Description

Technical Field

[0001] This invention relates to child safety seats, and more particularly to a child safety seat with a reversible ISOFIX connector. Background Technology

[0002] Currently, most child safety seats on the market have a single-ended connector core on each side of the independent base for locking and connecting to the ISOFIX interface of the vehicle seat. The independent base also features a mechanism that allows the seat body to be locked in both directions or rotated, enabling forward and backward adjustment. This design results in relatively large and heavy child safety seats. Furthermore, because the base and seat body are two separate components, they are difficult to handle and carry during travel, leading to a strenuous and unpleasant user experience. Therefore, this design does not meet the needs of users who require lightweight and portable vehicles.

[0003] To address the issue of bidirectional installation of the seat body without requiring a separate base, the current industry solution involves designing the connector core as a double-ended structure with two extended cores, directly deployed on both sides of the bottom of the seat body. This allows the base to be plugged into and locked into the vehicle's ISOFIX interface from both the front and rear directions. However, this design still has flaws. To meet safety regulations, the connector cores are typically made of steel, and doubling the length of the two cores directly doubles the weight. While eliminating the base, it doesn't reduce the overall weight.

[0004] Another existing technology employs a method where a pivot point is placed in the middle of the base, allowing the connector sleeve to rotate 180 degrees to switch between forward and backward directions for insertion into the ISOFIX connector on the car seat. However, this simple rotation causes the standard notch on the connector sleeve to turn in the opposite direction. In other words, a simple 180-degree rotation of the connector sleeve results in a non-compliant insertion notch head, which is not permitted by safety regulations and prevents it from being used for locking and connecting to the ISOFIX interface of a motor vehicle.

[0005] In view of the above-mentioned technical problems, this invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a child safety seat with a reversible ISOFIX connector. The left and right sides of the seat body each use a single ISOFIX connector, which can be flipped forward or backward relative to the seat body. During the flipping process, the direction of the eccentric notch is adjusted by a self-rotating linkage component. It has the feature of convenient reversible switching. After the ISOFIX connector is switched, the eccentric notch can be adjusted to meet the safety requirements and be connected to the ISOFIX socket on the car seat. At the same time, since the left and right sides of the seat body use a single ISOFIX connector, the child safety seat has a light weight without being disassembled, which makes it easy to carry and transport.

[0007] To address the aforementioned technical problems, the present invention includes a child safety seat with a reversible ISOFIX connector, comprising a seat body and an ISOFIX connector assembly. One end of the ISOFIX connector assembly is a free end with an eccentric notch for connection to an ISOFIX socket on a car seat. The other end of the ISOFIX connector assembly is a rotatable connection end rotatably connected to the center of the bottom side of the seat body, allowing it to flip forward or backward. A space is provided between the rotatable connection end of the ISOFIX connector assembly and the seat body to accommodate the forward or backward flipping of the ISOFIX connector assembly. During rotation, a rotation linkage component is included to adjust the eccentric notch by rotating the ISOFIX connection assembly along its length axis. The rotation linkage component includes a gear that is movably connected to the ISOFIX connection assembly and a toothed block fixedly disposed at the bottom of the seat body. The gear can mesh with the toothed block to enable the ISOFIX connection assembly to rotate along its length axis during the forward and backward flipping process. The bottom of the seat body is provided with a connecting shaft, and the rotation linkage component also includes a flip joint connected to the connecting shaft. The flip joint is rotatably connected to the rotating connection end of the ISOFIX connection assembly.

[0008] As described above, a child safety seat with a reversible ISOFIX connector is provided between the ISOFIX connector and the bottom of the seat body, and a locking component is provided to lock the ISOFIX connector when the ISOFIX connector is flipped and rotated to a preset position.

[0009] As described above, a child safety seat with a reversible ISOFIX connector, wherein the gear is a bevel gear and the number of teeth on the gear block is equal to that on the bevel gear.

[0010] As described above, a child safety seat with a reversible ISOFIX connector has a screw connection section at the rotating connection end of the ISOFIX connection assembly, and a threaded connection hole on the flip joint that mates with the screw connection section so that the ISOFIX connection assembly can rotate relative to the flip joint during the forward and backward flipping process.

