Description

Technical Field

[0002] In recent years, driven by the rapid development of artificial intelligence (AI), autonomous driving has become a future trend. Relying on the collaborative efforts of AI, visual computing, radar, monitoring devices, and global satellite navigation systems, autonomous vehicles can be safely and autonomously operated by computers without any human intervention. Vehicle positioning primarily relies on GPS products, and the functions of in-vehicle location and orientation systems generally include SMS positioning, scheduled positioning, network query, remote monitoring, and remote locking.

[0003] In the prior art, due to the increase in the functions of the vehicle locator, the vehicle locator will have many socket settings, and the sockets need to be connected to the signal transmission cable. However, the socket and plug installation of the vehicle locator are easily subjected to vibration transmission during the driving of the car, thereby colliding with other parts of the car. The relative displacement between the cable plug and the socket of the vehicle locator also causes the pins inside the socket to bend and break, resulting in poor contact. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 12 : A vehicle-mounted positioning and orientation instrument includes a GPS body 1 and a shell 2 for placing the GPS body 1 and installed on the vehicle body. The top of the shell 2 is covered by a cover 3. The splicing sides of the shell 2 and the cover 3 are both provided with a wire sleeve 2a. The wire sleeve 2a is provided with a wire groove 2a1 for placing the cable connected to the GPS body 1. The wire groove 2a1 is provided with a number of elastic balls 2a2 for fitting the outer wall of the cable; two parallel horizontally extending guide slides 2b are provided in the shell 2, and the axis of the guide slide 2b is parallel to the axis of the wire groove 2a1. A mounting seat 4 for fixedly mounting the GPS body 1 is slidably installed on the guide slide 2b, and each wire sleeve 2a is provided with two first springs 2c. The first springs 2c are respectively located at both ends of the mounting seat 4 and elastically connect the inner wall of the shell 2 and the mounting seat 4. A lock 4a is provided at the bottom of the mounting seat 4. The lock 4a locks the mounting seat 4 on the guide slide 2b when the cover 3 and the shell 2 are assembled.

[0034] When using this application, the staff first opens the cover 3 on the shell 2, fixes the GPS body 1 on the mounting seat 4, and passes the cable connecting the GPS body 1 through the wire groove 2a1 of the wire sleeve 2a on the spliced ​​side of the shell 2 and the cover 3, and the elastic ball 2a2 fits the outer wall of the cable. The shell 2 is then installed on the car body and the cover 3 is put on. At this time, the lock 4a releases the lock on the mounting seat 4, and the mounting seat 4 can slide on the guide slide 2b. When the car vibrates during driving, the mounting seat 4 slides along the guide slide 2b accordingly. At this time, the first springs 2c at both ends can absorb the vibration energy and reduce the impact of the vibration on the GPS body 1. At the same time, the elastic ball 2a2 in the wire groove 2a1 rolls with the cable vibration, and the cable shaking is offset by elastic deformation and rolling friction, so that the cable can move with the GPS body 1, avoiding loosening at the interface between the cable and the GPS body 1. During maintenance, the cover 3 is opened and the lock 4a at the bottom of the mounting seat 4 locks the mounting seat 4 in place on the guide slide 2b, making it convenient for installing and removing the GPS body 1 and for directly plugging and unplugging the cable on the GPS body 1 along the axis of the cable groove 2a1. In this embodiment, the mounting seat 4 is combined with the guide slide 2b, the first spring 2c, and the lock 4a, so that the mounting seat 4 has dual working states of elastic buffering and rigid positioning. The elastic ball 2a2 cooperates with the cable to roll and elastically deform to offset the shaking caused by vibration. This can reduce vibration transmission during vehicle operation, reduce rigid collisions at the interface between the cable and the GPS body 1, significantly prevent loose connections, and extend the service life of the device.

