Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to a pull-type automobile door lock. Background Art
[0002] In the current automotive technology field, the design and functionality of car door locks have always been one of the key factors to ensure user convenience and safety. However, in extreme climatic conditions, especially in extremely cold, rainy and snowy weather, traditional car door lock systems face severe challenges. Specifically, the exterior door handles become difficult to operate due to snow and ice, or even completely freeze, making it difficult to open the door. This problem greatly affects the user experience and vehicle accessibility in emergency situations.
[0003] The Chinese patent publication number is: CN220395432U discloses a car door lock, including a car door, a hidden groove is provided on the car door, a door handle is rotatably installed in the hidden groove, a heat-conducting rubber ring is installed at the edge of the inner cavity of the door handle, and a heating wire is installed on the heat-conducting rubber ring. The controller converts the electrical signal into an instruction to turn on the power supply socket, and the instruction is transmitted to the power supply socket through the second circuit. When the power supply socket is turned on, a complete circuit is formed between the battery module in the power supply socket and the heating wire. The heat emitted by the heating wire is transmitted to the heat-conducting rubber ring, and the heat-conducting rubber ring then transmits the heat to the door handle housing. The heat emitted by the door handle itself melts the ice. When the user touches the opening button, the door handle can pop out from the hidden groove.
[0004] Although the above patent solves the problem that the door handle cannot be opened under frozen conditions, it still has certain shortcomings. First, the strategy of fully heating the door handle means that a large power supply is required, which directly increases the dependence on the battery in the handle. In a low temperature environment, the battery performance itself will decline, and the additional power consumption will undoubtedly increase the pressure on the battery. Secondly, due to the need for continuous heating, the heating battery inside the handle quickly runs out of power. Frequent battery replacement or charging not only brings economic burden to users, but also causes more inconvenience. Therefore, it is necessary to propose a pull-type car door lock to solve the above-mentioned problems. Utility Model Content
[0005] In view of the problems in the related technology, the utility model provides a pull-type automobile door lock to overcome the above technical problems existing in the existing related technology.

[0007] A pull-type automobile door lock comprises a door plate, a pull groove is formed on the surface of the door plate, a handle shell is installed on one side of the pull groove, a lock hole is fixedly installed on one side of the handle shell, a lock core is fixedly installed on one side of the lock hole, an ice-breaking mechanism is provided on one side of the handle shell, and a heating mechanism is fixedly installed on one side of the ice-breaking mechanism.
[0008] Furthermore, in order to realize the power transmission of the ice-breaking mechanism, the ice-breaking mechanism includes a support frame fixedly installed on one side of the inner wall of the handle shell, a transmission rod is rotatably installed on the top of the support frame, a contraction groove is opened on the surface of the handle shell, a prying rod is rotatably installed on one end of the transmission rod, and the prying rod is installed in the contraction groove. After the prying rod is turned out from the contraction groove, the prying rod is swung up and down to drive the end of the transmission rod to move up and down.
[0009] Furthermore, in order to break the ice at the connection between the handle shell and the car door, ice-breaking rods are rotatably installed on both sides of the inner wall of the handle shell, and push plates are fixedly connected to the upper and lower sides of one end of the ice-breaking rod. Ice-breaking holes are opened on both sides of the surface of the handle shell, and the push plates cooperate with the ice-breaking holes. A transmission groove is opened at one end of the ice-breaking rod, and one end of the transmission rod is installed in the transmission groove. When the prying rod drives the end of the transmission rod to swing up and down, the transmission groove is squeezed, thereby driving the ice-breaking rod to swing up and down in the handle shell, so that the push block moves up and down in the ice-breaking hole.
[0010] Furthermore, in order to achieve heating and thawing of the lock core, the heating mechanism includes a power supply seat, a battery is installed inside the power supply seat, a controller is fixedly installed on one side of the battery, and an electric heating ring is fixedly installed on the outer surface of the lock core. The lock core is heated by the electric heating ring to thaw the lock core frozen in extremely cold weather to prevent the car door lock from being unable to be opened.
[0011] Furthermore, in order to facilitate the removal of the prying rod from the contraction groove, a removal groove is opened at one end of the contraction groove, and one end of the prying rod can be rotated and removed through the removal groove.
[0012] Furthermore, in order to prevent the prying rod from being frozen in the shrinkage groove and unable to be removed, a heating wire is fixedly installed on one side surface of the prying rod. The frozen prying rod can be heated and melted by the heating of the heating wire, making it convenient to rotate and remove it.
[0013] Furthermore, in order to protect the inner wall of the handle shell, a protective cover is fixedly connected to one side of the handle shell.
[0014] The beneficial effects of the utility model are as follows: when the car door handle is frozen in extremely cold weather, the lock core and the prying rod can be heated by the heating mechanism to melt the ice around them, and after melting, the prying rod is rotated out of the contraction groove to be pried up and down, and the up and down swing of the prying rod drives the end of the transmission rod to squeeze the transmission groove up and down, so that the ice-breaking rods rotatably installed on both sides of the handle shell drive the pushing plates at the end to move up and down, and the ice at the connection between the handle shell and the car door is pushed and broken, and after the car door lock is opened by inserting the key into the lock core, the handle shell can be pulled outwards to open the car door conveniently; the car door lock can break the ice of the frozen car handle without the aid of other tools, the prying rod and the ice-breaking rod are both labor-saving levers, and the operation is simple and labor-saving, and the battery in the handle shell does not need to heat and melt the entire car handle, so the power consumption is small and the efficiency is high, which greatly improves the door lock opening efficiency under extreme conditions.
