[0072] First embodiment

[0073] See also Figures 1 to 4 , schematically shows a side impact protection block and a mounting seat 5 matched with the side impact protection block provided by the first embodiment of the present invention. Fig.32 The side impact protection block 100 and the mounting seat 5 are used to be installed on the side wing 91 of the child safety seat 9. The child safety seat 9 can be installed in the interior of a car or other means of transportation. In this article, the child safety seat 9 is explained by taking the application in a car as an example. When the car is emergency braked or accidentally collides, the side impact protection block 100 contacts the inner wall of the vehicle to suppress and cushion the lateral movement of the child safety seat, thereby providing enhanced protection for the child sitting in the child safety seat 9. It should be noted that in this article, the child safety seat can be understood as a superordinate term for child safety seat and infant car seat. Child can be understood as a superordinate term for infants and children. Combined with reference Fig.33 The mounting seat 5 is fixedly arranged on the side wing 91 of the child safety seat 9 , and the side impact protection block 100 can be detachably mounted to the mounting seat 5 .

[0074] The side impact protection block 100 mainly includes a housing 1, a button 2 and a locking member 3, and the number of each of the button 2 and the locking member 3 may not be limited to one. The housing 1 may include a top wall 11, a side wall 12 and a bottom wall 13. The top wall 11 includes a side impact contact surface 110, which is used to contact the inner side wall of the vehicle when the child safety seat 9 has a tendency to move laterally, thereby limiting the lateral movement of the child safety seat 9. It can be understood that, depending on the specific installation position of the child safety seat in the rear seat of the vehicle, usually only the side impact protection block 100 on one side of the child safety seat plays a role in preventing lateral movement. Because the side impact protection block 100 is detachably connected to the mounting seat 5, in this way, both side wings 91 of a child safety seat 9 can be fixedly provided with a mounting seat 5, and two mounting seats 5 can be configured with only one side impact protection block 100, which is installed in the mounting seat 5 on either side of the child safety seat 9 as required. It should be noted that, although in the present embodiment, the side impact contact surface 110 is a relatively gentle arc surface, in other embodiments, the surface shape of the side impact contact surface 110 is not limited thereto, as long as it can contact the inner side of the vehicle to inhibit lateral movement.

[0075] See also Figure 1 , the button 2 is arranged on the side wall 12 of the housing 1, and the locking member 3 is arranged on the side wall 12 of the housing 1 and has a locking portion. The button 2 is used to withstand the pressing force and is operably connected to the locking member 3, so that the locking member 3 has a locked state and an unlocked state. It should be noted that the operably connected in this application includes but is not limited to direct connection, indirect connection, fixed connection, pivot connection, pressing contact, etc. When two components are operably connected together, it means that the action of one component can cause the other component to act.

[0076] See also Figures 2 to 4In this embodiment, the locking member 3 may include a first elastic arm 31 integrally formed with the side wall 12 of the housing 1, the first end 3101 of the first elastic arm 31 is close to the top wall 11 and is a connecting end, and the second end 3102 of the first elastic arm 31 is close to the bottom wall 13 and is a free end. The locking portion includes a first hook 3a1 arranged at the free end. The button 2 is located in the middle of the first elastic arm 31, and the button 2 can be integrally formed with the first elastic arm 31, or the button 2 can be attached to the middle of the first elastic arm 31. In this way, the button 2 is in the initial position when it is not subjected to a pressing force, and the first hook 3a1 of the first elastic arm 31 is in a locked state. When the button 2 is pressed from the initial position to the pressed position by a pressing force, the first elastic arm 31 is driven by the button 2 to undergo elastic deformation, so that the first hook 3a1 moves toward the interior 10 of the housing 1 and changes from a locked state to an unlocked state. When the pressing force on the button 2 is released, the first elastic arm 31 elastically recovers, so that the button 2 can elastically recover to the initial position, and the first hook body 3a1 can elastically recover to the locked state.

[0077] See also Figure 3 and Figure 4 The mounting seat 5 has a mounting groove 50, and the mounting groove 50 is used to accommodate a portion of the housing 1 of the side impact protection block 100. It can be understood that the bottom wall 13 and at least a portion of the side wall 12 of the housing 1 are accommodated in the mounting groove 50. A locking hole 5011 is provided on the side wall 501 of the mounting groove 50, and the locking hole 5011 is used to match the locking portion of the locking member 3. More specifically, in this embodiment, the locking hole 5011 is used to match the first hook body 3a1 of the first elastic arm 31.

