Description

Technical Field

[0001] The present invention relates to an armrest box, and more particularly, to a technology related to an armrest cover opening and closing control structure, that is, the armrest cover can be opened and closed stably and with high reliability, and can be selectively opened from the front and rear. Background Art

[0002] Generally, an armrest box is provided between the driver's seat and the front passenger seat in a vehicle, and an armrest cover of the armrest box is used as an armrest to provide comfort to the passenger. At the same time, since the armrest cover can be opened, items can be stored in the armrest inner box.

[0003] In the past, the armrest box could only be opened from the front, so passengers sitting in the driver's seat and the front passenger seat could easily open the armrest box, but passengers sitting in the rear seats had the inconvenience of being unable to open the armrest box.

[0004] In order to eliminate this inconvenience, an armrest box that opens in both the front and rear directions or an armrest box that opens on both sides of the left and right has been proposed.

[0005] This two-way armrest box has the problem that the armrest cover itself is separated from the armrest box when the opening buttons on both sides are operated simultaneously.

[0006] Furthermore, with the adoption of a complex structure required for bidirectional opening, there is a problem that the number of structural parts increases, and there is a problem that the operational reliability of the armrest box deteriorates and the manufacturing cost increases.

[0007] Furthermore, with the adoption of a hinge structure required for bidirectional opening, there is a problem that when the armrest cover is opened in one direction, the hinge structure in the opposite direction cannot stably support the rotation of the armrest cover.

[0013] Technical issues

[0014] The present invention is intended to solve the problems of the prior art as described above, and provides an armrest box in which an armrest cover can be selectively opened from one side, front or rear.

[0015] In particular, an object of the present invention is to solve the problem that the armrest cover itself is separated from the armrest box when both side opening buttons of the armrest box are operated simultaneously.

[0016] In addition, the present invention aims to solve the following problem: as the complex structure required for two-way opening is adopted, the number of structural parts increases, and the combination of complex structural parts leads to poor operational reliability of the armrest box and increased manufacturing costs.

[0017] Another object of the present invention is to solve the problem that, when the armrest cover is opened in one direction, the hinge structure in the opposite direction cannot stably support the rotation of the armrest cover, as the hinge structure required for bidirectional opening is adopted.

[0018] The purpose of the present invention is not limited to the above-mentioned contents, and other purposes and advantages of the present invention not mentioned can be understood from the following description.

[0019] Technical Solution

[0020] According to an embodiment of the armrest box of the present invention for achieving the above-mentioned purpose, the present invention may include: a rod component, which moves along the length direction according to the operation of the operation button unit for operating the opening of the armrest cover, and is provided with a guide hole with a preset length along the oblique direction relative to the above-mentioned length direction; a locking control unit, which is provided with a locking adjustment protrusion inserted and fastened in the above-mentioned guide hole, and is guided by the above-mentioned guide hole and moves along the horizontal direction to insert or lead out a terminal part of the locking rod into the locking hole of the armrest body or lead out from the locking hole of the armrest body, thereby adjusting the locking and releasing of the above-mentioned armrest cover; and a base plate for installing and supporting the above-mentioned rod component and the above-mentioned locking control unit.

[0021] As an example, the rod component may include: a center rod, which moves along the length direction according to the operation of the operation button unit; and a wing portion, which extends toward the outer side of the side of the center rod and is provided with the guide hole. The locking control unit may include: a locking adjustment component, which is provided with the locking adjustment protrusion on one side, and moves along the horizontal direction according to the guidance of the locking adjustment protrusion by the guide hole; and a locking rod, which is fastened to the other side of the locking adjustment component, and is moved by the locking adjustment component to insert a portion of the end into the locking hole of the armrest body or lead a portion of the end out of the locking hole of the armrest body.

[0022] As an example, the wing portion may be provided with a left wing portion and a right wing portion on the left and right sides of the side of the center rod, and the locking control unit may include a left locking control unit corresponding to the left wing portion and a right locking control unit corresponding to the right wing portion.

