Description

Technical Field

[0001] This invention relates to the field of vehicle mount technology, and in particular to a multi-joint linkage vehicle mount. Background Technology

[0002] With the growing demand for in-vehicle navigation, multimedia entertainment, and mobile office applications, in-vehicle mounts that secure smartphones, tablets, and other mobile devices inside vehicles for easy viewing and operation by drivers or passengers have become commonplace. To accommodate different vehicle interior layouts and users' personalized viewing angle needs, mount structures with multi-degree-of-freedom adjustment capabilities are widely adopted.

[0003] Most multi-degree-of-freedom vehicle mounts on the market currently employ a robotic arm structure composed of multiple independent joints connected in series. Each joint typically includes a rotating or ball-joint connection component and is equipped with an independent locking mechanism, such as a knob, wrench, or screw. When a user needs to adjust the posture of the mobile terminal, they must loosen the independent locking mechanism of each joint one by one, and then relock each joint one by one after the adjustment is in place. This operation method is cumbersome and time-consuming, especially inconvenient for quick one-handed adjustments while driving, and it is easy to miss locking a joint, causing the terminal device to shake or tip over during vehicle bumps, posing a safety hazard. Summary of the Invention

[0004] The main objective of this invention is to propose a multi-joint linkage vehicle mount, which aims to solve the technical problem of inconvenient adjustment of multi-degree-of-freedom vehicle mounts in the prior art.

[0005] To achieve the first objective, the multi-joint linkage vehicle mount proposed in this invention includes a pin fixing assembly, a mounting component, two arm assemblies, and an adjustment assembly. The pin fixing assembly is used to connect to the vehicle's interior trim panel; the mounting component is used to mount a mobile terminal; each arm assembly includes a swing arm, a push rod, a ball head, and a ball sleeve. One end of the swing arm is connected to the ball sleeve, and the swing arm is hollow. The push rod is slidably installed inside the swing arm, with a sliding end and an abutting end at opposite ends. The abutting end abuts against the ball head, and the ball head is hinged inside the ball sleeve. The push rod can slide relative to the swing arm and cause the ball head to abut against or loosen against the ball sleeve. The ball head in one arm assembly is connected to the pin fixing assembly, and the ball head in the other arm assembly is connected to the mounting component. The adjustment assembly includes a knob, an adjustment rod, an adjustment component, two adjustment shells, and two top blocks. The two swing arms are respectively connected to the two adjusting shells, which are respectively covered by the two top blocks. Each top block has an inclined surface. The sliding end of each top rod extends into the corresponding adjusting shell and slides in cooperation with the inclined surface. The adjusting rod passes through the two top blocks, and its two ends extend out of the two adjusting shells respectively. The two ends of the adjusting rod are respectively connected to the knob and the adjusting member. The knob can move along the adjusting rod towards the adjusting member, so that the knob and the adjusting member abut against the two top blocks respectively, thereby pushing the two top blocks closer to each other. When the two top blocks are closer to each other, they can drive the two adjusting shells closer to each other until they are pressed together. When each top block moves towards the other top block, each top block can push the corresponding top rod to slide radially along the adjusting rod through the inclined surface, thereby driving the ball head to abut against the ball sleeve through the top rod.

[0006] In one embodiment, the adjusting rod is a threaded rod with an external thread engraved on its wall. The adjusting element is a nut. The knob has a turning groove, and the inner wall of the turning groove has an internal thread that meshes with the external thread. The two ends of the threaded rod pass through the turning groove and the threaded hole of the nut, respectively. When the knob is rotated, it can move relative to the threaded rod towards or away from the nut, so as to cooperate with the nut to push the two top blocks closer to or further away from each other.

[0007] In one embodiment, the adjusting assembly further includes a spring, which is sleeved on the adjusting rod and has its two ends abutting against the two adjusting shells respectively.

