[0024] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.
[0025] The coil in the transformer is provided with winding space through the skeleton and the coil is positioned. Secondly, the skeleton can also play the role of insulating various components in the transformer.
[0026] However, in actual use, the frame between the magnetic core and the coil takes up a large space, making the transformer larger.
[0027] In order to solve the technical problem that the above-mentioned frame occupies a large space and causes the transformer to be larger in size, the first embodiment of the present application provides a transformer. Figure 1 and Figure 2 The transformer includes a base 100, a magnetic core component 200, a coil component 300 and a support member 400, wherein the base 100 has a first direction X and a second direction Y intersecting each other; the magnetic core component 200 includes a first portion 210 and a second portion 220, wherein the first portion 210 extends along the second direction Y, the second portion 220 is connected to the first portion 210, and the second portion 220 is connected to the base 100 along the first direction X; the coil component 300 is sleeved on the first portion 210, and is spaced apart from the first portion 210 to form a gap 150; a portion of the support member 400 is connected to the base 100, a portion of the support member 400 is located in the gap 150 and is sleeved on the first portion 210, the support member 400 is spaced apart from the first portion 210, and the portion of the support member 400 sleeved on the first portion 210 is connected to the coil component 300 to support the coil component 300, and the support member 400 can have mutual inductance with the coil component 300.
[0028] In some embodiments, the magnetic core assembly 200 is an EE-type magnetic core assembly 200 , and the first portion 210 and the second portion 220 are respectively composed of two E-type magnetic cores along the second direction Y.
[0029] In some embodiments, the coil assembly 300 is formed by a plurality of coils nested within each other, that is, among any two coils in the coil assembly 300 , one is nested within the other.
[0030] Specifically, the support member 400 is made of metal.
[0031] Specifically, the coil in the coil assembly 300 can transfer energy with the support member 400 through electromagnetic mutual induction to achieve voltage conversion.
[0032] Among them, the support member 400 is connected to the base 100, so that the relative position of the support member 400 and the base 100 is fixed. In some embodiments, the support member 400 is snap-fitted to the base 100; the magnetic core assembly 200 is also connected to the base 100, so that the relative position of the magnetic core assembly 200 and the base 100 is fixed. Therefore, the relative position of the support member 400 and the magnetic core assembly 200 is also fixed through the base 100, so that the support member 400 and the first part 210 of the magnetic core assembly 200 can maintain a distance.
[0033] In some embodiments, the transformer further includes an insulating member disposed between the support member 400 and the first portion 210 to insulate the support member 400 from the first portion 210. Specifically, the insulating member is wrapped around the first portion 210. In some embodiments, the insulating member is an insulating tape.
[0034] In the above embodiment, the support member 400 is passed through the coil assembly 300, and the coil assembly 300 is wound around the support member 400. The support member 400 supports the coil assembly 300, reduces the probability of deformation of the coil assembly 300, and improves the reliability of the transformer. In addition, the support member 400 can have mutual inductance with the coil assembly 300 and can be used as a coil. In other words, the support member 400 also acts as a skeleton as a coil, so that the transformer does not need to be provided with an additional skeleton, thereby reducing the volume of the transformer.
[0035] In addition, the support member 400 passing through the coil assembly 300 along the second direction Y can conduct the heat generated by the coil assembly 300 away from the coil assembly 300 along the second direction Y, thereby improving the heat dissipation performance of the transformer.
[0036] In addition, since the support member 400 needs to support the coil assembly 300 along the second direction Y, the size of the support member 400 along the second direction Y is larger than the size of the single-turn coil in the coil assembly 300. When the support member 400 is used as a single-turn coil, it can withstand a larger current, thereby making the transformer's transformation range larger and the performance better.
[0037] In some embodiments, see Figure 2 and Figure 7 The base 100 has a first through hole 110, which passes through the base 100 along the first direction X; the support member 400 includes a main body 410 and a first flange 420, the main body 410 has a second through hole 411, the second through hole 411 extends along the second direction Y, and the first part 210 is passed through the second through hole 411; the first flange 420 is connected to a side of the main body 410 facing the base 100 along the first direction X, the first flange 420 is located on a side of the coil assembly 300 along the second direction Y, the first flange 420 passes through the first through hole 110, and is connected to the base 100.
