Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to a wire harness fixing assembly, a motor end cover, and a motor. Background Technology

[0002] As is well known, an electric motor, especially a vehicle drive motor, includes, for example, a motor end cover (i.e., a non-drive end cover, i.e., an NDE end cover), a motor shaft, a motor rotor, and a motor stator. The operation of the motor causes a temperature change in the motor stator, and a temperature sensor can be attached to the motor stator to detect the stator temperature and generate an electrical signal representing the temperature. A first wiring harness electrically connected to the temperature sensor needs to extend through the motor end cover and be electrically connected to an electrical connector to transmit the electrical signal representing the temperature. Additionally, an electromagnetic sensor is configured to detect the position and / or speed of the motor shaft and generate an electrical signal representing the position and / or speed of the motor shaft. A second wiring harness electrically connected to the electromagnetic sensor also needs to extend through the motor end cover and be electrically connected to an electrical connector to transmit the electrical signal representing the position and / or speed of the motor shaft.

[0003] In some cases, the redundant length of the wiring harness (i.e., the first wiring harness and / or the second wiring harness) may be large. If the redundant length of the wiring harness is repeatedly bent to reassemble the wiring harness, it is easy to damage the wiring harness. Alternatively, if the redundant length of the wiring harness is allowed to be arranged in a disordered manner, it is easy to cause physical interference between the wiring harness and the sensor rotor of the electromagnetic sensor, thereby causing damage to the wiring harness, as well as sensor rotor, or even motor failure.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] As is well known, an electric motor, especially a vehicle drive motor, includes a motor housing and other motor components housed within the motor housing. These other motor components include a motor shaft, a motor rotor that is torsionally connected to the motor shaft, and a motor stator mounted around the motor rotor on the inner side of the motor housing. The operation of the motor causes a change in the temperature of the motor stator (e.g., a rise in temperature). A temperature sensor (also known as a first sensor), such as a platinum resistance temperature sensor, can be attached to the motor stator to detect the temperature of the motor stator and generate an electrical signal representing the temperature.

[0033] The motor housing includes a drive end cover and a non-drive end cover (i.e., NDE end cover) that is opposite to the drive end cover (i.e., DE end cover) along the longitudinal axis of the motor housing, wherein the motor shaft extends from the DE end cover. Figure 1 and Figure 2As shown, for example, the motor end cap 10 of the NDE end cap may include: a first body 12 defining a central opening 14 for housing an electromagnetic sensor 28, such as a rotary transformer (which may also be referred to as a second sensor, especially such as...). Figure 2 (As shown); an outer circumferential flange 16 and an inner circumferential flange 18 extending axially relative to the first body 12 around the central opening 14, away from the inner side of the motor housing, wherein the diameter of the outer circumferential flange 16 is larger than the diameter of the inner circumferential flange 18; and a plurality of connecting ribs 24 extending radially between the outer circumferential flange 16 and the inner circumferential flange 18. The motor end cover 10 may also include a through hole 20 through the first body 12 (especially as shown). Figure 1 As shown), the through hole 20 is located between the outer circumferential flange 16 and the inner circumferential flange 18 and avoids the plurality of connecting ribs 24, for power supply connection to the first wiring harness 22 of the temperature sensor (especially as shown). Figure 2 (As shown) The first wiring harness 22 extends from the inside to the outside of the motor housing through the through-hole 20. After extending from the inside to the outside of the motor housing through the through-hole 20, it needs to be electrically connected to the electrical connector 26 (especially as shown). Figure 2 As shown), to transmit an electrical signal representing temperature to electrical connector 26.

