Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a bed frame. Background Art

[0002] The existing bed frame includes a bed frame and a backrest arranged at the front edge of the bed frame. The backrest is an integrated structure without a storage space, which makes it impossible to effectively utilize the space inside the backrest. As a result, the bed frame has no protruding private storage space, which affects the user experience. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides a bed frame having a backrest comprising a base and a cover, a storage cavity with a safe being provided in the base, and the cover being used to shield and hide the storage cavity, thereby ensuring that the backrest has a storage function and that the storage cavity has good privacy, thereby improving the user experience.

[0004] The present invention is realized in the following manner: a bed frame, comprising a bed body and a backrest arranged at the front edge of the bed body, the backrest comprising a base and a cover, the base being provided with a storage cavity open upward, the storage cavity being provided with a safe, the cover being rotatably mounted above the base so as to swing the cover between an open state in which the storage cavity is exposed and a closed state in which the storage cavity is blocked. A backrest comprising a base and a cover is provided, a storage cavity with a safe being provided in the base, the cover being swung between an open state and a closed state in which the storage cavity is blocked, the cover being used to shield and hide the storage cavity, thereby ensuring that the backrest has a storage function and provides storage space for the user, and also shielding the storage cavity with the cover to ensure that the storage space has good privacy, and also providing a private storage space with the safe, thereby improving the user experience.

[0005] Preferably, the backrest is provided with a locking assembly, and the cover is locked in place by the locking assembly when it swings to the closed position. The locking assembly can lock and position the cover when it is switched to the closed position, so that the cover can be securely positioned in the closed position, preventing the cover from exposing the safe due to force movement, and ensuring a good degree of privacy for the storage chamber.

[0006] Preferably, the clamping assembly includes a limiting cavity provided between the cover and the base, and a limiting post movably provided in the limiting cavity. The bottom wall of the limiting cavity forms a guide surface inclined along the width direction of the backrest, and the limiting post can slide back and forth between an unlocking position near the top edge of the guide surface and a locking position near the bottom edge of the guide surface. The limiting post can move back and forth between the unlocking position and the locking position in the limiting cavity. The limiting post can not only not clamp and position the cover when switching to the unlocking position, thereby facilitating the swinging of the cover between the closed state and the open state, but can also lock the cover in the closed state when switching to the locking position, thereby preventing the cover from accidentally opening due to force, preventing the accommodating cavity from being exposed due to being open, and improving privacy.

[0007] Preferably, the bottom surface of the cover is provided with an upper retaining groove that is exposed downward, and the top surface of the base is provided with a lower retaining groove that is exposed upward. When the cover is swung to the closed position, the upper and lower retaining grooves are vertically aligned and enclosed to form a retaining cavity for receiving the retaining post. The upper and lower retaining grooves are provided on the cover and base, respectively, which not only facilitates processing but also ensures that the cover and base can change their relative position relationship by respectively cooperating with the corresponding ends of the retaining post, facilitating operation and use.

[0008] Preferably, the limiting column is in a cubic shape, the guide surface is arranged along the length direction of the cross-sectional profile of the limiting column, and the width of the limiting cavity is the same as the thickness of the limiting column, so that the limiting column slides along the guide surface in a vertical position. The bottom surface of the limiting column is in contact with the guide surface, which not only ensures that the limiting column can move back and forth between the unlocking position and the locking position in a vertical position, but also reduces the resistance between the limiting column and the limiting column, ensuring that the limiting column can slide smoothly along the guide surface. The limiting cavity and the limiting column have the same front-to-back dimensions to prevent the limiting column from shaking back and forth in the limiting cavity.

[0009] Preferably, the guide surface is curved, and the vertical cross-section of the bottom surface of the limiting post along the width of the backrest is curved to increase the contact area between the bottom surface of the limiting post and the guide surface. The front-to-back projection of the bottom surface of the limiting post is curved to facilitate contact with the guide surface, thereby ensuring that the limiting post can reciprocate between the unlocking position and the locking position along the width of the backrest.

[0010] Preferably, the rear edge of the bottom surface of the cover is connected to the rear edge of the top surface of the base via a rotating shaft, and the bottom surface of the limit post is arc-shaped along the vertical cross-section in the front-to-back direction, so that when the limit post switches to the unlocking position, it can swing synchronously with the upper latching slot and avoid disengaging from the lower latching slot. The bottom of the limit post has an arc-shaped projection along the width direction of the backrest, thereby forming an avoidance area. When the limit post slides along the guide surface to the unlocking position and is lifted upward, the limit post can swing synchronously with the cover and pass through the avoidance area to avoid the notch of the lower latching slot, thereby facilitating the switch of the cover to the opening position.

