DETAILED DESCRIPTION

[0026] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0027] The heat-dissipating back brace 1 according to an embodiment of the present application is described below with reference to the accompanying drawings. Figures 1-4 The heat-dissipating back brace 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0028] The heat-dissipating back brace 1 according to an embodiment of the present application comprises a base body 11, a first quick release member, a second quick release member and a heat-dissipating body 16. The base body 11 is detachably connected with the counter member through the first quick release member, and the base body 11 is detachably connected with the heat-dissipating body 16 through the second quick release member. When the base body 11 connects the counter member and the heat-dissipating body 16, the heat-dissipating body 16 is in heat exchange contact with the counter member.

[0029] According to the heat dissipation back clamp 1, the base body 11 is connected with the second quick release member through the first quick release member, and heat exchange contact between the heat dissipation body 16 and the second quick release member is realized. At this time, the heat dissipation body 16 can be only detached from the base body 11 to realize charging, maintenance and other operations of the heat dissipation body 16, so that the heat dissipation body 16 is conveniently and quickly assembled and disassembled relative to the base body 11, and the probability of scratching and damaging the second quick release member relative to the base body 11 is effectively reduced.

[0030] It should be noted that the heat dissipation back clamp 1 can include a plurality of base bodies 11, and the first quick release member of different structures is arranged on each base body 11 to realize connection with more types of second quick release members, so that the heat dissipation body 16 is connected with the second quick release member to realize heat dissipation and cooling operations on more types of second quick release members, so that the application scene of the heat dissipation back clamp 1 is higher, and the cost is lower. The second quick release member includes but is not limited to a mobile phone, a tablet computer, a vehicle-mounted electronic product, an ice cup and the like.

[0031] In some embodiments, as shown in Figures 1-4 The base body 11 is provided with a mounting hole 111, and the heat dissipation body 16 includes a heat dissipation portion 161 which is detachably connected with the second quick release member to connect the heat dissipation body 16 to the base body 11. When the heat dissipation portion 161 is connected with the base body 11, the heat dissipation portion 161 passes through the mounting hole 111 and is in heat exchange contact with the second quick release member.

[0032] That is, the heat dissipation body 16 is connected with the second quick release member through the heat dissipation portion 161, and after connection, the heat dissipation portion 161 can pass through the mounting hole 111 from the side away from the second quick release member and be in heat exchange contact with the second quick release member, so as to effectively improve the heat exchange efficiency between the heat dissipation portion 161 and the second quick release member, and the cooling efficiency of the heat dissipation body 16 on the second quick release member is higher.

[0033] Specifically, the base body 11 is generally in a plate structure, and the mounting hole 111 penetrates the base body 11 along the thickness direction of the base body 11. After the heat dissipation portion 161 is inserted and matched with the mounting hole 111, the heat dissipation portion 161 and the base body 11 are relatively fixed in the radial direction of the mounting hole 111, so as to further improve the connection reliability of the heat dissipation body 16 and the base body 11. The heat dissipation body 16 further includes a refrigeration portion connected with the heat dissipation portion 161, and after the heat dissipation portion 161 passes through the mounting hole 111 and is in heat exchange contact with the second quick release member, the support portion abuts against the side of the base body 11 away from the second quick release member.

[0034] In some embodiments, the second quick-release member includes a plurality of first buckles 12 arranged on the inner wall surface of the mounting hole 111 and a plurality of second buckles 162 arranged on the outer peripheral wall surface of the heat dissipation portion 161, the plurality of first buckles 12 are arranged at intervals along the circumference of the inner wall surface of the mounting hole 111, and the plurality of second buckles 162 are arranged at intervals along the circumference of the outer peripheral wall surface of the heat dissipation portion 161. The first buckles 12 are configured to be buckled with the second buckles 162 to connect the heat dissipation portion 161 with the base body 11.

[0035] The connection of the heat dissipation portion 161 with the base body 11 is achieved by the buckling of the first buckles 12 with the second buckles 162, so that the heat dissipation body 16 is convenient to disassemble and assemble relative to the base body 11.

[0036] In some embodiments, the mounting hole 111 is a circular hole, the first buckles 12 include first protrusions 121 extending along the circumference of the mounting hole 111, and the second buckles 162 include second protrusions 1621, the length of the second protrusions 1621 in the circumference of the heat dissipation portion 161 is less than the interval of any two adjacent first protrusions 121 in the circumference of the mounting hole 111.

[0037] In this way, when the heat dissipation portion 161 passes through the mounting hole 111, the second protrusions 1621 pass through the gap between the adjacent two first protrusions 121 to ensure the smooth insertion of the heat dissipation portion 161. After the heat dissipation portion 161 is inserted in place, the heat dissipation portion 161 is rotated around the center axis of the mounting hole 111 to rotate the second protrusions 1621 to the side of the first protrusions 121 facing the opposite hand member, thereby completing the relative fixation of the base body 11 and the heat dissipation portion 161 in the axial direction of the mounting hole 111.

