Description

Technical Field

[0001] The present invention relates to the technical field of automobile trunks, and in particular to an automobile trunk and a control method thereof. Background Art

[0002] With the continuous improvement of living standards, cars have gradually become an indispensable means of transportation for every family. As a means of transportation, cars have greatly improved travel convenience. At the same time, cars have spacious trunks, which can carry a large amount of luggage. Car trunks are generally rectangular. To meet consumers' demand for more space, trunks are now designed to be larger and larger. However, existing car trunk floors are fixed to the bottom of the car trunk to store luggage. When the trunk is deep, people cannot reach the front of the trunk floor, making it inconvenient to place or remove luggage from the front of the trunk floor.

[0003] At present, there is also the rise of a night market economy, and trunk night markets have become a trend, but because the car trunk is deep and low, it cannot display goods well. Summary of the Invention

[0004] The purpose of the present invention is to provide a car trunk and a control method thereof to solve the problem that the traditional bottom plate is generally fixed, the items on the deep bottom plate are inconvenient for users to access, and the practical performance is not high.

[0005] Technical solution: The present invention provides a car trunk, comprising: a supporting mechanism, a driving mechanism, a trunk floor, and a sliding rail. The supporting mechanism comprises: a bracket, an X-link, fixed blocks are provided at both ends of the bracket, an electromagnetic clutch is provided at the upper end of the X-link, and a magnetic slider is provided at the lower end; the driving mechanism comprises: a lead screw and a driving motor, the lead screw is fixed between the fixed blocks, two lifting control parts and two translation control parts are provided on the lead screw, and the driving motor is arranged at one end of the lead screw; the trunk floor is arranged above the supporting mechanism, and two electromagnetic connecting parts are provided below; the sliding rail is arranged below the X-link and is slidably connected to the magnetic slider.

[0006] Furthermore, in the aforementioned automobile trunk, the electromagnetic clutch is coupled to the lift control member, and the translation control member is coupled to the electromagnetic connector. The lift and translation control members are provided with nuts on the inside that engage with the lead screw, and the lift control member is provided with a gear on the outside that engages with the electromagnetic clutch. Rotation of the lead screw drives the lift control member, which, through the transmission of the outer gear, causes the X-link to retract, driving the bracket upward.

[0007] Furthermore, in the above-mentioned car trunk, the bracket is a galvanized rectangular tube with grooves on the upper and lower sides to ensure that the screw is exposed. The sides of the rectangular tube can protect the screw, and the grooves on the upper and lower sides facilitate the mating of components on the screw with the trunk floor and the support mechanism.

[0008] Furthermore, in the above-mentioned car trunk, the length of the slide rail is 1 / 4 of the lead screw, and an electromagnet is provided on one inner end of the slide rail. The length of the lead screw combined with the electromagnet can control the height of the trunk floor.

[0009] Furthermore, in the aforementioned car trunk, the electromagnetic connectors are respectively disposed at positions 1 / 4 and 3 / 4 of the trunk floor's contact point with the top bracket, near the outer side. This allows for controlling the outward movement of the trunk floor to ensure that the movement distance is 1 / 2 the length of the lead screw, thereby preventing the trunk from tipping over.

[0010] Furthermore, in the above-mentioned car trunk, the lead screw is made of stainless steel, a non-magnetic material.

[0011] Furthermore, in the above-mentioned car trunk, the lifting control component and the translation control component are made of magnetic carbon steel.

[0012] Furthermore, in the above-mentioned car trunk, one of the translation control members is fixed to the outer end of the screw, so that when the trunk floor moves to 1 / 2 of the length of the screw, there are two fixing points to fix the trunk floor, preventing the trunk floor from tipping over.

[0013] Furthermore, in the above-mentioned car trunk, bearings are provided inside the fixing block, and the bearings are connected to both ends of the lead screw to ensure smooth rotation of the lead screw.

[0014] Furthermore, the above-mentioned car trunk also includes the following method:

[0015] S1. When the trunk is opened and items need to be taken out, the start button is pressed, and the electromagnetic clutch at the upper end of the X-link engages, meshing with the external gear of the lifting control component.

[0016] S2, the drive motor starts, the lead screw rotates, and drives the X-link to rise against the bracket. When it rises to the 1 / 4 position of the lead screw, the magnetic slider on the lower end slide is attracted, and the electromagnetic clutch on the X-link is disengaged, and the gear on the electromagnetic clutch can rotate freely;

[0017] S3. The electromagnetic connector on the inner side of the trunk floor is energized and engages the translation control component on the lead screw. The drive motor drives the lead screw to rotate, causing the trunk floor to move outward. When it moves outward by 1 / 2 the length of the lead screw, the drive motor stops. The electromagnetic connector on the outer side now engages the translation control component at the outer end of the lead screw. Simultaneously, the electromagnetic connectors and the translation control component at both ends secure the trunk floor, preventing it from tipping over and making it easier to access and store items.

[0018] S4. After the item is taken or placed, the drive motor is started and rotated in the reverse direction to reset the trunk floor.

[0019] It can be seen from the above technical solution that the present invention has the following beneficial effects: the car trunk and the control method thereof described in the present invention have the advantages of adjustable height and depth, simple structure, safety and reliability, high practicality, and improved travel convenience. It not only ensures the spaciousness of the trunk and can carry a large number of items, meeting consumers' pursuit of large space requirements, but also makes it convenient to take items deeper into the trunk.

[0028] In this embodiment, a bearing is provided inside the fixing block, and the bearing is connected to both ends of the lead screw 21 .

[0029] Example 2

[0030] On the basis of Example 1, in this embodiment, the bracket is a galvanized rectangular tube, and the upper and lower sides of the rectangular tube are grooved to ensure that the lead screw 21 is exposed.

[0031] In this embodiment, the length of the slide rail 4 is 1 / 4 of the lead screw 21 , and an electromagnet 41 is provided on one inner end of the slide rail 4 .

[0032] In this embodiment, the electromagnetic connectors 31 are respectively arranged at the 1 / 4 and 3 / 4 positions of the trunk floor 3 close to the outer side where the trunk floor 3 contacts the top bracket.

[0033] In this embodiment, the lead screw 21 is made of stainless steel, which is non-magnetic, and the lifting control member 211 and the translation control member 212 are made of magnetic carbon steel.

[0034] In this embodiment, one of the translation control members 212 is fixed to the outer end of the lead screw 21 .
