[0031] Aspects and exemplary embodiments of the present application will be described in detail below. To make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only provided to provide a better understanding of the present application by showing examples of the present application.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article, or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0033] In today's society, people have higher and higher requirements for the use of various parts or devices. After some parts or devices are manufactured, certain simulation tests need to be carried out to detect whether the parts or devices meet the requirements of actual use. During the detection process, the parts or devices to be detected need to be fixed on the test bench. The process of corresponding fixing different types of parts and devices by the test personnel to the test bench is relatively complicated.

[0034] Taking the test of a motor as an example, the fixing positions of motors of different models are different, the test items for motors are also different, and the corresponding test benches are also different. When the test personnel want to fix the motor on the test bench, they need to correspond to different motors and test benches, and the fixing is relatively complicated.

[0035] In view of this, please refer to Figures 1 to 3An embodiment of the present application provides a fixing fixture for fixing a test piece to a test bench. The fixing fixture includes a first fixing assembly 10 and a second fixing assembly 20 that are detachably connected in a first direction X. The second fixing assembly 20 has a first end face D1 on a second square. The first fixing assembly 10 has a second end face D2 at one end in the first direction X that faces away from the second fixing assembly 20. The first direction X intersects with the second direction Y. The test piece is configured to be connected to the second fixing assembly 20 and located on the side where the first end face D1 is located. The test bench is configured to be connected to the first fixing assembly 10 and located on the side where the second end face D2 is located.

[0036] The fixed fixture provided in this application is used to fix the test piece to be tested on the test bench to facilitate the test personnel to test the test piece. Among them, the test piece is a device that needs to be simulated tested after the production is completed and before actual application. For example, the test piece can be an engine, a motor or a steering system and other parts and equipment. The test bench is a support bench when testing the test piece. For example, the test bench can be an engine test bench, a motor test bench, a steering performance test bench, etc. For the convenience of description, in this application, the test piece is described as an electric motor, and the test bench is described as an electric motor test bench.

[0037] The fixture includes a first fixing assembly 10 and a second fixing assembly 20 that are detachably connected in a first direction X. The motor is connected to the second fixing assembly 20, and the test bench is connected to the first fixing assembly 10. The first fixing assembly 10 and the second fixing assembly 20 are two relatively independent fixing structures, and the first fixing assembly 10 and the second fixing assembly 20 are detachably connected. That is, when the first fixing assembly 10 and the second fixing assembly 20 are in a connected state, they can achieve the connection between the motor and the test bench. When the first fixing assembly 10 and the second fixing assembly 20 are in a disassembled state, they can achieve the disassembly between the motor and the test bench.

[0038] The first fixing assembly 10 and the second fixing assembly 20 extend and are connected along a first direction X. The first fixing assembly 10 has a second end surface D2 at its end facing away from the second fixing assembly 20 in the first direction X, and the second fixing assembly 20 has a first end surface D1 in the second direction Y. The first direction X and the second direction Y intersect. The motor is located on the side of the first end surface D1 of the second fixing assembly 20, and the test bench is located on the side of the second end surface D2 of the first fixing assembly 10. The motor and the second fixing assembly 20 are connected along the second direction Y, and the second fixing assembly 20, the first fixing assembly 10, and the test bench are connected in sequence along the first direction X. By adopting the above-mentioned connection method, on the one hand, the test personnel can avoid interference between the first fixing component 10 and the test bench when installing and disassembling the motor and the second fixing component 20 along the second direction Y, and avoid interference with the motor when installing and disassembling the first fixing component 10, the second fixing component 20 and the test bench along the first direction X; on the other hand, the fixing tool as a whole is on one side relative to the motor in the second direction Y. When the structure on the side of the motor facing away from the fixing tool along the second direction Y generates a certain force on the motor, the fixing tool can stably support and fix the motor.

[0039] The overall external structure of the fixing tool, that is, the shape of the first fixing component 10 and the second fixing component 20, is not restricted in the embodiment of the present application, and is specifically designed in combination with the actual use scenario of the fixing tool. For example, the first fixing component 10 and the second fixing component 20 are both rectangular block structures, and the two are interconnected to form a long strip structure, the first direction X is its length direction, and the second direction Y is its width direction. For example, the first fixing component 10 and the second fixing component 20 are both rectangular block structures, and the two are interconnected to form an L-shaped structure, the first direction X is the length direction of the first fixing component 10, and the second direction Y is the length direction of the second fixing component 20. In the present application, the first direction X is preferably a vertical direction, and the second direction Y is preferably a direction in the horizontal plane.

