Description

Technical Field

[0001] The invention mainly relates to the technical field of automobile seats, and in particular to a cockpit seat. Background Art

[0002] The rear seats of existing cars are generally set up as double seats or triple seats. The triple seats result in a smaller space for vibration reduction adjustment in the rear space of the car in the lateral direction for the vibration reduction structure, which cannot meet the lateral vibration reduction requirements of bumpy roads. In comparison, the double seat design can better meet the vibration reduction requirements of bumpy roads, but in non-bumpy roads, the lateral space of the rear seat of the car will be redundant, and the number of people that can be carried will be reduced.

[0003] The prior art CN117382504A has disclosed a deformable seat, comprising a first seat and a second seat, and the armrest mechanisms of the first seat and the second seat can be moved and / or folded to form a backrest mechanism and a cushion mechanism of a third seat, but the component disclosed therein for flipping the armrest mechanism is a single-rod rotating mechanism. Such a single-rod rotating mechanism in the prior art has only one rotating rod, and the two ends of the rotating rod are respectively connected to a flipping motor and an armrest bracket to be driven to flip, and one end of the rotating rod is fixed as a rotation axis, and the other end rotates around the fixed axis under the drive of the motor. This single-rod rotating mechanism with one end fixed and the other end movable has many defects in actual use: (1) The flip motor drives the rotating rod alone, and the simple structure means that the armrest mechanism cannot be locked when it is flipped and laid flat. The flip motor needs to provide a large locking force to keep the rotating rod in the current state and no longer rotate downward, resulting in high motor consumption and poor reliability. (2) When the armrest mechanism is in a vertical state, the passenger may lean on the armrest mechanism, causing the force on it to have a large torque in the horizontal direction. The flip motor still needs to provide a large locking force, resulting in high motor consumption and poor reliability.

[0004] Therefore, there is an urgent need for a cockpit seat with an armrest bracket structure that is more labor-saving and has a self-locking effect. Summary of the invention

[0028] DETAILED DESCRIPTION

[0029] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0030] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0032] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0033] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0034] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

[0035] It should be understood that when a component is referred to as being “on another component,” “connected to another component,” “coupled to another component,” or “contacting another component,” it can be directly on, connected to, coupled to, or contacting the other component, or intervening components may be present. In contrast, when a component is referred to as being “directly on another component,” “directly connected to,” “directly coupled to,” or “directly contacting” another component, there are no intervening components present.

[0036] Figure 1 is a three-dimensional schematic diagram of a cockpit seat 10 according to an embodiment of the present application. Figure 2 2 is an exploded perspective view of a movable side pad structure 200 according to an embodiment of the present application. Figure 1-5 As shown, this embodiment provides a cabin seat 10, including a support structure 100 and a movable side cushion structure 200, wherein the support structure 100 is equivalent to the main body of the seat, including a seat cushion support 110 and a back cushion support 120, which are connected, and the side edges adjacent to the seat cushion support 110 and the back cushion support 120 extend along the x direction. The movable side cushion structure 200 includes a side cushion support 210, a connecting assembly 220 and a driving assembly 230, and the side cushion support 210 is arranged on the side of the support structure 100 at an adjustable angle through the connecting assembly 220, and the side edges adjacent to the seat cushion support and the side cushion support 210 extend along the y direction. The x direction and the y direction are located in a horizontal plane, and the z direction is perpendicular to the horizontal plane.

[0037] The movable side pad structure 200 in the cabin seat 10 provided in this embodiment can be used as an armrest, and the side pad bracket 210 is installed on the side of the seat cushion bracket and is perpendicular to the seat cushion bracket 110. Under the action of the driving component 230 and the connecting component 220, the side pad bracket 210 can rotate around the Y direction and be used as a seat cushion when it is rotated downward and laid flat.

[0038] Specifically, refer to Figure 2 , Figure 3A and Figure 3BAs shown, the side cushion bracket 210 has a mounting cavity 211 ( Figure 3A and 3B The outer wall of the installation cavity 211 is removed from the installation cavity 211, the installation cavity 211 extends in the direction of the cushion bracket, and the installation cavity 211 has a screw rod 212 inside, the surface of the screw rod 212 has threads and extends along the extension direction of the installation cavity 211. The connecting assembly 220 includes a first rod body 221 and a second rod body 222 connected in sequence, one end of the first rod body 221 is connected to the cushion bracket, and the other end (that is, the end of the first rod body 221 away from the cushion bracket) is connected to the second rod body 222. It should be noted that the second rod body 222 and the first rod body 221 are fixedly connected, and the two will not rotate.

[0039] Further, the second rod 222 has a first end 223 close to the first rod 221 (i.e., an end suitable for connecting with the first rod 221) and a second end 224 away from the first rod 221. The first end 223 of the second rod 222 has a hinge point 225, and the side pad bracket 210 is suitable for being hinged to the second rod 222 through the hinge point 225. The side pad bracket 210 can also be hinged to the first rod 221 through the hinge point 225. It should be noted that this hinge is not completely fixed, but rotatable. The side pad bracket 210 is suitable for rotating around the hinge point 225, and during this process, the first rod 221 and the second rod 222 do not rotate or move.

[0040] Furthermore, the second end 224 of the second rod body 222 is rotatably connected to the screw rod 212. It is understandable that the screw rod 212 is disposed on the side pad bracket 210, and does not move relative to the side pad bracket 210, so the screw rod moves with the side pad bracket 210. The driving assembly 230 is fixed to the side pad bracket, and has a nut 233 that is transmission-connected to the screw rod, and is suitable for driving the nut 233 to move relative to the screw rod 212, so that the screw rod 212 rotates around the second end 224 of the second rod body 222, and the side pad bracket 210 rotates around the hinge point 225, and the process will be described later.

