Description

[Technical field]

[0001] The present invention relates to the technical field of fans, and in particular to a fan connection structure and a magic link fan. [Background technology]

[0002] Existing chassis fans all use a single wire to supply power and control the RGB light, and chassis generally use multiple fans, but due to the limited fan and RGB light interfaces provided by computer motherboards, currently, general fan power supply uses one-to-multi-wire serial connection or hub power supply, and the RGB interface connects multiple fans in series in one-to-two ways, and finally one interface is connected to the light control on the motherboard. The traditional one-to-multi-wire wiring method requires connecting multiple fans, and the wires are very messy and numerous, making it very difficult to manage the wires in the fan installation environment, and there are many connector assemblies, which are prone to poor contact, which affects the use effect of the product. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE PRESENT DISCLOSURE The objective of the present invention is to provide a fan connection structure and a magic link fan for solving at least one of the above problems existing in the prior art. [Means for solving the problem]

[0004] To achieve the above objectives, the present invention uses the following technical solutions:

[0005] The fan connection structure includes a connector and a first connection portion provided on an adjacent fan, the connector including a substrate, the substrate being provided with a second connection portion removably combining with the first connection portion, the first connection portion being provided with a first contact point, the substrate being provided with a second contact point in contact with the first contact point, and the second contact point being electrically connected to a circuit board of the fan.

[0006] In this technical solution, adjacent fans are provided with a first connection part, the connector includes a board, and the board is provided with a second connection part that is detachably combined with the first connection part, so that adjacent fans can be detachably combined with the first connection part through the second connection part on the board, the first connection part is provided with a first contact point, and the board is provided with a second contact point, the first contact point and the second contact point are in contact with each other to be energized, and the second contact point is electrically connected to the circuit board of the fan, so that this design can realize the serial connection energization between the multi-fans 2 without using complicated wires, and the serial connection energization between the multi-fans can be completed by simply connecting the connector to the first connection part between the adjacent fans. This design solves the problem that, when the serial connection energization of the multi-fans can be realized without using physical wires, the conventional design requires the adjacent fans to use a multi-wire serial connection or power supply by a hub, which directly causes the existing wires to be messy and numerous, and the wire management in the fan installation space to be very difficult.

[0007] As needs to be explained, the first connection part is detachably combined with the second connection part, and the detachable combination here includes a detachable fixed connection and a detachable movable connection, and when the detachable fixed connection is selected, after the adjacent fans are fixedly connected by the connector, the relative position fixation between the two fans can be realized without the need for an external auxiliary regulating structure, and the contact effect between the first contact point and the second contact point can be ensured; however, even when the detachable movable connection between the first connection part and the second connection part is used, the fixed regulation of the adjacent fan or multiple fans can be realized by the external auxiliary regulating structure, and the effect of the first contact point and the second contact point contacting and the adjacent fans being connected in series to conduct electricity can also be ensured, and the design purpose of the technical solution can also be achieved in some circumstances. Therefore, the detachable combination between the first connection part and the second connection part is not limited to the detachable fixed connection between them.

[0008] Furthermore, in order to effectively restrict the relative positions of adjacent fans, and similarly maintain a more stable series-connected, energized state between adjacent fans without the auxiliary restricting action of an external auxiliary restricting structure, the first connection portion includes a first restricting structure and a second restricting structure that restrict the free removal of the connector, and the second connection portion includes a third restricting structure that mates with the first restricting structure to realize a removable combination, and a fourth restricting structure that mates with the second restricting structure to realize a removable combination.

[0009] As needs to be explained, the first regulating structure and the third regulating structure are fitted together to realize a detachable combination, and the second regulating structure and the fourth regulating structure are fitted together to realize a detachable combination, that is, there are four detachable combination positions between the connector and two adjacent fans, and through the design of the four detachable combinations, the connector can be removably fixed between the adjacent fans from multiple directions, thereby achieving the effect of a detachable fixed connection.

[0010] Specifically, the engagement between the first and third restriction structures can restrict free removal of the connector in the Z direction, and the engagement between the second and fourth restriction structures can restrict free removal of the connector in the X direction, where the X direction and the Z direction are perpendicular to each other.

[0011] Furthermore, the first regulating structure is slip-fitted into the third regulating structure, and the second regulating structure engages and mates with the fourth regulating structure to provide a releasable fixed connection between the fan and the connector.

