[0055] As shown in Figure 8, a first matching portion 1511 is provided on the first driving member 151, and the second driving member 152 is rotatably provided at one end of the first driving member 151. A second matching portion 1521 and a second triggering portion 1522 are provided on the second driving member 152. In the second state, after the first triggering portion 113 is matched and connected with the second triggering portion 1522, the second triggering portion 1522 rotates, and the first matching portion 1511 and the second matching portion 1521 match and drive the first driving member 151 to move upward. The first driving member 151 moves and pushes out the locking member 14. When the locking member 14 is matched and locked with the locking portion 112, the trailer hook is connected and locked with the connecting shell 11 to prevent the trailer hook from falling off. The trailer hook connection is stable, and the locking member 14 is tightly fitted with the inner wall of the locking portion 112, which can eliminate the noise and abnormal sound generated when the trailer hook is matched with the connecting shell 11.

[0056] According to one embodiment of the present invention, a limiting notch 15231 suitable for accommodating the first matching portion 1511 is formed on the second matching portion 1521 , and the limiting notch 15231 is suitable for preventing the first driving member 151 from moving in the second state.

[0057] As shown in FIG7 , in the second state, under the action of the first trigger portion 113, the second trigger portion 1522 rotates and drives the second matching portion 1521 to rotate.

[0059] As shown in Figures 10 and 11, a second matching portion 1521 is provided on the base 1523, and a limiting notch 15231 is formed on one side of the base 1523. In the first state, that is, when the trailer hook and the connecting shell 11 are disconnected, one end of the base 1523 facing the first driving member 151 abuts against the first matching portion 1511, so that the base 1523 can limit the movement of the first driving member 151, the first driving member 151 cannot move, and the locking member 14 is not locked with the locking portion 112; in the second state, the base 1523 The limiting notch 15231 on the base 1523 is aligned with the first matching portion 1511, and the movement of the first matching portion 1511 is unobstructed. The first driving member 151 moves until the first matching portion 1511 is completely accommodated in the limiting notch 15231. At this time, the locking member 14 is aligned with the locking portion 112. The movement of the first driving member 151 drives the locking member 14 to move. The first driving member 151 pushes the locking member 14 out and pushes the locking member 14 into the locking portion 112. After the locking member 14 and the locking portion 112 are locked, the assembly of the trailer hook and the connecting housing 11 is completed. The present application provides a limiting notch 15231 on the base 1523 to avoid movement of the first driving member 151 in the second state, so that the locking member 14 can be locked with the locking portion 112. The locking member 14 and the locking portion 112 are simple to cooperate with each other, and the connection between the trailer hook and the connecting housing 11 is convenient.

[0060] According to one embodiment of the present invention, the second driving member 152 further includes an extension section 1524, which is arranged at one end of the base 1523 away from the first driving member 151, and the second trigger portion 1522 is arranged at the top of the extension section 1524 to be suitable for cooperating with the first trigger portion 113.

[0061] Specifically, in the second state, the extension section 1524 cooperates with the first trigger portion 113, and the extension section 1524 stops against the first trigger portion 113. The extension section 1524 is pushed and rotated by the first trigger portion 113, and the extension section 1524 drives the base 1523 to rotate, so that the limiting notch 15231 on the base 1523 is opposite to the first matching portion 1511, and the movement of the first matching portion 1511 is not blocked, so that the first driving member 151 can move and move until the first matching portion 1511 is completely accommodated in the limiting notch 15231. At this time, the locking member 14 is opposite to the locking portion 112, and the movement of the first driving member 151 drives the locking member 14 to move. The first driving member 151 pushes the locking member 14 out of the locking port 122 and pushes the locking member 14 into the locking portion 112. After the locking member 14 cooperates and locks with the locking portion 112, the assembly of the trailer hook and the connecting shell 11 is completed.

