[0025] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0026] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0027] Furthermore, the vehicle involved in the embodiment of the present invention may be an internal combustion engine vehicle using an engine as a power source, a hybrid vehicle using an engine and an electric motor as a power source, an electric vehicle using an electric motor as a power source, or the like.

[0028] Figure 1 is a schematic structural diagram of a front seat of a vehicle according to an embodiment of the present invention, Figure 2 1 is a schematic diagram of the structure of a front seat of a vehicle with a child seat installed according to an embodiment of the present invention. Figure 1 and Figure 2As shown, the front seat of the vehicle includes: a seat cushion 1, a backrest 2, and one or more mounting components 3 arranged on the back side of the backrest 2; wherein one end of the backrest 2 is movably connected to the seat cushion 1; in a normal state, the other end of the backrest 2 is in an upright state to provide support for the occupant; when a child seat is installed, the other end of the backrest 2 is folded forward and stacked with the seat cushion 1 so that the back side of the backrest 2 faces upward, and the child seat is installed on the back side of the backrest 2 using one or more mounting components on the back side of the backrest 2. Specifically, there may be a gap between the stacked backrest 2 and the seat cushion 1, or they may be in a completely fitted state. In the embodiment of the present invention, by folding the backrest 2 forward and stacking it on the seat cushion 1, a space for installing and fixing the child seat is formed on the back side of the backrest 2, breaking through the technical bottleneck of the prior art that only the child seat can be installed in the rear row of the vehicle, and improving the dual riding experience of the child and the driver.

[0029] It can be understood that in order to ensure the stability of the folded backrest when the child seat is installed, in an optional embodiment of the present invention, a fixing device such as a buckle can be provided between the backrest 2 and the seat cushion 1 to lock the backrest 2 after the backrest 2 is folded forward and stacked with the seat cushion 1.

[0030] It should be noted that, in order to improve the riding experience of rear passengers, many vehicles install electronic devices such as electronic screens on the back of the front seat backrest. Therefore, the present invention does not install the child seat directly on the back of the backrest 2 to avoid friction between the child seat and the electronic screen and other electronic devices, causing damage to the electronic devices. In an optional embodiment, Figure 2 As shown, a reversible baffle 4 is also provided on the back side of the backrest 2. When the child seat is installed, the baffle 4 is flipped to an upright state to provide support for the back of the child seat. In the embodiment of the present invention, the baffle 4 is provided to provide a support surface for the child seat to increase the stability of the child seat. Further, in order to improve the interaction between the child and the driver, the child seat is installed facing the direction of the rear seat, that is, the flip direction of the baffle 4 is flipped from the horizontal direction to the front of the vehicle, so that the child can communicate with the driver face to face, further improving the riding experience of the driver and the child. It can be understood that the flip direction of the baffle 4 is different according to the different installation directions of the child seat. In order to increase the diversity of the installation of the child seat, fixing devices can be respectively provided at both ends of the baffle 4, so that the side with the fixing device opened is the reversible side, and the other side is fixedly connected to the backrest 2, that is, the two-way flipping of the baffle 4 is realized. Moreover, when the driver does not want to use the baffle 4 or needs to replace the baffle 4, the baffle 4 can also be removed from the back side of the backrest 2 by opening the fixing devices at both ends.

[0031] In a further optional embodiment, if Figure 2As shown, the mounting component 3 is arranged below the baffle 4; when the child seat is installed, the baffle 4 is flipped open to expose the mounting component 3 on the back of the backrest 2; in the normal state, the baffle 4 is closed to hide the mounting component 3 below the baffle 4. In this way, the mounting component 3 can be hidden inside the backrest 2 in the normal state, which improves the appearance of the backrest 2 and avoids the risk of wear and tear caused by the mounting component 3 being exposed to the outside, which is conducive to improving the durability of the mounting component 3.

