Description

Technical Field

[0001] The present invention relates to the field of armrest boxes, and more specifically, to a torsion spring regulator and an armrest box assembly having the torsion spring regulator. Background Art

[0002] In modern automotive interior design, the armrest box, as an important comfort configuration, is widely used in various vehicles.

[0003] The armrest box usually includes a rotatable lid for accessing items.

[0004] To provide a better user experience, the opening and closing speeds of the armrest box lid need to be precisely controlled.

[0005] For this reason, existing armrest box designs usually include a torsion spring to provide appropriate resistance to ensure that the armrest box lid can be opened and closed smoothly.

[0006] However, in existing armrest box designs, the compression amount of the torsion spring is usually fixed and cannot be adjusted according to user needs.

[0007] This results in that in different usage scenarios, the opening and closing speeds of the armrest box lid may not meet the personalized needs of users.

[0008] In addition, for the existing armrest box lid structure, if it is necessary to adjust the torsion spring force, usually the parameters such as the torsion spring material and the wire diameter of the spring wire need to be adjusted to change the torsion spring force.

[0009] At the same time, the upper and lower covers of the existing armrest box are mostly connected by vibration friction welding. The torsion spring is located in the area between the upper and lower covers. If the torsion spring needs to be replaced, it is very likely that the entire armrest box lid needs to be scrapped to achieve the replacement of the torsion spring.

[0010] Therefore, the traditional method has disadvantages such as a long cycle, many adjustment times, and high costs.

[0011] The existing patent CN209634378U - An armrest board assembly, an armrest box body and an armrest box device of an armrest box does not clearly disclose the technical content for solving the above technical problems.

[0051] The following further describes in detail the specific implementation manners of the present invention by describing the optimal embodiments with reference to the accompanying drawings.

[0052] A torsion spring adjuster 5 includes an adjustment base 51, and an adjustment unit is provided on the adjustment base 51; the adjustment unit includes an adjustment mechanism provided on the adjustment base 51 for adjusting the compression amount of the torsion spring 3 in the armrest box; the adjustment mechanism includes an adjustment block 52 provided on the adjustment base 51; the heights of different regions of the adjustment block 52 are the same or different; the torsion spring adjuster 5 disclosed in the present invention can be used for adjusting the torsion spring force of the torsion spring 3, so as to make the opening time of the armrest box cover meet the design requirements, and can greatly save the design verification cycle and design verification cost.

[0053] The adjustment base 51 of the present invention serves as the basic support structure of the entire torsion spring adjuster 5 for fixing and carrying other components.

[0054] The adjustment base 51 provides an installation platform for the adjustment unit to ensure the stability and reliability of the adjustment mechanism.

[0055] The adjustment unit is installed on the adjustment base 51; the adjustment unit is used for adjusting the compression amount of the torsion spring 3 in the armrest box, so as to control the magnitude of the torsion spring force.

[0056] The adjustment unit mainly includes an adjustment mechanism; the adjustment mechanism is provided on the adjustment base 51; by adjusting the compression amount of the torsion spring 3, the magnitude of the torsion spring force is adjusted.

[0057] The adjusting mechanism disclosed in the present invention mainly includes an adjusting block 52 disposed on an adjusting base 51; the adjusting block 52 is mounted on the adjusting base 51; the extending end of the torsion spring 3 is lapped on the adjusting block 52, and subsequently, by controlling the position of the adjusting base 51, the adjusting base 51 can drive the adjusting block 52 to move. Since the heights of different positions of the adjusting block 52 are different, when different height regions of the adjusting block 52 are used in cooperation with the torsion spring 3, the extrusion force on the torsion spring 3 changes, thereby being able to change the compression amount of the torsion spring 3.

[0058] In addition, it should be noted here that the height of the adjusting block 52 in the present invention refers to the height of the adjusting block 52 along the axial direction of the adjusting base 51.

[0059] In the present invention, the heights of different regions of the adjusting block 52 are the same or different; this forms different technical solutions, thereby increasing the scope of application of the present invention.

[0060] Because different regions of the adjusting block 52 in the present invention have differences, during subsequent use, the extending portion of the torsion spring 3 can be lapped on different regions of the adjusting block 52, so that the compression amounts of the torsion spring 3 are inconsistent, and further, the adjustment of the magnitude of the torsion spring force can be realized, and finally, the opening time of the armrest box cover can meet the design requirements.