[0023] As an example, the above-mentioned locking control unit may also include a support plate, which is fixedly fastened to the above-mentioned base plate, providing a moving space for the above-mentioned center rod along the length direction, supporting the above-mentioned locking adjustment component and supporting the horizontal movement of the above-mentioned locking adjustment component. The above-mentioned operation button unit may include: an operation button body; an operation button support cover, which is fixedly installed on the above-mentioned support plate, supporting the above-mentioned operation button body and supporting the length direction movement; an operation button return spring, one side of which is fastened to the above-mentioned operation button body, and the other side is fastened to the above-mentioned operation button support cover, for returning the above-mentioned operation button body to its original position.

[0024] As an example, the rod component may also include a center rod return mechanism, one side of which is fastened to the center rod and the other side is fastened to the base plate. The mechanism is endowed with elastic force based on the pressure generated by the movement of the center rod, and the center rod is returned to its original position by the restoring force generated by the elastic force.

[0025] As an example, the amount of operation work required by the operation button unit to open the armrest cover may be adjusted by adjusting the inclination angle of the guide hole in the oblique direction with reference to the longitudinal direction.

[0026] As an example, the guide hole may be formed by an arc protruding upward in the diagonal direction or an arc protruding downward in the diagonal direction, and is used to adjust the amount of operating work required by the operating button unit to open the armrest cover.

[0028] Preferably, when the front of the armrest cover is opened, the rear locking rod of the rear locking control unit rotates with a portion of its end inserted into the rear locking hole of the armrest body, thereby serving as a hinge function; and when the rear of the armrest cover is opened, the front locking rod of the front locking control unit rotates with a portion of its end inserted into the front locking hole of the armrest body, thereby serving as a hinge function.

[0029] In addition, the front center rod of the front rod component and the rear center rod of the rear rod component make their respective ends correspond to each other along the length direction. The armrest box may also include an armrest opening direction adjustment unit, which is arranged between the front center rod and the rear center rod. When the armrest cover is opened in one direction, either forward or backward, the opening in the other direction is restricted.

[0030] As an example, the armrest opening direction adjustment unit may include: a guide partition for guiding the length direction movement of the front center rod and the rear center rod; and an opening space capable of moving the end of one selected from the front center rod and the rear center rod, and the length of the opening space may be sufficient to enable the armrest cover to be opened to one side selected from the front or the rear so that the end of one of the front center rod and the rear center rod moves to contact the end of the other side.

[0031] As an example, the present invention may further include a lifting mechanism, which is provided on the armrest body and is pressurized by the armrest cover to be given elastic force when the armrest cover is closed, and which is lifted by the restoring force when the armrest cover is opened.

[0032] Effects of the Invention

[0033] According to the present invention as described above, the opening and closing of the armrest cover can be achieved stably and with high reliability, and the armrest cover can be selectively opened in the front and rear directions.

[0034] In particular, a guide hole in an oblique direction can be provided in a rod part that moves along the length direction according to the operation of an operating button, so that the horizontal movement of the locking rod can be controlled by the guidance of the guide hole, thereby enabling the armrest cover to be opened and closed stably and with high reliability through a simple structure.

[0035] In addition, by adjusting the inclination angle along the diagonal direction of the guide hole for guiding the opening of the armrest cover, or by forming a guide hole with an arc protruding toward the upper or lower side of the diagonal direction, the amount of operating work required by the operating button unit to open the armrest cover can be adjusted, thereby feeling a different operating feel.

[0036] In addition, in the present invention, the armrest opening direction adjustment unit can be used to selectively control the opening direction of the armrest cover in a two-way opening armrest box, thereby solving the problem of the armrest cover itself being separated due to the front and rear of the armrest cover being opened simultaneously.

[0037] The effects of the present invention are not limited to the above-mentioned contents, and other effects not mentioned can be clearly understood by a person skilled in the art to which the present invention belongs from the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0131] In connection with this, see and Figure 7 and Figure 8 An example of realizing the locking function and hinge function of the armrest cover in the armrest box of the present invention is shown in FIG.

