Description

Technical Field

[0001] The present disclosure generally relates to the technical field of automotive interior parts, and more particularly to an adjustment mechanism for adjusting the torque of a torsion spring, a torsion spring assembly including the adjustment mechanism, a storage device including at least one torsion spring assembly, and a vehicle including at least one storage device. Background Art

[0002] Some interior parts or storage devices in a vehicle (e.g., a glove box, a ticket box, a cup holder, or other types of interior parts or storage devices installed in the vehicle) need to be opened with the help of a torsion spring. In some cases, the torque of the torsion spring needs to be adjusted so that the torsion spring can open the interior part or storage device in a predetermined manner (e.g., a predetermined torque, a predetermined speed, a predetermined opening time, etc.).

[0003] In particular, the armrest box of some vehicles includes two armrest parts facing each other, and the two armrest parts are opened by means of their respective torsion springs. It is expected that the two armrest parts can be opened synchronously (i.e., in the same time) by their respective torsion springs. However, many factors may affect the opening synchronicity of the two armrest parts, including: the manufacturing tolerances of the torsion spring for the first armrest part and the torsion spring for the second armrest part in terms of their size and / or torque; the manufacturing tolerances of the damping element for the first armrest part and the damping element for the second armrest part in terms of their size and / or torque; the manufacturing tolerances of the two armrest parts and their accessories in terms of size, weight, and / or coaxiality of the rotating shaft; or other factors. Therefore, in order to achieve the opening synchronicity of the two armrest parts, it may be necessary to adjust the torque of the torsion spring of at least one of the two armrest parts.

[0004] There are various adjustment mechanisms for adjusting the torque of torsion springs in the prior art. However, these adjustment mechanisms have some defects to a greater or lesser extent. For example, some adjustment mechanisms have complex structures, may require a large installation space, or have poor adjustment accuracy; some adjustment mechanisms include adjustment disks fixed by fastening elements (such as screws, etc.), and these adjustment mechanisms need to first remove the fastening elements to release the adjustment disk when adjusting, and need to reuse the fastening elements to fix the adjustment disk after the adjustment is completed. Therefore, these adjustment mechanisms have many adjustment steps and are time-consuming, and cannot achieve real-time direct adjustment; some adjustment mechanisms are also encapsulated in, for example, an armrest box, and when adjusting, the corresponding packaging in the armrest box needs to be first removed, which further increases the difficulty and time spent on adjustment.

[0005] Therefore, there is a need to improve the existing adjustment mechanism for adjusting the torque of the torsion spring.

[0006] It should be noted that the subject matter claimed herein is not limited to the areas described above, is not limited to only solving any disadvantages mentioned above, and is not limited to embodiments used or operated only in environments such as those described above. Rather, this background is provided only to illustrate an exemplary technical field in which some embodiments described herein can be practiced. Summary of the invention

[0070] The present disclosure will be described below with reference to the accompanying drawings, wherein the accompanying drawings illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in a variety of different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present disclosure more complete and fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0071] It should be understood that the terms used in the specification are only used to describe specific embodiments and are not intended to limit the present disclosure. All terms (including technical terms and scientific terms) used in the specification have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of simplicity and / or clarity, well-known functions or structures may not be described in detail.

[0072] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprise" and "contain" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items.

[0073] In the specification, when an element is referred to as being “on,” “attached to,” “connected to,” “coupled to,” or “contacting” another element, etc., the element may be directly on, attached to, connected to, coupled to, or contacting another element, or intervening elements may be present.

[0074] In the specification, the terms "first", "second", "third", etc. are only used for convenience of description and are not intended to be limiting. Any technical features represented by "first", "second", "third", etc. are interchangeable.

[0075] In the specification, spatial relational terms such as "upper", "lower", "front", "back", "top", "bottom", etc. may describe the relationship of one feature to another feature in the drawings. It should be understood that the spatial relational terms include different orientations of the device in use or operation in addition to the orientation shown in the drawings. For example, when the device in the drawings is turned over, features previously described as being "below" other features may now be described as being "above" the other features. The device may also be oriented in other ways (rotated 90 degrees or in other orientations), and the relative spatial relationships will be interpreted accordingly.

