[0002] When the male and female connectors of a device are connected, they need to be aligned. The connection method between the male and female connectors can be a contact connection. In this case, a connecting portion is required to guide and align so that the male and female connectors can be aligned. Through the stable connection of the connecting portion, the male and female connectors can maintain stable contact. The connecting portion is divided into two parts to correspond to the male and female connectors respectively. The two parts of the connecting portion are connected together by a plugging method. Since the two parts of the connecting portion need to maintain a stable connection, the structures of the two parts of the connecting portion for plugging need to be tightly plugged together, resulting in difficulty in inserting the plugging structure during the plugging process.

[0003] Therefore, due to the technical problem that the components to be aligned and connected are difficult to insert, a new joint positioning mechanism, a device and a connection method need to be designed.

[0065] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0066] As used herein, phrases such as "in one embodiment", "according to one embodiment", "in some embodiments", etc. generally refer to the fact that the specific features, structures or characteristics after such phrases can be included in at least one embodiment of the present disclosure. Therefore, the specific features, structures or characteristics can be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, terms such as "example", "exemplary", etc. are used "for the purpose of serving as an example, instance or illustration. Any embodiment, aspect or design described herein as "example" or "exemplary" is not necessarily construed as being preferred or superior to other embodiments, aspects or designs. On the contrary, the use of terms such as "example", "exemplary", etc. is intended to present concepts in a specific manner.

[0067] It has been found through research that the male and female connectors of the devices in the prior art can be connected in a contact connection manner. At this time, other components are required to align and connect so that the male and female connectors can be aligned and stably connected. For example, the first connecting portion and the second connecting portion are used for alignment and connection, so that the male and female connectors can be aligned and stably connected together. Since the stable connection between the male and female connectors needs to be maintained, the dimensions of the portions of the first connecting portion and the second connecting portion for connection are adapted to each other, and thus the first connecting portion and the second connecting portion can be stably connected together. The first connecting portion and the second connecting portion need to be tightly connected together to maintain the stability of the connection. The size of the column of the second connecting portion is almost the same as the size of the jack of the first connecting portion, which makes it difficult for the second connecting portion to be inserted into the first connecting portion, resulting in difficult installation.

[0068] However, due to the adaptation of their sizes, it is difficult to insert them when they are plugged together, resulting in difficult installation.

[0069] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0070] As Figure 1 and Figure 6 shown, at least one disclosed embodiment provides a joint positioning mechanism, including: a connecting frame 3, and a first connecting portion 1 provided on the connecting frame 3; a second connecting portion 2 adapted to the first connecting portion 1 is provided on a connecting plate, and the first connecting portion 1 is adapted to connect the second connecting portion 2; the second connecting portion 2 includes: a fixed sleeve 21 and a connecting column 22; one end of the fixed sleeve 21 is a connecting end, and this connecting end is fixed on the connecting plate, and the other end of the fixed sleeve 21 is provided with an open end; the connecting column 22 is inserted into the fixed sleeve 21, and the connecting column 22 is rotatably connected to the fixed sleeve 21; one end of the connecting column 22 extends out from the open end of the fixed sleeve 21; the extension of the connecting column 22 from the fixed sleeve 21 enables the connecting column 22 to be inserted into the second sleeve 12; the connecting column 22 is adapted to be inserted into the second sleeve 12 of the first connecting portion 1, and the connecting column 22 rotates during the insertion process; the alignment and connection of the first connecting portion 1 and the second connecting portion 2 are realized, so that the corresponding male and female connectors of the device can be aligned and stably connected, and during the connection process of the first connecting portion 1 and the second connecting portion 2, rotation enables the two to be connected more smoothly and conveniently.