[0011] Preferably, the cover is switched to a closed position and overlaps the top surface of the base. An unlocking channel is reserved between the cover and the top surface. The inner end of the unlocking channel communicates with the limit cavity, and the outer end is exposed to the side wall of the backrest. This allows the limit post to switch from the locked position to the unlocked position when pushed by an external tool passing through the unlocking channel. The unlocking channel allows an external tool to pass through and drive the limit post from the locked position to the unlocking position, which not only facilitates the user to open the cover, but also prevents the cover from being accidentally opened by concealing the unlocking channel, thereby enhancing privacy.

[0012] Preferably, the unlocking channel is positioned adjacent to the bottom edge of the guide surface, and an external tool pushes the retaining post along the width of the backrest to move it toward the unlocking position. The bottom edge of the guide surface represents the locking position for the retaining post. The bottom of the retaining post and the lower retaining slot both have a significant overlap height, preventing the retaining post from escaping the lower retaining slot through a clearance area. This ensures that the cover and base remain in a fixed relative position due to their simultaneous engagement by the retaining post. The unlocking channel is oriented in the same direction as the retaining post's movement when switching to the unlocking position, facilitating the unlocking operation.

[0013] Preferably, the vertical cross-sectional profile of the unlocking channel is flat to hide the external port of the unlocking channel, which not only facilitates the passage of external tools but also improves concealment by reducing the external port.

[0014] Preferably, the external tool is in the form of a long sheet, and the thickness of the external tool is smaller than the height of the unlocking channel, ensuring that the external tool can smoothly pass through the unlocking channel and push the limit column to switch to the unlocking position.

[0015] Preferably, the external tool is longer than the unlocking channel, so that when the external tool pushes the limit post, a grip portion is exposed at the external port. This external tool is long enough to traverse the unlocking channel and push the limit post, while also providing a grip for the user to facilitate insertion and removal.

[0016] Preferably, the limiting cavity is provided with a magnet on the side wall of the unlocking channel, and the limiting post is provided with a magnetic member on the side wall facing the unlocking channel. The magnet attracts the magnetic member and drives the limiting post to switch to the locking position, thereby positioning the cover in the closed state. The limiting post automatically moves to the locking position under the attraction of the magnet and the magnetic member, thereby ensuring that the limiting post can automatically return to the locking position and ensure that the cover is locked in the closed state, preventing the cover from being accidentally opened.

[0017] The beneficial effects of the present invention are as follows: a backrest including a base and a cover is provided, a storage cavity with a safe is provided in the base, the cover can be swung and switched between an open state and a closed state, and the cover is used to shield and hide the storage cavity, which ensures that the backrest has a storage function and provides storage space for the user, and the cover is used to shield the storage cavity to ensure that the storage space has good privacy, and the safe is used to provide private storage space, thereby improving the user experience.

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and 2 A bed frame shown includes a bed body 1 and a backrest arranged at the front edge of the bed body 1. The backrest includes a base 2 and a cover 3. The base 2 is provided with a storage cavity that is exposed upward. The storage cavity is provided with a safe 11. The cover 3 is rotatably mounted above the base 2 so that the cover 3 can swing between an open state in which the storage cavity is exposed and a closed state in which the storage cavity is covered. The backrest includes a base 2 and a cover 3. The base 2 is provided with a storage cavity with a safe. The cover 3 can swing between an open state and a closed state in which the storage cavity is covered. The cover 3 is used to shield and hide the storage cavity, ensuring that the backrest has a storage function and provides storage space for the user. The cover 3 also shields the storage cavity to ensure that the storage space has good privacy. The safe 11 is also used to provide a private storage space, improving the user experience.

[0025] In actual operation, the backrest is provided with a clamping component 4, and the cover 3 is swung to the covering state and is clamped in place by the clamping component 4, ensuring that the cover 3 can be clamped in place by the clamping component 4, preventing the risk of the safe 11 being exposed due to the cover 3 being opened due to force, ensuring that the accommodating cavity has good privacy, and improving the user experience.

