In an embodiment of the present application, the sensor assembly may specifically include: a sensor body 10, and a bush 20; a limiting bulge 11 is arranged on the sensor body 10; the bush 20 comprises a bush body 21 and a plurality of cantilever spring pieces 22 arranged along the circumferential direction of the bush body 21, the bush body 21 is fixedly connected with the sensor body 10, the bush body 21 is sleeved on the sensor body 10, the cantilever spring pieces 22 extend towards the direction far away from the bush body 21, the free ends of the cantilever spring pieces 22 and the limiting protrusions 11 are arranged at intervals to be used for clamping the sensor support 30, and the sensor support 30 is suitable for installing the sensor body 10.
In the embodiment of the present application, the sensor assembly is generally fixed to the vehicle, the electronic device, and other devices requiring sensor installation through the sensor bracket 30. In the embodiment of the present application, the sensor body 10 may also be understood as a sensor, and the sensor includes, but is not limited to, a wheel speed sensor, a temperature sensor, etc. the embodiment of the present application only takes the wheel speed sensor as an example, and the structure, principle and installation process of the sensor assembly are exemplified, and other references may be implemented.
As shown in fig. 1 and 2, in practical applications, in order to improve the structural stability of the sensor on the sensor holder 30, a mounting through hole 301 is usually formed on the sensor holder 30, and the sensor assembly is fixed in the mounting through hole 301, so as to avoid the sensor from shaking or the like on the sensor holder 30.
In this application embodiment, establish on sensor body 10 through bush body 21 cover, and be located between the inner wall of sensor body 10 and installation through-hole 301 to can carry out circumference to sensor body 10 through bush body 21 and fix, effectively promote the stability of being connected between bush body 21 and the sensor body 10.
In this embodiment, one end of the cantilever spring 22 fixedly connected to the bushing body 21 may be referred to as a fixed end of the cantilever spring 22, and the other end of the cantilever spring 22 extending towards the direction away from the bushing body 21 may be referred to as a free end of the cantilever spring 22, so that the free end of the cantilever spring 22 can move towards the direction close to the bushing body 21 or away from the bushing body 21.
In practical applications, the cantilever spring 22 may be integrally formed with the bushing body 21. Specifically, an opening 201 is arranged on the bushing body 21 at a position opposite to the cantilever spring plate 22, and the size of the opening 201 is larger than or equal to that of the cantilever spring plate 22; the cantilever spring plate 22 comprises a closed state and an open state; when the cantilever spring 22 is in the closed state, the cantilever spring 22 is located in the opening 201, and when the cantilever spring 22 is in the open state, the cantilever spring 22 is separated from the opening 201. In the embodiment of the present application, the cantilever spring 22 with the above structure has a simple structure and is low in processing difficulty.
In the embodiment of the present application, when the cantilever spring 22 is in the closed state, the cantilever spring 22 is recessed in the opening 201 or the cantilever spring 22 is flush with the outer surface of the bushing body 21. In practical application, a groove can be formed in the position, opposite to the opening 201, of the sensor body 10, so that when the cantilever elastic piece 22 is in a closed state, the cantilever elastic piece 22 can be sunken into the groove, and therefore when the sensor assembly is arranged in the installation through hole 301 in the sensor support 30 in a penetrating mode, the sensor assembly is smoother.
In practical applications, the distance between the limiting protrusion 11 and the cantilever spring 22 can be controlled to match the size of the sensor holder 30, for example, the distance L between the limiting protrusion 11 and the free end of the cantilever spring 22 is equal to the width T of the sensor holder 30. When the sensor assembly is mounted on the sensor support 30, the sensor assembly can be inserted into the mounting through hole 301 from the fixed end of the cantilever spring 22, because the free end of the cantilever spring 22 is movable, in the mounting process of the sensor assembly, the cantilever spring 22 is inserted into the mounting through hole 301, the cantilever spring 22 gradually becomes a closed state (as shown in fig. 1) from an open state due to the radial tightening force of the mounting through hole 301, until the cantilever spring 22 completely passes through the mounting through hole 301, the cantilever spring 22 is no longer bound by the mounting through hole 301, therefore, the cantilever spring 22 can recover to the open state (as shown in fig. 2), and at this time, the sensor support 30 is fixed between the limiting protrusion 11 and the cantilever spring 22 by being clamped. In the embodiment of the present application, the sensor assembly is fixed to the sensor bracket 30, and only the installation through hole 301 needs to be formed in the sensor bracket 30, so that the processing of the sensor bracket 30 is simplified, and in the process of fixing the sensor assembly to the sensor bracket 30, only the cantilever spring plate 22 needs to be inserted into the installation through hole 301, which is simple and convenient.
Optionally, the plurality of cantilever spring pieces 22 are uniformly arranged along the circumferential direction of the bushing body 21.
In the embodiment of the application, through evenly setting up a plurality of cantilever shell fragments 22 along the circumference of bush 20, can make the effect of cantilever shell fragment 22 joint sensor support 30 better, the structure is more stable, moreover, also can effectively reduce cantilever shell fragment 22's the processing degree of difficulty like this.