[0062] According to one embodiment of the present invention, a first inclined surface 1131 is formed on the first trigger portion 113, and the first inclined surface 1131 is inclined in the circumferential direction; a second inclined surface 15221 is formed on the second trigger portion 1522, and the second inclined surface 15221 is suitable for abutting against the first inclined surface 1131 and rotating under the push of the first inclined surface 1131.

[0063] Specifically, the structures of the first trigger portion 113 and the second trigger portion 1522 are shown in FIG10 . A cover plate 114 is provided at one end of the connecting shell 11 . The cover plate 114 closes one end of the first locking cavity 111 . The first trigger portion 113 is fixedly connected to the cover plate 114 of the connecting shell 11 . The first trigger portion 113 extends in a direction away from the cover plate 114 . A first inclined surface 1131 inclined in a circumferential direction is formed on the first trigger portion 113 . A second inclined surface 15221 is formed on the second trigger portion 1522 . The first trigger portion 113 contacts the second trigger portion 1522 through the first inclined surface 1131 and the second inclined surface 15221 and pushes the second trigger portion 1522 to rotate. The first trigger portion 113 is fixedly arranged on the cover plate 114 and cannot rotate. The second inclined surface 15221 contacts the first inclined surface 1131 and is pushed by the first inclined surface 1131 to rotate. When the first trigger portion 113 and the second trigger portion 1522 are matched, the second trigger portion 1522 drives the second matching portion 1521 to rotate, and the first matching portion 1511 is pushed to be accommodated in the limiting notch 15231. At this time, as shown in Figure 7, the first driving member 151 moves and pushes the locking member 14 from the locking mouth 122 into the locking portion 112. The locking member 14 is limited and locked by the locking portion 112 and fits into the inner wall of the locking portion 112, thereby stably connecting the trailer hook to the connecting shell 11.

[0064] According to one embodiment of the present invention, the trailer hook has a mating section 12 which can be selectively received in the first locking cavity 111 , and a second locking cavity 121 for receiving the locking member 14 , the first driving member 151 and the second driving member 152 is formed in the mating section 12 .

[0065] Specifically, the locking member 14 can be translatedly arranged in the second locking cavity 121, and the locking member 14 can be moved out of the second locking cavity 121 and cooperate with the locking portion 112; the first driving member 151 is movably arranged in the second locking cavity 121 and can selectively drive the locking member 14 to move, and the first driving member 151 is provided with a first matching portion 1511; the second driving member 152 is rotatably arranged in the second locking cavity 121 and the second driving member 152 is arranged at one end of the first driving member 151, and the second driving member 152 is provided with a second matching portion 1521 and a second triggering portion 1522. After the matching section 12 is accommodated in the first locking cavity 111, the second triggering portion 1522 is suitable for rotating under the action of the first triggering portion 113, and the second driving member 152 rotates to the second matching portion 1521 and cooperates with the first matching portion 1511 to drive the first driving member 151 to move.

[0066] When the trailer hook is used, it is only necessary to control the first driving member 151 to move downward along the second locking cavity 121 and move the matching section 12 out of the first locking cavity 111. The movement of the first driving member 151 will cause the locking member 14 to lose support on the side away from the locking portion 112. During the manual operation of pulling the matching section 12 out of the first locking cavity 111, the matching section 12 and the connecting shell 11 move relative to each other, and the inner wall of the locking portion 112 will push the locking member 14 out and re-accommodate it in the second locking cavity 121. After the locking member 14 is disconnected from the locking portion 112, the movement of the matching section 12 in the first locking cavity 111 is unobstructed, and the trailer hook can be detached from the connecting shell 11. After the trailer hook is taken out, it can be stored in the trunk to prevent the trailer hook from being damaged by the external environment, extend the service life of the trailer hook, and ensure the aesthetics of the vehicle cross beam.

[0067] According to one embodiment of the present invention, the mating section 12 is formed with a locking mouth 122 that connects the second locking cavity 121 with the first locking cavity 111. The locking mouth 122 is suitable for corresponding to the locking portion 112 after the mating section 12 is accommodated in the first locking cavity 111. The locking member 14 can optionally protrude from the locking mouth 122 and cooperate with the locking portion 112.

