Description

Technical Field

[0001] This disclosure relates to a vehicle seat fixing system and a vehicle, and belongs to the field of vehicle technology. Background Technology

[0002] Currently, the movement mechanisms of most car driver and passenger seats are guided by fixed sliding rails, which strictly limit their range and trajectory. Mainstream models are only equipped with longitudinal sliding rails, allowing the seats to slide linearly along the fore-and-aft direction of the vehicle to accommodate the legroom needs of different drivers. Only a few high-end or special-purpose models add short-stroke lateral sliding rails, but the lateral movement distance is also very small and the cost is high. Most importantly, it still needs to follow a preset track, which is still a single-dimensional or limited two-dimensional movement constraint, and cannot achieve flexible position adjustment of the seat on the horizontal plane inside the vehicle.

[0003] Therefore, how to provide a seat fixing system that can be adapted to the vast majority of car models and can be moved freely at a low cost is an urgent problem to be solved. Summary of the Invention

[0004] This disclosure proposes a vehicle seat fixing system and a vehicle that enables the seat to move freely on the vehicle floor, not limited to traditional single-dimensional or limited two-dimensional movement, and can be applied to a wide variety of vehicle models at a low cost, meeting the needs of drivers and passengers for flexible seat movement.

[0005] More specifically, the first aspect of this disclosure provides a vehicle seat fixing system, comprising: a fixing unit disposed on the vehicle floor and including a plurality of fixing holes arranged in an array and extending in a vertical direction; a connecting unit disposed on the bottom of the vehicle seat and including locking pins retractable in a vertical direction, each of the locking pins being capable of engaging in or disengaging from the fixing holes based on the retraction or extension of the locking pins; and an operating unit communicatively connected to the connecting unit, sending control commands to the locking pins to retract or extend the locking pins, thereby controlling the engagement or disengagement of the locking pins from the fixing holes.

[0006] According to the vehicle seat fixing system with the above configuration, unlike the traditional seat movement trajectory which is rigidly constrained by the slide rail, this disclosure uses an array of fixed holes and a retractable locking pin to enable the vehicle seat to be flexibly adjusted to any position, such as forward, backward, left, right, and diagonal, on the horizontal surface of the vehicle floor, greatly improving the freedom of seat movement. At the same time, the operating unit can conveniently control the extension and retraction of the locking pin. In the unlocked state, the seat can be manually pushed to the target position, and in the locked state, the locking pin and the fixed holes are firmly engaged, ensuring that the seat has reliable support stability in any fixed position. This solves the limitation of existing seats that can only slide along a single trajectory, improving the flexibility of seat movement and the personalized experience of the occupants.

[0007] Preferably, in the fixing system of the first aspect, the connecting unit further includes a support corresponding to the locking pin, the support being fixed to the bottom of the vehicle seat and having a receiving hole extending in the vertical direction, in which the locking pin is retractably received, such that when the locking pin is fully retracted into the receiving hole, the locking pin disengages from the fixing hole, and when the locking pin extends out of the receiving hole, the locking pin engages with the fixing hole.

[0008] According to the fixing system with the above configuration, a support is set to accommodate the locking pin, thereby providing axial rigidity constraint for the locking pin through the receiving hole. This allows for precise guidance of the locking pin to ensure accurate alignment between the locking pin and the fixing hole, improving the reliability of the engagement. Moreover, the support can also strengthen the stable support, enhance the connection strength between the locking mechanism and the seat, ensure that the seat does not wobble or shift during vehicle dynamic driving, and at the same time provide protection for the locking pin to avoid structural damage to the locking pin.

[0009] Preferably, in the fixing system of the first aspect, the end of the support is chamfered.

[0010] According to the fixing system with the above configuration, the end of the support is rounded and chamfered, which can reduce the resistance of seat movement, reduce the contact friction and risk of jamming between the end of the support and the vehicle floor when the seat is manually pushed, make the adjustment of the seat in the horizontal plane smoother, and also reduce wear on the end of the support and scratches on the vehicle floor, and extend the service life of the components.

