Description

Technical Field

[0001] This utility model relates to the field of automotive armrest box technology, specifically to a rotating armrest box. Background Technology

[0002] A car armrest is a car accessory installed between two seats, belonging to the automotive interior system. Its ergonomic design aims to provide a place for the driver's arm to rest during long drives, preventing soreness, numbness, and stiffness. Nowadays, there are increasingly more functional improvements to armrests. Currently, the armrest covers of car armrest boxes generally adopt a sliding structure, that is, the armrest cover slides with the box body through a slide rail, so that the armrest cover moves in a fixed direction, or a flip-top mechanism is used, in which the armrest cover is hinged to the box body so that the armrest cover can be flipped to realize the opening or closing function of the box body.

[0003] While this design meets basic storage needs, regardless of whether it's a sliding or flip-top structure, the armrest cover surface always remains parallel to the cabinet or at a fixed angle, unable to rotate around a vertical axis in the horizontal plane. When the driver's arm is naturally placed at a certain angle, the fixed angle of the armrest cover reduces the contact area between the arm and the support surface, forcing the driver to adjust their arm posture to fit the cover. Maintaining a single posture for extended periods can easily lead to arm soreness, numbness, and stiffness. Consequently, some existing armrest boxes cannot dynamically adjust the support angle according to different driving habits, resulting in poor personalized adaptability. Utility Model Content

[0004] In view of this, the present invention provides a rotating armrest box, which allows the angle of the armrest cover to be adjusted by rotating it in the horizontal plane. According to one's own driving habits, the tilt angle of the armrest cover can be adjusted so that the driver's arm is fully in contact with the support surface, thereby reducing fatigue and improving personalized adaptability.

[0005] To solve the above-mentioned technical problems, this utility model provides a rotating armrest box, including a box body and an armrest cover installed on the supporting plane of the box body. A pin is fixed on the upper surface of the box body, perpendicular to the supporting plane. A connector is provided at the bottom of the armrest cover. The armrest cover can be rotatably hinged to the pin through the connector. Through the hinge, the connector and the armrest cover can rotate together about the central axis of the pin. When the armrest cover is rotated, the armrest cover rotates in the horizontal plane around the pin, thereby tilting the armrest cover to adjust the horizontal tilt angle of the armrest cover, so that the driver's arm is fully in contact with the supporting surface, thereby reducing fatigue and improving the driver's comfort in the vehicle.

[0006] The connector includes a connecting frame located at the bottom of the armrest cover, with a pin hole through the center of the connecting frame. The connecting frame is sleeved above the pin shaft through the pin hole, so that the pin shaft and the connecting frame form a hinged engagement. Thus, when the armrest cover is rotated, the armrest cover will drive the connecting frame to rotate together. The connecting frame engages with the pin shaft through the pin hole, so that the connecting frame rotates horizontally about the center of the pin shaft, thereby allowing the armrest cover to tilt at an angle.

[0007] The connector also includes a fixed frame fixed to the bottom of the armrest cover. The fixed frame is equipped with a sliding component. The fixed frame can slide linearly with the connecting frame through the sliding component. The fixed frame slides with the connecting frame through the sliding component, so that the armrest cover can slide with the connecting frame while being hinged and rotated through the connecting frame and the pin. This allows the armrest cover to slide and rotate simultaneously, increasing the range of motion of the armrest cover.

[0008] The sliding component includes a slide rail fixedly mounted within a fixed frame. The two side walls of the connecting frame are fitted against the inner side wall of the slide rail, allowing the connecting frame to slide linearly along the slide rail. A groove is provided at the bottom of the fixed frame, passing through the slide rail, and a pin passes through the groove, allowing the fixed frame and the pin to slide together. The pin also passes through a pin hole in the center of the connecting frame. Thus, when the armrest cover is slid, the armrest cover drives the fixed frame to slide along the slide rail and onto the connecting frame, while the connecting frame itself does not slide. The groove at the bottom of the fixed frame and the pin simultaneously slide together. When the armrest cover needs to be rotated, the fixed frame drives the connecting frame to rotate together via the slide rail. This allows the armrest cover and the fixed frame to not only slide but also rotate together with the connecting frame around the center of the pin, thus achieving a combination of sliding and rotating engagement of the armrest cover.