[0008] In one embodiment, the side of each adjustment shell facing the other adjustment shell is a snap-fit ​​surface. One of the snap-fit ​​surfaces is provided with a plurality of snap teeth, and the other snap-fit ​​surface is provided with a plurality of snap slots. The plurality of snap teeth and the plurality of snap slots are the same in number and are arranged in a one-to-one correspondence. When the two adjustment shells approach each other until they are pressed together, each snap tooth engages with the corresponding snap slot.

[0009] In one embodiment, the interior trim panel of the vehicle has a connecting hole. The pin fixing assembly includes a support, a plug rod, and a connector. The support has a plug hole and a through hole. The plug hole and the through hole are in different directions but are interconnected. One end of the plug rod is connected to the corresponding ball head, and the other end of the plug rod has a through hole. The end of the plug rod with the through hole is inserted into the plug hole. The connector passes through the through hole and the through hole and can extend into the connecting hole to connect with the interior trim panel, so as to fix the vehicle bracket to the interior trim panel.

[0010] In one embodiment, the support includes an interconnected insertion section and a positioning section, the positioning section being located on the side of the insertion section near the interior panel, the through hole penetrating the insertion section and the positioning section, the positioning section being able to be inserted into the connection hole, and the connector being able to pass through the insertion section and the positioning section in sequence and then extend into the connection hole to connect with the interior panel.

[0011] In one embodiment, the pin fixing assembly further includes an elastic washer, which is sleeved outside the support. The elastic washer has a contact surface that is angled to the extension direction of the through hole, and the contact surface can abut against the interior panel when the positioning section is inserted into the connecting hole.

[0012] In one embodiment, a weakening groove is formed on the wall of the plug rod, and the weakening groove is located outside the plug hole.

[0013] In one embodiment, the mounting element is a magnetic chuck, a clamp, a screw, or a ball joint.

[0014] In one embodiment, the multi-joint linkage vehicle mount further includes an elastic buckle, which is snapped onto any one of the swing arms, and the elastic buckle has a cable pass-through groove.

[0015] The multi-joint linkage vehicle mount proposed in this invention connects the mounting component to the pin fixing component via an adjustment assembly and two arm segments. The adjustment assembly allows the two arm segments to rotate relative to each other, and each arm segment can rotate relative to the pin fixing component or the mounting component, thereby achieving multi-joint adjustment between the pin fixing component and the mounting component. When a mobile terminal is mounted on the mounting component, the position and angle of the mobile terminal relative to the vehicle interior panel can be adjusted. A knob drives the adjustment rod to rotate, which in turn moves two top blocks relative to each other. These top blocks, through two top rods, engage or disengage two ball heads from their corresponding ball sleeves. Simultaneously, the two adjustment shells engage or disengage from each other. Therefore, simply turning the knob allows for locking or unlocking between the two arm segments, between the arm segments and the pin fixing component, and between the arm segments and the mounting component. This enables the driver to perform multi-joint linkage adjustment with one hand, significantly improving the convenience and efficiency of vehicle mount attitude adjustment and locking, and enhancing driver safety during driving.

[0030] Most multi-degree-of-freedom vehicle mounts on the market currently employ a robotic arm structure composed of multiple independent joints connected in series. Each joint typically includes a rotating or ball-joint connection component and is equipped with an independent locking mechanism, such as a knob, wrench, or screw. When a user needs to adjust the posture of the mobile terminal, they must loosen the independent locking mechanism of each joint one by one, and then relock each joint one by one after the adjustment is in place. This operation method is cumbersome and time-consuming, especially inconvenient for quick one-handed adjustments while driving, and it is easy to miss locking a joint, causing the terminal device to shake or tip over during vehicle bumps, posing a safety hazard.

