Description

Technical Field

[0001] This invention relates to the field of vehicle safety technology, specifically to a multi-functional armrest assembly for a car roof. Background Technology

[0002] With the increasing number of vehicles and the uneven road conditions, accidents occur frequently, and vehicles often encounter situations requiring emergency braking or turning. To prevent passengers from losing their balance and colliding with the front seats or other passengers when the car brakes or turns suddenly, handrails are usually installed on the ceiling above the passenger doors (excluding the driver's seat) so that passengers can maintain their balance.

[0003] For example, CN110303965A discloses a multi-functional armrest assembly for a car roof. This assembly includes a roof side beam module, an armrest module, and a reading light module. The roof side beam module includes a main panel and coat hooks, with the coat hooks rotatably mounted on the main panel. The armrest module is mounted on the main panel and can be pulled out relative to it. The reading light module is mounted on the armrest module and is configured to provide illumination. The multi-functional armrest assembly for a car roof provided by this invention has a compact structure, is securely installed, occupies little space, and offers diverse functions, meeting various passenger needs and improving the passenger experience.

[0004] The patented system uses a ceiling side beam module and an armrest module to ensure a secure installation and minimizes space usage. However, when passengers need to adjust their sitting posture, the armrests are difficult to adjust in angle, making it inconvenient for passengers to grab them. Summary of the Invention

[0005] To address the problem that when passengers need to adjust their seating position, it is difficult for them to grasp the armrests because the angle of the armrests is hard to adjust, this invention proposes a multi-functional armrest assembly for automobile roofs.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a multi-functional armrest assembly for a car roof, comprising an armrest body, wherein a fixing structure is fixedly connected to the rear end of the armrest body;

[0007] The fixing structure includes a connecting component, a fixing component, and a mounting component;

[0008] The connecting component includes a connecting post, which is fixedly connected to the rear end of the handrail body. A ball joint is fixedly connected to the end of the connecting post away from the handrail body. An adjustment groove is provided in the inner cavity of the edge of the ball joint. A top groove is provided in the inner cavity of one end of the adjustment groove. A side groove is provided in the inner cavity of the end of the adjustment groove away from the top groove. The side groove and the top groove are symmetrically arranged about the center of the adjustment groove.

[0009] Preferably, the fixing component includes a fixing cylinder, which is movably connected to the outside of the ball joint. The inner cavity of the fixing cylinder has a polygonal groove, and the inner cavity of the fixing cylinder has a connecting groove, and the connecting groove has a plurality of grooves.

[0010] Preferably, the fixing component further includes a fixing groove, which is formed in the inner cavity of the fixing cylinder. A fixing column is fixedly connected to the inner cavity of the fixing groove, and an adjusting column is movably connected to the inner cavity of the fixing column. An adjusting screw is fixedly connected to the bottom end of the adjusting column, and an adjusting handle is fixedly connected to the end of the adjusting column away from the adjusting screw.

[0011] Preferably, the mounting assembly includes a mounting cylinder, which is fixedly connected to the rear end of a fixed cylinder. A polygonal column is fixedly connected to the inner cavity of the mounting cylinder, and a connecting rod is fixedly connected to the inner cavity of the mounting cylinder.

[0012] Preferably, the mounting cylinder is connected to the fixed cylinder by polygonal columns and connecting rods, and several symmetrically arranged polygonal columns and connecting rods correspond one-to-one with the polygonal grooves and connecting grooves in the inner cavity of the fixed cylinder.

[0013] Preferably, the inner cavity of the mounting cylinder is also provided with a fixing groove, and the fixing groove of the inner cavity of the mounting cylinder and the fixing groove of the inner cavity of the fixing cylinder are each semi-circular, and a fixing column is fixedly connected to the fixing groove of the inner cavity of the mounting cylinder and the fixing column.

[0014] Preferably, two ball joints are symmetrically arranged, and the two symmetrically arranged ball joints are fixedly connected to the rear end of the handrail body through a connecting column.