[0069] According to one embodiment of the present invention, the trailer hook assembly 1 further includes a first elastic member 161 , which is disposed around the outer periphery of the extension section 1524 . The first elastic member 161 is adapted to drive the base 1523 to abut against the first matching portion 1511 in the first state.

[0070] As shown in Figures 6 to 12, a first elastic member 161 is provided on the periphery of the extension section 1524. The first elastic member 161 can be constructed as a torsion spring. In the first state, that is, the first trigger portion 113 has not yet engaged with the second trigger portion 1522, under the action of the torsion spring's own torsion in the normal state, at least part of the first engaging portion 1511 always remains in contact with the second engaging portion 1521, thereby limiting the movement of the first driving member 151. When the first trigger portion 113 engages with the second trigger portion 1522, the first trigger portion 113 engages with the second trigger portion 1522. The first inclined surface 1131 on the torsion spring 1511 abuts against the second inclined surface 15221 on the extension section 1524. The extension section 1524 rotates under the push of the first trigger portion 113. The extension section 1524 rotates and applies force to the first elastic member 161, overcoming the torsion force of the torsion spring itself and pushing the base 1523 to rotate, so that the first driving member 151 can move and accommodate the first matching portion 1511 in the limiting notch 15231. The movement of the first driving member 151 can drive the locking member 14 to move and lock with the locking portion 112. The present application sets a first elastic member 161 on the periphery of the extension section 1524, which can limit the second matching portion 1521 to always abut against the first matching portion 1511 in the first state, and in the second state, the first elastic member 161 can drive the first matching portion 1511 to rotate, so that the first driving member 151 can move and realize the locking of the trailer hook and the connecting shell 11. The second driving member 152 has a simple structure, and the locking method of the trailer hook and the connecting shell 11 is simple and convenient, which improves the convenience of use of the trailer hook assembly 1.

[0071] In some embodiments, a limiting portion 163 is further provided around the periphery of the first elastic member 161. The limiting portion 163 covers the periphery of the first elastic member 161 and is fixedly connected to the periphery of the extension section 1524 to prevent the first elastic member 161 from being separated from the connection with the extension section 1524, thereby improving the connection stability of the first elastic member 161. The limiting portion 163 can also limit the deformation direction of the first elastic member 161 to achieve the angle at which the first elastic member 161 drives the base 1523 to rotate, thereby ensuring that the first matching portion 1511 can enter the limiting notch 15231 after the second matching portion 1521 rotates, thereby ensuring that the trailer hook can be smoothly matched and connected with the connecting shell 11.

[0072] According to one embodiment of the present invention, a third inclined surface 141 suitable for cooperating with the first driving member 151 is formed on the side of the locking member 14 facing the first driving member 151, and a fourth inclined surface 1512 is formed on the first driving member 151. The fourth inclined surface 1512 is suitable for stopping with the third inclined surface 141 and pushing the locking member 14 toward the locking portion 112.

[0073] As shown in Figure 4, a third inclined surface 141 is formed on the side of the locking member 14 facing the first driving member 151, and a fourth inclined surface 1512 is formed on the first driving member 151. When the first matching portion 1511 on the first driving member 151 enters the limiting notch 15231, the fourth inclined surface 1512 and the third inclined surface 141 are stopped, and the first driving member 151 moves and pushes the locking member 14 out of the locking port 122. When the first matching portion 1511 is completely accommodated in the limiting notch 15231, the locking port 122 is facing the locking portion 112. At this time, the first driving member 151 is engaged with the third inclined surface 141 through the fourth inclined surface 1512. The inclined surface 141 stops and pushes the locking member 14 to the locking portion 112. The locking member 14 cooperates with the locking portion 112. The locking portion 112 limits the movement of the locking member 14, thereby preventing the locking member 14 from escaping the locking portion 112. The trailer hook and the connecting shell 11 are locked and connected. The present application pushes the locking member 14 and the locking portion 112 to lock through the movement of the first driving member 151, thereby realizing the locking of the trailer hook and the connecting shell 11. The structure is simple and the operation is convenient. The locking member 14 fits tightly against the inner wall of the locking portion 112, which is conducive to eliminating the abnormal noise generated by the cooperation between the trailer hook and the connecting shell 11 and improving the user experience.