[0076] In the specification, the term "proximal side" is used to refer to the side of the adjustment mechanism and its components closer to the operator when the adjustment mechanism according to the present disclosure faces the operator, and the term "distal side" is used to refer to the side opposite to the "proximal side" (i.e., the side farther away from the operator).

[0077] Reference Figure 1 , shows a vehicle 1 according to an embodiment of the present disclosure. The vehicle 1 is provided with one or more interior parts or storage devices, such as, Figure 1 The armrest box 2 shown next to the front seat of the vehicle, or other storage devices (ticket box, cup holder, drawer-type glove box, etc.).

[0078] like Figure 2a and Figure 2b As shown, in some embodiments, the armrest box 2 may include a container 20 for storing objects. The container 20 has an opening for easy access to objects. The container 20 may be substantially rectangular. The armrest box 2 may include a first armrest component 21 and a second armrest component 22 that are disposed above the opening of the container 20 and are opposite to each other on the left and right. In addition to other functions (e.g., for placing and supporting the arms of the driver and passengers, etc.), the first armrest component 21 and the second armrest component 22 are also used together to cover the opening of the container 20. Therefore, the first armrest component 21 and the second armrest component 22 may also be referred to as a "first cover" and a "second cover", respectively.

[0079] The first armrest member 21 and the second armrest member 22 can be in a closed position (such as Figure 2a ) and an open position in which the opening of the container 20 is opened (as shown Figure 2b In some embodiments, the first armrest component 21 and the second armrest component 22 can pivot around the first pivot and the second pivot provided on the left and right sides of the armrest box 2 respectively and pivot between the closed position and the open position.

[0080] The armrest box 2 may include a locking mechanism 23. The locking mechanism 23 may lock the first armrest component 21 and the second armrest component 22 relative to the container 20 in the closed position, thereby locking the first armrest component 21 and the second armrest component 22 in the closed position. The locking mechanism 23 may be unlocked. When the locking mechanism is unlocked, the first armrest component 21 and the second armrest component 22 may be moved from the closed position to the open position. The locking mechanism 23 may be any suitable locking mechanism and will not be described in detail herein.

[0081] The movement of the first armrest component 21 and the second armrest component 22 from the closed position to the open position can be achieved by two torsion springs 24. The two torsion springs 24 can be respectively mounted on two pillars 28 located at different positions, and are used to respectively drive the first armrest component 21 and the second armrest component 22 to pivot around their respective pivots and move to the open position. When installed on the armrest box 2, the two torsion springs 24 are preset with a predetermined torque. Each torsion spring 24 may include a first leg 241 and a second leg 242. After the torque of the torsion spring 24 is set, the first leg 241 of the torsion spring can be set to be fixed, and the second leg 242 of the torsion spring can press the first armrest component 21 or the second armrest component 22 to drive the first armrest component 21 or the second armrest component 22 to pivot.

[0082] As mentioned above, for the armrest box 2 including two armrest components, it is expected that the two armrest components can be opened synchronously by their respective torsion springs. However, due to the influence of the many factors mentioned above, when the two torsion springs 24 with a preset torque are installed on the armrest box 2, it is possible to open the two armrest components asynchronously. Therefore, it may be necessary to adjust the torque of at least one of the two torsion springs 24 to achieve the opening synchronization of the two armrest components.

[0083] The torque of each torsion spring 24 can be achieved by the adjustment mechanism according to the present disclosure. Each torsion spring and its corresponding adjustment mechanism can constitute a torsion spring assembly according to the present disclosure, such as Figure 3 The torsion spring assembly can be installed at the end of the armrest box 2, as shown in FIG. Figure 2a and Figure 2b As shown, the adjustment can be conveniently performed without disassembling the armrest box 2 .

[0084] Reference Figures 4 to 14 , first, the adjustment mechanism 30 according to one embodiment of the present disclosure is described.

[0085] The adjustment mechanism 30 may include a shaft element 31 , an adjustment disk 32 , and an elastic thrust element 33 .

[0086] like Figure 4 , Figure 6a and Figure 6b As more clearly shown, the shaft element 31 may include a shaft portion 311 and a flange portion 312 extending radially outward from a proximal end of the shaft portion 311. The flange portion 312 may include a proximal flange surface 313 and a distal flange surface 314 that are opposite to each other.

