Description

Technical Field

[0001] This invention relates to the field of medical vehicle technology, and specifically to a double-layer platform medical vehicle. Background Technology

[0002] A medical cart is a mobile device used in medical institutions to carry, transport, and temporarily store medical equipment, medicines, consumables, and other supplies. It is typically designed as a trolley and equipped with multi-layered shelves, drawers, hooks, or a tabletop. Its core function is to provide medical staff with a convenient platform for storing and handling supplies at the bedside, in operating rooms, and emergency rooms. It is widely used in medical procedures such as dressing changes, emergency care, surgical assistance, and nursing. By optimizing spatial layout and mobility, medical carts can significantly improve medical efficiency, reduce time spent retrieving supplies, and lower the risk of cross-infection.

[0003] Traditional medical carts often use a single-layer fixed platform or a simple layered storage structure. While these can meet basic needs, the limited space on a single-layer platform makes it impossible to simultaneously place multiple instruments (such as medication supplies, monitoring equipment, and emergency medicines). Frequent item changes are required during operation, affecting treatment efficiency. Fixed layered designs are difficult to adjust flexibly according to mission requirements, and the accumulation of instruments can lead to confusion in retrieval, potentially delaying treatment, especially in emergencies. In addition, large single-layer platform medical carts take up a lot of space, making them difficult to move in narrow wards or operating rooms, and they cannot be folded and stored, wasting storage space when not in use.

[0004] Therefore, there is an urgent need for a double-layer medical cart that can not only save space when folded by using a double-layer design, but also provide twice the effective operating area when unfolded to meet the needs of multi-tasking. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to address the shortcomings of existing technologies by providing a double-layer medical cart with a sliding mechanism that enables the folding and quick unfolding of the cart, adapting to space constraints in different scenarios, such as folding for use in small wards and fully unfolding in operating rooms.

[0006] Technical Solution: The present invention discloses a double-layer medical cart comprising a cart body and a platform. The platform is mounted on the top of the cart body and includes a first platform and a second platform. The cart body serves as a supporting frame, with a sliding rail and a folding mechanism on its top. When folded, the first platform is located at the top of the cart body; when unfolded, it slides to the left to its leftmost position. When folded, the second platform is stored in the gap between the first platform and the cart body via the folding mechanism; when unfolded, it slides to the right to its rightmost position. Folded State: The first platform remains horizontal, covering the second platform as the upper operating surface. The folding mechanism slides the second platform inward, completely embedding it into the gap between the first platform and the top surface of the cart body, forming an upper and lower stacked structure. In this state, the double-layered platforms are vertically stacked, facilitating movement and storage in confined spaces. Unfolded state: The first platform slides to the left along the top of the vehicle body to the left limit position via a slider and folding mechanism, and is locked in place. The second platform moves out of the gap via a slider and folding mechanism, slides to the right along the slide rail to the right limit position, and is unfolded to be on the same horizontal plane as the first platform. At this time, the two platforms are unfolded to form a continuous large-area operating platform, which can be used to place multiple medical devices or medicines at the same time.

[0007] Furthermore, the folding mechanism includes two Y-shaped slides symmetrically fixed at the front and rear positions of the top of the vehicle body. Each Y-shaped slide includes a support surface located on the outer side, with an upper slide and a lower slide opening towards the inside on the support surface. A first elastic positioning bead is provided in the upper slide, and a second elastic positioning bead is provided in the lower slide. Limiting grooves corresponding to the first and second elastic positioning beads are also provided inside the upper and lower slides, respectively.

[0008] The core of the folding mechanism in this invention is a symmetrically arranged Y-shaped slide, fixed to the front and rear sides of the top of the vehicle body. Shaped like the letter "Y," it consists of an upper slide and a lower slide branching out. Both slide openings face inwards towards the vehicle body. The support surface is located outside the Y-shaped slide, supporting the platform slide bar and guiding the sliding direction. A first elastic positioning bead is embedded in the upper slide bar, cooperating with the slide bar of the first platform to lock the unfolded or folded state. A second elastic positioning bead is embedded in the lower slide bar, cooperating with the slide bar of the second platform to control the folding and unfolding of the lower platform. Limiting grooves are located in the upper and lower slide bars, matching the elastic positioning beads to provide locking positions. The Y-shaped slide guides the second platform from the lower slide to the upper slide through a branching structure, ultimately allowing both platforms to share the same slide to complete planar expansion.

