DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0053] Some embodiments of the utility model will be described in detail below with reference to the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0054] In combination Figure 1 And Figure 2 The utility model embodiment provides a telescopic structure 100, which can be used for the interior decoration of a vehicle. The telescopic structure 100 has two states of extension and retraction, and a user can freely switch between the two states of extension and retraction. Figure 1 The schematic view of the retraction state is shown in Figure 1, Figure 2 The schematic view of the extension state is shown in Figure 2. When in the extension state, it can be used as a hook for hanging and placing articles, and plays a role of article storage. When not in use, the telescopic structure 100 can be switched to the retraction state, the structure is compact, occupies small space, and meets the needs of interior decoration simplification. Of course, the telescopic structure 100 can be used not only for vehicle interior decoration, but also for other article hanging use scenarios.

[0055] In combination Figure 3The telescopic structure 100 comprises a base 110, a telescopic part 120 and a locking part 130. The telescopic part 120 is movable relative to the base 110 to realize the extension or retraction of the telescopic part 120 relative to the base 110. The locking part 130 is arranged on the base 110. When the telescopic part 120 is in the retracted state, the locking part 130 cooperates with the telescopic part 120 to keep the telescopic part 120 in the retracted state. When the telescopic part 120 is in the extended state, the locking part 130 is disengaged from the telescopic part 120. The telescopic structure 100 has compact structure and occupies small space. The two states of extension and retraction can be switched freely, and the use is more flexible and convenient. The structure has good reliability and meets the requirement of the simplification of the vehicle interior.

[0056] The telescopic part 120 and the base 110 are in linear sliding cooperation to realize the extension or retraction of the telescopic part 120 relative to the base 110. The linear sliding cooperation is adopted, and the telescopic part 120 can make linear reciprocating motion. The structure is compact and occupies small space. Compared with some existing turnover hook structures, the turnover space does not need to be reserved, and the structure is more simple.

[0057] In combination with Figure 4 and Figure 5 Optionally, the telescopic part 120 comprises a push rod 121, and the base 110 is provided with a first mounting hole 111. The push rod 121 is slidably arranged in the first mounting hole 111 to realize the extension or retraction of the push rod 121 relative to the base 110.

[0058] Optionally, the telescopic part 120 is provided with a first buckle 123, and the base 110 is provided with a second buckle 112 having elasticity. When the telescopic part 120 is in the retracted state, the first buckle 123 and the second buckle 112 are separated. When the telescopic part 120 is in the extended state, the first buckle 123 and the second buckle 112 abut. The second buckle 112 adopts an elastic structure, i.e. the second buckle 112 has a certain elastic deformation capacity and can be elastically deformed under the action of external force. When the external force disappears, it can recover to the state before deformation. In this way, the telescopic part 120 can be smoothly loaded into the base 110. In the extended state, the first buckle 123 and the second buckle 112 abut, which can axially limit the telescopic part 120 and prevent the telescopic part 120 from being separated from the base 110. The elastic deformation capacity of the second buckle 112 can be realized by the material properties or structural properties of the second buckle 112 itself, or by connecting some elastic elements such as springs and elastic sheets, which are not limited here.

[0059] Optionally, the telescopic part 120 comprises a first limiting part 122 connected with the push rod 121, and the first buckle 123 is arranged on the first limiting part 122. The first limiting part 122 is connected to one end of the push rod 121 and extends along the axial direction of the push rod 121.

[0060] Optionally, the first latch 123 includes a first guide slope 1231 and a first stop surface 1232 connected together; the second latch 112 includes a second guide slope 1121 and a second stop surface 1122 connected together. The first guide slope 1231 can abut against the second guide slope 1121 to cause the second latch 112 to deform; when the telescopic member 120 is in the retracted state, the second latch 112 returns to its original deformation; when the telescopic member 120 is in the extended state, the first stop surface 1232 and the second stop surface 1122 abut against each other. It is understandable that during the assembly of the telescopic component 120 and the base 110, when the push rod 121 slides along the first mounting hole 111, the first guide slope 1231 contacts the second guide slope 1121. As the push rod 121 continues to slide, the first latch 123 presses against the second latch 112, causing the second latch 112 to deform radially outward from the first mounting hole 111. The first latch 123 smoothly passes over the second latch 112, and there is a certain distance between the first latch 123 and the second latch 112 in the sliding direction, thus completing the assembly. When the push rod 121 moves in the opposite direction in the first mounting hole 111 to switch to the extended state, the first stop surface 1232 and the second stop surface 1122 abut against each other, axially limiting the push rod 121.