[0031] This invention proposes a multi-joint linkage vehicle mount, comprising a pin fixing assembly 10, a mounting component 20, two arm segments assemblies 30, and an adjusting assembly 40. The pin fixing assembly 10 is used to connect to the vehicle's interior trim panel; the mounting component 20 is used to mount a mobile terminal; each arm segment assembly 30 includes a swing arm 31, a push rod 32, a ball head 33, and a ball sleeve 34. One end of the swing arm 31 is connected to the ball sleeve 34, and the swing arm 31 is hollow. The push rod 32 is slidably installed inside the swing arm 31. The two ends are a sliding end 321 and an abutting end 322, respectively. The abutting end 322 abuts against the ball head 33, which is hinged inside the ball sleeve 34. The push rod 32 can slide relative to the swing arm 31 and drive the ball head 33 to abut against or release the ball sleeve 34. The ball head 33 in one arm segment assembly 30 is connected to the pin fixing assembly 10, and the ball head 33 in the other arm segment assembly 30 is connected to the mounting part 20. The adjustment assembly 40 includes a knob 41, an adjustment rod 42, an adjustment part 45, and two adjustment shells. 43 and two top blocks 44, two swing arms 31 are respectively connected to two adjusting shells 43, the two adjusting shells 43 are respectively covered outside the two top blocks 44, each top block 44 has an inclined surface 441, the sliding end 321 of each top rod 32 extends into the corresponding adjusting shell 43 and slides in cooperation with the inclined surface 441, the adjusting rod 42 passes through the two top blocks 44, the two ends of the adjusting rod 42 extend out of the two adjusting shells 43 respectively, and the two ends of the adjusting rod 42 are respectively connected to the knob 41 and the adjusting component 45; the knob 41 can move along the adjusting rod 42 toward the adjusting member 45, so that the knob 41 and the adjusting member 45 respectively abut against the two top blocks 44, so as to push the two top blocks 44 closer to each other. When the two top blocks 44 are close to each other, they can drive the two adjusting shells 43 to be close to each other until they are pressed together. When each top block 44 moves toward the other top block 44, each top block 44 can push the corresponding top rod 32 to slide radially along the adjusting rod 42 through the inclined surface 441, so as to drive the ball head 33 to be pressed against the ball sleeve 34 through the top rod 32.

