[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to an assembly structure for a radiator and a guide rail, and an assembly structure for a relay. Background Technology

[0002] The relay body is usually equipped with a heat sink for ventilation and heat dissipation. After the relay body and the heat sink are fixedly installed, a mounting structure is usually set on the side of the heat sink. The relay is securely installed by fixing it to the guide rail through the mounting structure.

[0003] The existing relay mounting structure is a single unit with poor vibration resistance, making it prone to damage. When some parts are worn or damaged, the entire unit needs to be replaced, which is not conducive to cost savings. Utility Model Content

[0004] The purpose of this utility model is to overcome at least one defect of the prior art and provide an assembly structure for a heat sink and guide rail, as well as an assembly structure for a relay, that saves on installation structure costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this application provides an assembly structure for a heat sink and a guide rail, including a heat sink, wherein the heat sink is connected to a mounting structure for connecting with the guide rail.

[0007] The radiator includes a sliding groove, and the mounting structure includes a first sliding member and a second sliding member installed in the sliding groove. The first sliding member is provided with a first limiting member, and the second sliding member is provided with a second limiting member. An elastic member is provided between the first sliding member and the second sliding member. The elastic member drives the first sliding member or the second sliding member to move in a straight line, so that the first sliding member and the second sliding member are brought closer together, and the first limiting member and the second limiting member clamp the guide rail.

[0008] In one possible implementation, the first slider and the second slider have the same structure, and / or the first slider and the second slider are metal sliders.

[0009] In one possible implementation, the first slider has a first limiting portion at its end and a first mounting notch on the side adjacent to the first limiting portion; the second slider has a second limiting portion at its end and a second mounting notch on the side adjacent to the second limiting portion; the first limiting portion extends into the second mounting notch; the second limiting portion extends into the first mounting notch; and the elastic member is located between the first limiting portion and the second limiting portion.

[0010] In one possible implementation, the first limiting part is provided with a fixed protrusion facing the second limiting part, and the second limiting part is provided with a fixed protrusion facing the first limiting part. The elastic element is a compression spring, and the two ends of the compression spring are respectively sleeved on the two fixed protrusions.

[0011] In one possible implementation, the first limiting part has a first limiting surface on the side opposite to the first mounting notch, the second mounting notch has a second limiting surface, the second limiting part has a third limiting surface on the side opposite to the second mounting notch, and the first mounting notch has a fourth limiting surface. The elastic element can drive the first limiting surface and the second limiting surface to abut against each other, and the third limiting surface and the fourth limiting surface to abut against each other.

[0012] In one possible implementation, the first slider and the second slider are flat plate structures, the first limiting member is perpendicular to the first slider, and the second limiting member is perpendicular to the second slider; and / or, the first limiting member and the second limiting member are both hooks, the first hook notch of the first limiting member is opposite to the second hook notch of the second limiting member, and both sides of the guide rail are engaged in the first hook notch and the second hook notch.

[0013] In one possible implementation, two opposing limiting walls are provided on both sides of the sliding groove in the width direction, and two limiting grooves are provided between the two limiting walls and the bottom surface of the sliding groove. The two sides of the guide rail are located in the two limiting grooves, and the two limiting walls restrict the installation structure from disengaging from the sliding groove.

[0014] In one possible implementation, the first slider and the second slider are provided with screw fixing holes, and the first slider is fixed to the heat sink by a screw passing through the screw fixing hole, or the second slider is fixed to the heat sink by a screw passing through the screw fixing hole.

[0015] And / or, the end of the first slider away from the second slider and the end of the second slider away from the first slider are provided with screw holes, the screw holes being used for connecting and fixing the first slider or the first slider to an external device, the screw holes being flush with the top of the first limiting member and the top of the second limiting member.

[0016] In one possible implementation, a tool operating part is provided at the end of the first slider away from the second slider, and / or, a tool operating part is provided at the end of the second slider away from the first slider, the tool operating part being used to drive the first slider or the second slider to move.

[0017] Secondly, this application also provides a relay assembly structure, including the heat sink and guide rail assembly structure described in any of the above claims, and a relay body, wherein the heat sink is disposed at the bottom of the relay body, and the mounting structure is disposed at the bottom of the heat sink.

