Description

Technical Field

[0001] This invention relates to the field of automotive armrest technology, specifically to an opening and closing control mechanism for the front seat armrest of an automobile. Background Technology

[0002] The front seat armrest, a key component for supporting the elbows of drivers and passengers, consists of the armrest body (the movable part that opens and closes to support the elbows) and the armrest base (fixed between seats to support the movable part). The smoothness and damping feel of the armrest body's opening and closing operation directly affect the interior quality and user experience of the vehicle. In existing technologies, to achieve automatic opening and controllable closing of the armrest body, a combination of torsion spring and damper is typically used: the torsion spring provides the elastic restoring force for opening the armrest body, allowing it to automatically spring up after unlocking; the damper is used to suppress inertial impact during the opening and closing process, preventing the armrest body from springing open too quickly or slamming shut.

[0003] However, existing opening and closing control mechanisms for automotive front seat armrests still have significant technical flaws, making it difficult to meet the demands for refined tactile feedback. Firstly, existing dampers mostly employ a single fluid cavity and a single-viscosity damping medium, whose damping force is significantly affected by ambient temperature. In low-temperature environments, increased fluid viscosity leads to excessive damping force, resulting in a stiff and laborious feel when opening the armrest, and requiring overcoming the torsion spring's rebound force and high damping when closing, making the pressing operation very heavy. In high-temperature environments, decreased fluid viscosity results in insufficient damping force, failing to effectively buffer the armrest's descent speed, easily causing problems such as "slamming" or impact noises, and failing to achieve stable damping output over a wide temperature range, thus affecting the effectiveness of opening and closing control. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9This invention provides an opening and closing control mechanism for a front seat armrest of an automobile, comprising a main body; the main body includes an armrest seat 101, an armrest body 102, and a rotating module connected between the armrest body 102 and the armrest seat 101; the rotating module includes a hinge groove 1101 formed on the top of the armrest seat 101, a rotating shaft 1102 rotatably connected to the hinge groove 1101, and a hinge platform 1104 connected between the rotating shaft 1102 and the armrest body 102; the rotating module also includes a torsion spring 1103 connected between the hinge platform 1104 and the hinge groove 1101. The main body also includes a locking module disposed between the armrest body 102 and the armrest seat 101. This locking module is used to lock the armrest body 102 and the armrest seat 101 together, and works in conjunction with the rotation module and damping mechanism to ensure the structural stability of the seat armrest after it is closed. It also provides a trigger for unlocking the damped opening and closing of the armrest body 102. A torsion spring 1103 is sleeved on the side wall of the rotating shaft 1102. These components are well-known in this technical field and will not be described in detail here. The main body of the device also includes a damping mechanism for providing damping to the rotation of the rotating shaft 1102. The mechanism includes two storage chambers 1202, blades 1205 connected within the storage chambers 1202, and a drive assembly for rotating the blades 1205. The two storage chambers 1202 are respectively filled with a high-viscosity fluid and a low-viscosity fluid. A first flow channel for fluid flow is formed between the blades 1205 and the inner wall of the storage chambers 1202. The drive assembly includes a rotating rod 1203 connecting the storage chambers 1202 and the blades 1205, a driven gear 1204 connected to the rotating rod 1203, and a driving gear 1201 meshing with the driven gear 1204. 01 is connected to the rotating shaft 1102; the damping mechanism also includes a fluid delivery mechanism for extracting and injecting fluid into the two storage chambers 1202, and the fluid delivery mechanism is used to realize the switching and return of fluids with different viscosities. When the armrest body 102 is opened and closed, the blade 1205 can be driven to rotate in the storage chamber 1202 through the drive component. At the same time, the two storage chambers 1202 are filled with high and low viscosity fluids respectively, and the fluid delivery mechanism is used to realize temperature adaptive switching, realize wide temperature range stable damping output, and effectively improve the smoothness of the opening and closing of the seat armrest and the operation feel.