[0071] As Figure 2 and Figure 3As shown, in an alternative embodiment, a limiting ring 211 is provided on the inner wall of the fixed sleeve 21, and the limiting ring 211 is disposed near the connection end of the fixed sleeve 21; the connecting column 22 passes through the limiting ring 211, and the outer wall of the connecting column 22 contacts the inner wall of the limiting ring 211; a first ring body 221 is provided on the connecting column 22, and the first ring body 221 is disposed between the limiting ring 211 and the connection end of the fixed sleeve 21, and there is a gap between the outer wall of the first ring body 221 and the inner wall of the fixed sleeve 21; the inner part of the fixed sleeve 21 can be divided into two spaces by the limiting ring 211, and lubricating oil can be stored in the space between the limiting ring 211 and the connection end of the fixed sleeve 21. The lubricating oil can lubricate during the process of inserting the connecting column 22 into the second sleeve 12, facilitating the insertion of the connecting column 22.

[0072] In an alternative embodiment, a moving sleeve 23 is sleeved on the connecting column 22, and the moving sleeve 23 is located between the outer wall of the connecting column 22 and the inner wall of the fixed sleeve 21; the moving sleeve 23 extends from the open end of the fixed sleeve 21; a first spring 231 is provided between the moving sleeve 23 and the side wall of the limiting ring 211; a convex block 232 is provided on the inner wall of the moving sleeve 23; a spiral groove 222 is provided on the outer wall of the connecting column 22, and the convex block 232 is located in the spiral groove 222, and the convex block 232 is slidably connected with the spiral groove 222; the side of the moving sleeve 23 extending out of the fixed sleeve 21 is an inclined surface; when the convex block 232 slides in the spiral groove 222, it drives the connecting column 22 to rotate; during the process of inserting the connecting column 22, the moving sleeve 23 will slide towards the inside of the fixed sleeve 21. During the sliding process of the moving sleeve 23, the convex block 232 will move along the spiral groove 222, causing the connecting column 22 to rotate. Rotating during the insertion of the connecting column 22 can facilitate the insertion of the connecting column 22 into the second sleeve 12; when the moving sleeve 23 moves towards the inside of the fixed sleeve 21, it will compress the first spring 231 to reset the moving sleeve 23 through the first spring 231 after the connecting column 22 is pulled out of the second sleeve 12; the moving sleeve 23 does not rotate during the moving process. For example, the moving sleeve 23 and the limiting ring 211 are connected by the first spring 231 to avoid the rotation of the moving sleeve 23 and ensure the rotation effect of the connecting column 22.

[0073] In an alternative embodiment, a plurality of flow channels 223 are axially formed inside the connecting column 22 along the axis of the connecting column 22; through holes 224 corresponding to the flow channels 223 are radially formed on the first ring body 221 along the radial direction of the first ring body 221; the through holes 224 communicate with the corresponding flow channels 223; an oil outlet is formed at the position where the connecting column 22 extends out of the fixed sleeve 21, and the oil outlet corresponds to and communicates with the flow channel 223; lubricating oil is stored between the inner wall of the connection end of the limiting ring 211 and the fixed sleeve 21; the lubricating oil stored between the connection end of the limiting ring 211 and the fixed sleeve 21 enters the flow channel 223 through the through hole 224, and then flows out of the flow channel 223 through the oil outlet; the flow channel 223 can be inclined downward, that is, the flow channel 223 located at the lowest position of the connecting column 22 is inclined downward during the rotation of the connecting column 22, and the flow channel 223 is lower the farther it is from the connection end of the fixed sleeve 21, so that the lubricating oil in the flow channel 223 can flow toward the oil outlet. When the through hole 224 rotates with the first ring body 221, the through hole 224 will rotate to the lower position of the first ring body 221. At this time, the lubricating oil can flow into the flow channel 223 through the through hole 224, then flow along the inclined flow channel 223 toward the oil outlet, and then flow out of the oil outlet. During the process of inserting the connecting column 22 into the second sleeve 12, the connecting column 22 can be slowly inserted to facilitate the outflow of the lubricating oil.

