Description

Technical Field

[0001] The utility model relates to the field of pressure sensors, in particular to a sensor for an automobile and an automobile. Background Art

[0002] At present, the fixing method for a pressure sensor usually adopts a foaming component, that is, a connection and fixation is carried out between a pipe slot of a vehicle body fixing part and a fixing slot of the pressure sensor through the foaming component. This fixing method has relatively high requirements for structural design and technology. Therefore, the defective rate of finished products is relatively high, and the production cost is high. In addition, when using the foaming component to fix the pressure sensor, it is necessary to reserve a mounting hole position for the sensor body in the vehicle, which is likely to cause the overall fixing structure to be too large in volume.

[0003] The pressure sensor is generally fixed in the area near the upper and lower parts of the front bumper beam of the vehicle. The space in this area is limited. Therefore, the layout position of the sensor is restricted. In addition, when using an elastic buffer material as the foaming component to fix the pressure sensor, the fixing stability of the pressure sensor is restricted, and the foaming component is a disposable fixing part. If the foaming component is damaged, it cannot be reused, and the use and maintenance cost is high. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problem that the foaming component is a disposable fixing part and the connection surface between the foaming component and the fixing part cannot be reused after being damaged. The utility model provides a sensor for an automobile, which can fix the sensor in the vehicle by fixedly connecting the connecting piece with the sensor (including snap connection and crimping), and can disassemble and reuse the connecting piece and the sensor multiple times, reduce costs, reduce the installation volume, have a simple installation process and high efficiency, and can also match different vehicle body structures, with strong versatility.

[0005] To solve the above technical problems, an embodiment of the utility model discloses a sensor for an automobile, including:

[0006] A sensor body, along a first direction, the sensor body has an upper surface;

[0007] A fixing part, arranged on the upper surface, the fixing part includes:

[0008] A receiving cavity, along a second direction, one end of the receiving cavity has a first opening, along the first direction, the first opening has a first height, and the second direction is perpendicular to the first direction;

[0009] An elastic connecting piece, arranged in the receiving cavity, along the first direction, the elastic connecting piece is opposite to the upper surface, and a first distance exists between the lower surface of the elastic connecting piece and the upper surface in the first direction, and the first height is greater than the first distance; wherein,

[0010] The first opening is for an external connecting member to be inserted into the accommodating cavity, and after the connecting member passes between the lower surface and the upper surface of the elastic connecting member, the connecting member is fixedly connected to the elastic connecting member.

[0011] With the above technical solution, when it is necessary to install and fix an automotive sensor in a vehicle, an operator inserts the connecting member into the accommodating cavity of the fixing part of the automotive sensor. Subsequently, after the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body, the connecting member is fixedly connected to the elastic connecting member of the fixing part. Then, the operator can install and fix the other end of the connecting member in the vehicle.

[0012] Since the first opening of the accommodating cavity of the fixing part has a first height, and there is a first distance between the lower surface of the elastic connecting member of the fixing part and the upper surface of the sensor body, and the first height is greater than the first distance, when the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body, the connecting member will squeeze the elastic connecting member, causing the elastic connecting member to deform upward. After the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body, the elastic connecting member returns downward to its original state, and the connecting member is fixedly connected to the elastic connecting member.

[0013] When it is necessary to remove the automotive sensor from the vehicle, the operator first removes the other end of the connecting member from the vehicle, and then deforms the elastic connecting member upward to increase the first distance, so that the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body and exits from the accommodating cavity of the fixing part to complete the disassembly.

[0014] When it is necessary to install and fix the automotive sensor in the vehicle next time, just repeat the above steps. Therefore, the connecting member is fixedly connected to the sensor to fix the sensor in the vehicle, and the connecting member and the sensor can be disassembled and reused multiple times, reducing costs, reducing the installation volume, having a simple installation process and high efficiency, and can also match different body structures with strong versatility.

[0015] According to another specific embodiment of the present invention, the accommodating cavity has a first cavity wall, a second cavity wall and a third cavity wall. Along the second direction, the first cavity wall is opposite to and spaced from the elastic connecting member, and along the third direction, the second cavity wall and the third cavity wall are opposite to and spaced from each other;

[0016] The automotive sensor includes a connecting member, the connecting member has an insertion end, and along the first direction, the insertion end has a second height, and the second height is greater than the first distance;

[0017] Along the second direction, one end of the insertion end abuts against one end of the elastic connecting member, and the other end of the insertion end abuts against the first cavity wall of the accommodating cavity. Along the third direction, the two ends of the insertion end respectively abut against the second cavity wall and the third cavity wall of the accommodating cavity, and the third direction is perpendicular to the first direction.