[0041] In such FIG. 3A to FIG. 8 In the illustrated embodiment, the cabin seat 10 has a first configuration and a second configuration. In the first configuration, the movable side cushion structure 200 is used as an armrest of the seat where the support structure 100 is located, and the side cushion support 210 is perpendicular to the seat cushion support 110, such as Figure 3A In the second configuration, the movable side cushion structure 200 is laid flat to be used as another separate seat cushion, and the side cushion bracket 210 is parallel to the seat cushion bracket 110 (or the two are located on the same surface), as shown in FIG. Figure 5The driving assembly 230 is adapted to drive the side pad bracket 210 to rotate around the y direction through the connecting assembly 220 to switch between the first form and the second form.

[0042] In this preferred embodiment, the driving assembly 230 includes a turbine motor 231 and a housing 232 connected to each other. The housing 232 has a nut 233 inside. The nut 233 is connected to the turbine motor 231 and is suitable for rotating under the drive of the turbine motor 231. Further, the threads of the nut 233 and the screw rod 212 are matched. When the turbine motor 231 drives the nut 233 to rotate, the threads of the nut 233 and the screw rod 212 are engaged and generate relative motion. The nut 233 moves along the direction in which the screw rod 212 extends, thereby driving the entire driving assembly 230 to move along the screw rod 212.

[0043] Specifically, in the first state, the driving assembly 230 is close to the second rod body 222, and the screw rod 212 extends along the z direction. Figure 3A , Figure 6 When the driving assembly 230 is in motion, the nut 233 moves upward along the screw rod 212, so that the entire driving assembly 230 and the side pad bracket 210 in which it is located also move upward along the screw rod 212. Since the side pad bracket 210 is fixed on the hinge point, the side pad bracket 210 also moves upward along the screw rod 212, which will force the screw rod 212 to rotate around the second end 224 of the second rod body 222, and the side pad bracket 210 rotates around the hinge point 225, as shown in FIG. Figure 4 , Figure 7 As shown. Finally, the side pad bracket 210 reaches the second state. In the second state, the driving assembly 230 is away from the second rod body 222, and the screw rod 212 extends along the x direction, as shown. Figure 6 , Figure 8 shown.

[0044] Furthermore, in order to prevent the driving assembly 230 from moving unrestricted on the screw rod 212 and causing the side pad bracket 210 to rotate too much, in this preferred embodiment, the screw rod 212 is away from the end of the second rod body 222 (i.e., Figure 3B When the drive assembly 230 moves along the screw rod 212 and gradually moves away from the second rod body 222 until the side cushion bracket 210 reaches the second state, that is, the side cushion bracket 210 is flat and parallel to the seat cushion bracket, the housing 232 of the drive assembly 230 abuts against the sleeve 214 along the x direction to play a role in limiting the position, as shown in FIG. Figure 3B shown.

[0045] In this application Figure 1-8In the illustrated embodiment, the first rod 221 extends outward from the side of the cushion bracket along the x direction, while the second rod 222 does not extend along the x direction, but has an angle with the first rod 221. Specifically, the second end 224 of the second rod 222 is higher than the first end 223 in the z direction, and the second end 224 is closer to the cushion bracket than the first end 223 in the x direction. In other words, the second rod 222 is tilted upward and points in the direction of the cushion bracket. Further, in this preferred embodiment, there is an angle α between the second rod 222 and the horizontal plane where the x direction and the y direction are located. For example, α is an acute angle, such as 45°. This setting can make it possible for the first rod 221 and the second rod 222 to play a certain supporting role in the z direction for the horizontal side cushion bracket 210 when the side cushion bracket 210 is in the second form, saving the force required to be provided by the turbine motor 231 and saving power.

[0046] Furthermore, in some embodiments, the upper surface of the first rod body 221 further has a support surface 226. In the first state, the support surface 226 can abut against the side pad bracket 210 along the z direction. This arrangement can make the cabin seat 10 have a certain self-locking effect in the first state, and the turbine motor 231 only needs to provide a locking force, which can also save power.

[0047] refer to Figure 2 As shown, in one embodiment of the present invention, the connecting assembly 220 further includes another first rod 221', the other first rod 221' is fixed on the cushion bracket, and the other first rod 221' and the first rod 221 are fixedly connected by at least one transmission rod 240. In this embodiment, the two first rods 221, 221' and the transmission rod 240 are assembled. In some other embodiments, the number of the transmission rods 240 can be more, and the first rods 221, 221' and the transmission rod 240 can also be integrally formed instead of being assembled later, and the present application does not make any specific restrictions here.

[0048] Furthermore, in one embodiment of the present invention, the cabin seat 10 further comprises a slide rail 300, which is arranged on the side of the seat cushion bracket 110 and the back cushion bracket 120, and the movable side cushion structure 200 is slidably arranged on the slide rail 300. The side cushion bracket 210 is connected to the slide rail 300 through the connecting assembly 220, and when the movable side cushion structure 200 rises along the slide rail 300 to the side of the back cushion bracket 120, the side cushion bracket 210 can be rotated to become another back cushion for use.

[0049] exist Fig. 9 In another embodiment shown, the cabin seat 10 does not include a slide rail. The movable side pad structure 200 is directly disposed on the seat cushion bracket 110 and is used as a seat cushion when it is laid flat. Other details of this embodiment can be referred to the previous embodiment and will not be expanded here.

[0050] It can be understood that when the adjacent sides of two adjacent cabin seats 10 are both installed with movable side pad structures 200, the two movable side pad structures 200 can be used as a seat cushion and a back cushion respectively, thereby forming a third seat.