[0009] Furthermore, the Y-shaped slide is divided into an upper slide and a lower slide by a partition. The upper slide has openings at both ends, and the lower slide has a ramp at the right end, which extends to the top surface.

[0010] Furthermore, the bottom surfaces of the first and second platforms are provided with sliding strip devices corresponding to the first and second Y-shaped slides, and the sliding strip devices drive the first and second platforms to slide within the slides of the first and second Y-shaped slides.

[0011] Furthermore, the slider device includes a first pair of sliders disposed on the bottom surface of the first plate and a second pair of sliders disposed on the bottom surface of the second plate. The first pair of sliders and the second pair of sliders are inserted into corresponding Y-shaped slides and slide within the Y-shaped slides.

[0012] Furthermore, the bottom of the vehicle body is equipped with casters, which are omnidirectional wheels with a locking function.

[0013] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows:

[0014] (1) The design of the double-layer platform medical vehicle of the present invention integrates key technologies of mechanical slide rail, elastic positioning and linkage structure, which solves the contradiction between static space allocation and limited load-bearing capacity of traditional medical vehicles; wherein the mechanical slide rail is a combination of slide bar and Y-shaped slide, the elastic positioning is elastic positioning bead, and the linkage structure is a combination structure of slide bar, Y-shaped slide and elastic positioning bead linkage.

[0015] (2) The present invention achieves smooth transition and precise locking of the platform by combining the Y-shaped slide and the elastic positioning bead, avoiding repeated manual adjustment; medical staff only need to push and pull to complete the unfolding and storage of the platform, which is intuitive and labor-saving and meets the high efficiency requirements of medical scenarios.

Detailed Implementation

[0041] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.

[0042] like Figure 1 The illustrated double-layer medical cart includes a vehicle body 1 and a platform 2. The platform 2 is mounted on the top of the vehicle body 1 and includes a first platform 201 and a second platform 202. The first platform 201 and the second platform 202 are connected by a folding structure 3. The bottom of the vehicle body 1 has casters 4, which are omnidirectional wheels with locking function.

[0043] The folding mechanism 3 includes a first Y-shaped slide rail 301 and a second Y-shaped slide rail 307 symmetrically fixed at the front and rear positions of the top of the vehicle body 1. The first Y-shaped slide rail 301 and the second Y-shaped slide rail 307 have the same structure, such as... Figure 2 As shown, both include a support surface on the outer side, with an upper slide rail 302 and a lower slide rail 303 opening inwards on the support surface. The Y-shaped slide rail 301 is divided into the upper slide rail 302 and the lower slide rail 303 by a partition 308. The left and right ends of the upper slide rail 302 are open, and the right end of the lower slide rail 303 is provided with a ramp 306, which extends to the top surface 309. A first elastic positioning bead 304 is provided in the upper slide rail 302, and a second elastic positioning bead 305 is provided in the lower slide rail 303. Limiting grooves corresponding to the first elastic positioning bead 304 and the second elastic positioning bead 305 are also provided inside the upper slide rail 302 and the lower slide rail 303, respectively. The bottom surfaces of the first platform 201 and the second platform 202 are provided with slide bar devices corresponding to the first Y-shaped slide rail 301 and the second Y-shaped slide rail 302. The slide bar devices include a first slide bar pair 203 disposed on the bottom surface of the first platform 201 and a second slide bar pair 204 disposed on the bottom surface of the second platform 202. The first slide bar pair 203 drives the first platform 201 to slide within the slide rail of the first Y-shaped slide rail 301, and the second slide bar pair 204 drives the second platform 202 to slide within the slide rail of the second Y-shaped slide rail 307.