[0034] As is well known, an electromagnetic sensor includes a sensor support frame, a sensor stator, and a sensor rotor, with the sensor stator mounted to the sensor support frame around the sensor rotor. The sensor rotor is torsionally connected, for example, to an interference fit to a motor shaft. When the sensor rotor rotates together with the motor shaft, the sensor stator detects the position and / or velocity of the sensor rotor based on electromagnetic induction, and thus detects the position and / or velocity of the motor shaft, generating an electrical signal representing the position and / or velocity of the motor shaft. (Continuing to the previous section...) Figure 2 An electromagnetic sensor 28 is inserted into the central opening 14 so that the sensor support is connected to the motor end cover 10. In this case, the sensor rotor is actually very close to the axial end face of the inner circumferential flange 18. A second wiring harness 38 electrically connected to the electromagnetic sensor 28 extends from the central opening 14 via the motor end cover 10 and also needs to be electrically connected to the electrical connector 26 to transmit electrical signals indicating the position and / or speed of the motor shaft.

[0035] The motor also includes a sensor end cover 30 mounted on the motor end cover 10 (for clarity, in...). Figure 2In the diagram (where the motor end cover 10 and sensor end cover 30 are shown separately), the sensor end cover 30 includes a second body 32 and a circumferential flange 34 extending radially outward from the second body 32, for example. The circumferential flange 34 has a plurality of through holes. The sensor end cover 30 is configured to be connected to the motor end cover 10 by means of a plurality of bolts 37, for example, through the plurality of through holes on the circumferential flange 34 and a plurality of corresponding threaded holes 39 on the outer circumferential flange 16 of the motor end cover 10, such that the motor end cover 10 and the sensor end cover 30 together define an internal space. The electrical connector 26 includes a first port 35 and a second port 36 opposite to the first port 35, while the sensor end cover 30 has an electrical connector housing 33 integrated into the second body 32. The electrical connector housing 33 defines a receiving cavity for receiving the electrical connector, and an electrical contact element is provided in the receiving cavity. When the sensor end cap 30 is connected to the motor end cap 10, the electrical connector 26 is housed in the receiving cavity, wherein the first port 35 of the electrical connector 26 faces the internal space so that the first wire harness 22 and / or the second wire harness 38 can be electrically connected to the first port 35 of the electrical connector 26, and the second port 36 of the electrical connector 26 is electrically connected to the electrical contact member to continue transmitting electrical signals indicating temperature and electrical signals indicating the position and / or speed of the motor shaft.

[0036] This utility model provides a wiring harness fixing assembly configured for a motor end cover 10, which arranges a first wiring harness 22 and / or a second wiring harness 38 in an orderly and space-saving manner within the internal space. For example... Figure 2 , Figure 3 and Figure 4 As shown, the wiring harness fixing assembly includes: a generally annular guide ring 42, the guide ring 42 including a first end face 44 facing away from the motor end cover 10 in the connected state, and a second end face 46 opposite to the first end face 44 along the central axis L1 of the guide ring 42 and facing the motor end cover 10 in the connected state, wherein the first end face 44 defines a generally annular travel path around the central axis L1 (e.g., ... Figure 3 (as shown by the dashed line in the diagram) and configured to guide the first harness 22 and / or the second harness 38 to extend along the travel path, for example, the first harness 22 and / or the second harness 38 may extend along the travel path abutting the first end face 44.

[0037] Especially Figure 2As shown, the first wire harness 22, after extending through the through-hole 20, reaches the first starting position of the guide ring 42 (which is blocked by the electrical connector 26), and then extends counterclockwise along at least a portion of the travel path. The first wire harness 22 then leaves the guide ring 42 from its first ending position P1 (i.e., no longer extends along the travel path) to continue extending and electrically connecting to the first port 35 of the electrical connector 26. In contrast, the second wire harness 38, after extending through the central opening 14, reaches the second starting position S2 of the guide ring 42, and then extends clockwise along at least a portion of the travel path. The second wire harness 38 may meet the first wire harness 22 on the travel path and extend at least partially in parallel to make full use of the travel path to arrange the first wire harness 22 and the second wire harness 38 in an orderly and space-saving manner. The second wire harness 38 then bends approximately 180 degrees from the second ending position P2 of the guide ring 42 to leave the guide ring 42 (i.e., no longer extends along the travel path), thus returning until it reaches and electrically connects to the first port 35 of the electrical connector 26. It is understandable that, depending on the specific application, a different travel path can be used. Figure 2 The extension configuration shown is a first harness 22 and a second harness 38.

