Description

Technical Field

[0001] This utility model belongs to the field of body transport technology, specifically relating to a walking chassis structure for a body transport device. Background Technology

[0002] The funeral industry involves the handling of remains, which takes place in various settings. For those who die in hospitals, the body can be transported via elevator. However, for those who die in residential buildings, especially high-rise buildings, although elevators are available, other residents may be reluctant to use them to transport the body. Therefore, the body must be carried down the stairs.

[0003] CN202210357004.X discloses a body transport device, which has a powered track installed below a support plate for placing the body via a first lifting mechanism, and a resistance track installed in front of the powered track via a second lifting mechanism. A powered wheel capable of walking on the ground is provided at the front end of the support plate, and a swivel wheel with an operating surface rotatable relative to the powered track is connected to the front end of the powered track. Combined with its… Figure 1 As shown in Figure 11, when turning from the staircase to the landing platform (staircase turning platform), the support plate tilts, the resistance track retracts upward and does not contact the ground, and the front drive wheel touches the ground and moves on the ground. At the same time, the swivel wheel at the front of the resistance track extends and contacts the ground, supported by the drive wheel and the swivel wheel. However, this structure results in a large turning radius for the body transport device, and a large portion of the rear end of the drive track extends beyond the support plate, making the front and rear dimensions large when tilted. When the size of the staircase landing platform is small, due to its large size and large turning radius, it cannot turn on its own and requires manual lifting of the support plate to turn, which is inconvenient. Moreover, the use of two sets of tracks, resistance track and drive track, makes the overall structure relatively bulky and not lightweight enough. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art. The purpose of the present invention is to provide a walking chassis structure for a body transport device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a walking chassis structure for a body transport device, the body transport device including a stretcher and a walking chassis structure supporting the stretcher, the walking chassis structure including a powered track capable of running on the ground and stairs, and a support frame mounted on the powered track, the stretcher being mounted on the top of the support frame; the support frame is a linkage mechanism connecting the powered track and the stretcher, the linkage mechanism being connected to a tilting drive mechanism that drives the stretcher to move horizontally or tilt forward.

[0006] The above-mentioned technical solution relies on powered tracks to descend stairs, turn on staircase platforms, and travel on flat ground. Compared with existing technologies that use two sets of tracks (powered tracks and resistance tracks), this utility model only uses one set of tracks, resulting in a simple and lightweight structure. Furthermore, relying on powered tracks for turning allows for a smaller turning radius compared to existing technologies that use power wheels and swivel wheels. Moreover, because only one set of powered tracks is used, the front-to-back dimensions of the body transport device are smaller when the stretcher is tilted forward, which is beneficial for the operation of the body transport device in confined spaces such as staircase platforms.

[0007] In a preferred embodiment of this utility model, the linkage mechanism includes a telescopic main rod that tilts from bottom to top and from front to back, an upper connecting rod whose lower end rotates with the telescopic main rod, and a lower connecting rod whose upper end rotates with the upper connecting rod. The lower end of the telescopic main rod is rotatably connected to the powered track, the upper end of the telescopic main rod is rotatably connected to the stretcher, the upper end of the upper connecting rod is rotatably connected to the stretcher, and the lower end of the lower connecting rod is connected to the powered track. The telescopic main rod is driven to extend and retract by a tilting drive mechanism, the lower connecting rod does not move, and the upper connecting rod can move together with the telescopic main rod to make the stretcher horizontal or tilted forward.

[0008] In the above technical solution, when adjusting the forward tilt angle of the stretcher, the lower connecting rod does not move, but plays a supporting role to improve the stability of the stretcher. The upper connecting rod moves by extending and retracting the telescopic main rod. The telescopic main rod and the upper connecting rod drive the stretcher to move, thereby adjusting the forward tilt angle of the stretcher. The structure is simple and the operation is reliable.

[0009] In a preferred embodiment of this utility model, two telescopic main rods are symmetrically arranged along the width direction of the stretcher. Each of the two telescopic main rods is connected to an upper connecting rod, and each of the two upper connecting rods is connected to a lower connecting rod. The two telescopic main rods extend and retract synchronously.

[0010] The above technical solution uses two sets of linkage mechanisms symmetrically arranged along the width of the stretcher to improve the support strength of the stretcher.

[0011] In a preferred embodiment of this utility model, the telescopic main rod includes a lower main rod whose lower end is rotatably connected to the power track, and an upper main rod whose upper end is rotatably connected to the stretcher and can slide relative to the lower main rod. The upper connecting rod is rotatably connected to the lower main rod of the telescopic main rod. The upper main rod is driven to extend upward by a tilting drive mechanism, which increases the angle of the stretcher tilting forward. The upper main rod is driven to retract downward by a tilting drive mechanism, which decreases the angle of the stretcher tilting forward.

