Description

Technical Field

[0001] The utility model relates to the field of angle sensor installation, in particular to an angle sensor welding structure and an automobile electric actuator. Background Art

[0002] Angle sensors have been widely used in various industrial fields. For example, they are used to sense the angle changes of accelerator pedals, brake pedals, and clutch pedals in automobile control systems.

[0003] The existing angle sensor can be found in the patent application number CN201610803020.1, which is a Hall-type angle sensor. This type of angle sensor needs to be welded on a circuit board, and the shaft of the angle to be monitored is passed through the shaft hole of the angle sensor. Thus, the angle information of the shaft can be fed back to the controller in the form of an electrical signal through the angle sensor. However, when the shaft deviates, since the angle sensor is fixed on the circuit board, the shaft hole of the angle sensor cannot deviate with the shaft, which leads to internal damage to the angle sensor.

[0004] Therefore, how to avoid damage to the angle sensor after the shaft is offset is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the utility model is to overcome the above technical deficiencies, propose an angle sensor welding structure, and solve the technical problem in the prior art of how to avoid damage to the angle sensor after the shaft is offset.

[0006] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0008] A base plate, comprising a plurality of receiving portions;

[0009] A connecting plate, comprising a base and a plurality of connecting arms corresponding to the plurality of receiving portions one by one, the base having a plurality of first pads welded to the angle sensor pins, one end of the connecting arm connected to the base, and the other end having a second pad, the second pad being welded to the receiving portion, and the plurality of the second pads being electrically connected to the plurality of the first pads corresponding to each other;

[0010] Wherein, the connecting arm can be bent and deformed.

[0011] In some embodiments, the connecting arm is in the shape of an arc surrounding the axis of the angle sensor.

[0012] In some embodiments, there are three connecting arms, and the angles between the connecting arms are 120°.

[0013] In some embodiments, the substrate is provided with a first matching hole, the base is provided with a second matching hole, and the first matching hole and the second matching hole are coaxially arranged and docked with the axial hole of the angle sensor.

[0014] In some embodiments, the receiving portion includes a welding column, the second welding pad is provided with an inserting hole, and the welding column is passed through the inserting hole.

[0015] In some embodiments, the substrate is a PCB substrate.

[0016] In some embodiments, the connecting board is an FPC connecting board.

[0017] In some embodiments, the base is in contact with the substrate.

[0018] In some embodiments, the contact surface between the substrate and the base has a first protective layer, and the contact surface between the base and the substrate has a second protective layer.

[0019] In a second aspect, the utility model further provides an automotive electric actuator, comprising the above-mentioned angle sensor welding structure.

[0020] First, each pin of the angle sensor is welded to the first pad one by one, so that the angle sensor is installed on the base. Since the supporting part and the second pad are welded to each other, and the second pads are electrically connected to the first pads one by one, the angle sensor and the receiving part are electrically connected to each other, thereby completing the installation of the angle sensor. When the coaxiality of the output rotating shaft of the gear is offset, the base can be translated because the connecting arm can be bent and deformed, and the angle sensor can be offset with the output rotating shaft of the gear, thereby avoiding the problem of damage to the rotating shaft and internal structure of the angle sensor.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problem of how to avoid damage to the angle sensor after the rotating shaft is offset, the utility model provides an angle sensor welding structure, which can adapt to the position change of the gear output rotating shaft to avoid damage to the rotating shaft and internal structure of the angle sensor.

[0026] It should be noted that the angle sensor welding structure of the present invention is used for but not limited to automotive electric actuators, etc. For the sake of convenience of explanation, in the present invention, only the application of the angle sensor welding structure to the automotive electric actuator is used as an example for explanation. The principle of applying the angle sensor welding structure to other types of equipment is essentially the same as the principle applied to the automotive electric actuator, which will not be elaborated here.

