[0058] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0059] Example 1

[0060] See also Figures 1 to 18 A fixing device is shown, which is used to be attached to a child product, which can be a child stroller, a child bed, a child seat, etc. The fixing device includes a fixing seat 1, a connecting member 2, and at least one set of locking structures, wherein the fixing seat 1 has a first mounting portion, which is configured to be connected to the child product, and the connecting member 2 is a functional product that needs to be attached to the child product, such as a control box similar to a remote control, or a storage box, etc. The connecting member 2 is detachably connected to the fixing seat 1, which is convenient for removing the connecting member 2 for separate use, and on the other hand, the connecting member 2 can also be fixed to the fixing seat 1 and stored together with the child product to avoid loss.

[0061] The locking structure includes a locking member 3 movably arranged on the fixing seat 1, and a matching portion 21 arranged on the connecting member 2, and the locking structure is used to lock the two together when the connecting member 2 is connected to the fixing seat 1. The locking member 3 has a locking portion 32, and the matching portion 21 on the connecting member 2 is used to match with the locking portion 32. The locking member 3 has a switchable first position and a second position on the fixing seat 1. When the locking member 3 is in the first position, the locking portion 32 is disengaged from the matching portion 21, and the locking member 3 fails to lock the connecting member 2 on the fixing seat 1. The locking member 3 is in an unlocked state, and the connecting member 2 can be removed from the fixing seat 1; when the locking member 3 is in the second position, the locking portion 32 and the matching portion 21 can be matched and connected with each other, so that the connecting member 2 is fixed on the fixing seat 1, and the locking member 3 is converted into a locked state.

[0062] As shown in the drawings, the fixing seat 1 also has a second mounting portion 16, and the connecting member 2 has a connecting portion 22 that cooperates with the second mounting portion 16. When the connecting member 2 and the fixing seat 1 are fixedly connected to each other, the connecting portion 22 cooperates with the second mounting portion 16, and the locking member 3 is in the second position. Specifically, the second mounting portion 16 is a circumferentially closed receiving groove, and the connecting portion 22 can be cooperatively embedded in the receiving groove and supported on the fixing seat 1. Further, the matching portion 21 of the connecting member 2 is arranged on the connecting portion 22, and the locking portion 32 of the locking member 3 is located on the second mounting portion 16, that is, when the connecting member 2 and the fixing seat 1 are cooperatively connected, the connecting portion 22 of the connecting member 2 is embedded in the receiving groove as the second mounting portion 16 to be circumferentially limited, and the locking between the two is achieved by the cooperation of the locking member 3 and the matching portion 21 at the position where the two are combined, which makes the connection between the connecting member 2 and the fixing seat 1 more reliable and stable.

[0063] Specifically, see Figure 7 , Figure 8 As shown, the fixing seat 1 includes a seat body 11 and a cover plate 12, the first mounting portion is arranged at one end of the seat body 11, and the cover plate 12 is arranged at the other end of the seat body 11. The seat body 11 has a receiving groove, the opening of which faces the side away from the first mounting portion, and the cover plate 12 is arranged in the receiving groove, and the receiving groove is divided in the depth direction to form a receiving cavity 13 and the receiving groove as described above. The locking member 3 also includes a lock seat 31 connected to the locking portion 32, the lock seat 31 is arranged in the receiving cavity 13, and the locking portion 32 passes through the through hole 121 opened on the cover plate 12 and is located in the receiving groove, so as to be matched and connected with the matching portion 21 on the connecting member 2 in the receiving groove.

[0064] As shown in the drawings, the locking member 3 can be arranged on the fixing seat 2 so as to be translatable along the first direction, and the first position and the second position are spaced apart along the first direction. The fixing device also includes an unlocking member 4, which can be slidably arranged on the fixing seat 1 along the first direction. By driving the unlocking member 4 to slide relative to the fixing seat 1, the locking member 3 can be driven to switch between the first position and the second position, and the locking and unlocking of the locking member 3 are realized accordingly.

[0065] The fixing device further comprises a driving mechanism, which is configured to provide a force required for the locking member 3 to move from the first position to the second position, so that the locking member 3 can be kept in the second position without external force, so that the locking member 3 can be kept in a locked state and the fixing seat 1 and the connecting member 2 can be kept fixed to each other. Figures 1 to 18 As shown, the driving mechanism includes an elastic member 5, which can be telescopically arranged between the locking member 3 and the fixing seat 1 along a first direction. The elastic member 5 can be specifically a spring, and its two ends are respectively against the locking member 3 and the fixing seat 1.

