Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile seat, specifically to automobile seat and vehicle with it. BACKGROUND

[0002] With the continuous development of intelligent cockpit technology, the prior art has developed an automobile seat with zero gravity function. The design inspiration of this automobile seat comes from the seat of astronauts in space environment. Through the innovative design of ergonomics, the passenger can feel less pressure on the seat than his own gravity, thereby creating a floating weightlessness. Zero gravity seat can ensure the comfort of passengers, provide more suitable support for passengers, reduce local pressure points and reduce fatigue after long time sitting, which helps to reduce health problems caused by improper sitting posture.

[0003] On the automobile seat with zero gravity function, ABTS safety belt system (i.e. All Belt Tether to Seat) is usually equipped, so that all fixed points of the safety belt system are installed on the automobile seat, so that the automobile seat can meet the regulatory requirements during actual adjustment. However, when the automobile seat is in zero gravity state, once the vehicle collides, this safety belt system still cannot avoid the serious diving (i.e. sliding forward and downward) of the passenger, which will cause the spine of the passenger to be impacted greatly, and easily cause serious injuries such as spinal fracture.

[0004] Therefore, there is a need in the art for a new technical solution to solve the above problems. UTILITY MODEL CONTENT

[0005] In order to solve or improve the technical problem of poor safety of the automobile seat with zero gravity function in the prior art to some extent, the utility model provides an automobile seat. The automobile seat comprises: a base; a cushion framework rotatably fixed on the base and having opposite normal position and zero gravity position; a driving mechanism for driving the cushion framework to convert between the normal position and the zero gravity position; and a connecting bracket comprising fixed holes and return holes spaced apart from each other, the fixed holes are provided with fasteners for fixedly connecting the driving mechanism and the base, and when the cushion framework is in the zero gravity position, the driving mechanism can force the connecting bracket to produce relative displacement with the fastener under external force, so that the fastener moves to the return hole to drive the cushion framework to return to the normal position.

[0006] Those skilled in the art will understand that the present invention relates to a car seat comprising a base, a seat cushion frame, a drive mechanism, and a connecting bracket. The base provides suitable installation space for components such as the seat cushion frame, drive mechanism, and connecting bracket. The seat cushion frame is rotatably fixed to the base and has a relative normal position and a zero-gravity position. The drive mechanism is used to drive the seat cushion frame to switch between the normal position and the zero-gravity position, thereby improving the ease of control of the car seat. The connecting bracket includes spaced-apart fixing holes and return holes. Fasteners are provided in the fixing holes for fixing the drive mechanism and the base together. When the seat cushion frame is in the zero-gravity position, if no collision occurs, the drive mechanism can adjust the angle of the seat cushion frame normally according to the passenger's actual needs, allowing it to switch between the normal position and the zero-gravity position. If a collision occurs, the drive mechanism can force relative displacement between the fasteners and the connecting bracket under external force, thereby moving the fasteners into the return holes, and thus quickly returning the entire seat cushion frame to the normal position, preventing severe slumping of the passenger and significantly improving the safety of the car seat.

[0007] In the preferred embodiment of the aforementioned car seat, a collapsible hole is provided between the fixing hole and the return hole, wherein the width of the collapsible hole is smaller than the diameter of the fastener. The collapsible hole allows the fastener to move smoothly and stably from the fixing hole to the return hole, ensuring reliable return. Furthermore, setting the width of the collapsible hole to be smaller than the diameter of the fastener not only allows for adjustment of the timing of the collapsible return through parameter design, but also utilizes the collapsible deformation of the connecting bracket when the fastener passes through the collapsible hole, thus providing a certain energy absorption effect.

[0008] In the preferred embodiment of the aforementioned car seat, the diameter of the return hole is larger than the diameter of the fastener. Setting the diameter of the return hole to be larger than the diameter of the fastener allows the fastener to smoothly enter the return hole after passing through the collapse hole, ensuring that the seat cushion frame returns to its proper position.