[0035] In order to achieve the purpose of enabling the locker 4a to switch the locking and moving states of the mounting seat 4 on the guide slide 2b, the following features are specifically provided: The bottom of the mounting seat 4 is provided with two first guide sleeves 4b which are respectively in the same straight line as the guide slide 2b, and the first guide sleeves 4b are sleeved on the guide slide 2b. The two first guide sleeves 4b are provided with a socket 4b1 on the opposite side, and a tooth groove 2b1 is provided on the side of the guide slide 2b facing the socket 4b1. The tooth grooves 2b1 are evenly spaced along the length direction of the guide slide 2b, and the cross-section of the tooth groove 2b1 is rectangular; the locker 4a includes two locking plugs 4a1 slidably mounted on the bottom of the mounting seat 4 and moving horizontally along the radial direction of the first guide sleeve 4b, the locking plugs 4a1 have the same shape as the socket 4b1, and the two locking plugs 4a1 are provided with a latching tooth 4a2 parallel to the tooth groove 2b1 on the side facing the first guide sleeve 4b. When the locking plug 4a1 is inserted into the socket 4b1 and the latching tooth 4a2 engages with the tooth groove 2b1, the position of the locker 4a on the guide slide 2b is locked.

[0036] In this embodiment, the mounting base 4 is mounted on the guide rod 2b via a first guide sleeve 4b at the bottom. The socket 4b1 on the first guide sleeve 4b is aligned with the tooth groove 2b1 on the guide rod 2b. When the housing 2 and cover 3 are separated, the locking plug 4a1 of the lock 4a slides horizontally along the radial direction of the first guide sleeve 4b and inserts into the socket 4b1. Its latching teeth 4a2 precisely engage with the tooth groove 2b1. Due to the rectangular cross-section of the tooth groove 2b1, the mounting base 4 is restricted from moving along the axis of the guide rod 2b, locking the mounting base 4 to the guide rod 2b. This secures the GPS body 1 in place and facilitates cable insertion and removal. When the housing 2 and cover 3 are assembled, the locking plug 4a1 is withdrawn from the socket 4b1, disengaging the latching teeth 4a2 from the tooth groove 2b1, releasing the lock on the mounting base 4. At this point, the mounting base 4 can slide freely on the guide rod 2b via the first guide sleeve 4b, achieving a resilient shock-absorbing effect.

[0037] In order to ensure that the movement path of the locking plug 4a1 is stable and maintains precise alignment with the socket 4b1, the following features are specifically set: A second guide sleeve 4c is provided at the bottom of the mounting seat 4, and the axis of the second guide sleeve 4c is arranged horizontally and perpendicular to the axis of the first guide sleeve 4b. A shaft 4a3 is provided on the side of the locking plug 4a1 away from the latch tooth 4a2 and is on the same axis as the second guide sleeve 4c. The shaft 4a3 is inserted into the second guide sleeve 4c through a coaxially arranged limit head 4a4. The diameter of the limit head 4a4 is the same as the inner diameter of the second guide sleeve 4c. The inner wall of the second guide sleeve 4c is provided with a limit strip 4c1 extending along the axis of the second guide sleeve 4c, and the outer wall of the limit head 4a4 is provided with a limit groove 4a5 matching the limit strip 4c1.

[0038] In this embodiment, the shaft 4a3 on the side of the locking plug 4a1 away from the latching teeth 4a2 drives the limiting head 4a4 to slide within the second guide sleeve 4c, thereby ensuring a stable movement path for the locking plug 4a1 and ensuring that the locking plug 4a1 is always aligned with the insertion hole 4b1. Due to the mutual cooperation of the limiting groove 4a5 on the outer wall of the limiting head 4a4 and the limiting clamping strip 4c1 on the inner wall of the second guide sleeve 4c, the limiting head 4a4 cannot rotate about the axis of the shaft 4a3 when moving along the axis of the second guide sleeve 4c, thereby ensuring that the locking plug 4a1 can be accurately inserted into the insertion hole 4b1.