[0015] Preferably, the armrest body includes a handle, the inner cavity of the handle is fixedly provided with a filling layer, and the rear end of the handle is fixedly connected to an armrest back plate.

[0016] The advantages of this invention are:

[0017] 1. This invention, through the design of the connecting components, allows passengers or other occupants to adjust the armrest if its current position is inconvenient to grasp when adjusting their seating posture and needing to hold onto it. For example, if a passenger in the back seat adjusts their posture by leaning forward or backward and finds the armrest angle unsuitable, they can rotate the adjustment handle to rotate the ball joint, thereby adjusting the armrest position for easier gripping.

[0018] 2. This invention, through the design of the fixing components, allows for the rotation of an adjustment handle to ensure the handrail is securely fixed after the ball joint angle is adjusted. For example, once the ball joint is in place, rotating the adjustment handle clockwise causes the adjustment column to rotate, moving the adjustment screw downwards within the fixing column. This allows the adjustment screw to insert into the top or side groove of the ball joint's inner cavity, thereby fixing the current angle of the handrail and preventing it from wobbling during passenger gripping, ensuring passenger safety.

[0019] 3. Through the design of the armrest body, this invention provides a comfortable grip experience when passengers adjust their sitting posture and grasp the armrest. For example, passengers may sweat when adjusting their posture; the padding layer has a certain sweat-absorbing function, and its soft material can conform to the shape of different passengers' hands, reducing hand fatigue. The back panel of the armrest provides stable support for the grip. During the passenger's gripping process, especially when the passenger grips forcefully, the back panel prevents the grip from deforming, ensuring that the grip can effectively transmit force to the fixed structure, ensuring the reliability of the passenger's grip, and avoiding unstable grip due to grip deformation.

[0029] 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.

[0030] Example 1

[0031] Please see Figures 3-7 As shown, a multi-functional armrest assembly for a car roof includes a fixing structure 2, and the rear end of the armrest body 1 is fixedly connected to the fixing structure 2.

[0032] The fixed structure 2 includes a connecting component 21, a fixing component 22, and a mounting component 23;

[0033] The connecting component 21 includes a connecting post 211, which is fixedly connected to the rear end of the handrail body 1. A ball joint 212 is fixedly connected to the end of the connecting post 211 away from the handrail body 1. An adjustment groove 213 is provided in the inner cavity of the edge of the ball joint 212. A top groove 214 is provided in the inner cavity of one end of the adjustment groove 213. A side groove 215 is provided in the inner cavity of the end of the adjustment groove 213 away from the top groove 214. The side groove 215 and the top groove 214 are symmetrically arranged about the center of the adjustment groove 213.

[0034] When in operation, if a passenger needs to adjust their sitting posture and grab the armrest, and the armrest is in an inconvenient position to grab, the passenger or other passengers can adjust it. For example, if a passenger is sitting in the back and adjusts their posture by leaning forward or backward, and finds that the armrest angle is not suitable, they can turn the adjustment handle 228 to rotate the ball joint 212, thereby adjusting the position of the armrest for easier grabbing.

[0035] Furthermore, the fixing component 22 includes a fixing cylinder 221, which is movably connected to the outside of the ball joint 212. The inner cavity of the fixing cylinder 221 is provided with a polygonal groove 222, and a plurality of polygonal grooves 222 are provided. The inner cavity of the fixing cylinder 221 is provided with a connecting groove 223, and a plurality of connecting grooves 223 are provided.

[0036] During operation, as the ball joint 212 adjusts its angle, the fixed cylinder 221 moves along with the rotation of the ball joint 212. Because the fixed cylinder 221 is movably connected to the ball joint 212, and its internal polygonal groove 222 and connecting groove 223 cooperate with the mounting component 23, the polygonal groove 222 and connecting groove 223 ensure that the fixed cylinder 221 does not disengage from the mounting component 23 during adjustment, maintaining the stability of the overall structure. For example, when the ball joint 212 rotates a large angle, the polygonal groove 222 and connecting groove 223 of the fixed cylinder 221 remain connected to the polygonal post 232 and connecting rod 233 of the mounting component 23, preventing the handrail 1 from becoming loose or falling during adjustment.

