Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.

The following describes the roof frame 3 according to an embodiment of the present application with reference to fig. 4 to 5.

According to the top wheel frame 3 of the embodiment of the application, the top wheel frame 3 is suitable for being arranged on a toy, and the bottom of the toy is provided with a running system for driving the toy to move.

The top wheel frame 3 is provided with a top wheel 33 capable of moving up and down and an elastic piece 39, and the elastic piece 39 is used for driving the top wheel 33 to move upwards.

The top wheel 33 is suitable for being arranged at the top end of the toy, the height of the highest point of the top wheel 33 on the toy is suitable for being larger than or equal to the height of the highest point of the rest part of the toy, when the top wheel frame 3 meets the top surface of the top, the top wheel 33 can be adaptively adjusted in height under the elastic force of the elastic piece 38, so that the top wheel 33 is in rolling contact with the top surface while the running system of the toy is in contact with the ground, and the toy can run vertically or run upside down on the ground with the top surface.

Here, the toy may be a toy car, or may be a toy of another shape, such as a toy frog, a toy rabbit, or the like. The top wheel frame 3 is arranged on the toy, so that the toy can form rolling contact support at the top, when the toy runs under the road condition with the top surface of the top, for example, the toy runs on a track or road with the top wall under the support of the top wheel frame, even if the toy runs on a vertical or inverted track, the top wheel frame 3 can be adaptively adjusted according to the distance between the top wall and the bottom wall of the track, so that a bottom running system of the toy and the top wheel 33 are respectively in full contact with the top wall and the bottom wall of the track, but are not blocked or fall off from the track. By the supporting action of the top wheel frame 3 on the top wall, the toy can run on a large slope or in an inverted condition. The function and specific structure of the crown wheel frame 3 will be described in detail below with respect to the structure of the toy vehicle 100, and will not be described again here.

A toy vehicle 100 in accordance with an embodiment of the present application is described below with reference to fig. 1-6.

Toy vehicle 100, as shown in fig. 1 and 3, according to an embodiment of the present application, includes: a vehicle body 1, a wheel frame 2 and a top wheel frame 3. The wheel frame 2 is provided on the vehicle body 1, and wheels 211 are provided on the wheel frame 2. The top wheel frame 3 is arranged on the vehicle body 1 or the vehicle wheel frame 2, the top wheel frame 3 is provided with a top wheel 33 which can move up and down and an elastic piece 38, and the elastic piece 38 is used for driving the top wheel 33 to move upwards.

The height H2 of the highest point of the top wheel 33 is equal to or greater than the height H1 of the highest point of the vehicle body 1, and when the top wheel frame 3 encounters the top surface, the top wheel 33 can be adaptively adjusted in height by the elastic force of the elastic member 38, so that the top wheel 33 is in rolling contact with the top surface while the wheel 211 is in contact with the ground, and the toy 100 can travel vertically or reversely on the ground having the top surface.

Here, as shown in fig. 2, the height H1 of the highest point of the vehicle body 1 is a height difference between the highest point of the vehicle body 1 and the lowest point of the wheel 211, and the height H2 of the highest point of the top wheel 33 is a height difference between the highest point of the top wheel 33 and the lowest point of the wheel 211.

Thus, when toy vehicle 100 is traveling on a normal road surface, toy vehicle 100 may travel normally unaffected.

And when toy vehicle 100 is traveling on a road surface having a top surface, if top wheels 33 on toy vehicle 100 are capable of rolling contact with the top surface of the top, the contact point of toy vehicle 100 with the exterior increases and toy vehicle 100 can travel more smoothly. Also on such ground, the toy vehicle 100 may travel on any grade (1-180 degrees).

For example, on the toy track assembly 200 shown in fig. 6, the toy track assembly 200 may include a flat rail section 201, a turn section 202, a climbing section 203, a downhill section 204, a vertical climbing section 205, a vertical downhill section 206, and an inverted section 207. The toy track assembly 200 is provided with a bottom wall 210 and side walls 220 on both sides of the bottom wall 210 throughout the course, and the toy track assembly 200 is provided with a top cover at the climbing section 203, the downhill section 204, the vertical climbing section 205, the vertical downhill section 206, and the inverted section 207 to form a top wall 230.

If toy vehicle 100 is traveling on the toy track assembly 200, the track bottom wall 210 is positioned below toy vehicle 100 and bottom wall 210 forms a load bearing wall when toy vehicle 100 is traveling on flat track section 201, turn section 202, ramp section 203, or ramp section 204.

