Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an electric long slide rail structure for automotive seats with wiring function. Background Technology

[0002] The aforementioned concept of electric long sliding rails for car seats refers to the following: a typical travel range of 40-70cm, a load capacity of 150-300kg, shock resistance meeting ISO16750 standards, and a displacement error of less than 0.5mm. Dynamic wiring between the car body and the seat is of positive significance for the linear speed control and telescopic guidance of car seats that can be adjusted forward and backward as needed.

[0003] Modern car seats, especially in high-end or luxury vehicles, are increasingly equipped with a wide range of functions supported by the vehicle's power supply. Beyond basic features like fore-and-aft sliding, backrest adjustment, and seat rotation, numerous advanced features designed to enhance comfort, health, convenience, and overall functionality are now commonplace. Examples include: multi-mode massage systems such as kneading, wave-like massage, air pressure massage, acupressure massage, and even dedicated massage programs for the neck, shoulders, and lower back; seat ventilation, using fans or ventilators to actively draw or blow air, alleviating summer heat (often found in mid-to-high-end models); zoned temperature control, allowing independent adjustment of heating / ventilation temperatures for the seat and backrest (found in Lexus and Land Rover models); dynamic support adjustment, such as adjusting the strength of side bolsters or lumbar support; optimized pressure distribution, such as adjusting seat cushion firmness via airbags (e.g., Audi's relaxation seats); convenience and intelligence; safety and driver assistance; personalization and luxury features; and special-scenario functions (such as hidden interfaces or one-touch pop-out child seats), and so on. Not all of these functions require a wiring harness connected to the vehicle's power supply.

[0004] If the increasing number of functions and wiring in car seats, forming the aforementioned wiring harness, cannot be effectively controlled, electrical wiring problems such as pulling, bending, tangling, and wear will occur, affecting the proper functioning of the seats.

[0005] Currently, it's not uncommon for a single seat wiring harness to contain twenty or more wires (power supply, CAN bus, LIN bus, analog signal lines, etc.). This number of wires exceeds the capacity of a single wiring harness, such as a single tank track. Especially considering the physical conflicts between different wiring harnesses, high-voltage and low-voltage systems need to be isolated. For example, heating / ventilation requires 12V / 5A and thus thicker wires, while sensor signals like those from the CAN bus require shielding. If they share a single wiring harness channel, electromagnetic interference (EMI) from high-voltage lines could affect signal transmission, and thicker wires could compress thinner wires. Furthermore, differences in flexibility requirements must be considered; for example, power cables require a high cross-sectional area (e.g., typically 2.5mm²).2 The bending radius is large, while the cross-sectional area of ​​the signal line is relatively small (e.g., typically 0.35 mm²). 2 This requires frequent flexible bending. Therefore, mixed laying will cause the wire harnesses to pull on each other during dynamic movement, accelerating wear.

[0006] Considering factors such as mechanical reliability, thermal management, ease of maintenance, and long-term durability, it is generally accepted in the industry that the area occupied by the wire harness in the wiring channel (e.g., within the tank track cavity) should be controlled to less than 70%. This is because if the occupied space exceeds 70%, the wires will experience insulation wear and even breakage due to compression. Overfilling, such as exceeding 70%, will force the wire harness to rub against each other at bends, accelerating fatigue. In other words, the fill rate is inversely proportional to the wire harness lifespan. For example, if the fill rate is greater than 90%, the wire harness lifespan will be significantly reduced, even by 50% compared to the expected lifespan. Furthermore, overfilling the wire harness will affect heat dissipation and thermal expansion, and mechanical movement reliability, such as increased static friction leading to jamming, etc.