[0018] With the above technical solution, the insertion end of the connecting member has a second height, and there is a first distance between the lower surface of the elastic connecting member of the fixing portion and the upper surface of the sensor body, and the second height is greater than the first distance.

[0019] Therefore, after the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body, along the second direction, one end of the insertion end of the connecting member abuts against one end of the elastic connecting member, and the other end of the insertion end abuts against the first cavity wall of the accommodating cavity. That is to say, in the second direction, the elastic connecting member and the first cavity wall of the accommodating cavity jointly clamp the insertion end. Along the third direction, the two ends of the insertion end respectively abut against the second cavity wall and the third cavity wall of the accommodating cavity. That is to say, in the third direction, the second cavity wall and the third cavity wall of the accommodating cavity jointly clamp the insertion end. That is, in the second direction, the first cavity wall of the accommodating cavity and the elastic connecting member play a limiting role on the insertion end of the connecting member, and in the third direction, the second cavity wall and the third cavity wall of the accommodating cavity play a limiting role on the insertion end of the connecting member, so that the connecting member and the elastic connecting member can be fixedly connected and will not shake due to the bumps of the vehicle body during the driving of the vehicle.

[0020] According to another specific embodiment of the present invention, the connecting member has a first through hole. Along the second direction, the first through hole is located on the right side of the insertion end. After the connecting member abuts against the elastic connecting member, the first through hole is used to accommodate the elastic connecting member. Along the second direction, the first through hole has a first length, and the elastic connecting member has a second length, and the first length is greater than the second length.

[0021] With the above technical solution, after the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body, the elastic connecting member returns to its original state, and the elastic connecting member is embedded in the first through hole of the connecting member.

[0022] When it is necessary to disconnect the vehicle sensor from the connecting member, the operator deforms the elastic connecting member upward. Since the first length of the first through hole of the connecting member is greater than the second length of the elastic connecting member, therefore, there is enough space in the second direction to deform the elastic connecting member so that the connecting member passes between the lower surface of the elastic connecting member and the upper surface of the sensor body and exits from the accommodating cavity of the fixing portion to complete the disassembly.

[0023] According to another specific embodiment of the utility model, the fixing portion has a convex portion, and along the third direction, the convex portion is spaced apart from the second cavity wall and the third cavity wall of the accommodating cavity respectively; along the second direction, one end of the convex portion is connected to the elastic connecting member, and the other end of the convex portion is spaced apart from the first cavity wall of the accommodating cavity; along the first direction, the convex portion is spaced apart from the upper surface of the sensor body; after the connecting member abuts against the elastic connecting member, along the first direction, the lower surface of the convex portion abuts against the upper surface of the insertion end of the connecting member, and the third direction is perpendicular to the first direction.

[0024] By adopting the above technical solution, when it is necessary to fix the automobile sensor to the connecting piece, the connecting piece passes through between the lower surface of the elastic connecting piece and the upper surface of the sensor body, the connecting piece abuts against the elastic connecting piece of the fixing part, the convex part of the fixing part is located above the connecting piece, the convex part of the fixing part presses the connecting piece, and applies a downward pressure to the connecting piece in a first direction, so that the connecting piece and the convex part of the fixing part can be fixedly connected, and will not shake due to the bumps of the automobile body during driving.

[0025] When it is necessary to disconnect the automobile sensor from the connecting piece, the operator applies an upward force in a first direction to the convex portion of the fixing part by bending the convex portion of the fixing part, so that the convex portion of the fixing part is deformed upward. Since one end of the convex portion of the fixing part is connected to the elastic connecting piece, the convex portion of the fixing part deforms upward together with the elastic connecting piece, so that the connecting piece passes between the lower surface of the elastic connecting piece and the upper surface of the sensor body, and withdraws from the accommodating cavity of the fixing part, completing the disassembly.

[0026] According to another specific embodiment of the present invention, a lower surface of the convex portion and the upper surface of the sensor body have a second distance in the first direction, and the second distance is greater than the first distance.