[0132] In the above Figure 7 and Figure 8 For the convenience of explanation, the bottom plate 210 is omitted in the drawings.

[0133] The guide plate 540 may be provided with a locking member 550, and the locking member 550 may be installed in a manner of penetrating the guide plate 540. A locking hole 555 corresponding to the locking portion 381 of the locking lever 380 may be provided on one side of the locking member 550.

[0134] The locking rod 380 can be supported by the locking adjustment component fastening portion 363 of the support plate 360 ​​and moved toward the outside in the horizontal direction so that the locking portion 381 of the locking rod 380 is inserted into the locking hole 555 of the locking component 550, thereby limiting the opening by closing the armrest cover 100.

[0135] Conversely, the armrest cover 100 can be opened by moving the locking rod 380 inwardly along the horizontal direction toward the inside of the locking adjustment component fastening portion 363 of the support plate 360 ​​so that the locking portion 381 of the locking rod 380 is drawn out from the locking hole 555 of the locking component 550.

[0136] A rotating ring 541 for fastening the other side of the locking member 550 can be fixedly installed on the guide plate 540. The locking member 550 can be held and supported by the rotating ring 541 and can rotate on the rotating ring 541. In order to make the locking member 550 rotate more easily, a bearing can be provided. The locking member 550 can also be composed of a bearing and a locking hole member by inserting and fastening the locking hole member 555 to the bearing.

[0137] In addition, a lifting mechanism 560 may be provided on the guide plate 540. The lifting mechanism 560 may include a lifting block 561, a lifting spring 565, and the like.

[0138] The lifting mechanism 560 can lift the armrest cover 100 at the initial opening time point of the armrest cover 100 according to the operation of the operation button unit 120 by the passenger, so as to support the passenger to complete the action of opening the armrest cover 100 more easily.

[0139] Fig. 9 as well as Figures 10a to 10d An operation diagram showing an embodiment of a lifting mechanism in an armrest box of the present invention.

[0140] The side partition plate 240 of the bottom plate 210 may be provided with a lifting protrusion 245 , and the lifting mechanism 560 may be provided on the guide plate 540 to correspond to the lifting protrusion 245 of the bottom plate 210 .

[0141] The lifting mechanism 560 may include a lifting block 561 and a lifting spring 565 .

[0142] A lifting block fastening portion 545 for fastening the lifting block 561 may be provided on the guide plate 540, and the lifting block 561 may be installed on the lifting block fastening portion 545 of the guide plate 540 in such a manner that the upper portion is exposed to the inner side of the guide plate 540 and the lower portion is located on the outer side of the guide plate 540.

[0143] An upper portion of the lifting spring 565 may be fastened to a lower portion of the lifting block 561 , and a lower portion of the lifting spring 565 may be supported by the guide plate 540 .

[0144] When the armrest cover 100 is closed, the lifting protrusion 245 provided on the side partition plate 240 of the bottom plate 210 pushes and presses the lifting block 561 of the lifting mechanism 560 downward. As the lifting block 561 is pushed downward, the lifting spring 565 is pressurized and accumulates elastic force. While the armrest cover opening and closing device 200 maintains the armrest cover 100 in the closed state, the lifting spring 565 is maintained in the pressurized state and the accumulated elastic force is maintained. Fig.10a and b show a state where the lifting block 561 is pushed downward by the lifting protrusion 245 and is pressurized.

[0145] According to the operation of the operating button unit 120 by the passenger, at the initial time point of opening the armrest cover 100, the closed state of the armrest cover 100 formed by the armrest cover opening and closing device 200 is released, and the pressing force of the lifting spring 565 is released, thereby generating a restoring force.

[0146] The lifting block 561 is instantly pushed upward and a lifting force is applied due to the restoring force generated by the accumulated elastic force of the lifting spring 565. The lifting force of the lifting block 561 will push the lifting block 561 and the lifting protrusion 245 to be lifted, thereby applying an instantaneous lifting force to the bottom plate 210, so that the armrest cover 100 can be raised to a specified level.

