[0007] In some embodiments, the first heat-conducting block is fixedly disposed on the first mounting base. When the upper housing is installed on the upper housing, the first heat-conducting block abuts against the thermistor and the control base plate at the corresponding position of the thermistor.

Detailed Implementation

[0015] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0016] like Figure 1-4 As shown, this utility model provides a vehicle suspension pump for convenient temperature monitoring, mainly including an upper housing 100 with a mounting position for mounting a control base plate 101. The control base plate 101 is detachably mounted on the mounting position of the upper housing 100. A thermistor 1012 for temperature monitoring is provided on the control base plate 101. The thermistor 1012 is located on the lower side of the control base plate 101, i.e., the side facing the lower housing 200. The thermistor 1012 is connected to the control base plate 101 for signal transmission, feeding back the measured signal to the control center of the control base plate 101. The lower housing 200 has a first cavity, within which a drive motor 201 is installed. The outer casing of the motor 201 is provided with a first mounting base 2011, which is connected to the outer casing of the drive motor 201. The position of the first mounting base 2011 corresponds to the position of the thermistor 1012. The first mounting base 2011 protrudes a certain height relative to the casing of the drive motor 201. A first heat-conducting block 2012 is provided between the first mounting base 2011 and the control base plate 101. The first heat-conducting block 2012 has a preset length. One end of the first heat-conducting block 2012 abuts against the control base plate 101, and the other end of the first heat-conducting block 2012 abuts against the first mounting base 2011. At the same time, the first heat-conducting block 2012 covers and contacts the thermistor 1012.

[0017] In this application, a first mounting base 2011 is provided on the outside of the housing of the drive motor 201, and a first heat-conducting block 2012 is provided between the first mounting base 2011 and the control base plate 101. The first heat-conducting block 2012 abuts against the thermistor 1012. The heat generated by the drive motor 201 is transferred to the first mounting base 2011 through its housing, and then transferred to the thermistor 1012 located on the lower side of the control base plate 101 through the first mounting base 2011 and the first heat-conducting block 2012. This reduces the heat transfer path. Compared with the traditional method of pre-embedded thermistor and wire winding, the assembly structure is simple, the transfer path is short and stable, and more accurate measurement data is provided.

[0018] In one embodiment, the first heat-conducting block 2012 has an elastic abutment section at one end near the control base plate 101. This elastic abutment section can deform to a certain extent during assembly, and it abuts and covers both the control base plate 101 and the thermistor 1012 mounted on the control base plate 101, thereby achieving a better heat transfer path. In this embodiment, to ensure a certain deformation, the first heat-conducting block is made of silicone rubber with aluminum oxide, boron nitride, etc. This ensures good heat transfer while allowing for a certain amount of deformation to meet the height requirement of the thermistor 1012 protruding relative to the control base plate 101. Simultaneously, the material strength of the first heat-conducting block 2012 is guaranteed even at high temperatures, ensuring the stability of the heat transfer structure.

[0019] In one embodiment, as another variation of the above-described embodiment, a first clearance groove can be provided at one end of the first heat-conducting block 2012. The depth of the first clearance groove is consistent with the height of the thermistor 1012 protruding relative to the control base plate 101. At the same time, the shape of the thermistor 1012 is consistent with the shape of the first clearance groove. That is, the vertical projection contours of the first clearance groove and the thermistor 1012 on the control base plate 101 are consistent, thereby adapting to each other. While ensuring that the first heat-conducting block 2012 can cover the thermistor 1012, it can also achieve contact with the surfaces of the first heat-conducting block 2012 and the thermistor 1012, ensuring the heat transfer effect.

[0020] In one embodiment, for ease of assembly, the first heat-conducting block 2012 is first fixedly mounted on the first mounting base 2011. When the upper housing 100 is mounted on the lower housing 200, the first heat-conducting block 2012 abuts against the thermistor 1012 and the corresponding position of the control base plate 101. In this embodiment, the first heat-conducting block 2012 can be fixed by adhesive, screws, or other snap-fit ​​structures. The first heat-conducting block 2012 can also be integrally formed with the housing of the drive motor 201. In this case, a silicone layer of a certain thickness needs to be provided at the contact point between the first heat-conducting block 2012 and the control base plate 101 to avoid hard contact damage to the thermistor 1012 caused by the first heat-conducting block 2012 integrally formed with the housing of the drive motor.

[0021] Furthermore, such as Figure 5 As shown, a first mounting groove 20111 is provided on the first mounting base 2011. The first mounting groove 20111 has a preset width, which is consistent with the width of the first heat-conducting block 2012, thus matching it. The length of the first mounting groove 20111 is greater than the length of the first heat-conducting block 2012, thereby fixing the first heat-conducting block 2012 at different positions on the first mounting base 2011, and then abutting against the thermistor 1012, which is set at slightly different positions on the control base plate 101. In this embodiment, the vertical projection outline of the first heat-conducting block 2012 on the control base plate 101 is slightly larger than the vertical projection of the thermistor 1012 on the control base plate 101. While ensuring the heat transfer effect, it reduces the space occupied by the first heat-conducting block 2012 on the control base plate 101, thereby making room for other components on the control base plate 101. In addition, it can also reduce the space occupied by the first heat-conducting block 101 in the upper housing 100 and the lower housing 200, and reduce the raw material consumption of the first heat-conducting block 2012.

[0022] In one embodiment, since the first heat-conducting block 2012 is first fixed on the first mounting base 2011 during assembly, and the control base plate 101 is assembled on the upper housing 100 and the drive motor 201 is assembled inside the lower housing 200, positioning is required when assembling the upper housing 100 and the lower housing 200 to ensure that the positions of the first heat-conducting block 2012 and the thermistor 1012 correspond and abut. Specifically, a first limiting mechanism is provided between the upper housing 100 and the lower housing 200. The first limiting structure includes a first positioning pin 102 disposed on the upper housing 100 and a first positioning hole 202 disposed on the lower housing 200; the positions of the first positioning hole 202 and the first positioning pin 102 correspond, and during assembly, the first positioning pin 102 is inserted into the first positioning hole 202. In this embodiment, there are two first positioning holes 202 and two first positioning pins 102, and the first positioning holes 202 are asymmetrically arranged relative to the lower housing 200, thereby ensuring that the upper housing 100 and the lower housing 200 have only one assembly direction during the assembly process.

[0023] Optionally, the first positioning hole 202 can also be provided on the upper housing 100, and the first positioning pin 102 can also be provided on the lower housing 200, which can also achieve the above positioning purpose.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