[0061] It is easy to understand that when the telescopic member 120 is in the retracted state, the distance between the first stop surface 1232 and the second stop surface 1122 is the maximum length L2 of the telescopic member 120 extending relative to the base 110 when it is in the extended state.

[0062] Optionally, at least one of the base 110 and the telescopic member 120 may be provided with a guide groove, and the other with a guide block, the guide block slidingly engaging with the guide groove. This improves the accuracy of the telescopic member 120's linear reciprocating motion and makes the sliding smoother. Specifically, the base 110 may have a guide groove, and the telescopic member 120 may have a guide block, achieving a sliding engagement between the base 110 and the telescopic member 120. Alternatively, the base 110 may have a guide block, and the telescopic member 120 may have a guide groove, achieving a sliding engagement between the base 110 and the telescopic member 120. Alternatively, the base 110 may have both a guide groove and a guide block, and the telescopic member 120 may have both a guide groove and a guide block; the guide groove on the telescopic member 120 and the guide block on the base 110 may slide together, and the guide block on the telescopic member 120 and the guide groove on the base 110 may slide together.

[0063] It is understood that the telescopic structure 100 can have one set of sliding fit between guide grooves and guide blocks, or it can have two, three, four or more sets of sliding fit between guide grooves and guide blocks. In the structure of each set of guide grooves and guide blocks, the cross-sectional shape of the guide groove matches the cross-sectional shape of the guide block. The cross-sectional shapes of the guide grooves and guide blocks include, but are not limited to, straight lines, L-shapes, U-shapes, I-shapes, C-shapes, etc.

[0064] Optionally, the matching gap between the guide groove and the guide block is 0-0.2mm. In this way, the straightness of movement can be ensured, the guiding property is improved, and the jamming during sliding is prevented, and the sliding is smoother.

[0065] In combination Figures 6 to 8 Optionally, the telescopic member 120 comprises a first limiting part 122 connected with the push rod 121, and the first limiting part 122 extends along the axial direction of the push rod 121. The base 110 is provided with a first sliding guide part 113. The first limiting part 122 is provided with a guide groove, and the first sliding guide part 113 is provided with a guide block matched with the guide groove; and / or, the first limiting part 122 is provided with a guide block, and the first sliding guide part 113 is provided with a guide groove matched with the guide block.

[0066] In the embodiment, the guide groove comprises a first guide groove 1224, and the guide block comprises a first guide block 1131. The first limiting part 122 comprises a first rib plate 1221, a base plate 1222 and a second rib plate 1223 connected in sequence, and the first rib plate 1221 and the second rib plate 1223 are oppositely arranged; the first rib plate 1221, the base plate 1222 and the second rib plate 1223 jointly form the first guide groove 1224.

[0067] Optionally, the telescopic member 120 comprises two oppositely arranged first limiting parts 122, each of which forms a first guide groove 1224; the two first guide grooves 1224 are oppositely arranged. The first guide block 1131 is arranged between the two first guide grooves 1224. The two first guide grooves 1224 are respectively in sliding cooperation with the first guide block 1131. In the embodiment, the matching gap between the first rib plate 1221, the base plate 1222 and the second rib plate 1223 and the first guide block 1131 during sliding is 0-0.2mm.