[0018] Compared to existing technologies, this application provides a sliding groove on the radiator, with the first and second sliding members of the mounting structure installed within the sliding groove. An elastic member is provided between the first and second sliding members, which can drive the first and second sliding members closer together, reducing the distance between the first and second limiting members. This allows the first and second limiting members to clamp the guide rail, thus fixing the relay. If either the first or second sliding member is damaged, one can be replaced while the other continues to be used, saving production costs.

[0019] Furthermore, both the first and second sliding members are metal sliding members. Metal materials offer high structural strength, robustness, durability, and strong vibration resistance.

[0020] Furthermore, the first and second sliding components have the same structure, which saves process steps and improves production efficiency.

[0021] In addition, the first limiting part extends into the second mounting notch, and the second limiting part extends into the first mounting notch. The first fixing part of the first limiting part and the second fixing part of the second limiting part are opposite to each other. Pulling the first sliding member or the second sliding member will cause the first fixing part and the second fixing part to abut against each other, which can limit the maximum distance between the first limiting member and the second limiting member and prevent the first sliding member or the second sliding member from coming out from one end of the sliding groove in the length direction, resulting in a better operating experience.

[0041] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0042] An assembly structure for a relay includes a relay body 1, a heat sink 2 at the bottom of the relay body 1, the relay body 1 including a relay housing and a control board assembly disposed within the relay housing, the control board assembly having two terminals for power connection; the heat sink 2 including a heat sink housing 21 and a plurality of heat sink fins 22 arranged parallel and spaced within the heat sink housing 21 for ventilation and heat dissipation of the relay.

[0043] like Figures 1-3 As shown, this application provides an assembly structure for a heat sink and a guide rail, including a heat sink 2, the bottom of which is connected to a mounting structure 3 for connecting with the guide rail.

[0044] The relay body 1 and the heat sink 2, and the heat sink 2 and the mounting structure 3 can be fixedly installed by means of, but not limited to, snap-fit ​​structure, screw, welding, or riveting.

[0045] like Figures 1-3As shown, the mounting structure 3 is mounted on the radiator 2. The radiator 2 includes a sliding groove 23. The mounting structure 3 includes a first sliding member 31 and a second sliding member 32 mounted in the sliding groove 23. The first sliding member 31 is provided with a first limiting member 311, and the second sliding member 32 is provided with a second limiting member 321. An elastic member 4 is provided between the first sliding member 31 and the second sliding member 32. The elastic member 4 drives the first sliding member 31 or the second sliding member 32 to move in a straight line, so that the first sliding member 31 and the second sliding member 32 move closer together, reducing the distance between the first limiting member 311 and the second limiting member 321, so that the first limiting member 311 and the second limiting member 321 clamp the guide rail. The elastic member 4 can be a compression spring, a tension spring, a torsion spring, or a spring, etc. By setting a sliding groove 23 on the radiator 2, the mounting structure 3 is divided into a first sliding member 31 and a second sliding member 32. The first sliding member 31 and the second sliding member 32 are installed in the sliding groove 23. An elastic member 4 is set between the first sliding member 31 and the second sliding member 32, which can drive the first sliding member 31 and the second sliding member 32 to move closer together, reducing the distance between the first limiting member 311 and the second limiting member 321. This allows the first limiting member 311 and the second limiting member 321 to clamp the guide rail, so that the relay can be fixed. If the first sliding member 31 or the second sliding member 32 is damaged, one of them can be replaced and the other can continue to be used, saving production costs.

[0046] Preferably, the first slider 31 has a first connecting end and a first operating end at both ends, and the second slider 32 has a second connecting end and a second operating end at both ends. The first connecting end and the second connecting end are opposite to each other, and the elastic member 4 is connected between the first connecting end and the second connecting end. The first operating end is away from the second operating end.

[0047] In one embodiment, the elastic element 4 is a tension spring, which generates tension between the first connecting end and the second connecting end, driving the first sliding element 31 and the second sliding element 32 to move closer together; in another embodiment, the elastic element 4 is a compression spring, which generates thrust between the first connecting end and the second connecting end, driving the first sliding element 31 and the second sliding element 32 to move closer together.

