Description

Technical Field

[0001] This utility model relates to the field of RV technology, and in particular to an electric lifting mechanism with a magnetic structure. Background Technology

[0002] As a carrier of travel culture, RVs are becoming increasingly popular. When choosing to travel in an RV, the convenience of raising and lowering the RV roof, a common feature, greatly impacts the travel experience. Therefore, electric pop-up roof mechanisms are particularly important. However, existing electric pop-up roof mechanisms for RVs share some common problems:

[0003] 1. The existing RV roof has four movable latches at the front and rear ends of the upper and lower frames. When the RV is not in use or during a trip, the movable latches are closed. When it is necessary to raise or lower the roof, the movable latches connecting the upper and lower frames of the roof must be opened first. Since the latches are located high up, it is necessary to use a ladder and manpower to achieve this, which causes great inconvenience to people's travel.

[0004] 2. If the movable latch connecting the upper and lower frames of the canopy is not released, the electric canopy lift will malfunction due to overload when raising or lowering the canopy.

[0005] 3. The spare elevator occupies the space of the RV, and there are also certain safety hazards for operators when using the elevator. Summary of the Invention

[0006] To address the technical problem that existing RV roof lifting mechanisms are complex and require additional operation to unlock the latches, this utility model provides an electric roof lifting mechanism with a magnetic structure that can be operated with a single button.

[0007] This utility model provides an electric lifting mechanism with a magnetic structure, which includes an electric lifting top seat and an electric lifting base. An electromagnet assembly is provided between the electric lifting top seat and the electric lifting base. The electromagnet assembly includes a magnetic device and a soft iron. The magnetic device is installed at both ends of the electric lifting top seat or the electric lifting base, and the soft iron is installed at both ends of the electric lifting base or the electric lifting top seat opposite to the magnetic device. The magnetic device is a de-energized electromagnet.

[0008] Preferably, the electric lifting mechanism is equipped with a control system, the magnetic device is equipped with an electrical control system, and the control system of the electric lifting mechanism and the electrical control system of the magnetic device are integrated as a whole.

[0009] Preferably, an adjustment device is provided between the magnetic device and the electric lifting top seat or the electric lifting base, one end of the adjustment device is screwed to the magnetic device, and the other end of the adjustment device is fixed to the electric lifting top seat or the electric lifting base.

[0010] Preferably, the adjusting device is provided with a joint bearing, the magnetic device is screwed to the joint bearing, and the joint bearing is able to rotate freely.

[0011] Preferably, the adjusting device is further provided with a screw, one end of which is screwed to the spherical bearing, and the other end of which is fixed to the electric lifting top seat or the electric lifting base.

[0012] Preferably, the adjusting device is further provided with a locking nut, which is mounted on the screw.

[0013] Preferably, the soft iron is screwed to the electric lifting base or the electric lifting top seat.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model eliminates the movable latch connecting the upper and lower frames of the canopy. Instead, it adopts an electromagnetic adsorption structure and uses an automatic control system to lock and open the electric lifting mechanism. This not only eliminates the need for a spare elevator, saving space in the RV, but also eliminates the need for manual operation, greatly facilitating RV travel.

[0016] 2. This utility model uses a de-energized magnet and integrates the electromagnet's electrical control with the electric lifting mechanism's control system, ensuring that the electromagnet control and the electric lifting mechanism control are matched. When the electric lifting mechanism needs to be opened, the electromagnet is energized, the electromagnetic attraction force is eliminated, the lock is released, and the electric lifting mechanism can move up and down normally. When the lifting mechanism needs to be locked, the power is cut off after the lifting mechanism has fully lowered, the electric lifting electromagnet loses power and generates an attraction force, and the magnet locks the lifting mechanism.

[0017] 3. The magnetic structure of this utility model is equipped with an adjustment device, which can adjust the height and angle of the magnet. The electromagnet on the top seat and the soft iron on the base can be completely attracted to each other, generating the maximum attraction force, thereby making the electric lifting top seat and the base firmly locked.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, so that those skilled in the art to which the present invention pertains can easily implement the present invention.

[0024] Example: Figure 1-3 As shown, this utility model includes an electromagnet assembly 100 on the electric lifting mechanism, comprising an electromagnet 110, a spherical bearing 120, a screw 130, a locking nut 140, and a soft iron 150. The upper end of the electromagnet 110 is screwed to the lower end of the spherical bearing 120, and the upper end of the spherical bearing 120 is screwed to the lower end of the screw 130. The upper end of the screw 130 is welded to the electric lifting base. The locking nut 140 is mounted on the screw 130 and can rotate and move up and down on the screw 130. The soft iron 150 is connected to the electric lifting base by screws. The control system of the electric lifting mechanism is integrated with the electromagnet 110's electrical control system.

[0025] Electromagnet 110 is a de-energized electromagnet, and its working principle is the opposite of that of ordinary electromagnets: it remains in an attracted state when power is off and releases when power is on. The reason for using a de-energized electromagnet is to better match the working mode of the electric lifting mechanism. When lifting is required, electromagnet 110 is energized and loses its attraction, releasing the locking of the electric lifting mechanism, which then rises under the action of the drive mechanism. When the lifting mechanism descends, the drive mechanism is de-energized after the electric lifting mechanism has completely fallen. At this time, electromagnet 110 is also de-energized, thereby generating attraction to firmly hold and lock the electric lifting mechanism. Therefore, the electronic control system of electromagnet 110 can be better integrated with the control system of the electric lifting mechanism.

[0026] The spherical bearing 120 can rotate 360° around its axis. When the electric lifting platform lowers, if there is a gap between the electromagnet 110 mounted on the top seat 200 and the soft iron 150 mounted on the base 300, the height of the electromagnet 110 can be adjusted to make it fully fit with the soft iron 150, and then the locking nut 140 can be tightened; if there is an angle between the contact surfaces of the electromagnet 110 and the soft iron 150, the spherical bearing 120 can be adjusted to make the angle between the contact surfaces of the electromagnet 110 and the soft iron 150 match, thereby allowing the electromagnet 110 to generate the maximum attraction force.

[0027] The positions of the screw 130 and the soft iron 150 can be arranged on the electric lifting top seat and the base as needed, and the positions of the screw 130 and the soft iron 150 can also be interchanged.

[0028] The overall installation process of this utility model is as follows: the electromagnet 110 is installed into the spherical bearing 120 and then assembled with the screw 130; the soft iron 150 is installed into the electric lifting base 120, and after the electric lifting is reset, the height of the electromagnet 110 is adjusted so that it is fully in contact with the contact surface of the soft iron 150.

[0029] The overall usage process of this utility model is as follows: After the product is installed, it can be operated via remote control or control switch installed on the RV. When the roof needs to be raised, the electromagnet 110 is energized and loses its attraction. The electromagnet 110 and the soft iron 150 are released, releasing the lock on the electric roof raising mechanism. The electric roof raising mechanism rises under the action of the drive mechanism. When the roof raising mechanism descends, the drive mechanism is de-energized after the electric roof raising mechanism has completely fallen. The electromagnet 110 is de-energized and generates attraction. The electromagnet 110 and the soft iron 150 are attracted together, firmly adsorbing and locking the electric roof raising mechanism.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the claims of the present invention should be within the protection scope of the present invention.
