Description

Technical Field

[0001] This application belongs to the field of new energy vehicle technology, and more specifically, relates to a drive motor temperature monitoring device and a vehicle. Background Technology

[0002] The drive motor of an electric vehicle generates a lot of heat during operation. If the temperature of the drive motor is too high, it will cause problems such as deterioration of the drive motor performance, aging of insulation materials, or even burnout. Therefore, a temperature monitoring device is often installed on the drive motor to monitor the temperature of the drive motor in real time. The temperature monitoring device senses the temperature of the drive motor by contacting the monitoring probe with the drive motor body.

[0003] However, during actual operation, the drive motor will vibrate at high frequency, which will also cause the monitoring probe and connecting wire of the monitoring device to vibrate at high frequency. The vibration will cause the connecting wire and monitoring probe to become loose or worn, which will lead to poor contact between the monitoring probe and the drive motor, affecting the accuracy of data monitoring. Furthermore, long-term use may cause signal transmission interruption. Utility Model Content

[0004] The purpose of this application is to provide a drive motor temperature monitoring device and a vehicle, aiming to solve the technical problem that existing temperature monitoring devices are prone to loosening and wear under high-frequency vibration of the drive motor, which affects the accuracy and continuity of temperature monitoring data.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a drive motor temperature monitoring device is provided, comprising: The temperature monitoring body has a bottom for fixing to the drive motor and a top connection wire with a monitoring probe at the end of the connection wire. A protective box is fixed to the temperature monitoring body and faces the temperature measuring side of the drive motor; the upper side of the protective box is provided with a wire clamping hole; and A clamping assembly is disposed inside the protective box; the clamping assembly has a clamping head hole that runs vertically through the box; the side of the clamping head hole facing the drive motor has a notch that runs through to the inner wall of the protective box; The connecting wire passes downward through the clamping hole so that the monitoring probe extends into the protective box and is clamped in the clamping hole.

[0006] Compared with the prior art, the solution shown in this application embodiment is provided with a wire clamping hole and a clamping head hole. The wire clamping hole is used to clamp the connecting wire to realize the limiting of the connecting wire, and the clamping head hole is used to clamp the monitoring probe to realize the clamping of the monitoring probe. Thus, the monitoring probe can be limited and clamped in two stages through the wire clamping hole and the clamping head hole, thereby reducing the risk of the connecting wire and the monitoring probe loosening or falling off due to the vibration of the drive motor during use. Furthermore, this application also includes a protective box. By placing the protective box on the side of the temperature monitoring body facing the drive motor, the monitoring probe can be placed inside the protective box, avoiding wear caused by direct contact between the monitoring probe and the drive motor body. Specifically, in this application, the protective box is fitted to the temperature measuring side of the drive motor, and the clamp hole has a notch extending to the inner wall of the protective box. The monitoring probe can monitor the temperature of the protective box through this notch to indirectly obtain the real-time temperature of the drive motor. Moreover, since the monitoring probe is placed inside the protective box, when the protective box vibrates with the drive motor, the relative wear between the protective box and the temperature measuring side of the drive motor replaces the wear between the monitoring probe and the temperature measuring side of the drive motor in the traditional method. Since the monitoring probe is clamped in the protective box through the clamp hole, the relative wear between the monitoring probe and the protective box is relatively smaller than the wear between the monitoring probe and the temperature measuring side of the drive motor. Therefore, the protective box can effectively reduce the impact of drive motor vibration. On the other hand, the protective box and wire clamping hole also prevent direct contact wear between the connecting wire and the drive motor, which can effectively reduce the risk of data distortion caused by the wear of the connecting wire; The drive motor temperature monitoring device provided in this application embodiment can effectively clamp and limit the connecting wire and the monitoring probe. Under the high-frequency vibration of the drive motor, it can effectively reduce the loosening and wear of the monitoring probe and improve the accuracy and continuity of temperature monitoring data.

