Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile parts, and particularly relates to a structurally improved automobile center console armrest box hinge with a hovering function. BACKGROUND

[0002] The above-mentioned technical information of the automobile center console armrest box hinge with a hovering function can be found in the published Chinese patent documents, such as CN209723979U (a handrail hinge assembly for connecting upper and lower bodies with a hovering function), CN211765261U (a handrail with a hovering function), CN210134736U (a handrail hinge with a hovering function), CN209454611U (a built-in box center console armrest with a hovering function), and CN208830851U (a hovering automobile armrest box hinge mechanism), etc. The automobile center console armrest box hinges with a hovering function as mentioned above are not limited to the foregoing examples, and have the following common defects: first, when taking out an object such as a driver's license, a driving license, an insurance policy or other certificates, data and small items from the box cavity of the armrest box, the cover (i.e., the box cover) of the armrest box needs to be lifted upward relative to the box body to about 45°-60° for taking out and placing the object, and of course, it can be lifted to less than 90° as needed, and it is desirable that the cover can be reliably automatically hovered in the above-mentioned 45°-60° or 45° to less than 90° state, but in actual use, the reliability of automatic hovering cannot reach the desired level in the industry when the cover is in the above-mentioned angle range, especially when a slight touch occurs, which will cause an abnormal automatic return or self-closing phenomenon, and in the automatic return state, the impact between the cover and the box body is relatively serious, and with the passage of time, especially with the increase in the frequency of use, the cover and the box body will have different degrees of damage, especially due to the decline of the hinge function, the position of the cover will be displaced when closed, i.e., misalignment between them will occur, and once misalignment occurs, the cover cannot be hovered when opened, that is, the hovering action is lost; second, in the initial stage of opening the cover, for example, after the clasps of the cover and the box body are unlocked, the cover is opened to an angle range (such as 45°) before hovering, and because the free end of the cover lacks a structure to help maintain it in the above-mentioned angle range for hovering, it is not conducive to labor-saving operation.

[0003] The "car center console armrest box hinge with hovering function" recommended by Chinese patent CN113503101A remedies the aforementioned common malpractice, and its specific technical measures are: the hinge shaft left shaft head of the support hinge shaft is composed of a hinge shaft left shaft head milling plane and a hinge shaft left shaft head arc surface, and the cross-sectional shape of the hinge shaft left shaft head is correspondingly composed of a D-shaped cross-section; when the box cover support is flipped up and the included angle between the box cover support and the box body support reaches 45°-60°, the hinge shaft left shaft head arc surface contacts the longitudinal diameter hole wall of the elliptical friction plate hole of the friction plate and generates friction, so that the rear end of the box cover support as a free end hovers in a raised state, that is, it can ideally hover at a position of 45°-60°. However, this patent still has the drawback of failing to achieve both simplicity of structure and reliability of hovering, for example, in order to relatively easily lift the rear end of the box cover support as the hinge upper support (away from one end of the hinge) upward, a box cover opening initial assisting mechanism is additionally installed, and in order to reflect the hovering reliability of the box cover support at a position of 45°-60° and especially at 60°, a friction plate hole is formed on the friction plate of the structure system of the friction plate embedding plate, and the shape of the friction plate hole is ensured to be an elliptical hole with a longitudinal diameter smaller than a transverse diameter, and correspondingly, a hinge shaft left shaft head milling plane and a hinge shaft left shaft head arc surface are formed on the hinge shaft left shaft head of the support hinge shaft and at a position corresponding to the friction plate and the friction plate baffle. Such a complex and troublesome structure can reflect that when the box cover support is flipped up to a degree of 45°-60°, the longitudinal diameter direction hole wall of the friction plate hole contacts the hinge shaft left shaft head arc surface and generates friction, so that the rear end of the box cover support (free end, i.e., away from one end of the hinge) is in a raised state at the desired position of 45°-60°, and basically meets the requirements of taking and placing items such as licenses into the body cavity, but the complexity of the structure not only leads to low processing efficiency and is not conducive to resource saving (large material consumption), but also fails to reflect the desired market competitiveness due to the high cost.

[0004] In view of the above factors, it is of positive significance to explore how to achieve both simplification of the overall structure and good and reliable hovering effect, and the technical solution to be introduced below is generated in this background. SUMMARY

[0023] The left hovering action mechanism 3 of the box cover support comprises a left friction plate 31, a pair of left disc-shaped washers 32, a left hinge shaft 33 and a left hinge shaft locking nut 34. The left friction plate 31 is located between the right side of the front end of the left hinge arm 11 of the box cover support and the left side of the upper front end of the left hinge arm 21 of the box body support. The pair of left disc-shaped washers 32 are matched in a face-to-face manner and located at the left side of the front end of the left hinge arm 11 of the box cover support. The left end of the left hinge shaft 33 passes through the upper front end of the left hinge arm 21 of the box body support, the left friction plate 31, the front end of the left hinge arm 11 of the box cover support and the pair of left disc-shaped washers 32 in sequence from the right side of the upper front end of the left hinge arm 21 of the box body support to the left.