[0011] As described above, a child safety seat has a reversible ISOFIX connector, wherein the flip-top joint is rotatably connected to the connecting shaft so that the ISOFIX connecting components located on both sides of the bottom of the seat body can flip forward or backward in a synchronized manner.

[0012] As described above, a child safety seat with a reversible ISOFIX connector includes a housing and a connector core that is telescopically and adjustably placed within the housing. The eccentric notch is located at the free end of the connector core. The ISOFIX connector also includes locking adjustment buttons located on both sides of the housing for adjusting the telescopic movement of the connector core relative to the housing.

[0013] As described above, a child safety seat with a reversible ISOFIX connector has a groove at the bottom of the seat body for accommodating the ISOFIX connection assembly, and a clearance space at the bottom of the seat body and on the side of the groove for accommodating the movement of the locking adjustment button.

[0014] As described above, a child safety seat with a reversible ISOFIX connector is provided at the bottom of the seat body and on the side of the locking component. This is a locking linkage component that can be used to brake the locking component when the locking component is unlocked, and can trigger the locking component to lock the ISOFIX connection component when the ISOFIX connection component is flipped and rotated to a preset position.

[0015] As described above, a child safety seat with a reversible ISOFIX connector includes a locking assembly comprising a lock hole on the free end of the ISOFIX connector, a locking member correspondingly disposed on the front and rear sides of the bottom of the seat body for inserting or retracting from the lock hole, and an unlocking button disposed on the seat body for driving the locking member.

[0016] As described above, a child safety seat with a reversible ISOFIX connector includes a locking assembly further comprising a locking elastic member for elastically pressing against the locking member. The locking linkage assembly includes a spring piece connected to the locking member and a trigger member whose end can elastically extend from the bottom of the seat body for triggering the locking member when the ISOFIX connection assembly is flipped and rotated to a preset position. The spring piece has a bent latching portion. The trigger member is provided with a hook for engaging with the latching portion when the unlock button is applied to drive the locking member to slide and disengage from the lock hole. The outer end of the trigger member is provided with a trigger guide structure so that when the ISOFIX connection assembly presses against the outer end of the trigger member, the hook presses against the spring piece to deform it and cause the hook to disengage from the latching portion, and the locking member is then elastically inserted into the lock hole.

[0017] As described above, a child safety seat with a reversible ISOFIX connector has a color marking A at the outer end of the locking member, and the seat body also has a window A on which the color marking A can be observed when the locking member is inserted into the lock hole.

[0018] In another embodiment of the locking assembly in this invention, the locking assembly includes a locking rotating member, a hook, and a locking clamp. The middle part of the locking rotating member is rotatably connected to the front and rear sides of the bottom of the seat body via a pivot. The hook is elastically and slidably connected to the bottom of the seat body. One end of the locking rotating member is provided with a slot for engaging with the hook. The other end of the locking rotating member is eccentrically pivotally hinged to the locking clamp. When the slot is engaged with the hook, flipping the locking clamp allows the locking clamp to be fastened onto the free end of the ISOFIX connection assembly, thereby locking the ISOFIX connection assembly.

[0019] As described above, the locking assembly of a child safety seat with a reversible ISOFIX connector further includes an elastic damping element placed on the seat body for elastically pressing against the hook to elastically prevent the hook from being pulled by the locking rotating element.

[0020] As described above, in a child safety seat with a reversible ISOFIX connector, the lever arm of the latch under the action of the hook is greater than the lever arm of the locking clamp acting on the rotating component.

[0021] As described above, a child safety seat with a reversible ISOFIX connector has a color-coded part B on the sliding end of the hook, and a window B on the seat body that allows the color-coded part B to be observed when the locking clamp is fastened to the free end of the ISOFIX connector and the ISOFIX connector is locked.

[0022] As another way in which the ISOFIX connection assembly described in this invention can be rotatably connected to the flip joint, the rotatable connection end of the ISOFIX connection assembly is rotatably connected to the flip joint via a ball joint so that the ISOFIX connection assembly can rotate relative to the flip joint during the forward and backward flipping process.