[0007] In conjunction with the first aspect, in one possible implementation, two connecting lines are provided, each connecting line corresponding to one monitoring probe; the clamping assembly includes: A fixing block is fixed inside the protective box; Two movable blocks are symmetrically distributed on both sides of the fixed block along the first direction and are connected to the inner sidewall of the protective box. Each of the movable blocks and the fixed blocks forms a clamp hole.

[0008] By setting a fixed block and a movable block to form the aforementioned clamping hole, it is convenient to clamp the two monitoring probes; furthermore, by setting a set of fixed blocks and two movable blocks, the two monitoring probes can be clamped on both sides of the fixed block, which helps to improve the utilization rate of the fixed block and reduce the number of parts used.

[0009] In some embodiments, a plurality of first elastic members are provided between the movable block and the inner sidewall of the protective box, spaced vertically apart; wherein, when the first elastic member drives the movable block to press against the monitoring probe, the first elastic member is in a compressed state.

[0010] By incorporating a first elastic element, the movable block can move towards or away from the fixed block, thereby clamping and releasing the monitoring probe and buffering its vibration. Specifically, the first elastic element can be compressed first, moving the movable block away from the fixed block, facilitating the insertion of the monitoring probe into the clamping hole formed between the movable and fixed blocks. Then, the movable block can be released, allowing the first elastic element to relax, while still remaining compressed. Because the first elastic element has a degree of freedom in its extension and contraction along a first direction, it can buffer the vibration of the monitoring probe when the drive motor causes the temperature monitoring body to vibrate.

[0011] For example, the fixed block has a first arc surface on both sides along the first direction, and the movable block has a second arc surface on the side facing the fixed block, and both the first arc surface and the second arc surface are adapted to the outer peripheral wall of the monitoring probe.

[0012] By setting the first and second arc surfaces, the fixed block and the movable block are adapted to the outer peripheral wall of the monitoring probe, thereby ensuring the clamping effect of the fixed block and the movable block.

[0013] In conjunction with the first aspect, in one possible implementation, a limiting plate is also provided above the protective box, and a limiting hole that runs vertically through the limiting plate and the side wall of the temperature monitoring body is provided between the limiting plate and the side wall of the temperature monitoring body, and a connecting line is correspondingly limited in the limiting hole.

[0014] By setting a limiting plate, the position of the connecting line is further limited, the limiting effect of the connecting line is improved, the impact of the drive motor vibration on the connecting line is reduced, and the connection stability of the monitoring probe is ensured.

[0015] In some embodiments, the limiting plate is an arc-shaped plate, and the limiting hole is formed on the inner side of the arc-shaped plate facing the temperature monitoring body; one end of the limiting plate is hinged to the temperature monitoring body, and the other end is snapped onto the temperature monitoring body.

[0016] By setting the limiting plate as an arc-shaped plate, the inner side of the arc-shaped plate is made to fit against the outer peripheral wall of the connecting wire; by making the limiting plate and the temperature monitoring body hinged, the limiting plate can be locked and opened, making it convenient to insert the connecting wire into the corresponding limiting hole or take it out from the limiting hole.

[0017] In conjunction with the first aspect, in one possible implementation, the drive motor temperature monitoring device further includes: A fixing plate is fixed to the bottom of the temperature monitoring body; The base is fixed to the drive motor; the base is provided with two clamping parts arranged opposite to each other, and a clamping space is formed between the two clamping parts for clamping the fixing plate.

[0018] By setting a fixing plate, the temperature monitoring body is connected to the drive motor in conjunction with the base; by setting two opposite clamping parts, the fixing plate and the temperature monitoring body are effectively clamped on both sides of the fixing plate.

[0019] In some embodiments, the clamping portion includes: A connecting plate is fixed to the top of the base and extends upward; A clamping plate is slidably connected to the top of the base along the direction close to or away from the connecting plate; the clamping plate is arranged parallel to the connecting plate and located on the inner side of the connecting plate facing the fixing plate; The clamping plate is used to move away from the connecting plate so that it is clamped to the fixing plate.

