TECHNICAL FIELD
[0001] The utility model relates to vehicle parts technical field, especially a vehicle seat, and simultaneously, the utility model relates to a vehicle applying the seat. BACKGROUND
[0002] In recent years, with the rapid development of the automobile industry and the improvement of people's living standards, the market has higher and higher requirements for the function and riding comfort of automobile seats.
[0003] At present, the armrests equipped on the seats in the market generally include two kinds: integrated large armrests and hand electric small armrests. Among them, the integrated large armrests are connected with the seat cushion, which occupies a large space and cannot move with the backrest. The hand electric small armrests occupy a small space and can rotate relative to the backrest, which is relatively more convenient to adjust and is relatively more popular.
[0004] However, the seat usually has functions such as front and rear adjustment, backrest inclination angle adjustment, armrest adjustment, and the control switches of these moving parts are installed on the armrest for convenient operation, but this will increase the difficulty of wire harness arrangement. The wire harness needs to be fixed and reliably connected within the moving range of the armrest, while avoiding being squeezed or pulled during the movement of the armrest. SUMMARY
[0005] Therefore, the utility model aims at providing a vehicle seat to facilitate wire harness arrangement.
[0006] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0007] A vehicle seat, comprising a seat cushion framework and a backrest framework connected together, and an armrest framework provided on the backrest framework through a rotating shaft;
[0008] The rotating shaft is provided with a first through hole for the wire harness to pass through, the first through hole extends along the axial direction of the rotating shaft, and the first through hole communicates the space in the backrest framework with the space in the armrest framework.
[0009] Further, the vehicle seat further comprises an armrest driving part provided on the backrest framework, and the armrest driving part is in transmission connection with the rotating shaft; under the driving of the armrest driving part, the rotating shaft can drive the armrest framework to rotate relative to the backrest framework.
[0010] Further, the backrest framework is provided with a backrest side plate on the side close to the armrest framework, and the armrest driving part is installed on the backrest side plate through a mounting plate; the mounting plate is provided with a second through hole corresponding to the first through hole, and the second through hole can be passed through by the wire harness.
[0011] Furthermore, the armrest drive unit and the mounting plate are located on the side of the backrest side panel facing away from the armrest frame, and a reinforcing plate is provided on the side of the backrest side panel facing the armrest frame; the armrest drive unit includes a motor that is connected to the rotating shaft, and the power output shaft of the motor passes through the mounting plate and the backrest side panel, and is placed in the shaft hole on the reinforcing plate.
[0012] Furthermore, a cavity is provided between the reinforcing plate and the backrest side plate, and the power output shaft is connected to the rotating shaft through a transmission assembly, with the transmission assembly located within the cavity.
[0013] Furthermore, the transmission assembly includes a drive gear fixed on the power output shaft and a driven gear fixed on the rotating shaft, wherein the drive gear and the driven gear are meshed together.
[0014] Furthermore, the reinforcing plate is provided with a first clearance hole to allow the pivot to move, and a limiting plate is provided on the side of the reinforcing plate facing the armrest frame, and the limiting plate is provided with a second clearance hole to allow the pivot to move; the pivot is provided with an axial limiting part, which passes through the first clearance hole, and both ends of the axial limiting part abut against the backrest side plate and the limiting plate respectively, so as to limit the installation position of the pivot on the backrest frame along the axial direction of the pivot.
[0015] Furthermore, the handrail frame is provided with a handrail mounting component, the handrail frame is sleeved on the pivot through the handrail mounting component, and the handrail mounting component extends along the length direction of the pivot.
[0016] Furthermore, at least one end of the first via is chamfered; and / or,
[0017] The first through hole is provided with a rotary joint for connecting to the wire harness.
[0018] Compared with the prior art, this utility model has the following advantages:
[0019] The vehicle seat of this utility model, by setting a first through hole in the pivot, can realize the connection between the space inside the backrest frame and the space inside the armrest frame. This allows the wiring harness to pass through the first through hole more smoothly, which can reduce the difficulty of wiring harness arrangement, prevent the wiring harness from being exposed on the seat, keep the wiring harness fixed and reliably connected within the range of motion of the armrest, and prevent the wiring harness from being squeezed or pulled during the movement of the armrest, thus better protecting the wiring harness.
