Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, and in particular relates to an in-cab controllable electric vehicle door locking system. Background Technology

[0002] In the design of traditional electric tricycles, the door structure is usually relatively simple, and for cost and practicality reasons, a single door design is often used on one side. The locking system of this type of door is generally located at the free end of the door, that is, the side of the door away from the vehicle's hinges. This design is relatively convenient for opening from the outside of the vehicle; the driver or passenger can simply pull the door handle to open the door.

[0003] However, this door lock placement design is not user-friendly when the driver is inside the vehicle, especially when they need to get out urgently or frequently enter and exit the vehicle. Because the door lock is located at the free end of the door, the driver must turn their head in the opposite direction, and sometimes even turn to the side or twist their body to reach the door handle. This not only increases the difficulty and inconvenience of operation, but may also affect the driver's ability to react quickly in an emergency, posing a potential threat to driving safety.

[0004] Furthermore, for vehicles like electric tricycles that frequently need to navigate in confined spaces or complex environments, the ability for the driver to quickly and easily open the doors is particularly important. Traditional door locking systems, because they do not adequately consider the ease of opening from inside the vehicle, thus limiting the user experience and safety of electric tricycles to some extent.

[0005] Therefore, it is necessary to provide a new in-cabin remote-controlled electric vehicle door locking system that allows the driver to easily and quickly open the door from inside the vehicle without having to turn their head or twist their body, thereby improving safety and convenience during driving.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0022] Please see Figures 1 to 5An in-cab remote-controlled electric vehicle door locking system includes a door 1, on which a door lock 2 is installed. The door lock includes a housing 2-1 and a lock cylinder 2-2 installed within the housing. The lock cylinder is opened or closed externally using a key. The lock cylinder is connected to a bolt 2-3, which is the door lock's actuator and directly contacts the door frame. When the bolt extends, the door is locked; when the bolt retracts, the door can be opened. Installing a door lock on the door is a basic safety requirement, ensuring that the door remains closed during driving to prevent passengers from accidentally falling out or unauthorized entry by outsiders. A rear-opening handle 2-4 is provided on the lock housing, providing a means for rear-seat passengers to open the door from the inside. Corresponding to the rear-opening handle, the lock housing has a rear-opening groove 2-41, which works in conjunction with the rear-opening handle to guide the movement of the handle, ensuring smooth operation and preventing the handle from shifting or jamming during operation. The latch is also connected to a manual opening and closing linkage 2-5 extending towards the driver's cab. This linkage design allows the driver to operate the door lock directly from inside the cab without leaving their seat or reaching outside, greatly improving convenience and safety, especially in emergencies where the door can be opened quickly. The linkage also features a front-opening handle 2-51, which serves as the driver's interface for operating the door lock from inside the cab. By operating the front-opening handle, the driver can easily control the locking and opening of the door, enhancing the cab's internal control capabilities.

[0023] In summary, by cleverly incorporating a rear-opening handle and corresponding rear-opening groove into the door lock housing, combined with a manual opening and closing linkage extending towards the driver's cab and a front-opening handle, a dual-control function for the vehicle door locking system is achieved. This system not only retains the convenience of traditional external door opening but also significantly enhances the convenience and safety of opening the door from inside the vehicle for the driver. The driver does not need to turn their head or twist their body; they can easily open and close the door simply by operating the front-opening handle inside the cab, effectively improving operational convenience and emergency response speed during driving.

[0024] In a further preferred embodiment, the inner side of the door is provided with a mounting groove 1-1 along the connecting rod direction. A hollow horizontal frame 3 is installed in the mounting groove, and the connecting rod is inserted into the horizontal frame. A front opening slide groove 3-1 is provided on the frame near the driver's cab, and a front opening lock handle 2-51 connected to the connecting rod is installed in the front opening slide groove. The mounting groove on the inner side of the door provides a stable mounting space for the horizontal frame, allowing the frame to be firmly fixed to the door. The hollow horizontal frame design not only reduces weight but also provides a smooth sliding channel for the connecting rod. The connecting rod is inserted into the frame and connected to the front opening lock handle through the front opening slide groove, enabling convenient control of the door from inside the driver's cab. This design allows the driver to easily operate the lock handle and quickly open or close the door while driving, improving operational convenience and safety. At the same time, the design of the frame and slide groove also ensures the stability and durability of the connecting rod.

[0025] In a further preferred embodiment, the horizontal frame is connected to the vertical frame 4 on the hinge side of the door. This connection forms a stable support structure, significantly improving the overall strength of the door. This structural design enhances the door's resistance to deformation and impact, allowing it to better maintain its shape and stability under external forces. Simultaneously, the reinforced door structure also contributes to improving the overall safety and stability of the vehicle, providing a safer riding environment for passengers. Furthermore, the connection between the horizontal and vertical frames further optimizes the stress distribution on the door, reduces stress concentration, and extends the door's service life.

[0026] Preferably, a door handle 5 is installed on the inside of the door near the front unlocking lever using fasteners. Installing a door handle on the inside of the door near the front unlocking lever provides the driver with more convenient operation. The door handle is securely installed on the door using fasteners, ensuring reliability and stability in use. When the driver needs to open the door, they can directly grasp the door handle and use it in conjunction with the front unlocking lever to easily open the door, improving the convenience and comfort of operation, and also enhancing the overall user experience of the vehicle.

[0027] Preferably, the door handle is located on the outer side of the horizontal frame, and a door handle positioning groove 5-1 is provided on the inner side of the door. The door handle's location on the outer side of the horizontal frame facilitates the driver's grip; the door handle positioning groove on the inner side of the door ensures accurate installation and stability of the door handle. This design improves the ease of use and durability of the door handle, while also making the inner side of the door neater and more aesthetically pleasing.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
