Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle armrests, and more specifically, relates to a hinge structure, an armrest and a vehicle of a sub-instrument panel armrest. Background Art

[0002] With the progress of technology and the improvement of living standards, automobiles have become an indispensable means of transportation for people. People have higher and higher requirements for the interior decoration, and have higher requirements for the comfort and convenience of the interior. In addition to carrying and installing various decorative parts and electrical switches, etc., storage is the most core function of the sub-instrument panel. The armrest on the sub-instrument panel is mostly used for storage. How to conveniently and quickly take out items from the armrest requires designing an armrest box top cover that can provide a good experience for passengers. Currently, the existing armrest box top covers are roughly divided into three categories: First, a common rear-flipping armrest box top cover, which has neither damping nor power-assisted opening. This kind of armrest box top cover requires the passenger to open it with one hand and keep supporting it after opening, and use the other hand to take things. It has no power assistance when opening and cannot hover, which is extremely inconvenient; Second, an armrest box top cover with damping throughout the process, which requires a large opening force. Because of the damping throughout the process, the passenger needs to use a very large force to open it, which is also very inconvenient; Third, an armrest box top cover with power-assisted opening, but without damping and cannot hover. This kind of armrest box top cover can rely on power assistance to open the armrest, but the passenger needs to keep supporting it with his hand after the armrest box top cover is opened, otherwise it will fall down, so it is also extremely inconvenient to take things. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hinge structure, an armrest and a vehicle of a sub-instrument panel armrest. The armrest box top cover is constrained on the armrest box through a limit connecting piece, the spring connection component provides power assistance for the opening of the armrest box top cover, and the damping connecting piece enables the armrest box top cover to maintain a hovering state, solving the technical problems that the existing armrest box top cover has no power assistance or cannot hover or has neither power assistance nor can hover when opening, making it easier for the passenger to open the armrest box top cover and safer and more convenient to take items in the armrest box.

[0004] The specific solution content is as follows:

[0005] A hinge structure of a sub-instrument panel armrest includes an upper bracket, a lower bracket and a spring-damping connection component. The spring-damping connection component includes a spring connection component and a damping connection component. The left and right sides of the upper bracket and the lower bracket at the docking part are respectively and directionally openable and closable through the hinged spring connection component and damping connection component.

[0006] The upper bracket of the hinge structure of the armrest on the auxiliary instrument panel of the present utility model is wrapped inside the top cover of the armrest box, and the lower bracket is fixed to the skeleton of the auxiliary instrument panel by bolts. The connecting ends on the left and right sides of the upper bracket and the lower bracket are hinged together through a spring connection assembly and a damping connection assembly respectively, so that the upper bracket can rotate and open and close at the upper end of the armrest box of the auxiliary instrument panel. A limiting connection member is arranged on the armrest box, and the limiting connection member can be connected with the upper bracket in a matching and limiting manner. When the top cover of the armrest box is not opened, the limiting connection member restricts the top cover of the armrest box at the upper end of the armrest box. The torsion spring of the spring connection assembly at the hinge of the upper bracket and the lower bracket is compressed when the top cover of the armrest box is limited on the armrest box. When the top cover of the armrest box is opened, the restraint of the limiting connection member is released, the torsion spring bounces upward, and the upper bracket flips upward under the elastic force of the torsion spring. When the elastic force is equal to the sum of the self-gravity of the top cover of the armrest box and the resistance of the damping connection assembly, it will hover at this position. The passenger does not need to support the top cover of the armrest box by hand, which is convenient for taking out the items in the armrest box. If the item to be taken out is large and the opening angle of the top cover of the armrest box needs to be increased, the top cover of the armrest box can be manually opened upward continuously. Because the top cover of the armrest box is affected by the damping gasket of the damping connection assembly, it can hover at any position in the latter section. It is more convenient and convenient for the passenger to take items from the armrest box, and it avoids the problem that the existing top cover of the armrest box suddenly falls and hits the arm due to operation errors.

[0007] Further, the left and right sides of the rear part of the upper bracket are respectively provided with a downward protruding first connecting end of the upper bracket and a second connecting end of the upper bracket. The left and right sides of the upper end of the lower bracket are respectively provided with a first connecting end of the lower bracket and a second connecting end of the lower bracket corresponding to them. The spring connection assembly is hinged at the docking position of the first connecting end of the upper bracket and the first connecting end of the lower bracket, and the damping connection assembly is hinged at the docking position of the second connecting end of the upper bracket and the second connecting end of the lower bracket.

