Description

Technical Field

[0001] This utility model relates to the field of battery swapping equipment technology for new energy vehicles, specifically a cabin-type track positioning device for battery swapping stations. Background Technology

[0002] As an important way to replenish energy for new energy vehicles, the efficiency and reliability of battery swapping hinge on the precision and automation of the battery replacement process. Currently, mainstream battery swapping stations generally adopt active positioning technology based on a combination of visual recognition and multi-axis servo drive: after the vehicle has initially come to a stop, the system scans the feature points of the vehicle chassis using a high-resolution camera, the industrial control computer calculates the positional deviation, and then drives a large cockpit-type support platform to make millimeter-level fine adjustments along a precision linear guide rail on the ground, so that the battery pack and the working center of the battery swapping robot are precisely aligned. While current mainstream technologies can achieve high positioning accuracy, they have significant inherent drawbacks: First, the system is extremely complex, involving high-precision guide rails, servo motors, reducers, machine vision modules, and multi-level control systems, resulting in high initial investment costs and hindering the widespread deployment of battery swapping stations. Second, precision moving parts are prone to wear and failure under the harsh conditions of high frequency, high load, and dust and vibration at battery swapping stations, posing a challenge to reliability. High maintenance costs and the need for specialized personnel increase the operational burden. Third, the entire positioning process is time-consuming, involving multiple stages such as image acquisition, data processing, and platform servo adjustment, limiting further improvements in battery swapping efficiency. Furthermore, the adaptability of this technology to different vehicle models relies on adjustments to software algorithms, lacking an inherent, mechanically based adaptability.

[0003] Therefore, the industry urgently needs an alternative solution that is simpler in structure, more cost-effective, easier to maintain, and can maintain high reliability and accurate positioning in order to break through the bottleneck of the current battery swapping model's large-scale development. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution: a cabin-type track positioning device for a battery swapping station, including a base and a lifting platform. The lifting platform is provided with a mechanical self-centering mechanism, which includes a V-shaped guide wheel assembly for guiding the vehicle tires to the center position and a locking mechanism for locking the positioned tires.

[0005] Preferably, the V-shaped guide wheel assembly includes two rollers arranged in a V-shape, and the included angle formed by the axes of the two rollers is between 60° and 120°.

[0006] Preferably, the lifting platform has a floating rear wheel baffle at its end, and a pressure sensor for detecting the pressure of the vehicle's rear wheels is provided below the floating rear wheel baffle.

[0007] Preferably, the signal output terminal of the pressure sensor is electrically connected to the controller of the locking mechanism. When the pressure value reaches a preset threshold, the controller controls the locking mechanism to operate.

[0008] Preferably, the lifting platform is a scissor lift platform or a column lift platform.

[0009] Preferably, the base is provided with wheels and a drive motor to move the entire device along the track.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By utilizing the self-guiding characteristics of the V-shaped guide wheel group in the mechanical self-centering mechanism, the vehicle tires automatically center during the driving process, reducing system complexity and control requirements. The floating rear wheel baffle and pressure sensor work together to detect the vehicle's positioning status and form a linkage control with the locking mechanism, improving positioning accuracy and operational reliability. The device adopts a design scheme with a purely mechanical structure, reducing the use of electrical components and improving the durability and maintenance convenience of the equipment in the high-frequency operation environment of the battery swapping station.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1As shown, the cockpit-type track positioning device for the battery swapping station in this embodiment includes a base 1 and a lifting platform 2. The lifting platform 2 is provided with a mechanical self-centering mechanism 3. The mechanical self-centering mechanism 3 includes a V-shaped guide wheel set 31 for guiding the vehicle tires to the center position and a locking mechanism 32 for locking the positioned tires.

[0017] The V-shaped guide wheel assembly 31 includes two rollers arranged in a V-shape, the included angle between the axes of the two rollers being between 60° and 120°.

[0018] The lifting platform 2 is equipped with a floating rear wheel baffle 4 at its end, and a pressure sensor 5 for detecting the pressure of the vehicle's rear wheels is installed below the floating rear wheel baffle 4.

[0019] The signal output terminal of the pressure sensor 5 is electrically connected to the controller of the locking mechanism 32. When the pressure value reaches the preset threshold, the controller controls the locking mechanism 32 to operate.

[0020] Lifting platform 2 is either a scissor lift platform or a column lift platform.

[0021] The base 1 is equipped with a traveling wheel 6 and a drive motor 7 that enable the entire device to move along the track.

[0022] The working principle of this invention is as follows: When the vehicle enters the lifting platform 2, the tires first contact the V-shaped guide wheel assembly 31. Under the mechanical guidance of the V-shaped guide wheel assembly 31, the tires automatically correct their position, achieving lateral self-centering. The vehicle continues to move forward until the rear wheels contact the floating rear wheel baffle 4. The pressure sensor 5 detects changes in pressure value in real time. When a preset threshold is reached, a signal is emitted. Upon receiving the signal, the controller immediately triggers the locking mechanism 32 to securely fix the tires. After positioning is completed, the lifting platform 2 raises the vehicle to the required working height. Simultaneously, the base 1 moves along the track via the walking wheels 6 and the drive motor 7, achieving final precise alignment with the battery swapping robot. Throughout the entire process, precise positioning without complex servo control is achieved through the combined action of a purely mechanical structure and sensors.