[0011] Preferably, in the fixing system of the first aspect, the end of the support is provided with a ball roller in the area surrounding the outlet of the receiving hole.

[0012] According to the fixing system with the above configuration, by using ball rollers set at the ends of the supports, the sliding friction between the supports and the floor can be changed into rolling friction when the seat is manually pushed. This makes it easier to push the seat, and the ball rollers distribute the friction load by rotating themselves, which effectively avoids scratches and wear caused by the hard contact between the ends of the supports and the floor, protects the vehicle floor coating, reduces the floor maintenance costs caused by seat movement, and extends the overall service life of the system.

[0013] Preferably, in the fixing system of the first aspect, four supports are provided, each located at one of the four corners of the bottom of the vehicle seat.

[0014] According to the fixing system with the above configuration, the four supports are located at the four corners of the bottom of the seat, which can achieve balanced four-point support. This can not only evenly distribute the load of the seat and the occupants to each support, effectively suppressing the seat shaking during vehicle dynamic driving, but also form a full-range locking constraint through the engagement of the locking pins on the four corners with the fixing holes, preventing the seat from floating and improving the locking reliability.

[0015] Preferably, in the fixing system of the first aspect, the fixing unit further includes a plurality of position detection sensors, each of which is corresponding to one of the plurality of fixing holes, and each position detection sensor is arranged around the edge of the corresponding fixing hole; the connecting unit includes a sensing trigger corresponding to one of the locking pins, the sensing trigger being fixed on the support of the locking pin and adapted to the sensing range of the position detection sensor; the operating unit is configured to: receive the detection signal of the position detection sensor in real time, and when the sensing trigger moves into the sensing range of the position detection sensor, the operating unit outputs an alignment success prompt signal.

[0016] The fixing system with the above configuration can achieve precise alignment detection and intuitive feedback between the locking pin and the fixing hole through the coordinated detection between the position sensor and the inductive trigger and the prompt output of the operating unit. This reduces the difficulty of user operation. Users do not need to visually confirm or repeatedly try. They can quickly judge the alignment status through prompts such as sound and light, improve the locking success rate, avoid the problem of locking pin jamming or failure to engage due to alignment deviation, and further enhance the reliability of the system.

[0017] Preferably, the fixing system of the first aspect further includes: a caster portion, the caster portion being disposed at the bottom of the vehicle seat and including a caster, the lowest point of the caster being substantially flush with or lower than the lowest point of the support.

[0018] According to the fixing system with the above configuration, by adding casters, the weight of the seat and the occupant can also be supported by the casters. Moreover, when the seat is moved, the frictional resistance of the seat movement is further reduced, making it easier and smoother for the seat to move along any trajectory in the horizontal plane, such as forward, backward, left, right, and diagonal, effectively avoiding jamming or tilting when manually pushed.

[0019] Preferably, in the fixing system of the first aspect, the caster portion has a storage structure, enabling the caster to switch between a storage state and a use state. In the storage state, the caster is positioned above the lowest point of the support, while in the use state, at least the lowest point of the caster is positioned lower than the lowest point of the support.

[0020] According to the fixing system with the above configuration, the casters can switch between a storage state and a use state, so that the casters only take effect when unlocked to reduce pushing resistance, while automatically retracting when locked to completely isolate them from the floor, thus extending the service life of the casters.

[0021] Preferably, in the fixing system of the first aspect, the end of the locking pin is tapered or hemispherical, and the inlet of the fixing hole is tapered, such that the diameter of the hole increases towards the upper side.

[0022] According to the fixing system with the above configuration, the end of the locking pin is tapered or hemispherical, and the entrance of the fixing hole is a tapered structure with a larger upper diameter. Thus, the two form a matching guide fit, which facilitates the insertion of the locking pin into the fixing hole, guides the locking pin to accurately engage in the fixing hole, improves the alignment success rate, reduces the alignment requirements of manual operation, and makes the seat fixing operation more convenient.

