Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a battery installation device and a medical equipment trolley. Background Art

[0002] External batteries are essential for medical devices like ventilators to provide backup power and ensure proper function in the event of a power outage (i.e., mains power) or during patient transport (where an external power outlet is unavailable). Therefore, reliably and compactly arranging an external power supply on a ventilator cart is crucial to ensuring proper function.

[0003] The existing technology is to place the external battery in the battery compartment above the chassis of the ventilator trolley, such as Figure 1 The figure shows a conventional ventilator trolley. The battery compartment is generally mounted above the chassis, and nothing is usually placed below the chassis. With this conventional trolley structure, the battery compartment is also placed above the chassis. This, combined with other equipment such as the ventilator, results in a high center of gravity for the entire ventilator trolley, which is detrimental to its stability. Furthermore, the battery compartment being placed above the chassis takes up space above the trolley chassis, making it difficult to install more equipment that works with the ventilator.

[0056] The following is a further detailed description of a battery installation device and a medical equipment trolley proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. The same or similar figure marks in the drawings represent the same or similar parts. It should be understood that the drawings in the specification do not necessarily show the specific structure of the present invention in proportion, and the illustrative features used to illustrate certain principles of the present invention in the drawings in the specification will also adopt a slightly simplified drawing method.

[0057] The core idea of ​​the present invention is to provide a battery installation device and a medical equipment trolley to solve the problems in the prior art of unstable center of gravity of medical equipment trolleys and occupied space above the trolley chassis.

[0058] To realize the above idea, the present invention provides a battery installation device for installing an external battery of a medical device on a medical device trolley, which can be installed in the space below the chassis of the medical device trolley. Figure 2a-2cA medical equipment trolley provided by the present invention is shown. The lower half of the medical equipment trolley mainly includes the following components: a chassis 2, a column 3, casters 4 and a battery installation device 1. Installing the battery installation device 1 under the chassis 2 can lower the center of gravity of the medical equipment trolley, improve the stability of the medical equipment trolley, and does not occupy the space above the chassis 2 of the medical equipment trolley, which is conducive to installing more other equipment that cooperates with the medical equipment on the medical equipment trolley.

[0059] Taking a transport ventilator as an example, during transport, the ventilator requires external batteries for power. The existing technology places the external batteries above the chassis, which not only results in an unsightly overall design, but also requires reinforcement of the trolley frame and chassis to withstand the weight of at least two external batteries and the battery compartment that holds them. The battery compartment of the existing transport ventilator is manufactured using an integrated molding process with the trolley's columns. This makes it impossible to use the same columns as other types of ventilators, which inadvertently increases manufacturing costs. If the trolley columns could be simplified to resemble the columns of other types of ventilators, eliminating the need for additional columns would reduce manufacturing costs. The inventors of the present invention considered that while installing the external batteries below the chassis could address the unstable center of gravity, the specific placement of the external batteries still requires consideration. If the external batteries can be made relatively small or lightweight, the optimal solution would be to symmetrically place multiple external batteries on the connecting bracket between the trolley's casters and chassis. However, existing external batteries are generally large and heavy. Therefore, the external battery is installed under the chassis 2, and the position of the external battery corresponds to the position of the column 3, that is, the center of gravity of the column 3 and the center of the chassis 2 and the center of the external battery are on the same straight line, so that the stability of the entire trolley is higher.

[0060] The following combination Figure 2a-7c A battery installation device provided by one embodiment of the present invention is introduced in detail.

[0061] Please refer to Figures 2a to 7c The present invention provides a battery installation device for installing an external battery of a medical device on a trolley of the medical device. The battery installation device is installed in the space below the chassis 2 of the medical device trolley, and includes: a battery compartment 10 and a battery compartment door 13; a side opening of the battery compartment 10 forms a receiving space with a first opening, and the receiving space is used to receive an external battery; the battery compartment 10 is rotatably connected to the chassis 2 of the trolley, and the rotating connection is located on the other side of the battery compartment 10 opposite to the first opening; the battery compartment door 13 is detachably connected to the battery compartment 10 to close the first opening.