[0008] The left and right sides of the rear part of the upper bracket are respectively provided with a downward protruding first connecting end of the upper bracket and a second connecting end of the upper bracket. The left and right sides of the upper end of the lower bracket are respectively provided with an upward first connecting end of the lower bracket and a second connecting end of the lower bracket. The spring connection assembly is hinged at the docking position of the first connecting end of the upper bracket and the first connecting end of the lower bracket. The spring connection assembly provides an opening assist for the top cover of the armrest box, so that the passenger does not need to open the top cover of the armrest box with great force, which is easy and labor-saving. The damping connection assembly is hinged at the docking position of the second connecting end of the upper bracket and the second connecting end of the lower bracket. The damping connection assembly provides resistance for the top cover of the armrest box, so that the top cover of the armrest box can hover after being opened. The passenger will not cause it to fall and hit the arm that is taking items from the armrest box because they do not support the top cover of the armrest box, which is more convenient and safe.

[0009] Further, the spring connection assembly includes a torsion spring and a first rotating shaft. The first rotating shaft is fixed to the first connection end of the upper bracket, and the first rotating shaft is rotatably sleeved inside the first connection end of the lower bracket. The torsion spring is rotatably sleeved on the first rotating shaft. One end of the torsion spring is fixedly connected to the first connection end of the upper bracket, and the other end of the torsion spring can be in limit contact with the first connection end of the lower bracket.

[0010] The first rotating shaft of the spring connection assembly is fixed to the first connection end of the upper bracket, and the first rotating shaft is rotatably sleeved inside the first connection end of the lower bracket. The coil part of the torsion spring is rotatably sleeved on the first rotating shaft. One end of the torsion spring is fixedly connected to the first connection end of the upper bracket, and the other end of the torsion spring can be in limit contact with the first connection end of the lower bracket in a compressed state. When the top cover of the armrest box is constrained and locked at the upper end of the armrest box, the torsion spring is in a compressed state and stores energy. After the constraint of the top cover of the armrest box is released, an upward elastic force is provided for the upper bracket and the lower bracket. When the rider presses the button, the lock tongue disengages from the lock hole, and the limit connection assembly and the upper bracket are separated. The top cover of the armrest box has no restraint force, and the upward elastic force provided by the torsion spring causes the top cover of the upper armrest box to be driven by the upper bracket and automatically turn up. When the gravity of the top cover of the armrest box and the resistance of the damping connection assembly reach an equilibrium with the elastic force, the top cover of the armrest box will hover at this position. Generally, the opening angle is controlled to be about 30 degrees at this time. If the item taken is relatively large and the top cover of the armrest box needs to be opened at a larger angle, the top cover of the armrest box can be manually flipped continuously. During this process, the end of the torsion spring in limit contact with the lower bracket is separated from the first connection end of the lower bracket, and the upper bracket is no longer affected by the torsion spring. When the opening of the top cover of the armrest box stops, the top cover of the armrest box hovers due to the influence of the damping gasket, and there is no need to worry about the top cover of the armrest box falling down and hitting the arm. It is more convenient and safe for the rider to take items in the armrest box. The utility model is provided with a limit connection member and a spring connection assembly, which solves the technical problem that there is no assistance when opening the top cover of some existing armrest boxes, makes it easier and more convenient for the rider to open the top cover of the armrest box, provides a better riding experience, and at the same time, the limit connection member ensures that the top cover of the armrest box will not automatically open due to bumps during the driving of the vehicle.

[0011] Further, the damping connection assembly includes two damping gaskets and a second rotating shaft. The second rotating shaft is fixed to the second connection end of the upper bracket, and the second rotating shaft is rotatably sleeved inside the second connection end of the lower bracket. One damping gasket is fixedly sleeved on the second rotating shaft, and the other damping gasket is rotatably sleeved on the second rotating shaft and fixed to the second connection end of the lower bracket. The two damping gaskets are in frictional contact with each other.

[0012] The second rotating shaft of the damping connection component is fixed to the second connection end of the upper bracket, and the second rotating shaft is rotatably sleeved inside the second connection end of the lower bracket. The two damping gaskets rub against each other to generate resistance, preventing the upper bracket from falling, so that the upper bracket can hover. One of the two damping gaskets is fixedly sleeved on the second rotating shaft and can rotate with the rotation of the second rotating shaft. The other damping gasket is rotatably sleeved on the second rotating shaft and is fixed to the second connection end of the lower bracket, so that this damping gasket does not rotate with the rotating shaft. During the process of opening the top cover of the armrest box, the two damping gaskets rub against each other to generate resistance, playing a role in preventing the upper bracket from falling and hovering in the air.