[0023] As another technical solution of the locking component in this invention, the locking component includes a lock hole disposed on the ISOFIX connecting component, locking members disposed on the front and rear sides of the bottom of the seat body for cooperating with the lock hole, and an unlocking button disposed on the seat body for driving the locking members to move along their axial direction; and the locking component located on the front side of the bottom of the seat body also includes a connecting bushing for rotatably connecting with the corresponding locking member and a support rod connected to the corresponding locking member and rotatably flipped around the locking member relative to the seat body. The connecting bushing is also axially connected to the corresponding locking member. The other end of the two support rods is provided with a support locking pin for inserting into the lock hole when the ISOFIX connecting component is flipped to the front side of the bottom of the seat body to a preset angle. The unlocking button located on the front side of the bottom of the seat body is connected to the connecting bushing to drive the connecting bushing to push the corresponding locking member to move along its axial direction to unlock.

[0024] As described above, a child safety seat with a reversible ISOFIX connector is provided at the bottom of the seat body and on the side of the locking component. This is a locking linkage component that can be used to brake the locking component when the locking component is unlocked, and can trigger the locking component to lock the ISOFIX connector when the ISOFIX connector is flipped and rotated to a preset position in the groove.

[0025] As described above, a child safety seat with a reversible ISOFIX connector includes a locking linkage assembly located at the rear bottom of the seat body. This assembly includes a spring piece movably connected to a corresponding locking element and a trigger element whose end extends elastically out of the bottom of the seat body to trigger the locking element when the ISOFIX connector is flipped and rotated to a preset position within the groove. The spring piece has a bent locking portion, and the trigger element has a hook that engages with the locking portion when the unlock button is pressed to drive the locking element to slide and disengage from the lock hole. The outer end of the trigger element has a trigger guide structure. Similarly, a locking linkage assembly located at the front bottom of the seat body includes a spring piece movably connected to a connecting sleeve and a trigger element whose end extends elastically out of the bottom of the seat body to trigger the locking element when the ISOFIX connector is flipped and rotated to a preset position within the groove. The spring piece has a bent locking portion, and the trigger element has a hook that engages with the locking portion when the unlock button is pressed to push the connecting sleeve inward and disengage from the lock hole. The outer end of the trigger element has a trigger guide structure.

[0026] As described above, a child safety seat with a reversible ISOFIX connector has at least one trigger lock button on the front and rear sides of the bottom of the seat body. Each trigger lock button is connected to a trigger element to indirectly or directly trigger the lock element to perform a locking action by driving the trigger element.

[0027] As described above, a child safety seat with a reversible ISOFIX connector has a crossbar connected to the other end of each of the two support rods. A guide sleeve is slidably connected between the inner ends of the two crossbars. The guide sleeve is provided with push springs at both ends that abut against the inner ends of the two crossbars respectively.

[0028] As described above, a child safety seat with a reversible ISOFIX connector has a slot at the bottom of the seat body for storing a support rod.

[0029] As described above, a child safety seat with a reversible ISOFIX connector has a guide positioning groove on the ISOFIX connector assembly and located at the edge of the lock hole, which is used to support the positioning of the locking pin and guide its insertion into the lock hole when the ISOFIX connector assembly is flipped to a preset angle towards the front bottom of the seat body.

[0030] Compared with the prior art, the child safety seat of the present invention, which has a reversible ISOFIX connector, has the following advantages:

[0031] 1. The ISOFIX connection assembly can be flipped forward and backward to connect to the middle of the bottom side of the seat body, and is equipped with a self-rotation linkage component, so that the ISOFIX connection assembly can rotate during forward or backward flipping. The purpose of self-rotation is to adjust the eccentric notch of the ISOFIX connection assembly to the direction that meets the safety requirements, so as to connect with the ISOFIX socket on the car seat in a compliant and safe manner, ensuring the safe and reliable connection between the child safety seat and the motor vehicle.

[0032] 2. Because the ISOFIX connection components are designed to be synchronously flipped and rotated, they meet the requirements for front-to-back reversible connection and installation of the seat body, while also satisfying the user's need for synchronous front-to-back reversible switching.

[0033] 3. The ISOFIX connection component of the present invention adopts the above technical solution. Compared with the prior art, it effectively avoids the double-head connection structure with two connector cores on one side of the bottom of the seat body, and does not require a base, effectively reducing the overall weight of the child safety seat, realizing a lightweight structural design, and making it convenient for users to carry and use when traveling.