[0020] By setting a clamping plate and a connecting plate, the clamping plate can be moved closer to or further away from the connecting plate. After the clamping plate moves away from the connecting plate, the clamping plate clamps the fixing plate, thereby limiting and tightening the temperature monitoring body.

[0021] For example, a plurality of second elastic members are provided between the connecting plate and the clamping plate, wherein the second elastic members are in a compressed state when the clamping plate is pressed against the fixed plate by the second elastic members.

[0022] By setting a second elastic element, the clamping plate can be moved, thereby forming an elastic buffer structure between the clamping plate and the connecting plate. When the second elastic element is in a compressed state, the fixed plate can be effectively clamped. Furthermore, when the drive motor vibrates, the second elastic element can effectively buffer the clamping plate and the connecting plate to reduce the impact of the drive motor vibration on the temperature monitoring body.

[0023] Secondly, this application also provides a vehicle including the aforementioned drive motor temperature monitoring device.

[0024] The vehicle provided in this application, by employing the aforementioned drive motor temperature monitoring device, possesses all the beneficial effects of the aforementioned drive motor temperature monitoring device. Under the high-frequency vibration of the drive motor, it can effectively reduce the loosening of the monitoring probe and the wear of the connecting wires, thereby improving the accuracy and continuity of temperature monitoring data.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] For ease of explanation, the appendix is ​​used in this application. Figure 1 and attached Figure 2 The direction indicated by the middle arrow A is used to indicate the first direction, which is the spacing direction of the two clamping holes 23.

[0032] It is important to understand that in traditional technology, the monitoring probe 12 of the temperature monitoring body 1 is directly connected to the temperature measuring device of the drive motor. Therefore, on the one hand, when the drive motor vibrates, the drive motor will cause the temperature monitoring body 1 to vibrate accordingly. However, since the vibration amplitude of the temperature monitoring body 1 and the vibration amplitude of the drive motor are somewhat different, the side of the temperature measuring probe closer to the drive motor experiences more severe wear. Furthermore, wear will also occur between the external connecting cable 11 and the drive motor, affecting the service life of the connecting cable 11.

[0033] On the other hand, due to the differences in wear and vibration amplitude, the monitoring probe 12 is prone to detachment or loosening from the drive motor, resulting in poor contact, which in turn affects the accuracy of the temperature measurement data. Furthermore, it may also cause signal transmission interruption, affecting the continuity of temperature measurement. The aging and wear of the connecting wire 11 will also affect the transmission of temperature measurement data and the accuracy of its detection results.

[0034] It should be noted that the temperature data measured by the monitoring probe 12 is transmitted to the temperature monitoring body 1 for processing via the connecting line 11. When the temperature exceeds the limit, the temperature monitoring body 1 can trigger an alarm. Furthermore, the specific structure of the temperature monitoring body 1, as well as the connection structure and monitoring principle of the connecting line 11 and the monitoring probe 12, are all existing technologies and will not be described in detail here.

[0035] Please refer to the following: Figures 1 to 4The following describes the drive motor temperature monitoring device and vehicle provided in this application. First, this application provides a drive motor temperature monitoring device comprising a temperature monitoring body 1, a protective box 2, and a clamping assembly 4. The bottom of the temperature monitoring body 1 is fixed to the drive motor, and the top is provided with a connecting wire 11, the end of which is provided with a monitoring probe 12. The protective box 2 is fixed to the temperature monitoring body 1 and faces the temperature measuring side of the drive motor. The upper side of the protective box 2 is provided with a wire clamping hole 23. The clamping assembly 4 is disposed inside the protective box 2. The clamping assembly 4 has a clamping hole 43 that extends vertically through the protective box 2. The side of the clamping hole 43 facing the drive motor has a notch that extends to the inner wall of the protective box 2. The connecting wire 11 passes downward through the wire clamping hole 23 so that the monitoring probe 12 extends into the protective box 2 and is clamped within the clamping hole 43.