[0147] In this way, the armrest cover 100 is raised to a predetermined level by the lifting mechanism 560 at the initial opening time of the armrest cover 100 , so that the passenger can lift and open the armrest cover 100 more easily.

[0148] Will refer to Fig.11 and Fig.12 The opening and closing operation of the armrest cover by the armrest cover opening and closing device in the present invention will be described.

[0149] Above Fig. 9 An example of a state in which the opened armrest cover is closed by the armrest cover opening and closing device is shown.

[0150] In a normal state where the passenger does not operate the operation button unit 120 , the rod member 310 maintains the initial position and the lock control unit 350 can maintain the closed state so that the armrest cover 100 will not be opened due to impact or shaking.

[0151] More specifically, when the passenger does not operate the operation button unit 120, one side of the center rod return spring 345 of the center rod return mechanism 340 is supported by the center rod return support protrusion 230 and pushes the center rod 320 forward in the length direction by elastic force to maintain the center rod 320 in the initial position.

[0152] As the center rod 320 is maintained at the initial position by the center rod return mechanism 340, the guide hole 335 of the wing 330 can guide the locking adjustment protrusion 371 of the locking adjustment component 370 to the initial position. Among them, the initial position of the locking adjustment protrusion 317 can be the lower end of the guide hole 335 in the oblique direction.

[0153] With the guidance of the guide hole 335 , the lock adjustment protrusion 317 maintains the initial position, and the lock adjustment member 370 moves from the initial position toward the outermost side in the horizontal direction within the movable range and is positioned.

[0154] As the locking adjustment component 370 moves toward the outermost horizontal side and is positioned, the locking rod 380 will also move toward the outermost horizontal side within the movable range, and the locking portion 381 of the locking rod 380 can be inserted into the locking hole 555 provided in the locking component 550 of the guide plate 540 to be fixed and maintained.

[0155] That is, in a normal state where the passenger does not operate the operating button unit 120, the center rod 320 is maintained in its initial position by the center rod return mechanism 340. With the guidance of the guide hole 335 of the wing 330, the locking adjustment protrusion 317 of the locking adjustment component 370 is located at the horizontal outermost side within the movable range from the initial position of the center rod 320, so that the locking rod 380 is located at the horizontal outermost side within the movable range through the locking adjustment component 370, and is inserted into the locking hole 555 provided on the locking component 550 of the guide plate 540 to be fixed and maintained, thereby stably maintaining the closed state of the armrest cover 100.

[0156] Above Figures 10a to 10d An example of a state in which the armrest cover is opened by the armrest cover opening and closing device is shown.

[0157] When the passenger operates the operation button unit 120 , the lever member 310 is pushed to the rear in the length direction and moves to the operation position. The movement of the lever member 310 allows the lock control unit 350 to open the armrest cover 100 .

[0158] More specifically, if the passenger operates the operation button unit 120 , the center rod 320 may be moved to the operation position by being pushed to the rear in the length direction by the operation button unit 120 .

[0159] As the center rod 320 moves toward the operation position in the longitudinal direction, the wing 330 moves together and the locking and adjusting protrusion 317 is pulled to the inside in the horizontal direction to move to the operation position under the guidance of the guide hole 335 of the wing 330. The operation position of the locking and adjusting protrusion 317 can be the upper end of the guide hole 335 in the oblique direction.

[0160] With the guidance of the guide hole 335 , the lock adjustment protrusion 317 will move to the operating position, and with the movement of the lock adjustment protrusion 317 , the lock adjustment component 370 can move toward the innermost side in the horizontal direction within the movable range.

[0161] As the locking adjustment component 370 moves toward the innermost side in the horizontal direction, the locking rod 380 also moves toward the innermost side in the horizontal direction within the movable range, so that the locking portion 381 of the locking rod 380 can be drawn out from the locking hole 555 provided in the locking component 550 of the guide plate 540.

