Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a buffering and shock absorbing structure and a vehicle. Background Art

[0002] At present, new energy vehicles that rely on power batteries as driving energy have developed rapidly in recent years due to their lack of harmful gas emissions and low noise during driving. However, due to the long charging time of the battery and the limited amount of power stored, the battery on the vehicle is usually replaced directly to achieve long-term driving of the vehicle. To this end, a locking mechanism that matches the battery frame is provided on the vehicle, and the battery box is placed in the battery frame. The battery box is fixed and replaced by the locking and unlocking states of the locking mechanism. However, since the locking mechanism of the vehicle is always rigidly in contact with the battery frame during use, the vibration of the battery exchange system (including the battery exchange base, battery frame, etc.) causes repeated collisions between the locking mechanism and the battery frame when the road is bumpy, the vehicle accelerates and decelerates, and turns. The collision causes the locking mechanism and the battery frame to bear a large impact load, thereby damaging the surface of the locking mechanism and the battery frame, affecting the service life and reducing the safety of vehicle driving. Summary of the invention

[0003] One of the purposes of the present invention is to provide a buffering and shock-absorbing structure that can reduce the impact load received by the battery frame and the locking mechanism during vibration, extend the service life of the battery frame and the locking mechanism, and ensure the safety of vehicle driving.

[0004] In order to achieve the above technical effects, the technical solution of the present invention is as follows:

[0006] The locking mechanism comprises a pressing head and a suspension end connected to each other, wherein the pressing head is located above the pressing part and abuts against the pressing part;

[0023] The beneficial effects of the present invention are as follows: the present invention provides a buffering and shock-absorbing structure, which can keep the locking mechanism pressed on the battery frame when there is a dimensional error or vibration in the battery frame, thereby avoiding a gap between the battery frame and the locking mechanism; when the battery frame vibrates upward, the battery frame pushes the pressure head to move upward, thereby driving the locking mechanism to move upward, so that the suspended end presses the buffer mechanism, and the buffer mechanism is further pressed upward to achieve vibration buffering, thereby avoiding direct impact on the battery frame, the locking mechanism and the battery exchange base during vibration under the rigid condition of the battery frame, the locking mechanism and the battery exchange base, protecting the locking mechanism and the surface of the battery frame from damage, extending the service life of the battery frame and the locking mechanism, and ensuring the safety of vehicle driving.

[0049] Embodiment 1

[0050] like Figure 1 and Figure 2 As shown, this embodiment provides a battery swap vehicle, which includes a vehicle body and a buffer shock absorbing structure, and the buffer shock absorbing structure is arranged on the vehicle body. Specifically, the buffer shock absorbing structure includes a battery frame 1, a locking mechanism 2, a battery swap base 3 and a buffer mechanism 4, wherein: the battery frame 1 is used to carry the battery system, including a bearing surface and a crimping portion arranged oppositely, the locking mechanism 2 includes a connected pressure head 21 and a suspension end 22, the pressure head 21 is located above the crimping portion and can abut the crimping portion to apply a locking force to the battery frame, the battery swap base 3 is fixed on the frame of the battery swap vehicle, the battery frame 1 is arranged between the pressure head 21 and the battery swap base 3, and the battery frame 1 and the battery swap base 3 are arranged between the pressure head 21 and the suspension end 22, that is, the pressure head 21 and the suspension end 22 crimp the battery frame 1 on the battery swap base 3, the buffer mechanism 4 is arranged between the battery swap base 3 and the suspension end 22, and the suspension end 22 can reciprocate along the buffering direction of the buffer mechanism 4.

[0051] It can be understood that when the battery frame 1 vibrates, the suspended end 22 of the locking mechanism 2 can reciprocate in the buffering direction through the buffering mechanism 4, thereby driving the pressure head 21 of the locking mechanism 2 to reciprocate in the buffering direction, and then when the battery frame 1 is vibrated, the pressure head 21 of the locking mechanism 2 can move in the same direction as the battery frame 1, thereby avoiding the collision caused by the vibration of the battery frame 1 and the pressure head 21 of the locking mechanism 2 not moving, protecting the locking mechanism 2 and the surface of the battery frame 1 from damage, extending the service life of the battery frame 1 and the locking mechanism 2, and ensuring the safety of vehicle driving. For example, when the battery frame 1 vibrates upward, the battery frame 1 pushes the pressure head 21 to move upward, thereby driving the locking mechanism 2 to move upward, so that the suspension end 22 presses the buffer mechanism 4, and the buffer mechanism 4 further presses upward to achieve vibration buffering, thereby avoiding direct impact on the battery frame 1, the locking mechanism 2 and the battery exchange base 3 during vibration when the battery frame 1, the locking mechanism 2 and the battery exchange base 3 are rigidly connected. The impact load received by the battery frame 1, the locking mechanism 2 and the battery exchange base 3 is reduced, the damage to the contact surfaces of the three is reduced, and the service life is extended.

