranged between the two side follower drive devices 100 can maintain a vertical connection with the two side drive mechanisms 101 ( Figure 6) under the premise of being in a smooth arc, so as to avoid failure phenomena such as a sense of powerlessness in transmission and failure to start the driving mechanism 101 caused by repeated bending. Preferably, the angle α is any angle between 0 and 90 degrees.

[0038] A rotating hole 152 is also provided on the connecting surface 151, and the rotating shaft 302a passes through the side plate 300 and is connected to the rotating hole 152, so that the follower drive device 100 composed of the swing bracket 130 and the driving mechanism 101 slides in the slide groove 301 as a whole following the driving rotating shaft 302b and adaptively rotates on the inner side of the side plate 300 with the rotating shaft 302a as the axis. Therefore, its swing angle β is much larger than the swing amplitude of the cage-shaped bracket in the prior art, leaving more redundant space for the arrangement of other mechanisms such as the skeleton.

[0039] Figure 7 As shown, the driving mechanism 101 can be an active driving mechanism including a motor component 110 as a power source, or a passive driving mechanism driven by the synchronous shaft 200 through the transmission box 120 .

[0040] Preferably, the connecting surface 151, the slide groove 301 and the swinging surface of the screw rod 121 (i.e., the plane swept by the screw rod 121 when it swings) are parallel to each other, the rotating shaft 302b is perpendicular to the swinging surface of the side plate 300 and the screw rod 121 respectively, and the rotating shaft 302a and the rotating shaft 302b are parallel to each other.

[0041] Figure 8 and Figure 9 Two driving mechanisms with different structures are shown. Since the fixation between the swing bracket 130 and the driving mechanism 101 depends on the contour matching between the accommodating hole 142 and the transmission box 120, when the driving mechanism 101 serves as an active driving mechanism, the transmission box 120 and the motor component 110 can be perpendicular to each other or arranged horizontally and parallel.

[0042] In addition, the swing bracket 130 can also be designed with the first part 140 and the second part 150 as separate structures, and the second part 150 is fixed to the first part 140 through a supporting plate 153 extending laterally.

[0043] refer to Figure 10 In the first embodiment shown, a through hole 155 is formed on the support plate 153, and a first groove 143 is formed on the bottom of the first portion 140. Specifically, first ridges 154 extending toward each other are provided on a pair of opposing sides of the through hole 155, and the first grooves 143 are correspondingly provided on opposing side surfaces of the first portion 140. The first ridges 154 and the first grooves 143 are mated and engaged with each other to achieve the fixation of the first portion 140 and the second portion 150.

[0044] refer to Figure 11In the second embodiment shown, second ridges 156 are arranged on the opposite edges of the support plate 153, and a pair of downwardly extending protruding structures 144 are provided at the bottom of the second part 150. A pair of second grooves 145 are arranged opposite to each other on the inner sides of the pair of protruding structures 144, and the first part 140 and the second part 150 are fixed by matching and engaging the second ridges 156 with the second grooves 145.