[0074] According to one embodiment of the present invention, an unlocking bevel 142 is formed on the locking member 14, a locking groove suitable for accommodating the locking member 14 is formed on the locking portion 112, and a mating bevel 1121 suitable for abutting against the unlocking bevel 142 is formed on the locking groove. The mating bevel 1121 is suitable for guiding the locking member 14 into the second locking cavity 121 when the first mating portion 1511 disengages from the limiting notch 15231.

[0075] As shown in FIG4 , an unlocking inclined surface 142 is formed on the side of the locking member 14 facing the locking portion 112, and a locking groove is formed on the locking portion 112. After the first matching portion 1511 is accommodated in the limiting notch 15231, the locking member 14 enters the locking groove and is locked with the locking groove. The locking groove restricts the movement of the locking member 14 so that the locking member 14 cannot escape from the locking groove. When the trailer hook is used, the matching portion will be disengaged from the connecting shell 11. During this process, the first driving member 151 moves in a direction away from the limiting notch 15231, and the locking groove The mating bevel 1121 in the unlocking bevel 142 on the unlocking member 171 stops, and the mating bevel 1121 will provide horizontal force for the unlocking member 171 and push the locking member 14 into the locking mouth 122, so that the mating section 12 and the connecting shell 11 are disconnected from the locked state, and the trailer hook can be pulled out. In this application, the locking member 14 and the locking part 112 cooperate through the unlocking bevel 142 and the mating bevel 1121 to realize the unlocking operation of the locking member 14 and the locking part 112. The unlocking structure between the trailer hook and the connecting shell 11 is simple and easy to operate.

[0076] According to one embodiment of the present invention, a limiting groove 143 extending toward the locking portion 112 is formed on the locking member 14, and a fixed shaft 144 is provided in the second locking cavity 121. One end of the fixed shaft 144 is connected to the inner wall of the second locking cavity 121, and the other end of the fixed shaft 144 is received in the limiting groove 143 and limits the moving direction of the locking member 14.

[0077] As shown in Figure 5, a limiting groove 143 is formed on the locking member 14, which is constructed as a U-shaped groove and extends toward the locking portion 112. An open mouth facing the locking portion 112 is formed on the limiting groove 143, and a fixed shaft 144 is provided in the second locking cavity 121. One end of the fixed shaft 144 is fixedly connected to the inner wall of the second locking cavity 121, and the other end of the fixed shaft 144 extends from the open mouth into the limiting groove 143 and is accommodated in the limiting groove 143. A plurality of limiting protrusions arranged at intervals are formed on at least part of the outer periphery of the fixed shaft 144, which cooperate with the inner wall of the limiting groove 143 and limit the moving direction of the locking member 14, wherein, in the first state, the first matching portion 1511 and the second matching portion 1521 stop, and the first driving member 151 cannot be in the second state. The locking member 14 is secured in place and cannot be disengaged from the locking port 122 due to the engagement of the fixing shaft 144 with the engagement groove 143, thereby preventing the locking member 14 from disengaging from the trailer hook and ensuring the safety of the locking member 14. Furthermore, since a plurality of limiting protrusions are provided circumferentially on the fixing shaft 144, the limiting protrusions cooperate with the inner wall of the limiting groove 143 on the locking member 14 to ensure that the locking member 14 does not rotate circumferentially during the movement along the extension direction of the limiting groove 143, thereby improving the operational stability of the locking member 14 and preventing the locking member 14 from making abnormal noises with the inner wall of the locking port 122, thereby improving the user experience.