It can be understood that the limiting protrusion 11 disposed on the sensor body 10 is opposite to the cantilever spring plate 22, and therefore the limiting protrusion 11 is also disposed along the axial direction of the sensor body 10, specifically, the limiting protrusion 11 may be an annular limiting protrusion 11, or there may be a plurality of limiting protrusions 11, the plurality of limiting protrusions 11 are uniformly disposed along the circumferential direction of the sensor body 10 and are opposite to the cantilever spring plate 22, and those skilled in the art may set the limiting protrusion 11 according to actual conditions, which is not specifically limited in this embodiment of the present application.
In practical applications, the bushing body 21 may be a nested ring; the sensor body 10 is inserted into the nesting ring. That is, the bush body 21 is disposed around the circumference of the sensor body 10, which makes it possible to make the structure between the sensor body 10 and the bush body 21 more stable.
Specifically, in the embodiment of the present application, the nested ring may also be a semi-enclosed nested ring or an enclosed nested ring. Referring to fig. 5, a schematic structural diagram of a bushing according to an embodiment of the present application is shown. As shown in fig. 5, the bushing body 21 is a semi-enclosed nested ring, or the bushing body 21 is in a non-closed ring shape, and the bushing body 21 has a gap 202. In practical application, the inner diameter of the semi-enclosed type nested ring can change along with the change of the size of the gap 202 on the bushing body 21, so that the semi-enclosed type nested ring can be compatible with the sensor bodies 10 with various sizes, and the assembly process of the sensor bodies 10 penetrating into the nested ring is simpler and more convenient.
In the embodiment of the application, the semi-closed nested ring can be formed by directly curling the plate, and the semi-closed nested ring is simple and convenient to process and low in cost.
In practical applications, before the sensor assembly is not assembled to the sensor holder 30, the inner diameter of the nesting ring may be slightly larger than the outer diameter of the sensor body 10, that is, the sensor body 10 is rotatable within the nesting ring or in a loose fit state between the sensor body 10 and the nesting ring, in the case that the sensor assembly is installed in the installation through hole 301 on the sensor holder 30, the installation through hole 301 performs a circumferential limiting and clamping function on the nesting ring, at this time, by compressing the size of the gap 202 on the nesting ring, the nesting ring performs a radial clamping function on the sensor body 10, at this time, the sensor body 10 and the nesting ring are relatively fixed, or the sensor body 10 and the nesting ring are in a tight fit state.
In this embodiment, the sensor body 10 is inserted into the nesting ring, and the connection mode between the sensor body 10 and the nesting ring may further include: the sensor body 10 is connected with the nested ring in an interference fit mode, a clamping connection mode, a bonding connection mode, a riveting connection mode or a plurality of modes, and therefore the reliability and the stability of connection between the sensor body 10 and the nested ring are improved. For example, the nesting ring may be a closed nesting ring, and the nesting ring is in interference fit with the sensor body 10, so that the sensor body 10 is prevented from falling off from the nesting ring by the fixed connection between the nesting ring and the sensor body 10. In the case of the interference fit connection, in order to further improve the connection reliability between the sensor body 10 and the grommet, the grommet may be bonded to the sensor body 10 or may be fixed to the sensor body 10 by caulking. One skilled in the art can select one or more of the above connection modes according to practical situations, and the embodiments of the present application are not limited thereto.
Referring to fig. 6, a schematic structural diagram of a sensor body according to an embodiment of the present application is shown. As shown in the figure, the sensor body 10 is further provided with a limiting groove 12, and the limiting groove 12 is arranged opposite to the limiting protrusion 11; the first end of the nested ring is abutted to the limiting protrusion 11, and the second end of the nested ring is embedded in the limiting groove 12. In the embodiment of the application, the limiting function of the limiting bulge 11 can be fully utilized, one end of the nested ring is abutted to the limiting bulge 11, and the other end of the nested ring is embedded in the limiting groove 12, so that the sensor body 10 and the nested ring are fixed.
In this application embodiment, in order to compromise the assembly convenience between the sensor body 10 and the nested ring, the connection structure of the sensor body 10 and the nested ring may specifically have the following connection mode: from the joint of the cantilever spring plate 22 and the bushing body 21 to the second end of the nested ring, the nested ring is provided with a contraction section 210; the sensor body 10 is provided with a reducing section 120 at a position opposite to the reducing section 210, and the outer dimension of the reducing section 120 is equal to the inner dimension of the reducing section 210. In the embodiment of the present application, the inner diameter of the reducing section 210 can be understood as a section of inward-contracting conical surface design, and from the joint of the cantilever spring 22 and the bushing body 21 to the second end of the nested ring, the inner diameters of the nested ring decrease sequentially, and correspondingly, the inner diameter of the reducing section 120 on the sensor body 10 also decreases sequentially with the inner diameter of the nested ring.
In the embodiment of the application, through the cooperation between the reducing section 210 of nested ring and the reducing section 120 of sensor body 10 to carry on spacingly to the other end of nested ring, simple structure, moreover, still compromise the assembly convenience between nested ring and the sensor body 10.
Of course, it can be understood that, when the sensor assembly is not assembled to the sensor holder 30, the inner diameter of the reducing pipe section 210 may be slightly larger than the outer diameter of the reducing section 120, and when the sensor assembly is assembled to the mounting through hole 301 of the sensor holder 30, the inner side surface of the reducing pipe section 210 is in contact with the outer surface of the reducing section 120, that is, the inner diameter of the reducing pipe section 210 is equal to the outer diameter of the reducing section 120.
