Description

Technical Field

[0001] This application relates to the field of electrical device technology, and in particular to clamping assemblies and converters. Background Technology

[0002] In applications such as high and low voltage systems for electric vehicles, converters (such as DC / DC converters) play an important role.

[0003] Some components inside the converter are characterized by high power consumption and large heat generation. To ensure the converter's performance and lifespan, adequate heat dissipation is necessary for these components. Since some converters are relatively small, using the housing for component cooling has become a common method. When using the housing for cooling, a tight contact between the components and the housing is required to ensure effective heat dissipation. Therefore, a clamping structure is needed to achieve this tight contact between high-power components and the housing.

[0004] Different components have different shapes and sizes. Therefore, during the installation process, the clamping structure is subjected to different reaction forces from components of different shapes and sizes, which can easily cause misalignment, making installation difficult, inconvenient for accurate positioning, and easy to damage the clamping components. Utility Model Content

[0005] Based on this, in order to solve the problem that the clamping structure is prone to displacement during installation, a clamping component and a converter are provided.

[0006] This application provides a clamping assembly applied to a converter. The converter includes a housing and a component to be clamped. The housing includes a fixed base and a mounting base, which are arranged along a first direction. The component to be clamped is located on the side of the fixed base near the mounting base. The clamping assembly includes: a positioning structure slidably connected to the mounting base along the first direction; a clamping structure fixedly connected to the positioning structure, with one side of the clamping structure in the first direction contacting and engaging with the component to be clamped; and a locking structure connected to both the positioning structure and the mounting base, for locking the relative positions of the positioning structure and the mounting base.

[0007] According to one embodiment of this application, the mounting base is provided with two slide rails, and a groove extending along the first direction is formed between the two slide rails. The positioning structure is located in the groove, and the two sides of the positioning structure respectively slide in contact with the slide rail on the corresponding side.

[0008] According to one embodiment of this application, the locking structure includes: at least one snap-fit ​​protrusion fixedly connected to the positioning structure, and at least one slide rail having a slot on the side facing the positioning structure, wherein the snap-fit ​​protrusion engages with the slot to limit the movement of the positioning structure and the slide rail along the first direction.

[0009] According to one embodiment of this application, the positioning structure includes: a positioning part connecting the pressing structure and the locking structure; a pair of sliding parts disposed on both sides of the positioning part and located in the sliding groove, the sliding parts extending along the first direction, one end of the sliding part along the first direction being fixedly connected to the positioning part, and the other end having a gap with the positioning part to form a first groove between the sliding part and the positioning part, and the snap-fit ​​protrusion being located on the side of the sliding part away from the first groove.

[0010] According to one embodiment of this application, the end of the sliding portion facing the pressing structure is fixedly connected to the positioning portion, and the snap-fit ​​protrusion is located at the end of the sliding portion away from the pressing structure.

[0011] According to one embodiment of this application, the positioning structure is provided with a first positioning hole, the first positioning hole penetrates the positioning structure and extends along the first direction; the mounting base is provided with a guide post, the guide post being slidably disposed in the first positioning hole; the locking structure includes a first threaded component, the first threaded component being threadedly connected to the guide post, the head of the first threaded component being located on the side of the positioning structure opposite to the mounting base.

[0012] According to one embodiment of this application, the positioning structure is provided with a second positioning hole, which is a circular through hole; the locking structure includes a second threaded component, which passes through the second positioning hole and is threadedly connected to the mounting base to lock the relative position of the positioning structure and the mounting base.

[0013] According to one embodiment of this application, the pressing structure is provided with at least one pressing protrusion, and the pressing structure contacts and engages with the part to be pressed through the pressing protrusion.

[0014] According to one embodiment of this application, the pressing structure includes a connecting portion and a plurality of elastic portions. The connecting portion is fixedly connected to the positioning structure and the plurality of elastic portions respectively. A second groove is formed between adjacent elastic portions, and the pressing protrusion is located on the elastic portion.

[0015] This application also provides a converter including the clamping assembly of the above embodiments.