[0009] The pin consists of a protruding block, a fixed shaft, and a limiting block. The protruding block is set on the supporting plane of the housing. When the lower part of the fixed frame is attached to the supporting plane of the housing, the protruding block will be located in the sliding groove, so that the fixed frame and the protruding block are in sliding engagement through the sliding groove. The upper end of the protruding block is provided with a fixed shaft that matches the pin hole. The fixed shaft is inserted into the pin hole of the connecting frame to realize the hinge engagement between the connecting frame and the pin. The upper end of the fixed shaft is fixed with a limiting block. The diameter of the limiting block is larger than the diameter of the pin hole. The limiting block can limit the connecting frame to prevent the pin hole of the connecting frame from disengaging from the fixed shaft, thereby connecting the connecting frame and the fixed frame together, so that the fixed frame is always connected to the housing.

[0010] Multiple grooves are evenly distributed on the circumferential surface of the limiting block. Each pair of adjacent grooves forms a central angle through the central axis of the limiting block, and the central angles between each pair of adjacent grooves are the same. The connecting frame is equipped with a rotation positioning component. When the armrest cover is rotated to a specified angle, the rotation positioning component can cooperate with the grooves on the limiting block to limit the connecting frame and the armrest cover, so that the armrest cover maintains its angular position after rotation.

[0011] The rotary positioning assembly includes two guide seats arranged along the length of the connecting frame, and the two guide seats are symmetrically distributed on both sides of the pin hole. A positioning block is slidably fitted inside the guide seat, and an elastic element is connected between the positioning block and the guide seat. The elastic element can push the positioning block to slide, so that the positioning block can be embedded in the groove. Through the cooperation between the positioning block and the guide seat, the connecting frame can achieve the function of angle positioning. Since the connecting frame slides linearly with the fixed frame through the slide rail, the fixed frame and the armrest cover can also achieve angle positioning.

[0012] The guide seat has a U-shaped structure, and the two side walls of the positioning block are fitted with the two inner side walls of the guide seat, allowing the positioning block to slide against the U-shaped inner wall of the guide seat. Since the opening of the guide seat faces the circumferential surface of the limiting block, the positioning block slides linearly within the guide seat and embeds into the groove of the limiting block. The elastic element is a compression spring, with its two ends fixed to the inner wall of the U-shaped structure and the side of the positioning block, respectively. The end of the positioning block has an arc surface that matches the groove. When the armrest cover rotates, the fixed frame drives the connecting frame to rotate synchronously around the axis of the fixed shaft. At this time, the connecting frame drives the guide seat and the positioning block to rotate synchronously. During the rotation, since the end of the positioning block and the groove are also matching arc surfaces, when the positioning block leaves the initial groove, the positioning block will move away from the limiting block under the guiding sliding action of the guide seat. At this time, the positioning block will compress the compression spring. When it rotates to the next adjacent groove, the rebound force of the compression spring will push the positioning block to move towards the limiting block, so that the positioning block is embedded in the groove, thereby limiting the rotation angle of the armrest cover. While controlling the rotation angle of the armrest cover, the positioning block and the groove of the limiting block can be used to position the armrest cover after rotation, improving the stability of the armrest cover after rotation.

[0013] The central angle between each two adjacent grooves is 15 degrees. Therefore, through the design of the positioning block, the armrest cover can rotate at least 15 degrees each time it rotates, thereby controlling the rotatable angle of the armrest cover.