[0026] In actual operation, the locking assembly 4 includes a limiting cavity provided between the cover 3 and the base 2, and a limiting post 5 movably provided in the limiting cavity. The bottom wall of the limiting cavity forms a guide surface 6 inclined along the width direction of the backrest. The limiting post 5 can slide back and forth between an unlocking position near the top edge of the guide surface 6 and a locking position near the bottom edge of the guide surface 6. The limiting post 5 is movably installed in the limiting cavity, which ensures that the limiting post 5 can switch between the unlocking position and the locking position, and also ensures that the limiting post 5 can be locked with the base 2 and the cover 3 at the unlocking position to prevent the cover 3 from switching to the open state. It also ensures that the limiting post 5 is only locked with the cover 3 in the locking position, facilitating the switch of the cover 3 to the open state.

[0027] In actual operation, the limiting cavity and the limiting post 5 have the same front-to-back dimensions. A movable space is provided within the limiting cavity along the width of the backrest. The bottom wall of the limiting cavity forms the guide surface 6. The limiting post 5 can contact the guide surface 6 and reciprocate along the width of the backrest, enabling the limiting post 5 to switch between an unlocking position at the first end of the limiting cavity and a locking position at the second end of the limiting cavity. An unlocking channel is provided on the sidewall of the backrest at the junction of the base 2 and the cover 3. The two end edges of the guiding surface 6 along the width of the backrest are a bottom edge and a top edge with a height difference, respectively. The bottom edge of the guiding surface 6 is located near the unlocking channel, while the top edge is located away from the unlocking channel.

[0028] After that, the user can lock the lid 3, and the lock lock 1 is locked, so that the user can lock the lid 3. When the user completes the operation of the safe 11 and needs to close the cover 3, first, the top of the limit post 5 is inserted into the first end of the upper slot 7, so that the limit post 5 is inserted to the bottom of the upper slot 7, and then the cover 3 is swung from the open state to the closed state. Since most of the limit post 5 is inserted in the upper slot 7, the bottom of the limit post 5 can avoid the notch of the lower slot 8 through the avoidance area and insert into the lower slot 8, ensuring that the cover 3 is smoothly switched to the closed state; then, the cover 3 is closed in place and drives the limit post 5 linked to it to flip over, so that the bottom surface of the limit post 5 can contact the top edge of the guide surface 6 at the bottom of the lower slot 8; finally, the magnet 9 and the magnetic attraction part 10 attract each other and drive the limit post 5 to move to the locking position of the second end of the limit cavity, and the limit post 5 slides along the bottom edge of the guide surface 6 and lowers its height, so that the depth of the bottom of the limit post 5 inserted into the lower slot 8 increases. After being assembled, the magnet 9 and the magnetic attraction member 10 adhere to each other and ensure that the limit post 5 is positioned in the locked position. The top and bottom of the limit post 5 are respectively inserted into the upper slot 7 and the lower slot 8. The top of the limit post 5 and the upper slot 7, and the bottom of the limit post 5 and the lower slot 8 can only be inserted and removed vertically, and cannot be deflected relative to the rotation axis. This ensures that the cover 3 cannot be rotated out of the closed state, thereby effectively preventing the accommodating cavity from being exposed due to the opening of the cover 3. After the cover 3 is closed and locked, the cover 3 and the base 2 enclose a unlocking channel to facilitate the opening of the cover 3.

[0029] When the user needs to operate the safe 11 by opening the cover 3, first, insert the external tool into the unlocking channel and push the limit column 5 from the locking position to the unlocking position. During the movement, the limit column 5 will complete the lifting displacement driven by the guide surface 6; then, the cover 3 switches from the closed state to the open state with the rotating shaft as the center, the top of the limit column 5 is inserted into the upper slot 7 and swings synchronously with the cover 3, and the bottom of the limit column 5 avoids the groove wall and notch of the lower slot 8 through the avoidance area, so that the limit column 5 is disengaged from the lower slot 8 and can swing synchronously with the cover 3, thereby realizing the opening operation of the cover 3.

[0030] The above operation realizes closing, locking and unlocking of the cover 3, which effectively simplifies the structure, facilitates manual operation and does not require external power support. It also improves confidentiality by hiding the unlocking channel, and uses the magnet 9 and the magnetic attraction part 10 to facilitate automatic locking, thereby improving operational convenience.

