Description

Technical Field

[0001] This application relates to the field of children's racing car technology, and in particular to a motor mounting structure for a children's racing car. Background Technology

[0002] In the field of children's racing bikes, traditional motor mounting methods often lack effective shock absorption measures. Children encounter various complex road conditions while riding racing bikes, such as bumps and undulations. As the vehicle's power source, the motor is subjected to significant vibration and impact during operation. A mounting structure lacking shock absorption design results in a rigid connection between the motor and the bike body. Under vibration, the motor is prone to loosening, which not only affects its normal operation and leads to unstable power output, but may also damage the motor or other components due to collisions, shortening the vehicle's lifespan.

[0003] Meanwhile, the installation and disassembly process of existing motor mounting structures is usually quite cumbersome. When maintenance, replacement, or repair of the motor is required, operators need to spend a lot of time and effort to disassemble and reinstall the motor. This not only increases maintenance costs but also causes great inconvenience to users.

[0004] 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

[0005] Based on this, this application provides a motor mounting structure for a children's racing car to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: a motor mounting structure for a children's racing car, including: a car body and a motor. The car body has a mounting platform and a transmission assembly in the middle, and also includes: a motor compartment fixed on the mounting platform, with an insertion hole inside that communicates with the transmission assembly. Limiting grooves are formed on the inner walls of both sides of the motor compartment, and a slide rail is movably arranged in the limiting groove. One end of the slide rail rotates on the motor compartment. First shock-absorbing springs are arranged on the side walls of the motor compartment on the upper and lower sides of the limiting groove. The ends of the first shock-absorbing springs abut against the slide rail. An upwardly extending support column is formed on the bottom of the motor compartment. A second shock-absorbing spring is fixed to the top of the support column. A base plate rotates inside the motor compartment. The second shock-absorbing spring and the support column are used to support the base plate. The motor includes a splined output shaft thereon and a fixing plate fixed to the bottom of the motor. The motor is mounted in the motor compartment by sliding the fixing plate in the slide rail. The splined output shaft is connected to the transmission assembly by inserting into the insertion hole to realize transmission.

[0007] In some embodiments, the motor compartment has a triangular cross-section with an opening on one side. The opening of the motor compartment has a hinged cover that can be opened and closed. A retaining block extends from the hinged cover. When the hinged cover is locked in the motor compartment, the retaining block abuts against the motor.

[0008] In some embodiments, the flip cover is provided with a key lock, and the flip cover is locked to the motor compartment by the key lock.

[0009] In some embodiments, spring mounting columns are formed on both sides of the motor compartment, and the first shock-absorbing spring is fixedly installed inside the spring mounting columns.

[0010] In some embodiments, the slide rail rotates within the limiting groove, and the maximum deflection angle of its rotation is 5°.

[0011] In some embodiments, the transmission assembly includes a flexible coupling, and the splined output shaft of the motor is connected to the transmission assembly via the flexible coupling.

[0012] In some embodiments, a flexible rubber gasket is fixed on the inner wall of the insertion hole.

[0013] In some embodiments, the slide rail has a U-shaped structure with a sliding groove formed thereon for the fixed plate to slide.

[0014] The beneficial effects of this application are as follows: 1) The motor is installed by sliding on the slide rail through the fixed plate, which can realize quick assembly and disassembly. The motor and the transmission components are connected by splines and flexible couplings, which can effectively reduce the damage to the motor output shaft caused by the vibration environment and achieve long-term and stable transmission.

[0015] 2) After the motor is installed in the motor compartment, when the vehicle vibrates, the motor can rotate up and down slightly along with the slide rail under the action of the first and second damping springs. This damping design can effectively buffer the vibration impact on the motor during driving, reduce the loosening and damage caused by vibration, ensure the stable operation of the motor, improve the stability of the vehicle's power output, and extend the service life of the motor and other components.

[0024] 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.

