[0002] During vehicle production, fasteners are needed to lock components in place. For example, vehicle power is transmitted from the engine to the wheels via the drive shaft. After the drive shaft is connected to the brake hub, fasteners are installed to prevent the drive shaft from coming off the hub. When the vehicle moves forward or backward, the fasteners may loosen and rotate. To alleviate the insufficient locking force caused by the rotation of the fasteners, the fasteners are recessed into the grooves of the drive shaft, thereby hindering the rotation of the fasteners.

[0003] Currently, the fasteners are mainly dented by manually striking them with tools such as hammers, which is inefficient and poses a high risk of injury to operators. Utility Model Content

[0034] Currently, the fasteners are mainly dented by manually striking them with tools such as hammers, which is inefficient and poses a high risk of injury to operators.

[0035] To address the aforementioned problems, this application provides a fastener locking system, please refer to... Figures 1-2 , Figure 1 This is a first structural schematic diagram of a fastener locking system according to one or more embodiments of this application; Figure 2 This is a second structural schematic diagram of a fastener locking system according to one or more embodiments of this application.

[0036] This application provides a fastener locking system 1, which includes a device to be locked 2 and a fastener locking device 3. The device to be locked 2 includes a support post 100 and a fastener 200. The fastener 200 is sleeved on the support post 100, and the support post 100 has a groove 110 recessed relative to the fastener 200. The device to be locked 2 may include, but is not limited to, a vehicle drive shaft assembly, etc., wherein the support post 100 may include, but is not limited to, a vehicle drive shaft, bolt, stud, etc., and the fastener 200 may include, but is not limited to, a nut, etc. The fastener locking device 3 can impact the fastener 200, thereby deforming at least a portion of the fastener 200 to the inside of the groove 110, thereby preventing the fastener 200 from rotating relative to the support post 100, and locking the fastener 200 to the support post 100.

[0037] Please refer to Figures 1-6 , Figure 3 This is a first structural schematic diagram of a fastener locking device according to one or more embodiments of this application; Figure 4This is a second structural schematic diagram of a fastener locking device according to one or more embodiments of this application; Figure 5 It is based on Figure 4 A cross-sectional view of the fastener locking device shown along the AA direction; Figure 6 This is a schematic diagram of the structure of a locking device according to one or more embodiments of this application.

[0038] To address the aforementioned problems, this application provides a fastener locking device 3. The fastener locking device 3 is applied to a device 2 to be locked. The device 2 includes a support column 100 and a fastener 200. The fastener 200 is sleeved on the support column 100. The support column 100 has a groove 110 that is recessed relative to the fastener 200. The fastener locking device 3 includes a housing 10, an impact part 20, and a drive assembly 30. The housing 10 forms an accommodating space 11 and has an opening 12 that connects the accommodating space 11 to the outside. The opening 12 is used to sleeve the outer periphery of the fastener 200. The impact part 20 is disposed within the accommodating space 11 and is correspondingly disposed with respect to the groove 110. The drive assembly 30 is connected to the impact part 20 and is used to drive the impact part 20 to impact the fastener 200, so that at least a portion of the fastener 200 deforms toward the inside of the groove 110.

[0039] The housing 10 provides protection and support for the impact part 20. The housing 10 can be of any shape; for example, it can be cylindrical, with the opening 12 located at one end. The housing 10 can be fitted onto the outer periphery of the fastener 200 through the opening 12. It is understood that the opening 12 facilitates improved fit stability between the housing 10 and the device 2 to be locked. The impact part 20 is correspondingly disposed with the groove 110. It should be noted that this means the orthographic projection of the impact part 20 on the support column 100 at least partially coincides with the groove 110. The drive assembly 30 may include, but is not limited to, pneumatic and electric drive components. For example, the drive assembly 30 may include cylinders and drive motors. The drive assembly 30 can drive the impact part 20 to impact the fastener 200. Since the impact part 20 is correspondingly disposed with the groove 110, the impact part 20 can collide with the portion of the fastener 200 corresponding to the groove 110, thereby compressing the fastener 200 and causing it to deform toward the inside of the groove 110. To further illustrate, taking the fastener 200 as a nut as an example, after the nut is impacted by the impact part 20, it deforms towards the inside of the groove 110, thereby causing the deformed part of the nut to be stuck in the groove 110, thus preventing the nut from rotating relative to the support column 100 and achieving the locking of the nut.