[0162] That is, when the passenger operates the operating button unit 120, the center rod 320 moves from the initial position to the operating position through the operating button unit 120. As the center rod 320 moves, according to the guidance of the guide hole 335 of the wing 330, the locking adjustment protrusion 317 of the locking adjustment component 370 moves toward the innermost horizontal side within the movable range, and the locking rod 380 moves to the innermost horizontal side within the movable range through the locking adjustment component 370 to be led out from the locking hole 555 set in the locking component 550 of the guide plate 540, thereby releasing the closed state of the armrest cover 100 and allowing the armrest cover 100 to be opened.

[0163] Furthermore, if the passenger releases the operation of the operation button unit 120, the center rod 320 moves from the operation position to the initial position through the center rod return mechanism 340. As the center rod 320 moves to the initial position, the locking control unit 350 can return the armrest cover 100 to the closed state. The closed state of the armrest cover 100 achieved by the locking control unit 350 is similar to the closed state achieved by the above-mentioned Fig. 9 The contents of the description are the same, so their detailed description will be omitted.

[0164] In addition, in the present invention, the amount of operation work required by the operation button unit 120 to open the armrest cover 100 can be adjusted, and an embodiment related thereto will be described.

[0165] Figures 13a to 16b Various embodiments of the armrest cover opening and closing device for adjusting the amount of operating work required to open the armrest cover in the armrest box of the present invention are shown. Fig.11 and Fig.12 The embodiments in .

[0166] The lock adjustment protrusion 371 is moved according to the guidance of the guide hole 335 provided in the wing portion 330 of the center rod 310, so that the opening and closing of the armrest cover 100 can be adjusted. In the present invention, the amount of operation work required to open the armrest cover 100 can be adjusted by adjusting the guide hole 335 provided in the wing portion 330. The amount of operation work means the amount of work that the passenger needs to do in the process of operating the operation button unit 120 to open the armrest cover 100.

[0167] As an example, refer to the above Fig.13a and Fig.13b When the locking adjustment protrusion 371 is located at the lower end of the guide hole 335 in the oblique direction, the armrest cover 100 can be kept in a normal state of being closed. Moreover, when the locking adjustment protrusion 371 is located at the upper end of the guide hole 335 in the oblique direction, the armrest cover 100 can be opened in an operation state.

[0168] As the lock regulating protrusion 371 is moved between the lower end and the upper end in the oblique direction of the guide hole 335 , a normal state of closing the armrest cover 100 and an operation state of opening the armrest cover 100 may be switched.

[0169] In the normal state of closing the armrest cover 100, only when the locking rod 380 is inserted into the locking hole 555 of the locking component 550 to above the specified level can a stable closed state be maintained. In order to switch to the operating state of opening the armrest cover 100, the locking rod 380 must be completely pulled out from the locking hole 555 of the locking component 550.

[0170] The movable range of the lock regulating protrusion 371 in the guide hole 335 may correspond to a movable range between a position for maintaining a closed normal state of the lock lever 380 and a position for an open operating state.

[0171] That is, in the oblique direction of the guide hole 335 , the horizontal length VL may be the horizontally movable range of the lock adjustment protrusion 371 , which may correspond to the movable range of the lock lever 380 .

[0172] Furthermore, in the oblique direction of the guide hole 335 , the lengths HL1 and HL2 in the vertical direction are the distances by which the operation button body 130 of the operation button unit 120 moves according to the operation of the passenger, which may correspond to the lengthwise movement distance of the center rod 320 .

[0173] Among the elements related to the oblique direction of the guide hole 335, taking into account the movable distance of the locking rod 380, the horizontal length element is also maintained at VL and the vertical length element among the elements related to the oblique direction of the guide hole 336 is adjusted, so that the amount of operating work required by the operating button unit 120 to open the armrest cover 100 can be adjusted.

[0174] As an example, the vertical length element of the guide hole 335 can be adjusted to a shorter length H1 or a longer length H2, which is the same as maintaining the horizontal length element at VL and adjusting the inclination angle in the oblique direction based on the length direction to A1 or A2.

[0175] In this way, the amount of operation work required by the operation button unit 120 to open the armrest cover 100 can be adjusted by adjusting the inclination angle in the oblique direction of the guide hole 335. That is, the amount of work required by the passenger to open the armrest cover 100 can be adjusted by adjusting the guide hole 335.