[0029] The main body of the device also includes a mounting cavity 1206 opened at the top of the armrest seat 101, a sinkhole 1301 disposed at the top of the mounting cavity 1206, and a cover plate 1302 detachably connected to the sinkhole 1301; a damping mechanism is disposed in the mounting cavity 1206; the fluid conveying mechanism includes a temporary storage tank 202 disposed in the mounting cavity 1206 and a connecting pipe 201 connecting the temporary storage tank 202 and the storage chamber 1202; the fluid conveying mechanism also includes a pressing plate 203 sliding in the temporary storage tank 202 and a first moving mechanism connecting the pressing plate 203 and the temporary storage tank 202, wherein when the ambient temperature is lower than a preset threshold, the first moving mechanism... The mechanism drives the extrusion plate 203 to slide towards the storage chamber 1202, squeezing the low-viscosity fluid in the temporary storage box 202 into the storage chamber 1202 through the connecting pipe 201, while simultaneously drawing the high-viscosity fluid in the storage chamber 1202 back to the temporary storage box 202. When the ambient temperature is higher than a preset threshold, the first moving mechanism drives the extrusion plate 203 to slide away from the storage chamber 1202, squeezing the high-viscosity fluid in the temporary storage box 202 into the storage chamber 1202, while simultaneously drawing the low-viscosity fluid in the storage chamber 1202 back to the temporary storage box 202, thereby achieving adaptive switching of fluids with different viscosities and ensuring stable output of damping force over a wide temperature range.

[0030] The first moving mechanism includes a fixed plate 301 connected to the temporary storage tank 202, a first iron block 302 connected to the extrusion plate 203, and a first electromagnet 303 connected to the fixed plate 301. The first moving mechanism also includes a first reset component connected between the extrusion plate 203 and the fixed plate 301. When the first electromagnet 303 is energized, it attracts the first iron block 302, causing the extrusion plate 203 to move closer to the fixed plate 301. When the first electromagnet 303 is de-energized, the elastic reset force of the first reset component pushes the extrusion plate 203 away from the fixed plate 301, squeezing the fluid in the temporary storage tank 202 into the storage chamber 1202, facilitating the movement of the extrusion plate 203, thereby achieving precise delivery and adaptive switching of fluids with different viscosities. The first electromagnet 303 and the vehicle... The temperature detection module signal connection can control the on / off state according to the ambient temperature threshold. It is used to control the on / off state according to the ambient temperature to achieve adaptive switching of fluids with different viscosities, ensuring the stability of damping force over a wide temperature range. With 0℃ as the temperature switching threshold, it can achieve adaptive switching between high-viscosity fluids and low-viscosity fluids: When the temperature is 0℃ or below, the first electromagnet 303 is energized, attracting the first iron block 302 and driving the extrusion plate 203 to move, drawing the high-viscosity fluid in the storage chamber 1202 back to the temporary storage box 202, while simultaneously squeezing in the low-viscosity fluid, to avoid excessive damping at low temperatures; When the temperature is above 0℃, the first electromagnet 303 is de-energized, and the first reset component pushes the extrusion plate 203 to reset, squeezing the high-viscosity fluid into the storage chamber 1202, while simultaneously drawing in the low-viscosity fluid, to ensure the stability of damping force from room temperature to high temperature range, and to avoid impact noise on the handrail body 102. This temperature-linked control enables precise delivery and switching between two types of viscosity fluids, achieving stable output of damping force over a wide temperature range. The high-viscosity fluid thickens rapidly below 0°C, resulting in a sharp increase in damping force; while above 0°C, its viscosity changes gradually, adapting to damping requirements at ambient temperatures of 0-35°C and high temperatures above 35°C. Using only two types of fluids, high and low viscosity can achieve full temperature range adaptation by passing the 0°C threshold, eliminating the need for multiple gear switching. The structure is simple and the control is precise.

[0031] The first reset assembly includes a first sleeve 402 connected to the fixing plate 301, a first sleeve rod 401 connected to the pressing plate 203, and a first spring connecting the first sleeve rod 401 and the first sleeve 402; the first sleeve 402 is sleeved on the side wall of the first sleeve rod 401; the first spring is inserted into the first sleeve 402, the first sleeve 402 is slidably sleeved on the side wall of the first sleeve rod 401, and the first sleeve rod 401 can slide and extend along the axial direction of the first sleeve 402; one end of the first spring abuts against the first sleeve rod 401, and the other end abuts against the first sleeve 402. The inner wall of 402 abuts against the first sleeve 401. When the extrusion plate 203 moves, the telescopic cooperation between the first sleeve rod 401 and the first sleeve 402 guides and constrains the first spring, preventing the first spring from bending or deflecting laterally. This ensures that the extrusion plate 203 moves linearly back and forth in the temporary storage box 202, improving the stability and reliability of fluid delivery and switching. Furthermore, it can apply a pre-tightening force to the extrusion plate 203, thereby applying extrusion force to the fluid. When the fluid in the storage chamber 1202 is lost, it can be replenished in time, ensuring the damping effect and solving the problem of fluid loss.