[0038] In the above embodiment, the first flange 420 passing through the first through hole 110 serves to connect the support member 400 and the base 100, so that the relative positions of the support member 400 and the base 100 are fixed to maintain the interval setting between the first part 210 and the support member 400.
[0039] In addition, when the support member 400 is used as a coil, the first flange 420 can serve as a pin of the support member 400 so that the support member 400 can be connected to the circuit and the transformer can be soldered to the circuit board.
[0040] In addition, the first flange 420 is located on one side of the coil assembly 300 along the second direction Y. The first flange 420 can also limit the coil assembly 300 along the second direction Y to prevent the coil assembly 300 from shifting along the second direction Y.
[0041] It is understandable that the first flange 420 increases the surface area of the support member 400. The first flange 420 located outside the coil assembly 300 can enhance the heat dissipation effect of the support member 400 as a heat sink, thereby improving the reliability of the transformer.
[0042] In some embodiments, see Figure 3 and Figure 4 The transformer includes a plurality of support members 400 , and the plurality of support members 400 are arranged at intervals along the second direction Y.
[0043] Specifically, the plurality of support members 400 are sleeved on the first portion 210 along the second direction Y and are spaced apart.
[0044] In the above embodiment, a plurality of support members 400 are provided so that the number of coils served by the support members 400 can be adjusted. Figure 4 It can be found that Figure 4 The transformer includes two support members 400 spaced apart along the second direction Y. Compared with the transformer having only one support member 400, Figure 4 The transformer provided in the invention does not increase in size after the number of coils is increased, and the structure of the transformer is more compact.
[0045] In some embodiments, please refer again to Figure 3 and 4 , the coil assembly 300 is located between at least two first flanges 420 along the second direction Y.
[0046] Specifically, the coil assembly 300 is located between the first flanges 420 of two support members 400 at both ends along the second direction Y among the plurality of support members 400 , so as to limit the position of the coil assembly 300 in the second direction Y.
[0047] In the above embodiment, the coil assembly 300 is disposed between the first flanges 420 of the two support members 400 along the second direction Y, so as to better limit the position of the coil assembly 300 along the second direction Y.
[0048] In some embodiments, see Figure 5 and Figure 6 The base 100 also has a third direction Z, and the first direction X, the second direction Y and the third direction Z intersect with each other; the support member 400 also includes a second flange 430, and the second flange 430 is connected to one side of the body 410 along the third direction Z, and the second flange 430 is located on one side of the coil assembly 300 along the second direction Y.
[0049] In some embodiments, please refer again to Figure 3 and Figure 4 , the coil assembly 300 is located between at least two second flanges 430 along the second direction Y.
[0050] It is understood that the coil assembly 300 is wound around the first portion 210 along the circumference of the first portion 210. In the above embodiment, the first flange 420 can limit the portion of the coil assembly 300 located between the support member 400 and the base 100 along the first direction X along the second direction Y. By providing the second flange 430 in a direction different from the first flange 420, the portion of the coil assembly 300 located on one side of the body 410 along the third direction Z can be limited along the second direction Y. The support member 400 in this embodiment better limits the position of the coil assembly 300 along the second direction Y.
[0051] In some embodiments, the support member 400 includes a plurality of second flanges 430 , at least two second flanges 430 are respectively connected to two sides of the body 410 along the third direction Z, and at least two second flanges 430 are spaced apart along the first direction X.
[0052] In the above embodiment, the support member 400 having at least two second flanges 430 connected to the main body 410 on both sides along the third direction Z can simultaneously limit the coil assembly 300 on both sides of the main body 410 along the third direction Z, that is, the support member 400 in this embodiment better limits the coil assembly 300 along the second direction Y.
[0053] In some embodiments, please refer again to Figure 6 The main body 410, the first flange 420 and the second flange 430 are integrally formed.
[0054] In some embodiments, the main body 410 , the first flange 420 , and the second flange 430 are formed by bending the same thin plate. Specifically, the main body 410 , the first flange 420 , and the second flange 430 are formed by bending different parts of the same thin plate.