[0078] See also Figure 2 When the side impact protection block 100 needs to be installed on the mounting seat 5, the button 2 is pressed to elastically deform the first elastic arm 31, so that the first hook 3a1 changes to an unlocked state. Then, the side impact protection block 100 is inserted into the mounting groove 50 along the direction of the arrow P, and the first hook 3a1 also enters the mounting groove 50. It can be understood that by making the first hook 3a1 have a wedge-shaped surface, the side impact protection block 100 can be inserted into the mounting groove 50 without actively pressing the button 2.

[0079] See also Figure 4When the side impact protection block 100 is inserted into place, the pressing force on the button 2 is released, the first elastic arm 31 elastically recovers, the first hook body 3a1 changes to a locked state and locks with the locking hole 5011 on the side wall 501 of the installation groove 50, and the button 2 elastically recovers to the initial position, thereby preventing the side impact protection block 100 from accidentally falling off from the installation groove 50. When the side impact protection block 100 needs to be removed from the installation groove 50, a pressing force is applied to the button 2, and the first elastic arm 31 is elastically deformed again, so that the first hook body 3a1 and the locking hole 5011 are released from the locking cooperation, and the side impact protection block 100 can be freely removed from the installation groove 50.

[0080] This embodiment provides a side impact protection block 100 with a simple structure and low cost. The side impact protection block 100 and the mounting seat 5 are easy to install and remove, so that consumers can selectively configure one or more replacement side impact protection blocks 100 for the child safety seat 9 as needed.

[0081] Combined with reference Figures 2 to 4 In some embodiments, the housing 1 includes a first housing portion 101 and a second housing portion 102. The first housing portion 101 is a hollow structure with an open bottom. The top wall 1011 of the first housing portion 101 forms the top wall 11 of the housing 1. The side impact contact surface 110 is located on the top wall 1011 of the first housing portion 101. The side wall 1012 of the first housing portion 101 forms the side wall 12 of the housing 1. The first elastic arm 31 is integrally formed with the side wall 1012 of the first housing portion 101. The second housing portion 102 is buckled into the bottom opening of the first housing portion 101. The bottom wall 1023 of the second housing portion 102 can close the bottom opening of the first housing portion 101 and form the bottom wall 13 of the housing 1. The second housing portion 102 also includes a first rib plate group 1021 extending from the bottom wall 1023 into the interior of the first housing portion 101. The first rib plate group 1021 has the effect of reinforcing the structural strength of the first housing portion 101. The first rib plate group 1021 may include a first limiting plate 10211 corresponding to the first elastic arm 31 , and the first limiting plate 10211 may effectively prevent the first elastic arm 31 from being damaged due to excessive pressure.

[0082] It should be noted that, in some embodiments not shown, the shell 1 may not include the second shell portion 102. In this case, the bottom wall of the first shell portion 101 forms the bottom wall 13 of the shell 1, and the bottom wall of the first shell portion 101 may be open or closed.

[0083] Combined with reference Figures 1 to 4In some embodiments, an end cover 51 may be provided in the mounting groove 50 of the mounting seat 5. When the side impact protection block 100 is not installed in the mounting groove 50, the end cover 51 is used to close the opening of the mounting groove 50. The end cover 51 may be supported at the open end of the mounting groove 50 by at least one fourth elastic member 53 in the mounting groove 50, for example. When the side impact protection block 100 is installed in the mounting groove 50, the end cover 51 is pressed by the bottom wall 13 of the housing 1 to compress the fourth elastic member 53, and the end cover 51 moves toward the bottom 502 of the mounting groove 50. At the same time, the locking hole 5011 on the side wall 501 of the mounting groove 50 is exposed and can be locked with the locking portion of the locking member 3 of the side impact protection block 100 (more specifically, the first hook body 3a1 of the first elastic arm 31).

