Description

Technical Field

[0001] This utility model relates to the field of passenger seat technology, specifically to a passenger seat with multiple folding functions. Background Technology

[0002] Mining dump trucks are difficult to drive and require on-board guidance. Most rigid trucks follow the seating arrangement concept of heavy-duty highway trucks, with a single driver's seat in front of the cab and a large bunk bed behind it. This design is only suitable for situations where the cab space is large enough. However, when the cab space is limited, there is no reasonable space behind the driver's seat to place a passenger seat. In such cases, a foldable passenger seat is needed to improve space utilization. Patent number CN202421208644.5 discloses a foldable passenger seat, cab, and mining dump truck. When not in use, the seat board can be folded up, allowing for easy passage of personnel in front of the seat cushion. When in use, the seat cushion can be simply pulled down and laid flat. However, because the height of the passenger seat is fixed, it is not easily adjustable to meet the user's needs, thus limiting its usability. Therefore, we propose a passenger seat with multiple folding functions. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a passenger seat with multiple folding functions.

[0004] The technical solution adopted by this utility model to solve its technical problem is a passenger seat with multiple folding functions, including a seat body. The back of the seat body has an integrally constructed support strip, and a base that fits into the seat body is snapped onto the outer periphery of the support strip. The inner side of the base is provided with a sliding groove, and there are multiple sets of sliding grooves. A steel ball that fits into the support strip is slidably installed in the sliding groove, and a spring A for pushing the steel ball to move is installed in the sliding groove.

[0005] The outer two sides of the seat body are provided with sliding holes for adjustment, and there are multiple sets of sliding holes. End caps for sealing are screwed into the sliding holes. The inner circumference of the base is provided with pin holes that are adapted to the sliding holes, and there are multiple sets of pin holes. A cross ring rod that is inserted into the pin hole is slidably installed in the sliding hole. A spring B for pushing the cross ring rod to move is assembled between the end cap and the cross ring rod.

[0006] By adopting the above technical solution, during the use of the foldable passenger seat, the seat body can be pulled, causing the seat body to move the locking strip up and down on the base surface. The springs in the multiple sets of grooves on the inner circumference of the base can push the steel ball, so that one end of the steel ball can extend out of the groove and fit into the groove on the outer circumference of the locking strip, which can provide a certain limiting performance for the locking strip. This allows the seat body on the outer side of the base to be raised and lowered more stably and can be adjusted according to the user's needs, making it convenient for people to use.

[0007] After adjusting the height of the seat body on the outer periphery of the base, the spring B in the sliding hole on the outer periphery of the seat body can push the cross ring rod, so that one end of the cross ring rod can extend out of the sliding hole and interlock with the pin hole on the inner periphery of the base, thereby facilitating the locking and fixing of the adjusted distance, making the seat body on the outer periphery of the base more stable and convenient for people to use.

[0008] Specifically, a pull ring is fitted at one end of the cross ring rod located outside the sliding hole, and a threaded ring is integrally constructed on the outer circumference of the cross ring rod to be screwed into the end cap.

[0009] By adopting the above technical solution, when adjusting the height of the seat body on the outer periphery of the base, the cross ring rod in the sliding hole on the outer periphery of the seat body can be pulled by the pull ring, so that the cross ring rod can squeeze the spring B in the sliding hole and drive the threaded ring and the end cap to engage with each other, which makes it easy to limit the position of the cross ring rod, and then the height of the seat body on the outer periphery of the base can be adjusted.

[0010] Specifically, the inner circumference of the card strip is equipped with magnetic blocks that fit with the steel ball, and there are multiple sets of magnetic blocks.

[0011] By adopting the above technical solution, the magnetic block can be easily connected to the steel ball by magnetic attraction, which can improve the stability when the steel ball and the card strip are engaged.

[0012] Specifically, the base has a groove on the side near the seat body, and there are multiple sets of grooves. The rear surface of the seat body has an integrally constructed protrusion that matches the groove, and there are multiple sets of protrusions.

[0013] By adopting the above technical solution, the protrusions and grooves fit together, which facilitates the stability of the connection between the base and the seat body and makes it easier to make more stable adjustments later.

[0014] Specifically, the base has mounting holes on its outer periphery, and there are multiple sets of mounting holes.

[0015] By adopting the above technical solution, the multiple sets of mounting holes on the outer periphery of the base facilitate the fixing of the base position, enabling the base to be installed in a suitable position for convenient use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a locking strip, base, slide groove, steel ball, and spring A, allows the seat body to be pulled during the use of the foldable passenger seat. This causes the seat body to move the locking strip up and down on the base surface. The springs in the multiple slide grooves on the inner circumference of the base can push the steel ball, allowing one end of the steel ball to extend out of the slide groove and engage with the groove on the outer circumference of the locking strip. This provides a certain limiting performance for the locking strip, enabling the seat body on the outer side of the base to be raised and lowered more stably and adjusted according to the user's needs, making it convenient for users.