When toy vehicle 100 enters ramp 203, top wheel 33 of toy vehicle 100 may come into rolling contact with track top wall 230, allowing toy vehicle 100 to smoothly ramp. The wheels 211 of the toy vehicle 100 may then still abut the track bottom wall 210 under the support of the top wheels 33 as the toy vehicle 100 enters the vertical climbing section 205. The driving force transmitted to the wheels 211 by the driving motor of the toy vehicle 100 is greater than the sum of the friction between the toy vehicle 100 and the track and the weight of the toy vehicle 100 so that the toy vehicle 100 can climb vertically upward.

When the toy car 100 enters the inverted section 207, the track is inverted, the track bottom wall 210 is positioned above the track top wall 230, the wheels 211 run on the track bottom wall 210, the top wheel 33 is supported on the track top wall 230, the track top wall 230 forms a bearing wall, and the wheels 211 of the toy car 100 can still run against the track bottom wall 210 under the support of the top wheel 33. The driving force transmitted to the wheels 211 by the driving motor of the toy vehicle 100 is greater than the friction of the toy vehicle 100 with the track, so that the toy vehicle 100 can travel upside down.

It should be noted that the toy-travelable floor referred to herein includes not only the toy track assembly 200 of fig. 6, but also the top surface is not limited to the track top wall 230, and may be considered as a track when the toy vehicle 100 travels on other roads. For example, when toy vehicle 100 is traveling indoors and drilling under a table, the small space between the table bottom and the ground forms the track of toy vehicle 100, the ground forms the track bottom wall, and if top wheels 33 of toy vehicle 100 are capable of rolling contact with the table bottom surface, the table bottom surface forms the track top wall. That is, the novel toy vehicle 100 of the present application may travel not only on a toy track assembly 200 specifically designed for the toy vehicle 100, but also on other suitable roads. For ease of understanding, toy vehicle 100 is described below as traveling on toy track assembly 200.

According to the toy car 100 of the embodiment of the application, by arranging the top wheel frame 3 with the top wheels 33, the toy car 100 can form rolling contact support at the top, and when the toy car 100 runs under road conditions with top walls, for example, the toy car 100 can stably run on a high-gradient track under the support of the top wheel frame 3, and even can run on a track vertical to the ground or an inverted track, so that the toy car 100 has more interest.

The structure of the roof frame 3 according to an embodiment of the present application will be described below with reference to fig. 3 to 5.

In some embodiments of the present application, the top wheel frame 3 may be fixedly connected to the vehicle body 1 or the vehicle wheel frame 2, and the top wheel frame 3 may also be detachably connected to the vehicle body 1 or the vehicle wheel frame 2.

In some embodiments, the top wheel frame 3 may be telescopically provided on the vehicle body 1 or the wheel frame 2, so that the height H2 of the highest point of the top wheel 33 can be adjusted on different rails according to the distance between the bottom wall 210 and the top wall 230 of the rail.

Here, there are various structural forms of telescopic adjustment of the roof frame 3, for example, the roof frame 3 may include an upper section portion and a lower section portion, the lower section portion is connected to the vehicle body 1 or the vehicle frame 2, the upper section portion is provided on the lower section portion so as to be slidable up and down, and the roof wheel 33 is provided on the top end of the upper section portion. An elastic block can be arranged between the upper section and the lower section and is used for pushing the upper section upwards. Thus, the elastic block is compressed downwards when the upper section is compressed, and the upper section is released and then restored, so that the top wheel frame 3 can adaptively adjust the height under the elastic force of the elastic block through the expansion and contraction of the upper section relative to the lower section when encountering the top surface of the top.

Alternatively, the lower section is formed as a liquid-filled tube, the upper section is slidably disposed in the tube up and down, and the upper section is configured to push the top wheel 33 normally upward under the hydraulic drive in the lumen.

In fig. 3-5, a top frame 3 is mentioned, the height H2 of the top wheel 33 of the top frame 3 also being adjustable.