[0034] 4. In this invention, after the ISOFIX connection component is unlocked, the upright seat body can automatically flip using the gravity drive of the ISOFIX connection component itself. During the forward or backward flipping process, the self-rotation linkage component automatically rotates to adjust the eccentric notch to the connection position that meets the safety requirements. It has the characteristics of convenient operation and prevention of misuse, and improves the user's operating experience.

[0035] 5. In this invention, when the ISOFIX connection component is unlocked and flipped to the other side to a preset position, the ISOFIX connection component abuts against the locking linkage component, thereby the locking component can automatically lock the ISOFIX connection component at the bottom of the seat body, further optimizing the ease of use of the product of this invention.

[0036] 6. To further enhance the usability and improve the overall effect, windows A and B are provided on the seat body. When the ISOFIX connection components are locked, the user can observe the color markings A and B through windows A or B respectively to ensure that the ISOFIX connection components are reliably locked.

[0037] 7. In this invention, the ISOFIX connecting components on the left and right sides can be flipped synchronously via the connecting shaft, further improving the convenience of using them to flip forward or backward.

[0038] 8. A support rod is installed on the locking member located at the bottom front of the seat body. When the support locking pin of the support rod is inserted into the locking hole on the ISOFIX connection assembly at the preset angle at the bottom front of the seat body, the seat body can generate an tilt angle. Users can adjust the tilt angle as needed, and meet the needs of fully seated child safety seats being installed rearward at the set tilt angle and quickly and accurately locking the support angle.

[0039] 9. To facilitate users in accurately positioning the seat body's tilt angle and accurately aligning it with the locking hole on the ISOFIX connector, a guide positioning groove is provided on the ISOFIX connector and on the side of the locking hole. When the support rod on the locking component is in the open state, the ISOFIX connector flips over until it is stopped by the guide positioning groove against the support locking pin. Then, by pressing the locking button with one hand, the support locking pin can be accurately inserted into the locking hole.

[0040] 10. To facilitate the insertion of the support lock pin into the lock hole for locking, a trigger lock button is provided on the front bottom of the seat body. The user can trigger the lock button with one hand to insert the support lock pin into the lock hole.

[0041] 11. To facilitate the insertion of the support lock pin into the lock hole for locking, a push spring is provided between the inner ends of the two crossbars and a locking elastic element is provided between the inner ends of the two locking parts to help the support lock pin insert into the lock hole. At the same time, an unlock button is provided on the front side of the bottom of the seat body, and the user can use the unlock button to smoothly release the lock pin. Attached Figure Description

[0077] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0078] like Figure 1-28 As shown, the present invention includes a child safety seat with a reversible ISOFIX connector, comprising a seat body 1 and an ISOFIX connector 2. One end of the ISOFIX connector 2 is a free end and has an eccentric notch 21 for connecting to an ISOFIX socket on a car seat. The other end of the ISOFIX connector 2 is a rotatable connection end and is rotatably connected to the middle of the bottom side of the seat body 1, allowing it to flip forward or backward. Between the rotatable connection end of the ISOFIX connector 2 and the seat body 1, there is a rotation linkage component 3 that, during the forward or backward flipping of the ISOFIX connector 2, links the ISOFIX connector 2 to rotate along its length axis to adjust the eccentric notch 21. Between the portion of the ISOFIX connector 2 away from the rotatable connection end and the bottom of the seat body 1, there is a locking component 4 for locking the ISOFIX connector 2 when it is flipped and rotated to a preset position. The present invention adopts the above-mentioned technical solution. The ISOFIX connection component is easy to switch and use. After switching the direction, the eccentric notch of the ISOFIX connection component can be adjusted to meet the safety requirements and connect with the ISOFIX socket on the car seat. At the same time, the child safety seat has a lighter weight without being disassembled, which makes it easy to carry and move.