[0087] In use (e.g. Figure 5a to Figure 5f As shown, when mounted on the armrest box 2), the shaft element 31 can be set to be stationary. In some embodiments, the shaft element 31 can be fixed to the supporting element of the armrest box 2 using a fastening element 34. To this end, as shown in FIG. Figure 6b As shown more clearly, the shaft portion 311 of the shaft element 31 can be configured as a cylinder. The support element of the armrest box 2 can include a fixing column 25, and the shaft portion 311 of the shaft element 31 can be sleeved on the fixing column 25 (such as Figure 5e and Figure 7b The fastening element 34 can engage the fixing post 25 from the proximal end of the shaft element 31 (ie, from the proximal side of the flange portion 312 of the shaft element 31), thereby fixing the shaft element 31 on the fixing post 25 (as shown in FIG. Figure 5e As shown). The fastening element can be configured as a screw. However, the present disclosure is not limited thereto. The fastening element can also be a pin, a snap element, a rivet, or other types of fastening elements.

[0088] In some embodiments, Figure 6b , Figure 7a and Figure 7b As shown, when the fastening element is configured as a screw, in order to prevent the shaft element 31 from rotating, the outer surface of the fixing column 25 may include at least one rib 251 ( Figure 7b Accordingly, the cylindrical shaft portion 311 of the shaft element 31 may include at least one slot 316 ( Figure 6b and Figure 7b 316). The ribs 251 and the slots 316 cooperate to prevent the shaft element 31 from rotating. However, the present disclosure is not limited thereto. In other embodiments, the inner surface of the cylindrical shaft portion 311 of the shaft element 31 may include at least one protrusion extending radially inward (e.g., a protruding column, a protruding hemispherical portion, a protruding rib, etc.), and the outer surface of the fixing column 25 may include at least one recess (e.g., a groove) for receiving the at least one protrusion, and the shaft element 31 may be prevented from rotating by the cooperation of the protrusion of the shaft element 31 and the recess of the fixing column 25.

[0089] In other embodiments, the shaft element 31 may also have different fixing methods. For example, the distal portion of the shaft portion 311 of the shaft element 31 may be provided with a threaded section, and the shaft element 31 may be directly screwed into the supporting element of the armrest box 2 by using the threaded section. In this embodiment, the fastening element 34 may not be required to fasten the shaft element 31.

[0090] like Figure 4 , Figures 8a to 8d As more clearly shown, the adjustment disk 32 may include a proximal disk surface 321 and a distal disk surface 322 that are opposite to each other, and a lap joint surface 324 located between the proximal disk surface 321 and the distal disk surface 322. The first leg 241 of the torsion spring 24 may lap the lap joint surface 324 (see Figure 9b and Fig.10b The overlapping surface 324 may include a plurality of overlapping portions ( Figure 8d 6 overlapping portions 324-1 to 324-6 are shown in the figure). The radial distance from each overlapping portion of the plurality of overlapping portions to the center O of the adjustment disk 32 is different from the radial distance from the other overlapping portions of the plurality of overlapping portions to the center O of the adjustment disk 32, so that when the first leg 241 of the torsion spring 24 overlaps on different overlapping portions of the overlapping surface 324, the angle of the first leg 241 of the torsion spring 24 relative to the second leg 242 is different (see Fig.12 ), thereby adjusting the torque of the torsion spring 24.

[0091] The adjustment disk 32 may include a central hole 325. When in use, the adjustment disk 32 may be coaxially mounted on the shaft portion 311 of the shaft element 31 and may be configured to coaxially rotate around the shaft portion 311 of the shaft element 31. The rotation of the adjustment disk 32 causes the first leg 241 of the torsion spring 24 to overlap with different overlapping portions of the overlapping surface 324 of the adjustment disk 32 (see Figure 9b and Fig.10b ), so that the torsion of the torsion spring 24 is changed or adjusted. Compared with some adjusting disks in the prior art that rotate using the eccentric wheel principle, the setting mode of the adjusting disk 32 according to the present disclosure coaxially rotating around the shaft portion 311 of the shaft element 31 can not only make the adjusting mechanism according to the present disclosure have a smaller volume and thus a smaller footprint, but also make the adjusting mechanism according to the present disclosure have a higher adjustment accuracy (the coaxially arranged adjusting disk 32 and the shaft element 31 are easier to process and assemble, so that the processing error and assembly error are smaller).