[0023] Preferably, in the fixing system of the first aspect, the fixing unit further includes a mounting plate portion fixed to the vehicle floor, and the fixing hole is formed in the mounting plate portion.

[0024] According to the fixing system with the above configuration, the mounting plate serves as an integrated carrier for the fixing holes and is fixed to the vehicle floor. Thus, the mounting plate can be fixed to the vehicle floor as a whole after prefabrication without the need for complex processing of the floor. It is compatible with the floor structure of different vehicle models. When the fixing holes are worn or damaged, the mounting plate can be replaced separately without the need to repair the entire vehicle floor, reducing maintenance costs. Furthermore, the array layout of the fixing holes can be flexibly adjusted according to the seat size and locking requirements to adapt to the installation needs of different vehicle models and seat specifications.

[0025] A second aspect of this disclosure provides a vehicle having a vehicle seat securing system according to the first aspect.

[0026] Because the vehicle in the second aspect has the same fixing system as the vehicle in the first aspect, it can also achieve the various technical effects of the first aspect.

[0027] The vehicle seat fixing system and the vehicle disclosed herein have been described in general terms above. The details will be further explained below with reference to the accompanying drawings. Attached Figure Description

[0042] The technical solution of the present invention will be described more clearly below by referring to the accompanying drawings and specific embodiments.

[0043] It should be noted that the accompanying drawings of this invention are merely schematic diagrams for clearly illustrating the parts related to the present invention, and do not show some unnecessary parts. Therefore, these drawings should not be construed as limiting the invention, and may differ from the actual structure in use.

The description is based on the conventional state of the vehicle with the seats facing forward. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0044] This disclosure provides a vehicle seat fixing system and a vehicle that enables the seat to move freely on the floor, not limited to traditional single-dimensional or limited two-dimensional movement, and can be applied to a wide variety of vehicle models at a low cost, meeting the needs of drivers and passengers for flexible seat movement.

[0045] <First Embodiment>

[0046] Figures 1-5 A first embodiment of the fixing system 1 for a vehicle seat 200 disclosed herein is described, wherein, Figure 1 This is a schematic diagram showing the fixing unit 10 in the fixing system 1; Figure 2 This is a schematic diagram showing the connection unit 20 in the fixed system 1; Figure 3 This is a schematic diagram showing the mutual states between the fixing unit 10 and the connecting unit 20 in the fixing system 1 of this disclosure, wherein (A) shows the mutually unlocked state and (B) shows the mutually locked state; Figure 4 It corresponds to Figure 3 The diagram in (A) is shown; and Figure 5 It corresponds to Figure 3The diagram is shown in (B).

[0047] like Figures 1-5 As shown, the fixing system 1 for a vehicle seat 200 according to the first embodiment of this disclosure includes: a fixing unit 10, which is disposed on the vehicle floor 100 and includes a plurality of fixing holes 11 arranged in an array and extending in the vertical direction (see...). Figure 1 (The number and arrangement of fixing holes 11 are merely examples and not limiting; various numbers and arrangements are possible.) Connecting unit 20, which is disposed at the bottom of vehicle seat 200, includes locking pins 21 that are retractable in the vertical direction. Each locking pin 21 can engage with (locked state) or disengage from (unlocked state) the fixing holes 11 based on its extension and retraction. And an operating unit (not shown), which is communicatively connected to connecting unit 20, sends control commands to the locking pins 21 to extend and retract the locking pins 21, thereby controlling the engagement or disengagement of the locking pins 21 with the fixing holes 11.

[0048] The vehicle seat 200 fixing system 1 in this embodiment differs from the traditional seat movement trajectory which is rigidly constrained by a slide rail. In this embodiment, the combination of arrayed fixing holes 11 and retractable locking pins 21 allows the vehicle seat 200 to be flexibly adjusted to any position, such as forward, backward, left, right, and diagonally, on the horizontal plane of the vehicle floor 100, greatly improving the freedom of movement of the vehicle seat 200. At the same time, the operating unit can conveniently control the extension and retraction of the locking pins 21. In the unlocked state, the vehicle seat 200 can be manually pushed to the target position. In the locked state, the locking pins 21 and fixing holes 11 are firmly engaged, ensuring that the vehicle seat 200 has reliable support stability in any fixed position. This solves the limitation of existing vehicle seats 200 that can only slide along a single trajectory, improving the flexibility of the vehicle seat 200's movement and the personalized experience of the occupants.

