Description

Technical Field

[0001] This invention belongs to the technical field of vehicle seats, and particularly relates to automobile seats.

Background Art

[0002] With the rapid development of automobile technology and the increasing needs of consumers for the multifunctionality of vehicles, in order to meet various scenarios, the design of automobile seats is becoming increasingly complex. Modern vehicle seats require not only a comfortable riding experience but also space flexibility. Especially in the case of vehicle types such as SUVs and MPVs, the seat folding function has become an important design element for improving the loading space.

[0003] In the prior art, a foldable seat is generally connected to the vehicle body floor via a hinge connection mechanism, enabling the seat back to be tilted forward or the entire seat back to be folded. To ensure the stability of the seat in the normal riding state, a dedicated position limiting device is installed between the seat frame and the vehicle body structure. As the current mainstream position limiting solution, an elastic U-shaped spring member is used as the position limiting member. Its structural feature is that the opening width of the spring member is smaller than the diameter of the seat support rod member. After the support rod member enters the position limiting space due to elastic deformation, self-locking fixation is realized by the restoring force of the material. According to such a design, it can effectively prevent the seat from moving unintentionally during the running of the vehicle and meet the basic safety requirements.

[0004] However, in actual applications, when the vehicle is subjected to severe vibrations or side collisions, etc., the elastic position limiting member may undergo unexpected deformation due to stress relaxation of the material or the action of instantaneous impact force. In this case, there is a risk that the seat support rod member may accidentally slip out of the opening of the position limiting member, resulting in the loss of the seat positioning function. This situation not only impairs the riding comfort of the passengers but may also pose safety risks, especially in the case of sudden braking or collision accidents, where secondary damage to the passengers may be caused by the unsecured seat.

[0005] Therefore, there is an urgent need to provide automotive seats that can solve some of the problems present in conventional technology. [Overview of the project] [Problems that the invention aims to solve]

[0017] Compared to conventional technology, the automobile seat according to this invention has the following advantages.

[0018] The automobile seat according to the present invention includes a positioning frame, a seat frame, a back frame, an elastic position limiting member, and a floor lock mechanism, wherein the back frame and the positioning frame are rotatably connected, the seat frame and the back frame are rotatably connected, the seat frame includes a seat support rod member, the elastic position limiting member and the floor lock mechanism are fixedly connected to the positioning frame, the seat support rod member and the seat frame are rotatably connected, the floor lock mechanism includes a positioning base, a lock hook, and a trigger assembly, wherein the lock hook and the positioning base are rotatably connected, and the lock hook and the positioning base form a first position limiting space for accommodating and limiting the position of the seat support rod member, the trigger assembly has one end connected to the lock hook and the other end connected to the back frame, and the elastic position limiting member forms a second position limiting space for accommodating and limiting the position of the seat support rod member.

[0033] As shown in Figures 1 to 10, the present invention provides an automobile seat. The automobile seat includes a positioning frame 1, a seat frame 2, a back frame 3, an elastic position limiting member 4, and a floor lock mechanism 5. The back frame 3 and the positioning frame 1 are rotatably connected, and the seat frame 2 and the back frame 3 are rotatably connected. The seat frame 2 includes a seat support rod member 201, and the elastic position limiting member 4 and the floor lock mechanism 5 are fixedly connected to the positioning frame 1, and the seat support rod member 201 and the seat frame 2 are rotatably connected. The floor lock mechanism 5 includes a positioning base, a lock hook 501, and a trigger assembly. The lock hook 501 and the positioning base are rotatably connected, and the lock hook 501 and the positioning base form a first position limiting space for accommodating and limiting the position of the seat support rod member 201. The trigger assembly has one end connected to the lock hook 501 and the other end connected to the back frame 3. A second position limiting space is formed in the elastic position limiting member 4 for accommodating the position limiting sheet support rod member 201.

[0034] Compared to conventional technology, the automobile seat according to this invention has the following advantages.