[0066] See also Figure 5 As shown, the lock seat portion 31 of the locking member 3 is connected with the lock portion 32 along the second direction, and the second direction is perpendicular to the first direction. The locking portion 32 includes a first lock portion 321 extending along the second direction, and a second lock portion 322 extending along the first direction from one end of the first lock portion 321, and the other end of the first lock portion 321 is connected with the lock seat portion 31. That is, the first lock portion 321 and the second lock portion 322 cooperate with each other to form a lock hook similar to a "7" shape as the locking portion 32, which is used to cooperate with the matching portion 21 to achieve locking. Here, the connecting member 2 is also provided with a lock groove 25, which is configured to allow the second lock portion 322 to be inserted and slide therein along the first direction; the matching portion 21 is a locking protrusion connected with the lock groove 25. When the locking member 3 is in the second position, the first lock portion 321 is inserted into the lock groove 25 and the second lock portion 322 is buckled on the locking protrusion, so that the connecting member 2 is mutually locked with the fixing seat 1 in the second direction.

[0067] See also Figure 5As shown, the second locking portion 322 has a push surface away from the first locking portion 321 in the second direction. The push surface is set as an inclined surface 323 here, and along the first direction, the inclined surface 323 is set to extend obliquely from the first position to the second position gradually approaching the lock seat portion 31. In this way, when the connecting member 2 is not connected to the fixing seat 1, the locking member 3 is initially maintained in the second position under the action of the spring 5; when the connecting member 2 needs to be connected to the fixing seat 1, the connecting member 2 is gradually moved closer to the fixing seat 1, the connecting member 2 contacts the second locking portion 322 of the locking member 3, and rests on the inclined surface 323; the connecting member 2 is continued to be driven closer to the fixing seat 1, then, under the action of the inclined surface 323, the locking member 3 is pushed and moves toward the first position along the first direction, so that the locking portion 32 of the locking member 3 can be inserted into the locking groove 25, and then, under the action of the spring 5, the locking member 3 moves toward the second position, so that the locking portion 31 of the locking member 3 moves toward the locking protrusion and the second locking portion 322 is engaged with the locking protrusion to achieve locking.

[0068] See also Figures 1 to 18 As shown, in this embodiment, a positioning structure is further provided between the fixing seat 1 and the connecting member 2, and the positioning structure includes a protrusion 23 and a positioning groove 17 that cooperate with each other, and one of the protrusion 23 and the positioning groove 17 is provided on the fixing seat 1 and the other is provided on the connecting member 2. Here, the protrusion 23 is provided on the connecting member 2, the positioning groove 17 is provided on the fixing seat 1, and the positioning groove 17 is connected to the accommodating groove of the second mounting portion 16.

[0069] Here, the positioning groove 17 is also configured to allow the protrusion 23 to be inserted or disengaged along the first direction, and the locking member 3 and the positioning structure are spaced apart in the first direction. This allows the fixing seat 1 and the connecting member 2 to be positioned by the positioning structure and locked by the locking member 3 in the first direction. In actual settings, the length direction of the connecting member 2 is taken as the first direction, so that the connecting member 2 is connected to the fixing seat 1 at multiple positions in the length direction, and the connection between the two is more stable and less likely to shake.

[0070] According to the solution of this embodiment, when connecting the connecting member 2 to the fixing seat 1, the operation can be carried out in the following manner: Figures 9 to 18 As shown, the connecting member 2 is first placed on one side of the fixing seat 1, and the protrusion 23 of the connecting member 2 is inserted into the positioning groove 17 along the first direction, and then the connecting member 2 is moved close to the fixing seat 1, so that the connecting portion 22 is gradually embedded in the receiving groove of the second mounting portion 16. In this process, the bottom of the connecting member 2 abuts against the inclined surface 323 of the second locking portion 322 of the locking member 2, so that the locking member 3 first moves from the second position to the first position, and then moves from the first position to the second position under the action of the spring 5. The locking portion 31 is inserted into the locking groove 25 and locked with the matching portion 21 to achieve a fixed connection between the connecting member 2 and the fixing seat 1.