[0062] During use, the external battery can be placed into the accommodating space through the first opening on the side, and then the first opening is closed by the battery compartment door 13, so that the external battery can be firmly placed in the space below the chassis 2 of the medical equipment trolley. The external battery can be loaded and unloaded and maintained by opening the battery compartment door 13. Moreover, in the present invention, the battery compartment 10 can be rotated relative to the chassis 2. In this way, when installing or removing the battery, the battery compartment 10 can be rotated downward first, increasing the operating space for loading and unloading the external battery and avoiding the influence of the chassis 2 on loading and unloading. Moreover, the battery compartment 10 as a whole and the chassis 2 are also a rotatable and detachable structure, which not only keeps the chassis structure of medical equipment such as the transport ventilator unchanged, but also allows many chassis components of the transport ventilator to be shared with other ventilators, reducing manufacturing costs; on the other hand, the external battery can be easily replaced during long-term transportation.

[0063] In the solution of the present invention, by installing the battery mounting device in the space below the trolley chassis 2, compared with the solution of installing it above the chassis in the prior art, the center of gravity of the trolley can be effectively lowered, making the trolley more stable; in addition, by installing it in the space below the trolley chassis 2, it does not occupy the space above the chassis 2, which is conducive to installing more other equipment on the vehicle that cooperates with the normal operation of the medical equipment.

[0064] In one embodiment of the present invention, a second opening that is in communication with the accommodating space may also be formed on the top of the battery compartment 10. The opening on the top of the battery compartment 10 can expand the accommodating space, thereby increasing the space for placing an external battery.

[0065] Furthermore, the battery compartment 10 can rotate upward or downward about a first direction, which is a direction parallel to the horizontal plane, so that the second opening of the battery compartment 10 is closer to or farther away from the chassis 2. In one embodiment of the present invention, the battery compartment 10 can be rotated both upward and downward based on the dome shape of the chassis 2, and the upward rotation angle is smaller than the downward rotation angle. The upward rotation is to adjust the relative position between the battery compartment 10 and the chassis 2 so that the battery compartment 10 is fixed horizontally by the connection structure; the downward rotation is to increase the operating space for placing the battery.

[0066] Furthermore, the battery mounting device also includes a battery compartment fixing member, which is used to secure the battery compartment 10 to the chassis 2. In this embodiment, in addition to the rotational connection between the battery compartment 10 and the chassis 2, the battery compartment fixing member further enhances the connection strength between the battery compartment 10 and the chassis 2. Preferably, the battery compartment fixing member is disposed on the side of the battery compartment 10 opposite the rotational connection. This allows both sides of the battery compartment 10 to have a connection node with the chassis 2, making the connection more reliable and preventing the battery compartment 10 from falling off.

[0067] Furthermore, the battery compartment 10 includes a battery compartment housing 11 and a fixing bracket 12. The top and a side opening of the battery compartment housing 11 form the accommodating space. The fixing bracket 12 is shaped to match the shape of the battery compartment housing 11 and is installed inside the battery compartment housing 11. The internal space of the fixing bracket 12 is used to accommodate the external battery. The upper portion of the first side panel of the fixing bracket 12 opposite the first opening is provided with a first connecting portion 123. The first connecting portion 123 is used to rotatably connect to the chassis 2 of the trolley. In this embodiment, the shape of the fixing bracket 12 is adapted to the shape of the battery compartment housing 11. This means that after the fixing bracket 12 is installed inside the battery compartment housing 11, its main frame is substantially aligned with the inner wall of the battery compartment housing 11. The internal space of the fixing bracket 12 is substantially equal to the inner cavity space of the battery compartment housing 11. Moreover, after the fixing bracket 12 is rotatably connected to the trolley chassis 2 via its first connecting portion 123, the battery compartment 10 as a whole (including the battery compartment housing 11) can be rotatably connected to the chassis 2. In this solution, the battery compartment shell 11 constitutes the basic outline of the battery compartment 10, and a fixing bracket 12 is provided to realize the connection between the battery compartment 10 and the chassis 2. Moreover, the fixing bracket 12 can be used as a connecting piece to conveniently add more components to the battery compartment 10 to realize more functions of the installation device.

[0068] As one implementation of the present invention, the upper portion of the first side panel is bent outwardly away from the accommodating space to form the first connecting portion 123. Directly bending the first side panel to form the first connecting portion 123, which serves as the rotational connection between the fixing bracket 12 and the chassis 2, can make the rotational connection between the fixing bracket 12 and the chassis 2 more direct and tight, and can also minimize the number of accessories used, effectively saving costs.

[0069] Preferably, the number of the first connection parts 123 can be two, and the upper part of the first side panel near its two ends is bent outward to form two first connection parts 123. Since the battery compartment 10 is heavier as a whole after accommodating the external battery, in order to make the connection between the battery compartment 10 and the chassis 2 more reliable, two first connection parts 123 can be used as rotational connection fulcrums. This can share the force and prevent a single connection point from being damaged and broken due to excessive force, causing the battery compartment 10 to fall off the chassis 2. Of course, those skilled in the art will understand that the number of first connection parts 123 is not limited to one or two, and can also be more, and all of these should be within the scope of protection of the present invention.