[0061] In the present invention, there are various implementation schemes for the adjusting block 52. The adjusting block 52 can be an integral block structure or a plurality of block structures, and can be specifically designed and selected according to needs.

[0062] Generally, for the sake of simplifying the structure, in the present invention, the adjusting block 52 includes a plurality of monomeric convex platforms 521; each of the monomeric convex platforms 521 is annularly distributed on the adjusting base 51; the adjusting block 52 includes a plurality of monomeric convex platforms 521, and these convex platforms are the basic units of the adjusting block 52.

[0063] Each monomeric convex platform 521 can be respectively used to contact the torsion spring 3, and the heights of adjacent monomeric convex platforms 521 are different; based on this design, by changing the torsion spring 3 and its connected monomeric convex platform 521, the compression amount of the torsion spring 3 is adjusted based on the height of the corresponding monomeric convex platform 521.

[0064] The adjusting block 52 of the present invention can be designed with a plurality of monomeric convex platforms 521 to achieve multi-stage adjustment.

[0065] The annular distribution design enables the adjusting block 52 to be arranged around the center of the adjusting base 51. Subsequently, by controlling the adjusting base 51, the rotation of the adjusting base 51 can drive each monomeric convex platform 521 to rotate, and further, the contact and cooperation between different monomeric convex platforms 521 and the torsion spring 3 can be changed. Then, based on the heights of different monomeric convex platforms 521, the adjustment of the compression amount of the torsion spring 3 is realized.

[0066] In addition, the adjusting block 52 of the present invention is in an annular part, and there are various ways of annular distribution. For example, adjacent monomer bosses 521 are arranged in contact in sequence. Essentially, the adjusting block 52 is an integral structure, thus forming a spiral adjusting block 52 structure; as in Embodiment 3 below.

[0067] If the adjacent monomer bosses 521 are spaced apart and there is a height difference between the adjacent monomer bosses 521, such a setting can reduce the number of adjusting blocks 52 used; at the same time, it can also realize the adjustment of the torsional spring force of the multi-stage torsional spring 3.

[0068] Regardless of which of the above arrangements is adopted in the present invention, the adjusting block 52 of the present invention is annularly distributed. Essentially, by designing a plurality of monomer bosses 521 with different heights or shapes, the multi-stage adjustment of the torsional spring force of the torsional spring 3 can be realized to meet different torsional spring force requirements.

[0069] Furthermore, in the present invention, there is a height difference between adjacent monomer bosses 521; by designing monomer bosses 521 with different heights, different compression amounts will be generated when each monomer boss contacts the torsional spring 3, thereby realizing the multi-stage adjustment of the torsional spring force.

[0070] The height difference determines the compression amount of the torsional spring 3 corresponding to each gear, and further determines the magnitude of the torsional spring force.

[0071] Monomer bosses 521 with different heights can correspond to different usage scenarios and requirements, and users can select appropriate gears according to actual needs.

[0072] During operation:

[0073] Initial state:

[0074] The torsional spring 3 contacts one of the monomer bosses 521 and is at the initial compression amount. At this time, the torsional spring force is the initial value.

[0075] Adjusting process:

[0076] Rotate the torsional spring adjuster 5: Realize the rotation of the adjusting block 52 to make different monomer bosses 521 contact the torsional spring 3 in sequence.

[0077] Due to the height difference between adjacent monomer bosses 521, each time it switches to the next boss, the compression amount of the torsional spring 3 will change.

[0078] A higher boss will further compress the torsional spring 3 and increase the torsional spring force; a lower boss will partially release the torsional spring 3 and reduce the torsional spring force.

[0079] Gear shifting:

[0080] By rotating the adjusting block 52, the user can gradually switch to different single bosses 521 to achieve step - by - step adjustment of the torsion spring force.

[0081] Final state:

[0082] After adjusting to the target single boss 521, the torsion spring force reaches the required magnitude.

[0083] The adjusting block 52 is fixed in the current position to ensure the stability of the torsion spring force.