[0020] Furthermore, the armrest drive unit is connected to a rotating shaft transmission. When the armrest drive unit is working, it generates driving force and transmits it to the rotating shaft through a transmission mechanism. The rotating shaft, acting as an intermediary, converts the received driving force into rotational motion, thereby causing the armrest frame to rotate relative to the backrest frame. By controlling the armrest drive unit, users can easily adjust the position of the armrest frame to meet different seating needs.
[0021] Additionally, the mounting plate is fixed to the side of the backrest side panel facing away from the armrest frame, and its main function is to serve as a mounting support for the armrest drive unit. By fixing the armrest drive unit to the mounting plate, the stable and reliable operation of the drive unit can be ensured, while preventing interference with other components of the seat. The second through hole on the mounting plate corresponds to the first through hole in the pivot, and together they form a channel for the wiring harness to pass through. This allows the wiring harness to be neatly and orderly passed between the backrest frame and the armrest frame, thereby preventing the wiring harness from becoming messy.
[0022] The reinforcing plate is located on the side of the backrest facing the armrest frame, and its main function is to enhance the strength and rigidity of the backrest side panel. By adding the reinforcing plate, vibrations and impacts generated during armrest drive operation can be effectively resisted, thereby extending the seat's lifespan. The shaft holes in the reinforcing plate provide a passage for the motor's power output shaft, ensuring stable support and accurate positioning of the motor. This helps reduce motor wobbling and noise during operation, improving the overall comfort and reliability of the seat.
[0023] Furthermore, placing the cavity between the reinforcing plate and the backrest side panel provides sufficient space for the transmission components, effectively protecting them and preventing transmission malfunctions or interference caused by other parts. The transmission components include a drive gear and a driven gear. This gear transmission method has high transmission efficiency, reduces energy loss, and has a relatively compact structure, saving space inside the seat and helping to optimize the overall layout and design of the seat.
[0024] The reinforcing plate is equipped with a limiting plate, through which the axial limiting part passes through the first clearance hole, and with both ends of the axial limiting part abutting against the backrest side plate and the limiting plate respectively. This increases the axial arrangement space of the axial limiting part, improves the accuracy of the shaft arrangement, and ensures smooth and stable rotation of the shaft. By setting up handrail mounting components, the stability and reliability of the handrail frame arrangement can be improved.
[0025] The chamfering at at least one end of the first through-hole allows for smoother passage of the wiring harness or other components, reducing the risk of friction and damage. Simultaneously, the chamfer effectively disperses stress at the hole's edge, improving the overall strength and durability of the structure. The inclusion of a rotary joint within the first through-hole reduces wear on the wiring harness, ensuring it maintains connection and signal transmission even when the seat back frame rotates relative to it. This is crucial for enabling armrest adjustment and ensuring the safety and reliability of the wiring harness.
[0026] Another objective of this invention is to provide a vehicle equipped with the vehicle seat described above.
[0027] The vehicle described in this utility model, by applying the aforementioned vehicle seat, can prevent the wiring harness from being exposed on the seat. The wiring harness can remain fixed and reliably connected within the range of motion of the armrest. At the same time, the wiring harness is not easily squeezed or pulled during the movement of the armrest, and the wiring harness is not easily damaged, thus improving the reliability of the vehicle seat.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0048] Example 1
[0049] This embodiment relates to a vehicle seat, which, through the reasonable arrangement of the structure of each component, can reduce the difficulty of wiring harness arrangement and effectively protect the wiring harness, thus having good practicality.
[0050] Based on the above design concept, an exemplary structure of the vehicle seat in this embodiment is as follows: Figure 1 and Figure 2 As shown, in terms of overall structure, the vehicle seat in this embodiment mainly includes a seat cushion frame, a backrest frame 1, and an armrest frame 2.
[0051] The structural diagram of the seat cushion frame is not shown. The structure and connection method of the seat cushion frame and backrest frame 1 can refer to the existing technology. The armrest frame 2 is rotatably mounted on the backrest frame 1 via a pivot 3. In the vehicle seat with the above structure, the armrest frame 2 is connected to the backrest frame 1 via a pivot 3. This design allows the armrest to rotate or be adjusted within a certain range.