[0052] Among them, the buffer shock absorbing structure also includes a fixing part 5, which is installed outside the locking mechanism 2, and the buffer mechanism 4 is connected to the battery swap base 3 through the fixing part 5. In this embodiment, the fixing part 5 includes a vertical section and a horizontal section connected to each other, the vertical section is in contact with the locking mechanism 2, and the horizontal section is in contact with the battery swap base 3, so as to facilitate the installation of the fixing part 5 while avoiding interference with the battery swap base 3 and the suspension end 22 of the locking mechanism 2, and the L-shaped through groove formed by the vertical section and the horizontal section can guide the installation of the fixing part 5. In addition, the buffer mechanism 4 is connected to the battery swap base 3 through the fixing part 5, which can not only reduce the damage caused by the direct installation of the buffer mechanism 4 on the surface of the battery swap base 3, but also facilitate maintenance.

[0053] Specifically, the buffer mechanism 4 includes a guide column 41 and an elastic part 42. Both ends of the guide column 41 are respectively connected to the battery swap base 3 (when the fixing part 5 is provided, both ends of the guide column 41 can be connected to the fixing part 5 instead of being directly connected to the battery swap base 3), and pass through the suspension end 22. The elastic part 42 is provided between the suspension end 22 and the battery swap base 3 and is sleeved outside the guide column 41. The suspension end 22 is driven to reciprocate along the buffering direction through the deformation of the elastic part 42. It can be understood that when the locking mechanism 2 is in a locked state, the pressure head 21 is pressed downward and the suspension end 22 is pressed upward, so that the elastic part 42 is pressed and is in a compressed state to generate a locking force. The locking force presses the battery frame 1 onto the battery exchange base 3 through the pressure head 21. If the battery frame 1 is vibrated upward, the battery frame 1 contacts the pressure head 21 and exerts an upward thrust on the pressure head 21, thereby driving the suspension end 22 to continue to move upward, and then the elastic part 42 continues to compress to absorb the energy of vibration and impact, thereby achieving a shock absorbing and buffering effect. When the battery frame 1 is vibrated downward, the battery frame 1 will Separated from the pressure head 21, the force applied on the pressure head 21 disappears, so that the suspension end 22 moves downward under the action of the rebound force generated by the compression of the elastic part 42, and then drives the pressure head 21 to move downward to continue to press the battery frame 1, ensuring that the pressure head 21 can always press the battery frame 1 during the vibration process while avoiding hard contact between the two as much as possible. When the locking mechanism 2 is in the unlocked state, the suspension end 22 moves downward under the action of the rebound force generated by the compression of the elastic part 42 until the elastic part 42 is in a free state. At this time, the lower surface of the suspension end 22 is in contact with the battery replacement base 3 through the fixing part 5. Exemplarily, the elastic part 42 is a disc spring or a spring. That is, the spring or disc spring is sleeved outside the guide column 41, and the guiding effect of the guide column 41 can prevent the elastic part 42 from bending when it is compressed, thereby ensuring the normal operation of the buffer mechanism 4.

[0054] In this embodiment, one end of the elastic part 42 is connected to the suspension end 22, and the other end is connected to the battery exchange base 3 through the fixed part 5. The buffer mechanism 4 also includes an upper limit plate 43 and a lower limit plate 44. The upper limit plate 43 is installed on the upper surface of the suspension end 22, and the lower limit plate 44 is installed on the side of the fixed part 5 away from the battery exchange base 3 and is located below the suspension end 22. That is, the lower limit plate 44 is used to reduce the distance between the elastic part 42 and the suspension end 22, and the elastic part 42 is pre-pressed, thereby generating a certain pre-tightening force on the suspension end 22 and the pressure head 21. The upper limit plate 43 is set to limit the compression amount of the elastic part 42, so as to avoid the elastic part 42 being over-compressed due to external force, resulting in poor performance and reduced durability. Exemplarily, the upper limit plate 43 and the lower limit plate 44 are both made of rubber material. Of course, in other embodiments, the upper limit plate 43 and the lower limit plate 44 can also be made of other elastic materials, which are not specifically limited in this embodiment.

[0055] Further, in order to ensure the stability of the suspension end 22 moving along the buffering direction, the number of the elastic parts 42 and the guide pillars 41 are both provided in multiple numbers. Preferably, the elastic parts 42 and the guide pillars 41 correspond one to one, and the multiple elastic parts 42 can be distributed in an array or in other distribution forms. It can be understood that the number and specific distribution of the elastic parts 42 and the corresponding guide pillars 41 can be designed according to actual conditions, and this embodiment does not impose specific restrictions.

[0056] Furthermore, the buffering and shock absorbing structure further includes a dust cover 6, which is installed outside the buffering mechanism 4 and can cover the suspension end 22. That is, the dust cover 6 is detachably connected to the fixing portion 5, so that the buffering mechanism 4 and the suspension end 22 are both covered in the dust cover 6, so as to prevent dust and other impurities in the external environment from entering the buffering mechanism 4, thereby affecting the buffering and shock absorbing effect.