[0039] In order to achieve the purpose of automatically changing the locking state of the locker 4a on the mounting base 4 when the cover 3 and the housing 2 are spliced ​​and separated, the following features are specifically provided: Each locking plug 4a1 is connected to the adjustment seat 4d at the bottom of the shell 2 through a vertically extending connecting block 4a6. The two adjusting seats 4d are slidably installed at the bottom of the shell 2 and move horizontally along the radial direction of the guide slide bar 2b. The two adjusting seats 4d are elastically connected by a number of connecting springs 4d1. The elastic force of the connecting spring 4d1 causes the two adjusting seats 4d to move away from each other and drives the locking plug 4a1 to fit the guide slide bar 2b; a horizontal extended bottom plate 4d2 is provided at the bottom of the adjusting seat 4d, and the extended bottom plate 4d2 extends to both sides of the mounting seat 4. A limiting inclined block 4d3 is provided at one end of the extended bottom plate 4d2 away from the adjusting seat 4d. A lower top plate 3a extending vertically downward is provided inside the cover body 3. When the cover body 3 is spliced ​​with the shell 2, the lower top plate 3a presses the inclined surface of the top of the limiting inclined block 4d3 to make the two adjusting seats 4d compress the connecting spring 4d1 and move closer to each other.

[0040] In this embodiment, the locking plug 4a1 is connected to the adjustment seat 4d via a connecting block 4a6. In its natural state, the elastic force of the connecting spring 4d1 forces the two adjustment seats 4d apart from each other. The connecting block 4a6 then drives the locking plug 4a1 against the guide slide 2b, allowing the locking plug 4a1 to be inserted into the socket 4b1 of the first guide sleeve 4b. The latching teeth 4a2 engage the tooth grooves 2b1 on the guide slide 2b, locking the mounting seat 4 and facilitating the installation and connection of the GPS body 1 and the cable. When the cover 3 is assembled with the housing 2, as the cover 3 gradually approaches the housing 2, the vertically downwardly extending lower top plate 3a within the cover 3 gradually approaches the retaining bevel 4d3 at the bottom of the adjustment seat 4d. When the lower top plate 3a contacts the inclined surface at the top of the retaining bevel 4d3, it exerts downward pressure on the retaining bevel 4d3. This pressure is then split along the inclined surface to produce a force component that pulls the two adjustment seats 4d closer together, thereby compressing the connecting spring 4d1. As the two adjustment seats 4d move horizontally toward each other, the connecting block 4a6 drives the locking plug 4a1 to move synchronously, disengaging the locking plug 4a1 from the socket 4b1 of the first guide sleeve 4b. This allows the mounting seat 4 to slide freely on the guide slide 2b, ensuring that the GPS body 1 maintains its elastic and shock-absorbing state during operation. When the cover 3 and housing 2 need to be separated, as the cover 3 moves upward, the lower top plate 3a disengages from the limiting bevel 4d3. The connecting spring 4d1, freed from external compression, recovers its deformation due to its own elastic force, pushing the two adjustment seats 4d away from each other and automatically returning the locking plug 4a1 to its initial state, locking the mounting seat 4. This embodiment automatically switches the locking and unlocking states of the mounting seat 4 through the coupling and separation of the cover 3 and housing 2, utilizing the cooperation of the lower top plate 3a, limiting bevel 4d3, and adjustment seats 4d, thereby significantly improving operational convenience and efficiency.

[0041] In order to ensure that the adjustment seat 4d can drive the locking plug 4a1 to move stably along the axis direction of the second guide sleeve 4b, the following features are specifically provided: The bottom of the housing 2 is provided with a T-shaped slide rail 2d extending horizontally along the radial direction of the guide slide rod 2b, and the adjustment seat 4d is slidably installed on the T-shaped slide rail 2d through T-shaped limit grooves 4d4 provided at both ends.

[0042] When the cover 3 is joined to the housing 2, the lower top plate 3a inside the cover 3 presses down on the retaining block 4d3 at the bottom of the adjustment seat 4d. This forces the adjustment seat 4d to move horizontally along the radial direction of the guide rod 2b, driving the locking plug 4a1 into the receptacle 4b1 of the first guide sleeve 4b. At this point, the T-shaped retaining grooves 4d4 at each end of the adjustment seat 4d slide on the T-shaped guide rail 2d at the bottom of the housing 2. The T-shaped structure restricts the adjustment seat 4d to horizontal movement along the extension direction of the T-shaped guide rail 2d, i.e., along the radial direction of the guide rod 2b, ensuring the accuracy of the adjustment seat 4d's movement path.