[0038] Specifically, as shown in Figures 2-4 the number of the first protrusions 121 and the second protrusions 1621 is four and one-to-one correspondence, the four first protrusions 121 are arranged at equal intervals along the circumference of the mounting hole 111, and the four second protrusions 1621 are arranged at equal intervals along the circumference of the heat dissipation portion 161. At this time, by moving the four second protrusions 1621 to the side of the corresponding first protrusions 121 facing the opposite hand member, the relative fixation of the base body 11 and the heat dissipation portion 161 in the axial direction of the mounting hole 111 is better ensured.

[0039] It should be noted that the second protrusions 1621 can also elastically deform the first protrusions 121 during the insertion of the heat dissipation portion 161 into the mounting hole 111 to pass through the first protrusions 121 and be located on the side of the first protrusions 121 facing the first reference surface.

[0040] In some embodiments, the inner wall surface of the mounting hole 111 is further provided with an annular protrusion 13 closer to the counterpiece than the first protrusion 121, the first protrusion 121 and the annular protrusion 13 are spaced apart along the axial direction of the mounting hole 111, and the second protrusion 1621 is clamped between the first protrusion 121 and the annular protrusion 13.

[0041] As shown in Figures 2-4 , that is, the annular protrusion 13 and the first protrusion 121 jointly achieve the axial limiting of the second protrusion 1621 in the mounting hole 111. At the same time, the partial heat dissipation part 161 is in clearance fit with the annular protrusion 13, thereby ensuring the coaxiality of the two and the radial limiting reliability of the base body 11 and the heat dissipation part 161 in the mounting hole 111.

[0042] In some embodiments, as shown in Figures 2-4 , the first clamping buckle 12 includes a first clamping protrusion 122 connected with the first protrusion 121 and the annular protrusion 13 and extending in the axial direction of the mounting hole 111, and the second clamping buckle 162 includes a second clamping protrusion 1622 extending in the protruding direction of the heat dissipation part 161 and connected with the second protrusion 1621.

[0043] When the second protrusion 1621 is inserted between the first protrusion 121 and the annular protrusion 13, the end of the first protrusion 121 away from the first clamping protrusion 122 is in abutment with the second clamping protrusion 1622, and the end of the second protrusion 1621 away from the second clamping protrusion 1622 is in abutment with the first clamping protrusion 122, thereby achieving the limiting of the heat dissipation part 161 and the base body 11 in one direction in the circumferential direction of the mounting hole 111, and avoiding the second protrusion 1621 from being separated from between the first protrusion 121 and the annular protrusion 13 to cause the axial limiting failure of the heat dissipation part 161 and the base body 11 in the mounting hole 111.

[0044] In some embodiments, as shown in Figure 2 , the first protrusion 121 has a first side surface facing the counterpiece and a first end surface perpendicular to the inner circumferential wall of the mounting hole 111, and a guide inclined surface 1211 is connected between the first side surface and the first end surface of the first protrusion 121.

[0045] That is, the clamping groove formed between the first protrusion 121 and the annular protrusion 13 is flared at the end of the first protrusion 121 away from the first clamping protrusion 122, and when the heat dissipation part 161 rotates around the central axis of the mounting hole 111, the second protrusion 1621 is more easily inserted into the clamping groove formed between the first protrusion 121 and the annular protrusion 13, thereby effectively achieving the rapid assembly of the heat dissipation part 161 and the base body 11.

[0046] Specifically, the end of the second protruding strip 1621 away from the second clamping protrusion 1622 is also chamfered to reduce the width of the end of the second protruding strip 1621, thereby further reducing the difficulty of inserting the second protruding strip 1621 between the first protruding strip 121 and the annular protruding strip 13.

[0047] In some embodiments, the second quick release member further comprises a plurality of third clamping buckles 14 arranged on the inner wall surface of the mounting hole 111, and a plurality of fourth clamping buckles 163 arranged on the outer circumferential surface of the heat dissipation portion 161. The third clamping buckles 14 are located between two adjacent first clamping buckles 12 and protrude from the inner wall surface of the mounting hole 111. The fourth clamping buckles 163 are located between two adjacent second clamping buckles 162 and protrude from the outer circumferential wall surface of the heat dissipation portion 161. When the heat dissipation portion 161 is connected to the base body 11, the third clamping buckles 14 and the fourth clamping buckles 163 limit each other.

