Description

Technical Field

[0001] This utility model relates to the field of medical vehicle compartments, and in particular to an expandable structure for a medical vehicle compartment. Background Technology

[0002] Existing ambulances suffer from cramped spaces and low equipment integration, making it difficult to meet complex treatment needs and lacking intelligent environmental control and telemedicine support. As emergency medical needs evolve, vehicle-mounted medical compartments are being developed with modular designs to expand functional areas, such as independent spaces for intensive care, surgery, and isolation, significantly improving treatment efficiency; a similar prior art is disclosed in patent number CN222832681U.

[0003] However, existing medical vehicles only have one hinged door with a small opening. When it is necessary to move larger equipment or require a larger working space, the entire panel structure of the hinged door needs to be disassembled to expose the internal space. Not only is the disassembly and assembly process complicated, but even after opening, the internal working space is still small, and it cannot achieve the effect of external sunshade or expanding the ground area.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] In the first embodiment, such as Figure 1 As shown, this utility model provides an expandable structure for a medical vehicle body 1, including a body 1. A hinged door 101 and a pedal 102 are installed at one end of the body 1. A rotating shaft 103 is installed between the pedal 102 and the body 1, and the pedal 102 rotates along the rotating shaft 103.

[0026] In the normal structure, both medical equipment and medical beds enter through the hinge door 101. By rotating the rotating shaft 103, the pedal 102 is lowered to form an inclined shape, which facilitates the transport of medical equipment, etc.

[0027] However, when dealing with large equipment or when bunk beds need to be installed, the entire panel structure of the hinge door 101 needs to be disassembled in order to fit larger medical equipment or bed frames. In particular, when an open medical setting is required, the smaller hinge door 101 cannot expand its usable area and internal space to facilitate the use of medical equipment in other vehicles.

[0028] An upper hinge plate 2 is installed on one side of the body 1, and a lower hinge plate 3 is installed at the bottom of the upper hinge plate 2. The upper hinge plate 2 is rotatably connected to the body 1 via an upper rotating shaft 201, and the lower hinge plate 3 is rotatably connected to the body 1 via a lower rotating shaft 301. A retractable support leg 4 is also installed on the surface of the lower hinge plate 3. The support leg 4 is fixed to the upper hinge plate 2 via a bottom bolt 402. The support leg 4 is used to support the lower hinge plate 3 after rotation.

[0029] The upper hinge plate 2 and the carriage are fixed at a fixed rotation angle by a support assembly 5. The support assembly 5 includes a groove 501, a support rod 502 and an outer recess 503, and the outer recess 503 is located on the surface of the carriage. The length of the support rod 502 is the same as the length of the groove 501, and a spring telescopic rod 504 is installed between the support rod 502 and the groove 501. The spring of the spring telescopic rod 504 is a tower spring.

[0030] By providing openable upper hinge 2 and lower hinge 3 on the sides of the carriage, the side structure of the carriage can be directly unfolded when needed, providing a wider range of movement and allowing multiple hospital beds to enter directly from the side, such as... Figure 1 As shown, the upper hinge plate 2 is mainly supported by the rotation of the upper pivot 201 and the support assembly 5. Figure 2 In this form, the lower hinge plate 3, after being rotated via the lower pivot 301, is supported by the bottom support leg 4, thereby facilitating the large-area expansion of the internal space for transporting patients or placing larger equipment, such as ventilators.

[0031] In a further embodiment, supports 302 are installed at both ends of the top of the outer surface of the lower hinge plate 3. A rotating shaft 303 is installed on the inner side of the support 302. The support leg 4 is sleeved on the surface of the rotating shaft 303 and rotates axially. A base 401 is installed on the top of the support leg 4. A bottom bolt 402 is installed on the surface of the base 401, and the bottom bolt 402 is threadedly connected to the upper hinge plate 2.

[0032] Since the upper hinge plate 2 and the lower hinge plate 3 are separate, their joints are prone to shaking during vehicle transportation, especially since the opening direction of the upper pivot 201 and the lower pivot 301 is outward; therefore, the outrigger 4 should be positioned such that, before flipping... Figure 1 As shown, a base 401 is provided at the top, allowing the bottom bolt 402 to pass through the base 401 and be fixed to the upper hinge plate 2, thereby achieving the fixing function between the upper hinge plate 2 and the lower hinge plate 3.

