Description
HEAT DISSIPATING DISK STRUCTURE
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a brake disk structure, and more particularly to a heat dissipating disk structure provided with both heat dissipation capability and convenient assembly.
(b) Description of the Prior Art
Disk brakes are installed on the wheels of all conventional vehicles, and when the driver brakes the vehicle, brake linings are used to clamp onto the disk brakes, which converts kinetic energy of the vehicle into heat energy through frictional resistance between the brake linings and the disk brakes. The disk brakes are then used to dissipate the heat energy to the ambient air, thereby achieving functional reuse of the brakes. If the speed of heat dissipation from the disk brakes is too slow, then the brake system is unable to smoothly convert kinetic energy into heat energy, which causes failure in brake effectiveness of the vehicle. Hence, a key point for improvement of the disks is how to increase heat dissipation efficiency. An example of a brake disk structure of the prior art is Taiwan patent No. M490441 of a disk brake approved by the Taiwan Patent Office on 21 November, 2014, in which a main body comprises a mounting portion assembled to one side of a hub disk, a friction ring portion corresponding to a brake caliper, and a plurality of connecting ribs connected between the mounting portion and the friction ring portion. Every two adjacent connecting ribs and the friction ring portion enclose a ring type hole, and at least one nose end of each of the holes is provided with an embedding slot. Moreover, the embedding slot does not completely go around the at least one nose end of the ring type hole. A plurality of cooling fins are respectively embedded and fixed in the circumferential sides of the embedding slots. Each of the cooling fins is provided with a plurality of fixing portions connected to the surface of the cooling fin to form an integral body therewith, which are used to fixedly rivet the cooling fin to the embedding slot. In addition, a plurality of wind guide protruding pieces are disposed at intervals on each of the plurality of cooling fins, and each of the wind guide protruding pieces is provided with a wind guide hole. The wind guide hole comprises an inflow end and an outflow end, wherein the outflow end is orientated toward the direction of the friction ring portion. From the aforementioned detailed description of the structure of the prior art it is not difficult to see that there still exists several shortcomings, primary reasons for which are outlined below: Although the cooling fins are able to increase the heat dissipation effectiveness of the main body, however, because of the circumferential side embedded method used to fix the cooling fins in the embedding slots of the main body, and the plurality of fixing portions connected to the surface of each of the cooling fins to form an integral body therewith and fixedly riveted to each of the embedding slots, thus, additional riveting processes are required in order to fix the cooling fins to the main body. Accordingly, the riveting steps will increase processing time of the disc as well as cost, and is the technical problem the present invention intends to resolve.
In light of this, the inventor of the present invention, having accumulated many years of experience in manufacturing development and the design of related products, and after detailed addition to the design and careful evaluation of the aforementioned objects, finally achieved a heat dissipating disk structure having true practicability as disclosed in the present invention.
SUMMARY OF THE INVENTION
The technical problem that the present invention intends to resolve involves solving the aforementioned shortcomings existent in the prior art and provide a heat dissipating disk structure.
An outer disk of a heat dissipating disk structure of the present invention assumes a ring shape and forms a caliper holding portion. A plurality of hollowed-out holes are configured in the caliper holding portion of the outer disk, and the hollowed-out holes increase the heat dissipation effectiveness of the outer disk. Moreover, a plurality of connecting portions extend at equal intervals from the inner edge of the caliper holding portion of the outer disk toward the center, and a clasp groove is indentedly provided along the inner edge of the caliper holding portion in the area between each pair of the connecting portions of the outer disk. Furthermore, each of the clasp grooves are provided with a dispose opening adjacent to the two ends of each pair of the connecting portions. In addition, a lesser curved segment is formed at one end of each of the clasp grooves of the outer disk, and a greater curved segment is formed at the other end of each of the clasp grooves. The plurality of cooling fins respectively slide into the clasp grooves along the dispose openings thereof, however, the cooling fins need to be first respectively disposed into the lesser curved segments at an oblique angle, and then disposed into the greater curved segments, thereby enabling the edges of the cooling fins to be completely embedded in the clasp grooves. Furthermore, a plurality of protruding portions are formed on the surface of each of the cooling fins, and the protruding portions are used to increase the area of contact with the air. An inner disk of the heat dissipating disk structure assumes a radial form, and a plurality of connecting strips protrude from the outer edge. The inner disk is disposed in the center area of the outer disk so that the connecting strips are directly opposite the connecting portions of the outer disk, and fixing members are used to form riveted connections between the connecting strips and the connecting portions. Moreover, the connecting strips are installed to block the dispose openings of the clasp grooves.
to A primary object of the present invention lies in indentedly providing a clasp groove along the inner edge of the caliper holding portion in the area between each pair of the connecting portions of the outer disk, thereby enabling an equal number of the cooling fins to be disposed into the clasp grooves from the area of the dispose openings. Furthermore, the inner disk is disposed in the center area of the outer disk, and the connecting strips of the inner disk are aligned with the connecting portions of the outer disk. Fixing members are then used to form riveted connections between the connecting portions and the connecting strips, thereby achieving rapid assembly of the outer disk, the cooling fins, and the inner disk. At the same time, the connecting strips of the inner disk are used to block the areas of the dispose openings of the clasp grooves, thereby preventing the cooling fins from separating from the clasp grooves, and eliminating the need to use additional machine processing, including screw locking, riveting, or welding on the cooling fins while still enabling stable connection to the outer disk. Accordingly, the function to reduce costs is achieved through a simplified assembly procedure.