[0052] In this embodiment, the axial direction of the rotating shaft 3 extends along the left and right direction of the vehicle. The rotating shaft 3 is provided with a first through hole 301 for the wire harness 5 to pass through. The first through hole 301 extends along the axial direction of the rotating shaft 3 and connects the space inside the backrest frame 1 and the space inside the armrest frame 2.
[0053] Here, the first through-hole 301 allows the armrest-related wiring harness 5, such as control signal lines and power lines, to be easily connected to electronic components or control modules within the backrest frame 1. This facilitates the realization of various functions on the armrest frame 2 and improves the ease of use of the seat. The first through-hole 301 within the pivot 3 fully utilizes the space inside the seat, avoiding the need for additional wiring harness 5 channels on the outside of the seat.
[0054] like Figure 1 , Figure 6 to Figure 8As shown, for the convenience of controlling the rotation of the armrest, as a preferred embodiment, the vehicle seat of this embodiment further includes an armrest driving part provided on the backrest frame 1. The armrest driving part is in transmission connection with the rotating shaft 3, and upon receiving the driving force of the armrest driving part, the rotation of the rotating shaft 3 can drive the armrest frame 2 to rotate relative to the backrest frame 1.
[0055] By connecting the armrest driving part and the rotating shaft 3 in transmission, when the armrest driving part works, it can generate a driving force and transmit it to the rotating shaft 3 through a transmission mechanism. As an intermediary, the rotating shaft 3 converts the received driving force into a rotational motion, thereby driving the armrest frame 2 to rotate relative to the backrest frame 1.
[0056] Through the control of the armrest driving part, the user can conveniently adjust the position of the armrest frame 2 to meet different sitting needs. Such adjustment can be multi-gear or continuously variable, depending specifically on the structural design of the transmission connection between the armrest driving part and the rotating shaft 3 and the control method of the armrest driving part.
[0057] As Figure 1 、 Figure 6 As shown, on one side of the backrest frame 1 close to the armrest frame 2, there is a backrest side plate 101. On the side of the backrest side plate 101 facing away from the armrest frame 2, there is a mounting plate 102 for mounting the armrest driving part. The mounting plate 102 can be specifically fixed to the side of the backrest side plate 101 facing away from the armrest frame 2 by means such as screwing or welding. And the aforementioned armrest driving part is specifically mounted on the side of the mounting plate 102 facing away from the backrest side plate 101, forming a structure where both the armrest driving part and the mounting plate 102 are located on the side of the backrest side plate 101 facing away from the armrest frame 2.
[0058] In the above structure, fixing the mounting plate 102 on the side of the backrest side plate 101 facing away from the armrest frame 2 mainly serves as the installation support for the armrest driving part. By fixing the armrest driving part on the mounting plate 10, it can ensure the stable and reliable operation of the driving part, prevent interference with other components of the seat, and facilitate the overall layout.
[0059] In this embodiment, the cross-section of the mounting plate 102 is in a "U" shape. It is connected to the backrest side plate 101 through flanges on the upper and lower sides, which can increase the contact area between the two, improve the fixing reliability of the mounting plate 102 on the backrest side plate 101, and thus contribute to improving the installation reliability of the armrest driving part.
[0060] To further facilitate the arrangement of the wire harness 5, in a preferred embodiment, the mounting plate 102 is provided with a second through hole 1021 corresponding to the first through hole 301, and the second through hole 1021 allows the wire harness 5 to pass through. In a preferred embodiment, the first through hole 301 and the second through hole 1021 are arranged coaxially to facilitate the arrangement of the wire harness 5. It should be understood that the first through hole 301 and the second through hole 1021 can also be non-coaxial.
[0061] Here, the second through hole 1021 provided on the mounting plate 102 corresponds to the first through hole 301 in the rotating shaft 3, and together they can form a channel for the wiring harness 5 to pass through. This allows the wiring harness 5 to be neatly and orderly passed between the backrest frame 1 and the armrest frame 2, thereby preventing the wiring harness 5 from becoming messy.