[0032] Please see Figures 1 to 4The multi-joint linkage vehicle mount is fixed to the vehicle's interior panel via a pin fixing assembly 10, and a mobile terminal is mounted via an mounting piece 20, thereby mounting mobile terminals such as mobile phones and tablets inside the vehicle. The pin fixing assembly 10 is connected to the adjustment assembly 40 via an arm joint assembly 30, and the mounting piece 20 is connected to the adjustment assembly 40 via another arm joint assembly 30. In each arm segment assembly 30, a ball head 33 is hinged within a ball sleeve 34. The end of the ball sleeve 34 furthest from the push rod 32 has a slot. The ball head 33 passes through the slot and connects to the pin fixing assembly 10 or the mounting component 20. This hinged connection between the ball head 33 and the ball sleeve 34 allows for multi-angle connections between the pin fixing assembly 10 or the mounting component 20 and the arm segment assembly 30. One end of the swing arm 31 is connected to the ball sleeve 34, and the end of the push rod 32 on this side is the abutment end 322. The other end of the swing arm 31 is connected to the corresponding adjusting housing 43, and the end of the push rod 32 on this side is the sliding end 321. The extension direction of the swing arm 31 is perpendicular to the axial direction of the adjusting rod 42. It should be noted that the axial direction of the adjusting rod 42 is... Figure 1 and Figure 2 The first direction in the middle, Figure 1 and Figure 2 The second and third directions are both radial directions of the adjusting rod 42, that is, the two swing arms 31 respectively move along... Figure 1 and Figure 2The adjustment housings 43 extend in the second and third directions. Two adjustment housings 43 are arranged side-by-side along the axial direction of the adjustment rod 42, and the two adjustment housings 43 can rotate relative to each other along the axial direction of the adjustment rod 42 to adjust the relative angle of the two arm segment assemblies 30, thereby adjusting the position and angle of the mobile terminal in the vehicle. Each adjustment housing 43 has a corresponding top block 44, and the sliding end 321 of each top rod 32 extends into the adjustment housing 43 and slides in cooperation with the inclined surface 441 of the top block 44. The adjustment rod 42 passes through the two top blocks 44 in sequence and extends out of the adjustment housing 43 before connecting to the knob 41. When the knob 41 is turned, the knob 41 rotates relative to the adjustment rod 42, and the turning action moves relative to the adjustment rod 42. When the knob 41 moves toward the adjusting member 45, the knob 41 and the adjusting rod 42 press against the two top blocks 44 from both sides, squeezing the two top blocks 44 to move toward each other. At this time, the two inclined surfaces 441 can push the corresponding top rods 32 to slide in the corresponding swing arms 31, so that the abutting ends 322 of each swing arm 31 press against the corresponding ball head 33 and ball sleeve 34, thereby preventing the relative rotation of each arm segment assembly 30 with the pin fixing assembly 10 or the mounting member 20. At the same time, when each top block 44 moves, it can drive the adjusting shell 43 sleeved on it to move together. When the two top blocks 44 move toward each other, they can drive the two adjusting shells 43 to move toward each other until the two adjusting shells 43 press against each other, thereby preventing the relative rotation between the two arm segment assemblies 30. Similarly, when the two top blocks 44 move away from each other, each inclined surface 441 disengages from the corresponding sliding end 321, causing the abutting end 322 to disengage from the corresponding ball head 33, so that the ball head 33 can rotate relative to the ball sleeve 34, thereby allowing each arm segment assembly 30 to rotate relative to the pin fixing assembly 10 or the mounting part 20. At the same time, the two top blocks 44 move away from each other, so as to drive the two adjusting shells 43 to disengage from each other, thereby allowing the two arm segment assemblies 30 to rotate relative to each other.

[0033] The multi-joint linkage vehicle mount proposed in this invention has a mounting component 20 connected to a pin fixing component 10 via an adjustment component 40 and two arm segments 30. The adjustment component 40 allows the two arm segments 30 to rotate relative to each other, and each arm segment 30 can rotate relative to the pin fixing component 10 or the mounting component 20, thereby realizing a multi-joint setup between the pin fixing component 10 and the mounting component 20. When a mobile terminal is mounted on the mounting component 20, the posture adjustment of the mobile terminal relative to the vehicle interior panel in terms of its position and angle is possible. By rotating the knob 41 relative to the adjusting rod 42, the knob 41 and the adjusting component 45 work together to press or release the two top blocks 44, causing the two top blocks 44 to move closer or further apart. The two top blocks 44, through the two top rods 32, respectively, press or release the two ball heads 33 from the corresponding ball sleeves 34. At the same time, the two adjusting shells 43 press or release from each other. Thus, by simply turning the knob 41, the two arm sections 30 can be locked or unlocked together, the arm section 30 and the pin fixing component 10 can be locked or unlocked together, allowing the driver to complete the linkage adjustment of multiple joints with one hand. This significantly improves the convenience and efficiency of the vehicle bracket posture adjustment and locking operation, and enhances the driver's safety during driving.

[0034] In one embodiment, the adjusting rod 42 is a threaded rod with an external thread 421 engraved on its wall. The adjusting element 45 is a nut. The knob 41 has a turning groove 411, and the inner wall of the turning groove 411 is provided with an internal thread that meshes with the external thread 421. The two ends of the threaded rod pass through the turning groove 411 and the screw hole of the nut, respectively. When the knob 41 is rotated, it can move relative to the threaded rod towards or away from the nut, so as to cooperate with the nut to push the two top blocks 44 towards or away from each other.