[0033] In a further embodiment, the outrigger 4 includes a fixed rod 403 and a movable cylinder 404. The movable cylinder 404 has holes 405 arranged at equal intervals on its surface. Limiting bolts 406 are installed inside the holes 405. The limiting bolts 406 limit the movable cylinder 404 by passing through the holes 405 at different heights.

[0034] The structure is designed to allow the outrigger 4 to be lowered so that it can be adjusted according to the height of the vehicle and the ground. The movable cylinder 404 slides up and down on the surface of the fixed rod 403, and the fixed rod 403 and the movable cylinder 404 are fixed by the limit bolt 406.

[0035] In a further embodiment, the upper hinge plate 2 is located outside the lower hinge plate 3, and the joints between the upper hinge plate 2 and the lower hinge plate 3 are staggered; a rubber layer is also provided between the upper hinge plate 2 and the lower hinge plate 3, the rubber layer is used to seal the gap between the upper hinge plate 2 and the lower hinge plate 3, a fixing plate 6 is installed on the inner side of the lower hinge plate 3, and connecting bolts 601 are installed at the four corners of the fixing plate 6, and the connecting bolts 601 are fixed to the inner side of the lower hinge plate 3; the upper connecting bolts 601 are located at the junction of the upper hinge plate 2 and the lower hinge plate 3, and the connecting bolts 601 pass through the threaded connection between the lower hinge plate 3 and the upper hinge plate 2;

[0036] This design ensures that the inner side of the lower hinge plate 3 not only has a fixing plate 6 whose height at the four corners can be adjusted via connecting bolts 601, but also that the fixing plate 6, through the connecting bolts 601 at the four corners, creates a seal at the joint between the upper hinge plate 2 and the lower hinge plate 3 when the entire assembly is fixed; that is, the fixing plate 6, when... Figure 2 When unfolded, the front and back can form an inclined structure, allowing external equipment or beds to face inwards, rather than sliding outwards due to the cantilevered inclined structure formed by the lower hinge plate 3.

[0037] In a further embodiment, the spring telescopic rod 504 is installed inside the groove 501 near the outer recess 503. The spring telescopic rod 504 is connected to the groove 501 and the support rod 502 respectively. The surface of the spring telescopic rod 504 is provided with a limiting block, which is used to limit the rotation angle of the support rod 502. The outer recess 503 has an inward concave structure and is used to limit the support rod 502 after it is inserted.

[0038] The specific fixing method of the support rod 502 is mainly that the user takes it out from the groove 501, then rotates it to a certain angle until the limiting block limits the angle of the support rod 502, and then inserts the support rod 502 into the outer recess 503. Because the upper hinge plate 2 will form a downward gravity effect, the support rod 502 will not reverse when it is pressed down. In addition, the spring telescopic rod 504 also uses a tower spring structure, so even when the support rod 502 rotates, it will not generate a large degree of reverse force.

[0039] In a further embodiment, the surface of the base 401 facing the upper hinge plate 2 is vertical and horizontal, and the outer surface of the support 302 is provided with a spline shaft 304 for limiting the rotation shaft 303.

[0040] To make the fixing method of the outrigger 4 more stable, an axially telescopic spline shaft 304 is provided on the outside of the support 302. The outer surface of the spline shaft 304 is rotated and limited to the support 302. That is, the surface of the spline shaft 304 can also have a spline structure and be embedded in the support 302 in the normal state, which only forms an axial back and forth movement effect. After the spline shaft 304 is inserted, the spline on the inner side of the spline shaft 304 will be inserted into the surface of the rotating shaft 303, so that the rotating shaft 303 forms a fixing effect, allowing the outrigger 4 to limit its own rotation angle.

[0041] In summary, the overall structure of this utility model is simple. The opening and closing effect of the side of the compartment is mainly achieved by the upper and lower hinge plates on the side of the compartment. This not only expands the working space, but also allows larger equipment such as ventilators or non-foldable hospital beds to be directly entered into the compartment from the side. Furthermore, it can be used in combination with other compartment structures during outdoor emergency rescue.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