[0012] Specifically, the first regulating structure may be a slide groove provided in the fan, the third regulating structure is a slide portion that slides into the slide groove, the second regulating structure is a locking groove provided in the fan, and the fourth regulating structure is a buckle provided on the substrate.

[0013] Of course, the slide groove, slide portion, locking groove and buckle may be selectively provided on the fan or the connector, as long as the connection relationship between the two is maintained.

[0014] For example, the slide groove may be provided in the connector, the slide portion may be provided in the fan, the buckle may be provided in the fan, and the locking groove may be provided in the connector.

[0015] Furthermore, in order to better realize the juxtaposition of adjacent fans, the sliding direction of the first and third restriction structures is the X direction, which is perpendicular to the rotation axis L of the fans.

[0016] Furthermore, the engagement position between the second regulating structure and the fourth regulating structure can be arbitrarily adjusted along the X direction so that the interval between adjacent fans can be arbitrarily adjusted as needed.

[0017] Furthermore, to design a connection method in which the spacing between adjacent fans is fixed, the engagement position between the second regulating structure and the fourth regulating structure is a fixed engagement position, which is at the end of the sliding fit between the first regulating structure and the third regulating structure.

[0018] Specifically, in the above design, the fixed engagement position is at the end of the sliding fit between the first and third regulating structures, i.e., only when the first regulating structure slides relative to the third regulating structure to the limit position of the sliding fit between them, the second regulating structure is engaged with the fourth regulating structure to realize a fixed setting of the spacing between adjacent fans.

[0019] As should be explained, in the actual application process, when adjacent fans need to be arranged side by side in close proximity, the length of the connector is equal to the distance between the two fixed engagement positions when the two adjacent fans are arranged side by side in close proximity.

[0020] In the case where adjacent fans need to be arranged side-by-side with a fixed distance between them, the length of the connector is greater than the distance between the two fixed engagement positions when the two adjacent fans are in close proximity side-by-side.

[0021] Further, the fan is provided with a contact head, and the first contact point is located at the top of the contact head, and the contact head is a spring ejection pin, and the spring ejection pin can be compressed by the position of the first contact point engaging with the second contact point, so as to ensure a close contact effect between the first contact point and the second contact point when the connector is connected to the fan, thereby achieving a current-carrying effect and avoiding poor contact that affects the use effect of the product.

[0022] As needs to be explained, the number of first contact points and the number of second contact points are set in one-to-one correspondence, and the number of first contact points and the number of second contact points can be adaptively increased or decreased according to the needs of functional expansion of the fan.

[0023] For example, an RGB fan needs to have a motor power interface and an RGB light interface. Therefore, when this design is applied to an RGB fan, the numbers of the first contact points and the second contact points are both six, and the numbers of the first contact points and the second contact points for controlling the motor and the RGB light are three, respectively.

[0024] Further, to facilitate effective contact between the second contact point and the first contact point, the connector is provided with a contact surface, a conductive sheet is provided on the contact surface, and the second contact point is located on the conductive sheet.

[0025] With such a design of the conductive sheet, the position of the second contact point is not limited to a fixed point, and point-to-surface contact is made between the surface of the conductive sheet and the first contact point, thereby improving the operational efficiency of the electrical connection between adjacent fans.

[0026] This embodiment further provides a magic link fan, which includes a plurality of fans and the above-mentioned fan connection structure. With this design, the plurality of fans can realize the current flow effect without the need for complicated wire connection, which effectively improves the structural cleanliness in the fan installation environment and reduces the difficulty of wire management.

[0027] In addition, in order to achieve a better connection effect, the upper and lower ends of adjacent fans are both provided with the fan connection structure. Effect of the Invention

[0028] The present invention has the following beneficial effects: In the present technical solution, adjacent fans are provided with a first connection part, the connector includes a board, and the board is provided with a second connection part that is detachably combined with the first connection part, so that adjacent fans can be detachably combined with the first connection part through the second connection part on the board, the first connection part is provided with a first contact point, and the board is provided with a second contact point, the first contact point and the second contact point are in contact with each other to be energized, and the second contact point is electrically connected to the circuit board of the fan, so that the present design can realize the serial connection energization between multiple fans without using complex wires, and the serial connection energization between multiple fans can be completed by simply connecting the connector to the first connection part between the adjacent fans. The present design solves the problem that, when the serial connection energization of multiple fans can be realized without using physical wires, the conventional design requires the adjacent fans to use a multi-wire serial connection or power supply through a hub, which directly causes the existing wires to be messy and numerous, and the wire management in the fan installation space to be very difficult.