[0009] In the preferred embodiment of the aforementioned car seat, the connecting bracket is further provided with positioning holes spaced apart from the fixing hole, the return hole, and the collapse hole. The positioning holes facilitate precise positioning of the connecting bracket during processing and installation.

[0010] In the preferred embodiment of the aforementioned car seat, the connecting bracket is made of steel. Using steel of suitable strength to process the connecting bracket ensures that it possesses good mechanical properties.

[0011] In the preferred embodiment of the aforementioned automotive seat, the connecting bracket is manufactured using a stamping process. Using a stamping process for the connecting bracket improves production efficiency and dimensional accuracy, fully utilizes raw materials, and reduces production costs.

[0012] In the preferred technical scheme of the above automobile seat, the connecting bracket is fixedly connected with the driving mechanism through a welding process. The fixed connection of the connecting bracket and the driving mechanism through the welding process can ensure the connection strength, reduce the self weight, and ensure the structural strength and integrity.

[0013] In the preferred technical scheme of the above automobile seat, the automobile seat further comprises a slide rail, and the base is slidably fixed on the slide rail. The provision of the slide rail can facilitate the adjustment of the position of the base.

[0014] In the preferred technical scheme of the above automobile seat, the automobile seat further comprises a leg support which is extendably fixed on the cushion framework. The provision of the leg support can increase the leg support area and further improve the comfort of the automobile seat.

[0015] In order to solve or improve the technical problem of poor safety of the automobile seat with the zero-gravity function in the prior art to some extent, the utility model also provides a vehicle. The vehicle comprises the automobile seat of any one of the above. BRIEF DESCRIPTION OF DRAWINGS

[0027] In order to solve or improve the technical problem of poor safety of the car seat with zero gravity function in the prior art to some extent, the present application provides a car seat 100. The car seat 100 comprises: a base 110; a cushion framework 120 rotatably fixed on the base 110 and having opposite normal position and zero gravity position; a driving mechanism 140 for driving the cushion framework 120 to switch between the normal position and the zero gravity position; and a connecting support 150 comprising fixed holes 152 and reset holes 153 spaced apart from each other, a fastener 160 is arranged on the fixed hole 152 for fixedly connecting the driving mechanism 140 and the base 110, and when the cushion framework 120 is in the zero gravity position, the driving mechanism 140 can force the connecting support 150 to relatively displace with the fastener 160 under the action of external force, so that the fastener 160 moves to the reset hole 153 to drive the cushion framework 120 to reset to the normal position.

[0028] Figure 1 is a structural schematic view of an embodiment of the utility model automobile seat; Figure 2 is a structural schematic view of an embodiment of the utility model automobile seat base, cushion framework, driving mechanism and connecting support. As Figure 1 and Figure 2 Indicated, in one or more embodiments, the utility model automobile seat 100 includes base 110, cushion framework 120, driving mechanism 140 and connecting support 150 and other components. Among them, the base 110 provides suitable installation space for cushion framework 120, driving mechanism 140 and connecting support 150 and other components. The base 110 can be processed by suitable metal materials (such as stainless steel, etc.), so that it has good mechanical properties. The cushion framework 120 is rotatably arranged on the base 110. The driving mechanism 140 is connected with the base 110 through the connecting support 150. In addition, the driving mechanism 140 is connected with the cushion framework 120 to control the rotation angle of the cushion framework 120.

[0029] As Figure 1 and Figure 2 Indicated, in one or more embodiments, the utility model automobile seat 100 also includes slide rail 170, and the base 110 is slidably arranged on the slide rail 170. The slide rail 170 is suitable for being fixed on the floor (not shown in the figure) of the vehicle and extends substantially in the front-back direction. The setting of the slide rail 170 can conveniently adjust the front-back position of the base 110 on the floor to meet the differentiated needs of different passengers. The sliding mode between the base 110 and the slide rail 170 can be manual adjustment or electric adjustment.