[0048] The third clamping buckles 14 and the fourth clamping buckles 163 limit each other in the circumferential direction of the mounting hole 111. In combination with the arrangement of the first clamping protrusion 122 and the second clamping protrusion 1622, the relative fixation of the heat dissipation portion 161 and the base body 11 in the circumferential direction of the mounting hole 111 is completed, thereby ensuring the connection reliability of the heat dissipation body 16 and the base body 11.

[0049] Specifically, the third clamping buckles 14 and the fourth clamping buckles 163 are both four. The four third clamping buckles 14 are arranged at equal intervals in the circumferential direction of the mounting hole 111. The four third clamping buckles 14 and the four first clamping buckles 12 are alternately arranged in the circumferential direction of the mounting hole 111. Thus, by limiting each other through the four fourth clamping buckles 163 and the corresponding third clamping buckles 14, the positioning reliability of the base body 11 and the heat dissipation body 16 in the circumferential direction of the mounting hole 111 is better ensured.

[0050] In some embodiments, as shown in Figure 2 and Figure 3 The mounting hole 111 is a circular hole. The third clamping buckle 14 comprises a third clamping protrusion 141, and the fourth clamping buckle 163 comprises a fourth clamping protrusion 1631. The inner wall surface of the mounting hole 111 is provided with a strip-shaped hole 112 extending in the circumferential direction of the mounting hole 111. The strip-shaped hole 112 and the third clamping protrusion 141 are arranged in the axial direction of the mounting hole 111.

[0051] Thus, when the heat dissipation part 161 is inserted into the mounting hole 111 and rotates around the axis of the mounting hole 111, the fourth clamping protrusion 1631 deforms and passes over the third clamping protrusion 141, so that the fourth clamping protrusion 1631 is limited on the other side of the third clamping protrusion 141, and the second protrusion 1621 and the first protrusion 121 are buckled in place, completing the relative fixation of the base body 11 and the heat dissipation body 16 in the circumferential direction of the mounting hole 111. The provision of the strip-shaped hole 112 reduces the structural strength at the third clamping protrusion 141, so that when the fourth clamping buckle 163 presses the third clamping protrusion 141 in the circumferential direction of the mounting hole 111, the deformation of the third clamping protrusion 141 is more difficult, and the clamping difficulty of the third clamping protrusion 141 and the fourth clamping protrusion 1631 is lower.

[0052] Specifically, the third clamping protrusion 141 and the fourth clamping protrusion 1631 both extend in the axial direction of the mounting hole 111, and the third clamping protrusion 141 is provided with a strip-shaped hole 112 on both sides in the axial direction of the mounting hole 111.

[0053] In some embodiments, as shown in Figure 2 and Figure 3 The third clamping protrusion 141 extends in the axial direction of the mounting hole 111, and the size of the third clamping protrusion 141 in the circumferential direction of the mounting hole 111 gradually decreases in the radial direction outward of the mounting hole 111.

[0054] Thus, when the fourth clamping protrusion 1631 presses the first clamping protrusion 122 to deform, the deformation of the first clamping protrusion 122 is more difficult, and the disassembly efficiency of the heat dissipation body 16 and the base body 11 is higher.

[0055] Specifically, in the projection plane perpendicular to the axial direction of the mounting hole 111, the projection of the first clamping protrusion 122 is generally triangular or isosceles trapezoidal.

[0056] It should be noted that the second quick release member can also be an internal thread provided on the inner wall surface of the mounting hole 111, and the outer circumferential surface of the heat dissipation part 161 is provided with an external thread, and through the cooperation of the external thread and the internal thread, the quick disassembly of the heat dissipation part 161 on the base body 11 can also be achieved.

[0057] In some embodiments, the first quick release member includes a clamping assembly 15 and / or a magnetic member.

[0058] That is, the base body 11 can be clamped and fixed on the opposite hand member by the clamping assembly 15, or can be adsorbed and fixed on the opposite hand member by the magnetic member, and the disassembly between the base body 11 and the opposite hand member is convenient.

[0059] Specifically, when the first quick release member is the clamping assembly 15, the clamping assembly 15 is arranged on the side of the base body 11 facing the opposite hand member, and the clamping range of the clamping assembly 15 is 58mm-88mm, so that it can adapt to more sizes of the opposite hand member.

[0060] When the first quick release member is the magnetic attraction member, the base body 11 is provided with a plurality of installation cavities surrounding the installation holes 111, and the magnetic attraction member comprises a plurality of magnets arranged along the circumferential direction of the installation holes 111.

[0061] When the first quick release member is the magnetic attraction member, the heat dissipation back clip 1 can be magnetically connected with the opposite hand member (for example, a mobile phone), so that the heat dissipation back clip 1 and the opposite hand member can be quickly and conveniently disassembled and assembled.