[0032] The mounting components may include one or more, and each mounting component may have a different specific structure to improve the firmness between the child seat and the backrest 2. In an optional embodiment, the mounting components include: anti-rollover anchor points and ISOFIX interfaces respectively arranged at the upper and lower ends of the back side of the backrest; wherein the anti-rollover anchor point is arranged at the lower end of the back side of the backrest, so that when the child seat is installed, the child seat is fixed to the back side of the backrest with the back facing away from the driving direction, such as Figure 3 Specifically, the ISOFIX interface is a universal interface for the ISOFIX system (child safety seat fixing system). Many vehicles are equipped with the ISOFIX interface during the vehicle production process. Specifically, it includes two rigid connection points on the vehicle. By connecting the rigid points with the interface on the child seat, the child seat can be quickly and conveniently fixed to the back side of the backrest 2.

[0033] In an optional embodiment, the specific structure of the anti-flip anchor point and the state when in use can be as follows: Figure 4 and Figure 5 As shown, Figure 4 The cross-sectional structure diagram of the anti-rollover anchor point in the unlocked state is shown. Figure 5 The cross-sectional structure diagram of the anti-flip anchor point in the locked state is shown. Figure 4 and Figure 5 As shown, the structure of the anti-flip anchor point specifically includes: a lock base 301, a lock hook 302, a ratchet 303, a ratchet locking rod 304, and a ratchet locking rod return spring 305. The lock hook 302 is U-shaped. When the child seat is not installed, the U-shaped opening of the lock hook 302 faces upward to allow the lock connector of the child seat to be inserted, and the ratchet is in a free rotation state. When the child seat is installed, the lock connector fixedly connected to the child seat is inserted into the U-shaped groove of the lock hook 302, and the lock hook 302 is rotated counterclockwise by a downward external force, so that the ratchet 303 rotates and engages with the ratchet locking rod 304, thereby fixing the child seat. When the child seat needs to be removed, the release handle corresponding to the ratchet locking rod 304 can be manually pulled to contact the locking state between the ratchet locking rod 304 and the ratchet 303, so that the ratchet locking rod 304 is restored to an unused state under the action of the ratchet locking rod return spring 305.

[0034] In the present invention, in order to prevent the vehicle from affecting the child seat during emergency braking or collision, in an optional embodiment, one or more buffer blocks 5 are provided on the side of the baffle 4 facing the back of the backrest 2; the buffer block 5 is made of a flexible material, and when a relative force is generated between the child seat and the baffle 4, the deformation of the buffer block 5 provides a buffer between the back of the child seat and the baffle 4. In the embodiment of the present invention, by providing a buffer block on the side of the baffle 3 facing the back of the backrest 2, after the baffle 3 is flipped open, the buffer block can be used to buffer the relative force between the child seat and the baffle 3, thereby avoiding a direct collision between the child seat and the baffle 3 and improving the riding experience of the child. Specifically, the material of the buffer block can be cobra memory foam, and the slow rebound characteristics of the memory foam can be used to minimize the child's physical sensation of braking or collision.

[0035] In a further optional embodiment, when there are multiple buffer blocks 5, the multiple buffer blocks 5 are arranged at intervals so as to fill the interval area after each buffer block 5 is deformed by force. It is understandable that when the buffer block 5 is deformed, sufficient deformation space needs to be reserved around it to ensure the buffering effect. Therefore, the embodiment of the present invention arranges multiple buffer blocks 5 at intervals to provide sufficient deformation space for each buffer block 5. However, the deformation space should not be too large. In the case where there is no interaction force between the multiple buffer blocks 5, it may cause the problem of insufficient supporting force, that is, the buffer block 5 is completely in a compressed state. Therefore, the embodiment of the present invention sets multiple buffer blocks 5 based on the standard that each buffer block 5 can fill the interval area after being deformed in the hand.

[0036] It can be understood that for different materials of the buffer block, the forces that can be generated when deformation occurs are different, the required deformation space, and the setting of the natural spacing area are also different. In an optional embodiment, for different materials of the buffer block, there are different buffer block ratios and spacing area ratios, as shown in Table 1 below.

[0037] Table 1

[0038] Material Buffer block ratio Interval area ratio cobra memory foam (high resilience polyurethane foam) 90％ 10％ High density sponge 92％ 8％ emulsion 95％ 5％

[0039] Through the above-mentioned different interval area ratios for different materials of the buffer block, the best buffering effect can be achieved through different interval settings when the buffer block is made of different materials, thereby ensuring the safety of the child in the child seat in the event of a collision and improving the safety and feasibility of installing the child seat in the front passenger seat.

