Meanwhile, in the present embodiment, only the locking process of the door lock is described, and for the unlocking of the door lock, the structure for driving the locking plate 2 and the pawl 3 to perform the unlocking motion, and the specific unlocking process, are also referred to the door lock structure in the existing automobile.

In the door lock structure of the present embodiment, when the door is locked, the movement processes of the lock catch 5, the catch plate 2 and the pawl 3 are as shown in fig. 3 to 5. Fig. 3 shows that the lock catch just enters the locking groove 203 and contacts with the inner wall of the locking groove 203, the contact position is the first sound impact point position a on the locking groove 203, and at this time, the first impact sound is generated due to the collision between the lock catch 5 and the card board 2 at the first sound impact point position a.

Fig. 4 shows that as the lock catch 5 enters the locking groove 203, the card board 2 is driven to rotate, so that the half-lock arm 201 is clamped into the slot 301 of the pawl 3 to achieve a half-lock state under the action of the spring 4. At this time, the half-lock arm 201 entering the card slot 301 contacts the pawl 3 at the second sound impact point position b, and a second impact sound is generated due to the collision of the half-lock arm 201 and the pawl 3 at the second sound impact point position b.

Meanwhile, the abutting arm 204 of the card board 2 abuts against the limit post 8. At this time, since the card board 2 simultaneously contacts and collides with the pawl 3 and the stopper post 8, there are two third sound impact point positions c, one of which is located between the full-lock arm 202 and the pawl 3, and the other is located between the abutting arm 204 and the stopper post 8.

In the door locking process shown in fig. 3 to 5, it should be noted that the mechanical feeling in the door closing sound is mainly related to the impact at the first sound impact point position a, the second sound impact point position b, and the two third sound impact point positions c. Moreover, the mechanical sensation in the door closing sound is particularly related to the impact loudness difference at the first and second acoustic impact point positions a, b, and the impact time interval and impact loudness difference at the second and third acoustic impact point positions b, c.

At this time, referring to fig. 6, a position where the lock groove 203 collides with the lock catch 5 due to the entrance of the lock catch 5 is defined as an engagement point g, which is located at the first sound impact point position a. And in the specific design, the movement direction of the lock catch 5 when the lock catch 5 collides with the locking groove 203 and the tangential direction of the position of the meshing point g are also enabled, and the included angle η between the two directions satisfies the following conditions: eta is less than or equal to 35 degrees.

In specific implementation, the angle η may be, for example, 15 °, 20 °, 25 °, 30 °, or 35 °. Meanwhile, it should be noted that, when the latch 5 enters the notch 101 and contacts the card board 2 as the vehicle door is closed, since the arc corresponding to the movement stroke of the latch 5 in the notch 101 is small with the vehicle door hinge as the rotation center, as shown in fig. 6, the movement direction of the latch 5 in the notch 101 can be regarded as the depth direction of the notch 101. Thus, the angle η is also shown in fig. 6, and the striking force applied by the lock catch 5 to the card board 2 is along the moving direction of the lock catch 5, and the two components of the striking force applied by the lock catch 5 are respectively in the tangential direction along the position of the engagement point g and in the direction perpendicular to the tangential direction.

In this embodiment, the included angle η is set to be η or less than 35 °, so that the component force in the direction perpendicular to the tangential direction can be reduced, the loudness difference between the impact of the lock catch 5 and the clamping plate 2 and the first impact of the clamping plate 2 and the pawl 3 can be ensured, the impact noise between the lock catch 5 and the clamping plate 2 can be reduced, the reaction force of the clamping plate 2 to the lock catch 5 is reduced, and the lock catch 5 can be smoothly cut into the locking groove 203.

As shown in fig. 7, in this embodiment, the position where the half-lock arm 201 collides with the pawl 3 when being inserted into the card slot 301 is defined as a half-lock arm collision point d, and similarly, the position where the full-lock arm 202 collides with the pawl 3 when being inserted into the card slot 301 is defined as a full-lock arm collision point e. In the door lock structure of the present embodiment, the half-lock arm striking point d and the full-lock arm striking point e are located on the same arc using the rotation center of the card 2 as the center of the circle, and the arc length L between the half-lock arm striking point d and the full-lock arm striking point e is t × v.

Wherein, t is the time interval of the impact between the second sound impact point position b and the third sound impact point position c, and generally t should be between 0.018 and 0.025s, v represents the minimum closing speed of the vehicle door, and generally v should be between 1.0 and 1.25 m/s. In this embodiment, by setting the arc length between the half-lock arm striking point d and the full-lock arm striking point e, the time interval between the striking of the half-lock arm 201 and the full-lock arm 202 with the pawl 3 can be within the above preferred range, which is favorable for improving the mechanical feeling in the striking sound of the card board 2 and the pawl 3.

In addition, as shown in fig. 8 and 9, the present embodiment has a critical point f on the pawl 3 on one side of the card slot 301, which is specifically on the side of the card slot 301 close to the catch 5, and the half lock arm 201 and the full lock arm 202 rotate with the card 2 and slide past the critical point f and then enter the card slot 301. Furthermore, when the semi-locking arm 201 is at the critical point f, an angle θ is formed between a tangent line of a connection point between the pawl 3 and the spring 4 and a longitudinal direction of the spring 4₁When the arm 202 is at the critical point f, the angle θ is formed between the tangent of the connection point between the pawl 3 and the spring 4 and the length direction of the spring 4₂. In terms of specific design, the present embodiment is preferableWill make the angle theta equal to₁And angle theta₂Is set to theta₁≤θ₂。

Wherein, still referring to fig. 8 and 9, the present embodiment is achieved by setting θ₁≤θ₂The force exerted by the spring 4 on the pawl 3 when the full lock arm 202 is at the threshold point f is greater than the force exerted by the spring 4 on the pawl 3 when the half lock arm 201 is at the threshold point f, based on the common use of the spring 4 between the catch plate 2 and the pawl 3. Therefore, larger impact force can be generated between the full-lock support arm 202 and the pawl 3 and between the abutting arm 204 and the limit column 8, so that the impact loudness difference between the second sound impact point position b and the third sound impact point position c is ensured, the impact at the third sound impact point position c is favorably highlighted, and the mechanical feeling of the door closing sound is improved.

The loudness curve of the door lock structure of the present embodiment when the door is closed is shown in fig. 10, and the loudness curves in fig. 10 sequentially represent, from low to high, the impact loudness at the first acoustic impact point position a, the second acoustic impact point position b, and the third acoustic impact point position c. As can be seen from fig. 10, the design of the door lock structure can improve the loudness at each position, and can particularly highlight the impact loudness at the second sound impact point position b and the third sound impact point position c, so as to facilitate the improvement of the mechanical feeling in the door closing sound.

And the door lock structure of this embodiment is through cardboard 2 and the pawl 3 of rotation setting for spring 4 lug connection is between cardboard 2 and pawl 3, and makes cardboard 2, pawl 3 and spacing post 8 adopt cast iron or stainless steel. From this, can be when the door is closed for the impact between cardboard 2 and pawl 3 and the spacing post 8 is big, and the sound machinery of closing the door feels obvious, can promote the use quality of car.
