[0023] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).
[0024] In a first aspect, please refer to Figures 1-3 , in an embodiment, a vehicle inductor is provided, including: a coil 1, a bracket 2, and a current guiding row 3. Lead-out ends 11 are provided at both axial ends of the coil 1. The lead-out ends 11 are electrically connected to the wound part of the coil 1, and the provision of the lead-out ends facilitates the electrical connection between the current guiding row 3 and the coil 1. The coil 1 is sleeved on the bracket 2, and the bracket 2 has a first end 21 and a second end 22 arranged oppositely along the axis of the coil 1.
[0025] The current guiding row 3 includes a straight section 31 and legs 32. At least one end of the straight section 31 is connected with a leg 32, and a bending part 33 is formed at the connection part of the leg 32 and the straight section 31. For example, two legs 32 can be provided, and the two legs 32 are respectively connected to both ends of the straight section 31. One leg 32 is fixed to the first end 21, and the other leg 32 is fixed to the second end 22.
[0026] Specifically, the current guiding row 3 can be of an integral structure. After the two ends of the current guiding row 3 are bent, two legs 32 are respectively formed, and a straight section 31 is formed in the middle of the current guiding row 3. The current guiding row 3 is installed on the bracket 2 through the two legs 32, and the straight section 31 of the current guiding row 3 is located above the coil 1. The current guiding row 3 is electrically connected to the lead-out end 11 of the coil 1, and the current guiding row 3 is used to introduce or export current to the coil 1.
[0027] The straight section 31 is provided with a first strengthening structure 311, and the first strengthening structure 311 is used to prevent the straight section 31 from bending. The bent portion 33 is provided with a second strengthening structure 321, and the second strengthening structure 321 is used to prevent the bending angle of the bent portion 33 from changing. Since the straight section 31 of the current guiding row 3 is relatively long, setting the first strengthening structure 311 can strengthen the straight section 31 and improve the anti-bending ability of the straight section 31; the bent portion 33 is provided with the second strengthening structure 321, and the second strengthening structure 321 can strengthen the bent portion 33, improve the anti-deformation ability of the bent portion 33, and make the connection between the leg 32 and the straight section 31 more firm. The first and second strengthening structures 321 can enhance the structural strength of the current guiding row 3, and it is not easy for the current guiding row 3 to bend and deform after being vibrated.
[0028] In one embodiment, please refer to Figure 2 and Figure 3 , the first strengthening structure 311 is a first protrusion formed on one side of the straight section 31 in the thickness direction. Specifically, the first protrusion can be formed by stamping the current guiding row 3 and is located on the side of the straight section 31 close to the coil 1. The setting of the first protrusion can increase the strength of the straight section 31, and the straight section 31 is not easy to bend and deform.
[0029] In some other embodiments, the first protrusion can also be arranged on the side of the straight section 31 far from the coil 1. Or, the first strengthening structure 311 can also be a reinforcing rib or a reinforcing plate fixed on the straight section 31, and the connection manner between the reinforcing rib or the reinforcing plate and the straight section 31 can be welding, bonding or clamping. In some other embodiments, the shape of the reinforcing rib can also be a curve, such as a sine wave shape.
[0030] In one embodiment, please refer to Figures 1-3 , the first strengthening structure 311 extends along the length direction of the straight section 31. Since the straight section 31 of the current guiding row 3 has a relatively large size in the length direction and the current guiding row 3 is only fixed by the legs 32 at both ends, the anti-deformation ability of the straight section 31 is poor. Setting the first strengthening structure 311 along the length direction can increase the strength of the straight section 31, and the straight section 31 is not easy to bend.
[0031] In one embodiment, please refer to Figure 1 and Figure 2, the length of the first strengthening structure 311 is at least two-thirds of the length of the straight section 31. The purpose of the above setting is to fully enhance the anti-deformation ability of each position of the straight section 31 in the length direction, so that the straight section 31 is not easily bent after being vibrated. For example, the length of the first strengthening structure 311 can be the same as or slightly less than the length of the straight section 31.
[0032] In some other embodiments, multiple first strengthening structures 311 can be provided on the straight section 31, and each strengthening structure is arranged along the length direction of the diversion row 3. The sum of the lengths of the multiple first strengthening structures 311 can be greater than the length of the straight section 31.
[0033] In one embodiment, please refer to Figures 1-3 , in the width direction of the straight section 31, the first strengthening structure 311 is located at the middle position of the straight section 31. In the above setting, when the straight section 31 is stressed, in the width direction, the forces on both sides of the first strengthening structure 311 are symmetrical, and it is not easy to bend or deform towards one side.
[0034] In one embodiment, please refer to Figures 1-3 , the second strengthening structure 321 is a second protrusion formed on the bending part 33, and the second protrusion is located on the concave side of the bending part 33. Specifically, the second protrusion can be formed by stamping the bending part 33 of the diversion row 3. The setting of the second protrusion can strengthen the bending part 33 and improve the anti-deformation ability of the bending part 33, making the connection between the leg 32 and the straight section 31 more firm. In this embodiment, the second protrusion and the first protrusion are both located on the same side of the diversion row 3, and the stamping directions during the forming of the diversion row 3 are the same, which is convenient for processing.
[0035] In one embodiment, please refer to Figures 1-3 , in the width direction of the bending part 33, the second strengthening structure 321 is located at the middle position of the bending part 33. In the above setting, when the bending part 33 is stressed, in the width direction, the forces on both sides of the second strengthening structure 321 are symmetrical, and it is not easy to bend or deform towards one side.
[0036] In one embodiment, please refer to Figures 1-3 , the first strengthening structure 311 is a first rib, and the second strengthening structure 321 is a second rib. Specifically, a first deformation part is provided on the straight section 31, and the convex side of the first deformation part forms the first rib, and the side of the first deformation part opposite to the first rib is concave. A second deformation part is provided on the bending part 33, and the convex side of the second deformation part forms the second rib, and the side of the second deformation part opposite to the second rib is concave.
[0037] The current-carrying bar 3 is generally made of a relatively soft conductive material, such as copper or aluminum. The first rib and the second rib can be formed on the current-carrying bar 3 by stamping, which is relatively convenient for processing. Moreover, the first rib and the second rib can effectively increase the strength of the straight section 31 and the bending part 33, so that the current-carrying bar 3 is not easily deformed when subjected to vibration.
[0038] In one embodiment, please refer to Figures 1-3 , the current-carrying bar 3 includes two legs 32, and the two legs 32 are respectively connected to both ends of the straight section 31. At least one leg 32 is provided with an inclined section 322, and the inclined section 322 is located between the bending part 33 and the bracket 2. Specifically, the leg 32 fixed to the first end 21 of the bracket 2 is provided with an inclined section 322, and the inclined section 322 serves to connect the straight section 31 and the bracket 2. At the same time, compared with the straight section 31 directly extending to the first end 21 of the bracket 2, setting the inclined section 322 can reduce the length of the straight section 31, and the straight section 31 has better strength and is not easily deformed.
[0039] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention pertains, based on the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