The left hinge shaft locking nut 34 is threadedly matched with the left end of the left hinge shaft 33 at the left side of the pair of left disc-shaped washers 32. The right hovering action mechanism 4 of the box cover support comprises a right friction plate 41, a pair of right disc-shaped washers 42, a right hinge shaft 43 and a right hinge shaft locking nut 44. The right friction plate 41 is located between the left side of the front end of the right hinge arm 12 of the box cover support and the right side of the upper front end of the right hinge arm 22 of the box body support. The pair of right disc-shaped washers 42 are matched in a face-to-face manner and located at the right side of the front end of the right hinge arm 12 of the box cover support. The right end of the right hinge shaft 43 passes through the upper front end of the right hinge arm 22 of the box body support, the right friction plate 41, the front end of the right hinge arm 12 of the box cover support and the pair of right disc-shaped washers 42 in sequence from the left side of the upper front end of the right hinge arm 22 of the box body support to the right.

[0024] The technical points of the technical solutions provided by the present application are that the left side of the left friction plate 31 towards the front end of the left hinge arm 11 of the box cover support is provided with a left friction plate inclined surface 311, and the right side of the right friction plate 41 towards the front end of the right hinge arm 12 of the box cover support is provided with a right friction plate inclined surface 411.

[0025] From the above description, it can be seen that the present embodiment is for the left side of the left friction plate 31 being provided with a left friction plate inclined surface 311 and the right side of the right friction plate 41 being provided with a right friction plate inclined surface 411. However, the left side of the left friction plate 31 can be provided with a left friction plate inclined surface 311 only or the right side of the right friction plate 41 can be provided with a right friction plate inclined surface 411 only. Therefore, the present application can have three different embodiments, and any one of the embodiments should be regarded as the technical content disclosed by the present application.

[0026] A left hinge ear 111 is formed at the front end of the left hinge arm 11 of the box cover support, and a left friction plate arc-shaped clearance groove 1111a is formed on the right side surface of the left hinge ear 111. A right hinge ear 121 is formed at the front end of the right hinge arm 12 of the box cover support, and a right friction plate arc-shaped clearance groove 1211a is formed on the left side surface of the right hinge ear 121. The right friction plate arc-shaped clearance groove 1211a is located opposite to the left friction plate arc-shaped clearance groove 1111a and has the same shape as the left friction plate arc-shaped clearance groove 1111a. The left friction plate inclined surface 311 of the left friction plate 31 is engaged with or disengaged from the left friction plate arc-shaped clearance groove 1111a, and the right friction plate inclined surface 411 of the right friction plate 41 is engaged with or disengaged from the right friction plate arc-shaped clearance groove 1211a. During the process of turning the box cover support 1 upward and turning to an angle of 45-60°, the left friction plate arc-shaped clearance groove 1111a gradually engages with the wall thickness area of the left friction plate inclined surface 311, so that the friction gradually decreases. During the process of turning the box cover support 1 downward and turning to a horizontal closed state, the left friction plate arc-shaped clearance groove 1111a gradually disengages from the wall thickness area of the left friction plate inclined surface 311, so that the friction increases. At the same time, the right friction plate arc-shaped clearance groove 1211a gradually engages with the wall thickness area of the right friction plate inclined surface 411, so that the friction gradually decreases. During the process of turning the box cover support 1, the right friction plate arc-shaped clearance groove 1211a gradually disengages from the wall thickness area of the right friction plate inclined surface 411, so that the friction increases. Thus, the structure of the left friction plate arc-shaped clearance groove 1111a and the right friction plate arc-shaped clearance groove 1211a is achieved. The above description proves the technical effects mentioned by the applicant in the technical effect column.

[0027] See Figure 2 and in combination with Figure 1 In this embodiment, the inclination angle of the right friction plate inclined surface 411 is the same as that of the left friction plate inclined surface 311.

Thus, the hinge is protected.

[0032] A box cover support weight reduction cavity 13 is provided on the aforementioned box cover support 1 and in the central area of ​​the box cover support 1. A box body support weight reduction cavity 23 is provided in the central position of the top wall and the rear side wall of the aforementioned box body support 2. Figure 1 Also shown are the box cover bracket mounting fixing holes 14 for fixing the box cover bracket 1 to the armrest box located between the driver and co-driver seats on the vehicle, i.e., the box cover of the aforementioned center console armrest box, and the box body bracket mounting fixing holes 24 opened (preset) on the box body bracket 2 for fixing to the box body of the center console armrest box.