[0032] The first moving mechanism also includes a detection component for detecting the movement of the extrusion plate 203; the detection component includes a distance sensor 502 and a mounting block 501 connected between the distance sensor 502 and the fixed plate 301. The detection end of the distance sensor 502 is set towards the extrusion plate 203 and is used to collect the distance signal between the extrusion plate 203 and the fixed plate 301 in real time; the distance signal can be fed back to the vehicle control unit to determine the current fluid delivery status and switching progress. Furthermore, by detecting the position of the extrusion plate 203 after it is fully extruded, the fluid loss in the storage chamber 1202 can be determined, providing data for subsequent fluid compensation or maintenance prompts.

[0033] The damping mechanism also includes a plurality of circumferentially evenly distributed arc-shaped blocks 601 connected to the inner wall of the storage chamber 1202; each arc-shaped block 601 includes a tapered arc surface 602; a second flow channel for fluid flow is formed between the blade 1205 and the tapered arc surface 602; the gap of the second flow channel gradually decreases in the counterclockwise direction, and during the later stage of the opening stroke of the handrail body 102, when the blade 1205 rotates counterclockwise, the flow section of the second flow channel gradually narrows. The narrow design gradually increases fluid flow resistance, resulting in a progressively stronger damping force as the opening stroke progresses. This effectively buffers the return force of the torsion spring 1103, preventing the armrest body 102 from rebounding too quickly and ensuring a smooth and stable opening process with stable suspension. Simultaneously, when the armrest body 102 is closed, the blade 1205 rotates clockwise, gradually increasing the gap in the second flow channel. The damping force gradually decreases as the closing stroke progresses, making it easier for the user to overcome the rebound force of the torsion spring 1103 to complete the pressing operation, achieving a balance between slow descent buffering and rapid return to position.

[0034] The damping mechanism also includes a scraping assembly for scraping fluid within the storage chamber 1202; the scraping assembly includes a mounting groove 701 formed at the end of the storage chamber 1202, a scraper 702 disposed within the mounting groove 701, and a second moving mechanism connecting the scraper 702 and the storage chamber 1202; an arc-shaped block 601 is connected to the end of the mounting groove 701; the scraper 702 is sleeved on the side wall of the arc-shaped block 601; the scraping assembly also includes a clearance groove 703 formed on the side wall of the scraper 702, allowing the scraper 702 to slide within the clearance groove 703, and under the drive of the second moving mechanism, the scraper 702 reciprocates along the side wall of the arc-shaped block 601. The residual fluid on the inner wall of storage chamber 1202, blade 1205, and surface of arc block 601 is scraped off to prevent the mixing of fluids of different viscosities, ensuring thorough fluid switching and accurate damping adjustment. At the same time, the scraping action can assist the rapid return of fluid, improve fluid transport efficiency, and extend the service life of the damping mechanism. The scraper 702 adopts a sealed fit structure with the arc block 601, blade 1205, and inner wall of storage chamber 1202. While scraping off residual fluid, it can effectively prevent fluid leakage from the scraping gap. Since the scraper 702 is relatively thin, the small amount of fluid residue in the clearance groove 703 is negligible and does not affect the damping adjustment accuracy.

[0035] The second moving mechanism includes a moving block 802, a connecting rod 801 connecting the moving block 802 and the scraper 702, and a second reset assembly connecting the moving block 802 and the storage chamber 1202. The second moving mechanism also includes a second electromagnet 804 connected to the storage chamber 1202 and a second iron block 803 connected to the side wall of the moving block 802. The connecting rod 801 is provided through the end of the storage chamber 1202. The through part of the connecting rod 801 and the storage chamber 1202 adopts a sealed structure to avoid fluid leakage. At the same time, under the drive of the moving block 802, it can slide linearly along the end of the storage chamber 1202, and stably transmit power to the scraper 702 to ensure the synchronicity and reliability of the scraping action.

[0036] The second reset assembly includes a second sleeve 902 connected to the end of the storage chamber 1202, a second sleeve rod 901 connected to the moving block 802, and a second spring connected between the second sleeve rod 901 and the second sleeve 902. The second sleeve 902 is sleeved on the side wall of the second sleeve rod 901. The second spring is inserted into the second sleeve 902, and the second sleeve 902 is slidably sleeved on the side wall of the second sleeve rod 901. The second sleeve rod 901 can slide and extend along the axial direction of the second sleeve 902. One end of the second spring abuts against the second sleeve rod 901, and the other end abuts against the inner wall of the second sleeve 902. When the moving block 802 moves, the extension and retraction of the second sleeve rod 901 and the second sleeve 902 guides and constrains the second spring, preventing the second spring from bending or deflecting laterally, ensuring the linear reciprocating motion of the moving block 802, and applying a preload to the moving block 802 to ensure that the scraper 702 is reset in place, thereby improving the stability of the scraping effect.