[0040] In an optional embodiment, the front seat of the vehicle provided by the present invention further includes: an adjustment button to control the movement of the seat cushion and the backrest so that the child seat is in a rocking state. Specifically, the adjustment button can be set on the side of the seat cushion 1 close to the driver so that the driver can control the state of the child seat, or it can be set on the side of the backrest 2 close to the driver. The present invention does not limit this, as long as it is convenient for the driver to operate.

[0041] Specifically, the rocking state can be understood as controlling the forward and backward movement and the up and down movement of the seat cushion 1 and the backrest so that the child seat is in a reciprocating motion state similar to rocking. Figure 6 As shown, direction A is the forward and backward movement of the seat cushion 1, direction B is the up and down movement of the seat cushion 1, and direction C is the up and down movement of the backrest 2. If the seat cushion 1 moves forward (A+) and the backrest 2 moves upward (C+) at the same time, the child seat can realize an arc movement forward and upward. After reaching the highest point, the seat cushion 1 moves backward (A-) and the backrest 2 moves downward (C-) at the same time, and the child seat can realize an arc movement backward and downward to return to the origin. After reaching the origin, the seat cushion 1 continues to move backward (A-) and moves upward (B+) to realize the arc movement of the child seat backward and upward. After reaching the highest point, the seat cushion 1 moves forward (A+) and moves downward (B-), and the child seat can move forward and downward to return to the origin. Repeat the above reciprocating process, and the movement of the child seat is similar to the rocking movement of a cradle to comfort the child emotionally.

[0042] Above Figures 1 to 6 The front seat of the vehicle provided in the illustrated embodiment folds the seat back so that the backrest can be stacked with the seat cushion after being folded forward, thereby forming a space for installing a child seat on the back side of the backrest, and the child seat is fixed by the mounting parts on the back side of the backrest, so that the driver can place the child in the front passenger seat for easy observation and comfort.

[0043] Figure 7 FIG. 2 is a schematic diagram of the main flow of a method for using a front seat of a vehicle according to an embodiment of the present invention. Figure 7 As shown, the method for using the front seat of a vehicle provided by the embodiment of the present invention includes:

[0044] Step S701: fold the backrest 2 forward and stack it with the seat cushion 1 so that the back side of the backrest 2 faces upward;

[0045] Step S702 : Connect the connection port of the child seat to the mounting component 3 located on the back side of the backrest 2 , so as to mount the child seat on the back side of the backrest 2 .

[0046] In an optional embodiment, in order to ensure the stability of the folded backrest when the child seat is installed, a fixing device such as a buckle can be provided between the backrest 2 and the seat cushion 1 to lock the position of the backrest 2 after the backrest 2 is folded forward and stacked with the seat cushion 1 in step S701.

[0047] In a further optional embodiment, when a baffle 4 is provided on the back side of the backrest 2, after step S701 and before step S702, the method further includes: flipping and opening the baffle 4 on the back side of the backrest 2 to expose the mounting component 3 below the baffle 4. Specifically, one end of the baffle 4 can be selected to be flipped according to the installation direction of the child seat. When the child seat is installed forward, the side of the baffle 4 located at the upper end of the backrest 2 is flipped backward, and when the child seat is installed backward, the side of the baffle 4 located at the lower end of the backrest 2 is flipped forward.

[0048] In an optional embodiment, when the rocking function of the child seat needs to be activated, the rocking function can be activated by turning on the adjustment button set on the front seat of the vehicle, that is, by simultaneously controlling the front and rear and up and down movements of the seat cushion 1 and the backrest 2, the rocking of the child seat can be achieved.

[0049] According to the technical solution of the embodiment of the present invention, the seat back is folded so that the back can be stacked with the seat cushion after being folded forward, thereby forming a space for installing a child seat on the back side of the backrest, and the child seat is fixed by the mounting parts on the back side of the backrest, so that the driver can place the child in the passenger seat for easy observation and comfort.

[0050] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