Specifically, as shown in fig. 4 and 5, the roof frame 3 includes: the support member 31, the swinging member 32 and the elastic member 38, the support member 31 is connected with the vehicle body 1 or the vehicle wheel frame 2, the swinging member 32 is rotatably provided on the support member 31, the top wheel 33 is provided on the swinging member 32, and the elastic member 38 is connected between the support member 31 and the swinging member 32. Under the action of the elastic element 38, the top wheel frame 3 can swing adaptively according to the distance between the bottom wall 210 and the top wall 230 of the track, so as to ensure that the wheels 211 and the top wheel 33 are contacted with the bottom wall 210 and the top wall 230 of the track respectively with a certain friction force, and thus, when the applicability of the toy car 100 is increased, the interest is also enhanced.

Specifically, as shown in fig. 4, the swing member 32 extends obliquely upward and rearward, a top wheel 33 is provided at an upper end of the swing member 32, and elastic members 38 are respectively attached to the front sides of the support member 31 and the swing member 32.

Thus, when the vehicle 100 is driven into the section of track with the top wall 230, the friction between the top wheels 33 as they come into contact with the top wall 230 causes the oscillating member 32 to rotate rearward. After the swing member 32 rotates backward, the elastic member 38 pulls the upper end of the swing member 32 to rotate forward, so that the top wheel 33 at the upper end of the swing member 32 can contact with the top wall 230, thereby completing the self-adaptation process of the top wheel frame 3.

Here, in the natural state of the toy car 100 (the toy car 100 is not in the track), the swinging member 32 on the top wheel frame 3 is not arranged in a vertical state, but the lower end of the swinging member 32 is near the front upper end, so that when the toy car 100 runs, the front side of the toy car approaches the top wall 230 when encountering the track top wall 230, and the running direction of the toy car 100 is consistent with the swinging direction of the swinging member 32, thereby avoiding the phenomenon that the toy car 100 is blocked.

Specifically, as shown in fig. 5, the support 31 includes: the fixing part 311 and the connecting part 312, the fixing part 311 is formed in an inverted T shape, and both ends of the bottom of the fixing part 311 are fixed on the vehicle body 1 or the vehicle wheel frame 2 through the first connecting piece 34. In the embodiment of fig. 5, the first connector 34 includes a pair of bolts. The connection part 312 is provided at an upper end of the fixing part 311, and the connection part 312 is provided with a connection groove 3121 opened front and back and opened upward.

Specifically, as shown in fig. 5, the lower end of the swinging member 32 extends into the connection groove 3121, and the swinging member 32 is rotatably connected to the connection portion 312 by the second connection member 35, and in the embodiment of fig. 5, the second connection member 35 is a bolt. The upper end of the swinging member 32 is provided with a mating groove 321 which is opened front and back and opened upward, the top wheel 33 is rotatably provided in the mating groove 321, the top wheel 33 is rotatably connected with the swinging member 32 by a third connecting member 36, and in the embodiment of fig. 5, the third connecting member 36 is a bolt.

Specifically, as shown in fig. 5 and 3, gaskets 37 are further provided on both sides of the top wheel 33 to reduce friction at the connection of the top wheel 33 and the swinging member 32. Of course, in the present application, a bearing (not shown) may be provided, so that the top wheel 33 receives less friction. Wherein the spacer 37 may be omitted if the bearing is provided.

Specifically, the top wheel 33 may be an integrally formed metal wheel or plastic wheel, or may be a roller formed by sleeving a rubber tyre on an outer layer of a metal and/or plastic hub.

In particular, as shown in fig. 3 and 5, the elastic member 38 is a spring, so that the assembly is very easy. Of course, the elastic member 38 may be a torsion spring.

As shown in fig. 3, the front side of the supporting member 31 may be provided with a first bump 313 with a hole, the front side of the swinging member 32 may be provided with a second bump 322 with a hole, the upper end of the spring is inserted into the hole on the second bump 322, the lower end of the spring is inserted into the hole on the first bump 313 (fig. 3 only shows the state that the spring is located between the first bump 313 and the second bump 322, and the connection state of the spring and the hole on the two is not shown), thereby elastically connecting the swinging member 32 with the supporting member 31.

The height H3 of the support 31 is preferably less than 50mm.

Further, as shown in fig. 2, the toy vehicle 100 is provided with top wheels 33 at both the front and rear ends, and the height H21 of the highest point of the top wheels 33 at the front end is lower than the height H22 of the highest point of the top wheels 33 at the rear end. Such a low front and high rear arrangement facilitates smooth entry of toy vehicle 100 into track with top wall 230.

