Description

Technical Field

[0001] The invention relates to a concealed bracket for holding items, and more particularly to a concealed bracket for vehicles. Background Technology

[0002] On vehicles (such as cars, trains, train carriages, and airplanes), convenient devices are installed near passenger seats to meet people's needs for retrieving items. For example, vehicles may have holders for holding beverage containers.

[0003] The bracket can be located on the armrest between the driver's seat and the passenger seat, allowing the driver and passenger to hold different types of beverage containers (such as cans, bottles, and cups) in the bracket.

[0004] Known brackets are typically formed as single or double brackets with a generally cylindrical receiving portion. Brackets usually also include multiple fingers or retaining elements to hold beverage containers with a diameter smaller than the total diameter of the receiving portion.

[0005] To save space and keep the interior tidy, a retractable bracket is proposed. The technology allows for a hidden bracket design, meaning that the bracket retracts when not in use and extends when needed.

[0006] However, this bracket has some issues. For example, since cups or water bottles have a certain height, the bracket also needs to be of a certain height to stably support them. However, due to limited space inside the car or armrest, setting the bracket too high could take up too much space, which would negatively impact the armrest design. On the other hand, if the bracket is not high enough, it might reduce its stability.

[0007] Furthermore, existing brackets are only for use by people on their sides, not those behind them. For example, the bracket on the center console in the front of the vehicle is only for the driver and front passenger, not for rear passengers.

[0008] That is, the problem with the existing hidden bracket is that if the hidden bracket is fixed on the rotatable mechanism, when the hidden bracket is rotated 180 degrees backward in the front-back direction through the rotatable mechanism, the bottom and top positions of the hidden bracket after rotation change and it cannot accommodate the cup. As a result, the hidden bracket in the existing technology cannot be used by people in the back row.

[0009] Therefore, there is a need for further improvement of the existing brackets.

[0010] The information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0066] Unless otherwise stated, the same reference numerals or symbols indicate the same elements in the accompanying drawings.

[0067] It should be understood that the accompanying drawings are not necessarily drawn to scale, but rather present simplified representations of various features to illustrate the basic principles of the invention. Specific design features disclosed in this invention (including, for example, specific dimensions, orientations, positions, and shapes) will be determined in part by the specific environment in which they are intended for application and use.

[0068] Throughout these figures, the same reference numerals denote the same or equivalent parts of the invention. Detailed Implementation

[0069] Reference will now be made in detail to various embodiments of the invention, examples of which are presented in the accompanying drawings and described below. Although the invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the invention to these exemplary embodiments. Rather, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit of the invention and the scope defined by the appended claims.

[0070] This invention relates to a concealed bracket device that can be located on the handrail of a mobile vehicle. Furthermore, the bracket device can be mounted on a rotatable mechanism (such as a vehicle handrail) that allows the bracket device to be used by passengers in the front and rear rows by rotation.

[0071] Below, please refer to the appendix. Figures 3-24 The concealed bracket device of the present invention will be described in detail below.

[0072] like Figures 3-4 As shown, the concealed bracket device of the present invention can install a concealed bracket assembly on the armrest of the front seat of a vehicle, the armrest being rotatable back and forth (see...). Figure 3 and Figure 4 Furthermore, the bracket device can extend and retract from the handrail, so it can be used by both front and rear passengers.

[0073] See Figure 9 , Figure 10 The concealed bracket device of the present invention includes: a fixed component, a movable component, and a return spring; wherein the movable component is housed in the fixed component and is movable in and out relative to the fixed component; the movable component has a retractable bracket component for accommodating articles; and the two ends of the return spring are respectively mounted on the fixed component and the movable component.

[0074] The fixing assembly includes: a fixing cover plate, a guide rail, and a rack; the fixing cover plate is composed of an upper cover plate 1 and a lower cover plate 2, which together form a housing for accommodating the movable assembly; the front end of the housing is provided with an opening, through which the movable assembly moves in or out. The guide rail is used to guide the movement of the movable assembly.

[0075] The guide rails include a left guide rail and a right guide rail; wherein the left and right guide rails are respectively disposed on the side of the fixed upper cover plate. The moving component is provided with guide blocks, which are arranged in guide rail grooves. In this embodiment, the left guide rail 3 and the right guide rail 4 are respectively disposed on the left and right sides of the upper cover plate 1, and the left guide rail 3 and the right guide rail 4 are respectively provided with guide rail grooves.