[0036] Specifically, the protective box 2 provided in this application is a box structure with one side open, and the open side of the protective box 2 covers the temperature monitoring body 1, so that a closed temperature measuring cavity is formed between the protective box 2 and the temperature monitoring body 1, so as to enclose the monitoring probe 12 in the temperature measuring cavity. A receiving cavity 22 is formed between the protective box 2 and the temperature monitoring body 1, and the clamping assembly 4 is disposed in the receiving cavity 22.

[0037] Furthermore, the protective box 2 has a protective door 21 structure on the side opposite to the temperature monitoring body 1. One side of the protective door 21 is hinged to the side wall of the protective box 2. The protective door 21 can be opened and closed by rotating it around its hinge side. Furthermore, by opening the protective door 21, the clamping position and height of the monitoring probe 12 can be easily adjusted.

[0038] It should be understood that the protective door 21 is made of heat-transfer material, which can transfer the temperature measured by the drive motor to the monitoring probe 12. In addition, although the aforementioned protective door 21 is provided between the monitoring probe 12 and the temperature measuring point of the drive motor, the influence of the protective door 21 on temperature transfer is small and can be ignored; that is, it can be reasonably assumed that the temperature is the same between the monitoring probe 12, the protective door 21 and the temperature measuring point of the drive motor.

[0039] In addition, in this application, a notch is provided on the side of the clamp hole 43 facing the drive motor, which extends to the inner wall of the protective box 2. Therefore, the monitoring probe 12 can monitor the temperature of the protective door 21 through the notch, and thus know the temperature of the temperature measuring side of the drive motor that is in contact with the protective door 21.

[0040] Furthermore, a set of anti-slip pads 14 are provided on the left and right sides of the temperature monitoring body 1 along the first direction to prevent the device from sliding.

[0041] It should be understood that since the protective door 21 of the protective box 2 is attached to the temperature measuring side of the drive motor, when the wire clamping hole 23 is set on the top of the protective box 2, if the connecting wire 11 is passed through the corresponding wire clamping hole 23, the connecting wire 11 will not directly contact the temperature measuring side of the drive motor. Therefore, the risk of wear on the connecting wire 11 can be reduced, which helps to extend the service life of the connecting wire 11 and ensure the continuity of data transmission.

[0042] It should be noted that the protective box 2 provided in this application is fixed to the temperature monitoring body 1. Therefore, when the temperature monitoring body 1 vibrates, the vibration between the protective box 2 and the temperature monitoring body 1 is also at the same frequency and the amplitude is similar or basically the same.

[0043] It should be understood that the drive motor temperature monitoring device provided in this application can be used to realize real-time monitoring of the temperature of the drive motor; optionally, the drive motor can be replaced with other substrates that need to be monitored for temperature, in which case the temperature monitoring body 1 is directly fixed on the corresponding substrate.

[0044] Compared with the prior art, the solution shown in this application embodiment is provided with a wire clamping hole 23 and a clamping head hole 43. The wire clamping hole 23 is used to clamp the connecting wire 11 to realize the limiting of the connecting wire 11, and the clamping head hole 43 is used to clamp the monitoring probe 12 to realize the clamping of the monitoring probe 12. Thus, the monitoring probe 12 can be limited and clamped in two stages through the wire clamping hole 23 and the clamping head hole 43, thereby reducing the risk of the connecting wire 11 and the monitoring probe 12 loosening or falling off due to the vibration of the drive motor during use; Furthermore, this application also includes a protective box 2. By placing the protective box 2 on the side of the temperature monitoring body 1 facing the drive motor, the monitoring probe 12 can be placed inside the protective box 2, avoiding wear caused by direct contact between the monitoring probe 12 and the drive motor body. Specifically, in this application, the protective box 2 is attached to the temperature measuring side of the drive motor, and the clamp hole 43 has a notch that extends to the inner wall of the protective box 2. The monitoring probe 12 can monitor the temperature of the protective box 2 through this notch to indirectly obtain the real-time temperature of the drive motor. Moreover, since the monitoring probe 12 is placed inside the protective box 2, when the protective box 2 vibrates with the drive motor, the relative wear between the protective box 2 and the temperature measuring side of the drive motor replaces the wear between the monitoring probe 12 and the temperature measuring side of the drive motor in the traditional method. Since the monitoring probe 12 is clamped in the protective box 2 through the clamp hole 43, the relative wear between the monitoring probe 12 and the protective box 2 is relatively small compared to the wear between the monitoring probe 12 and the temperature measuring side of the drive motor. Therefore, the setting of the protective box 2 can effectively reduce the impact of drive motor vibration.