[0062] like Figure 3 and Figure 4 As shown, a reinforcing plate 103 is provided on the side of the backrest side panel 101 facing the armrest frame 2. The armrest drive unit includes a motor 4 that is connected to the rotating shaft 3. The power output shaft 401 of the motor 4 passes through the mounting plate 102 and the backrest side panel 101, and is placed in the shaft hole 1031 on the reinforcing plate 103. The motor 4 is preferably a conventional HALL memory motor.
[0063] Here, a reinforcing plate 103 is placed on the side of the backrest side panel 101 facing the armrest frame 2. Its main function is to enhance the strength and rigidity of the backrest side panel 101. By adding the reinforcing plate 103, the vibration and impact forces generated during the operation of the armrest drive unit can be effectively resisted, thereby extending the service life of the seat. The shaft hole 1031 opened on the reinforcing plate 103 provides a passage for the power output shaft of the motor 4 and ensures the stable support and accurate positioning of the motor 4. This helps to reduce the shaking and noise of the motor 4 during operation and improves the overall comfort and reliability of the seat.
[0064] Depend on Figure 3 to Figure 5 Combination Figure 7 and Figure 8 As shown, a cavity 104 is provided between the reinforcing plate 103 and the backrest side plate 101. The aforementioned power output shaft 401 and the rotating shaft 3 are connected by a transmission assembly, which is located within the cavity 104. By placing the cavity 104 between the reinforcing plate 103 and the backrest side plate 101, sufficient space is provided for the transmission assembly, providing better protection and effectively preventing transmission malfunctions or interference caused by other components.
[0065] In a preferred embodiment, the reinforcing plate 103 extends along the height direction of the vehicle, so that the cavity 104 between the reinforcing plate 103 and the backrest side plate 101 is large and the cavity 104 can extend along the height of the vehicle, thereby better strengthening the structural strength of the backrest side plate 101.
[0066] In this embodiment, the armrest drive unit may include, for example, a linear motor, a cylinder, and a motor 4 that outputs rotational power. The aforementioned transmission component is connected between the armrest drive unit and the rotating shaft 3, which can convert the power of the armrest drive unit into the rotational driving force of the rotating shaft 3.
[0067] In a specific implementation, the handrail drive unit is, for example, a motor 4, and the transmission assembly includes a drive gear 601 fixed on the power output shaft and a driven gear 602 fixed on the rotating shaft 3, and the drive gear 601 and the driven gear 602 are meshed and connected.
[0068] In this embodiment, the transmission component includes a driving gear 601 and a driven gear 602. This gear transmission method has high transmission efficiency, can reduce energy loss, and has a relatively compact structure, which can save space inside the seat and help optimize the overall layout and design of the seat.
[0069] In a preferred embodiment, the driven gear 602 in this embodiment is a sector gear, and the diameter of the driven gear 602 is larger than the diameter of the driving gear 601, so as to provide a suitable rotation speed for the rotation of the handrail frame 2 and facilitate the overall arrangement.
[0070] like Figure 3 to Figure 4 and combined Figure 7 and Figure 8 As shown, the reinforcing plate 103 is provided with a first clearance hole 1032 for the rotating shaft 3, and a limiting plate 105 is provided on the side of the reinforcing plate 103 facing the handrail frame 2, and the limiting plate 105 is provided with a second clearance hole 1051 for the rotating shaft 3.
[0071] The rotating shaft 3 is provided with an axial limiting part 302, which passes through the first clearance hole 1032 and the two ends of the axial limiting part 302 abut against the backrest side plate 101 and the limiting plate 105 respectively. This arrangement can limit the installation position of the rotating shaft 3 on the backrest frame 1 along the axial direction of the rotating shaft 3.
[0072] In terms of specific structure, the axial limiting part 302 can be, for example, a collar formed on the rotating shaft 3. In addition, the axial limiting part 302 can also be a plurality of protrusions provided on the rotating shaft 3. For example, a plurality of protrusions are provided at the part of the rotating shaft 3 that abuts against the backrest side plate 101. The plurality of protrusions are arranged circumferentially around the rotating shaft 3 at intervals. A plurality of protrusions are also provided at the part of the rotating shaft 3 that abuts against the limiting plate 105. These protrusions are also arranged circumferentially around the rotating shaft 3 at intervals. This can achieve the function of axially limiting the rotating shaft 3.
