Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to a hinge for a car center console armrest box. Background Technology

[0002] The aforementioned car center console armrest hinge essentially refers to a car center console armrest hinge with a hovering function. Its core value lies in upgrading the hinge from a simple connector to a component that enhances overall vehicle quality and improves user experience. Numerous Chinese patent documents contain technical information related to car center console armrest hinges, a typical example being CN215595293U's "Car Center Console Armrest Hinge with Hovering Function." This patent solution objectively reflects the effects described in its specification, but it has the following shortcomings: Firstly, because it uses a single long shaft (the patent calls it a "bracket hinge shaft") and employs a cover hovering mechanism corresponding to the left hinge arm of the cover bracket, while using a cover opening initial assist mechanism corresponding to the right hinge arm of the cover bracket, therefore… However, single-sided hovering inevitably leads to lid tilting and wobbling; secondly, if the single-sided lid hovering mechanism fails, the basic hovering function is lost; thirdly, since the initial lid opening assist mechanism is located at the right hinge arm of the lid support, and one of the torsion spring legs of the structure system of the initial lid opening assist mechanism (the patent calls it the "second torsion spring leg") must be hooked to the central part of the box support, the torsion spring leg is very long, which affects the performance and reliability of the torsion spring, and there is a risk of interference with other components inside the armrest box, such as wiring harnesses and storage compartments.

[0003] If we adopt the two-sided suspension structure of the "car center armrest box hinge" described in CN216841108U, the balance of damping force or the uniform distribution of force can be improved to a certain extent. However, this patent has the following shortcomings, which are not limited to those mentioned: the structure is not simplified because it uses a bracket hinge bushing with a large diameter and places it outside a bracket hinge shaft; since only one left damping sleeve and one right damping sleeve are used, and the left damping sleeve, i.e., the left damping ring, is limited between the left hinge arm hinge seat and the opposite side of the left hinge arm of the box body bracket, while the right damping sleeve, i.e., the right damping ring, is limited between the right hinge arm hinge seat and the opposite side of the right hinge arm of the box body bracket, once the left and right damping sleeves wear, negative situations such as slippage will occur, and the damping effect will not be achieved.

[0004] As can be seen from the above, there is a positive intention to explore a hinge for the center console armrest box of an automobile that can fully compensate for the shortcomings of the structural design of the aforementioned patent. The technical solution to be introduced below was developed in this context. Summary of the Invention

[0005] The objective of this invention is to provide a car center console armrest hinge that helps to achieve dual-sided hovering, thus avoiding the tilting and swaying that easily occur with single-sided hovering, effectively reducing the wear rate of damping components and increasing overall service life; it also helps to ensure a smooth opening effect without abandoning the initial assist mechanism for opening the cover, thus avoiding interference with the internal components of the armrest box due to neglecting one side; it helps to maintain basic function on the other side even if the hovering performance decreases or even becomes lost due to wear on one side, thus avoiding mutual damage and extending the effective service life; it eliminates the need for a long shaft running from one side of the cover to the other, thus achieving structural simplicity and cost-effectiveness; and it helps to effectively control the damping ring, thus avoiding negative situations such as slippage caused by wear from long-term repeated use.

Secondly, by eliminating the initial lid opening assist mechanism in existing technologies and utilizing the synchronous left and right lid hovering mechanisms on both sides... The design ensures smooth and easy opening, preventing interference with internal components of the armrest box due to compromises in one area. Thirdly, the dual-sided hovering function ensures that if either side experiences reduced or lost hovering performance due to wear, the other side maintains basic functionality, preventing a complete breakdown and extending service life. Fourthly, the absence of a long shaft running from one side of the lid to the other demonstrates structural simplicity and cost-effectiveness. Fifthly, the left and right damping rings of the lid's left and right hovering mechanisms maintain excellent positioning, preventing slippage caused by wear from repeated use and ensuring the reliability and stability of the hovering mechanism.

[0032] Depend on Figure 1 and Figure 3 As shown, a set of lid fixing screw holes 14 are provided at intervals on the aforementioned lid support 1, located at both the front and rear ends. These lid fixing screw holes 14 are used to fix the lid trim panel. Since the lid trim panel is existing technology (see, for example, Chinese Patent CN216841108U), the applicant will not elaborate further. Figures 1 to 3 The diagram also shows housing bracket fixing screw holes 24 on the housing bracket 2. Housing bracket fixing screws (not shown) are used to fix the housing bracket 2 to the housing of the car center console armrest box at positions corresponding to the fixing screw holes 24. This is also described in CN216841108U, and therefore the applicant will not elaborate further. Figures 1 to 3 The diagram also illustrates left and right limiting feet 214 and 224, respectively, located at the upper front end of the left and right hinge arms 21 and 22 of the box support. Each of these left and right limiting feet 214 and 224 is fitted with a left and right limiting foot sleeve, preferably made of rubber or nylon. Since the function of the left and right limiting feet 214 and 224 can be found in CN215595293U and CN216841108U mentioned by the applicant in the background section above, it will not be repeated here.

[0033] Figure 1 and Figure 3 The lid support 1 shown is in the closed state. When the lid support 1 is to be opened upward, since the left and right hinge shafts 3 and 4 form a rotational friction pair with the left and right damping rings 53 and 63 of the left and right lid suspension mechanism 5 and 6 respectively, the left and right damping rings 53 and 63 can exert a damping effect on the left and right hinge shafts 3 and 4 under the combined action of the left and right damping rings 53 and 63, thereby keeping the lid support 1 in the suspended state. As the lid support 1 continues to flip upwards, i.e., continues to open, the left and right hinge shafts 3 and 4 simultaneously drive the left and right torsion springs 55 and 65 to twist in the opposite direction to store energy. At this time, the torsion force generated by the left and right torsion springs 55 and 65 causes the second torsion spring feet 552 and 652 of the left and right torsion springs to act downwards on the grooves 212 and 222 of the second torsion spring feet of the left and right torsion springs. That is to say, a downward force is applied to the left and right hinge arms 21 and 22 of the box body support, keeping the lid support 1 in the upward-flipped state. Since closing the lid support 1 is the opposite of the above, and can be understood by analogy, the applicant will not elaborate further.

[0034] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