[0078] According to one embodiment of the present invention, the trailer hook assembly 1 further includes an unlocking member 171 rotatably disposed at the bottom of the second locking cavity 121 , and the unlocking member 171 can selectively drive the first driving member 151 to move along the extension direction of the second locking cavity 121 .

[0079] As shown in Figures 1 and 9, an unlocking member 171 is rotatably provided at the bottom of the second locking cavity 121, and a first matching tooth 1711 suitable for matching with the first driving member 151 is provided around the outer periphery of the unlocking member 171. A second matching tooth 1513 matching with the first matching tooth 1711 is formed on the side of the first driving member 151 facing the unlocking member 171. The first matching tooth 1711 and the second matching tooth 1513 are meshed and connected. The rotation of the unlocking member 171 can drive the first driving member 151 to move away from the second matching portion 1 along the extending direction of the second locking cavity 121. 521, and then the mating section 12 can be manually pulled out of the first locking cavity 111. As the first driving member 151 moves, the third inclined surface 141 and the fourth inclined surface 1512 no longer abut against each other, and the locking member 14 is pushed into the locking port 122 by the mating inclined surface 1121. The locking connection between the mating section 12 and the connecting shell 11 is disconnected, making it convenient to manually pull out and store the trailer hook. The present application drives the first driving member 151 to move by setting an unlocking member 171 to release the locking state of the mating section 12 and the connecting shell 11. The structure is simple and the operation is convenient.

[0080] In some embodiments, the unlocking member 171 can be constructed as a gear shaft, and a first mating tooth 1711 is arranged around the outer periphery of one end of the gear shaft facing the first driving member 151, and a key 172 hole is provided at the other end of the gear shaft. The user can insert the key 172 into the key 172 hole and rotate the gear shaft, thereby driving the first driving member 151 to move. A shaft sleeve 173 is provided on the outer periphery of the gear shaft to protect the gear shaft, and a protective sleeve 174 is provided on the outside of the key 172 hole to protect the safety of use of the key 172 hole and prevent the key 172 hole from being damaged from the outside.

[0081] In some embodiments, a fifth inclined surface 175 is formed at the end of the unlocking member 171, and a sixth inclined surface 1525 that cooperates with the fifth inclined surface 175 is formed at the end of the first driving member 151 toward the unlocking member 171. The unlocking member 171 rotates and drives the first driving member 151 to move through the fifth inclined surface 175, thereby realizing the unlocking process.

[0082] According to one embodiment of the present invention, the trailer hook assembly 1 further includes a second elastic member 162 , which is disposed between the first driving member 151 and the second locking cavity 121 .

[0083] As shown in Figure 9, a second elastic member 162 is sleeved on the first driving member 151, one end of the second elastic member 162 is fixedly connected to the first driving member 151, and the other end of the second elastic member 162 is fixedly connected to the inner wall of the second locking cavity 121. When the trailer hook is disconnected from the connecting shell 11, the first matching portion 1511 and the second matching portion 1521 stop or are located under the second matching portion 1521. At this time, the second elastic member 162 is compressed and stores elastic potential energy. The second elastic member 162 restricts the first matching portion 1511 from moving toward the second matching portion 1521. In the process of connecting the trailer hook to the connecting shell 11, the first trigger portion 113 cooperates with the second trigger portion 1522 and pushes the first trigger portion 113 to move toward the second matching portion 1521. The second trigger part 1522 rotates, the first matching part 1511 moves toward the limiting notch 15231 and is accommodated in the limiting notch 15231, the first driving member 151 moves upward, the second elastic member 162 releases elastic potential energy and generates deformation, and the second elastic member 162 can push the first matching part 1511 to move, thereby accelerating the speed at which the first matching part 1511 enters the limiting notch 15231, and making the locking member 14 move quickly to the locking part 112 and lock with the locking part 112, so that the trailer hook cannot be separated from the connecting shell 11, the connection between the trailer hook and the connecting shell 11 is stable, and the locking member 14 fits tightly against the inner wall of the locking groove, which can eliminate the abnormal noise generated by the cooperation between the trailer hook and the connecting shell 11.