[0040] In summary, in the embodiment of the present application, the fixing fixture includes a detachably connected first fixing component 10 and a second fixing component 20, which can facilitate the connection and fixation between the motor and the test bench by the test personnel; at the same time, even for different models of motors, only different second fixing components 20 need to be set to correspond thereto, without having to consider the problem of different connection positions between different models of motors and the test bench, thereby reducing the difficulty of connecting the motor and the test bench. The connection method in the embodiment of the present application can, on the one hand, enable the test personnel to avoid interference between the first fixing component 10 and the test bench when installing and disassembling the motor and the second fixing component 20 along the second direction Y, and avoid interference with the motor when installing and disassembling the first fixing component 10, the second fixing component 20 and the test bench along the first direction X; on the other hand, the fixing fixture as a whole is on the side of the motor in the second direction Y. When the structure on the side of the motor facing away from the fixing fixture along the second direction Y exerts a certain force on the motor, the fixing fixture can stably support and fix the motor.

[0041] In some embodiments, see Figures 1 to 2 The first fixing assembly 10 includes a first connecting member 11 and a second connecting member 12 connected in a first direction X. The connection size between the first connecting member 11 and the second connecting member 12 in the first direction X is adjustable.

[0042] The first connecting member 11 and the second connecting member 12 are two structural members of the first fixing component 10. The first connecting member 11 and the second connecting member 12 are connected to each other in the first direction X. The distance between the two ends of the first fixing component 10 in the first direction X is determined by the relative positional relationship between the first connecting member 11 and the second connecting member 12. That is, the distance between the motor and the test bench in the first direction X is determined by the relative positional relationship between the first connecting member 11 and the second connecting member 12.

[0043] The connection dimensions of the first connecting member 11 and the second connecting member 12 in the first direction X are adjustable. The tester can control the distance between the two ends of the first fixing component 10 in the first direction X by adjusting the connection dimensions of the first connecting member 11 and the second connecting member 12 in the first direction X. That is, by adjusting the connection dimensions of the first connecting member 11 and the second connecting member 12 in the first direction X, the distance between the motor and the test bench in the first direction X can be adjusted to meet different requirements of the motor during the test process.

[0044] In some embodiments, see Figures 1 to 2 The first connecting member 11 is rotatably arranged relative to the second connecting member 12 around the axis L1, and the axis L1 is parallel to the first direction X and passes through the first connecting member 11.

[0045] A relative rotation can occur between the first connecting member 11 and the second connecting member 12 about an axis L1 parallel to the first direction X, which can cause the rotation of the second fixing assembly 20 and the motor, realizing the orientation adjustment of the motor in the horizontal plane, facilitating the connection between one end of the motor along the second direction Y away from the second fixing assembly 20 and other structures at different angles. The arrangement that the axis L1 passes through the first connecting member 11 enables the first connecting member 11 to stably support the second connecting member 12.

[0046] In some embodiments, refer to Figures 1 to 2 , the first connecting member 11 includes a threaded hole extending along the first direction X, and the second connecting member 12 includes an external thread threadedly connected to the threaded hole. The first connecting member 11 is arranged as a cylindrical structure. The first connecting member 11 is provided with a cylindrical threaded hole along the first direction X, and the position of the second connecting member 12 is a threaded rod, and the threaded rod can be threadedly connected to the threaded hole. By the way of threaded connection between the threaded rod and the threaded hole, when the first connecting member 11 and the second connecting member 12 rotate through threaded connection, the distance between the motor and the test bench in the first direction X and the orientation of the motor in the horizontal plane can be adjusted simultaneously.

[0047] In some embodiments, the first connecting member 11 includes a sliding portion and a rotating portion rotatably connected to the sliding portion. Among them, the sliding portion is slidably connected to the second connecting member 12 to adjust the connection dimension between the first connecting member 11 and the second connecting member 12 in the first direction X, and relative rotation can occur between the rotating portion and the sliding portion to adjust different orientations of the motor in the horizontal plane.

[0048] In some embodiments, refer to Figures 1 to 2 , the first fixing assembly 10 further includes a locking member 13 for locking the relative position between the first connecting member 11 and the second connecting member 12. A communication hole is provided on the first connecting member 11 that communicates the threaded hole with the external environment along the third direction. A part of the locking member is located in the communication hole and is in contact with or connected to the second connecting member 12. Among them, the third direction can be parallel to the second direction Y or intersect with the second direction Y. Whether the third direction is parallel or intersects with the second direction Y, both the second direction Y and the third direction intersect with the first direction X.

[0049] In one embodiment, the communication hole is arranged as a threaded hole, and the locking member 13 is arranged as a threaded rod. The threaded rod can be threadedly connected to the threaded hole. One end of the threaded rod can pass through the threaded hole and abut against the second connecting member 12, and the relative position between the first connecting member 11 and the second connecting member 12 is fixed by relying on the threaded locking force between the threaded rod and the threaded hole.

