Description

Technical Field

[0001] This utility model relates to the field of bus seat technology, specifically a bus seat armrest. Background Technology

[0002] As an important component of the modern road transportation system, passenger comfort has become a key indicator for measuring vehicle quality and market competitiveness. Seats, being the most direct interface between passengers and the vehicle, directly determine the riding experience through their design.

[0003] Typically, a bus seat consists of the seat itself and armrests. There are two armrests, located on either side of the seat body, providing comfortable hand support for the user.

[0004] However, keeping the angle of the armrests fixed when catering to people with different needs will greatly reduce the comfort of using the seat.

[0005] Based on this, the present invention designs a passenger car seat armrest to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a limiting rotor is rotatably provided on the connector head, and a limiting block is fixedly provided. The limiting block is provided with multiple limiting angles distributed around the rotation axis. The limiting rotor has a protrusion. When the protrusion selectively abuts against different limiting angles, the handrail tube is limited at different angles. A torsion spring is also provided between the limiting rotor and the connector head.

[0007] By adopting the above technical solution, the multiple limiting angles distributed around the axis on the limiting block, in conjunction with the protrusion of the limiting rotor, provide multiple clear and stable handrail angle positions, which can meet the different resting posture needs of passengers, improve comfort, and occupy little space.

[0008] Preferably, the limiting rotor has V-shaped grooves at both ends, and the V-shaped grooves and the inclined surface of the limiting angle form abutment fit.

[0009] By adopting the above technical solution, the combination of the V-shaped groove and the limiting angle slope forms a slope self-locking effect. When the handrail tube is subjected to downward pressure, the slope structure can effectively decompose the pressure, resulting in a tendency to tighten as the pressure increases, thereby significantly improving the load-bearing capacity and limiting stability of the handrail.

[0010] Preferably, the fixed base is provided with an adjustment mechanism for adjusting the sliding of the seat. The adjustment mechanism includes a rotating shaft, a rotating ring, and a button. The rotating shaft is disposed on the mounting surface of the fixed base. The rotating ring is provided with a connecting groove. The rotating ring is rotatably connected to the rotating shaft through the connecting groove. One end of the button is fixedly connected to the rotating ring, and the other end extends to the outside of the fixed base.

[0011] By adopting the above technical solution, the armrest angle adjustment function and the seat sliding adjustment function are cleverly integrated into the same fixed base, which greatly simplifies the overall structural design of the seat and saves valuable installation space. Users can adjust the armrest angle and slide the seat back and forth by operating in the same area at the base of the armrest. The operation logic is intuitive, convenient and quick.

[0012] Preferably, a guide ring is fixedly provided on the fixed base, and a guide protrusion is correspondingly provided on the side of the rotating ring, the guide protrusion slidingly engaging with the inner sidewall of the guide ring.

[0013] By adopting the above technical solution, the sliding cooperation between the guide protrusion and the guide ring provides precise trajectory guidance for the rotation of the rotating ring, ensuring that it will not wobble or jam during operation, thereby improving the smoothness and operation feel of the adjustment mechanism.

[0014] Preferably, the fixing seat is provided with a insert for guide engagement with the seat frame.

[0015] By adopting the above technical solution, the guide insertion of the insert and the seat frame enables rapid and accurate positioning between the fixed seat and the seat, simplifying the installation process and improving production efficiency.

[0016] Preferably, the bottom of the armrest tube is provided with a groove for easy finger gripping to adjust the angle.

[0017] By adopting the above technical solution, the specially designed groove provides a clear point of force for the fingers, making it easier for users to apply force when lifting the armrest to adjust the angle, and making the operation more comfortable and effortless.

[0018] In summary, this application has the following beneficial technical effects: By innovatively integrating the armrest angle adjustment mechanism and the seat sliding adjustment mechanism into the same fixed seat, the two major functions are unified and space is shared. This design greatly simplifies the overall structural layout of the seat, making the seat armrest suitable for people with different needs, and greatly improving the comfort of bus seats.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] A bus seat armrest includes an armrest tube 1, a connector 2 disposed at the end of the armrest tube 1, and a fixing seat 3 for fixing to the seat. The connector 2 is rotatably sleeved in the fixing seat 3. A limiting rotor 8 is rotatably disposed on the connector 2, and a limiting block 7 is fixedly disposed thereon. The limiting block 7 is provided with a plurality of limiting angles 15 distributed around the center of the rotation axis 10. The limiting rotor 8 has a protrusion. When the protrusion selectively abuts against different limiting angles 15, the armrest tube 1 is limited at different angles. A torsion spring 11 is also provided between the limiting rotor 8 and the connector 2. V-shaped grooves 6 are provided at both ends of the limiting rotor 8.

