[0024] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described 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. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0025] like Figure 6 As shown, considering that the material of the boss 11 (such as the boss 11 of the motor housing) may be a softer material such as plastic, or may be a material harder than plastic such as cast aluminum or cast steel, although the serrated clamping structure can be embedded in the boss 11 made of plastic, it is difficult to embed in hard materials such as cast aluminum or cast steel, which may cause the clamping structure to fall off.
[0026] like Figures 1 to 5 As shown, the clamping structure of the hand-piece mounting pad of the present application adopts a clamping method of clamping on both sides, that is, after the end of the boss 11 extends between the two elastic sheets 32, the two elastic sheets 32 are deformed, so that the two elastic sheets 32 are pressed on both sides of the boss 11, and at the same time, the pressure plate 31 is pressed on the hand piece 1 (such as the motor housing), and finally the mounting pad 2 (such as sound insulation cotton and heat insulation cotton, etc.) is pressed and set on the hand piece 1. On the one hand, because it does not need to be embedded in the inside of the boss 11, it can be applied to both the boss 11 made of plastic materials and the boss 11 such as cast aluminum and cast steel, thereby expanding the scope of application. On the other hand, because it does not need to be embedded in the inside of the boss 11, in the clamping process of the two elastic sheets 32, because the clamping is achieved by surface contact or line contact, the contact area between the elastic sheet 32 and the boss 11 is large, and the pressure of the elastic sheet 32 on the surface of the boss 11 is reduced, thereby protecting the external structure of the boss 11 and avoiding damage to the surface of the boss 11 caused by the clamping structure during the clamping process.
[0027] like Figures 1 to 3 As shown, a clamping structure for a hand piece mounting pad of an embodiment of the present application, the clamping structure is used to press and set the mounting pad 2 on the hand piece 1, the mounting pad 2 is at least partially located between the pressure plate 31 and the hand piece 1, the clamping structure 3 includes a pressure plate 31, an opening 311 is provided on the pressure plate 31, two elastic sheets 32 are provided on opposite sides of the opening 311, the hand piece 1 includes a boss 11 extending toward the pressure plate 31, so that one end of the boss 11 passes through the opening 311, the maximum distance between the two elastic sheets 32 is a first length, the minimum distance of the boss 11 along a cross section perpendicular to the extension direction is a second length, the second length is greater than the first length, one end of the boss 11 is used to pass between the two elastic sheets 32, the two deformed elastic sheets 32 are clamped and fixed on the boss 11, so that the pressure plate 31 is pressed and set on the hand piece 1, and the mounting pad 2 is pressed and set on the hand piece 1 through the pressure plate 31.
[0028] In combination with the above embodiments, the mounting pad 2 clamped and fixed by the clamping structure is a non-moving part with a small load, such as heat insulation cotton, sound insulation cotton, shock absorbing pad, sealing ring, etc., and the counterpart 1 can be a motor housing, a gear box housing, a bearing housing, etc. The clamping structure 3 is plate-shaped as a whole, and the main part of the clamping structure 3 is a pressing plate 31. The shape of the pressing plate 31 is adapted to the shape of the part of the pressing plate 31 facing the counterpart 1, increasing the contact area between the pressing plate 31 and the counterpart 1, so that the pressing plate 31 can be fully pressed on the counterpart 1.
[0029] Furthermore, the mounting pad 2 can be completely located between the pressing plate 31 and the opponent 1, and the mounting pad 2 is pressed and set on the opponent 1 by the pressing plate 31. This situation is suitable for the case where the mounting pad 2 is small in area and the area of the mounting pad 2 is less than or equal to the area of the plate surface of the pressing plate 31. The mounting pad 2 can also be partially located between the pressing plate 31 and the opponent 1, and the pressing plate 31 presses a part of the mounting pad 2 on the opponent 1, and the other part of the mounting pad 2 can be glued to the opponent 1. This situation is suitable for the case where the mounting pad 2 is large in area and the area of the mounting pad 2 is larger than the area of the plate surface of the pressing plate 31.
[0030] The opening 311 is formed on the pressing plate 31 by stamping. The shape of the opening 311 on the plate surface of the pressing plate 31 can be a strip shape, a circle shape, an ellipse shape, a triangle shape, etc. A boss 11 is correspondingly provided on the hand piece 1. Correspondingly, the shape of the boss 11 can be adapted to the shape of the opening 311. When the opening 311 is in a strip shape, the shape of the boss 11 can be a plate surface. When the opening 311 is circular, the shape of the boss 11 is cylindrical. When the opening 311 is elliptical, the shape of the boss 11 is an elliptical column. When the opening 311 is triangular, the shape of the boss 11 is a triangular prism. The shape of the boss 11 is adapted to the shape of the opening 311, so that the structure of the clamping structure 3 after assembly with the hand piece 1 is compact.
[0031] In addition, two elastic sheets 32 are respectively provided on both sides of the opening 311. Each elastic sheet 32 can produce elastic deformation when disturbed by external force. Since the distance between the two elastic sheets 32 is smaller than the thickness of the boss 11, after the boss 11 passes through the opening 311 and the two elastic sheets 32 in sequence, the two elastic sheets 32 are deformed, so that the ends of the two elastic sheets 32 are pressed against the boss 11, and the pressure plate 31 is fixed by the two elastic sheets 32, so that the pressure plate 31 is pressed against the opponent part 1, and finally the pressing installation of the mounting pad 2 is realized.