[0079] like Figure 3 , 4 and Figure 10 , 11 As shown, the self-rotating linkage component 3 includes a gear 31 that is movably connected to the ISOFIX connection component 2 and a toothed block 32 fixedly disposed at the bottom of the seat body 1. The gear 31 is a bevel gear, and the teeth on the toothed block 32 are arranged in a fan shape. Thus, the gear 31 can mesh with the toothed block 32, and the number of teeth on the gear 31 and the toothed block 32 is equal. When the ISOFIX connection component moves forward or backward, it rotates exactly 180°, thus meeting the connection requirements of the eccentric notch 21 with the ISOFIX connector on the car seat. Alternatively, the number of teeth on the toothed block 32 is an odd multiple of the number of teeth on the gear 31. In this case, when the ISOFIX connection component moves forward or backward, it rotates exactly an odd multiple of 180°, also meeting the connection requirements of the eccentric notch 21 with the ISOFIX connector on the car seat. Therefore, it meets the requirements for reversible connection of the seat body and also satisfies the user's reversible switching needs, ensuring a safe and reliable connection.

[0080] like Figure 23 As shown, in order to ensure stable and reliable meshing transmission between gear 31 and tooth block 32, a stop block 15 is provided on the bottom of the seat body 1 facing the tooth block 32. When gear 31 meshes with tooth block 32, a stop block 15 is provided to tangentially abut against gear 31. A gap is formed between the stop block 15 and tooth block 32 for gear 31 to pass through.

[0081] like Figure 11 , 21 As shown, the bottom of the seat body 1 is provided with a connecting shaft 5, and the self-rotation linkage component 3 also includes a flip joint 33 connected to the connecting shaft 5. The flip joint 33 is rotatably connected to the rotating connection end of the ISOFIX connection component 2. The rotating connection end of the ISOFIX connection component 2 is provided with a screw connection section 34. The screw connection section 34 is relatively fixedly connected to the housing 22 of the ISOFIX connection component 2. The flip joint 33 is provided with a threaded connection hole 35 that cooperates with the screw connection section 34 so that the ISOFIX connection component 2 can rotate relative to the flip joint 33 during the forward and backward flipping process.

[0082] In order to achieve synchronous and coordinated flipping of the ISOFIX connecting components on both sides of the seat body 1, the connecting shaft 5 is connected to the flipping joint 33 in a coordinated manner. When the ISOFIX connecting component 2 flips forward or backward, the threaded connecting hole 35 of the flipping joint 33 and the screw connecting section 34 of the ISOFIX connecting component 2 are threaded together. When the ISOFIX connecting component 2 rotates, it will be screwed out or screwed in accordingly. However, the screw connecting section 34 always maintains a threaded connection with the threaded connecting hole 35 with a considerable number of turns to ensure the connection strength.

[0083] In this invention, the ISOFIX and the flip connector 33 are rotatably connected (not shown in the figure). The rotatable connection end of the ISOFIX connection assembly 2 can be rotatably connected to the flip connector 33 via a pivot.

[0084] like Figure 19 As shown, the ISOFIX connection assembly 2 includes a housing 22 and a connector core 23 that is telescopically and adjustablely placed within the housing 22. The eccentric notch 21 is located at the outer end of the connector core 23. The ISOFIX connection assembly 2 also includes locking adjustment buttons 24 disposed on both sides of the housing 22 for adjusting the telescopic movement of the connector core 23 relative to the housing 22. Regarding the structure of the connector core 23, Chinese patent ZL201820031750.9 discloses a specific structure. The difference between the ISOFIX connection assembly 2 in this invention and the patent is that locking adjustment buttons 24 are designed on both sides of the connector core 23. In this invention, the two locking adjustment buttons 24 on the same connector core 23 are connected synchronously, and regardless of which one is activated, the connector core 23 can be slidably adjusted and locked relative to the housing 22.

[0085] like Figure 1 , 2 , Figure 4-8 and Figure 23-25 As shown, the bottom of the seat body 1 has a groove 11 for accommodating the ISOFIX connecting assembly 2, and the bottom of the seat body 1, located on the side of the groove 11, has a clearance space 12 for avoiding the movement of the locking adjustment button 24. When the ISOFIX connecting assembly 2 completes its rotation, it is fully embedded in the groove 11, making its structure compact. The clearance space 12 includes a clearance notch near the connecting shaft 5 and a sliding groove that communicates with the clearance notch and extends in the front-rear direction of the seat body. When the ISOFIX connecting assembly 2 is rotated, the locking adjustment button 24 should be adjusted to the clearance notch position beforehand; otherwise, interference will occur, and the rotation cannot be unlocked.