[0045] On the other hand, the protective box 2 and the wire clamping hole 23 also prevent direct contact wear between the connecting wire 11 and the drive motor, which can effectively reduce the risk of data distortion caused by wear of the connecting wire 11.

[0046] Therefore, the drive motor temperature monitoring device provided in this application embodiment can effectively clamp and limit the connecting wire 11 and the monitoring probe 12, and can effectively reduce the loosening and wear of the monitoring probe 12 under the high-frequency vibration of the drive motor, thereby improving the accuracy and continuity of temperature monitoring data.

[0047] Please see Figure 2 In one possible implementation, there are two connecting lines 11, each corresponding to a monitoring probe 12; the clamping assembly 4 includes a fixed block 41 and two movable blocks 42; the fixed block 41 is fixed inside the protective box 2; the two movable blocks 42 are symmetrically distributed on both sides of the fixed block 41 along a first direction and connected to the inner sidewall of the protective box 2; wherein, a clamping hole 43 is formed between each movable block 42 and the fixed block 41.

[0048] It should be noted that the temperature monitoring body 1 has two spaced connecting lines 11 on its top. The spacing direction of the two connecting lines 11 can be selectively set according to actual needs. Preferably, the two connecting lines 11 are spaced along the first direction, and each connecting line 11 corresponds to a wire clamping hole 23 and a clamping head hole 43.

[0049] Furthermore, there are two clamping holes 23 and two clamping holes 43. The two clamping holes 23 correspond one-to-one with the two connecting lines 11, and the two clamping holes 43 are arranged vertically to correspond with the two clamping holes 23. The connecting lines 11 pass downward through the corresponding clamping holes 23 so that the monitoring probe 12 extends into the protective box 2 and is clamped in the corresponding clamping hole 43.

[0050] By setting a fixed block 41 and a movable block 42 to form the aforementioned clamping hole 43, it is convenient to clamp the two monitoring probes 12; and by setting a set of fixed blocks 41 and two movable blocks 42, the two monitoring probes 12 can be clamped on both sides of the fixed block 41, which helps to improve the utilization rate of the fixed block 41 and reduce the number of parts used.

[0051] Optionally, the two movable blocks 42 are fixedly connected to the inner sidewalls of the protective box 2, and the diameter of the clamp hole 43 between the movable block 42 and the fixed block 41 remains unchanged. In this case, the monitoring probe 12 is directly inserted into the corresponding clamp hole 43 for clamping.

[0052] Optionally, the two movable blocks 42 are movably connected to the inner sidewalls of the protective box 2, and the movable blocks 42 have the freedom to move in the direction of approaching or moving away from the fixed block 41. Furthermore, when the monitoring probe 12 is inserted between the movable block 42 and the fixed block 41, the movable block 42 can press the monitoring probe 12 firmly onto the fixed block 41.

[0053] It should be understood that the fixed block 41 and the movable block 42 are clamped on the left and right sides of the monitoring probe 12 along the first direction, and the aforementioned gap is formed between the fixed block 41 and the movable block 42 to facilitate the monitoring probe 12 to monitor the temperature of the protective box 2 through the gap.

[0054] Please see Figure 2 In some embodiments, a plurality of first elastic members 44 are provided between the movable block 42 and the inner sidewall of the protective box 2, which are spaced vertically apart; wherein, when the first elastic member 44 drives the movable block 42 to press against the monitoring probe 12, the first elastic member 44 is in a compressed state.