[0030] Hereinafter, the present invention will be described in detail with reference to examples. EXAMPLES

[0031] Example 1 As shown in Figures 1 to 15, this embodiment provides a fan connection structure, and includes a connector 1 and a first connection portion provided on an adjacent fan 2, the connector 1 includes a substrate, the substrate is provided with a second connection portion that is detachably combined with the first connection portion, the first connection portion is provided with a first contact point, the substrate is provided with a second contact point that contacts the first contact point, and the second contact point is electrically connected to a circuit board of the fan 2.

[0032] In this technical solution, adjacent fans 2 are provided with a first connection part, the connector 1 includes a board, and the board is provided with a second connection part that is detachably combined with the first connection part, so that adjacent fans can be detachably combined with the first connection part through the second connection part on the board, the first connection part is provided with a first contact point, and the board is provided with a second contact point, the first contact point and the second contact point are in contact with each other to be energized, and the second contact point is electrically connected to the circuit board of the fan 2, so that this design can realize the serial connection energization between multiple fans 2 without using complex wires, and the serial connection energization between multiple fans 2 can be completed by simply connecting the connector 1 to the first connection part between adjacent fans 2. This design solves the problem that, when the serial connection energization of multiple fans 2 can be realized without using physical wires, the conventional design requires the adjacent fans 2 to use a multi-wire serial connection or power supply through a hub, which directly causes the existing wires to be messy and numerous, and the wire management in the fan installation space to be very difficult.

[0033] As needs to be explained, the first connection part is detachably combined with the second connection part, and the detachable combination here includes a detachable fixed connection and a detachable movable connection, and when choosing to use the detachable fixed connection, after the adjacent fans 2 are fixedly connected by the connector 1, the relative position fixation between the two fans 2 can be realized without the need for an external auxiliary regulating structure, and the contact effect between the first contact point and the second contact point can be ensured; however, even when using the detachable movable connection between the first connection part and the second connection part, the fixed regulation of the adjacent fans 2 or multiple fans 2 can be realized by the external auxiliary regulating structure, and the effect of the first contact point and the second contact point contacting and the adjacent fans 2 being connected in series to conduct electricity can also be ensured, and the design purpose of the technical solution can also be achieved in some circumstances. Therefore, the detachable combination of the first connection part and the second connection part is not limited to the detachable fixed connection between them. EXAMPLES

[0034] Example 2 This embodiment is an optimization based on the above-mentioned embodiment 1.

[0035] In order to effectively restrict the relative positions of adjacent fans 2, and similarly maintain the series-connected, energized state between adjacent fans 2 more stably without the auxiliary restricting action of an external auxiliary restricting structure, the first connection portion includes a first restricting structure and a second restricting structure that restrict the free removal of the connector 1, and the second connection portion includes a third restricting structure that mates with the first restricting structure to realize a removable combination, and a fourth restricting structure that mates with the second restricting structure to realize a removable combination.

[0036] As needs to be explained, the first and third regulating structures are mated to realize a detachable combination, and the second and fourth regulating structures are mated to realize a detachable combination, that is, there are four detachable combination positions between the connector 1 and the two adjacent fans 2, specifically, as shown in FIG. 6, the first and second regulating structures of the two fans 2 are respectively detachably combined with the third and fourth regulating structures of the same connector 1 at four positions: A1 (the connection point between the first regulating structure of the first fan C1 and the third regulating structure of the connector 1), A2 (the connection point between the second regulating structure of the first fan C1 and the fourth regulating structure of the connector 1), A3 (the connection point between the first regulating structure of the second fan C2 and the third regulating structure of the connector 1), and A4 (the connection point between the second regulating structure of the second fan C2 and the fourth regulating structure of the connector 1). The design of the four detachable combinations realizes the connector 1 to be detachably fixed between the adjacent fans 2 from multiple directions, thereby achieving the effect of detachable fixed connection.

[0037] As shown in FIG. 6, the engagement between the first and third restriction structures (A1, A3) can restrict free removal of the connector 1 in the Z direction, and the engagement between the second and fourth restriction structures (A2, A4) can restrict free removal of the connector 1 in the X direction, where the X direction and the Z direction are perpendicular to each other. EXAMPLES

[0038] Example 3 This embodiment is an optimization based on the above-mentioned embodiment 2.