[0012] In the above technical solution, when the upper main pole extends upward, the angle of the stretcher tilting forward increases; when the upper main pole retracts downward, the angle of the stretcher tilting forward decreases, resulting in stable operation.

[0013] In a preferred embodiment of this utility model, a connecting rod is fixedly connected to the upper main rod of the telescopic main rod, and the tilting drive mechanism is a first telescopic cylinder connected to the connecting rod and installed on the lower main rod. The first telescopic cylinder drives the upper main rod to slide relative to the lower main rod, thereby causing the telescopic main rod to extend or retract.

[0014] In the above technical solution, the first telescopic cylinder is connected to the connecting rod fixed on the upper main rod. The telescopic main rod is extended or retracted by driving the connecting rod. When two telescopic main rods are set, both telescopic main rods are driven by the same first telescopic cylinder, resulting in good synchronization.

[0015] In a preferred embodiment of this utility model, the lower main rod adopts a slide rail structure with a groove, and the upper main rod is fixed with a slider that cooperates with the groove and can slide on the lower main rod.

[0016] The above technical solution uses a slider and a groove to guide the extension and retraction of the upper main rod, making its movement smoother.

[0017] In a preferred embodiment of this utility model, the lower connecting rod includes an upper rod portion whose upper end is rotatably connected to the upper connecting rod, and a lower rod portion whose lower end is rotatably connected to the power track via a sixth rotating shaft. The lower end of the upper rod portion is rotatably connected to the upper end of the lower rod portion, and the lower rod portion is connected to a folding drive mechanism that drives it to rotate around the sixth rotating shaft to unfold or retract the lower connecting rod. When the lower connecting rod is retracted, the angle between the lower rod portion and the upper rod portion decreases; when the lower connecting rod is unfolded, the angle between the lower rod portion and the upper rod portion increases.

[0018] The aforementioned technical solution divides the lower connecting rod into two parts: an upper rod and a lower rod. A folding drive mechanism allows the lower connecting rod to unfold or retract. When using this body transport device to transport a body, unfolding the lower connecting rod adjusts the stretcher to a horizontal or forward-tilted position. The lower connecting rod supports the stretcher via the upper connecting rod and the telescopic main rod, improving its stability. When the body transport device is not in use, it is folded down. By retracting the lower connecting rod, the device can be folded up, reducing its height and size for easier carrying and storage. Furthermore, simultaneously engaging both the folding and tilting drive mechanisms allows for stretcher height adjustment, enhancing practicality.

[0019] In another preferred embodiment of this utility model, the folding drive mechanism includes a second telescopic cylinder, one end of which is rotatably connected to the lower rod portion, and the other end of which is rotatably connected to the power track. By extending the telescopic shaft of the second telescopic cylinder, the angle between the lower rod portion and the upper rod portion decreases; by shortening the telescopic shaft of the second telescopic cylinder, the angle between the lower rod portion and the upper rod portion increases.

[0020] The above technical solution uses a second telescopic cylinder as the folding drive mechanism. The two ends of the second telescopic cylinder are rotatably connected to the lower rod and the power track, respectively. Thus, by extending and retracting the second telescopic cylinder, the lower connecting rod can be extended / retracted to extend / retract the body transfer device. The structure is simple and the operation is reliable.

[0021] In another preferred embodiment of this utility model, two powered tracks are spaced apart along the width direction of the stretcher. The powered tracks are provided with a load-bearing shell. A connecting plate is fixed between the load-bearing shells of the two powered tracks. The lower end of the support frame is connected to the load-bearing shell. And / or the powered track includes a front flat section in contact with the ground and an upwardly inclined rear section located behind the front flat section.

[0022] The above technical solution allows the load-bearing outer shell to protect the tracks and also serve as a support frame and stretcher for the load-bearing mechanism. A connecting plate is installed between the load-bearing outer shells of the two powered tracks, resulting in better overall integrity. The rear-tilted section, compared to a completely flat section, reduces the footprint of the new track structure. When the stretcher is used with the support frame tilted forward, the overall volume is smaller, which is beneficial for the operation of the body transport device in narrow spaces such as stair platforms.

[0023] In another preferred embodiment of the present invention, the bottom of the stretcher has a slide rail extending along its length, and an adjusting slider is provided at the connection between the support frame and the stretcher. The adjusting slider is slidably connected to the slide rail and fixed by fasteners.