[0055] By setting the first elastic element 44, the movable block 42 can move in the direction of approaching or moving away from the fixed block 41, thereby clamping and releasing the monitoring probe 12, and thus buffering the vibration of the monitoring probe 12.

[0056] Since the first elastic element 44 has a degree of freedom of extension and contraction along the first direction, when the drive motor drives the temperature monitoring body 1 to vibrate, the first elastic element 44 can buffer the vibration of the monitoring probe 12. The first elastic element 44 can buffer and absorb energy to reduce the vibration transmitted to the monitoring probe 12 and the connecting line 11, thereby reducing the loosening and wear of the monitoring probe 12.

[0057] It should be understood that the first elastic element 44 has a degree of freedom to extend and retract along a first direction; wherein, in the first direction, the movable block 42 presses the corresponding monitoring probe 12 against the corresponding side of the fixed block 41. Specifically, when installing the monitoring probe 12, the first elastic element 44 can be compressed first, so that the movable block 42 is moved away from the fixed block 41, thereby facilitating the insertion of the monitoring probe 12 into the clamp hole 43 formed between the movable block 42 and the fixed block 41. Then, the movable block 42 is relaxed, so that the first elastic element 44 is relaxed, and the movable block 42 presses the monitoring probe 12 against the fixed block 41. At this time, the first elastic element 44 is still in a compressed state.

[0058] Preferably, the first elastic element 44 is a spring structure. Optionally, the number of the first elastic elements 44 can be selectively set according to actual needs; preferably, there are two first elastic elements 44, which are arranged vertically at intervals.

[0059] Please see Figure 2For example, the fixed block 41 has a first arc surface on both sides along the first direction, and the movable block 42 has a second arc surface on the side facing the fixed block 41, and both the first arc surface and the second arc surface are adapted to the outer peripheral wall of the monitoring probe 12.

[0060] By setting the first arc surface and the second arc surface, the fixed block 41 and the movable block 42 are adapted to the outer peripheral wall of the monitoring probe 12, thereby ensuring the clamping effect of the fixed block 41 and the movable block 42.

[0061] Since a set of monitoring probes 12 are clamped on both sides of the fixing block 41 along the first direction, both sides of the fixing block 41 need to be set as the first arc surface.

[0062] Since the outer peripheral wall of the monitoring probe 12 is an arc-shaped surface, when the fixed block 41 and the movable block 42 are respectively provided with the first arc surface and the second arc surface, the fixed block 41 and the movable block 42 can effectively clamp the monitoring probe 12.

[0063] Please see Figure 2 or Figure 3 In one possible implementation, a limiting plate 5 is provided above the protective box 2. A limiting hole 51 that runs vertically through the limiting plate 5 and the side wall of the temperature monitoring body 1 is provided. A connecting line 11 is correspondingly limited in the limiting hole 51.

[0064] Specifically, there are two sets of limiting plates 5, which are spaced apart along the first direction. Each limiting plate 5 surrounds a limiting hole 51. The two limiting holes 51 are arranged vertically and vertically with the two clamping holes 23. A connecting line 11 is correspondingly limited in each limiting hole 51.

[0065] By setting the limiting plate 5, the position of the connecting line 11 is further limited, the limiting effect of the connecting line 11 is improved, the impact of the drive motor vibration on the connecting line 11 is reduced, and the connection stability of the monitoring probe 12 is ensured.

[0066] The limiting plate 5 is placed above the protective box 2 to further limit the connecting line 11 above, so as to avoid wear caused by direct contact between the connecting line 11 and the drive motor.

[0067] It should be understood that the limiting hole 51 and the clamping hole 23 on the limiting plate 5 are corresponding vertically to limit the upper and lower ends of the connecting wire 11 respectively, thereby increasing the clamping degree of the connecting wire 11 and reducing the risk of the connecting wire 11 falling off and wearing out.