[0039] As shown in Figures 4 to 6 and 9 to 12, the first regulating structure is slip-fitted into the third regulating structure, and the second regulating structure engages and fits with the fourth regulating structure to provide a removable fixed connection between the fan 2 and the connector 1.

[0040] Specifically, the first regulating structure may be a slide groove 3 provided in the fan 2, the third regulating structure is a slide portion 4 that slides into the slide groove 3, the second regulating structure is a locking groove 5 provided in the fan 2, and the fourth regulating structure is a buckle 6 provided on the substrate.

[0041] Of course, the slide groove 3, the slide portion 4, the locking groove 5 and the buckle 6 may be selectively provided on the fan 2 or the connector 1, provided that the connection relationship between them is maintained.

[0042] For example, the slide groove 3 may be provided in the connector 1, the slide portion 4 may be provided in the fan 2, the buckle 6 may be provided in the fan 2, and the locking groove 5 may be provided in the connector 1.

[0043] As should be explained, in order to realize the alignment between the connector 1 and the frame of the fan 2, and at the same time to easily realize the guiding action for the connection between the first and third regulating structures and the connection between the second and fourth regulating structures, a guide structure is provided between the fan 2 and the connector 1, specifically, the guide structure may be a guide groove 7 provided on the fan 2, and the substrate and the guide groove 7 are slidingly fitted together, in such a design, the surface of the substrate that is in close contact with the guide groove 7 is the contact surface, and the second contact point is located on the contact surface. Also, in such a design, there are two slide grooves 3, which are symmetrically provided on both sides of the guide groove 7, the bottom of the guide groove 7 is in the same horizontal plane as the bottom of the slide groove 3, and the openings of the two slide grooves 3 are opposite to each other, and in the process of mounting the connector 1, the substrate only needs to be pushed inward by an appropriate distance in the direction of extension of the guide groove 7, and the appropriate position of pushing inward is based on the realization of the engagement and fitting of the second and fourth regulating structures, such as the engagement of the locking groove 5 with the buckle 6.

[0044] Of course, in addition to the above design, the sliding fit structure between the substrate and the guide groove 7 may be such that the substrate is provided with the guide groove 7, and the fan 2 is provided with a guide portion 8 which is slidingly fitted into the guide groove 7, in which case the surface in the guide groove 7 that is in close contact with the guide portion 8 is the contact surface, and the second contact point is located on the contact surface, which does not affect the realization of the purpose of this design.

[0045] As needs to be explained, in order to achieve a better contact effect, the contact surface is preferably provided on the bottom surface of the substrate or the groove bottom surface of the guide groove 7 of the substrate. EXAMPLES

[0046] Example 4 This embodiment is an optimization based on the above-mentioned embodiment 3.

[0047] In order to more effectively realize the juxtaposition of adjacent fans 2 , the sliding direction of the first and third restriction structures is the X direction, which is perpendicular to the rotation axis L of the fan 2 . EXAMPLES

[0048] Example 5 This embodiment is an optimization based on the above-mentioned embodiment 4.

[0049] The engagement position between the second regulating structure and the fourth regulating structure can be arbitrarily adjusted along the X direction so that the interval between the adjacent fans 2 can be arbitrarily adjusted as needed.

[0050] Specifically, as shown in FIG. 7, FIG. 8, and FIG. 14-FIG. 15, when the guide groove 7 is provided on the fan 2, the guide groove 7 has an engagement edge 9 at both edges thereof, and correspondingly, the board has two engagement arms 10 symmetrically provided thereon, and the two engagement arms 10 are each provided with an engagement head 11, and the engagement head 11 engages with and fits into the corresponding engagement edge 9, and in the process of the board moving along the guide groove 7, the engagement head 11 can be engaged at different positions of the engagement edge 9 along the length direction of the engagement edge 9. In this design, the second regulating structure includes an engagement edge, and the fourth regulating structure includes an engagement arm 10 and an engagement head 11. Preferably, the engagement edge 9 is a corrugated engagement edge, and the engagement head 11 is an arc-shaped engagement head, and when manipulating the relative position between the connector 1 and the fan 2, the arc-shaped engagement head can be engaged with any arc-shaped recess of the corrugated engagement edge. This design realizes that the power supply and light control can be turned on without the fans being adjacent to each other, and can greatly improve the flexibility of the fan installation position. EXAMPLES

[0051] Example 6 This embodiment is an optimization based on the above-mentioned embodiment 4.