[0084] See also Figure 3 In some embodiments, one or more third elastic arms 511 may be provided on the end cover 51, and the third elastic arm 511 has a hook 511a. The side wall 501 of the mounting groove 50 may be provided with one or more second sliding holes 5012. The hook 511a can be engaged with the locking end 5012a of the second sliding hole 5012 to limit the end cover 51 to a position that closes the opening of the mounting groove 50. When the end cover 51 is subjected to a pressing force, the hook 511a can move along the second sliding hole 5012 to allow the side impact protection block 100 to be inserted into the mounting groove, and to allow the locking hole 5011 to be exposed to cooperate with the locking portion of the locking member 3.

[0085] In some embodiments, the fourth elastic member 53 may include two springs arranged at intervals to provide sufficient supporting force for the end cover 51 with a larger area. Of course, the fourth elastic member 53 may include only one spring or more springs.

[0086] In some embodiments, at least one locking hole 5011 may overlap with a locking end 5012a of at least one second sliding hole 5012, which helps to simplify the manufacturing process.

The button 2 is operably connected to the locking member 3 so that the locking portion of the locking member 3 can be switched between a locked state and an unlocked state.

[0090] See also Figure 7 The shell 1 may be composed of two shell parts, namely a third shell part 103 and a fourth shell part 104. The third shell part 103 may be hollow and open at the bottom. The top wall 1031 of the third shell part 103 forms the top wall 11 of the shell 1, the side impact contact surface 110 is located on the top wall 1031 of the third shell part 103, and the side wall 1032 of the third shell part 103 forms the side wall 12 of the shell 1. The fourth shell part 104 is snapped into the bottom opening of the third shell part 103. The bottom wall 1043 of the fourth shell part 104 can close the bottom opening of the third shell part 103 and form the bottom wall 13 of the shell 1. The fourth shell part 104 also includes a second rib plate group 1042 extending from the bottom wall 1043 into the interior of the third shell part 103, and the second rib plate group 1042 serves to strengthen the structural strength of the third shell part 103.

[0091] See also Figure 5 , Figure 7 and Figure 8 The button 2 is disposed in a button hole 120 connected to the side wall 1032 of the third housing portion 103, and at least a portion of the hole wall of the button hole 120 may be formed by the side wall 1032. The button 2 has an outer end 21 for bearing a pressing force and an inner end 22 located in the interior 10 of the housing 1. For example, in some embodiments, the side wall 1032 is provided with a first hole section 120a that is slidably matched with the button 2, and the second rib plate group 1042 includes an annular extension plate 10421, which defines a second hole section 120b that is slidably matched with the button 2, and the first hole section 120a and the second hole section 120b are connected to form the button hole 120. Of course, in some other embodiments, the annular extension plate 10421 may not be disposed on the second rib plate group 1042, but may be integrally formed with the side wall 1032.

[0092] See also Fig. 9 and Fig.10, two locking members 3 are located in the interior 10 of the housing 1, the two locking members 3 are arranged substantially symmetrically in the interior 10 of the housing 1, and are operably connected to the same button 2. The first end 301a of the locking member 3 contacts the inner end 22 of the button 2, wherein the contact surface of the inner end 22 of the button 2 for contacting the first end 301a is an inclined surface 220, and the inclined surface 220 faces the top wall 1031 of the third housing portion 103. The middle part of each locking member 3 is pivotally connected to the housing 1 through a first pin shaft 391, and the first pin shaft 391 is, for example, installed in a hole 10420 of the second rib plate group 1042. The locking portion includes a second hook body 3a2 located at the second end 302a of the locking member 3, and the second hook body 3a2 is folded toward the side wall 1032.

[0093] In some embodiments, the locking member 3 may be generally L-shaped, including a first arm 301, a corner portion 303, and a second arm 302 connected in sequence. The free end of the first arm 301 forms the first end 301a of the locking member 3, the first pin 391 is disposed at the corner portion 303, and the free end of the second arm 302 forms the second end 302a of the locking member 3. The locking member 3 of this configuration occupies a smaller volume and has a more reasonable structure.