[0035] It should be noted that the knob 41 and the nut are located on opposite sides of the two adjusting shells 43. The two ends of the threaded rod pass through the screw groove 411 of the knob 41 and the threaded hole of the nut, respectively. The external thread 421 of the threaded rod simultaneously connects with the internal threads of both the knob 41 and the nut, forming a threaded pair. When the knob 41 is rotated, the internal thread of the knob 41 and the external thread 421 of the threaded rod undergo helical transmission, causing the knob 41 to move axially along the axis of the threaded rod, moving closer to or away from the nut. When the knob 41 moves closer to the nut, the end face of the knob 41 and the end face of the nut respectively contact the two top blocks 44 from both sides. Applying opposing axial compressive forces pushes the two top blocks 44 closer together along the axial direction of the threaded rod. The axial movement is then converted into radial sliding of the top rod 32 via the inclined surface 441 of the top blocks 44, ultimately achieving the clamping of the ball head 33 and the ball sleeve 34, and the mutual locking of the two adjusting shells 43. Conversely, when the knob 41 rotates away from the nut, the axial constraint of the knob 41 and nut on the two top blocks 44 is relaxed, and the two top blocks 44 gain a gap for opposite movement. The sliding end 321 of the top rod 32 can then retract along the inclined surface 441, releasing the pressure on the ball head 33. Simultaneously, the two adjusting shells 43 can also rotate relative to each other. The threaded transmission mechanism consisting of the knob 41, the threaded rod, and the nut has a self-locking characteristic. When the knob 41 is not manually rotated, the top blocks 44, the top rod 32, and the adjusting shells 43 can be locked in their current positions, ensuring the durability and reliability of the locked state of each joint after adjustment, and preventing accidental loosening due to vehicle vibration.

[0036] In one embodiment, the adjusting assembly 40 further includes a spring 46, which is sleeved on the adjusting rod 42 and has its two ends abutting against the two adjusting shells 43 respectively.

[0037] It can be explained that the two ends of the spring 46 abut against the two adjusting shells 43 respectively; so that when the spring 46 is compressed, it always applies an elastic force to the two adjusting shells 43, causing them to move away from each other along the axial direction of the adjusting rod 42. When the knob 41 is loosened and the axial compression of the knob 41 and nut on the two top blocks 44 is relaxed, the elastic potential stored in the spring 46 can be released. Its two ends push the two adjusting shells 43 that are abutting each other, causing the two adjusting shells 43 to move away from each other along the axial direction of the adjusting rod 42. The mutual separation of the two adjusting shells 43 directly causes the two top blocks 44 contained inside to move away from each other synchronously. The inclined surface 441 on each top block 44 then slides relative to the sliding end 321 of the corresponding top rod 32. The top rod 32 retracts along the inner cavity of the swing arm 31 in the direction that makes its abutting end 322 move away from the ball head 33, thereby releasing the pressing force of the abutting end 322 on the ball head 33, allowing the ball head 33 to return to a free hinged state within the ball sleeve 34. At the same time, the two adjusting shells 43 move away from each other to a certain distance, providing a physical gap for the relative rotation between the two adjusting shells 43, allowing the user to manually adjust the relative angle of the two arm section assemblies 30.

[0038] In one embodiment, the side of each adjustment shell 43 facing the other adjustment shell 43 is a snap-fit ​​surface. One snap-fit ​​surface is provided with a plurality of snap teeth 431, and the other snap-fit ​​surface is provided with a plurality of snap grooves 432. The plurality of snap teeth 431 and the plurality of snap grooves 432 are the same in number and are provided in a one-to-one correspondence. When the two adjustment shells 43 approach each other until they are pressed together, each snap tooth 431 engages with the corresponding snap groove 432.