[0068] Optionally, the extension length L1 of the first limiting part 122 is greater than or equal to the maximum length L2 of the push rod 121 extending relative to the base 110 in the extended state. The end of the first limiting part 122 away from the push rod 121 is provided with a third guide inclined surface 1225. During assembly, the third guide inclined surface 1225 plays a guiding role, facilitating insertion into the first mounting hole 111, and improving the convenience and efficiency of assembly.

[0069] Optionally, the telescopic member 120 comprises a second limiting portion 124 and a third limiting portion 125 connected with the push rod 121 respectively, and the second limiting portion 124 and the third limiting portion 125 are arranged on two sides of the push rod 121 respectively. The base 110 is provided with a second sliding guide portion 114 and a third sliding guide portion 115. At least one of the second limiting portion 124 and the third limiting portion 125 is provided with a guide groove, and at least one of the second sliding guide portion 114 and the third sliding guide portion 115 is provided with a guide block matched with the guide groove; and / or, at least one of the second limiting portion 124 and the third limiting portion 125 is provided with a guide block, and at least one of the second sliding guide portion 114 and the third sliding guide portion 115 is provided with a guide groove matched with the guide block.

[0070] In combination Figure 9 In the embodiment, the guide groove further comprises a second guide groove 1241 and a third guide groove 1151, and the guide block further comprises a second guide block 1141 and a third guide block 1251. The second limiting portion 124 is provided with the second guide groove 1241, and the second sliding guide portion 114 is provided with the second guide block 1141 matched with the second guide groove 1241 in sliding. The third limiting portion 125 is provided with the third guide block 1251, and the third sliding guide portion 115 is provided with the third guide groove 1151 matched with the third guide block 1251 in sliding.

[0071] Optionally, the second limiting portion 124 and the third limiting portion 125 are integrally formed. The second guide groove 1241 and the third guide block 1251 are respectively arranged on the upper and lower sides of the push rod 121.

[0072] The first sliding guide portion 113 and the second sliding guide portion 114 are arranged in the sliding direction. The first sliding guide portion 113 and the third sliding guide portion 115 are arranged in the sliding direction. The sliding direction is the moving direction of the push rod 121. In this way, the telescopic member 120 can be better guided and limited, especially when the telescopic member 120 is in the extended state and suspends the article, the stability is better, and the structure is more reliable.

[0073] Optionally, the interval between the first guide sliding part 113 and the second guide sliding part 114 in the moving direction of the push rod 121 is greater than or equal to the maximum length of the push rod 121 extending relative to the base 110 in the extended state. In the embodiment, the second guide sliding part 114 and the third guide sliding part 115 are integrally arranged, and the second guide block 1141 and the third guide groove 1151 are respectively located at the opposite sides of the integral structure to achieve better guiding and limiting. In other words, the interval between the first guide sliding part 113 and the third guide sliding part 115 in the moving direction of the push rod 121 is greater than or equal to the maximum length of the push rod 121 extending relative to the base 110 in the extended state. It can be understood that the distance between the first guide sliding part 113 and the second guide sliding part 114 is the distance between the two end faces facing each other. The distance between the first guide sliding part 113 and the third guide sliding part 115 is the distance between the two end faces facing each other.

[0074] In some other embodiments, only one or any two of the above-mentioned three sets of cooperating structures of guide grooves and guide blocks can be provided, which is not limited here.

[0075] Optionally, the telescopic structure 100 further comprises an elastic member 140, one end of the elastic member 140 abutting against the base 110, and the other end abutting against the telescopic member 120. When the locking member 130 and the telescopic member 120 are in the disengaged state, the telescopic member 120 slides relative to the base 110 under the action of the elastic member 140 to be in the extended state. The elastic member 140 can be a spring or a spring sheet, and in the embodiment, the elastic member 140 is a spring.

[0076] The base 110 is provided with a pin hole 116 and an abutting part 117, and the telescopic member 120 comprises a push rod 121 and a mounting pin 126 connected with the push rod 121, the mounting pin 126 being arranged in the pin hole 116. The elastic member 140 is arranged on the mounting pin 126; one end of the elastic member 140 abuts against the abutting part 117, and the other end abuts against the push rod 121. In the embodiment, the spring is sleeved on the mounting pin 126. In the retracted state, the elastic member 140 is compressed to store elastic potential energy. When the locking member 130 and the telescopic member 120 are disengaged, the elastic potential energy is released to push the push rod 121 to slide in the first mounting hole 111 to switch to the extended state.