[0027] By adopting the above technical solution, when it is necessary to fix the automotive sensor to the connector, the lower surface of the convex portion of the fixing part and the upper surface of the sensor body have a second distance in the first direction, the lower surface of the elastic connector of the fixing part and the upper surface of the sensor body have a first distance, and the second distance is greater than the first distance, that is, in the first direction, the convex portion of the fixing part and the elastic connector of the fixing part have a height difference. Therefore, after the connector passes through the lower surface of the elastic connector and the upper surface of the sensor body, one end of the insertion end of the connector can abut against one end of the elastic connector.

[0028] According to another specific embodiment of the present invention, along the first direction, one end of the accommodating cavity has a second opening, the second opening exposes the convex portion of the fixing portion, and the second opening is directly opposite to the upper surface of the sensor body.

[0029] With the above technical solution, through the second opening of the accommodation cavity, it can be observed whether the connecting member is fixedly connected to the elastic connecting member of the fixing portion in place.

[0030] According to another specific embodiment of the present invention, the vehicle sensor includes a pressure tube. Along the second direction, one end of the sensor body is provided with a connecting portion, and the connecting portion and the first opening of the accommodation cavity are located on the same side, and the connecting portion is connected to the pressure tube by interference fit.

[0031] With the above technical solution, the pressure tube and the first opening of the accommodation cavity are located on the same side, avoiding damage to the connecting portion of the sensor body due to the bending requirement of the pressure tube.

[0032] According to another specific embodiment of the present invention, the fixing portion and the sensor body are integrally formed.

[0033] With the above technical solution, the fixing portion and the sensor body are integrally formed. Therefore, when manufacturing the mold for the vehicle sensor, only one mold needs to be produced, reducing the production cost.

[0034] An embodiment of the present invention also discloses a vehicle, including:

[0035] An installation portion;

[0036] The vehicle sensor according to any one of the foregoing, wherein the elastic connecting member of the vehicle sensor is fixedly connected to the connecting member, and the other end of the connecting member is connected to the installation portion.

[0037] According to another specific embodiment of the present invention, the other end of the connecting member has a second through hole, and the second through hole is threadedly connected to the installation portion.

[0038] With the above technical solution, one end of the insertion end of the connecting member abuts against one end of the elastic connecting member, the convex portion of the fixing portion is located above the connecting member, and the convex portion of the fixing portion presses the connecting member, so that the fixing portion is fixedly connected to the connecting portion. The second through hole of the connecting member is threadedly connected to the installation portion of the vehicle. Therefore, the vehicle sensor can be fixed in the vehicle through the connecting member. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] To make the purpose, technical solutions and advantages of the present utility model clearer, the implementation manners of the present utility model will be further described in detail below with reference to the drawings.

[0061] Refer to Figure 1 and Figure 2, an embodiment of the present application provides an automotive sensor 1, and the automotive sensor 1 includes a sensor body 2 and a fixing portion 3. Along the first direction X, the sensor body 2 has an upper surface 21, and the fixing portion 3 is provided on the upper surface 21 of the sensor body 2. The fixing portion 3 is integrally formed with the sensor body 2, and the fixing portion 3 is rectangular in shape.

[0062] As Figures 1 to 3b shown, the fixing portion 3 includes a receiving cavity 31 and an elastic connecting member 32. Along the second direction Y, one end of the receiving cavity 31 has a first opening 311, and the first opening 311 is rectangular in shape. Along the first direction X, the first opening 311 has a first height h1, and the second direction Y is perpendicular to the first direction X.

[0063] Continue to refer to Figures 1 to 3b , the elastic connecting member 32 is disposed in the receiving cavity 31. Along the first direction X, the elastic connecting member 32 faces the upper surface 21 of the sensor body 2. The lower surface 321 of the elastic connecting member 32 has a first distance d1 from the upper surface 21 of the sensor body 2 in the first direction X, and the first height h1 is greater than the first distance d1.

[0064] Refer to Figures 1 to 4 , the first opening 311 is for inserting an external connecting member 4 into the receiving cavity 31, and after the connecting member 31 passes between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2, the connecting member 4 is fixedly connected to the elastic connecting member 32.