Specifically, if top wall 230 of the track is low, top wall 230 is highly strenuous to toy vehicle 100 when toy vehicle 100 just enters the track with top wall 230, and top wheel 33 with a low front end is in contact with top wall 230 first, so that toy vehicle 100 can be guaranteed to drive smoothly into the track. When the front top wheel 33 of the toy car 100 contacts the top wall 230 of the track and then the top wheel 33 of the rear end of the toy car 100 contacts the top wall 230, the impact applied to the toy car 100 is relatively reduced, the buffer time for the rear swing member 32 to rotate backwards is given, and the rear top wheel 33 can be smoothly contacted with the top wall 230. If the top wall 230 of the track is high, then the top wheel 33 at the front end of the toy vehicle 100 may not contact the top wall 230 as soon as the toy vehicle 100 enters the track with the top wall 230, and the toy vehicle 100 is supported by the top wheel 33 at the rear end. Because the top wall 230 is high, the swing member 32 at the rear end needs to be rotated backward by a small amount, and the top wheel 33 at the rear end can be smoothly brought into contact with the top wall 230.

It should be noted that, in the above embodiments, the top wheel 33 is referred to as a roller, but in other embodiments of the present application, the top wheel 33 may be a ball, a universal wheel, or the like.

In addition, the top wheel frames 3 mentioned in the above embodiment are described, only one top wheel 33 is provided on each top wheel frame 3, but in other embodiments of the present application, a plurality of top wheels 33 may be provided on one top wheel frame 3.

The roof rail 3 may be provided singly or in plurality at any position of the vehicle body 1.

When the top wheel frame 3 is single, the top wheel frame 3 can be arranged on the symmetrical central line of the vehicle body 1; when the roof frames 3 are one or more groups, two roof frames 3 of each group may be symmetrically disposed with respect to the center point and/or the center line of the vehicle body 1.

In some embodiments, as shown in fig. 1 and 3, the wheel frame 2 includes: the wheel frame 21 and the wheel frame 22 are formed with lateral rotation shafts on opposite sides of the frame 21, and the wheels 211 rotate around the lateral rotation shafts to drive the wheel frame 2 to move toward the traveling direction of the toy vehicle 100. The guide wheel frame 22 is arranged on one side of the mounting frame 21 facing the head or tail of the toy car 100, and guide wheels 221 are respectively arranged at two ends of the guide wheel frame 22. The guide wheels 221 of the toy vehicle 100 may be in rolling contact with the side walls 220 of the track so that the guide wheels 221 may act as guides to reduce friction between the wheels 211 and the track surface during cornering.

It will be appreciated that upon passing through a curve, toy vehicle 100 may easily collide with the inside surface of the track at the head or tail of toy vehicle 100, and the instantaneous speed of toy vehicle 100 at the point of contact with the inside surface of the track may decrease rapidly. The guiding wheels 221 just can form rolling friction between the toy car 100 and the side wall 220 of the track, so that the speed of the inner side of the toy car 100 is not excessively reduced, and the toy car 100 can smoothly drive through a curve, and the phenomenon that the toy car 100 is blocked and overturns at the curve is avoided.

Specifically, both ends of the guide frame 22 are provided with at least two guide wheels 221 spaced apart up and down, respectively. Here, a plurality of guide wheels 221 are provided at each end of the guide wheel frame 22 to be spaced apart up and down, and when either side of the toy vehicle 100 is in contact with the track side wall 220, the plurality of guide wheels 221 at that side can make the contact point of the toy vehicle 100 with the track side wall 220 more, so that the toy vehicle 100 is stressed smoothly, and thus the toy vehicle 100 is ensured not to be locked when turning on a heavy grade track or an inverted track.

Further, as shown in fig. 1 and 2, one side of the mounting frame 21 facing the head and tail of the toy car 100 is provided with a wheel frame 22, respectively, and each wheel frame 22 is provided with a top wheel frame 3. In this way, both the front and rear ends of toy vehicle 100 can be supported in contact with track top wall 230 via top wheel 33, avoiding the situation where wheels 211 are off the track as a result of the front or rear ends of toy vehicle 100 being tilted.

In the preferred embodiment of the present application, toy vehicle 100 is a four-drive vehicle, and four wheels 211 of toy vehicle 100 are each drive wheels, with wheel carriers 3 at the front and rear ends of toy vehicle 100.

In other embodiments of the application, however, toy vehicle 100 may be a two-wheel drive vehicle or other type of toy vehicle 100, model toy vehicle 100.