[0073] In the above structure, a limiting plate 105 is provided on the reinforcing plate 103, and the axial limiting part 302 passes through the first clearance hole 1032, and the two ends of the axial limiting part 302 abut against the backrest side plate 101 and the limiting plate 105 respectively. This can increase the axial arrangement space of the axial limiting part 302, improve the accuracy of the arrangement of the rotating shaft 3, and ensure that the rotating shaft 3 rotates smoothly and steadily.
[0074] In this embodiment, the armrest frame 2 is driven by a HALL memory motor, and is controlled by the same seat memory module as the seat backrest adjustment motor. By calibrating the number of HALLs, the seat memory module identifies the tilt angle of the seat back.
[0075] When the armrest is opened, the seat memory module simultaneously reads the HALL status of the armrest adjustment motor and calculates the angle. The seat memory module processes the HALL values fed back from motor 4 and the backrest adjustment motor, actively matches the corresponding power mode, and supports motor 4 to perform corresponding actions so that the armrest can remain horizontal when the backrest rotates, thereby improving the level of automation and riding comfort.
[0076] In addition, when the car door is opened to a certain angle, the handrail can be automatically raised to facilitate passengers getting on and off the vehicle. When the car door is closed, the handrail is lowered for use, as per existing technology.
[0077] As a preferred implementation method, such as Figure 2 As shown, the handrail frame 2 is provided with a handrail mounting component 202, which is sleeved on the pivot 3. The handrail mounting component 202 extends along the length of the pivot 3. By providing the handrail mounting component 202 and extending it along the length of the pivot 3, the stability and reliability of the handrail frame 2 arrangement can be improved.
[0078] In a preferred embodiment, a transmission structure is provided between the handrail mounting component 202 and the rotating shaft 3. The transmission structure is used to drive the rotating shaft 3 to rotate the handrail frame 2. As in this embodiment, the handrail frame 2 specifically includes a plate-shaped handrail body 201. The handrail body 201 is provided with a through hole, and the handrail mounting component 202 passes through the through hole of the handrail body 201, and the two are welded together.
[0079] The inner hole of the handrail mounting component 202 and the mounting portion on the rotating shaft 3 for mounting the handrail mounting component 202 are designed with a regular hexagonal cross-section. Thus, the handrail mounting component 202 is fitted onto the rotating shaft 3, allowing the rotating shaft 3 to drive the handrail frame 2 to rotate. It should be understood that other structures can also be used between the handrail mounting component 202 and the rotating shaft 3, such as a square cross-section fit, spline fit, or welded connection.
[0080] As a preferred implementation method, such as Figure 8As shown, both ends of the first via 301 are chamfered, which can be either rounded or right angled, preferably rounded. It should be understood that it is also possible to provide a chamfer only at one end of the first via 301.
[0081] In the structure described above, a chamfer is provided at at least one end of the first via 301, which makes it easier for the wire harness 5 or other components to pass through the first via 301, reducing the risk of friction and damage. At the same time, the chamfer can also effectively disperse the stress at the edge of the hole, improving the overall strength and durability of the structure.
[0082] To reduce wear on the wiring harness 5, a rotary connector for connecting the wiring harness 5 is provided in the first through hole 301. By providing a rotary connector in the first through hole 301, wear on the wiring harness 5 can be reduced, allowing the wiring harness 5 to maintain connection and signal transmission even when the seat back frame 1 rotates relative to it. This is crucial for enabling the armrest adjustment function and ensuring the safety and reliability of the wiring harness 5.
[0083] In this embodiment of the vehicle seat, by providing a first through hole 301 in the pivot 3, the space inside the backrest frame 1 and the space inside the armrest frame 2 can be connected. This allows the wiring harness 5 to pass through the first through hole 301 more smoothly, reducing the difficulty of arranging the wiring harness 5, preventing the wiring harness 5 from being exposed on the seat, and keeping the wiring harness 5 fixed and reliably connected within the range of motion of the armrest. At the same time, it prevents the wiring harness 5 from being squeezed or pulled during the movement of the armrest, thus facilitating the arrangement of the wiring harness 5.