[0038] Continue to refer to Figure 2 The guide ring 42 further includes a plurality of wire harness clamps 45 configured to hold a first wire harness 22 and / or a second wire harness 38 extending along a travel path on the guide ring 42 at a plurality of first locations on the guide ring 42, for example, clamping it on a first end face 44. A plurality of connecting members 50 (e.g., studs) may be provided to connect the guide ring 42 to the motor end cover 10 at a plurality of second locations on the guide ring 42, for example, to the axial end face of the inner circumferential flange 18.

[0039] Especially Figure 4 As shown, the wire harness fixing assembly includes a spacer 48 extending from a second end face 46, for example, parallel to the central axis L1, at each of the plurality of second positions. The spacer 48 forms a channel 51 for receiving the connecting member 50 (e.g., Figure 3 As shown, when the connecting component 50 passes through the channel 51 to connect the guide ring 42 to the motor end cover 10, the spacer 48 ensures that the second end face 46 is spaced apart from the motor end cover 10 along the central axis L1. Thus, the first wiring harness 22 and / or the second wiring harness 38 extending along the travel path can be further moved away from the sensor rotor, which is very close to the axial end face of the inner circumferential flange 18, to avoid physical interference with the sensor rotor. For example, if the distance between the first wiring harness 22 and / or the second wiring harness 38 and the sensor rotor is too close, the rotation of the sensor rotor may cause the first wiring harness 22 and / or the second wiring harness 38 to become entangled with the sensor rotor, which may further cause damage to the wiring harness and failure of the sensor rotor or even the motor.

[0040] It is understood that, in addition to the motor end cover 10, the wiring harness fixing assembly can also be configured for use with other types of fittings, and the spacer 48 is configured such that, when the wiring harness fixing assembly is connected to the fitting, the second end face 46 is spaced apart from the fitting along the central axis L1.

[0041] like Figure 5 As shown, for example, at least one of the plurality of wire harness clamps 45 is configured as a first resilient clamp separable from the guide ring 42, the two ends of the first resilient clamp defining a first opening 47 such that the first resilient clamp is, for example, similar to a C-shape, and the opening spacing of the first opening 47 in its natural state is significantly smaller than the radial dimension of the guide ring 42 at its plurality of first positions. Therefore, in combination Figure 5 and Figure 6 The operator can first operate the first wiring harness 22 and / or the second wiring harness 38 with one hand to extend along the travel path, and when the first wiring harness 22 and / or the second wiring harness 38 passes through one of the plurality of first positions, apply external force with the other hand to open the first opening 47 of the first elastic clamping ring, such that the opening spacing of the first opening 47 is greater than the radial dimension of the guide ring 42 at one of the plurality of first positions under external force. Thus, the first elastic clamping ring can pass through the first end face 44 substantially perpendicular to the travel path via the first opening 47 until the two ends of the first elastic clamping ring are firmly abutted against at least a portion of the second end face 46 via the gap between the second end face 46 and the motor end cover 10, thereby clamping the first wiring harness 22 and / or the second wiring harness 38 on the first end face 44 at one of the plurality of first positions. It is understood that the first opening 47 can be stretched to a certain extent while the first elastic clamping ring is holding the first wire harness 22 and / or the second wire harness 38, so that the opening spacing of the first opening 47 is greater than the opening spacing of the first opening 47 in its natural state.

[0042] Supplementary or alternative, such as Figure 2 As shown, at least one of the plurality of wire harness clamps 45 is configured as a flexible cable tie separable from the guide ring 42. It is well known that one end of the flexible cable tie has a serrated portion and the other end has a small hole with a locking buckle. An operator can pass one end of the flexible cable tie substantially perpendicularly to the travel path through the gap between the second end face 46 and the motor end cover 10 until it reaches the first end face 44. Then, the operator can pass one end of the flexible cable tie through the small hole to the other end of the flexible cable tie. Finally, the operator can tighten the flexible cable tie through one end, and the locking buckle will automatically engage the serrated portion to ensure that the flexible cable tie securely clamps the first wire harness 22 and / or the second wire harness 38 onto the first end face 44 at one of the plurality of first positions.