[0086] like Figure 13-18As shown, the bottom of the seat body 1, located on the side of the locking component 4, is also provided with a locking linkage component 6, which is used to brake the locking component 4 when the locking component 4 is unlocked, and can trigger the locking component 4 to lock the ISOFIX connection component 2 when the ISOFIX connection component 2 is flipped and rotated to a preset position. Therefore, when the ISOFIX connection component 2 is flipped and rotated to the preset position, that is, when the ISOFIX connection component 2 is embedded in the groove 11, the ISOFIX connection component 2 can be automatically locked without the user's additional operation, making the use more convenient.

[0087] The locking assembly 4 includes a lock hole 41 located on the free end of the ISOFIX connector 2, locking members 42 correspondingly located on the front and rear sides of the bottom of the seat body 1 that can be inserted into or removed from the lock hole 41, and an unlocking button 43 located on the seat body 1 for driving the locking member 42. The lock hole 41 is located on the housing 22, specifically, as shown in... Figure 19 As shown, a U-shaped connecting lug 221 is provided on the housing 22, and a locking hole 41 is provided on both sides of the connecting lug 221. The locking assembly 4 also includes a locking elastic member 44 for elastically pressing the locking member 42, and the two ends of the locking elastic member 44 elastically abut against the two locking members 42 respectively.

[0088] In one embodiment of the present invention, the unlock button 43 is movably connected to the locking member 42 to drive the locking member to slide along its axial direction. When the user applies the unlock button 43 to overcome the elastic force of the locking elastic member 44, the unlock button 43 drives the locking member 42 to slide along its axial direction and disengage from the lock hole 41, thereby realizing the unlocking operation of the ISOFIX connection assembly 2.

[0089] like Figure 13 and Figure 15-20 As shown, the locking linkage assembly 6 includes a spring piece 61 that moves in tandem with the locking member 42 and a trigger member 62 whose one end can elastically extend out of the bottom of the seat body 1 so that the locking member can be triggered when the ISOFIX connection assembly 2 is flipped and rotated to a preset position. The spring piece 61 has a bent locking portion 611, and the trigger member 62 is provided with a hook 621. When the unlock button 43 is applied to drive the locking member 42 to slide axially and disengage from the lock hole 41, the locking portion 611 that moves in tandem with the locking member 42 moves accordingly. When the locking portion 611 elastically engages with the hook 621, the locking member 42 unlocks and retracts, thus preventing it from sliding outward.

[0090] like Figure 20As shown, the outer end of the trigger 62 is provided with a trigger guide structure 622. To facilitate cooperation with the trigger guide structure 622, regardless of whether the ISOFIX connection assembly is flipped to the front or rear side of the bottom of the seat body 1, corresponding guide slopes 222 are provided on both sides of the connecting ear 221. When the ISOFIX connection assembly 2 flips and rotates to the preset position, the guide slopes 222 abut against the trigger guide structure 622, causing the trigger 62 to elastically retract, thereby driving the hook 621 to slide inward together. The hook 621 then presses against the spring 61 and causes it to elastically deform until the hook 621 disengages from the locking part 611. At this time, as Figure 14 As shown, after the locking member 42 is released from the locking limit, it is elastically inserted into the lock hole 41 under the elastic force of the locking elastic member 44.

[0091] To further enhance usability and improve performance, the outer end of the locking member 42 is provided with a color marking section A421, which can be marked green as needed. The seat body 1 is also provided with a window A13 on which the color marking section A421 can be observed after the locking member 42 is inserted into the lock hole 41, so as to ensure that the ISOFIX connection assembly is reliably locked.