[0014] Two limiting protrusions extend symmetrically from the circumferential surface of the limiting block. With the opening of the flip cover of the box as the positive reference, the two limiting protrusions are symmetrically arranged on both sides of the limiting block. When the armrest cover is rotated 60 degrees counterclockwise from the positive reference, the positioning block will be embedded in the designated groove, and the end of the guide seat on one side will abut against the side wall of the right limiting protrusion. The counterclockwise rotation will make the end of the armrest cover face the position of the driver's seat in the car, so that the driver's arm can be bent and fit against the armrest cover, improving comfort. In addition, limiting the rotation angle of the armrest cover also controls the rotation range to a certain extent, reducing the probability of damage to internal parts due to excessive rotation.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. When using this utility model, the angle of the armrest cover can be adjusted by rotating it in the horizontal plane. According to one's own driving habits, the tilt angle of the armrest cover can be adjusted so that the driver's arm is fully in contact with the support surface, thereby reducing fatigue and improving personalized adaptability.

[0016] 2. When this utility model is used, the fixed frame drives the slide groove to move along the pin shaft while the connecting frame remains stationary during sliding. During rotation, the slide rail links the connecting frame to rotate around the shaft. With the 15° indexing positioning structure, the motion accuracy is ensured while avoiding functional interference, and the degree of adjustment is greatly expanded.

[0017] 3. When this utility model is used, the sliding cooperation between the fixed frame and the connecting frame, and the hinge cooperation between the connecting frame and the fixed shaft, enable the armrest cover to achieve a combination of sliding and rotation functions, thereby greatly improving the degree of adjustment freedom.

[0018] 4. When using this utility model, the modular design allows for detachable connections between the fixed frame and the handrail cover, and between the fixed frame and the box body, improving the convenience of later maintenance and installation. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-11 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] Rotating armrest box, according to Figure 1-4 As shown: It includes a housing 100 and an armrest cover 200 mounted on the supporting plane of the housing 100. A pin 500 perpendicular to the supporting plane is fixed on the upper surface of the housing 100. The bottom of the armrest cover 200 is provided with a connector. The armrest cover 200 can be rotatably hinged to the pin 500 through the connector. Through the hinge, the connector and the armrest cover 200 can rotate together about the central axis of the pin 500. When the armrest cover 200 is rotated, the connector transmits the rotational force to the pin 500, so that the armrest cover 200 rotates around the pin 500 in the horizontal plane. This allows the armrest cover 200 to be rotated and tilted to adjust the tilt angle of the armrest cover 200, so that the driver's arm can fully fit with the supporting surface, thereby reducing fatigue and improving the driver's comfort in the vehicle. Specifically, such as Figure 3 As shown, the connector includes a connecting frame 300 located at the lower part of the armrest cover 200. A pin hole 301 is provided through the center of the connecting frame 300. The connecting frame 300 is sleeved above the pin shaft 500 through the pin hole 301, so that the pin shaft 500 and the connecting frame 300 form a hinged engagement. Thus, when the armrest cover 200 is rotated, the armrest cover 200 will drive the connecting frame 300 to rotate together. The connecting frame 300 engages with the pin shaft 500 through the pin hole 301, so that the connecting frame 300 rotates horizontally about the center of the pin shaft 500, thereby allowing the armrest cover 200 to tilt at an angle.

[0023] Specifically, such as Figure 3 and Figure 4As shown, the connector also includes a fixed frame 400 fixed to the bottom of the armrest cover 200. The fixed frame 400 is provided with a sliding member. The fixed frame 400 can slide linearly with the connecting frame 300 through the sliding member. The fixed frame 400 and the connecting frame 300 slide together through the sliding member, so that the armrest cover 200 can be hinged and rotated with the pin 500 through the connecting frame 300, and can also slide together with the connecting frame 300. This allows the armrest cover 200 to slide and rotate at the same time, increasing the range of motion of the armrest cover 200.

