DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] This application proposes a mounting structure. Figures 1 to 6 These are some embodiments of the present application.

[0044] See also Figures 1 to 3 In some embodiments of the present application, the mounting structure 100 is configured to be connected to the accumulator, that is, the mounting structure 100 can form an accumulator assembly by connecting to the accumulator, and then a sleeve is installed on the outer surface of the mounting structure 100, and the accumulator assembly is screwed to the installation position of the vehicle through the sleeve to complete the assembly of the accumulator in the vehicle.

[0045] The mounting structure in the embodiments of the present application can be a hexagonal head in the background technology, or a component of other structural forms. For example, in one embodiment of the present application, it can be a square nut; in another embodiment of the present application, it can be an octagonal nut; no limitation is made here.

[0046] Among them, the mounting structure 100 includes a main body 1, which is provided with a first cavity 11. The first cavity 11 is used to avoid the air sealing cover 10 of the accumulator. In the first direction X, the outer diameter dimension of the main body 1 is L1, and the vertical distance between the inner wall of the first cavity 11 and the outer wall 7 of the main body 1 is L2. L1 and L2 satisfy: 0.125≤L2 / L1≤0.16; wherein, the main body 1 is the main part of the mounting structure 100, and occupies a larger part of the volume and weight of the mounting structure 100.

[0047] In the technical solution of the present application, the outer diameter dimension L1 of the main body 1 and the vertical distance L2 between the inner wall of the first cavity 11 and the outer wall 7 of the main body 1 are set to meet the interval range of 0.125≤L2 / L1≤0.16, so as to ensure that under the set installation torque, when the accumulator is screwed into the working pipeline of the vehicle, the installation structure 100 will not be deformed or fall off the accumulator during the rotation screw connection due to its own insufficient strength.

[0048] In some embodiments of the present application, the value of L1 is 22 mm; therefore, the value of L2 satisfies 2.75 mm ≤ L2 ≤ 3.52 mm, which can ensure that the mounting structure will not be deformed or fall off the accumulator during the rotation and screwing process due to its own insufficient strength.

[0049] Among them, the value of L2 can be 2.75mm, 2.77mm, 2.79mm, 2.81mm, 2.83mm, 2.85mm, 2.87mm, 2.89mm, 2.91mm, 2.93mm, 2.95mm, 2.97mm, 2.99mm, 3.01mm, 3.03mm, 3.05mm, 3.07mm, 3.09mm, 3.11mm, 3.13mm, 3.14mm, 3.16mm, 3.18mm, 3.20mm, 3.22mm, 3.24mm, 3.26mm, 3.28mm, 3.30mm, 3.32mm, 3.34mm, 3.36mm, 3.38mm, 3.40mm, 3.42mm, 3.44mm, 3.46mm, 3.48mm, 3.50mm, and 3.52mm. The value of L2 is not limited to the listed values, and other values ​​not listed within the numerical range are also applicable.

[0050] In some embodiments of the present application, L2 also satisfies: L2 ≥ 3 mm; that is, in this embodiment, L2 is set to be greater than or equal to 3 mm to further ensure that the mounting structure will not be deformed or fall off the accumulator during the rotation and screwing process due to its own insufficient strength.

[0051] In some embodiments of the present application, 3mm≤L2≤3.52mm; that is, in this embodiment, the value of L2 is designed to satisfy the interval range of 3mm≤L2≤3.52mm, so as to further ensure that the mounting structure will not be deformed or fall off the accumulator during the rotational screw connection due to its own insufficient strength.

[0052] In addition, in the first direction X, the vertical distances between various locations of the inner wall of the first cavity 11 and the outer wall 7 of the main body 1 may be equal or unequal; this is not limited here.

[0053] In some embodiments of the present application, the dimension of the first cavity 11 in the first direction X is L3, and L3 satisfies: 14.96mm≤L3≤16.5mm; in this embodiment set, the dimension of L3 is designed to satisfy this interval range, so that the first cavity 11 can accommodate the air sealing cover 10 while not occupying too much dimension of the main body 1 in the first direction X, thereby ensuring that the value of L2 can meet the installation strength of the main body, and avoiding the installation structure 100 from being deformed or falling off the accumulator during the rotation threading process due to insufficient strength under the set installation torque.

[0054] If L3 is less than 14.96 mm, there may be a problem that the structural part of the main body 1 interferes with the gas sealing cover 10, making it difficult to assemble the mounting structure 100 with the accumulator.