[0027] See also Figure 1 , Figure 1 This is a structural schematic diagram of an angle sensor welding structure in an embodiment of the utility model. The angle sensor welding structure includes a substrate 100 and a connecting plate 200. The substrate 100 includes a plurality of receiving portions 110. The connecting plate 200 includes a base 210 and a plurality of connecting arms 220 corresponding one-to-one to the plurality of receiving portions 110. The base 210 has a plurality of first solder pads 211 soldered to the angle sensor pins. One end of the connecting arm 220 is connected to the base 210, and the other end thereof has a second solder pad 221. The second solder pad 221 is soldered to the receiving portion 110, and the plurality of second solder pads 221 are electrically connected one-to-one to the plurality of first solder pads 211, wherein the connecting arm 220 can be bent and deformed.

[0028] In this embodiment, first, each pin of the angle sensor is welded to the first pad 211 one by one, so that the angle sensor is installed on the base 210. Since the supporting part and the second pad 221 are welded to each other, and the second pads 221 are electrically connected to the first pads 211 one by one, the angle sensor and the receiving part 110 are electrically connected to each other, thereby completing the installation of the angle sensor. When the coaxiality of the axial hole of the angle sensor and the output rotating shaft of the gear is offset, since the connecting arm 220 can be bent and deformed, the base 210 can be offset with the angle sensor, thereby avoiding the problem of damage to the rotating shaft and internal structure of the angle sensor.

[0029] In some embodiments, the connecting arm 220 is in the shape of an arc surrounding the axis of the angle sensor.

[0030] In this embodiment, since the connecting arm 220 is in an arc shape surrounding the angle sensor, when the base 210 is offset with the angle sensor, the connecting arm 220 is bent instead of stretched and compressed, thereby preventing the connecting arm 220 from being damaged.

[0031] In some embodiments, there are three connecting arms 220 , and the angles between the connecting arms 220 are all 120°.

[0032] In this embodiment, the three connecting arms 220 are evenly distributed, so when the base 210 deviates with the angle sensor, it can prevent a certain connecting arm 220 from bending too much.

[0033] In some embodiments, the substrate 100 is provided with a first matching hole 120 , and the base 210 is provided with a second matching hole 213 . The first matching hole 120 and the second matching hole 213 are coaxially arranged and docked with the axial hole of the angle sensor.

[0034] In this embodiment, the gear output rotating shaft can pass through the first matching hole 120 and the second matching hole 213 after being inserted into the shaft hole.

[0035] In some embodiments, the receiving portion 110 includes a welding column 111 , the second welding pad 221 defines an inserting hole 2211 , and the welding column 111 passes through the inserting hole 2211 .

[0036] In this embodiment, since the inserting hole 2211 is sleeved on the welding column 111, the receiving portion 110 and the second welding pad 221 are more stably connected to each other.

[0037] In some embodiments, the substrate 100 is a PCB substrate.

[0038] In some embodiments, the connecting board 200 is an FPC connecting board.

[0039] In some embodiments, the base 210 is in contact with the substrate.

[0040] In this embodiment, since the base 210 is attached to the substrate 100 , the base 210 can be used to support the substrate 100 .

[0041] In some embodiments, the contact surface between the substrate 100 and the base 210 has a first protective layer, and the contact surface between the base 210 and the substrate 100 has a second protective layer.

[0042] In this embodiment, the first protective layer and the second protective layer can prevent the substrate 100 and the base 210 from being worn.

[0043] In addition, the utility model also provides an automobile electric actuator, comprising the above-mentioned angle sensor welding structure.

[0044] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0045] Each pin of the angle sensor is welded to the first pad 211 one by one, so that the angle sensor is installed on the base 210. Since the supporting part and the second pad 221 are welded to each other, and the second pads 221 are electrically connected to the first pads 211 one by one, the angle sensor and the receiving part 110 are electrically connected to each other, thereby completing the installation of the angle sensor. When the coaxiality of the axial hole of the angle sensor and the output rotating shaft of the gear is offset, since the connecting arm 220 can be bent and deformed, the base 210 can be offset with the angle sensor, so that the angle sensor can adapt to the position change of the output rotating shaft of the gear, avoiding the problem of damage to the rotating shaft and internal structure of the angle sensor.

[0046] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