[0094] The side wall 1032 of the third housing portion 103 is provided with a first through hole 1201 for the second hook 3a2 to extend out, and the interior 10 of the housing 1 is also provided with a first elastic member 41. Figure 8 and Fig. 9 When the button 2 is in the initial position, the tip area of ​​the inclined surface 220 contacts the first end 301a of the locking member 3, and the first elastic member 41 acts on the locking member 3 to keep the second hook 3a2 in the locked state extending from the first through hole 1201. At this time, the second hook 3a2 is locked and matched with the locking hole 5011 of the mounting seat 5, and the side impact protection block 100 cannot be removed from the mounting groove 50. Figure 8 and Fig.10 When the outer end 21 of the button 2 is pressed and the button 2 switches from its initial position to the pressed position, the inclined surface 220 of the button 2 pushes the first arm 301, so that the locking member 3 overcomes the force of the first elastic member 41 and pivots around the first pin 391, so that the second hook body 3a2 switches to an unlocked state retreating from the first through hole 1201. At this time, the side impact protection block 100 can be easily removed from the mounting groove 50.

[0095] It can be understood that when the side impact protection block 100 needs to be inserted into the mounting groove 50 of the mounting seat 5, the button 2 can be pressed to unlock the second hook 3a2 of the locking member 3, and then the side impact protection block 100 can be moved along the Figure 6The side impact protection block 100 is inserted into the installation groove 50 in the direction of the arrow P in the figure, and then the pressing force is released to lock the second hook body 3a2 and the locking hole 5011. Of course, by making the second hook body 3a2 have a wedge-shaped surface, the side impact protection block 100 can also be inserted into the installation groove 50 without actively pressing the button 2.

[0096] See also Figure 7 , Fig. 9 and Fig.10 In some embodiments, the first elastic member 41 includes a reset contact strip connected to the second arm 302 of the locking member 3, and a limiting wall 10422 in contact with the reset contact strip is provided in the interior 10 of the housing 1. When the button 2 is pressed to the pressed position, the locking member 3 pivots under the action of the inclined surface 220, which not only switches the second hook body 3a2 from the locked state to the unlocked state, but also causes the reset contact strip to elastically deform. When the button 2 elastically returns to the initial position, the reset contact strip automatically elastically returns and drives the locking member 3 to pivot around the first pin 391, so that the second hook body 3a2 elastically returns to the locked state and remains in the locked state.

[0097] In some embodiments, the free end of the reset contact strip contacts the limiting wall 10422, and the other end opposite to the free end extends to the locking member 3, that is, the reset contact strip and the corresponding locking member 3 can be an integrally formed part. The limiting wall 10422 can be formed by the wall body of some ribs of the second rib group 1042.

[0098] The moving direction of the button 2 can be substantially parallel to the extending direction of the first pin 391, which is convenient for manufacturing. It should be noted that, although in this embodiment, the inclined surface 220 is formed on the inner end 22 of the button 2 to promote the rotation of each locking member 3, it can be understood that in other embodiments, the inclined surface can be set on the first end 301a of the locking member 3, or the inclined surface can be set on the inner end 22 of the button 2 and the first end 301a of the locking member 3 at the same time, so that when the button 2 is pressed from the initial position to the pressed position, the inner end 22 of the button 2 and the first end 301a of the locking member 3 can promote the rotation of the locking member 3 through the contact of the inclined surface, so that the second hook body 3a2 can be switched from the locked position to the unlocked position.

[0099] It should be noted that, although in the present embodiment, the first elastic member 41 is described by taking the reset contact strip as an example, in other embodiments, the first elastic member 41 may also have other implementations. For example, the first elastic member 41 may adopt a spring arranged between the second arm 302 and the limiting wall 10422, or, it may adopt a torsion spring arranged between the first pin shaft 391 and the locking member 3.

[0100] In some embodiments, a first movement limiting structure 201 may be provided between the button 2 and the housing 1, and the first movement limiting structure 201 is used to limit the travel of the button 2 between the initial position and the pressed position, and also to prevent the button 2 from falling off from the button hole 120. There are many embodiments of the first movement limiting structure 201. For example, in one embodiment, see Figure 7 and Figure 8 The first movement limiting structure 201 may include a limiting hole 2010 and a second elastic arm 2012. The limiting hole 2010 may be formed on the hole wall of the button hole 120, for example, formed on the annular extension plate 10421 (the annular extension plate 10421 defines the second hole section 120b of the button hole 120). The second elastic arm 2012 may be integrally formed with the button 2, the first end 2012a of the second elastic arm 2012 is close to the outer end 21 of the button 2 and is a connecting end, and the second end 2012b of the second elastic arm 2012 is close to the inner end 22 of the button 2 and is a free end. A boss 20121 that slidably cooperates with the limiting hole 2010 is provided at the second end 2012b of the second elastic arm 2012, and the end of the limiting hole 2010 can limit the sliding position of the boss 20121, thereby limiting the stroke of the button 2.