[0032] like Figure 2 and Figure 3As shown, the clamping structure for the hand piece mounting pad of the embodiment of the present application, the boss 11 includes two parallel outer side surfaces, the vertical distance between the two outer side surfaces is the second length, the opening 311 includes two parallel inner side surfaces, the vertical distance between the two inner side surfaces is the third length, and the third length is greater than the second length, so that one end of the boss 11 can pass through the opening 311.
[0033] In combination with the above embodiments, the shape of the boss 11 is plate-like, the spacing between the two outer side surfaces of the boss 11 is the thickness of the boss 11, the shape of the opening 311 on the plate surface of the pressure plate 31 is a strip hole, the distance between the two inner side surfaces of the opening 311 is the width of the opening 311, and the width of the opening 311 needs to be greater than the thickness of the boss 11. In addition, the length of the opening 311 is greater than the length of the boss 11, so that the end of the boss 11 can pass through the opening 311.
[0034] In the embodiment of the present application, the clamping structure for the hand piece mounting pad is formed by stamping the pressure plate 31 to form the opening 311 and the two elastic sheets 32. One end of each of the elastic sheets 32 is integrally connected to the inner side surface corresponding to the opening 311. Each of the elastic sheets 32 is arc-shaped along a cross-section perpendicular to its extension direction, so that the other end of each of the elastic sheets 32 is pressed and connected to the boss 11.
[0035] In combination with the above embodiment, the opening 311 and the two elastic sheets 32 are formed by stamping, and the two elastic sheets 32 are integrally formed with the pressure plate 31. Each elastic sheet 32 is curved as a whole after being bent. After the top of the boss 11 passes through the two elastic sheets 32, the two elastic sheets 32 are deformed, and the top of each elastic sheet 32 is pressed against the side of the boss 11 after deformation, thereby achieving the clamping of the elastic sheet 32. Since the contact between the elastic sheet 32 and the outer side surface of the boss 11 is surface-to-surface release or line-to-surface contact, the damage to the surface of the boss 11 when the clamping structure 3 is clamped on the boss 11 is reduced.
[0036] like Figures 4 to 6 As shown, in the hand piece mounting pad clamping structure of the embodiment of the present application, the length of each elastic sheet 32 is smaller than the length of the opening 311 , so that a gap is left between the two ends of each elastic sheet 32 and the pressure plate 31 .
[0037] In combination with the above embodiment, the length of each elastic sheet 32 is smaller than the length of the opening 311, so that a gap is left between the two ends of each elastic sheet 32 and the two ends of the opening, so as to prevent the inner side wall of the opening 311 from contacting the bottom of the elastic sheet 32, thereby interfering with the normal deformation of the elastic sheet 32. Two folded edges 312 are also stamped at both ends of the pressing plate 31, and the bending direction of each folded edge 312 is consistent with the bending direction of the elastic sheet 32.
[0038] In the hand piece mounting pad clamping structure of the embodiment of the present application, the opening 311 is rectangular in shape, the boss 11 is plate-like in shape, the thickness of the pressure plate 31 is 0.3 to 0.5 mm, the width of the opening 311 is 2 to 5 mm, the thickness of the boss 11 is 3 to 6 mm, and the height of the boss 11 is 1 to 4 mm.
[0039] like Figure 4 As shown, the clamping structure of the hand piece mounting pad of the embodiment of the present application, the hand piece 1 is a motor housing, and plate ribs are provided on the motor housing to form the boss 11, and the mounting pad 2 is sound insulation cotton, and a mounting seam is provided on the sound insulation cotton. The sound insulation cotton is mounted on the motor housing through the mounting seam, and the sound insulation cotton is also pressed against the motor housing by the pressure plate 31.
[0040] In combination with the above embodiment, when the hand piece 1 is a motor housing, the motor housing is installed on the chassis of the car, the motor of the car is installed in the motor housing, the mounting pad 2 is sound insulation cotton, and plate ribs are provided on the motor housing to form a boss 11. The sound insulation cotton is coated on the outer surface of the motor housing, and a mounting seam is provided on the sound insulation surface. After the boss 11 passes through the mounting seam, two elastic sheets 32 are clamped on the two outer sides of the boss 11, thereby pressing the sound insulation cotton on the motor housing, thereby effectively preventing the sound insulation cotton from falling off, and preventing the sound insulation cotton from being impacted and falling off when the car crosses a puddle (wading).
[0041] The clamping structure of the hand-piece installation pad of the present application adopts a clamping method of clamping on both sides, that is, after the end of the boss 11 extends into the two elastic sheets 32, the two elastic sheets 32 are deformed, so that the two elastic sheets 32 are pressed on both sides of the boss 11, and at the same time, the pressure plate 31 is pressed on the hand piece 1 (such as the motor housing), and finally the installation pad 2 (such as sound insulation cotton and heat insulation cotton, etc.) is pressed and set on the hand piece 1. On the one hand, because it does not need to be embedded in the inside of the boss 11, it can be applied to both the boss 11 made of plastic materials and the boss 11 such as cast aluminum and cast steel, thereby expanding the scope of application. On the other hand, because it does not need to be embedded in the inside of the boss 11, in the clamping process of the two elastic sheets 32, due to the clamping method of surface contact or line contact, the contact area between the elastic sheet 32 and the boss 11 is large, and the pressure of the elastic sheet 32 on the surface of the boss 11 is reduced, thereby playing a role in protecting the external structure of the boss 11 and avoiding damage to the surface of the boss 11 caused by the clamping structure 3 during the clamping process.
[0042] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