[0043] Optionally, such as Figure 3 and Figure 6 As shown, the guide ring 42 may include at least one radial groove at at least one of the plurality of first positions for positioning the first resilient clamp and / or flexible cable tie. For example, the guide ring 42 includes a first inner periphery 44a and a first outer periphery 44b defining a first end face 44, and the guide ring 42 also includes a second inner periphery 46a and a second outer periphery 46b defining a second end face 46. For example, an outer circumferential surface 56 extending from the first outer periphery 44b to the second outer periphery 46b is radially recessed toward the travel path at at least one of the plurality of first positions to form an outer radial groove 52 (especially as shown in the figure). Figure 3 (As shown). Alternatively or supplementarily, the inner circumferential surface 58 extending from the first inner periphery 44a to the second inner periphery 46a is recessed radially outward toward the path of travel at at least one of the plurality of first locations to form an inner radial groove 54 (especially as shown). Figure 3 (As shown). That is to say, the outer radial groove 52 and the inner radial groove 54 can be radially opposite.

[0044] The circumferential dimensions of the outer radial groove 52 and / or the inner radial groove 54 will be greater than the corresponding width of the first elastic clamping ring, so that the first elastic clamping ring can pass over the first end face 44, pass over the outer radial groove 52 and / or the inner radial groove 54, and abut against at least a portion of the second end face 46 to fix the first elastic clamping ring in place via the outer radial groove 52 and / or the inner radial groove 54.

[0045] Similarly, the circumferential dimensions of the outer radial groove 52 and / or the inner radial groove 54 will be greater than the corresponding width of the flexible cable tie, so that the first elastic clamp can pass over and abut against the second end face 46, pass over the outer radial groove 52 and / or the inner radial groove 54, and pass over the first end face 44, so as to secure the flexible cable tie in place via the outer radial groove 52 and / or the inner radial groove 54.

[0046] Optionally, especially as Figure 6 As shown, at least for the outer radial groove 52 (if any), the diameter of the first outer periphery 44b can be larger than the diameter of the second outer periphery 46b, such that the outer circumferential surface 56 is radially inward from the first end face 44 toward the second end face 46. Similarly, at least for the inner radial groove 54 (if any), the diameter of the first inner periphery 44a can be smaller than the diameter of the second inner periphery 46a, such that the inner circumferential surface 58 is radially outward from the first end face 44 toward the second end face 46. This facilitates the smooth entry of the two ends of the first resilient clamp into the gap between the second end face 46 and the motor end cover 10 via the outer circumferential surface 56 and securely abuts against at least a portion of the second end face 46.

[0047] like Figure 7As shown, at least one of the plurality of wire harness clamps 45 may alternatively or additionally be configured as a second resilient clamp that is inseparable from the guide ring 42, i.e., connected to or integrally formed with the guide ring 42, the guide ring 42 being formed as part of the second resilient clamp, the two ends of the second resilient clamp defining second openings 60 such that the second resilient clamp is, for example, C-shaped, the second openings 60 being opposite to the first end face 44, and the opening spacing of the second openings 60 in their natural state may be less than the diameter of the first wire harness 22 and / or the second wire harness 38. Therefore, the operator can first manipulate the first wire harness 22 and / or the second wire harness 38 to extend along the travel path, and when the first wire harness 22 and / or the second wire harness 38 encounters the second resilient clamp, the first wire harness 22 and / or the second wire harness 38 enters the second resilient clamp via the second openings 60.

[0048] It is understood that the number of each of the plurality of first positions and the plurality of second positions and their distribution on the travel path can be set based on the specific application.

[0049] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