[0050] In one embodiment, the connecting hole is set as a smooth hole, the locking member 13 is set as a clamping rod, and a corresponding clamping position is set on the second connecting member 12. One end of the clamping rod can pass through the smooth hole and be clamped to the clamping position on the second connecting member 12. The relative position between the first connecting member 11 and the second connecting member 12 is fixed by relying on the clamping force between the clamping rod and the smooth hole.

[0051] In some embodiments, see Figures 1 to 2 The first fixing assembly 10 includes a first mounting member 14 connected to a side of the first connecting member 11 away from the second fixing assembly 20, a second mounting member 15 connected to a side of the second connecting member 12 facing the second fixing assembly 20, and a first reinforcement member 16. The second mounting member 15 is connected to the second fixing assembly 20. The first reinforcement member 16 is connected to a side of the first mounting member 14 facing the first connecting member 11 and is connected to the outer peripheral side of the first connecting member 11.

[0052] The first mounting member 14 is used to connect the first connecting member 11 to the test bench. The projected area of the first mounting member 14 in the first direction X is larger than the projected area of the first connecting member 11 in the first direction X, so as to facilitate connection to the test bench. The second mounting member 15 is used to connect the second connecting member 12 to the second fixing assembly 20. The projected area of the second mounting member 15 in the first direction X is larger than the projected area of the second connecting member 12 in the first direction X.

[0053] The first reinforcement member 16 is used to increase the overall support strength of the first fixing assembly 10. The first reinforcement member 16 is connected to both the first mounting member 14 and the first connecting member 11. The first connecting member 11 and the first mounting member 14 serve as the overall basic support of the fixing tool. The provision of the first reinforcement member 16 can increase the connection strength between the first connecting member 11 and the first mounting member 14, ensuring the overall basic support of the fixing tool.

[0054] Furthermore, a plurality of first reinforcement members 16 are provided, and the plurality of first reinforcement members 16 are simultaneously connected to the first mounting member 14 and the first connecting member 11 . The plurality of first reinforcement members 16 are spaced apart and arranged around the outer circumference of the first connecting member 11 .

[0055] In some embodiments, see Figure 1 、 Figure 3 and Figure 4 The second fixing assembly 20 includes a third connecting member 21 connected to the first fixing assembly 10, and a fourth connecting member 22 connected to the side of the third connecting member 21 facing away from the first fixing assembly 10. The fourth connecting member 22 includes a first end surface D1 and is used to connect to the test piece.

[0056] The third connecting member 21 and the fourth connecting member 22 are two structural members of the second fixing assembly 20. The third connecting member 21 and the fourth connecting member 22 are connected to each other in the first direction X. The third connecting member 21 is connected to the second mounting member 15. The fourth connecting member 22 includes a first end face D1, and the motor is connected to one side of the first end face D1 of the fourth connecting member 22. Wherein, the third connecting member 21 and the fourth connecting member 22 can be directly integrally formed, or can be formed separately and then connected by welding.

[0057] In some embodiments, please refer to Figure 1 、 Figure 3 and Figure 4 , along the first direction X, the size of the third connecting member 21 is larger than that of the fourth connecting member 22; along the second direction Y, the size of the fourth connecting member 22 is larger than that of the third connecting member 21. Through the above settings, on the one hand, while ensuring the connection between the third connecting member 21 and the second mounting member 15 in the first direction X, it can also ensure the connection between the fourth connecting member 22 and the motor in the second direction Y; on the other hand, the reasonable size design can reduce the material used for the third connecting member 21 and the fourth connecting member 22, and reduce the production cost.

[0058] In some embodiments, please refer to Figure 1 、 Figure 3 and Figure 4 , the fourth connecting member 22 includes a first plate 221 and a protruding portion 222 connected to the first plate 221. The first plate 221 includes a first end face D1. The protruding portion 222 protrudes relative to the first end face D1. The protruding portion 222 has a third end face D3 facing away from the first plate 221. The protruding portion 222 is used to connect the test piece to be tested, and the third end face D3 abuts against the test piece to be tested, so that a part of the structure of the test piece to be tested is located between the first end face D1 and the third end face D3.

[0059] The first plate 221 is the main body part of the fourth connecting member 22. The first plate 221 has a first end face D1 along the second direction Y. The protruding portion 222 is connected to the first plate 221 along the second direction Y. The protruding portion 222 protrudes relative to the first end face D1. The end face of the protruding portion 222 facing away from the first plate 221 is the third end face D3. The motor is connected to the first plate 221 through the protruding portion 222. When the motor is connected to the protruding portion 222, a part of the structure of the motor is located between the first end face D1 and the third end face D3. Due to the setting of the protruding portion 222, a gap is formed between the first end face D1 and the third end face D3 along the second direction Y, so that a corresponding accommodation space is provided for a part of the structure of the motor, avoiding the situation of structural interference when the motor is connected to the first plate 221, and facilitating the tester to connect the motor to the first plate 221.