[0039] Please see Figure 1 When the two adjusting shells 43 approach each other, the two engaging surfaces abut against each other, and each locking tooth 431 can be precisely embedded in its corresponding slot 432. Through the one-to-one meshing relationship, precise angular positioning is achieved, providing multiple locking positions for the relative rotation between the two boom assemblies 30. The engaging cooperation between the locking tooth 431 and the slot 432 directly converts the circumferential force that may exist between the two adjusting shells 43 into surface contact and compression between the side of the locking tooth 431 and the side wall of the slot 432, significantly increasing the friction area and structural strength to resist relative rotation. This effectively suppresses the micro-movement or slippage of the two adjusting shells 43 in the locked state, and achieves the tight locking of the two adjusting shells 43.

[0040] In one embodiment, the interior trim panel of the vehicle has a connection hole. The pin fixing assembly 10 includes a support 11, a plug rod 12, and a connector 13. The support 11 has a plug hole 111 and a through hole 112. The plug hole 111 and the through hole 112 are in different directions and are interconnected. One end of the plug rod 12 is connected to the corresponding ball head 33. The other end of the plug rod 12 has a through hole 121. The end of the plug rod 12 with the through hole 121 is inserted into the plug hole 111. The connector 13 passes through the through hole 112 and the through hole 121 and can extend into the connection hole to connect with the interior trim panel, so as to fix the vehicle bracket to the interior trim panel.

[0041] Please see Figure 5 The vehicle's interior trim panel has multiple connection holes, which provide standardized installation interfaces for the bracket. The support 11 has insertion holes 111 and through holes 112 with different directions, allowing the installation path of the insertion rod 12 and the locking path of the connector 13 to be spatially staggered and separated. This arrangement allows for the independent connection of the insertion rod 12 to the ball head 33 and the support 11, followed by the separate installation and locking of the connector 13, simplifying the installation process and avoiding interference between components. One end of the insertion rod 12 connects to the ball head 33, while the other end has a through hole 121 for insertion. The insertion hole 111 enables a movable connection between the arm assembly 30 and the fixed support 11, and also provides a stable alignment base for the subsequent insertion of the connector 13 through the insertion fit. The connector 13 passes through the through hole 112 of the support 11, the through hole 121 of the insertion rod 12, and finally extends into the connection hole of the interior panel. This method achieves a series rigid connection between the support 11, the insertion rod 12, and the interior panel through a single fastener, directly transferring the load on the multi-joint linkage vehicle bracket to the vehicle interior panel structure, with concentrated fastening force and a clear path. The structure of the pin fixing assembly 10, through the spatial separation design of the insertion hole 111 and the through hole 112, realizes the step-by-step operation of the installation process and the unified final locking state, ensuring the stability and load-bearing strength of the connection between the bracket and the vehicle.

[0042] In one embodiment, the support 11 includes an interlocking section 113 and a positioning section 114 connected to each other. The positioning section 114 is located on the side of the interlocking section 113 near the interior panel. A through hole 112 passes through the interlocking section 113 and the positioning section 114. The positioning section 114 can be interlocked with the connecting hole. The connector 13 can pass through the interlocking section 113 and the positioning section 114 in sequence and then extend into the connecting hole to connect with the interior panel.

[0043] Furthermore, the positioning section 114 is located on the side of the insertion section 113 closest to the interior panel, allowing the positioning section 114 to extend towards the connection hole first during installation of the support 11, naturally forming an installation guide and simplifying the alignment process. The through hole 112 passes through both the insertion section 113 and the positioning section 114, forming a continuous and coaxial channel, ensuring the straightness and smoothness of the path of the connector 13, avoiding installation resistance caused by the deviation of the segmented hole positions, and at the same time, enabling the insertion section 113 and the positioning section 114 to combine into an integral load-bearing structure after the connector 13 passes through, improving the structural integrity of the support 11 under stress. The insertion and engagement of the positioning section 114 with the connecting hole enables the initial positioning and circumferential constraint of the support 11 before the connector 13 is locked, effectively preventing the support 11 from sliding or deflecting before final tightening, thus ensuring the accuracy of the installation position. The connector 13 passes through the through hole 112 of the insertion section 113 and the through hole 112 of the positioning section 114 in sequence and finally extends into the connecting hole of the interior panel for locking, so that the torque and vibration borne by the multi-joint linkage vehicle bracket are directly transmitted to the interior panel through the positioning section 114, and the connection between the insertion section 113 and the positioning section 114 is used to disperse local stress.