[0092] like Figure 24-28 As shown, in another embodiment of the locking assembly 4 in this invention, the locking assembly 4 includes a locking rotating member 45, a hook 46, and a locking clamp 47. The middle part of the locking rotating member 45 is rotatably connected to the front and rear sides of the bottom of the seat body 1 via a pivot 451. The hook 46 is elastically slidably connected to the bottom of the seat body 1. One end of the locking rotating member 45 is provided with a slot 452 for engaging with the hook 46. The other end of the locking rotating member 45 is eccentrically pivotally connected to the locking clamp 47. The locking assembly 4 also includes an elastic damping member 461 placed on the seat body 1 for elastically pressing the hook 46 to elastically prevent the hook 46 from being pulled by the locking rotating member 45. When the slot 452 is engaged with the hook 46, flipping the locking clamp 47 allows the locking clamp 47 to be fastened onto the free end of the ISOFIX connection assembly 2, thereby locking the ISOFIX connection assembly 2. To ensure a safe and reliable locking mechanism, the lever principle is utilized, and the lever arm of the latch 452 under the action of the hook 46 is greater than the lever arm of the locking clamp 47 under the action of the locking rotating member 45.

[0093] Similarly, in order to further enhance the use and ensure that the ISOFIX connection assembly is locked reliably, the sliding end of the hook 46 is provided with a color marking part B462, and the seat body 1 is provided with a window B14 that allows the color marking part B462 to be observed when the locking clamp 47 is fastened to the free end of the ISOFIX connection assembly 2 and the ISOFIX connection assembly 2 is locked.

[0094] like Figures 29-34 As shown, in another specific embodiment of the present invention, the locking assembly 4 includes a lock hole 41 disposed on the ISOFIX connection assembly 2, locking members 42 disposed on the front and rear sides of the bottom of the seat body 1 for cooperating with the lock hole 41, and an unlocking button 43 disposed on the seat body 1 for driving the locking members 42 to move along its axial direction. Similarly, the inner ends of the two locking members 42 located on the same front or rear side of the bottom of the seat body 1 are elastically pressed together by a locking elastic member 44. The locking assembly 4 located on the front side of the bottom of the seat body 1 also includes a connecting bushing 422 for rotatably connecting with the corresponding locking member 42 and a support rod 423 connected to the corresponding locking member 42 and rotatably flipped around the locking member 42 relative to the seat body 1. The connecting bushing 422 and the corresponding locking member 42 are axially connected and move together. The other end of the two support rods 423 is provided with a support locking pin 424 for inserting into the lock hole 41 when the ISOFIX connection assembly 2 is flipped to the front side of the bottom of the seat body 1 at a preset angle. The unlocking button 43 located at the bottom front of the seat body 1 is connected to the connecting bushing 422 to drive the connecting bushing 422 to push the corresponding locking piece 42 to move along its axial direction to unlock. According to the need for adjusting the angle, multiple sets of locking holes 41 can be provided on the housing 22 of the ISOFIX connecting assembly 2. The user can select according to the needs of use, so that the seat body 1 can obtain different tilt angles and increase practicality.

[0095] When using it, such as Figure 29 As shown, first unlock the ISOFIX connection component 2, flip and rotate it from the bottom rear side of the seat body 1 to the front side to the preset position, that is, the position where the seat body 1 needs to obtain the tilt angle. Then flip the support rod 423, and the locking piece 42 will rotate in the connecting bushing 422 as the support rod 423 flips. When the support rod flips so that the support locking pin 424 is aligned with the locking hole 41 and can be inserted, it is ready.

[0096] To ensure that the two support rods 423 rotate synchronously and that the two support locking pins 424 have sufficient elastic extension and contraction space, each of the two support rods 423 is connected to a crossbar 425 at its other end. A guide sleeve 426 is slidably connected between the inner ends of the two crossbars 425. The guide sleeve 426 contains push springs 427, each with two ends abutting against the inner ends of the two crossbars 425. In this invention, the support locking pin 424 is formed by extending outward from the crossbar 425. Meanwhile, as... Figure 34 As shown, a limiting protrusion 429 is provided on the crossbar 425 to limit the retraction guide sleeve 426 of the inner end of the two crossbars 425, so as to ensure that when the support rod 423 is driven by the locking member 42 to move towards each other for unlocking, the two support locking pins 424 can smoothly disengage from the lock hole 41.