[0037] Furthermore, the fixing assembly 22 also includes a fixing groove 224, which is formed in the inner cavity of the fixing cylinder 221. A fixing post 225 is fixedly connected to the inner cavity of the fixing groove 224. An adjusting post 226 is movably connected to the inner cavity of the fixing post 225. An adjusting screw 227 is fixedly connected to the bottom end of the adjusting post 226. An adjusting handle 228 is fixedly connected to the end of the adjusting post 226 away from the adjusting screw 227.

[0038] During operation, after adjusting the angle of the ball joint 212, the adjustment handle 228 can be rotated to ensure the handrail body 1 is fixed and stable. For example, when the ball joint 212 is adjusted to the correct position, rotating the adjustment handle 228 clockwise will cause the adjustment column 226 to rotate, driving the adjustment screw 227 to move downward within the fixed column 225. This will allow the adjustment screw 227 to be inserted into the top groove 214 or side groove 215 of the inner cavity of the ball joint 212, thereby fixing the current angle of the handrail body 1 and preventing the handrail body 1 from shaking during passenger gripping, thus ensuring passenger safety.

[0039] Furthermore, the mounting assembly 23 includes a mounting cylinder 231, which is fixedly connected to the rear end of the fixed cylinder 221. A polygonal column 232 is fixedly connected to the inner cavity of the mounting cylinder 231, and a connecting rod 233 is fixedly connected to the inner cavity of the mounting cylinder 231.

[0040] During operation, the mounting component 23, as the part connecting to the car roof, provides stable support during the angle adjustment of the armrest body 1. When adjusting the angle of the ball joint 212, the mounting cylinder 231 is tightly connected to the fixed cylinder 221 through the polygonal post 232 and the connecting rod 233, transferring the force on the armrest body 1 to the car roof. For example, when the ball joint 212 is subjected to a large adjustment force, the polygonal post 232 and the connecting rod 233 of the mounting cylinder 231 fit tightly with the polygonal groove 222 and the connecting groove 223 of the fixed cylinder 221, dispersing the force and preventing damage to the connection structure due to excessive local force, thus ensuring the stability of the entire armrest assembly during adjustment and use.

[0041] Furthermore, the mounting cylinder 231 is connected to the fixed cylinder 221 via polygonal columns 232 and connecting rods 233, and several symmetrically arranged polygonal columns 232 and connecting rods 233 correspond one-to-one with the polygonal grooves 222 and connecting grooves 223 in the inner cavity of the fixed cylinder 221.

[0042] During operation, this one-to-one connection method is crucial for adjusting and using the handrail body 1. During adjustment, it precisely limits the relative movement between the fixed cylinder 221 and the mounting cylinder 231, ensuring that the fixed cylinder 221 and the mounting cylinder 231 do not misalign when the ball joint 212 rotates. When passengers grip the handrail, the force on the handrail is evenly distributed. For example, when a passenger forcefully grips the handrail and pulls it to one side, the polygonal column 232 and polygonal groove 222, and the connecting rod 233 and connecting groove 223 cooperate to distribute the pulling force to each connection point, preventing excessive force at a single point from causing loosening and enhancing the reliability of the handrail assembly.

[0043] Furthermore, a fixing groove 224 is also provided in the inner cavity of the mounting cylinder 231. The fixing groove 224 in the inner cavity of the mounting cylinder 231 and the fixing groove 224 in the inner cavity of the fixing cylinder 221 are each semi-circular. A fixing column 225 is fixedly connected to the fixing groove 224 in the inner cavities of the mounting cylinder 231 and the fixing column 221.