[0024] The above technical solution, by setting up slide rails and adjusting sliders, can adjust the range of forward tilt angles of the stretcher by changing the distance between the adjusting sliders, thus meeting different needs and improving practicality; by adjusting the sliders to adjust the front and rear positions of the stretcher relative to the powered track, when the stretcher is unfolded to its maximum forward tilt angle, the front end of the stretcher is close to the front end of the powered track, making the structure of the body transport device more compact in the bent state.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0035] This utility model provides a walking chassis structure for a body transport device, such as... Figure 1 As shown, the body transport device includes a stretcher 30 for carrying the body and a chassis structure supporting the stretcher 30. The chassis structure includes powered tracks 10 capable of running on the ground and stairs, and a support frame 20 mounted on the powered tracks 10. The stretcher 30 is mounted on top of the support frame 20, and the powered tracks 10 support the stretcher 30 via the support frame 20. Two powered tracks 10 are spaced apart along the width of the stretcher 30. Each powered track 10 has a load-bearing outer shell 11, and a connecting plate 12 is fixed between the load-bearing outer shells 11 of the two powered tracks 10. The lower end of the support frame 20 is connected to the load-bearing outer shell 11. The support frame 20 includes a linkage mechanism connecting the powered tracks 10 and the stretcher 30, and the linkage mechanism is connected to a tilting drive mechanism 24 that drives its movement to make the stretcher 30 horizontal or tilt forward.

[0036] like Figure 1 and Figure 2 As shown, when the body transport device is operating on the ground, the linkage mechanism is fully deployed and the stretcher 30 is in a horizontal position; as Figure 3 As shown, when the body transport device is running on a staircase or staircase turning platform, the stretcher 30 tilts forward to put the body transport device in a bent state.

[0037] This technical solution, employing only a powered track 10, allows for easy descent of stairs, turning on stair landings, and travel on flat ground. The structure is simple, lightweight, and has a small turning radius. The invention utilizes a linkage mechanism to allow the stretcher 30 to tilt forward, accommodating various scenarios. For example, the stretcher 30 remains horizontal on the ground, but tilts forward when descending stairs or on stair landings. Especially in narrow stair landings, increasing the forward tilt angle of the stretcher 30 allows for a larger bending angle, reducing the front-to-back dimensions of the body transport device and minimizing its overall size. This enables smooth, autonomous turning on narrow stair landings without manual assistance.

[0038] like Figures 1-3As shown, in this utility model, the linkage mechanism includes a telescopic main rod 21 that tilts from bottom to top and from front to back, an upper connecting rod 22 whose lower end is rotatably connected to the telescopic main rod 21 via a first rotating shaft 41, and a lower connecting rod 23 whose upper end is rotatably connected to the upper connecting rod 22 via a second rotating shaft 42. The lower end of the telescopic main rod 21 is rotatably connected to the load-bearing shell 11 of the powered track 10 via a third rotating shaft 43 (specifically, a support seat can be installed on the load-bearing shell 11, and the third rotating shaft 43 is rotatably installed in the support seat). The upper end of the telescopic main rod 21 is rotatably connected to the stretcher 30 via a fourth rotating shaft 44. The upper end of the upper connecting rod 22 is rotatably connected to the stretcher 30 via a fifth rotating shaft 45. The lower end of the lower connecting rod 23 is connected to the load-bearing shell 11 of the powered track 10. When the linkage mechanism is fully extended, the upper connecting rod 22 tilts from bottom to top and from back to front, and the lower connecting rod 23 supports the upper connecting rod 22 from bottom to top and from back to front.

[0039] The telescopic main rod 21 is extended or retracted by the tilting drive mechanism 24, while the lower connecting rod 23 remains stationary (at this time, the lower connecting rod 23 provides support and maintains the stability of the linkage mechanism). The upper connecting rod 22 can move together with the telescopic main rod 21 to make the stretcher 30 horizontal or tilt forward. Specifically, as shown... Figure 2 and Figure 3 As shown, for example, when the angle of forward tilt of the stretcher 30 is increased by extending the telescopic main rod 21, the position of the second pivot 42 is fixed under the support of the lower connecting rod 23. The telescopic main rod 21 causes the upper connecting rod 22 to rotate counterclockwise around the second pivot 42. The lower end of the upper connecting rod 22 causes the lower end of the telescopic main rod 21 to rotate counterclockwise around the third pivot 43. The upper ends of the upper connecting rod 22 and the upper ends of the telescopic main rod 21 cause the stretcher 30 to rotate counterclockwise around the fourth pivot 44. As the angle of forward tilt of the stretcher 30 increases, the angle between the stretcher 30 and the telescopic main rod 21 gradually decreases until the stretcher 30 and the telescopic main rod 21 are nearly parallel, at which point the stretcher 30 can no longer tilt forward.

