Description

Technical Field

[0001] The present application relates to a cabin door lock for a motorhome, and belongs to the technical field of vehicle locks. Background Art

[0002] Latch assemblies are widely used in current RVs and other equipment. Generally, latch assemblies are installed on related closing parts such as doors, so as to selectively move the closing parts between opening and closing to achieve the effect of opening and locking the door. Especially for RVs, latch assemblies are also required to be operated not only inside the vehicle but also outside the vehicle.

[0003] Among them, for RV hatches, the current hatch locks often have the problem of cumbersome operation. At the same time, for this type of equipment that is often used outdoors, the sealing and waterproof requirements are also high. Simply relying on mechanical sealing or sealing parts is obviously not ideal. Utility Model Content

[0004] In view of this, the present application provides a motorhome cabin door lock, which uses a lever-type force transmission method to achieve light and fast electronic unlocking control, and also gives the device good sealing performance.

[0005] Specifically, the present application is implemented through the following scheme:

[0006] A caravan door lock comprises a base, a solenoid valve, a handle, a presser foot and a lock core assembly, wherein the presser foot is located at the back side of the base, and the handle and the lock core assembly are located at the front side of the base.

[0007] The base is provided with a buckle slot and a through slot, the buckle slot is located at the bottom and the through slot is located at the top.

[0008] The handle comprises a movable end and a connecting end, wherein the connecting end passes through a through slot and is connected to the presser foot; a lock core assembly is installed on the movable end, and the lock core assembly is installed on the handle through a lock core seat, and a sliding latch is arranged in the lock core seat, and the sliding latch is an eccentric block structure.

[0009] A first section is arranged at one end of the presser foot, the first section is connected to the connecting end, a torsion spring is mounted on the first section, and the free ends of the torsion spring are respectively connected to the handle and the presser foot, the handle, the presser foot and the torsion spring form a lever structure that swings relative to the base, and the other end of the presser foot is arranged corresponding to the cabin door.

[0010] The solenoid valve lock pin of the solenoid valve passes through the buckle groove and is arranged corresponding to the sliding latch; a control panel is installed on the side of the solenoid valve facing the handle, an activation button is arranged between the control panel and the handle, and a column is arranged on the inner wall of the handle corresponding to the activation button.

[0011] Before unlocking, the solenoid valve sinks into the buckle groove, and its solenoid valve lock pin is buckled and connected with the sliding latch, so that the solenoid valve lock pin, the sliding latch and the lock core assembly form a locked state, and at the same time, the pressure foot is buckled at the cabin door; when the control panel is energized, the LED light comes on, and the handle is pressed. The force is applied to the activation button through the column, and the button switch on the control panel is turned on, the solenoid valve is energized, driving the solenoid valve to rise, and the corresponding solenoid valve lock pin rises along the buckle groove. The solenoid valve lock pin is initially unlocked, and the key of the lock core assembly is rotated. The lock core assembly drives the sliding latch to rotate. During the rotation of the sliding latch, it simultaneously pushes the solenoid valve lock pin up until the solenoid valve lock pin is completely disengaged from the sliding latch, the sliding latch slides out, the handle is disengaged from the base, the connecting end of the handle rotates around the first section, and the corresponding part of the other end of the pressure foot moves out of the cabin door to complete the unlocking.

[0012] The above device: with the first section as the fulcrum, the handle and the presser foot are respectively placed on both sides of the base, forming a lever structure with the first section and the torsion spring as the fulcrum, the handle as the force application point, and the presser foot as the force receiving point, and the force application is light; in terms of lock control, it is mainly composed of a solenoid valve and a lock core assembly. In use, the control panel is first powered on, and then when the handle is pressed, the column inside the handle will press down on the activation button, and then the button switch on the control panel is started, the solenoid valve is powered on and rises, and the solenoid valve lock pin is initially unlocked; the lock core assembly is rotated by the key, and the sliding latch rotates with the lock core assembly, and the solenoid valve lock pin is further squeezed out along the buckle groove until the solenoid valve lock pin is separated from the buckle groove of the base, completing the electronic unlocking. In this process, the solenoid valve and the base are stably connected through the cooperation of the solenoid valve lock pin and the buckle groove, which prevents the solenoid valve from being detached when it is shaken, and improves the working stability of the solenoid valve, the control panel, and the LED lamp; the cooperation of the activation button and the column between the handle and the control panel improves the compactness of force transmission and also realizes the structural sealing between the installed components.

[0013] Further, as a preference:

[0014] The sliding latch is an eccentric block structure. When the lock core assembly rotates, the torques of the two ends of the sliding latch relative to the electromagnetic valve lock pin are different.

[0015] The solenoid valve lock pin is sleeved with an O-type sealing ring.

[0016] A spring is arranged between the solenoid valve and the base. More preferably, the spring is sleeved on the solenoid valve lock pin. The spring can be a pagoda-shaped spring. The large end of the pagoda-shaped spring is against or fixed on the solenoid valve. The arrangement of the pagoda-shaped spring plays a good buffering role.

[0017] The activation button is installed between the control panel and the column by interference fit, which not only ensures the stability of the installation, but also has a waterproof effect.

[0018] The control panel is provided with a 2-pin power plug for powering on.

[0019] A pressure plate is fixed on the back side of the base, and the electromagnetic valve is located between the pressure plate and the base. The arrangement of the pressure plate well ensures the stability of the electromagnetic valve and the PVB connecting plate and other components connected thereto.

[0020] The control panel is provided with an LED lamp to realize the light aggregation and transmission of the LED lamp. More preferably, a focusing column is tightly mounted on the base, and a light-transmitting hole is provided on the handle. The LED lamp, the light-transmitting hole and the focusing column are arranged correspondingly. The light-transmitting hole is a stepped hole, which is larger toward the focusing column and smaller toward the outer side of the handle, so as to further focus the light while transmitting light.

[0021] The presser foot also includes a second section, which is riveted and fixed to the first section so that the connecting end is stably connected to the first section.

[0022] O-type sealing rings are arranged on both sides of the torsion spring to provide waterproof sealing for the lever part.

[0023] The above device realizes lever-type locking of the hatch portion and realizes waterproof sealing at multiple locations to adapt to outdoor operation. BRIEF DESCRIPTION OF THE DRAWINGS