[0101] See also Figure 8 In some embodiments, a second elastic member 42 for keeping the button 2 in the initial position may be provided between the button 2 and the housing 1, and the second elastic member 42 helps the button 2 to elastically return to the initial position from the pressed position. It is understandable that in some embodiments, the second elastic member 2 may not be provided, because when the locking member 3 pivots around the first pin 391 under the elastic recovery action of the first elastic member 41, the first arm 301 will press the inclined surface 220 to push the button 2 to elastically return to the initial position.

[0102] The second elastic member 42 may be a spring. In some embodiments, a groove 20 for accommodating the second elastic member 42 is provided in the middle of the button 2, and the outer end 20a of the groove 20 limits the outer end of the second elastic member 42. A protrusion 1200 suitable for pressing the inner end of the second elastic member 42 is provided on the hole wall of the button hole 120. It can be understood that the protrusion 1200 does not affect the movement of the button 2 between the initial position and the pressing position. In this way, when the button 2 is pressed to the pressing position, the second elastic member 42 is compressed between the outer end 20a of the groove 20 and the protrusion 1200 (the wall of the groove 20 has an opening for the protrusion 1200 to extend into the groove 20). When the pressing force on the button 2 is released, the second elastic member 42 automatically elastically recovers and drives the button 2 to elastically recover to the initial position. In some embodiments, a boss 1200a may also be provided on the protrusion 1200, and the inner end of the second elastic member 42 may be sleeved on the boss 1200a.

[0103] It should be noted that, although in the present embodiment, two locking members 3 are operably connected to the same button 2 , in other embodiments, one button 2 may be used to be operably connected to one locking member 3 .

Each locking member 3 may include a first arm 301, a corner portion 303, and a second arm 302 connected in sequence. The free end of the first arm 301, as the first end 301a of the locking member 3, contacts the inner end 22 of the button 2. The contact surface of the inner end 22 of the button 2 for contacting the free end 301a of the first arm 301 is an inclined surface 220, and the inclined surface 220 faces away from the top wall 1031 of the third housing portion 103. The corner portion 303 is located in the middle of the locking member 3 and is pivotally connected to the housing 1 through a first pin 391, and the first pin 391 is, for example, installed in the hole 10420 of the second rib plate group 1042. The locking portion includes a second hook body 3 a 2 located at the free end of the second arm 302 (ie, the second end 302 a of the locking member 3 ), and the second hook body 3 a 2 is folded toward the side wall 10432 .

[0110] The first through hole 1201 is formed on the side wall 10432 of the recess 10430. The interior 10 of the housing 1 is further provided with a first elastic member 41, which may be a reset contact strip formed integrally with the first arm 301 of the locking member 3. One end of the reset contact strip is, for example, connected to the free end 301a of the first arm 301, and the other end of the reset contact strip is, for example, in contact with a limiting wall 10422 of the interior 10 of the housing 1, which may be, for example, formed by a wall of a part of the ribs of the second rib plate group 1042 or formed by a part of the surface of the recess 10430 in the interior 10 of the housing 1. The first elastic member 41 acts on the locking member 3 to keep the second hook 3a2 in a locked state extending from the first through hole 1201.

[0111] See also Fig.12 , Fig.18 and Fig.19In this embodiment, the mounting groove 50 of the mounting groove 5 is provided with a protrusion 55 for inserting into the recess 10430 of the fourth housing portion 104, and the protrusion 55 may be a hollow structure. The side wall 501 of the mounting groove 50 includes an outer peripheral side wall 501a and an inner peripheral side wall 501b, and a locking hole 5011 for locking and cooperating with the second hook body 3a2 of the locking member 3 is provided on the inner peripheral side wall 501b. The opening of the mounting groove 50 is annular, and an annular end cover 51 may be provided in the mounting groove 50. Similar to the above-mentioned second embodiment, the end cover 51 can be supported at the open end of the mounting groove 50 by the fourth elastic member 53, and when subjected to a pressing force, it moves toward the bottom of the mounting groove 50 to expose the locking hole 5011. Fig.19 , which is a three-dimensional schematic diagram showing that the end cover 51 is pressed against the bottom of the mounting groove 50. Similar to the first and second embodiments, the end cover 51 may be provided with a third elastic arm having a hook, and the hook of the third elastic arm may be slidably matched with the second sliding hole 5012 of the inner peripheral side wall 501b, for example. In addition, the locking end 5012a of at least one second sliding hole 5012 may overlap with at least one locking hole 5011.