[0030] As Figure 1 and Figure 2 Indicated, the cushion framework 120 has opposite normal positions. At this time, the angle between the cushion framework 120 and the horizontal plane is about 5°-10°. In addition, the cushion framework 120 also has a zero-gravity position (not shown in the figure) opposite to the normal position. Correspondingly, the angle between the cushion framework 120 and the horizontal plane can be 30° or other suitable angles. Based on Figure 2 Indicated, the cushion framework 120 along the cushion framework 120 can support the hips and legs of the passenger, which helps the passenger to maintain the correct sitting posture, limits the body sway of the passenger, and improves the stability and safety of the ride. The cushion framework 120 can be processed by suitable metal materials (such as stainless steel, etc.), so that it has good mechanical properties.

[0031] As Figure 1As shown in the one or more embodiments, the utility model automobile seat 100 further comprises a backrest framework 130 rotatably fixed on the base 110. The backrest framework 130 can provide necessary support for the upper body of the passenger, help the passenger maintain correct sitting posture when riding, reduce body sway caused by inertia, and improve the comfort and safety of riding. The backrest framework 130 can be processed by a suitable metal material (such as stainless steel, etc.), so that it has good mechanical properties. In addition, the backrest framework 130 can also adjust the inclination angle through a suitable driving component (not identified in the figure) to switch between the normal position and the zero-gravity position. When the backrest framework 130 is in the normal position, the angle between the backrest framework 130 and the horizontal plane is about 100°. Correspondingly, when the backrest framework 130 is in the zero-gravity position, the angle between the backrest framework 130 and the horizontal plane is about 110°-135°.

[0032] As shown in the one or more embodiments, Figure 1 and Figure 2 As shown in the one or more embodiments, the utility model automobile seat 100 further comprises a leg rest 180. Based on the orientation shown, Figure 2 the leg rest 180 is arranged on the front side of the cushion framework 120. The leg rest 180 can be controlled by a suitable driving component (not identified in the figure) to expand forward to increase the leg support area and further improve the comfort of riding.

[0033] As shown in the one or more embodiments, Figures 1-2 the driving mechanism 140 is arranged on the right side of the base 110. That is, the driving mechanism 140 is connected to the right side frame of the base 110 through the connecting bracket 150. Alternatively, the driving mechanism 140 can also be arranged on the left side of the base 110. That is, the driving mechanism 140 is connected to the left side frame of the base 110 through the connecting bracket 150.

[0034] Figure 3 is a structural schematic view of an embodiment of the base, driving mechanism and connecting bracket in the utility model automobile seat. As shown in the one or more embodiments, Figure 3 the driving mechanism 140 comprises a driving motor 141, a lead screw 142, a sleeve 143 and a fixed bracket 144. Among them, the output shaft of the driving motor 141 is connected with the lead screw 142; the lead screw 142 is arranged in the sleeve 143; the sleeve 143 is fixedly connected with the fixed bracket 144. In addition, the driving motor 141 is connected with the cushion framework 120 through a connecting rod mechanism (not identified in the figure), and the fixed bracket 144 is fixedly connected with the connecting bracket 150. Through the above arrangement, when the driving motor 141 rotates forward or reversely, the lead screw 142 will rotate forward or reversely around the sleeve 143, and then drive the connecting rod mechanism to move, realizing the rotation of the cushion framework 120 between the normal position and the zero-gravity position.

[0035] Figure 4 is a structural schematic view of an embodiment of the connecting bracket and fastener in the automobile seat of the utility model; Figure 5 is a structural schematic view of an embodiment of the connecting bracket in the automobile seat of the utility model. As shown in Figure 4 and Figure 5 shown, in one or more embodiments, the connecting bracket 150 has a generally rectangular and rounded corner connecting bracket body 151. The connecting bracket body 151 can be processed by a suitable metal material, so that it has good mechanical properties, such as steel and the like. Preferably, the connecting bracket body 151 is processed by high-strength steel, so that it has strong rigidity and strength. In one or more embodiments, the connecting bracket 150 is processed by a stamping process, so as to improve production efficiency and dimensional accuracy, make full use of production raw materials, and reduce production cost. The connecting bracket 150 is connected with the driving mechanism 140. Specifically, the connecting bracket 150 is fixedly connected with the fixed bracket 144 in the driving mechanism 140. In one or more embodiments, the connecting bracket 150 is connected with the fixed bracket 144 by a welding process, so as to ensure the connection strength, reduce the self-weight, ensure the structural strength and integrity.