[0084] In summary, according to the trailer hook assembly 1 of the present invention, the trailer hook and the connecting shell 11 are simply matched, the connection is stable, and the trailer hook is easy to plug and unplug. The present application provides a locking member 14, a first driving member 151, a second driving member 152 and an unlocking member 171 in the matching section 12, which simply and conveniently cooperates with the first triggering portion 113 and the locking portion 112 in the connecting shell 11 to achieve locking and unlocking of the trailer hook and the connecting shell 11. The trailer hook assembly 1 has a simple structure and high reliability, and the installation and disassembly operations of the trailer hook are simple. There is no shaking or abnormal noise when the trailer hook is matched with the connecting shell 11, and the user experience is better.

[0085] The trailer hook has a mating section 12 and a coupling section 13 connected to each other, wherein the coupling section 13 can be connected to other equipment so that the trailer hook can tow other equipment to move, and the other equipment can be a vehicle or cargo, etc. When the trailer hook is not in use, a ball head cap 131 can be provided at the end of the coupling section 13 to protect the trailer hook; the mating section 12 can be accommodated in the first locking cavity 111 and connected to the connecting shell 11 or disconnected from the connecting shell 11 and extracted from the first locking cavity 111, so as to achieve complete connection between the trailer hook and the vehicle cross beam. When assembling or removing the trailer hook from the vehicle cross beam, in order to ensure the stable connection between the trailer hook and the connecting shell 11, a locking member 14 is provided in the second locking cavity 121 in the trailer hook. When the mating section 12 enters the first locking cavity 111 and cooperates with the first triggering portion 113 in the first locking cavity 111, the locking member 14 will protrude from the locking opening 122 and move to the locking portion 112 in the connecting shell 11, thereby cooperating with the locking portion 112 to lock, preventing the trailer hook from being separated from the connecting shell 11 during use, thereby ensuring the safety of the trailer hook.

[0086] The first driving member 151 and the second driving member 152 are provided in the second locking cavity 121. The first driving member 151 is provided with a first matching portion 1511. The second driving member 152 is rotatably provided at one end of the first driving member 151. The second driving member 152 is provided with a second matching portion 1521 and a second triggering portion 1522. After the matching section 12 is inserted into the first locking cavity 111 and the first triggering portion 113 is matched with the second triggering portion 1522, the second triggering portion 1522 rotates, and the first matching portion 113 is connected to the second triggering portion 1522. The engaging portion 1511 and the second matching portion 1521 match and drive the first driving member 151 to move upward, and the first driving member 151 moves and pushes the locking member 14 out of the locking port 122. When the locking port 122 is aligned with the locking portion 112, the locking member 14 matches and locks with the locking portion 112 to connect and lock the trailer hook with the connecting shell 11 to prevent the trailer hook from falling off. The trailer hook connection is stable, and the locking member 14 fits tightly with the inner wall of the locking portion 112, which can eliminate the noise and abnormal sound generated when the trailer hook is matched with the connecting shell 11.

[0087] When the trailer hook is used, it is only necessary to control the first driving member 151 to move downward along the second locking cavity 121 and move the matching section 12 out of the first locking cavity 111. The movement of the first driving member 151 will cause the locking member 14 to lose support on the side away from the locking portion 112. During the manual operation of pulling the matching section 12 out of the first locking cavity 111, the matching section 12 and the connecting shell 11 move relative to each other, and the inner wall of the locking portion 112 will push the locking member 14 out and re-accommodate it in the second locking cavity 121. After the locking member 14 is disconnected from the locking portion 112, the movement of the matching section 12 in the first locking cavity 111 is unobstructed, and the trailer hook can be detached from the connecting shell 11. After the trailer hook is taken out, it can be stored in the trunk to prevent the trailer hook from being damaged by the external environment, extend the service life of the trailer hook, and ensure the aesthetics of the vehicle cross beam.