[0060] In some embodiments, please refer to Figure 1 、Figure 3 and Figure 4 There are multiple protrusions 222. The multiple protrusions 222 are spaced apart from each other and jointly enclose an avoidance space for accommodating part of the structure of the workpiece to be tested. The multiple protrusions 222 are spaced apart from each other and are correspondingly connected to multiple connection positions on the motor. An avoidance space is formed by enclosing between the multiple protrusions 222, and part of the structure of the motor is inside the avoidance space. The formation of the avoidance space can not only accommodate part of the structure of the motor, but also limit the motor to a certain extent during the connection and installation process, facilitating the installation of the motor by the tester.

[0061] In some embodiments, please refer to Figure 1 、 Figure 3 and Figure 4 The second fixing assembly 20 further includes a second reinforcing member 23. The third connecting member 21 includes a second plate 211. The fourth connecting member 22 includes a first plate 221. The first plate 221 includes a first end face D1 and the first plate 221 is bent and connected to the second plate 211. The second reinforcing member 23 is fixed to the side of the first plate 221 away from the first end face D1 and is fixed to the side of the second plate 211 facing the first plate 221.

[0062] The first plate 221 serves as the main structure of the fourth connecting member 22, and the second plate 211 serves as the main structure of the third connecting member 21. The first plate 221 and the second plate 211 are bent and connected to form the main structure of the second fixing assembly 20. The motor is installed on one side of the first end face D1 of the first plate 221.

[0063] The second reinforcing member 23 is used to enhance the overall strength of the second fixing assembly 20. The second reinforcing member 23 is connected to both the first plate 221 and the second plate 211 at the same time, which can strengthen the connection strength between the first plate 221 and the second plate 211. When the motor is in the testing process, it will inevitably be affected by many external forces, thus generating corresponding forces on the first plate 221. The second reinforcing member 23 is arranged on the side of the first plate 221 away from the first end face D1, that is to say, the second reinforcing member 23 and the motor are respectively on both sides of the first plate 221 along the second direction Y. While avoiding interference with the motor, it can further fix the first plate 221, thereby ensuring the stability of the first plate 221, and further ensuring the stability of the motor during the testing process and reducing the vibration of the motor during the testing process.

[0064] In some embodiments, please refer to Figures 1 to 2, the first plate 221 is a rectangular plate or a hexagonal plate, the second plate 211 is a rectangular plate, the second plate 211 serves as a base, and the first plate 221 is welded to the second plate 211. The protrusion 222 is arranged as a cylindrical sleeve, and the setting position of the protrusion 222 is determined in combination with the connection position of the motor. The axial length of the cylindrical sleeve is such that interference between the motor and the first plate 221 is avoided. The second reinforcing member 23 is arranged as a triangular plate, and the second reinforcing member 23 is welded to both the first plate 221 and the second plate 211 simultaneously. The motor is connected to the protrusion 222 by bolts.

[0065] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 , the first fixing assembly 10 further includes a plurality of fixing members 24, and the fixing members 24 are fixedly connected to the first fixing assembly 10 and the second plate 211. The plurality of fixing members 24 are arranged on both sides of the first plate 221 along the second direction Y.

[0066] Both ends of the second plate 211 along the second direction Y protrude from the first plate 221. A plurality of fixing positions are provided on the second plate 211, and the plurality of fixing positions are arranged on both sides of the first plate 221 along the second direction Y. The fixing members 24 are connected to the fixing positions to connect the second plate 211 to the second mounting member 15. After the motor is connected to the first plate 221, the motor generates corresponding acting forces on the first plate 221, and the first plate 221 will generate corresponding acting forces on the second plate 211. Therefore, it is necessary to connect the second plate 211 to the second mounting member 15 relatively stably.

[0067] Arranging the plurality of fixing positions on both sides of the first plate 221 along the second direction Y is equivalent to arranging the positions where the second mounting member 15 applies acting forces to the second plate 211 on both sides of the first plate 221, and the connection position between the first plate 221 and the second plate 211 is the position where the first plate 221 applies acting forces to the second plate 211. The above setting realizes that the positions where the second mounting member 15 applies acting forces to the second plate 211 surround the circumferential side of the position where the first plate 221 applies acting forces to the second plate 211. No matter what acting forces the first plate 221 applies to the second plate 211, the acting forces applied by the second mounting member 15 surrounding its circumferential side to the second plate 211 can stably fix the second plate 211, so as to improve the position stability of the second fixing assembly 20 relative to the first fixing assembly 10, thereby improving the position stability of the motor during the test and reducing the vibration of the motor during the test.

[0068] The fixing member 24 can be set as a fixing bolt and a fixing nut.