[0044] This embodiment can be folded or unfolded, as detailed below:

[0045] I. The initial state is the fully folded state, such as Figures 3-6 As shown:

[0046] The first platform 201 is located on the upper layer: horizontally covering the top of the vehicle body 1, with the first sliding bar pair 203 embedded in the rightmost side of the upper sliding track 302 of the first Y-shaped sliding track 301 and the second Y-shaped sliding track 307. Locking: the first elastic positioning bead 304 is embedded in the limiting groove of the sliding bar pair 203 to fix the platform position. The second platform 202 is located on the lower layer, vertically stored in the gap between the vehicle body 1 and the first platform 201, with the second sliding bar pair 204 embedded in the leftmost side of the lower sliding track 303 of the first Y-shaped sliding track 301 and the second Y-shaped sliding track 307. Locking: the second elastic positioning bead 305 is embedded in the limiting groove of the sliding bar pair 204 to prevent slippage. Overall state: the two-layer platform is vertically stacked, resulting in a compact vehicle body height, facilitating movement and storage. The casters 4 are in the unlocked state and can be freely pushed.

[0047] II. Unfolding process:

[0048] Step 1: Unlock and unfold the first panel 201 (slide to the left), as shown. Figures 7-12 As shown:

[0049] Pulling the first platform 201 to the left requires a force that overcomes the spring resistance of the first elastic positioning bead 304. The first slide bar pair 2033 slides to the left along the upper slide rail 302. The first elastic positioning bead 304 is squeezed back into the inner wall of the slide rail by the edge of the slide bar, disengaging from the limiting groove. The first slide bar pair 203 slides to the left limit position of the upper slide rail 302. At this time, the first elastic positioning bead 304 is embedded in the left groove of the slide bar pair 203, locking the platform. At this time, the first platform 201 is horizontally unfolded to the left side of the top surface of the vehicle body 1, forming the left operating platform.

[0050] Step 2: Unlock and unfold the second panel 202 (slide it to the right and lift it up), as shown. Figures 7-12 As shown:

[0051] Pull the second platform 202 to the right to overcome the resistance of the second elastic positioning bead 305. The second slider pair 204 slides to the right along the lower slide rail 303, the second elastic positioning bead 305 disengages from the groove, and the slider moves freely; when the second slider pair 204 reaches the right end of the lower slide rail 303, it is lifted upward along the ramp 306, and the front end of the slider enters the opening at the right end of the upper slide rail 302; continue to pull the second platform 202 to the right, the second slider pair 204 moves to the right limit position along the upper slide rail 302, at this time, the second platform 202 is horizontally unfolded to the right side of the top surface of the vehicle body 1, and is on the same plane as the first platform 201.

[0052] Step 3: Align and lock the two platforms.

[0053] Slightly push the second platform 202 to the left to align the edges of the two platforms. The second slide bar pair 204 slides to the left along the upper slide rail 302 until it aligns with the first platform 201. The first elastic positioning bead 304 embeds into the middle groove of the second slide bar pair 204, completing the joint locking of the two platforms. At this point, the two platforms form a continuous plane, doubling the total area to meet the needs of large-scale medical operations. The omnidirectional wheel 4 switches to the locked state to ensure vehicle stability.

[0054] III. Folding Process

[0055] Step 1: Unlock and fold the second board 202 (slide it to the right and move it down).

[0056] Gently push the second platform 202 to the right, overcoming the resistance of the first elastic positioning bead 304, causing its second slide bar pair 204 to disengage from the middle groove. The second slide bar pair 204 moves to the right extreme position along the upper slide rail 302, and the first elastic positioning bead 304 embeds into the right groove. Continue pushing the second platform 202 to the right, and the slide bar pair 204 slides down the ramp 306 to the right end of the lower slide rail 303. Push the second platform 202 to the left, and the slide bar pair 204 moves to the leftmost left position along the lower slide rail 303, and the second elastic positioning bead 305 embeds into the groove, locking the position. At this time, the second platform 202 is vertically stored in the gap between the vehicle body 1 and the first platform 201.

[0057] Step 2: Fold the first panel 201 (slide it to the right).

[0058] Pushing the first platform 201 to the right overcomes the resistance of the first elastic positioning bead 304, and the slider pair 203 moves to the far right along the upper slide rail 302. The first elastic positioning bead 304 then embeds into the right-side groove, locking the platform. At this point, the first platform 201 covers the second platform 202, the double-layered platforms are stacked vertically again, the vehicle body returns to its compact shape, the casters 4 are unlocked, and the vehicle body can move freely.

[0059] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