A second principal object of the present invention lies in enabling each of the cooling fins to slide in along the respective dispose openings of the clasp grooves, however, the cooling fins need to be first disposed into the lesser curved segment at an oblique angle, and then disposed into the greater curved segment, thus the cooling fins can only be extracted at the same oblique angle. Accordingly, the structure forms a simple and easy limiting displacement assembly of the cooling fins within the clasp grooves, while preventing the cooling fins from dropping out of the outer disk by themselves when repeatedly installing the plurality of cooling fins. Hence, the structure makes it much easier to proceed with the assembly procedure.
Other objects, advantages, and original characteristics of the present invention from the following detailed description and related drawings will be made clearer.
To enable a further understanding of said objectives and the technological methods of the invention herein, a brief description of the drawings is provided below followed by a detailed description of the preferred embodiments.

Referring first to the drawings depicted in FIGS. 1 to 4, which show a heat dissipating disk structure comprising: an outer disk 10, a plurality of 20 cooling fins 20, and an inner disk 30. The outer disk 10 assumes a ring shape to form a caliper holding portion 11. The caliper holding portion 11 of the outer disk 10 is provided with a plurality of hollowed-out holes 12, and the hollowed-out holes 12 are used to increase the heat dissipation effectiveness of the outer disk 10. Moreover, a plurality of connecting portions 13 extend at equal intervals from the inner edge of the caliper holding portion 11 of the outer disk 10 toward the center. Furthermore, a clasp groove 14 is indentedly provided along the inner edge of the caliper holding portion 11 between each pair of the connecting portions 13 of the outer disk 10. In addition, each of the clasp grooves 14 is configured with dispose openings 141 adjacent to the two ends of each pair of the connecting portions 13. A lesser curved segment 142 is further formed at one end of each of the clasp grooves 14 of the outer disk 10, and a greater curved segment 143 is formed at the other end of each of the clasp grooves 14. The plurality of cooling fins 20 respectively slide into the clasp grooves 14 along the dispose openings 141 thereof, however, the cooling fins 20 need to be first respectively disposed into the lesser curved segments 142 at an oblique angle, and then disposed into the greater curved segments 143, thereby only enabling the cooling fins 20 to be extracted at the same oblique angle. Accordingly, such a structure forms a simple and easy limiting displacement assembly of the cooling fins 20 within the clasp grooves 14, enabling the edges of the cooling fins 20 to be completely embedded in the clasp grooves 14. Furthermore, a plurality of protruding portions 21 are formed on the surface of each of the cooling fins 20, and the protruding portions 21 are used to increase the area of contact with the air. The inner disk 30 assumes a radial form, and a plurality of connecting strips 31 protrude from the outer edge thereof. The inner disk 30 is disposed in the center area of the outer disk 10, with the connecting strips 31 disposed so as to be directly opposite the connecting portions 13 of the outer disk 10. Furthermore, riveted connections are formed between the connecting strips 31 and the connecting portions 13 using fixing members 32. In addition, the connecting strips 31 are installed so as to block the dispose openings 141 of the clasp grooves 14, thereby fixedly positioning the cooling fins 20 within the clasp grooves 14, and providing both heat dissipating capability and convenient assembly.
Regarding structural assembly of the present invention, referring again to the drawings depicted in FIGS. 1 to 4, the area between each pair of the connecting portions 13 of the outer disk 10 along the inner edge of the caliper holding portion 11 is indentedly provided with the clasp groove 14, which enable an equal number of the cooling fins 20 to be respectively disposed into the clasp grooves 14 from the areas of the dispose openings 141. Moreover, through the curvature design of the two ends of each of the clasp grooves 14, one end of each of the cooling fins 20 is first respectively disposed at an oblique angle into the lesser curved segment 142 at one end of the clasp groove 14, and then the other end of the the cooling fin 20 is disposed into the greater curved segment 143 of the clasp groove 14, thereby achieving a simple and easy limiting displacement assembly of the cooling fins 20 into the outer disk 10 and preventing the cooling fins 20 from dropping out from the outer disk 10 by themselves when repeatedly installing the plurality of cooling fins 20. Furthermore, the inner disk 30 is disposed in the center area of the outer disk 10, and the connecting strips 31 of the inner disk 30 are aligned with the connecting portions 13 of the outer disk 10, the fixing members 32 are then used to form riveted connections between the connecting portions 13 and the connecting strips 31, thereby enabling rapid assembly of the outer disk 10, the cooling fins 20, and the inner disk 30. In addition, the connecting strips 31 of the inner disk 30 block the areas of the dispose openings 141 of the clasp grooves 14, which prevents the cooling fins 20 from separating from the clasp grooves 14, and eliminates the need to use additional machine processing including screw locking, riveting, or welding on the cooling fins 20 while still achieving a stable connection between the cooling fins 20 and the outer disk 10. Accordingly, the present invention achieves the function to reduce costs through a simplified assembly procedure. In addition, when using the present invention, the caliper holding portion 11 of the outer disk 10 is used to enable clamping of brake calipers (not shown in the drawings), which causes the conversion of kinetic energy into heat energy through frictional resistance, and the outer disk 10 is then used to dissipate the heat energy to the ambient air, thereby achieving functional reuse of the brakes. The outer disk 10 is additionally able to guide heat energy to the cooling fins 20, and the cooling fins 20 and the protruding portions 21 on the surfaces thereof increase the area of contact with the air, which further augments the heat dissipation efficiency of the outer disk 10.
thereby providing both heat dissipating capability and convenient assembly.
In conclusion, the present invention has assuredly achieved a breakthrough in structural design, is provided with improved 20 effectiveness, and also achieves industrial functionality and advancement. Moreover, no similar products have been seen in any publication or in the market. The present invention is thus provided with undoubted originality. Hence, the incomparable advancement of the present invention clearly complies with the essential elements as required for a new patent application. Accordingly, a new patent application is proposed herein.
It is of course to be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