[0049] The locking pin 21 can be an electromagnetic latch, a spring latch, or the like. The operating unit can be, for example, a microcontroller, which can receive user commands by communicating with unlock / lock buttons or portable terminals located on the side of the vehicle seat 200, and can send lock / unlock signals to the drive mechanism of the locking pin 21 based on user commands by communicating with the drive mechanism of the locking pin 21, thereby controlling the locking pin 21 to lock / unlock the fixing hole 11.

[0050] like Figures 3-5As shown, the connecting unit 20 of the fixing system 1 in this embodiment also includes a support 22 corresponding to the locking pin 21. The support 22 is fixed to the bottom of the vehicle seat 200 and is provided with a receiving hole 23 extending in the vertical direction, in which the locking pin 21 is retractably accommodated, so that when the locking pin 21 is fully retracted into the receiving hole 23, the locking pin 21 is disengaged from the fixing hole 11 (unlocked state, see...). Figure 4 When the locking pin 21 extends from the receiving hole 23, the locking pin 21 engages with the fixing hole 11 (locked state, see...). Figure 5 ).

[0051] The support 22 can be a monolithic columnar component made of high-strength alloy material, balancing structural rigidity and installation compactness. Its upper end, for example, has a flange with radially outwardly extending and evenly distributed mounting holes. Each support 22 is then fixed to the vehicle seat 200 by bolts passing through the mounting holes and tightening them to the lower surface of the vehicle seat 200 frame. Its lower end is a smoothly transitioned support end, with the outer edge... Figure 3 The seat 200 features a rounded chamfer to prevent sharp edges from scratching or jamming against the vehicle floor 100 during seat 200 movement. The support 22 extends perpendicularly to the vehicle floor 100, and its extension length can be configured to ensure that the receiving hole 23 has sufficient depth to fully accommodate the main body of the locking pin 21, the drive mechanism, and the position detection related structures (described later), while also allowing the lower support end of the support 22 to form slight supporting contact with the surface of the vehicle floor 100 in the unlocked state. This prevents other components of the bottom of the vehicle seat 200 from directly rubbing against the vehicle floor 100, and also does not interfere with the extension and retraction of the locking pin 21 or the movement trajectory of the vehicle seat 200. By providing the support 22, stable support is enhanced, the connection strength between the locking mechanism and the vehicle seat 200 is strengthened, ensuring that the vehicle seat 200 does not wobble or shift during dynamic vehicle movement, while also protecting the locking pin 21 from structural damage.

[0052] In the support 22, the receiving hole 23 is a cylindrical through hole extending along the axis of the support 22. The lower end of the receiving hole 23 is open and flush with the end face of the lower end of the support 22. The opening edge of the receiving hole 23 may also be chamfered to guide the locking pin 21 to extend smoothly and avoid scratching the surface of the locking pin 21. The locking pin 21 and the receiving hole 23 are clearance fit. The main body of the locking pin 21 is cylindrical and fits against the inner wall of the receiving hole 23, forming a full-circumference guiding constraint. This ensures that the locking pin 21 can extend and retract smoothly while strictly limiting its radial runout, ensuring accurate movement trajectory. When the locking pin 21 is fully retracted, its lower end retracts into the receiving hole 23, not exceeding the lower end face of the support 22, ensuring complete disengagement from the fixing hole 11; when the locking pin 21 extends, it moves downward along the axis of the receiving hole 23 under the precise guidance of the receiving hole 23, extends out through the lower opening and engages with the fixing hole 11, ensuring precise alignment between the locking pin 21 and the fixing hole 11, and improving the reliability of engagement.