[0176] Refer to the above Fig.14 The X-axis represents the moving distance D of the locking rod 380, and the Y-axis represents the amount of operation work W applied to the operation button unit 120. The curve G1 is the same as the above Fig.13a The corresponding curve, curve G2, is the same as the above Fig.13b The corresponding curve.

[0177] In order to open the armrest cover 100, the locking rod 380 needs to move to a moving distance VL. Fig.13a In order to make the lock rod 380 move to the moving distance VL, the center rod 320 needs to move HL1 along the length direction. Therefore, the armrest cover 100 can only be opened by applying the operation work W1 corresponding to the moving distance HL1 of the center rod 320 to the operation button unit 120.

[0178] In contrast, in the above Fig.13b In order to make the locking rod 380 move to the moving distance VL, the center rod 320 needs to move HL2 along the length direction. Only when the amount of operating work W2 corresponding to the moving distance HL2 of the center rod 320 is applied to the operating button unit 120 can the armrest cover 100 be opened.

[0179] That is, in the above Fig.13a In the embodiment, the vehicle occupant can open the armrest cover 100 by performing a relatively small amount of operation work W1, so that the operation button unit 120 can be operated with a smaller force to open the armrest cover 100. Fig.13bIn the embodiment, the vehicle occupant can open the armrest cover 100 only by performing a relatively large amount of operation work W2, and thus the armrest cover 100 can be opened only by operating the operation button unit 120 with a greater force.

[0180] As another example, refer to the above Fig.15a and Fig.15b The amount of operating work required when operating the operating button unit 120 to open the armrest cover 100 can be adjusted by forming the guide hole 335 into an arc shape.

[0181] Above Fig.15a The guide hole 335 is shown to form an arc protruding upward in the diagonal direction. In the initial stage when the passenger starts to operate the operation button unit 120, the movement distance of the locking rod 380 is not large. After a specified time point, the movement distance of the locking rod 380 will increase.

[0182] That is, in a case where the guide hole 335 is formed by an arc protruding from the upper side toward the diagonal direction, in the initial stage when the operation button unit 120 begins to be operated to guide the locking adjustment protrusion 371 to move from the normal position through the guide hole 335, the horizontal movement of the locking adjustment protrusion 371 is small and the vertical movement is large, so the amount of operating work performed by the passenger will not be consumed in the movement of the locking rod 380.

[0183] Starting from the middle position of the locking adjustment protrusion 371 passing through the guide hole 335 and gradually moving to near the end, the vertical movement of the locking adjustment protrusion 371 will become smaller and the horizontal movement will become larger, so the amount of operating work performed by the passenger will be consumed in the movement of the locking rod 380.

[0184] Above Fig.15b The guide hole 335 is shown to form an arc protruding toward the lower side in the diagonal direction. In the initial stage when the passenger starts to operate the operation button unit 120, the movement distance of the locking rod 380 is large. After a specified time point, the movement distance of the locking rod 380 will become small.

[0185] That is, in a case where the guide hole 335 is formed by an arc protruding from the lower side toward the diagonal direction, in the initial stage when the operation button unit 120 begins to be operated to guide the locking adjustment protrusion 371 from the normal position through the guide hole 335, the vertical movement of the locking adjustment protrusion 371 is small and the horizontal movement is large, so the amount of operating work performed by the passenger will be consumed in the movement of the locking rod 380.

[0186] Starting from the middle position of the locking adjustment protrusion 371 passing through the guide hole 335 and gradually moving to near the end, the horizontal movement of the locking adjustment protrusion 371 will become smaller and the vertical movement will become larger, so the amount of operating work performed by the passenger will not be consumed in the movement of the locking rod 380.

[0187] Refer to the above Fig.16a and Fig.16b , the X-axis represents the moving distance D of the locking lever 380, and the Y-axis represents the amount W of the operating work applied to the operating button unit 120. Fig.16a The curve shown in Fig.15a The corresponding curve above Fig.16b The curve shown in Fig.15b The corresponding curve.