[0084] Furthermore, in the present invention, a guiding 56 arc surface is provided on the side of the single boss 521 away from the adjusting base 51; the guiding 56 arc surface mainly serves as a transition, facilitating the transfer of the extension part of the torsion spring 3 from one single boss 521 to another when the adjusting block 52 rotates; at the same time, it should be noted here that the guiding 56 arc surface in the present invention is generally required to be provided when adjacent single bosses 521 are spaced apart.

[0085] Furthermore, in the present invention, an adjusting inclined surface is provided on each single boss 521; the provision of the adjusting inclined surface enables the torsion spring 3 to have a smooth transition when switching from one single boss 521 to another, avoiding impacts or jams caused by sudden height changes.

[0086] Through the design of the adjusting inclined surface, a more delicate adjustment of the torsion spring force can be achieved between two adjacent gears, providing a more flexible adjustment range.

[0087] The design of the adjusting inclined surface can reduce the direct impact between the torsion spring 3 and the single boss 521, thereby reducing wear and extending the service life.

[0088] In the present invention, adjacent single bosses 521 are in contact with each other in sequence or are spaced apart; adjacent single bosses 521 are closely attached together; the adjusting inclined surfaces on each adjacent single boss 521 combine to form a continuous spiral inclined surface 53; the design of the spiral inclined surface 53 makes the adjustment of the torsion spring force more continuous, and the user can achieve stepless adjustment of the torsion spring force by finely adjusting the rotation angle of the adjusting block 52.

[0089] The contact arrangement makes the overall structure of the adjusting block 52 more compact and saves space.

[0090] The design of the spiral inclined surface 53 not only has functional advantages but also enhances the aesthetic design of the product; at the same time, it ensures the stiffness and strength of the torsion spring adjuster 5.

[0091] There is a certain interval between adjacent single bosses 521; the spaced - apart distribution makes the gears between each single boss 521 more distinct, and the user can clearly feel the gear shift.

[0092] When the monomer bosses 521 are sequentially fitted, the adjustment inclined planes on each monomer boss 521 will combine to form a spiral inclined plane 53; when adjacent monomer bosses 521 are sequentially fitted and arranged, the adjustment inclined planes on each adjacent monomer boss 521 form the spiral inclined plane 53 on the adjustment block 52; here, the spiral inclined plane 53 is essentially a spiral platform structure, realizing stepless adjustment of the torsion spring force.

[0093] Adjustment process:

[0094] Initial state: The torsion spring 3 contacts a certain point on the spiral inclined plane 53 and is at the initial compression amount.

[0095] Rotary adjustment: The user rotates the adjustment block 52 to move the torsion spring 3 along the spiral inclined plane 53.

[0096] Change in compression amount: As the torsion spring 3 moves along the spiral inclined plane 53, its compression amount will gradually increase or decrease, thus realizing continuous adjustment of the torsion spring force.

[0097] The user can adjust the torsion spring force to any position as needed, rather than just a few fixed gears.

[0098] Definite gears in spaced distribution

[0099] There is a certain interval between the monomer bosses 521, and each monomer boss 521 corresponds to a definite gear.

[0100] Adjustment process:

[0101] Initial state: The torsion spring 3 contacts one of the monomer bosses 521 and is at the initial compression amount.

[0102] Rotary adjustment: The user rotates the adjustment block 52 to switch the torsion spring 3 from one monomer boss 521 to another monomer boss 521.

[0103] Change in compression amount: Each time it switches to an adjacent monomer boss 521, the compression amount of the torsion spring 3 will change significantly according to the height difference of the monomer boss 521.

[0104] Final state: The user can select a suitable gear as needed to realize multi-stage adjustment of the torsion spring force.

[0105] Compatibility between continuous adjustment and multi-stage adjustment

[0106] Continuous adjustment: The design of the spiral inclined plane 53 makes the adjustment of the torsion spring force smoother and continuous, suitable for scenarios requiring fine adjustment.

[0107] Multi-stage adjustment: The spaced distribution design provides definite gears, suitable for scenarios requiring quick switching to a fixed torsion spring force.

[0108] Users can select different layout methods according to actual needs, or combine two designs on the same adjustment block 52 to achieve a more flexible adjustment function.

[0109] Whether it is the spiral inclined plane 53 or the spaced distribution, the annular layout of the single boss 521 makes the structure of the adjustment block 52 more compact and saves space.