[0053] In the above description, the support 22 is fixed to the frame of the vehicle seat 200 via flanges, etc., and therefore can be installed as a retrofit component into various existing vehicle seats 200 without changing the structure of the vehicle seat 200, thus exhibiting good operability and versatility. However, this is not limiting; of course, the support 22 can also be integrally molded with the frame of the vehicle seat 200.

[0054] Still see Figure 3 In this embodiment, the end of the locking pin 21 is configured as tapered, and the entrance to the fixing hole 11 is also tapered, making the hole diameter larger towards the upper side. Besides tapering, the end of the locking pin 21 can also be configured as hemispherical, etc. By using a tapered or hemispherical end for the locking pin 21 and a tapered structure with a larger upper diameter for the entrance to the fixing hole 11, a suitable guiding fit is formed. This facilitates the insertion of the locking pin 21 into the fixing hole 11, guides the locking pin 21 to accurately engage with the fixing hole 11, improves the alignment success rate, reduces the alignment requirements of manual operation, and makes the fixing operation of the seat 200 more convenient.

[0055] In this embodiment, as Figure 2 As shown, four supports 22 are provided, located at the four corners of the bottom of the vehicle seat 200. The four supports 22 are distributed at the four corners of the bottom of the seat 200, which can achieve balanced four-point support. This can not only evenly distribute the load of the vehicle seat 200 and the occupants to each support 22, effectively suppressing the shaking of the vehicle seat 200 during dynamic driving, but also form a full-range locking constraint through the engagement of the four corner locking pins 21 with the fixing holes 11, preventing the vehicle seat 200 from floating and improving the locking reliability.

[0056] However, it should be noted that the above-mentioned number and placement of supports 22 are merely examples, and can also be adopted in accordance with... Figure 2Different methods are used, for example, other supports 22 are set in addition to the four corners, the supports 22 are set to be at least three or more that can form the three vertices of a triangle, the supports 22 are set in other parts other than the four corners, etc.

[0057] Because the fixing holes 11 of the fixing unit 10 on the side of the vehicle floor 100 are arranged in an array and their arrangement range needs to be larger than the arrangement area of ​​the locking pin 21 to achieve positional changes, some fixing holes 11 may be exposed outside the seat 200. In this case, an elastic sealing cover (not shown) can be provided on the top of each fixing hole 11. The sealing cover is connected to the edge of the fixing hole 11 by a thin spring. When the locking pin 21 moves downward, its end can push open the sealing cover to complete the locking. After the locking pin 21 retracts, the sealing cover automatically resets, so that even if some fixing holes 11 are exposed, it can prevent dust, beverage residue and other debris from entering the holes.

[0058] In the fixing system 1 of this embodiment, to facilitate movement and alignment, the fixing unit 10 may further include multiple position detection sensors. These multiple position detection sensors are configured one-to-one with multiple fixing holes 11, and each position detection sensor is arranged around the edge of the corresponding fixing hole 11. The connecting unit 20 may include inductive triggers corresponding one-to-one with the locking pins 21. The inductive triggers are fixed to the supports 22 of the locking pins 21 and are adapted to the sensing range of the position detection sensors. The operating unit is configured to receive the detection signals from the position detection sensors in real time, and when the inductive triggers move into the sensing range of the position detection sensors, the operating unit outputs an alignment success prompt signal. Based on this configuration, precise alignment detection and intuitive feedback between the locking pins 21 and the fixing holes 11 can be achieved through the coordinated detection between the position sensors and the inductive triggers, as well as the prompt output of the operating unit. This reduces the difficulty of user operation; users do not need to visually confirm or repeatedly test, but can quickly determine the alignment status through sound and light prompts, improving the locking success rate and avoiding problems such as the locking pins 21 getting stuck or unable to engage due to alignment deviations, further enhancing the reliability of the system.