[0035] The automobile seat according to this invention can have a positioning frame 1 that provides a base for mounting to the seat frame 2, back frame 3, elastic position limiting member 4 and floor lock mechanism 5. The second position limiting space formed in the elastic position limiting member 4 allows for preliminary positioning relative to the seat support rod member 201, and the floor lock mechanism 5, further installed on the positioning frame 1, can further achieve positioning and locking relative to the seat support rod member 201.

[0036] The floor lock mechanism 5 according to this application includes a positioning base, a lock hook 501, and a trigger assembly. The positioning base provides a base for mounting the lock hook 501, and since the lock hook 501 and the positioning base are rotatably connected, the trigger assembly drives the lock hook 501 to rotate it relative to the positioning base, thereby opening and closing the first position limiting space and releasing and locking it relative to the seat support rod member 201.

[0037] In this application, an opening must be formed in the elastic position limiting member 4 in order to allow the seat support rod member 201 to enter the second position limiting space. As a result, the seat support rod member 201 is prone to coming out of the second position limiting space through the opening during use. If the seat support rod member 201 comes out, the seat frame 2 will no longer be locked and will move freely, posing a risk to the occupants. Therefore, this application further adds a floor locking mechanism 5 and enables the locking of the lock hook 501 only through the trigger assembly, thereby ensuring stable positional restriction of the seat support rod member 201 and preventing the problem of the positional restriction of the seat frame 2 becoming invalid during driving.

[0038] Optionally, as shown in Figure 3, the trigger assembly according to this application includes a mounting base 502 and a first traction wire 503, the mounting base 502 being connected to a back frame, and the first traction wire 503 having one end connected to the mounting base 502 and the other end connected to a lock hook 501.

[0039] The mounting base 502 enables a stable connection between the first towing wire 503 and the back frame 3. Of course, as shown in Figure 3, a position limiting base may also be provided inside the seat frame 2 during the wiring process of the first towing wire 503. This allows the wire body portion of the first towing wire 503 to be fitted into the position limiting base, enabling the first towing wire 503 to be wired according to a predetermined position. By connecting the first towing wire 503 to the mounting base 502, when the back frame 3 is tilted toward the seat frame 2, the first towing wire 503 is pulled, the lock hook 501 is rotated, the first position limiting space is opened, and this unlocks the seat support rod member 201.

[0040] Specifically, as shown in Figures 8 to 10, the floor lock mechanism 5 according to this application further includes a positioning plate 504, a first drive block 505, a second drive block 506, and a first tension spring 507. The positioning plate 504 is installed on a positioning base, the first drive block 505 is rotatably connected to the positioning plate 504, and the second drive block 506 is rotatably connected to the positioning plate 504 and fixedly connected to the first drive block 505. A first connecting column 5051 is formed on the first drive block 505, and a second connecting column 5061 is formed on the second drive block 506. The end of the first traction wire 503 spaced away from the mounting base 502 is connected to the first connecting column 5051, and one end of the first tension spring 507 is connected to the second connecting column 5061. The lock hook 501 is rotatably connected to the positioning plate 504, and a third connecting column is formed on the lock hook 501, with the other end of the first tension spring 507 connected to the third connecting column.

[0041] The positioning plate 504 provides a base for mounting, and the positioning plate 504 and the positioning base are connected, thereby rotatably connecting the first drive block 505 and the positioning plate 504, and the formation of a first connecting column on the first drive block 505 contributes to the connection between the first traction wire 503 and the first drive block 505.

[0042] The second drive block 506 is rotatably connected to the positioning plate 504 and fixedly connected to the first drive block 505. That is, the relative positions of the first drive block 505 and the second drive block 506 are fixed, and when the first drive block 505 rotates, the second drive block 506 can be driven to rotate.

[0043] Since the second connecting column 5061 is formed on the second drive block 506, one end of the first tension spring 507 can be connected to the second drive block 506, and the other end of the first tension spring 507 is connected to the lock hook 501. As a result, when the first drive block 505 is pulled by the first traction wire 503 to rotate relative to the positioning plate 504, the second drive block 506 is driven to rotate, thereby displacing the second connecting column 5061. Furthermore, the first tension spring 507 pulls the lock hook 501 to rotate, thereby opening the first position limiting space and releasing the seat support rod member 201.