[0025] In use, the user lifts the armrest tube 1 upwards. The lifting action forces the limiting block 7 to rotate. The inclined surface of the limiting angle 15 on the block begins to press against the inclined surface of the V-shaped groove 6 that is stuck therein. Due to the action of the inclined surface, this pressing force generates a torque, which overcomes the resistance of the torsion spring 11 and forces the limiting rotor 8 to rotate. This rotation causes the V-shaped groove 6 to rotate out of the V-shaped groove of the limiting angle 15, thereby unlocking. At this time, the armrest tube 1 can rotate freely. When the user rotates the armrest tube 1 to a new angle and rotates another limiting angle 15 on the limiting block 7 to the position corresponding to the V-shaped groove 6, under the action of the restoring force of the torsion spring 11, the limiting rotor 8 quickly rotates back, and its V-shaped groove 6 gets stuck in the new limiting angle 15. The armrest tube 1 is then locked again at the new angle.

[0026] The fixed base 3 is provided with an adjustment mechanism for adjusting the sliding of the seat. The adjustment mechanism is located on the side of the fixed base 3. This mechanism is used to control the unlocking of the slide rail of the bus seat, thereby realizing the adjustment of the seat's fore-and-aft position. The adjustment mechanism includes a rotating shaft 10, a rotating ring 9, and a button 4. The rotating shaft 10 is located on the mounting surface of the fixed base 3. The rotating ring 9 is provided with a connecting groove 14. The rotating ring 9 is rotatably connected to the rotating shaft 10 through the connecting groove 14. One end of the button 4 is fixedly connected to the rotating ring 9, and the other end extends to the outside of the fixed base 3.

[0027] When the user needs to adjust the seat position, they can press button 4 with their finger pointing inwards towards the fixed base 3. The movement of button 4 will cause the rotating ring 9, which is fixedly connected to it, to rotate around the axis of the rotating shaft 10. This rotation is transmitted to the locking mechanism of the seat slide rail through the connecting ring, which will release the lock on the slide rail. At this time, the user can push the seat body to make the entire seat slide forward and backward.

[0028] A guide ring 12 is fixedly installed on the fixed base 3, and a guide protrusion 13 is correspondingly provided on the side of the rotating ring 9. The guide protrusion 13 slides with the inner wall of the guide ring 12. When the user presses the button 4 to drive the rotating ring 9 to rotate, the movement of the rotating ring 9 is no longer a simple rotation around the rotating axis 10. Through the sliding cooperation between the guide protrusion 13 and the inner wall of the guide ring 12, a second motion constraint point is provided for the rotation of the rotating ring 9. This ensures that the movement trajectory of the rotating ring 9 is strictly limited to a fixed arc path, preventing the rotating ring 9 from axially moving or radially deviating during operation.

[0029] The fixed base 3 is provided with inserts 5 for guiding and inserting with the seat frame. The guide insertion design of inserts 5 and slots realizes the installation process of positioning first and then fastening, which improves production and assembly efficiency and ensures the uniqueness and accuracy of the installation position. The bottom of the armrest tube 1 is provided with a groove 6 for easy finger gripping to adjust the angle. When passengers need to lift the armrest to adjust its angle, their fingers will naturally feel and place in the groove 6. The shape of the groove 6 provides the fingers with a clear, stable and comfortable support and force point, so that users can grip the armrest more easily and firmly, effectively preventing slippage when applying force.

[0030] The implementation principle of this embodiment is as follows: When in use, the user lifts the armrest tube 1 upwards. The lifting action forces the limiting block 7 to rotate accordingly. The inclined surface of the limiting angle 15 on it begins to press against the inclined surface of the V-shaped groove 6 that is stuck therein. Due to the action of the inclined surface, this pressing force will generate a torque, which overcomes the resistance of the torsion spring 11 and forces the limiting rotor 8 to rotate. This rotation causes the V-shaped groove 6 to rotate out of the V-shaped groove of the limiting angle 15, thereby unlocking. At this time, the armrest tube 1 can rotate freely. When the user rotates the armrest tube 1 to a new angle and rotates another limiting angle 15 on the limiting block 7 to the position corresponding to the V-shaped groove 6, under the action of the restoring force of the torsion spring 11, the limiting rotor 8 quickly rotates back, and its V-shaped groove 6 is stuck into the new limiting angle 15. The armrest tube 1 is then locked again at the new angle.