[0040] Through the above embodiments, the housing 10 can be sleeved on the outer periphery of the fastener 200 through the opening 12, which improves the cooperation stability between the fastener locking device 3 and the device to be locked 2. The driving component 30 drives the impact part 20 to impact the fastener 200, thereby causing at least a part of the fastener 200 to deform into the groove 110 on the support column 100, thereby causing the fastener 200 to be partially locked in the groove 110, preventing the fastener 200 from rotating. Thus, the structure is simple, improves the automation of locking the fastener 200, and improves the locking efficiency. At the same time, the impact part 20 is located in the accommodating space 11, reducing the risk of injury to the operator.

[0041] In some embodiments, the impact portion 20 includes a main body portion 21 and a protrusion portion 22. The main body portion 21 is located within the accommodating space 11, and the protrusion portion 22 is disposed on the side of the main body portion 21 facing the opening 12. The protrusion portion 22 is correspondingly disposed with respect to the groove 110. The driving assembly 30 is used to drive the main body portion 21 to drive the protrusion portion 22 to impact the fastener 200. It is understood that the protrusion portion 22 protrudes from the main body portion 21, and the main body portion 21 can provide support and fixation for the protrusion portion 22, thereby making the impact process of the protrusion portion 22 more stable. At the same time, it is easier for the protrusion portion 22 to more accurately cooperate with the groove 110, thereby improving the accuracy of the protrusion portion 22 impacting the fastener 200. Furthermore, the radial dimension of the protrusion portion 22 can be less than or equal to the radial dimension of the groove 110, thereby improving the impact effect and facilitating the deformation of the fastener 200 towards the inside of the groove 110.

[0042] In some embodiments, the fastener locking device 3 includes a positioning part 40, which is connected to the inner wall of the housing 10 and located on the side of the main body 21 facing the opening 12. When the housing 10 is fitted with the fastener 200, at least a portion of the positioning part 40 is located in the groove 110 so that the protrusion 22 is correspondingly disposed with the groove 110. The positioning part 40 may include, but is not limited to, a pin. Understandably, during the process of the operator fitting the fastener locking device 3 onto the fastener 200, it is necessary to adjust the posture of the fastener locking device 3 so that the protrusion 22 corresponds to the groove 110. By setting the positioning part 40, the operator can more quickly position the fastener locking device 3 accurately, thereby improving efficiency. For example, when the protrusion 22 does not correspond to the groove 110, the positioning part 40 cannot enter the groove 110. The operator can rotate the housing 10 around the axis so that the positioning part 40 corresponds to the groove 110 and enters the groove 110, thereby making the positioning part 40 and the groove 110 cooperate to prevent the housing 10 from rotating, so that the operator knows that the positioning is complete. At this time, the protrusion 22 and the groove 110 are properly aligned. In some application scenarios, the positioning part 40 can also be used to limit the movable space of the main body 21 within the accommodating space 11, reducing the risk of the main body 21 exiting the accommodating space 11 from the opening 12.

[0043] In some embodiments, there are two positioning portions 40, which are spaced apart circumferentially on the support column 100. The orthographic projection of the protrusion 22 in the groove 110 lies between the orthographic projections of the two positioning portions 40 in the groove 110. It is understood that the two positioning portions 40 can further restrict the movement space of the housing 10 in the circumferential direction of the support column 10 after the protrusion 22 corresponds to the groove 110, thereby improving positioning stability and accuracy. Furthermore, the orthographic projection of the protrusion 22 in the groove 110 lies between the orthographic projections of the two positioning portions 40 in the groove 110, facilitating the avoidance of the protrusion 22 by the gap between the two positioning portions 40, thus mitigating the risk of interference between the protrusion 22 and the positioning portions 40 during impact.

[0044] In some embodiments, the drive assembly 30 drives the impact portion 20 to move between a first position p1 and a second position p2. At the first position p1, the protrusion 22 is spaced apart from the fastener 200, and at the second position p2, the protrusion 22 abuts against the fastener 200. It is understood that during the impact of the impact portion 20 on the fastener 200, the drive assembly 30 can drive the impact portion 20 from the first position p1 to the second position p2, thereby impacting the fastener 200 and causing it to deform. After the impact portion 20 completes its impact, the drive assembly 30 can also drive the impact portion 20 from the second position p2 back to the first position p1, thus resetting and preparing for the next impact. Therefore, the drive assembly 30 enables the impact portion 20 to reciprocate between the first position p1 and the second position p2, facilitating automated resetting of the impact portion 20, enabling multiple impacts, improving the automation level of the fastener locking device 3, and increasing impact efficiency.