[0076] A rack is provided on both sides of the lower cover plate 2. Alternatively, a rack may be provided on only one side of the lower cover plate 2.

[0077] The arrangement of the left and right guide rails and the rack can be varied. For example, the left guide rail 3 and the right guide rail 4 can be set on the lower cover plate 2, while the rack can be set on the upper cover plate 1.

[0078] The first end of the return spring 6 is located at the rear of the moving component, and the second end is located at the front of the fixed component, so as to push the moving component forward by the elastic force of the return spring, thereby moving the moving component out of the fixed component. In this embodiment, the second end of the return spring 6 is located at the front of the lower cover plate 2.

[0079] See Figure 11 , Figure 12 The movable component includes a movable housing, a power transmission device, and a bracket assembly; when the movable component moves back and forth, the power transmission device transmits power to the bracket assembly. The movable component 8 is disposed within the space formed by the upper cover plate 1 and the lower cover plate 2, and is moved out of the fixed component by the action of the return spring 6.

[0080] The movable component 8 includes: a movable upper cover 9, a movable lower cover 10, an end 11, a guide block 12, a movable gear 13, a balance gear 14, a rotating gear 15, and a bracket device 16.

[0081] The movable upper cover 9 and movable lower cover 10 together form a housing to accommodate the bracket assembly 16, the various gears, and the ends of the return spring. The front of the housing formed by the movable upper cover 9 and movable lower cover 10 has an opening, through which the upper extension portion 20 and the lower extension portion 23 of the bracket body can extend, respectively, from the corresponding openings of the movable upper cover 9 and movable lower cover 10. Sliding grooves are provided on the edges of the openings of the movable upper cover 9 and movable lower cover 10; Figure 23 The image shows a groove along the edge of the opening of the movable lower cover 10.

[0082] The gear includes a moving gear 13, a rotating gear 15, and a gear ring. The driving gear meshes with a first rack located on a fixed assembly; the gear ring is disposed on the bracket body of the bracket assembly, and the transmission gear is located between the driving gear and the gear ring.

[0083] The movable gear 13 and the rotating gear 15 are rotatably mounted on the movable upper cover and / or lower cover (in the illustrated embodiment, they are disposed on the movable lower cover). The movable gear 13 includes two gears, wherein the lower gear 131 meshes with a rack on the lower cover plate 2, and the upper gear 132 is fixedly connected to the lower gear and meshes with the rotating gear 15. The rotating gear 15 meshes with a gear ring on the bracket body 22, thereby converting the movement of the movable component relative to the fixed component into the rotation of the bracket body 22 through the respective gears (described in detail below).

[0084] The movable component may also be provided with a balancing gear 14. This balancing gear 14 meshes with a second rack located on the fixed component, the second rack being positioned on the side opposite to the first rack on the fixed component. A balancing movable gear 13 is used to balance the biasing force generated due to the meshing of the movable gear 13 with the first rack.

[0085] The gears described above are only intended to convert the movement of the moving component relative to the fixed component into the rotation of the bracket body 22. Therefore, the configuration of these gears can be changed. For example, the moving gear and the rotating gear can be configured as one (i.e., meshing with the first rack on one side and the gear ring on the other side) to reduce the number of components; or the balancing gear can be omitted.

[0086] The moving component also includes an end plate 11, which is located at the front end of the moving component.

[0087] The bracket assembly 16 includes a bracket body 22, a gear ring, an upper extension portion 20, and a lower extension portion 23. The bracket body 22 is a hollow cylindrical body. The gear ring is arranged on the outer periphery of the bracket body 22 and drives the bracket body 22 to rotate through connection with a power transmission device. The upper extension portion 20 and the lower extension portion 23 are capable of moving up and down relative to the bracket body 22. When the moving assembly moves forward, the bracket body 22 rotates due to the power transmitted by the power transmission device, thereby causing the upper extension portion 20 and the lower extension portion 23 to move up and down.

[0088] The bracket body 22 is disposed in the space formed by the movable upper cover 9 and the movable lower cover 10. The upper and lower ends of the bracket body 22 are rotatably mounted in the sliding grooves of the movable upper cover 9 and the movable lower cover 10, respectively, and are capable of rotating within them. See Appendix. Figure 22 It shows that the lower end of the bracket body 22 is installed in the groove of the movable lower cover 10.

