Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a screen lifting mechanism and its automotive seat. Background Technology

[0002] Currently, many functions of car seats—including backrest tilt, seat cushion height, headrest height adjustment, and lumbar support—are adjustable, all relying on built-in control modules. However, these control modules are mostly located on the center or side armrests, forcing passengers to lean forward to clearly see and operate the interface. This undoubtedly reduces passenger comfort during the adjustment process, as they cannot fully lean back to intuitively experience the effects of the adjustment.

[0003] To enhance passenger convenience and comfort, some car seats are equipped with height-adjustable control screens that can be gently raised to an optimal angle for ergonomic operation when needed. However, existing screen-lifting mechanisms often require significant installation space due to design limitations. This not only increases the complexity of the seat structure but also easily leads to spatial conflicts with other seat components, thus limiting their widespread adoption in practice. Therefore, designing a more compact and efficient screen-lifting mechanism without compromising the overall seat structure and passenger comfort has become a pressing issue. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model aims to provide a car seat armrest screen lifting mechanism that achieves greater compactness and efficiency without affecting the overall structure of the seat and passenger comfort.

[0005] To achieve the above objectives, this utility model proposes a screen lifting mechanism, including a driving mechanism, a supporting body, a screen storage shell, a first shielding member, a second shielding member, and a movable block connected to the driving mechanism. The supporting body is a cavity structure with an open top surface and sliding grooves on both sides. The starting part of the sliding groove is a straight line segment, and the front end of the straight line segment is an upwardly curved arc segment. The driving mechanism is fixed in the cavity of the supporting body. A connecting member is fixedly provided at the bottom rear end of the screen storage shell. The left and right ends of the movable block are hinged to the rear end of the connecting member through a rotating shaft. The rotating shaft extends outward to form a guide shaft and is slidably connected to the sliding grooves on both sides. The front end of the connecting member is also slidably connected to the sliding grooves on both sides through the guide shaft. The driving mechanism can drive the movable block to move back and forth, thereby driving the guide shaft and the connecting member to move along the sliding groove. When the guide shaft slides to the arc segment of the sliding groove, the screen storage shell is lifted upward.

[0006] The first and second shielding components are positioned one behind the other on top of the supporting body. The first shielding component is fixed to the rear end of the screen storage shell, and the second shielding component is fixed to the movable block. The front end of the second shielding component has a clearance opening for the first shielding component to flip upwards. When the screen storage shell is raised, it can cause the first shielding component to flip upwards, allowing it to completely fit into the clearance opening of the second shielding component, thereby shielding the supporting body. In other words, the first and second shielding components, together with the armrest shell, function to conceal gaps when the screen storage shell is raised.

[0007] In the above scheme: the driving mechanism is a lead screw and nut mechanism, and the movable block is fixed on the nut of the lead screw and nut mechanism or integrated with it. When the motor of the lead screw and nut mechanism drives the lead screw to rotate, it can drive the nut to move back and forth. The driving mechanism is simple and easy to assemble.

[0008] In the above solution: the top surface of the screen storage shell is provided with a storage slot for placing the screen.

[0009] In the above scheme, the second shielding component is fixedly connected to the movable block through an intermediate component, which has a simple structure and is easy to assemble.

[0010] This utility model also proposes an automobile seat, including the aforementioned screen lifting mechanism.

[0011] In the above solution: the screen lifting mechanism is installed inside the seat armrest.

[0012] The beneficial effects of this utility model are:

[0013] 1. By integrating components such as the drive mechanism, support body, screen storage shell, and movable block, this solution achieves smooth screen lifting within a limited installation space, avoiding spatial conflicts with other seat structures and improving the overall structural compactness and space utilization of the seat. 2. The slide design combines straight segments and upward-curving arc segments, ensuring a smooth and stable upward lifting of the screen, providing passengers with a comfortable operating experience. 3. The drive mechanism can drive the movable block to move back and forth, thereby moving the connecting parts and screen storage shell along the slide; this design simplifies the operation steps and improves ease of use. 4. After the screen is raised, passengers do not need to lean forward excessively during operation, which helps maintain a good sitting posture and improves riding comfort. Attached Figure Description

[0020] Figure 6 This is a cross-sectional view of the screen lifting mechanism when it is raised. Detailed Implementation

[0021] like Figure 1 As shown in Figure 6, a screen lifting mechanism mainly consists of a driving mechanism 5, a supporting body 2, a screen storage shell 1, a first shielding member 3, a second shielding member 4, and a movable block 8 connected to the driving mechanism 5.

[0022] The supporting body 2 is a cavity structure with an open top surface. It has sliding grooves 7 on both sides. The starting part of each groove 7 is a straight line segment, and the front end of the straight line segment is an upwardly curved arc segment. The driving mechanism 5 is fixed inside the cavity of the supporting body 2. A connector 9 is fixedly installed at the bottom rear end of the screen housing 1. The left and right ends of the movable block 8 are hinged to the rear end of the connector 9 via rotating shafts. The rotating shafts extend outward to form guide shafts 6, which are slidably connected to the sliding grooves 7 on both sides. The front end of the connector 9 is also slidably connected to the sliding grooves 7 on both sides via the guide shafts 6. The driving mechanism 5 can drive the movable block 8 to move back and forth, thereby driving the guide shafts 6 and connectors 9 to move along the sliding grooves. When the guide shaft 6 slides to the arc segment of the sliding groove 7, the screen housing 1 is lifted upwards.

[0023] The first shielding member 3 and the second shielding member 4 are positioned one in front of the other on top of the supporting body 2. The first shielding member 3 is fixed to the rear end of the screen storage shell 1, and the second shielding member 4 is fixed to the movable block 8. The front end of the second shielding member 4 has a clearance opening for the first shielding member 3 to flip upward. When the screen storage shell 1 is raised, it can cause the first shielding member 3 to flip upward, so that the first shielding member 3 completely fits into the clearance opening of the second shielding member 4, thereby achieving the function of shielding the supporting body 2. That is, the first shielding member 3 and the second shielding member 4 cooperate with the armrest shell to cover the gaps when the screen storage shell 1 is raised.

[0024] Ideally, the drive mechanism 5 is a lead screw and nut mechanism, and the movable block 8 is fixed to the nut of the lead screw and nut mechanism or integrated with it. When the motor of the lead screw and nut mechanism drives the lead screw to rotate, it can drive the nut to move back and forth. The drive mechanism is simple and easy to assemble.

[0025] Ideally, the top surface of the screen storage case 1 should have a storage slot for placing the screen.

[0026] Ideally, the second shielding component 4 is fixedly connected to the movable block 8 via the intermediate component 10, which is simple in structure and easy to assemble.

[0027] This utility model also proposes an automobile seat, including the aforementioned screen lifting mechanism.

[0028] Ideally, the screen lifting mechanism should be installed inside the seat armrest.