[0013] A sub-instrument panel armrest includes an armrest box and a limit connecting member, and further includes the hinge structure of the sub-instrument panel armrest. The lower bracket is fixedly connected to the sub-instrument panel skeleton at the rear end of the armrest box. The front end of the upper bracket is provided with a limit portion. The limit connecting member is arranged on the sub-instrument panel skeleton at the front end of the armrest box and can be limit-connected to the limit portion of the upper bracket.

[0014] The lower bracket of the hinge structure of the sub-instrument panel armrest is fixedly connected to the sub-instrument panel skeleton at the rear end of the armrest box. The bracket is covered inside the top cover of the armrest box. The front end of the upper bracket is provided with a limit portion. The limit connecting member is arranged on the sub-instrument panel skeleton at the front end of the armrest box, and the limit connecting member can be limit-connected to the limit portion of the upper bracket. When the top cover of the armrest box is not opened, the limit connecting member is limit-connected to the limit portion of the upper bracket, restricting the top cover of the armrest box and closing it on the upper opening of the armrest box. When the top cover of the armrest box is opened, the connection between the limit connecting member and the limit portion of the upper bracket is disconnected. The top cover of the armrest box loses its restraint. The spring connection component provides an opening assist for the top cover of the armrest box, and the damping connection component provides resistance, so that the top cover of the armrest box can remain hovering after being opened. The restraint of the limit connecting member prevents the top cover of the armrest box from automatically opening due to bumps during the driving of the vehicle. The structure of the limit connecting member can adopt different structural designs and be selected according to needs.

[0015] Further, the limit connecting member includes a button, a locking tongue, a push plate, a first mounting seat and a second mounting seat. The first mounting seat and the second mounting seat are respectively fixedly connected to the sub-instrument panel skeleton at the front end of the armrest box. The button is slidably sleeved on the front end of the first mounting seat. The rear end of the button is fixedly connected to the upper end of the front face of the push plate. The lower end of the push plate is hinged to the upper end of the front part of the second mounting seat. The rear face of the push plate is provided with a downward extending end. The lower end of the locking tongue is hinged to the lower end of the rear part of the second mounting seat. The front face of the middle part of the locking tongue is provided with a horizontal connecting plate. The lower end of the extending end touches the upper end face of the connecting plate. The upper end of the locking tongue is provided with a clamping portion. The limit portion of the upper bracket is a locking hole, and the clamping portion can be telescopically clamped into the locking hole at the front end of the upper bracket.

[0016] The limit connecting piece can be a folding telescopic locking structure composed of a button, a locking tongue, a push plate, a first mounting seat and a second mounting seat, enabling the locking tongue to telescopically lock into the front lock hole of the upper bracket. When the top cover of the armrest box is not opened, the top cover of the armrest box is constrained and fixed at the upper end of the armrest box by the limit connecting piece. When the top cover of the armrest box needs to be opened, press the button, and the button moves towards the rear end of the first mounting seat. The rear end of the button abuts against the upper end of the front face of the push plate. The push plate is pushed by the rear end of the button to rotate towards the upper bracket. The downward extending end of the push plate rotates downward as the push plate rotates. The extending end presses on the connecting plate of the locking tongue, forcing the connecting plate to move downward accordingly. The lower end of the locking tongue is hinged to the lower rear end face of the second mounting seat. The connecting plate drives the upper end of the locking tongue to rotate towards the push plate. The lower end of the locking part of the locking tongue is clamped together with the lower end of the lock hole. When the whole locking tongue rotates towards the push plate, the clamping part also rotates accordingly. The lower end of the clamping part rotates upward until it is no longer clamped with the lower end of the lock hole, and the whole clamping part disengages from the front face of the lock hole of the upper bracket. The top cover of the armrest box is no longer constrained by the limit connecting piece. The torsion spring of the spring connection assembly provides an upward elastic force to bounce open the top cover of the armrest box, and the two damping gaskets of the damping connection assembly provide resistance to enable the top cover of the armrest box to maintain a hovering state. The first mounting seat and the second mounting seat are respectively mounted on the skeleton of the front auxiliary instrument panel of the armrest box.