[0092] After the adjusting disk 32 is rotated to adjust the torque of the torsion spring 24 to a desired torque, it is desirable to keep the adjusting disk 32 at a position corresponding to the desired torque without further rotation. To this end, the distal flange surface 314 of the flange portion 312 of the shaft element 31 may be provided with a plurality of stopper elements 315 (e.g., Figure 6b and Figure 6c Accordingly, the proximal disk surface 321 of the adjustment disk 32 may be provided with a plurality of matching limiting elements 326 (such as Figure 8a and Figure 8b When the adjusting disk 32 is rotated to adjust the torque of the torsion spring 24 to the desired torque, the plurality of limiting elements 315 can be engaged with the plurality of matching limiting elements 326 (as shown in FIG. Figure 5d and Figure 5f ), to prevent the adjusting disk 32 from further rotating around the shaft portion 312 of the shaft element 31, thereby maintaining the adjusting disk 32 at a position corresponding to the desired torque. When further adjustment is required, the engagement of the plurality of limiting elements 315 with the plurality of matching limiting elements 326 can be disengaged under the action of external force to allow the adjusting disk 32 to be further rotated.

[0093] In an embodiment according to the present disclosure, the engagement of the plurality of stop elements 315 with the plurality of matching stop elements 326 can be automatically achieved by the elastic thrust element 33. The elastic thrust element 33 is configured to apply an axial thrust toward the proximal side from the distal side of the adjusting disk 32 to the adjusting disk 32 so as to abut the adjusting disk 32 against the flange portion 312 of the shaft element 31, more specifically, against the distal flange surface 314 of the flange portion 312 of the shaft element 31. In this way, when the adjusting disk 32 of the adjusting mechanism adjusts the torque of the torsion spring 24 to the desired torque, the multiple limiting elements 315 and the multiple matching limiting elements 326 can engage under the axial thrust of the elastic thrust element 33 to prevent the adjusting disk 32 from further rotating around the shaft portion 311 of the shaft element 31, and the multiple limiting elements 315 and the multiple matching limiting elements 326 can resist the axial thrust of the elastic thrust element 33 under the action of external force and disengage to allow the adjusting disk 32 to rotate around the shaft portion 311 of the shaft element 31 to implement the next adjustment.

[0094] exist Figures 4 to 14 In the illustrated embodiment, the elastic thrust element 33 is configured as an axially retractable helical spring. However, the present disclosure is not limited thereto. The elastic thrust element 33 may also have a different configuration, for example, it may be configured as an axially retractable spring.

[0095] In the embodiment according to the present disclosure, the number and position of the plurality of limiting elements 315 and the plurality of matching limiting elements 326 may correspond to the number and position of the plurality of overlapping portions of the overlapping surface 324, thereby dividing the adjustment disk 32 of the adjustment mechanism 30 into a plurality of adjustment gears (in Figures 4 to 12 In the illustrated embodiment, the adjustment disk 32 has 6 adjustment gears; of course, the adjustment disk 32 may also have other numbers of adjustment gears, such as 4, 5, 8 or more). With the aid of the elastic thrust element 33, each time the adjustment disk 32 rotates to an adjustment gear, the plurality of limiting elements 315 automatically engage with and limit the plurality of matching limiting elements 326, thereby simplifying the operation (for example, it is not necessary to implement the limiting by screwing on the screws to fix the adjustment disk as in the prior art). In addition, when the adjustment disk 32 needs to be further rotated to the next gear, or when the adjustment disk 32 needs to be rotated again after a period of time to implement the adjustment, an external force can be directly applied to the adjustment disk 32 to disengage the plurality of limiting elements 315 from the plurality of matching limiting elements 326, so that the adjustment disk 32 can be rotated (it is not necessary to first screw down the screws to release the adjustment disk and then rotate the adjustment disk as in the prior art). It can be seen that compared with the prior art, the adjustment mechanism disclosed in the present invention achieves easier adjustment.

[0096] exist Figures 4 to 14 In the illustrated embodiment, the plurality of stop elements 315 of the shaft element 31 are configured as protrusions, and the plurality of matching stop elements 326 of the adjustment disk 32 are configured as a plurality of recesses capable of receiving the protrusions. However, the present disclosure is not limited thereto, and the plurality of matching stop elements 326 of the adjustment disk 32 may also be configured as protrusions, and the plurality of stop elements 315 of the shaft element 31 may be configured as a plurality of recesses capable of receiving the protrusions.