[0110] Furthermore, in the present invention, the adjustment base 51 includes a base body, the base body includes a lower base 512 and an upper base 511, and the horizontal projection area of the lower base 512 is larger than that of the upper base 511; the adjustment mechanism is arranged on the side of the base body; the lower base 512 serves as the basic support part of the entire adjustment base 51 and provides a stable installation platform.

[0111] A larger horizontal projection area means that it has a larger contact area, can better disperse the load, and improves the stability of the overall structure.

[0112] It is usually used to connect with the upper cover body 12 to ensure the firmness of the adjustment base 51.

[0113] The upper base 511 is a raised part on the lower base 512. One function is to facilitate the operator to pull the torsion spring adjuster 5 during subsequent use, so that the torsion spring adjuster 5 is disengaged from the limit of the limit unit, facilitating the subsequent rotation operation of the torsion spring adjuster 5: In addition, the side of the upper base 511 can be connected to the adjustment block 52 to ensure the strength of the installation position of the adjustment block 52.

[0114] The horizontal projection area of the upper base 511 is smaller than that of the lower base 512, which means that it is relatively compact in structure, can save space; and at the same time facilitates the arrangement of the adjustment unit in its circumferential direction.

[0115] In the present invention, the upper base 511 and the lower base 512 are generally designed as an integral structure.

[0116] In addition, in the present invention, the single boss 521 can be connected to the adjustment base 51 by a detachable connection method. For example, the single boss 521 can be connected to the lower base 512 by bolts. Based on such a setting, different heights of single bosses 521 can be installed according to needs during subsequent use; thereby improving the applicable range of the present invention.

[0117] In the present invention, the single boss 521 adopts a detachable connection, so that when the single boss 521 needs to be replaced or repaired, there is no need to disassemble the entire adjustment block 52 or the adjustment base 51, and only the damaged single boss 521 needs to be replaced separately.

[0118] This design greatly reduces the maintenance cost and time and improves the service life of the product.

[0119] Users can select single bosses 521 with different heights or shapes according to different requirements to achieve personalized adjustment functions.

[0120] For example, users can adjust the adjustment range or accuracy of the torsion spring force by themselves according to the actual usage scenarios.

[0121] Convenient for production and assembly:

[0122] The detachable connection method enables the single boss 521 to be produced and inspected separately, improving production efficiency and the convenience of quality control.

[0123] During the assembly process, the position or quantity of the single boss 521 can be flexibly adjusted according to needs, facilitating the realization of different design requirements.

[0124] The single boss 521 is fixed on the adjustment base 51 through a detachable connection method; common connection methods include:

[0125] Threaded connection: The single boss 521 is fixed on the adjustment base 51 through threads, and only needs to loosen the nut or screw during disassembly.

[0126] Plug-and-play connection: Design slots or jacks, insert the single boss 521 into the adjustment base 51, and directly pull it out during disassembly.

[0127] An armrest box assembly includes an armrest box cover mounting bracket 6, an armrest box cover is provided on the armrest box cover mounting bracket; the armrest box cover is connected to the armrest box cover mounting bracket 6 through a rotating mechanism; the rotating mechanism includes a rotating shaft connected to the armrest box cover, and a torsion spring 3 is provided on the rotating shaft; the torsion spring adjuster 5 is provided on the armrest box cover; the torsion spring 3 is lapped on the torsion spring adjuster 5; the armrest box cover mounting bracket 6 serves as the basic support structure of the entire armrest box assembly, providing stability and strength; it is required to have sufficient rigidity to bear the weight of the armrest box and the load during use.

[0128] The armrest box cover is used to cover the inside of the armrest box, providing an aesthetic appearance and protecting the internal components.

[0129] The armrest box cover is connected to the armrest box cover mounting bracket 6 through a rotating mechanism, and can be opened and closed.

[0130] The rotating mechanism connects the armrest box cover and the armrest box cover mounting bracket 6 to realize the rotational movement of the armrest box cover.

[0131] The rotating shaft is connected to the armrest box cover and is the core component of the rotating mechanism.

[0132] The torsion spring 3 is installed on the rotating shaft, providing rotational elastic force to control the opening and closing speeds of the armrest box cover.