[0112] See also Fig.14 and Fig.15 When the button 2 is in the initial position, the tip area of ​​the inclined surface 220 contacts the first end 301a of the locking member 3, and the first elastic member 41 acts on the locking member 3 to keep the second hook 3a2 in the locked state extending from the first through hole 1201. At this time, the second hook 3a2 is locked and matched with the locking hole 5011 of the mounting seat 5, and the side impact protection block 100 cannot be removed from the mounting groove 50. Fig.14 and Fig.16 When the outer end 21 of the button 2 is pressed and switched from its initial position to the pressed position, the inclined surface 220 of the button 2 presses the first arm 301, so that the locking member 3 overcomes the force of the first elastic member 41 and pivots around the first pin 391, so that the second hook 3a2 switches to the unlocked state of retreating from the first through hole 1201. At this time, the side impact protection block 100 can be easily removed from the mounting groove 50. When the side impact protection block 100 needs to be inserted into the mounting groove 50 of the mounting seat 5 again, the side impact protection block 100 is moved along the mounting groove 50. Fig.12 Insert it into the mounting groove 50 in the direction of arrow P.

[0113] Similar to the above second embodiment, the moving direction of the button 2 is substantially parallel to the extending direction of the first pin, and a first movement limiting structure 201 may be provided between the button 2 and the housing 1 (see Figure 7), the first movement limiting structure 201 is used to limit the travel of the button 2 between the initial position and the pressed position, and can also prevent the button 2 from falling off from the button hole 120. A second elastic member 42 for keeping the button 2 in the initial position can also be arranged between the button 2 and the housing 1, and the second elastic member 42 helps the button 2 to elastically return from the pressed position to the initial position. The implementation of the first movement limiting structure 201 and the second elastic member 42 will not be repeated here.

[0114] It should be noted that, although in this embodiment, two locking members 3 are operably connected to the same button 2, in other embodiments, one button 2 can be used to be operably connected to one locking member 3. In addition, in this embodiment, although the inclined surface 220 is formed on the inner end 22 of the button 2 to promote the rotation of each locking member 3, it can be understood that in other embodiments, an inclined surface can be provided on the first end 301a of the locking member 3, or an inclined surface can be provided on both the inner end 22 of the button 2 and the first end 301a of the locking member 3, so that when the button 2 is pressed from the initial position to the pressed position, the inner end 22 of the button 2 and the first end 301a of the locking member 3 can promote the rotation of the locking member 3 through the contact of the inclined surface, so that the second hook 3a2 can be switched from the locked position to the unlocked position. In addition, the implementation of the first elastic member 41 is not limited to the reset contact strip.

[0115] Fourth embodiment

[0116] See below Figure 20 to Figure 25 , schematically shows a side impact protection block 100 and a mounting seat 5 matched with the side impact protection block 100 provided in a fourth embodiment of the present invention. The main difference between this embodiment and the first embodiment is the structure of the side impact protection block 100.

[0117] See also Fig.21 , Figure 23 to Figure 25 The mounting seat 5 has a mounting groove 50 similar to other embodiments, and the mounting groove 50 is used to accommodate a portion of the housing 1 of the side impact protection block 100. The bottom wall 13 and at least a portion of the side wall 12 of the housing 1 are accommodated in the mounting groove 50. A locking hole 5011 is provided on the side wall 501 of the mounting groove 50, and the locking hole 5011 is used to match the locking portion of the locking member 3.

[0118] An end cap 51 may be provided in the mounting groove 50 of the mounting seat 5. When the side impact protection block 100 is not installed in the mounting groove 50, the end cap 51 is used to close the opening of the mounting groove 50. The end cap 51 may be supported at the open end of the mounting groove 50 by, for example, at least one fourth elastic member 53 in the mounting groove 50. When the side impact protection block 100 is installed in the mounting groove 50, the end cap 51 is pressed by the bottom wall 13 of the housing 1 to compress the fourth elastic member 53, and the end cap 51 moves toward the bottom 502 of the mounting groove 50. At the same time, the locking hole 5011 on the side wall 501 of the mounting groove 50 is exposed and can be locked with the locking portion of the locking member 3 of the side impact protection block 100.