[0097] exist Figures 4 to 14 In the illustrated embodiment, the protrusion may include a first inclined portion 3151 having a smaller inclination angle and a second inclined portion 3152 having a larger inclination angle, so that the protrusion presents an asymmetric structure (see Figure 5f The recessed portion may have a shape that substantially matches the protruding portion (see Figure 5f Such a protrusion can make it possible for the protrusion to slide out of the recessed portion along the first inclined portion 3151 (eg, when the adjusting disk 32 is rotated in a first rotation direction (eg, clockwise)). Fig.11a When the adjusting disk 32 is rotated in a second rotation direction opposite to the first rotation direction (eg, counterclockwise), the protrusion cannot slide out of the recessed portion due to the obstruction of the second inclined portion 3152.

[0098] This asymmetric structure of the protrusion is advantageous. Figure 5a and Figure 5c As shown, in some cases, when the first leg 241 of the torsion spring 24 is obliquely overlapped on the overlap surface 324, the first leg 241 of the torsion spring 24 may apply a torque to the adjustment disk 32 that tends to rotate in one rotation direction (for example, counterclockwise). The second inclined portion 3152 with a larger inclination angle can prevent the adjustment disk 32 from accidentally rotating back to its previous position along the rotation direction.

[0099] In addition, due to the presence of the first inclined portion 3151 with a smaller inclination angle, when it is necessary to disengage the protrusion and the recessed portion and rotate the adjusting disk 32, an external force or torque that rotates the adjusting disk 32 can be directly applied to the adjusting disk 32, and the component of the external force or torque can cause the protrusion to slide out of the recessed portion along the first inclined portion 3151 and disengage from the recessed portion. If the first inclined portion 3151 does not exist, then before rotating the adjusting disk 32, it is necessary to first apply a first external force perpendicular to the proximal disk surface of the adjusting disk 32 to push the adjusting disk 32 distally so that the protrusion slides out of the recessed portion, and then apply a second external force or torque that rotates the adjusting disk 32. However, such an operation is not only complicated, but also difficult to implement in some cases. Therefore, providing a first inclined portion 3151 with a smaller inclination angle is particularly advantageous when the adjustment space is small. For example, Fig.13 and Fig.14 As shown, in some cases, when the adjustment mechanism 30 according to the present disclosure is installed in the armrest box 2, the adjustment disk 32 of the adjustment mechanism 30 may be exposed only in a very small side opening 26 of the armrest box 2. The side opening 26 only allows a force for rotating the adjustment disk 32 to be applied to the adjustment disk 32 from the side by a finger or a tool 27, and therefore, the presence of the first inclined portion 3151 with a small inclination angle makes it possible to rotate the adjustment disk 32 directly through the side opening 26 without disassembling the armrest box 2.

[0100] In some embodiments, Figure 8a and Figure 8b As more clearly shown, the proximal side of the adjustment disk 32 may include a plurality of lugs 327 spaced apart from each other and extending radially outward. The lugs 327 may be pressed or pushed with a finger or a tool to rotate the adjustment disk 32 (e.g., Fig.13 and Fig.14 ), which further facilitates the rotation operation of the adjustment disk 32. In some embodiments, a mark 328 for indicating the torque size of the torsion spring 24 may be provided on the proximal surface of each lug 327. The mark 328 can intuitively show the operator which gear the torque of the torsion spring 24 is in.