[0044] Accordingly, as shown in Figures 8 to 10, the floor lock mechanism 5 according to this application further includes a torsion spring 508. A first positioning portion 5052 is formed on the first drive block 505, a second positioning portion 5041 is formed on the positioning plate 504, and the torsion spring 508 is installed such that one end is fitted into the first positioning portion 5052 and the other end is fitted into the second positioning portion 5041.

[0045] The torsion spring 508, which is additionally installed between the positioning plate 504 and the first drive block 505, enables the first drive block 505 to return to its original position. Specifically, when the first drive block 505 is pulled to rotate by the first traction wire 503, a torsional force is generated in the torsion spring 508. After the first traction wire 503 loses its traction force, for example, when the back frame 3 and seat frame 2 return to the state shown in Figure 1, the first traction wire 503 no longer applies tensile force to the first drive block 505. As a result, the torsion spring 508 releases its torsional force and drives the first drive block 505 to rotate to its initial position, and drives the second drive block 506 to rotate to its initial position, thereby enabling the automatic return of both the first drive block 505 and the second drive block 506.

[0046] Since the lock hook 501 does not have a torsion spring 508 structure installed, the lock hook 501 does not automatically return after being released, and the first drive block 505 can still contact the lock hook 501 even after returning under the action of the torsion spring 508, thereby preventing the lock hook 501 from swinging freely. When it is necessary to lock the seat support rod member 201 again with the lock hook 501, the seat support rod member 201 is simply pushed downwards, and the contact force rotates the lock hook 501. In the unlocked state, the first drive block 505 and the lock hook 501 come into contact, so when the lock hook 501 is rotated by pushing downwards, the first drive block 505 also rotates to some extent, thereby returning the lock hook 501 to its initial locked state and achieving locking on the seat support rod member 201.

[0047] Optionally, as shown in Figure 9, a positioning notch 5042 is formed in the positioning plate 504 according to this application, and the first traction wire 503 is installed such that the wire body portion fits into the positioning notch 5042.

[0048] The diameter of the entrance to the positioning notch 5042 is smaller than the diameter of the wire body. This ensures that after the first traction wire 503 enters the positioning notch 5042, the entrance is used to restrict its position, thereby guaranteeing that the first traction wire 503 operates stably.

[0049] As shown in Figures 2 and 4, the automobile seat according to this application further includes a second traction wire 6, a rotating shaft 8, a first interlocking member 7, and an adjustment member 9. The second traction wire 6 is arranged along the side of the back frame 3, with one end protruding from the top of the back frame 3 and the other end connected to one end of the first interlocking member 7, the other end of the first interlocking member 7 connected to the rotating shaft 8, and adjustment members 9 are installed at each end of the rotating shaft 8, with the adjustment members 9 connected to the back frame 3.

[0050] To enable rotation of the back frame 3, this application provides a second traction wire 6 positioned on the side of the back frame 3, with one end of the second traction wire 6 protruding from the top of the back frame 3, thereby contributing to traction by the operator. The other end of the second traction wire 6 is connected to the first interlocking member 7, so that when the second traction wire 6 is pulled, one end of the first interlocking member 7 can be pulled upward. Since the first interlocking member 7 and the rotating shaft 8 are fixedly connected, the rotating shaft 8 can be driven to rotate.

[0051] The adjustment member 9 in this application is an angle adjustment device, and a star rod is installed inside it. The rotating shaft 8 is connected to the star rod, and when the rotating shaft 8 rotates, it drives the star rod to rotate within the angle adjustment device, thereby unlocking the angle adjustment device and thus unlocking the back frame 3. The cooperative structure between the angle adjustment device and the star rod is a common structure for adjusting the seat angle in this field, so a detailed explanation is omitted here.

[0052] When unlocking the automobile seat according to this application, first, the back frame 3 is unlocked using the second towing wire 6, and then the first towing wire 503 is pulled by rotating the back frame 3 toward the seat frame 2, thereby unlocking the lock hook 501. When it is necessary to raise the back frame 3 and seat frame 2, force is applied to raise the back frame 3.

