Description

Technical Field

[0001] The utility model relates to the technical field of safety protection devices, in particular to a buffer safety protection device for trucks. Background Art

[0002] Safety protection devices are an important part of the structure of modern automobiles. When a car collision occurs, safety protection devices can effectively reduce casualties and damage to the car. It is divided into external protection devices and internal protection devices. The external protection devices are designed to gradually deform the car body when a collision occurs to absorb most of the impact energy generated in the accident. After the car body is changed to this deformable design, the strong impact force borne by the driver and passengers can be greatly reduced.

[0003] Many existing large trucks have flat front designs. Although this type of front structure can give the driver a wider field of vision and reduce the turning radius of the vehicle, it cannot provide sufficient body deformation in the event of a collision, so that the impact generated by the collision is transmitted to the driver and passengers to a large extent, causing greater harm to the driver and passengers. Therefore, a safety protection device that can be applied to flat-head trucks to improve the protection performance is proposed. Utility Model Content

[0004] The utility model aims to provide a truck buffer safety protection device to solve the above problems existing in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A truck buffer safety protection device includes a fixing seat for installation on the front of the vehicle, a clamping cover is inserted on the outside of the fixing seat, and the side walls of the fixing seat and the clamping cover are provided with connecting holes and grooves. The clamping cover is fixed by connecting pins inserted into the connecting holes and grooves on the fixing seat and the clamping cover, a spring member and a docking pad are fixedly installed on the inner bottom wall of the fixing seat at intervals, a solid ball is fixedly installed on the inner bottom wall of the clamping cover corresponding to the docking seat, and the connecting pin is made of brittle steel.

[0007] The beneficial effect of the utility model is as follows: when a truck collides at the front of the vehicle, a displacement tendency occurs between the fixing seat and the clamping cover, and part of the impact force is converted into a shear force acting on the connecting pin. The connecting pin is made of brittle steel and breaks under the action of the shear force. Then the fixing seat and the clamping cover lose their relative limit, and the spring member is clamped. The clamping force of the spring member is released to offset part of the impact force of the collision. The impact force that cannot be offset causes the spring member to deform and absorb part of the impact force. When the contraction of the spring member reaches the limit position, the solid ball will contact the docking pad and then offset part of the impact force, so that an effective impact resistance effect is obtained between the clamping cover and the fixing seat, thereby reducing the impact force transmitted to the vehicle occupants.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, one end of the spring member away from the inner bottom wall of the fixing seat is movably connected to the inner bottom wall of the pressing cover.

[0010] Furthermore, a thread is provided on the outer wall of one end of the connecting pin, and a fastening nut is threadedly installed on the threaded end of the connecting pin, and the other end of the connecting pin passes through the connecting hole and extends into the fixing seat.

[0011] Furthermore, the solid ball and the docking seat are made of tungsten steel, and an arc-shaped groove is provided on a side of the docking seat opposite to the solid ball, and the shape of the solid ball is adapted to the arc-shaped groove.

[0012] Furthermore, the fixing seat and the pressing cover are made of stainless steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figures 1 to 3 As shown, embodiment 1 of the utility model is a truck buffer safety protection device, including a fixing seat 1 for installation on the front of the vehicle, a clamping cover 5 is plugged into the outside of the fixing seat 1, and the side walls of the fixing seat 1 and the clamping cover 5 are provided with connecting holes 8, and the clamping cover 5 is fixed by connecting pins 6 inserted into the connecting holes 8 on the fixing seat 1 and the clamping cover 5, and a spring member 2 and a docking pad seat 3 are fixedly installed on the inner bottom wall of the fixing seat 1 at intervals, and a solid ball 4 is fixedly installed on the inner bottom wall of the clamping cover 5 corresponding to the docking seat 3, and the connecting pin 6 is made of brittle steel.

[0020] When the truck collides at the front of the vehicle, a displacement tendency occurs between the fixing seat 1 and the clamping cover 5, and part of the impact force is converted into shear force acting on the connecting pin 6. The connecting pin 6 is brittle steel and breaks under the action of the shear force. Then the fixing seat 1 and the clamping cover 5 lose their relative limit, and the spring member 2 is clamped. The clamping force of the spring member 2 is released to offset part of the impact force of the collision. The impact force that cannot be offset causes the spring member 2 to deform and absorb part of the impact force. When the contraction of the spring member 2 reaches the limit position, the solid ball 4 will contact the docking pad 3 and offset part of the impact force, so that an effective impact resistance effect is obtained between the clamping cover 5 and the fixing seat 1, thereby reducing the impact force transmitted to the vehicle occupants.

[0021] In addition, the fixing seat 1 can be installed and connected to the vehicle head by welding or riveting.

[0022] Embodiment 2 of the utility model is a truck buffer safety protection device. On the basis of embodiment 1, one end of the spring member 2 away from the inner bottom wall of the fixing seat 1 is movably connected to the inner bottom wall of the clamping cover 5.

[0023] The pressing cover 5 serves as an impact surface and is in contact with the spring member 2 . Therefore, when the pressing cover 5 is impacted, it pushes the spring member 2 to contract, thereby alleviating the impact force.

[0024] Embodiment 3 of the utility model is a truck buffer safety protection device. On the basis of embodiment 1 or 2, the outer wall of one end of the connecting pin 6 is provided with a thread, and the threaded end of the connecting pin 6 is threadedly installed with a fastening nut 7, and the other end of the connecting pin 6 passes through the connecting hole groove 8 and extends into the fixing seat 1.

[0025] The fastening nut 7 is used to position the connecting pin 6, so that the entire device has the characteristics of being detachable and easy to replace.

[0026] Embodiment 4 of the utility model is a truck buffer safety protection device. Based on any one of embodiments 1 to 3, the solid ball 4 and the docking pad 3 are made of tungsten steel, and an arc-shaped groove is provided on the side opposite to the docking pad 3 and the solid ball 4, and the shape of the solid ball 4 is adapted to the arc-shaped groove.

[0027] The solid ball 4 and the docking cushion 3 have higher hardness and strength requirements as rigid supporting structures, so they are made of tungsten steel. The corresponding shape design can also resist pressure and impact well, achieving the best protection effect in the most cost-effective way.

[0028] Embodiment 5 of the utility model is a truck buffer safety protection device. Based on any one of embodiments 1 to 4, the fixing seat 1 and the clamping cover 5 are made of stainless steel.

[0029] The main structure fixing seat 1 and the clamping cover 5 installed outside the vehicle body will almost certainly deform when impacted, so stainless steel is used, which can have a certain corrosion resistance and can also serve as a protective structure with a certain strength.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