[0059] In addition to the aforementioned position detection sensor, the fixing system 1 may also be equipped with a locking pin status sensor to detect the longitudinal extension and retraction state of the locking pin 21, in order to determine whether the locking pin 21 is fully extended (locked in place) or fully retracted (unlocked in place). Two locking pin status sensors may be axially arranged along the inner wall of the receiving hole 23 of the support 22, one installed in the upper area of ​​the receiving hole 23 (corresponding to the "fully retracted" position of the locking pin 21) and the other installed in the lower area of ​​the receiving hole 23 (corresponding to the "fully extended" position of the locking pin 21). The two sensors can be fixed in the preset mounting groove on the inner wall of the support 22 by an embedded mounting method.

[0060] The above has described in general terms the fixing system 1 for a vehicle seat 200 according to the first embodiment of this disclosure. Below, examples of its use scenarios will be briefly described.

[0061] For example, when a user wants to move the vehicle seat 200 diagonally backward, they first press the "unlock button" on the side of the vehicle seat 200. After receiving the command, the control unit controls the drive mechanism of the locking pin 21 to move, and the locking pin 21 retracts upward along the receiving hole 23 of the support 22. When the locking pin 21 retracts upward... Figure 4 The seat 21 is fully retracted to the upper part of the receiving hole 23, triggering the locking pin status sensor. The operating unit then provides feedback to the user via sound and light, indicating "unlocked in place." At this point, the user can manually push the seat 200 to move it diagonally backward. During this movement, the curved chamfer at the end of the support 22 effectively reduces frictional resistance with the vehicle floor 100, making the movement smooth and effortless, without being constrained by a single trajectory. Simultaneously, the position detection sensor of the fixing unit 10 scans the sensing trigger on the support 22 of the locking pin 21 in real time. When the locking pin 21 moves with the vehicle seat 200 to the target position above the fixing hole 11, the position detection sensor is triggered and sends a signal to the operating unit. The operating unit immediately provides feedback to the user via sound and light, indicating "alignment successful." The user stops pushing the vehicle seat 200 and presses the "lock button." The locking pin 21 extends downward under the precise guidance of the receiving hole 23, its tapered end self-aligning through the tapered entrance of the fixing hole 11 and precisely locking into the fixing hole 11. When the locking pin 21... Figure 5 As shown, the seat extends fully to the lower part of the receiving hole 23. The locking pin status sensor confirms that the seat is locked in place, and the operating unit provides feedback to the user through sound and light, indicating "locking successful". At this time, the vehicle seat 200 has been moved and fixed to the target position at the rear, completing the position movement.

[0062] For example, when a user wants to rotate the vehicle seat 200 slightly clockwise to adjust their seating posture, the operation process is the same as described above: press the "unlock button," and after receiving an unlock prompt, the user can hold the vehicle seat 200 and rotate it slightly clockwise. Since the fixing holes 11 are arranged in an array, during the rotation of the seat 200, it is only necessary to ensure that the four locking pins 21 at the final locking position are aligned with their corresponding fixing holes 11; a specific rotation trajectory is not required. When the target angle is reached and the four locking pins 21 are aligned with the four fixing holes 11 in the array, the position detection sensor is triggered synchronously, informing the user of successful alignment. The user presses the "lock button," and the four locking pins 21 extend synchronously and engage with the fixing holes 11. After the locking pin 21 status sensor confirms that all locking pins 21 are fully extended, it sends a successful locking signal, thus completing the angle adjustment of the vehicle seat 200.

[0063] Similarly, if a user needs to adjust the vehicle seat 200 in other directions (such as diagonally forward, counterclockwise rotation, left or right translation, etc.), it can be achieved through the general process of unlocking, moving / rotating, alignment feedback, and locking. The entire process does not require visual confirmation of alignment. It relies on the dual feedback of the position detection sensor and the status sensor of the locking pin 21, making the operation convenient and precise, and fully meeting the user's personalized needs for adjusting the vehicle seat 200.

[0064] <Second Embodiment>

[0065] Figure 6 This is a schematic diagram showing the connection unit 20 in the fixing system 1 for a vehicle seat 200 according to the second embodiment of the present disclosure.