[0071] In the fixing device, the first mounting portion of the fixing seat 1 is configured to be fixed on a mounting rod of the children's product. Figures 1 to 18 As shown, in this embodiment, the first mounting portion is a mounting groove 18. The fixing device also includes a buckle 6, one end of which is rotatably connected to the fixing seat 1 around the rotation center line X0. The buckle 6 has a first state and a second state. When the buckle 6 is in the first state, Figures 1 to 18 As shown, especially Figure 1 As shown, the fastener 6 and the fixing seat 1 are closed together, so that a mounting channel that can be sleeved on the mounting rod is formed between the mounting groove 18 and the fastener 6; when the fastener 6 is in the second state, the other end of the fastener 6 is away from the fixing seat 1, so that the mounting groove 18 is open outward, so that the mounting rod can be inserted into or removed from the mounting groove 18. In a specific setting, the inner groove surface of the mounting groove 18 is arc-shaped, and the fastener 6 is also an arc-shaped component. The mounting channel formed when the two cooperate with each other can allow the cylindrical mounting rod to pass through along the axial direction. In a specific setting, the mounting groove 18 is formed by the fixing seat 1 extending in the direction away from the connecting member 2, and one end of the fastener 6 is rotatably connected to the groove wall of one end of the mounting groove 18. The cross-section of the mounting groove 18 can be set to be semicircular, and the fastener 6 is also formed on the fastener 6. When the fastener 6 and the fixing seat 1 are closed, a mounting channel for the cylindrical rod to be correspondingly inserted and engaged therein can be formed between the fastener 6 and the mounting groove 18.

[0072] The fixing device also includes a lock assembly disposed between the buckle 6 and the fixing seat 1 and used to lock the buckle 6 in the first state. Here, the lock assembly includes a lock 8 and an operating handle 7. One end of the operating handle 7 is rotatably connected to the other end of the buckle 6 around the first axis X1. The fixing seat 1 is provided with a hook portion 19. One end of the lock 8 is rotatably connected to the operating handle 7 around the second axis X2. The other end of the lock 8 can be cooperatively hooked on the hook portion 19. The first axis X1, the second axis X2 and the rotation center line X0 are parallel to each other. When the buckle 6 is in the first state, the hook portion 19, the first axis X1 and the second axis X2 are sequentially distributed. By driving the operating handle 7 to rotate, the lock 8 can be moved toward or away from the hook portion 19, so that the lock 8 is hooked on the hook portion 19 or disengaged from the hook portion 19, thereby switching the buckle 6 between the first state and the second state.

[0073] In this embodiment, the connector 2 is specifically a control box, which is connected to the electronic control device provided on the children's product by signal, and is usually provided with a control module, an operation panel, an indicator light, a communication module, etc. The control box has a box body, and the box body has a first end 2A and a second end 2B respectively provided at two different ends in the thickness direction of the box body. The first end 2A is provided with an operation panel 24, and the operation panel 24 can be a button type or a touch type, or can be other control operation modes. The second end 2B is used to connect with the fixing seat 1, and the connecting part 22 is provided on the second end 2B. The installation connection between the fixing seat 1 and the connector 2 will not affect the operation of the operation panel 24.

[0074] Example 2

[0075] See also Fig.19 As shown, the difference between this embodiment and embodiment 1 mainly lies in that, in this embodiment, on the one hand, no positioning structure is provided between the fixing base 1 and the connecting member 2; on the other hand, two groups of locking members 3 are provided on the fixing base 1, and the two groups of locking members 3 are both provided on the fixing base 1 for translational movement along the first direction, and the two groups of locking members 3 are spaced apart from each other in the first direction, and accordingly, two groups of matching portions 21 on the connecting member 2 are also provided.

[0076] See also Fig. 20 As shown, two sets of unlocking members 4 are also provided on the fixing seat 1, which are respectively connected with the two sets of locking members 3 to drive the two sets of locking members 3 to translate along the first direction. The two sets of locking members 3 can move in the same direction or in opposite directions along the first direction. Fig.21 As shown, only one set of unlocking members 4 can be provided on the fixing seat 1, which is only used to unlock one set of locking members 3, while the other set of locking members 3 drives the connecting member 2 and the fixing seat 1 to translate along the first direction after driving the previous set of locking members 3 to unlock, so as to disengage from the cooperation with the matching portion 21 and realize unlocking. Alternatively, the two sets of locking members 3 can be arranged in linkage, so that when one set of locking members 3 is driven to move along the first direction, the other set of locking members 3 will also move synchronously.

[0077] In other embodiments, when the length of the connecting member 2 in the first direction is longer, the number of the locking members 3 can be more than two groups, and all the locking members 3 are spaced apart from each other in the first direction to improve the stability of the connection between the fixing base 1 and the connecting member 2.