[0077] Optionally, the mounting pin 126 extends along the axial direction of the push rod 121. The mounting pin 126 is located between the two first limiting parts 122, and the structure is more compact.

[0078] In combination with Figure 10Optionally, the locking member 130 is clamped with the base 110. When the telescopic member 120 is in the retracted state relative to the base 110, the locking member 130 is clamped with the telescopic member 120. The base 110 is provided with a second mounting hole 118, and the locking member 130 is provided with a third clamping buckle 131 with elasticity, which is clamped in the second mounting hole 118. In other embodiments, the locking member 130 and the base 110 can also be connected by bolts, insertion, adhesion, welding, riveting, magnetic adsorption or other connection methods, which are not limited here.

[0079] Optionally, the locking member 130 is clamped with the telescopic member 120, so that the telescopic member 120 is in the retracted state relative to the base 110. The locking member 130 is provided with a clamping jaw 132, and the telescopic member 120 is provided with a locking pin 127, which are clamped.

[0080] Optionally, the locking member 130 adopts a labyrinth lock. It can be understood that the locking pin 127 and the push rod 121 are fixedly connected or integrally arranged. When the push rod 121 is moved in the sliding first direction under the action of external force, the locking pin 127 moves together until the locking pin 127 is inserted into the clamping jaw 132. The clamping jaw 132 is provided with a barb, so as to realize the locking of the clamping jaw 132 and the locking pin 127. At this time, the push rod 121 is in the retracted state. When the push rod 121 is pressed again by the external force in the first direction, the locking pin 127 pushes the clamping jaw 132, the clamping jaw 132 is unlocked, and the clamping jaw 132 and the locking pin 127 are disengaged. At this time, the push rod 121 slides in the second direction under the action of the elastic member 140, and switches to the extended state.

[0087] During installation, the telescopic member 120 is first connected to the base 110, and then the decorative cover 150 is connected to the base 110. Figure 3Taking the shown perspective as an example, the maze lock is engaged with the second mounting hole 118 of the base 110. An elastic element 140 is sleeved on the mounting pin 126, which extends into the pin hole 116. One end of the elastic element 140 abuts against the supporting part 117. The first guide slide 113 slides in cooperation with the first limiting part 122, the second guide slide 114 and the second limiting part 124, the third guide slide 115 and the third limiting part 125, respectively. An external force in a first direction is applied to the end of the push rod 121 away from the mounting pin 126, pushing the push rod 121 so that it extends into the first mounting hole 111. During the movement of the push rod 121, the first latch 123 presses against the second latch 112 and passes over it. After the first latch 123 passes over the second latch 112, the second latch 112 returns to its original shape. The push rod 121 continues to move under the action of external force, and the elastic element 140 is compressed until the locking pin 127 and the labyrinth lock are engaged, and the assembly is completed.

[0088] After assembly, the push rod 121 of the telescopic structure 100 is in the retracted state relative to the base 110. To switch from the retracted state to the extended state, an external force is applied to press the push rod 121 along the first direction. The locking pin 127 pushes the labyrinth lock's pawl 132, causing the pawl 132 to open and separate from the locking pin 127. The push rod 121 then slides along the second direction under the action of the elastic element 140 until the first latch 123 and the second latch 112 abut against each other, at which point the push rod 121 is in the extended state relative to the base 110. The second direction is opposite to the first direction.

[0089] If it is necessary to switch from the extended state to the retracted state, an external force is applied to press the push rod 121 in the first direction. The first latch 123 moves away from the second latch 112, and the elastic element 140 is compressed until the locking pin 127 engages with the claw 132 of the labyrinth lock. The push rod 121 is in the retracted state relative to the base 110.