[0065] With the above technical solution, when it is necessary to install and fix the automotive sensor 1 in a vehicle, an operator inserts the connecting member 4 into the receiving cavity 31 of the fixing portion 3 of the automotive sensor 1. Subsequently, after the connecting member 4 passes between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2, the connecting member 4 is fixedly connected to the elastic connecting member 32 of the fixing portion 3. Subsequently, the operator can install and fix the other end of the connecting member 4 in the vehicle.

[0066] Since the first opening 311 of the receiving cavity 31 of the fixing portion 3 has a first height h1, and the lower surface 321 of the elastic connecting member 32 of the fixing portion 3 has a first distance d1 from the upper surface 21 of the sensor body 2, and the first height h1 is greater than the first distance d1, when the connecting member 4 passes between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2, the connecting member 4 will squeeze the elastic connecting member 32, causing the elastic connecting member 32 to deform upward. After the connecting member 4 passes between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2, the elastic connecting member 32 returns to its original state downward, and the connecting member 4 is fixedly connected to the elastic connecting member 32.

[0067] When it is necessary to remove the vehicle sensor 1 from the vehicle, the operator first removes the other end of the connecting member 4 from the vehicle, and then deforms the elastic connecting member 32 upward to increase the first distance d1, so that the connecting member 4 passes through between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2 and exits from the accommodation cavity 31 of the fixing portion 3, completing the disassembly. When it is necessary to install and fix the vehicle sensor 1 in the vehicle next time, just repeat the above steps.

[0068] In addition, the fixing portion 3 and the sensor body 2 are integrally formed. Therefore, when manufacturing the mold for the vehicle sensor 1, only one mold needs to be produced, reducing the production cost.

[0069] It should be noted that the shape of the fixing portion 3 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the shape of the fixing portion 3 can be circular, pentagonal, etc. The shape of the first opening 311 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the shape of the first opening 311 can be square, trapezoidal, etc., as long as the connecting member 4 can be inserted into the accommodation cavity 31.

[0070] In some possible implementation manners, referring to Figure 1 and Figure 2 , the vehicle sensor 1 includes a pressure pipe (not shown in the figure). Along the second direction Y, one end of the sensor body 2 is provided with a connecting portion 22. The connecting portion 22 and the first opening 311 of the accommodation cavity 31 are located on the same side, and the connecting portion 22 is in interference fit connection with the pressure pipe.

[0071] Adopting the above technical solution, the pressure pipe and the first opening 311 of the accommodation cavity 31 are located on the same side, avoiding damage to the connecting portion 22 of the sensor body 2 caused by the bending requirement of the pressure pipe.

[0072] In some possible implementation manners, referring to Figure 1 and Figure 2 , the accommodation cavity 31 has a first cavity wall 312, a second cavity wall 313 and a third cavity wall 314. Along the second direction Y, the first cavity wall 312 and the elastic connecting member 32 are opposite and spaced apart. Along the third direction Z, the second cavity wall 313 and the third cavity wall 314 are opposite and spaced apart.

[0073] Referring to Figure 2 , Figure 3b , Figures 5 to 6bThe automotive sensor 1 further includes a connector 4, which includes a first portion 44 and a second portion 45. The first portion 44 extends along the first direction X, and the second portion 45 extends along the second direction Y. The connector 4 has an insertion end 41. Along the first direction X, the insertion end 41 has a second height h2, and the second height h2 is greater than the first distance d1. Along the second direction Y, one end of the insertion end 41 abuts against one end of the elastic connector 32, and the other end of the insertion end 41 abuts against the first cavity wall 312 of the accommodating cavity 31. Along the third direction Z, both ends of the insertion end 41 abut against the second cavity wall 313 and the third cavity wall 314 of the accommodating cavity 31, respectively. The third direction Z is perpendicular to the first direction X.

[0074] With the above technical solution, the insertion end 41 of the connector 4 has a second height h2, the lower surface 321 of the elastic connector 32 of the fixing portion 3 has a first distance d1 from the upper surface 21 of the sensor body 2, and the second height h2 is greater than the first distance d1.

[0075] Therefore, after the connecting member 4 passes through the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2, along the second direction Y, one end of the insertion end 41 of the connecting member 4 abuts against one end of the elastic connecting member 32, and the other end of the insertion end 41 abuts against the first cavity wall 312 of the accommodating cavity 31, that is, in the second direction Y, the elastic connecting member 32 and the first cavity wall 312 of the accommodating cavity 31 jointly clamp the insertion end 41.