[0043] In order to ensure that the connection block 4a6 can maintain the connection relationship with the adjustment seat 4d when the mounting seat 4 moves along the guide slide 4b during driving, the following features are specifically provided: The upper side of the adjustment seat 4d is provided with an insertion groove 4d5 with the same thickness as the connecting block 4a6, and the connecting block 4a6 is inserted into the insertion groove 4d5. The bottom end of the connecting block 4a6 is provided with a connecting rod 4a7. The axis of the connecting rod 4a7 is parallel to the axis of the first guide sleeve 4b. The connecting rod 4a7 is inserted into the waist-shaped holes 4d6 provided on both sides of the insertion groove 4d5. The width of the waist-shaped hole 4d6 is the same as the diameter of the connecting rod 4a7. The waist-shaped hole 4d6 extends along the axial direction of the guide slide bar 2b.

[0044] When the vehicle-mounted positioning and orientation device is operating, vibrations generated by the vehicle's movement cause the mounting base 4 to move along the guide slide 2b. The locking plug 4a1 at the bottom of the mounting base 4 is connected to the adjustment base 4d via the connecting block 4a6. As the mounting base 4 moves along the guide slide 2b, the connecting block 4a6 moves with it. At this point, the connecting rod 4a7 at the bottom of the connecting block 4a6 slides within the waist-shaped holes 4d6 on either side of the insertion slot 4d5. Within the waist-shaped holes 4d6, the connecting rod 4a7 is able to move freely along the axis of the guide slide 2b to accommodate the sliding movement of the mounting base 4. This also ensures that the connecting rod 4a6 remains connected to the adjustment base 4d and does not fall off. This facilitates the connection block 4a6 to stably follow the movement of the adjustment base 4d during the splicing or separation of the cover 3 and the housing 2, ensuring that the locking plug 4a1 can accurately insert or exit the receptacle 4b1 of the first guide sleeve 4b.

[0045] In order to ensure the pushing effect of the lower top plate 3a on the adjustment seat 4d, the following features are specifically set: The width of the lower top plate 3a is greater than the width of the limiting inclined block 4d3, and the bottom end of the lower top plate 3a is a round head.

[0046] In this embodiment, the width of the lower top plate 3a is greater than the limiting bevel block 4d3, ensuring that the lower top plate 3a can accurately cover the limiting bevel block 4d3 during the descending process, thereby stably transmitting the pressure to the limiting bevel block 4d3. The round head design makes the lower top plate 3a smoother when sliding along the inclined surface of the limiting bevel block 4d3, reducing friction resistance and making the splicing operation of the cover body 3 and the shell 2 easier and smoother.

[0047] In order to achieve the purpose of buffering the shaking of the cable during driving, the following features are specifically set: The wire groove 2a1 is provided with a plurality of mounting holes 2a3 extending radially along the wire groove 2a1, and the elastic ball 2a2 is installed in the mounting hole 2a3. A second spring 2a4 is provided in the mounting hole 2a3. The second spring 2a4 elastically connects the elastic ball 2a2 and the bottom end of the mounting hole 2a3. The elastic force of the second spring 2a4 causes the elastic ball 2a2 to protrude from the inner wall of the wire groove 2a1 and contact the outer wall of the cable.

[0048] During vehicle operation, vibrations are transmitted through the vehicle body to the housing 2 and the GPS body 1, causing the cable within the cable slot 2a1 to vibrate. At this point, the elastic ball bearings 2a2 mounted on the inner wall of the cable slot 2a1 act as a buffer. When the cable undergoes radial displacement due to vibration, the outer wall of the cable squeezes the elastic ball bearings 2a2, which in turn compress the second spring 2a4 radially inward along the mounting hole 2a3. The second spring 2a4 absorbs vibration energy through elastic deformation, reducing the amplitude of cable vibration. When the cable undergoes axial displacement following the mounting base 4 and the GPS body 1, the elastic ball bearings 2a2 roll against the outer wall of the cable, reducing friction. The elastic deformation characteristics of the second spring 2a4 in this embodiment enable the elastic ball bearings 2a2 to automatically adjust their buffering force based on the vibration amplitude of the cable, effectively absorbing vibration energy of varying frequencies and intensities, significantly reducing stress at the interface between the cable and the GPS body 1, preventing loose connections caused by long-term vibration, and extending the service life of the device.