[0074] In an alternative embodiment, a block 225 is arranged in the oil outlet, and the block 225 protrudes from the side wall of the connecting column 22; the block 225 is slidably connected with the oil outlet; the surface of the block 225 facing the moving sleeve 23 is an inclined surface; when the block 225 protrudes from the side wall of the connecting column 22, the block 225 closes the oil outlet, and when the block 225 moves into the oil outlet, the oil outlet is opened. The sizes of the oil outlet and the block 225 that can achieve this function can both be adopted. For example, the cross-section of the oil outlet is trapezoidal, and the trapezoid is wider the closer it is to the axis of the connecting column 22. The cross-section of the block 225 is trapezoidal, and the trapezoid is wider the closer it is to the axis of the connecting column 22. When the block 225 extends out of the oil outlet, the side wall of the block 225 contacts the side wall of the oil outlet to close the oil outlet. When the block 225 is pressed and moves into the oil outlet, the side wall of the block 225 separates from the side wall of the oil outlet to open the oil outlet; a spring can be arranged between the block 225 and the inner wall of the oil outlet, or a spring can be connected between the block 225 and the flow channel 223, so that the block 225 blocks the oil outlet when not pressed by the spring; the inclined surface of the block 225 contacts the inclined surface of the moving sleeve 23, and the inclined surface of the moving sleeve 23 supports the block 225 to prevent the block 225 from being pressed into the oil outlet when the block 225 is pressed, and to prevent the oil outlet from being opened.

[0075] Such as Figure 4 and Figure 5As shown, in an alternative embodiment, the first connecting portion 1 includes: a first sleeve 11 and a second sleeve 12; one end of the first sleeve 11 is connected to the connecting frame 3, and the other end of the first sleeve 11 is open; the second sleeve 12 is disposed inside the first sleeve 11, and both ends of the second sleeve 12 are open; one end of the second sleeve 12 close to the open end of the first sleeve 11 is located inside the first sleeve 11; a second ring body 13 is disposed between the first sleeve 11 and the second sleeve 12; the second ring body 13 is sleeved on the second sleeve 12; one end face of the second ring body 13 is flush with the open face of the first sleeve 11; when the connecting column 22 is inserted into the second sleeve 12, the second ring body 13 will contact the moving sleeve 23, and the moving sleeve 23 is caused to move into the fixed sleeve 21 by the obstruction of the second ring body 13 to the moving sleeve 23, so that the connecting column 22 rotates.

[0076] In an alternative embodiment, a chamfer is provided on the inner wall of the second sleeve 12, and the chamfer is close to the open face of the first sleeve 11; the second sleeve 12 is adapted to the connecting column 22; a notch 14 is provided on the outer wall of the first sleeve 11; the chamfer of the second sleeve 12 can guide the end of the connecting column 22, so that the connecting column 22 can be aligned with the second sleeve 12 and smoothly inserted into the second sleeve 12; the notch 14 is aligned with the tail end of the second sleeve 12, and when the block 225 exposes the second sleeve 12, it faces the notch 14 position. After the block 225 exposes the second sleeve 12, the inner wall of the second sleeve 12 no longer obstructs the block 225, and the block 225 is caused to extend out of the oil outlet to block the oil outlet by a spring. At this time, the block 225 can contact the end face of the second sleeve 12 to prevent the connecting column 22 from being pulled out of the second sleeve 12.

[0077] When the second connecting portion 2 is not inserted into the first connecting portion 1, the first spring 231 is in a compressed state at this time. The inclined surface of the moving sleeve 23 contacts the inclined surface of the block 225, and the inclined surface of the moving sleeve 23 supports the block 225. At this time, when the block 225 is pressed, the block 225 cannot move into the oil outlet due to the obstruction of the inclined surface of the moving sleeve 23, ensuring that the oil outlet always remains closed and preventing the lubricating oil from flowing out. During the process of inserting the second connecting portion 2 into the first connecting portion 1, the guiding angle of the second sleeve 12 contacts the end of the connecting column 22, guiding the connecting column 22 so that the connecting column 22 can be aligned with the second sleeve 12. Before the guiding angle contacts the block 225, the second ring 13 will first contact the moving sleeve 23. As the connecting column 22 is inserted into the second sleeve 12, the second ring 13 will prevent the moving sleeve 23 from moving with the connecting column 22, and the moving sleeve 23 will move into the fixed sleeve 21. At this time, the inclined surface of the moving sleeve 23 is disengaged from the inclined surface of the block 225. After the block 225 contacts the guiding angle, it will be pressed by the guiding angle and move into the oil outlet, opening the oil outlet. And the movement of the moving sleeve 23 will cause the connecting column 22 to rotate, so that the connecting column 22 rotates during the insertion process into the second sleeve 12 to facilitate the insertion of the connecting column 22. And as the lubricating oil flows out of the oil outlet, the rotation of the connecting column 22 will smear the lubricating oil on the inner wall of the second sleeve 12. The lubricating oil can also facilitate the insertion of the connecting column 22. As the connecting column 22 is inserted, the block 225 will move out of the second sleeve 12. At this time, the inner wall of the second sleeve 12 will not block the block 225. Through the reset of the spring, the block 225 will protrude from the oil outlet again and block the oil outlet. At this time, the block 225 is aligned with the end face of the second sleeve 12. When the connecting column 22 is pulled outwards at this time, the block 225 contacts the end face of the second sleeve 12 to play a blocking role, preventing the connecting column 22 from being pulled out; grooves can be provided on the outer wall of the connecting column 22, and the grooves correspond to the oil outlet, so that the block 225 can move into the oil outlet to be flush with the outer wall of the connecting column 22, preventing the block 225 from protruding from the connecting column 22 and causing the connecting column 22 to be unable to be inserted into the second sleeve 12.