[0016] The aforementioned clamping assembly and converter have a positioning structure that is slidably connected to the mounting base. This ensures that the displacement of the positioning and clamping structures during installation is along the first direction and will not result in offset. After the positioning and clamping structures are in place, the clamping structure contacts and engages with the part to be clamped, providing a force along the first direction to the part to be clamped, ensuring a tight fit between the part to be clamped and the fixed base. At this point, the installation is completed by locking the position of the positioning structure using the locking structure. Therefore, the clamping assembly of this application has the advantages of easy installation and positioning, effectively reducing installation difficulty and preventing damage to the part to be clamped, which is beneficial to improving the yield rate.

[0034] Combination Figures 1 to 3 , Figure 1 This is one of the application scenario diagrams of the clamping component 300 in one embodiment of this application. Figure 2 This is one of the application scenarios of the clamping component 300 in one embodiment of this application. Figure 3 This is a schematic diagram of the positioning structure and the connection structure of the clamping component in one embodiment of this application.

[0035] An embodiment of this application provides a clamping assembly 300 applied to a converter, which includes a housing 100 and a component to be clamped 200 (e.g., a high-power component). The housing 100 includes a fixing base 130 and a mounting base 140, which are arranged along a first direction X. The fixing base 130 is the portion of the housing 100 used to fix and mount the component to be clamped 200, and can exchange heat with the component to be clamped 200 to conduct the heat generated by the component to be clamped 200, ensuring the stable and safe operation of the component to be clamped 200 and preventing damage due to overheating. The mounting base 140 is the portion of the housing 100 used to mount the clamping assembly 300. The mounting base 140 is arranged adjacent to the fixing base 130, with the component to be clamped 200 located on the side of the fixing base 130 closer to the mounting base 140. When the clamping assembly 300 is mounted on the mounting base 140, the clamping assembly 300 can clamp the component to be clamped 200 onto the fixing portion.

[0036] Exemplarily, the housing 100 further includes a base plate 110 and a plurality of side plates 120. The base plate 110 extends along a plane formed by a first direction X and a second direction Y. The plurality of side plates 120 are respectively fixed perpendicularly to the base plate 110 and together with the base plate 110 form a mounting cavity. The fixing seat 130, the mounting seat 140, the member to be pressed 200, and the pressing assembly 300 are all located within the mounting cavity. The fixing seat 130 extends along a third direction Z and is fixed perpendicularly to the base plate 110. The mounting seat 140, the pressing assembly 300, and the member to be pressed 200 are located on the same side of the fixing seat 130 in the first direction X. The member to be pressed 200 is mounted on one side wall of the fixing seat 130 in the first direction X. The aforementioned first direction X, second direction Y, and third direction Z are all perpendicular to each other.

[0037] The clamping assembly 300 includes a positioning structure 310, a clamping structure 320, and a locking structure 330. The positioning structure 310 is in contact with the mounting base 140 and is slidably connected to the mounting base 140 along the first direction X. The clamping structure 320 is fixedly connected to the positioning structure 310, and one side of the clamping structure 320 in the first direction X is in contact with the part 200 to be clamped. The locking structure 330 is connected to both the positioning structure 310 and the mounting base 140 to lock the relative position of the positioning structure 310 and the mounting base 140.

[0038] When the positioning structure 310 slides along the first direction X, the positioning structure 310 and the clamping structure 320 can move closer to or further away from the mounting base 140 simultaneously. Since the part to be clamped 200 is located on the side of the fixed base 130 closer to the mounting base 140, when the positioning structure 310 slides toward the fixed base 130, pressure toward the fixed base 130 can be applied to the part to be clamped 200 through the clamping structure 320 fixedly connected to the positioning structure 310, thereby making the part to be clamped 200 tightly adhere to the fixed base 130, ensuring the installation stability of the part to be clamped 200 and the heat conduction effect between the part to be clamped 200 and the housing 100.

[0039] In this embodiment, the mounting base 140 guides and limits the positioning structure 310, ensuring that the displacement of the positioning structure 310 and the pressing structure 320 along the first direction X during installation will not cause any deviation. After the positioning structure 310 and the pressing structure 320 are moved into place, the pressing structure 320 contacts and engages with the part to be pressed 200, providing a force along the first direction X to the part to be pressed 200, ensuring a tight fit between the part to be pressed 200 and the fixing base 130. At this time, the installation can be completed by locking the position of the positioning structure 310 with the locking structure 330.