[0024] Furthermore, such as Figure 4 As shown, the sliding component includes a slide rail 401 fixedly installed in the fixed frame 400. The cross-section of the connecting frame 300 and the cross-section of the slide rail 401 are both rectangular, and the two side walls of the connecting frame 300 are in contact with the inner side wall of the slide rail 401, so that the connecting frame 300 can slide in a straight line with the slide rail 401. The bottom of the fixed frame 400 has a groove 402 that passes through the slide rail 401. The pin 500 can pass through the groove 402, so that the fixed frame 400 and the pin 500 are in sliding engagement. The pin 500 passes through the pin hole 301 in the center of the connecting frame 300. So when the armrest cover 200 is slidable, the armrest cover 200 drives the fixed frame 400 to slide with the connecting frame 300 through the slide rail 401, while the connecting frame 300 itself does not slide. The groove 402 at the bottom of the fixed frame 400 and the pin 500 are in sliding engagement at the same time. When the armrest cover 200 needs to be rotated, the fixed frame 400 will drive the connecting frame 300 to rotate together through the slide rail 401. So the armrest cover 200 and the fixed frame 400 can not only slide, but also rotate together with the connecting frame 300 about the center of the pin 500. Thus, the function of the armrest cover 200 combining sliding and rotation engagement is realized.

[0025] according to Figure 5-8 As shown, the pin 500 is composed of a protrusion 501, a fixed shaft 502 and a limiting block 503. The protrusion 501 is set on the support plane of the housing 100. When the lower part of the fixed frame 400 is attached to the support plane of the housing 100, the protrusion 501 will be located in the slide groove 402, so that the fixed frame 400 and the protrusion 501 are in sliding engagement through the slide groove 402. The upper end of the protrusion 501 is provided with a fixed shaft 502 that is adapted to the pin hole 301. The fixed shaft 502 is inserted into the pin hole 301 of the connecting frame 300 to realize the hinged engagement between the connecting frame 300 and the pin shaft 500. The upper end of the fixed shaft 502 is fixed with a limit block 503. The diameter of the limit block 503 is larger than the diameter of the pin hole 301. The limit block 503 can limit the connecting frame 300 to prevent the pin hole 301 of the connecting frame 300 from disengaging from the fixed shaft 502, thereby connecting the connecting frame 300 and the fixed frame 400 together, so that the fixed frame 400 is always connected to the housing 100.

[0026] according to Figure 9-10 As shown, multiple grooves 506 are evenly provided on the circumferential surface of the limiting block 503. Every two adjacent grooves 506 form a central angle through the central axis of the limiting block 503, and the central angle between every two groups of adjacent grooves 506 is the same. The connecting frame 300 is equipped with a rotation positioning component. When the armrest cover 200 is rotated to a predetermined angle, the rotation positioning component can cooperate with the groove 506 on the limiting block 503 to limit the connecting frame 300 and the armrest cover 200, so that the armrest cover 200 maintains its angular position after rotation.

[0027] Specifically, such as Figure 10 As shown, the rotation positioning assembly includes: Two guide seats 302 are arranged along the length of the connecting frame 300, and the two guide seats 302 are symmetrically distributed on both sides of the pin hole 301. A positioning block 303 is slidably fitted inside the guide seat 302, and an elastic element is connected between the positioning block 303 and the guide seat 302. The elastic element can push the positioning block 303 to slide, so that the positioning block 303 can be embedded in the groove 506. Since the limiting block 503 is fixed, the angle positioning function of the connecting frame 300 can be achieved through the cooperation of the positioning block 303 and the guide seat 302. Since the connecting frame 300 slides only linearly with the fixed frame 400 through the slide rail 401, the angle positioning of the fixed frame 400 and the armrest cover 200 can also be achieved.

[0028] Specifically, such as Figure 10 As shown, the central angle between any two adjacent grooves 506 is 15 degrees. Therefore, through the design of the positioning block 303, the armrest cover 200 can rotate at least 15 degrees each time it rotates. Each time the armrest cover 200 rotates 15 degrees, it is classified as one position. Therefore, a counterclockwise rotation of 60 degrees results in four positions, thereby controlling the rotatable angle of the armrest cover 200.