[0133] The torsion spring adjuster 5 adjusts the compression amount of the torsion spring 3, thereby changing the elastic force of the torsion spring 3 to meet different usage requirements.

[0134] The torsion spring adjuster 5 is installed on the armrest box cover, and the torsion spring 3 is lapped on the torsion spring adjuster 5. The elastic force of the torsion spring is adjusted through the gear or inclined plane design of the adjuster.

[0135] Working principle:

[0136] Initial state:

[0137] The armrest box cover is in the closed state, and the torsion spring 3 is in a certain initial compression amount.

[0138] The torsion spring adjuster 5 is set at a certain initial gear position to provide a default torsion spring force.

[0139] Adjustment process:

[0140] The user operates the torsion spring adjuster 5 as needed. By rotating the adjustment block 52, the gear is switched to change the contact position between the single convex platform 521 and the torsion spring 3.

[0141] The single convex platform 521 on the adjuster changes the compression amount of the torsion spring 3 through different height or inclined plane designs, thereby adjusting the magnitude of the torsion spring force.

[0142] Opening process:

[0143] The user opens the armrest box cover, and the armrest box cover rotates around the rotating shaft.

[0144] The torsion spring 3 provides a certain amount of assistance to control the opening speed of the armrest box cover, so as to ensure that the opening time of the armrest box cover meets the design requirements.

[0145] Furthermore, in the present invention, the armrest box cover includes a box cover body 1 and an inspection port cover 14 connected to the box cover body 1; the box cover body 1 includes an upper cover body 12 and a lower cover body 11; a storage cavity is provided inside the armrest box cover; an inspection notch 13 is provided on the lower cover; the inspection notch 13 is communicated with the storage cavity; the inspection port cover 14 covers the inspection notch 13; the upper cover body 12 is fixed to the lower cover body 11, and the upper cover body 12 and the lower cover body 11 form the main structure of the armrest box cover. At the same time, the armrest box cover disclosed in the present invention further includes an inspection port cover 14, and the inspection port cover 14 and the box cover body 1 are designed as a detachable structure, generally connected by a buckle.

[0146] In the present invention, the setting of the inspection port cover 14 allows the inspection port cover 14 to be detached later, exposing the inspection notch 13, and further exposing the torsion spring adjuster 5, facilitating the operator to control the rotation of the torsion spring adjuster 5, thereby realizing the adjustment of the torsion spring force of the torsion spring 3.

[0147] The storage cavity is located inside the armrest box cover and is surrounded by the box cover body 1 (the upper cover body 12 and the lower cover body 11).

[0148] It is used for storing items and placing the torsion spring adjuster 5.

[0149] In the present invention, the maintenance notch 13 is provided on the lower cover body 11.

[0150] The maintenance notch 13 provides an opening for inspecting and maintaining the components inside the armrest box, such as the torsion spring adjuster 5, the rotating mechanism, etc.

[0151] The maintenance notch 13 communicates with the storage cavity, enabling users to directly access the internal components from the outside without disassembling the entire armrest box cover.

[0152] The maintenance cover 14 covers the maintenance notch 13.

[0153] During normal use, the maintenance cover 14 closes the maintenance notch 13 to prevent dust and debris from entering the storage cavity and the internal components; when maintenance is required, the maintenance cover 14 can be quickly disassembled to facilitate the operation of users or maintenance personnel.

[0154] The maintenance cover 14 usually adopts connection methods such as snap fasteners, magnetic attraction, or screws, which are convenient for quick disassembly and installation.

[0155] Normal use:

[0156] The armrest box cover is in the closed state, and the maintenance cover 14 covers the maintenance notch 13 to protect the internal components and the storage cavity.

[0157] Users can access items by opening and closing the armrest box cover.

[0158] Adjustment process:

[0159] When it is necessary to adjust the torsion force of the torsion spring 3, the operator removes the maintenance cover 14, and then manually rotates the torsion spring adjuster 5 so that the contact position between the torsion spring adjuster 5 and the extension part of the torsion spring 3 changes until the torsion force of the torsion spring 3 meets the requirements. After the adjustment is completed, the maintenance cover 14 is reinstalled in place and the use is restored.