[0068] Optionally, there may be multiple limiting plates 5 in each group, with the multiple limiting plates 5 arranged vertically at intervals, and each limiting plate 5 corresponding to a set of limiting holes 51. Specifically, the number of limiting plates 5 can be selectively set according to actual needs.

[0069] Please see Figure 2 or Figure 3 In some embodiments, the limiting plate 5 is an arc-shaped plate, and the arc-shaped plate forms a limiting hole 51 on the inner side facing the temperature monitoring body 1; one end of the limiting plate 5 is hinged to the temperature monitoring body 1, and the other end is snapped onto the temperature monitoring body 1.

[0070] By setting the limiting plate 5 as an arc-shaped plate, the inner side of the arc-shaped plate is made to fit against the outer peripheral wall of the connecting line 11; by making the limiting plate 5 hinged to the temperature monitoring body 1, the limiting plate 5 can be snapped and opened, making it convenient to snap the connecting line 11 into the corresponding limiting hole 51, or to take it out from the limiting hole 51.

[0071] Specifically, the temperature monitoring body 1 is provided with two sets of hinge shafts, and the hinge shafts extend in the vertical direction. Each limiting plate 5 is hinged to one set of hinge shafts; the limiting plate 5 can rotate around its hinge shaft.

[0072] Furthermore, two sets of limiting grooves are provided on the temperature monitoring body 1, and the limiting grooves are also extended in the vertical direction and correspond one-to-one with the hinge shaft; the limiting plate 5 can rotate around its hinge shaft and be engaged in the corresponding limiting groove.

[0073] When it is necessary to adjust the length of the connecting wire 11 extending into the protective box 2, the limiting plate 5 can be opened so that one side of the limiting plate 5 is away from the limiting groove and rotated around its hinge axis so that the connecting wire 11 can move up and down; after the connecting wire 11 is adjusted into place, the limiting plate 5 can be rotated in the opposite direction and locked into the corresponding limiting groove to fix the connecting wire 11.

[0074] Please see Figure 1 and Figure 4 In one possible implementation, the drive motor temperature monitoring device further includes a fixing plate 13 and a base 7; the fixing plate 13 is fixed to the bottom of the temperature monitoring body 1; the base 7 is fixed to the drive motor; the base 7 is provided with two oppositely arranged clamping parts 71, and a clamping space for clamping the fixing plate 13 is formed between the two clamping parts 71.

[0075] By setting a fixing plate 13, the temperature monitoring body 1 is connected to the drive motor in conjunction with the base 7; by setting two opposite clamping parts 71, they are clamped on both sides of the fixing plate 13, thereby achieving effective clamping of the fixing plate 13 and the temperature monitoring body 1.

[0076] Optionally, the two clamping parts 71 are fixed on the base 7, and the temperature monitoring body 1 is correspondingly inserted between the two clamping parts 71.

[0077] Optionally, the clamping ends of the two sets of clamping parts 71 can be close to or far from each other to clamp the fixing plate 13 at the bottom of the temperature monitoring body 1.

[0078] Specifically, the two sets of clamping parts 71 are arranged opposite each other and spaced apart along the first direction; alternatively, the two clamping parts 71 are arranged opposite each other and spaced apart along a direction perpendicular to the first direction.

[0079] Please see Figure 4 In some embodiments, the clamping part 71 includes a connecting plate 711 and a clamping plate 712; the connecting plate 711 is fixed to the top of the base 7 and extends upward; the clamping plate 712 is slidably connected to the top of the base 7 in a direction close to or away from the connecting plate 711; the clamping plate 712 is arranged parallel to the connecting plate 711 and is located on the inner side of the connecting plate 711 facing the fixing plate 13; wherein, the clamping plate 712 is used to move away from the connecting plate 711 so that the clamping plate 712 is clamped on the fixing plate 13.

[0080] By setting up a clamping plate 712 and a connecting plate 711, the clamping plate 712 can move closer to or further away from the connecting plate 711. After the clamping plate 712 moves away from the connecting plate 711, the clamping plate 712 clamps the fixing plate 13, thereby achieving the limiting and tightening of the temperature monitoring body 1.