[0188] If the amount of operation work EW required from the initial stage of the passenger's operation of the operation button unit 120 to the predetermined time is Fig.15a For the guide hole 335 shown in FIG. 1 , the moving distance of the locking rod 380 will reach MD1, and for the above Fig.15b For the guide hole 335 shown, the moving distance of the locking rod 380 will reach MD2.

[0189] That is, from the initial stage when the passenger operates the operation button unit 120 to the predetermined time, if the passenger performs the same amount of operation work EW, the result will be the same as that of the above-mentioned operation. Fig.15a Compared with the guide hole 335 shown in the figure, the above Fig.15b The illustrated condition of the guide hole 335 would allow the locking bar 380 to move further.

[0190] Furthermore, until the critical position DD is reached where the locking rod 380 is easily disengaged from the locking hole 555 due to a small impact or shaking, if the above-mentioned Fig.15a The guide hole 335 shown in FIG. 1 requires a relatively large amount of operating work DW1, but when using the above-mentioned Fig.15b In the case of the guide hole 335 shown, a relatively small amount of operating work DW2 needs to be consumed.

[0191] In overall comparison, the above Fig.15a The situation shown and the above Fig.15b The illustrated cases all require the same amount of operation work OW for the operation button unit 120 to reach the distance OD for completely drawing out the locking rod 380 from the locking hole 555 .

[0192] However, in the initial stage of operating the operation button unit 120, although the same amount of operation work EW is required for the operation button unit 120, the amount of operation work EW is different from the above-mentioned amount of operation work EW. Fig.15a In contrast, the locking lever 380 is Fig.15b In the case shown, the movement is greater, and only a relatively small amount of operating work DW2 is required to enable the locking lever 380 to reach the critical position DD.

[0193] That is, when the guide hole 335 is formed by an arc protruding upward in the diagonal direction, the armrest cover 100 will not be opened even if the passenger applies a small force or there is an impact, so that the armrest cover 100 can be more stably maintained in the locked state.

[0194] As described above, in the present invention, the length direction is used as a reference to adjust the inclination angle of the guide hole 335 set in the wing 330 in the diagonal direction, or the guide hole 335 is formed in a circular arc shape protruding toward the upper side or the lower side of the diagonal direction to adjust the amount of operating work required by the operating button unit 120 to open the armrest cover 100, thereby applying various changes to the operating feel felt by the passenger when operating the operating button unit 120, and the armrest cover 100 can be stably maintained closed.

[0195] In addition, the armrest box of the present invention can prevent the armrest cover from being opened in both directions at the same time by adopting an armrest opening direction adjustment unit to limit the operation of one of the front operation button unit and the rear operation button unit of the armrest cover when operating the other one, which will be observed through an embodiment.

[0196] Fig.17 An embodiment is shown in which the armrest cover is bidirectionally closed by the armrest cover opening and closing device for bidirectionally opening the armrest cover in the armrest box of the present invention.

[0197] In order to realize the front opening and closing of the armrest cover, a front operation button unit 120a, a front rod component 310a, a front locking control unit 350a, etc. may be included.

[0198] Furthermore, in order to realize rearward opening and closing of the armrest cover, a rearward operation button unit 120b, a rearward rod component 310b, a rearward locking control unit 350b, etc. may be included.

[0199] The front operation button unit 120a, the front rod member 310a, the front lock control unit 350a, and the rear operation button unit 120b, the rear rod member 310b, the rear lock control unit 350b may be arranged symmetrically to each other in the front and rear.

[0200] The front center rod 320a of the front rod part 310a and the rear center rod 320b of the rear rod part 310b may have their respective ends correspond to each other along the length direction.

[0201] The armrest opening direction adjusting unit 600 may be provided at the end portion of the front center rod 320a of the front rod part 310a and the end portion of the rear center rod 320b of the rear rod part 310b.

[0202] Referring to the enlarged internal view of the armrest opening direction adjustment unit 600, the armrest opening direction adjustment unit 600 may include: guide partitions 620a, 620b, used to guide the length direction movement of the front center rod 320a and the rear center rod 320b; and an opening space 610, which can enable the end of one selected from the front center rod 320a and the rear center rod 320b to move.