[0040] Preferably, two telescopic main rods 21 are symmetrically arranged along the width direction of the stretcher 30. Each of the two telescopic main rods 21 is connected to an upper connecting rod 22, and each of the two upper connecting rods 22 is connected to a lower connecting rod 23. The two telescopic main rods 21 extend and retract synchronously.

[0041] like Figures 1-3 As shown, in this utility model, the telescopic main rod 21 includes a lower main rod 211 whose lower end is rotatably connected to the power track 10, and an upper main rod 212 whose upper end is rotatably connected to the stretcher 30 and can slide relative to the lower main rod 211. The upper connecting rod 22 is rotatably connected to the lower main rod 211 of the telescopic main rod 21. The upper main rod 212 is driven to extend upward by the tilting drive mechanism 24, and the angle of forward tilt of the stretcher 30 increases under the transmission action of the upper connecting rod 22. The upper main rod 212 is driven to retract downward by the tilting drive mechanism 24, and the angle of forward tilt of the stretcher 30 decreases under the transmission action of the lower connecting rod 23.

[0042] Among them, a connecting rod 213 extending along the width direction of the stretcher 30 is fixedly connected to the upper main rod 212 of the telescopic main rod 21. The two ends of the connecting rod 213 are respectively fixedly connected to the upper main rod 212 of the two telescopic main rods 21. The tilting drive mechanism 24 is a first telescopic cylinder (such as an electric push rod) connected to the connecting rod 213 and installed on the lower main rod 211. Specifically, the first telescopic cylinder 24 can be installed by setting a mounting bracket 216 fixed to the lower main rod 211. The first telescopic cylinder 24 drives the upper main rod 212 to slide relative to the lower main rod 211, so that the telescopic main rod 21 can extend and retract.

[0043] like Figure 1 As shown, preferably, the lower main rod 211 adopts a slide rail structure with a groove 214, and a slider 215 that cooperates with the groove 214 and can slide on the lower main rod 211 is fixedly connected to the upper main rod 212. The slider 215 and the groove 214 guide the extension and retraction of the upper main rod 212, making its movement smoother. More preferably, the lower end of the first telescopic cylinder 24 is hinged to the mounting bracket 216, and the upper end of the first telescopic cylinder 24 is hinged to the connecting rod 213. Thus, when the extension and retraction of the upper main rod 212 is not parallel to the lower main rod 211 due to processing errors of various components, the swing of the first telescopic cylinder 24 can be used to adapt.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, in another preferred embodiment, the lower connecting rod 23 includes an upper rod portion 231 whose upper end is rotatably connected to the upper connecting rod 22 via a second rotating shaft 42, and a lower rod portion 232 whose lower end is rotatably connected to the load-bearing housing 11 of the power track 10 via a sixth rotating shaft 46. The lower end of the upper rod portion 231 and the upper end of the lower rod portion 232 are rotatably connected via a seventh rotating shaft 47. The lower rod portion 232 is connected to a folding drive mechanism 25 that drives its rotation to unfold or retract the lower connecting rod 23.

[0045] like Figure 3 and Figure 4 As shown, link 23 is currently... Figure 3 The unfolded state shown is collapsed to Figure 4 In the retracted state shown, the retracting drive mechanism 25 drives the lower rod 232 to rotate clockwise around the sixth pivot 46, and the lower rod 232 causes the upper rod 231 to rotate counterclockwise around the seventh pivot 47, thereby reducing the angle between the lower rod 232 and the upper rod 231. The retraction of the lower connecting rod 23 causes the upper connecting rod 22, the telescopic main rod 21, and the stretcher 30 to tilt forward at a reduced angle and gradually retract horizontally; when the lower connecting rod 23... Figure 4 The collapsed state shown is expanded to Figure 3In the unfolded state shown, the folding drive mechanism 25 drives the lower rod 232 to rotate counterclockwise around the sixth pivot 46, and the lower rod 232 causes the upper rod 231 to rotate clockwise around the seventh pivot 47, so that the included angle between the lower rod 232 and the upper rod 231 increases. The unfolding of the lower connecting rod 23 increases the angle at which the upper connecting rod 22, the telescopic main rod 21 and the stretcher 30 as a whole tilt forward.