[0040] In some embodiments, the positioning structure 310 and the pressing structure 320 are plate-shaped or approximately plate-shaped structures, and the positioning structure 310 and the pressing structure 320 are arranged at an angle. One end of the positioning structure 310 is fixedly connected to one end of the pressing structure 320, so that the positioning structure 310 and the pressing structure 320 are combined to form an L-shape.

[0041] Optionally, the clamping structure 320 is an elastic plate to achieve elastic clamping of the part to be clamped 200.

[0042] Optionally, the positioning structure 310 and the clamping structure 320 are made of metal, such as stainless steel, which has good structural performance and thermal conductivity. In addition, when the interaction force between the clamping structure 320 and the part to be clamped 200 is large, the clamping structure 320 or the connection position between the clamping structure 320 and the positioning structure 310 can undergo elastic deformation to avoid excessive compression of the part to be clamped 200 and damage to the part to be clamped 200.

[0043] In some embodiments, the mounting base 140 is provided with two slide rails 141, and a groove 142 extending along the first direction X is formed between the two slide rails 141 (see...). Figure 5 The positioning structure 310 is located within the slide groove 142, and both sides of the positioning structure 310 slide in contact with the corresponding slide rails 141. Optionally, the slide rails 141 are elongated structures protruding from the upper side of the mounting base 140. When the positioning structure 310 is located between the two slide rails 141, the slide rails 141 on both sides can guide and limit the positioning structure 310, thus preventing the positioning structure 310 and the clamping structure 320 from tilting. Limiting the positioning structure 310 with two slide rails 141 has the advantages of simple structure and ease of production and installation.

[0044] The mounting base 140 and the housing 100 can be separately formed and fixedly connected by means such as bonding or welding, or they can be formed as one piece. No specific limitation is made here.

[0045] In some embodiments, the locking structure 330 includes at least one snap-fit ​​protrusion 333, and at least one slide rail 141 is provided with a slot 1411 on the side facing the positioning structure 310. The snap-fit ​​protrusion 333 engages with the slot 1411 to limit the movement of the positioning structure 310 and the slide rail 141 along the first direction X.

[0046] Optionally, both slide rails 141 are provided with slots 1411, and there are two or more locking protrusions 333, which are respectively placed on both sides of the positioning structure 310. The locking protrusions 333 on both sides of the positioning structure 310 respectively engage with the slots 1411 on the slide rail 141 on the same side.

[0047] The engagement of the snap-fit ​​protrusion 333 with the slot 1411 creates a movement limit for the positioning structure 310 and the slide rail 141 along the first direction X. This increases the stability of the clamping assembly 300 when clamping the workpiece 200, and simplifies the installation process, improving installation speed and accuracy. When installing the clamping assembly 300, the positioning structure 310 is first inserted into the slide groove 142, and then the positioning structure 310 and the clamping structure 320 are pushed along the first direction X, causing them to move towards the workpiece 200 until the snap-fit ​​protrusion 333 enters the slot 1411. At this point, the positioning structure 310 and the clamping structure 320 are in place, and their positions are fixed by the engagement of the snap-fit ​​protrusion 333 and the slot 1411, offering the advantage of easy installation.

[0048] In some embodiments, the positioning structure 310 includes a positioning part 311 and a sliding part 312.

[0049] The positioning part 311 is plate-shaped or nearly plate-shaped. The positioning part 311 is located in the slide groove 142 and contacts and cooperates with the bottom of the slide groove 142. The positioning part 311 is connected to the pressing structure 320 and the locking structure 330 to achieve positioning.

[0050] Two sliding portions 312 are provided, which are respectively placed on both sides of the positioning portion 311 and are both located in the slide groove 142. The sliding portion 312 has a long strip structure and extends along the first direction X. One end of the sliding portion 312 along the first direction X is fixedly connected to the positioning portion 311, and there is a gap between the other end and the positioning portion 311 to form a first groove 314 between the sliding portion 312 and the positioning portion 311. The engaging protrusion 333 is located on the side of the sliding portion 312 away from the first groove 314.