[0081] The clamping plate 712 forms the clamping end of the clamping part 71, and the connecting plate 711 forms the fixing end of the clamping part 71. When the two clamping plates are close to each other, the fixing plate 13 can be clamped between the two clamping plates. Conversely, when the two clamping plates are far apart from each other, the two sides of the fixing plate 13 can be loosened.

[0082] Optionally, a telescopic drive is provided between the clamping plate 712 and the connecting plate 711, the telescopic drive being used to clamp the clamping plate 13 when extended.

[0083] Please see Figure 4 For example, a plurality of second elastic members 713 are provided between the connecting plate 711 and the clamping plate 712, wherein the second elastic members 713 are in a compressed state when the clamping plate 712 is pressed against the fixed plate 13 by the second elastic members 713.

[0084] By setting a second elastic member 713, the clamping plate 712 can be moved, thereby forming an elastic buffer structure between the clamping plate 712 and the connecting plate 711. When the second elastic member 713 is in a compressed state, the fixed plate 13 can be effectively clamped.

[0085] Furthermore, when the drive motor vibrates, the second elastic element 713 can effectively buffer the clamping plate 712 and the connecting plate 711. The second elastic element 713 can absorb energy and reduce the vibration transmitted to the monitoring probe 12 and the connecting line 11, thereby reducing the impact of the drive motor vibration on the temperature monitoring body 1.

[0086] Specifically, the second elastic element 713 is a spring structure. Optionally, the number of the second elastic elements 713 can be selectively set according to actual needs; preferably, there are two second elastic elements 713, which are arranged vertically at intervals.

[0087] The second elastic element 713 is used to move the clamping plate 712 toward or away from the connecting plate 711. Specifically, when installing the temperature monitoring body 1, the second elastic element 713 can be compressed first, so that the clamping plate is close to the connecting plate 711 and the two clamping plates are far apart from each other, thereby facilitating the insertion of the temperature monitoring body 1 into the clamping space formed between the two clamping plates. Then, the clamping plates are released, so that the second elastic element 713 is released, and the two sets of clamping plates clamp the temperature monitoring body 1. At this time, the second elastic element 713 is still in a compressed state.

[0088] Preferably, the clamping plate 712 has a U-shaped structure, and the opening of the U-shaped structure faces the fixing plate 13 of the temperature monitoring body 1; optionally, the two sides of the U-shaped opening of the clamping plate 712 are clamped to the two sides of the fixing plate 13; specifically, the distance between the two sides of the U-shaped structure of the clamping plate 712 is equal to or slightly less than the width of the fixing plate 13, so that the clamping plate 712 clamps the fixing plate 13.

[0089] Optionally, both the clamping plate 712 and the fixing plate 711 are detachably connected to the base, which facilitates the replacement or maintenance of the monitoring device body. The connecting wire 11 enters the protective box 2 through the clamping hole to avoid wear on the connecting wire 11 and extend its service life.

[0090] It should be noted that the present invention uses the second elastic element 713 to buffer the clamping plate 712 and the connecting plate 711, and uses the first elastic element 44 to buffer the fixed block 41 and the movable block 42, forming a two-stage elastic buffer structure from the drive motor to the monitoring probe 12. This structure can effectively absorb the high-frequency vibration of the drive motor during operation, reduce the risk of displacement or damage to the temperature monitoring body 1 due to mechanical impact, and ensure the continuity of temperature monitoring.

[0091] This application also provides a vehicle including the aforementioned drive motor temperature monitoring device.

[0092] The vehicle provided in this application, by employing the aforementioned drive motor temperature monitoring device, possesses all the beneficial effects of the aforementioned drive motor temperature monitoring device. Under the high-frequency vibration of the drive motor, it can effectively reduce the loosening of the monitoring probe 12 and the wear of the connecting wire 11, thereby improving the accuracy and continuity of temperature monitoring data.

[0093] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