[0033] Depend on Figure 1 As shown, a left hinged arm strength reinforcement rib 1114 of the box lid bracket is formed on the left side of the aforementioned left hinged arm 11 for increasing the strength of the left hinged arm 11 of the box lid bracket, and a right hinged arm strength reinforcement rib 1214 of the box lid bracket is formed on the right side of the aforementioned right hinged arm 12 for increasing the strength of the right hinged arm 12 of the box lid bracket.

[0034] As a preferred solution, the present invention forms a box body bracket left hinge arm reinforcement rib 213 on the aforementioned box body bracket left hinge arm 21, which is protruding toward the right and is used to increase the strength of the box body bracket left hinge arm 21. The same is true for the box body bracket right hinge arm 22, which will not be repeated.

[0035] In this embodiment, the left friction plate 31 and the right friction plate 41 are made of a non-metallic material, which is a plastic, and the plastic is POM (ie, polyoxymethylene resin).

[0036] According to common sense, the present invention is installed on a box body between the driver and passenger seats in a car during use. For details, please refer to CN113503101B mentioned above. Taking actual use as an example, the box body bracket 2 is fixed to the box body by screws. When the box cover bracket 1, together with the box body lid fixed to its surface, is to be lifted upward from the previous horizontal position (i.e., closed position) to the raised position, the driver or passenger in the passenger seat lifts the free end of the box cover bracket 1, which is away from the box body bracket 2. During this process, due to the presence of the arc-shaped clearance grooves 1111a and 1211a of the left and right friction plates, when the box cover bracket 1 is flipped upward ( Figure 1The left and right friction plate arc-shaped accommodation recesses 1111a, 1211a gradually disengage from the wall thickness regions of the left and right friction plates 31, 41, i.e., the wall thickness regions of the left and right friction plate bevels 311, 411, respectively, to gradually reduce the friction during the upward turning of the box cover support 1 to 45°-60°, and gradually engage the wall thickness regions of the left and right friction plates 31, 41, i.e., the wall thickness regions of the left and right friction plate bevels 311, 411, respectively, to gradually increase the friction during the downward returning of the box cover support 1 to the closed horizontal state. At the same time, the left and right friction plate bevels 311, 411 gradually disengage from the left and right friction plate arc-shaped accommodation recesses 1111a, 1211a, respectively, to gradually reduce the friction during the upward turning of the box cover support 1 to 45°-60°, and gradually engage the left and right friction plate arc-shaped accommodation recesses 1111a, 1211a, respectively, to gradually increase the friction during the downward returning of the box cover support 1 to the closed horizontal state. Therefore, the box cover support 1 can reliably hover at any angle within the range of 45°-60° during the upward turning to 45°-60°, thereby achieving an excellent hovering effect. Embodiment 2

[0037] Please refer to Figure 3 In this embodiment, the left and right friction plate bevels 311, 411 are completely the same as those in Embodiment 1. During the upward turning of the box cover support 1 to 45°-60°, the left friction plate bevel 311 gradually disengages from the wall thickness region of the left friction plate arc-shaped accommodation recess 1111a to gradually reduce the friction, and gradually engages the wall thickness region of the left friction plate arc-shaped accommodation recess 1111a to gradually increase the friction during the downward returning of the box cover support 1 to the closed horizontal state. At the same time, the right friction plate bevel 411 gradually disengages from the wall thickness region of the right friction plate arc-shaped accommodation recess 1211a to gradually reduce the friction, and gradually engages the wall thickness region of the right friction plate arc-shaped accommodation recess 1211a to gradually increase the friction during the downward returning of the box cover support 1 to the closed horizontal state.

[0038] The applicant needs to point out that the inclination angles of the left and right friction plate bevels 1111b, 1211b in Embodiment 2 are the same as each other and are also less than 15°. Specifically, the inclination angle α of the left friction plate bevel 311 in Embodiment 1 is less than 15°, that is, the inclination angles of the left and right friction plate bevels 1111b, 1211b are in a step-by-step corresponding relationship with the inclination angles of the left and right friction plate bevels 311, 411.

[0039] The applicant also needs to explain that the left and right friction plate matching bevels 1111b and 1211b described in the embodiment can be directly formed on the left and right hinge ears 111 and 121 of the box cover support hinge arms, respectively, or metal sheets pre-processed with left and right friction plate matching bevels 1111b and 1211b can be welded to the left and right hinge ears 111 and 121 of the box cover support hinge arms, respectively. Therefore, regardless of the above-mentioned any way to form the left and right friction plate matching bevels 1111b and 1211b, it should be considered as the technical content scope disclosed by the application. The rest is the same as the description of embodiment 1.

[0040] In summary, the technical solution provided by the application makes up for the shortcomings in the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the technical effect column above.