[0029] Furthermore, such as Figure 10As shown, the guide seat 302 has a U-shaped structure, and the two side walls of the positioning block 303 are in contact with the two inner side walls of the guide seat 302, so that the positioning block 303 can slide against the U-shaped inner wall of the guide seat 302. Since the opening of the guide seat 302 faces the circumferential surface of the limiting block 503, the positioning block 303 slides linearly in the guide seat 302 and is embedded in the groove 506 of the limiting block 503. The elastic element is a compression spring 304, with its two ends fixed to the inner wall of the U-shaped structure and the side of the positioning block 303, respectively. The end of the positioning block 303 has an arc surface that matches the groove 506. When the armrest cover 200 rotates, the fixed frame 400 drives the connecting frame 300 to rotate synchronously around the axis of the fixed shaft 502. At this time, the connecting frame 300 drives the guide seat 302 and the positioning block 303 to rotate synchronously. During the rotation, since the end of the positioning block 303 and the groove 506 also have matching arc surfaces, when the positioning block 303 disengages from the initial groove 506, the positioning block 303 will move away from the limiting block 503 under the guiding sliding action of the guide seat 302. When the armrest cover 200 rotates, the positioning block 303 compresses the compression spring 304 until it rotates to the next adjacent groove 506. At this time, the rebound force of the compression spring 304 will push the positioning block 303 to move towards the limiting block 503, so that the positioning block 303 is embedded in the groove 506. This limits the rotation angle of the armrest cover 200, thereby controlling the rotation angle of the armrest cover 200. At the same time, through the cooperation between the positioning block 303 and the groove 506 of the limiting block 503, the armrest cover 200 can be positioned after rotation, improving the stability of the armrest cover 200 after rotation.

[0030] Furthermore, such as Figure 10 As shown, two limiting protrusions 507 extend symmetrically from the circumferential surface of the limiting block 503. With the orientation of the opening of the flip cover of the box 100 as the positive reference, the two limiting protrusions 507 are symmetrically arranged on both sides of the limiting block 503. When the armrest cover 200 is rotated 60 degrees counterclockwise from the positive reference, the positioning block 303 will be embedded in the designated groove 506, and the end of the guide seat 302 will abut against the side wall of the right limit protrusion 507. The counterclockwise rotation will make the end of the armrest cover 200 face the position of the driver's seat in the car, so that the driver's arm can be bent and fit on the armrest cover 200, improving comfort. In addition, the limitation of the rotation angle of the armrest cover 200 also controls the rotation range to a certain extent, reducing the probability of damage to internal parts due to excessive rotation. When the armrest cover 200 is rotated 30 degrees clockwise from the positive reference, the other end of the U-shaped guide seat 302 will abut against the other side wall of the limiting protrusion 507. When rotated clockwise, the end of the armrest cover 200 will face the passenger seat position, allowing the driver to straighten his arm, thereby improving the adaptability of the armrest cover 200.

[0031] It is worth mentioning that, according to Figure 6-11 As shown, the fixed frame 400 and the box 100 are detachable. A locking block 504 is provided at the bottom of the fixed shaft 502, and a slot 505 adapted to the locking block 504 is provided at the top of the protrusion 501. Both the locking block 504 and the slot 505 have rectangular cross-sections. The locking block 504 at the bottom of the fixed shaft 502 is inserted into the slot 505. The box body 100 is divided into a top cover and a shell. The top cover and the shell are hinged to achieve a flip-top structure. This structure is existing technology and will not be described in detail here. The protrusion 501 is fixed on the top cover. A through hole is opened at the part of the top cover that contacts the protrusion 501, and the through hole is connected to the slot 505. The slot 504 has a threaded hole inside that is connected to the fixed shaft 502. When it is necessary to connect the fixing frame 400 and the housing 100 together, the locking block 504 is inserted into the locking slot 505. At this time, the through hole at the locking slot 505 and the threaded hole of the locking block 504 can overlap. Then, the fixing bolt is inserted into the through hole from the bottom of the top cover and screwed in so that the fixing bolt is inserted into the threaded hole of the locking block 504, thereby fixing the fixing shaft 502 and the protrusion 501. At this time, the limiting block 503 at the top of the fixing shaft 502 can block the pin hole 301 of the connecting frame 300, so that the connecting frame 300 cannot be detached from the fixing shaft 502, thereby limiting and fixing the connecting frame 300 and the fixing frame 400, so that the fixing frame 400 is connected to the housing 100. When it is necessary to disassemble the fixed frame 400, tighten the fixing bolts to remove it from the threaded hole of the fixed shaft 502, so that the fixed shaft 502 and the protrusion 501 are separated from each other, so that the limiting block 503 can not limit the connecting frame 300, and thus the limitation on the fixed frame 400 can be removed, so that the sliding groove 402 at the bottom of the fixed frame 400 can be disengaged from the protrusion 501, thereby removing the fixed frame 400 from the housing 100 for easy maintenance later.