[0036] As shown in Figure 4 and Figure 5 , the fixed hole 152 and the reset hole 153 are formed on the connecting bracket body 151. Based on the orientation shown in 4, the fixed hole 152 is located on the front side of the connecting bracket body 151, and the reset hole 153 is located on the rear side of the connecting bracket body 151. The fixed hole 152 and the reset hole 153 have a generally circular shape. In the assembled state, the fastener 160 is arranged in the fixed hole 152, so as to fix the connecting bracket body 151 on the base 110. The fastener 160 can be but not limited to a cylindrical head inner hexagonal screw. Through the above arrangement, the driving mechanism 140 can be fixedly connected with the base 110 through the connecting bracket 150, and then the angle of the cushion framework 120 is conveniently adjusted under the control of the driving mechanism 140, so that it rotates between the working position and the zero-gravity position. At the same time, when the cushion framework 120 is in the zero-gravity position, the driving mechanism 140 can also force the connecting bracket 150 to produce relative displacement with the fastener 160 under the action of external force. Based on Figure 4 shown, the fastener 160 is fixedly connected with the base 110, the connecting bracket 150 moves forward relative to the fastener 160, so that the fastener 160 moves to the reset hole 153, so as to drive the cushion framework 120 to quickly reset to the normal position, prevent the passenger from serious diving, and significantly improve the safety of the automobile seat 100.

[0037] As shown in Figure 4 and Figure 5As shown, in one or more embodiments, a collapse hole 154 is arranged between the fixing hole 152 and the reset hole 153. Based on the arrangement Figure 4 As shown, the collapse hole 154 extends approximately in the front-rear direction. The arrangement of the collapse hole 154 can make the fastener 160 move smoothly and stably from the fixing hole 152 to the reset hole 153, ensuring the reliability of the reset. Further, the diameter of the fastener 160 is d, while the width of the collapse hole 154 is W (see Figure 5 ), and the width W of the collapse hole 154 is smaller than the diameter d of the fastener 160. In this way, not only can the timing of the collapse reset be adjusted by parameter design, but also the collapse deformation of the connecting bracket 150 can be caused by the fastener 160 passing through the collapse hole 154, playing a certain energy absorption role. Further, the diameter of the fixing hole 152 is D1, and the diameter D1 of the fixing hole 152 is slightly larger than the diameter d of the fastener 160, so that the fastener 160 can be conveniently fixed in the fixing hole 152. In one or more embodiments, the diameter of the reset hole 153 is D2, and the diameter D2 of the reset hole 153 is greater than the diameter d of the fastener 160, so that the fastener 160 can smoothly enter the reset hole 153 after passing through the collapse hole 154, ensuring that the cushion framework 120 is reset in place.

[0038] As shown in ​ and ​ in one or more embodiments, the connecting bracket body 151 is also provided with a positioning hole 155 spaced from the fixing hole 152, the reset hole 153 and the collapse hole 154. The arrangement of the positioning hole 155 not only facilitates the positioning of the connecting bracket body 151 during stamping processing, but also helps the positioning of the connecting bracket 150 during welding connection with the fixing bracket 144, thereby improving the processing and installation precision. In one or more embodiments, two positioning holes 155 are arranged on the left side of the connecting bracket body 151 and spaced from each other in the up-down direction. Alternatively, the number and arrangement position of the positioning hole 155 can also be adjusted according to actual needs.

[0039] In one or more embodiments, the utility model also provides a vehicle (not shown in the figure). The vehicle includes the car seat 100 described in any of the above embodiments.

[0040] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to related technical features without departing from the principles of the utility model, and the technical scheme after these changes or replacements will fall within the protection scope of the utility model.