[0076] Along the third direction Z, the two ends of the insertion end 41 are respectively in contact with the second cavity wall 313 and the third cavity wall 314 of the accommodating cavity 31, that is, in the third direction Z, the second cavity wall 313 and the third cavity wall 314 of the accommodating cavity 31 jointly clamp the insertion end 41. That is, in the second direction Y, the first cavity wall 312 of the accommodating cavity 31 and the elastic connector 32 limit the insertion end 41 of the connector 4, and in the third direction Z, the second cavity wall 313 and the third cavity wall 314 of the accommodating cavity 31 limit the insertion end 41 of the connector 4, so that the connector 4 and the elastic connector 32 can be fixedly connected and will not shake due to the bumps of the vehicle body during driving.

[0077] It should be noted that the embodiment of the present application does not impose any specific limitation on the shape of the connector 4. For example, in other possible implementations, the shape of the connector 4 may be composed of three parts, four parts, etc. The shape of the connector 4 is determined by actual conditions.

[0078] In some possible implementations, reference Figures 5 to 6b, the connecting member 4 has a first through hole 42 which is rectangular in shape. Along the second direction Y, the first through hole 42 is located on the right side of the insertion end 41. After the connecting member 4 abuts against the elastic connecting member 32, the first through hole 42 is used to accommodate the elastic connecting member 32. Along the second direction Y, the first through hole 42 has a first length l1, and the elastic connecting member 32 has a second length l2, and the first length l1 is greater than the second length l2.

[0079] Adopting the above technical solution, after the connecting member 4 passes through between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2, the elastic connecting member 32 returns to its original state, and the elastic connecting member 32 is embedded into the first through hole 42 of the connecting member 4.

[0080] When it is necessary to disconnect the vehicle sensor 1 from the connecting member, the operator deforms the elastic connecting member 32. Since the first length l1 of the first through hole 42 of the connecting member 4 is greater than the second length l2 of the elastic connecting member 32, therefore, there is enough space in the second direction Y to deform the elastic connecting member 32 so that the connecting member 4 passes through between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2 and exits from the accommodation cavity 31 of the fixing portion 3 to complete the disassembly.

[0081] In some possible implementation manners, referring to Figures 1 to 3b , the fixing portion 3 has a convex portion 33 which is rectangular in shape. Along the third direction Z, the convex portion 33 is respectively spaced from the second cavity wall 313 and the third cavity wall 314 of the accommodation cavity 31. Along the second direction Y, one end of the convex portion 33 is connected to the elastic connecting member 32, and the other end of the convex portion 33 is spaced from the first cavity wall 312 of the accommodation cavity 31. Along the first direction X, the convex portion 33 is spaced from the upper surface 21 of the sensor body 2.

[0082] As Figure 5 shown, after the connecting member 4 abuts against the elastic connecting member 32, along the first direction X, the lower surface of the convex portion 33 abuts against the upper surface of the insertion end 41 of the connecting member 4.

[0083] Adopting the above technical solution, when it is necessary to fixedly connect the vehicle sensor 1 to the connecting member 4, the connecting member 4 passes through between the lower surface 321 of the elastic connecting member 32 and the upper surface 21 of the sensor body 2. The connecting member 4 abuts against the elastic connecting member 32 of the fixing portion 3. The convex portion 33 of the fixing portion 3 is located above the connecting member 4. The convex portion 33 of the fixing portion 3 presses the connecting member 4 to give the connecting member 4 a downward pressure in the first direction X, so that the connecting member 4 and the convex portion 33 of the fixing portion 3 can be fixedly connected.

[0084] Combined with the above, in the second direction Y, the first cavity wall 312 of the accommodating cavity 31 and the elastic connecting member 32 limit the insertion end 41 of the connecting member 4; in the third direction Z, the second cavity wall 313 and the third cavity wall 314 of the accommodating cavity 31 limit the insertion end 41 of the connecting member 4; in the first direction X, the convex portion 33 of the fixing portion 3 applies a downward pressure to the connecting member 4 to press the connecting member 4. Therefore, in the first direction X, the second direction Y and the third direction Z, the insertion end 41 of the connecting member 4 is fully limited, ensuring that the connecting member 4 and the automotive sensor 1 can be fixedly connected and will not shake due to the bumps of the vehicle body during driving.