[0048] In a preferred embodiment of this application, the elastic element 4 is a compression spring.

[0049] like Figure 2 and Figure 3As shown, the first connecting end includes a first limiting part 312 located at the end of the first sliding member 31, and a first mounting notch 313 is provided on the side adjacent to the first limiting part 312. The second connecting end includes a second limiting part 322 located at the end of the second sliding member 32, and a second mounting notch 323 is provided on the side adjacent to the second limiting part 322. When the first sliding member 31 and the second sliding member 32 are installed, the first connecting end and the second connecting end are arranged crosswise. The first limiting part 312 extends into the second mounting notch 323, and the second limiting part 322 extends into the first mounting notch 313. The elastic member 4 is connected between the first limiting part 312 and the second limiting part 322. The first limiting part 312 is provided with a first fixing part 314 in the direction of the second limiting part 322, and the second limiting part 322 is provided with a second fixing part 324 in the direction of the first limiting part 312. The two ends of the elastic member 4 are respectively connected to the first fixing part 314 and the second fixing part 324. The first fixing part 314 and the second fixing part 324 are used to fix the elastic member 4. The first fixing part 314 and the second fixing part 324 can be fixing protrusions, with the two ends of the compression spring respectively sleeved on the two fixing protrusions. Of course, the first fixing part 314 and the second fixing part 324 can also be fixing grooves, with the two ends of the compression spring respectively located in the two fixing grooves.

[0050] In this embodiment, the first limiting part 312 extends into the second mounting notch 323, and the second limiting part 322 extends into the first mounting notch 313. The first fixing part 314 of the first limiting part 312 and the second fixing part 324 of the second limiting part 322 are opposite to each other. Pulling the first sliding member 31 or the second sliding member 32 causes the first fixing part 314 and the second fixing part 324 to abut against each other, which can limit the maximum distance between the first limiting member 311 and the second limiting member 321, and prevent the first sliding member 31 or the second sliding member 32 from coming out of one end of the sliding groove 23 in the length direction, resulting in a better operating experience.

[0051] In another embodiment, the elastic element 4 is a tension spring, and the first fixing part 314 and the second fixing part 324 can be fixing holes, with both ends of the elastic element 4 connected to the two fixing holes respectively.

[0052] Furthermore, such as Figure 3As shown, the first limiting part 312 has a first limiting surface 315 on the side opposite to the first mounting notch 313, the second mounting notch 323 has a second limiting surface 316, the second limiting part 322 has a third limiting surface 317 on the side opposite to the second mounting notch 323, and the first mounting notch 313 has a fourth limiting surface 318. The elastic member 4 can drive the first limiting surface 315 and the second limiting surface 316 to abut against each other, and the third limiting surface 317 and the fourth limiting surface 318 to abut against each other, thereby limiting the minimum distance between the first limiting member 311 and the second limiting member 321.

[0053] Preferred, such as Figure 3 As shown, the first slider 31 and the second slider 32 are flat plate structures. The first limiting member 311 is perpendicular to the first slider 31, and the second limiting member 321 is perpendicular to the second slider 32. In other embodiments, the first limiting member 311 and the second limiting member 321 may also be inclined and not strictly perpendicular.

[0054] Furthermore, such as Figures 1-3 As shown, both the first limiting member 311 and the second limiting member 321 are hooks. The first hook notch 3111 of the first limiting member 311 is opposite to the second hook notch 3211 of the second limiting member 321. The guide rail is limited between the first sliding member 31 and the second sliding member 32. Both sides of the guide rail are locked in the first hook notch 3111 and the second hook notch 3211.

[0055] Furthermore, such as Figure 3 As shown, the first sliding member 31 and / or the second sliding member 32 are provided with a first fixing structure 33, which is used to fix the first sliding member 31 or the second sliding member 32 to the heat sink 2. Further, in this embodiment, the first fixing structure 33 is a screw fixing hole, whereby the first sliding member 31 is fixed to the heat sink 2 by a screw passing through the screw fixing hole, or the second sliding member 32 is fixed to the heat sink 2 by a screw passing through the screw fixing hole. In other embodiments, the first fixing structure 33 can also be a snap-fit ​​structure that is snap-fitted to the heat sink 2.

