Description

Technical Field

[0001] This application relates to the field of children's off-road vehicle technology, and in particular to a children's electric off-road vehicle frame. Background Technology

[0002] Children's off-road vehicles are electric toy cars designed specifically for children. They are capable of adapting to complex terrains, and their core features include off-road performance, safety design, and entertainment attributes.

[0003] In traditional children's off-road vehicles, the child's seat (or seat mounting plate) is usually rigidly installed to the frame floor. This rigid connection provides good support and stability during normal driving, but it is difficult to effectively absorb the impact force when the vehicle is subjected to lateral impact. The impact force is transmitted directly to the seat and the occupant with almost no attenuation.

[0004] Based on this, this application aims to provide a vehicle frame with a more complete protective structure, which can realize the functions of shock absorption and shock absorption when the seat mounting mechanism and seat are impacted.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0006] Based on this, this application provides a frame for a child electric off-road vehicle to solve one of the aforementioned technical problems.

[0007] The technical solution adopted by this application to solve its technical problem is: a children's electric off-road vehicle frame, including: a base plate, on which a main frame is mounted, the main frame of which is a triangular truss structure made of hollow tubing, and a number of reinforcing tubes are provided on the main frame; a front anti-collision barrier and a rear anti-collision barrier are respectively provided at the front and rear ends of the base plate; two parallel sliding grooves are opened at the center of the top of the base plate, and receiving holes are opened on the two inner walls of the sliding grooves along their length; an anti-collision shock absorption mechanism is disposed in the sliding grooves and receiving holes, including a shock-absorbing spring, a contact rod and a slider, the spring being assembled in the receiving hole, one end of the contact rod being fixed to the shock-absorbing spring, the slider being disposed in the sliding groove, and the other end of the contact rod abutting against the slider; the two sliders are integrally formed on the same seat mounting plate; the anti-collision shock absorption mechanism can play a role in shock absorption and shock absorption when the off-road vehicle is subjected to lateral impact.

[0008] In some embodiments, the ends of the front and rear guardrails are provided with rubber layers.

[0009] In some embodiments, the bottom end of the receiving hole is lower than the bottom of the slide, and the shock-absorbing spring can only move within the receiving hole.

[0010] In some embodiments, a contact plate is fixed to one end of the contact rod near the slider, and the contact plate contacts the slider.

[0011] In some embodiments, a through groove is provided on the base plate at the center of the two slides, and a threaded hole communicating with the slide is provided on the side wall of the through groove, the threaded hole being used for threaded assembly of a locking pin.

[0012] In some embodiments, the locking pin includes a threaded section and a pin section, the slider has a insertion hole, the pin section is used to insert into the insertion hole, and the locking pin is used to fix the slider and the position of the mounting plate.

[0013] In some embodiments, when the impact force on the off-road vehicle reaches a preset threshold, the threaded section and the pin section disconnect, the slider unlocks and locks, and can move within the groove, thus activating the anti-collision and shock absorption mechanism.

[0014] In some embodiments, the top of the slide is provided with a mounting groove to facilitate the assembly of the slider and the contact rod.

The frame has complete protective function and a large protective area, which can play a good protective role.

[0018] 2) The seat mounting plate is located at the center of the anti-collision and shock absorption mechanism. During normal driving, the slider integrated with the seat mounting plate is fixed in the groove by the locking pin. When an impact occurs and the impact force reaches the preset value, the threaded section and the pin section of the locking pin break, the slider is unlocked and slides in the groove, and the contact rods and shock-absorbing springs on both sides of the slider play a role in transmitting and absorbing part of the impact force generated during the impact, which can further protect the safety of the driver.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0031] In the embodiments of this application, please refer to Figure 1-9As shown, the frame of this children's electric off-road vehicle mainly includes: a base plate 1, on which a main frame 2 is mounted. The main frame of the main frame 2 is a triangular truss structure made of hollow tubing. Several reinforcing tubes 3 are provided on the main frame 2. A front anti-collision barrier 4 and a rear anti-collision barrier 5 are respectively provided at the front and rear ends of the base plate 1. Two parallel sliding grooves 6 are opened at the center of the top of the base plate 1. Accommodation holes 7 are opened on the two inner walls of the sliding grooves 6 along their length. An anti-collision shock absorption mechanism is set in the sliding grooves 6 and the accommodation holes 7, including a shock-absorbing spring 8, a contact rod 9, and a slider 10. The spring is assembled in the accommodation hole 7. One end of the contact rod 9 is fixed to the shock-absorbing spring 8. The slider 10 is set in the sliding groove 6. The other end of the contact rod 9 abuts against the slider 10. The two sliders 10 are integrally formed on the same seat mounting plate 18. The anti-collision shock absorption mechanism can play a role in shock absorption and shock absorption when the off-road vehicle is subjected to lateral impact.

