Description

Technical Field

[0001] This utility model relates to the field of automotive seat accessories technology, specifically to a slide rail low-temperature resistant starting structure. Background Technology

[0002] Car seat rails are key components installed between the car floor and the seat. Their core function is to allow the seat to be adjusted fore-aft position according to the needs of the occupants, achieving optimal riding comfort and driving posture. Modern seat rails typically integrate a horizontal adjustment mechanism (HDM), which uses a precision gear, rack, or locking mechanism driven manually or electronically to unlock, slide, and lock the rail.

[0003] However, in winter or extremely cold regions, the melting snow and ice brought into the vehicle by passengers' shoes, or moisture already present in the cabin, can seep into the internal cavities of the sliding rail components through the gaps in the fit, particularly on the surfaces of key moving parts such as gears, racks, springs, and locking claws. This moisture freezes into ice once the vehicle is parked. This increases resistance between moving parts, and can even freeze them completely together, preventing the High Horizontal Adjustment Mechanism (HDM) from responding properly to operating commands. Passengers will then be unable to adjust the seat's fore-aft position. For manual sliding rails, the adjustment handle may be impossible to turn or require considerable effort to turn; for electric sliding rails, it may manifest as motor overload, abnormal noise, or even malfunction. This not only significantly impacts normal user experience and deprives the seat of its core adjustment function, but also poses serious safety hazards and inconvenience in emergency situations or when multiple people need to take turns driving.

[0004] Users are typically forced to start the vehicle and turn on the heating system for tens of minutes to several weeks, waiting for the overall temperature inside the cabin (especially the area where the sliding rails are located) to rise above freezing so that the ice inside the rails can slowly melt before the rails can function again. This method is not only time-consuming and energy-intensive, increasing fuel consumption or electricity consumption, but it also cannot provide an immediate response when the seat adjustment function is urgently needed, resulting in a very poor user experience. Utility Model Content

[0005] This utility model aims to solve the technical problems existing in the prior art. In particular, it innovatively proposes a low-temperature resistant starting structure for sliding rails, which can accelerate the response efficiency of seat adjustment function in extremely cold environments as much as possible, thereby improving the environmental adaptability and comfort of the product.

[0006] To achieve the above objectives, this utility model provides a low-temperature resistant starting structure for a slide rail, including an electric heating device disposed on the lower guide rail of the lower slide rail assembly, wherein the electric heating device is disposed away from the upper slide rail assembly, and the controlled end of the electric heating device is connected to the vehicle control system, and is driven to start by the vehicle control system.

[0007] In the above scheme: the electric heating device is an electric heating wire, and a mounting groove for accommodating the electric heating wire is provided on the lower guide rail along its extension direction. The electric heating device is laid along the extension direction of the lower guide rail. Using an electric heating wire reduces the space occupied by the structure, and the mounting groove allows for embedded installation, preventing wear from contact with other devices.

[0008] In the above scheme: there are multiple electric heating devices, which are respectively set on the left and right sides of the lower guide rail. The left and right sides of the lower guide rail are also provided with mounting grooves. The arrangement is reasonable and can heat from both sides at the same time.

[0009] In the above scheme: there are multiple electric heating devices on the left and right sides of the lower guide rail, which are arranged sequentially from top to bottom.

[0010] In the above scheme, the electric heating devices located on the same side are symmetrically arranged with the rotation axis of the pulley of the upper rail assembly as the center of symmetry. They can be arranged around the pulley, the most important component of the upper rail assembly, which can improve the efficiency of the pulley's defrosting and allow it to quickly return to a working state.

[0011] In the above scheme: the electric heating device is located inside the lower guide rail, which can concentrate heat through the inner cavity of the lower guide rail, making it easy for the upper rail assembly of the slide rail to return to a working state as a whole, and is suitable for extremely low temperature conditions.

[0012] In summary, the beneficial effects of this utility model are as follows: the electric heating device activates the seat rail heating function after the vehicle is powered on, quickly raising the rail temperature and restoring the HDM to normal operation, ensuring the rail functions correctly. It can also be combined with the remote start function of modern cars to preheat the rails, allowing passengers to adjust their seats immediately upon entering the vehicle, improving comfort and ensuring timely response of seat adjustment functions. The structure is simple and easy to use, solving the problem of seat rail icing in extremely cold environments, ensuring the HDM maintains immediate and reliable functionality under various climatic conditions, and improving the product's environmental adaptability and user satisfaction.

[0017] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0018] Example 1

[0019] like Figures 1-3 As shown, a low-temperature resistant starting structure for a slide rail includes multiple electric heating devices 3 disposed inside the lower guide rail 2 of the lower slide rail assembly, with the electric heating devices 3 positioned away from the upper slide rail assembly 1. The controlled end of each electric heating device 3 is connected to the vehicle's infotainment system, which drives its start-up. This allows for preheating, leveraging the remote start function of modern automobiles, ensuring that passengers can directly adjust their seats upon boarding, improving comfort and maximizing the responsiveness of seat adjustment functions. The electric heating devices 3, located inside the lower guide rail 2, concentrate heat within the lower guide rail 2's inner cavity, facilitating the overall return of the upper slide rail assembly 1 to a working state, making it suitable for extremely low-temperature conditions.

[0020] In this embodiment, the electric heating device 3 is an electric heating wire. The lower guide rail 2 has a mounting groove 2-1 along its extension direction to accommodate the electric heating wire. The electric heating device 3 is laid along the extension direction of the lower guide rail 2, allowing for embedded installation and preventing wear from other devices. Multiple electric heating devices 3 are respectively arranged on the left and right sides of the lower guide rail 2, and mounting grooves 2-1 are also provided on both sides of the lower guide rail 2. This reasonable arrangement allows for simultaneous heating from both sides.

[0021] Multiple electric heating devices 3 are arranged on both sides of the lower guide rail 2, sequentially from top to bottom. To improve the recovery efficiency of the upper rail assembly 1, the electric heating devices 3 on the same side are symmetrically arranged with the rotation axis of the pulley 1-1 of the upper rail assembly 1 as the center of symmetry. They can be arranged around the pulley 1-1, the most important component of the upper rail assembly 1, to improve the defrosting efficiency of the pulley 1-1, so that it can be quickly restored to a working state and reduce the waiting time for passengers.

[0022] Example 2

[0023] like Figure 4 As shown, the difference between this embodiment and embodiment one is that the electric heating device 3 and the mounting groove 2-1 are both located on the outside of the lower guide rail 2, which facilitates installation or replacement and is suitable for low-temperature conditions.