[0101] Figures 9a to 11bFIG. 2 shows a process of adjusting the torque of the torsion spring 24 using the adjustment mechanism 30 according to the present disclosure. Figure 9a and Figure 9b In the embodiment, the torsion spring 24 is in the first state (or the first gear position of the adjustment disk 32) and the first leg 241 of the torsion spring 24 overlaps one of the overlapping portions of the overlapping surface 324 of the adjustment disk 32. An external force or torque for rotating the adjustment disk 32 is applied to the adjustment disk 32 with a finger or a tool to rotate the adjustment disk 32. During the rotation of the adjustment disk 32, as shown in FIG. Fig.11a As shown, the external force or torque generates a thrust toward the distal side by means of the first inclined portion 3151 of the protrusion of the shaft element 31, and the thrust toward the distal side resists the axial thrust toward the proximal side applied by the elastic thrust element 33, so that the adjustment disk 32 moves axially toward the distal side while rotating, so that the protrusion of the shaft element 31 slides out of the recessed portion of the adjustment disk 32 along the first inclined portion 3151. When the adjustment disk 32 rotates to the second state or its second gear position (such as Fig.10a As shown), the first leg 241 of the torsion spring 24 overlaps another different overlapping portion of the overlapping surface 324 of the adjustment disk 32 (as shown in FIG. Fig.10b As shown), and the protrusion of the shaft element 31 and the recessed portion of the adjustment disk 32 are re-engaged under the action of the elastic thrust element 33 (as shown Fig.11b When the adjustment disk 32 is rotated from the first state to the second state, as shown in Fig.12 As shown, the position of the first leg 241 of the torsion spring 24 in the first state is different from the position in the second state, thereby producing a change in an angle d. The changed angle d causes a change in the torque of the torsion spring 24. The adjusting disk 32 can be continuously rotated to other states or other gears until the torsion spring 24 is adjusted to a desired torque.

[0102] Figures 15a to 18c 3 shows other embodiments of the limiting element 315 of the shaft element 31 and the matching limiting element 326 of the adjusting disk 32 according to the present disclosure. In these embodiments, the limiting element 315 is still selected from one of a protrusion and a recessed portion capable of receiving the protrusion, and the matching limiting element 326 is selected from one of a protrusion and a recessed portion capable of receiving the protrusion. Figures 15a to 15c In the illustrated embodiment, the protrusion is configured to include a first inclined portion and a second inclined portion having substantially the same small inclination angle. The first inclined portion and the second inclined portion are mirror images of each other (ie, arranged symmetrically with each other). The recess has a shape that substantially matches the protrusion. Figures 4 to 14 Similar to the embodiment shown, in this embodiment, only an external force or torque is applied to rotate the adjustment disk 32 to enable the protrusions to slide out of the recesses and disengage from the recesses. Figures 4 to 14 The difference from the embodiment shown is that in this embodiment, the protrusion can slide out of the recess and disengage from the recess, regardless of whether the adjustment disk 32 is rotated clockwise or counterclockwise. In this embodiment, in order to prevent the adjustment disk 32 from rotating unexpectedly, the force required to slide the protrusion out of the recess can be increased by increasing the roughness of the contact surface between the protrusion and the recess.

[0103] exist Figures 16a to 16c In the illustrated embodiment, the protrusion is configured as a hemispherical shape. The recess has a shape that substantially matches the protrusion. Similarly, in this embodiment, only an external force or torque is applied to rotate the adjustment disk 32 to enable the protrusion to slide out of the recess and disengage from the recess; and in this embodiment, whether the adjustment disk 32 is rotated clockwise or counterclockwise, the protrusion can slide out of the recess and disengage from the recess. In this embodiment, in order to prevent the accidental rotation of the adjustment disk 32, the force required to slide the protrusion out of the recess can be increased by increasing the roughness of the contact surface of the protrusion and the recess.

[0104] exist Figures 17a to 17c In the illustrated embodiment, the projection is configured as a tooth shape. The projection of the tooth shape can extend radially along the circumference. The recess has a shape that is substantially matched with the projection. Compared with the projection shape shown before, the projection of the tooth shape is more slender, and therefore, under the same radius, more tooth-shaped projections can be provided. This enables the regulating mechanism to implement more refined regulation. However, in this embodiment, it is difficult to make the projection of the tooth shape slip out of the recess by directly applying an external force or torque that rotates the adjusting disk 32, and therefore, it is necessary to first apply a first external force perpendicular to the proximal disk surface of the adjusting disk 32 to push the adjusting disk 32 toward the far side so that the projection slips out of the recess, and then apply a second external force or torque that rotates the adjusting disk 32.

[0105] exist Figures 18a to 18c In the illustrated embodiment, the protrusion is configured as a column (e.g., a cylinder, a quadrangular prism, a pentagonal prism, etc.). The recess has a shape that is substantially matched with the protrusion. In this embodiment, the recess can be configured to accommodate a cutout of the cylindrical protrusion. Similarly, in this embodiment, directly applying an external force or torque to rotate the adjusting disk 32 makes it difficult for the cylindrical protrusion to slide out of the recess, and therefore, it is necessary to first apply a first external force perpendicular to the proximal disk surface of the adjusting disk 32 to push the adjusting disk 32 toward the distal side so that the protrusion slides out of the recess, and then apply a second external force or torque to rotate the adjusting disk 32.