[0032] Furthermore, such as Figure 9 and 11 As shown, the armrest cover 200 and the fixing frame 400 are detachably connected. The fixing frame 400 has six inserts 403 inside. The six inserts 403 are grouped into three groups and are respectively set at the two edges of the fixing frame 400. The bottom surface of the armrest cover 200 has insert strips 201 corresponding to the inserts 403, and the insert strips 201 have threaded holes. The inserts 403 have through holes corresponding to the threaded holes, and the through holes extend to the bottom of the fixing frame 400. During installation, the handrail cover 200 and the fixing frame 400 are spliced ​​together, so that the insert strip 201 on the bottom surface of the handrail cover 200 is inserted into the insert block 403 on the upper part of the fixing frame 400. Then, the connecting bolt is inserted from the bottom of the fixing frame 400 and passes through the through hole of the insert block 403, and then screwed into the threaded hole of the insert strip 201 to achieve a fixed connection between the handrail cover 200 and the fixing frame 400. When disassembly is required, the connecting bolts are turned in the opposite direction to remove them from the threaded holes of the insert 201, thereby enabling the disassembly and separation of the handrail cover 200 and the fixed frame 400, facilitating the inspection and maintenance of the fixed frame 400 and the connecting bracket 300.

[0033] How to use this utility model: First, it should be clarified that this utility model is mainly used to realize the rotation function of the armrest cover 200 in the armrest box. It should be clarified here that the box body 100 is the armrest box in the prior art, and the box body 100 is composed of a shell and a flip-up top cover. Since this is not the innovation of this utility model, the structure will not be described in detail or limited here. Only the usage method and installation position of the armrest cover 200 will be described in detail. When it is necessary to rotate the armrest cover 200, first push the armrest cover 200 to slide, so that the armrest cover 200 drives the fixed frame 400 to slide in a straight line. At this time, the connecting frame 300 is in a relatively stationary state, while the fixed frame 400 slides along the length direction of the connecting frame 300 through the slide rail 401. Then, the armrest cover 200 is rotated, causing the fixed frame 400 to rotate synchronously. The fixed frame 400 drives the connecting frame 300 to rotate via the slide rail 401. The connecting frame 300 rotates around the axis of the fixed shaft 502, thereby causing the armrest cover 200 to rotate synchronously around the axis of the fixed shaft 502. If rotated 60 degrees counterclockwise, during the rotation, the positioning block 303 will disengage from the groove 506 due to the end face of the arc structure and move away from the limiting block 503. At this time, the limiting block 503 compresses the compression spring 304. When rotated 15 degrees until the positioning block 303 corresponds to the next adjacent groove 506, the rebound force of the compression spring 304 pushes the positioning block 303 to embed into the lower groove. Within an adjacent groove 506, the armrest cover 200 rotates 15 degrees to one position. Therefore, rotating it counterclockwise by 60 degrees results in four positions. When the armrest cover 200 rotates to four positions, the positioning block 303 will engage with the groove 506 adjacent to the limiting protrusion 507. At this time, one end of the guide seat 302 will abut against the side wall of the limiting protrusion 507, thus completing the angle adjustment. The function of adjusting the horizontal angle by rotating the armrest cover 200 allows the driver to adjust the tilt angle of the armrest cover 200 according to their own driving habits, so that the driver's arm is fully in contact with the support surface, thereby reducing fatigue and making long-distance driving more comfortable.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