[0051] Combination Figure 5 , Figure 6 and Figure 7 When the positioning structure 310 is located within the slide groove 142, the two sliding parts 312 slidably contact and cooperate with the corresponding slide rails 141 to achieve sliding guidance. Since the snap-fit ​​protrusion 333 protrudes from the side wall of the sliding part 312, when the snap-fit ​​protrusion 333 slides between the two slide rails 141, the squeezing force between the slide rails 141 and the sliding part 312 will increase. In order to enable the snap-fit ​​protrusion 333 to smoothly slide into the slot 1411 and avoid damage to the positioning structure 310 and the slide rails 141, this embodiment provides a first groove 314 between the sliding part 312 and the positioning part 311. When the snap-fit ​​protrusion 333 slides between the two slide rails 141, the sliding part 312 and / or the connection position between the sliding part 312 and the positioning part 311 undergoes elastic deformation. When the snap-fit ​​protrusion 333 slides into the slot 1411 or slides out of the position between the two slide rails 141, the sliding part 312 returns to its original position.

[0052] In some embodiments, the end of the sliding portion 312 facing the pressing structure 320 is fixedly connected to the positioning portion 311, and the snap-fit ​​protrusion 333 is located on the side of the sliding portion 312 away from the pressing structure 320 that is opposite to the first groove 314.

[0053] This allows the snap-fit ​​protrusion 333 to be moved away from the connection position between the sliding part 312 and the positioning part 311. When the snap-fit ​​protrusion 333 is squeezed by the side wall of the slide rail 141, the sliding part 312 is more likely to undergo elastic deformation. In addition, during the process of the snap-fit ​​protrusion 333 sliding into the slot 1411, the sliding distance of the snap-fit ​​protrusion 333 on the inner side of the slide rail 141 is shorter, which helps to reduce the installation difficulty of the clamping assembly 300.

[0054] Optionally, the sliding part 312 and the positioning part 311 are integrally formed, which helps to reduce the production difficulty and production cost of the pressing assembly 300 and improve the connection strength between the sliding part 312 and the positioning part 311.

[0055] Combination Figure 3 and Figure 6 In some embodiments, the positioning structure 310 is provided with a first positioning hole 315, which is an elongated hole extending along a first direction X, and the first positioning hole 315 penetrates the positioning structure 310 along a third direction Z. The mounting base 140 is provided with a guide post 143, which is slidably inserted through the first positioning hole 315. When the positioning structure 310 slides along the first direction X, the guide post 143 can slide within the first positioning hole 315.

[0056] The locking structure 330 includes a first threaded member 331, which can be a bolt or screw, etc. The first threaded member 331 is threadedly connected to the guide post 143, and the head of the first threaded member 331 is located on the side of the positioning structure 310 opposite to the mounting base 140. The projected width of the head of the first threaded member 331 on the positioning structure 310 is greater than the width of the first positioning hole 315, thereby limiting the movement of the positioning structure 310 in the third direction Z.

[0057] In this embodiment, the guide post 143 can limit the movement of the positioning structure 310 when it slides, ensuring symmetry on both sides of the positioning structure 310. On the other hand, it can prevent the first threaded component 331 from directly contacting the positioning structure 310 and affecting its sliding. During installation, the positioning structure 310 is first placed in the slide groove 142, and the guide post 143 passes through the first positioning hole 315. Both the guide rail and the guide post 143 limit the movement of the positioning structure 310 along the second direction Y. Then, the first threaded component 331 is... 31 is installed on the guide post 143. The first threaded part 331 forms a limit on the positioning structure 310 along the third direction Z. At this time, the positioning structure 310 can slide along the first direction X until the pressing structure 320 presses the part to be pressed 200. When the locking structure 330 includes the snap-fit ​​protrusion 333 and the slide rail 141 is provided with the slot 1411, the positioning structure 310 slides along the first direction X until the snap-fit ​​protrusion 333 is snapped into the slot 1411, so as to achieve accurate positioning of the positioning structure 310 and the pressing structure 320.

[0058] Combination Figure 3 and Figure 7 In some embodiments, the positioning structure 310 is provided with a second positioning hole 316, which is a circular through hole. The locking structure 330 includes a second threaded component 332, which can be a screw or bolt, etc. The second threaded component 332 passes through the second positioning hole 316 and is threadedly connected to the mounting base 140 to lock the relative position of the positioning structure 310 and the mounting base 140.