[0160] Further, in the present invention, the torsion spring adjuster 5 is connected to the upper cover body 12; the torsion spring adjuster 5 is connected to the upper cover body 12 through a limiting unit; the limiting unit includes a cover plate limiting groove 152 or a cover plate limiting protrusion 15 provided on the upper cover body 12 and an adjusting protrusion 551 or an adjusting limiting groove 55 provided on the adjusting base 51 and cooperating with the cover plate limiting groove 152 or the cover plate limiting protrusion 15 on the upper cover body 12; the torsion spring adjuster 5 is connected to the upper cover body 12 of the armrest box cover; installing the torsion spring adjuster 5 on the upper cover body 12 facilitates user operation and also makes the position of the adjuster more stable and fixed.

[0161] The limiting unit is used to ensure the stable installation of the torsion spring adjuster 5 on the upper cover body 12 and limit its position during the adjustment process to prevent excessive rotation or loosening.

[0162] The essence of the limiting unit is the cooperation between the protrusion and the groove, thereby realizing the installation limit between the two components.

[0163] In the present invention, the limiting unit includes a cover plate limiting groove 152 or a cover plate limiting protrusion 15 provided on the upper cover body 12.

[0164] It also includes an adjusting protrusion 551 or an adjusting limiting groove 55 provided on the adjusting base 51.

[0165] Solution 1: In the present invention, the cover plate limiting groove 152 on the upper cover body 12 cooperates with the adjusting protrusion 551 on the adjusting base 51.

[0188] The torsion spring adjuster 5 is designed with 4 individual convex platforms 521 (as Figure 2 shown), and 4-level adjustment of the compression amount (L1, L2, L3, L4) of the torsion spring 3 is achieved through the height difference of the 4 individual convex platforms 521.

[0189] The bottom of the torsion spring adjuster 5 is designed with a "cross"-shaped adjustment limit groove 55. The adjustment limit groove 55 cooperates with the cover limit protrusion 15 of the upper cover body 12 to achieve the limit of the gear positions of the torsion spring adjuster 5. Starting from the initial gear position, when the torsion spring adjuster 5 rotates 90 degrees clockwise each time, the gear position changes by one level. When it rotates 360 degrees, the gear position of the torsion spring adjuster 5 returns to the initial gear position.

[0190] The quick disassembly and assembly of the maintenance access cover 14 is realized by the snap connection between the maintenance access cover 14 and the lower cover body 11. After the maintenance access cover 14 is disassembled, the gear positions of the torsion spring adjuster 5 can be adjusted. After the gear positions of the torsion spring adjuster 5 are adjusted, the adjustment of the magnitude of the torsion spring force is completed by installing the maintenance access cover 14 in place.

[0192] The quick adjustment of the gear positions of the torsion spring adjuster 5 can be used to quickly adjust the magnitude of the torsion spring force, so as to make the opening time of the armrest box cover meet the design requirements, and the design verification cycle and design verification cost can be greatly saved.

[0193] The present invention adopts the quick disassembly of the maintenance access cover 14 and the quick adjustment of the gear positions of the torsion spring adjuster 5 to realize the quick adjustment of the torsion spring force of the armrest box cover.

[0194] The present invention can greatly reduce the design verification cycle and design verification cost.

[0195] The structure of the present invention is different from the traditional armrest box cover structure, and it can adjust the opening time of the armrest box cover without causing the scrapping of parts.

[0196] The present invention avoids the disadvantages of the traditional armrest box structure, such as long adjustment period of the torsion spring force, many adjustment times and high adjustment cost.

[0203] A "cross" adjustment limit groove 55 is designed at the bottom of the torsion spring adjuster 5, and the adjustment limit groove 55 cooperates with the cover plate limit protrusion 15 of the upper cover body 12 to achieve the limit of the gear position of the torsion spring adjuster 5.

[0204] Starting from the initial gear position, when the torsion spring adjuster 5 rotates an angle clockwise each time, the torsion spring force of the torsion spring 3 changes once. When it rotates 360 degrees, the gear position of the torsion spring adjuster 5 returns to the initial gear position.

[0205] The inspection port cover 14 is snap - connected to the lower cover body 11 to achieve the quick disassembly and assembly of the inspection port cover 14. After removing the inspection port cover 14, the gear position of the torsion spring adjuster 5 can be adjusted.