[0025] In the embodiments of this application, please refer to Figure 1-6As shown, the motor mounting structure of this children's racing car mainly includes: a car body 1 and a motor 2. The car body 1 has a mounting platform 3 and a transmission assembly 4 in the middle, and also includes: a motor compartment 5, fixed on the mounting platform 3, with an insertion hole 6 inside communicating with the transmission assembly 4. Limiting grooves 7 are formed on the inner walls of both sides of the motor compartment 5, and slide rails 8 are movably arranged within the limiting grooves 7. One end of the slide rail 8 rotates on the motor compartment 5. First shock-absorbing springs 9 are provided on the side walls of the motor compartment 5 on both sides of the limiting grooves 7, with the ends of the first shock-absorbing springs 9 abutting against the slide rails 8. An upwardly extending support column 11 is formed on the inner bottom of the motor compartment 5, and a second shock-absorbing spring 10 is fixed to the top of the support column 11. The motor housing 5 contains a rotating base plate 12, and the second damping spring 10 and support column 11 support the base plate 12. The motor 2 includes a spline output shaft 201 and a fixing plate 202 fixed to the bottom of the motor 2. The motor 2 is installed in the motor housing 5 by sliding within the slide rail 8 through the fixing plate 202. The spline output shaft 201 is connected to the transmission assembly 4 by inserting into the insertion hole 6 to achieve transmission. After the motor 2 is installed in the motor housing 5 and connected to the transmission assembly 4, in a vibrating environment, the slide rail 8 and the motor 2 deflect, and rotate slightly up and down under the action of the first damping spring 9 and the second damping spring 10, which reduces the impact and avoids damage to the motor 2.

[0026] 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.

[0027] like Figure 2 As shown, the motor compartment 5 has a triangular cross-section with an opening 13 on one side. A hinged cover 14 that can be opened and closed is located at the opening 13 of the motor compartment 5. A retaining block 15 extends from the hinged cover 14. When the hinged cover 14 is locked in the motor compartment 5, the retaining block 15 abuts against the motor 2. The retaining block 15 abuts against the motor 2, which only limits the depth of the motor 2 sliding into the slide rail 8, so as to facilitate the subsequent connection between the motor 2 and the transmission component 4, without affecting the normal up and down rotation of the motor 2 and the slide rail 8.

[0028] Furthermore, the flip cover 14 is provided with a key lock 16, and the flip cover 14 is locked to the motor compartment 5 by the key lock 16. When it is necessary to replace or maintain the motor 2, simply use the key to open the flip cover 14 and disconnect the spline output shaft 201 from the transmission assembly 4 to pull out the motor 2.

[0029] Furthermore, spring mounting posts 17 are formed on both sides of the motor compartment 5, and the first damping spring 9 is fixedly installed in the spring mounting post 17. The first damping spring 9 can provide a restoring force to the slide rail 8 in the longitudinal direction, so that the slide rail 8 and the motor 2 can rotate slightly within the limit groove 7.

[0030] Specifically, the slide rail 8 rotates within the limiting groove 7, with a maximum deflection angle of 5°. The small-amplitude rotation of the slide rail 8 motor 2 can both reduce vibration and minimize damage to the spline output shaft 201 of the motor 2 caused by the up-and-down rotation.

[0031] Furthermore, the transmission assembly 4 includes a flexible coupling. The spline output shaft 201 of the motor 2 is connected to the transmission assembly 4 through the flexible coupling. The spline output shaft 201 can be quickly inserted into the transmission assembly 4 for transmission. The flexible coupling further fixes the transmission assembly 4 and the spline output shaft 201 and reduces damage to the spline output shaft 201 during vibration.

[0032] like Figure 6 As shown, a flexible rubber gasket 18 is fixed on the inner wall of the insertion hole 6. The flexible rubber gasket 18 and the flexible coupling work together to protect the spline output shaft 201, thereby ensuring the normal transmission of the spline output shaft 201.

[0033] Furthermore, the slide rail 8 has a U-shaped structure, on which a sliding groove 19 is formed for the fixed plate 202 to slide.

[0034] When in use, first open the flip cover 14, place the motor 2 into the motor compartment 5 through the opening 13, and slide the fixing plate 202 in the sliding groove 19 of the slide rail 8. At this time, the spline output shaft 201 of the motor 2 is inserted into the insertion hole 6. Then, fix the spline output shaft 201 and the transmission assembly 4 through the flexible coupling to complete the installation. Then close the flip cover 14.