[0055] If L3 is greater than 16.5 mm, the L3 value of the main body 1 may be too small, resulting in insufficient structural strength of the main body 1, and further causing the mounting structure to deform or fall off the accumulator under the action of the mounting torque.

[0056] Among them, the value of L3 can be 14.96mm, 14.98mm, 15mm, 15.02mm, 15.04mm, 15.06mm, 15.08mm, 15.10mm, 15.12mm, 15.14mm, 15.16mm, 15.18mm, 15.20mm, 15.22mm, 15.24mm, 15.26mm, 15.28mm, 15.30mm, 15.32mm m, 15.34mm, 15.36mm, 15.38mm, 15.40mm, 15.42mm, 15.44mm, 15.46mm, 15.48mm, 15.50mm, 15.5 2mm, 15.54mm, 15.56mm, 15.58mm, 15.60mm, 15.62mm, 15.64mm, 15.66mm, 15.68mm, 15.70mm, 15. 72mm, 15.74mm, 15.76mm, 15.78mm, 15.80mm, 15.82mm, 15.84mm, 15.86mm, 15.88mm, 15.90mm, 1 5.92mm, 15.94mm, 15.96mm, 15.98mm, 16mm, 16.02mm, 16.04mm, 16.06mm, 16.08mm, 16.10mm, 16. 12mm, 16.14mm, 16.16mm, 16.18mm, 16.20mm, 16.22mm, 16.24mm, 16.26mm, 16.28mm, 16.30mm, 16.32mm, 16.34mm, 16.36mm, 16.38mm, 16.40mm, 16.42mm, 16.44mm, 16.46mm, 16.48mm, 16.50mm. The value of L3 is not limited to the listed values, and other values ​​not listed within the numerical range are also applicable.

[0057] In some embodiments of the present application, the mounting structure 100 and the accumulator are connected by pressure welding.

[0058] In some embodiments of the present application, the mounting structure 100 has an end wall 4 and a first connecting wall 5, the end wall 4 is arranged away from the main body 1 and is configured to contact the accumulator, and the first connecting wall 5 connects the end wall 4 and the outer wall 7; the first connecting wall 5 includes a first slope 51, one end of the first slope 51 is connected to the end wall 4, and the first slope 51 is configured to limit the liquid from adhering to the first connecting wall 5 and the accumulator; wherein, after the mounting structure 100 and the accumulator are welded, there will be residual electroplating solution at the angle between the mounting structure 100 and the accumulator, so the first slope is provided to limit the excessive electroplating solution from adhering to the first connecting wall 5 and the accumulator.

[0059] It is understandable that when the gap between the first connecting wall 5 and the accumulator is small, part of the electroplating solution will be in the gap between the first connecting wall 5 and the accumulator due to capillary phenomenon, and this part of the electroplating solution is not easy to flow out of the gap between the first connecting wall 5 and the accumulator due to surface tension.

[0060] In some embodiments of the present application, the angle between the plane where the first inclined surface 51 is located and the first direction X is α, and α satisfies: 63°≤α≤67°; that is, in this embodiment, by setting the α value to satisfy this interval range, the electroplating solution is prevented from adhering to the gap between the first connecting wall 5 and the accumulator due to capillary phenomenon, thereby preventing the electroplating solution from being hidden in the gap between the first connecting wall 5 and the accumulator.

[0061] It should be added that when a liquid comes into contact with a solid, capillary phenomenon will occur if the attraction between the liquid molecules and the solid surface is greater than the cohesive force between the liquid molecules.

[0062] If α is less than 63°, part of the electroplating solution may still adhere to the gap between the first connecting wall 5 and the accumulator due to capillary phenomenon.

[0063] If α is greater than 67 degrees, the first inclined surface 51 may occupy the area of ​​the outer wall 7, making the area of ​​the outer wall smaller, thereby reducing the L2 value of the main body 1 and affecting the installation strength of the installation structure.

[0064] The value of α may be 63°, 63.2°, 63.4°, 63.6°, 63.8°, 64°, 64.2°, 64.4°, 64.6°, 64.8°, 65°, 65.2°, 65.4°, 65.6°, 65.8°, 66°, 66.2°, 66.4°, 66.6°, 66.8°, 67°. The value of α is not limited to the listed values, and other values ​​not listed within the numerical range are also applicable.

[0065] In some embodiments of the present application, the value of α is 65°, which can prevent the electroplating solution from staying in the gap between the first connecting wall 5 and the accumulator due to capillary phenomenon, and at the same time ensure the welding strength between the mounting structure 100 and the accumulator, so that the mounting structure 100 is not easy to fall off from the accumulator under the action of the mounting torque.