[0052] To design a connection method in which the spacing between adjacent fans 2 is fixed, the engagement position between the second regulating structure and the fourth regulating structure is a fixed engagement position, and the fixed engagement position is at the end of the sliding fit between the first regulating structure and the third regulating structure.

[0053] Specifically, in the above design, the fixed engagement position is at the end of the sliding fit between the first and third regulating structures, i.e., only when the first regulating structure slides relative to the third regulating structure to the limit position of the sliding fit between them, the second regulating structure is engaged with the fourth regulating structure, thereby realizing a fixed setting of the spacing between adjacent fans 2.

[0054] As should be explained, in the actual application process, when adjacent fans 2 need to be arranged side by side in close proximity, the length of the connector 1 is equal to the distance between the two fixed engagement positions when the two adjacent fans 2 are arranged side by side in close proximity.

[0055] When adjacent fans 2 need to be arranged side by side with a fixed distance between them, the length of the connector 1 is greater than the distance between two fixed engagement positions when the two adjacent fans 2 are arranged side by side and in close proximity. EXAMPLES

[0056] Example 7 This embodiment is an optimization based on any one of the above-mentioned embodiments 3 to 6.

[0057] The fan 2 is provided with a contact head, and a first contact point is located at the top of the contact head. The contact head is a spring ejection pin 12, and the spring ejection pin 12 can be compressed by the position of the first contact point mating with the second contact point, so as to ensure a close contact effect between the first contact point and the second contact point when the connector 1 is connected to the fan 2, thereby achieving a current-carrying effect and avoiding poor contact that would affect the use effect of the product.

[0058] As needs to be explained, the number of first contact points and the number of second contact points are set in a one-to-one correspondence, and the number of first contact points and the number of second contact points can be adaptively increased or decreased according to the needs of functional expansion of the fan 2.

[0059] For example, an RGB fan needs to have a motor power interface and an RGB light interface. Therefore, when this design is applied to an RGB fan, the numbers of the first contact points and the second contact points are both six, and the numbers of the first contact points and the second contact points for controlling the motor and the RGB light are three, respectively.

[0060] As needs to be explained, the spring ejection pin 12 may be provided at any position within the guide groove 7, but considering the adjustable spacing between adjacent fans 2 by the connector 1, preferably, the spring ejection pin 12 is provided at the outer end of the guide groove 7, so that when it is necessary to further realize adjustment to the spacing between adjacent fans 2 by adjusting the specific position of the fixed engagement position, effective contact between the second contact point of the connector 1 and the first contact point of the fan 2 can also be realized even if the spacing between the two adjacent fans 2 is maintained at the farthest distance. EXAMPLES

[0061] Example 8 This embodiment is an optimization based on the above embodiment 1 or 7.

[0062] In order to easily achieve effective contact between the second contact point and the first contact point, the connector 1 is provided with a contact surface, on which a conductive sheet 13 is provided, and the second contact point is located on the conductive sheet 13.

[0063] With such a design of the conductive sheet 13, the position of the second contact point is not limited to a fixed point, and a point-to-surface contact is made between the surface of the conductive sheet 13 and the first contact point, thereby improving the operational efficiency of the current connection between adjacent fans 2. Specifically, the conductive sheet 13 is a copper sheet. EXAMPLES

[0064] Example 9 As shown in Figures 1 to 15, the present invention further provides a magic link fan 2, which includes multiple fans 2 and a fan connection structure according to any one of Examples 1 to 8. With this design, the multiple fans 2 can achieve the current flow effect without the need for complicated wire connections, which can effectively improve the cleanliness of the structure in the fan installation environment and reduce the difficulty of wire management. EXAMPLES

[0065] Example 10 This embodiment is an optimization based on the above-mentioned embodiment 9.

[0066] In order to achieve a better connection effect, the upper and lower ends of adjacent fans 2 are both provided with fan connection structures.

[0067] In this technical solution, when multiple fans 2 need to be connected, the connector 1 can be simply pushed between two fans 2 to engage adjacent fans 2, realizing serial connection and power supply for multiple fans 2 without wires, and the structural design is simple, which greatly improves the convenience of serial connection and power supply between multiple fans 2 compared with the conventional design that requires multiple interfaces to be plugged in sequentially. By directly connecting multiple fans, it is possible to connect motors and RGB lights simultaneously, greatly reducing redundant wires and connector assemblies, and after connecting multiple fans in a row, it is only necessary to pull out wires through one fan connector at the end to connect the power supply and RGB interface of the motherboard.

[0068] Finally, as described above, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