[0049] In order to limit the movement range of the mounting base 4 along the guide slide 2b and thus prevent the cables connected at both ends of the GPS body 1 from directly hitting the inner wall of the housing 2, the following features are specifically provided: The mounting seat 4 is provided with a plurality of main buffer pads 4e at both ends in the axial direction of the first guide sleeve 4b, and a plurality of positioning blocks 3b are provided at the bottom of the cover body 3. After the shell 2 and the cover body 3 are spliced ​​together, the mounting seat 4 is located between the two positioning blocks 3b, and the positioning block 3b is provided with a secondary buffer pad 3b1 on the same straight line as the main buffer pad 4e at one end facing the mounting seat 4.

[0050] During the driving process of the car, the vibration will cause the mounting seat 4 to slide along the guide slide bar 2b, driving the GPS body 1 and the connected cables to move together. The mounting seat 4 is located between the two positioning blocks 3b and moves, which accurately limits the movement range of the mounting seat 4, and prevents the cables connected at both ends of the GPS body 1 from hitting the inner wall of the shell 2 due to excessive sliding of the mounting seat 4, thereby preventing the outer sheath of the cable from being worn and the internal core wire from being broken. When the mounting seat 4 slides toward the positioning block 3b at one end, the main buffer block 4e at its end will gradually approach the secondary buffer block 3b1 on the positioning block 3b at the bottom of the cover body 3. As the mounting seat 4 continues to slide, the main buffer block 4e contacts the secondary buffer block 3b1. Since the two are in the same straight line, the secondary buffer block 3b1 cooperates with the main buffer block 4e to absorb the impact force when the mounting seat 4 hits the positioning block 3b.

[0051] In order to realize the splicing of the shell 2 and the cover 3, the following features are specifically set: The top of the shell 2 is provided with a plurality of through holes 2e, and the bottom of the cover body 3 is provided with fitting blocks 3c with the same number as the through holes 2e. The fitting blocks 3c are provided with threaded holes 3c1. After the shell 2 and the cover body 3 are spliced ​​together, the threaded holes 3c1 and the through holes 2e are in the same straight line. The shell 2 and the cover body 3 are screwedly installed in the through holes 2e from the outside of the shell 2 by screws 3d for locking.

[0052] During assembly of this embodiment, the GPS body 1 is first fixed to the mounting base 4. The cable is passed through the wire groove 2a1 of the wire guide 2a on the side where the housing 2 and cover 3 are joined. Subsequently, the cover 3 is placed over the top of the housing 2, aligning the threaded hole 3c1 on the fitting block 3c at the bottom of the cover 3 with the through hole 2e at the top of the housing 2. Next, a screw 3d is inserted from the outside of the housing 2 through the through hole 2e and into the threaded hole 3c1 on the fitting block 3c. By tightening the screw 3d, the cover 3 and the housing 2 are tightly joined, thus encapsulating and securing the internal components, such as the GPS body 1 and the mounting base 4.

[0053] Working principle: The staff first opens the cover 3 on the shell 2, and the lock 4a on the mounting seat 4 locks the position of the mounting seat 4 on the guide shaft 2b. Then the GPS body 1 is fixed on the mounting seat 4, and the cable connected to the GPS body 1 is passed through the wire groove 2a1 of the wire sleeve 2a on the spliced ​​side of the shell 2 and the cover 3. The elastic ball 2a2 fits the outer wall of the cable. The shell 2 is then installed on the car body and the cover 3 is closed. At this time, the lock 4a releases the lock on the mounting seat 4, and the mounting seat 4 can slide on the guide slide 2b. When the car vibrates during driving, the mounting seat 4 slides along the guide slide 2b accordingly. At this time, the first springs 2c at both ends can absorb the vibration energy and reduce the impact of the vibration on the GPS body 1.