[0066] See also Figures 4 to 6In some embodiments of the present application, the mounting structure 100 further includes a convex portion 2, which is located on one side of the main body 1 in the second direction Y; wherein the end wall 4 is located on the side of the convex portion 2 away from the main body 1. wherein, when the mounting structure 100 is connected to the accumulator, the end wall 4 contacts the surface of the accumulator, and the mounting structure 100 and the accumulator are welded by pressure welding, at which time the convex portion 2 will be melted.

[0067] In some embodiments of the present application, the first inclined surface 51 also extends onto the protrusion 2 ; this configuration facilitates the processing and forming of the first inclined surface 51 on the mounting structure.

[0068] In some embodiments of the present application, at least a portion of the first inclined surface 51 also extends onto the main body.

[0069] In some embodiments of the present application, the dimension of the protrusion 2 in the second direction Y is L4, and L4 satisfies: 0.45mm≤L4≤0.55mm; in this embodiment, by designing the value of L4 to satisfy this interval, it can be ensured that the mounting structure 100 is firmly fixed to the accumulator after welding.

[0070] If the value of L4 is less than 0.45 mm, the connection strength between the mounting structure 100 and the accumulator after welding may be reduced, resulting in the mounting structure 100 and the accumulator being separated when the accumulator is installed.

[0071] If the value of L4 is greater than 0.55 mm, the protrusion 2 may not be completely melted, resulting in a phenomenon in which a portion of the mounting structure 100 and the accumulator are not firmly attached after the protrusion 2 is melted.

[0072] In some embodiments of the present application, if the value of L4 is greater than 0.55 mm, there may be a phenomenon that a portion of the connecting portion 3 is not firmly fitted to the accumulator.

[0073] The value of L4 can be 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, 0.50 mm, 0.51 mm, 0.52 mm, 0.53 mm, 0.54 mm, 0.55 mm. The value of L4 is not limited to the listed values, and other values ​​not listed in the numerical range are also applicable.

[0074] In some embodiments of the present application, the mounting structure 100 also includes a connecting portion 3, which is located between the protrusion 2 and the main body 1, and connects the protrusion 2 and the main body 1; wherein the connecting portion 3 is provided with a second cavity 31, the second cavity 31 is connected to the first cavity 11 and is configured to avoid the air sealing cover 10 of the accumulator; in the second direction Y, the size of one end of the second cavity 31 close to the first cavity 11 is smaller than the size of one end of the second cavity 31 away from the first cavity 11; such a configuration is due to the fact that the connecting surface between the accumulator and the mounting structure 100 is an arc surface, and by reducing the contact area between the connecting portion 3 and the accumulator after the protrusion 2 is welded and melted, a gap between the connecting portion 3 and the accumulator is avoided on the basis of ensuring the connection strength between the mounting structure 100 and the accumulator.

[0075] In this embodiment, in the second cavity 31 , the size of one end of the second cavity 31 close to the first cavity 11 and the size of one end of the second cavity 31 far from the first cavity 11 are sufficient, and the size of other parts of the second cavity 31 is not limited.

[0076] In some embodiments of the present application, the protrusion 2 is provided with a third cavity 21, and the third cavity 21 is connected to the second cavity 31; the inner wall of the second cavity 31 has a second inclined surface 6, one end of the second inclined surface 6 is connected to the inner wall of the third cavity 21, and the projection of the second inclined surface 6 in the second direction Y falls outside the first cavity 11; by providing the second inclined surface 6, the contact area between the connecting portion 3 and the accumulator can be reduced after the protrusion 2 is welded and melted, thereby avoiding the existence of a gap between the connecting portion 3 and the accumulator on the basis of ensuring the connection strength between the mounting structure 100 and the accumulator.

[0077] The design of the second inclined surface 6 also facilitates the operation of tooling to process the mounting structure 100 .

[0078] In some embodiments of the present application, the first cavity 11 , the second cavity 31 and the third cavity 21 are all for avoiding the air sealing cover 10 .

[0079] In some embodiments of the present application, in the second direction Y, the first cavity 11 is arranged to penetrate the main body 1; this arrangement makes it easy for operators or operating tools to process the electroplating solution remaining in the first cavity 11, the second cavity 31 and the third cavity 21, so as to avoid the electroplating solution remaining in the first cavity 11, the second cavity 31 and the third cavity 21.

The accumulator also includes a diaphragm 9 located in the chamber, which divides the chamber into an air chamber space 12 and an oil chamber space 13.

[0082] The air sealing cover 10 blocks the opening of the air chamber space 12 .