[0070] In one embodiment of the present invention, the battery installation device also includes a shaft hanger assembly 15, the shaft hanger assembly 15 includes a shaft hanger body 151 and a shaft 152, the shaft hanger body 151 is an inverted U-shape, including a connecting plate and two opposite hanging plates connected to the connecting plate, the two hanging plates are respectively provided with coaxial shaft holes, the shaft 152 passes through the two shaft holes, and the connecting plate is used to connect to the chassis 2; the first connecting part 123 includes a hook 124, the hook 124 is hung on the shaft 152, and the hook 124 can rotate around the shaft 152 to make the battery compartment 10 rotate around the shaft 152. This solution provides a method for realizing a rotational connection between the battery compartment 10 and the chassis 2. In this method, a rotating shaft hanger assembly 15 is provided. The rotating shaft hanger assembly 15 is connected to the chassis 2 via its connecting plate. For example, one or more connecting holes 153 can be opened on the connecting plate, and the connecting plate can be fixed to the chassis 2 by bolts or the like. Of course, the present invention does not limit the connection method between the connecting plate and the chassis 2. The connection between the two is not limited to the above-mentioned bolt connection, and other connection structures can also be used. The rotating shaft hanger assembly 15 is provided with a rotating shaft 152, and a corresponding hook 124 is provided on the first connecting portion 123 of the fixed bracket 12. In this case, the hook 124 can be hung on the rotating shaft 152, thereby realizing the rotational movement of the battery compartment 10 around the rotating shaft 152, thereby realizing the rotational connection between the battery compartment 10 and the rotating shaft 152.

[0071] As a preferred embodiment, the end of the first connecting portion 123 away from the first side plate is bent downward to form the hook 124. Forming the hook 124 by an integral bending process not only offers the advantages of simple operation, reduced material consumption, and low cost, but also makes the rotational connection between the fixed bracket 12 and the rotating shaft 152 more direct and reliable, and improves transmission efficiency.

[0072] Furthermore, the rotating shaft 152 includes a stopper cap and a shaft rod. The stopper cap is located at one end of the shaft rod. The diameter of the stopper cap is larger than the diameter of the rotating shaft hole, while the diameter of the shaft rod is smaller than the diameter of the rotating shaft hole. The rotating shaft hanger assembly 15 also includes a stopper ring 154. The diameter of the stopper ring 154 is larger than the diameter of the rotating shaft hole. The other end of the shaft rod passes through the two rotating shaft holes and is connected to the stopper ring 154. The stopper cap and stopper ring 154 can always constrain the rotating shaft 152 within the two rotating shaft holes, preventing the rotating shaft 152 from falling out and causing the battery compartment 10 to fall off.

[0073] In order to prevent the limiting ring 154 from falling out, a groove matching the limiting ring 154 is formed at the other end of the shaft, and the limiting ring 154 is sleeved on the groove.

[0074] In another embodiment of the present invention, the shaft hanger assembly 15 further includes a pressure plate 155, which is vertically connected to the bottom surface of the connecting plate and is located on the side of the shaft 152 away from the battery compartment 10. The pressure plate 155 is used to press the first connecting portion 123 when the battery compartment 10 is in a horizontal position to prevent the battery compartment 10 from turning downward around the rotation axis 152 under the action of gravity. Specifically, Figure 6 As shown, when the hook 124 is hooked on the rotating shaft 152, the battery compartment 10 can be rotated around the rotating shaft 152 through the hook 124. When installing the battery, the battery compartment 10 is rotated downward. After the battery is installed, the battery compartment 10 is rotated upward to a horizontal position and the battery compartment 10 is pushed in the direction close to the rotating shaft 152. At this time, the first connecting part 123 will move to the bottom of the pressure plate 155, and the pressure plate 155 will limit the first connecting part 123. In this way, even if the battery compartment 10 wants to continue to flip downward around the rotating shaft 152 due to gravity, the downward pressure of the pressure plate 155 on the first connecting part 123 can prevent the battery compartment 10 from rotating downward, thereby locking the battery compartment 10 in a horizontal position.

[0075] As a preferred solution, the side of the connecting plate away from the battery compartment 10 is bent downward to form the pressing plate 155 .