[0055] In some embodiments, please refer again to Figure 6 The main body 410 has a first surface 412 and a second surface 413 that are opposite to each other along the first direction X, and the second surface 413 faces the base 100. The main body 410 has a third through hole 414, and the third through hole 414 passes through the main body 410 along the second direction Y. The third through hole 414 passes through the second surface 413 and is connected to the second through hole 411.
[0056] It is understood that in some embodiments, the body 410 is formed by bending a thin plate, and the third through hole 414 is a seam formed by the two ends of the body 410 facing each other after the bending. The ends of the seam along the third direction Z may tend to move away from each other, causing the body 410 to deform and the coil assembly 300 to deform accordingly. In the above embodiment, by orienting the second surface 413 of the body 410 with the seam toward the base 100, the base 100 can better restrain the parts of the body 410 and the coil assembly 300 that may deform due to the ends of the seam along the third direction Z tending to move away from each other, thereby preventing deformation of the body 410 and the coil assembly 300 of the support member 400, thereby improving the reliability of the transformer.
[0057] In some embodiments, please refer again to Figure 4 、 Figure 5 and Figure 7 The base 100 includes a substrate 120 and a boss 130. The substrate 120 has a first through hole 110. The first through hole 110 passes through the substrate 120 along the first direction X. Part of the support member 400 is arranged on the substrate 120. The coil assembly 300 is connected to the side of the substrate 120 facing the support member 400 along the first direction X; the boss 130 is located between the substrate 120 and the magnetic core assembly 200 along the first direction X, and connects the base 100 and the magnetic core assembly 200 respectively. The boss 130 makes the magnetic core assembly 200 and the support member 400 spaced apart along the first direction X. The boss 130 has a receiving groove 131 on the side of the boss 130 facing the support member 400 along the first direction X. Part of the coil assembly 300 and part of the support member 400 are arranged in the receiving groove 131.
[0058] In some embodiments, the first through hole 110 is in communication with the receiving groove 131 .
[0059] In the above embodiment, the boss 130 can limit the coil assembly 300 and the support member 400 along the second direction Y and the third direction Z, and can also limit the magnetic core assembly 200 along the first direction X. Furthermore, the portions of the support member 400 and the limiting assembly that face the base 100 along the first direction X tend to deform, increasing in size along the third direction Z. By embedding these portions within the accommodating cavity, the boss 130 can prevent this tendency, thereby preventing deformation of the support member 400 and the coil assembly 300 and improving the reliability of the transformer.
[0060] In some embodiments, please refer again to Figure 4 、 Figure 5 and Figure 7The base 100 also includes a side wall 140, which is connected to the side of the substrate 120 along the first direction X toward the support member 400. The side wall 140 is arranged around the boss 130 and is spaced apart from the boss 130 to form a gap 150. Part of the coil assembly 300 is arranged in the gap 150 and passes through the boss 130 and the side wall 140. The side wall 140 is connected to the magnetic core assembly 200.
[0061] In some embodiments, the boss 130 has a first through groove, which allows the accommodating cavity and the gap 150 to be connected, and a portion of the coil assembly 300 can pass through the boss 130, so that the accommodating groove 131 and the gap 150 are connected, and the wires in the coil assembly 300 can pass through the boss 130; in some embodiments, the side wall 140 has a second through groove, which allows the gap 150 to be connected to the outside of the side wall 140, and the second through groove allows a portion of the coil assembly 300 to pass through the side wall 140, so that the gap 150 and the outside of the side wall 140 are connected, and the wires in the coil assembly 300 can pass through the side wall 140 to be electrically connected to the external circuit.
[0062] Specifically, the side wall 140 is disposed around the magnetic core assembly 200 and is connected to the magnetic core assembly 200 .
[0063] In the above embodiment, the side wall 140 is used to limit the magnetic core assembly 200 along the second direction Y and the third direction Z to prevent the magnetic core assembly 200 from moving in the base 100, causing the first step of the magnetic core assembly 200 to contact the support member 400, thereby improving the reliability of the transformer.
[0064] Correspondingly, the present application also provides a vehicle, comprising a transformer as described in any one of the above embodiments.
[0065] The above is a detailed introduction to a transformer and a vehicle provided in the embodiments of the present application.