[0018] 2. The technical solution of this application, through the design of sliding holes, end caps, cross ring rods, pin holes and spring B, allows the spring B in the sliding hole on the outer periphery of the seat body to push the cross ring rod after the height of the seat body is adjusted. This allows one end of the cross ring rod to extend out of the sliding hole and interlock with the pin hole on the inner periphery of the base, thereby facilitating the locking and fixing of the adjusted distance. This makes the seat body on the outer periphery of the base more stable and convenient for users. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a passenger seat with multiple folding functions, including a seat body 1. The back of the seat body 1 has an integrally constructed support strip 2, and the outer periphery of the support strip 2 is engaged with a base 3 that fits into the seat body 1. The inner side of the base 3 has a sliding groove 4, and there are multiple sets of sliding grooves 4. A steel ball 5 that fits into the support strip 2 is slidably installed in the sliding groove 4, and a spring A6 for pushing the steel ball 5 to move is installed in the sliding groove 4. The outer two sides of the seat body 1 have sliding holes 7 for adjustment, and there are multiple sets of sliding holes 7. An end cap 8 for sealing is screwed into the sliding hole 7, and the inner periphery of the base 3 has pin holes 10 that are adapted to the sliding holes 7, and there are multiple sets of pin holes 10. A cross ring rod 9 that is inserted into and connected to the pin hole 10 is slidably installed in the sliding hole 7, and a spring B12 for pushing the cross ring rod 9 to move is installed between the end cap 8 and the cross ring rod 9.

[0026] When in use, the foldable passenger seat can be pulled to move the seat body 1, causing the seat body 1 to move the locking strip 2 to slide and rise on the surface of the base 3. The springs in the multiple sets of sliding grooves 4 on the inner circumference of the base 3 can push the steel ball 5, so that one end of the steel ball 5 can extend out of the sliding groove 4 and fit into the groove on the outer circumference of the locking strip 2, which can provide a certain limiting performance for the locking strip 2. This allows the seat body 1 on the outer side of the base 3 to be raised and lowered more stably and can be adjusted according to the user's needs, making it convenient for the user.

[0027] After adjusting the height of the seat body 1 on the outer periphery of the base 3, the spring B12 in the sliding hole 7 on the outer periphery of the seat body 1 can push the cross ring rod 9, so that one end of the cross ring rod 9 can extend out of the sliding hole 7 and be inserted into the pin hole 10 on the inner periphery of the base 3, thereby facilitating the locking and fixing of the adjusted distance, making the seat body 1 on the outer periphery of the base 3 more stable and convenient for people to use.

[0028] like Figure 2 and Figure 3 As shown, a pull ring 11 is fitted at one end of the cross ring rod 9 located outside the sliding hole 7, and a threaded ring 13 is integrally constructed on the outer circumference of the cross ring rod 9 and is screwed into the end cover 8.

[0029] When using the base 3, when adjusting the height of the seat body 1 on the outer periphery of the base 3, the cross ring rod 9 in the sliding hole 7 on the outer periphery of the seat body 1 can be pulled by the pull ring 11. This allows the cross ring rod 9 to squeeze the spring B12 in the sliding hole 7 and drive the threaded ring 13 to engage with the end cap 8. This makes it easy to limit the position of the cross ring rod 9, and then the height of the seat body 1 on the outer periphery of the base 3 can be adjusted.

[0030] like Figure 2 As shown, the inner circumference of the card strip 2 is equipped with a magnetic block 14 that matches the steel ball 5, and there are multiple sets of magnetic blocks 14.

[0031] When in use, the magnetic block 14 can be magnetically connected to the steel ball 5, which can improve the stability of the steel ball 5 and the card strip 2 when they are engaged.

[0032] like Figure 2 As shown, the base 3 has a groove 15 on the side near the seat body 1, and there are multiple sets of grooves 15. The rear side of the seat body 1 has a raised strip 16 that matches the groove 15, and there are multiple sets of raised strips 16.

[0033] When in use, the protrusion 16 and the groove 15 fit together, which helps to improve the stability of the connection between the base 3 and the seat body 1, and facilitates more stable adjustment in the future.

[0034] like Figure 2 As shown, mounting holes 17 are provided on the outer periphery of the base 3, and there are multiple sets of mounting holes 17.

[0035] When in use, the multiple sets of mounting holes 17 on the outer periphery of the base 3 make it easy to fix the position of the base 3, so that the base 3 can be installed in a suitable position for convenient use by personnel.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in the appropriate positions. When using the foldable passenger seat, pull the seat body 1, causing the seat body 1 to move the locking strip 2 up and down on the surface of the base 3. The springs in the multiple sets of grooves 4 on the inner circumference of the base 3 push the steel ball 5, allowing one end of the steel ball 5 to extend out of the groove 4 and engage with the groove on the outer circumference of the locking strip 2, providing a certain limiting function for the locking strip 2. This allows the seat body 1 on the outer side of the base 3 to be raised and lowered more stably, and can be adjusted according to the user's needs for convenient use. When adjusting the height of the seat body 1 on the outer circumference of the base 3… The cross ring rod 9 in the sliding hole 7 on the outer periphery of the seat body 1 can be pulled by the pull ring 11, so that the cross ring rod 9 can squeeze the spring B12 in the sliding hole 7 and drive the threaded ring 13 to engage with the end cap 8, which facilitates the position limit of the cross ring rod 9. Then, the height of the seat body 1 on the outer periphery of the base 3 can be adjusted. After the height of the seat body 1 on the outer periphery of the base 3 is adjusted, the spring B12 in the sliding hole 7 on the outer periphery of the seat body 1 can push the cross ring rod 9, so that one end of the cross ring rod 9 can extend out of the sliding hole 7 and be inserted into the pin hole 10 on the inner periphery of the base 3, which facilitates locking and fixing the adjusted distance, making the seat body 1 on the outer periphery of the base 3 more stable and convenient for people to use.