[0078] At least one other disclosed embodiment also provides a device, including: the above-mentioned joint positioning mechanism, the joint positioning mechanism is arranged on the device body; the connecting frame 3 in the joint positioning mechanism is connected to the device body, a female head corresponding to the first connecting portion 1 is arranged on the connecting frame 3, and a male head corresponding to the second connecting portion 2 is arranged on the connecting plate; when the first connecting portion 1 is connected to the second connecting portion 2, the male head and the female head are aligned and connected.

[0079] In an alternative embodiment, at least two first connection parts 1 are provided on the connection frame 3; the female head corresponds to the first connection part 1; after the first connection part 1 is connected to the second connection part 2, the male head is connected to the female head; a spring can be provided on the female head, so that when the male head contacts the female head, a buffering effect is achieved through the spring, avoiding damage to both the male head and the female head caused by the male head hitting the female head. When the block 225 extends out of the second sleeve 12, the male head and the female head are connected in place. At this time, the elastic force of the spring will cause the connecting column 22 to have a tendency to be pulled out of the second sleeve 12, so that the block 225 will contact the end face of the second sleeve 12 to prevent the connecting column 22 from being pulled out of the second sleeve 12, maintaining the stable connection between the male head and the female head; setting at least two first connection parts 1 and the corresponding second connection parts 2 can ensure that when both the two first connection parts 1 and the corresponding second connection parts 2 are aligned, the male head and the female head are also aligned, ensuring the aligned connection and the stability of the connection between the male head and the female head. If there is only one first connection part 1, it cannot be guaranteed that the male head and the female head are also in an aligned state when the first connection part 1 is aligned and connected to the corresponding second connection part 2.

[0080] At least one other disclosed embodiment also provides a connection method using the above-mentioned joint positioning mechanism, including: when the first connection part 1 is connected to the second connection part 2, the male head and the female head are aligned and connected.

[0081] In summary, this joint positioning mechanism includes: a connection frame 3 and a first connection part 1 provided on the connection frame 3; the first connection part 1 corresponds to a matching second connection part 2, and the second connection part 2 is provided on a connection plate. The first connection part 1 is adapted to connect to the second connection part 2; the second connection part 2 includes: a fixed sleeve 21 and a connecting column 22; one end of the fixed sleeve 21 is a connection end, and this connection end is fixed on the connection plate. The other end of the fixed sleeve 21 is provided with an open end; the connecting column 22 is inserted into the fixed sleeve 21, and the connecting column 22 is rotatably connected to the fixed sleeve 21; one end of the connecting column 22 extends out of the open end of the fixed sleeve 21; the connecting column 22 is adapted to be inserted into the second sleeve 12 of the first connection part 1, and the connecting column 22 rotates during the insertion process; it realizes the alignment and connection through the first connection part 1 and the second connection part 2, so that the corresponding male head and female head of the device can be aligned and stably connected, and the two can be connected more smoothly and conveniently through rotation during the connection process of the first connection part 1 and the second connection part 2.