[0031] In actual operation, the limiting post 5 is cubical in shape, with the guide surface 6 extending along the length of the limiting post 5's cross-sectional profile. The width of the limiting cavity is the same as the thickness of the limiting post 5, allowing the limiting post 5 to slide along the guide surface 6 in an upright position. The bottom surface of the cover 3 is provided with an upper retaining groove 7, which is exposed downward, and the top surface of the base 2 is provided with a lower retaining groove 8, which is exposed upward. When the cover 3 is swung to the closed position, the upper retaining groove 7 and the lower retaining groove 8 are vertically aligned and enclosed to form a retaining cavity for the limiting post 5. The upper retaining groove 7 and the lower retaining groove 8, respectively provided on the cover 3 and the base 2, not only limit the limiting post 5 to prevent it from detaching, but also secure the relative position between the cover 3 and the base 2 by engaging with the top and bottom of the limiting post 5, ensuring locking reliability. Furthermore, the upper retaining groove 7 can be used to drive the limiting post 5 in the unlocking position to swing synchronously, ensuring that the limiting post 5 can detach from the lower retaining groove 8.

[0032] In actual operation, the guide surface 6 is set at an angle, and the guide surface 6 contacts the bottom surface of the limit column 5. The guide surface 6 can convert the horizontal force acting on the limit column 5 into a vertical force that drives it to rise. Specifically, the limit column 5 located at the unlocking position at the top edge of the guide surface 6 can move to the locking position at the bottom edge of the guide surface 6 under the action of magnetic attraction. The depth of the limit column 5 inserted into the lower card slot 8 increases, so that the limit column 5 cannot avoid the lower card slot 8 through the avoidance area, thereby playing a carding and positioning role for the base 2 and the cover 3.

[0033] In actual operation, the bottom surface of the limiting column 5 has a double-arc structure, including a first arc surface that can be aligned with the guide surface 6 and is arranged along the width direction of the backrest, and a second arc surface that can avoid the lower clamping groove 8 and is arranged along the front-to-back direction. Specifically, the guide surface 6 is an arc surface, and the vertical cross-section of the bottom surface of the limiting column 5 along the width direction of the backrest is an arc and forms the first arc surface (such as Figure 4 As shown), to increase the contact area between the bottom surface of the limiting column 5 and the guide surface 6; the rear edge of the bottom surface of the cover 3 is connected to the rear edge of the top surface of the base 2 by a rotating shaft, and the bottom surface of the limiting column 5 along the vertical cross-section in the front-to-back direction is arc-shaped and forms a second arc surface (as shown Figure 3 As shown), the second arc-shaped surface is used to form an avoidance area so that when the limit column 5 switches to the unlocking position, it can swing synchronously with the upper card slot 7 and avoid disengaging from the lower card slot 8.

[0034] In actual operation, the cover 3 is switched to a closed position and overlaps the top surface of the base 2. An unlocking channel is reserved between the cover 3 and the top surface. The inner end of the unlocking channel communicates with the limit cavity, and the outer end is exposed to the side wall of the backrest. This allows the limit post 5 to switch from the locked position to the unlocked position when pushed by an external tool passing through the unlocking channel. The unlocking channel is located adjacent to the bottom edge of the guide surface 6. The external tool pushes the limit post 5 along the width of the backrest to move it to the unlocking position, facilitating the opening of the cover 3.

[0035] In practice, the unlocking channel has a flat vertical cross-section. By reducing the size of the external port, the unlocking channel is concealed, preventing others from finding the unlocking channel and opening the cover 3, thereby enhancing privacy and confidentiality. The external tool is in the form of a long sheet, with a thickness less than the height of the unlocking channel and a length greater than the length of the unlocking channel. This allows the external tool to push the limit post 5 with a grip exposed at the external port. The user grasps the grip and inserts the external tool into the unlocking channel, facilitating the unlocking of the locking assembly 4.

[0036] In actual operation, the limiting cavity is provided with a magnet 9 on the side wall of the unlocking channel, and the limiting post 5 is provided with a magnetic attraction member 10 on the side wall facing the unlocking channel. The magnet attracts the magnetic attraction member 10 and drives the limiting post 5 to switch to the locking position, so that the cover 3 is positioned in the closed state. The magnet 9 is arranged on the end wall of the first end of the limiting cavity. By attracting the magnetic attraction member 10, the limiting post 5 is guided to slide along the guide surface 6 to the locking position, ensuring that the limiting post 5 is always in the locking position, thereby ensuring that the cover 3 is always locked in the closed state.