[0007] In conclusion, the current industry's blind adherence to the design concept of wiring for electric long slide rails can no longer meet the usage requirements of constantly improving and increasingly functional car seats. Therefore, it is necessary to make reasonable improvements. The technical solution to be introduced below is produced in this context. Utility Model Content

A lower hinge head hinge seat 2212 extends from the lower right side of the main link unit 221, and this lower hinge head hinge seat 2212 forms a main link unit lower hinge head hinge seat hole 22121. A main link unit upper hinge head 2213 extends from the upper left side of the link unit 221, while a main link unit lower hinge head 2214 extends from the lower left side. The middle region of the main link unit 221 is configured as a hollow main link unit wire harness receiving cavity 2215, which communicates with the aforementioned rear wire harness cavity 35b of the hanger. At the bottom of the main link unit 221, a main link unit guide slider 2216 is configured to form a sliding pair with the aforementioned rear guide platform 113 of the support block. The first main link unit 221 of the main link unit 221 that forms the second wire harness receiving device 22 is located at the end facing the aforementioned hanger 3. The hinge seat hole 22111 of the main link unit 221 is hinged to the upper hinge head 3421 of the main link unit, while the hinge seat hole 22121 of the lower hinge head of the first main link unit 221 is hinged to the lower hinge head 3431 of the main link unit. The upper facing sides of each pair of adjacent main link units 221 are hinged to each other by the upper hinge head hinge seat 2211 and the upper hinge head 2213 of the main link unit, while the lower facing sides of each pair of adjacent main link units 221 are hinged to each other by the lower hinge head hinge seat 2212 and the lower hinge head 3431 of the main link unit. The upper and lower parts of the last main link unit 221 at the left end of the second wire harness receiving device 22 are respectively hinged to the redundant wire harness receiving and storage box through the upper hinged shaft head 2213 and the lower hinged shaft head 2214 of the main link unit. The space between each pair of adjacent main link units 221 forms the main link unit turning clearance opening 222. The wire harness is introduced from the redundant wire harness receiving and storage box and passes sequentially through the main link unit wire harness receiving cavity 2215, the wire harness cavity 35b of the aforementioned connector, and the transition cavity 35c, until it is led out from the aforementioned wire harness lead-out cavity 35d.

[0037] from Figure 3 and Figure 4 and combination Figure 1As illustrated, the opening distance of the turning clearance port 222 of the aforementioned main link unit is significantly larger than the opening distance of the turning clearance port 212 of the secondary link unit. This is because, in situations such as turning, the turning radius of the tank chain structure formed by the cyclic connection of multiple main link units 221 is larger than that of the tank chain structure formed by the cyclic connection of multiple secondary link units 211. This principle is similar to the outer and inner tracks at the bends of a track in athletics; otherwise, the consistent extension and retraction of the two track bundles, namely the aforementioned front and rear track bundles, cannot be achieved.

[0038] The front and rear wiring harnesses are led from a relatively concealed location on the vehicle floor, unlikely to be stepped on by a person's feet, to the aforementioned redundant wiring harness storage box. The front and rear wiring harnesses, which are destined for electrical operating controllers located in seat areas such as the seat armrests, front of the seat, and outer side of the seat, are split into two paths (one for the front and one for the rear) or two separate strands, running parallel (the more functions the seat has, the more wires are in the harness). One path originates from the redundant wiring harness storage box and passes through... The secondary link unit harness receiving cavity 2115, the front harness cavity 35a of the connector, and the transition cavity 35c lead out from the opening of the harness lead-out cavity 35d of the connector 3, and to the aforementioned electrical operation controller; another path leads out from the redundant harness storage box sequentially through the main link unit harness receiving cavity 2215, the rear harness cavity 35b of the connector, and the transition cavity 35c, and to the opening of the harness lead-out cavity 35d of the connector 3, and also to the aforementioned electrical operation controller. If the passenger needs to adjust the car seat forward or backward (taking the actual usage direction in the car as an example), they can simply operate the switch on the electrical operation controller, such as a touch button (the touch button for seat forward / backward adjustment usually has a double-headed arrow), using the conventional operating method. Similarly, when activating the heating function, back massage function, etc., the passenger can select the button on the electrical operation controller as needed, as the panel of the electrical operation controller displays prompts for using the corresponding function.

[0039] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