[0203] Here, the length SD of the open space 610 may correspond to a moving length by which one of the front center rod 320a or the rear center rod 320b may move along the length direction according to an operation performed on one selected from the front operation button unit 120b or the rear operation button unit 120b.

[0204] That is, when the armrest cover is closed in both directions, the distance at which the ends of the front center rod 320a and the rear center rod 320b contact each other as the armrest cover is opened from one direction may be set as the length SD of the open space 610 .

[0205] As mentioned above Fig.17 As shown, when the front of the armrest cover is closed by the front locking control unit 350a and the rear of the armrest cover is closed by the rear locking control unit 350b, the separation distance between the end of the front center rod 320a and the end of the rear center rod 320b can be maintained at SD by the armrest opening direction adjustment unit 600.

[0206] Fig.18 An embodiment is shown in which the front side of the armrest cover is opened and the rear side is closed by the armrest cover opening and closing device for bidirectional opening of the armrest cover in the armrest box of the present invention.

[0207] According to the operation of the front operation button unit 120b, the front center rod 320a of the front rod member 310a is pushed toward the rear in the length direction. The end portion of the front center rod 320a can be guided by the guide partitions 620a, 620b of the armrest opening direction adjustment unit 600 and move toward the rear in the length direction, thereby contacting the end of the rear center rod 320b.

[0208] As the front center rod 320a moves, the locking rod of the front locking control unit 350a may be drawn out from the locking hole, thereby opening the front of the armrest cover.

[0209] When the front of the armrest cover is opened, the end of the front center rod 320a and the end of the rear center rod 320b are brought into contact with each other by the armrest opening direction adjusting unit 600, thereby restricting the movement of the rear center rod 320b.

[0210] That is, when the front of the armrest cover is opened, the armrest opening direction adjustment unit 600 makes the rear center rod 320b unable to move, and even if the rear operation button unit 120b is operated, the rear center rod 320b cannot move, thereby limiting the rear opening of the armrest cover when the front of the armrest cover is opened.

[0211] Similarly, when the rear side of the armrest cover is opened, the front center rod 320a cannot be moved by the armrest opening direction adjustment unit 600. Even if the front operation button unit 120b is operated, the front center rod 320a cannot be moved, thereby limiting the front opening of the armrest cover when the rear side of the armrest cover is opened.

[0212] As described above, in the present invention, the armrest opening direction adjusting unit can be used to selectively control the opening direction of the armrest cover in a two-way opening armrest box, thereby solving the problem of the armrest cover itself being separated due to the front and rear of the armrest cover being opened simultaneously.

[0213] As described above through the embodiments of the present invention, the present invention can stably and highly reliably realize the opening and closing operations of the armrest cover.

[0214] In particular, by providing a guide hole in an oblique direction in a rod part that moves along the length direction according to the operation of an operating button, the horizontal movement of the locking rod can be controlled by the guidance of the guide hole, thereby achieving stable and highly reliable opening and closing of the armrest cover with a simple structure.

[0215] In addition, by adjusting the inclination angle along the diagonal direction of the guide hole for guiding the opening of the armrest cover, or by forming a guide hole with an arc protruding toward the upper or lower side of the diagonal direction, the amount of operating work required by the operating button unit to open the armrest cover can be adjusted, thereby feeling a different operating feel.

[0216] The above description is only an illustrative description of the technical idea of ​​the present invention. As long as one is a person of ordinary skill in the technical field to which the present invention belongs, various modifications and variations can be implemented without departing from the essential features of the present invention. Therefore, the multiple embodiments described in the present invention are not used to limit the technical idea of ​​the present invention, but are used to illustrate the present invention, and the technical idea of ​​the present invention is not limited to these embodiments. The protection scope of the present invention should be interpreted according to the scope of protection of the attached invention claims, and all technical ideas within the same scope should be interpreted as included in the scope of rights of the present invention.