[0119] One or more third elastic arms 511 may be provided on the end cover 51, and the third elastic arm 511 has a hook 511a. The side wall 501 of the mounting groove 50 may be provided with one or more second sliding holes 5012. The hook 511a can be engaged with the locking end 5012a of the second sliding hole 5012 to limit the end cover 51 to a position that closes the opening of the mounting groove 50. When the end cover 51 is subjected to a pressing force, the hook 511a can move along the second sliding hole 5012 to allow the side impact protection block 100 to be inserted into the mounting groove 50, and to allow the locking hole 5011 to be exposed to cooperate with the locking portion of the locking member 3.

[0120] In some embodiments, the fourth elastic member 53 may include two springs arranged at intervals to provide sufficient supporting force for the end cover 51 with a larger area. Of course, the fourth elastic member 53 may include only one spring or more springs.

[0121] In some embodiments, at least one locking hole 5011 may overlap with a locking end 5012a of at least one second sliding hole 5012, which helps to simplify the manufacturing process.

The sixth housing part 106 includes a second hollow cavity 1060 with an open top and an extension plate 1061 at the top port of the second hollow cavity 1060, the extension plate 1061 extends outward from the top port of the second hollow cavity 1060 and can be buckled in the bottom opening of the fifth housing part 105, the sixth housing part 106 has a side wall 1062, and the bottom wall 1063 of the sixth housing part 106 forms the bottom wall 13 of the housing 1. The sixth shell portion 106 may further include a third rib group 1064 located on the extension plate 1061 , and the third rib group 1064 extends into the first hollow cavity 1050 to enhance the structural strength of the fifth shell portion 105 .

[0123] The interior 10 of the housing 1 may be surrounded by a first hollow cavity 1050 and a second hollow cavity 1060. The side wall 12 of the housing 1 includes a side wall 1052 of the fifth housing portion 105 and a side wall 1062 of the sixth housing portion 106. The button 2 is disposed in a button hole 120 connected to the side wall 12 of the housing 1. In this embodiment, the button hole 120 is connected to the side wall 1052 of the fifth housing portion 105. The outer end 21 of the button 2 is adapted to receive a pressing force, and the inner end 22 of the button 2 extends into the interior 10 of the housing 1. In this embodiment, see Fig.23 When the button 2 is in the initial position, its outer end 21 protrudes from the side wall 1052, for example.

[0124] See also Fig.23 and Fig.24 The locking member 3 may include a first locking member 311 located in the interior 10 of the housing 1, and the first end 311a of the first locking member 311 is pivotally connected to the inner end 22 of the button 2 through the third pin 393, so that the first end 311a of the first locking member 311 is operably connected to the button 2. The locking portion may include a third hook 3a3 disposed at the second end 311b of the first locking member 311, and the middle portion of the first locking member 311 is pivotally connected to the housing 1 through the second pin 392, and the second pin 392 may be installed in the hole 1045 of the third rib plate group 1064, for example. The side wall 12 of the housing 1 is provided with a second through hole 1202 for the third hook 3a3 to extend out, and the second through hole 1202 is, for example, disposed on the side wall 1062 of the sixth housing portion 106.

[0125] The interior 10 of the housing 1 may also be provided with a third elastic member 43, which acts on the first locking member 311 to keep the third hook 3a3 in a locked state extending from the second through hole 1202 and to keep the button 2 in the initial position. When the outer end 21 of the button 2 is pressed and changes from the initial position to the pressed position, the inner end 22 of the button 2 drives the first locking member 311 to overcome the force of the third elastic member 43 and pivot around the second pin 392, so that the third hook 3a3 switches to an unlocked state retreating from the second through hole 1202. When the pressing force on the button 2 is released, the third elastic member 43 automatically drives the first locking member 311 to rotate around the second pin 392, so that the third hook 3a3 elastically returns to the locked state and the button 2 elastically returns to the initial position. In some embodiments, the third elastic member 43 may be provided, for example, between the first locking member 311 and part of the ribs of the third rib group 1064.