[0032] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0033] like Figure 1 As shown, the front bumper 4 and the rear bumper 5 are provided with rubber layers 11 at their ends. The front bumper 4 and the rear bumper 5, as well as the rubber layers 11 on them, can play a certain protective role when the off-road vehicle is hit from the front and rear, thus ensuring the safety of the user.

[0034] like Figure 4 As shown, the bottom of the receiving hole 7 is lower than the bottom of the slide groove 6, and the shock-absorbing spring 8 can only move within the receiving hole 7. The contact rod 9, which is fixed to the shock-absorbing spring 8, can move horizontally within the receiving hole 7 and the slide groove 6. After the contact rod 9 is subjected to the pressure (impact force) of the slider 10, it can transmit the force to the shock-absorbing spring 8. The shock-absorbing springs 8 on both sides are alternately compressed and relaxed, thereby playing a damping role and reducing the impact force on the seat mounting plate 18 and the seat on it.

[0035] like Figure 7 As shown, a contact plate 12 is fixed to one end of the contact rod 9 near the slider 10. The contact plate 12 contacts the slider 10. Limiting grooves are formed on both sides of the bottom of the slide groove 6. The bottom of the contact plate 12 and the slider 10 have lugs that are consistent with the shape of the limiting grooves. The contact plate 12 can not only limit the contact rod 9, but also increase the contact area between the contact rod 9 and the slider 10, transmit the impact force more evenly, and extend the service life of the component.

[0036] like Figure 3 and Figure 5-6As shown, a through groove 13 is provided on the bottom plate 1 at the center of the two grooves 6. A threaded hole 14 communicating with the groove 6 is provided on the side wall of the through groove 13. The threaded hole 14 is used for threaded assembly of a locking pin 15. The threaded hole 14 and the locking pin 15 are preferably provided on the two inner walls of the through groove 13.

[0037] Furthermore, combined with Figure 8-9 As shown, the locking pin 15 includes a threaded section 1501 and a pin section 1502. The slider 10 has a insertion hole 19. The pin section 1502 is used to insert into the insertion hole 19. The locking pin 15 is used to fix the slider 10 and the position of the mounting plate. The threaded section 1501 is screwed to the threaded hole 14 through the thread. The pin section 1502 is used to directly limit the slider 10. The interface between the threaded section 1501 and the pin section 1502 is flush with the side wall of the slide groove 6.

[0038] Furthermore, when the impact force on the off-road vehicle reaches a preset threshold, the threaded section 1501 and the pin section 1502 disconnect, the slider 10 unlocks and locks, and can move within the slide groove 6. The anti-collision shock absorption mechanism then functions. The preset pressure value for the disconnection of the threaded section 1501 and the pin section 1502 can be adjusted at the factory according to the processing method of the combination of the threaded section 1501 and the pin section 1502. The disconnection threshold of the locking pin 15 used by children aged 4-7 is preferably 5 kN, and the disconnection threshold of the locking pin 15 used by children aged 8-12 is preferably 7 kN. After disconnection, it can be replaced or not. Not replacing it will not affect the normal use of the off-road vehicle. The shock-absorbing spring 8 can be a spring with a suitable elastic coefficient to prevent excessive shaking of the seat mounting seat 18 and the seat during normal use (braking, etc.).

[0039] Furthermore, the top of the slide groove 6 is provided with a mounting groove 16 to facilitate the assembly of the slider 10 and the contact rod 9.

[0040] In addition, such as Figure 3 The base plate 1 is provided with a motor mounting position 17.

[0041] When the frame of this application is in use, the main frame 2 and the reinforcing tubes 3 of the truss structure on it provide extensive protection for the driver. The triangular frame structure further improves stability and safety. The front bumper 4 and rear bumper 5 in front of and behind the floor plate 1 can reduce the damage from front and rear impacts and further improve safety performance. When the impact on the off-road vehicle frame reaches the threshold, the threaded section 1501 and the pin section 1502 of the locking pin 15 disconnect from each other, the slider 10 unlocks and can slide freely in the groove 6, and transmits the impact force to the contact rod 9 and the shock absorber spring 8, reducing the impact on the seat mounting plate 18 and the seat during the impact.