[0097] like Figure 34As shown, the bottom of the seat body 1 is provided with a slot 15 for storing the support rod 423. When the ISOFIX connection assembly 2 is unlocked and flipped to the front of the bottom of the seat body 1 and the tilt angle of the seat body 1 does not need to be adjusted, the support rod 423 and the crossbar 425 are locked in the slot 15; Figure 30 As shown, when the ISOFIX connection component 2 is flipped and rotated to the preset position in the groove 11, the locking piece 42 can be inserted into the lock hole 41.

[0098] like Figure 31 , 32 As shown, the bottom of the seat body 1, located on the side of the locking component 4, is also provided with a locking linkage component 6, which is used to brake the locking component 4 when the locking component 4 is unlocked, and can trigger the locking component 4 to lock the ISOFIX connection component 2 when the ISOFIX connection component 2 is flipped and rotated to a preset position in the groove 11. The locking linkage component 6, located on the rear side of the bottom of the seat body 1, includes a spring piece 61 that is movably connected to the corresponding locking member 42 and a trigger member 62 that can elastically extend from the bottom of the seat body 1 so as to trigger the locking member 42 when the ISOFIX connection component 2 is flipped and rotated to a preset position in the groove 11. The spring piece 61 has a bent latching part 611. The trigger member 62 is provided with a hook 621 that engages with the latching part 611 when the unlock button 43 drives the locking member 42 to slide and disengage from the lock hole 41. The outer end of the trigger member 62 is provided with a trigger guide structure 622. When the ISOFIX connector 2 flips and rotates to the preset position in the groove 11, the guide slope 222 on the connector ear 221 pushes the trigger guide structure 622, causing the hook 621 on the trigger member 62 to squeeze the locking part 611 on the spring 61 to produce elastic deformation until the locking part 611 disengages from the hook 621. In this way, the locking member 42 is inserted into the lock hole 41 under the elastic force of the locking elastic member 44, thus automatically locking the ISOFIX connector 2.

[0099] like Figure 31 , 32 As shown, the locking linkage assembly 6 located at the bottom front side of the seat body 1 includes a spring piece 61 that is movably connected to the connecting bushing 422 and a trigger member 62 whose one end can elastically extend out of the bottom of the seat body 1 so that when the ISOFIX connecting assembly 2 is flipped and rotated to a preset position in the groove 11, the locking member 42 is triggered. The spring piece 61 has a bent locking part 611, and the trigger member 62 is provided with a hook 621 for engaging with the locking part 611. When the unlock button 43 is applied to drive the connecting bushing 422 to push the locking member 42 to overcome the elastic force of the locking elastic member 44 and disengage from the lock hole 41, the locking part 611 is elastically engaged with the hook 621 as the locking member 42 slides, thereby braking and locking the locking member 42. The outer end of the trigger member 62 is provided with a trigger guide structure 622.

[0100] To ensure safe and reliable use, at least the front side of the bottom of the seat body 1 is provided with a trigger locking button 63. Each trigger locking button 63 is connected to a trigger member 62 to indirectly or directly trigger the locking member 42 to perform a locking action by driving the trigger member 62. When the seat body 1 does not need to be adjusted in tilt and the ISOFIX connection assembly 2 is flipped into the groove 11, the locking member 42 can be automatically inserted into the lock hole 41 by pushing the trigger member 62. If the above action does not occur when the ISOFIX connection assembly 2 is flipped into the groove 11, the user can also manually insert the locking member 42 into the lock hole 41 by activating the trigger locking button 63.

[0101] When the seat body 1 needs to be adjusted to the tilt angle and the ISOFIX connecting component 2 is flipped to the appropriate position at the bottom front of the seat body 1, the support rod 423 is released and flipped so that the support locking pin 424 is aligned with the corresponding lock hole 41. Then, the user can trigger the locking button 63 to insert the support locking pin 424 into the lock hole 41 to achieve tilt angle adjustment and locking.

[0102] like Figure 33 As shown, in order for the support rod 423 to be quickly and accurately aligned with the corresponding lock hole 41 during the flipping process, a guide positioning groove 428 is provided on the edge of the lock hole 41 of the connecting ear 222, and when the ISOFIX connecting assembly 2 is flipped to the front side of the bottom of the seat body 1, the guide positioning groove 428 is located inside the housing 22.