[0046] It should be noted that when using this body transport device to transport a body, normally, when adjusting the forward tilt angle of the stretcher 30, the folding drive mechanism 25 is not activated, the lower connecting rod 23 is in the extended state and does not move, only the tilting drive mechanism 24 is activated to extend and retract the telescopic main rod 21, thereby driving the upper connecting rod 22 and the stretcher 30 to move. However, depending on the actual situation, both the folding drive mechanism 25 and the tilting drive mechanism 24 can be activated to adjust the height of the stretcher 30, for example, as... Figure 2 As shown, the tilting drive mechanism 24 extends the telescopic main rod 21 (at this time, the height position of the fourth rotating shaft 44 increases), so that the stretcher 30 rotates counterclockwise around the fourth rotating shaft 44 by a certain angle. At the same time, the folding drive mechanism 25 increases the unfolding angle of the lower connecting rod 23 (at this time, the height position of the fifth rotating shaft 45 increases), so that the stretcher 30 rotates clockwise around the fifth rotating shaft 45 by a certain angle, thereby increasing the height of the stretcher.

[0047] like Figure 1 and Figure 2 As shown, in this utility model, the folding drive mechanism 25 includes a second telescopic cylinder (such as an electric push rod). One end of the second telescopic cylinder 25 is rotatably connected to the lower rod portion 232. Specifically, a support block 233 fixedly connected to the lower rod portion 232 can be provided to install the second telescopic cylinder 25. The second telescopic cylinder 25 and the support block 233 are rotatably connected through an eighth rotating shaft 48. The end of the second telescopic cylinder 25 away from the lower rod portion 232 is rotatably connected to the connecting plate 12 of the power track 10 through a ninth rotating shaft 49. By extending the telescopic shaft of the second telescopic cylinder 25, the lower rod 232 rotates clockwise around the sixth pivot 46, causing the second telescopic cylinder 25 to rotate clockwise around the ninth pivot 49. Simultaneously, the lower rod 232 causes the upper rod 231 to rotate counterclockwise around the second pivot 42, thereby reducing the angle between the lower rod 232 and the upper rod 231. By shortening the telescopic shaft of the second telescopic cylinder 25, the lower rod 232 rotates counterclockwise around the sixth pivot 46, causing the second telescopic cylinder 25 to rotate counterclockwise around the ninth pivot 49. Simultaneously, the lower rod 232 causes the upper rod 231 to rotate clockwise around the second pivot 42, thereby increasing the angle between the lower rod 232 and the upper rod 231.

[0048] like Figure 1As shown, in another preferred embodiment, the powered track 10 includes a front flat section 101 that contacts the ground and an upwardly inclined rear section 102 located behind the front flat section. The rear inclined section 102, compared to a completely straight section, reduces the footprint of the new track structure. When the stretcher 30 is used while tilted forward via the support frame 20, the overall volume is smaller, facilitating the operation of the body transport device in confined spaces such as stairwells and landing platforms.

[0049] like Figure 1 As shown, in another preferred embodiment, the bottom of the stretcher 30 has a slide rail 31 extending along its length. The connection between the support frame 20 and the stretcher 30 is provided with an adjusting slider 32. The adjusting slider 32 is slidably connected to the slide rail 31 and fixed by fasteners (such as bolts). Specifically, the upper end of the telescopic main rod 21 is rotatably connected to a rear adjusting slider 32 through a fourth pivot 44, and the upper end of the upper connecting rod 22 is rotatably connected to a front adjusting slider 32 through a fifth pivot 45.

[0050] When assembling the body transport device, by moving the position of the adjusting slider 32 on the slide rail 31, the distance between the two adjusting sliders 32 in the length direction of the stretcher 30 can be adjusted to adjust the forward tilt angle range of the stretcher 30; on the other hand, the front and rear positions of the stretcher 30 relative to the powered track 10 can be adjusted. When the stretcher 30 is unfolded at its maximum forward tilt angle, the front end of the stretcher 30 is close to the front end of the powered track 10, making the structure of the body transport device more compact in the bent state. In addition, the rear section of the powered track 10 is an upward tilted rear section 102, which further reduces the size in the front and rear direction, making it particularly suitable for narrow spaces on staircase turning platforms.

[0051] More preferably, after the distance between the two adjusting sliders 32 along the length of the stretcher 30 is determined, in addition to fixing the position of the adjusting sliders 32 with bolts, a support block 26 is also provided to fix the distance between the two adjusting sliders 32 in order to increase stability. The front and rear ends of the support block 26 can be fixed to the two adjusting sliders 32 respectively, or as... Figure 1 As shown, the front and rear ends of the support block 26 are respectively fitted onto the fourth rotating shaft 44 and the fifth rotating shaft 45.