[0044] In one embodiment, the pin fixing assembly 10 further includes an elastic washer 14, which is sleeved on the support 11. The elastic washer 14 has an abutment surface 141 that is distributed at an angle to the extension direction of the through hole 112. The abutment surface 141 can abut against the interior panel when the positioning section 114 is inserted into the connection hole.

[0045] Furthermore, the elastic gasket 14 is placed between the support 11 and the vehicle's interior panel. The abutment surface 141 and the extension direction of the through hole 112 are distributed at an angle, so that when the positioning section 114 is inserted into the connection hole, the abutment surface 141 of the elastic gasket 14 abuts against the vehicle's interior panel, thereby restricting the support 11 from rotating radially relative to the interior panel along the connector 13, which facilitates the installation and fixing of the connector 13. When the pin fixing assembly 10 is connected to the interior panel, the abutment surface 141 continues to abut against the interior panel, forming an adaptive deformation elastic interface between the support 11 and the interior panel. This not only effectively disperses the local stress at the connection point and reduces the risk of loosening of the connection due to long-term vibration, but also improves the overall stability and noise reduction effect of the multi-joint linkage vehicle bracket after installation by filling the gap and absorbing micro-deformation, and protects the surface of the vehicle's interior panel from pressure damage or scratches caused by hard contact.

[0046] In one embodiment, a weakening groove 122 is provided on the rod wall of the plug rod 12, and the weakening groove 122 is located outside the plug hole 111.

[0047] It should be noted that the cross-sectional dimension of the plug rod 12 located at the weakening groove 122 is smaller than that at other locations. When the bracket is subjected to abnormal external force or impact load, the weakening groove 122 becomes a stress concentration area due to the weakened cross-section, which can preferentially undergo controllable elastic deformation or fracture, thereby dissipating and absorbing excess energy and preventing the multi-joint linkage vehicle bracket from breaking or falling off as a whole and causing large-scale secondary damage.

[0048] In one embodiment, the mounting component 20 is a magnetic chuck 21, a clamp 22, a screw, or a ball joint 23.

[0049] Please see Figure 1 , Figure 6 and Figure 7 The mounting component 20 can be any one of the magnetic chuck 21, clamp 22, screw or ball joint interface 23 in the prior art, providing multiple options for fixing the mobile terminal. It can select the most suitable installation method according to the specific characteristics and usage scenarios of the mobile terminal, thereby significantly improving the applicability and flexibility of the multi-joint linkage vehicle mount while ensuring connection reliability.

[0050] In one embodiment, the multi-joint linkage vehicle mount further includes an elastic buckle 50, which is snapped onto any one of the swing arms 31, and the elastic buckle 50 has a cable groove 51 for cables to pass through.

[0051] Understandably, the elastic buckle 50 can be snapped onto the outside of the swing arm 31, and its position can be flexibly adjusted according to the cable routing requirements. The elastic buckle 50 has a cable slot 51, which facilitates the orderly arrangement of the mobile terminal's cable. Two rows of blocking teeth are provided on both sides of the slot opening of the cable slot 51. These two rows of blocking teeth can block the slot opening, thereby preventing the cable from coming out of the cable slot 51. The elastic buckle 50 is made of elastic material. By applying external force to both sides of the slot opening of the cable slot 51, the two rows of blocking teeth are moved away from each other, thereby allowing the cable to be removed from the cable slot 51. When the external force is removed, the slot opening of the cable slot 51 can be reset under the elastic action.

[0052] The first embodiment is merely an exemplary implementation of the present invention and is not intended to limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention, the description and drawings of the present invention, or direct / indirect applications in other related technical fields are included within the scope of protection of the present invention.