[0044] During operation, the two semi-circular fixing grooves 224 and the fixing post 225 further enhance the connection stability between the fixing post 221 and the mounting post 231 during the angle adjustment and use of the handrail body 1. When the ball joint 212 adjusts the angle, the fixing post 225 restricts the relative axial movement of the fixing post 221 and the mounting post 231; when a passenger grips the handrail, even if the handrail is subjected to a large torsional force, the fixing post 225 can prevent relative rotation between the fixing post 221 and the mounting post 231. For example, when the vehicle makes a sharp turn and the passenger twists the handrail to maintain balance, the fixing post 225 can effectively resist the torsional force, ensuring a stable connection between the handrail assembly and the car roof, and protecting passenger safety.

[0045] Furthermore, there are two symmetrically arranged ball joints 212, and the two symmetrically arranged ball joints 212 are fixedly connected to the rear end of the handrail body 1 through the connecting post 211;

[0046] During operation, the two symmetrically arranged ball joints 212 make the handrail body 1 more stable in terms of angle adjustment and force distribution. When adjusting the angle, the handrail body 1 can be adjusted more precisely by operating both ball joints 212 simultaneously. For example, when it is necessary to tilt the handrail body 1 to one side at a certain angle, both ball joints 212 can be fine-tuned simultaneously to allow the handrail body 1 to smoothly reach the desired angle. When a passenger grips the handrail, the two ball joints 212 share the force applied by the passenger, preventing any single ball joint 212 from being damaged due to excessive pressure. For example, when a passenger grips the handrail forcefully, the two ball joints 212 provide support from different directions, extending the service life of the handrail assembly.

[0047] Working principle: The design of the ball joint 212, adjustment groove 213, top groove 214, and side groove 215 in the connecting component 21 provides a foundation for adjusting the angle of the armrest body 1; the fixing component 22 uses structures such as the adjusting screw 227 and adjusting handle 228 to fix the angle of the armrest body 1 after adjustment; the mounting component 23, through the cooperation of the polygonal column 232, connecting round rod 233, fixing groove 224, and fixing column 225, ensures the stable installation of the entire armrest assembly on the car roof and the stability during the angle adjustment process. The coordinated work of multiple components solves the problems of difficulty in adjusting the angle of the armrest and inconvenience in gripping it when passengers adjust their sitting posture, improving the convenience and safety of passengers using the armrest.

[0048] Example 2

[0049] Please see Figures 1-2 As shown, in the comparative embodiment 1 as another implementation of the present invention, it also includes a handrail body 1, which includes a handle 11. The inner cavity of the handle 11 is fixedly provided with a filling layer 12, and the rear end of the handle 11 is fixedly connected to a handrail back plate 13.

[0050] When in operation, as passengers adjust their seating position and grasp the armrest, the padding layer 12 of the handle 11 provides a comfortable gripping experience. For example, passengers may sweat when adjusting their seating position; the padding layer 12 has a certain sweat-absorbing function, and its soft material can conform to the shape of different passengers' hands, reducing hand fatigue. The back plate 13 of the armrest provides stable support for the handle 11. During the passenger's gripping process, especially when the passenger grips forcefully, the back plate 13 prevents the handle 11 from deforming, ensuring that the handle 11 can effectively transmit force to the fixed structure 2, ensuring the reliability of the passenger's grip, and avoiding unstable gripping due to deformation of the handle 11.

[0051] Working principle: The filling layer 12 of the grip 11 is designed from an ergonomic perspective, improving the grip feel and increasing comfort, thus enhancing the convenience of passenger use of the handrail; the back plate 13 of the handrail provides stable support for the grip 11 from a structural mechanics perspective, enhancing the load-bearing capacity of the grip 11. The two work together to further improve the function of the handrail body 1, allowing passengers to grip the handrail more comfortably and safely after adjusting their sitting posture, solving the problem of inconvenience caused by the angle of the handrail, and improving the passenger's riding experience.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