[0059] When the second threaded component 332 passes through the second positioning hole 316 and is threadedly connected to the mounting base 140, it can cooperate with the mounting base 140 to simultaneously limit the positioning structure 310 in the first direction X, the second direction Y and the third direction Z, thereby completely locking the relative position of the positioning structure 310 and the mounting base 140.

[0060] During the specific installation process, when the positioning structure 310 is slid along the first direction X until the second positioning hole 316 is aligned with the threaded hole on the mounting base 140 for installing the second threaded component 332, the clamping structure 320 can just clamp the component 200 to be clamped. At this time, screwing in the second threaded component 332 can fix the positions of the positioning structure 310 and the clamping structure 320.

[0061] Understandably, when the locking structure 330 includes the snap-fit ​​protrusion 333 and the slide rail 141 is provided with a slot 1411, when the snap-fit ​​protrusion 333 is snapped into the slot 1411, the second positioning hole 316 is precisely aligned with the threaded hole on the mounting base 140 for installing the second threaded component 332, facilitating the installation of the second threaded component 332. After the second threaded component 332 is installed, it can limit the positioning structure 310 along the first direction X, preventing the snap-fit ​​protrusion 333 from being damaged by prolonged stress.

[0062] Optionally, the positioning structure 310 is provided with two or more second positioning holes 316, and the locking structure 330 includes at least two second threaded members 332. Each second positioning hole 316 has a corresponding second threaded member 332, and each second threaded member 332 is threadedly connected to the mounting base 140. For example, the positioning structure 310 is provided with one first positioning hole 315 and two second positioning holes 316. The two second positioning holes 316 are located on both sides of the extension direction of the first positioning hole 315. The locking structure 330 includes one first threaded member 331 and two second threaded members 332. The first threaded member 331 is threadedly connected to the guide post 143 passing through the first threaded member 331, and the two second threaded members 332 are respectively passed through the two second positioning holes 316 and threadedly connected to the mounting base 140.

[0063] Combination Figure 4 In some embodiments, the pressing structure 320 is provided with at least one pressing protrusion 321, and the pressing structure 320 contacts and engages with the part 200 to be pressed through the pressing protrusion 321.

[0064] For example, the crimping protrusion 321 is a protrusion structure formed by bending a portion of the pressing structure 320 toward the side close to the fixing part. The surface of the crimping protrusion 321 toward the fixing part is a spherical surface. When the pressing structure 320 presses the member to be pressed 200, the crimping protrusion 321 forms a support, and other positions of the pressing structure 320 do not contact the member to be pressed 200.

[0065] Optionally, the clamping structure 320 is provided with two or more pressing protrusions 321, which facilitates the individual clamping of multiple parts 200 to be clamped, or the clamping of each part 200 to be clamped by multiple pressing protrusions 321.

[0066] By setting the pressing protrusion 321, the position of the interaction force between the pressing structure 320 and the part to be pressed 200 can be accurately determined, resulting in a better pressing effect on the part to be pressed 200. In addition, the contact area between the pressing structure 320 and the part to be pressed 200 can be reduced, so that the reaction force of the part to be pressed 200 on the pressing structure 320 is concentrated at the pressing protrusion 321. This ensures that the reaction force has a sufficient lever arm length, which causes the pressing structure 320 to undergo elastic deformation. During long-term use, the pressing assembly 300 can always maintain the pressing state of the part to be pressed 200.

[0067] Combination Figure 1 and Figure 3 In some embodiments, the pressing structure 320 includes a connecting portion 322 and a plurality of elastic portions 323. The connecting portion 322 is fixedly connected to the positioning structure 310 and the plurality of elastic portions 323 respectively. A second groove 324 is formed between adjacent elastic portions 323, and the pressing protrusion 321 is located on the elastic portion 323.

[0068] For example, a plurality of elastic portions 323 are arranged at intervals along the second direction Y, and the ends of the plurality of elastic portions 323 facing the mounting base 140 are fixedly connected to the connecting portion 322, and the ends of the connecting portion 322 facing the mounting base 140 are fixedly connected to the positioning structure 310.