[0066] The second embodiment of this disclosure is basically the same as the first embodiment, except that, as Figure 6 As shown, in the second embodiment, a ball roller 24 is also provided at the end of the support 22 in the area around the outlet of the receiving hole 23.

[0067] The fixing system 1 of the second embodiment utilizes ball rollers 24 disposed at the end of the support 22 to change the sliding friction between the support 22 and the vehicle floor 100 into rolling friction when the vehicle seat 200 is manually moved. This makes it easier to move the vehicle seat 200. Moreover, the ball rollers 24 disperse the friction load by rotating on their own, effectively avoiding scratches and wear caused by the end of the support 22 making hard contact with the vehicle floor 100, protecting the coating of the vehicle floor 100, further reducing the maintenance cost of the vehicle floor 100 caused by the movement of the vehicle seat 200, and extending the overall service life of the system.

[0068] <Third Embodiment>

[0069] Figure 7 This is a schematic diagram showing the fixing unit 10 in the fixing system 1 for a vehicle seat 200 according to the third embodiment of this disclosure.

[0070] The third embodiment is basically the same as the first and second embodiments, except that, as Figure 7 As shown, in the third embodiment, the fixing system 1 further includes a caster wheel 30, which is disposed at the bottom of the vehicle seat 200 and includes a caster wheel. The lowest point of the caster wheel may be substantially flush with the lowest point of the support 22, or lower than the lowest point of the support 22.

[0071] In the third embodiment, by adding a caster wheel 30, the caster wheel can also be used to support the weight of the vehicle seat 200 and the occupants. Moreover, when the vehicle seat 200 is moved, the frictional resistance of the vehicle seat 200 is further reduced, making it easier and smoother for the vehicle seat 200 to move along any trajectory in the horizontal plane, such as forward, backward, left, right, or diagonal, effectively avoiding jamming or tilting when manually pushed.

[0072] <Variations of the Third Embodiment>

[0073] In the third embodiment, the caster wheel portion 30 may be continuously supported on the vehicle floor 100. However, in this variant, the caster wheel portion 30 of the fixing system 1 may have a storage structure, allowing the caster wheel to switch between a stored state and a used state. In the stored state, the caster wheel is positioned above the lowest point of the support 22, while in the used state, at least the lowest point of the caster wheel is positioned lower than the lowest point of the support 22.

[0074] With the configuration in this variant, the casters can switch between a storage state and a usage state, so that the casters only become active when unlocked to reduce pushing resistance, while automatically disengaging when locked to completely isolate them from the vehicle floor 100, thus extending the service life of the casters.

[0075] <Fourth Embodiment>

[0076] Figure 8 This is a schematic diagram showing the fixing unit 10 in the fixing system 1 for a vehicle seat 200 according to the fourth embodiment of this disclosure.

[0077] The fourth embodiment is basically the same as the first, second and third embodiments, except that the fixing hole 11 of the fixing unit 10 is not directly formed on the vehicle floor 100, but the fixing unit 10 also includes a mounting plate portion 12, which is fixed to the vehicle floor 100, and the fixing hole 11 is formed on the mounting plate portion 12.

[0078] In the fourth embodiment, the mounting plate 12 serves as an integrated carrier for the fixing holes 11 and is fixed to the vehicle floor 100. Thus, the mounting plate 12 can be fixed to the vehicle floor 100 as a whole after prefabrication without the need for complex processing of the floor 100. This adapts to the floor 100 structure of different vehicle models. Furthermore, when the fixing holes 11 are worn or damaged, the mounting plate 12 can be replaced separately without the need to repair the entire vehicle floor 100, reducing maintenance costs. It also allows for flexible adjustment of the array layout of the fixing holes 11 according to the size of the seat 200 and locking requirements, adapting to the installation requirements of different vehicle models and seat 200 specifications.

[0081] Since the vehicle of the fifth embodiment is equipped with the aforementioned fixing system 1, it can also achieve the various technical effects of the aforementioned fixing system 1, which will not be elaborated here.

[0082] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