[0053] When the back frame 3 is in the upright position, in order to return the back frame 3 and the seat frame 2 to their original positions, first, the back frame 3 and the seat frame 2 are tilted to engage the seat support rod member 201 with the first and second position limiting spaces, and then the lock between the star rod and the angle adjustment device is released by further pulling the second traction wire 6, thereby enabling the back frame 3 to tilt.

[0054] Optionally, as shown in Figures 5 to 7, the automobile seat according to the present invention further includes a locking mechanism. The locking mechanism includes a positioning lock block 10 and a locking assembly. The positioning lock block 10 is installed on the side of the back frame 3 and has a lock groove 1001 formed in it. The locking assembly is installed on the side of the seat frame 2 and has one end connected to a seat support rod member 201 and the other end engaged with the lock groove 1001, and the seat support rod member 201 can pull the end of the locking assembly that engages with the lock groove 1001 to move away from the lock groove 1001.

[0055] As shown in Figure 5, when the back frame 3 is folded relative to the seat frame 2, a positioning lock block 10 is further installed on the side of the back frame 3 according to this application to prevent the back frame 3 from moving up and down due to inertia, and a corresponding unlock assembly is installed on the side of the seat frame 2. In this embodiment, the seat support rod member 201 and the seat frame 2 are rotatably connected, so that after the lock of the seat support rod member 201 is released, the unlock assembly can be moved by rotating the seat support rod member 201 to engage or disengage the unlock assembly and the lock groove 1001, and thus the lock between the seat frame 2 and the back frame 3 can be released.

[0056] The installed positioning lock block 10 and unlock assembly prevent the seat frame 2 and back frame 3 from separating in the upright position.

[0057] Preferably, as shown in Figures 5 to 7, the unlock assembly according to this application includes a third traction wire 11, a second interlocking member 12, and a third interlocking member 13. One end of the third traction wire 11 is connected to a seat support rod member 201, and the other end is connected to the first end of the second interlocking member 12. The second interlocking member 12 is rotatably connected to the seat frame 2, and the second end of the second interlocking member 12 is rotatably connected to the first end of the third interlocking member 13. The third interlocking member 13 is rotatably connected to the seat frame 2, and a lock tongue 1301 is formed on the second end of the third interlocking member 13, with the lock tongue 1301 aligning with the lock groove 1001.

[0058] Since one end of the third traction wire 11 according to this application is connected to the seat support rod member 201, when the seat support rod member 201 rotates outward from a state in close contact with the seat frame 2, it pulls the third traction wire 11 and drives the second interlocking member 12 to rotate, which in turn drives the third interlocking member 13 to rotate, causing the lock tongue 1301 of the third interlocking member 13 to disengage from the lock groove 1001, thereby unlocking the seat frame 2 and the back frame 3.

[0059] Optionally, as shown in Figure 6, a slot hole 1302 is formed at the first end of the third interlocking member 13 according to this application, and a slide column 1201 is formed at the second end of the second interlocking member 12 corresponding to the slot hole 1302, and the slide column 1201 is installed in the slot hole 1302. A second tension spring 14 is installed on the side of the seat frame 2 at a position corresponding to the second interlocking member 12. One end of the second tension spring 14 is connected to the seat frame 2, and the other end is connected to the second interlocking member 12.

[0060] When the seat support rod member 201 rotates and comes into close contact with the seat frame 2, the third traction wire 11 is no longer subjected to tensile force and has no effect on the second interlocking member 12. In this case, the second tension spring 14 can pull the second interlocking member 12 to rotate to its initial state, thereby driving the lock tongue 1301 of the third interlocking member 13 to engage with the lock groove 1001 and locking the seat frame 2 and the back frame 3.

[0061] Of course, as shown in Figure 1, the automobile seat according to the present invention further includes a slide rail 101, and the positioning frame 1 is installed on the slide rail 101 and is slidable along the extending direction of the slide rail 101.

[0062] The above describes only preferred embodiments of the present invention and does not limit it. All modifications, equivalent substitutions, improvements, etc., that do not depart from the essence and spirit of the present invention are all within the scope of protection of the present invention.