[0037] The damping mechanism also includes a mounting bracket 1001 connected between the two storage chambers 1202 and a slot 1002 opened on the side wall of the mounting bracket 1001. The mounting bracket 1001 is detachably connected to the side wall of the mounting cavity 1206 by bolts, which facilitates installation, disassembly and maintenance, and improves the compactness and integration of the overall structure.

[0038] Working principle: When the handrail body 102 is opened, it is first unlocked. The rotating shaft 1102 can rotate under the action of the torsion spring 1103. At the same time, the handrail body 102 is driven to rotate upward through the hinge platform 1104 to open. When the handrail body 102 is closed, it is pressed to rotate downward to close. The torsion spring 1103 deforms. At the same time, when the rotating shaft 1102 rotates, it can drive the drive gear 1201 to rotate and drive the driven gear 1204 to rotate. Then, through the rotating rod 1203, it drives the blade 1205 to rotate in the storage chamber 1202, which can push the fluid to flow through the first flow channel and form a damping effect. This achieves damped opening and closing control of the handrail body 102, which is more stable and reliable.

[0039] Furthermore, the damping can be adjusted according to temperature. When the temperature is low, the first moving mechanism drives one of the extrusion plates 203 to move away from the fixed plate 301, thereby extruding the low-viscosity fluid temporarily stored in one of the temporary storage boxes 202 and allowing it to enter one of the storage chambers 1202 through the connecting pipe 201. At the same time, the first moving mechanism drives another extrusion plate 203 to move closer to the fixed plate 301, allowing the high-viscosity fluid in the other storage chamber 1202 to be extracted through the connecting pipe 201 and temporarily stored in the other temporary storage box 202. Similarly, when the temperature is high, the high-viscosity fluid is squeezed into the storage chamber 1202 and the low-viscosity fluid is extracted into the temporary storage box 202 for temporary storage. This prevents the damping from being too heavy at low temperatures and too weak at high temperatures, thus achieving adaptive damping for different temperature ranges and improving the effect of damping-type opening and closing control.

[0040] When the armrest body 102 is opened, the drive gear 1201 is driven to rotate clockwise via the rotating shaft 1102, and the blade 1205 is driven to rotate counterclockwise via the driven gear 1204 and the rotating rod 1203. In the initial opening section, between 0-30°, the blade 1205 pushes the fluid through the first flow channel. At this time, the damping is small, and it is easy to open. In the later opening section, between 30°-90° when fully open, the blade 1205 rotates to the position that matches the waist-curved surface 602, and pushes the fluid through the second flow channel. The gap between the blade 1205 and the waist-curved surface 602 gradually decreases. At this time, the damping increases, and the slow rise prevents impact. Similarly, when closing, the user manually presses to overcome the rebound force of the torsion spring 1103, and with the help of the damping cavity contour, achieves a slow descent buffer from 90° to 30° and a quick return to the original position from 30° to 0°. This avoids hitting the hand and allows for easy and complete closure, making the damping opening and closing control more effective.

[0041] When the fluid in the storage chamber 1202 is extracted, the second electromagnet 804 is energized, attracting the second iron block 803. This causes the moving block 802 to move closer to the storage chamber 1202, and the second sleeve rod 901 slides into the second sleeve 902. The second spring is compressed, and simultaneously, the scraper 702 is moved via the connecting rod 801. The scraper 702 slides along the side walls of the blade 1205 and the arc-shaped block 601, as well as the inner wall of the storage chamber 1202, thus scraping and cleaning the fluid. The compression process facilitates the complete and rapid entry of fluid into the temporary storage tank 202 for temporary storage, avoiding residue and improving the damping force adjustment effect. When fluid is squeezed into the storage chamber 1202, the second electromagnet 804 is de-energized. At this time, the moving block 802 can move and reset away from the storage chamber 1202 under the action of the second spring, and drive the scraper 702 to move and reset and move into the mounting groove 701 through the connecting rod 801, so that negative pressure is generated in the storage chamber 1202, making the fluid enter the storage chamber 1202 faster.