[0089] The wall of the bracket body 22 is H-shaped, that is, it has an inner wall and an outer wall. The middle of the inner wall and the outer wall is connected by a horizontally extending cross arm, thereby forming two grooves with openings facing upward and downward respectively. The upper extension portion 20 is arranged in the upper groove, while the lower extension portion 23 is arranged in the lower groove. When the bracket body 22 rotates, the upper and lower extension portions do not rotate relative to the movable upper cover 9 and the movable lower cover 10.

[0090] A portion of the outer wall of the bracket body 22 is provided with an arc-shaped rack for meshing with the drive gear 15. The length of the rack matches the length of the guide groove (described in detail below). When the moving component is fully retracted inside the fixed component, one end of the rack meshes with the drive gear 15, and when the moving component is fully removed, the other end meshes with the drive gear 15. (See attached...) Figure 14 and Figure 16 As shown, the rack extends at an angle equal to or less than 90 degrees.

[0091] The bracket body 22 has a guide groove on its wall, and the extendable portion is provided with a guide pin 21; the guide pin is arranged in the guide groove. When the bracket body 22 rotates, the extendable portion moves in the vertical direction through the engagement of the guide pin 21 with the guide groove.

[0092] The guide groove includes a horizontal section and an inclined section, with the inclined section located at the end of the horizontal section. The extendable portion includes an upper extendable portion and a lower extendable portion. The upper extendable portion is located at the upper part of the cup body and is capable of upward movement, while the lower extendable portion is located at the lower part of the cup body and is capable of downward movement. The guide groove includes an upper guide groove and a lower guide groove; the inclined portion of the upper guide groove slopes upward, and the inclined portion of the lower guide groove slopes downward.

[0093] In an embodiment of the present invention, three guide slots are provided, and correspondingly, three guide pins 21 are provided on the upper extension portion 20 and the lower extension portion 23, respectively. The number of guide slots can be varied, for example, between 2 and 8, with three being preferred. The guide slots can penetrate the outer wall of the bracket body 22, but may or may not penetrate the outer wall.

[0094] Guide pins 21 are located near the lower edge of the upper extension portion 20 and near the upper edge of the lower extension portion 23, respectively, that is, on the inner sides of the upper extension portion 20 and the lower extension portion 23. These pins 21 are inserted into guide slots in the bracket body 22. The number of these pins is the same as the number of guide slots.

[0095] When the movable component is removed, the bracket body 22 rotates under the drive of the movable gear 13 and the rotating gear 15. When the movable component is still inside the housing within the upper and lower cover plates, the guide pin 21 is in the horizontal section of the guide groove of the bracket body 22. Therefore, although the bracket body 22 rotates, the upper extension portion 20 and the lower extension portion 23 do not move up and down and remain stationary. When the movable component moves out of the housing formed by the movable upper cover 9 and the movable lower cover 10 and is outside the housing, the guide pin 21 enters the inclined section of the guide groove and moves up and down respectively as the bracket body 22 rotates, thereby driving the upper extension portion 20 and the lower extension portion 23 to move up and down respectively from the openings of the movable upper cover 9 and the movable lower cover 10, thereby increasing the distance between the upper edge of the upper extension portion 20 and the lower edge of the lower extension portion 23, that is, increasing the overall height of the bracket assembly 16. See [reference needed]. Figure 17 .

[0096] The horizontal and inclined sections of the guide groove ensure that when the bracket device 16 is not removed from the fixed component, the upper extension portion 20 and the lower extension portion 23 will not move to the upper and lower sides, thus avoiding contact with the upper cover plate 1 and the lower cover plate 2, and preventing interference with the movement of the component. When the bracket device 16 moves out of the fixed component, the upper extension portion 20 and the lower extension portion 23 move to the upper and lower sides respectively, thereby increasing the distance between the upper edge of the upper extension portion 20 and the lower edge of the lower extension portion 23 to better hold the cup.

[0097] The extendable portion includes foldable flaps. The upper flap 17 and lower flap 18 are located on the outer sides of the upper extension portion 20 and lower extension portion 23, respectively, opposite to the guide pin 21. Specifically, the upper flap 17 and lower flap 18 are located on the upper side of the upper extension portion 20, and the lower flap 18 is located on the lower side of the lower extension portion 23. This arrangement maximizes the distance between the flaps of the upper / lower extension plates and the edges of the lower / upper extension plates. Of course, the flaps can also be positioned in other locations on the upper and lower extension plates.

[0098] As shown in the figure, there are three upper lobes 17 and three lower lobes 18, but their number can be varied, for example, from 1 to 8.