[0085] When it is necessary to disconnect the automobile sensor 1 from the connector 4, the operator applies an upward force in the first direction X to the connector 33 by prying the protrusion 33 of the fixing portion 3, thereby deforming the elastic connector 32, so that the connector 4 passes through between the lower surface 321 of the elastic connector 32 and the upper surface 21 of the sensor body 2, and withdraws from the accommodating cavity 31 of the fixing portion 3, thereby completing the disassembly.

[0086] It should be noted that the embodiment of the present application does not impose any specific limitation on the shape of the protrusion 33. For example, in other possible implementations, the shape of the protrusion 33 may be a triangle, a semicircle, etc.

[0087] In some possible implementations, reference Figure 1 and Figure 3b A second distance d2 is formed between the lower surface of the protrusion 33 and the upper surface 21 of the sensor body 2 in the first direction X, and the second distance d2 is greater than the first distance d1.

[0088] By adopting the above technical solution, when the automobile sensor 1 needs to be fixedly connected to the connector 4, the lower surface of the convex portion 33 of the fixing portion 3 and the upper surface 21 of the sensor body 2 have a second distance d2 in the first direction X, and the lower surface 321 of the elastic connector 32 of the fixing portion 3 and the upper surface 21 of the sensor body 2 have a first distance d1, and the second distance d2 is greater than the first distance d1, that is, the convex portion 33 of the fixing portion 3 and the elastic connector 32 of the fixing portion 3 have a height difference in the first direction X. Therefore, after the connector 4 passes through between the lower surface 321 of the elastic connector 32 and the upper surface 21 of the sensor body 2, one end of the insertion end 41 of the connector 4 can abut against one end of the elastic connector 32.

[0089] In addition, along the first direction X, the insertion end 41 has a second height h2, and the second distance d2 is equal to the second height h2. Therefore, the convex portion 33 of the fixing portion 3 presses against the connecting member 4, applying a downward pressure to the connecting member 4 in the first direction X, so that the connecting member 4 and the convex portion 33 of the fixing portion 3 can be fixedly connected, and there will be no shaking due to the bumping of the vehicle body during the driving of the vehicle.

[0090] It should be noted that the present application embodiment does not specifically limit the magnitude relationship between the second distance d2 and the second height h2. For example, in other possible implementation manners, the second distance d2 may be slightly greater than the second height h2, or the second distance d2 may be slightly less than the second height h2.

[0091] In some possible implementation manners, referring to Figure 1 、 Figure 2 and Figure 4 , along the first direction X, one end of the receiving cavity 31 has a second opening 315, and the second opening 315 is in a "U shape". The second opening 315 exposes the convex portion 33 of the fixing portion 3, and the second opening 315 faces the upper surface 21 of the sensor body 2.

[0092] With the above technical solution, through the second opening 315 of the receiving cavity 31, it is possible to observe whether the connecting member 4 is fixedly connected to the elastic connecting member 32 of the fixing portion 3 in place.

[0093] It should be noted that the present application embodiment does not specifically limit the shape of the second opening 315. For example, in other possible implementation manners, the shape of the second opening 315 may be semi-circular, irregular, etc., as long as it is possible to observe whether the connecting member 4 is fixedly connected to the elastic connecting member 32 of the fixing portion 3 in place.

[0094] Referring to Figure 2 and Figure 4 , the present application embodiment also provides an automobile (not shown in the figure), which includes a mounting portion (not shown in the figure) and two symmetrically arranged automobile sensors 1 as described in any one of the foregoing. The two automobile sensors 1 are connected by a pressure pipe. The elastic connecting member 32 of the automobile sensor 1 is fixedly connected to the connecting member 4, and the other end of the connecting member 4 is connected to the mounting portion.

[0095] In some possible implementation manners, the other end of the connecting member 4 has a second through hole 43, and the second through hole 43 is circular. The second through hole 43 is threadedly connected to the mounting portion.

[0096] With the above technical solution, one end of the insertion end 41 of the connecting member 4 abuts against one end of the elastic connecting member 32, the convex portion 33 of the fixing portion 3 is located above the connecting member 4, and the convex portion 33 of the fixing portion 3 presses the connecting member 4, so that the fixing portion 3 is fixedly connected to the connecting member 4. The second through hole 43 of the connecting member 4 is threadedly connected to the mounting portion of the vehicle. Therefore, the vehicle sensor 1 can be fixed in the vehicle through the connecting member 4.
