Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a rolling power supply mechanism suitable for rehabilitation ceiling rails. Background Technology

[0002] Currently, most medical rehabilitation overhead rails on the market do not have on-track charging capabilities, but instead rely on battery storage. This requires medical staff to charge the batteries periodically, and as the battery's storage capacity decreases during use, the frequency of charging increases significantly, causing considerable inconvenience for healthcare workers. Furthermore, most existing on-track charging systems are externally mounted on the track, resulting in a loose structure and exposed current collector arms that accumulate dust, posing a safety hazard over time.

[0003] A search revealed the patent: "An Embedded Power Supply Device for a Rehabilitation Track" (CN202210380463.X), which includes a track. The track is a hollow structure, with insulated rails embedded on both the left and right inner walls. Copper sheets are embedded in the insulated rails, and a power transmission line passes through the track, connecting to the copper sheets. A traveling connecting frame is mounted on the insulated rails via moving wheels. A current collector base is mounted on one side of the traveling connecting frame. A first carbon tongue groove and a second carbon tongue groove are provided in the cavity of the current collector base. A first carbon tongue and a second carbon tongue are respectively mounted in the first carbon tongue groove and the second carbon tongue groove through their own compression springs. The first carbon tongue and the second carbon tongue connected to the compression spring are both connected to one end of the power transmission line. The other end of the power transmission line passes through a wiring plate connected to the current collector base and connects to an external device. In the above structure, the carbon brush may have poor contact in the gaps between the tracks. Furthermore, since the carbon brush is a sliding power source, it may experience unevenness when passing through the gaps, which could lead to breakage in severe cases. This could cause the equipment to malfunction or even lose power, thus affecting the patient. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Example like Figure 1 , Figure 2 and Figure 3As shown, a rolling power-collecting mechanism suitable for a rehabilitation ceiling track includes a guide wheel mounting base 1. The top of the guide wheel mounting base 1 is connected to a guide wheel 2 for guiding within the guide rail. Both sides of the guide wheel mounting base 1 are connected to load-bearing wheels 3 that slide within the guide rail. The end of the guide wheel mounting base 1 is connected to a current collector base 4. The left and right sides of the current collector base 4 are respectively provided with a left mounting groove 5 and a right mounting groove 6. The left mounting groove 5 and the right mounting groove 6 are respectively connected to a left wheel type power-collecting component 7 and a right wheel type power-collecting component 8 with the same structure that can adaptively fit against the inner wall of the guide rail. The left-hand power-collecting assembly 7 includes a carbon brush wheel connecting rod 71, a conductive connecting rod 72, and a carbon brush roller 73. The carbon brush wheel connecting rod 71 and the conductive connecting rod 72 are movably connected to the left mounting groove 5 on the same side via a first pin 74. The other side of the carbon brush wheel connecting rod 71 and the conductive connecting rod 72 are connected via a second pin 75. The carbon brush wheel connecting rod 71 and the conductive connecting rod 72 are opposite each other and have a gap between them. A torsion spring 76 is fitted on the first pin 74 located within the gap to adaptively press the carbon brush roller 73 against the inner wall of the guide rail. The carbon brush roller 73 is fitted on the second pin 75 located within the gap.

[0021] In this embodiment, the torsion spring 76 is a V-shaped torsion spring, one end of which contacts the current collector seat 4, and the other end of which contacts the stop block on the carbon brush wheel connecting rod 71. The V-shaped torsion spring forces the wheel power taking component to remain in contact with the inner wall of the track and thus take power.

[0022] In this embodiment, the current collector base 4 has a wiring hole 77 that communicates with the conductive connecting rod, and the guide wheel mounting base 1 has a wire channel that communicates with the wiring hole. By connecting the wire channel of the guide wheel mounting base to the wiring hole, one end of the power take-up wire is connected to the conductive connecting rod 72, and the other end passes through the wiring hole and then through the wire channel inside the guide wheel mounting base to connect to the operating equipment. This prevents the power take-up wire from being exposed on the outside and potentially coming into contact with the guide rail, ensuring that the power take-up wire will not be scratched during operation and guaranteeing its safety. Furthermore, the current collector base 4 is made of hard plastic, which helps prevent the risk of electric shock.

[0023] In this embodiment, a compression spring 78 is fitted onto the second pin 75. The compression spring 78 is located between the second pin and the conductive connecting rod 72. After the conductive connecting rod contacts the top surface of the carbon brush roller, it transmits electricity to the rear wire. The compression spring ensures that the conductive connecting rod is always in contact with the top surface of the carbon brush roller 73, thereby ensuring continuous power supply and eliminating the risk of power failure. This ensures that the device is always powered and guarantees the safety of the patient during operation. The carbon brush roller is made of graphite copper, which reduces wear and improves overall power supply efficiency.

[0024] In this embodiment, the first pin 74 and the second pin 75 connect the carbon brush wheel connecting rod 71 and the conductive connecting rod 72 through a fixing plate.

[0025] In the embodiment, under the action of their respective torsion springs, the edges of the carbon brush rollers 73 in the left wheel power-taking assembly 7 and the right wheel power-taking assembly 8 protrude beyond the edge of the guide wheel 2, so that the carbon brush rollers 73 are always in contact with the inner wall of the guide rail and can ensure the stability of power taking when the left wheel power-taking assembly 7 and the right wheel power-taking assembly 8 move anywhere.

[0026] In this embodiment, the guide wheel 2 is connected to the guide wheel mounting base 1 via a guide wheel bearing and guide wheel shaft screws, and the load-bearing wheel 3 is connected to the guide wheel mounting base 1 via a load-bearing wheel bearing and a fixed shaft. This improves the flexibility of movement of the guide wheel and the load-bearing wheel.

[0027] The working principle of this utility model is as follows: In specific work, such as Figure 4 As shown, the rolling power-taking mechanism is placed inside the overhead track. The load-bearing wheel moves inside the track, while the guide wheel acts as a guide within the track. The carbon brush rollers in the left and right wheel power-taking components can always roll in contact with the inner wall of the track and take power under the drive of the V-shaped torsion spring, carbon brush wheel connecting rod, and conductive connecting rod, thereby improving stable power taking and better gap-crossing ability, thus enhancing the overall operating capability of the equipment.

[0028] Note that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