[0099] The upper petal 17 and lower petal 18 each include a petal body, a spring, and a hinge shaft. The petal body is rotatably mounted on the upper extension portion 20 or the lower extension portion 23 via the hinge shaft. The spring is positioned between the petal body and the extension plate, thereby providing a restoring force to the petal body. When the petal body is in its original position, both the upper and lower petals are in a vertical position, while in the extended position they are in a horizontal position; when in the horizontal position, the spring applies a restoring force to the petal body.

[0100] The upper and lower lobes rotate about a hinge axis, with a rotation angle of approximately 90 degrees. Specifically, the lower lobe rotates from an upward vertical position to a horizontal position; that is, in the folded state, the lower lobe is in an upward vertical position, and in the unfolded state, the lower lobe is in a horizontal position to accommodate the cup. Similarly, the upper lobe rotates from a downward vertical position to a horizontal position; that is, in the folded state, the lower lobe is in a downward vertical position, and in the unfolded state, the lower lobe is in a horizontal position to accommodate the cup.

[0101] Although in this embodiment the upper and lower lobes are configured to be rotatable, they can also be configured to be fixed.

[0102] Stops can be provided on the petals to limit further rotation when the petals rotate to a horizontal position, thereby keeping the cup in place.

[0103] like Figure 10 and Figure 24 As shown, the present invention may further include a locking device 7, which includes a locking pin and a locking groove; wherein the locking pin is arranged at the rear end of the fixed component; the locking groove is arranged at the rear end of the movable component; of course, the positions of the locking pin and the locking groove can be interchanged, that is, the locking groove is arranged at the rear end of the fixed component; the locking pin is arranged at the rear end of the movable component.

[0104] The locking groove forms a locking pin insertion channel and a locking pin removal channel. (In the attached...) Figure 24 The locking pin insertion channel is located on the right, and the locking pin removal channel is located on the left. When the moving component is inside the fixed component, the locking pin is in its fixed position in the channel (i.e., the position shown in the attached diagram). When the operator pushes the moving component backward, the locking pin moves to the locking pin locking groove channel under the action of the rear wedge, thereby moving the moving component out of the fixed component under the action of the spring. When the moving component is in the removed position, and the operator pushes the moving component backward, the moving component moves into the fixed component against the spring force. At this time, the locking pin enters through the locking pin insertion channel. Then, when the operator releases the hand, the locking pin is positioned at the fixed point of the locking groove under the action of the spring, thereby keeping the moving component inside the fixed component.

[0105] The operation process of the concealed bracket device of the present invention will be described below.

[0106] The concealed bracket device of the present invention is in a position when not in use. Figure 10The described storage state refers to the movable component being located inside the fixed component. When the user needs to use the bracket device of the present invention, they press the decorative panel 11 inward. When external force is applied to the decorative panel 11, the locking device 7 unlocks the movable component 8. Under the elastic force of the spring, the movable component moves outward, driving the gear 13 to mesh with the rack, thereby causing the bracket body to rotate. When the movable component is inside the fixed component, the guide pin is in the horizontal section of the guide groove, so although the bracket body rotates, the upper and lower extension parts do not move. Once the movable component moves out of the fixed component, the guide pin enters the inclined section of the guide groove. The guide pin moves upward or downward under the influence of the inclined section of the guide groove, thereby causing the upper and lower extension parts to move upward and downward respectively. When the guide block of the movable component contacts the end of the guide rail groove and is limited, the movable component stops moving. At this time, the upper and lower extension parts also stop extending outward, and the distance between their upper and lower edges is at its maximum, thereby ensuring stable holding of the cup.

[0107] When it is necessary for the movable component to retract and be accommodated within the fixed component, the movable component is pushed inward until the locking pin is positioned at the fixed point of the locking groove, thereby holding the movable component in place.

[0108] If a passenger in the rear seat needs to use the concealed bracket device of the present invention, the concealed bracket device needs to be flipped 180 degrees backward, so that the upper cover 1 of the fixing component is on the lower side and the lower cover 2 is on the upper side. Then, press the trim panel 11 inward to move the moving component out. The subsequent operations are the same as before.

[0109] Although the illustrated embodiment of the present invention includes an extendable portion comprising an upper extendable portion and a lower extendable portion, and the upper extendable portion and the lower extendable portion respectively include an upper folding flap and a lower folding flap; however, the present invention is not limited thereto and can be modified as appropriate.