[0057] Furthermore, the buffering and shock-absorbing structure provided in the present embodiment can always keep the battery frame 1 and the battery exchange base 3 locked when the battery frame 1 vibrates, but it can only play a buffering and shock-absorbing effect when the battery frame 1 vibrates upward. When the battery frame 1 vibrates downward, the battery frame 1 will still directly collide with the battery exchange base 3. Therefore, in some embodiments, a buffer pad (not shown) is arranged between the battery frame 1 and the battery exchange base 3 to provide buffering when the battery frame 1 vibrates downward.

[0058] Embodiment 2

[0059] A buffering and shock absorbing structure is provided in this embodiment, which is substantially the same as the structure of the first embodiment. The difference between the two is the buffering mechanism 4. Only the difference between the two is described here, and the same structure between this embodiment and the first embodiment is not repeated here.

[0060] Specifically, considering that the buffer mechanism 4 actually needs to perform buffering and shock absorption in two directions: upward and downward, elastic parts 42 should be provided on both sides of the suspension end 22, that is, the elastic part 42 includes an upper elastic part and a lower elastic part (not shown), the upper elastic part is provided between the upper surface of the suspension end 22 and the electric base 3, and the lower elastic part is provided between the lower surface of the suspension end 22 and the electric base 3.

[0061] More specifically, Figures 3 to 5As shown, in order to minimize the number of parts of the buffer mechanism 4, the upper surface and the lower surface of the suspension end 22 in this embodiment are respectively fitted with the battery swap base 3 through the elastic part 42. That is, one end of at least one elastic part 42 is connected to the upper surface of the suspension end 22, and the other end is connected to the battery swap base 3 through the fixing part 5, and one end of at least one elastic part 42 is connected to the lower surface of the suspension end 22, and the other end is connected to the battery swap base 3 through the fixing part 5. The elastic part 42 is provided on both the upper surface and the lower surface of the suspension end 22, so that the upper limit plate 43 and the lower limit plate 44 are not required.

[0062] In this embodiment, combined with Figure 3 and Figure 4 As shown, the elastic portion 42 is a rubber pad. Figure 5 and Figure 6 As shown, the elastic portion 42 is a leaf spring.

[0063] In order to ensure the stability of the suspension end 22 moving along the buffering direction, a plurality of guide pillars 41 are provided, and the plurality of guide pillars 41 can be distributed in an array or in other distribution modes (specifically, it can be determined according to information such as the force conditions of the guide pillars. It can be understood that the number and specific distribution of the guide pillars 41 can be designed according to actual conditions, and this embodiment does not impose any specific restrictions.

[0064] Embodiment 3

[0065] This embodiment provides a buffering and shock absorbing structure, which is mainly different from the above-mentioned embodiment in that: a load-bearing end 23 is further provided in the locking mechanism 2, specifically, as shown in FIG. Figure 7 and Figure 8 As shown, in the buffering and shock absorbing structure provided in this embodiment:

[0066] The locking mechanism 2 further includes a load-bearing end 23 disposed between the pressing head 21 and the suspension end 22 . The load-bearing end 23 abuts against the load-bearing surface to cooperate with the pressing head 21 to press the battery frame 1 .

[0067] In this embodiment, the battery frame 1 is still arranged between the pressure head 21 and the battery exchange base 3, but a new load-bearing end 23 is newly arranged between the battery exchange base 3 and the battery frame 1, so that the battery frame 1 does not need to directly contact the battery exchange base 3: the battery frame 1 is subjected to locking force from the crimping part and the load-bearing surface respectively by the pressure head 21 and the load-bearing end 23, so that the battery frame 1 is directly fixedly connected to the locking mechanism 2, and then the locking mechanism 2 is fixed between the battery exchange base 3 and the buffer mechanism 4 through the suspension end 22. This structure can achieve a buffering and shock-absorbing effect no matter which direction the battery frame 1 vibrates, by means of the buffer mechanism 4, by realizing reciprocating motion in the buffer direction, thereby avoiding a large amount of impact load caused by direct impact: when the battery frame 1 vibrates upward, the battery frame 1 presses the pressure head 21 upward, thereby driving the locking mechanism 2 to move upward, so that the suspended end 22 of the locking mechanism 2 presses the buffer mechanism 4 upward, and the elastic part 42 is further compressed upward to achieve buffering and shock absorption; when the battery frame 1 vibrates downward, the battery frame 1 presses the load-bearing end 23 downward, thereby driving the locking mechanism 2 to move downward, so that the suspended end 22 of the locking mechanism 2 presses the buffer mechanism 4 downward, and the lower limit plate 44 is further compressed downward to achieve buffering and shock absorption.

[0068] In the description of this specification, the description with reference to the terms "some embodiments", "other embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0069] The above contents are only preferred embodiments of the present invention.