[0076] In one embodiment of the present invention, the shaft hanger assembly 15 further includes two guide plates 156. Each guide plate 156 is formed by bending outwardly from one side of the hanger plate near the battery compartment 10 in a direction away from the other hanger plate. Because the shaft hanger assembly 15 is fixed to the lower portion of the chassis 2 of the medical equipment trolley, it is not visible when the battery mounting device 1 is mounted, which makes operation somewhat difficult. The two guide plates 156 of the shaft hanger assembly 15 are formed into a trumpet-like shape with the opening facing outward. In this way, they can guide the hook 124 of the fixed bracket 12, allowing the hook 124 to be conveniently guided through the trumpet mouth and hooked to the shaft 152.

[0077] In the battery mounting device of the present invention, the fixing bracket 12 further includes a second side panel and a third side panel adjacent to the first side panel. A second connecting portion 122 is provided on the upper portion of the second side panel and / or the third side panel near the first opening. The second connecting portion 122 cooperates with the battery compartment fixing member to secure the fixing bracket 12 to the chassis 2. To further secure the connection between the battery compartment 10 and the chassis 2, in addition to the rotational connection, the fixing bracket 12 is further secured to the chassis 2 using the battery compartment fixing member by providing a second connecting portion 122 on the fixing bracket.

[0078] Preferably, the second connection portion 122 includes a bent lug formed by bending the upper portion of the second side panel and / or the third side panel near the first opening outwardly away from the accommodating space. The side of the fixing bracket 12 is directly bent to form the second connection portion 122. The second connection portion 122 serves as the connection portion between the fixing bracket 12 and the chassis 2, which can make the connection between the fixing bracket 12 and the chassis 2 tighter, and can minimize the number of accessories used, effectively saving costs. Of course, it can be understood by those skilled in the art that the second connection portion 122 is not limited to the above-mentioned bent lug structure, but can also be other connection structures. For example, a detachable connection between the fixing bracket 12 and the chassis 2 can be achieved by a snap connection, etc., and these do not exceed the scope of protection of the present invention.

[0079] Preferably, the bent lug is provided with a first bolt hole 125, which cooperates with the battery compartment fixing member to fix the fixing bracket 12 to the chassis 2. The bolt connection is firm and reliable, simple to operate, easy to disassemble, and low in cost.

[0080] Furthermore, the battery compartment fixing member includes a screw, and a second bolt hole 126 connected to the first bolt hole 125 is also provided on the bent lug, and the second bolt hole 126 is located on the side of the first bolt hole 125 close to the first side panel; the aperture of the second bolt hole 126 is D2, the aperture of the first bolt hole 125 is D1, and the nut diameter of the screw is D0, D2>D0>D1. In this solution, two bolt holes, 125 and 126, are provided. The first bolt hole 125 plays a locking role, and the second bolt hole 126 plays a role of guiding the slide rail. Specifically, when the battery compartment 10 is fixed to the chassis 2, the screw is fixed to the chassis 2 through the first bolt hole 125; when the external battery needs to be removed and replaced, the screw can be loosened, but the screw is not removed to prevent the screw from accidentally falling and being difficult to find. At this time, the battery compartment 10 is pushed toward a position away from the rotating connection, and the screw fixed on the chassis 2 moves relatively from the first bolt hole 125 to the second bolt hole 126. At this time, the hook 124 at the rotating connection just moves to the rotating shaft 152. In this way, since the diameter D2 of the second bolt hole 126 is larger than the nut diameter D0 of the screw, the battery compartment 10 can be directly removed from the screw. At this time, the battery compartment 10 can be rotated downward around the rotating shaft 152 through the hook 124 to replace or remove the battery. In this way, the battery can be easily replaced and disassembled without removing parts other than the battery, which makes replacement more efficient, saves time in removing screws, and avoids the problem of small parts accidentally falling and being unable to find them during disassembly.

[0081] Furthermore, a third bolt hole 127 is formed on the bent lug, and a threaded hole matching the third bolt hole 127 is formed on the outer wall of the battery compartment housing 11 near the bent lug. The fixing bracket 12 is threadedly connected to the threaded hole of the battery compartment housing 11 through the third bolt hole 127. Of course, the present invention is not limited to this method for connecting the battery compartment housing 11 and the fixing bracket 12. The use of a threaded connection is only one method that is simple to operate and reliable. Those skilled in the art will understand that other connection methods can also be used to achieve the connection between the battery compartment housing 11 and the fixing bracket 12.