[0106] Figures 19a to 19dAn adjustment mechanism 40 according to another embodiment of the present disclosure is shown. The adjustment mechanism 40 may include a fixedly arranged shaft element 41 and an adjustment disk 42 that is sleeved on the shaft element 41 and can rotate coaxially around the shaft element 41. Unlike the shaft element 31, the shaft element 41 may include a shaft portion 411 and a flange portion 412 that extends radially outward from the distal end of the shaft portion 411. The flange portion 412 may include a proximal flange portion 413 and a distal flange portion 414 that are opposite to each other. The shaft element 31 may be fixed to a supporting element of a storage device (such as an armrest box 2) via the flange portion 412. In some embodiments, the shaft element 41 may even be integrally formed on the storage device in a manner that the flange portion 412 faces the storage device.

[0107] The adjusting disk 42 can be sleeved on the shaft portion 411 of the shaft element 41 and can coaxially rotate around the shaft portion 411 of the shaft element 41. The adjusting disk 42 can include a proximal disk surface 421 and a distal disk surface 422 that are opposite to each other, and a lap surface 423 located between the proximal disk surface 421 and the distal disk surface 422. The first leg 241 of the torsion spring 24 can overlap on the lap surface 423. Similar to the previous embodiment, the lap surface 423 can include a plurality of lap portions, and the radial distance from each of the plurality of lap portions to the center of the adjusting disk 42 is different from the radial distance from the other lap portions of the plurality of lap portions to the center of the adjusting disk 42, so that when the first leg 241 of the torsion spring 24 overlaps on different lap portions of the lap surface 423, the angle of the first leg 241 relative to the second leg 242 is different, thereby adjusting the torque of the torsion spring 24.

[0108] Unlike the adjustment disk 32, the adjustment disk 42 further includes a sleeve portion 424 extending distally from the distal disk surface 422. The sleeve portion 424 may be provided with a plurality of ribs 425 extending radially outward. Correspondingly, the proximal flange surface 413 of the flange portion 412 of the shaft element 41 is provided with a plurality of grooves 414 for receiving the plurality of ribs 425. When the adjustment mechanism 40 adjusts the torque of the torsion spring 24 to a desired torque, the plurality of ribs 425 are received in the plurality of grooves 414 to prevent the adjustment disk 42 from rotating around the shaft portion 411 of the shaft element 41.

[0109] In this embodiment, the adjustment mechanism 40 further includes a fastening element 43. The fastening element 43 is configured to fasten the adjustment disk 42 to the shaft portion 411 of the shaft element 41 from the proximal side of the adjustment disk 42. In this embodiment, the adjustment mechanism 40 does not include an elastic thrust element. The adjustment mechanism 40 of this embodiment can have a more compact structure and a small occupied volume, and is therefore particularly suitable for devices with a small installation space.

[0111] Fig. 20 A bill box 50 is shown. The bill box 50 includes a container 51 for holding bills, and the container 51 has an opening 52 for taking and placing bills. The bill box 50 also includes a cover 53 for covering the opening 52. The container 51 or the cover 53 is configured to be movable between a closed position in which the opening of the container is covered and an open position in which the opening of the container is opened. The bill box 50 includes at least one torsion spring assembly including an adjustment mechanism 30 or 40 according to the present disclosure, so as to drive the container 51 or the cover 53 to the open position. The bill box 50 may also include a locking mechanism, which is configured to lock the container 51 and the cover 53 relative to each other in the closed position, and the locking mechanism can be unlocked, after which the locking mechanism is unlocked, the torsion spring assembly can drive the container 51 or the cover 53 to the open position.

For example, these cup holders and drawers all include: a container having an opening for taking out and placing objects; at least one cover, the at least one cover is used to cover the opening, wherein the container or the at least one cover is configured to be movable between a closed position in which the opening of the container is covered and an open position in which the opening of the container is opened; and a torsion spring assembly according to the present disclosure, wherein the torsion spring assembly is configured to drive the container or the at least one cover to the open position.