[0056] Furthermore, such as Figure 2 As shown, two opposing limiting walls 231 are provided on both sides of the sliding groove 23 in the width direction. There are two limiting grooves between the two limiting walls 231 and the bottom surface of the sliding groove 23. The two sides of the guide rail are located in the two limiting grooves. The two limiting walls 231 restrict the installation structure 3 from being dislodged from the sliding groove 23.

[0057] During installation, the first sliding member 31 and the second sliding member 32 are installed into the sliding groove 23 of the radiator 2 along the length of the sliding groove 23. The first sliding member 31 and the second sliding member 32 are inserted from both ends of the sliding groove 23. The two limiting walls 231 on both sides of the sliding groove 23 restrict the first sliding member 31 and the second sliding member 32 to slide only along the length of the sliding groove 23. One sliding member is fixed to the radiator 2 by the first fixing structure 33, while the other sliding member can slide within the sliding groove 23. For example, the first sliding member 31 is fixed to the radiator 2, and the second sliding member 32 is driven to move away from the first sliding member 31. This causes the elastic member 4 to store energy. After the distance between the first limiting member 311 and the second limiting member 321 increases, the guide rail is installed between the first limiting member 311 and the second limiting member 321. The elastic member 4 releases energy, driving the first sliding member 31 and the second sliding member 32 to move towards each other, causing the first limiting member 311 and the second limiting member 321 to move closer to the clamping guide rail. This fixes the mounting structure 3 to the guide rail. Furthermore, users can choose to fix the first sliding member 31 to the heat sink 2 or the second sliding member 32 to the heat sink 2 as needed.

[0058] Preferred, such as Figure 3 As shown, the first operating end of the first sliding member 31 is provided with a tool operating part 34, and / or the second operating end of the second sliding member 32 is provided with a tool operating part 34. The tool operating part 34 is used to drive the first sliding member 31 or the second sliding member 32 to move within the sliding groove 23, thereby increasing the distance between the first limiting member 311 and the second limiting member 321, so that the relay can be removed from the guide rail. In a preferred embodiment of this application, the tool operating part 34 is a hole-like structure. When disassembling the relay, a screwdriver can be inserted into the hole-like structure of the tool operating part 34 to move the first sliding member 31 or the second sliding member 32. Of course, in other embodiments, the tool operating part 34 can also be a groove or a protrusion, which is also possible.

[0059] Furthermore, such as Figure 3 As shown, a fastening part 35 is provided at the first operating end of the first sliding member 31 and / or the second operating end of the second sliding member 32. The fastening part 35 is used to connect and fix the first sliding member 31 or the first sliding member 31 and the external device, which can prevent misalignment between the mounting structure 3 and the external device after installation. In a preferred embodiment of this application, the fastening part 35 includes screw holes, and the screw passes through the screw holes to fix it to the external device, thereby improving the firmness. Of course, in other embodiments, the fastening part 35 can also be a snap-fit ​​structure that snaps into the external device.

[0060] Furthermore, such as Figure 3As shown, the screw holes are flush with the top of the first limiting member 311 and the top of the second limiting member 321. After the fastening part 35 is fixed to the external device, the top of the first limiting member 311 and the top of the second limiting member 321 abut against the external device, resulting in better stability.

[0061] Preferred, such as Figure 3 As shown, the first slider 31 and the second slider 32 have the same structure and are centrally symmetrical. The first slider 31 can be used as the second slider 32 after rotating 180 degrees, saving process steps and improving production efficiency. Only the first slider 31 needs to be manufactured, which can then be used for both the first and second sliders 32. Of course, in other embodiments, the structures of the first slider 31 and the second slider 32 may not be exactly the same.

[0062] Preferably, the first slider 31 and the second slider 32 are metal sliders. Metal materials have high structural strength, are robust, not easily damaged, and have strong vibration resistance. As other embodiments, the first slider 31 and the second slider 32 may also be, but are not limited to, made of plastic.

[0063] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "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 during use. They are only for ease of description and do not indicate that the device or component referred to must have a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating relative importance.

[0064] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