[0045] In some embodiments, the impact part 20 cooperates with the housing 10 to form an air cavity 13 on the side of the impact part 20 away from the outlet 12. The bottom wall of the housing 10 is provided with an air inlet 14. The drive assembly 30 includes an air pipe 31, which communicates with the air cavity 13 through the air inlet 14. Exemplarily, the housing 10 can be a cylindrical housing, and the shape of the impact part 20 can be circular. The impact part 20 can cooperate with the bottom wall and part of the side wall of the housing 10 to form the air cavity 13. It is understood that the drive assembly 30 can control the air pressure in the air cavity 13 through the air pipe 31 and the air inlet 14. Exemplarily, when it is necessary to drive the impact part 20 to impact, the drive assembly 30 can pump air into the air cavity 13, thereby pushing the impact part 20 to impact the fastener 200. When it is necessary to reset the impact part 20, the drive assembly 30 can extract air from the air cavity 13, thereby causing the impact part 20 to return to the first position p1.

[0046] In some embodiments, the protrusion 22 has an impact surface 221. At the second position p2, the protrusion 22 contacts the fastener 200 through the impact surface 221, and the impact surface 221 is arranged parallel to the bottom wall surface 111 of the groove 110. It is understood that the protrusion 22 contacts and collides with the fastener 200 through the impact surface 221. By arranging the impact surface 221 parallel to the bottom wall surface 111 of the groove 110, it is easier to make the deformation of the fastener 200 after impact match the shape of the groove 110, thereby mitigating the risk of structural failure caused by surface cracking of the fastener 200 due to impact.

[0047] In some embodiments, the impact surface 221 is inclined relative to the direction of the interval between the first position p1 and the second position p2. It should be noted that the impact surface 221 is inclined relative to the direction of the interval between the first position p1 and the second position p2, that is, the impact surface 221 is inclined relative to the impact direction of the impact portion 20. Compared with the impact surface 221 being parallel or perpendicular to the impact direction, it can better compress the fastener 200 along the inner side of the groove 110, so that the fastener 200 deforms toward the inner side of the groove 110, thereby improving the reliability of the fastener locking device 3.

[0048] Combination Figure 7 , Figure 7 This is a third structural schematic diagram of a fastener locking device according to one or more embodiments of this application.

[0049] In some embodiments, the drive assembly 30 includes a drive shaft 32, and the bottom wall of the housing 10 is provided with a clearance opening 15. The drive shaft 32 is connected to the impact part 20 through the clearance opening 15. Exemplarily, the drive shaft 32 can move along the axial direction of the support column 100, thereby driving the impact part 20 to move at a first position p1 and a second position p2. The structure of moving the impact part 20 by the drive shaft 32 is simple and the cost is low. Specifically, the drive shaft 32 can be connected to a drive component, which may include, but is not limited to, an electric motor or a cylinder, so that the drive component drives the drive shaft 32 and extends into the receiving space 11 through the clearance opening 15 to drive the impact part 20 to move.

[0050] In summary, this application provides a fastener locking device 3, which is applied to a device 2 to be locked. The device 2 includes a support column 100 and a fastener 200. The fastener 200 is sleeved on the support column 100. The support column 100 has a groove 110 that is recessed relative to the fastener 200. The fastener locking device 3 includes a housing 10, an impact part 20, and a drive assembly 30. The housing 10 forms an accommodating space 11 and has an opening 12 that connects the accommodating space 11 to the outside. The opening 12 is used to sleeve the outer periphery of the fastener 200. The impact part 20 is disposed in the accommodating space 11 and is correspondingly disposed with the groove 110. The drive assembly 30 is connected to the impact part 20 and is used to drive the impact part 20 to impact the fastener 200, so that at least a portion of the fastener 200 deforms toward the inside of the groove 110. Through the above embodiments, the housing 10 can be sleeved on the outer periphery of the fastener 200 through the opening 12, which improves the cooperation stability between the fastener locking device 3 and the device to be locked 2. The driving component 30 drives the impact part 20 to impact the fastener 200, thereby causing at least a part of the fastener 200 to deform into the groove 110 on the support column 100, thereby causing the fastener 200 to be partially locked in the groove 110, preventing the fastener 200 from rotating. Thus, the structure is simple, improves the automation of locking the fastener 200, and improves the locking efficiency. At the same time, the impact part 20 is located in the accommodating space 11, reducing the risk of injury to the operator.
